Chapter Text

It was an accident. Close calls weren’t exactly rare, considering there were three bathrooms for six of you. Luckily, you joked, since it was one woman here to five men, they tended to pee quicker than you, and you managed.

Today, though, seemed like it was your poor luck.

The bathroom attached to the master that Katsuki and Izuku shared was locked, the shower running loudly. You sighed and went to the hall bathroom that you typically showered in. But that door was locked, and Denki’s hype-playlist was playing loudly. He was singing along, not a prayer of hearing you knock.

Okay, you thought, feeling a cramp in the pit of your belly. You had waited too long, you thought. You rushed for the three quarter bath that was usually used by Kirishima, since it was closest to his room. You didn’t favor it, liking to be able to soak in the tub rather than take a shower.

You could hear the water running, with strange patterings mixed in. You realized Kirishima said he had some things to hand rinse before they went into the washer. Usually workout gear that he wanted to pre-treat before washing.

You whimpered in the hallway, crossing your legs. You chewed your lower lip as you bounced on your toes. You were afraid to move, you thought. You’d piss immediately. You focused on breathing, trying hard to distract yourself.

Think dry thoughts, you told yourself. Think about anything other than the pressure in your bladder and how if you even sneezed you were going to be soaking wet. It couldn’t be much longer, you thought. Someone had to come out soon. You just had to try hard enough, and things were going to be fine.

But the water never stopped running. It amazed you that you had enough water pressure to run two showers at once. It would have been amazing, if it wasn’t making you want to pee even more.

You pounded at Kirishima’s bathroom door, smacking it with the flat of your palm. By now you had your hand between your legs, like a little child. You were dancing from foot to foot, despeate and aching.

You couldn’t blame yourself when you felt the piss trickling out. A tiny bit at first, just a few drops. But once your body knew there was a path to relief, it wasn’t going to take no for an answer. You stood in the hallway, thankful somewhere in the back of your mind that the floor was not carpeted.

Your jeans were soaked. Wet tracks made their way down your thighs, your knees, all the way to your ankle. Of course the air in the apartment was a little dry, giving you dry mouth, which meant that you had been drinking so much water. Piss puddled at your feet, soaking your slippers.

It was hot, you thought. It was hot, and you smelled like piss, and you hated it. Without another word, you were sobbing, shame washing over you. You heard a door open, glanced up to see Denki peeking down the hall.

“Princess!” he gasped. “What’s wrong, what–? Ooohhh,” he saw your filthy state and the lightbulb went off.
“Why didn’t you knock, hon? I was just getting ready.”

“Because your music was so loud!” you shouted. “I did knock, I did! And Izuku had his shower going so he couldn’t hear me. And I’m not sure why Eiji didn’t,” tears, salty, hot, and shameful were rolling down your cheeks.

“It’s okay,” he soothed in a delicate voice. “It was just an accident, you’re okay. You’re okay.” he was patting you right between your shoulders. The door swung up and you moaned, closing your eyes tightly.

“Huh? What’s going on?” Kirishima took in the scene, holding a bin of wet laundry. He looked at you, his mouth making a perfect ‘o’.
“I am so sorry!” he blurted. He juggled the pin and reached up to take an ear bud out. “I had my headphones in.”

“She’ll be fine,” Denki tried to soothe the redhead who looked just as upset now. You whined, your jeans feeling clammy and gross, your skin starting to itch.

“Let me get you all cleaned up,” Eijirou put down the bin and held out his hands. “Denks, can you get the floor cleaned up?”

“Of course,” he went to hurry off. You shook your head, trying to snatch him.

“No, it’s my mess, it’s gross, I’ll do it, I’ll do it.” you babbled.

“No, YOU are going to get cleaned up and get in the tub.” Eijiro shook his head. He steered you away from the puddle and took you to the hall bathroom. You tried to bat his hands away when he went to pull your top off.
“Honey, honey, stop.” he grabbed your wrists.

“I’m sorry,” you whispered. “I didn’t mean to.”

“I know that. It was my fault.” he stroked your hair back from your face. It was a pacifying gesture. “Just breathe. No big deal. It happens to everyone.” he sat on the edge of the tub, flicking on the shower.
“There we go, let me take your pants off and then we’ll get you cleaned up. While you soak in the tub I’ll go and get you clean clothes.”

“Eijirou,” you whined, sniffling. He made shushing sounds and helped you step into the tub. He took the hose and nudged your legs apart. You bit your lip as he adjusted the shower head and rinsed you down.

“Good, you don’t have any kind of rash.” he murmured. He grabbed your plain soap and washed your legs, rough hands gentle on the thin skin of your thighs. He rinsed you again and paused, his cheeks pink.
“Uh, hon? Your bottom got wet…”

“I know, I was there.” you snapped.

“No, I mean, I need to get that cleaned off too.”

“I can do it!” you insisted.

“But I’m already here and you’re upset.” he was turning you himself. You put your hands to the tile wall and squeezed your eyes shut, feeling him carefully soap your asscheeks and rinse those off, too.
“It’s no big deal. How many times have we seen each other naked, huh? And how many times have you had to help patch us up after fights? It’s the same thing.”

When you were soap free, he stood you on the rug, wrapping a towel around you. He rubbed your hips and gave you one of his bright smiles, the same kind that you used to call his golden retriever smile.

You watched, still sniffling a little bit as he started the tub. He reached under the sink and pulled out a bottle that you didn’t remember buying. There was a smiling pink bubble on it, and you watched as Eijirou poured in a healthy amount, then swished his hand around, the bubbles growing.

“I haven’t used that kind of bubble bath in years.” you said.

“I know, but it was on sale last time I was at the store. And I just figured, well, for the price…” he shrugged.
“It’s the perfect temp, baby, your favorite. Get in the water and relax. I’ll go and get your clean clothes.”

You let the towel fall. Eijirou was right; all of you saw each other naked a lot. Them more than you, you allowed. Sometimes Hanta came in with pain in his shoulders from the poses he had to use for his tape. He’d be topless, waiting for you to rub the medication cream into his shoulders.

Izuku and Katsuki ran super hot, and they had been known to strip down to just their boxers. When Eijirou was working out, he’d be mostly naked, walking around sweaty with his towel around his neck.

And you, of course, would sometimes ask for help with zippers in the backs of your dresses, or for bras to be clasped just so. You’d even had fashion shows for them now and then when you bought new things.

But still, you thought. You’d full on pissed your pants like a little kid. And you had sobbed about it, and let someone else clean you up. It was horrible, you thought, your face hot at the idea. You scooped up some of the bubbly foam and blew it from your palm, giggling gently.

“Good to hear you laugh,” the door opened. Eijiro was holding a bundle of clothes. He sat down on the rug, looking at you.
“I am sorry, princess. I should have heard you knocking. It wasn’t your fault. Denks got the hall cleaned, I tossed your dirty stuff in the washer. Everything is fine.”

You sighed and looked down at the water. After a few minutes, Eijirou stood up and held out a hand, helping you sound. He grabbed your towel and helped you out, dried you off. You were much more relaxed, letting him pat you dry. He reached for the pile, holding open a pair of underwear.

“I can dress myself.” you muttered. Eijirou shrugged. He slid the panties up your legs to settle at your hips. He had a pair of sweats, and one of his old long sleeved shirts for you. You were quickly dressed and he was ushering you out.

“You okay?” Izuku was waiting, concerned.

“Oh my God, did we have to tell him?” you asked no one in particular.

“Hey, it isn’t to tease you. Just to make sure you’re not sick. You don’t have a fever or painful pee?” he grabbed your shoulders, leaning down to press his lips to your forehead.
“No fever," he mused.

“I’m fine, it’s fine, it was just–an accident.” you sounded a little choked. “Can we pretend that nothing happened?”

“As long as you’re not sick.” he glanced at the clock. “Denks! You need to get going or you’ll be late for your shift.”

“I know!” the blond called back. He appeared with his jacket, stuffing his keys in his pocket. He hugged the other two, then grabbed you and kissed your temple. He was gone quickly, and you padded to the living room, ready to curl on the couch and be left alone.

Chapter Text

The next few days, you were able to pretend it hadn’t happened. The music was turned down when Denki was getting ready, everyone else promised not to have both ear buds in. So you could avoid all of that nonsense again.

You had the smallest room in the house. It was likely a storage alcove at one point. Your room didn’t have heat, but it did have a window that showed the most beautiful tree. You got to watch the changing of the seasons through that window, your favorite being autumn when the leaves all changed colors.

Izuku and Katsuki shared. Kirishima had his own room. Hanta and Denki shared. There was another bedroom, but that was reserved for three computer desks, for work from home days. You didn’t mind having the worst bedroom, you insisted. After all, any of them were happy to let you sleep in their room if you really wanted to.

Many times you’d gone to have a movie night with someone and fallen asleep in their bed. Or went to go and read in their rooms, to stave off loneliness. And no one ever pushed you out. Katsuki was even known to tuck you back in when he had to leave in the morning, encourage you to cuddle with Izuku.

You had been in your own room, though. With your twin size bed and your one chest of drawers. There was just enough space for a hanging rack for your dresses. You did pin up a gauzy canopy over your bed, string up some fairy lights for ambiance. But you couldn’t keep too many books or anything else in your room, not really.

Waking up, feeling damp and clammy was scary. You almost never had nightmares. You liked to joke that you lived with five pro heroes. What did you have to be scared of? So you couldn’t even blame it on a nightmare. Your hand went down the bed, feeling the large wet spot. Your face burned as you shoved down the sticky sheets.

You hadn’t peed the bed since you were a little girl. Your hands were shaking as you got off the bed. Slowly, carefully, you peeled off the sheets and made your way to the little laundry room off the kitchen.

But of course, Denki had been doing laundry, so that meant that the dryer was full of stuff to be folded so the stuff in the washer could go in. And only then would you be able to shove your sheets and blanket in there.

And your pajama pants were clinging to your legs, itchy and gross. You sighed and grabbed all the clean laundry, beginning to fold it and put it in Denki’s that had been on top of the washer. You tried to move quickly. You stripped off your pajamas and added them to the washer, putting in some of the laundry sanitizer and starting the wash.

You stood, naked, in the laundry room holding the basket. There was a shuffling sound and a yawn. Denki was suddenly there, rubbing at his eyes.

“Hey princess,” he grinned sleepily. “Couldn’t sleep? I forgot to get my laundry. Thanks,” he grabbed the basket. “It’s late, you should get yourself to bed.”

“Iknowyou’rewelcomegoodnight.” you tried to zoom to your room. When Denki was woken in the middle of the night, he wasn’t known for being the brightest crayon in the box. You could probably skitter away without him really understanding what he was or was not seeing. Homefree!”

“Waaaait a minute,” Denki said just as you were halfway through the kitchen. You cringed and froze, waiting.
“I forgot to put in fabric softener! Oh well, maybe next time.” you were so relieved, you could have collapsed. You hurried to your room, grabbing a change of clothes and your one spare set of sheets.

***

But it wasn’t just that night, you realized. It was the next night. And the next. You were afraid to fall asleep, honestly. You tried everything! You went pee before bed. You set an alarm for two hours after you fell asleep to go pee. You tried restricting your fluids after dinner, to keep yourself from filling up.

No one noticed, not really, but it was exhausting. And you were running out of reasons to do so much laundry. You said you were sorting through clothes to find some stuff to donate. Then you were washing all the bathroom rugs. And now you were just hoping you could wake up before everyone else.

But there was the day that Izuku had to do all of his and Katsuki sheets. So you had your clean sheets on the bed and nothing else. You barely drank anything, no matter how dry your lips were. And you pissed two hours after you went to bed. Early, tonight, because you were so sick and tired of not getting a good night’s sleep.

It wasn’t that long, though. Probably thirty minutes after you had gotten up to pee. You woke up, sheets soaked around you. You groaned and rolled out of bed, balling up the material. You grabbed your other dirty sheets, heading to the laundry room.

Izuku had to be asleep by now. You could probably go ahead and lay on the couch. It wouldn’t be too strange? Or go back to bed with no sheets on. But your blankets were dirty, so you’d have to grab something from the living rom–.”

“What are you doing up?” Izuku’s voice shocked you out of your thoughts. You looked up at him, mouth working like a fish. He looked at your bottoms, still soaking wet, and the bedding in your hands.
“Oh, sweetie.” he sighed.

“I…I just…” you trailed off. He opened the washing machine and held out his hands. “No, I can do it, I can do it.” you assured him.

“You are exhausted. I’ve noticed for a few days, although I didn’t ask why. I didn’t think it was my business. But if this is keeping you up, then I think I should help you.” he took the sheets, stuffing them in, back turned while you peeled out of your pajamas.
“Come with me and I can get you cleaned up, then you can sleep with me and Kacchan.”

“Aren’t you scared I’ll wet your bed?”

“No, honey.” he gave you a sympathetic look, which honestly didn’t make you feel a whole lot better. Instead, he walked you to the nearest bathroom and got a soapy warm wash cloth to wipe you down. He examined the skin on your groin and frowned.
“You look sore here.”

“It’s fine!" You groaned. “I’m an adult and I will fix whatever I need.”

Izuku got you wiped clean and walked to the master bedroom he shared with Katsuki. Not because they deserved it more, but because Katsuki Bakugou was never going to let himself settle for less.

The green eyed hero took a pair of boxers out of his dresser, and a plain t shirt. You were so tired, you thought, rubbing your eyes. He coaxed you into laying down, your back against his chest, his arms wrapped around your waist.

“It’s gonna be okay.” he whispered. “We’ll figure out what the problem is, okay?”

Chapter Text

No one said anything to you about it the next day. But you knew they knew, because Katsuki made your very favorite soup for lunch. And Eijirou let you pick the television show. And when Hanta came back from work, he was carrying your favorite take out.

You wondered if a blush could become permanent.

Izuku came home, looking triumphant. You were ready to ask him how many villains he had taken down, but instead he beamed at you. He beckoned to you with one finger. You slid off the couch and followed him, feeling lightheaded. Something was going to happen, you could just tell. What you could not tell was what was supposed to be happening.

“I have a few things that I think are going to help!” he announced. You cleared your throat, crossing your arms. Izuku had a small bag with him, a little backpack that zipped neatly. He undid it and pulled out a blue backed bed pad, like they used in hospitals.
“Put this down before you go to sleep, and you won’t have to change sheets in the middle of the night. Be a lot less laundry for you, sweetie.”

“Thanks,” you said gruffly. But the hero wasn’t done yet, because he rummaged again and tossed you a box. You caught them and felt your face go on fire. It was a box of disposable incontinence pads.
“Izuku!”

“Now just a minute,” he held up a hand. “Recovery Girl has passed those out to all of us. We’ve all had some injuries that would make it hard to walk, or even make us pee a lot. This way we can all have dry pants.” he smiled.
“Just like putting in a pad.”

“Fine,” you huffed.

“We’ll see what happens. Maybe we’ll have to go back to the drawing board, but I can tell you’re tired, honey.” his voice had taken on a sweet tone. Your head fell and you sighed, looking at your feet.
“And you’re tired, aren’t you?”

“I guess,” you mumbled.

“Yeah?” he held out a hand. “Come here, honey. We can take a nap, get you well rested. You know that might be part of the problem? You can’t control your bladder because–.”

“Okay! Shut it! I don’t wanna talk about this! We can nap if you’ll stop talking about it.” you begged. Izuku beckoned you close to him. WIthout another word, he yanked you towards him. He yanked down your pants, hearing you yelp.
“Hey! What are you doing?”

“You’re right,” he hummed. “Go pee really quick and we’ll get you all ready for nap, won’t we?” Izuku didn’t pull your pants up, but helped you step out of them and gave you a pat on the bottom so you’d head to his ensuite.

You sat on the toilet, face in your hands, trying to breathe. This was gross! This was terrible! But the thought of sleeping through the night, without having to rush middle of the night laundry? It was tempting. You went back out bottomless. Izuku had grabbed your panties and placed in one of the pads. He held them open for you, saying nothing as you stepped into them.

“There! Now,” he laid out one of the pads on his bed. “Lay down with me, sweetie. I can tell that you are just exhausted, aren’t you?” he helped you into the bed, his own side. He slid in behind you, pressing his knees behind yours.

“Aren’t you scared I’ll wet your bed?”

“It’s okay if you do. We’ll clean you up.” he rubbed your belly. “Just hush, get some rest. You’ll seem better when you aren’t sleepy.” he nosed behind your ear. It was so warm, so comfortable, you couldn’t help but fall asleep?

***

“Hey, sh, you’re fine, it’s fine.” someone was telling you as they moved you around. You whined and went to push at him.
“I know, but you’re wet, babes. Let me get you dry and comfortable, and we’ll go and eat our supper, won’t we?”

“Huh?” you opened your eyes, feeling hazy. Izuku was peeling the wet incontinence pad from your underwear. You groaned, covering your face with your hands. “No!”

“But see? Because you had the pad, the bed is dry. No laundry. Isn’t that better?” he tossed the pad and laid in another.

“I’m awake!” you squawked.

“Just a precaution.” he soothed, wiping you with a warm cloth. “There we go. Lift your bottom for me.” he pulled up your panties and helped you sit up.
“I’ll get you some bottoms and we can head out for supper, okay?”

You watched, still feeling blurry as Izuku grabbed a pair of sweats and threaded your feet through. He pulled them up, rolling the waistband and the cuffs. You leaned into his side as he walked you to the dining table. He sat you down and put your napkin in your lap, then giving you a kiss on top of the head.

You ate, wondering if anyone else knew. Could they hear the pad? Would they care if they did? You poked at your rice, thoughts drifting. It took a nudge from one of them to bring you back down to earth. You’d blink, trying to focus again, go back to eating. When you looked up, you saw Izuku watching you thoughtfully.

“Come on,” he took your elbow, lifting you out of your chair. You stumbled, following along behind him. He brought you back to the room he shared with Katsuki, pulling back the blankets and inviting you in.

“I have to pee first,” you blurted. “And we can’t sleep here. Or I can’t.”

“Why not?” he raised an eyebrow.

“Because then Kacchan will know that… I needed a bed pad and I wet the bed, and I don’t–.” you shook your head.

“He won’t know. I’m between the two of you, and even if he did know, he wouldn’t care.” he kissed your cheek.
“We all just want you to be healthy and safe. Maybe you’re working too hard. Maybe you should take a few days off.”

“No,” you said flatly. “I don’t wanna talk about it anymore, ‘Zuku.”

“Okay, okay. Sorry I pushed, princess. Just relax and watch television.” you were still tired, and it wasn’t any kind of surprise that you were asleep in his arms quickly. He looked at you, sleeping, lips parted. He peeled back the blankets and eased off the pants you were wearing. He took another glance at your skin, frowning at how sore it was.

With any luck, this was going to help.

Chapter Text

“Stop,” you grumbled, trying to roll over and go back to sleep.

“Sorry, honey, I don’t wanna leave you in wet panties. And the pad is all wet, too. Don’t you want to be dry and comfy, honey?”

“Yes,” you mumbled, letting yourself fall back asleep. Your underwear was eased down, the pad rolled away. A fresh one was rolled out, fresh underwear with a dry pad put on. You didn’t move, out like a light. You did roll towards another body, knowing this wasn’t Izuku. This was someone warmer, with shoulders that were wider, who let you snuggle up right against his ribs.

“Shh,” a hand rubbing your back. “You did so good with that. Didn’t fuss or nothin’.” a voice praised. You didn’t even wake up when you were scooped up and carried to the kitchen. You only woke up when you were put down in your seat.

“Good morning, princess.” Hanta chuckled. You opened blurry eyes to glare at him. You yawned and stretched. A plate was put down, and you began eating without thinking. It wasn’t unusual for you to be rocking the Winnie the Pooh look. As you began to wake up, you squeaked. Could any of them see the pad? Did it add bulk to you? Well, Izuku’s shirt was so long, but…

“Calm down,” Katsuki said out of the corner of his mouth. “You’re fine, sweetie.”

You were not fine. You realized that you had wet the bed. Again! Only this time it wasn’t even your bed. It was Kacchan and Izuku’s. Oh, they had to hate you. They had to think you were disgusting. Your lower lip quivered.

“What’s wrong?” Eijirou looked up with a frown. “What happened?”

You couldn’t speak, face in your hands.

“Our girl has had a rough week or so.” Izuku said softly. You let out a whining sound, shaking your head.

“What’s wrong? Is it work?” Denki leaned towards you. “Because we’ve all kept telling you to leave that horrible job. We make enough. You could just stay home and read, or–.” you wailed, uncertain why it was so upsetting for him to say that.

“No, Denki, it isn’t work. Although I’m sure that’s part of it.” Izuku came to stand behind you, squeezing your shoulder.
“You should let everyone know. We just wanna help you out. No one here is going to laugh at you, or say something bad.”

“I don’t want to.” you shook your head.

“This sounds serious.” Eijirou put his fork down, a sure sign that he felt a certain way about whatever was happening.
“What’s wrong with our girl?”

“She’s been having some…bladder problems.”

“Oh!” Denki’s eyes went wide. “Like the other day when you wet your pants in the hallway?”

“It was an accident!” your voice was getting higher. “I don’t know why I wet the bed, maybe I was just tired. I’m sorry, I’m sorry!”

“Hey, hey, hey.” Izuku wrapped his arms around you, pulling you against him. “No one is mad. I understand. I’m not telling them to make fun of you. Just so they know so they can help us.”

“I think,” Katsuki didn’t look up. “You need to wear your pads all the time, not just at night. Just in case.”

“I don’t piss my pants.”

“You do.” Izuku kissed the side of your head. “And we’re going to get to the bottom of it and find out what’s wrong.”

This was too humiliating, you thought. Why wasn’t the floor opening up to swallow you whole? Why didn’t a bolt of lightning come to zap you? Why didn’t anything happen to make any of this stop? What were you being punished for.

“It does sound like a good idea.” Eijirou nodded. “Come on, princess. Why don’t we go get dressed for the day.”

“I can get dressed by myself!” you bolted towards your room. You went in and slammed the door, collapsing on your bed. You really, really didn’t like that any of this was happening, and you didn’t understand why it was happening.

**

You sat on the couch, scowling. Arms crossed over your chest. There was no way that you were going to be able to go to work. Not with pants wetting problems. Even though, ostensibly, the pad should be enough. Still, if you flooded it while asleep, after already going pee, you couldn’t act like it wasn’t even a possibility.

You had kept the pad on, but put on a pair of pants over your underwear. You weren’t going to give anyone a reason to make fun of you!

“You look tired,” Hanta dropped onto the couch looking at you.

“Tired of all the bullshit.” you grumbled.

“Izuku said you didn’t sleep well.” he wrapped an arm around your shoulders, drawing you into him. You huffed, turning to hide your face in his chest. Hanta kissed the top of your head, rubbing between your shoulder blades.
“It’s making you cranky.”

“I am not cranky.” you insisted.

“You are, too!” he laughed. “Sitting here looking mean, pouting.”

“I was not pouting!”

“Yes you were!” he laughed again. “Lower lip out and everything.” he shook his head. “But it’s okay, you’re just tired.”

Well, you were tired. Hanta stretched out on the couch. You’d bought a huge couch, since so many of them were tall and bulky. He held out his empty arms. The couch was big enough for you to lay down.

“We can take a nap.” he played with your hair. “You’ll feel better after some rest, won’t you?”

You harrumphed, snuggling into him. Hanta grabbed a throw blanket to wrap around you. Slow, steady breathing, his heart beating a gentle lullaby. You were asleep before you knew it.

“Even napping?” Denki’s voice filtered through your dreams. “Maybe we should go to the doctor.”

“Izuku has some more ideas,” someone was stroking your hair. “But she had her pad in, so it’s fine.”

“Hold her still, I’ll get her a dry one.”

“No!” you yelped, bolting to sit upright. “I’m sorry, Hanta, I am. Don’t touch me, Denki.” you scrambled off the couch, hurrying for the ensuite in Izuku and Katsuki’s room. That was where the pads had been left. You snatched them and rushed to the bathroom you typically used.

You didn’t want Hanta and Denki seeing them, being reminded. But you really didn’t want them to grab them and try and change it for you. You sat down, hands shaking as you took off the soiled one to pitch.

You’d feel better after a shower, you decided. You set the water to hot, wanting to boil your flesh. It was the only way that you were going to feel clean, you decided. You almost missed the door opening. You poked your head out, seeing Denki poking in.

“Are you okay, sweetie?”

“I’m gonna start locking the door.” you threatened. “And then you’re gonna stand in the hall and piss your pants, and we’ll all fuss over you and we’ll make you feel bad and we’ll never let you forget it!”

You had meant it to be a tease. But once you started, you couldn’t stop. Your voice cracked and you felt yourself shake. Denki made a sympathetic sound and stepped into the bathroom. He bustled about to get you a towel, holding it open to entice you out. You stepped out, letting him wrap you up.

“Don’t you know how much we love you, baby?” he hummed, rubbing you dry. “We only want you to be healthy.” he kissed your cheeks.
“Let’s go get clean clothes, and then we’ll eat lunch and watch whatever you want on television, okay?”

“Okay,” you felt like you were being mollified, like a child. But you couldn’t pretend you didn’t like it at least a little.

You returned to your own bed, with the disposable pads Izuku had brought for you. He kept refilling the little mini backpack, keeping you in the incontinence pads as well. You could pretend they were just like period pads, you assured yourself. And honestly, the bed wetting tapered off. Maybe the guys had been right, you thought. Maybe you were just stressed.

You were able to stop wearing the pads, go back to your regular underwear. You did keep the disposable blue backed one on your bed. Just until you could be confident again, you thought. Just in case.

But, you thought, you did kind of miss sleeping with one of them. You knew that any of them would have welcomed you. Katsuki and Izuku would have cuddled you, Denki and Hanta always had space for you, and Eijirou loved to cuddle.

It was safer in your own bed. After all, when you did have a little accident here and there, you had the pad. You could sweep it away in the trash, your bedroom trash. And no one ever checked there. You were safe.

When your door opened late at night, you didn’t wake. When someone pulled back your blanket and lifted you up, leaving the wet bed pad down, you were still asleep. Then someone kissed your lips, such a gentle motion that you leaned into. He laughed, the quietest sound.

“Come on, babes.” he carried you, laying you down in his own bed. There was a rustling and you yawned, stirring a little. Someone stroked your forehead, obviously hoping to keep you asleep. You woke though, looking around.

“Wha’?”

“You’re wet, that’s all.”

“Not again,” you groaned. “I’ll get it, I’ll get it.” you went to move. Izuku held your hips down.

“I will figure it out.” he assured you. He was easing down your underwear as he spoke. You were reminded of the fact that he was such a good hero. He was very talented at getting people to do things when they were scared or resistant.
“Your skin,”

“I’m fine,” you shook your head.

“Obviously not,” he parted your thighs, examining your groin. You tried to shove at him until another set of hands took yours, holding them gently.
“You’re all sore and chafed.”

“Because I wore the wrong underwear.” you shot back. Izuku sighed. He stood up and left the room, coming back with that zippered bag. Or maybe this one was bigger? You couldn’t tell. He unzipped it and pulled out a tube.

“This will help,” he hummed. He uncapped the tube and a thick white cream came out on his finger. Without a glance at you, he was rubbing it into the sore places. You groaned, closing your eyes. You didn’t open them again until you felt something being pulled up your legs.

“What is that!?” you demanded, sitting up halfway.

“It’s just like the pad.” he soothed, pulling it up the rest of the way. “But this means you won’t have to use one of the big pads in bed. See? Isn’t that much more comfy?”

“It’s a diaper!” you squeaked.

“But honey, it’s much more comfortable. And this way you won’t have to have the wet pad rub up on you, and you aren’t going to get any of the rash cream on your underwear. See? Isn’t it much better?”

“No,” you shook your head. “This is too much!”

“It is not.” he shook his head. “Just lay down here, and you and I will snuggle after my shower. Kacchan, will you–?”

“Shut up.” Katsuki huffed. He dragged you towards him. “I don’t need you chattering at me.”

Izuku headed to their bathroom. You let your face hide in Katsuki’s neck. He wrapped you in his arms. You exhaled, trying to calm down. You were so tired, so fuzzy and confused. And Katsuki was so warm and strong.

You were nearly asleep when Izuku climbed into bed, spooning up behind you. You could all three sleep in one pile, happy and safe, warm and comfortable. You were especially comfortable when you felt an arm from each of them rest around your waist.

***

“You wanna get in the shower?” Katsuki’s voice mumbled to you in the morning. You stirred and nodded. A shower sounded nice. He pulled back the blankets. You climbed out of bed, feeling something hugging you. Confused, you tugged up your shirt and gasped.

“What the fuck?”

“Calm down,” Katsuki snapped. “Deku was just trying to make you comfortable. You’ve got a rash. I wanna take a look in the shower.”

“I don’t want to.”

“Don’t act like a baby unless you want to be treated like a baby.” he warned.

“He put me in a diaper! Does it get much worse?”

“We can find out.” he was bluffing, you knew that. But you still zipped your lip and followed him to the ensuite. He started the water while you stripped. You quickly shimmied out of the diaper, ignoring that it was actually wet.
“Spread ‘em.”

“What?” you glared.

“I said I was checking your rash.” he pinched your thigh until you spread your legs, face hot. He knelt down, hair still messy from sleep. He examined your skin. You hissed when he reached a certain tender area.
“You’re gonna need more cream.”

“I will deal with it.” you said through clenched teeth. Katsuki didn’t say anything else but stepped into the water. You grabbed his special sponge, with the texture, and added his favorite body wash. He loved when you washed his back, saying you were the only one who put the right amount of pressure to really help him exfoliate. Katsuki was prone to sweating at work, and he hated the sticky feeling after being too sweaty.

When that was done, Katsuki steered you under the water. He made you put your head back, pouring a little of his fancy shampoo in his palm to wash your hair. He had been
after you for ages to let him fix your hair care routine. You told him you didn’t care, continuing to use cheap shampoo.

Actually, you would have been willing to let him change things up. But you liked getting under his skin more, and you liked the way that he scrubbed at your scalp now. He mumbled about product build up and follicles. You closed your eyes, feeling him wash away some of the stress you had.

“Let the conditioner sit.” he grumbled after he applied it. He switched spots with you, scrubbing down his front. You looked at him thoughtfully until he glanced at you with a quirked brow.

“Did you ever think that we live a kind of weird life?”

“Absolutely, but you’re all a bunch of freaks, so who cares?”

“Katsuki!” you scolded. “I mean…” you trailed off. You knew he and Izuku were in a relationship, the same with Hanta and Denki. But you did sometimes supply things like..blow jobs and hand jobs and cuddles and got fingered and well…
“The other stuff.”

“I think,” he said slowly. “That whatever we do as consenting adults in our own home is our business. Did someone say something to you?” he demanded. You shook your head, grabbing a washcloth to clean yourself with. The two of you remained quiet for a while. He steered you back to rinse your hair. He cupped your face in his palms and kissed you gently.

“Thank you, Kacchan.” you whispered.

“Let’s get dried off and eat breakfast.”

Chapter Text

“I can put the cream on by myself!” you snapped when Hanta approached you with the same tube Izuku had used last night. “Just give it here.”

“No way,” he shook his head. “‘Zuku told us where it is, and Katsuki said it’s pretty sore. You can’t see well enough to reach there.”

“I said no,” you held out your hand. “Give it.”

“Babes,” he began.

“I don’t care! I said no. It’s my body and my life.”

“Hey,” Eijirou came into the living room with a frown. “There’s no reason to get loud. We’re trying to help you.”

“I didn’t ask and I don’t want it.” tears stung your eyes, and you felt ashamed of yourself, swiping at them.

“Aww, hon, it’s okay.” Eijirou was never able to stand to see you cry. “Come here.” he wrapped you in a hug.
“It’s nothing to cry about. You don’t need to be embarrassed. We love you so much we want to take care of you.”

“But I can take care of myself.” you insisted.

“You don’t need to.” Eijirou said gently, tucking your hair behind your ears. “Let Hanta do this for you, and then you and I can go to my room and play Mario Party?” he dangled it in front of you like a prize. You sniffled and nodded, feeling like you were being bribed.
“Okay, good! Good girl. Here,” he suddenly pulled your pants down.

“Hey!”

“Just be still.” Hanta already had the cream on his fingers, spreading it on the sore places. You winced and Eijirou rubbed your back to soothe you.
“You do not want this all over your panties, do you?”

“So I don’t need any. Can we just, for the love of God, let all this go and move on with our lives?”

“Ooooh no ya don’t.” Katsuki said on his way to work. He acted like you with your pants down in the living room was no big deal.
“You are not gonna wear nothing on my nice furniture and piss on it. You wear one of those pads the nerd got you.”

You gasped, tears filling your eyes again. You broke away from Eijirou, who was glaring so hard at the blond, he didn’t seem to be able to snag you. You kicked off your pants and raced for your room, slamming the door.

“Really, Kats?” Eijirou was sighing. “Was that necessary?”

“Do you wanna scrub piss out of the couch?”

You threw yourself on the bed, sobbing, head folded into your arms. It was bad enough that the whole house knew about it, and even worse that they seemed to have opinions about it. Well, you decided. You weren’t going to stick around here and worry about it.

It was hours before your shift, but you grabbed a pair of underwear. An old pair, but who needed to know? You paused and scowled, grabbing one of the incontinence pads and slapping it in. You snuffled to yourself, pulling on your uniform pants and shirt. You snatched your tote bag, stuffing in a few more pads. You arranged your hair with your fingers before giving up and tying it out of your face.

“There you are,” Eijirou looked relieved when you stalked towards the door. “Wait, why are you dressed like that? Where are you going? I thought we’d play Mario Party.”

“Work, I’m going to work.” you snarled. “Where I can be in peace and no one is pestering me about my fucking underwear.”

“Princess,” Hanta sounded reproachful. “I know what Kats said wasn’t very nice. But you are helping you. Are you sure you want to go to work today?” you coaxed. “What if you–well, what if you have an accident?”

“I’m wearing those stupid damn pads. No one needs to worry about it.”

“But we’ll worry about it.” he said. “Because it’s obviously upsetting to you.”

“It’s upsetting because no one will leave me the hell alone!” you shouted. “I don’t need help.” your hands were shaking as you went for your shoes.

“All right,” Eijirou hauled himself off the couch and came to you, grabbing your arm just above the elbow. “That’s enough.”

“Let go of me, I don’t want you!” you tried to shake him off. He bent and picked you up, reminding you once again how easily a pro could do these things. He tossed you over his shoulder and marched to the table, plopping you in a chair.
“What the fuck is this?”

“Hey,” he caught your chin, gently turning you to face him. “I hear that you’re upset and embarrassed. That’s fine. What is not fine is you screaming at us or using harsh language.” he put his hands on your shoulders and gave a squeeze.
“Sit here and calm yourself down. And then we’ll have a talk about it.”

“I don’t need a talk. I have to go to work.”

“No, you don’t.” he shook his head. “If one of us calls you in—.”

“I don’t want special treatment! It’s my job and I want to, and I’m leaving you can’t make me stay.” you shoved away from the table.

“I am not letting you go out all worked up, you aren’t focusing and you could get hurt somewhere.” he pushed the chair back in.
“We will talk as soon as you settle down and we’ll decide about work. So maybe work on calming down.” he bent to kiss your head, ignoring the frustrated sound you made.

You put your head down on the table, pillowed by your arms. You wanted to scream, thunder out of the house. They’d catch you though, you thought bitterly. They were always faster than you, stronger than you.

You were so sick of crying, you thought as you sniffled. You’d cried more in the past few days than you had in months. You felt so helpless, you thought. Like you were just in the way, like you were an inconvenience.

You weren’t sure how long you sat until you felt hands rubbing your shoulders. When you lifted your head up, you realized it was Hanta. You leaned back, desperate for some affection. He bent down to wrap you in a hug.

“There’s my princess.” he cooed in your ear. “You’re okay. I know, it’s a lot.” he rocked a bit on his feet, kissing your head.
“Do you feel a little calmer?” you nodded unhappily.

“Come here so we can talk.” Eijirou patted the couch. You got up and dragged yourself over.

“I’m sorry I yelled and was mean to you.” you said, looking at your hands.

“I know,” he smiled. “And you’re forgiven. But I still don’t think you should go to work. You’re really upset.”

“I’ll get fired.”

“No you won’t.” Hanta jumped in. “And even if you did, so what? There are other jobs, princess.”

“But it looks bad—.”

“Not to us.” Eijiro cut you off gently. “You can afford some time off. Maybe it’s what you need. Now, go ahead and get changed. Into something comfy. You promised me a round of Mario Party, and I am gonna win.”

You rolled your eyes and trotted off, changing into a more comfortable pair of clothes. You were ready to head out when Hanta tapped and poked his head in.

“I’m not gonna say in front of Eiji… but I think you’d feel more comfy in one of the other things Izuku brought you.”

“No!” you shook your head.

“Okay, sh, it’s okay,” he stepped in, closing the door behind him. “It’s only because those pads rub at the same places you’re sore, okay? Not because you need it. I don’t want it to hurt more.”

Chapter Text

Hanta did have a point. You put on the stupid diaper and wore your baggiest pair of sweats. The adult diapers didn’t puff out or add bulk to you, not really. They could have been normal underwear. Still, you grabbed one of Eijirou’s old hoodies, knowing it would cover anything else.

You went to Eijirou’s room, where he sat on the floor, back against his bed. You sat next to him, taking the Switch controller as he brought up the game. He’d brought in a plethora of snacks, the way he always did for these gaming sessions.

It was a fun hour and a half. Eijirou favored salty snacks, like pretzels and popcorn and chips. So of course, you had to keep sipping from the giant water bottle that he’d brought it. Your mouth would get so dry! You didn’t need to think about it, though. There were tense moments, him being Monty Mole and you happy as Rosalina. You bantered back and forth, both of you wriggling and leaning in place as you played.

Towards the final round, Eijirou hit pause and looked at you expectantly. You stared back at him blankly. He clearly thought you needed to do something, or was waiting for something. He cleared his throat and you shrugged.

“Go potty.” he said.

“Wow! Okay!” you tossed the controller. “Why the hell would you say it like that?”

“You need to pee.” he kept his calm demeanor. You seethed, getting more upset that he wasn’t returning your own temper to you.

“I am an adult, and I can go pee when I need to.”

“Oh?” he raised an eyebrow. “So you didn’t have an accident when napping with Hanta just a little bit ago? And you didn’t cry and have a whole meltdown?”

“That–that was different.” you felt desperate. And now that he mentioned it, you did have to pee. You didn’t know how you didn’t realize it before. Your bladder was aching, and it was going to be hard for you to stand up.
“That was an accident.”

“And it would be if you wet yourself here.” he agreed. “So go potty.”

“Can you at least call it something else?” you whined, standing up. You winced, crossing your legs as you stood.

Eijirou had the grace not to say he told you so. He stood up and stretched himself. You walked slowly, carefully to the bathroom. He followed you, and your face burned. You wanted to scream at him to go away, but you got the feeling that getting worked up would not do your case any favors. Not in staying or dry or proving that you weren’t a child. To your shock, he stepped into the bathroom with you.

“Go away!”

“I’m putting more rash cream on you.” he shook his head. You glared and mumbled some very uncharitable things under your breath. To your relief, the diaper was dry. But he was puttering around the sink, very pointedly ignoring you.

“I can’t go when you’re right there.” you sighed. Eijirou smiled and tilted his head, turning on the sink. The sound of rushing water was enough, and you were peeing. At least it was covered up by the sound of the water. Eijirou grabbed the cream tube and sat on the edge of the tub. He waited for you to finish, flush, and wash your hands.

“Come here.”

“I don’t need it. I feel much better.”

“It takes more than two applications.” he shook his head, gently grabbing your hips and steering you to stand between his knees. He eased down your sweats and diaper, grabbed his hoodie and held it up.
“Hold that for me, please.”

“Well how would you know?”

“Says so on the box.” he didn’t look at you as he nudged your legs apart. He let out a whistle at the rash.
“You really need to be more careful, baby. You could get sick, you know?” he applied a generous amount of cream and pulled up your diaper.

“Whatever,” you muttered, reaching for your sweats.

“Why bother with them?” he stopped you. “It’s only me and Hanta, and we already know. And the hoodie covers you.”

“Hell no,” you yanked your pants up. “Wash your hands so we can keep playing Mario Party.” you demanded, turning and going to his room so he wouldn’t see the look on your face. Eijirou shrugged and went to the sink.

He won at the game, and you gave him a fake pout and handed the control over. He turned off the system and hopped onto the bed, patting the space next to him. He went to sit next to him. He leaned against you, his head on your shoulder.

“I love you,” he said gently. Whenever he said it, he said it with such sincerity it always made your heart squeeze. You whimpered and turned to press your cheek to his head. Days when he was home, he left his hair down.
“I think we should talk to ‘Zuku when he comes home.”

“‘Bout what?” you asked in a sulky voice, like you didn’t know.

“I think he’s got some ideas. And it would be nice to hear him out.” you opened your mouth, but Eijiro reached up and pressed a finger to your lips. He stroked your cheek, the way he always did when cuddling. It immediately set you into a calmer place.
“There’s my girl.”

“Just because I listen to him doesn’t mean I agree with him, or that I’m agreeing to what he says.”

“Of course,” he agreed.

“So if I say no to any of it, the answer is no.”

“Naturally.” his arm wrapped around your waist.

“So no one is gonna pressure me?”

“No,” he agreed. You sighed and relaxed. Eijirou kissed your cheek and checked his watch. “Come on, Izuku and Katsuki and Denks will be home soon.” You nodded and got off his bed to head to the living room, still unenthused about what was to come.

Chapter Text

“Oh sweetheart, you had another accident?” Izuku gave you a sympathetic look when Hanta told him what had happened that morning. You groaned and refused to look him in the eye. “And Eiji says that rash is looking really rough.”

“It’s fine,” you huffed.

“It’s not,” he knelt down in front of you on the couch, his hands on your thighs so you’d have to look at him. “I’ve been thinking…”

“Must have been painful for you, idiot.” Katsuki scoffed. Izuku ignored him, his thumbs rubbing small circles in your skin.

“I think a lot of this is stress.”

“Yeah, I’m stressed out because everyone keeps mentioning that I wet myself.”

“Well, okay, that’s fair.” he allowed. “But I think it’s everything else. Your job you keep working yourself to death in. You don’t drink right, you don’t eat right. Making all these decisions. You drink way too much caffeine, you know that.” well, he had a point there. You did sling back energy sodas like they were going out of style.

“So what do I do?”

“I think it would help if you let us make choices for you. I think you just need a break from everything.”

“What would that look like?”

“Let us make decisions for you.” Hanta came to sit next to you, hand on your back. You looked at him, confused.
“We’ll decide when you get up. When you go to bed. What to eat. What to wear. I think if we let your mind blank out, you’ll feel better.”

“But I don’t feel bad now.” you insisted. This was so confusing, this was so much at once. Katsuki pushed Izuku and Hanta to the side. He swept you up and sat down with you in his lap.

“Because it’s all too much for your tiny brain, isn’t it?” he teased. You whined and shoved at him. “Sorry, baby, I’m just yanking your chain.”

“I don’t want to.” you mumbled.

“It’s a lot to take in.” he agreed. “I think if you just gave it a try, you’d like it. You’d feel better. And it doesn’t have to be forever.” he coaxed. You pressed your forehead to his collarbone. One of the things about having such big roommates who were your quasi lovers was that they provided ample space for you to hide in.

“It’s only because we care so much about you.” Denki sounded desperate. “We want whats best for you.”

“I’m an adult.” you said from Katsuki’s chest.

“We know that. It was never a question of that.” Katsuki rubbed your back.

“Will you just try?” Izuku asked hopefully. You gave a small, tiny nod. Katsuki gave you a squeeze.

“You’re such a good girl,” he whispered in your ear. “You’re going to feel so much better.” his hand went to your hair, fingers rubbing your scalp. You relaxed into him, rubbing your face against his neck.

“All right then,” Izuku sat back, looking relieved. “Kacchan? I think it’s your turn to make supper.”

“So?” he scowled. “I’m getting a snuggle. You’re just jealous.”

“I can help.” you offered.

“Nope,” Eijirou said brightly. “That’s not your responsibility.”

“No?” you pulled away, confused. You always helped, you cleared and loaded the dishwasher. You were a functioning member of society. Eijirou beckoned to you and you slid off Katsuki’s lap, hearing him mumble under his breath as he got up to go and start cooking. Eijirou plopped down with you on the floor, his back against the sofa with you in his lap.

He grabbed the remote and flipped to a cartoon. You raised an eyebrow and he shrugged with an easy smile.

“Cartoons aren’t just for kids, you know. Animation is an art form.” well, he had you there. You settled back to watch the show, something about kids on summer vacation at their uncle’s house with spooky events. You were quiet in Eiji’s lap throughout the show, becoming engrossed.

“Come eat,” Hanta finally tapped his shoulder. Eiji set you on your feet, patting your bottom. You rolled your eyes and went to eat supper. A plate was made for you and set down, when you’d normally be making your plate yourself. There was a helping of rice, steamed veggies, and chicken.

“Thank you,” you said as a glass of water was placed down too. You ate your rice and chicken and looked at the veggies. You didn’t care for the peas, you thought. You carefully picked them out, setting them to the side.

Your water was finished, and you went to stand. Katsuki’s hand shot out and gripped your wrist.

“Sit down and finish your supper.”

“I did?” you felt confused, trying to shake him off.

“If you don’t finish, you’re going to bed early.”

“Stop that!” you demanded.

“This is what you agreed to.” Izuku didn’t look up from his own dinner. Your jaw dropped. You looked towards the other three, hoping for some back up. They carefully avoided your eye, scraping their own plates clean.

“There are two bites of peas on your plate.” Katsuki gave your wrist a little squeeze. “I know you don’t like it, so I worked to make sure you didn’t have that much. Sit down and eat ‘em, brat.”

“I am not a brat.” you insisted.

“You’re acting like one and I don’t like it.”

“Go ahead and eat,” Denki said. “And then you and I can hang out in my room.” he offered. You grumbled and plopped back down, grabbing your fork and eating the peas with exaggerated motions. You could tell Katsuki didn’t like your attitude, but there wasn’t much he could say or do about it.

Denki grabbed you hand to pull you along. You went to the room he shared with Hanta and made to climb onto the bed. He stopped you with a hand on your shoulder.

“Should we take a potty break first?”

“I know when I need to pee.”

“Isn’t that sort of the issue?” he shrugged. You glared and marched to the bathroom. Denki waited for you outside with a smile, ready to take you back to his room.
“Aww, cheer up, honey.”

“Bite me,”

“Well, that’s not very nice.” he frowned. “Are you sleepy or something?”

“No! I’m just sick of everyone treating me like that.”

“But you agreed to it. Remember?” he sat on his bed and reached for the remote. “Let’s watch a movie and we can play Uno.” you nodded, letting him click on the movie and then deal the cards.

It was easy for you to forget as you played. You and Denki took Uno very seriously, and were famous for getting loud while playing. You had won three rounds when the door opened.

“Having fun?” Izuku asked warmly. You nodded, giving him a smile. “It’s about bedtime. You need rest.” you sighed and put down your cards. You could have fought, you could have kicked and screamed. But you did agree to this.

You trailed after Izuku to your room, where he opened your dresser and pulled out some pajamas. You blushed, thinking that you could have done that yourself. He sat on your bed, pulling you to stand between his knees.

“Hmm, you’re dry.” he noted. “But let’s do a layer of rash cream, okay? It’s been awhile since you had some. Do you need to go pee?”

“No,” you snapped. Izuku ignored it and undressed you, tossing your clothes in the hamper. He yanked off your diaper, and you were grateful that adult diapers were closer to pull ups. He rubbed the rash cream on you and held open another. You didn’t meet his eye and you stepped in and pulled it up. You let him dress you, give you a peck on the cheek.

“Brush your teeth and I’ll tuck you in.”

“Don’t need that,” you shuffled off to brush your teeth and wash your face. Izuku was still waiting for you in your room. And like a little child, he did pull back the blankets and gesture for you to lay down. You crawled in, letting him pull the blankets around you and smoothed your hair.

“Good night, love.”

“Good night,” you said softly. He left the room, turning out your light and closing the door most of the way. You yawned and rearranged your pillows. Maybe they had a point and you did need more rest.

Well, you thought, you were willing to entertain them for a few days. And then you could point out everything was fine and return to business as usual.

***

You shivered, scrambling for your blanket. It took you a moment to realize that you weren’t wearing your bottoms, and the blanket had been moved.

“Sorry, hon,” Eiji said softly. “I was hoping you wouldn’t wake up. I’m going as fast as I can.”

“Don’t,” you tried to shake him off. He held your legs down firmly.

“Be still, please.” he said gently, but firmly. “I’m almost done.”

“It’s cold,”

“Your room is chilly.” he agreed. Something was being slipped up your legs. “Wanna sleep with me?”

You nodded, feeling him lift you up bridal style, leaving your bottoms in your bed. He was warm anyway, and let you cuddle right into him. He chuckled a bit as he carried you through the dark, quiet house to his room.

You were laid so carefully in his bed. You cracked your eyes open, waiting for him to lay himself down. As soon as he was comfortable, you squirmed to lay on his chest, feeling his arm wrap around you. One of your hands pressed against his chest. His hand came to lay on top of it, ensuring that you were close to him. Exactly how you wanted to be.

Chapter Text

“Gotta go pee?” Denki asked as he pulled off your wet diaper. You shook your head, rubbing at your eyes. Everyone had figured out that it was easier to change you before you really awake and could fight about it. He wiped you clean with a warm cloth.

“Carry me.” you grumbled as you felt rash cream being rubbed delicately on you.

“Rash is finally all cleared up.” he noted. He picked you up, feeling you wrap your legs around him. “Good morning, princess.”

“If the rash is gone, can I wear regular undies?”

“I don’t think so.” he noted, going to his dresser and grabbing something out of a drawer. “We’ll talk to Izuku.” he carried you to the kitchen, setting you down with a kiss before a fresh plate of breakfast was offered.

“The rash is gone?” Izuku sounded pleased. “That’s great.”

“So I can go back to my real underwear.” you said it like a statement, not a question. Izuku tilted his head to the side.

“No,”

“What? Why?” you whined.

“Because you’re still wetting yourself, babes. And now that we’ve got your skin better, we can focus on other things.” instead of a cup of coffee or tea, you were presented with a large glass of water. You frowned.

“Can I have some tea?”

“No,” Katsuki drank from his own cup. “Get your water down.”

“But why?” you asked again.

“Because,” Izuku said patiently. “The caffeine could be irritating your bladder and making things worse. We’re gonna have to flush you out.” he watched you sip. You picked at breakfast, and went to rise.

“Sit,” Hanta pointed to your chair. You scowled.

“I’m all done.”

“No, you’re not. Sit down and finish your eggs.” he was finishing his plate. You looked around, seeing if there was anyone who would have stood up for you. But everyone else was carefully looking down at their food.

“I don’t want to.”

“You don’t make the rules.” Eijiro said lightly. You opened your mouth to protest, and Eijiro was scooting to sit next to you. He grabbed your fork and made a bite of eggs and bacon. He held it towards your lips, watching as you took a bite.
“See? Breakfast is good.” he continued to construct every bite before feeding you. It made you feel strange, you marveled. There was a fuzziness that was eating at the edges of your mind. All you could focus on was the food being pressed into your mouth.

“That’s a good girl,” Izuku praised as he walked by. Eijiro was holding the glass to your mouth, helping you drink it down.
“There you go. I gotta get ready for work.”

“You get to spend the day with Hanta and Denki.” Eijiro smiled as the plate was emptied.

“Yup!” Denki stood up. “Let’s get out of jammies, princess.”

Feeling like you were in a trance, you followed him to the living room. You were malleable as he sat on the couch, stripping you out of your pajamas. He had chosen a romper for you today, one that buttoned at the back of your neck with impractical little heart shaped buttons. It was impossible for you to unbutton on your own.

“So cute!” Denki beamed at you as adjusted the romper. It was pink, decorated with hearts. There were ruffles on the butt. Even in the adult diapers which were pretty flat, the bottom was puffy.
“What do you wanna do?”

“Turn on a show for her and leave her with the color books we got.” Hanta said. “And then come and get busy. You’ve got chores to do.”

Denki rolled his eyes and flipped on an animated show. You never had anything against it. He watched your eye get caught by the bright characters on screen, patted your head and dropped the adult coloring books and colored pencils down.

You watched the television show and colored a little bit, a picture of flowers. Hanta or Denki would poke their heads in every so often, each time presenting you with a water bottle. At first, you had scowled.

“I can use a regular glass.”

“I know,” Hanta agreed. “But this won’t spill, and you do have to drink a lot. Remember? Izuku said we need to flush you out.” the water bottle had cartoon characters all over it. The straw top flipped up. It was different from the metal water bottle you had, covered in stickers.

You kept a steady stream of sipping. It wasn’t until your bladder was almost too full that you realized you had a problem. You gasped, pressing your thighs together.

“Denki?” you called. You got up and took painful steps to the kitchen. He would undo the romper and you could go pee. “Hanta?” and then you remembered that Hanta was doing some paperwork at his desk, and he wore headphones all the time.
“Denki!” you shouted. You couldn’t think where else he’d be. You couldn’t walk towards the office, you’d never make it, you thought. You crossed your legs where you stood, bouncing slightly.

Your hands reached to the back of your neck. Your fingers pinched at the stupid buttons. You had to get this thing off! You had never had an accident where you could feel it. Certainly not like this. Your hands were shaking, trying hard to focus and get it undone.

“Hey, what’s wrong?” the back door swung open and Denki was standing there, having taken the trash out. You whined, feeling piss dribbling out. He frowned and took a few steps towards you.

“I’m sorry, I am!” your voice was raised, feeling hysterical. “You can’t put me in things like this!”

“Oh, baby,” Denki hurried over. “Are you having an accident? It’s okay, it’s okay. That’s what the diaper is there for.” you wound your arms around his neck, burying your face in his chest. He rubbed your back, the hissing sound filling the kitchen.

“I tried, I really did. Denki!”

“Shh, I know. It was the buttons, wasn’t it?” there was another set of footsteps and you wanted to scream, feeling your face go hot.

“What’s wrong?” Hanta sounded immediately concerned.

“We’re having an accident, Han.” Denki murmured. “She’s really upset. Can you–?”

“I got it,” he turned and walked off. You whined, feeling the last dribbles of piss falling into the diaper. You wondered if your bottom looked swollen now. Denki was undoing the buttons on your romper. Just as Hanta came back, he was pulling it off your body.

You peeked at Hanta, standing there with a packet of wipes and something else? It was pink, you noticed. Pink and it had little flowers on it. A closer glance made you shout, realizing it was a diaper.

Not like the pull up style adult diapers you had been wearing. Those were plain white. But this? There was no mistaking what else it could be. How did diapers this big even exist? Hanta pulled down your wet diaper.

“No one’s mad.” he said gently. “It was just an accident, wasn’t it? We’ll get you all clean and dry and you’ll feel so much better.” you shivered as the cold wipes went at your skin.

“We need to get a warmer.” Denki noted. He still had his arms around you, keeping you still against him. The diaper was placed between your thighs. One of Denki’s hands went to hold the front up against your belly as Hanta taped you in.

“There we go. Nice and comfy for my baby!” Hanta stood up. “I’ll get a top for her.”

“I need pants.”

“No, you don’t. It’s just me and Hanta, and we already know. This way you won’t have to fight with taking pants off.”

This diaper was much thicker than the last one. You couldn’t bring your thighs together. Denki reached down to pat your bottom and you whined, hearing the crinkle. You wanted to shove away from him, run and hide. But Hanta was back with one of his own shirts. He pulled it down over you. Rubbing your thighs once it was down, he kissed at your neck.

“You look so cute,” he sighed in your ear. “Look at you, pretty pink diaper and everything.”

“I don’t want it!”

“I know, I know,” Denki picked you up. “Let’s have a snuggle on the couch and you can calm down. It wasn’t because you couldn’t get to the big girl potty. The buttons were too little. I’m sorry.” he laid on the couch with you against his chest. He rubbed big circles, feeling the fluttering of your heart.

“I don’t wanna do this anymore.” you mumbled.

“Shh,” he hushed you. “We’ll talk to Izuku when he comes home.” You turned your face towards the television, fingers coming up to pluck at your lips.
“No, keep your fingers away from your mouth, that’s icky, babes.” he reached for your water bottle, tucking the straw in your mouth. You had a few sips and settled in, trying to calm down.

Chapter Text

“What’s wrong?” Izuku asked sweetly as soon as he stepped in. You were still on the couch, curled up with Denki. Your face burned and you pulled at the hem of Hanta’s shirt. Denki hummed and rubbed your back.

“She had an accident.” Denki said softly. “And we were all out of the white diapers so…”

“Oh?” he sounded intrigued. “Show me.”

“No!” you shook your head vigorously.

“I need to see,” Izuku was hanging up his coat. “To understand how they fit.”

“No, because I’m not gonna do it anymore.” Denki was helping you stand up. You refused to look your roommate in the eyes. He slowly, carefully lifted up the shirt you were wearing. He took in the pink diaper around your bottom.

“They fit,” he noted. “You have to make sure the leg cuffs are right though,” he reached and fixed the leg cuffs. “There we go.”

“Take it off.” you demanded.

“But honey, you need it.” he was on his knees, putting his hands on your waist. He gave you a little squeeze and then patted the front of your diaper. You jolted backwards from him.
“Wouldn’t it have been worse to wet your panties?”

“I wouldn’t have because I could have gone straight to the bathroom.”

“I’m not sure about that,” he shook his head.

“Then I want the white ones back.” you crossed your arms.

“No, babes. They were all sold out. Besides, these are so cute!” he beamed at you. You groaned, closing your eyes. The door opened again, Katsuki this time. You went to shove down your shirt. Izuku’s hands kept it up.
“Kacchan? Will you please tell our pretty baby that she looks cute?”

“She always does.” he said without thinking. He gleaned at you and a slow smirk spread across his face.
“What happened, baby? Can’t hold it? Did you pee on yourself?”

“Stop that!” you whined. He laughed and walked over, examining you himself before letting your shirt fall down. He picked you up, giggling as you squirmed in his arms. He gave you a little bounce, relishing in the way your face went hot when your diaper crinkled.

“You do look so cute.” he assured you. “Wanna come and sit in the kitchen while I make supper?”

“No, I wanna be alone.”

“Not a chance.” Katsuki shook his head, putting you in a seat. “You need to be watched. You know that.”

“I’m not a baby!” you pounded your fists on the table. “Will someone fucking listen to me?”

“Enough!” Katsuki pointed a spatula at you. “You’ve been warned about the language.”

“I don’t have to do a damn thing you say.” you shoved away from the table, wondering how indignant you could look in this stupid pink puffy diaper anyway. But you were gonna try.

“No,” Hanta put his hands on your shoulders. “You were told to sit and wait for supper.”

“I don’t care,”

“Fine then,” Hanta was walking you to the living room. You relaxed a bit, until you saw that Izuku was putting a small chair facing the corner. You tried to stop walking, to plant your heels.

“What is this? I don’t wanna sit here!”

“You wouldn’t sit nicely at the table.” Izuku took your elbows and steered you to sit down. “You’ve got five minutes.”

“Until you come back to your senses?” you spat.

“What are we fussing for?” Izuku frowned. “Are you wet? Do you need to go potty?”

“Quit talking to me like that!” you roared. “I’m not fussing, I’m upset.”

“How come?” Eijiro took in the scene.

“Because she’s in time out.” Izuku supplied. “For back talk and using naughty language.”

“I told you not to do that.” Eijiro fixed you with a frown. Was no one on your side? You grunted and plopped in the chair, arms crossed. Everyone ignored you, sitting in the corner. Like a bad girl, you thought.

The thought pricked at you. It made you feel all quivery inside. And weirdly enough, it made you feel scared. If you were a bad girl, no one would want to keep you around. If you were bad, no one would like you. You whimpered, squirming in your seat. If you were bad, you were going to be on your own. Well, maybe that was good? Maybe you’d be able to wear regular underwear and go back to work and–.

“Whoa,” Denki put his hand on your shoulder. You had not realized that you were crying. “What’s with the tears, princess? This was just so you could calm down a little bit, you were getting heated in the kitchen.”

“I’m not a bad girl!” you blurted.

“Of course not,” he soothed. “Did someone say you were?” you shook your head. “Because we all know you’re not a bad girl. You’re a good girl. You’re our good girl.” he wiped at your cheeks.

“Her time is up,” Izuku said softly. Denki nodded and picked you up, carrying you towards the kitchen. You met Katsuki’s eye. He tilted his head to the side, holding out his arms. You reached out to him, grateful when he gave you a hug.

“You’re sorry, aren’t you?” he murmured in your ear. “You’re okay.”

“I’m setting the table,” Hanta called.

“Have Shitty Hair come and get the stuff out of the oven.” Katsuki turned to walk with you out of the kitchen, to the room he shared with Izuku. He sat with you on the bed while you sniffled, still feeling shaking on the inside.

“I am sorry, I am.” you whispered. ‘I’m not bad.”

“No you’re not.” he agreed. The two of you sat for a few minutes until Katsuki decided that you were calm enough. He carried you back out to the kitchen, sitting you in his seat. To your surprise, the table was laid with a selection of finger foods.

“You can feed yourself anything you’d like.” Izuku sounded pleased with the idea. You made yourself a plate, nibbling at things whole they spoke. You zoned out of the conversation. You focused on the cut up veggies on your plate. With two cucumber slices, you began making a face on your plate. The cumbers made the eyes, sliced red peppers were the eyes, and you used carrot coins as the ears. Broccoli made his hair. You giggled.

“Stop playing with your food, my love.” Izuku smiled at your plate. He lifted one of the broccolis to your mouth, watched you chew. When you finished the plate, Eijiro came to get you.

“Let’s take a bubble bath.” he announced. You followed him to the bathroom, standing while he filled the tub for you. You took off your shirt, feeling him reaching for the
tapes of the diaper. “All ready,” he helped you in, watched you sink down.

“Eiji?” you asked quietly.

“Yes, baby?”

“Are you… do you…” he waited patiently. “Aren’t you mad at me?”

“Mad? For what?”

“Wetting my pants and being mean?” you mumbled. He shook his head, leaning in to kiss your forehead.

“Not at all. Relax and enjoy your bath, hon. You need to relax, remember what Izuku said?”

Chapter Text

“I don’t know about you, but I am sick of waking up in the middle of the night. This isn’t helping you rest.” Denki announced.
“But I have an idea, cutie.”

“An idea?” you frowned.

“Yup!” he beckoned to you, leading you to the hall bathroom. “Get in the tub,” he gestured. Confused, you stepped in. He bustled about the bathroom, gathering rash cream, a dress diaper, and a can of powder.

“What’s that?” you pointed to the powder.

“It’ll keep you from getting too rashy, babes.” he gave a little smile, seating himself on the toilet.
“Go ahead.”

“Go ahead and do what?” you blinked.

“Go pee,”

“Huh?” you gaped. “Why?”

“So I know you’re all emptied out before I put you in your night diaper.” he shrugged. “That way I know you’ll stay dry for a little bit and we can both sleep the night through.”

“Or,” you clenched your teeth. “You could get up and let me go pee in the toilet, like a real person. And then we’d all know that I had gone pee.”

“This is easier.” he shook his head. You didn’t think it was. You stood there, staring at him, waiting for him to come to his senses. Denki sat casually, giving you his carefree smile. You whined, shaking your head.

“This is not easier for me.”

“It would be if you got out of your head about it.” he shrugged. “I know you wet yourself. We all know that the princess has a little bladder problem, and we’re not upset about it. We’re trying to help you! That’s the whole point of this exercise, babe. So make a nice wet diaper before bed and I can get you all clean and ready to tuck in.”

“No,” you protested quietly, finding it hard to use your voice.

“Yes,” he leaned forward, elbows on his knees. “You’ve been told you need to do what we say. You don’t make the choices, do you? No, we do. So go pee and we can get ready for bed. Aren’t you tired, love?”

“No!” you stomped your foot, hearing the strange echo it made in the tub. Denki’s eyebrows went up.

“Well, it’s bedtime anyway.” he took on a stern tone. “Go pee.”

“Let me use the toilet, please?” you begged. “Please let me go pee!”

“I’m not stopping you.” he sat back. You looked at him, mouth working. Denki was radiating patience, which was strange from him. You wriggled in the tub, feeling the pressure growing in your belly.
“It’s not good for you to hold it like this.”

“So let me use the toilet! I’m a big girl, I am.” you shouted. Denki shook his head. He knelt down in front of the tub, taking your hands in his.

“You are getting all worked up for nothing. There’s no reason to be upset, princess. You have to pee. I know it and you know it. You’re in a diaper, there won’t be a big mess to clean up. It is bedtime, and I can tell you’re getting tired. Whenever you’re tired, you start getting cranky, and then you get in trouble.”

“Because you treat me like a baby.”

“Because you agreed to this.” he gave your hands a little squeeze. “Close your eyes, pretty girl.” you did so. “Good! Now breathe with me, a few deep breaths.” he took exaggerated breaths, and you copied him.

You did relax a little, feeling the warmth of Denki’s hands on yours. You wanted to be hugged, you thought. You wanted to be held. You wanted him to lay you down in bed and let you go to sleep already.

“Denki,” you whined.

“I know, I know.” he tried to calm you. “Get it over with, love.” and you released your bladder. Relief flooded you, along with shame and the piss filling your diaper. You could feel the material between your thighs swelling as it held all your fluids.
“There you go, oh, what a good girl you are.”

Something about being called a good girl made you melt on the inside. You stood with your legs apart until you were at last done. You could have sagged, feeling empty and strange. But Denki didn’t give you time to think, helping you out of the tub and laying you down on the bathroom floor.

Your head was fuzzy as you felt him taking off your pants. He said nothing about your full diaper, undoing the tapes and using the baby wipes to clean you up. You winced, flinching away from them.

“Shh,” he rubbed your thigh, calming you. “We need to get you a change mat, huh? Can’t be much fun to lay on the floor.” he spread rash cream on you, then patted your leg. “Bottoms up for me.”

You slowly lifted your hips, feeling him slide a fresh diaper down. He gave you a little shake of powder, rubbing it in with his hands. And even though this was a diaper change, your eyes fluttered shut at his touch.

“Oh?” he teased. “Is this really what’s got you all wound up? You grumpy because we haven’t been paying enough attention to you?” you whined, covering your face with your hands, squirming.

Denki taped up the diaper and put your pants on. You blinked, confused as he helped you up and loaded your toothbrush for you. You took it and stared at it, as though you weren’t sure what to do. Denki stood and watched until you put it in your mouth and began to brush your teeth.

“That’s something I’m gonna have to chat with everyone about, love. We haven’t made any kinds of rules or boundaries yet. It’s a conversation for all of us.” on some level, you understood that and even agreed. On another, you were shocked and disgusted with yourself. The thoughts stormed inside you while you rinsed until you turned and held up your arms.

“Carry me,” you demanded, aching for some closeness. Denki laughed softly and picked you up, letting you hook your chin over his shoulder. Denki stood with you for a
moment, rocking a little bit in place.

You were surprised at how much it calmed you down. He carried you to the living room, giving everyone a chance to tell you goodnight. Cheek kisses were exchanged, along with hugs. You were carried to your room then. Denki laid you down and pulled the blankets up.

“It’s too cold in here for you, princess.” he frowned. You shook your head and burrowed down. He sat on the edge of the bed, looking at you.
“Could at least get a bigger bed and we could cuddle.”

“It won’t fit.” you yawned.

“You’re right,” he agreed. He rubbed your back for a few moments. “It’s my turn to check on you.” they had set up a rotation of who would take a peek at you every night. “So I’ll see you in a little bit, princess.”

You didn’t stir when he checked on you later that night. You didn’t feel him tap the front of your diaper. He looked at you and smiled softly, picking you up to carry to the bed he shared with Hanta.

Hanta welcomed you with open arms, snuggled you in bed and kissing your forehead while his boyfriend slid in behind you. You never woke, only stirring the tiniest bit so you could wrap your arms and one leg around Hanta.

Chapter Text

“I think it’s silly to have you sleep in your own room.” Izuku announced. You looked up at him, blinking and confused.

“Why?”

“Because we’ve all been taking turns waking up and checking on you.” he buttered a slice of toast and put it on your plate.
“And we work really heavy schedules. We need all the sleep we can get.”

“Then don’t wake up anymore.” you said through clenched teeth. “I can deal with it myself. You guys were the ones who wanted me to be checked.”

“We’re not leaving you in a wet diaper all night.” Katsuki snorted. “You’ll just get another rash, and that makes you moody as hell. I don’t think we need to deal with that.” you scowled as he finished his breakfast.

“You’re moody now,” Izuku noted. “But I have a plan for that.” you wanted to ask what, but Izuku didn’t seem in the mood to elaborate. You finished your toast and let Eijiro wipe off your face and hands.

You bid everyone a good day at work, alone with Izuku. He beckoned to you, leading you to his bedroom. You laid on the bed, confused. Wordlessly, Izuku took off your diaper, discarding it, leaving you bottomless and shivering on the bed.

“Hi baby,” he purred, leaning over you. You giggled a bit as he took your hands, kissing them and pulling them to your chest. He kissed you then, and you hummed into the kiss, lifting up towards them.

It felt like it was so long since you had been touched. Your legs opened as he kissed down your jaw. Izuku reached for a bottle. You looked at it curiously, gasping when you realized it was baby oil.

“Huh?”

“I can use this and it’ll keep you from getting chafed.” he smiled. You watched him open the bottle and pour a little on his fingers. Carefully, gently, he reached for your cunt. His fingers traced your labia, the space where your groin met your thigh.

You had to admit that it did feel nice. You relaxed under Izuku’s hands, so strong and gentle as he was touching you. A little more oil was poured on you, and you felt his fingers at your entrance. You whimpered, your back arching.

“My baby is so sweet.” he sighed. “How could we forget that our baby needs to be touched.” he rubbed circles around your clit. He gave it a few taps. You keened. Izuku laughed, a dark chuckle that made you shudder.

“Please,” you whispered.

“Please what? You need to use your big girl words.” he taunted.

“Please make me cum,.” your face burned while you said it. Izuku laughed again, nipping at your collarbone, nuzzling between your breasts. That seemed to be what he wanted to hear, because his finger was going faster, applying that pressure that you loved. Sometimes you hated that they could play your body so well, all of them.

“My princess needs to cum? I’ll make you cum. Relax, relax,” his voice was muffled by your flesh. You whined, your hips bouncing against his hand. Two fingers slipped into you and you moaned, clutching at Izuku. You wrapped your arms around him, fingernails digging into his skin.
“You’re so tight, goddamn. No matter how many times we finger you or fuck you. You’re always gonna be tight aren’t you?”

You whined, unable to speak real words. Izuku crooked his fingers inside of you, his other hand rubbing your clit. You screamed as you came, spasming around his hand. He cooed, speaking sweet nothings through it.

“Sweet baby,” he hummed. “You feel better? I know I do.” your shaking hands reached for his pants. Izuku stopped you, holding your hands.
“No no, honey. Not this time. This was for you. Lay still.” he slipped off the bed and grabbed another diaper and a can of powder.

“Don’t need it.” you mumbled. Izuku rubbed your belly. He slid the diaper under your bottom, ignoring the way you squirmed, uncomfortable. He rubbed in the powder, enjoying the blissful look on your face.

“There you go,” he taped you up, patting the front of the diaper, laughing when you gave him a dark look.
“Here, honey,” he had a cotton dress with a flower print, something that you might have expected to see in the little girls’ section of the store. You wanted to protest, but you felt too relaxed. Your bones could have been made of gelatin.

“You’re not grossed out?” you asked carefully. He frowned, sitting on the side of the bed, stroking your cheek.

“About what? We’ve always had this kind of relationship. Kacchan doesn’t mind either.”

“But um, I’m wearing… a diaper.”

“That doesn’t bother me.” he assured you. “Come on, let’s go. We can’t spend the whole day in bed.”

“I could,” you mumbled. You sat up, thinking for a moment. “I could go to work.”

“Oh, work.” he seemed to wilt. “I’ve been meaning to tell you.”

“What?” you demanded.

“Well… work….” he squirmed. You glared, waiting. “They let you go.”

“They let me go!” you repeated. “I was calling in.”

“I know, I know.” he sighed. “But honey, it was such a stressful job and there will always be another. Don’t you think that this is for the best?”

“But how am I supposed to pay for anything!”

“Did it not occur to you, my love, that us taking care of you and making all the choices means that we pay for everything?” he smiled.

“But how can I pay my part of the bills?”

“We don’t need your money!” Izuku laughed. “Come on, stop pouting love.” he stood up, helping you off the bed.
“We need you to be happy and healthy, and that’s what you’re working on. So it’s fine.” you didn’t like the thought, though. You’d have to get a job the very moment they quit with this diaper thing and let you be a real adult person.

***

“But I can sleep in my own room.” you said when Izuku brought it up again that night after dinner.

“You could,” he agreed. “But it’s harder for us to keep an eye on you that way. What if you needed help in the middle of the night?”

“Why would I need help in the middle of the night? Is that not the point of the stupid diaper?” you snapped.

“That’s when I can tell it’s bedtime.” Hanta chuckled. “She gets snarky.”

“I am not snarky. I’m frustrated.”

“Then how about because we told you to. We’re making everyone’s lives easier.”

“But I already peed.” you didn’t like admitting it. But Denki walked you to the bathroom every evening before putting you in your bedtime diaper. He liked watching you standing in the tub. He liked seeing you wrestle with the demand.

“So what?” Hanta shrugged. “That doesn’t mean you won’t wet the bed. And we can’t leave you sitting in a wet diaper all night.”

“So you’ll sleep with us. You’ve done it plenty of times before.” Izuku finished. You sighed. How could you get him to understand that it was different when you wanted to be there? Especially when you went in for a cuddle or to watch a movie or to give someone a blowjob.

“Are you tired?” Eijiro was asking, but it wasn’t really a question. He moved to scoop you up, listening to you squeal when he did.
“Let’s get to bed, princess.”

You pulled off your sweat pants. Eijiro was a furnace, you thought. And he liked to cuddle. You couldn’t sleep at all with pants on. He laid down and held open his arms for you. It was kind of early for him, you knew that. But you were yawning and rubbing at your eyes as you crawled into bed to cuddle with him.

“I don’t mind you sleeping with me, princess.” he kissed your forehead. “You’re always welcome to come in with me.”

Chapter Text

“What’s wrong with you?” Katsuki barely glanced up from the television when you were squirming on the couch next to him.

“I gotta pee,” you grumbled.

“Okay?” he finally looked at you.

“So I’m gonna have to untape and retape my damn diaper, and it’s a pain.” it was, you thought. It was a pain and it was difficult and it frustrated you. You’d rather just not pee at all, if you were being honest.

“Or I could change you when you’re done.”

“That’s worse,” you sighed. “I can pee by myself.”

“I’m not doubting that. It’s the diaper change part that you’re struggling with, isn’t it?”

“Forget I said anything.” you mumbled, standing up to head to the bathroom. Katsuki grabbed your wrist and hauled you back to him. You fussed for a moment, pushing against him, wanting to get up and pee before you found yourself in a predicament.

“Here,” Katsuki arranged it so you were straddling him, your arms around his neck. He kissed your cheek, letting you hide in him.
“Pee,”

“I can’t!” you squealed. “That’s so–that’s so gross.” you swallowed hard.

“How?” Katsuki questioned. “You’re wearing a diaper, they exist for you to piss in.” he snorted.

“But not here,” you shook your head.

“Okay,” he stood up and carried you to the bathroom. You were relieved when he set you down and lifted the toilet lid. Finally! You were getting used to being watched while you peed. After all, you had to perform for Denki each and every night before bedtime.

So many times you ended up on your knees in the tub, hiding your tears while he stroked your hair and told you how good you were. He’d hold your hands, giving you a squeeze when you finally pissed, relieved.

And when he changed your diaper, with you laying on the bathroom floor, he’d whisper to you how amazing you were. How proud he was of you. It made your mind feel gooey, made you want to be held. He’d change you, his fingers rubbing against your cunt as he did so. If you’d been good that day, he’d finger you to orgasm, then diaper you
up when you were brainless and limp, carry you to his bed.
You knew they were all meant to take turns with you in bed. It was supposed to make things easier. But more often than not, you seemed to end up with Denki and Hanta. Not that you minded, you found yourself loving when they cuddled you in their bed. You even liked waking up, feeling one of them moving you gently, getting you changed, and then being allowed to curl up with whoever was still in bed.

You’d be praised and loved on, falling back into sleep until you were carried to the breakfast table. It was only then that you’d wake up, slowly and carefully. It was much nicer than having to wake up to a screeching alarm, you thought. And you did sleep better in a big bed with two of them than you would have in your own narrow bed.

“What are you doing?” Katsuki asked as you moved to untape your diaper.

“Uh, going pee?” you froze, confused.

“Sit,” he pointed to the toilet.

“I–I will? When I get this off–.”

“No, idiot.” he grabbed you elbow and forced you to sit down. “If I wanted your diaper off, I would have taken it off. Now, go ahead and piss.”

You whined, squirming. You were beginning to deel desperate, and you didn’t know how to express that. Logically, you understood what Katsuki was saying. You were in a diaper. It wasn’t going to be a mess. And if there was, you were sitting on the toilet…

But emotionally, the thought made you want to scream. You clamped down, not wanting to piss this way. Katsuki leaned in the doorway, arms crossed, smirking at you. Out of all of them, Katsuki was the one that you knew you weren’t going to be able to sweet talk or pout at to get your way.

“Please,” you whined, squirming.

“You’re gonna hurt yourself if you hold it too long.” he shook his head. “And I don’t wanna hear about you not feeling good because you ain’t smart enough to just piss when you need to.”

“It’s hard,” you shook your head.

“It is the easiest thing in the world.” he shrugged. “And I got all the time to wait until you manage.”

You closed your eyes tight and willed yourself to relax. You blew out a breath. Your bladder couldn’t wait anymore, and you released. You pissed, feeling the diaper wicking it away, leaving you hot and damp.

But it never seemed to end! You felt the diaper swell as you spread your legs on the toilet, not wanting to squish the sodden material. Katsuki hummed and stepped into the bathroom, going under the cupboard to grab the changing mat Denki bought. He’d found one that was pink, covered with smiling cat faces. It was so babyish, you wanted to hate it.

But it was so much nicer than laying on bare floor.

“All done?” he didn’t glance at you, going to the wipe warmer, grabbing the powder. You nodded, refusing to meet his eye.
“Good girl,” he hauled you off the toilet. “You really had to go potty, didn’t you?” he teased. “Good thing my girl is all padded, or you would have had quite the accident.” he patted the front of your diaper, laughing when you whimpered and tried to turn away.

“Don’t,” you protested.

“It’s okay, it’s all out of love, babes.” he helped you lay down on the floor, untaping the diaper and wiping you. You loved the warm wipes, you had learned. They weren’t so harsh or jarring. Now all of them had a warmer in their rooms, as well as the one in the bathroom for you.

He powdered you, then taped a clean one onto you. He didn’t help you up, wrapping his hands around your hips. You looked at him, feeling strange there, no pants and your pink diaper on display. He looked down at you for a moment before leaning down, capturing your mouth with his. You moaned into the kiss, reaching to wrap your arms around his neck.

“Katsuki,” you whispered.

“No one has ever trusted me like this before.” he lifted you up, carrying you bridal style to the living room. He arranged you in his lap, your back to his chest. He flipped on the television and began to pat your thigh idly, like you would have patted a baby you were trying to coax to sleep, or comfort.

“This is cozy.” Izuku noted when he stepped out. He grabbed a blanket, pulling it over your lap and his lap. You hadn’t realized until then that Katsuki had not put your pants back on. You wanted to go and grab another pair.

But… it was only the two of them, wasn’t it? And you were comfortable, and warm, and Katsuki was holding you. And Izuku slipped in under his arm, so it was like a big cuddle fest, and how could you get up?

Chapter Text

“Here ya go,” Eijiro put down the water bottle on the table. You shook your head, pushing it towards the side.

“That’ll be the third one. I’m flushed out.” you insisted.

“But if you’re in diapers, we have to make sure that your urine stays–.” he began. You whined and clamped your hands over your ears. You were tired of hearing things like that. It wasn’t going to help any, you thought. It didn’t make anything better, didn’t make it easier to be in the position you were in.

“Stop it!”

“What is your problem?” Eijiro paused, giving you a serious look. “You’re way worked up.”

“I have to pee,” you grumbled. You had two options. You could either sit on the toilet in your diaper, or you could ask whoever was with you that day would take off your diaper and let you go to the bathroom bottomless. You’d get a diaper put back on after you were done.

“So why does that have to be a problem?” Eijiro parked it on the couch. You rolled your eyes and dragged yourself over to him. You lifted your t shirt so he could unbutton your pants and ease them down your body.
“You’re in a diaper.” he shrugged.

“I know,” you said through clenched teeth. “So help me pull my pants down so I can go piss.”

“But I don’t need to.”

“I don’t wanna sit in the diaper. Please?” you were quick enough to fall into pleading. You wondered if that was a sign of something. You couldn’t quite figure out the significance of it, not in moments like this, anyway.

“Then don’t,” Eijiro said between sips of his own coffee mug. You stared at him, waiting for him to elaborate. You were shaking your leg, trying to keep a hold on things.
“You’re overthinking.”

“Because I don’t understand.”

“Want help?” he set the mug down. You shifted your weight from foot to foot, trying to get to a comfortable place. You chewed on your lower lip, trying to make up your mind. You weren’t going to be able to ask Eijiro what he meant, you knew that. It was a yes or no offer.

“Yes,” you said. He smiled and held out his arms. Confused, you walked towards him, wondering if he was going to carry you to the bathroom. Instead, he picked you up to place on his lap, your back to his chest.

“There we go.” he murmured in your ear. “This is comfortable, isn’t it?”

“No,” you admitted.

“I’ll help,” he grabbed your arms, lacing your fingers together behind his head. He opened your legs wider, your knees outside of his. His hands rubbed at your belly for a few moments, a comforting motion that made you go still.
“There we go, hi baby.” he murmured.

“Eiji,” you muttered, melting into him. He nipped at your neck, smiling when you giggled.

“Where is it?” he asked aloud, although you were fairly certain that he was talking to himself. He reached down low, in your pelvis and smiled.
“There we are.”

“What?” you squirmed a little. He pressed down then, making your bladder cramp. You gasped, your back going straight as you tried to lift your weight up. He wrapped an arm around you, pressing you down hard.

“Nope, you stay here.”

“I can’t,” you stammered. Eijiro’s hands moved and he was undoing your pants, pushing them down. You were left sitting there in your diaper. That was somehow even worse. You tried to launch yourself off his lap, but he was so strong, and you couldn’t force him off.

“That will help, won’t it?” he hummed. Your hands held tight,your knees pressing against him. He gave your belly another little rub and pressed again. The steady pressure made you whine.
“You can whenever you’re ready.”

“It’s hard,” you whimpered. He made a sympathetic coo and pressed down hard. You tried to clench your pelvic floor. But Eijiro knew how to keep a steady pressure. You bit your lower lip when he eased up, giving you a moment’s peace.

Only a moment. He was pressing back down again. You moaned, unable to fight it. A tiny bit dribbled out, and Eijiro was smiling into your neck. You wanted to ask him what he thought was so funny, but you couldn’t focus on that. You were pissing, crying out as you did so.

“Right there,” he noted. “No, keep your butt in my lap.”

“I’m sorry,” you sobbed.

He kept pressing at your belly, his other hand going between your legs, feeling your padding as it expanded with piss. He rocked slowly, waiting until the heat against his palm stopped growing. You were whimpering, wiping at your eyes.

“Such a cry baby,” he teased. “But that’s okay, because you’re just a baby, aren’t you? You’re our baby.” he laid you down on the floor. You stared, having fully expected that you’d be taken to the bathroom.

“I am not a cry baby.” you managed as he grabbed a diaper from the little bin stashed next to the couch. He had a packet of wipes too. You winced when the cold material wiped your skin. Eijiro slid the diaper under your lap and taped you in. He didn’t bother to try and get your pants back on.

“You are a cry baby,” he disagreed. “But you’re our cry baby.” he kissed you on your lips, smiling when you returned the gesture, trying to press yourself into him.

“Big girl,” you tried to insist. He laughed and arranged you on his lap again. Your hips were grinding against his. Your head was falling back, fuzzy and dizzy. He rolled his hips up to meet you, pulling your head down so he could press kisses to you again and again.

“Is my big girl gonna cum?” he teased. “I wanna feel it.” you whined, spreading your legs wider, trying to get enough friction in the diaper. He snaked one hand between you, rubbing your clit through your puffy padding.

“I wanna,” you bounced in his lap, desperate for the friction and the pressure.

“Cum baby,” he coaxed. “‘Zuku said it did a lot for your attitude and headspace. Cum, baby, you’ll feel so much better.”

And then you were cumming in the diaper. You felt your cunt clenching around nothing. Your head fell back, digging into Eijiro’s shoulder. When the spasms finished, Eijiro cradled you in his arms. You felt so limp, so drained. Your brain was an empty blur.

“Oh!” Hanta said as he stepped in. “I did not expect this.”

“Baby’s been good today,” Eijiro nuzzled your head. “Take your shower and then you can cuddle her.” Hanta stepped close to you, tilting your chin up for a kiss against your parted lips.

“Can’t think of anything I want more.”

“I don’t need a bedtime, you know.” you scowled at Izuku when he was hinting around that it was starting to get late enough for you to go through the bedtime routine.

“No? We agreed–,” Izuku began in the drawl that he slipped into when lecturing. You had seen it strike awe in the hearts of elementary school kids. Not you, you thought. Nope. You crossed your arms to glare.

“She has a point.” Hanta shrugged. Everyone turned to look at him. “She says she’s grown enough not to need a bedtime, we should give her the benefit of the doubt. She’s been doing well.”

“Sure,” Eijiro jumped in. “We don’t need to put her to bed. She’s a big girl right now.”

Izuku fell quiet. You grinned, triumphant. You were sitting on the couch criss cross with a lap desk. You had a small diamond painting you were working on, and you had been entranced. You finished what you were doing and put your mess away.

None of them were looking at you. Denki was on Hanta’s lap, watching television. Katsuki and Izuku were squished together on the oversized chair, each reading their own files. And Eijiro was busy on his phone.

It was the first time in a long time that you were being left alone. You smiled for a bit, enjoying the quiet. And then it dawned on you that you were quite sure what to do. You squirmed a little bit on the couch, rubbing your thighs restlessly.

Your body was demanding that the routine be followed. You were shocked at how off kilter you felt about it. You were aching to get up, to go to the bathroom. No no no, you shook your head. You were fine. You didn’t need any of that!

You tried to focus on the television show. It was some low dialogue action show, where the women served as decoration or plot devices, rather than active characters. Even on your best days you couldn’t follow it well.

“Hey,” Denki lifted his head from Hanta’s shoulder. “Are you okay?”

“Um, what? Yeah!” you blinked hard.

“You look a little spaced out.” he frowned. You brushed it off, looking back to the television. No one spoke. You were squirming in place on the couch, shocked at the discomfort you were feeling.

“Be still,” Katsuki didn’t look up. You focused on being still on the couch, like a statue. Your skin felt itchy, and you had to give in and rub your arms, pleased with the self soothing that it brought. You barely noticed Denki sliding off Hanta’s lap.

“I’m feeling a little lonely.” he mused. You looked over, confused. He was just with Hanta! But he was looking at you with a mock frown. You scooted over, happy to be able to flop against him.
“Thank you, babe.”

“We’re wasting electricity with all these lights and the television on.” Katsuki announced. Eijiro set aside his phone, turning out the lights. Instead, a soft lamp next to Katsuki and Izuku was turned on. The room was mostly dark, with that one spot of warmth.

“Hanta, hon, can we turn on something a little–less?” Izuku asked. “All the action scenes are giving me a headache.” Hanta nodded and flipped the channel. The screen was filled with a much softer show, some drama with pretty clothes.

“I need a blanket.” Denki announced. Eijiro was there with one, wrapping it around the two of you. Denki yawned and stretched, wrapping his arms around you. The room was nearly silent. Eijiro came to join you on the couch, moving your legs into his lap. You were laying across the two of them now, still snug under the blanket.

Your feet were bare, and Eijiro began to massage them. You relaxed, Denki’s fingers in your hair, playing with it and rubbing your scalp. You were asleep before you knew it. They remained quiet for a time, making sure you fell deep asleep.

“Such a brat,” Katsuki snorted.

“If you’re gonna name call, looks like you can get her into her bedtime diaper and some pajamas.” Denki gave him a mock wounded look. The blond snorted and walked over, picking you up easily. He patted your bottom lightly.

“If I change her then she’s sleeping in our bed.” he warned. No one said anything, and he turned to carry you to bed. You didn’t stir as he laid you down, getting your changing supplies. You only mumbled in your sleep when he lifted you a little to slide a fresh one under you.
“No, be quiet. Stay fucking asleep,” he said in a sweet tone. He reached up to run his fingers down your forehead, over your eyelids until you were still again.

***

“Oh, you want me to get you ready for bed tonight?” Izuku laughed when you approached him the next night. You blushed and looked down at your feet.

“I like being put to bed.” you managed.

“All right, then we can put you to bed.” he stood up. “I wanted to put you to bed anyway.”

“Because you didn’t like me hanging out in the living room?”

“No, no, no.” he rushed to shake his head. “I’ll show you.” he was ushering you to the room he shared with Katsuki. You were dry, you knew that. What else would possibly excite him? He took you to the bathroom, sitting you on the closed toilet while he put toothpaste on the brush for you.

“I can do it myself.”

“I know you can, but I like to.” he shrugged. Well, if it was for him, who were you to say no? You opened your mouth, feeling him grab your chin and carefully brush each and every tooth. You rinsed and spat, then felt him carefully washing your face.

“Thank you,” you said, feeling bashful. He kissed you, his mouth so much warmer than yours. You let your tongue press at his lips until he opened his mouth to let you in.

While kissing, Izuku worked on taking off your clothes. He finally broke the kiss and you saw he had another piece of fabric in his hands. You lifted your arms without thinking. It was soft, you noted as he pulled it down your arms. Your head popped through the hole.

“Lay back,” Izuku smiled. You did so, freezing when he reached under and behind you to pull the rest of it down. This wasn’t a nightie like you originally thought. You felt him snapping something between your legs.

“Nope, no, no way!” you saw the print of the outfit, little rainbows. “Where did you even find a onesie this big? I don’t want it!”

“How is it much different than wearing a romper?”

“Because this was made for babies!” you reached to unsnap it.

“Ah ah ah,” he grabbed your hands. “No. You know we made the rules and you do what you’re told.”

“Take it off, ‘Zuku.”

“No,” he said again, firmly this time, no room for bickering. “This is a lot easier. We won’t have to take your pants off every time you need a change at night. It’s just like pajamas.”

“Then why can't I wear a nightie? Or–or one of your tshirts. Can I do that?”

“No, those kept riding up under you and your legs got tangled in them and you hated that.” Izuku shook his head.
“And you look so cute like this! I love it.”

“I don’t!”

“You do! Like you’re here and tiny for us to take care of. Because you belong here with us, don’t you?” he laid down and pulled you to lay on top of him. You leaned your ear in the middle of his chest.
“See? This is much more comfortable.” your bare skin was against his bare skin. His hands rubbed your back in little circles. And it was bedtime, you noted. And you were sleepy. Well, you reasoned, you could take this off before the others saw. And tell Izuku in the morning that you hated it and never wanted to wear it again.

But for now, you could enjoy being held by Izuku, feeling safe and drowsy. Tomorrow you’d deal with all this baby nonsense.

Chapter Text

“Out?” you froze as Hanta mentioned it casually. “Out where?”

“Out of the house. It’s time that you got some fresh air and sunlight. You can’t stay cooped up in here forever.”

“I’m supposed to be resting.” you blinked.

“Resting doesn’t mean motionless, dear.” he laughed. He was gathering an outfit for you. Where did these clothes keep coming from, you wondered desperately. He beckoned you over. You had been wearing a t shirt and sweats, since those seemed to accommodate the fluffy diaper the best.

But you made your way to him, lifting your arms when directed. He stripped off your top and sweats, pulling another onesie over your head. You whined, plucking at it.

“Izuku said these are only for sleep!”

“I know, I know.” he soothed. “But this is the easiest way to hide the diaper, right?” he snapped the crotch and smoothed the material over your shoulders. He pulled a skirt down. It was pleated, and looked closer to what you’d see a younger girl in. But it did cover your diaper, at least. And the onesie was a plain pink one, it didn’t have any cutesy designs. If no one knew what they were looking at, it would pass for a top.
“You’re so cute,” he gushed.

“No,” you shook your head. “I’m a freak. Freaks aren’t cute.”

“Did someone say something to you?” Hanta asked, hands on your shoulders. You shook your head. He said nothing, only set you to sit on the floor between his knees. He carefully brushed your hair and then gathered it in two high pigtails.
“You’re not a freak.”

“Clearly I am!”

“No,” he said sharply. “You are a person who has needs and you’re getting them met so you can be the healthiest version of yourself.”

“But–.”

“Hey,” he tilted you back, looking down to meet your eye. “Who is in charge here?”

“You,” you admitted sullenly.

“Right,” he smiled, rubbing your cheek with his thumb. “So you need to listen to what I say. And I said you are not a freak, and no one has any business saying something like that about you.”

“Yes,” you said softly.

“All right then, babes, let’s get a move on.” he helped you up, hands under your armpits, and then got himself up. He did let you put your own shoes and jacket on, at least. He snagged a bag you hadn’t seen before, one that could clip around his chest. Maybe you thought he just didn’t want his keys in his pocket. But when you got to the car, you were surprised when he directed you to the backseat.

“I can’t sit up front?”

“Nope, you’re safer in the back.” he even leaned into the car, buckling you himself. You were gobsmacked, unable to say anything as he closed your door and went around to drive. He did play the radio as you drove, glancing up at you now and then in the rearview.

It was nice, you thought, to watch the scenery as it went back. How long had it been since you sat in the backseat of a car? How long had it been that you were able to relax during a car ride? You were usually frantically adding things to a grocery list, or trying to map out the most efficient way to run all your errands.

When the car stopped, you looked out the window and blanched. Hanta said nothing, unbuckling himself and tucking his phone and keys into the bag and putting it on loosely.

“What’s wrong?”

“I can’t. I can’t!” you insisted. “I cannot go to the mall in a diaper.”

“Yes you can,” he came around and opened your door, kneeling down to talk to you. “No one is going to know. Now, I need a few things, and I think you’re being well behaved enough to pick out something special. I know you can be a big brave girl and make it through the mall.”

“Okay,” you acquiesed. At least it was the middle of the day on a weekday, so it wouldn’t be flooded with people. You held Hanta’s hand as you walked in. He went to a menswear store and began to sift through the shirts. You put your finger through his belt loop, wanting to stay close to him.

No one seemed to pay a whole lot of notice to you. There weren’t even many salespeople around. Hanta had a handful of shirts and began walking towards the fitting rooms. You made a beeline for the chairs.

“No, babe.” he caught your wrist. “I can’t leave you out here by yourself.”

“Yes you can.” you said through clenched teeth. Hanta raised an eyebrow, and you sighed and let him walk you into the fitting room. It did at least have a door that closed, even if there was a large gap at the bottom and the top. You stood there while Hanta took off his shirt, trying hard not to stare at his chest, his arms, his abs, his back.

“Hm, this is too tight for my tape.” he noted, smoothing down an emerald colored shirt. “What do you say, babe?”

“I love the color.” you were picking at your lip. He grabbed your hand and kissed your fingers, encouraging you to leave it down at your side. He hung the shirt up and tried on another one, this one black. The urge was starting to hit you.
“Hanta.”

“Hmm?” he didn’t look away from the mirror.

“Are–are you almost done?”

“Not really,” he glanced. “What’s wrong?”

“Um, nothing.” you shifted your weight. If you were an adult, you reasoned, you could hold it while he tried on shirts. But you had forgotten that Hanta liked to compare and contrast, so he’d put on and take off the same shirt three times. By the time he was done deciding he liked the black shirt, you were squirming in place.

“You need to go potty?” he asked casually. You whimpered and nodded, feeling your face burn.
“Go ahead.”

“Where’s the–.” your hand was on the door.

“No,” he pointed at you. “You’re not going alone.’

“Then come with me.” you begged. He shook his head, unmoved by your plight. Instead, he grabbed you, pulling you against him to stand in front of the full length mirror in the dressing room.
“Stop!”

“No,” he whispered in your ear. He reached under your skirt and undid the crotch buttons. He lifted the skirt, and the bottom of your onesie up. You were left staring at yourself in the mirror. You looked mortified. You felt humiliated. You squirmed in his arms, frantic to escape.

But Hanta was a pro, and he was always stronger than you. He kept your arms across your chest with one arm, the other holding up your clothes. He pressed a foot in between yours, kicking them apart.

“Hanta,” you whined in a desperate hiss. He ignored you, locking eyes with you in the mirror. Your lower lip quivered, and you knew you couldn’t wait one second longer. You felt yourself begin to pee, watching with dismay at the diaper began to swell, holding every drop of your fluids.

For his part, Hanta was humming in your ear, swaying ever so slightly. Tactics you would use to calm an upset child, you realized. Your lip continue to quiver as you sagged against Hanta, finished.

“Aww, cry baby.” he teased. “What’s there to be upset about? You wet your diaper. It’s fine.” he kept your skirt up and reached to undo the tapes. You shook your head, trying to bat him away.
“Hey hey hey, relax.”

“You can’t do that here!” you were scandalized. “Someone will, someone will see or hear or something. You don’t even have any–.” Hanta rubbed your side as he reached and grabbed the sling bag he was wearing. He unzipped it and pulled out a small packet of wipes and a diaper, folded up to fit.

You were stunned. Hanta quickly undid the tapes on your current diaper, put it in a plastic sack that he also had in his bag, wiped you, and had a fresh diaper on you before you could really understand what had happened.

“Let’s go,”

There were a few trash cans outside the fitting rooms, easy to put the plastic sack in. You were shell shocked as you followed Hanta out. He was holding your hand, which was just as well, really. You were hoping the floor would open up and swallow you whole. You weren’t really paying much attention to what he was doing, or where he was going. He paid and walked you out of the store.

“Hanta?” you asked in a small voice. He gave your hand a squeeze.

“What’s up, babes?”

“Nothing,” you couldn’t think of what you wanted to say, couldn’t quite verbalize it. Hanta walked you into a gift shop.

“Pick something special.” he waved his hand. You looked at him, confused. “Something fun, something you wouldn’t buy for yourself.”

“Something I wouldn’t buy for myself.” you repeated. How could you figure out what that would be, then? You blinked a few times and took slow steps through the gift shop, full of trinkets and toys and other fun things. Hanta watched you, looking amused.

You went to a wall of dolls. Your hand ran along the shelf until you paused. You stopped at a little heartshaped playset, something you would have loved as a child. You were in awe at the tiny dolly that lived in the little playset, small enough to be carried from room to room easily.

“That’s what my baby wants?” Hanta took it from you, walking you to the cashier. You didn’t make eye contact as he paid and began walking back to the car. You were quiet as he buckled you in again, that dizzy, fuzzy feeling creeping up you.

“Hanta?” you were about halfway home. He glanced up in the rearview, smiling at you. “Thank you.”

“You’re welcome, baby.” he grinned, such a genuine grin that it made your heart twist.

Chapter Text

What they didn’t know wouldn’t hurt them, you decided. If you were very careful and played your cards right, you were sure that you could get away with your plan. It was, perhaps, not the wisest choice you’d ever made to try it when Katsuki was with you for the day. But, you reasoned, you had to show them you could manage! Or they’d never believe you!

Katsuki got you in a clean diaper, kissing your cheeks after you were changed. He opened for some corduroy bottoms and a plain t shirt. You were docile as he got you dressed, closed your eyes when he brushed your hair.

Katsuki could be so gruff, you thought. You knew he struck fear into the hearts of those around him. You had no small amount of pride when you realized how strong he was. You had to admit that out of all of them, you always felt safe with Katsuki. Nothing was going to get to you if he was around.

“I got shit to do.” he announced after you were dressed. “Can you please try not to wreck the house?” you gave him the most innocent look you could and nodded. He rolled his eyes and went off to the office. You knew he was likely to wear headphones too, so that gave you another layer of freedom.

You held your breath and counted to 100 in your head. Once it was done, you fumbled under your bottoms and ripped off your diaper. Triumphantly, you tossed it into the trash with a huff. Now, you thought gleefully, you’d just have to not wet yourself before Katsuki came out. Then you’d show him you didn’t need the diapers and this whole babying thing could end.

You wondered what you’d do for work, now that you’d lost your last job. Well, you thought, they were right that the crappy jobs you tended to get hired for were a dime a dozen. There would always be a grocery store or cafe that needed you. There was the grocery store not far from here, walking distance. You could see yourself working there, walking home each night with a bag of fresh vegetables to be made into supper.

You parked it on the couch, flipping through the television. You thought you’d catch up on some trashy shows, but to your surprise, all you could find was cartoons and educational programming.

“I know we didn’t cut off the cable.” you muttered. Well, that was a problem for Hanta to sort out, he was the one that was best at this kind of thing. You put down the remote and lounged on the couch, watching the adventures of a blue dog, giggling now and then.

“Oi,” you snapped out of your thoughts, looking at Katsuki. He had another water bottle for you. “You need to go potty?”

“I am in control of my bladder.” you sighed. “I’m fine, Kacchan.”

“Whatever, see if I ask you again.” he grunted. That would work well, you thought. The last thing you wanted him to do was ask. You idly sipped your water and went back to the television. Eventually, you were bored enough to hunt out the coloring books and crayons they had for you, plopping down in front of the coffee table to work.

You had just finished a complicated picture of a castle when you stood up. You wanted to show Katsuki! He’d love it, you were sure. You grabbed the book, but as soon as you took two steps, you knew you were in trouble. You had to go. Now.

If you had been wearing the diaper, it wouldn’t have been a big deal. You would have had to go to Katsuki, listen to him taunt you about needing the damn thing, and then get changed. But there was always the chance that he would have given you a cuddle afterwards.

Okay, you thought, this is fine! You just had to make it. You began the careful trek to the bathroom, stopping every few steps to try and clench again. You didn’t make it far, of course. You felt your bladder give, piss trailing down your legs, puddling at your feet.

Katsuki was going to be livid, you thought.

But! Maybe you could change and clean up before he noticed? Then again, you didn’t know where they had been stashing your clothes, and you didn’t think he had a pair of pants exactly the same. He was going to notice.

“The hell,” sure enough, think of the devil. “What is going on here?”

“I can explain!”

“I’m listening,” he crossed his arms, glaring at you. Your mouth opened and closed like a fish. There was no explanation. Katsuki scoffed and disappeared to the kitchen, returning with paper towels and sanitizing spray.
“Stand right there,” he pointed to a wall. You walked over there, your pants clinging to you. You watched him clean up the mess, fearing bubbling up inside of you.

“Katsuki?”

“We will talk when I am ready.” he got up from the floor to throw away the paper towels. You listened to him washing his hands. This waiting was agony. When he came back, he grabbed you by the arm and walked you to the couch. Without a word, he pulled your pants down. Before you could think, he had you over his knee, one leg around yours.

“Wait! Stop!”

“No,” he said in a clipped voice. “If you’re going to act like a disrespectful brat, I’m going to treat you like one.” you ass was bare, and you just knew this was going to hurt. Katsuki was big, and he was a pro.

He didn’t warn you as he began to spank you. He focused on your sit spots. You wondered how he knew where to hit and exactly how hard to land the blows. But you couldn’t think about it too long, because you were in tears.

You knew he wasn’t using his full force, but he wasn’t gentle either. After about fifteen swats, he stood you up, pants still down around your thighs. He was pissed still, you could see it in his eyes. Wordlessly, he pointed to the corner. You moved to pull up your pants, and he smacked your hands away.

“If I wanted your pants up, I would have pulled them up. Go,” he snapped his fingers. You waddled over, feeling for all the world like a tiny baby. You kept wiping at your eyes, your bottom stinging, feeling cold and lonely.

“Oh no,” Izuku murmured when he opened the door and saw you with a bare ass and wet pants in the corner.
“What did you do, baby?”

“It was an accident!” you exclaimed.

“It was not!” Katsuki argued. “You took off your diaper!”

“Oh, love.” Izuku sighed. You weren’t sure if he was talking to you or Katsuki.

“I’m sorry,” you whispered.

“You fucking better be.”

“All right, all right.” Izuku put down the bag of groceries he’d brought home. “Kacchan, please go and put those away.”

“You can’t coddle her after she’s been in trouble.”

“I’m not. The two of you need to be separated. You know we have to decompress after a punishment. You’re too angry to do that. And you have reasons to feel that way.” he was walking you to the bathroom.

Katsuki snatched the groceries and stormed to the kitchen. Izuku began to strip off your clothes, starting the shower for you.

“Stop crying, love. You were frightfully naughty, you know that.” he scolded softly. You sniffled a bit and stepped into the tub. Izuku grabbed the shower hose and washed you down. He was careful with the soap. He might have been frustrated too, you thought, but he was being kinder than Katsuki.

“I wanted to show that I didn’t need them.”

“But you obviously do.” Izuku pulled you out of the shower, drying you off. He walked you, naked to the living room. Katsuki was sitting on the floor, that stupid change mat down. He beckoned to you and you went and laid down.

The same hands that had spanked you were gentle and careful, rubbing oil in some places you were likely to chafe, powdering you as well. The diaper was taped up, but he didn’t even give you a shirt.

“Kacchan?” you asked timidly. “Where are my clothes?”

“Oh, you don’t need any.” he shrugged carelessly.

“I do!”

“No,” Izuku shook his head. “I've adjusted the temp, it’s warm enough in here. If you’re not going to wear your diaper like a good girl, we’ll have to monitor you. And we do that best when you have no pants on.”

Your jaw dropped. But the two of them continued like nothing was wrong. There wasn’t even a throw blanket in the living room. You were sitting on the couch, just about naked, trying to curl into yourself when the others came home.

“What do we have here?” Eijiro asked, walking over to kiss you hello. “Where’s your clothes?”

“Um,” you looked down at your lap.

“Go on,” Katsuki demanded. “Tell them what you did to lose the privilege.”

“I um, well, you see, I was trying to…” you trailed off. All three of the guys were looking at you intently. They offered no way out of it, simply waiting for you to respond.
“I took off my diaper and had an accident.” you finally blurted. “And Katsuki spanked me and made me stand in the corner and now I can’t have clothes.”

“Sounds reasonable.” Denki agreed. You gave him a sad look, hoping at least one of them would be on your side.

“Yeah, consequences for actions.” Hanta shrugged.

“Can I have a blanket?” you asked.

“No,” Eijiro ruffled your hair. “It’s warm in here. After we shower and change, you can sit with one of us.”

As if! You didn’t want anything to do with them! If they weren’t going to defend you, you didn’t want to sit with them. They left and came back in lounge wear. Eijiro patted his lap, but you violently turned your head away. You were even more upset when the others snickered.

“Mad about it now, brat?” Katsuki asked as he walked by. You crossed your arms in a pout. You realized on some level you looked even more childish. Sitting there on the
floor, mostly naked, sulking.

No one seemed to pay you any attention, talking amongst themselves, putting something else on the television. How they were able to get past the kids shows, you didn’t know and were too proud to ask.

Gradually, you realized the house was getting chillier. You shivered, curling in on yourself. No one else seemed uncomfortable or even mentioned it. You scowled. You were either going to have to beg for clothes, or ask to cuddle or something.

“Love,” Izuku called quietly from the oversized armchair. “Why don’t you come here? You’ll be much more comfortable.”

“Because I don’t wanna!”

“You don’t wanna be comfortable?”

“No, I do want that. I don’t want it to come from you.” he hummed and stood up, walking to you and picking you up. You gasped and tried to shove away from him. Izuku only headed back to the chair, sitting you on his lap.

“Shh,” he cupped the back of your head, bringing it to his shoulder.

“Don’t shush me. I’m allowed to have feelings and express them. I am! I am!”

“Shh,” he said again. He had something then, a piece of plastic. You didn’t have a chance to examine it before he was pressing it between your lips. You froze when you felt the something pressing against your tongue. It was shaped, you realized, like a dick.
“There we go,” he smiled. “Something to help.”

“I don’t want this! I’m not a baby!” you spat it out into your hand. “I’m going to my room.”

“No,” Katsuki crossed his arms, glaring at you. “You’re in trouble. You’re going to sit with Izuku and keep that in your mouth. If you don’t, we have no problem strapping it on. So what would you like to do?”

You slowly put the pacifier in your mouth. Katsuki huffed and went to the kitchen, ostensibly to make dinner. Izuku cuddled you close. Even though you were feeling a little sour on him, too, it was nice to get warm, and to be able to hide in someone’s chest.

“That’s my baby,” Izuku whispered to you. “See? All better. You needed a cuddle and something to settle your mouth.”

You disagreed, but were in no position to argue.

Chapter Text

You were sitting on the floor, moving the little people that came from your play set. Once everyone saw how much you enjoyed it, it wasn’t uncommon for them to bring you home a new one to play with. You were responsible keeping them picked up, after all.

“Hey baby,” Eijiro smiled as he came in. You lit up, jumping up and running to him. He swept you up in a hug. You wrapped your legs around his waist. He spun you around, laughing. He didn’t set you down as he took off his jacket and shoes.

“Eiji’s home,” you said happily.

“I am! Where’s Han? I thought he was home with you.”

“Taking a nap.” you sighed.

“Aww, and he left you here all alone? Poor baby,” He patted your bottom, setting you on the floor. “I’m gonna take a shower, but then I can come out and we can hang out?”

“Yes, please!” one of the downsides of not working was that the days could stretch out. Without work, without a goal, you were more likely to be bored. It was nice that they stayed home with you, but since you didn’t have responsibilities, they did have to be a little more on top of things.

“I’ll be right back.” he kissed the top of your head.

You hurried to tidy away your playsets. You would make up stories in your head, playing them out silently in your head as you moved the little people around. But even adults could play with action figures! And maybe you weren’t playing, you were… you were coping. That was something adults did.

“And you picked everything up. Good girl,” Eijiro said warmly. You beamed and raced back to him. He lifted you up, going to sit with you on the couch. You snuggled on his lap, peppering kisses up and down his jaw.
“Does my baby feel some kind of way?” he laughed.

“Maybe.” you admitted softly. It made your face warm to admit. Eijiro hummed. He adjusted himself on the couch.

“Then I think you know what to do.”

“I do?” you whispered.

“My thigh is right here, baby.” he kissed you. You leaned into the kiss, sighing happily. It was nice to get at least some attention. Eijiro adjusted your legs so you were straddling his thigh. Your diaper crinkled as you moved.

“What… what do I do?”

“Ride it,” he shrugged. “I know you know how to do it. I’ve seen you riding my hands and dry humping me.” you felt yourself flush.
“Does the baby need help?”

“Yes,” you hissed.

He lifted you easily, facing you away from him. You gasped, surprised. You leaned your weight on your hands, letting his knee take your weight. He rubbed your hips, keeping a grip. You gave an experimental roll, feeling the pressure of him through your diaper.

“See? I knew you were clever enough to figure it out.” he praised. You rocked on his thigh, whimpering when he did that thing where he tightened the muscle. He laughed.
“Oh, you like that?”

“I do!”

“You’re such a good girl, aren’t you? See how nice it is to live a life that we direct for you? All you have to do is everything we tell you. And you’ll get plenty of rewards. And we’ll always make you feel good. Izuku was right, a baby that’s been made to feel good is a baby that listens. You don’t need all those stressful thoughts, do you?”

“No,” you agreed. He started bouncing his leg in time with you grinding. You gasped, your head falling back. Eijiro had a good grip on you, for which you were grateful. You leaned harder on your hands, having found the perfect position, your clit dragging against the soft material of your diaper.

“Just be our baby. Be brainless. We’ll tell you exactly who you need to be.” his words washed over you. You couldn’t quite grasp them, focused instead of chasing your orgasm. You were making those little breathy sounds that you always did when you were close.
“You’re almost there.”

“Eiji!” you whined. He released one hip to let his hand run down your front. He lifted you slightly, his hand pressing against the crotch of your diaper. His fingers were even nicer for you to grind on.

“Oh, there you go. Yup, move how you want. I can see your toes curling.”

“Eiji, Eiji, Eiji,” you babbled. “I’m gonna cum.”

“Do it,” he murmured softly. And so you did, stiffening on his thigh. You moaned, going boneless on his lap. Eijiro left his hand between your legs, his other arm wrapping around your waist to pull you back against him.

“I love you,” you said softly, breathy.

“I love you.” he adjusted you, your legs feeling like jelly. He kept his hand between your legs though, pressing your diaper.
“Go ahead and pee.”

“Huh?” you asked, feeling stupid.

“Pee so I can get you in a nice fresh diaper. You don’t want to wear something sticky, do you?”

“Um, okay,” you made to climb off him. He kept you in place, shaking his head.

“No, you’ve pissed on my lap before. You can do it again.”

“No, Eiji,” you tried to peel him off you. But he kept his grip.

“You know you need to do what I say,” he warned. “You don’t want to have to go and stand in the corner, do you?”

You didn’t want that. And your brain was still swimming in those happy chemicals, and you couldn’t think of a good way to argue. So you relaxed, feeling him rubbing your belly before pressing at that place he had found before.

“There it is,” his other hand stayed between your legs, feeling the pressure of your urine, feeling the expansion of the material.
“I knew you had to pee. Fuck, that’s so hot. Look at you just letting go. Not a thought in your head, is there?”

“Don’t,” you winced. “Don’t talk like that.”

“Why not?” he kissed up your neck, sucking just below your ear. You moaned, goosebumps rising on your body. You didn’t respond before you heard footsteps coming. Hanta smirked, rubbing his eyes.

“Were you a little antsy, baby?” he asked. “I thought you’d come and nap with me. But you could have woken me up. I would have taken care of you.”

“Can you get me a diaper and the change mat, Han? Someone needs some dry bottoms.” you blushed, but you were still enjoying your afterglow. You were limp when Eijiro laid you down, unsnapping your onesie.

Hanta sat down on the floor, too, playing with your hands. You giggled, looking at him with hazy eyes. He reached for the penis pacifier, popping it in your mouth. You sucked at it, eyes barely focused.

“Good girl,” he stroked your hair while Eijiro lifted your legs to put your clean diaper down. You were limp as he taped you up and snapped the onesie closed. Hanta picked you up and carried you to the couch, letting you zone out, suckling on that pacifier.

Chapter Text

“Because it’s easier than fussing about your pants.” Izuku explained as he pulled a fresh onesie over your head.

“Can we at least find plain ones that don’t look like this?” you whined, pointing at the cartoon cat faces that decorated the material.

“That’s asking a lot of us, isn’t it?” Katsuki glanced at you. You went silent as Izuku found a pair of fuzzy socks and pulled them over your feet. You were surprised that they went to your knees, but said nothing. He lifted you up to take you to breakfast, kissing your forehead as he set you down.

You poked at your breakfast until Denki finished his, taking your spoon and blowing on the oatmeal before lifting it to your mouth. You dutifully ate the oatmeal, sweetened with honey. Denki wiped your mouth and gave you a kiss before he got up to get ready for work.

“You’re with us today.” Izuku got you out of the chair and sent you to the living room. You parked it on the couch, looking at the television. Katsuki came in with his laptop, beginning to work.

“Let me find something for my baby to watch.” Izuku said as he stepped in. He put on some of the education programming and then went to a closet. He reached for a box, presenting it to you with a grin. You stared at the colorful blocks.
“You can build anything you like. Just pick up when you’re done.” he patted your head.

You sank to the floor, pouring the box onto the table. You grabbed the colorful blocks, stacking them. Your mind wandered, zoning out, blanking. You giggled when the stack collapsed, coming down the table with a clatter.

“Having a good time?” Katsuki asked. You looked up, smiling. You’d forgotten he was there. “You need a fresh butt?”

“No,” you scowled, resenting having been asked. You could figure things out for yourself if you were wet, you thought. If you didn’t give them a chance to check you, you could get to the bathroom yourself and change your diaper before they realized. It was a flawless plan, if you did say so yourself.

Katsuki went back to his laptop, and you went back to building. The bricks were maybe a weird size for your little people, you thought, but no one else needed to know. Who got to make the rules when you were just having fun?

“Here, sweetheart,” Izuku placed a water bottle down. You drank from it mindlessly, moving the blocks around.
“Is your diaper dry?”

“Yes!”you snapped. Izuku gave you a long look, and you went back to the blocks, disgraced. It was not dry, and you knew that. But you’d have to be careful about sneaking to the bathroom to get yourself changed. You weren’t sure how you could manage to get a fresh one taped up, but you’d figure it out. When he finally announced lunch, Katsuki grabbed your hand before you could go to the kitchen.

“Wait a minute,”

“Why? I’m hungry.”

He yanked you towards him, his hand going to your crotch. You blushed as he felt, glaring at him.

“You’re wet.”

“So?” you tried to pull yourself away. So much for your plan to wait until they were both distracted and sneak away.

“So, you’ve been asked twice. And you're wet enough that I know you’ve pissed more than once.” he unsnapped the onesie and took it off. You blinked as he untapped the diaper and removed it, wiping you with some wipes from a packet in a basket next to the couch. A new diaper was placed on you, and he looked satisfied.

But when he didn’t put the onesie back on you, you frowned. Izuku came to usher you to the table, and you followed, dumbfounded. He snapped a bib around your chest, and you looked down at it, shocked. You went to take it off when he stopped you.

“I made spaghetti.”

“So?”

“Watch your tone.” Katsuki warned with a stern look.

“So,” Izuku continued. “It’s going to get messy and you’ll get sauce all over.” he was putting a little plastic plate down, complete with a small plastic fork.
“This will keep you clean.”

“But if I’m not wearing clothes,” you coughed. “Then why does it matter?”

“Someone is getting whiny.” Izuku noted as he sat down. “And when that someone is whiny, it tells me they need a nap.”

“I don’t need a nap.” you said, exasperated. He didn’t comment, only ate his spaghetti. You ate yours, too, sitting still and letting him wipe your face when you were finished. You did a pretty good job, honestly. Only a few noodles and a tiny drip of sauce were left on the bib.
“Can I have my clothes back?”

“No,” Katsuki shook his head. “If you’re not going to tell us when you’re wet, we’ll have to be able to see.” you whined, squirming. Izuku looked over at you and came to pick you up.

“Come on,”

“What?” you glared, shoving at him, trying to slither down.

“You’re cranky, you need a nap.”

“No, I don’t!” you shouted. Izuku looked at you, eyebrows raised, clearly unimpressed. You pressed your lips together.

“I’m not going to give you another chance to do that.” he declared. He held out one hand and the damned pacifier was put into it. Damn how fast they could move, you thought. Damn how easy it was for him to force the pacifier in your mouth, strap it behind your head. You shouted, muffled by the silicone, pushing at him.
“That’s enough.”

You were trying to get away from him even as he walked to the bedroom he shared with Katsuki. He laid you in the middle and laid down himself on his side, looking at you. You glared, trying to sit up. Izuku’s hand came to your chest, pushing you back down gently. You huffed and tried to sit up again. Izuku pushed you back down. You made a high pitched sound in your throat.

“We make the rules.” he said gently. “And you’re tired and crabby and you need to rest.” you shook your head, embarrassed by the way that you were so frustrated. Izuku nodded and scooted closer to you. He wrapped you in his arms, and you knew you didn’t have a chance of getting away. Izuku chuckled, which only pissed you off more. You jerked your head to the side.
“Relax, babes, you’re fine.” he started rubbing your back, letting his finger tips draw shapes. It was soothing, and he was strong and warm, and it was soothing…

You were asleep. Izuku had initially thought he’d just get you to sleep and then go about his business .But having a sleepy baby in his arms, all cuddled up, looking adorable with her pacifier? How could he resist a nap, too?

Chapter Text

“Good morning, my love!” Hanta cooed as he moved you around, pulling up your nightie to access the diaper. You mumbled, rubbing your eyes. He grinned at you, your hair messy, your eyes blurry.
“Kats has some super yummy breakfast cooked. Are you ready to eat?”

“Yes,” you managed. He sat you up and pulled a shirt over you and a pair of long socks. You didn’t love your puffy diaper being on display, but you said nothing as he picked you up to carry you to the kitchen.

You were expecting Hanta to set you down next to Denki. Denki or Eijiro would usually help you at mealtimes if you were trying to avoid eating. Instead, he was sitting you down in a chair you had not seen before. You blinked in confusion as he grabbed a belt and buckled you into the seat. You shook your head, reaching for the clasp.

“Leave it,” Hanta said sweetly. He had something else in his hand, a wide piece of plastic that looked like a table. He slid it onto the chair. You gasped when you realized that you were in a high chair.

“What?” you said in a heavy voice, blinking. Denki was there with a bib, clasping it behind your neck. You shook your head and reached to pull it off.

“I’m not eating spaghetti. I don’t need this. Let me out!” you tried to reach for the tabs that would get the tray off. Hanta grabbed your hands and put them on the tray. He hand them, his palms over the back of them until a plate was brought to you.

You had been expecting a regular plate, like you nearly always ate from. But Katsuki had in his hands one of the divided little plastic plates. There was a helping of scrambled eggs and cheese, some strawberries that had been cut up, and a sausage patty that had already been cut up for you.

“Here’s your breakfast, fussbudget.” he ruffled your hair. You growled, wrenching your hands away from Hanta.

“Let me down.”

“You’re cranky because you’re hungry.” Izuku yawned. “Go ahead and eat.” but no one had given you a fork. It dawned on you that was by design. They wanted you to use your fingers. You scowled and moved your arm, intent on swiping the plate away. As you moved, your arm was grabbed and pulled back.

“Do not,” Katsuki growled. “You will be very sorry if you do.”

“Give me a fork.” you demanded.

“You are so grumpy this morning.” Eijiro laughed. He sat next to the high chair. He grabbed a strawberry and held it to your lips. Slowly, you opened your mouth and let him put it on your tongue.
“See? You just need to eat. Then you’ll feel better.”

You finished the strawberries and sighed as you ate the scrambled eggs, trying hard to be careful. It was delicious, the same way that everything Katsuki made always tasted good. When the plate was empty, Izuku came with a warm wet rag to wipe your face and hands, then the tray for your high chair.

“Go play,” he said as he put you down, patting your bottom.

You resented being told that and stalked to the living room, plopping on the couch and crossing your arms. You crossed your legs at the knee, scowling at all of them. It was one of the rare days when everyone had off, so at least you could let all of them know how unhappy you were.

“Knock off the attitude.” Katsuki snapped his fingers at you.

“Make me,” you said before you could think. The whole room went quiet. Eijiro was suddenly very interested in the mug of coffee he’d brought out. Denki was giving you a sad look. Izuku and Hanta exchanged glances.

“You asked.” Katsuki shrugged, going to the couch and hauling you off. He held your arm up high, his other hand came down on your bottom. At least this time he didn’t take off your diaper and smack your bare ass.

“Stop!” you howled.

“Watch! Your! Tone!” Katsuki said between smacks. You knew he wasn’t going hard, but it was still awful. You were crying as he finished. You were sobbing, face in your hands. All of them were quiet, but someone was walking towards you. Hands moved yours from your face.

“Shh,” Denki had taken one knee to speak to you. He cupped your cheeks in his hands, thumbing away your tears.
“Kats did warn you, babe. Shh, it’s okay, it’s okay.” he hummed picking you up by your waist.

“Kacchan is so mean to the baby.” Hanta cooed at you.

“I’m not a baby!” you insisted. “I’m not! I’m not!”

“It’s okay,” Denki said in your ear. “You don’t have to cry. You can sit with me, and in a little bit, and then when you’re calm you can go and see Katsuki. If you give him a hug and a kiss, I know you two can make up.”

Make up! Why would you want to make up with someone who had just spanked you for no reason? You sniffled and reached for Denki, burrowing into him to hide. The two of you sat together, with occasional kisses from him, your shoulders heaving as you cried.

“You’re okay.” Denki soothed. “You’re okay, baby. Go ahead and see Katsuki.” he set you down, even though you protested. The other blond was looking at you intently from his chair. You slowly shuffled towards him.

“Done being a snotty little brat?” he asked. You wanted to protest, but instead you nodded. Katsuki sat back in his chair. You reached out your hands silently. Katsuki picked you up and put you on his lap, wrapping his arms around your waist.

“See? I knew you could make friends again.” Denki beamed. You turned your face away, but leaned back into Katsuki. He rubbed your belly, kissing down your neck.

“Are you just a little crabby in the mornings? I get it. Not everyone is a morning person.” he murmured to you. “Let’s cuddle for a bit, and then we can play with your blocks that Deku brought you, okay?”

Chapter Text

If they weren’t going to listen to you, you thought, you were just going to show them how wrong they were. You slept in Eijiro’s bed, barely waking up when he unsapped your onesie to change you. You stirred, rubbing at your eyes. Eijiro made shushing sounds as he snapped you back up and grabbed a pair of knee high fuzzy socks for your feet.

You were mainly asleep when he picked you up and carried you to the kitchen. You whined when the lights met your eyes, pressing your face into his neck. Ejiro sat in a chair, rubbing your back as he did.

“She’s meant to be in her chair.” Katsuki grunted.

“Leave her alone,” he sighed. “She’s just a baby.” you stiffened when he said then and lifted your head.

“Put me down.”

“Aww, don’t let Kats get to you.” Eijiro cooed. You shook your head and squirmed to be put down. With a sigh, Eijiro put you in your high chair. It wasn’t perfect, and you could admit that. But it was better, at least. You were delivered a plate of mini pancakes, complete with a little puddle of syrup to dip them in.

You didn’t have utensils. You couldn’t help but notice that everyone else had knives and forks, and their pancakes were big. You wanted to fuss, but of course, that would likely result in them thinking that they had been right and you were a baby.

You ate neatly, careful to keep the syrup off your clothes and out of your hair. You were given a sippy and took little fake sips out of it. No one paid you much attention as you finished and Hanta wiped you clean, kissing your head and letting you out of the high chair.

Good, you thought. Phase one complete. You were sent to the living room, where you moved your blocks around and half paid attention to the television. You were given
goodbye hugs from Izuku, Katsuki, and Eijiro as they left. Best that you were with Hanta and Denki today, you thought. They were the ones you could fleece the best.

“We’ve got a lot of paperwork to do.” Denki admitted, looking a little disappointed. “Can you please be a good girl and sit in the living room?”

“Of course,” you shrugged. He beamed and picked you up for a swirly hug. You didn’t have to be a baby to enjoy that, you told yourself, giggling a little. He set you down so gently, so carefully, it tugged at your heart.

“Here, my love.” Hanta handed you a water bottle. “We’ll check in on you now and then.” you nodded as they went into the office.

All the better, really. If you were alone and they were busy, they were less likely to diaper check you. And you could finally demonstrate that you didn’t need this damn thing. You sat smugly on the couch, suddenly fine with the situation.

The cartoon you were idly watching wasn’t the worst thing, you thought. You weren’t exactly entranced by the giant bear who said that you smelled good, actually you thought that was a little creepy. But you appreciated his singing voice, at the very least.

You ignored the water bottle. When Denki and Hanta came out for lunch, they decided it would be more fun to eat in the living room. You were given a sandwich, and your water bottle was glanced at. They must have been terribly busy, because they didn’t comment on the fact you didn’t drink anything before disappearing back to the office.

Your mouth was dry, you thought. You snuck towards the kitchen, opening a particular drawer that you and Denki liked to keep hidden. You pulled out two pieces of the hard candy stashed there.

Sucking on the candy did help your dry mouth, at least. By the time you had finished and shoved the wrappers deep into the trash, the door opened. You lit up, seeing Izuku coming in. You ran to him, throwing your arms around his neck.

“I love when my baby welcomes me home!” he nuzzled your cheek. “Where are Denks and Han?”

“Paperwork,” you shrugged. He nodded thoughtfully.

“Been all alone all day? Poor thing. Let’s get you a fresh diaper and we can hang out.” you said nothing as he tapped your bottom and paused.
“Oh, they must have already.” he wasn’t asking you a question, so it wasn’t a lie if you said nothing.

Izuku plopped on the floor, laying back with you on his belly. He played with your hands while he and Eijiro chatted, making you clap and wriggling your arms until you laughed. Hanta and Denki finally emerged, ready to get started on dinner.

You knew they must have figured that one of the others had changed you. Everything was going according to plan, you thought happily. You sat politely in your high chair at dinner. Soon enough, you reasoned, you’d be allowed to sit in your normal seat again. You sat in the living room quietly until Izuku hinted that it was time for bed.

“Can I sleep with you?” you asked sweetly. He nodded enthusiastically and carried you to his room, choosing out a clean onesie and grabbing a diaper. He frowned when he realized that it was dry.

“Are you feeling okay?” you nodded innocently. With a sigh, he still put you in a clean diaper and snuggled you on the bed. You had to admit that you did love being cuddled. You nestled into his chest, feeling him rubbing your back as you dozed off.

***

“You stayed dry all night.” Katsuki sounded shocked. You sat up, feeling pleased with yourself.

“I guess whatever was wrong with me was resolved.” you shrugged. “Maybe I’ve relaxed enough. I should probably brush up my resume and–.”

“Hold it,” Izuku held up his hand. “We’ll make that determination. Do you have to pee now?” you shook your head. They exchanged glances. Something told you that it wasn’t going to end well for you.

“Your lips are dry.” Katsuki noted, looking at you.

“Chapped lips can happen to anyone.” you shrugged.

“Stick out your tongue.” Izuku demanded. You did so, feeling it sticking to the roof of your mouth. He narrowed his eyes.
“Come on,” he lifted you up and carried you to the kitchen, where the others had already gathered.

‘Good morning, little love!” Denki grinned, reaching for your toes. You didn’t react. Izuku looked at him and Hanta.

“How many wet diapers did she have yesterday?”

“Um….” the blond stammered. Hanta looked confused.

“Well, you changed her when you got home, right?” Izuku shook his head. Suddenly, you could feel all eyes on you, and you could almost see the wheels turning in their heads.

“How many water bottles did you give her?” Izuku asked, his voice too calm. You realized this was maybe not going the way you hoped.

“One? I think?” Denki blinked. Izuku nodded. He kept you in his lap as he ate his breakfast. The fact that he wasn’t upset was scaring you a little bit. Once he was done eating and the table was cleared, he parked you in the high chair.

“I don’t need this. I haven’t had any accidents. I’ve relaxed, and I can go back to my real life!”

“Hush, baby,” he said sweetly. That did not bode well for you. You were strapped in and he glanced at Katsuki and nodded. The blond smirked and hurried away. You whimpered, wanting to push the tray away.

When he came back he was holding something in his hand that you couldn’t quite sort out. He grabbed your wrist and shoved your hand into the soft pink thing. You gasped when you realized it was a mitt. The same kind they put on babies to keep them from scratching themselves. And they seemed to lock onto you.

“No!”

“Yes,” Katsuki said, putting your hands on the tray. “If you’re not going to make good choices, we’ll make them for you. We should have done that all along. After all, you are just a silly baby.”

“I am not!”

“There’s no reason for raised voices.” Izuku said in that high pitched voice he broke out when he wanted to baby talk you.
“But you’re grumpy because you’re thirsty. Open your mouth.”

“No,” you clamped the mitts to your mouth.

“You can open your mouth or have a sore bottom and still open your mouth.” Katsuki said darkly. You lowered your hands and opened your mouth. A pill was popped in. You held it on your tongue, feeling the bitterness of it melting.

“Swallow,” Izuku said. He grabbed your chin and pointed it upwards, rubbing your throat until he felt you swallow. You whined, not knowing what the pill was, hating the taste. He looked satisfied and handed you a sippy cup of all things. You had to grip it awkwardly with both mitts.
“Drink that.”

“I’m not–.” Izuku snapped his fingers and gave you a long look. You put the soft spout in your mouth and began to drink. And it was nice, you thought. Nice, ice cold, quenching. It did a lot for your parched throat. You drank until it was empty.

“Good to know you have enough sense not to be a total idiot.” Katsuki grunted, grabbing it to fill again. He dropped it back on your tray and walked out. You were alone in the kitchen. You drank the sippy, slower this time. Izuku drifted back through with another pill. You swallowed again, not daring to ask what it was.

Finally, he lifted you out of the seat and carried you to the living room, with yet another sippy. You were parked on Katsuki’s lap. He held the sippy to your mouth, refusing to let you stop until it was empty. Satisfied, he set it on the coffee table.

You didn’t speak, didn’t even watch the television. You were aware of the growing pressure in your abdomen. You whimpered, fidgeting in Katsuki’s lap. He said nothing, his hands going to your hips.

“Take me to the bathroom.” you said suddenly.

“Hell no.”

“What?” you craned your neck to look at him.

“I can’t trust you.” he snorted. “You’re in a diaper. Use it. And then I’ll get you all nice and snug in a dry one.” he taunted. Izuku came in and sat next to the two of you.

“Izuku, I need to go pee.” you said.

“Oh good, then you’ll be fine.” he looked relieved. “Go ahead and pee, pumpkin. We’ll change you.”

“No,” you protested.

“Yes,” Katsuki hauled you back against his chest. You tried to fight him off, but he used one arm to pin yours down to your side. Your legs kicked, but Izuku slid off the couch to kneel in front of you, holding them down.

“Now, Kacchan,” he said.

And Katsuki pressed on your stomach, right where the pressure was. You howled, trying to flee. But they held you tight. You sobbed, feeling your bladder give out, feeling your diaper expanding between your legs. You screamed, trying to get away from the evil sensation of Katsuki’s hand.

“Sh, sh, sh,” Izuku tried to soothe. “You’re okay, you’re okay.”

“I don’t want to, I don’t want to!”

“You’re going to be for a few days.” Katsuki said in your ear. “The diuretics will help us make sure that you’re producing like you should. You’re going to get a UTI.”

“And we’ll keep your sippy filled.” Izuku promised. You were a mess of snot and tears. He took you from Katsuki’s lap, carrying you towards the bathroom.
“Let’s have a nice warm bath, babes.” he seemed to be ignoring the fact that you were humiliated and devastated.

How had that plan not worked?

Chapter Text

You wouldn’t have liked the idea just a little while ago. But you were getting stir crazy in the house. There were only so many times that you could stack blocks, you thought. Denki had said that he had errands to run, and he needed you to go with him.

“Please can I wear jeans?” you begged. Denki hesitated.

“Honey, I think that your diapers are going to show through that. We don’t have any baggy jeans for you.”

“Please? I wanna look…” you trailed off, afraid that you were going to upset him, the way you had Katsuki.

“Well…” he sighed. “Go and get the pads that ‘Zuku bought for you.” you lit up, racing for him and throwing your arms around his waist.
“But you have got to be a big girl and tell me the moment you have to go potty, okay?” he warned. You wrinkled your nose at his language, but thought better of protesting out loud.

You skipped to the bathroom, grabbing a pair of your own underwear. It felt like forever since you’d been able to wear it. You put in one of the pads and pulled it up, grabbing a pair of jeans. There, you thought, no one would need to know. Besides, you were positive that you could make it work. You were good at paying attention.

You had to sit in the backseat of the car, but you didn’t mind. You were content to watch the scenery go by, pretending that you were riding the bus or something. Denki pulled in the grocery store. You were happy to push the cart, helping choose the fruit and vegetables for the week. You were even able to wheedle Denki into buying you some candy.

After loading the trunk, you were driven to the library. You stayed close to Denki, holding onto the back of his jacket while he returned books and checked out what Katsuki and Izuku had on their lists. You chewed on your lower lip.

Your eye was caught by the colorful kids section. You saw the bean bag chairs, puffy and inviting. You saw the pretty picture books, promising tales of princesses and talking animals and adventures with simple, clean endings.

“...Babes?” you snapped to attention, realizing that Denki had been speaking to you for a minute. You shook your head and looked at him.
“Are you okay?”

“Yeah. Yes. I’m fine. It’s fine.”

“Okay,” he glanced at the children’s section, and a light seemed to go off in his head. He took your hand, lacing your fingers together and giving it a squeeze. As you walked out of the library he bent to whisper in your ear.
“Do you need to go potty?”

“No,” you said a little too quickly.

“Are you sure you don’t want to go and try?”

“No!” you sighed. He nodded and set you back in the car. The next stop was a discount store. Denki thumbed through the towels thoughtfully, keeping up a train of thought.

“I know we all have our own assigned color. BUt maybe it would be easier if we just made things black or white? We could just do one big load of linens a week.” he was prattling on as you nodded along.

But next to the towels there was a display of tub toys. You drifted towards them, picking up one of the rubber ducks, You smiled at the bright blue eyes and the playful tilt of his head. You picked up a whale next, one that lit up as it floated and sprayed a fountain from the top of its head.

“Well that’s a fun looking guy, isn’t it?” Denki said softly in your ear. You almost jumped out of your skin. You quickly put the whale down. The blond picked it up and put it in the cart with the pile of towels. He thought again and grabbed a few of the rubber ducks, too.
“Now my baby can have some fun in the tub. We really should have thought of that sooner.”

You stood in line to pay, looking down at your shoes. As you helped Denki pick up the bags, he stopped you again.

“There’s a toilet right there.” he pointed.

“I can see, Denki!” you snarled. “Let it go.” he shrugged and you went to another shop.

This one was smaller, a dusty hardware store. There wasn’t much to look at, and your hand drifted towards your mouth, ready to pick at your lips. Denki caught your wrist and brought it down.

“No, my love, you’ll hurt yourself.” you blushed and looked down. As Denki was selecting things that Eijiro had put on the list, you realized that you had a need. But, you thought, it wasn’t too bad. You could just clench your muscles. If you didn’t think about it, it would be fine.

Your mind wandered as you held onto Denki’s jacket. Why was he taking so long? Why was this so hard? You wriggled in place, shifting your weight from foot to foot. As Denki went to walk down another aisle, you tugged at his jacket.

“Denki?”

“Mmmhmm?”

“I need to pee.”

“Oooh,” he looked around. “There’s no toilet in this shop, hon. There’s not one in any of the shops here.” they were all quaint little shops, highly specialized. You gulped and crossed your legs.
“Can you hold it?”

“Yes,” you mumbled.

He looked doubtful, but he didn’t hurry up, either. You were trying hard to keep yourself from doing a potty dance. You were gripping your shirt in both hands, wringing it as you waited. When the first trickle came, you whined. Denki gave you a sympathetic look.

“Oh, sweetheart.” he sighed. You couldn’t hold it back, couldn’t hide it. The pad was not good for big accidents, and you knew that. So you concentrated hard. You were able to pinch it off painfully. BUt looking down, you saw the wet spot at your crotch.
“Is that all?”

“No,” you admitted.

“You might as well finish,” he rubbed your back in small circles. “It’s gonna be okay.” you whined, your bladder happy to let go, that burning pain resolving. You were in tears as you felt the piss seeping down your pants legs, long wet streaks.
“Shh, shh.”

“I’m sorry!” you sobbed.

“It’s okay, it’s all right. You couldn’t help it.” he was taking off his jacket, wrapping it around your waist like that could do anything.
“Just stand here, I need to tell the shop keeper.”

“No!” you bawled. “He’ll know.”

“Well…” Denki hesitated. “You managed not to get any on the floor.” He took your hand and hustled you towards the counter, handing the basket of items he had collected to the shocked elderly man behind the register, apologizing profusely.

He knew. You knew he knew. It made you cry harder. Denki took you to the car, tucking you into the backset and buckling you in. He tried hard to settle you down as he drove home, glancing in the rearview mirror.

“Dammit,” Denki sighed, realizing that the others had come home. You couldn’t seem to stop crying, sitting in your soaking wet jeans. As he parked, the door opened, someone ready to help carry in bags.

Izuku was smiling, walking towards the backseat. But his face fell when he saw your upset. In a hurry, he opened the door, reaching in to unbuckle.

“What’s wrong? Are you sick? Are you hurt–oohhh,” he saw the mess you were. “Oh, baby, what happened?”

“I tried, I did, I tried.” you babbled. He hummed in agreement, lifting you out into the house. You left your soaked face in his neck, hiding your tears and embarrassment, even as Hanta and Eijiro were trying to ask what the problem was.

“Go help Denki get the groceries out.” he said instead, taking you to the bathroom. He managed to set you down, untying the jacket and taking off your top.
“Baby, love, darling, sweetheart. I know that you’re upset, I understand why. But I need you to calm down and tell me what happened.”

You were nearly hyperventilating as you tried to gather the words. Izuku took off your socks and stayed on his knees, hands on your waist as he waited for you. You ended in hiccups, speaking to him.

“Denki said that I could wear my pads.” you managed. “But Izuku, I had to pee.”

“Oh, I see.” he said solemnly. “Well this isn’t your fault, it’s Denki’s. He knows what’s supposed to happen.” he started the tub, pouring in bubble bath.
“Denki knows that you’re just a baby.”

“I am not, I am not, I am not!” you chanted.

“You need to settle, love.” he lifted you into the tub. The door cracked open, and Ejiro was dangling in a bag. Izuku took it, pulling out the rubber ducks and the whale. He put them in the water. You stopped crying, sniffling now and then as you pushed the whale and ducks. When the whale sprayed it’s fountain, you even giggled a little. Izuku had grabbed your body wash and wash cloth, washing your back and chest.

“Silly,” you said to one of the ducks as it bobbed towards you.

“How cute,” Izuku cooed. “Just as cute as you, huh?” he drained the tub and helped you stand, wrapping you in a towel and carrying you to his room.

“Someone had a hard outing.” Katsuki noted. He had a bottle of lotion in his hands. He poured some in his palm and lifted your arm, beginning to massage it in. You snuffled, looking at him with big, wet eyes. You barely noticed when Izuku put on a diaper and grabbed a nightie for you, complete with ruffles and lace.

“Come here, we’re gonna go cuddle.” Izuku said softly, picking you up.

“I said I was sorry.” Denki muttered.

“You know damn good and well she needs a diaper!” Hanta threw his hands up. “Now look, she’s a mess.”

“My jacket got wet.” he sighed.

“And that’s your fault.” Katsuki huffed at him. “You have to take it to the cleaner. You traumatized her!”

You ignored them, staying in Izuku lap. He sat with you on the couch, letting him cuddle you close. He rubbed your back, kissing your head now and then until you seemed fairly calm.

“We’re not gonna try that again, are we?” he asked softly. You shook your head, rubbing at your eye.
“Aw, baby, are you sleepy? You can close your eyes.” he encouraged. “Just take a little rest. You’ll feel better when you wake up for supper.”

Chapter Text

You didn’t complain about being put into the diaper for bedtime anymore. You weren’t sure how they managed to do it with you barely being awake. You were carried to the table every morning and set in your high chair. But one morning, Denki had a bright smile for you.

“I have a surprise for you, love!” he put cereal on your tray, without milk. “Eat up and then I can show you, okay?”

You were excited to hear that. A surprise from Denki? You were a little scared, after all that had happened to you down at the shopping mall. But if he was excited about something, then it had to be great. You ate your cereal with your fingers, ignoring the fact that typically a spoon was used, and ignored that the others had omelets on their plates. After all, you thought, you liked cereal better. You held your arms out to Eijiro when he made to lift you out.

“Come on, angel.” he murmured. “Let’s go and see what Denks has for you, hmm?”

He carried you, still in your onesie to your bedroom. You were curious and confused. How long had it been since you’d been in here? You slept with one of them. Your stuff was being kept in their rooms, since they chose what you wore.

“Ta da!” Denki said as he threw the door open. Your jaw dropped as you stared.

The room had been painted a soft shade of pink. There were soft rugs to lay on. There was a toy box, a book shelf, and even a filmy pink canopy that hung from the ceiling over a pile of cushions and stuffed animals. There were even fairy lights strung along the canopy, casting a glow that made you just want to climb right in.

“What is this?”

“A play room! Just for you.” Denki scooped you from Eijiro and took you to the pile of cushions, plopping you down. “I thought you’d like somewhere that wasn’t the living room to hang out and play.”

“I don’t need a play room.” you said slowly.

“Yes, you do.” Eijiro went to open your toy box. “Where else would we keep all these toys?”

“Why did you get me toys?”

“Because you need something to do all day.” Denki said smoothly. He opened a cupboard and proudly displayed a rack of dresses. You gasped and got off the cushions, heading for them. They were lovely dresses, you realized. Soft, silky dresses that were made in the style of the princesses you had seen in all the movies. You touched the yellow one, in awe. It must have taken Denki forever to sort this out.
“I knew that would get you.” he laughed.

“And it’s all mine?” you said softly.

“All for you.” he agreed.

“Denki!” you darted to him and stood on tip toe to hug him. He hummed, lifting you up to hug you, give you a little twirl.

“And you’ll be a very good girl and do what you’re asked?” he asked in your ear. You nodded. He kissed both your cheeks and set you down.
“Then have fun until it’s lunch time.”

He and Eijiro slipped away. You went to the toy box, pulling out a doll. You lifted her up, looking at her cloth face with the paint on smile. You admired her yarn hair and then went to the book case, grabbing a book and going to sit back in the cushion pile.

“There’s my little girl.” Izuku’s voice was warm. You looked up suddenly, surprised. How long had you been sitting there with your book, cuddling the doll?
“Are you enjoying yourself?”

“I’m fine.” you mumbled. You put down your items and went over to him, rubbing at your eyes.

“Oh?” he raised an eyebrow. “You seem awfully drowsy for someone who is fine.”

“‘M not.” you yawned. “I appreciate all this, but I don’t think I need it. A play room is for a kid, and I’m not a kid.”

“No?” he scooped you up. “Let’s get lunch and we can talk about it afterwards.”

You were silent as he parked you in your high chair again, a cut up sandwich put down. You ate silently, rubbing at your eyes again when you were done. Izuku unstrapped you and wordlessly took you to his room.

“Do you like your play room?” he asked as he laid you in bed. You were barely aware of the way he was unbuttoning your onesie, getting you into a fresh diaper and snapping you back in.

“It was so nice of Denki and he put in a lot of work.” you paused. “But… but Izuku, I don’t need it. I’m not a baby, and I don’t need it, and where will I sleep?”

“You sleep with one of us, remember?” he was turning down the blankets, tucking you in. He laid down next to you, on top of the blankets, his fingers tracing down your face.

“But it’s not forever. Until I seem better, remember? And don’t I seem better now?”

Izuku didn’t respond, playing with your hair instead. He twisted the ends around his fingers, then stroked your hair back. You snuggled closer to him, feeling him wind an arm around you.

“Right, ‘Zuzu? Not forever?” you yawned.

“We don’t need to worry about forever.” he said softly. “I think we only need to worry about you getting a nap.”

“Not a baby,” you said again.

“Okay, not a baby.” he allowed. “But everything that happened at the mall? I think that showed us that you might need a little more time like this. What do you think?”

“I’m not a baby.” you repeated. You stretched, your eyes feeling heavy.

“But you could be our baby.” he stressed the ‘our’. “And no one else needs to worry about it. Just us and you.” you made a humming sound.

“Why are you telling me to nap anyway?” you grumbled.

“Because Hanta is right and you get super cranky when you’re tired.” he laughed softly. You glared at him. He made shushing sounds and cuddled you closer to him.

“Not a baby, don’t need a nap.” you managed. Izuku nodded in agreement.

“Even big people need naps.” he said softly. He continued stroking your hair until he felt you dozing off, safe in his arms, snug in your onesie.

This was going smoother than he hoped.

Chapter Text

“Because we might want to sleep without another body in the bed.” Hanta said. You stared at the crib, back to him, and back to the crib.

“I thought the point was that you had to be able to check on me.” you shot back.

“And we can do that if you are in the room. We can drop the sides, see?” he demonstrated for you. You shook your head, backing away. You darted out of his room, towards the living room, through to the kitchen. Izuku looked at you and frowned, putting down the pan he was drying and holding his hands out to you.

“What’s wrong, love?” he asked, picking you up.

“I don’t need a crib.” you said emphatically. “I already don’t have my own bedroom.”

“No,” he agreed. “You have a lovely play room, don’t you?” he settled you on his hip. “There’s one in everyone’s rooms for you, so you can still choose who you want to sleep with.”

“Izuku, no,” you shoved against him.

“Baby, yes,” he shook his head. “This will make you so much more comfortable.”

“You don’t… you don’t want to cuddle with me anymore.” you accused. Izuku’s face fell and he hugged you tightly.

“No no no,” he swayed slightly. “Of course not. We love snuggling the baby. It’s just that sometimes we get hurt at work, or sometimes we’re extra tired and we’re going to need to stretch out a bunch.” he kissed your cheeks.
“It’s so the baby can get the best sleep.”

“I don’t like it.” you insisted.

“You will,” he promised. “You can pick out whatever blankets you want, or any kind of stuffed animals so you could have a buddy. And we can get a mobile to play pretty music…” Izuku prattled on as you stared at him. What was he not understanding?

“I am not sleeping in a crib,” you said firmly. “If I can’t sleep in bed with you, that’s fine. Then I will go back to sleeping in my room.”

“Not an option.” Izuku shook his head. “I understand that you’re upset. You can still choose what crib you sleep in. And it won’t be every night. Do you want to sit with me and we can pick out bedding?”

“No!” you snapped. “I already told you no. You don’t listen.” you squirmed until he put you down and stalked towards the living room. You did hate the fact that you were in a onesie and fuzzy socks, complete with a diaper. Still, you told yourself that maybe, just maybe they were getting the picture.

You plopped down on the couch, arms crossed. Hanta came out then, giving you a stern look.

“If you need to pout, you can take it to the corner. We don’t need that attitude.”

“I don’t need a crib!” you snarled.

Hanta sighed and put his hands under your armpits. You whined as he half walked, half dragged you to the corner. You were beginning to hate the corner where you were made to stand when they were tired of you. Anytime they thought you were throwing an attitude, they’d stick you here until they felt like you’d learned your lesson.

What lesson, you thought as you fisted at your eyes. You told yourself those tears were because you were so frustrated, and not because it hurt your feelings to be tucked into the corner like that. You felt time crawling before Izuku came to wrap his arms around your waist and pull you against him.

“Are you calmer?” he murmured. You nodded. You still weren’t going to sleep in the crib, but you could be calmer about it now. Izuku was satisfied as he reached between your legs and tapped your diaper.
“Dry, huh? All right, love, do you want to go to your play room, or do you want to sit in here?”

You sat in the living room, feeling a little withdrawn. As the others came home, you sought refuge in Eijiro’s lap. He was happy to have you there, cuddling and coddling you, letting you hide in the shelter of his arms.

“Can’t I sit with you for supper? Please, Eiji, please?” you knew that you meant to sit in the damn high chair, but there was no way you wanted to. Eijiro was the softest touch, you thought as he sat you in his lap, feeding you bites off his plate. It wasn’t as good as having your own real plate at the table, but better than those little plastic plates and having to eat with your fingers.

You spent the evening with him, too. Eijiro played with your hair and enjoyed when you pressed kisses to his cheekbones. He smirked at the others, gloating silently that you had chosen him to hang out with. And just when you started rubbing your eyes, he swept you up.

“Let’s get to bed, babes.”

“Okay,” you murmured. You refused good nights hugs and kisses to anyone else, particularly Hanta and Izuku. Hanta looked distressed, but Izuku only ruffled your hair and bid you good night.

You were laid out on Eijiro’s bed, changed into a fresh diaper and onesie. At least you’d get to sleep in his bed, you thought smugly. You should just stay in his room forever, you thought. He’d never think to have you sleep in a crib of all things.

The red headed man picked you up for cuddles and kisses. You wrapped yourself around his torso, relishing in the way he kept your weight. He'd lay down, you thought, and you’d cuddle on his chest and this whole thing could be forgotten.

You gasped when you realized that he was putting you down in that godforsaken crib. There was only plain white sheets and a plain throw blanket. He laid you down so carefully, like you were an actual fragile baby. You sat up and stood up, scowling at him as you held onto the side of the crib.

“Eijiro!”

“Shh, it’s night-night time.” he soothed, stroking your hair. “Let Eiji get ready for bed, and then I’m going to sleep, too.”

“I don’t want the crib!” you stomped your foot.

“I know it’s not super great now, but it’s really for the better.” he disappeared out of the room, presumably to the bathroom. You shouted, rattling the side of the crib. Denki
stepped into the room, looking concerned.

Maybe he’d rescue you. You held out your arms to him, hoping that he’d play into the cute, defenseless baby act. But he moved your hands from the rail and moved to lay you down, pulling the blanket over you.

“I don’t want this!” you shouted. “Let me up, Denki. I’m getting out of this stupid crib. I’m not a baby, I’m not a baby!” you chanted. He bent into the crib and kissed your forehead, stepping out.

With an irritated sound, you tried to throw yourself out of the crib. But it was too high to jump out of, and throwing yourself over the side was only going to mean you’d get hurt. You went to the sides, trying to find the latch or whatever it was they used to make the thing drop. But try as you might, you couldn’t seem to grasp it.

Eijiro came in, smelling like toothpaste. He moved your hands from the rail, brought them to his mouth for a kiss. You watched him, relaxing, thinking that you were finally going to be lifted out. Instead, he laid you back down, covering you over again.

“No!” you sat up.

“Good night, babes. I’ll get you in the morning, okay?” and he turned out the lights and actually laid in bed, his back to you. You stared in shock as your eyes adjusted. He was just going to sleep? Like this was fine and normal? Like nothing was wrong? You stood back up.

“Eiji! Eiji! Eijiro!” you shouted. He didn’t even stir. “Eiji, please! I don’t want to sleep here! Eiji!” you stomped your foot again. But Eijiro did not stir. You stared for another minute.
“Eijiro Kirishima! Get up!”

The red head didn’t lift his head. You let out a shriek of frustration, trying hard to find that latch. You didn’t see Eijiro getting up, you didn't see him sneaking out of the room. When he came back to stand in front of you, he caught your chin, thumbing away your tears.

“It’s late, and you’re tired.” he was pressing something to your mouth. You tried to shake him off, resit when you realized it was the stupid penis gag. Eijiro’s hands were gentle as he buckled it behind your head. Your hands went to pull it off, upset when you realized it wouldn’t budge. You howled, muffled as it was. He laid you back down, pulling the blanket around you once more.
“Good night, babes.”

And you were left silenced in the crib.

***

You stared at him for awhile in the darkness. You sniffled a few times, finding it slightly difficult to breathe with a stuffy nose and the gag. But Eijiro didn’t move. Eijiro didn’t even seem to notice you. But you must have fallen asleep. You were still asleep when someone bent over the crib and lifted you up, their head cradling the back of your head.

You stirred, snuffling against the pacifier. A hand patted your back, settling you right back down. Your body was limp against someone’s chest, even as you were carried out of the room. You didn’t stir until you were laid back down.

“How did you sleep, babes?” Denki’s voice, you felt him unsnapping your onesie. “You were pretty upset last night, huh? Did Eiji finally give you a binky to help you sleep?”

Your eyes popped open and you glared. You reached back behind your head, trying to undo the gag.

“No no no,” Hanta was speaking gently catching your hands. He held them in one hand, pressing down on your chest to keep you laying down. You growled, wriggling your hips, trying to sit up.

“Uh oh, someone’s fussy.” Izuku noted as he walked into the living room. You protested through your silicone mouthful, trying to wriggle off the couch. Denki worked quickly, snapping you back up and then reaching to pick you up.
“Did you not sleep good, babes? Eijiro said you were having a hard time.”

“She’s probably sick of that in her mouth.” Katsuki’s voice was rough from sleep. You gave him a sad look as he reached behind your head and undid the buckles. You reached for him, although that surprised even you.

“No more crib,” you whispered.

“I don’t think that’s up to you.” Katsuki booped you on the nose. “We make the rules.” he reminded you.
“But now we need to get you some breakfast.” he carried you to sit down in your high chair. This had not all what you had wanted.

Chapter Text

It didn’t usually work out this way. They tried to have at least two home with you at a time. That way someone could always keep an eye on you. You resented it when you first heard the reasoning. But, somewhere deep inside, you liked not having to be home alone. You liked knowing that someone could pay attention to you.

“We’ll have a good day, won’t we?” Denki took you out of your high chair. Everyone else was gathering their items, coming to kiss you on the head. You scowled at everyone, thought about refusing kisses. But you didn’t want to have to go to the time out corner, especially first thing in the morning.
“Just you and me, right?”

You were parked on Denki’s hip. You wrapped your arms around his neck, watching silently as he made a sippy cup. You scowled even harder. You could manage a regular glass! Or a water bottle, if they wanted to be jerks.

“Bluey,” you mumbled before you could think. Denki cooed and kissed your cheek.

“Yup! A special Bluey cup just for you, babes. Isn’t that cute? Do you like it?” you nodded to him, even though you wanted very much to shove yourself down. Denki carried you to the couch, settling you in his lap, your back to his chest.

You sipped from the cup. He held it for you, his other hand rubbing at your belly. It was easy to stretch your toes out. You relaxed against him, feeling him rubbing your tummy. The sippy was empty quickly, but he had turned on Bluey, and you were transfixed.

Denki bounced his knees gently as he texted on his phone, answered emails, and enjoyed the sensation of you in his lap. It wasn’t too long before he felt you squirming. He set his phone to the side and sat up straighter, putthing his hands on your hips.

“Something wrong, baby?” he purred in your ear.

“Gotta pee,” you mumbled. Denki hummed. You were relieved when he unsnapped your onesie. He reached for the tapes of your diaper and eased it open. You went to stand up, make your way to the toilet. But a soft pinch to your bottom ad you squealing, sitting back down.

“Go ahead.” he gave you a bounce.

“But-but the diaper is-is open.” you stammered. Denki spread his legs, opening yours. You whined, shaking your head.
“I can’t.”

“Then you better pee pee extra careful, huh?” he teased. “I know you’re just a silly baby, but you don’t need to make a big mess, do you? You’ll wet in that diaper very carefully.” he pressed at your belly.

You really didn’t need the help. You gasped, focusing hard on only letting out a tiny bit of piss. Denki groaned from behind you, pressing his head against yours.

“Oh, look at you,” he praised. “Doing just what you’re told. Wetting in that diaper, pee-peeing yourself nice and neat. Just like I said, huh?” the way he was talking set your body on fire. You moaned softly, from the hot shame and from the other warmth growing between your legs, so naughty and so tingly.

“Stop,” you whined.

“No,” he mocked in the same tone. “You just worry about emptying yourself, that little pussy is getting so wet. You like this. You can tell me to stop, but you like it, don’t you?”

You sighed when you were emptied out, collapsing against him. Denki nipped at your neck, listening to you squeal. He licked the reddened spots. His fingers went to your sopping wet cunt. He opened your pussy lips with one hand, the other finding your clit to rub tight little circles. You sucked in a breath.

“I know you like that. Messy messy little thing. Let’s get all the cum out of you, huh? And then I’ll give you a fresh diaper. I don’t want to put one on you if you’re just gonna make another mess.” he gave the smallest smack to your exposed pussy.

“Fuck!” you wheezed.

“Naughty,” Denki scolded. “I’ll have to give you a binky if you can’t use your nice words.” he warned. But it didn’t matter. You howled as you came. He smiled against your skin, watching you squirt into the soaking diaper.

You watched through half lidded eyes as Denki maneuvered you around. He moved the wet diaper to the side and laid you on the floor. He wiped you up, put a little rash cream at some areas that were looking a little sore. He buttoned you into the onesie, aware of how you fisted at your eyes.

“Long day already?” he asked as he picked you up. “We can cuddle.” he sat you down, turning you to face him. He tickled your back as he sat with you, feeling you go limp and still in his arms.

It was a little bit early for nap, he thought. But then again, you hadn’t really slept all that well. It couldn’t hurt. He stood up slowly, his hand cradling the back of your head. He could put you down in your crib, you’d sleep for hours, and wake up in a good mood. Flawless plan, he thought to himself.

So Denki laid you in the crib in his and Hanta’s room. He pulled a blanket up to your chin and stroked your hair. You remained asleep, cozy in the place he’d put you. Why did Eijiro think this was so hard, he wondered. He’d just have to show him how it was done! But Denki wasn’t to the living room when he heard your sudden cry. He paused for a moment, listening to the way you were shouting even louder. He hurried back to you.

“Baby, baby, what?” he asked, lifting you out of the crib. You clung to him, and even him swaying and rubbing your back took awhile to get you to settle. Maybe he shouldn’t have left so suddenly, Denki thought. He laid you back down, covered you over. You were immediately kicking the blanket off, starting to scream again.
“Can you use your big girl words and tell me what’s wrong?” he begged. You shook your head, rubbing at your eyes, smearing tears everywhere.

That was fair, when Denki thought about it. He couldn’t decide you were a baby and had to pee in a diaper and then bug you to act like a big girl when it worked for him. He picked you back up, shocked when you arched your back, continuing to scream.

“No, no, no!” you howled when he moved like he might lay you back down. Denki paused to look at you, perplexed. Your fingers pinched at his collarbone. You were nearly hysterical, trembling as you screamed.

“Is it the crib? Babes…” he sighed. “You’ve been told.”

You didn’t seem to car, little fists balled up, pounding at him. Denki bounced you, going to the night stand and pulling out another of the penis gags. He tried to coax it towards your mouth. You threw your head back, nearly launching out of his arms.

“Fine then,” he stiffened his spine. “You get the treatment you earn.” he warned. He put you in the crib, firmly but gently. You stared after him for a few seconds, breath hitching as he walked out of the room. You were demanding attention, he knew it. He’d take it away and then you’d lay your crabby ass down and sleep.

But you were screaming when he went to the living room. You kept screaming as he went to the kitchen, hoping a mug of tea would help calm his nerves. But once it was done, he didn’t want to drink it. You continued to scream, and he could hear the roughness that was chewing at the edges of your voice.

“Please stop.” Denki sounded exhausted himself as he sat down at the edge of his bed. “Come on, baby, you are so tired. Lay yourself down, you’ll feel better.” you didn’t even listen to him. Your whole face was red and you were holding the railing of the crib. He could hear the gasps at the end of each screech. He watched your chest heaving, growing in concern as you were gagging at the end of every scream.

What was he going to do? You were obviously gonna get sick. And they’d never let him forget that. Denki grabbed the gag again, trying to put it in your mouth. But as soon as it slid the dick towards the back of your mouth, you gagged violently.

“Enough!” he snapped his fingers. You froze, barely breathing. “This is not okay. Behaving this way tells me that you’re tired. So lay down.”

“No!” you screamed, blood curdling, bouncing on the crib mattress. Denki look at you and rubbed his hand down his face. He blew out a breath and picked you up. You dissolved into hiccups, clearly still overworked.

“No more screaming,” he whispered in your ear. “You’re okay. Shh, shh, shhh.” he bounced his knees, watching you try and settle yourself down. You rested your head on his shoulder, giving little coughs now and then. Denki laid down in his bed, laying you tucked into his side. You clutched him, rubbing your face into his shirt.
“You’re going to make yourself sick, sweetheart.”

Denki stayed with you until you were asleep. He thought about trying to transfer you to the crib. But he honestly did not think he could stand another round of screaming. His head was pounding and his ears were ringing.

He heard the door open, wanting to cry himself. Hanta stepped into the room, clearly confused. Denki put his finger to his lips and shook his head. Hanta hurried to the bed, laying down next to him, an arm going over you.

“I just spent forty five minutes trying to get her to go to sleep.” he said in a tortured whisper.

“The point was she sleeps in the crib.” Hanta whispered back, amused. Denki looked back, eyes narrowed, sneering at the dark haired man.

“She screamed the whole time! Thank God we have a house and not an apartment. They would have thought I was killing her, and I don’t know how to explain. Sorry my sexy ass roommate acts like a baby sometimes and she doesn’t feel like napping?”

“Fair point.” Hanta snorted. He stroked your hair back from your face, taking in your swollen eyelids and puffy cheeks. You didn’t stir. Denki rubbed his eyes. Hanta leaned over and kissed you on the forehead and Denki on the lips.
“You look like you need a nap, too. We’ll have to figure something out for this crib thing, or we’ll never sleep again.”

“Yes, we would.” Denki shook his head. “It would just always be with a baby sprawled across us. Which isn’t the worst thing.”

“That’s not what you said when you wanted to ride my cock and she was laid out all over me.” Hanta raised an eyebrow. Denki huffed, adjusting you in his arms. Whatever, he thought, he’d take a nap with you and they’d all figure out the crib thing together.

“No, no wriggling.” Izuku put his hand on your thigh. “I’m almost done, sweetie.” you felt a diaper being taped around your hips. You mumbled something unclear. He hummed at you in response, snapping your onesie back up.
“I heard you had a hard time napping.”

You didn’t respond, refused to meet his eye as he lifted you up. He carried you to the living room, where Denki was sitting on the couch. When the others had come home to you napping on him, they had been surprised. And in quiet tones, Denki explained your screaming fit.

“Here, babes.” Hanta brought a cup of hot tea. You sipped carefully, enjoying the relief it brought your sore throat. Everyone was quiet, and you hoped if you looked occupied, they’d forget about what had happened.

“You’re spoiled.” Katsuki announced. You looked at him, careful not to scowl. That would only prove his point.
“We give you anything you want.”

“Do not,” you shook your head.

“Screaming and carrying on through naptime is not acceptable behavior. You’re lucky it was Sparky and not me.” you cringed away, trying to make yourself smaller in the couch cushions. “Matter of fact, stand up.”

“No,” you said softly.

“Do not make me go over there and get you.” he warned, glowering from his spot on his chair. You whined and set your mostly empty cup down. You shuffled over to him, wringing your hands. Katsuki patted his knee, and you didn’t have to ask what he wanted. You draped yourself over his knee, clinging to his pant leg.

“Kacchan,” Izuku began. “Are you sure that–?”

“Can it,” he snapped. “Unless you want to spend every nap and bedtime with a screaming banshee.” Izuku closed his mouth. Any hope of rescue was gone. Your onesie was unsnapped with a rough hand, leaving you gasping. Katsuki kept a hand on the small of your back.

For all that the diaper was so puffy, it didn’t provide any protection from his wide hand clapping against your bottom. You whined as he focused on your sit spots. After he had attacked each of your cheeks, he was undoing the tapes, opening the diaper.

“No!” you whined.

“Yes,” he snapped. And his bare hand was against your skin, somehow even harder. Your skin was burning and you yelped, tears falling down your face. You couldn’t keep from sobbing as Katsuki continued.

The rest of the house was quiet, watching your humiliation. After a few minutes, although they felt like an eternity, Katsuki finally stopped. He lifted your diaper up your bottom and held it there. You were confused, blubbering still, until you felt the wet heat coming from between your legs. You moaned, face hot from embarrassment.

“Aww, she couldn’t keep keep her little panties dry.” Hanta said in mock concern. “Wetting herself because of a spanking. Don’t worry, baby girl. We’ll get you in a dry diaper.” you howled, hanging your head. Eijiro came to remove you from Katsuki lap, leaving the wet diaper behind.

“Don’t cry,” he soothed. “You learned your lesson, didn’t you, honey?” he laid you on the change pad, wiping you with the warm wipes. You closed your eyes tightly as he lifted your legs, ankles in one hand, and put a dry diaper down.
“Here we go, some fresh padding. That’s better, isn’t it?” he sat you up and worked the onesie off you.

“I want clothes!” you demanded.

“Hush,” he stood up, cuddling you to his chest and sat down on the couch. Izuku handed him something. The material was in your favorite color, catching your attention. Eijiro opened the material, revealing the softest, fluffiest blanket you ever saw. He draped it around you, the cloud soft fabric calming you.

“There you go,” Izuku said softly, rubbing your back. “Don’t cry, baby. You earned the discipline, you know better.” even when he was scolding you, he was being sweet. You buried your face in Eijiro’s neck, feeling like you didn’t have a friend in the world. Eijiro rocked back and forth a bit, hoping to settle you.

“So hard to be a baby.” he sighed. “You’re trying so hard.”

Your throat was still sore. Your fingers came to pick at your lip, and Eijiro took your hand away, kissing your fingers and holding your hand until you were calm. After you had finished crying, he was given the Bluey sippy cup, filled with warm tea.

“Drink this, love.” he kissed your temple, watching you sip. You stay in his lap, content in your blanket.

You were meek and quiet the rest of the night. Izuku thought that you’d had enough of restraints. You spent the dinner in his lap, being fed bites off his plate. In between, you let your fingers trace around his shirt, happy with your blanket.

“Come on, baby. We’re going to bed early. Let’s go potty.” Denki emptied his plate. He carried you to the bathroom, standing you in the tub. You covered your face with your hands, pissing easily into your diaper. It shocked you that this was easy, without you having to try and force it, or even think too hard.

Denki changed you again, putting on a layer of rash cream. He carried you to the room he shared with Hanta, pressing the dick gag into your mouth. You gave him pitiful looks as he strapped it behind your head.

“That will keep your mouth busy, won’t it?” he kissed your head. “We can have a cuddle in bed to help you fall asleep. And then I’ll put you in the crib, okay?” you nodded sadly. Denki kept your blanket over you as he laid in bed, letting you rest on his chest.

It wasn’t until later you felt yourself being moved again. You stirred, flopping against Hanta. He soothed you and laid you in the crib. But it was warm this time, and you had your blanket. It was just as comfortable to roll over and fall back into sleep as it was to scream.

“Finally,” Denki grumbled. “I get you all to myself.”

“You feeling neglected?” Hanta raised an eyebrow. “You needed my attention all to yourself? Feeling jealous of the baby?” he crawled onto the bed, reaching for his lover. Denki didn’t speak, only pressed his lips to Hanta, finally getting what he needed. And you remained still and asleep in your crib.

Chapter Text

Your head ached when you opened your eyes. You whimpered in your crib, pulling the blanket they had given you up higher on your body. You weren’t sure exactly when the blanket had become a necessity to you.

They gave it to you whenever they put you to bed, or for nap. They would drape it around you when you sat with them to cuddle. If you were sitting on the floor, watching television or reading a book, they would wind the blanket around you.

Somewhere along the way, it started to feel strange if you didn’t have your blanket for those times. Even when Eijiro declared it filthy (when you had only spilled a TINY bit of apple juice on it!) and popped it in the washer, you had felt strange. He tried to coax you into a nap, but you refused, saying you weren’t tired.

You were tired, but you wouldn’t say that out loud. You just didn’t want to sleep without your blanket. You dodged Eijiro the next few times he was dropping heavy hints about naptime. Finally, the light bulb seemed to go off for him.

“Aw, baby.” he cooed, picking you up. “Blanket will be done by the time you wake up. And then you can watch a tv show and cuddle. How’s that? I’ll even let you pick the show.” he tempted. You nodded and let him take you to his room.
“Know what? I think you can nap in my bed, not the crib.”

You perked up at that. There was no doubt you liked sleeping in their beds. Eijiro chuckled and laid you down, settling you in. You wrapped your arms around one of his king size pillows, falling asleep easily.

When Eijiro came back in to wake you up, he had your blanket, warm from the dryer in his hands. He gave it to you, smiling as you buried your face in it, not protesting the clean diaper at all.

It was this attachment that had lead to them getting a towel warmer. And it was nice to have a warm towel out of the shower, that was true. But you liked having a warm blanket to be tucked in with at night even more. It was one of the only ways they could get you into the crib without a temper tantrum. And fewer temper tantrums meant that you were less likely to get a spanking from Katsuki. Everyone won!

But today, you weren’t thinking about that. You were thinking of the pain in your head, the raw sensation in your throat. You rolled over, curling as tightly as you could under the blanket. You had just fallen back asleep when someone was in the room. The blanket was tugged down, Izuku smiling.

“Is it hide the baby day?” he teased. You shook your head slowly, afraid your skull would crack open if you did too much. He frowned and reached for you. His lips pressed carefully against your forehead.
“Oh, babes. You’re not feeling good, are you?” you shook your head again, nestling against him. Izuku made a sympathetic sound, grabbing your blanket and carrying you to the living room.

“What’s the matter with her?” Katsuki grunted.

“She’s got a fever and said she doesn’t feel good.” Izuku shifted you. You whined, clinging to him.
“And I think that’s making her extra moody.”

“Brat is always moody.” Katsuki held his hands out. “Give her here, go and make something for her to eat.”

“Not hungry.” you rasped, feeling like you were speaking through rusty nails. Katsuki winced and tucked your blanket around you. You dozed against him, hot face on his shoulder, while the others moved around you.

“Here, baby.” Denki said gently. “Some juice in your Bluey cup.”

You smiled to see the Bluey cup. You couldn’t explain why you liked it so much. But the orange juice inside stung when you drank it, and you shoved it away. Katsuki sighed and rubbed your back, handing it back over.

“Let me change her.” Izuku said, taking you and laying you out on the floor. You wanted to protest, but felt too weak to do anything but flop there. You didn’t even blush as he rubbed a little rash cream on you.
“Fuzzy jammies today, huh, baby?”

“The ones with the feet?” Hanta perked up. Izuku nodded and the dark haired man was off in a flash. You stared after him, wondering if your fever was causing you to hallucinate. Instead, Hanta was almost giddy when he returned. He handed off a pair of pajamas to Izuku.

They did have the feet to them, you noted. Also a hood, of all things. You couldn’t quite make out what it was as Izuku dressed you. He zipped it up and kissed your nose, sitting you up and pulling up the hood.

“You’re a unicorn!” Hanta laughed. It would have elicited a response if you didn’t feel so miserable. He scooped you up and sat with you on the couch.
“At least we all have the day off today so no one is stuck.”

The Bluey cup returned, this time with warm tea. You sipped it carefully. You were grateful for the relief it gave, but frowned when Izuku approached you with a pill.

“No,” you managed.

“Baby, you have a fever. You’ll feel better.”

“No!” you squeaked, regretting it. You burrowed into Hanta. Even though you could tell he wanted you to take the medicine, too, he still continued to cuddle you. Izuku disappeared, but returned with a little syringe full of red liquid. You began to shake your head.

“You’ve taken medicine before.” Denki frowned. “What’s different this time, babes?” you didn’t respond, wrapping your arms around Hanta. They seemed content enough to leave you in his lap as you drifted off, snuggled in the fuzzy pajamas and your blanket. You kept one hand wrapped in the blanket even in sleep, as though you were afraid someone was going to come and snatch it away.

After you had had a fitful sleep, whimpering and coughing as you did, Izuku came to take you away. He carried you to the bathroom, where he’d already drawn a warm bath. There were bubbles, you noted, and the scent of lavender filled the bathroom.

“I don’t feel good.” you managed to mutter to Izuku. He nodded and kissed you, holding you as he stripped you down. The blanket was placed into the towel warmer, and Izuku set you down into the bubble bath.

“Have a soak,” he said gently as he took off his own clothes. “My Mom always gave me a bath when I didn’t feel good.” you liked the thought of Inko bathing a tiny Izuku. The thought made you smile. You almost missed the fact that he got into the tub behind you, settling you between his legs.

“Can take a bath by myself.” you managed. He nodded indulgently and reached painfully around you to get a washcloth wet under a cold tap. He folded it and placed it against your forehead, letting you lean against him.

You did feel better in the tub, you thought. You played a bit with the bubbles, feeling too sick to do much else. After awhile, Izuku got you out and dried you off. He diapered you as carefully as ever, and wrapped you in the warmed blanket.

You wondered why, but didn’t question it. Wasn’t he going to put you back in the pajamas? But the blanket was warm enough, anyway, and it hurt your head to think too much. You coughed a bit, soothed by his hand between your shoulder blades.

When Izuku sat, he kept your chest to his chest. There was something about the way he was doing it, something that you didn’t like. Still, thinking was difficult, so you shut your eyes, enjoying feeling him rocking with you ever so slightly, kissing your forehead, sighing at your fever.

Before when you were sick, you’d dry swallow something over the counter and shuffle to your room to sleep it off. You preferred being by yourself when you weren’t well. Denki was the total opposite, you remembered. He’d dramatically sniffle or cough, turning his bright eyes to anyone around when he asked for tea, or some bubbly soda, or crackers, or a back rub, or a cuddle. You were always happy to give it to him, even though you never asked for the same.

Izuku was tickling your back, dragging his finger tips up and down it, drawing shapes. It was hypnotic, and you were zoned out as he did it, feeling boneless. You didn’t protest when he laid you in his lap, belly down. You thought he wanted to keep rubbing your back. You realized something was amiss when he was undoing the tapes on your diaper. You went to lift your head until his hand snaked up your back, to the back of your head. He rubbed your scalp. You moaned softly, feeling some of the pain abating.

“My poor baby,” he whispered. “Not feeling good at all, huh?” you hugged your blanket under you. It was then that you felt it.

“No, no, no.” Eijiro came to pin down your legs while Izuku had your arms. “Don’t jostle, babes. It’s only for two minutes.”

“Stop!” you cried out, tears in your eyes from the sudden intrusion and the pain of speaking. “Stop it!”

“We need to see how high your fever is.” Izuku said in such a reasonable voice, you almost felt silly for protesting.

“Under my tongue!?” you managed, craning your neck to glare at him. He did look a little sorry. Katsuki, though, just snickered as he continued to put the lubed tip of the thermometer in your ass. He patted one cheek, ignoring your grumble.

“This is much more accurate.” he told you. You had no choice but to lay there in Izuku’s lap. He at least did let his thumbs rub your skin, trying to give you some measure of comfort. It didn’t stop you from crying, even though that hurt, too. Eijiro kept his grip on your legs, and you didn’t bother to look at him.
“One oh two. You’re a sick girl, all right.”

“No wonder you’re so ornery.” Denki noted. He had come with a popsicle, offering it out to you. You should have wondered why Izuku was still holding your legs. But the popsicle was your very favorite flavor and you did like how it felt on your sore throat.

You let out a high cry when you felt something else pressing at your ass. You tried desperately to flail. Izuku and Eijiro kept their grip on you. Denki cupped your face, trying to calm and distract you.

“You wouldn’t take the pills or the syrup.” Katsuki said matter of factly. “Don’t know what else you expected, brat. You have a fever, you’re sick. This will make it better. We make the choices, and we decided you needed meds.”

“Stop,” you whispered brokenly. “Stop.”

“Pipe down, I’m almost done.” it felt like your puckered hole was sucking up the suppository. Katsuki held your asscheeks together for a moment or two afterwards. He fixed your diaper and moved. Izuku and Eijiro let go too.

You scrambled away from them, feeling slightly dizzy. Whether or not that was because you were sick or couldn’t believe what had just happened, you weren’t sure. You snatched your blanket and darted for Hanta, who was sitting alone in the oversized chair.

“Poor baby,” he said gently. “Come to Daddy.” everyone froze, looking at you.

“Daddy,” you agreed, settling down in his lap. He took the popsicle from Denki, holding it for you so you could take tiny bits and sucks from it. You didn’t even finish half of it before you were fisting your eyes.

Hanta wiped your face with a warm wipe and let you drape yourself over him. Your headache wasn’t as bad, and you knew your fever was coming down. Still, you thought.
You didn’t even want to look at them!

Chapter Text

You woke a little bit later, your headache back. You whimpered, trying to burrow into Hanta. He hummed and rubbed your back, pulling you back a little bit. He pressed his lips to your forehead and sighed.

“Fever is high again.” he reached for the sippy cup, this time full of water and offered it to you. You sipped and shook your head, shoving it aside. Hanta palmed your ass, you realized he was diaper checking.

“Baby needs some more meds?” Katsuki asked. You looked at him and tried to shrink away.
“Oh? Don’t want another pill in your cute little ass? Maybe you’ll take the liquid meds?”

“I have a popsicle for when it’s done.” Denki tempted. Reluctantly, you opened your mouth, letting Katsuki squirt in the meds. You shuddered at the taste, grateful for the popsicle that was offered to you then.

You sucked at it, letting the taste wash away the gross medicine taste. The popsicle did help your sore throat, at least. When it was all gone, Denki took you into his lap. It was nice, you thought, to snuggle and not to have to worry about anything. He kept coaxing the sippy cup into your mouth. You’d drink a little until your throat ached and then push it away.

When it was dinner time, you realized that Katsuki had made chicken soup. He carefully brought out a bowl. Denki turned you in his lap to face Katsuki. There was a look of concern on his face as he fed you bite by bite. It was delicious, but it hurt like hell to swallow. You managed half the bowl and shook your head, leaning into Denki.

“Poor baby,” Katsuki’s voice was soft and loving. It sent a thrill up you to realize you were the only one he talked to that way. You blinked slowly at him, feeling exhausted. He stroked your hair back and pressed the back of his hand to your forehead. You leaned into the touch, sighing at his cool skin.
“I’m sorry you don’t feel good.”

“The suppositories worked better for her fever.” Denki sighed. You whined and shook your head again. Izuku came with a spoonful of honey then and you smiled, swallowing it down, hoping it would give you some relief.

No one said anything else to you, letting you rest on Denki. They talked quietly, ate their own soup, and watched television. You dozed a bit until someone was lifting you up. You fussed, barely opening your eyes.

“I know, Daddy’s so mean.” Hanta cooed. “Baby was so comfortable. Come on, my love. We’ll get a dry butt and we can cuddle in the big bed.” that stopped your grumbling. Anything to be out of the crib.

And Daddy even grabbed the blanket from the crib. He handed it to you as he laid you in bed. You rubbed your cheek against the material, close to sleep again as he undid your onesie and diaper. You almost fell back asleep when you felt something pressing up your ass again.

“No!” you squawked, trying to worm away. Hanta did look sorry as he put your legs on his shoulders, his hands trying to hold your buttcheeks together.

“You know you’ll feel better. I’m sorry, baby, I am. But your fever is high and you need to sleep. The liquid isn’t helping.” you glared at him. They told you that it was one or the other! And they had gone back on that. You were crying when he lowered your legs into a clean diaper and taped it up.
“Oh honey honey, don’t cry. It’s okay. Shh, shh.”

But you were sick and tired and outraged. No way were you going to be quiet. You sobbed out your indignation and anger. Hanta kept trying to shush you. After a few minutes, he was shoved aside. Katsuki scooped you up.

“Enough of that,” he grabbed your blanket. “We’ll go to my room. I know, I know. Hanta gave you medicine for your illness. How very cruel of him.” but he was speaking sweetly, even if he was being sarcastic.

“Give me,” Izuku demanded, sitting up in the bed he shared with Katsuki. He handed you over, with the blanket. You snuggled into his lap, your arms around his neck. Izuku rubbed your back and rocked a little bit. It was easy for you to calm down.

***

“The doctor?!” you rasped. “But… I…”

“Sweetheart, your throat is on fire.” Izuku said grimly.

“But.. My… the…” you fumbled, unsure what to say.

“You can wear one of the incontinence pads.” he said kindly. He went to his dresser and pulled out sweats and one of Kacchan’s old shirts. He had your underwear, looking foreign to you now, since you’d spent so long in diapers.

But you were too weak to argue. He took off your diaper, wiped you clean and pulled on the panties. Once they were around your hips, he pulled up the sweats and the shirt. You kept looking at your blanket as he put on socks and shoes for you.

“I know, you want to take blankey, don’t you? I’m sorry, honey.” he helped you stand up on wobbly legs and put a jacket around you. You followed him out to the car, let him buckle you into the front seat this time.

The drive to the urgent care was quick, and no one seemed to care that you leaned against him in the waiting room. You were called back quickly, clinging to Izuku’s hand as he walked you back. He spoke for you to the nurse, describing your symptoms.

“Poor thing,” she clicked her tongue as she put a thermometer in your ear and a blood pressure cuff around your arm. You remained still, locking eyes with Izuku. She said the doctor would be right in. You wanted to leap off the table and run to Izuku. Instead, he got out of the chair and came to you, rubbing your back.

“You’re okay.” he whispered. “I know, it’s a lot all at once. And you don’t have blankey or anything. Just me.”

“You’re still good.” you mumbled. He smiled and rubbed your back. But once the doctor came in, he had to step away and sit back down. The doctor looked you over, frowning when he peered down your throat.

“That’s strep.” he muttered, going to type into his computer. “I’ll prescribe amoxicillin. We could also give you a steroid shot if you’re in a lot of pain.” cold sweat broke across your forehead.

“Where?” you choked out.

“In your bottom.” he shrugged. Your eyes widened. No way, you thought, he’d see the pad, he’d know, he’d know! You shook your head. Izuku jumped in.

“She’s a little anxious around needles.” he said smoothly. “If the amoxicillin doesn’t clear things up, we’ll talk to her PCP.” the doctor nodded and said the script was sent. Izuku held your hand as he walked you back out to the car.

You looked like a regular couple to anyone else.

He went into the pharmacy, leaving you in the car. But when he came back, he had his secret smile, the one that made you smile back. He handed you a plastic bag. Carefully you opened it and gave a surprised little cry, ragged as it was.

“A puppy!” he had found a stuffed puppy, the perfect size and amount of stuffing to squeeze.

“Thought you needed a friend.” he smiled as he started the car, ready to drive you home.

Chapter Text

You itched. That was the only way to describe it. You itched and it felt like your ass and vagina were covered in scales. It had started last night at some point, you thought. When Eijiro had changed your diaper before tucking you into the crib in his room.

You didn’t love it, that was for sure. But you had your blanket and your puppy to sleep with, and those helped. At some point, you stirred, feeling heat under your diaper. But it was kind of warm in his room, so maybe that was it? Either way, you were able to sleep through it, so it couldn’t have been that big of a deal.

Except it was.

When you woke in the morning, you were itchy as hell. You groaned when you sat up, squirming. Eijiro raised his head and yawned, smiling. But once he saw the look on your face, he frowned.

“What’s wrong, babes?”

“I’m itchy.” you hissed. His eyebrows went up. You could hear the others stirring. Someone was in the kitchen. Eijiro looked confused.

“I didn’t use any new soaps or detergent. Those aren’t new pajamas. Is a tag rubbing at you, lovey?”

“No, I mean…” you blushed furiously. “My–my diaper area.”

“Oooh,” the light clicked on. “You probably have a little rash baby. Let’s get that taken care of so we can eat breakfast.”

Eijiro picked you up. You yelped when he palmed your bottom, making him pause. He adjusted his grip so he was holding you around the waist. Katsuki was parked in the living room with a cup of coffee, ready to watch television. He look interested when Eijiro laid you down on a blanket on the floor.

“Jammies come off.” he hummed, taking them off you. He paused, looking at your thighs. Around the leg holes of the diaper there was an angry looking red rash. You whined when he brushed his fingers against it.
“That’s not great.” he muttered, undoing the tapes. “Oh, baby, I am so sorry.” he gasped.

“What’s wrong?” Izuku asked, stepping it, a dishtowel over his shoulder. “Holy shit.”

“It itches!” you whined again, reaching to give a scratch now that the diaper was off. Eijiro caught your hands before you could.

“No no no, that skin is much too delicate.”

“What the hell happened?” Katsuki demanded. The three of them staring at your crotch was making you embarrassed. You squirmed from the discomfort of it all. Eijiro rubbed your hands, hoping to soothe you.

“It itches and it hurts!” you declared, arching up off the mat.

“I know, we’ll fix it.” Izuku hurried to calm you. Hanta stepped in, rubbing the sleep from his eyes.

“Oh? What game is this?” he asked, leering.

“Daddy!” you shouted. There was something in your tone that made him hurry to your side. He hissed when he saw your groin. Carefully, delicately, he examined it, whispering apologies when it made you cry out.

“This doesn’t look just like diaper rash.” Izuku declared. “She’s had that before. Was there anything new?”

“Denks brought diapers at the store.” Hanta said suddenly. “He said that they were out of her normal kind, so he grabbed another brand. To tide her over.”

“Fucking idiot!” Katsuki growled. Said idiot came stumbling in. He froze when he saw everyone hunched over you.

“What’s going on?” he asked slowly.

“You really couldn’t find the right diapers? You can’t even do that right?” Katsuki snarled. “Go ahead, look at what you’ve done to the baby.”

“Oh God.” he gasped. “Baby, I am so so sorry.” he looked near tears. You squirmed again, that burning itch driving you nuts.

“Okay,” Izuku clapped his hands. “Denki, go and get the baking soda and a bowl of water for me. Kats, go and get a bunch of towels and some of the bed pads we used to use. Ei, will you please go and get her breakfast? Han, hon, will you go and get those mitts?”

“I don’t need those!” you whined out.

“Afraid so, sweet pea.” Izuku did look sorry. “I can’t have you tearing it up. You’ll immediately get an infection.”

“Please!” you begged. Izuku ignored it, although he did wipe at your tears as the others bustled around. Before you could say anything, the floor was set with a few bed pads, along with some old towels, and you were plopped down on them.

Denki returned with the bowl of water and baking soda. Izuku added the baking soda to the water until it was a paste. Wordlessly, he spread it on your rash, even as you sniffled. You were sat up, and the mitts were locked onto your hands. You were sitting on the floor, naked. Before you could protest, Eijiro sat down with your breakfast, perfectly content to feed you bite by bite.

“I am so sorry.” Denki said again before he went to get ready for work. He kissed both your cheeks. “I’ll bring you home a surprise, okay?”

You shrugged as he left. You wanted, you thought, your blanket. But when you had asked, Izuku said you’d be too likely to get it messy. You were waiting for him to get another diaper for you. Instead, he left you naked on the nest of padding and towels.

“But…” you began.

“Air is the best thing for you right now, love.” he shook his head. “And if you wet on the floor, that’s what all the towels and the pads are for. Everything is fine.”

“Can I have puppy?” you asked, feeling sullen. He looked regretful and shook his head again.

“Sorry, baby.” you couldn’t color either, not with the mitts. You felt tears in your eyes, felt yourself getting worked up. Strange, you thought. You couldn’t exactly pin point what the problem was. Everything was just–too much.

“The hell?” Katsuki rushed to the living room when he heard you howl. “What is her problem?”

“She’s having a meltdown.” Izuku said softly. He stayed kneeling next to you on the padding as you sobbed. He tried to reach for you, but you threw him away from you violently. They watched you for a moment.

“What do we do?”

“Daddy!” you cried, reaching out your hands. Both of them looked at you, confused.

“Hanta went to work, you know that.”

“No,” you sobbed, reaching for him. “Daddy.”

“Okay, okay.” Izuku grabbed a towel, putting it in his lap and picking you up. “I know, you feel like shit. But you gotta calm down.” he let you nestle into him, rubbing your back. It wasn’t long until you calmed down.

“What was that about?” Katsuki asked, arms crossed. You shrugged and shook your head. Katsuki sat down next to you, rubbing your back. When you were limp and wrung out. He and Izuku exchanged a look.

“I think you need a nap, baby doll.”

You were laid back down, an old blanket covering you. You were tired, wrung out from all that fuss. You fell asleep there, not even realizing when you piss, soaking some of the towels and pads beneath you.

Izuku moved carefully, transferring you to a dry patch and taking away all the wet things. Lucky for him you were out cold, he thought. He was sure you’d be better after a bath and a day of airing out.

They’d just have to deal with you being grumpy until then.

Chapter Text

But a day of air drying did help. And Izuku had somehow come up a few cloth diapers. He pinned one on you for bedtime, pulling the curious looking cover over it. And he was up to changing you once during the night, keeping you dry.

The next day, you were left home alone with Eijiro. And even though your skin only had one or two patches of pink, he insisted on having you naked on the floor again. At least those bed pads were getting usage, you thought. He did leave the mitts off and gave you your blanket, with you promising to be very careful not to get it dirty.

You knew what he meant. The thought made you blush.

So you had the floor to yourself, with Eijiro coming to sit with you. At least you could forget you were naked. A little bit, anyway. The two of you watched television, and Eijiro brought out his Switch. You were lost in the game for a time, exchanging one liners and teases with the red head.

A few times, you rubbed your eyes. You yawned, squirming. You weren’t certain exactly what the problem was. Not until Eijiro gave you a knowing look and saved the game, reaching over to take your control.

“Hey,” you frowned.

“It’s about that time, isn’t it?”

“What time?”

“Nap time,” he laughed. You scoffed and shook your head. “Aw, come on baby doll. You know you feel way better after some rest.” he coaxed. You shook your head.

“I can decide when I’m tired.” you declared.

“Well yeah, we all know that you can. But the point is that you don’t have to. I don’t know why you’re so resistant to it, love! Don’t you feel better when everything is calm and we take all the heavy thinking out of your life?”

You did like it. But telling him that was giving in. And you couldn’t do that. All you did was cross your arms and scowl at the floor. Eijiro got up in a hurry, rushing off somewhere. He came back with a diaper, the pink disposable kind you were used to, and something else.

“Lift up,” he said cheerfully. You lifted your bottom, letting him put the diaper under you. But he didn’t tape it up, didn’t give it a pat once he was done. He left you sitting in it open. He scooted in behind you, pulling you between his open thighs and adjusting things.
“There we go.”

“What are you doing?” you asked, curious.

“Hush,” he rubbed your side, pulling you to lean against him a little bit. He revealed that something else he had been holding, a bullet vibrator.
“This always gets you to calm down.”

“I didn’t say I wanted that!”

“That’s the point,” he said again, with the kind of patient voice one uses with someone who just doesn’t quite grasp a concept. This was the kind of voice that was usually followed up with the phrase; “Bless your heart.” or “Okaaaaay, sweetie?” It made you feel even smaller than you already did.
“We will decide for you. And I’ve decided this is the best way to put you down for a nap.”

“What if I didn’t want to.” you asked.

“You won’t, so it’s silly to worry about.” he soothed you. The bullet was clicked on and pressed to your clit. You moaned, long and low, the sensations making you jittery. You pressed against him, wanting to rest your head against his shoulder.
“No, no, you need to watch.”

“Eijiro,” you whimpered. He kissed your neck, gently using his wrist to make small circles on your clit. You gasped, feeling your cunt flutter. It made you want something buried deep inside of you.
“Daddy!”

“Yeah, baby? Am I Daddy too?” you could feel his grin. “That’s all any of us want. We just want to be your Daddies, and you just have to be the baby. Won’t that be better?” he went faster, clicking the intensity up. You cried out, your body trembling.

“Daddy, it feels good,” you whined.

“I know it does. And just think, as long as you’re good we can do this for you every day. Maybe a few times a day?” he nipped at your neck, suckled at your ear lobe. You moaned, your bare toes starting to curl.
“Once we get you all dumbed down, keep your mind blank with orgasms, your life will be perfect. You’ll be our perfect baby, our perfect little fuck doll. Won’t you? You’ll be so much happier.”

“Daddy,” you breathed.

“Oh, pretty, you’re so close. I can tell by the way your thighs are twitching. You gonna cum for Daddy? Make a big mess in your diaper. And then I can get you cleaned up and down for a nap.” his hand was going so fast. You shouted, cumming harder than you would have thought possible. You arched back, digging into him. You knew without looking you were squirting. Eijiro gave quiet praise throughout the whole thing.
“Almost done.”

“Done,” you mumbled, feeling light and dizzy. Eijiro nuzzled your neck and kissed your cheek.

“Pee for me, angel. And then you can nap.” you didn’t even think. It was a demand, and all you needed to do was what you were told. You released your bladder, listening to the hiss of it as it landed in the diaper.
“Fuck, I will never get tired of the fact that you piss yourself for me.” he waited for you to be done then carefully moved, laying you on the floor.

“Daddy,” you felt strange, not wanting to be left alone. Eijiro hushed you, walking over to the wipe warmer and grabbing another diaper.

“Cuddle blanket, baby. I’ll be right there. I’m just getting everything I need to make you comfortable.” you grabbed the blanket and buried your face in it. You didn’t look at Eijiro as he took away the soiled diaper and brought a fresh one.

You were a puddle as he changed you. No fussing, no whining, just letting him man handle you this way and that. When the diaper was on, he sat you up and pulled one of Izuku’s t shirts over you. You were rubbing your eyes and yawning.

“Now my baby is ready for a nap.” he said, satisfied. He picked you and your blanket up, carrying you to his room. He passed by the crib, putting you in the middle of his bed. He even gathered pillows to place around you, like he was afraid that you’d roll and tumble out.
“Wait,” you yawned. “Where’s puppy?”

“Oh, of course, can’t sleep without puppy.” he smiled, stroking your hair. He bounded off to another bedroom, came back with the stuffed animal. You took it and curled up on your side, instantly asleep.

Maybe, Eijiro thought, watching you, maybe all this time all you needed was a regular routine of orgasms, meals, sleep, and a blanket and toy. All things they could have done ages ago, he thought. They could have made your life better ages ago.

Chapter Text

“We can’t get someone to watch her.” Izuku said, running his hand through his hair. “And these are all day events.”

“I can watch myself.” you said from where you were seated in Hanta’s lap. He chuckled and gave you a cuddle and a kiss on the cheek.

“That sentence would carry a lot more weight if you weren’t in a diaper and footie pajamas on my lap.” he noted. You scowled, looking down.

“I like my jammies.” you mumbled. “They’re warm.”

“Of course they are.” Izuku soothed. “Hanta was just saying that he was afraid that it would be overwhelming for you. Weren’t you, Han?”

“Yes, that’s all I meant.” he promised. You got the feeling that wasn’t it, but he did apologize, and you were being snuggled, so it was hard to be mad. You rubbed your blanket on your face, listening to them talk.

“What if we all just tried to end our events early?” Eijiro asked. Denki sighed and shrugged.

“That still leaves her home alone for hours.” he pointed out.”

“I can do it! I can!” you piped up again.

“It looks like we won’t have a choice.” Katsuki shrugged. “She can figure it out.”

“Kacchan…” Izuku trailed off. Something passed between the two of them, you couldn’t quite tell what. You peered at them from over the edge of your blanket. Finally Izuku nodded, and the topic seemed to be dropped.

The day came that they were all busy. Work sessions, press conferences, meetings. There was nothing to do for it. Katsuki had filled several sippy cups and set them in the fridge, even though you insisted that you could manage yourself. He had even made a few sandwiches and placed them, too.

Before they left, everyone smothered you in hugs and kisses.

“You’re going to have to be a big girl.” Denki warned. “Don’t answer the door for strangers. Answer your phone if we text. Get yourself to the potty. Try not to make a mess.”

“Not a baby!” you insisted. You were clutching puppy in one arm and blanket in your other hand. Izuku chuckled, even when you threw him a dark look. And then they were gone, leaving you alone in the house.

Good! You could finally do what you wanted. They wouldn’t nag you, or insist you were a baby, or tell you it was nap time. You had the house to yourself, and you were free to do as you pleased.

You went to the couch and constructed yourself a nice little nest with the throw pillows and blanket. You rubbed blanket under your nose as you flipped through the channels. You landed on one of your favorite shows; a medical drama. You settled in, ready to follow along. You were in luck, there was an all day marathon! Your timing couldn’t have been better.

But even as the show started, it didn’t feel quite the same. You weren’t sucked into the story. You didn’t find yourself worrying along with the characters, or trying to guess the illness that the patient had. You squirmed a bit on the couch, wondering what happened.

Maybe they got new writers, you thought.

You picked up the remote and surfed for a bit longer. This time you landed on a cartoon channel. You perked up when you saw Bluey on the screen. Well, you thought, it couldn’t hurt to watch for a little while. And Bluey was acclaimed for being good for parents and kids.

You watched until it flipped over to another show, this one about a little girl who could talk to her stuffed animals. You cuddled puppy close, rubbing his ear between your fingers as you watched. But after awhile, you wanted a drink. You went to the kitchen, grabbing one of the sippy cups, silently grateful Kacchan had filled them for you.

The television was playing another show you weren’t too interested in, but you could leave it in the background as you colored! You dragged out one of your coloring books and the packet of colored pencils. You worked carefully, staying inside the lines, picking out the prettiest colors.

“Daddy!” you said once done, wanting to show the flower picture to someone. And then you remembered that there was no Daddy there, not a single one. You shifted and realized that you were wet. When had that happened? Thankfully no one was home. You lifted up your dress and changed yourself, although you found it was harder to get the tapes as secure as the others. It didn’t feel quite the same.

But no one else was home, so who cared? You shrugged and got a sandwich. It didn’t taste the same as when Kacchan would cut it up for you, though, you thought. It wasn’t as good. And there was no one to wipe your mouth for you, so you had to do that all on your own.

Lunch finished, you put your dishes in the sink and went back to the couch. You laid down, feeling your eyes grow heavy. You yawned and glanced at the clock. Naptime, you thought. But no one was home, no one could make you nap!

You could go to your play room, you thought. Eijiro had bought you some clay. You could make anything you wanted to. You thought about making some tacos for your dolls. You scrubbed at your eye with your fist. Yes, you thought, that would be fun.

You dragged puppy and blanket to your play room, opened the clay, and got to work. But it was hard to focus when you were so tired. Your tacos turned our weird. Why was it so hard to make lettuce out of clay? Frustrated, you balled it all up and threw it back in the container. Dejected, you went to the kitchen for another sippy cup.

Even the television seemed boring, you thought. You kicked out your foot, feeling grumpy, although you couldn’t say why. You squirmed, realizing that you were wet again. Frustrating bubbled inside of you as you stalked to the diapers, grabbing one.

But this time, it seemed so hard to try and put one on. You couldn’t seem to hold it up and manage the tapes. And tugging too hard on the tapes only ripped them. You shouted as you tossed the ruined diaper, plopping onto the floor.

“Hey babes! My event ended…early…” Izuku trailed off as he stepped in. He saw you on the floor, sobbing, your face in your blanket. He saw the ruined diaper and the wet one on the floor.
“What’s wrong?”

“I can’t do it!” you sobbed out.

“Can’t do what?”

“I can’t get it on and I thought if I showed you I didn’t need them at all you’d forget about it and I couldn’t make lettuce and the tacos were ruined and my sandwich didn’t taste the same.” it all bubbled out of you. Izuku hummed and walked over. He picked up the mess and tossed them away, then lifted you up.

“I’m surprised you’re awake. Isn’t this your rest time?”

“I don’t need a nap!” you howled. Izuku’s eyebrows went up. He carried you to the room he and Katsuki slept in and laid you on the bed. You continued to cry while he diapered you. He picked you up and sat on the bed, his back to the headboard.

“You need to calm down.” he said softly.

“I can’t! I can’t!”

Overtired, Izuku thought. You were overtired. He reached into his bedside table and pulled something out. In a moment it was popped into your mouth. Another penis pacifier. You made a growling sound and went to spit it out.

“I will get the straps.” Izuku warned. You gave him a sad look and cuddled into him. He grabbed your blanket and puppy, handing you the toy and wrapping the blanket around you. You sniffled, burying your face in his neck. He felt the shield of the pacifier, felt your body starting to go loose.
“There you go, good job.” he praised.

“Not tired.” you muttered around the pacifier. You gave a few sucks, your eyes closing. Izuku didn’t speak, continuing to hold you until you had dozed off. He waited even then until you were fully asleep. He carried you to the crib, laying you down and pulling the blanket up over you. Puppy remained in your arms.

“How bad was it?” Katsuki’s voice came from the doorway.

“Not as bad as it could have been.” Izuku shrugged. He brushed your hair back and stepped away from the crib.
“But… she is a baby. Even though she’s fighting it.”

“Good. It’s working.” Katsuki grinned, wrapping his arms around Izuku’s waist.

Chapter Text

You spent the next few days docile, obedient. Your head was spinning, replaying things. How had you just melted down like that? Izuku kept saying you were overtired, that was all it was. Of course he believed that you could have changed your own diaper. Yes, he knew that you would have been perfectly fine if they hadn’t come home until late.

No one was blaming you or accusing you of anything. What were you so worked up about? Come and relax, babes, come and calm down. Wanna color? Oh, let’s watch that show you like so much. Every single time you tried to bring it up, pick it apart, Izuku always had the perfect distraction.

And if he couldn’t distract you with your puppy, or blanket fresh from the washer, or television, he’d ease you into his lap and start doing that knee thing, rubbing against your clit. It always worked to blank out your mind.

Well, you decided. You’d simply had enough of all that. You’d show them that you were over it. You only acted like that because they wanted you to act like that, you decided. You were going to show them you were ready to move on.

It was easiest when Denki and Eijiro were there with you. They got you into a clean outfit, a dress this time. And it might have been a dress any regular woman would wear, you thought. It was cut in an almost little girl fashion, with the full skirt and the fluttery sleeves. But you could just call it a sundress.

“I am so behind in paperwork.” Denki groaned.

“Me too,” Eijiro admitted. He rubbed the back of his head and glanced at you thoughtfully. “Babes, will you be okay in your playroom and with the television?”

“Of course,” you shrugged.

“We did just get her in dry pants.” Denki pointed out. “She’ll be fine for awhile.” he flipped the television on and ruffled your hair. You leaned into the affection, and he bent down to kiss you on top of the head.

You smiled as they headed for the office. Eijiro glanced at you over his shoulder. He was clearly bothered by something, although he didn’t seem to be able to verbalize it. You clutched blanket in one hand, blinking innocently.

“Call for Daddy if you need something,” he said finally. You nodded and he left. And now, you thought, you just had to wait. You climbed onto the couch, not really watching the television. When enough time had passed, you went to the coat closet. You eased it open, reaching for your purse, sitting there alone.

Your wallet was still there. With your work ID, a few crumpled tissues, half a pack of gum. Some assorted coins littered the bottom You slowly pulled your purse out, keeping an eye to see if anyone was coming.

Why should you feel guilty? It was your purse! These were your items! In your wallet, in the secret zip compartment remained the house key. And you had some cash in there. It was all yours. And no one told you that you had to stay in the house. You put your purse over your shoulder and stepped out. Carefully, slowly, you locked the door behind you.

And just like it was any other day, on any other street, in anyone else’s life, you began to walk.

***

The first stop was a bathroom. You ripped off the stupid diaper and threw it in the trash. When you got home and they saw nothing had happened, they’d agree to putting you back in your underwear anyway.

You headed down the street, to the busy part of the neighborhood. There was a bookstore, a cafe, a little grocery store. You looked around, contemplating your options. Bookstore first, you decided. You walked in confidently, holding the strap of your purse.

The man at the counter glanced up from his book to smile at you, then went back to reading. You nodded back and went to look at the paperbacks. You were scanning the titles when a brightly colored corner caught your eye. You turned your head slowly to the children’s section.

Little chairs, bean bags, books that featured Bluey and some of the other characters from the shows you liked. No no, you told yourself with a shake of the head. You don’t need any of that. Quit thinking about it. It’s only because they were messing with your head. You pursed your lips and grabbed a few books, ready to head to the check out.

You walked by the display of coloring books. There was one, a Bluey one, you didn’t have. You had grown up ones at home. You shifted your weight foot to foot. Would anyone question it? Would anyone care?

You snatched the coloring book and went to the counter. You were all ready with a lie about your nephew needing the coloring book, but the cashier didn’t seem to notice or care. He gave you the total, swiped your card, and sent you on your way.

You clutched your little paper bag and looked around. People were walking by, not noticing. No one knew you’d slipped out, no one knew you were meant to be wearing a diaper, and no one knew that you had totally bought a child’s coloring book.

You could have skipped to the cafe. As it was, you were bouncing on your toes when you ordered a hot chocolate with extra whipped cream, and a cookie to go with it. Giggling, you headed to a table, pulling out one of your books.

The hot cocoa was delicious, you thought. The perfect temperature. You hummed as you turned the pages, lost in another fairy tale romance. You bit into the cookie, grinning to yourself.

“I do love to see a woman who knows what she likes.” someone said near you. You gasped, jumping, spilling the hot cocoa in your lap.

“Oh,” you frowned. It wasn’t super hot, but it wasn’t comfortable. There was cocoa on the ground, too.

“I am so sorry,” the man stepped closer. You shrank away a bit. You didn’t know him at all. He had a napkin in one hand, was reaching for your face.
“You’ve got some whipped cream right–.”

“Don’t,” you tried to shake him off.

“Just let me get it, it’s fine. I’ll buy you another hot cocoa.” he reached for your face again.

“Get away from her.” a voice snapped. You looked up and saw Katsuki. He was speaking to the man, but his eyes were on you, his arms crossed.

“This your girl?” the man snorted.

“Something like that. I don’t have to explain to you, extra.” he grabbed your elbow and hoisted you up. “Come on.” he barked.

You were frog marched to the car. Katsuki opened the back door and almost shoved you in. You swallowed hard. The car ride home was silent. You squirmed, feeling your bladder nagging at you. Now was not the time, you told yourself. Just hold on!

Katsuki parked the car, outrage oozing from every pore. You bit your lip as he ripped you from the car and hauled you inside. You clutched your bag of books. All of them were in the living room, staring at you.

“Start talking.” Katsuki spat.

“Okay, um, well, so…” you coughed, clearing your throat. “I wanted to go out.” you straightened your back. “And I’m an adult, and I don’t need to ask any of you before I leave this house! You want a baby, but I’m not a baby.”

“It is not very grown up to sneak out of the house without telling anyone.” Izuku said calmly. “We always tell each other where we’re going. And no one doubts that we’re adults.”

“I know, Daddy,” you took in a deep breath. “I thought that you’d see.”

“All I see,” Katsuki said darkly. “Is a spoiled brat who doesn’t know how good she has it.” he sat on the couch and hauled you over his knee. Your damp dress was pulled up and he observed your bare ass.
“You really like pushing the envelope, don’t you?”

“I don’t need it!”

“Shut up,” Katsuki snapped. He had both your wrists in one hand against your back. His leg was over yours, pinning you down. Without another word, he began to slap your ass viciously. The sting and burn set in and you wailed, your back bowing.

No one was speaking. You sobbed, unintelligible. You couldn’t even tell how many he had given you. But you did feel when hot wetness drizzled from you, seeping into his jeans. You knew Katsuki knew, but he didn’t say anything.

Just as suddenly as he had started, he finished, walking you to the corner. He didn’t even look you in the eye as he stuffed you there. You fidgeted for a minute, going to turn around. But before you could, you heard the snapping of fingers.

You were meant to be still. You weren’t meant to move.

Time was taking forever. You were still in the wet dress, you smelled like pee, and no one was talking to you. You continued to stare at the wall. Maybe when you turned around, they’d decide everything was over.

“Come here,” Izuku called. But he didn’t tack on a term of endearment, and he wasn’t talking to you in that sing-song cutesy voice. Dread rose in your stomach. You turned and dragged yourself towards him.
“Look at me.”

“Daddy?” you looked up at him. But he was giving you the harshest look you had ever known from him.

“We were worried sick.” he said. “Denki and Eijiro had no idea where you’d gone. You had just disappeared. Anything could have happened to you!” he was nearly shouting. You whimpered, swiping at your eyes.
“To walk out like that?” he shook his head.

“You’re going to have consequences for this.” Hanta spoke up. You swallowed hard and looked down.

“Bath first.” Denki stood up. “Everyone needs some time to cool down.” he put an arm around your shoulder. You were silent walking to the bathroom. He helped take off your dress. You watched as he started the bath. He put in epsom salts, but no bubbles, no bath crayons, and no tub toys.

“Are you mad?” you asked.

“I’m not happy.” Denki said honestly. “Honey, you know you can’t run off.” he said sincerely. “I was worried sick. I was terrified.”

“I just…” you trailed off. “No one listens to me.”

“We do listen to you.” he corrected you. “We know what’s best for you. Just because you don’t get whatever you want whenever you want doesn’t mean we don’t hear you.”

You didn’t have the language to tell them that they didn’t understand. They were taking something away from you, but you couldn’t quite say what. Denki helped you into the tub. You sniffled a bit as he took a wash cloth and began to wash you.

“Early bedtime for you.” he sighed. “Tomorrow is going to be interesting.”

Chapter Text

You slept in Denki and Hanta’s room, although it was in your crib. Part of you thought that if they had been worried sick about you like they claimed, they would have wanted you in bed with them. When you were awoken, it was by Izuku. He peeled away your blanket and eased puppy out of your arms.

“Daddy?” you mumbled.

“Mmhmm,” he agreed. “Let’s get breakfast.” he kissed your temple and carried you to the kitchen. You looked around, waiting for the shoe to drop. But they were calmly eating, talking about their days. You were given a plate of scrambled eggs and bacon, and a kiss on the head from Eijiro.

Maybe they calmed down, you thought. Maybe they weren’t mad after they’d slept on it. You quietly ate your breakfast with the little plastic fork they gave you. You let your face and hands be wiped clean by Denki, giving him a smile. He smiled back, pressing kisses to your cheeks until you giggled.

“Looks like we’re ready then.” Katsuki announced. Everyone else nodded in agreement. You wondered what they were ready for, but had learned to keep quiet. Katsuki got you out of the highchair and carried you to his room.

“What are we doing?” you asked. He hushed you and shook his head. You were stripped quickly, laid down right in the middle of the bed. Strange. You opened your mouth to ask again, but he silenced you with a snap of his fingers. He knelt next to you on the bed, putting your hands in those mitts you hated.
“No,” you whined.

“Shut up.” Katsuki ignored you otherwise. One arm was pulled, a cuff around your wrist. The other one got similar treatment. You frowned, testing the bonds that kept your arms spread out. The blond continued to ignore you. He moved to your ankles, cuffing them too. You were spread eagle on his bed.
“Almost done, babes.”

But this wasn’t said to assure you, like normal. This was some kind of warning. He made short work of your diaper, putting you in a thicker one. You had no hope of closing your thighs. You whimpered, which was ignored.

A belt was placed around your waist. You craned your neck, realizing it was a harness. While your head was lifted, Katsuki was placing something in your mouth. Another penis pacifier, you thought, the weight and shape familiar on your tongue. He strapped it behind your head, which did not do much to make you feel better.

Finally, Katsuki slithered off the bed and plugged something in. He came back with one of the wand style vibrators. You tried to protest behind the gag. But nothing intelligible came out. And the cuffs were strong.

The head of the vibrator was placed over your clit. At least you had the diaper giving you some kind of padding, you thought. The harness was adjusted, and Katsuki clicked it on. You whimpered, your head digging back into the bed.

“All right, you’re all set. We’ll check on you in a little while.”

And you were alone in the room.

***

The first orgasm hit you hard and fast. You screamed behind the gag. But you could barely catch your breath before you felt the buzzing of the vibrator arousing you again. This was going to overstimulate you, you thought.

And it did. You managed two orgasms. Then you were sobbing, howling. Your body burned, from the top of your head down to your toes. You struggled against the bonds. You hoped if you moved enough, you could adjust the vibrator, and it would maybe be on a different part of you.

But Katsuki was very good at positioning. You couldn’t escape it. Tears flowed down your face, soaking your hair by your ears. You struggled, strained, tried everything you could. It must have been hours, you thought, before the door opened.

You were barely able to open your swollen eyes. Hanta stood there, looking at you. You stared back, silenced by the gag. Hanta came and switched off the wand, though he did not take the harness off.

“Little break.” he murmured, brushing your hair from your sticky face. “Let Daddy get something to clean your face, and I’ll check your diaper, and then get you a drink.”

You were still as he ducked into the bathroom and came back with a warm wet cloth. You hummed as he wiped your face, gave you kisses to your temples. You relaxed, the tension wilting from your body.

Hanta did take off the harness to change your diaper. When had you pissed, you wondered. You couldn’t bring yourself to be embarrassed as he wiped you clean, gave you a little cream, and then put on a fresh diaper.

The gag was undone, and a straw placed in your mouth. You drank gratefully. But before you could speak, Hanta was pushing it back in. You let out a whine of protest, but Hanta could only shrug.

“Consequences for actions, my love.”

The harness was replaced, the fit checked, and the wand switched on again. You howled behind the gag, back bowing. Hanta watched for a moment. He laid out on the bed next to you, the tips of his fingers dragging up and down your body.

Every inch of you was hypersensitive. Was he trying to help, make it worse, or distract you? Your skin immediately broke into goosebumps. You thrashed in the cuffs, hoping that would make Hanta see how pitiful you were. But he laughed. Laughed! He nuzzled into your neck, his hand wandering down to your tits, pinching your nipples.

It was like he knew that was the way to tip you over. You screamed hotly, back arching sharply as you came. Hanta laughed again, an arm around your waist, coaxing you back into laying down. You were crying again, and he leaned up to kiss your gag.

“You’re fine.” he assured. “Someone will come and get you later.”

You were left alone again in the room.

You came again and again, and eventually, you noticed the edges of your vision going black. You couldn’t warn anyone, couldn’t ask for help. All you could do was let it take you under, dark and black and blissfully free.

When you woke again, someone was undoing the cuffs. They were shushing you, rubbing your belly. Moving you around carefully, the harness was taken off you. You whined still, a hand stroking your cheek. You cracked your eyes open and saw Eijiro. He smiled brightly when he saw your eyes open.

“Hey beautiful.” he purred. “Bet you’re worn right through, huh?” he sat you up, letting you take a minute to get your bearings.
“I got you in a dry diaper.” he grabbed a blanket, your blanket, you noted happily. He wrapped it around you and picked you up. Just as well, your legs were boneless. And you were aching to be held. You let your arms wrap around his neck, your head on his shoulder.

Eijiro tipped your chin and kissed your lips, the sweetest little kiss he could manage. You smiled softly, laying against his chest as he carried you to the living room.

“Well, well, well.” Katsuki smirked. “Looks like someone got the brat worked out of her.”

“Oh, Kats.” Eijiro sighed. “Do you have to rub it in?”

“Yeah,” he shrugged. “Because she was a bad girl and she knew it when she did it. The only way we can keep her calm is to keep her fucked out. Cock drunk. Of course,” he rose to come and take you from Eijiro.
“She was so naughty this time she didn’t deserve our dicks. Just that toy playing against her naughty little cunt in a diaper, huh?”

You blushed, but were too wrung out to fight. You huffed a little and pressed your face into Katsuki. He laughed, a cruel sound, but softened it with a kiss to your lips.

“Daddy,” you mumbled.

“Yeah, you’re here with Daddy now. And you’re gonna be a good girl.” was it a threat? A foreshadowing? A promise? It didn’t matter.

“But–.” Denki whined. Hanta glared at him and shook his head.

“You were foolish.” he snapped. “You could have been killed. And then what, Denks? Then what?” Denki didn’t say anything. Neither did you, sitting in the middle of their bed, confused. You knew they had been out the other night, knew that it hadn’t gone exactly to plan. But the details were never shared with you, and you were hardly in a position to ask.

Hanta turned his attention to you. You were fresh from the bath, your hair out of your face. You smelled like green apple bubble bath. Hanta smiled and you couldn’t help yourself from smiling too, reaching your arms out to him.

It wasn’t so long ago you wouldn’t have been able to dream about doing this. Now demanding affection seemed like a second nature. They were nearly always happy to give it to you. You were so rarely denied.

“Baby girl,”Hanta said happily as you climbed into his lap. They hadn’t bothered to put you in pajamas or a diaper, leaving you naked for them. You nuzzled into his neck, feeling him tilt your head so he could kiss your cheek, your jaw, your neck.
“Such a beautiful girl.”

“Daddy,” you hummed. “I’m so happy to be here with you.” he laid himself down, leaving you straddling his pelvis. He rubbed you and down your bare sides, making you shiver. Hanta laughed. Denki remained in the chair in the corner, squirming.

“She is so ready, Denks.” Hanta sighed. “I’m gonna fuck her. And you’re gonna sit there, and you’re not gonna touch yourself.”

“That’s not fair!” Denki whined. Hanta snorted.

“You fuss so much, I wonder who the baby here is.” you blushed. But Hanta lifted you up and shimmied out of his pajama bottoms.
“C’mon baby.” it was so easy for him to spin you around, reverse cowgirl. “Back that ass up.” he gave it a little crack, laughing when you squeaked.

“Han…” Denki trailed off. You could see by the way he was squirming that he was hard in his pants. Hanta snapped his fingers and glared at him.

“Think about it next time you wanna be a jackass. Think about what you’re missing out on.” He pushed you forward until your hands were on his thighs, your bottom in the air. One finger traced delicately down your pussy.
“Already getting wet for me? You’re just the naughtiest little girl.” he laughed. Your face was hot and you buried it in his legs.

Hanta didn’t seem to care, two of his long fingers working in and out of you, rough and fast. Sometimes it was like this, you thought. Sometimes they treated you like a porcelain doll. And sometimes they treated you like a fuck doll.

You couldn’t decide what you liked more.

“Daddy!” you whimpered when he crooked his fingers. He laughed, his other hand moving to find your clit, rubbing it harshly. You moaned, your head jerking up. Without thinking, your hips were rocking, getting more friction, more pressure.

“So ready and willing.” Hanta said appreciatively. “Don’t worry, Daddy’s gonna take such good care of his baby. Daddy always takes care of his baby.”

You were on the verge of your orgasm when he withdrew. You looked over your shoulder, throwing him a dark look. He laughed, manhandling your hips until you were sinking onto his dick. That aching need inside of you was finally fed, you thought. You sat up straight, the way they liked you to.

“Ride me,” Hanta demanded. And who were you to deny Daddy? You inhaled and began to ride. You rolled your hips, then set a pace rising and falling. Denki let out a strangled sound in the corner, and you couldn’t help but feel a little bit bad for him.

You forgot when Hanta was rising up to meet your pelvis, and his finger was against your mouth. You sucked on them, getting them thoroughly wet. There was a small word of praise before that wet hand trailed down to find your clit again.

“Hanta, I wanna…” Denki’s eyes were big and bright there in the corner.

“Too bad.” Hanta sounded a little breathless. “You’re gonna watch me make our baby explode. And then I’m gonna fill her up with cum. She’s gonna be a filthy–fucking–mess!” he punctuated each word by thrusting hard into you. His fingers played with your clit, rolling it ever so slightly the way you liked, giving it those little taps that made you gasp and choke.

“Goddamn,” Denki sighed. You looked up, locking eyes with him, just as you came. Hanta cried out, feeling your pussy spasming around him. His hand left your clit, holding you by the sides. It was easy for him to push you to your stomach. He pressed into you from behind, with you barely being able to hold your head up. Hanta was looking at Denki, whose mouth was open, his chest heaving.

You wondered if he could cum in his pants just from watching.

Hanta bit down on your shoulder as he came. You whimpered, head falling to the bed, nearly overwhelmed. Hanta rolled the two of you to your sides, breathing hard. He pulled out, hushing you when you made a sound.

“Such a good girl. You’re wonderful.” he sighed, forehead sweating. “Denks?”

“Yeah, I got it.” he grunted, getting off the chair. He walked like it hurt, and maybe it did, being so hard. Hanta got up and padded for the bathroom. You were blushing as Denki slipped a diaper under you, open.
“Go pee.”

“Huh?” you blinked stupidly. Denki rolled his eyes and gave a huff.

“Hey!” Hanta stepped back in. “You’re not taking it out on her. Baby didn’t do anything wrong?” he glared. Denki looked ashamed.

“He’s right, I’m sorry, love.” he stroked your cheek. You nuzzled into his hand, and he smiled.
“Go pee for me. You need to pee after sex. If you get a UTI…” he trailed off. You wondered if he was afraid of how you’d act with one, or how others in the house might react.

You bit down on your lower lip, closing your eyes. You felt yourself pee, hot and too close to your skin. You squirmed until he put his hands on your thighs.

“Theeere it is, good job. You’re so good, aren’t you?” he had the wipes, cleaning you up and sliding down a fresh diaper along with a little sprinkle of powder. You were taped in, drowsy in your afterglow when Hanta laid down next to you. Denki was there a few minutes later, sliding in on the other side of you.

You could have purred. Their arms were over you, and you were safe, warm, and adored in their bed.

Chapter Text

“What’s wrong, doll?” Izuku asked with a frown. You shrugged, unable to explain. You had felt off all day. Izuku gave you a thoughtful look. He lifted you up to give you a cuddle, feeling your belly at the same time.
“Oh, I get it.”

“What do you get, nerd?” Katsuki muttered as he came into the living room. He snagged you from his husband and sat with you on the couch. You nestled against his chest.

“When was the last time the baby pooped?” Izuku asked casually. You whined, burying your face in Katsuki’s pecs. He shrugged.

“I don’t keep track. It’s never been a thing.” and he was right. That part of your life had never been discussed with them. You sometimes asked to use the bathroom, they’d help you off with your diaper if you needed, help you wash your hands when things were over.

“She’s been uncomfortable all day.” Izuku pointed out. “She’s fussy and she hasn’t wanted to eat.” you hadn’t felt much like eating breakfast, hadn’t wanted a snack. Katsuki rubbed your back. You snuffled, face hot. There was no way you wanted to have this conversation.

“So we’ll give her some prunes to eat, or some senna tea.”

“We could…” Izuku agreed. “But I think we might need to jump start her.”

“You could be right.” Katsuki sounded doubtful. You were shaking your head frantically. He hushed you and sighed. You were hoping that you convince Katsuki not to want to do that.
“What did you have in mind, ‘Zuku?”

“Suppository is faster than a laxative.”

“Enema is even faster.” you squeaked at that, trying to get off his lap. His arms were secure around you, and he didn’t seem to notice you trying to escape.

“I don’t think she needs that yet. I’d rather try a suppository first.” Izuku rubbed the back of his head.

“No! I don’t want that!” you snapped.

“Honey, you should have said something to us sooner. We could have given you some warm apple juice or some fiber supplements or something.” Izuku shook his head at you. “We could have fixed it before it got this far.”

“It’s embarrassing!” you insisted.

“You already piss in a diaper and let us run your life, why is this different?” Katsuki raised an eyebrow. You pouted, refusing to meet him in the eye. All you could do was shrug. You didn’t have an answer.

Izuku pressed his lips together. He went for his jacket, keys jingling in his hand. You had the feeling that he wasn’t leaving to bring you back ice cream. You tried again to squirm away from Katsuki.

“Daddy is bringing back some medicine to make it all better.” he said.

“I don’t want it.” you felt desperate.

“You don’t make the decisions here, do you?” Katsuki cupped your face in his hands. You had no argument for that. He turned on the television, grabbing blanket for you to snuggle, hoping to calm you down.

But once Izuku left, it only left you with time to think about it. Your face was burning, and you whimpered, seeking solace in Katsuki’s neck. By the time Izuku returned with a paper sack, you were in tears, refusing to be comforted.

“See? This is what I meant by fussy.” Izuku sighed. He bustled to the kitchen and then back to the living room. You wondered what any of this was going to have to do with the kitchen, and when he came back, he still had the sack. He spread an old blanket on the floor and beckoned to you.

“Do what Daddy says,” Katsuki warned, setting you on the floor. Slowly, you walked towards Izuku, refusing to look him in the face. He had no problems hauling you towards him by your wrist. He was sitting criss cross on the blanket and unsnapped your onesie with you still standing.

“Don’t need this right now.” he smiled. You did not smile back. He laid you down on your back, the same gentle way he always did. You diaper was undone and rolled up to be thrown away, even though it was dry.

“Daddy,” you began.

“I know, you’re all worked up.” he shook his head. “You’ve been thinking about it since I mentioned it. Kacchan?” something was tossed to him, caught easily out of the air. “This will help, babes.” another pacifier was offered to you. You knew by now that refusing it would only end in it being strapped to your mouth.

He rummaged in the paper bag, but you stared up at the ceiling. You could pretend that you weren’t there, maybe. Like that had never worked for you before. But desperate times called for desperate measures, you thought.

Izuku opened a small cardboard box, a tiny bottle of KY jelly, and then a packet of nitrile gloves. He snapped those on, then scooted between your legs. He kept one gloved hand on your belly.

“I’m going to tell you everything I’m going to do, honey. Are you listening?” he gave a little rub. You nodded jerkily.
“Good girl. I’m going to put a little bit of lube on this suppository and slide it into your sore little bottom. I bought extra thick diapers, since I didn’t know if your regular ones would work, and we don’t want a worse mess, do we?”

“No, Daddy.” you mumbled past the pacifier. You found yourself sucking on it anxiously, glad for the distraction.

“And then I’ll rub your tummy, and we’ll give the medicine a chance to work. Okay, baby?” you couldn’t bring yourself to protest, so you said nothing. Izuku nodded and applied the lube to the little bullet shaped suppository.

You clutched handfuls of the blanket as you felt him pressing it in. It wasn’t overly large. Smaller than Eijiro’s fingers, at least. But still, you thought desperately. You didn’t like it! You didn’t want it.

Your legs were lifted against Izuku’s shoulder for a few minutes. You could feel the weight of his gaze on you. After about three minutes, he grabbed a diaper from the package and settled it under your bottom.

How was it even thicker than your normal ones? You could hardly believe that such a thing existed. You fidgeted as Izuku put your legs down. His hands reached for your belly, his touch so gentle and full of love even with the gloves.

First, he used his palm to rub circles in your belly. You relaxed at the motion, enjoying how soothing it was. After a little bit of that, he put his hands just under your hips and started rotating them. You closed your eyes, sucking the pacifier.

“That’s better, isn’t it? Just relax, let the medicine work.” he sounded pleased. You turned your head to the side, not reacting as he began to bicycle your legs. Your stomach let out a rumbling sound and you whimpered.

“Don’t fight it.” Katsuki warned. “Keep breathing. You’re fine, baby.”

Izuku lowered your legs and helped you stand up. You felt pressure growing, pressing your thighs together.

“Go see Daddy,” he encouraged. You walked slowly, carefully. Your stomach ached. The cramps were coming. Katsuki held his hands out to you. Your whole body felt like it was growing hot.

“Take me to the toilet.” you said urgently, desperately.

“No,” he said gently. You spit out the pacifier.

“Please, I–I’ll say something next time. Daddy, Daddy please! Please take me potty!”

“Don’t get upset.” he warned. He put the pacifier back in your mouth, taping the shield of it. You felt tears dripping down your cheeks as your body lost the fight with the cramps. You were shitting in your diaper, you realized, while the two of them watched. You moaned, feeling the poop sliding out of you.

“Here,” Izuku murmured. He came to kneel behind you, put his hands on your shoulders and encourage you into a squat. Katsuki held your hands, rubbing the back of them with his thumbs. “This is a much better position. Don’t worry, I’m holding it for you, you just focus on relaxing lovey.”

You pressed your forehead to Katsuki’s knee, trying to clamp down. But once your body realized that there was relief, sweet sweet relief, it wasn’t going to stop. You kept shitting, filling the absorbent padding on your bottom. Katsuki let go of one of your hands, stroking your hair.

“Such a dumb baby.” he clicked his tongue. “Gotta have us to help you do this, too?”

“Oh Kacchan, don’t.” Izuku gave him a look. “She’s being so good going along with this, isn’t she? Yeah, and it’s hard for her. But she’s being such a good girl. Almost done, sweetie?” he asked you.

You ignore him for a few moments. You felt your bladder give, too. Your diaper was getting saggy, squishy between your thighs. After another moment or two, you lifted your head, wiping at your eyes.

“Now my baby feels better.” Izuku sounded satisfied. “Daddy will go and start you a bath, you need it after that. But I’ll get you cleaned up.” he walked you back to the blanket and laid you down, wipes from the warmer in his hand.
“Oh, don’t cry honey, don’t cry.” he untapped it wiping the filth from your bottom. You kept swiping at your eyes, unable to bring yourself to stop.

“Come on, babes.” Katsuki was back in the room, picking you up. How could anyone want to touch you right now, you marveled? You were filthy! But Katsuki kissed your cheek and brought you to the bubble bath.
“There,” he hummed. “You sit here and have a soak, relax. You’re going to be okay. I think we’ll work on adding some fiber to your diet.” he stroked your hair, then ran a wash cloth under the cold tap, folding it and putting it on your forehead.

You soaked in the tub, closing your eyes. Your stomach still felt a little sore, but you did feel better. Just as the water is cooling, Izuku was back, helping you out. He dried
your whole body carefully, bit by bit.

“Much better,” Izuku nodded, looking well pleased. You blinked slowly, feeling unable to speak. He uncapped a tube of rash cream, parting your asscheeks a little so that he can smear it on your little hole.
“There you go, much better.” a thick diaper was strapped on you again, a t shirt pulled down over your head.

“Daddy,” you sighed. He put his arms under your bottom, lifting you up. You felt exhausted, weak and limp. Wrung out like a rag, you thought. He carried you towards the bedroom he shared with Katsuki.

“Let’s lay down here and watch television.” he suggested. He arranged you so your head was on his chest, with you facing the television. Katsuki was in quickly, holding another sippy cup full of colored fluid.

“Some sports drink, it’ll make you feel better.” he offered it, and you had a chance to look at the sippy. It was a pastel translucent one, with a silicone spout. It looked, you thought, like a baby cup. You were too tired to fight, too exhausted to worry about it. You began to drink. Your feet dangled towards the side of the bed. Izuku’s hand carded through your hair. You relaxed, taking lazy sips now and then.

Katsuki looked satisfied, leaving you to snuggle Izuku.

Chapter Text

“Oh yeah? That feels good?” Eijiro teased from his seat on the couch. You whined, turning your face, red cheeked and wet with tears towards him. He laughed softly.
“Aww, babes, what’s wrong? Not enough?”

“Daddy,” you whined. You wanted to crawl into his lap. You wanted him to take the diaper off and fuck you. But no, you sulked. No, instead he had found the stupid egg shaped vibrators, with the cords dangling.

Eirjiro had coaxed you to the quilt spread out on the floor. He had laid next to you, giving you kiss after kiss until you felt breathless and dizzy. He worked off the dress you were wearing, until you were bare and blushing on the quilt.

He reached for the tapes of your diaper, and you thought for a glorious moment he was going to take it off. You laid, still and docile, ready for him. But he showed you the toys, grinning as he did. You barely had time to think before he was lubing up one of them.

“That a deep breath for me, love.” he murmured.

“I don’t–.” you began.

“Did I ask for commentary, or did I tell you to do something?” when he scolded, he was so gentle about it. It almost hurt more than when Katsuki went after you. You inhaled, exhaling slowly, feeling the little vibrator wedging into your ass. You whined, wanting to squirm.
“Look how good my baby is, doing what she’s told.” he praised.

And that praise shouldn’t have made your cheeks go pink. It shouldn’t have made your heart flutter in your chest, shouldn’t have made you want more. While you were thinking about this, the other egg went into your cut, already beginning to get wet.

“Daddy!”

“Are you good and full?” he asked, rubbing your pelvis. “Feel nice?” it didn’t really feel nice, you thought. But it didn’t feel bad, either, so what could you say? He taped your diaper back up and went to sit on the couch.

That was it? He was going to sit there and leave you feeling like that? You sat up slowly. He could have at least given you some clothes! You were giving him a dark look when you felt it. Both of them began buzzing inside of you. You gasped, your body going stiff, clutching handfuls of the quilt.

And so that had lead to this. Eijiro was somehow able to watch television casually while he kept the toy going. You saw the little pink remote in his hand. And he wouldn’t keep it steady, either, you noted. Just when you were getting excited, the toy would turn off, jolting you away from an orgasm and leaving you feeling icy.

You would calm yourself down, try and distract yourself with the television, or a toy or something. But just when your heart was at a steady beat again, and you were feeling settled, he’d press another button.

After three or four rounds of that, you were a whining, crying mess on the quilt. Eijiro had moved on from turning it on and off, no longer satisfied with that. Instead, he was varying the speed and intensity of the vibrations. You had rolled onto your belly, your ass high up in the air. You were humping nothing, trying to get more and more of the sensations, eager for something. Your hips rolled as you desperately sought out friction.

“Such a silly baby. Drooling and whining on the floor. Having a tantrum because that naughty little clit isn’t getting attention.” he clicked his tongue in mock disapproval. You shook your head, closing your eyes again. The eggs were going faster. You thrust back, sensing that you were finally close to release.

Didn’t matter if he teased you or taunted you, you thought. You were finally going to have your release. And it was going to feel amazing, you thought smugly. You were going faster and harder, finally getting everything ino just the right position.

“So close!” Eijiro laughed as he switched things out. You gasp and collapsed down, giving him a dark look. He laughed again, twirling the remote in his fingers as he watched you. You pulled yourself up on your knees.

“Stop it!” you demanded. Although you couldn’t look very intimidating, in a big pink diaper with vibrators shoved up you and nothing else. Eijiro gave you a look full of pity and hit the power again. Only this time he didn’t do a slow ramping up.

Everything hit you full force. Your hands went to your thighs. Your whole body spasmed as you felt the vibrators rubbing against every perfectly sensitive part of you. Eijiro was silent as he watched. Your nipples were hard, your breasts bouncing a little as you moved with your orgasm.

“Daddy, Eijro,” you panted. He tilted his head and watched as you came, spine bowing, lifting yourself off where you were sitting on your knees.

When it was over, you flopped to the quilt. Eijiro made his way over. He slowly, carefully, rolled you onto your back. He said nothing as he rubbed your belly again, watching you for something. You wondered what he was seeking out when he opened the diaper and pulled out the toy.

“Oh!” you whimpered, hypersensitive and overstimulated. He hushed you before picking you up, letting you rag doll against his chest. Your arms were slung over his shoulders. You were confused when he sat down on the couch, juggling you from arm to arm as he shimmied out of his pants.

“You be still.” he murmured in your ear, letting his mouth trail from your ear lobe down your neck. “And let Daddy deal with everything.”

You didn’t need to be told twice. You were limp while Eijiro lowered you onto his hard dick. You left your arms around his neck while he gripped your hips and bounced you. You were going hard and fast, and it was too much, too soon after an orgasm. You couldn’t seem to form the word to tell him.

He wouldn’t have listened anyway. Eijiro bit down gently on your shoulder, pulling off to lick and suck at the injured flesh. Your body jolted with his ministrations. You wanted to protest, wanted to dig your nails into him. You wanted to scream. You wanted to beg for more. Instead, you were left at his mercy.

And he knew how to work you. They all did. He was close, you could tell by the face he was making. It was enough to tip you over, feeling him cumming inside of you. You came, screaming as the burning fire spread throughout your body. Your eyes rolled back, and you saw black for a few moments.

“Aww, baby.” Eijiro nuzzled your neck. “Sometimes I forget we have a diaper on you for a reason.”

“Huh?” you blinked, eyes blurry. “I didn’t–.”

“No no, you didn’t have an accident on me. You just squirted. I love knowing I can make you squirt.” you realized his shirt was wet and shook your head, willing it away. You could barely string together a sentence right now.

Eijiro said nothing as he carried you to the quilt. You looked with hazy eyes as he put you back in a diaper and grabbed himself a clean shirt from the laundry basket. You waited for him to put clothes on you. Instead, he lifted you back up and let you rest in one arm as he went to the fridge. You left your eyes closed, not worrying about what he was doing.

Eijiro took you back to the couch, settling you to lay with your head in his lap. You smiled when you felt your blanket being draped over you, one hand going to wrap around it. His hand settled on your head, rubbing your scalp. You hummed, feeling so relaxed and empty headed. He stroked your hair, putting on one of the shows he liked. It was a nice hum of background noise.

“Oh, here, hon.” he handed you something. Your arm flopped around until you grabbed it.

“This isn’t my Bluey cup. Or a water bottle.”

“No, but it won’t spill.” he was glossing over the fact that it was a bottle. You glared, looking at the plastic thing with the silicone nipple. It was filled with some juice, and you wre thirsty. But this was too much.

“No, Eijiro.”

“Hey,” he frowned. “That’s not what you call me, is it?”

“Fine!” you huffed. “Daddy. I don’t want this.”

“I thought fucking you stupid would help you with fussing.” he chuckled. “Come on, baby, it won’t spill, you’re tired and thirsty. Just lay down. No one is home to care.” you sighed, knowing that you weren’t going to win the battle.

You took the bottle. It was decorated with butterflies, and it was kinda cute, you thought. For all that it was a baby bottle. You sighed and put the nipple in your mouth, working out how to drink from it. The juice was sweet and cold. Eijiro’s hand was heavy and warm on your head.

“This is comfortable.” Izuku noted as he stepped inside. He noticed how zoned out you were and smirked when he saw the bottle.
“What’cha got there, babes?”

You whined, turning your head into Eijiro’s thighs, not wanting to talk about it. He laughed, coming over to rub your back. Eijiro coaxed your head back to look at Izuku. He smiled and squatted down to your level. His hand went to your hair and you pressed into it.

“Tell Daddy what you have, babes.”

“A bottle.” he nodded in interest, clearly waiting for you to elaborate. “Daddy gave it to me. Because it–it won’t spill.”

“Very smart.” he tapped your nose. You giggled and popped the bottle back in. Izuku stroked your hair as you drank.
“Well, go back to having your cuddle, angel. We can go to bed together later tonight.” you didn’t catch the wink he gave Eijiro.

Chapter Text

You were so sweet when you were asleep, Hanta thought. You were in his bed, your arms around Denki’s waist. Your head was on his chest, one of his hands reached up to cup the back of your head. His face was pressed to your forehead.

Precious, Hanta thought. He rubbed the towel over his damp hair, watching the two of you. He dropped it to the side, creeping towards the bed. His lounge pants were slung down low on his hips, and they were easy to shimmy out of.

“Han?” Denki mumbled. He was hushed with a press of lips to his, his eyes just barely opening. He watched with interest as Hanta made his way to you. He reached between your legs, patted your diaper.

“Ah, good she’s dry.”

“What’re you doin?” Denki yawned.

“Be quiet, love. Pull down your pants and underwear.” Denki seemed more awake then. He eased down his own pajama bottoms, careful not to wake you. You did whine a bit, burying your face in his chest. Hanta pulled your blanket around your shoulders, leaving your waist and legs uncovered.

“Missed you.’ Denki whispered.

“Not nearly as much as I missed you.” he said, sincerely and openly. Denki’s cheeks went pink, like they always did when Hanta was looking at him like that, Like Denkii was the only thing that kept his life lit up.

It wasn’t easy to manuever around, but Hanta managed. He reached for the tapes of your diaper, undoing them and pulling down the back. You mumbled in your sleep, hand going back to bat at him.

“Hush, baby girl.” Denki reached for your hand, holding it. “You’re fine, you’re fine. Go back to sleep.” he kissed your forehead, and it was easy for you to ease back asleep. He reached for your pacifier, since you always managed to let it fall out of your mouth, and popped it between your lips.

“Now that the baby is gonna be quiet.” Hanta mumbled. He gave his erection a few pumps and spread your legs.

“You feeling needy, Hanta?” Denki asked in a sultry tone. “You need a little something from our girl?”

“From you, too.” Hanta’s eyes seemed to glitter in the darkness. Dangerous, Denki thought, like an animal that would follow you in the darkened woods. He gave a happy shudder, watching intently.

Hanta rearranged you a bit, keeping the diaper under you. He gave one sharp thrust of his hips, entering you without any pretense. You gasped in your sleep, your face going hot against Denki’s skin.

With another hand, Hanta grasped his lover’s dick. He pumped it in time to his rocking into you. This wasn’t a harsh fucking, he thought to himself. This was a little good night hump. This was something sweet to make everyone a little more comfortable for sleep.

Denki was biting his lip, trying to keep from arching his bag. It was hard for him to be quiet, it was hard for him not to beg, not to moan or groan. You were suckling on your pacifier, any murmurs were muffled.

Hanta continued to rock into you, a gentle sway that matched the way that he was playing with Denki. Denki used one hand to play with your hair. The other one was locked around Hanta’s hand, as though he were afraid it would leave and he wouldn’t get off.

Precum leaked from the head of his cock, slicking him up. Hanta’s mouth watered, wanting so much to lick it off, open his mouth wide and have Denki fill his mouth with cum, bitter and tasting of love. Everything he needed in the world.

You moaned, head lifting up when the dark haired man was fucking you a little harder. Your eyes were opening as your body moved at his pace, taking everything that he was willing to give you. You backed your ass into him, wanting more even before you understood exactly what was happening.

“Daddy?” you mumbled.

“We’re here, we’re here.” Denki assured you breathlessly. He tapped on your pacifier, encouraging you to suck on it. Your hazy eyes looked at him with adoration. Hanta groaned, feeling you go tight around him.

“Are you gonna cum?” he demanded, looking at Denki. “You gonna make a mess all over my hand? We have those warm wet wipes, it’s okay if you do.”

“Don’t talk like that.” Denki’s face went pink again. His legs spread wider.

“The baby is gonna cum.” he said. “She’s gonna cum all over me. And then I’m gonna cum inside of her. I haven’t decided if I’m gonna tape her diaper up, or make her piss in it for me.’

“Make her sit in it.” Denki licked his lips. “Make her spend the whole night in your sticky cum.”

“Was she a bad girl?” he teased.

“No,” Denki was a little breathless. “I just like the idea of her sitting in your filth all night. I want her to have to deal with it until… until I change her in the morning.”

“You’re so cruel.” Hanta chuckled. You pushed your ass back more, and the dark haired man bent his head and bit your shoulder. You came howling, pacifier dropped out of your mouth. And Denki wasn’t far behind, sticky cum spurting over his lover’s hand.

“Goddamn, that’s so beautiful.” Hanta grunted, cumming inside of you. He moved his hand and wiped it against your diaper, taping it back up. He patted your ass. You were breathing hard, letting Denki coddle you for a moment.

The blond watched Hanta limp dick between his legs as he went to the wipe warmer. He wiped his own hand and then came for Denki. He moved gently, carefully, as sweetly as he did when he changed your. He held Denki’s penis in his fingers as he wiped below his balls for good measure, leaving him perfectly clean.

“There,” he looked satisfied, throwing the wipes away. You were mainly asleep again as he climbed into bed, winding himself around Denki. Denki was giving him the same besotted look as he rubbed your back, hoping to keep you quiet.
“You liked that, Denks? You liked getting attention same time as our baby?” he purred. “Should we try and baby you?”

“No,” he snorted. “I just like knowing that I’m going to get attention.”

“Of course,” he cooed, kissing his cheek. “The two of you need to be asleep now.”

“It’s a hot day.” Eijiro glanced at you in the rearview. “You don’t want to get all dried out and thirsty, do you?”

“I’ll be fine. I know when I need a drink.” you huffed. You leaned against your window. This was a stupid idea, you thought. You should have stayed home. But everyone was busy, and this was a day trip to get some special made equipment for Denki. No one wanted to leave you home again.

“You’re getting fussy.” Denki noted. “Are you sleepy, babe? Is that it?”

“No! I’m allowed to not like something and not be called fussy. Would you like it if someone called you fussy and said you needed a nap everytime you didn’t like something?”

“Someone should tell Bakubro that.” Eijiro muttered. Denki snickered. The two of them seemed to have forgotten about you in the backseat. Good, you thought. You drank from your water bottle, blanket spread over your lap. You supposed you did look sort of like a little kid, sitting there in the backseat, with your puppy and your blankie.

But there was no one else around, so who cared?

You turned pages in your book, sipping idly. It wasn’t long before you felt that pinch in your bladder. You shifted a bit in the seat, hoping to alleviate the pressure. But that didn’t help. You were, of course, padded. Still, you thought. Intentionally peeing in the car? That was a step too far.

“Can we stop?” you leaned forward and tapped Eijiro’s shoulder.

“Mmm? Something wrong?” he asked.

“I um… I need to visit the washroom.”

“Oh! Well, sorry hon. Next stop isn’t for about twenty minutes.”

“Oh,” you felt the color drain out of your face. Denki turned his head to glance at you, a little worried.

“Are you okay?”

“I’m fine.” you mumbled. He looked concerned, but went back to his chat with Eijiro. The first five minutes weren’t too bad. The next five minutes were excruciating. You whined, pressing your hands between your legs, like that would help.

“Babes, if you have to pee, just pee.” Eijiro glanced at you again, “That is literally why you are wearing a diaper.”

“I don’t want to!” you snapped. “I want to use the toilet.”

“What makes you think we were gonna let you anyway?” Denki asked casually. You gasped, staring at him.

“Daddy’s right,” Eijiro nodded. “Rest stops are filthy, lovey. Wouldn’t want you sitting on those seats.” he shuddered.

“You use them!”

“We stand to pee pee.” Eijiro was hiding a smile. “But not you. You’re just a baby girl, and you need to sit.” you were rocking in the seat. Denki unbuckled himself and climbed over the console to the backseat.

“Come here, love bug.”

“Go away!” you snapped, pushing at him. The ache in your belly was nearly unbearable. “Go away!”

“That’s not nice. That’s how I can tell you're sleepy. You’re always so cranky.” he chuckled. You tried to curl away from him. But you were in the car, and where the hell was there for you to go. Denki scooted in close, pinning you against him and the door. He wound an arm around your shoulders.

“Stop! Please!” you whined. “I don’t want to, I don’t want to.”

“Hush,” he soothed, one arm going to your belly. You tried to bat him away, but he didn’t seem phased at all. He pushed at your stomach, humming softly.

“Daddy,” you begged. “I can’t…”

“You don’t need to.” he shrugged. He pressed down hard. You yelped, feeling your bladder give. His hand moved from your belly between your legs.
“There it is. Oh, you had to potty so bad, didn’t you? Poor thing. You could make yourself sick holding it.”

You were sobbing as relief flooded you. You felt the diaper expanding, making it harder for you to bring your legs together. You swiped at your eyes, trying to calm. Denki had moved to rubbing your belly now.

“She all done?” Eijiro asked.

“Mmhmm, diaper is soaking wet. Good thing she didn’t wait longer, she would have leaked.” he laughed softly You moaned, embarrassment clawing at you. Of course, Eijiro pulled into a rest stop just then. Denki scooted back to the other side of the backseat, pulling your shoulders down until your head was in his lap.

“All right,” Eijiro went to the trunk, bringing back a seat pink bag that seemed to follow you everywhere. He opened the door you had been leaning on and set the bag down on the ground. He rummaged through, holding up a diaper.

“Can’t we do it inside?” you whined, pointing at the building with the toilets. “People could see!”

“I already told you, it’s filthy in there. We’d have to disinfect everything, and I don’t want to risk you getting sick. And if you sit too long in wet panties, you’re going to get a rash. And that’s no good, is it?” he pushed your dress up. You had tolerated it because you knew no one would see while you were riding in the car.

“Stop,” you whimpered. Eijiro rummaged in the bag again and came up with a pacifier, giving it to Denki. Denki pressed it to your lips. Even when you had accepted it, he kept his fingers on it, tapping gently. You looked up at him with big wet eyes.

“It is almost nap time, huh? Can’t expect a baby to spend a whole long car ride happy. Poor thing. You were lonely, weren’t you?” he rubbed your forehead, letting his fingers skim down your eyelids, encouraging them to close.

Eijro was wiping you clean, lifting your legs. It was easy for him to slide the diaper under you, sprinkle down a healthy amount of powder. He taped you up and eased your skirt down. But when you went to sit up, he left a hand in the middle of your chest.

“No, Denki’s right. You’re tired. You need a nap.” he grabbed your blanket and covered you. You rolled in the seat, pressing your face to Denki’s thighs. He rubbed your scalp, tucking puppy in next to you.
“Aww, love bug! Don’t be sour at me.” he frowned. “I hate it when you’re upset.”

“She’s not sour at you, Eiji, she’s just sleepy.” Denki smiled. The red head leaned in to kiss the blond, somehow managed to lean down and kiss you.
“She’ll be fine when she gets a little sleep.”

Eijiro closed the door and went to the driver’s seat. You snuffled a bit, wiping your damp eyes on Denki’s jeans. He made hushing sounds. Soft music came from the radio then, gentle piano music.

You’d tell them after your nap how upset you were, you decided.

Chapter Text

“I don’t like going out in my diaper.” you frowned as Katsuki was gathering jackets. He raised an eyebrow at you before he slipped down to his knees. You were still moving towards him robotically as he held out of your shoes. Both of you were quiet as he put your shoes on and tied them up just right.
“I know you don’t.” he put his hands on your shoulders. “But your opinion is just not necessary right now.” he stayed on his knees as he helped you into your jacket and zipped it up for you.
Katsuki had put you in a skirt that was on the short side. You fussed with it, pulling down at the hem. It covered your diaper, but not by much. You squirmed, uncomfortable. With a sigh, you realized Katsuki was carrying the pink diaper bag, tossed casually over his shoulder.
It was almost a funny sight. He was so masculine, so big, so strong, so brave. And here he was with that pale pink back with the white piping. You knew for a fact that no one would be able to say anything to him about it.
Katsuki put on his ball cap and sunglasses, walking you to the car. You were surprised when he opened the front door and let you climb in. Still, he reached for the seatbelt and clicked it on for you, stopping to brush a kiss to your cheek.
The skirt was kind of grown up. He was letting you sit up front, like a grown up. Maybe, you thought, just for once you could pretend to be big on this trip. You were on a shopping trip with your boyfriend. Nothing weird about that.
You were even more secure in this when Katsuki left the diaper bag in the car. Instead, he held your hand. When he had first begun doing this, he said it was because your stride was so much shorter than his. But now, you thought he did it because he liked to hold your hand. And, well, you liked having your hand held.
The trip was mostly boring. Katsuki stopped at a home improvement store, looking at the outlet covers. You daydreamed a bit, looking at the pretty hanging light displays. You’d always loved that about hardware stores, you thought.

“Oi,” Katsuki said, snapping you out of your dreamy thoughts. You startled and looked at him. He was smirking, though you weren’t sure why. Did he really need a reason?
“Come on, baby.” he pitched his voice in that sweet, sing song voice that Izuku would use for you.

“Don’t,” you hissed as he took your hand, walking you to the register. “People can hear.”

“I know they can.” he shrugged. “And I’m not the one bothered.” you scowled, sulking as he paid. You were barely paying attention when he bought a lollipop. As you walked out of the store, he unwrapped it. But instead of placing it in his own mouth, he held it to your lips.

“Huh?”

“You’re pouting and upset. Usually, at home, we give you a paci when you feel like that.” you felt your lips twitch at the mention of a paci. “Unless that’s what you want? I’m sure I can find a shop here.”

You shook your head frantically and opened your mouth. Katsuki pressed the round, sugary treat to your tongue, giving you a knowing look when you clamped your mouth around it. You wanted to keep giving him dark looks, but it was a yummy treat. And it was nice to have something in your mouth.

You fiddled with the hem of the skirt while Katsuki walked you into a department store. He had mentioned upgrading the television in his and Izuku’s room. You walked to the electronics as he pondered them, swirling your tongue around the lollipop.

You felt that pinch in your bladder. You shifted your weight. You could tolerate it. Katsuki was walking so slowly between televisions. He always was so thorough, you thought scornfully. How different could they be? The same size, same HD4K or whatever people were excited about.

As long as he made up his mind, you thought, you could make it home to pee. He must be intending for that, you thought. Since he didn’t bring in the diaper bag. You wriggled a little in place, sucking harder on the candy.

“What’s your problem?” he barely glanced at you. You felt heat rising to your face and shook your head. If you didn’t name it, it couldn’t control you. He went back to the televisions. He was moving so slowly, careful measured steps. Once you got to the end of the row, you breathed a sigh of relief. But he turned and went right back, looking them all over again.

“Kacchan,” you said softly.

“Hm?”

“I need to pee.”

“Okay,” he shrugged, not bothering to give you any attention. You whined and reached for his hand.

“So let’s go home.”

“Why the fuck would we do that?” he released your hand, gently. “I’m still shopping.”

“Please,”

“Are you or are you not in a diaper?” he quirked an eyebrow. “Because now is the time to tell me if you’re not.” you nodded slowly. He shrugged again.
“Sounds like you’re fine then.”

You threw your whole self into holding it. You pressed your thighs together, then crossed your knees to keep your legs together. Katsuki didn’t even look at you. You whined behind your lollipop, your hands going to your groin.

It was a losing battle. You let out a muffled sob as you felt a little dribble into your diaper. And then it was like a dam burst. You were pissing, sweet relief filling your body. You felt someone come behind you and lift your skirt.

“Well, well, well, looks like I made the right choice in having you diapered today, didn’t I? I thought you could make it, so I didn’t bring in the bag. Too bad,” he clicked his tongue. “Because if you could have made it, we could have talked about big girl underwear.” his hand went between your legs, feeling the diaper swell as you kept peeing.
“Not ready for that, are you, baby?”

“Kacchan,” you whined.

“You about finished?” he asked. You reached behind you to yank down your skirt, eyes darting to make sure no one was around.
“I asked a question, babes, you better answer unless you want your ass spanked right now.” he warned. “Because I will do it.”

He would, too. You knew he would. You let out a shuddery breath and gave a slow nod. But the bag was out in the car. Where was he going to leave you while he went to grab it? Panic spread through your chest.

“Good girl.” he whispered in your ear, smoothing down your skirt. “Aww, you pee-pee’d so much. Your diaper is peeking out of that tiny skirt.”

You whimpered at this. He walked you past a reflective service, and you could see it was true. The littlest peek of your diaper was visible. You buried your face in your hands. Katsuki laughed, a sound that sent shivers down your spine. He grabbed a television, the first one he’d started to look at.

“Let’s go, doll.” he walked towards the registers. You trudged behind, trying to hide yourself. You were grateful for the lollipop. At least your quivering lip was hidden. You tried to hide most of your body behind Katsuki.

At the register, he picked another lollipop. He refused to let you hide behind him as you walked out of the shopping center. You felt the squish of your diaper, tears running down your cheeks. This time, Katsuki opened the backseat and steered you in, buckling you up.

You cried the whole way home, sniffling around your lollipop, wiping your eyes. Why had he even brought the diaper bag, then? What if someone had noticed? Someone probably did! A stranger knew you wore, and pissed in, a diaper.

“Enough, you’re fine.” Katsuki parked the car. “Come on, let’s go inside and get a dry diaper on.”

“No!” you pulled out the lollipop. “I don’t want to do this anymore. I don’t want to wear diapers and be dragged around, I’m not a baby! I’m not!” you were raising your voice. Katsuki said nothing as he came to open your door and help you out.
“Stop!”

“Hey,” his voice was low and dangerous. He caught your chin in his hand, keeping your gaze directly on him. “That is enough.” his grip was strong, almost painful. You took in a few hiccuping breaths. Katsuki didn’t release you until he was sure you stopped screaming.

You trailed after him into the house. Once the door was closed, you turned towards your playroom, hoping to hide. But he had you by the elbow. He wasn’t pulling you, exactly, but he wasn’t giving you much of a choice.

You howled and tried to pry him off you. Katsuki said nothing, continuing to walk you to the room he shared with Izuku. You were laid on the bed. With a scowl, you began to kick at him, hoping he’d back off.

Heavy hands landed on your thighs, pinning them down.

“Stop it.” he said it so firmly, with so much authority. Like he knew that you’d obey as long as he was firm enough. You crossed your arms to pout as he moved, pushing up the skirt and taking off your wet diaper. He strapped you into a new one with plenty of powder and discarded the skirt, sitting you up and unfolding your arms to peel off your shirt.

You fully expected to be laid back out on the bed with one of Izuku’s pillows while he grabbed your blanket and puppy. Or maybe in the crib. Either one was fine with you! After all, you wanted to be away from him.

Katsuki had settled you on his hip, stopping at your crib to get your items. You didn’t dare struggle, but you made it clear you didn’t want to cuddle. Katsuki didn’t care, dropping into a recliner and kicking out the footrest. He reclined and arranged you straddling his lap, your chest pressed to his.

“Still pissed off? You’re cranky because it’s nap time.” he noted.

“No, I am upset because you’re not listening to me and you embarrassed me. In public!”

“We told you we make the rules.” he shrugged. “You said you wanted it to be over. But face it, babes. You were awful at doing things like… having a job that paid all your bills.”

“You’re being mean, Katsuki.” you sounded childish as you said it. But it was the truth! He was being mean. And harsh. And cruel. And it was hurting your feelings. Katsuki cooed, covering you with your blanket and pulling you to rest your head on his shoulder.

“I know it seems mean.” he kissed the side of your head. “But it’s for your own good. Aren’t you happier being my baby?” you didn’t answer. Katsuki laughed softly under his breath, reaching into the side table drawer and pulling out a pacifier. He slipped it in and cuddled you close.

You hadn’t wanted to cuddle. Didn’t even want him to touch you. But he was maneuvering his shirt off and pulling you back in. So you were skin to skin with him, feeling his heartbeat against your own skin. His hands were under the blanket, skimming up and down your back. You rested against his shoulder, sucking on the pacifier. He was so warm, so comfortable. And Puppy was tucked into your arms.

“Just need a rest, huh? Today was a lot.” he hummed to you. “I’m sorry, baby. I wasn’t thinking clearly. Kacchan’s fault, not my baby’s fault.” you snuffled a bit to let him know that you were still bothered. He chuckled and kissed your cheek.
“Sit with me, you’ll feel better.”

You didn’t fall asleep, but remained with him in the recliner. He had put on a television show, but you were content to be snuggled and calm, your body warmed by his. When the door opened, the others immediately began commenting on how sweet it was.

“Shut the fuck up.” Katsuki said without any heat. “My baby and I are having time together, and you’re ruining it. Be quiet or go away.”

Gradually, everyone drifted away, only to come back and take up space in the living room. Denki made some rumblings about wanting to snuggle, but Katsuki ignored him. You let your hand press against his chest, satisfied when he covered it with his own.

Maybe you did belong like this.

Chapter Text

“Where did you get that?” you asked, eyes wide at the newest contraption. It hooked into a doorway, the harness dangling on what looked like bungees. It was like one of the jumper things you’d put a baby in.

But it was sized for an adult. Like you.

“You’d be surprised what you can find online!” Denki chirped. You were beginning to believe you wouldn’t be surprised at all. He held out his hands for you.
“Don’t’cha wanna try it?”

“No,” you scowled. Denki picked you up, not caring one way or the other. That should not have come as a shock to you, not really. Why did they even ask like it was an option? You were sulking as he laid you on the couch and grabbed a fresh diaper. You were still and quiet as he undid the one you were wearing. But instead of sliding the fresh one under you, you heard the click of a bottle.
“Huh?”

“Hush, baby.” Denki cooed. “You’re fine.” cold lube was gentle pressed into your cunt. You gasped, arching away from it. Denki clicked his tongue.
“No no, stay where I put you.”

“What are you doing?”

“You don’t need to ask questions. You only need to do what we’ve asked you to do.” he soothed. More lube and another finger was at your ass. You whined at the stretch, the burn. It was rapidly becoming nearly too much.
“It’s all right, shhh,” Denki soothed.

“Oh, you’re prepping her?” Hanta grinned devilishly. “Want some help with that?”

“Will you take her hands? She’s a little squirmy, and I don’t want her grabbing anything. Keep her on the couch for me?”

“Of course,” Hanta approached, kneeling next to the couch and laying across your top, your wrists pinned up by your head.
“Hi, baby.” with him in the way, you couldn’t see what Denki was doing. It was terrifying and also titillating.

“Please,” you whimpered, unsure what you were even trying to ask for. Hanta nuzzled your cheek, pecking kisses here and there. The fingers were still inside of you, moving, opening you up with practiced grace.

There were times you adored the fact that they knew your body so well. There were times when you wanted to curse them for the knowledge. Your hips were moving, ready to ride those fingers, so skillful and nimble. Denki snickered as Hanta reached to kiss you.

Your lips crashed together again and again, his tongue licking into your mouth. You hummed against him, wanting something, uncertain how to vocalize it, if vocalization was even going to be an option.

Hanta kept you distracted, his thumbs rubbing the soft underside of your wrists, his mouth worshipping your lips. You chased his mouth, wanting more and more, riding on Denki’s fingers. Just when you were able to forget exactly what was happening, Denki moved his hands.

You whined, opening your eyes, teary and confused.

“Cry baby,” Hanta teased. You sniffled until you were interrupted by feeling something pressing into you. Two somethings, actually. Goddammit, you thought, where had they found those stupid egg vibrators that Eijiro bought?

“There we go.” Denki taped up a clean diaper and snapped your onesie. He lifted you up to carry you to the bouncy seat and carefully threaded your legs through. The vibrators weren’t on, but you were aware of them, especially when you were fully seated. You gasped, squirming in the seat.

“Aww, baby love!” Denki kissed the top of your head. “Are you confused? Want me to show you how to do it?”

“I know damn good and well–.” you began. He clicked his tongue and a pacifier was pressed into your mouth. You glared, ready to spit it out. But just then, the vibrators inside of you buzzed to life. You gasped, letting the harness take your full weight.

“There you go.” Hanta praised. “Good job. Bounce your legs, babe.” he grabbed the harness and began to bounce it slightly, raising you on your toes and letting your weight fall back onto your heels.

Fuck, you thought. If that didn’t do things to you. You whimpered and continued to bounce, feeling the vibrators rub up against the best places inside of you. You sucked on the pacifier, grateful for something in your mouth as you leaned back in the harness bouncing in smaller, faster bounces.

“Such a good girl.” Denki smiled, kissing your forehead.

And they left you like that. You bounced in the harness. But every time you were close to orgasm, just before you could push yourself over the edge, the toys would flick off. And you were snapped back to reality.

You lost count of how many times this cycle spun through. You were a whimpering mess, tears oozing down your cheeks. The door opened and you turned your head to see Eijiro walking in. He smiled at first, then frowned to see you so upset.

“What’s wrong babes?” he dropped down to fold his legs and sit in front of you. The buzzing started again and you moaned, pacifier falling out of your mouth, a line of drool trailing behind as your eyes rolled back.
“Oh, are Han and Denks tormenting you? Poor baby.” he held out a hand, palm up, and the remote was placed down.

Eijiro put his hands on the harness and bounced you gently, looking at your face. You moaned and whimpered, the pacifier rolling towards the floor. He caught it easily and set it in his lap. There were more important things to worry about right now, he thought. He clicked up the intensity, hearing you moan. It was so raw, so guttural, the hair on the back of his neck stood up.

“Is that it, baby girl? Are you close? You gonna make a mess for me in that diaper? Gonna be all sticky and wet for me to change?” he teased gently. “Oh, you’re so close. You’re right there, aren’t you? Come on, cum for me.”

You moaned again, toes curling against the floor.

“Fuck,” Denki whispered, seeing you clutch the bungees as you came, screaming, finally reaching your peak. You collapsed into the harness, eyes blurry, teardrops clinging to your eyelashes.

“Oh, good girl. Such a good girl.” Eijiro whispered. He lifted you up, trembling, from the harness. You whined, the touch feeling too much. You were covered in sweat, panting. He hushed you and laid you on a change mat on the floor.
“Denks, hon, can you go and get me a warm damp towel. Baby needs to be sponged off a bit, I think.”

Denki scurried away. You didn’t notice the erection pressing painfully against his jeans. He was back in a moment with the towel. Eijiro steered you out of the onesie and wiped you down all over. He paid special attention to your face, smiling sweetly when you blinked slowly at him.

“She really is happier when we keep her all dicked down, isn’t she?” Hanta mused.

“She’s just our brainless baby!” Denki dropped down next to you on the floor. “And we can take care of her.”

“You feeling some kind of way?” Eijiro smirked. Denki nodded, shimmying out of his pants. He set your naked body on top of him. He loved when you were so thoroughly cum drunk, he thought blissfully. You were so malleable, and he was able to sink inside of you. You keened, bordering on overstimulation.

“Let me help.” Ejiro situated himself next to you. He kept your weight and set to moving you up and down. Denki’s hands were on your hips, helping guide. He must have been pent up, because it didn’t take too long before he moaned, long and low, and you felt him spilling into you.

“Guess you cleaned her up for nothing.” he chuckled a little sheepishly. Eijiro shook his head, pulling you easily off the blond as you rag dolled against his chest.

“Nah, she was all clean for you to enjoy. I’m gonna take a bath with her. Want a bath?” he asked you in a sweet, high pitched voice. “We can play with your duckies and your whale!” He carried you, naked, to the bathroom. Your head lolled on his shoulder, too drained and satisfied to do anything.

Eijiro mentally congratulated all of them on such a fine purchase.

Chapter Text

“No!” you whimpered.

“It’s nothing that can be helped.” Izuku said patiently. “I am so sorry it makes you uncomfortable, sweetheart. But you’ve shown us that you can’t handle being here alone. You don’t even like being here alone.” he smoothed your hair down and then cupped your face in his hands, thumbs wiping at tears.
“Wanna sleep with me and Kacchan?”

“I want you to not go! Why do all of you have to go?”

“Because that’s what happens sometimes, sweetie.” he looked as frustrated as you felt “I am sorry, and I wish there was another way.” he picked you up. You locked your legs around his waist as he swayed.

“Aww, babes.” Eijiro sounded just as sad as you. “We’ll be as fast as we can.” he put his hand on your back, rubbing in circles. “Don’t cry, you’re gonna break my heart.”

“Enough,” Katsuki took you from his husband. “Settle down. You don’t have to like it, you do have to live with it. We’re going to get you some baby sitters, and they will be people we trust. And we’re counting on you to be a good girl while we’re gone.”

“Maybe you should stay home and make sure I’m good.” Katsuki raised his eyebrow and you knew that was pushing the envelope. Instead, you put your head on his shoulder. He carried you to his room, laying you on his bed.

The two days before they left, you clung to them. You would be in Eijiro’s lap, sprawled across Denki in bed. You insisted on sitting with Sero for meals, fed from his fork and his plate.You slept with Izuku and Katsuki, ignoring your crib.

But the day came. You couldn’t believe there was a mission that required all of them. You stood in the living room as they gathered their bags. You were passed from arm to arm, kissed and told how loved you were.

“Please stay.” you said one more time. Denki looked on edge, close to saying yes, ready to give in. “Daddy, please stay with me.” you wrapped your fingers in his shirt, certain that was going to be what sealed it.

“Enough of the eyes,” Izuku took you. “You know Daddy can’t stand that.”

“Of course she does.” Katsuki snorted. “That’s why she was using them on him. She figured she had the best shot.”

You really hated it when Katsuki could have you figured out. You pressed your face to Denki’s neck, not looking up when the door opened. You didn’t want to see whoever it was, didn’t want to consider what could happen.

Your heart was beating fast. Denki kissed the side of your head, whispering sweet nothings and encouragements to you as there were greetings murmured. You whined when you heard Izuku and Katsuki begin to rattle off instructions.

“She’s meant to sleep in her crib, but the past few nights she’s been in bed with us. You can do whatever she’s comfortable with.” Izuku said, tapping his chin, trying to remember.

“Don’t be afraid to give her a spanking and put her in time out.” Katsuki added. “It does a lot for her bad attitude.”

You lifted your head to give him a devastated look. You turned your head then and saw the two men. One with long blond hair and a bright smile. The other had dark hair, threaded with strands of silver. He wore an eye patch and had his arms crossed.

“We’re so grateful to the two of you.” Eijiro said as he picked up a few bags and paused to kiss your cheek.

“Retirement has left us with some time.” the dark haired man said. You had a sneaking feeling you were supposed to recognize them. The blond was helping Sero with some of the bags as they headed out.

“Now hand over the baby.” the blond looked at Denki. “Come here, gorgeous. Aw, no need to play the blues.” you found yourself in someone else’s arms.

“Thanks, sensei.” Denki murmured. It clicked for you then; this was Aizawa and Yamada. Eraserhead and Present Mic, now retired. They had taught them in school. You swallowed hard, remembering all the stories about Eraserhead that you had heard.

“Be safe,” Aizawa put his hand on Denki’s head, and for just a moment, you were given a glimpse of the children they might have been. You saw, for a heartbeat, the life they had before you knew them.

“Aren’t you pretty?” Yamada cooed to you, bouncing you slightly. “We’re going to have such a fun time while they’re gone.” you glanced at Denki as he left, and you could see him fighting the urge to turn back to you.

But the door closed, and you heard the car start. You stared at the door, shocked they had actually left you. You turned to look at the blond, with his green eyes that were looking at you kindly, but seemed to hold something in them you could not name. Something that sent a chill through you.

“Got her all to ourselves, don’t we?” Aizawa said calmly.

And you burst into tears.

***

“Oh, baby, baby, no.” Yamada was trying to rub your back. You shoved your hands at his chest, trying to squirm away from him. You wanted to run to your play room, hide there and try and sort things out.

“Here,” Aizawa held out his arms. You were placed in them, still sobbing. He adjusted you so that you were eye level with him.
“Enough,” he said in a firm voice. There wasn’t any anger or heat there, but he said it with the air of someone who was used to being listened to without question.

“I want my Daddy.” you said.

“And they had something to do.” he shrugged. “I understand that you’re upset, you are going to have a very bad time.” he said it matter of factly. There wasn’t a threat there, only a simple statement of truth.

“Sho…” Yamada said.

“No,” he said calmly. “We have to show her we mean business now.” he began to walk towards the bedrooms. “Here,” he opened the door to Izuku and Katsuki’s room and set you in your crib.
“You can take some time to calm down.”

“No!” you stood up, gripping the bars. “No! No!”

Aizawa didn’t say anything else. He walked out of the room. You howled, ratting the side of it. Yamada came in and put his hands on yours.

“I don’t know how you act for your daddies or what they tolerate.” he said gently. “But I would encourage you to think hard and make good choices.”

That did not make you feel better.

Chapter Text

You stopped sobbing eventually. Aizawa came back in, looking at you in the crib. You had plopped down to your bottom, wiping your eyes and feeling pitiful. Neither of you spoke for a few moments. He reached in and picked you up, plopping you on his hip.

“Your pants are dry.” he noted, patting your bottom. You groaned, not loving that. You didn’t whine, though, and Aizawa carried you to the living room. Yamada lit up when you appeared. He held out his hands, as though it were a given that you would be handed over to him.

“Calmed down, dolly?” he cooed, letting you sit in his lap so you were facing him. He bounced his knees a little, enjoying seeing you jiggle in his lap. “What had you so worked up? Separation anxiety?”

“I’m sure she doesn’t even know what that is.” Aizawa snorted. You scowled at him. You did too know what it was! But Yamada had reached to your belly, giving a little press. You gasped and whined, wanting to wriggle away.

“Oh, I get it! You’re all uncomfortable because you have to go pee!”

“No!” you protested.

“Think about it.” Aizawa crossed his arms. “Are you going to try and keep yourself from going pee until your daddies come back? That could be a long wait. And we told them that we’d take very good care of you.”

“I know,” you said slowly.

“So we’ll do that.” he said it smoothly and calmly. You couldn’t think what he meant. Yamada handed you off and Aizawa had you again. You wrapped your arms around his neck, playing with the strands of his hair.
“You trying to be cute, hm?” you didn’t respond, wondering if that would help. He said nothing, but the sound of a zipper being pulled down and a belt being unbuckled caught your attention. You glanced over and saw that Yamada had lifted his hips and was pulling down his skinny jeans.

His dick sprang out. Long and on the thin side. He grinned and winked, wrapping his hand around it to give a few pumps. You blinked in confusion. Aizawa took you back over, laying you on your side with your head in Yamada’s lap, facing him. The tip of his cock was almost touching your nose.

“Open wide, sweetie. And I know you know better than to use your teeth, don’t you?” there was the of a warning lacing the words. You whimpered as he gripped his dick, tapping your lips with it.
“Oh, there you go.” he praised when you slowly parted your lips and opened your mouth, allowing him to slide in.

He was a little saltier than your daddies, you thought. And he wasn’t as patient. He thrust in almost immediately, touching the back of your throat. You coughed and gagged. Yamada made a sympathetic sound, patting your back and rubbing between your shoulder blades.

“Take it slow, baby. Relax your jaw. Oh fuck, there it is.” he groaned, his head falling back when he felt you relax and take him deeper.”

“She just needed something in her mouth? I should have figured that out.” Aizawa sighed. He parked it in a chair and grabbed the remote, seemingly ignoring the two of you. You wondered what this had to do with peeing. It didn’t seem to matter, but you did like knowing that there was something you could do to make them happy.

Even if it was a blow job. And even though the only ones you really liked blowing were your Daddies. Yamada’s hand snaked between your legs, hand going to your ass to begin rhythmic patting. You looked up at him awkwardly.

“Now you’re happy, aren’t you? And once you pee, we’ll get you in a dry diaper and we can play whatever you want.” you were confused. Yamada gave your diaper a little squeeze and you squirmed, pressing his arm between your thighs.
“Go pee-pee for me.”

You whined. If you sucked harder, sucked better, maybe he would forget it. You went faster, bobbing your head even though it was such an awkward angle. You heard a shuffling, realized Aizawa was coming over. He put his hand on your head, petting over your hair.

“I can help her.” Aizawa said quietly. You wanted to speak, to protest. But neuter of them even glanced at you.

“Might be for the best. I know the boys said she could get fussy. But I don’t want her to spend the whole time so unhappy. And I know having to pee isn’t helping her mood.” he patted your bottom again. A hand was there, rubbing your lower belly.

“You’re so tense.” Aizawa clicked his tongue. “And I don’t see why. You’re just a little baby, and all you have to do is what we tell you.” He had a hand on your head too, and applied just the slightest bit of pressure.

“Oh, fuck, she went tight. Her throat is just squeezing me.” Yamada grunted. Aizawa rubbed and then pressed again. You kept your thighs clamped together.

“I know you have to.” Aizawa continued in a low voice. “Get it over with so I can get you all wiped up and we can get you in a dry diaper. And you’re going to feel so much better.” you whined again and Aizawa pressed hard on the sensitive part of your belly.

“There she goes.” Yamada moaned as you let out a punched out sound. He pressed hard against your diaper as you began to piss. Aizawa didn’t let up the pressure, and your head had been shoved down. No one was letting you move, locked in wth the tip of his dick pressed almost too far down.
“Oh, that diaper is swelling so much, and it’s so warm.”

“Is it?” Aizawa gave it a squeeze. “That must have been making you moody. You can’t hold it, my dear, it’ll make you sick. And we’ll have to do whatever we can to keep you healthy.” he warned. You wondered how much worse this could be.

Once you started pissing, it was hard to stop. You emptied your bladder into your diaper. Yamada grunted twice, and the bitter taste of cum flooded your mouth.

“Keep it in your mouth.” Aizawa warned as he took you off his husband, who was limp on the couch, panting. You looked at Aizawa, desperate, as he sat you on the ground. He grabbed a bib and tied it around your neck.
“Let it go.”

You made a weird sound, shaking your head. He bent down, one hand on his knees as his other hand pinched your cheeks. Your eyes went wide, trying to breathe through your nose. The two of you had locked gazes again.

“Let. It. Go.” and cum and drool oozed past your lips, dripping to your chin and making the bib wet. Aizawa looked satisfied and coaxed you into laying down, spreading your legs and opening another diaper.

He moved with a certain practice. You wondered if he’d done this before. When you were wiped, had some cream put on, and powdered, you were sure he had. He sat you up and used the bib to wipe at your chin, getting the rest of the mess off you.

“Good girl,” he stood up. “Your Daddies will be so happy you know how to behave when they’re gone.”

As long as someone was happy.

Chapter Text

You could not shake the feeling of sadness that clung to you. Not when Yamada or Aizawa put on the shows they knew you liked. Not when Aizawa sat on the floor with you and played with your little play sets with the little people. Anytime you thought you heard a car approach, you’d perk up, certain it would be them.

But you were always disappointed.

Each night, Aizawa put you to bed. He decided you’d be safe sleeping in your crib. The first night, you thought you were going to throw a tantrum, the way you had when you were with Denki. You had not counted on the fact that Aizawa was far less patient.

The very moment you had screamed, he had come in, silent and stoic. He had grabbed one of your pacifiers and forced it into your mouth. It was clasped behind your head before you could even realize what was happening.

“Hush,” Aizawa said, peeling your fingers off the side of the crib and laying you back down. You started to thrash, and he reached down and pinned your arms. You looked up at him with big, teary eyes.
“Oh, I can see why they have such a hard time telling you no. But I am not like your daddies. Who do you think it was that taught them?” your eyes went wide. “And I may have taught them everything they know, but I certainly didn’t teach them everything I know.”

You stared at him, scared to move. He left your arms pinned for a moment before slowly moving back. He grabbed your favorite blanket and tucked you in. Even though he looked so stoic, he moved with intention, and his touch was gentle. His knuckles rubbed your cheek.

“You miss them. I know that. We all know that. We all understand. But you have to understand that I will not tolerate that kind of behavior. You can’t make us unhappy because you’re unhappy.” he kissed your forehead before standing up straight.
“Try and sleep.”

Even though he placed you in your crib each night, you did not stay there. The first night, when you had woken and found yourself crying, you sat up and swiped at your eyes. The pacifier gag was still in your mouth, and so you could not cry out. But you had been sleeping in Izuku and Katsuki’s room, and Aizawa and Yamada were in their bed.

“Baby girl,” Yamada pushed the covers back. He walked slowly and carefully, making sure you knew every move he intended to make. You wanted to give him a dirty look, you wanted to shrink away. Instead, you held out your arms. He reached for you and lifted you up.
“You a little lonely?” he swayed in the calm of the night. It was strange to have the house so still. Sometimes someone had a late shift, or was up puttering around because they had some chores to do, or could not sleep.

The quiet made you feel so lonely. You whimpered and tried to hide your face in Yamada’s shoulder. Wordlessly, he took you back to the big bed he was in with his husband. Aizawa rolled over and cracked one eye open. He yawned, but remained quiet as he draped the blankets around you and then wrapped an arm around your waist. He pulled you in tight, but he did not take out the gag.

You found that you did not have an appetite, picking at your meals. The first few, Yamada and Aizawa said nothing. But after the second day when you’d barely had a bite, Yamada sat down by your high chair. He picked up your little plastic fork, and constructed a bite of supper.

“Say ‘ahh’!” he offered you the bite. You looked at it and him. You were all set to refuse hen you spotted Aizawa, standing behind his husband, arms crossed over his chest, staring at you. Slowly, you opened your mouth.
“Is it yummy?” Yamada enthused. You chewed and swallowed, feeling it go down like a cannon ball. You managed a few bites before begging off. Aizawa pressed his lips together, but you got the feeling he wasn’t upset.

“Take the baby to the living room.” he said, heading to the fridge. You were slightly terrified when Yamada took you to the living room. But Aizawa appeared with a bottle, though it wasn’t full of juice or milk. You cowered away when he reached for you. It didn’t shock you when he was undeterred.

You thought he was going to make you lay in his arms, but he let you sit in his lap and handed you the bottle. You took a few cautious sips, surprised when it was a thin smoothie. You relaxed and drank while Aizawa talked to Yamada, rubbing your back. You couldn’t hide your blush when you began hiccupping and Aizawa held you close and patted your back.

It was easier to act out with your daddies, you thought. Every night he put a pacifier in your mouth, warning you that he would use the straps. You didn’t dare to test that theory. But whenever he and Yamada were ready to go to bed, one of them would lift you out of the crib.

It was not the same as sleeping with one of the guys you thought. But there was nothing wrong with it. You didn’t mind sleeping there, and if you were honest with yourself,it did help. A little.

It really surprised you that other than blow jobs, neither of them seemed particularly interested in you sexually. They seemed more thrilled when they got to bottle feed you, which was a daily occurrence.

What they really enjoyed, you found, was making you feel so, so small.

“You really shouldn’t be playing with these alone.” Yamada frowned at your little playsets. “You could choke. I have a better idea.” he went to your play room and came back with a basket of stuffed animals and soft dolls.
“Here, lovey, these are much safer.”

“Please, I need to go pee.” you begged quietly. Aizawa shook his head.

“No,”

“But my Daddies–.”

“Aren’t here.” he finished. “And you’re meant to do what we tell you to do. And I think you’re just fine in the diaper.” You tried to sneak away, but Aizawa had grabbed you and situated you between his spread knees.

“Please!”

“You’re getting upset for nothing.” he said calmly. When you couldn’t hold it anymore, when you pissed, tears streaming down your cheeks, he had smirked, seemingly thrilled. You almost collapsed.

Yamada loved giving you a pacifier. He had gone out and bought ones that weren’t dick shaped, saying that wasn’t very good for your jaw. You wondered what Denki would think about that when he returned, but knew better than to push it.

Instead, he gave you pacifiers with cartoon characters on the shield, or beads, or gems. Anything to make them flashy and obvious. You wondered why your play sets were dangerous, but the gems weren’t?

You were sitting in the living room, moving some of your stuffed animals listlessly. You heard footsteps approaching and perked up, hardly daring to believe it. Aizawa was watching you as you slowly stood up.

The door was barely open when you were racing towards it, arms held out. Denki caught you up in an enormous hug, crushing you to his chest.

“Daddy, Daddy, Daddy.” you chanted behind the pacifier. He closed the door with one arm, leaning against it as he held you. He was silent, which was unusual for him. Even when he looked up at your baby sitters, he still didn’t put you down.

“Welcome home.” Aizawa said smoothly.

“I was cut loose, they didn’t need me anymore. I just couldn’t wait one more day for my baby.” he kissed your forehead. “How was she?”

“Once she knew who made the rules, she was fine.” Aizawa shrugged. Yamada was gathering their bags. Had they known? Did they not tell you? You didn’t care, it didn’t matter.
“She’s spoiled.”

“I know,” Denki sighed. “But maybe now she’ll appreciate us just a little more. You know, since she spent time with you.”

There was something in the way he said it that made you feel strange. You couldn’t pin point it, and didn’t care to. All you cared about was that Daddy was home.

Chapter Text

You would not let Denki out of your sight. You toddled after him when he went to take his shower, sitting on the floor of the bathroom. Steam surrounded you, heavily scented with his body wash. When Denki came out, he wrapped a towel around his waist and carried you to his room.

“Were you a good girl?” he asked. You nodded and looked down at your hands pressed to your thighs. Denki dressed quickly, grabbing a diaper to get you changed. He climbed into bed, smiling when you practically attached yourself to his side, face pressed deep into his neck.
“Did you miss me?”

“All the time,” you said honestly. He kissed your head, keeping you against him. One hand began a steady rhythm of patting, and he wasn’t surprised when you fell asleep. You were so precious, he thought, completely besotted. Your lips were parted, your cheek smushed against his skin. Your fingers were holding tightly to his shirt.

Denki was able to maneuver and hold his phone up, taking a picture of the two of you. He smiled broadly in it. He sent it to the group chat and settled to cuddle you. Denki had missed you, too. There had not been one night that he had not ached to have you in his arms, having you snuggled against him. His phone buzzed, and with one hand, he thumbed through the chat.

Blasty: Seems like some time with Aizawa settled her ass.
Deku: That’s not nice, Kacchan.
Rock Hard: I miss her.
My Taped Love: I miss her, too.
Deku: I miss her, three.
Blasty: That is not a good joke.
Blasty: But I miss the baby, yeah. Don’t tell her I said that.
Bolt: Aww, Kats! You scared she’s gonna know you’re soft for her?
My Taped Loved: I think she already knows…
Deku: She does.
Rock Hard: We’re all soft for her. That’s why we had Aizawa come.
Deku: She’s probably a sadder but wiser baby now.

Denki set aside his phone and settled down. He wasn’t tired, but it was your ordinary naptime and he wasn’t going to disturb you. Aizawa had mentioned that you had frequent night wake ups. And even though you hadn’t had a tantrum since that night in the crib, he said that you still seemed a little cranky.

Not acting out, he said. He could tell it was because you missed him. You were the first sub he had trained this way, and you wouldn’t be the last. Aizawa was right, Denki
thought as he felt the steady rhythm of you breathing. You were spoiled. How could it be helped, though?

Denki had watched for a few months before this started. He had seen the dark marks that were apparent under your eyes. He had seen the way that you poured over the wanted ads, hoping to find something you were suitable for.

“You know we can cover your portion of the bills.” Izuku said gently. “It’s really not worth stressing yourself out over.”

“I can’t rely on you all to cover all my bills.” you snorted.

“But why?” Eijiro had been truly confused.

“Because I’m not a kid and none of you are my daddy.” you snorted. Hanta had smirked at you.

“Depends on what kind of daddy you mean.” he drawled.

“You’re gross.” you threw a couch pillow at him playfully. “I love the way things are. I’m happy living with you! But what if someday you don’t all want to live together? I mean, there are some couples here. Or what if Eiji meets someone and falls in love and wants to move in with them?”

“We would always make sure you were taken care of.” Denki said. “Whatever else happened, we would never just abandon you.”

“But I’m not your responsibility.” you told them. “That’s the thing. I’m an adult and I have to do adult things even when I don’t like to.”

When Denki had gone to bed that night, he tossed and turned. Eventually, Hanta had woken and turned to look at him.

“What’s on your mind, Sparky?”

“You know I hate that nickname.” he frowned.

“I do.” Hanta agreed. “But now that I have your attention, what’s bothering you?”

“Something our roomie said.” he rolled to look at Hanta. He let his fingers trace down his face then sweep up to run over his eyebrows. Hanta hummed, leaning into the touch.
“She works hard.”

“She does.” he agreed. “We've always admired that about her.”

“But she doesn’t have to work so hard. Aren’t you worried she could make herself sick? She keeps saying that she has to get a better job. She keeps trying to do more.”

“She’s independent, babe.” Hanta shrugged.

“What if she didn’t have to be?”

“I can’t think of a way to make that happen.” Hanta said slowly. “That’s part of her personality. She’s not a child.”

“But what if she was?”

“Denks, I love you, but it’s late and you’re confusing me.” he kissed his cheek.

“Have you heard of age regression?” Denki asked. Hanta’s brow furrowed, and he shook his head. Denki grabbed his phone and typed in a few things, handing it over. His lover scanned the words, eyebrows rising as he did so.

“Where the hell did you hear about this?”

“I fell down a kink rabbit hole one night when I couldn’t sleep.” he confessed.

“We can’t force her into anything, and I don’t see her going for that do you?” Denki shrugged.

“Maybe not, but we are heroes, aren’t we? We have to do what’s best for people even if they push back. We have to save people, and even some of them who may not necessarily want to be saved.”

“I don’t know that forcing her to be a child would be saving her.”

“Yes it would!” Denki sat up, excited. “Think about it. No more stress for her. No more working those dead end jobs. No more of her scrimping and saving every penny. Hell, Izuku already lies to her about how much her share of groceries is so that she can have a little more money.” he beamed.
“It’s perfect.”

“She’ll hate it.”

“Probably at first,” he shrugged. “We’d have to talk her into it. But I’m willing to do that. I’m willing to do whatever it takes for her. Besides,” he laid back down, feeling content with his plan. Hanta sighed, not speaking about it again. Likely he’d forget by morning, he thought.

Instead, there was a link sent to the group chat that morning. Along with Denki’s excited text. Izuku had said he liked the prospect, but didn’t see how it would work. Eijiro was, shockingly on board. Katsuki said nothing.

“What if I don’t want a baby?” Katsuki asked one evening when they were home and you had picked up a late shift.

“Then we wouldn’t do anything.” Izuku said. “If Hanta, Denki, and Eijiro want this for her, and they find out she wants it, then we can’t stop them. But we could consider moving out.”

“What don’t you like about it?” Eijiro asked curiously. Katsuki squirmed and shrugged. “Because she won’t be a baby. All the things you enjoy doing with her now we’ll still do those things. She just won’t be so tired and stressed, and she won’t have to worry.”

“We can try it.” he mumbled. It wasn’t long after that you came in, still in uniform. You gave them all a smile, hanging up your bag.

“Hey babe,” Eijiro grinned. “Want a hot grilled cheese?”

“I would love that, thank you!” you smiled at him. He got up and hurried to the kitchen. You plopped on the sofa next to Katsuki. He let one arm sling around your shoulders. It wasn’t ten minutes before you were asleep, head on his shoulder. He looked down at you. It had been your third double shift that week alone.

“Aww, poor thing.” Eijiro sighed when he walked in with your plate. “I’ll take her to my room.”

“We should do it.” Katsuki blurted. Everyone looked at him. “She needs… She’s too…” he trailed off clearly frustrated. Words so rarely failed him. Eijiro nodded in agreement and came to lift you up, taking you to his room to lay you in his bed.

The plan had come together slowly. Items bought and hidden here and there. Articles read and discussed. Forums combed over. Most people did not have to be forced into it, they learned. There were a few places dark places with few postings that said they had forced it. And that their little ones were happier than ever.

Guilt pricked at Denki, just a little, but he brushed it off. Sometimes you had to put people through something they thought was painful to get them their best lives. Like setting a broken bone.

Before they could put too much into play the accident had happened. After that, Izuku quietly approached all of them and recommended putting something in your evening juice. A simple little diuretic, it wouldn’t hurt you. It would leave your bed wet, and they had all read that bed wetting was an excellent way to put someone down in their headspace.

And now here you were, Denki thought gleefully. Snuggled in his arms, in pajamas and a diaper, cuddled against him like you couldn’t tolerate the thought of him not being in arm’s reach. He sighed happily. You squirmed making a fussy sound, and he went back to patting your bottom, feeling you settle.

“Aizawa is right.” he said to you quietly. “You are a spoiled little thing. But I think I like you best this way. Our baby girl, dicked stupid and not wanting anything but us.” you made a sleepy noise and stirred a bit.

“Daddy?”

“Hush, baby, sleep a little longer and then I’ll make us some supper.” he promised. “I’m not leaving you.”

Chapter Text

Katsuki felt you stirring next to him. He opened his eyes to look at you with sleep blurred eyes. You were tucked into his arms, and had fallen asleep so easily. You refused to sleep in a crib since they had come home, but all of them had to admit you were very well behaved.

There had been little fussing, not a peep out of you during diaper changes, and a willingness to sit in the high chair and eat from the little plastic plates given to you. You had been much more clingy, though. You wanted to be snuggled, held, carried. You wouldn’t sleep in the crib, insisting you had to sleep with them.

And while Aizawa was right, you were terribly spoiled, Katsuki couldn’t help but think maybe that wasn’t the worst thing for you. Maybe you just needed an attitude adjustment. He wasn’t sorry that it had come from someone as strict and exacting as Aizawa. Hell, he’d taught all of them, and they knew not to push his buttons.

You had to learn the hard way.

You whimpered in your sleep, shifting so you were laying onto of Katsuki, one of his legs between yours. Sometimes you slept this way and he didn’t care. He yawned and settled back down, patting your back idly, waiting for you to doze back off.

You kept making sleepy little sounds, squirming against him. Were you uncomfortable? What was wrong? Katsuki frowned as his hand trailed down to your bottom, patting to see if you were wet. But your diaper was dry. Maybe you had to pee, he reasoned. And if he was awake, he’d just change you when you were done. If he was clever enough, he could do it without waking you up. And then back in bed with you and Deku. Perfect.

But the diaper didn’t get warm, and you didn’t go still. If anything, your movements increased. Katsuki was confused, his fingers slipping into the leg hole of your diaper, trying to adjust. Maybe you were uncomfortable, that had to be it. But everything felt fine. He glanced at your face, confused at the color rising in your cheeks.

And then he felt the dampness.

“Oooh, honey bunny. You are having a very good dream, huh?” he chuckled in your ear. You gave the tiniest, cutest little squeak he’d ever heard. He adjusted you so you were chest to chest, one of his feet flat on the bed. His thigh was snug against you, and he began to bounce slightly.
“Is it me? Is laying near me giving you such good dreams? Do you think about me in your sleep? I think about you all the time. You and Deku.” his hands moved to restlessly rub up and down your back.

Katsuki couldn’t deny the way his dick was stirring. But it was late, and he didn’t feel like undressing you. And that might wake up the nerd, and he didn’t want to deal with that, either. Best to just get you off and snuggled again. He bounced his leg a little faster.

He did like having these moments with you, he thought. The idea of kids didn’t appeal to him at all. But you weren’t a child, were you? No, you were something else. Your hands came to press against his chest, your hips rolling with a predictable rhythm. You were gasping, your cheeks hot.

“Almost there, baby.” he whispered. “Go on, cum for me. You’ll feel so much better.” he praised you quietly as your pelvis lost the rhythm, going harder and faster. He could feel the way your body tensed up, he could feel the way that you were so close.
“Baby, baby, cum.” he whispered again.

You let out a punched out sound, your body going tight, and then relaxing against him. Your breathing was still fast.” he left you laying on top of him, rubbing your back and kissing your temple, telling you in a soft voice what a good job you had done.

When you were still and calm again, your whole body limp, he rolled over. You were tucked between him and Izuku. Izuku automatically reached out. Always cuddly, that one, Katsuki thought with a scoff.

“What’re you doin’ up?” Izuku mumbled sleepily, cracking one eye to look at his husband. Katsuki didn’t answer for a moment, continuing to settled the blankets around the two of you.

“Baby was up.” he said gruffly.

“Does she need something?” he seemed more awake now, looking down at you.

“I settled her, pipe down.” he snorted. He settled himself in next to you, arms going over you to reach for Izuku. The other man hummed and kissed your head, smiling at his husband before drifting back off to sleep himself.

***

“I bet you are tired.” Katsuki teased as he picked you up in the morning. You grumbled, trying to burrow into him.

“Sorry, Deku and I are working today. You can go lay down with Soy Sauce Face if you want.” he offered. You nodded, clinging to his shirt. He carried you to another bedroom, and you faintly heard the rustling and rearranging before you were handed to someone.

“Come here, baby. You still sleepy?” Hanta cooed. You grumbled again and turned to burrow into him, making yourself comfortable.
“Is something the matter?”

“She was restless while sleeping.” he wasn’t sure why he didn’t want to share that you had rubbed yourself off on him in your sleep. He felt like maybe it was a more private, more intimate event. It wasn’t a story to be shared with the others. It was a moment between the two of you. Katsuki reached out and smoothed your hair down.
“She needs some more sleep.”

“Anything she wants.” Hanta settled back in bed, turning on his television and settling back. Maybe he would have gotten up, but if he had a lapful of sleepy, cranky baby, he wasn’t going to go anywhere.

“Love you, babe.” Katsuki whispered in your ear.

“Love you Daddy.” you muttered back.

Katsuki kept a soft smile hidden to himself the whole day.

Chapter Text

You laid across Hanta’s lap, stripped down to a diaper. He rubbed your back idly as he watched television. You sighed, closing your eyes, feeling the warmth of his hand on your skin. His hand went to the back of your neck, rubbing at that place where you seemed to hold all your tension.

“You comfy, pretty girl?” he cooed. You gave a faint nod, turning your head so you were looking at him instead of the television. “You sure look comfy.” he patted the back of your diaper, smirking when the faint blush rose on your cheeks.
“Aren’t you much happier wearing a diaper? Just being our dumb little baby?”

“Don’t tease, Han.” Eijiro scolded gently as he came in. He dropped down onto the couch adjusting you so your head was in his lap.
“There you go, my love.” he began to rub your scalp and play with your hair. The feeling of the two of them was heavenly. You could have fallen into a trance.

It wasn’t long before Hanta’s hand traveled down to your bottom. You made a face, lifting your head. Hanta gave you a lecherous grin and gave your diaper a little squeeze. You ignored the way your face warmed up.

“Still dry? We can fix that.”

“No,” you protested, trying to wriggle away from him and sit with Eijiro. But the red head put his hand between your shoulder blades, pinning you down.

“Yes,” Eiji said in that gentle voice they used when they were trying to coax you into something you didn’t like.
“You know that you’re always in a better mood if we get you to cum.”

“I’m not in a bad mood!”

“You sure sound like it.” Hanta hummed. Your jaw dropped open. You were only protesting because they were pushing! Why was it a bad mood if you didn’t want to do something? Why was it a bad mood if you stood up for yourself?

“Need something in your mouth?” Eijiro asked. Before you could answer, he was shifting and scooting on the couch, pulling down his sweatpants. He tucked the waistband of his boxers behind his balls. His cock was swelling, the erection making it stand tall and proud.

Well, you thought, it was better than one of those stupid pacifiers. And you did like giving blow jobs, and Eijiro was giving you such a kind look your heart skipped a beat. You swallowed and bent your head, taking the tip of his between your lips.

“That’s it,” Hanta encouraged. “What a good girl you are.” the praise made your brain feel fuzzy, along with the way that he was angling you so your backside was in the air. He rubbed at your diapered bottom for a few minutes, apparently content to watch you give a blowie.

Well, you thought. If you had an audience, you should put on a show. You took a breath and took Eijiro down as deep as you could without warning. He moaned, long and loud and low. A shudder went down your spine. Hanta gave a choked off grunt.

“Careful baby.” Eijiro sounded a little breathless. “Don’t hurt yourself.” you pulled back and went down again, taking him a little deeper. You weren’t able to fully deep throat, but that wasn’t a problem. Not really. Everyone was enjoying themselves.

Hanta’s hand slipped between your thighs. He rubbed at your cunt, which certainly was beginning to drip with arousal, over your diaper. For all they were so thick, you thought ruefully, you could feel his hand. You could feel the way that he was varying speed and pressure. You knew that he was watching your reactions seeing the best way that he could make you respond.

You bobbed your head on Eijiro’s cock, feeling the heavy pressure of his fingers on your head. You took a deep breath and sank down, dragging out the feeling of your lips on his hot skin. Eijiro gasped, his hips rising off the couch.

“Easy, Ei.” Hanta said softly. “Don’t hurt the baby.”

“Never,” he managed breathlessly. “Never never hurt the baby.”

Hanta's fingers were rubbing the plush lining of your diaper against your clit. You whined, the vibrations of your lips making Eijiro’s eyes roll back. Hanta chuckled, and his other hand reached around your belly, pressing down.

“Piss for me, baby girl.” he demanded. You wanted to argue, but you did have a full mouth. Eijiro was keeping your head down, and so all you could do was release your bladder, feeling your diaper swelling. Hanta let out a little moan. Your hips were rolling, wet diaper swaying.
“See? I knew you liked it.”

“Be nice.” Eijiro wheezed out. “She is being such a good girl.”

“Always a good girl. After all, we did make her that way, didn’t we? And a nice orgasm and a dry diaper will make her an even better little girl.”

He pressed his hand to your cunt again, feeling you ride against his fingers. You whimpered and moaned around Eijiro’s cock, going faster. You were so close, feeling your nipples going hard, your hips losing rhythm as you humped wildly.

“Go on, baby.” Hanta encouraged. “Cum for me. Almost there, I can feel that you’re right there. I can see it.”

“Cum,” Eijiro whispered. And before you could figure out if it was an encouragement or a warning, your mouth was full of his sticky spend. You swallowed, pulling your head back to suckle on his oversensitive tip.
“Baby girl,” he moaned.

And that was all it took for you to come, back arching painfully, Hanta leaving his hand between your thighs. He moved differently, slower, careful not to hurt you. He worked you through the trembling of your orgasm. Still shaking, you sank down, head on Eijiro’s thigh.

“There it is.” Hanta sounded satisfied. He reached for the tapes of your diaper, undoing them and rolling the soiled item to throw away. Your eyes were unfocused, and you barely noticed him. He reached for the wipe warmer, grabbing a few of them to wipe you clean, handing a few others to Eijiro.

“Daddy,” you whined. You were hushed by the redhead as he wiped his cock clean and then swiped at your face. You ached to be cuddled after a sexual event, which they all knew.

“Come on, clingy.” Eijiro teased as he hauled you up until you were chest to chest. “Daddy’s getting you a fresh diaper.” sure enough Hanta was rummaging through the little basket. He grabbed a diaper, and Eijiro held you up until it was settled under you, holding the front until Hanta got it taped.

“Such a good girl.” Hanta sighed happily, kissing the side of your head. “Have a cuddle with Daddy before lunch.”

“A present?” you perked up. Denki did give you such wonderful gifts, after all. He nodded, reaching for you as you sat on the floor in your playroom. You gave him your hands, letting him haul you to your feet. You giggled as he made fake straining noises, like it was a major feat to lift you up.

“Come on, love, Izuku is in the living room, he wants to know how you like it.” you trotted to the living room, eager and curious. You looked at the large stuffed teddy bear that was sitting in the middle of the living room. He was huge, sitting there with his head tilted to the side, an embroidered on smile.

“Ta da!” Izuku wiggled his hands, laughing when you smiled.

“What’s his name?” you asked.

“Whatever you want.” Denki shrugged. You walked closer to examine him. You startled when you realized what was between the bears fuzzy legs.

“A strap on?” you stepped away.

“We thought you might like a little friend to have around in case we weren’t available and you needed something.” Izuku explained. The bright pink dildo stood tall and proud, held on by a black leather harness.

It was a little grotesque to see it like that, attached to such an adorable, huge bear. But as soon as they said it, you thought you could see it. Funny to assume that they’d ever not be available if you ever expressed a need, though. Any of them would leap at the chance to be with you.

“Wanna give it a try?” Denki waggled his eyebrows. You felt your face going hot. You should say no. You should scowl and run off. But you did wonder how the dildo felt, and you did want to see what kind of angles you could get from it.

You nodded, slowly, staring at the bear. You missed the lecherous grin the two men exchanged.

“Come here to Daddy.” Izuku cooed, flexing his fingers at you. You walked over slowly, aware of the way your heart was pounding and how your knees were trembling. Luckily for you, Izuku worked quickly and efficiently, undressing you with a clinical air.

Your little cotton dress was put on the couch next to him. He undid the tapes on your diaper, then drew you to him, his hands cupping your bare cheeks. You made a needy sound as he pulled your naked body to his chest. He laughed, the rumbling sound traveling through you like electricity.

“You can pretend all you want.” he said in your ear. “But we all know how much you need this, how much you want this. You’re the perfect little slut, aren’t you, baby girl?”

“I am not a slut!” you protested. Denki laughed, kneeling behind you, kissing your shoulders, his hands wrapping around your waist.

“Even if you are, it’s because that’s what’s best for us.” he said. “We love it. Don’t fret. Now, I think your bear is lonely. If you don’t go and see him, I’m going to think that you don’t like it when I bring you gifts.” he warned.

You broke away from the two of them, walking to the bear. You gave him a gentle push, watching him fall on his back. You took a breath and straddled him, surprised at how wet you were getting just at the idea.

Your hand shook as you reached underneath you, making sure that the dildo was lined up. Slowly, carefully you sank down onto it. It wasn’t as nice as being fucked by one of them, you thought. But there was something to be said for the way that you could roll your hips, squirm and adjust yourself so that that deep, eager part of you was touched.

“Daddy,” you moaned, your head falling back and you began to grind.

“Is your new friend making you feel good, honey?” Denki asked. You nodded, bouncing your pelvis. You leaned down, your hands gripping the fuzzy shoulders that had no resistance. You whined as you humped, feeling all the best places inside of you being stimulated.

“You get our baby the best things.” Izuku sounded so admiring, so thankful, it twisted something inside of you.

“She deserves them.” there was a certain hitch in Denki’s voice that made you look over. You saw him there on the couch, his legs spread wide. Izuku’s hand was down the waistband of his sweatpants, and you could tell that he was being jacked off.

“You can’t cum until she does.” Izuku warned. “So you better help her.”

“You like it, baby girl? I sure do like watching you play. Watching your tits bounce. You’re such a dirty girl. When we got you, I was afraid you wouldn’t like us at all. But now look at you! You’re happy and free, and you’re exactly what we needed you to be.”

“Daddy! Daddy!” you cried, not sure who you were crying out for. Izuku laughed, a dark sound that made goosebumps rise on your flesh. A ball of tension was building in the pit of your stomach as you adjusted your angle once more.

“Oooh, look how close she is.” Izuku hummed. “She’s got that look in her eye. Gonna cum for us, baby girl? We won’t know how good the toy is unless you do.”

“Don’t want bear to think that he wasn’t good enough, do you?” Denki’s eyes were glistening, and you wondered if he was just as desperate as you were. You nodded faintly and rolled your hips one more time.

You moaned, long and low as you arched your back, cumming hard around the silicone inside of you. You collapsed onto your bear, watching with hazy eyes as Denki pressed his hips deep into the couch. You listened to him as he came.

“Made a mess in your pants.” Izuku clicked his tongue. “Maybe we need to get you padded up the same way we do the baby.” he teased. Denki turned pink and shook his head, pulling away from his lover.

“I’m gonna get her dressed and cleaned up.” he said instead. He dropped his pants and sticky boxers, limp cock swaying between his thighs as he headed over to you.
“Hi baby, girl.”

“Thank you for my present, Daddy.” you managed through your hazy of pleasure. He smiled and kissed both your cheeks, snatching the diaper Izuku threw out of the air. He looked at you full of adoration and worship as he slipped it under your pelvis.

“You really do deserve it, baby. You’re such a good girl. You’re so perfect.”

Chapter Text

It was a perfectly normal day. As normal as your days were, anyway, you thought. And you were beginning to believe that maybe this kind of normal wasn’t such a bad thing. Not if you were mostly happy, and not if the guys were mostly happy. You sat in the living room, reading a book. Your legs waved in the air, and you might have been any normal kind of person. There was only the puffiness of your backside underneath your dress that would have given anyone even a hint that there was something a little different about you.

You were lost in your own world when Izuku stood up and stretched. He gave you a smile and made grabby hands. You stood up and trotted over, fully expecting to get diaper checked and then carried to the kitchen for lunch.

Izuku and Katsuki hated it when you ate in the living room. They said that good mannered babies ate in high chairs. Izuku had even lectured the other three on you choking if you weren’t in the chair.

You hadn’t pissed. It was still a production when you went to pee in the diaper. There was still a lot of turmoil, and so many times you begged to be allowed to hug someone while you wet yourself. But as soon as you took a step, you gasped feeling your face go warm. Your diaper was soggy. Izuku gave you a concerned look and walked over.

“What’s wrong, baby girl?”

“I wet my diaper!”

“Well, that’s why you’re wearing it.” he looked baffled, even more concerned when you began to struggle in his arms, trying to shove him away. Your heart was pounding, and you weren’t sure that you were going to be able to vocalize anything.
“Sweetie, calm down, no one is upset.”

“You don’t get it!” you choked out. “I didn’t want to.”

“Have you ever wanted to?” he snorted. “Face it, love, you’ve been fighting us the whole time!” you shook your head. You shoved at him again, sobbing. You were dissolved into a puddle of despair. Izuku frowned, realizing there actually did seem to be something wrong, and you didn’t seem able to tell him.
“Okay, okay.’

“The hell is going on?” Katsuki grumbled as he came in from the office. Izuku shrugged helplessly, walking around the room as he bounced you and rubbed your back. You continued to cry, a steady wail and was more heartbreaking than annoying.
“Give her here… Why are you leaving her in wet pants?”

“That’s what started this.”

“She hasn’t had a fit like this over a change in awhile.” he laid you down on the change mat. When he flipped up your dress, you howled. He scowled and pressed your hips down where you were trying to arch up.
“Oi! That’s enough! You’re gonna get a rash, and you’re always a pain in the ass when you have a rash.”

“Stop,” you managed through hiccuping breaths. “Please, I don’t want to do this anymore. Please no more. No more.”

“She was just fine.” Izuku said helplessly. Katsuki didn’t respond, instead pinning down your hips with one strong arm. He moved quickly, untaping your soaked diaper and putting it to the side. He gripped your ankles and lifted your bottom up.

“Katsuki, no. I’m saying no. Can’t you hear me?” you pleaded. He didn’t say anything, only taped you up and moved his arm. You scrambled up, almost tripping over yourself. You were panting, hurrying towards your playroom. Izuku caught you around the waist, holding you to his chest. Your legs churned in the air, clawed at his chest.

“What is wrong?” he asked, even though he clearly didn’t seem to expect a response. “Come on, you’re dry now. Please, settle.”

“It’s not like she’s missed a meal or a nap.” Katsuki stared. Izuku dropped into a recliner, kicking back the foot rest. You continued to wail. He pressed you to his chest, coaxing your face into his neck, letting you hide there.
“Is she sick?”

“No, no fever.” he kissed your forehead, letting his lips linger. “She hasn’t complained, she’s ate breakfast. She’s been fine. I really do not understand.” you continued your sorrowful cries. Words were beyond you. There was only the aching realization and what that meant for your world.
“No rash or anything weird?”

“Nothing,” Katsuki shook his head. “And Shitty Hair said that she slept really well last night. He had her in his bed.”

Izuku reached an arm out, snagging your blanket from a laundry hamper. He wrapped you in it, relaxing a bit when you grabbed the familiar fabric, going limp in his arms. Your hot tears still trickled down his skin, but it was better, at least.

A pacifier, the same kind that Mic had given you, was coaxed towards your mouth.You didn’t hesitate, grateful for the comfort that it gave you. He pushed his hand up your dress, rubbing the bare skin on your back with the tips of his fingers.

“Maybe she’s just tired. Babies fuss, Kacchan.” he mused. He adjusted your blanket so it was covering your head, giving you some time in darkness. You were there with him, and he was trying to shield you from the rest of the world.

If only he understood that the problem was you. And you had no way to even try and solve it. When you were limp and you seemed all cried out, Izuku stood up to carry you to the kitchen. Even though he was the biggest advocate for you to sit in the high chair, he let you sit in his lap, feeding you off his plate.

You didn’t notice that for all their light conversation, Katsuki and Izuku were giving each other worried looks. You didn’t fight when Katsuki announced that you needed a nap. You were compliant but limp in his arms, and didn’t cheer up when he laid you in his bed.

“Want me to stay with you?” you shrugged. Katsuki frowned and crawled in next to you. You leaned into him as he pulled you in close.

You’d figure a way out of this.

Chapter Text

You barely ate. You didn’t fuss about being put in your seat, but you didn’t seem happy there, either. You seemed to take it as a force of nature that you’d never be able to fight. You picked at your plates, and even though you were well behaved and didn’t throw tantrums, it still made your daddies uncomfortable.

“What’s wrong?” Sero asked, smoothing your hair back from your face. You could only shrug. Even if you thought you had the words to tell them, you couldn’t believe that they would understand. They never seemed like they would, even when you had told them before that you wanted to stop.

You had to show them that you didn’t need these things. You had to figure out another way to explain things to them. Even, you thought, if it made them angry at you. Part of you cringed at the idea of things being different, going back to the way that they had been. After all, you thought, there was a comfort here, and you were happy to be with them. Maybe they wouldn’t want you anymore if you were different.

But you couldn’t live like this, you thought. Not anymore.

Eijiro did his best to try and coax you out of whatever sulk it was you were in. He sat you in his lap, he played with your hair. Izuku brought home toys for you, and brand new books that he hoped would tempt you. You smiled your thanks, but even when you opened the pages, you found yourself zoning out, unable to concentrate.

At the very least, you hadn’t pissed yourself without thinking. Rather, you peeing was more of a production than it had been. You wouldn’t sit on anyone’s lap, you would secret yourself away somewhere, covering your face with your hands when you couldn’t hold it and had to fill your diaper.

They changed you the way they always had. Although they may have used to tickle you and tease you, now they were quiet. They were kind and gentle, and they didn’t try and pry your hands away from your face when you wouldn’t look at them. They normally hated that. It made you feel sick to realize that your plan was working.

It was going to be a loss to not have the parts of them that you had come to enjoy.

“Come on, baby girl.” Denki said one evening. “Close to bedtime, isn’t it? Do you want to sleep in the bed with me and Hanta?” they had been offering this in the past week that you had gone so quiet. You had refused politely each time, curling instead in your crib.

When you left here, when they told you to leave because you were no longer what they wanted, you would have to sleep alone. Might as well get used to it now. Maybe they’d let you keep the blanket, you thought. Why would they want something that was so thoroughly yours?

“No, thank you.” Denki looked crestfallen when you said no, but said no more about it. He grabbed a diaper. “I haven’t—,” you began.

“I just like making sure you’re in something fresh for bed, love.”

Denki laid you down on the change mat. He undid the tapes, reaching for a fresh diaper. As soon as he had gone to lift the diaper you’d been weaning, you felt your bladder give. You cried out, a sharp gasp. Urine fountained out of you, splashing onto Denki. He looked in shock, not quick enough to put the diaper over you.

“I’m sorry I’m sorry I’m sorry.” you babbled, a chant that you hoped would set things right. Denki said nothing in his urine spattered shirt. He leaned down to pick you up even though you were naked. He carried you quietly to the bathroom, standing you in the tub. He took off his clothes quickly, turning on the shower.

“Calm down, baby.” he said softly. “You’re fine. You’re fine.”

“I really did not mean–.”

“Shhh,” he was washing you off, then himself. You didn’t even have time to think about things as he wrapped you in a towel and took you back to the living room. Eijiro was looking at you in confusion.

“What’s wrong with the baby?”

“Nothing. Get her some pajamas?” he sat with you on the recliner, rocking a little bit. You were shocked to find that you were crying. It wasn’t long until Eijiro was back with a diaper and a nightie.

“Let me,” he held out his hands. You were still as he laid you on the floor, sprinkling you with powder. He dressed you tenderly and picked you up, leaving you on his lap. No one spoke for a few moments, Eijiro rubbing your back.
“What’s been going on?”

“Did something happen?” Izuku asked as he stepped in with a tray of warm drinks, and even a sippy cup. “Why is baby girl so upset?”

“I think,” Eijiro said softly. “I think she’s been feeling the weight of all the changes that have happened. And it is a lot, and she is just a baby.” he rose to sit on the sofa, grabbing the sippy and pressing it to your hands.

“You think too much.” Katsuki grunted, sprawling into his own seat. “That’s why your life was so hard. ‘Cause you thought too much. WHen will you understand that we can do all the thinking for you?” you didn’t respond, snuffling a bit.

“Poor thing,” Hanta hummed. “I think we can do something to make this even easier.” you glanced at him, not sure that you wanted to know what he meant. It was all too much right now. There was safety there with Eijiro, so you nestled in.

“It’s our turn to have her tonight.” Denki pouted when the warm drinks were done and you were lolling against Eijiro’s shoulder.

“But she’s so comfortable and happy with Eiji.” Izuku said. “And you know it’s been days since we’ve seen her like that.” Eijiro stood up and carried you to his room, passing by the crib without so much as a glance.

You were put in his bed, careful and gentle. He tucked you in, then carefully laid next to you. He laid on his side, his fingers tracing the contours of your face. You hummed and pressed into his touch, feeling some relief from the affection.

“I’m not sure what thoughts are tumbling around in that beautiful brain of yours.” he said gently. “But I want you to know that we’re all here to make things easier on you. That’s all any of us have ever wanted for you.” you reached out to grab his wrist, press your cheek into his palm.

“So now what?” Katsuki asked in the living room. Everyone was thoughtful for a few minutes until Izuku spoke.

“I think we need to do some things that we had agreed weren’t needed.” the others seemed to light up. Katsuki smirked as he pulled himself out of his chair.

“Perfect.”

Chapter Text

You were asleep when someone lifted you up. You stirred, humming. You were hushed, laid down on something that was firmer, harder. You fidgeted, brow knitting together. This was not the bed they normally changed you on, nor was it the change pad that they often laid down.

“No, keep still.” Izuku’s silky voice, in contrast to his roughened fingers skimming down your cheek. You blinked your eyes open, shocked when you looked around blurrily. What was this?
“This is much better for our backs.” Izuku hummed as he unstrapped your diaper. “Looks like you slept good, since my baby has such a soggy diaper.” he teased.

“Don’t!” you whined, putting your hands to your face. Izuku laughed and lifted your legs, sprinkling down some powder and taping you back in. He picked you up, and you realized that you were naked, other than your diaper.

“My baby!” Eijiro cheered as you came in. You thought you’d be sat in the high chair. Instead, you were in his lap, cuddled close to his chest. You squirmed, confused, uncertain. Eijiro made shushing sounds as he cradled you, one hand patting your bottom.

“Someone’s cranky.” Hanta noted brightly as he watched you in Eijiro’s arms. The red head rocked from side to side a little,

A bottle was handed over, and he popped it between your lips. You froze, staring at it. Yes you had some bottles. But never like this, and never for breakfast. You shook your head, trying to force it out of your mouth. Eijiro clicked his tongue and held you a little bit tighter.

“It’s perfectly warm, go ahead, baby.”

“I don’t want a bottle.” you managed, feeling something upsetting stirring inside of you. Eijiro ignored it, continuing to rock side to side. He pressed the bottle to your mouth, and when you refused, Hanta was at his side in a flash.

“Someone is a fuss budget this morning.” he noted. He reached over and squeezed your cheeks together. Your lips pouted out and you shook your head, trying to get him off you. Hanta was stronger and quicker though, and reached over and pinched your nose until your mouth opened.

Eijiro popped in the bottle. He was applying just enough pressure so that you had to drink, but you weren’t as likely to choke. Your captor looked down at you fondly, with the same besotted look that he often had when it came to you.

“There we go, isn’t that better? Were you just hungry, baby? Daddy knows.” you drank about half the bottle while the others talked at the table. None of them acknowledged the treatment you were getting, none of them were seemingly bothered, although you were.

Eijiro moved the bottle and you sputtered, coughing a bit. He wiped your face with a soft cloth and then sat you up. You were still naked, other than that diaper. You squirmed a bit, wanting to be let down. Eijiro made no move to do so, instead keeping your back to his chest, his legs rocking, his hand patting your thigh in time to the motions.

Honestly? It was making you feel sleepy and calm. You yawned, relaxing against him, enjoying when he kissed the top of your head. After a bit, they were collecting plates and talking about their plans for later.

“Come here” Katsuki took you from Eijiro, carried you to the couch. He grabbed a pair of socks and put them on your feet. You waited for him to get an outfit, or even a onesie. Instead, he set you on the floor with a fond pat on your ass.

“Be good, have a good day.” Izuku sang as he left the apartment. Everything seemed strange, too quiet. Katsuki was fiddling with someone in the corner, and you realized that the furniture had all been rearranged. What was going on.

“Come here, baby, pretty love, precious thing.” Katsuki looked fond as he snatched you. What was with everyone toting you around, you thought with a huff. He was moving you to a corner of the room where he had installed a playpen. The kind with the colorful gates that attached to the wall. It was just high enough that you couldn’t step over it, and the lock was a padlock on the outside.

“Wait what is this?I have a playroom–.”

“You’re too little to play there.” he shook his head. “No tiny pieces in here.” sure enough, there was a woven basket that held some of your plush toys a few books, and blankets. Katsuki handed you your favorite blanket, and your stuffed puppy.
“I’ll get my laptop and work in here.” he assured you.

“Daddy, no. Daddy, let me out.” you demanded.

“Hush,” he wanted. “I will be busy and I need to be able to concentrate, okay?”

It was not okay! You stomped your foot as he left. Sure enough, he was back in a second with everything he needed. He set up at the coffee table, not even looking at you. You grabbed the playpen and shook it. Katsuki didn’t glance your way.

“Daddy!” you shouted. “Daddy! I won’t stay here, I won’t!” hadn’t you just been thinking about the fact that you didn’t need this? How were you ever going to convince them of it if they left you in here?

“I am not going to fight you today.” he rose and sharply walked over with a pacifier. It wasn’t dick shaped, so you would to spit it back out. Katsuki held it to you, eyebrows raised in warning.
“This one straps on, too. I’d love to get you cute ones like Mic did when he was here. Do you like those more?” once again, he slipped into the candied tone that all of them used when talking to you right now.

You plopped down on your bottom, arms crossed over your naked chest. Katsuki was busy tapping at his keyboard, sighing every now and then, huffing here and there. You whined, annoyed that he was able to block you out so effectively.

It wasn’t long at all before you felt the pinch in the bottom of your belly that made you aware that you needed to piss. You stood up, and before you could even think about what to do, you were wetting yourself. You gasped and looked down at your diaper, swelling between your legs. You looked up at Katsuki, who had the most amused look on his face.

No words were exchanged as he lifted you up and carried you to the room he shared with Izuku.You realized that you had been laid on a change table earlier. Katsuki clipped a strap around your waist and then began to assemble items.

“Hell no,” you spat out the pacifier and reached for the buckle. His hands were on yours in a heartbeat, pinning your wrists up by your head.

“Don’t touch. If you can’t use your hands appropriately, you won’t like what happens.’ he warned.

“I don’t need to be strapped in. Can’t I be changed on the floor? Why are you doing this? Let me up, Kacchan, let me up!”

He didn’t speak as he undid your diaper and used a few warm wipes to get your bottom cleaned. A new diaper was slid on, even as you were sobbing, hands trying to claw off the strap. He picked you up and held you to his chest, swaying as he did so.

“There is no reason to be upset. Do you need me to help you calm down?” he didn’t wait for a response, carrying you to the bed. He laid you down and rummaged in a side drawer before coming up with a vibrating wand.

“I don’t–.” you began. He leaned down and kissed you sweetly, the wand forgotten for a minute. You made a crabby sound, but returned the kiss. Katsuki peppered kisses on your face and neck, including one on the tip of your nose. You crinkled your nose and giggled a little, happy to see him smile.

And then you felt the vibrating outside your diaper. Your back arched before you could think. Katsuki laughed softly, the vibrations from his lips making your cheek tinkle. He worked his way to kissing your neck, then moving his mouth to breathe wetly against your year.

He was so close to you, the heat coming off him in waves. You writhed on the bed, your nails digging into his skin. He blew out a breath, making you shudder. He tilted the wand carefully pinning you so you couldn’t launch off the bed.

It was unfair that they knew how to play your body so well. It was unfair that they knew what made you tick. He moved the wand a little bit, and you swore the vibrations were zeroed in on your clit. Having the texture of the diaper on you was even better. You moaned, unable to move, feeling your orgasm rushing towards you.

“Oh there you go, oh good girl, good girl.” Katsuki praised, his breath causing goosebumps to rise. You collapsed to the bed, breathless. He picked you up, carrying you back to the play pen and setting you down.
“An orgasm always makes you a good girl, doesn’t it?” you laid on the floor as he went back to the laptop. You felt the happiness chemicals washing over you. But all you could think was this was going a lot deeper than you thought it ever could.

Chapter Text

Katsuki had mentioned going to make some lunch for the two of you. You were alone in the playpen, although you could hear him in the kitchen. You sat up, rubbing your eyes. A hazy feeling had draped over you. You needed to focus, you thought. You needed to figure something out.

When Katsuki came back, he didn’t have a plate or a bowl. Instead, he was carrying another bottle, giving it a careful shake. Wordlessly, he lifted you up and carried you to the kitchen. On his plate was a pile of pasta, with the sauce that you loved the best. You inhaled, your mouth watering.

“Can you be a big girl and hold your own bottle?” Katsuki asked. You scowled, looking away.

“I don’t want a bottle.” you said through clenched teeth. “I want pasta.”

“No,” he said it so easily, like commenting on the weather. You craned your neck to stare at him. He wasn’t even looking at you. Instead, he was reaching for the small, soft cloth that he draped over one shoulder.
“Now do you wanna hold your bottle, or should Daddy do it for you?”

“I don’t need lunch then.” you crossed your arms. Katsuki shrugged and hand you cradled in one arm, tight to his chest. He had the bottle in your mouth before you could stop him. You tried to pull away, but he had you tightly.

“You are really not going to like if I have to manage you being fussy.” he warned. Tears stung your eyes as you drank from the bottle. This tasted different than this morning. There was something sort of bitter at the end, a note that made you want to take another taste to see if you actually tasted what you thought you had.

Katsuki was satisfied, watching you drink. He narrowed his eyes as you slowly reached up and held the bottle with one hand. Katsuki ate with one hand, still keeping you tight. You watched every bite of going into his mouth.

You ached for some of the pasta. You would have let him put you in the highchair, put that stupid bib around you. As long as it meant that you were going to get to eat. The bottle was emptied a bit later, and Katsuki sat you up. He leaned you against his shoulder, your chin against that small cloth. He began to rhythmically pat your back.

What the hell? Was he actually burping you? You squirmed, wanting to push away from him. He shushed you and kept patting. You coughed then, and to your shock, actually burped. Katsuki chuckled and you winced. He wiped your mouth with the rag, even though you hadn’t spit up or anything.

“There you go,” he felt satisfied then. “And we’ll get you into some dry pants and then you’ll be ready for a nap.”

“Daddy, I do not need to nap.” but your body was getting heavy. Your belly ached a little, and you knew you had to pee. What was happening, you wondered. Katsuki kept bouncing you a little as he carried you to the room.

“We’ll get you nice and cozy, and my baby can nap. And when you get up, I’ll be done working and we can play a little bit.” you struggled on the change table as he buckled you in and opened the diaper. As soon as he lifted your legs, you gave the smallest push. Urine trickled out of you, soaking the pad and Katsuki’s hand.

Neither of you spoke for a few minutes. You were unbuckled and swept off the change table, taken to a bathroom. Katsuki held you on his hip as he started the shower, pulling down the hose. You were wobbly on your feet as he stood you in and began to hose you off.

“I ain’t even gonna ask if that was intentional. I’m not giving you the chance to lie to me.” he said in a clipped tone. You were carried back to his room, diapered again, and you in the crib. You could barely stay awake now.

“Daddy,” you mumbled.

“And I’m not getting your blanket or puppy. You don’t deserve those right now.” he did cover you with another blanket.
“I’m not going to tell you to be quiet. I don’t need to.” and he was gone, leaving you there in the dim of the room that should have made you feel drowsy. You were afraid instead.

***

When you came awake again, Katsuki was hauling you to the living room. You thought he was going to put you back in your playpen. Instead, he stood you on quivering knees between his own. He let your wet diaper fall to the floor. You couldn’t meet his eye as he wiped you with some warmed wipes.

“Sit down,” he pointed to the floor, a little place where he had put some old blankets. You did so, confused. Katsuki didn’t say anything else, even though he had said that you were going to play. Instead, he handed you a sippy cup.

You drank solely, glad that you didn’t get bottle fed again. And this was just juice, not whatever he had put in your lunch bottle. You thought back to the pasta. Maybe, you thought hopefully, maybe if you could show him you didn’t need the baby thing. You could show him this had all gone too far.

The sippy cup was emptied, and Katsuki went and filled it again. He seemed engrossed in a book he was reading. Fair enough, you thought. But you swore you felt the weight of his eyes on you, and you hated that.

Once the cup was empty he rose and filled it again.

“I’m not thirsty.”

“I ain’t fuckin’ askin’.” he shrugged. You drank, feeling your bladder pinching. You whimpered and stood up. If you didn’t get to the bathroom, you were going to have an accident. Your face went hot.
“Where are you going?”

“I have to pee.”

“And?”

“I don’t have a diaper.” you swallowed hard.

“I see that,” he went back to his book. You bounced from foot to foot, trying to hold it. But of course, your body was so used to releasing whenever. You listened to the piss trickling down and splashing on the floor. Katsuki finally looked up, smirking.
“Had an accident?”

“I’m sorry!” you blurted. Katsuki rose slowly, stretching his arms over his head. He disappeared and came back with some cleaning supplies. He shoved you to the side and cleaned your mess, and even wiped your legs.
“Daddy?”

“You don’t like diapers? Fine. But big girls can hold it and don’t go pee pee all over the floor.” he moved the supplies to the side and went back to his book while you stared, mortified and naked.

Chapter Text

The sippy cup was filled again and again. You convinced yourself that you weren’t going to have another accident. You were going to hold your bladder. You were an adult, and part of you thought that it did make sense for Katsuki to want you to prove it. After all, it didn’t seem very convincing when you slept in a crib to just say you were grown.

You thought that you’d just take tiny fake sips from the cup. He couldn’t be mad at you for not guzzling. And for a time, that did seem to help. You got a reprieve, sitting there, naked on the floor. You shivered a little, curled into yourself.

Katsuki glanced at you and pulled out his phone, raising the temp of the room just a little bit. Your heart throbbed at the simple action. Even when he was mad at you, he was still looking out for you, you thought. He still wanted you to be comfortable. He still wanted you to be happy. All of this was because they only wanted you to be happy.

But you weren’t happy, you told yourself. You wanted to be allowed to live like you wanted to. And regular adults didn’t wear diapers and get put down for naps. You whimpered, chewing on your lower lip.

“You’re okay,” Katsuki came over to kneel down in front of you, putting his hand on your head. “Everything is fine. You’re just trapped in your own head. And that’s what makes you feel so icky. When will you understand that?” he smoothed his hand down your hair, cupped your cheek. He seemed to be upset that you were upset. Which did not make you feel better.

You reached out your arms, made grabby fingers. But Katsuki stood up without lifting you. You were not expecting that to hurt as much as it did. You felt like the air had been pushed out of your body. You scrambled to your feet, reaching over the edge of the playpen.

“Sorry, baby girl.” he shrugged. “I don’t hold babies who piss themselves. You’d need a diaper, and you don’t like diapers.” you stared at him as he strolled out of the living room, leaving you there.

Puppy was in the playpen with you, at least, and you grabbed the plush, burying your face in the soft material. Why were you crying? Why did this bother you? You refused to sob out loud, but puppy did absorb quite a few tears.

“Drink,” Katsuki said as he walked through the living room again. You could hear a movie playing from the room he and Deku shared. One that you had been asking to watch, too. He kept the door open, and you knew that he’d say it was so he could hear you.

So you drank, knowing how it would end. You stood up again, but this time you didn’t say anything. You only squeezed your eyes, spreading your thighs and listening to the trickling of urine.

You heard him clicking his tongue, refusing to open your eyes. He stepped into the playpen, cleaning your mess. No words were exchanged, and maybe they didn’t need to be. He stepped out again, watching you with a smirk as you plopped down to your bottom.

***

“What’s up here?” Izuku asked as he came home. You’d had another accident by then, although you weren’t sure it could really be called such. Not if you had squatted down to pee in as neat of a puddle as you could.

“Daddy,” you gasped out, feeling the tears coming again. Izuku didn’t walk towards you, though. Katsuki was grinning at him, walking across the room to claim a kiss from his husband. It was such a hungry kiss, their bodies pressing together.

“You’re wound up for someone who was home alone with the baby.”

“Like I’m interested in her right now.” Katsuki snorted. “She’s been very poorly behaved.”

“Has she?” Izuku frowned and glanced at you. Your face burned. You shouldn’t be the one ashamed, you thought. They had to know that you’d push back when things were too much. You rubbed your face with your hands.
“She seems sleepy, maybe she needs to be laid down. Where’s her diaper? Does she have a rash starting? You know that can make her a crab.”

“She pissed on me. On purpose. She wants to prove she doesn’t need a diaper. But she’s fine, pay attention to me.”

You couldn’t pretend that didn’t hurt. You ached for their attention.

“On purpose?” Izuku frowned.

“We’ll deal with her.” Katsuki shrugged. “But I want to deal with you.” he dragged his husband to the couch, yanking him down until there was only a pile of limbs. You stared, uncertain what to say or do. Katsuki was so strong, you thought as he maneuvered Izuku. They were stretched on the couch, Katsuki’s thighs spread wide while Izuku rutted between them.Hands ran down bodies, shoving up shirts.

You sat in the play pen, naked and lonely, watching.

“Baby girl,” the door opened, Eijiro taking in the scene. “Aww, look at you in the naughty box. Kacchan told me you kept wetting yourself. Maybe you’ll listen to him?” he hung his jacket and walked over to the couch where the other two were still tangled up.

“Welcome home,” Izuku was breathless, swollen lipped and flushed.

“Fuck, I always forget how hot the two of you are.” he sighed. Katsuki laughed darkly and continued mauling Izuku. Eijiro palmed himself over his pants, barely blinking. Want was blooming inside of you, and you could not stop the tears as they came.

You didn’t look up as the door opened again. You already knew. It was finally enough for Katsuki to release Izuku, who tried to fix his hair with his hands as all of them looked at you, finally.

“Well, what are we gonna do with her now?” Hanta asked. You hated the way that they spoke like you weren’t there.

“She pissed on me.” Katsuki grumbled. Eijiro nodded and reached into the play pen, pulling you out. He set you on your feet, his hand locked around your wrist. You were reminded of the fact that these were pro heroes, and they were much stronger than you ever could be. It felt like your toes were barely skimming the ground.

“Wait!” you begged as he sat in a chair, laying you over his lap. You were shaking your head. Eijiro arranged you carefully. No one was saying anything. No one was coming to hold your hands, or whisper sweet encouragement in your ears.

No one spoke. His hand fell on your ass, the sound of skin on skin ringing through the living room. You thought you could remain quiet. Don’t break, you told yourself. Don’t break, don’t show them.

It lasted about five smacks. He alternated which cheek he’d smack, but there was no real rhythm. You couldn’t guess, couldn’t prepare yourself. You could only tense up your whole body. It made everything hurt more.

“Please!” you wailed, back arching. “Please!”

“You were so bad.” Eijiro shook his head. He sounded so sad, it made your heart twist. “We can’t have you misbehave that way.”

“But you don’t listen.” you insisted.

“We do listen.” Denki said gently. “And we let you try without diapers, didn’t we? But you peed on the floor, Katsuki told us.” why were they missing it was because he wasn’t letting you use the restroom? You whined, frustrated. Denki finally came over to kneel in front of you, cupping your face in his hands.
“Daddy is going to finish with you. Han, babe? Hand me the pacifier.”

It was pressed to your mouth, and you felt like you had no choice but to take it. You suckled, grateful for the distraction. And you were getting their attention now, a little voice said. You whimpered as Eijiro continued your spanking. You didn’t bother counting the swats, it didn’t matter. He’d be done when he was done.

He was mad, you thought. They were all mad at you. The thought made tears well and spill, unchecked. When he was finished, he stood you up, keeping his hands on your shoulders. You sniffled behind the pacifier, sucking on it anxiously. Eijiro’s eyes were narrowed, and you hated seeing him upset with you.

“Think you owe an apology.” he grumbled. You walked with quaking knees to Katsuki. Your hands twisted as you went to stand there. His eyes, so red, so certain stared through you. You didn’t speak for a few moments until he reached out and pulled out your pacifier.

“You’ll get this back when you use your words and we sort it out. You want to be a big girl, this is me treating you like a big girl.” the blond shook his head when you whined. You inhaled deeply and blew it out slowly.

“I’m sorry, Daddy.”

“Oh? And what, exactly, is my baby sorry for?” he raised an eyebrow.

“Fo-for peeing on you.” you could barely choke out the words. He nodded and reached for you, wrapping you in a hug. He rubbed your sore bottom, taking some of the sting out of it. You pressed your face into the crook of his neck. Your thighs were parted, and you felt the diaper being slid up and taped closed.

“Show me how sorry you are, baby.” he spread his legs wide, sliding down his lounge pants. You didn’t need to be told twice, wrapping your hands around his eager erection and taking the tip between your fingers.

“That’s how a good girl behaves.” Hanta said with approval. You closed your eyes, feeling the heat in your face. Katsuki’s hands threaded through your hair, but he didn’t shove you down. He held you, letting you suckle him, go at your own pace. Your eyes fluttered open and locked with his.

It was a look of love. You could have drowned in it, not having realized that’s what you missed all day. You sucked hard, took as much of him in as you could. He was so wound up, it didn’t shock you when he came with a cry, arching off the couch. Your mouth was full of bitter spend, and you swallowed what you could, a thin stream of cum oozing from the corner of your lip.

“Messy girl,” Izuku teased, swiping your mouth with his thumb. “We shouldn’t tease you anymore today though, should we?”

You were in his lap in a moment, cuddled to his chest, just as you wanted to be. You refused to look at anyone else, letting him put the pacifier back between your lips, bouncing you on his knees slightly.

This had not gone the way you thought.

“No,” you whispered as you saw Izuku reaching for your jacket. He gave you a sympathetic look and walked towards you, helping you put your arms through the sleeves. You ought to have known, you thought, when he had woken you up so sweetly.

Everyone else had early shifts, so it was just you and Izuku. He’d lifted you out of bed, carried you to the change table and had you in clean clothes before you were even awake. You snuggled into him as he carried you, not to the kitchen, but to the living room.

“I think me and my baby can have breakfast on the couch today. As a treat.” he nuzzled your cheek. You giggled and snuggled into his chest, content and safe. You were the safest person in the world, you thought happily, there on Izuku’s lap.

He had breakfast ready; a bowl of fruit already cut up and some toast, already spread with butter. He fed you bit by bit. Normally, you hated hand feeding, but there was something else about this. You felt dreamy and floaty as he wiped toast crumbs from the corners of your lips.

A sippy was handed over, and you drank happily, still pressed to his chest. It felt like a reward or a treat. But you should have known better. After all, you hadn’t done anything particularly well to earn it.

After awhile, Izuku slipped his hand under your dress and gave your diaper a little squeeze. You whined and squirmed, although he ignored it. He set you on your feet and headed over to the coat closet. You didn’t worry about it, after all,there were a million reasons he could have gotten into it.

And then you saw your coat.

“It’s just an errand.” he soothed.

“But Daddy, I’m…”

“Shh, no one has to know.”

“But I’ll know.” you sucked in a breath. Izuku shrugged and took your hand. You would have liked to sit up front, but maybe if you could be extra special good, he’d let you wait in the car. That would be better, you thought. Maybe a little boring, but you happened to know that Denki kept a few little fidgets stashed here and there for his own busy hands.

It was worse when the pulled up to the big, busy shopping center. Smiling brightly as he nearly always did, Izuku went for the back door. He ignored the way you were frantically shaking your head as he unbuckled you.

“Please can’t I stay in the car?” you asked under your breath, as your eyes darted around. Izuku shook his head and kissed your forehead, lacing your fingers together. Your hands swung between you as you walked, making you feel all the more like a small child.

You kept your eyes down as you walked through the shopping center. People surged and flowed around you, and you were certain that every single one of them knew what you were wearing under your jeans.

“Izu?” you whispered after the third store, as he was looking at some pillows. He made a humming sound, not looking at you.
“I have to go to the bathroom.”

“Why is that a problem?” he asked casually.

“Be–because we’re in public.” you hissed, cheeks going pink. Izuku shrugged and grabbed a few of the pillows.

“I know you love your blankey, baby, but maybe we should get a back up, too?” he spoke in a regular voice, pulling you towards the blankets. You squeaked, looking around frantically. But no one seemed to have noticed, or cared if they did.

There were stacks and stacks of blankets, all kinds of textures and colors and materials. Izuku ran his hand down one stack, looking thoughtful. You squirmed next to him, not quite able to focus. You worked to hold your bladder. You were not going to piss your diaper right here in this store.

In the car, maybe. But not here.

It wasn’t like this was the first time this had happened. But when Katsuki had put you in this position, he had been much crueler about it. Izuku was acting like this was all expected. And maybe, you thought, he really did feel that way. Because you were a baby.

“Feel these,” he presented you with a few options, all in different shades of your favorite colors. You ran your palm across them and shrugged. “No,” he shook his head. “Feel them, darling.”

He grabbed your hand and made you really feel each blanket. The texture of the fabric, the weight of it, the weave. Some of them had silk bindings, and some of them didn’t. You lingered a little longer on the silkier offerings, and Izuku looked pleased as he held out one to you, putting the rest back.

“It’s nice.” you said stiffly, tapping your foot. “Can we go?”

“It is nice,” he agreed, examining it again. “We can rotate this with your other blankey. You wanna be tucked in for naps with this? Cuddle it at bedtime?”

“Izuku!” you spat. “Stop that!”

“Hey,” he took on a serious tone, eyes narrowing. “You know better than to talk to me like that.”

“We’re not home.” you sounded desperate.

“And that is all the more reason for you to behave.”

You trudged along behind him as he went to the check out, with pillows and blankets. You tried hard not to look like a sullen child who had been scolded .But, you thought, that was exactly how you felt.

“Now can we go to the bathroom?” you asked in a hushed whisper as you stepped out.

“Are you wet?” did he need a megaphone, you thought. Your ears burned as you thought about someone hearing you. You scowled and shook your head.

“That is what I want to avoid.” you managed.

Izuku gave you a fond smile and reached for your hand again, evidently intent on continuing to shop. You ripped your hand away and stepped away from him. It was then that Izuku glanced around. Gotcha, you thought smugly.

“I will spank you.” he warned under his breath. “I suppose we can go out to the car for it, but if you keep pushing, there are plenty of corners here that we can use.”

You froze, staring at him. He meant it, you realized. Your lower lip was quivering, and tears were stinging in your eyes. When had you become such a cry baby? Izuku paused and reached into his bag. He found a pacifier, along with a mask. Before you could say anything, the pacifier was in, and the mask was placed over your face.

“Behave,” he said it like he was begging, like he wanted that for you, too. This time, you let him hold your hand as he briskly began to head to another store.

“Midoriya!” a voice called. Both of you paused. Izuku looked curious, and you felt like you wanted to sink into the floor.
“How lovely to see you.”

Iida, you realized. You had met him in passing a time or two at parties. Your hand went tight around Izuku’s, and your bladder ached. You couldn’t wriggle or squirm. He’d know. You clamped your lips tight on the pacifier. What were you going to do.

“Iida, hi!” Izuku said brightly. “Doing some shopping?”

“Oh, just a few odds and ends.” he nodded at the bags in his hands, then looked at you with a kind smile.
“It’s great to see you, I haven’t in so long. How have you been?”

What to do? What to say? Your brain felt like it was slogging through molasses.

“She has a cold.” Izuku said quickly. “We just ran out for some new pillows to keep her propped up.”

“I’m sorry to hear that.” Iida frowned, pushing up his glasses. “Rest and hydration!” he seemed to expect you to say something there.

“She lost her voice.” Izuku added. “She’s not trying to be rude.” Iida nodded and then began to talk to Izuku about something else. You couldn’t really follow along, trying as you were not to piss yourself.

But it was a losing battle. Your bladder had gotten used to you releasing whenever you needed. You tried to pinch it back, but it wasn’t like you could cross your legs or move too much. You bit back a whimper as you lost the battle, wetting your diaper.

At least the din of the shopping center kept you from being heard. Small mercies. Tears pricked at the corners of your eyes, and you squeezed Izuku’s hand as subtly as you could. He glanced at you and smoothly began to give good byes to Iida.

“I better get our girl here home for rest.”

“Goodness, yes!” Iida looked at you, startled. “She must be running a fever. Take care. And get rest!” he waved and headed off. You gasped as Izuku put an arm around your waist and pulled you close.

“Aww, baby doll. Did you pee? Are you wet? Need a diaper change?”

“Stop,” it was muffled behind your pacifier.

“Let’s go home.” he wasn’t even going to change you there? You whimpered as he walked you to the car. As soon as you were outside, his hand went to the back of your jeans, giving your swollen diaper a little squeeze.
“Better hurry, huh? Don’t want a leak, do we?”

You stared at him as he set you in the back seat again, making sure to buckle you in carefully. He set the bags next to you, gave your cheek a fond pinch and laughed when you glared.

“What’s wrong?” Hanta was home when you walked in. You shook Izuku’s hand away from you and darted for him, arms out stretched. He lifted you up and settled his hands under your bottom as your arms locked around his neck.
“What’s the matter, baby?”

“She wet her diaper in the mall.” Izuku said casually as he hung up his jacket. Hanta kiss the top of your head and rubbed your back.

“Aww, you’re just a baby, it’s okay.” he moved to take off your mask, clearly surprised at the pacifier. “You don’t usually–.”

“She got upset, I had to keep her calm. But what she’s really mad about is that we saw Iida.” he said it casually, going over to strip off your coat as he spoke. You tried to fling him away and were rewarded with a smack to the hand.
“Enough.”

“She’s cranky.” Hanta noted quietly. You wanted to scream that you weren’t cranky, you were pissed off and in a wet diaper and he didn’t let you use the toilet and you were embarrassed and you didn’t want to do this! But you realized that saying
anything like that would just make them think you were cranky.
“Come on, love.” he bounced you a little. “Let’s go ahead and get a fresh diaper, and out of those stiff jeans and into something comfy. And then we can watch TV in my room.”

“You think she’s earned TV?” Izuku raised an eyebrow. “She just got snotty with me.”

“She needs to decompress is all.” Hanta carried you to his room, ignoring the way you were brushing at your eyes. He changed you and put you in one of his own over sized shirts, pleased when you snuggled up next to him, sulking a bit but still watching television.

He loved getting the chance to rescue you, he thought happily.

Chapter Text

“But we’re not going anywhere.” you noted. Eijiro nodded in agreement as he finished dressing you in a cutesy, frilling little dress. You frowned at the hem, tugging it. Your diaper was peeking out from the hem, you knew that.
“And this doesn’t fit.”

“Yes it does,” he disagreed. You watched as he reached into the dresser and rummaged for a second, beaming as he held an item in his hand. He threaded your feet through, and you realized it was a diaper cover. Not just a plain one, with the frosted plastic. This one had silky fabric, with bows and lace at the waist and legs. There was even several rows of lace on your ass, making the skirt puff out a little bit and drawing attention to the face you were diapered.

“What the hell?” you grabbed your dress, pulling it up a little to look at the cover.

“Hey,” Eijiro scolded gently. “You know better than to talk like that, don’t you?”

“But what is this?” you glared at him.

“It’s just part of your outfit,” he soothed, putting on a pair of socks with lace at the cuffs. You groaned, reaching for the cover to pull it off.

“I don’t need this, you never make me wear things like this!” Eijiro didn’t respond as he set you on the floor. You turned to march to the kitchen for breakfast, your face growing hot when you realized that the pants made noise

There was a distinct crinkling sound as you walked. Your face burned when you arrived in the kitchen. Denki didn’t even pretend he didn’t think you were adorable, hurrying over to scoop you up and spin you around. He patted your bottom, smirking when the plastic rustled.

“You look so cute! Do you feel cute? It was so nice of Eiji to get you all dressed pretty, wasn’t it? Did you say thank you?” he was going a mile a minute as he put you in the high chair. He placed a bib around your neck, tying it just right. You grabbed the bib and shook your head.

“No no,” Izuku was carrying a bowl. “You want to keep your outfit cute. Here,” he set down a bowl of oatmeal. To your surprise, he hadn’t given you a spoon. You stared at the hot cereal before turning to look at him again.
“Dig in, babe.”

“I need a spoon.” you said tightly.

“Nope,” Katsuki popped the ‘p’ as he lifted his cup of tea, taking a sip and giving you a triumphant look. You glared at him, the implication falling over you, although you didn’t want to say it outloud.

“I will wipe your hands clean after.” Hanta said, focused on his breakfast. The oatmeal did look good, you thought. There were berries, real fresh ones, nothing that had been frozen. You sighed and reached out, plucking one of the berries.

“Is that good, baby girl?” Denki asked. You ignored him, scooping more cereal and sucking your fingers clean. No one else said anything, but no matter how careful you were, it was messy.

The bib had kept your dress clean. But you’d never admit that to the rest of them. As he had promised, Hanta was there to wipe your face and hands. He removed the bib and set you down out of the chair.

They usually carried you around. But today, they seemed determined to let you walk. They were watching you as you tried to step carefully, keeping the crinkle sound dampened. But no matter how you walked, the pants rustled.

“You’re just so cute today.” Izuku said, sitting on the couch and watching you plop on the floor. You shook your head, looking towards the television. Maybe you could ignore it, you thought. If you were still enough, everything would be fine.

“Don’t you all have work today?” you muttered.

“No, sweetie, we’re all home today.” Hanta beamed at you. You stood up, eager enough to head towards your playroom. Eijiro caught you as you tried to hurry by, setting you on his hip.

“Don’t you want to hang out with us? We want to hang out with you.” he kissed your cheek and bounced you as he went to take a seat. “Smile,” he was giving his own toothy grin as he looked towards Izuku.

He had his phone pointed towards the two of you, snapping pictures. Eijiro set you on your feet and turned you around so you leaned into his chest. He lifted up the back of your dress, putting the lacy cover on full display.

“It was such a cute idea, Eiji.” Denki sighed.

“I know. Do you like it, baby?” he asked you, reaching to pat your bottom, making it even noisier. You shook your head, cheeks on fire. He laughed, spinning you around, holding your dress up in the front to display that cover again.

“These are great pics, you’re so cute.” Izuku sat down. You shook your head, covering your face with your hands.

“Don’t be like that.” the redhead coaxed. “Is it because you’ve gone too long without us making you feel good? Is that it?”

“I don’t–.” you began.

“Shhh,” Eijiro’s legs spread wide. He settled you on his thigh, facing outward. He began to bounce his leg, the crinkle of the diaper cover and the diaper so loud. He reached for your hips, adjusting you.
“There you go.”

You really hated how well they knew your body. You gasped as he began to help you move, humping his thigh through your diaper. The feeling was muted, of course, but there was still friction on your clit, and that was what you loved.

“I know good and well when she’s getting it good.” Izuku laughed. “Her eyes always go cloudy and her lips are slack.”

“It’s too hard for her to think.” Denki agreed. “We should keep her dicked down and dumb. It makes her happy, and we’re happy when she’s happy. So it’s really for the best for everyone.”

“More,” you gasped, resting your hands on Eijiro’s knee. You ground down harder, seeking out the perfect amount of pressure.

“You’re so hot.” Katsuki noted. He walked over to sit in front of you as you were seeking pleasure in Eijiro’s lap. He reached down his lounge pants, his hand pumping as he watched you, barely blinking.

The diaper cover crinkled loudly, and you found yourself not caring. You were so close, almost there, gasping and moaning.

“Baby girl,” Denki called. “Are you gonna cum? You gonna make that diaper all sticky? Don’t worry,” he cooed. “We’ll get you in something clean.”

“And if you soak the diaper, we know that it won’t leak, don’t we?” Eijiro squeezed your hips. Your head fell back as you thrust your hips. In only a few more moments, you were cumming. You gripped Eijiro’s knee, glad that they were so strong and it was so hard to hurt them. You never wanted to hurt them, you thought deliriously. You wanted to make them happy.

You moaned loudly as you came, grinding down as hard as you could. You felt dizzy, nearly falling forward. Eijiro wrapped his hands around you and pulled you into him. He rubbed your thighs, trying to help you calm.

“Fuck,” Katsuki groaned, a wet stain spreading on his gray pants. Izuku mockingly clicked his tongue, going to help his husband off the floor and reach into his pants with a few wipes.

“So messy, just like the baby.”

“Shut it, nerd.” but there was no heat to his words. You and Eijiro stood up, and Katsuki laid on the couch, having kicked off his pants. You were laid on his chest, and he reached down to cup your diapered ass.

“Looks like both of you can rest here.” Izuku declared, pulling a blanket around you. You hummed in content, sinking into the feeling of being held and fingers in your hair.

Chapter Text

“Why?” you demanded. “Just why? Why would you spend this kind of money on something? And what if someone saw?” even now your eyes were darting around, your face feeling like it was on fire.

“The windows are tinted.” Hanta said. “And this will keep you safe and comfortable when we go on long car rides.”

“Why are we going on long car rides?” you knew you sounded whiney, and the fact you were in a snap scratch onesie and a little skirt over it didn’t help. Hanta ignored you, adjusting the bags in the backseat.
“Well, I won’t ride in it. I’m an adult and I can decide where I go. I’m not going.” you set your chin. Katsuki sighed in that way that let you know you were starting to get on his nerves. When you got on his nerves, you knew that a spanking could be had.

But this, you thought, this was worth fighting about. The car seat was exactly like the ones that little kids sat in, with the high back and the five point harness. It was cushioned, and Hanta had even attached a little fan to it.

“You don’t make the choices.” Katsuki said tightly. You wanted to cry as he put you in the carseat. You tried to push at him as he held you down, one hand on your waist, while the other was guiding your arms through straps. He had the chest clip down and the crotch buckles done in just a moment.

“No way, I’m not doing this. Let me out.”

“When you ride in my car, you ride the way I say.” Hanta bent to put his head in the car. “And you’ve made it very clear that you can’t be left alone. So you’re coming with us, and you’re going to behave.”

“I won’t! I won’t!” you were squirming in the seat. Hanta put his hands on your thighs, stilling you. Slowly, you looked him in the eye.

“You will not like what happens if you choose not to behave.” he warned. You went still, and he gave your legs a little squeeze before backing away from the door. Your door was closed and the two of them got into the front seat.

If you swiped at your eyes with frustrated tears, no one said anything. You were quiet in the car for awhile.

You squirmed in the seat. The straps had been done tightly, and you swore the buckle was pressing between your legs in all the right way. Was that done on purpose? Probably, you thought to yourself, nothing was even on accident when it came to any of them.

“It’s nice to see you calming down.” Hanta noted, glancing at you in the rearview mirror. You huffed and looked away, still annoyed. You wriggled more in the seat, realizing that your diaper was crinkling as you did.

Why didn’t they turn on the radio? Katsuki turned in his seat so it was easy for him to look at you. Your skirt had ridden up, and your crotch was being pressed by the buckle again. You gave him a sad look, hoping that he’d get the hint.

“You’re fine, babe.” he cooed. “Are you too hot? Hanta, turn on the AC.” the dark haired man leaned over and flicked it on. You said nothing, noting that the buck was making you feel a little stimulated. And all the squirming hadn’t helped.

“What’s wrong?” Hanta asked. You worked your mouth, uncertain what to say. How did you say that your pussy was starting to tingle in your diaper and you couldn’t reach in? How did you say that was a problem for you?

“Go ahead and hump your diaper.”

“Daddy,” you stared at Katsuki. He just gave you a smirk, making it clear that he had no plans of looking away.

“You know that you’re always calmer after you cum. You’ll have an easier time napping in the car.” he coaxed. You didn’t want to, but Katsuki was watching you and so was Hanta, sneaking glances in the rearview.

“I want you to touch me.” you said plaintively. Usually that would make any of them melt, any of them rush to you. But not this time, Katsuki just hummed and gave you a patronizing look.

“If you can be good, when we get ready for bed tonight I’ll touch you. I’ll finger that little cunt and put you in a nice dry diaper. Then we can cuddle to sleep. Is that what you want?”

“Yes!” you gasped, the thought making you feel wet inside the diaper. You humped, rolling your hips to get some of that delicious friction just where you wanted it to be.

“There you go, keep it up.” Katsuki coached. “I know that’s not what you wanted, but you’re being such a good girl. You’re gonna feel so much better, aren’t you?” you whined and moaned, feeling sweat beading at your hairline as you moved against the restraints of the seat.

“Are you close, precious?” Hanta asked. “Are you gonna make a sticky mess in that diaper? We aren’t stopping for awhile, so you’ll have to sit in it. You like that though, don’t you? Silly little slut.” he chuckled.

“Don’t tease,” Katsuki laughed softly. “She’s just a dumb slut, but we shouldn’t make fun of her for that.” he watched you bouncing in the seat. With a gasp, you came, fingers going tight on your straps.

“There it is,” Hanta praised. “Oh, what a good job.” you slumped in the seat. Katsuki reached back painfully and eased a pacifier between your lips, not surprised when you took it without a fuss. He watched as you relaxed, as your diaper swelled between your thighs.

“Such a good girl, aren’t you?” Katsuki sighed happily. “Just be still, baby, we’ll be there soon enough and I’ll change you.”

You didn’t love sitting in a wet diaper, but they’d put down plenty of powder. You leaned your head back against the seat and stared at the ceiling, pacifier still tucked into your mouth. The radio was finally turned on, and you ignored everything until the car was pulling up a driveway you didn’t recognize in another town.

“Izuku has some work to do here for a few days, so we’re all going to stay here in a little AirBnB.” Hanta stopped the car. Immediately, Denki was leaving the house. He opened the door before you could even reach for the harness buckle.

“Baby! We were waiting for you.” he beamed. He undid the belt and lifted you up. “Sweetheart, did–?”

“Why bother asking?” Katsuki cut him off. “You know she can’t keep her little diaper dry. Go take her in and change her diaper and give her a cuddle, like I know you’re dying to do.” he got out of the car himself and stretched. It was nice to bury your face in Denki’s shoulder as he carried you in.
