Chapter Text

It started like an itch under his skin. An itch that happened to only be present when Midoriya Izuku was around. Shouto had initially assumed that it was competitiveness he felt toward the smaller boy, but the more time he spent around the other boy, the more he realized that that wasn't the case.

It was all very confusing. It was like his mind was consumed with the other boy. Secrets just spilled from Shouto’s lips whenever Izuku was around him. It was like he wanted to tell him anything and everything about himself. Shouto wondered if it was just a simple crush or if it was something more. Unfortunately, they couldn't possibly be mates, Izuku was a Beta.

Little did he know, Izuku had been feeling the very same itch, and neither boy fully understood what it meant until after the events with the Hero Killer. Shouto had immediately ran to Izuku’s aid when the other boy asked for his help. They fought so easily together, like their bodies were meant to be working alongside one another.

They were now at the hospital, battered and bruised from the fight. Izuku and Shouto sat with one another, talking.Tenya had decided to rest in the bed across from them as it was “imperative to refuel (his) energy”.

Shouto glanced at Izuku’s scarred hands, the injuries he gained while trying to open Shouto to his left side. He felt his chest clench, knowing that that the scars Izuku bared were for his sake. Without thinking, he took the smaller boy’s hand in his to study it further. It was smaller, but rough from fighting. He could be imagining it, but it felt like there was electricity coursing between their joined hands.

Izuku could feel his face burning as he watched the other boy lift his hand up. This was technically the closest he'd ever been to the taller boy. Shouto was so handsome and Izuku couldn't help but subtly scent the air, taking in his soothing scent. This only served to cause his face to burn even brighter.

“I'm...thank you,” Shouto said, hesitantly. He unconsciously gripped Izuku's hand tighter.

Izuku was was caught off guard and sputtered out, “W-what?” He was having a hard time focusing with Shouto’s piercing eyes meeting his.

“Your hands, you hurt yourself for me,” Shouto clarified. “You're the first person to ever do something like that for me.”

Izuku smiled brightly, “Don't worry about it… it's what friends do.”

They remained in relative silence for a few moments before Shouto spoke again.

“I'm not very familiar with the concept of ‘friendship’, so I don't know what the protocols are,” His face was completely serious.

Despite Shouto’s serious tone, Izuku couldn't help but let a giggle escape from his lips, “You're...a funny Alpha, Todoroki.”

Shouto’s face remained stoic, “It wasn't a joke.”

Izuku stopped laughing to think for a moment. Shouto seemed like he hadn't seen a lot of affection growing up, and Izuku's heart warmed for the other boy.

“You haven't been hugged a lot, have you, Todoroki?”

“Not really--” Before he could finish his sentence completely, Izuku wrapped his arms around Shouto’s shoulder’s, careful of their injuries.

Shouto became rigid as the smaller boy began pressing his weight into him. Awkwardly, he brought his own arms to wrap around Izuku. The smaller boy snuggled in closer, seemingly on instinct. He buried his face into Shouto's neck, a little closer to his scent glands than what was considered appropriate. Shouto became a little more confident and brought his face to the crook of the smaller boy’s neck as well. They slowly inched toward one another’s scent glands, unknowing even to themselves. Next thing they knew, they were scenting one another, becoming a little intoxicated by the scent.

The scent of the other boy was starting to slow down Shouto’s processing and he couldn't put together why Izuku’s scent was so sweet and alluring. He smelled like heaven and he just wanted to bury his face in the smaller boy’s neck forever.

Izuku was equally overwhelmed. Shouto’s scent was so comforting and safe. It was as if the rest of the world was disappearing as he was enveloped in Shouto’s protective embrace. He could feel himself becoming limp and malleable against the mix-haired boy. And he just felt so warm, the sweetest warmth he'd ever experienced.

It was only when he felt a little slick leave his body that he realized what was happening. Even in the haze of Shouto’s scent, a sudden oncoming heat was unmistakeable.

Shouto flared his nostrils as Izuku’s scent became even sweeter. In his own haze he realized that that should mean something to him.

Izuku started muttering, “...Doesn't make any sense...took my suppressants… didn't nest…”

Shouto had a sudden moment of clarity, “You're an Omega.” He wanted to facepalm, it was so obvious to him now. He removed his face from Izuku's neck to get a better look at him.

“Yeah,” Izuku knew he should probably move but he really didn't want to. “It's just… I took my suppressants, so I don't get why my heat is starting.”

“We’re probably mates,” Shouto said, nonchalantly. He'd suspected it earlier but he had rejected the idea when he thought Izuku was a Beta.

“Like True Mates?!” Izuku exclaimed. “Us? How--” He was interrupted as a sudden rush of slick left his hole, soaking the back of his hospital gown. He could feel his cock hardening, leaving a tent in the front.

Shouto was in a similar state, his dick hardening as the scent of Omega-in-heat filled the air.

“Yes, we likely didn't know until now because we haven't been in such close proximity,” Shouto said. “I've felt really… drawn to you. Have you also felt it?”

“Yeah,” Izuku nodded, “ I thought it was just because I wanted to help you. But you smell like…”

“Home,” Shouto finished for him.

There was a moment of complete quiet between them. They stared into each other’s eyes, blue and gray meeting green, and unspoken conversation between the two of them. Their eyes traveled down to each other's lips and in an instant they were attached to one another.

The first kiss was light, hesitant. They pulled away just for a moment before connecting once again, this time with far more ferocity. They took their time exploring one another, taking in the unique taste of their mate. Both boys were obviously inexperienced. Shouto tentatively pressed his tongue against the seam of Izuku’s lips. Izuku allowed him access but neither boy really knew what to do with their tongues. A droplet of their mixed saliva dripped down Izuku's chin. They didn't seem to care about their inexperience, as they were simply enjoying taking each other in.

Izuku moved to sit in Shouto's lap. Their erections brushed together, causing both boys to groan. After a few more minutes of kissing, they separated. They were both breathing erratically, eyes dilated.

“What now?” Izuku asked, trying to restrain himself from grinding against Shouto’s thigh. His pseudo heat wasn't nearly as bad as his actual heat, but he was getting a little desperate. He was pretty sure that the back of his gown was completely soaked through and his hole was aching to be filled.

“Now… would you like to have sex with me, Midoriya?” Shouto asked.

“Why...why do you have to ask like that?” Izuku asked, blushing deeply.

“Ask like what?”

“Like…” Izuku trailed off. “Never mind. Yes!”

“Yes, you would like to have sex?”

“Jeez, yeah,” Izuku replied, this guy was freaking embarrassing.

Shouto nodded and pressed his lips to Izuku’s softly before bringing a hand to the string of the smaller boy’s gown. He kissed along Izuku’s neck as he loosened the tie on the gown. Izuku bared his neck without thinking, an act of submission that was normally only seen between bonded pairs. Shouto itched to bite into the scent gland, but he refused to do that when both were slightly intoxicated by new mating pheromones. Instead he nipped lightly at the spot, leaving a temporary bond. It shot a streak of pleasure throughout Izuku's body and he moaned.

With the gown now untied, Shouto pulled the article open, helping Izuku push it off his arms. Without any undergarments, Izuku was left completely nude to Shouto’s completely clothed. Izuku, embarrassed, tried to use his hands to cover his lower half.

Shouto shook his head, “I want to see you, Midoriya.” He patted Izuku’s hands.

Izuku blushed, “I’ll feel better if you're naked too.”

Shouto nodded and shrugged out of the hospital shirt he was wearing. His muscles rippled with the movement and Izuku could feel his hole widening at the prospect of being fucked by such a strong Alpha, slick soaking the bedding. Shouto somehow removed his pants with the most grace Izuku had ever seen. His large cock sprung from its confines, causing Izuku to shriek slightly.

Shouto looked alarmed, “What’s wrong?”

“How is that… thing… supposed to fit?!” Izuku exclaimed.

“Midoriya, my penis is standard Alpha size,” Shouto said. “Omega bodies are designed to take them.”

“Standard?!” Izuku’s face was practically tomato colored at this point. “I'm even more self conscious now.” He knew Alpha dicks were big, but he didn't know they were that big.

“You have nothing to be self conscious about,” Shouto said. “You're very beautiful.”

Izuku's heart raced, no one had ever called him beautiful before. He knew that Shouto wasn't the type to flatter dishonestly. Slowly he removed his hands from his leaking erection, leaning back onto the bed, effectively revealing himself to Shouto.

Shouto’s heart was racing. He'd never felt so flustered and out of control in his entire life. Izuku was so perfect, with his mop of green curls and his lean muscle. He knew that Izuku was likely self conscious since Omega cocks were small and basically vestigial. However, Shouto couldn't help but find the pink, leaking member to be beautiful as well. In comparison to his hard and angry looking cock, Izuku's was far more appealing to look at.

Shouto kissed along Izuku’s chest, toward a set of pink, puffy nipples. He briefly kissed the tip of one, eliciting a moan from the green haired boy. They were incredibly sensitive and Shouto made a mental note to test the limits of that sensitivity at a later time.

He made his way down Izuku’s body until he reached the hard cocklette straining between his legs. It was leaking precome and Shouto muttered “Beautiful” before taking a taste for himself. Izuku cried out and laced his fingers through Shouto's hair. He had heard rumors that Omega cum was sweet but he didn't believe it until now. Even Izuku's precome tasted like candy. He was struck with the desire to make the green haired boy come for real but Izuku interrupted that train of thought.

“I want you inside,” Izuku moaned, spreading his legs. His entrance was now on full display. It was so wet and wide already. Omega’s were really incredible.

Shouto licked his lips, if the rumors about Omega cum was true, then he could only imagine what Izuku's slick tasted like. Not to mention the fact that it was leaking out so steadily now, it'd be like a drinking fountain of Izuku's concentrated scent. Shouto pressed his tongue flatly against the hole, causing the shorter boy to moan loudly and tug at his hair. The flavors of Izuku's slick burst in Shouto's tongue and he dove in for more, pressing the tip of his tongue in. He twirled his tongue along the rim before thrust in entirely. He used his lips to massage at Izuku's swollen rim as he twisted his tongue in and out of the channel. He then decided to press in a finger, feeling the velvety inner walls. He added a second finger and began using them to spread Izuku open. He curled them in just the right direction and the shorter boy shrieked as he came unexpectedly, tears streaming down his face. Shouto had brushed against a really good spot. Izuku tried to calm his breathing as he glanced at the little drops of his come that were splattered across his abdomen.

Shouto lifted himself to lick up the mess. The sight alone had Izuku hard again; Omegas in heat, even pseudo heat, had incredible libidos.

“Todoroki...please,” Izuku moaned. “I need you right now.”

Shouto sighed, “I don't have protection.”

“It's fine, I won't get pregnant,” Izuku grabbed his legs so his pink hole was even more exposed.

Shouto groaned, and lined his leaking member up to the gaping entrance. Slowly, he pressed in. There was little resistance but Izuku fit around him like a glove. Somehow, he fit his entire length inside, and Izuku whimpered. Shouto stilled.

“Are you hurt?”

“No… just…” Izuku took in a shuddering breath. “Feels good.”

Shouto allowed a rare smile to spread across his face, “I feel good, too.”

They both smiled at one another and Shouto slowly started to move inside.

Izuku sighed out an adoring, “Todoroki.”

“Call me...Shouto,” Shouto gritted out as Izuku clenched around him. He thrust forward, taking the breath from both of them.

“Shou… Shoucchan,” Izuku wrapped his legs around Shouto's hips, ignoring the slight pain in his injured leg. “Me too.”

“Izuku,” Shouto said, picking up his pace.

It was their first time, so it was a little awkward, but they eventually found a rhythm that worked for them. Izuku screwed his eyes shut when Shouto found his prostate again. The taller boy made a point of hitting it with every thrust after that. He could feel his own knot forming and he knew he wouldn't last for much longer. He started to slow down as his knot dragged along Izuku's rim.

Reaching his hand to envelope Izuku's cock, Shouto began jerking the other boy off. The shorter boy came for a second time with a cry, his asshole clenching tightly. This caused Shouto to jerk forward and lock inside, his knot keeping them in place as he came deep within. Shouto couldn't help the split thought of what it would be like if this were a real heat. If he could impregnate Izuku and fill him with his pups.

They collapsed on the bed and carefully tried to arrange themselves so Shouto wasn't crushing Izuku. They flipped over so Izuku was lying on top of Shouto instead. They spent several minutes just enjoying post-coital bliss and scent marking one another as they waited for Shouto's knot to go down.

“I thought you were a Beta,” Shouto said. “Do your heat suppressants mask your smell?”

Izuku nodded, “I don't intentionally hide my secondary gender, but people just assume I'm a Beta and I don't correct them… the scent masking is just a side effect… and it is easier to be a hero if you're a Beta or an Alpha anyway.”

“What makes you say that?” Shouto asked. “I really respect you as a hero. Just look at what we did today.”

Izuku got a little teary eyed at the compliment but spoke again, “Not my capability. Like…other people won't respect me as a hero.”

“Well, those people are shitty anyway,” Shouto replied, bluntly.

Izuku laughed.

“Their opinion isn't what makes you a hero, it’s your actions.”

They spent the duration of Shouto's knot talking about whatever came to mind. At some point they became more aware of their surroundings. Izuku's eyes widened as he glanced around the hospital room, realizing that Tenya was no longer in his bed. They had completely forgotten where they were.

“We… I can't believe we did it with Iida in the room,” Izuku stared widely at Shouto.

“He must have left,” Shouto said, seemingly unfazed by being caught.

“How did we not even realize where we were? We literally did it with Iida sleeping right next to us!”

“You were in pseudo heat and I was intoxicated off of it,” Shouto said. “I've heard that True Mates get pretty into it. Iida probably left pretty early anyway.”

There was a knock at the door, and Shouto swiftly yanked the blanket to cover the two of them. The door slowly opened and a blushing Iida peaked his head in, eyes closed.

“The staff are becoming upset with me,” Tenya said. “I can no longer guard the door. You need to get dressed.”

“Guard?” Izuku asked.

“When I awoke to the two of you removing clothes, I took it upon myself to guard the door as you defiled one another,” Tenya replied. “See it as payment for the debt I owed you today.”

“Uh, thanks, Iida.”

Tenya nodded and closed the door.

Izuku groaned into Shouto's chest, “We’re so stupid.”

Shouto started making a noise and it took Izuku a minute to realize that the taller boy was chuckling. It was such a shock that he nearly didn't register it. Izuku started laughing in response to the other boy's laughing.

Shouto sobered once more and said, “I would like to properly court you, Izuku.”

“I'd like that, Shoucchan.”

The itch was finally sated.

Chapter Text

Courtship was far more difficult than Shouto had originally anticipated. He knew that it was the proper thing to do as a “respectable Alpha” but it was an awful lot of work for something that seemed so simple.

It wasn't the dating that was difficult--spending time with Izuku was always great--but rather the etiquette that was involved. When Shouto said “courting” he meant in loose modern terms. Meaning they'd date and share gifts for three months before spending a heat together. Midoriya Inko had other ideas. For starters, they began their courtship all wrong by sleeping with one another from the very start. Luckily, Inko forgave them on account of them being True Mates. It wasn't everyday someone met their mate. Hell, it wasn't every year. However, she also insisted that they go through proper chaperoning, which just ended up being a lot of of three-person dates with Shouto, Izuku, and Inko. Shouto liked Izuku's mom a lot, but he'd be lying if he said he didn't want to make out while watching movies with his mate.

She allowed scenting and was cool enough to pretend to need the bathroom so they could kiss a couple times without being watched. She also pretended not to know that Izuku owned a plethora of Shouto's clothes and slept with them (amongst other things). She understood that, as True Mates, they were drawn to each other and comforted by one another's scent and touch.

Shouto's father was an entirely different case. Endeavor completely rejected the courtship. Though he admitted that Izuku's quirk was similar (or literally exactly like) All Might’s, he felt that Shouto would be much better off with an Alpha with a strong quirk. He looked down on Izuku's status as an Omega, even though the boy had proven himself strong enough on multiple occasions.

Nearly three months later it was still a point of contention. Inko loosened her grip on the terms of the courtship, allowing them more time alone, while Endeavor never budged.

It wouldn't matter to Shouto if they were older, but their mating would not be recognized by the government unless consent was provided by a guardian. He would ask his mother but she was no longer considered his “guardian” while bound to a mental institution.

The document essentially granted True Mates the same rights as a married couple, but with the added bonus of mate accommodations. It basically meant that the couple could not be separated by the school, or any other public facility, for more than an hour. Amongst other things.

“I'm giving Izuku my bite no matter what you say,” Shouto gritted out. “So you might was well sign the document.”

Endeavor looked close to going completely ballistic, “I'm not accepting your courtship with one of those meek fuckholes. If you want to fuck him that's fine, but a bond is unacceptable.”

Shouto had to hold back the string of curses he had lined up for his father over the course of that sentence and opted to breath deeply, “It’s a statistical fact that the bond of a True Mate makes both parties stronger. Not just mentally but physically. I have already seen improvement in controlling my quirk since forming a partial bond with Izuku, imagine the potential if we completed the bond. Even if you don't believe in Izuku's strength, you can't ignore the fact that his presence will increase mine. And isn't that the goal? For me to be the strongest?”

Endeavor appeared slightly tamed for the moment, “And you can't simply gain strength from fucking him?”

Shouto shook his head, “True Mates are more than just sex. We need each other's company. Especially after we properly seal our bond. Long periods apart can also negatively affect our health, which is why I need this document to protect us.”

Endeavor huffed, smoke coming from his mouth, “And you intend to bond no matter what?”

Shouto nodded.

Endeavor thought for a long moment.

“I'll allow it, on one condition,” Endeavor smirked. “You have to spend the first heat at a Heat Hospital.”

A Heat Hospital was basically a hotel in which couple spend their heat together. It was only called a hospital because they had a strong focus on sanitation and heat nurses would ensure the safety of the guests. People were often turned off of the hospitals because guests were under constant surveillance to ensure the best possible service. Sheets were changed immediately after guests left the room. Kitchens were stocked with whatever guests wanted, whenever guests wanted it. Couples alone often run out of food or make a huge mess of their house, so Heat Hospitals can be incredibly beneficial. If you can get over the whole “constant surveillance” part. Endeavor likely knew this would embarrass Shouto and hoped it would turn him off of the whole mating thing.

Shouto could feel a deep blush spread across his cheeks, but he said, “Deal.”

~~~

It had been officially three months since Shouto had begun courting Izuku, so it was now time for the boys to share a heat together. Izuku stopped taking his suppressants and he was expected to begin his heat tomorrow. They were at school for the last day in order to collect their homework.

“I can't believe you're getting bonded tomorrow, Deku!” Ochako exclaimed, excitedly. “Are you nervous?”

Izuku shook his head, “It’s Shouto, so I’ll be fine.”

Meanwhile, Kirishima was harassing Shouto across the room.

“Sex for a week,” He clapped Shouto on the back. “You fucking badass.”

“You're annoying,” Shouto huffed.

Kirishima just laughed.

Izuku and Shouto made eye contact and Izuku decided to walk across the room to snuggle up against Shouto’s side. The mix-haired boy could feel his face burn slightly as his mate rubbed his face against his neck, scenting him.

Katsuki glanced from where he sat and growled, “Stop being so fucking disgusting, shitty Deku.”

Izuku simply stuck his tongue out and said, “Don't be jealous, Kacchan.”

Katsuki was basically foaming at the mouth at this point, but Kirishima patted him on the head like a dog.

~~

Izuku was just feeling really clingy today, he couldn't explain it. Any time he got the opportunity, he would cling on to Shouto. It was now lunch and that fact still stood.

That had been sitting beside each other but slowly the green haired boy shifted himself closer and closer until he was on Shouto’s lap in the middle of lunch. Burying himself deep inside the crook of his mate’s neck and breathing in the soothing scent deeply.

Shouto certainly didn't mind the attention, though he wasn't really one for PDA. That being said, neither was Izuku. Handholding tended to be the max for the both of them. By today Izuku was just getting clingier and clingier, and Shouto could feel a sense of protectiveness wash over him. It nearly knocked him out of his chair, the feeling was that strong. He just wanted to whisk the small boy away and keep him safe from the rest of the world. Suddenly every Alpha in the room seemed like a threat, and Shouto glanced across the table to glare at Tenya, who was trying to eat his food without looking at them.

Tenya cleared his throat, plugging his nose, “I believe… Midoriya’s heat is starting. You're rut, too.”

Shouto blinked before saying, “Shit.”

Izuku lifted his face from Shouto’s neck to study his face, noticing his distress. He bared his neck to his Alpha in hopes of calming him down.

Shouto sighed audibly before gently nipping Izuku's neck and standing with the boy in his arms. He made quick work of informing the school of their situation and leaving for the Heat Hospital of their choice.

~~

With his dad’s kind of money, it was a really nice place. It looked like a really expensive hotel and they had one of the nicest suites there. If Endeavor was good for one thing, Shouto decided it was probably that. He didn’t really care about the money but he knew Izuku would be comfortable here.

They were escorted to their room, which was complete with a bedroom, kitchen, living room, and bathroom. The bed took up essentially the entirety of the bedroom. Izuku lept from Shouto's arms and ran to it, grabbing the bags of blankets that had already been delivered to their room. The smaller boy launched himself on to the bed and rubbed his face happily on the comforter. He sighed contentedly and began removing the many blankets he had in the bags.

Izuku glanced over at Shouto, who was standing awkwardly at the door of the bedroom, “Shoucchan, come scent the blankets and bring the clothes.”

Shouto nodded, taking another few bags filled with worn clothes and sat down beside his lover, taking a blanket in hand and rubbing it against his neck and face. As Shouto was scenting the blankets, Izuku started taking out the clothing from the bags. The articles included pieces from himself, Shouto, and his mom.

“Do you really need stuff from your mom?” Shouto asked, not really wanting to have sex surrounded with Midoriya Inko’s scent.

Izuku blushed, “It makes me feel safe to have the scents of people I trust. If… if you don't want them here I guess they don't have to be in my nest, but, I mean, you probably won't notice it once my heat really gets going.”

Shouto shook his head, “It’s fine if it makes you feel safe. I just feel kind of awkward since we’ll be mating...around them.”

Izuku nodded, wrapping himself in one of the newly scented blankets, it was soft and comfortable but he felt a little too hot. Without really thinking about it, he made quick work of removing his clothes and adding them to his collection of clothing. Now naked, he snuggled back into the blanket and nearly purred at the contact of the soft blanket against his skin.

“I wash all the clothes twice after I'm done with them every time,” Izuku shrugged casually. “I've been doing it since my first heat.”

Shouto simply blinked, having a difficult time understanding Izuku's sudden stripping.

“What?” Izuku asked, sensing Shouto’s confusion.

“You're naked all of a sudden?”

Izuku blinked and glanced down at himself through his blanket, a deep blush spreading across his face. He flipped over and curled into a ball, Shouto could hear muffled rambling but he couldn't make out a word his mate was saying.

“Izuku, I can't hear you.”

Izuku slightly lifted his head, “I don't know… my brain’s all mushy and I always strip during my heat at home but I forgot… and I just did it without thinking and I'm so comfortable with you and I'm just so confused.”

Shouto snuggled up against Izuku's back, “Don't worry about it.” He tried to think of something to say to comfort him. “Shit, I'm not very good at this. Should I just strip too?”

Izuku nodded and in the next moment they were both naked and snuggled in a nest of blankets and clothing. The mix-haired boy rubbed his nose against the soft green curls of his mate.

~~

Izuku woke hours later, his breathes choppy and inconsistent. His skin felt like it was on fire and he whined. He tried to speak but it just came out as more whimpering. He could feel his cocklette throbbing between his legs but even worse was the aching in his hole. His entrance was pulsing slick and he just knew it was all wide and sloppy already.

Shouto roused from his sleep, sensing his mate’s distress and was taken aback by the sudden onslaught smell of Omega in heat. He immediately felt his cock harden in response and he could feel his mind become foggy, he mindlessly started grinding against Izuku's ass. His aching manhood slid easily along the shorter boy's crack with the copious slick that was pouring from Izuku's hole. Izuku thrashed and moaned, turning over onto his hands and knees. He arched his back presenting himself properly to Shouto.

Shouto growled, watching as his legs quivered and his hole twitched. It was gaping, and wet, and giving off the sweetest scent he had ever smelled. Completely on instinct, Shouto mounted his mate.

“Alpha...please,” was all Izuku could manage before Shouto pushed his cock into his sloppy hole. It felt incredible. It felt like the heat inside his body was finally soothed, but at the same time he felt like every nerve in his body was electrified. All he could do was scream and hold onto the comforter for dear life as Shouto set a brutal pace.

In the rare moments they managed to get enough time alone to have sex, it was always sweet. Shouto touched him like he was precious and perfect. Izuku loved how they slowly discovered each other's bodies, what made the other all hot and bothered.

This was not at all like that. It was animal and both boys were completely out of their minds with pleasure. Izuku could feel tears pouring from his face. With each slap of Shouto's balls against his ass cheeks, there was an obscene squelching noise from all the slick that was coming out of Izuku's body. Izuku couldn't tell if he was coming or not, everything was intense. He was shrieking and crying and couldn't formulate the words for what he wanted. But it didn't seem to matter since Shouto gave it to him anyway.

Shouto pounded into him with his large cock, wrecking him completely, and his hole was just taking it. His knot started to catch at the swollen rim and he slammed in one more time before locking inside. Shouto was pretty sure he had never come so much in his entire life. It just wasn't stopping. In the heat of the moment, Shouto leaned forward and bit into Izuku's scent gland. The smaller boy came, for what might've been the billionth time, he really didn't know. His channel drank up the copious amounts of cum. Distantly, in his post coital haze, Izuku acknowledged that his stomach had distended out slightly from the sheer amount of cum that was pumping into him.

They collapsed onto the bed,a heap of limp, dead weight. They were trying to control their breathing and collect their slowly clearing thoughts. Meanwhile, Shouto was beginning to become more and more concerned that he would never stop coming. Izuku's stomach had become so inflated from it that he feared the other boy would be in pain.

“I...it's not stopping,” Shouto said, hoarsely.

“Feel good,” Izuku hummed, rubbing his swollen tummy, his voice was barely a croak. “Like I've got pups.” It was really more of a slight bulge than anything else.

And if that didn't contribute to the next large spurt of cum that left Shouto, he didn't know what did. Izuku was obviously on birth control, but his rut induced brain craved to impregnate him anyway.

“Shit,” Shouto said. “One day, after we become top heroes, we’re gonna have a pup.”

“Or five,” Izuku giggled. “With this much cum I wouldn't be surprised.”

Shouto groaned. And finally the cum stopped, but they remained locked together.

“So…” Izuku trailed off.

“So.”

“We’re real mates now.”

There was a moment of silence and Izuku was suddenly washed over with an intense feeling of happiness. He looked over his shoulder, to see Shouto smiling. While Shouto's smiles were rare and precious, Izuku had definitely never seen this one before. It was so unguarded and innocent, and Izuku could feel tears filling his eyes at how perfect it was. If he was brought on this earth to make make that smile exist then he would do anything to protect it.

“I can feel you,” Izuku said, bringing his hand to his heart. “Here.”

Shouto nodded, “I can feel you, too.”

“I'd always heard that bonded True Mates have a special connection, but no one ever went into detail,” Izuku mused. “And I kinda get why now…”

“It would be pretty hard to explain,” Shouto agreed.

“Like, you're just… it's like I can feel your presence inside of me,” Izuku said, before blushing. “Not literally.”

Shouto nodded.

~~

They waited out the knot and eventually Shouto could pull out, much too Izuku's whining. His body felt so empty without Shouto nestled safely inside. He could feel cum already beginning to leak from his wrecked little hole and he brought his fingers down in an attempt to plug it up. He winced, as he was very sensitive at the moment, but he managed to push most of the cum back inside. It took three fingers to keep his gaping hole plugged enough to keep it all inside.

“We need to take a bath,” Shouto said. “So you don't have to plug it up. The nurses will come clean the bedding while we bathe.”

“I-its gonna get everywhere,” Izuku said. “There's so much.”

“It's fine, and we'll clean the rest out in the bath.”

Izuku nodded and removed his fingered from his swollen little hole. He could already feel the mix of cum and slick leaking out and dripping down his leg.

They made it to the bathroom, which was incredibly large. The bathtub was basically the size of a small pool, with all the jets and gadgets. They decided to remove the cum in the shower while the bath filled.

Izuku blushed, trying to press his legs together to keep more cum from dripping down his leg and onto the floor. Shouto adjusted the temperature on the bathtub before they stepped into the shower.

“Shouto, I'm not gonna be able to get it out myself,” Izuku blushed.

Shouto nodded, “Okay, um, lean against the wall, hips toward me.”

Izuku did as instructed, pushing his ass out to expose his messy hole, dripping with milky white cum. Shouto swallowed his breath before speaking again, “I'm gonna, uh, push it out with my fingers.”

Izuku nodded and Shouto tentatively thrust two fingers inside, causing the other boy to moan. He began pulling (what seemed like) endless cum from Izuku's body. He started to massage his stomach, which caused even more cum to spill out. Izuku was so turned on at this point but his cock was giving no indication of standing again. He could feel his his legs bowing and his body shivering. Shouto started to play with his prostate, brushing and pressing up against it as he cleaned out more cum. Izuku could feel himself coming but it wasn't from his front. His hole suddenly tensed and spewed a liquid similar to slick but slightly more watery. Izuku gasped as he felt an orgasm wrack through his body and he fell to his knees.

Shouto was totally shocked. He had heard the Omegas could squirt but he thought it was just some made up thing.

“Izuku, you're amazing.”

~~

They eventually got Izuku all cleaned out and settled into the bath together. The shorter boy was nestled in between Shouto's legs and he could feel the other boy's erection prodding his back.

“I can help you with that,” Izuku tried to say casually.

“No need,” Shouto replied, trying to relax. “Don't wanna get all worked up.”

Izuku nodded, “What if I just… keep it warm?”

“What do you mean?”

With a little courage, Izuku led Shouto's fingers to his empty hole.

Shouto rubbed at the sensitive rim, “I think I'd like that.”

The maneuvered each other so that Izuku was hovering over Shouto’s throbbing manhood. He slowly lowered himself down, moaning as he felt his sensitive hole being penetrated for the second time this day. Once he was completely nestled, he leaned back and tried not to wiggle too much. It just felt so good and soothing to be filled. It was like Shouto was just meant to be there.

He sighed contentedly and closed his eyes. The taller boy kissed his neck, where there mating mark was beginning to heal. It would soon leave a scar that would never fade from Izuku's skin.

They sat silently, enjoying each other's company and the warmth of the bath. They took their time washing each other’s hair and kissing sweetly in between conversation.

Shouto buried his face in Izuku's neck and mumbled something Izuku couldn't quite make out, though he had a pretty good idea based on the feelings he was getting off of Shouto.

“What was that?” Izuku turned his head to make eye contact with the other boy.

Shouto lifted his face and said with a look of pure adoration on his face, “I love you.”

They'd exchanged “I like yous” before and both boys were pretty sure that the other was feeling something much deeper. But this was the first time it was verbalized.

“I love you, too,” Izuku replied, immediately, no thought required.

Shouto smiled again, the same innocent smile he had shown earlier and Izuku knew that no other person would ever make him happier than Todoroki Shouto

Chapter Text

They were somewhere along the middle of Izuku's heat, and the boys already felt like they had had a lifetime of sex. Not that they were complaining. As it turns out, heat sex is pretty incredible. The stamina, the somehow never ending stream of slick and cum. Plus, the boys now felt like they knew every nook and cranny of each other's body. They were practically latched to one another constantly, so it would be pretty hard not to.

Even now, they were sitting in front of the television in the living room, Izuku warming Shouto's cock with his soft little hole. They were sitting kind of sideways, so Izuku could face Shouto while still watching the screen. At this point there wasn't even really anything sexual about it, Izuku just liked the comfort of having his Alpha fill him. It felt warm and safe, especially when Shouto snuggled him and whispered little compliments. A year ago, Izuku never would have thought Shouto would be the type, but he was slowly learned that Shouto was a really loving guy.

As they were watching the television, Shouto was feeding Izuku orange slices. He decided upon oranges in hopes that it would make Izuku extra happy and healthy for the remainder of his heat. And Izuku was just kind of cuddling up against Shouto’s chest, happy to be fed and pampered. He was also wearing one of Shouto's shirts, a big, soft sweater that was probably really expensive. It had slowly creeped up Izuku's pert little ass cheeks, causing the cold air to make him shiver. He groaned slightly, too lazy and comfortable to adjust the moved article of clothing. Shouto, sensing his distress, warmed his left hand up just enough to be toasty and brought it to Izuku's cold cheeks. Izuku sighed happily, snuggling even closer into Shouto’s chest as the older boy massaged his ass and thighs with a pleasantly warm hand. The stimulation didn't even cause Izuku's hole to clench, it simply stayed relaxed and warm, much like the rest of Izuku's body.

“We should've brought a blanket in here,” Shouto said, still massaging Izuku.

Izuku simply hummed in affirmation.

A minute later, a nurse came in to quietly hand Shouto a clean, unscented blanket. They did not even seem to acknowledge the boys’ state of undress nor their joined state. Quietly, they bowed and left.

Izuku blushed deeply, burying his face in Shouto’s neck and taking in that lovely, comforting scent. Shouto wrapped the blanket around the both of them.

“I'll never get used to that,” Izuku said. “Even if it's their job…”

Shouto nodded, “I never know what to say.”

Izuku giggled a little, of course Shouto would only be worried about the fact that he doesn't know what to say. Completely unfazed by the whole “walked in while we’re kind of naked and connected” part.

“I know I've said this before, but it always comes off so cool when you don't know what to say,” Izuku said.

“Is that a good thing?”

“It's definitely not a bad thing,” Izuku said. “But I know that truth.”

“What that?” Shouto asked.

“You, Todoroki Shouto, are a dork,” Izuku laughed and kissed his nose. “And you're really a sweet guy.”

Shouto could feel his face burning a little. If Izuku, the world’s sweetest person, thought he was a sweet guy, then he guessed he was doing alright.

“I'm just comfortable with you,” Shouto replied, honestly.

Izuku nodded, “That makes me happy.”

They sat in amicable silence, still eating the oranges.

“I don't really understand what the purpose of all this is,” Shouto said, motioning at the television.

“You mean the TV?” Izuku asked.

Shouto nodded.

“What… what don't you understand?”

Shouto shrugged, “Why do people like it?”

Izuku blinked, “I don't know, I guess people like a break from the real world.”

“But the real world’s pretty great,” Shouto said, seriously, looking straight into Izuku's eyes.

And if that didn't make Izuku's heart sing, he didn't know what did. He could already feel the tears coming when they were interrupted by a call on Izuku's phone.

Izuku grabbed it from the arm rest, the screen read “Mom”. He quickly tried to collect himself as he slid the “accept” button.

“H-hello?” Izuku said.

“Izuku? Hi, honey,” Inko said. “I'm just calling to see how you're doing. I know I called yesterday, but you know how I get.”

Izuku smiled, “Yeah, Mom, I'm good.” He glanced at Shouto, who was just sort of watching him. “Really good.”

“That's wonderful,” She sounded like she was starting to get choked up. “I'm just so happy you've met such a nice Alpha. He just really seems to love and respect you.”

The tears from earlier started to come back up, “Mom…”

“Just know that I'm really proud of you,” She said. “And you can always call me if you need anything.”

“I know, Mom,” Izuku sniffled. “Are you feeling okay?”

“Of course!” She sounded a little more chipper. “I just got to thinking about how much you've grown up, and now you're mated… you're not a little boy anymore.”

Izuku's tears were definitely pouring at this point, “Oh, Mom… thank you. He makes me really happy.”

Shouto smiled ever so slightly and tightened his grip around his mate. He couldn't hear what she was saying, but he got the gist. He used his thumbs to brush away some of Izuku's tears.

“And… I've been thinking,” Inko said. “Since the two of you have officially bonded, would Todoroki like to stay at our home?”

Izuku was totally shocked, “R-really?”

“Yes,” Inko replied. “You can't be separated anymore and I would really like you to stay with me… even just for a little while.”

A huge grin spread over Izuku's face, “Of course! I'll have to talk to Shouto but that would be great!”

Izuku was already getting pretty pumped up. This would be the perfect way to get Endeavor as far away from his mate as possible. He had already been planning way to get Shouto out of that house but this made it even easier.

“Okay, honey, you can talk it over,” Inko said, happily. “I love you!”

“Love you, too!”

“I'll call tomorrrow. Give Todoroki a big hug for me!”

“Okay, bye-bye!”

They hung up and Izuku smiled up at Shouto.

“Your mom really loves you,” Shouto said, a little wistfully.

Izuku nodded, “She really loves you, too. Every time I call she says how happy she is I met you.”

Shouto smiled, and brushed a few curls from Izuku's forehead. However, after feeling the softness of the strands, he couldn't help but start playing with Izuku's hair. Izuku leaned into the touch, he loved it when Shouto played with his curls. He always made sure to massage his scalp and it felt so good.

“My mom wants you to live with us,” Izuku said.

Shouto's hands stilled in his hair, “She does?” His voice was honestly so surprised.

Izuku nodded, “Is it so surprising? We have to live together now and she wants us to live to live with her.”

Shouto sighed, “I… I don't think my dad is going to approve.”

Shouto realized that he hadn't thought about their living situation after this. Bonded Mates had to live together for their health. He really didn't want Izuku living with his dad. If Endeavor laid so much as a finger on Izuku he couldn't promise what the repercussions would be.

Izuku shook his head, “It’s not up to him, he already agreed to our mating.”

“Yeah, but…”

Shouto was really conflicted. He knew Endeavor wouldn't be happy if he moved in with Izuku. Shouto was afraid that he would try to harm Izuku or his mom. But if they stayed at his own house, he was worried about what Endeavor might do to Izuku there. Endeavor had a temper and he already didn't like Shouto's mate.

Izuku brushed his fingertip against Shouto's cheek, “Shoucchan, let me in.”

Shouto blinked, and sighed, “I'm worried that he'll hurt you, or your mom… but I also don't want him near you at all.”

Izuku thought for a moment, “We should call your sister, she might know what to do.”

Shouto nodded and took out his own phone, tapping on his sisters name. It began to ring, and Shouto started to brush his finger along Izuku's jawline, nervously.

“Hello?” Fuyumi answered. “Shouto?”

“‘Hi.”

“Is something wrong?” Fuyumi asked, worriedly.

“Uh… not quite,” Shouto replied. “I've got a question about dad.”

There was a pause on the other end, “Yes?”

“I… I want to live with Izuku,” Shouto said. “At his home.”

“Ah, I see,” Fuyumi said. “... Do it.”

“Really?”

“Yeah, just… what's he gonna do?” Fuyumi said. “If you're worried about him hurting your mate, he's not a total idiot. He knows Midoriya is going to make you stronger.”

“Yeah, but his mom…”

“Will be fine,” Fuyumi said. “What's he going to do? Track her down?”

“Well…”

“Look, don't worry so much about it,” Fuyumi said.
“He's been bragging to people about how powerful you're going to be with Midoriya around. He even says the whole thing was his idea.”

Shouto rolled his eyes, that really figured.

“So, it really shouldn't be a problem,” Fuyumi continued. “Just convince him it'll help your powers in some way.”

Shouto sighed, “Yeah, okay.”

“Anyway… have you been taking care of Izuku properly?” Fuyumi asked. “He needs a lot of food and water to keep up his stamina and he needs a prostate milking at least twice during his heat.”

“Prostate… milking?”

Shouto could feel feel Izuku still in his arms and he glanced down to see a clearly uncomfortable Izuku. He almost told his sister that he needed to go, but before he could say anything, his sister was already speaking again.

“Shouto, please tell me you know what that is.”

“I know what milking is…”

There was a long sigh on the other end of the phone, “He clearly doesn't want you to do it but you need to convince him. Male Omegas can get really sick.”

Shouto could feel his chest seize, “Sick? What… what even is it?”

“Yeah, male Omegas can get really pent up during their heats… I don't really want to explain how to do it,” Fuyumi said. “Just ask him.”

“I guess…”

“Anyway, I have to go. Take care of him, Shouto.”

They said goodbye and hung up.

Shouto looked at Izuku again, who appeared to be attempting to disappear on his lap. Maybe he thought that if he didn't move, Shouto wouldn't see him.

“Izuku…”

No reply.

“Izuku,” Shouto said, soothingly, rubbing Izuku back.

The other boy slowly lifted his gaze to meet his Alpha’s, his face bright red. He bit his lip.

“Why didn't you tell me you needed that?” Shouto asked. “You know I don't know a lot about...this kind of stuff.”

Izuku sighed, “Because...I didn't want to do it.”

Shouto waited patiently for him to explain.

“I don't like it. It-it gets me all worked up… and then there's no completion… that's not even the bad part...when it's over my body gets all… all limp, and I can't move for myself! And it's so frustrating, and embarrassing, and…”

Shouto kissed him on the head, “I don't really understand what you mean.”

“It… okay, so it… it's like, stuff comes out, but there's no climax. It feels good at first but then the ending isn't satisfying. So it's just really frustrating. But then when it's all done, my body gets all relaxed and I can't move at all. It's like I'm made out of putty and it's horrible.”

Shouto nodded, he still didn't completely understand but he thought he got the gist, “But you have to do it?”

Izuku sighed and nodded, “My tummy has started hurting a little so I knew I needed to, but…”

Shouto took one of Izuku's hands in his and squeezed it, “If you're hurting, Izuku, we need to do it. I promise, I won't let anything happen to you. So, please rely on me.”

Shouto kind of felt like a shitty Alpha. How could he not notice that his mate was in pain?

Izuku felt tears springing up and he gave his mate a wobbly smile. Shouto felt a sense of trust wash over him and he knew it was coming from Izuku.

“Let me help you,” Shouto said, seriously. It was more of a question but it was firm.

Izuku nodded, and started to lift himself up, his hole clenching down as Shouto's cock left his body. The mix-haired boy helped him up until Izuku was completely empty. Izuku grimaced at the emptiness, he had become accustomed to being constantly filled.

Izuku backed up a little and laid down on his back, he then lifted his legs into his own arms, exposing his hole. The puffy, red entrance was winking, begging to be filled again.

“What...what do I do?”

“You've gotta find my prostate and then just rub, like a massage,” Izuku said. “It'll take a while, but I'll leak, here.” He brushed a hand over his flaccid cock. “And here.” He brought his hand down to brush against his winking hole.

“Until you come?”

“No, it's not exactly cum, but… anyway, I'm going to go all limp but I'll be able to talk a little.”

“Oh, okay…” Shouto said. “Ready?”

“Yeah.”

Shouto moved forward and positioned himself close to Izuku's rear. He brought two fingers to the little hole and rubbed along the rim, prompting some slick to leak from the swollen entrance. He coated his fingers, using the slick as lubricant before pressing his fingers forward. Izuku's hole easily accepted the digits, sucking them in like they belonged there. Shouto had become so familiar with Izuku's body that it took very little searching to find the little bundle of nerves inside his lover.

Shouto began rubbing at the little nub inside his body. He could feel how tense Izuku was about the whole thing, but he didn't really know how to comfort the other boy to make him relax. So he opted to send loving and comforting emotions toward his mate, hoping that that might reach him.

And it did, Izuku felt a sense of love and protectiveness from Shouto. He knew that his Alpha would take care of him, but now he could feel it. He felt his own body become relaxed, and he started to really enjoy the sensations of being touched by his lover. He decided to just give himself to Shouto, realizing that he was willing to submit to his Alpha like this.

Shouto continued to work his prostate, and Izuku could hear some strange, hum coming from somewhere in the room. His mate continued to tweak and press at his nerves, and the hum became more of a pitched moan. It was then that Izuku realized the noise was coming from his own mouth.

Shouto would be lying if he said this wasn't ridiculously hot. Izuku had become so pliant and open as he manipulated the little bundle of nerves. Of course he had used Izuku's prostate to bring him to orgasm before, but not with this level of persistence. He was initially concerned by Izuku's complete aversion to it but now he was no longer sensing any anxiety or fear from the other boy. Izuku was all relaxed and comfortable Omega right now. And he could tell the the other boy was feeling good, despite the fact that his cocklette was still lying flaccid between his legs. And it was truly a vision, how Izuku was getting all red and sweaty, while his member remained all sweet and soft.

Izuku couldn't tell why this felt so different from usual. Maybe it was Shouto's Alpha pheromones or just the fact that the other boy was a comforting presence in general.

It took several minutes of prodding and massaging, but eventually Izuku reached some semblance of an orgasm. But it really wasn't an orgasm, it was more like his cock began leaking a little fluid and his ass leaked slick simultaneously. With a sigh, Izuku’s body began to grow more and more limp until he was lying heavily on the couch.

“I-Izuku?” Shouto said, concerned. He knew Izuku said he would get limp, but he literally wasn't moving aside from some really slow blinking.

“Yeh,” Izuku replied, his lips barely moving.

“I'm going to take you to bed, okay?” Shouto figured it would be easier to arrange the the pillows and blankets in such a way that Izuku could sit up.

“Yeh,” Was all Izuku replied, obviously finding it difficult to speak.

Carefully, so carefully, Shouto lifted Izuku into his arms. He made sure to use the crook of one of his arms to support Izuku's head. He was all dead weight, he was like a ragdoll. How could someone so tiny be so heavy? Admittedly, Izuku did have some muscle, but this was like carrying a ton of bricks. Luckily, Shouto himself was a strong guy and could carry Izuku with relative ease.

He eventually got Izuku all settled onto the bed, propped up by plush pillows and surrounded by the comforting scents of his loved ones.

Shouto decided to entertain Izuku during his lax state by doing little things with his ice and fire. He usually didn't use his powers frivolously but he liked seeing the corners of Izuku's mouth turning up ever so slightly.

The whole “relaxed state” thing didn't last more than 10 minutes, but Shouto spent all 10 minutes taking care of Izuku diligently. Shouto couldn't tell, but Izuku really wanted to giggle at how how sweet it was. The Alpha had the sweetest expression on his face as he tried to entertain his mate. He was like a little kid taking care of a sick relative and Izuku felt so loved.

When Izuku gained full control of the muscles in his face, the first thing he said was “I love you, Shoucchan.”

Shouto looked up from making a little ice All Might figure and sighed, clearly relieved, “I really love you, Izuku.”

Izuku laughed, “‘Really’.”

Shouto didn't seem to get that Izuku was making fun of him and continued seriously, “I was so worried.”

That sobered up Izuku pretty quickly, “Yeah, it's usually scary, but I shouldn't have been so worried about it. You made me feel so safe that I wasn't even scared like usual. I don't like having no control over my body, but it felt like you would never let anything happen to me.”

“Of course,” Shouto said, his words so firm and secure. “We’re always going to protect each other.”

Izuku felt so warm at the idea and he was so touched that Shouto said they would have each other's backs. Not just Shouto protecting Izuku. It said so much about Shouto's respect for Izuku.

Shouto laid down next his mate, “What normally happens?”

“When I'm milked?” Izuku asked. “When I had my first few heats my mom would have my doctor do it with a massager and then my mom would take care of me after. And since then I've been on suppressants and my heats were much milder, so I didn't need milking. It felt totally different back then. You made me feel so safe and loved but with a doctor it was so… impersonal.”

“I should hope so,” Shouto said, it came out flat but Izuku knew he was joking.

Izuku rolled his eyes, “And when my mom took care of me after… it wasn't that she didn't make me feel safe, I knew she wanted to make me happy, but I don't know. I was still always scared about the lack of control I had… I guess it's just different when I'm with my Alpha.”

Shouto felt a surge of happiness at Izuku acknowledging that he was his Alpha. The deep, more animalistic part of his mind completely smitten with the adorable Omega before him. The taller boy wrapped his arms around his mate and Izuku snuggled closer.

Shouto’s body relaxed in his lover's embrace, Izuku's strong arms wrapped around his torso. He felt just as safe in Izuku's arms as Izuku felt in his. And there was something profoundly special about that.

They ended up napping until another wave of Izuku's heat hit.

~~~
Writer’s cut:
Okay, so I wanted this scene really bad, but it just wouldn't fit appropriately in this chapter, so here's a little extra spice from some point in Izuku's heat.

Izuku was having trouble sleeping. He just couldn't stop that little dull ache in his hole, no matter what his did. He even asked Shouto to keep him filled when they slept but even that wasn't enough. It certainly helped, but it just wasn't enough. His body wanted friction, it wanted to be ravished constantly.

It wasn't like the ache was horrible or painful, but it was annoying, and so obvious when he was trying to sleep. Because nothing could distract him from that ache when he was trying to sleep. He could only get in an hour or so before the aching got to be too much. He thought about saying nothing, he knew Shouto was trying to help him, but he was starting to get really tired.

However before he could say anything about it, Shouto brought it up himself, “I know you've been having trouble getting good sleep, so I've been trying to think of a way to help you.”

Izuku was surprised, but he should have known that Shouto would take notice. He had been so attentive.

“And I realized,” Shouto continued. “That we could use one of those machines to lull you to sleep. We’ll just put it on a low setting so it won’t stir you too much.”

“Machines?”

“The sex machines? The ones with the toys attached? I read about them in the pamphlet for this hotel. You can ask them to bring one in with a new toy attached.”

Shouto was getting a little animated, he was clearly excited about figuring out a way to help Izuku.

“I...I guess it wouldn't hurt to try?” Izuku blushed.

~~

So, here they were, a fucking machine lying on their bed. The machines used to be quite large but they had become far more compact in recent years.

Shouto yawned, he was so sleepy, so he could only imagine how tired Izuku was. The younger boy already had darkish blue circles contrasting his dusting of cute freckles.

They got comfortable, Izuku lying partially on top of his mate. His ass was just enough away from Shouto that the machine would have enough room to fit.

Izuku was a little nervous but also excited. When he gave Shouto the ‘okay’ the older boy slowly inserted the toy into Izuku's hole. His entrance was still loose from heat and his last wave, a little slick started to flow from the penetration. Izuku moaned but was glad that he didn't get hard. The toy was very similar in size to Shouto but he wished there was just a little more girth to match his mate’s. Plus, that delicious mixture of both hot and cold that Shouto's body always seemed to give off… No toy would ever truly compare to his lover, though he might not mind a model of his mate's cock for personal use…

His train of thought was interrupted as Shouto turned the machine on. The toy slowly started moving inside him, a gentle rocking inside him. It was surprising soothing. The dull ache dissipated. Shouto adjusted the machine so that it would not be brushing against his prostate. So instead of arousing him, Izuku's hole was fed just enough to keep it satisfied. It was making little noises from the slick leaving his body, but Izuku didn't even care. He just settled in more against Shouto’s side, letting his body relax.

Shouto was always a quick and easy sleeper, so when he was sure Izuku was settled and happy, he quickly fell asleep. Izuku was lulled to sleep as well as his hole received the friction it had been craving.

Chapter Text

The rest of Izuku's heat passed smoothly, both boys were pretty sure they wouldn't be interested in sex for a while. Shouto's dick literally felt raw and the very idea of getting hard made him grimace. Izuku wasn't faring much better if his wincing after sitting meant anything. His doctor recommended that they apply ointment to help him heal.

They also managed to convince Endeavor to allow them to live together. With a little suggesting and promises to become the best, Endeavor gave in pretty easily.

Inko was excited to have her son-in-law living with her. She was just so elated that Izuku had found someone that respected him and his wishes. All she ever wanted was Izuku's happiness. She had been afraid that Izuku's passion for heroes would make it difficult for him to find a mate. Omega heroes were practically unheard of. So, she was happy to see that he had found an Alpha who not only respected his dreams, but supported them.

Of course, she would have been fine if Izuku had never taken a mate, but she had always hoped Izuku would seek the companionship and support of one.

Izuku playfully tapped Shouto's ass with his foot and the other boy rolled his eyes. They liked to touch each other for no apparent reason, just enjoying the comfort of touch. Izuku and Shouto were carrying in his boxes of clothing and other miscellaneous items. Shouto really didn't have much in terms of personal possessions, so it wasn't much to carry. Even with the bags of clothes from Izuku's nest.

Izuku used some strength to switch the boxes to one hand, so he could knock on the door. He heard his mom yell (well, kind of yell), “Coming!” Followed by footsteps. The locks of the door clicked and the door swung open. Inko stood on the other side of the door, smiling happily at the two boys.

“Oh, boys, I'm just so happy for you,” Inko said. This was the first time seeing her son since he bonded with Shouto. There was a new glow about him, something beautiful and happy.

“Mom…” Izuku said, smiling back. He and Shouto stepped into the house.

“Thank you very much for having me, Mrs. Midoriya,” Shouto said, bowing to the best of his abilities with the boxes in his arms.

Inko laughed good naturedly, “No need to be so polite, we’re family now! Call me Inko.”

Shouto felt his cheeks heat up, “Thank you, Ms. Inko.”

“Well… good enough,” Inko said, she was going to get him to relax one day.

The minute the boxes were down, Izuku was enveloped in a hug. Under normal circumstances, he would be embarrassed to be hugged by his mom in front of people but these weren't normal circumstances. He hadn't seen her in a week, and the Omega inside him still craved the comfort of his family. And Shouto was his Alpha so he wasn't necessarily ‘people’. He purred ever so slightly as she scented him, not overpowering the smell of Shouto's scenting. It was a familiar scent, one that alerted others that he was cared for by others.

Shouto watched the scene with a wistful smile, he hadn't had anything like that with his family in a long time. Endeavor never scented him, not that he was at all interested, and his mom hadn't scented him since the “incident”. She always looked like she wanted to, but she likely wasn't able to forgive herself fully. As for his siblings...they had kind of been put off of that kind of behavior on account of Endeavor.

So, when he was pulled into the hug by both Izuku and Inko, he was more than a little surprised. He felt a little awkward at first, Izuku was small but Inko was tiny. Shouto bent his back, returning the hug the best he could. Shouto loved touches from his mate as it was a reminder of their special bond and love, but Inko’s hug was different. She didn't have much of a scent, as she was a Beta, but it was warm and comforting all the same. Like a mother. It was then that she scented him too, officially claiming him as a member of the family.

Shouto could feel his eyes becoming a little misty but neither Izuku nor Inko made any mention of it. When they separated, Izuku squeezed Shouto's shoulder reassuringly. Shouto smiled, that sweet, delicate smile.

Inko clapped her hands together happily, “Welcome to the family! I'll let you boys unpack while I cook dinner!”

“Do you need any help?” Shouto asked.

Inko shook her head, “Thank you but it would be better if you work on unpacking.” She smiled ruffling his hair.

~~

Shouto was pretty surprised when he saw Izuku's room, but he really should have expected it. All Might paraphernalia from ceiling to floor. He could feel embarrassment from Izuku, so he didn't want to upset his mate by cracking a joke about it.

“I know it's a little obsessive but I've always looked up to him,” Izuku gestured at the All Might posters and figurines. “And the stuff just kind of collected over time. Now I'm so used to it that I don't think I could sleep without it. Then again… I guess I did fine during my heat but that's kind of different. My head’s in a different place during my heat. Uh, you probably think I'm so weird and regret mating with me.”

Shouto blinked, registering all of Izuku's rambling, “I'm not judging, I like All Might, too and I'm not going to suddenly stop wanting to be your mate. Besides, I can't sleep without tatami flooring.”

Izuku frowned at his carpet, “Well, you can do whatever you need to to get comfortable. This is your home, too.”

Shouto smiled and thought for a minute as he stared at all the posters, “So… what really is your relationship with All Might?”

Izuku opened his mouth to lie, but he realized that he really didn't want to. Shouto was his mate, and he didn't want any secrets between him and his mate.

“I'll tell you… but I have to talk to All Might first,” Izuku said, seriously. “And it's not that I don't trust you. It's just not completely my place to tell you. But I want to. Tell you, that is.”

Shouto nodded. He could tell his mate was struggling with not telling him. He felt better knowing that Izuku didn't want to keep it from him.

~~

In about an hour the room was completely revamped. Izuku was practically awestruck as he watched Shouto work. He tried helping, but the other boy was so quick in his determination that it was hard to keep up.

Next thing he knew, his room was completely Japanese. Tatami flooring and the whole rigmarole. Shouto was careful to keep all of Izuku's All Might stuff where it was, so the room was a strange combination of traditional Japanese and All Might fanboy.

Izuku was pretty impressed with his mate, “You worked hard, Shoucchan.”

Shouto nodded and said, “I tried my best.”

Izuku laughed and pecked him on the lips. Shouto was so cute.

“Boys! Time for dinner!”

~~

Once dinner was over (and Shouto helped wash the dishes after insisting) they found themselves alone in their room again. Shouto didn't know how incredible it would feel to live with his mate. Even getting ready for bed felt amazing. Brushing their teeth next to each other and watching the Omega get into his pajamas. All of it was amazing.

He wrapped his arms around the smaller boy as they settled into the bed. It was a lot smaller than the one at the Heat Hotel but they snuggled anyway so it didn't matter. All that mattered was the the warmth and scent of their mate. Izuku giggled and planted a big kiss on Shouto's lips. The taller boy smiled and kissed him back, enjoying the feeling of Izuku's soft lips pressed against his own.

The kiss deepened, and Izuku's tricky little hands started to creep up Shouto's shirt. Shouto really wanted to continue but he was actually pretty exhausted.

“Izuku,” Shouto said, separating their lips. “I really want to continue… like really really bad, but I think our bodies need to rest. Plus… I'm sleepy.”

Izuku watched as his Alpha’s eyes drooped, clearly struggling to stay open.

“We don't have to continue if you don't feel like it, Shoucchan,” Izuku said. He had to admit that his hole was also pretty sore from their week long activities, and he didn't want Shouto to feel pressured.

Shouto nodded, and whispered, “Thank you.” His eyes already starting to close.

“You don't have to thank me,” Izuku whispered back. “I'm your mate.” Shouto's eyes closed completely and he quickly fell asleep. Izuku kissed him on the forehead before snuggling into the bigger boy's chest.

~~

The next morning their alarm went off and they woke groggily. It had been awhile since they had gotten into the swing of getting ready for school. Shouto groaned, realizing that he had gotten out of the habit of working out early in the morning. It was just so hard to get up when he opened his eyes and saw his warm, sleeping Omega curled up on his chest.

They got up and slowly got ready, helping each other get their things together. Izuku struggled with his tie as usual and Shouto batted his hands away.

“I've been wanting to do this forever,” Shouto said, coming around Izuku's back bringing his hands to the already messed up tie.

“Do my tie skills bother you, Shoucchan?” Izuku teased, watching as his Alpha looped the knot, ensuring that it wasn't too tight around his neck.

“Immensely,” Shouto replied, a little smirk on his face.

Izuku turned around, poking at the little smirk with his index, “Want me to tie yours, Mr. Big-Alpha?” He tried grabbing for the tie and Shout quickly swerved out of the way.

“No, thank you,” Shouto quickly left the room for breakfast as he tied his own toy. Izuku chased after him, throwing his arms around the boy’s neck so he could be dragged.

~~

Izuku found himself in All Might's office later that day. He was a little nervous, not sure how All Might would react. He hoped that his idol would accept his request.

“What do you need to tell me?” All Might asked, sitting in front of him. “Did something happen?” There was worry in his voice.

“Well, Shouto, uh… I don't know how to say this,” Izuku shifted in his seat nervously.

All Might look even more concerned, “Did Todoroki touch you without your permission?” He asked, gravely.

Izuku practically shot off the couch, “No, no, no, no, it's not like that at at all!”

“I understand that feelings and such can become very confused during the first shared heat, but you can talk to me about anything,” All Might said, trying to be reassuring.

“No! Shouto would never… I liked his touches! Very much!” Izuku exclaimed.

They both blushed deeply at the confession but All Might relaxed.

“I apologize,” All Might said. “I had just read an article on how Omegas are sometimes taken advantage of during their heats. I know Todoroki is a good kid, but I was afraid…”

“Yeah, that’s… we’re all good there,” Izuku said. “I wanted to talk about something else.”

“Yes, go on,” All Might was a little embarrassed by his sudden outburst. He absolutely believed that Shouto was a good egg, much like all of his students, but he couldn't help but worry. When they're so young, Alphas can get all delirious on heat hormones.

“I… I don't like keeping secrets from Shouto,” Izuku shrugged.

“Yes, trust is important in every relationship,” All Might agreed.

Izuku realized that All Might didn't understand what he meant by the silence that followed afterward.

“I want to tell Shouto about One for All,” Izuku clarified.

All Might's eyes widened, “Ah, I see.”

There was another long pause, the larger man was clearly thinking.

“Todoroki is your True Mate,” All Might said. “I think he's a trustworthy boy and I would never ask you to keep keep something so important from him.”

“Really?”

“Yes.”

Izuku sprang from his seat and launched himself into All Might's arms.

“Thank you so much,” Izuku said. “Shouto won't tell anyone, I promise.”

All Might laughed and returned the hug, patting the Omega on the back.

~~

At lunch Izuku sat with Shouto and friends. They had already been given the gist of what happened last week. Both boys felt like they had so much school to catch up on. It was driving Izuku a little crazy, thinking about the week of class he missed out on.

“Oh, Deku, you would have loved the activity we did on Wednesday…” Ochaco was saying.

Tenya agreed pointing at a place in his notes that Izuku should focus on.

Denki came up to their table, a big grin on his face.

“We’re going to the hot spring and you're all invited!” Denki said, pointing at everyone at the table.

“Who is ‘we’,” Tenya asked.

“The whole class!” Denki exclaimed. “Are you in?”

Ochaco agreed, gladly and Tenya said he would have to check his schedule (which really just meant yes). Izuku and Shouto glanced at each other.

With their silent agreement, Izuku said, “We’ll go!”

~~

Later that night, Izuku told Shouto everything, from growing up quirkless to being given One for All. Shouto listened carefully, never interrupting as Izuku explained his journey.

When he finished Shouto nodded, “So, definitely not All Might's love child.”

Izuku laughed, “No, definitely not.”

Of course, Shouto agreed to keep Izuku and All Might's secret. Even if Izuku wasn't his mate, there would be really no point in him spreading it around. Shouto was more of a listener than a talker and he liked to think that he was a good secret keeper (let’s face it, he’ll take this secret to the grave if it makes Izuku happy).

~~

A week later the mates were headed toward the hot springs. Everyone took the bus, much to the chagrin of the other passengers inside as they watched a large group of U.A. students approaching.

Izuku and Shouto sat next to each other and Shouto almost immediately fell asleep on Izuku's shoulder. The other students were pretty surprised at how sweet Shouto was with Izuku.

“He's like a kitten,” Mina whispered, trying not to giggle. She was craning over two rows of seats to see.

Tenya whispered, loudly, “Sit in your seat properly!” He motioned to all the students that were watching Shouto like a zoo animal.

Izuku brushed some hair from Shouto's face, “There's no point whispering if you’re just gonna yell at the same time.”

Tenya readjusted his glasses, “I apologize.”

“It's okay, he's a pretty deep sleeper anyway,” Izuku said, fondly. He agreed that his mate was really cute when he slept. Well, he was always cute, but especially when he was sleeping!

Ochaco’s eyes were huge, like she was looking at a really cute animal, “Please, Deku, can I pet him?” Some of the other girls in class perked up. They started arguing about who got to pet Shouto.

“None of you get to pet him!” Izuku tried to exclaim quietly. “He's not a pet!”

Shouto sighed, they woke him up a while ago but he hoped if he stayed asleep they would leave him alone, “Yeah, I would prefer if you didn't.”

Izuku looked down at him apologetically, “I'm sorry, Shouto.”

“Not your fault.”

The girls quieted down after that. They felt bad that they had woken their classmate up.

Shouto could finally get some proper shut eye.

~~

When they finally arrived at the hot springs, the crowd of teenagers hooted and hollered, practically leaping out of the vehicle. They may have heard a random elderly woman mutter “good riddance” as they were leaving. Maybe it was the wind. Who knew?

Anyway, they all ran in, eager to let their sore muscles relax in the hot water after being stuck in a car. The front desk didn't even see what hit them, when the boundless energy of high school students came in. They had decided on four to a room (except for Izuku and Shouto who opted for a private room).

The classroom of 20 lined up at the counter and asked a billion questions along the way.

“How are the springs separated? By gender? Secondary gender?”

“Are yukata provided?”

“What about meals?”

When they quieted down, the woman at the front desk replied, “They're separated by gender; yes; yes.”

The students nodded. Only to ask several more questions.

~~

They were in the water almost immediately. Izuku had never been to a hot spring with friends before and now he was here with his mate. Shouto was really handsome, too, with the cloth slung around his hips. Izuku was sitting in the water, letting the heat soak through his bones. Shouto was just dipping his his feet at that moment.

Izuku loved his calves, and his abs, and his face, and--his eyes zeroed in on the large bulge between his mate’s legs. He loved Shouto's cock so much. All the toys he used in the past and nothing compared to how Shouto's cock fucked him. His mate scraped on just the right placed with just the right amount of pressure when he needed it.

Izuku was practically salivating as he ogled his mate. Which Shouto noticed, raising an eyebrow as his mate’s sweet “I'm-turned-on” smell wafted in his direction. Just as he was about to say something, Kirishima splashed Izuku with the warm water.

“You fucking horn dog!” Kirishima laughed, pointing at Izuku. “Give your Alpha the fuck-me eyes in private, not here.”

Izuku blushed, covering his face with his hands. He was totally caught red-handed while checking out his Alpha. He guessed it could be worse, it was a good thing Shouto was his Alpha. Not that he really looked at other Alphas, Shouto was basically the hottest person he had ever met.

As he was trying not to melt into an embarrassed puddle, there was another conflict not too far away involving Mineta and Tenya. Mineta wanted to go full peeping tom and Tenya was having none of that.

It ended with Mineta falling on his ass.

~~

After having a lot of fun with their classmates, Izuku and Shouto retired to their room. Izuku had a yukata haphazardly slung on his body, the top of which was slipping down his freckled shoulder. The exposure resulted in the tantalizing view of the slope of Izuku's neck. Shouto's bite stood out and he leaned down to kiss it as he closed the door to their room. Izuku smiled and leaned into the touch.

“We have a private hot spring,” Shouto said into the freckled skin.

“Really?” Izuku asked like an excitable puppy.

Shouto laughed, “Yup,” He pointed at the door leading toward it.

Izuku’s eyes twinkled a little mischievously and he stepped away from his mate. As he walked toward the door, he allowed the yukata to fall all the way down his shoulders and back. Shouto watched, awestruck, as the fabric continued to fall down his mate's expanse of freckled skin. It caught slightly at Izuku pert rump, but with a saucy wiggle, it fell all the way to the floor. The Omega winked at his Alpha as he opened the door and disappeared behind it.

Shouto blinked, what even just happened? Was he just seduced? It certainly worked if the tent in the front of his yukata meant anything. God, Izuku was full of so many surprises.

Like a man in a trance, Shouto stripped and followed Izuku outside. He discovered the Omega already soaking in the water. And he was bright red, like a tomato. He tried covering his face when Shouto entered.

Shouto sighed happily, “Thank God, I thought you turned into some kind of sex demon.” He settled into the water, pulling Izuku toward him.

“Sex demon?” Izuku giggled, climbing into Shouto's lap.

“Yeah, here to steal my in innocence,” Shouto said, seriously.

Izuku stared at him for a long moment before laughing hysterically. Tears literally started streaming down his face, he laughed that hard. Shouto's face remained completely serious.

“S-steal your innocence,” Izuku tried to brush his tears away to no avail.

“There's nothing funny about demons,” Shouto said, gravely. His face had been a mask up until then, but the corner of his lip started twitching.

Izuku lightly slapped his shoulder, “You idiot,” He pressed his lips to Shouto's and he could feel the other boy's smile pressed against his own.

Ugh, Izuku had been so fucking horny since creeping on his mate earlier, okay? Like really really horny. And they hadn't done more than jerking each other off all week. Izuku's hole was aching. He could feel it twitch as he started to get wet.

“Your smell…” Shouto said, unsure how to describe just how decadent the other boy’s scent was.

“You too,” Izuku said, burying his face in his mate’s scent gland.

Shouto's hands slid down to Izuku's hips. Unconsciously, the smaller boy started to grind down on Shouto’s crotch, brushing their cocks together. They both moaned and Shouto gripped Izuku's hips tighter. Izuku took this as a sign to continue grinding. His entrance was starting to leak slick now, and a distant part of his mind wondered if he was dirtying the water.

Shouto kissed along Izuku's chest to his nipples. He brought one into his mouth, nipping and licking until the nub turned dark red. Izuku gripped at the silky strands of Shouto's hair for leverage.

Shouto wondered what Izuku would look like when he becomes pregnant. His chest would swell slightly with milk, and his belly round with Shouto's child. He was going to be so fucking beautiful (not that he wasn't already). He knew it wouldn't be for a while but he felt his chest seize with protectiveness. It also made him really turned on.

“Izuku…” Shouto groaned. “I can't wait to fill you with babies.”

Izuku blushed deeply, “Are you saying embarrassing stuff on purpose?” He moaned again as Shouto fingers brushed against his hole.

“I didn't mean to embarrass you,” Shouto said. “I just genuinely want to have children with you.” He pressed a finger into that slick hole, maneuvering it around before adding a second.

“M-me too, but… not now,” Izuku said, in between choked gasps. He wanted Shouto's babies, he wanted them so bad. But he wanted to work on school and their classmates careers first.

“Not now,” Shouto agreed, scissoring his fingers. He added a third finger and then a fourth, being sure to stretch and prepare his mate in between.

Izuku always started to mumble incoherent thoughts around this point in their lovemaking but one thing came out clear, “Water’s… gonna get inside,” he moaned pathetically.

“Is water getting inside?” Shouto asked. “Do you want to move?” He liked how easy is was to maneuver in the water, but he was fine with moving to someplace else if Izuku wished it.

Izuku shook his head, his wet curls dripping a little, “Kind of like it. S’warm,” he nipped at Shouto's lips. “Ready.”

Shouto removed his fingers and Izuku grunted. He felt the head of his Alpha’s cock pressing against his entrance. His body quickly accepted the hard member inside, and they both groaned when Izuku sank to the base of Shouto's dick. It felt like an eternity since the last time Shouto was inside him, and his hole eagerly clamped down a little.

Shouto cursed, resting his forehead on Izuku's shoulder as he slowly began to move his hips. Izuku moaned, beginning to move his hips as well. They slowly built up a rhythm that worked for the both of them. Shouto began to thrust hard and fast into his lover, the both of them needing something passionate after a week of non-penetrative sex.

It was so hot, so fucking hot. Their bodies were surrounded by hot water, only to be amplified by their fucking. Izuku could already feel the buzzing of orgasm approaching, his heart speeding up as he bit down on Shouto's shoulders for leverage.

Shouto fucked him hard and fast, his cock brushing against Izuku's prostate with every alternating thrust. His knot began to to catch, he hadn't realized that he was already about to come. Based off of Izuku's reactions though, he was about to too. He began pounding into Izuku's warm heat, hitting his prostate with every single thrust. Izuku started shrieking and biting his shoulders even more. If they weren't in the middle of passionate lovemaking, Shouto would probably wonder just how many bites his shoulders would be littered with.

Izuku felt his orgasm reach crescendo, and he opened his mouth in a wordless shriek as he went off. The contractions in his ass sent Shouto over the edge and he popped his knot inside before painting Izuku's channel with long streaks of cum.

Izuku melted against Shouto, clearly sated, and Shouto rubbed his back comfortingly. They stayed quiet for a minute, simply enjoying one another's company and the hot water.

Shouto motioned at Izuku's dick, that was still half hard between them, “Did you come from your ass?”

Izuku nodded, and yawned, snuggling up against Shouto's side even more.

“I love when you do that,” Shouto said, still rubbing Izuku's back.

Izuku sighed happily and touched Shouto's shoulder bites, “Sorry for… gnawing on you. Again,” He did it his whole heat too.

“It's okay,” Shouto said, bringing his hand to cup Izuku’s neck, where his own bite was. Izuku's body relaxed even more, the action was such a comfort. “You'll have my bite forever, so it only seems fair. Plus, I like it when you mark me.”

“I love you so much, Shouto,” Izuku said

“I love you, too,” Shouto said into Izuku's wide green eyes. “And I can't wait to spend the rest of our lives together.”
