Chapter Text

“Wow, I don’t think I ever expected to see myself so... vulnerable? Timid? There’s a range of adjectives I could use to describe you, but trust me, none of them are fairly pleasant.”

A dark, monotonous tone woke Izuku up from his slumber. Their pitch is in the average section, but they can reach high and low tones expertly. They’re clearly confident; much like a virtuoso performing; the melody of the key intertwining with the overall chorus. There’s amusement in the voice of the unknown person’s, that much Izuku can tell. He chirps with humour as he belittles Izuku. 

Izuku would retort something, but he’s too busy contemplating his sudden predicament. He doesn’t want to open his eyes, but aside from the telltale acrid scent of psychopathy and the pungent smell of manipulation, Izuku knows he’s in trouble. 

The colours blur behind his eyelids as he blinks repeatedly, his eyes opening with a burst of moss and onyx. He’s in a room, it’s fairly small with a decent amount of space to manoeuvre. The walls are lined with portraits filled with strings attached to every picture, and the floor is littered with sticky notes with indescribable words. 

He tries to sit up, but something stops him; grazing his vision towards the barrier stopping him from moving, Izuku finds out he’s handcuffed to a table. They’re holding his arms above his head, and his legs are cuffed in a spread position. Before Izuku can start to panic, a hand slams down next to his face. 

The gloved hand squeezes his face before tilting his head upwards, and he gazes into the very figure of himself. 

“You’re certainly quiet, aren’t you?” The voice lilts, the hooded eyes of jades darkening in nature. Izuku is confused; so very confused, but for now he should stick with obtaining information from this... doppelgänger? Was that a suitable word? 

“You’re... me?” There’s no other way to put it, and Izuku is sure this person was himself. It couldn’t have been a disguise, and he was sure it wasn’t Toga since she would have blown her cover immediately to coo over Izuku. 

“I’m sure that it’s fairly obvious I’m you,” a chuckle from him sank into Izuku’s ears vividly, “but I’m also not.” 

“What do you mean?” Izuku asked, his steady tone faltering when he felt the gloved hand stroke his face, before it pulled away. 

“You’re in my dimension, essentially. I was curious to see if I had taken other paths within my life, so when one of my henchmen offered to fulfil my interest, I had to accept. You’re in my domain, but don’t worry, this will only last for an hour or two. Everything that happens,” he gestured towards the room they were in with a sweeping arm, “will stay in here, and you won’t remember a thing.” 

This was too much for Izuku. His counterpart had kidnapped him from his own dimension? Was that even possible? Was that the only extension of their Quirks or were there multiple possibilities when considering the flexibility of the space time continuum? 

Izuku’s muttering caught the accepting ears of his counterpart who chuckled and smirked at Izuku. The boy opened his mouth but hesitated; was this version of himself nice? Judging by the situation he’s in, he can guarantee he was in dangerous hands. Still, it couldn’t hurt to give it a try. 

“Can you let me go, please?” Politeness was always the way to go, and it came as a subconscious habit towards Izuku. “Is there... a reason that I have to be bound like this?” 

The counterpart’s leering face came closer to Izuku’s, and he flinched when he felt the words of the other slap his face. “No, because nobody can know you’re here. And also, because I want to spend some quality time with you,” as he said this, he trailed a hand down Izuku’s chest before stopping at the waistband of his pants.

“Wha—“ 

His question was halfheartedly flung out of his mouth when the other Izuku rubbed his crotch, his palm feeling him through his pants. 

“Ahn, stop—!” 

The other Izuku laughed giddily in his direction before kneeling on the table Izuku was on, his posture engulfing Izuku’s figure. He laid in between Izuku’s knees, and the boy finally managed to see the whole outfit of the other’s. He wore a white button up with a black waistcoat, and some black slacks. His tie was done as badly as Izuku’s own. Guess that didn’t change at all. 

“I didn’t expect you to be so cute,” a hand insistently rubbed his crotch as he spoke, his gaze taking in all of Izuku’s embarrassing reactions, “especially for a U.A student.”

“What’s — ngh, wrong with U.A?” Izuku whimpered, the gloved palms trailed up his chest to work on pulling his blazer apart. 

“I hate it,” he ripped open Izuku’s shirt with strong arms and positioned himself closer to Izuku, “especially when I hate heroes.” 

“You — what? Why do you hate them? And c - can you please stop tou— hng, touching me!” Izuku let out a broken moan when the other boy toyed with his nipples; his slender fingers twisting and pulling the nubs. 

“Why? Because they rid me of a normal life. Because they expect too much of you that they never care how you’re doing. Because All Might is there, and he’s a piece of shit.” His voice rose in anger and he took it out on Izuku’s chest, a tug against his nipple was particularly harsh and made Izuku keen in pain, his arms shaking as his hips jerked upwards.

“He’s not!” Izuku shouted, his eyes glowing with stubbornness and fondness for his mentor, “All Might is an amazing Hero who has done so much for us and you shouldn’t hate him, not when he’s so strong and helps others and—“ 

“— and what?” The villain Izuku, Izuku now dubbed him that since he was starting to seem like one, pulled his pants and boxers down, his hands searching for a certain location as he held Izuku’s cock in a tight grip, the sounds squishy and unpleasant. 

“What will you do?” It was a simple question and Izuku tried his best to glare angrily through his rosy blush and high-pitched squeaks. 

“I’ll—“ Izuku’s eyes widened; he was going to use his Quirk on the villain, but when he attempted to harness his power of One for All, all that was achieved was an emptiness in his bones and a sagging feeling took over him. 

“You can’t use your Quirk,” his imposter sang ruefully, a wagging finger chiding him before returning to its place between Izuku’s thighs. “Those cuffs holding you in place? They’re Quirk defectors, which means for as long as you’re in them, you’ll stay immobile and Quirkless. But that shouldn’t be a problem for you, right? Since we both know that feeling.” 

This was bad. How did he not realise he couldn’t use his Quirk? Huffing and jutting his lower lip out, Izuku pondered just how much this male knew about him, and what events had taken place in his life. Their lives were most likely the same until they branched off before the U.A Entrance Exam, as that was the time Izuku met All Might and trained his body for All Might’s power. 

“Are you going to kill me, then?” Izuku reluctantly suggested; he didn’t want to die, not here and not now, but he needed to know the intentions of the boy atop him. 

Villain Izuku laughed, the sound as earnest as a pair of jeans being ripped; it made Izuku shiver in fear and a cold chill ran down his spine, his naked body producing goosebumps along his skin. 

The other male smoothed the inside of his thighs, his gloved hands grooving over Izuku’s crotch as he pressed his fingers into the fat of Izuku’s thighs. 

“No, there’s no point in that.” His answer made Izuku’s shoulders sag in relief, but it still didn’t lift the uneasy weight off his chest. “I normally kill all Heroes I come across, but you’re special, you know?” 

His statement had Izuku’s eyebrows scrunching in confusion. Was it because they look the same? “Is it because we’re the same person?” He rephrased his inquiry, and villain Izuku slapped his hands together, the action producing a loud clap. 

“Bingo!” His grin was wide and unsettling; he looked like he was ready to devour Izuku whole. “I’ll make you feel pain, but not in the way you expect!” 

His words left Izuku bewildered until he felt a finger circle his furled hole, and when he glanced up in shock, all he saw was the narrowed orbs of a sociopath staring straight through him. 

“You— you’re going to what?” His counterpart didn’t bother responding to Izuku and instead guided his finger inside of the male, the rough fabric of the glove catching on his walls searingly. 

“Aaah, wh - what? What are you doing down there!? Don’t tou - hnng, touch there!” Izuku squealed when another finger was added, and both of them abused a funny place inside of him. He didn’t know what it was, but it made something pool in his gut and sway his hips in time with villain Izuku’s thrusts. 

“Fuck, so tight. You’re a virgin, so I’ll make your first time pleasurable.” The other Izuku promised, and he quickly set to work stretching Izuku out. 

“N - no, no, I don’t - gah - I don’t want this! Let me go!” His body craved for more of his counterpart’s touch, but Izuku’s brain was scolding him for being so lenient, and for allowing the other to take control over his body so easily. 

“Don’t worry, you’ll love this. And, I mean, you already have lost yourself to pleasure.” Here he added another finger and jerked them all inside of Izuku, spreading his hole in a fashion that Izuku could only moan at. “Your mouth says you don’t want it, but these guys,” he let his other hand pinch Izuku’s taut nipples, eliciting a shudder from him, “and this one,” Izuku’s cock was clasped at the head, pre-cum smearing all over his glove, “tell the truth.” 

He must have had four fingers inside of him now, stretching him out fully in preparation for something bigger. Izuku wanted to kick back his legs and shove this guy away with his hands - to use his Quirk! - but all he could do was squirm in his restraints as he was reduced to a mess because of his lookalike’s cruel ministrations.

“You can embrace your slutty self here, where it’s only me.” Villain Izuku pulled his fingers away, the sound wet and unappealing to Izuku who blushed ashamedly. “After all, we’re the same person, right?” As soon as he said that, he shoved his cock straight into Izuku, his gloved hands sticky and insistent on his thighs as he set a fast pace of fucking Izuku. 

“Ahn, ah, hah, so - so deep, don’t! It’s too much!” Izuku was helpless in this situation, and villain Izuku used his body like he was a doll, weak and unable to do anything. It certainly didn’t help his burning face when he had cum as soon as his lookalike graced him with his cock. God, he didn’t want any of this and he hated how good it was making him feel. His gut was feeling strange and his body was heating up. This was so intense. 

“I would keep you, I really would. You’d be my little onahole, a cock-sleeve for me to use however I want. I’d fuck you everywhere and anywhere, and I’d make sure everybody knew who you belonged to.”

His dirty talking was punctuated with merciless thrusts and a harsh grip on his body; Izuku tried to close his eyes but villain Izuku wanted him to see who was fucking him, and he made a wet hand guide Izuku’s face to meet his expression: a mixture of horny, longing, and malice. His counterpart wanted to ruin him. 

“If you were disobedient, I’d just let one of the Noumus fuck you. They’d tear you apart, and you’d come back to me, begging that I’m the only one who’s good to you; I’m the only one who can fuck you as good as this.”

Squeaking, Izuku rutted his hips and squealed in his constraints; the other male was hitting that place deep inside of him, and it was making him feel so good! He hated it, but all he could do was time his hips to meet his counterpart’s crotch, his dick sliding against his walls in a way that made Izuku tighten up. 

“Why? Because I know you, and I know your body. Everybody else pales in comparison to just how good I can make you feel.” Villain Izuku bit Izuku’s shoulder with sharp teeth, and the skin broke as he suckled on his blood. Drool raced down Izuku’s chin and he arched his back when he felt his lookalike add more hickeys on his person and cum inside him; the liquid thick and viscous and scalding as it leaked out of Izuku like a faucet, his marked thighs quivering when villain Izuku didn’t get out of him. 

“Wh - why aren’t you getting out?” Izuku shakily queried, his body trembling from the onslaught of curdled pleasure he had been submitted to. 

Villain Izuku gave him a look of reverence and pity, Izuku’s blood spraying his chin as he crashed his lips onto Izuku’s. The boy could only whimper in surprise when he felt the coppery, metallic taste of his blood and a talented tongue drive its way down his throat, tasting every inch of him. 

When he pulled away, there was a string of saliva connecting them that made Izuku cringe. He jerked his head away and villain Izuku continued kissing his skin, biting here and there, sucking hard enough for there to be bruises tomorrow. Izuku was adamant he was going to have a hard time walking later on. 

“Do I need to?” His counterpart nuzzled his throat and licked a stripe up it, his voice rumbling against Izuku. “We still have some time left, so I should really mark you up this time. I mean, it’s not like you can do anything,” his calculating eyes sneered at Izuku, a dangerous smile prominent on his freckled face. “And you certainly don’t hate this; not with how your body’s reacting to the slightest things I do.” A lewd sound emitted from where villain Izuku’s fingers had entered his puffy hole alongside his cock. Izuku whimpered when he felt his evil self brush his gooey insides.

“Let’s have some more fun!” The look he gave Izuku was filled with promises of bad things, and Izuku couldn’t help but gulp. Please, let time run out soon!

When Izuku woke up, it was dark - pitch black - and he could move his body. Though it hurt horribly and he was sticky everywhere — especially inside, how did that happen? He was in his room, the All Might action figures soothing his ruffled mind as he sat up slowly, his lower body protesting at the slightest of movements. 

He’s been through worse, this will be fine. Drunkenly stumbling to his feet, Izuku limped his way to his closet to grab a towel before he went to his door and opened it. It must’ve been night, considering how dead it was in the hallway. Hobbling downstairs, Izuku had successfully made his way into the bathroom and was about to start undressing when he heard an awed voice behind him. 

“Woah, Midoriya!” Kaminari whistled, a teasing smirk pulling at his face. “Looks like you had fun!”

“... What..?” Kaminari only clasped a hand on his shoulder and leaned in, winking: “I won’t tell anyone, that’s for sure! Your secret’s safe with me!” And he happily walked off, a skip in his step. 

Izuku was more than disoriented about what had just transpired, but he shrugged it off and made his way to the mirror, checking himself to see if anything was amiss. Pulling his collar down, he saw a plethora of bite marks and bruises lining his skin. Did he get in a fight? But that still doesn’t explain why he felt so... empty and damp down there. After Izuku had splashed water on his face, he turned to his side and found a— note? Attached to his behind. 

Ripping it off, he turned it over and saw the following words that made him question just what exactly he had gotten into:

‘Hippity hoppity,’ it read in a neat scrawl, ‘your ass is my property.’ 

Shrieking, Izuku scrunched the note up and threw it away. He’d deal with that later but clearly somebody had had fun with him. This was bad! Who was it!? 

As Izuku panicked about this mystery lover of his, in another place, in another dimension, was another Izuku who snorted in delight, a hand cupping his chin. 

“He’s probably fainted via stress by now. But, happy birthday to him.”

Chapter Text

“... How...”

It’s halfheartedly stopped by his voice, or at least, the vocal cords attached to an alternate version of him, and he resists the urge to scrunch his eyes and wish this all away. Of course, his luck has never been impeccable.

“Magic,” his other version says, drawing out the syllables as he waves his hands in a jazz motion. “After our little fun date last time, how could I resist the temptation for another round?”

There’s a sly smirk on his face, and, in the distorted background murmurs of his classmates, Izuku clearly hears the subtle implication of: “guess how much havoc I’m going to cause.”

”Midoriya,” Aizawa-sensei calls out, both his head and his doppelgänger’s moving to stare at his teacher. “Care to explain?” There’s no shift in his tone, and Izuku suspects that he should acquiesce now, lest he gets house arrest again.

His villain version snorts and clasps his hands behind his head, emitting a nonchalant demeanour that has Izuku quietly sighing; of course he’d find this amusing. He’s still in the same outfit Izuku saw him in last time, but his gait is different; he’s waiting for something, anticipation sets Izuku’s nerves on edge and, presumably, his doppelgänger’s heady with delight.

Izuku shuffles his feet awkwardly, his shoes dig into the pavement of Ground Beta, and he glances up at his teacher. “This is... my villain version. He’s from an alternate dimension and can only transport here, or vice versa, via the work of a dimensional teleportation Quirk. It lasts about two hours, maybe less depending on the dimension?” Izuku was not liking this; after he had regained his memory of what happened the first time they met, he had laid his head on his knees and just— tried to forget that it ever happened.

But now with the boy right in front of him, beaming brightly as if Izuku had just told him the funniest joke ever, he was sure he would never get over his trauma.

”Wow,” the villain whistles, cocking his head to the side, “you remembered all of that? I feel so honoured!” He slides his hands down from his head and side-steps to get closer to Izuku, but he just backs away. “Aw, are you scared?”

His cheeks flush when he hears the mocking tone and Izuku just glares at his counterpart, not gifting him with the reaction he so desperately wanted.

The rest of his class is silent, all of their gazes on the villain, confusion evident in their eyes as they glance between him and his doppelgänger. Kacchan’s eyes are narrowed, his palms curled up into fists. He looks like he’s ready to punch his villain version, and Izuku’s ashamed that a part of him wants him to.

”This shitty villain needs to be taught a lesson!” Kacchan yells, and uses his explosions to land in front of the villain, his hand clutching the other’s collar. His counterpart only leers at him, joy in his murky orbs.

”Kacchan—“ He tries to intervene, but his opposite version raises a hand, stilling Izuku’s movement.

”It’s funny you’re going to teach me a lesson when you act like a villain yourself, Kacchan.” He smirks up at him, his curls bouncing with the action. Izuku swiftly turns his head to his teacher, his eyes imploring he do something.

”Hah? The fuck did you say, you two-bit extra?” Kacchan’s enraged, like usual, and he grips the other’s shirt tighter, his jaw locking as he grits his teeth in resentment.

”Enough.” Aizawa-sensei states, he sounds as tired as Izuku is of all of this. “Alternate Midoriya will follow me. The rest of you, continue practicing. Don’t slack off.” He makes sure to use his Quirk on his counterpart, and ushers him to walk with him. Evil Izuku only nods, pausing when he’s next to Izuku to give him an air-kiss and a timed wink before continuing forwards.

Izuku’s sure there’s distaste evident on his face, and he recoils in apprehension when the villain looks over his shoulder to stare Izuku dead in the eyes, something he can’t discern glints in his orbs. He jolts and his alternate self chuckles, gazing forward once again.

When they’re fully gone, his classmates are all over him, with the exception of some who patiently listen to his rambles about villain Izuku and the situation and the likes.

Iida reminds them all that they cannot have fun and disregard training, and so they all resume their paused workouts, intent on upgrading their move sets or reaching new peaks with their Quirks.

He changes into his gym uniform when school finishes, intent on heading to the gym to train his Quirk. He’s heading towards it when Aizawa-sensei appears before him, looking worn out and done with today’s events. Was he having trouble with his alternate version?

”Aizawa-sensei?” He questions, his eyes gauging his teacher’s reactions when the taller male leans his head downwards, coffee-coloured orbs digging into Izuku’s emerald ones.

”I need you to come with me. Your villain version is causing havoc, and keeps demanding you see to him.” He twirls on the soles of his feet and stalks away from Izuku, leading the smaller to the room that his counterpart is holed up in.

Izuku hurries to catch up with him.

”Is that all he’s been saying? Anything else?” He hopes the villain doesn’t want to see Izuku for... that purpose, but that predatory look he gave him earlier may as well seal his fate already.

”Just that. He says he’ll answer any questions as long as you’re the one asking them.”

Just him? They quickly make it to the room, his teacher opening the door and allowing Izuku to enter first. He mumbles a thanks and sets his gaze upon the occupants within the room. Only All Might is there, the other teachers are probably off working today, or have left Aizawa-sensei and All Might to deal with this conundrum. It’s some sort of conference room, where they are, and he imagines this is where the teachers hold their meetings.

His villain self is sitting at the other side of the table, his chin on his hand as he fake yawns, half-droopy eyes widening with pleasure when he spots Izuku’s form.

”Young Midoriya,” All Might greets him, strolling towards him and placing a large hand on his shoulder. “This is a situation that is quite complex, and neither Aizawa nor I want you to be alone with your alternate self, but he seems aggravated by heroes, even if it is just us. He is especially angry,” All Might’s stare travels to his counterpart, who sets his jaw when he sees All Might, and returns back to him, whispering, “that I am here.”

Izuku nods; his evil self doesn’t like heroes and detests All Might, which is stupid and something he would probably never figure out (it’s All Might, how could anybody hate him?). “Aizawa-sensei updated me on the situation, so I’ll do my best to get answers out of him, All Might!”

He’s determined to make the other Izuku talk. If he has to use force, then so be it. The other makes no indication of hearing Izuku’s declaration, continuing to leisurely observe his figure, his eyes trailing over Izuku’s body. It makes him shiver. The other coos at him.

”Midoriya,” Aizawa-sensei interrupts, “we will be outside. If anything happens, yell and we will take care of the situation.”

”As soon as he answers some questions and agrees to not endanger any of the students here,” All Might pulls out a piece of paper and hands it to Izuku, who shoves it in his pocket, “you are free to leave. You don’t need to be concerned with this any longer than you have to.”

He smiles up at his mentor. “Don’t worry, All Might, I’ll be fine.” He reassures him. All Might swipes his stare to Aizawa-sensei, and they both take their leave, reiterating that if anything happens, Izuku is to immediately leave.

The door closes with a click and Izuku is left alone with his counterpart.

”Well?” He drawls out, wagging a finger at Izuku in a ‘come hither’ motion. “Aren’t you gonna interrogate me?” Izuku grimaces but walks around the table until he’s a couple steps away from the villain.

”Try anything funny, and I’ll have to use my Quirk on you.” He won’t harm him, no, he can use a bit of his power to subdue his evil self.

”Ooh, scary.” The other snidely imitates a terrified expression and stands up, facing Izuku. “Do it, then.” He simply says.

... What? “What?” He repeats, his expression one of bewilderment. Why is he allowing Izuku to call the shots here? He has something up his sleeve, that can only be the answer. He’s going to do something the minute Izuku uses his Quirk.

He’s overthinking, mumbling out loud, and doesn’t register black tendrils whip out to grab at him. He jerks away at the last second and jumps away from the tendrils. The villain quirks his lips. 

More tendrils shoot out around him, intent on capturing Izuku. He manoeuvres his body around them, fast on his feet, and manages to execute a feint that allows him to go behind his other self and pin him to the table, his hand firm on the other’s wrists and his other hand steady on the table.

”I told you not to try anything funny.” He yells out, “now answer my questions.” He uses his free hand to fish around in his pocket for the piece of paper.

Villain Izuku uses this as an opening to pin Izuku to the table, flipping them over expertly. He glows with the same energy Izuku has when he uses One For All, the black tendrils plucking the paper out of his hands and securing him to the table.

”Did you think it would be that easy?” His alternate self murmurs, calculating eyes scanning the paper.

”Midoriya?” Aizawa-sensei calls out, “is everything okay?” He’s probably worried something happened due to them both fighting.

”Everything is fine, sensei!” He replies back, settling his eyes on the form above him with serious intent. “Just a little scuffle.”

”Don’t overdo it,” his teacher reprimands.

Izuku doesn’t respond.

”A scuffle? Is that what this is?” His villain form leans over him, his minty breath ghosting over Izuku’s face. “More like a one-sided fight. I’m more powerful than you, how powerful? Well, how about this,” he gestures to the paper, wiggles it around, “for every question I answer, you have to do something for me.”

Izuku is appalled. “Why should I accept those conditions?” He uses 5% of One For All and flips them over again, breaking free of the bonds.

He’s straddling his evil version, and the other seems to notice, too. He rests his palms on Izuku’s hips, not budging from his position.

”Because not only would it be terrible if your teachers came in to see this situation, but,” he curls his lip, rubbing circles on Izuku’s waist, “I can overpower you. How? Simple.” He sits up, Izuku sitting in his lap.

”I have perfected all of my Quirks, including One For All.”

His sentence makes Izuku’s eyes widen. Quirks? He has more than one?

”Want to know more?” Izuku is stupefied and nods numbly. “Then you know what to do.” He rolls his hips against Izuku’s bottom, something stiff poking him.

”Fine.” He agrees; if what he’s said is true, and it probably is considering he used two Quirks already, then Izuku was fighting a losing battle. Besides, he wouldn’t do anything too bad since his teachers are right behind the door.

”Great!” He exclaims. “Touch yourself.” Izuku jerks away from his touch when his other version squeezes his behind.

He grits his teeth and slides his hand inside his gym pants. His evil counterpart grabs his wrist. “I want to see.”

Izuku hates this stupid power play, but he gets on his knees and slides his pants down an appropriate amount that would allow him to slip them up easily if someone entered the room. He’s about to sit down when his doppelgänger tells him to take off his boxers, too.

Thankfully he wore simple green ones today. Imagine if it was his All Might ones. That would be humiliating.

He slips them down mid-thigh, and sits on the other’s lap. “Answer the question, then.” He demands.

“Naughty boy,” he chides, lightly slapping Izuku’s ass, “do what I’ve said and then I’ll tell you.”

He deflates, and wraps a scarred hand around his flaccid cock. He strokes up and down, gathering pre cum, and directs his eyes away from the other’s. He isn’t allowed reprieve, though.

A gloved hand, the dreaded gloved hand, grips his chin and forces him to look at the other male. He flushes and speeds up his movements, wanting to get this over with. His cock is hard and sloppy and he feels he’s nearing his release.

He’s ready to come when another hand grips the soft head of his cock, halting his orgasm as he groans frustratedly, quickly biting his lip when he remembers his teachers are outside the door.

”I only said to touch yourself, not to cum.” He cheekily quips at him. “You did good, so I’ll answer the first question.” He lets go of Izuku’s chin and scans the paper next to them. “What universe do I come from? What an ambiguous question; it’s one of the universes where nothing goes as planned, I suspect, and I— we, don’t become heroes.”

”Next.” He orders. “Finger yourself.” Izuku’s cheeks redden. Does he have to? But his doppelgänger was keeping his end of the promise, so he guesses he has to go through with this.

He sticks two clean fingers, ones that aren’t covered in his pre cum, thank you, in his mouth; swirling his tongue around the digits until he’s sure he’s accumulated enough saliva to coat his fingers. He withdraws his fingers, flinching at the mess of spit on them, and brings his hand behind him.

He leans on the other male, a small palm on the table, and spreads his legs wider so he can guide his hand to freely poke in between his thighs. He guides a spit-slicked finger to his entrance, taking a harsh breath, and presses the tip in. It’s uncomfortable but it’s not painful.

He wiggles the rest of his finger inside of him, the sensation is strange as he’s forced to feel his own walls fluttering around his digit, and stills when all of it is in him.

”Well done,” he’s starkly reminded of the other and jumps, involuntarily squeezing around his finger. “You took it so well, now for the next one.” Izuku lets out a gasp, sinking his teeth into his bottom lip to not alert the teachers to what they were doing.

He slowly presses the other digit to his hole, sliding his finger in alongside the other. There’s more of a stretch this time, he’s forced to accommodate around two fingers now. He’s just glad they aren’t thick or long. He ends up getting it fully inside, and shifts when both fingers are completely inside him.

”Another one?” His doppelgänger happily inquires, a laugh forming when Izuku shakes his head. He only slicked two of his fingers, another one would be too painful.

”Ahh, not enough lube. I’ll help out, then.” Izuku’s not sure what he’s expecting, and the sensation of something cold slipping between his legs, coiling around his hand, catches him off guard.

”What—?” He softly gripes out, still wary of his teachers outside the door. He really hopes they don’t count the silence as Izuku being in trouble.

He squeaks in discomfort when the cold tendril — he assumes it’s that based on its flexibility — pokes his stretched hole, dancing its way in him until it passes his fingers. It’s, thankfully, not relatively thick but is thin and long, filling parts of him he’s sure he’d never be able to reach.

”Ah, hah, n— not there!” He whimpers, bucking away from the touch, that only results in him rubbing his wet cock against his alternate self’s stomach. The tendril doesn’t relent, and keeps insistently stroking that spot inside of him. He whines as his thighs tremble, clenching crazily around his fingers and the tendril. He’s about to cum, he wants to cum, and the tendril senses this and speeds up its strokes.

He wails silently, his eyes glossy with tears as his head drops on the other’s shoulders. He tries to close his legs, but two tendrils clasp his ankles and separate his trembling legs further, keeping him in place.

Another tendril joins the one inside of him, worming its icy way in until it hits that spot and abuses it. He pushes his hips backwards involuntarily, forcing the tendrils and his fingers to go deeper inside.

”Ngh, nn, hah, s— stop, too much!” He babbles pleads into the shoulder of his evil self. It’s too much, he’s going to cum any minute now.

”Poor baby.” His counterpart’s hand snakes its way between their bodies to grip at his dripping cock, thumbing over the head before squeezing it. The tendrils stop their torment and still inside him. He makes a noise of uncertainty. He was so close!

”Is that better?” He knits his eyebrows in mock-comfort. Izuku doesn’t lift his head up, letting the scent of mint and pinewood invade his senses. “You can cum when I tell you to. Right now,” he peers over his head, he assumes it’s that, to check the paper. “It’s time to answer another question!” He’s probably eager because he gets to request something else from Izuku.

”Do I have any affiliations with All For One, or One For All? They’re cheating; this isn't one question. I’ll answer it, though, since you’ve been so good,” he controls the tendrils to curl around that spot inside of him, making him see stars as he bucks forward into the hand gripping his length. “Yes to both. Next request; ride my cock.”

Izuku lifts his head up, mouth gaping; from his doppelgänger's stupidly short response and the tendrils coaxing out moans from him.

”Y— you didn’t, ah, that’s too short, hah, ahh, nn.”

”Oh.” He’s awarded a resolute response. His counterpart’s free hand smooths circles onto Izuku’s slender back. He nips his ear, taking advantage when Izuku moves his head away, baring more of his neck to the other’s delight.

”They didn’t ask for a detailed answer; only for me to affirm my affiliations, not how long I’ve had them or what they entail. Not my fault they didn’t think their question through properly.” He shrugs and Izuku winces; at this rate they’ll take forever to go through all of the questions.

”Young Midoriya?” All Might tentatively asks, rapping on the door with his knuckles. They’ve been silent for a while. “Have you made progress?”

Izuku instinctually tightens around the tendrils and his fingers, and chews on his lip, trying to regain some of his voice that doesn’t sound like he’s been jerking off.

”G—good,” he tilts his head to the side to check the paper, there’s not many questions on them, just a couple, but he doesn’t much left. “Halfway there!” He says, he has to hurry this up before they become impatient and break the door down.

”Well done,” All Might congratulates him, “Aizawa-sensei has gone to check up on a mishap in one of the Hero classrooms. Can I come inside?” He updates him on the situation; Izuku’s blood runs cold.

”No!” He shrills, “I mean, no,” he says softly, “just one more question. He says he’ll answer this question of mine.”

”Oh, if that’s so, I’ll let you continue. We don’t have much time until he goes back, so make it quick.”

He’s guilty he has to raise his voice at All Might like that, but he’d rather not have his idol see him so debauched.

”Kudos to you,” the tendrils slip out of his body with a wet shlick! as his doppelgänger gives him a tight-lipped smile. “For narrowing the time you have to ride me. Better get to it quickly, before your Hero sees you in a shameful position.” He settles both hands on Izuku’s hips.

Izuku scoots his fingers out of his hole and makes quick work of jerking the other male’s cock from its confines. He kneels above his stiff cock, the bulbous tip smearing pre cum on the inside of his quivering thighs. He wraps a hand around the cock and lines his hole with the head.

Squeezing his eyes shut, he reluctantly lowers his hips down until the tip penetrates him, stretching his puffy hole wide. He’s glad he’s average in that department down there, otherwise he’d really be splitting himself open on his own dick.

He gets another inch inside of him. The pace he’s going at is slow, but Izuku has to get used to it first. He doesn’t want to tear anything.

His other self seems to disagree with his thinking; he grips his round hips tightly, and forces Izuku down on his cock, filling him up and stretching him fully.

”Aah! W—wait, too fast, too deep! Hah, ah, ahh! Wait!” He clasps his arms around the other’s shoulders, his toes curling in his shoes as he tries to get used to being filled.

”We don’t have much time. Hurry up.” He whispers mercilessly in his ear and thrusts up into Izuku, making him squeal and hold the other tighter. He’s apparently a bit too loud as All Might worriedly tells Izuku to leave if he was being harmed or in a precarious position.

”I’m, ah, o—okay, All Might!” He trills, arching his back when the Izuku underneath him shuffles and angles his cock to hit that special spot inside him. “Nearly done!”

His eyes dilate in fear and pleasure, and he shakily lifts his legs up, dragging half of the length out of him before descending down, continuing in the same rhythm.

He bounces up and down, tightening around the other’s cock as he gulps, his breaths coming out irregular and tears rolling down his cheeks.

”You’re so pretty.” Maybe he‘s too delirious or out of it, but it sounds like a genuine compliment from the other. “Riding my cock like that, making those cute noises, crying so sweetly.” His teeth directly target Izuku’s neck and bite down on the supple skin there, sucking to form a hickey.

”All you need to do is beg for me to fill you up, and you’ll be done. That’s all, you’ll do that, won’t you? Wouldn’t want All Might to see his protégée taking cock like a champ. I mean, maybe you’d like that? After all, all you’re good for is,” he clamps his teeth on the skin at the base of Izuku’s neck and draws blood, making him moan helplessly, “seducing people with that cock-hungry face of yours.”

”Pl— ahh, please! Please let me, nn, hah, c—cum!”

Izuku is sure he’s close to nearing his orgasm, and he hopes he’ll be allowed to, this time. His other version senses his train of thought and pulls his hair in a jarring manner, causing Izuku to gasp and drool as he tightens around him.

”Fuck, fuck, so good. So tight. I can’t get enough of you, it’s so fucked up. I’m gonna fill you up with what you want. Nobody else can fuck you better than me!” He increases his pace and Izuku bounces more erratically, both of them nearing their orgasms.

“Gonna, ah, hah, cumming!” He whimpers when he cums, the substance splattering on the other’s hand, and moans lowly as the villain’s cum sloshes inside of him, some leaking down his thigh.

”Man, you sure know how to entertain someone,” he taunts him. Izuku’s too fucked out to reply with a response of his own, and pushes at his shoulder to indicate to let go of him.

”Go... answer the next question,” he croaks out, focusing on getting up. The other Izuku lets him stand up and pull his boxers and pants on, the cum trailing down his thigh is uncomfortable but he’ll survive. There’s nothing here he can use to clean up with.

His counterpart tucks himself back inside his pants, lazily resting his eyes on Izuku’s disheveled form. He shoves his soiled hand in front of Izuku’s face.

”Your cum. Clean it.” Izuku doesn’t spare a second thought and grabs the palm, his pink tongue darting out to lick up the remnants of his release. When he’s finished, he pulls back just in time to see the villain laugh.

”Holy shit, you’re nasty. Licking your own cum.”

... There was no reason to do that. He’s only now aware of how dirty that makes him look.

All Might interjects before he can open his mouth to defend himself. “Young Midoriya, I’m coming in.”

”Okay, All Might,” he yelps, having forgotten he was still there.

He checks the table for any weird substances and jumps off it and away from his doppelgänger, brushing his form to smooth any creases.

The other rolls his eyes and hops down, clutching the paper.

”Are you okay?” All Might asks him. He nods tiredly.

”Christ, being surrounded by Hero wannabes is making me exhausted.” He takes long strides to stand in front of All Might. “Here,” he shoves the paper at All Might, “take it and leave me alone. I’m going back. This dimension sucks ass.”

”Good business as usual, Izuku.” He mockingly salutes at him over his shoulder and pushes past All Might.

”Sorry, All Might. He’s quite.. infuriating.”

”It’s understandable, my boy.” He goes to stand next to All Might when the door closes. “Let’s see his responses.”

They peer at the paper. They both sweat-drop.

’Lmao bitch you thought’ is in a neat scrawl at the top of the paper.
