Behind Closed Doors

Summary:

Everyone has sides of themselves no one besides themselves knows, but when Midoriya accidentally discovers what Jiro hides behind closed doors, he'll find a part of himself not even he knew of.

Notes:

First time writing smut. Might be cringe, but I got off to it so that has to count for something.

Contains: Crossdressing, a genderbent Jiro, oral/cock worship, mating press, degradation, a copious use of the word "slut," and a little actual romance at the end for the boner in your heart.

You have been warned.

Chapter Text

“That was awesome Mido-bro!” Kirishima’s voice filled the common room of the 3-A dorms as he flung open the door, a sheepish Midoriya following as he stepped inside. “That new super move was crazy!”

“It’s nothing too special.” Midoriya deflected on instinct. Even in the tail end of their third year at U.A., despite several attempts from his classmates to help boost his confidence, Midoriya Izuku was still the same. Any amount of praise? Too much. Recognition from the press? Unearned. And his female classmates telling him he’d earn the spot of “Hottest Hero” in every tabloid and gossip rag? Pity at best, a joke at worst. “I still need a lot of work before I’m good enough with Blackwhip to use that move in the field.”

“Maybe, but if anyone here could figure it out, it’d be you.” Kirishima pressed, not willing to let his friend put himself down in the slightest.

“Yo! Where’ve you two been?” Ashido called out from the sofa, distracted from the sight of Bakugou getting her butt handed to her by Kaminari in a game of Super Smashing Heroes. Naturally skilled at most endeavors she applied herself too, video games were one of the few exceptions. Refusing to admit that and easily riled into a game by prodding at her pride, the sight of her fuming as her virtual All Might was battered and beaten was a common one, matched only by the sound of her cursing out whatever other character she was up against.

“God damn it, Mirko is un-fucking-fair! Pick a different character, chargedolt!”

“I already did. Five times.”

Ignoring the argument with years of practice, Kirishima answered his friend. “We were just getting some extra quirk training in. Mido-bro showed off this cool new super move with Blackwhip! It was like…” As he made his best approximation of the sight through waving his arms and making nonsensical sounds, Katsumi shot up as she pitched her controller against the ground. The device bounced, cushioned by a protective wrapping bought for her after breaking three controllers in a single week during their first year, all while Kaminari smugly leaned back having earned another “Bakugou-rage-quit” to his name.

“This game is bullshit! Ugh, who’s making dinner tonight? I’m not stomaching Icy-hot’s crimes against taste right now.”

“It’s me.” Midoriya answered. “And I think we’ve got the ingredients for curry. I’ll make you a batch how you like it.” After a long, rocky, but now improving friendship, Midoriya knew the girl’s tastes well. There was nothing that calmed the angry blond down like a plate of curry, spiced to the point of nearly being considered a health hazard.

“Fuckin’ better…” She gumbled before stomping towards the stairs leading to the girl’s dorms. “Someone get me when dinner’s ready. I’m not gonna stuck around and hear the glowstick’s bragging.”

“I haven’t even said anything!” Kaminari complained.

“I know you’re thinking it!”

“Well, guess I should get started on dinner then.” With a wave, Midoriya left the three to their own devices and made his way to the kitchen. As his mind wandered to the list of things he needed to prepare first, he was too distracted to notice the head of purple hair stepping out from the kitchen until he collided with the person in question.

Letting out a startled gasp, Jiro Kyoku barely nudged the muscular frame of Midoriya while being sent sprawling backwards himself. “Jiro! Are you okay?” Grabbing the boy’s hand, Jiro blushed as he was lifted to his feet like he weighed nothing. “You’re not hurt, are you?”

“W-wha…” The punk responded lamely before recomposing himself with a forced grin. “Uh, y-yeah, I’m fine. I’m tougher than I look, Green.”

“That’s a relief. But, are you sure you’re alright? You look like you’re burning up.” Placing a hand against Jiro’s forehead before he could stop him, Midoriya frowned as Jiro’s face grew even brighter. “Do you need me to take you to Recovery Girl?”

“N-no, I’m fine, dude.” Jiro pushed away the hand as he said so. “Just… got a fever all of a sudden. I’m gonna go rest, probably won’t make it down for dinner.” Quickly darting to the side, Jiro paused before he could bee-line it for the stairs. “But, uh… thanks. For the concern, I mean.” At that, the punk made way for his room, leaving a still concerned Midoiya at the entrance of the kitchen.

With no way he could help Jiro right now, Midoriya had no option but to content himself with preparing dinner. As his hands carried out the familiar task on their own, his mind was free to run rampant with every worst case scenario he could think of. What if it wasn’t just a fever? What if Jiro really did need medical attention and wouldn’t get it in time hidden away in his room? What if he was in terrible pain at this very moment, too indisposed to even call for help?

The sound of the rice cooker beeping caught his focus, and Midoriya did his best to calm himself. It was probably nothing, and Jiro was right that he was tougher than his thin frame suggested. It wouldn’t help to worry. Still, the niggling thoughts at the back of his mind wouldn’t leave, and so as he gave the dish a taste and finding it ready, he prepared a special plate for Katsumi spiced to how she liked it before portioning out a serving of curry and rice that wouldn’t burn a hole in the floor. Stepping out of the small kitchen, he found Yaoyorozu had come down sometime while he was cooking. “Jiro looked sick earlier and went to his room, so I’m going to bring him some food. Can you let the other’s know dinner’s ready while I’m gone?”

After Yaoyorozu said she’d do as much, Midoriya made for the elevator and punched in the button for the floor shared by him, Jiro, and Mineta. The latter was absent from the dorms due to his work study, which no doubt was some relief to the punk. Even Midoriya with his unenhanced hearing had to invest in some quality earplugs to ignore Mineta’s… private time, and he could only imagine what it must have been like for Jiro.

Once the cabin stopped and the doors opened out to his floor, Midoriya made his way to Jiro’s room and raised a hand to knock. Before his knuckles met wood, the Hero in training paused as he heard the muffled sound of Jiro moaning and panting in what sounded like pain. “Jiro? Are you alright?”

He was answered only with more moans, before he caught the unmistakable sound of his friend through the door. “M-mido…riya…” Jiro sounded out of breath, barely able to form the syllables of his name before going right back to panting.

Panic sparked to life in Midoriya’s chest, his worst fears confirmed. Throwing open the door, he stepped inside. “Jiro, are you alright? Do you-” Only to freeze. Instead of finding what he expected, Jiro curled up on his bed barely clinging to consciousness, he found something he never expected of the punk.

In the middle of his room in front of a full length mirror, Jiro was dolled up in the female U.A. uniform and makeup as he moaned not in pain, but in pleasure, bouncing on a plastic, green dildo like the most practiced escorts in the red-light district. His cock flopped around, two, maybe three inches long, and slapped against the ground every time he bottomed out.

Jiro was turned away from him, giving Midoriya a perfect view of his tight, perky ass clenched around the fake cock stuck to the floor, but he could see in the mirror’s reflection that Jiro’s eyes were closed to better imagine his fantasies. “F-fuck… give it to me, Midorya…” Drowning himself in pleasure, Jiro didn’t even hear Midoriya’s approach to his door or notice the fact he was right behind him. If Jiro had, then he might have gotten to see the way Midorya’s dick shot up at the sight, straining against his gym shorts and threatening to tear free.

A confusing flood of arousal washed over the verdant-haired Hero. He had always assumed he was straight, never having any reason to think otherwise. All of his past crushes were girls, and the most recent object of desire was his classmate Uraraka, but he couldn’t deny what the sight of Jiro fucking himself as he called out his name did to him. ‘It’s… it’s just because he’s dressed like a girl…’ Midoriya rationalized. ‘If it weren’t for that, if he didn’t pull it off so well, then… then I’d just turn around, close the door, and never bring this up to anyone. And I’m going to do that, right now. Right. Now.’

But he didn’t. He couldn’t. His eyes were transfixed watching Jiro’s ass rise and fall, his cock throbbed every time Jiro moaned out his name. Midoriya was so captivated by the hypnotizing sight, he didn’t even realize his grip on the plate he brought was slipping until it clattered on the floor, the sound finally snapping Jiro from his own lust-fueled haze. “M-midoriya!” He shouted in panic rather than the desperate, needy whine of just moments before. Trying to rise to his feet, Jiro moved to pull himself off the dildo only to slip in the rush and come crashing down, the plastic dick ramming against his prostate and pushing him over the edge. Several pearly white ropes spilled over his floor as Midoriya’s own cock painfully strained against his underwear at the scene. Midoriya couldn’t deny it any longer. He was definitely bisexual, and his lower head was screaming at him to fuck this twink into a drooling mess. Shuddering from aftershocks of the orgasm, Jiro tried to claw back what dignity and sense he could. “W-what are you doing in here! Get out!”

Midoriya stood in silence for a beat, no even registering the command. Before Jiro could try to rise once more and shove him out of his room, the verdanette asked a question that froze the crossdressing punk in place. “Why were you saying my name?”

In an instant, Jiro’s blood froze in his veins. “You… you heard me?” He asked, his voice trembling in time with his body. “How long were you standing there?”

“Long enough.” The sensible, heroic part of his mind was demanding that he apologize, promise Jiro he wouldn’t ever tell anyone about what he did in private, and run back to his room to deal with his massive, throbbing erection. The rest of his mind had stuffed the sensible part into a proverbial trunk before telling Midoriya to push this as much as he could. “How long have you been doing this?”

“The… the clothes?” Jiro stammered. “Or… you?”

“Both.”

Jiro shuddered at Midoriya’s authoritative tone. The notion of lying didn’t even enter his mind, the crossdresser instead confessing to every lurid detail. “I… I started crossdressing in middle school. It started with a dare… walking across the city in a girl’s uniform. I… pulled it off well enough that someone tried to flirt with me and…”

“You liked it?”

Jiro could only nod, his eyes not reaching up to meet Midoriya’s. “I couldn’t get it out of my mind. Whenever I tried to jack off after that, I… I kept imagining getting used like a girl, so… I went out and got a dildo.” Jiro nervously fidgeted on the plastic cock. “And after that I… I couldn’t go back…”

Midoriya hummed in acknowledgment, every single word of the story threatening to send his cock ripping through his shorts. “And when did you start thinking about me?”

Jiro’s lip wavered. “In our first year… during a training exercise. I fell from a ledge before you jumped up and caught me like… like I weighed nothing to you…” Midoriya could see the twink’s softening dick twitch as he recalled the memory, a day he remembered as well. He could recall Jiro’s blushing face as he cradled the boy in his arms, simply assuming it a case of embarrassment from having to be saved, but that he now knew was barely hidden lust. He looked just like he did earlier today...

“Is that what gets you off then?” Midoriya asked, a cruel smirk far unlike his typical smile. “Being treated like a girl?” Jiro’s member jumped at the word. “All while a big.” Another twitch, a bead of cum forming at the tip. “Strong.” His dick was nearly back to full mast, “Man puts you in your place?” The whine that escaped Jiro’s lips was proof enough to Midoriya that he had hit the mark. He chuckled at the sight of the tough-as-nails punk of 3-A being reduced to a moaning, leaking mess before him. “Alright then. That’s all I needed to know.”

“Ah…” Jiro panted. “Alright?”

“Yeah. I’ll leave you alone now, so you can get back to it. That is… if you want me to leave.” Jiro’s heart began to race, not willing to believe that his fantasies might just get fulfilled this night. “Do you still want me to leave?” Not trusting his voice, Jiro shook his head. Turning to close the door, the sound of the latch clicking rang out like a bell, and deep down Jiro knew there was no turning back from what was about to happen. Stepping closer, the lingering scent from Midoriya’s workout assaulted Jiro’s nose and left him flush faced and panting. “What do you want then?”

“You… you know… please.

“Yeah, I do.” Midoriya answered before slightly leaning forward. “But I want to hear you say it.”

Jiro licked his lips, swallowing to try and soothe his dry throat. For as embarrassing as it was to be found in his room like he was, speaking aloud every dirty act he wanted done to him felt like one final step he could never take back. This wasn’t fooling around in private, something he could stop at any time and forget about as some weird phase. If he caved now, if he let Midoriya have his way with him, then he could never call himself a man again.

Jiro didn’t hesitate.

“I want you to fuck me!” Jiro shouted, the force of his voice taking both of them aback. The flood gates had crumbled however, and Jiro couldn’t stop himself if he wanted. “Use me like a toy! Pick me up and slam me down on your cock without even asking! Bend me over and fuck my brains out until I can’t even remember my name! Turn me into a cock-addicted SLUT!”

Midoroya’s eyes went wide at the sudden explosion from the twink before he grinned. “Well,” He moved closer until his crotch was directly in Jiro’s face. “When you ask so nicely, how could I say no?” As he hooked both thumbs under his waistband, Jiro practically vibrated in excitement. With one quick motion, Midoriya slipped his shorts down and let his cock flop out onto Jiro’s face, the slut-to-be stunned silent once half his vision was overtaken by the largest cock he had or would ever see. It was as thick as a soda can and longer than his forearm. The heat and smell wafting off the third leg made Jiro’s head spin as it throbbed in time with Midroriya’s heartbeat. It was a massive, dizzying, parody of a penis the likes of which one only saw in hentai and ero-games. It was going to absolutely destroy him if Midoriya tried to make him take it. It was perfect.

“H-how…?”

Before All Might had given Midoriya One for All years ago, his dick was like the rest of him, perfectly average. During his first year though, when he first began to notice the changes to his manhood, Midoroya nervously asked Yagi if it was normal for One for All to affect his body. Assuming his successor was referring to how comically muscular the number one Hero was, All Might confirmed that as he adapted to One for All, One for All would in turn adapt his body to it, over time giving him a greatly increased muscle mass to safely wield the quirk without straining his body. With a bright red blush, Midorya had to clarify he was talking about changes “downstairs” for Yagi to get the meaning. The Hero sheepishly confirmed that, yes, that had also happened to him.

Knowing that it wasn’t anything to be concerned over, Midoriya never gave it much mind after that. He was never one to obsess over something like who in class had the biggest dick, reasoning the only person it would have ever concerned would be whoever he eventually ended up sleeping with, if he ever did.

Now that it actually was going to be using on someone however, Midoriya took no small amount of satisfaction from the sheer disbelief on Jiro’s face. He took in every detail he could of the cock-shocked twink, burning the sight into his mind. Jiro was only ever going to be like this once, after all. “Let’s just say it’s a side effect of my quirk.” He joked, unsure if Jiro was even listening with how laser-focused he was on the prize in front of him. That was quickly answered once Midoriya gave him an order. “Now show me how much you want it.”

Needing no further prompting, Jiro stuck out his tongue and slowly licked the underside of his shaft from base to tip, savoring the taste as he did so. The odor that filled his nose was redoubled as the taste filled his mouth, sweat and musk drowning out any other thought than to continue worshiping the slab of flesh the towered above him. It was nothing like his own cock, if it even deserved to be called as much compared to the obelisk casting a shadow over his face. Every vein pulsed with sheer virility against his tongue, promising him the reward he so desperately craved if he but only kept debasing himself. Nearly lifting himself off the dildo he was perched on just to reach the angry, red tip, Jiro slammed himself back down in his haste to place his nose back near the two pungent sacks of churning seed that hung bellow it, deeply inhaling Midoriya’s scent. It was, to borrow from Kirishima, nothing short of manly.

“Fhuuuuck…” Jiro whined, his body shuttering from the sheer arousal he felt just licking at a real cock for the first time in his life. He continued on, lathering every inch of Midroya’s rod with his spit, sucking at the tip for the pearls of cum forming from the slit, huffing the stench like a desperate addict, and leaving purple kiss marks on the heavy, swinging orbs beneath while his jacks wrapped around the shaft to jerk Midoriya off. How long Jiro continued to worship, he didn’t know. It could have been only a minute, it could have been an hour, time being worthless in the face of the true bliss that was servicing such a thick, hard, cock. It was everything he dreamed it would be, and in the back of his mind Jiro was cursing at himself for not throwing open Midoroya’s door, bending over, and letting the Hero in training have his way with him years ago.

“God, you’re such a slut.” Midoriya said through clenched teeth, his head thrown back from the pleasure of the Jiro’s ministrations. “I don’t even need to fuck you, do I? You’d be happy just worshiping a real man’s cock, wouldn’t you?” Midoriya, his brain as overtaken with lust as Jiro’s, still felt somewhat uncomfortable saying such denigrating things about his friend – although the feeling of said friend dragging his tongue across his dick in abject reverence did help somewhat. But he was still a people pleaser at heart, and If the punk wanted to be treated like a whore desperate for a taste of his cock, then he would give Jiro what he wanted. “But I’m not here to make you happy, you’re here to please me.” Midoriya grabbed a handfull of purple hair, pulling Jiro away from sucking at his nuts with a pop as the seal of his lips broke. Before the twink could even so much as whine at losing his treat, Midoriya placed the tip of his shaft against Jiro’s lips. “And I’m not going to cum from just your tongue.”

Staring cross-eyed at the cock head for a moment, Jiro’s gaze turned up to meet Midoriya’s. The verdanette could see no small amount of fear in Jiro at the idea of forcing such a monster down his throat, but it was nothing compared to the lust that dominated his gaze, his mouth already hanging open with his tongue sticking out as if offering permission. He wasn’t going to have waited for Jiro to be ready in the first place, but it was nice to know the slut was just as eager as he was.

Jiro struggled just getting the tip past his lips, circling his tongue around in a vain attempt to lube it up enough to get it past his jaw. “Is this your first time giving a blowjob to something that isn’t plastic?” It was, but before Jiro could pull away to answer Midoriya used his grip on the crossdressing punk’s head to force it further. “Then let me help.” Jiro gagged nearly instantly, doing his best to relax his throat as his body tried to force the intrusion out. Midoriya’s grip was iron though, and nothing Jiro could do would have been enough to pull away, had he even wished to try. “Just… take it!” With another pull on his hair, Jiro was brought halfway down on Midorya’s cock in a single moment, his eyes flying wide open as tears began ruining his mascara and painting black tracks down his pale cheeks.

For several seconds he was held there, trying his best to breath through his nose even as his throat began violently rejecting the slab of cockflesh blocking his airways. As the trembling of his body began to slow and his vision darkened around the edges, Midoriya pulled Jiro away leaving him coughing and sputtering as he desperately filled his lungs with air. Two circles of purple lipstick were left on Midoriya’s cock after pulling Jiro off of it, one on his tip and the other at the point where Jiro’s throat blocked any further progress with a large smear connecting them. “Is that as much as you can take?” He asked, both to keep up the bizarre role of a dominating stud he found himself in as well as genuinely asking if Jiro couldn’t go any further.

After several deep breaths, Jiro looked back up at him. “I… I told you… I’m tougher than I look…”

“Yeah, you did.” With no fanfare or warning, Jiro was forced back onto the slab of meat back down to the halfway point. Unlike last time, Midoriya didn’t stop there, forcing Jiro down to the base of his shaft whether he was ready or not, inch by agonizing inch. And Jiro loved every moment of it. “Almost there…” Jiro took it better this time, the lack of air still burned his lungs but his body had learned to accept Midoriya’s cock filling his throat. “It’s a shame you aren’t wearing that choker from your Hero costume. I’d love to see how far down on my cock I could force you before it snapped.” Jiro had no doubt it would. His throat was already stretched to it’s limit, that piece of fabric wouldn’t last long. “That’s an idea, get a replica of your costume to fuck you in, see how long you can keep up that tough act before the horny little bitch you are shows through.”

With one last spenditure of effort, Midoriya forced Jiro down all the way on his dick and brought the punk’s nose against his pelvis. Jiro’s arms hung limp at his side, the only thing keeping him from collapsing being the hand gripping his hair and the cock jammed down his throat. “Such a good girl, taking it all.” Jiro felt his dick twitch at the praise, but it would be absolutely nothing compared to the pleasure that was about to come. “But that’s just the beginning. Now comes the fun part.” All at once, the twink was pulled from the base until just the tip sat in his mouth. Before he could even register how empty his throat now felt without Midoriya’s cock filling it, he was forced back down in just as swift a motion. “God your throat is so fucking tight.” Midoriya moaned under his breath as he began using Jiro’s mouth like an onahole. Slowly his entire shaft began to be painted a shade of purple as the lipstick rubbed off, looking like large continuous bruise as he pulled Jiro free to let the boy fill his lungs. As his cock flopped back onto the twink’s face, Midroya looked into his one visible eye. “Still tough enough to keep going, slut?” Jiro didn’t respond, but the needy look he got instead was all the answer he needed.

Some time passed like that, periods of intense face-fucking broken up by the occasional break for air. Jiro couldn’t tell just how close Midoriya was to finally releasing a load straight into his stomach, but the thought alone gave him the energy to keep together under the brutal assault. Somewhere in the haze, Jiro recalled trying to bring a hand to his abandoned shaft and relieve the building arousal, only for a strand of Blackwhip to force both of his hands behind his back. “Did I say you get to play with yourself?” Midoriya growled as he slammed Jiro’s face against his crotch, holding him down until his throat began spasming once more as punishment. “You either cum on my dick, or not at all!” Jiro never tired to reach for his tiny prick again.

If lapping away on Midorya’s rod was a seemingly never ending bliss, being skull-fucked like this was the pleasure of hours condensed down into what seemed mere moments to Jiro, fading in and out of lucidity as degrading words filled his mind while steel-hard cockflesh stretched and abused his throat. For as much stamina as Midorya seemed to have though, even he had his limit. Jiro began to hear his grunts grow more and more ragged and the act of forcing him up and down his shaft became a jerky, desperate thing. “Fuck… so close…” The twink wrapped around his cock didn’t need the verbal warning, the twitching and throbbing was clue enough. Drudging enough effort to look up at the lust-driven beast wearing Midroya’s skin, Jiro gave the closest thing his exhausted self could to a pleading look, begging for the load that was coming.

“You want my cum so bad?” Midroyia asked, getting the slut’s meaning, “Then you… can… fucking… take it!” Each word was punctuated by slamming Jiro’s face against his crotch before a torrent of cum flooded down the slut’s throat, the twink’s own cock spurting a weak load between Midoroya’s legs and landing forgotten on the floor. Rope after rope pumped into Jiro’s stomach and soon cum began spurting from the sides of his mouth and out his nose, nearly drowning him in jizz as his stomach bloated. As he came, Midoriya slowly pulled Jiro from the base of his cock until just the tip was sitting in his mouth giving him a full taste of the thick, gooey cum Jiro was now hopelessly addicted to. Once Midoriya’s orgasm finally petered out, he let go of Jiro’s hair and pulled away. Despite the protests of his worn body, Jiro resisted collapsing just long enough to show Midoriya an open mouth full of cum before gulping it down, showing off the now clean orifice like a pet begging for a treat. Earning a “Good slut” from Midoriya, Jiro finally let his body go slack and collapsed against the edge of his bed, staring up at the man who reduced him in such a state.

For as utterly worn and used as Jiro felt, Midoriya only looked like he had just taken a light jog around campus, the sweat soaking into his color and matting his hair the only signs he was anything but at his peak. Jiro however was a wreck, the blazer of his commandeered uniform only had a single button still fastened, both it and the shirt underneath it disheveled and stained with a mixture of spit and cum. His makeup was ruined, mascara tracks tailed down to his chin while his lipstick was reduced to a vague smear around his lips. Were it not for the small bulge of his dick visible underneath the green skirt and the stain centered on it, anyone would have been forgiven for mistaking the boy as a worn-out prostitute left discarded in an ally after being used and abused. That thought alone sent a jolt of arousal down Jiro’s spine.

It must have been just as arousing to Midoriya to see his handiwork. Jiro’s eyes shot wide in a mixture of horror and lust as the cock that had just violated his throat rehardened, towering over him with a promise of even more furious, rapid sex in his imminent future. “Don’t look so surprised.” Midoroya palmed his cock in long, deliberate strokes, more to rile Jiro up further than for his own pleasure. “Did you really think I’d be done after one load? No, were going to be busy all night.”

All night?’ Jiro went stiff before slowly craning his neck to look at the clock on his night stand. It had been nearly an hour since since Midoriya had come into his room. And here he was, a broken mess of a slut barely able to breath. Could he even last a full night, or would his mind shatter under the marathon of relentless, savage fucking Midoriya promised?

Did he even want to stay whole?

“Well?” Jiro breathed out with all the traces of his usual confidence he could muster as fucked ragged as he was. “Gonna… fuck my throat… inside out again? Or are you… gonna move on… to the hole you haven’t… claimed?”

“Claimed?” Midoriya barked out a laugh before grabbing Jiro by the wrist and dragging him back up to his feet. Positioning the slut in front of the mirror with an arm around his neck, Jiro had a full view of just what Midoriya had done to him and the perfect spot to watch himself break apart. The verdanette flipped up the back of Jiro’s skit and positioned his cock at the entrance of his ass, prodding and teasing the slut. “I don’t need to claim anything. You gave yourself to me the moment I walked in this room. No, the first time you thought about me rearranging your guts. Now I’m just here to use what’s mine.”

With all his might Midoriya rammed his cock to the hilt in one swift motion, the force of it sending Jiro off the ground and into the air as his virginity was taken from him. The air was forced from his lungs in a strangled, pitiful gasp, but Jiro doubted he would even have screamed with his thoughts overwhelmed as they were by both the pain and pleasure erupting from his ass. As the sound of flesh meeting flesh began to fill the room and Jiro adjusted to the new feeling that was having his ass forcibly violated, every ounce of breath was forced from the twink’s lungs as soon as they could draw any scrap of air. Barely staying on the tips of toes as his body was rocked with the full might of Midoriya’s unyielding sex drive, Jiro felt himself go limp in his dominator’s arms and his eyes glazed over, locked onto the sight of the purple-haired slut in the mirror overtaken by a rapturous bliss.

“Look at you. Does that look like some damsel that got claimed by a dashing rouge like Momo’s novels? No, you gave yourself up to the man who could fuck you into a wreck without a second thought.” Midoriya breathed in Jiro’s ear, relishing the way the boy tightened down on his cock with every slanderous word. “You know why?”

“Be-ca-au-uh-uh-se I-i’m a slu-uh-uh-uhhht!” Jiro moaned out, his words threatening to fall apart with every thrust driving the air from his chest. Midorya paused as he nearly pulled himself free of Jiro, raising up his free hand before bringing it down on Jiro’s bare ass with a slap that would have been heard through the entirety of the dorm’s were the room not soundproofed.

Jiro screamed, and the reddening hand print stung like new every their hips collided as Midoriya began fucking Jiro with renewed vigor. “Wrong! You’re my slut, got it? No one else gets to use you like I do, because no one else can fuck you like I do!” With a few slower, more forceful slams, Midoriya drove the point – and his cock – home. “I own you! Whenever I want, you’ll let me bend you over and fuck you like the whore you are! If I so much as ask, you’ll be on your knees worshiping my dick like it’s the only thing in the world that matters!”

He was right, there was no point in denying it. Jiro was hopelessly, painfully aware he could never go back to the life he lived before experiencing Midoriya’s cock. It didn’t matter if it was in public, in front of their class, in front of his own parents, the second Midoriya told him, he’d throw away every shred of dignity and show the world the desperate cockslut that had replaced the Hero Jiro Kyoku.

“Yes!” Jiro shouted. “Fuck me! Any time you want, you can fuck me! I won’t stop you, I know I couldn’t stop you! I’ll suck you off before every patrol! After too! Fuck, I’ll give up being a Hero so you have a cock-sleeve always waiting for you at your agency! Just… please, don’t stop fucking me!” If he really meant it or was just spewing whatever lust-driven thought came to mind, not even Jiro knew, but at the moment it sounded like nothing but the pure, honest truth.

The arm across Jiro’s neck loosened, but before he could fall the slut’s face was grabbed by the chin and pulled to the side. Midoriya’s lips met his, the verdanette so consumed with need he didn’t even care where Jiro’s mouth had just been. His tongue forced Jiro’s lips apart, dominating the punk’s mouth like his cock dominated Jiro’s ass. The twink didn’t bother to put up the slightest amount of resistance, instead moaning and sucking on the new intrusion as his new master marked his ownership of Jiro’s body and soul both.

Pulling away to catch his breath, Midoriya replaced the arm around Jiro’s neck. “Such a good slut” He moaned into Jiro’s ear, the insult feeling far more like a term of endearment by now to the both of them. “Maybe I should make it official. Buy a cage to lock up that pathetic excuse of a cock for good, so the only way you ever cum again is on mine.” The thought alone was enough to push Jiro over the edge, his body clenching as ropes of cum shot out onto the mirror in front of him and spilling over the floor as he let out a strangled moan.

Midoriya paused, taken aback from the intensity of Jiro’s reaction. “Is that what you really want? To be reduced to nothing but a hole for my dick? Maybe I should get ‘Property of Deku’ tattooed across your ass too.” There was no response from the twink, his head hanging low and his breathing ragged. If it weren’t for the pitiful moans asking for more under his breath, Midroyia would’ve thought he fucked Jiro into unconsciousness already. His free hand came up to Jiro’s hair, yanking it back to force him to look at the mirror now painted with streaks of his own semen. “Look at you. Look at the slut in the mirror, covered in cum just from the idea of having his dick locked away to get fucked in the ass for the rest of his life!” Jiro obeyed, looking to see exactly what was described. “All it took was one night to turn you from a Hero to a helpless, moaning, piece of fuck meat. Although, there is once thing wrong.” Jiro perked up at that, looking to his owner in desperation. All his drive to become a Hero or musician long since replaced with a need to become the perfect slut in every way. “You’re not soaked in cum like that slut in the mirror. So let’s fix that.”

Jiro’s heartbeat picked up, eager for whatever would happen next as Midoriya brought him over to the bed and all but threw him on it. Without waiting or asking, Midoriya grabbed Jiro’s ankles and brought them up to his head. Lining up his cock, Midoriya positioned himself in a mating press only pausing to savor the sight of Jiro trembling underneath him. The bed underneath them creeked and threatened to fall apart the moment Midoriya began spearing Jiro on his cock, and the slut’s moans filled the air as he was fucked into the mattress. Even as drained as he was from the most intense orgasm of his life not even seconds ago, Jiro began leaking like a faucet over his face, chest, bed, and even the wall behind him.

“O-o-oh my gah-ah-ah-ahd!” No choice but to stare up at the man rutting into him, Jiro saw Midoriya’s expression morph into one he only ever showed in Heroics class or on patrol. A determined glare normally reserved for taking down villain’s and rescuing civilians, now being worn as he fucked Jiro into submission like it was the most vital of missions. “C-uh-uh-uhmi-i-i-ing!” A large squirt of seed from Jiro’s flopping cock hit his own face, forcing him to close an eye. This wasn’t sex. This wasn’t even anything like Midoriya using him as a sex toy to get off. He was breeding Jiro, and the slut was in love with every second, every single thrust, and every time a vein of Midoriya’s cock scraped against his prostate. He only regretted that he couldn’t actually get pregnant, not that it seemed to deter Midoriya any. Maybe there was someone with the right quirk out there that could fix that?

“Who owns you?” Midoriya shouted down at him, only to receive silence as Jiro failed to respond. “I said who owns you, slut?”

“YOU!” Jiro wailed back, his voice tapering off in a whine as the breath was fucked from his lungs. “You own me! Now and forever! I belong to you, to your cock! I love it! I love you! Because you know how to put me in my place! Because you know what I am! A slut for your perfect fucking dick!”

The confession from Jiro sent Midoriya rabid, emerald sparks dancing off his skin as he used the power entrusted to him by All Might for defending the innocent to fuck his classmate senseless. Jiro’s eyes rolled to the back of his skull, every thought beyond pleasure and lust driven from his melting brain as he desperately clung to this side of consciousness. Bringing a hand to Jiro’s chest, Midoriya ripped open the blazer and shirt in one motion sending buttons flying off in random directions. The skin underneath was paler than Jiro’s already pallid complexion, the near total lack of muscle on his frame allowing the bulge of Midoriya’s cock as it filled him to show all the more clearly.

Jiro’s tongue lolled out from his mouth, and Midoriya felt satisfied in finally doing what his lower head had demanded he do when he first saw Jiro in that compromising position. It wasn’t a moment too soon, as he felt the familiar tension build in his pelvis that meant his release was not far off. Too focused on rutting the boy beneath him and said twink too broken to even notice any sensation that wasn’t the cock ruining his ass, Midoriya didn’t bother announcing it, simply pumping away through his orgasm and watching Jiro’s stomach bloat out. Releasing one of Jiro’s ankles to grab his loose jacks in one hand, Midoriya pulled to bring his dazed face up for a target before pulling out and painting Jiro’s face and bare chest white. Straightening his back out and taking a deep breath, the last dredges of Midoriya’s orgasm slowly dipped from his tip and fell onto Jiro. He let go of the jacks in his grasp to let the twink’s head fall back onto his pillow and stole a glace at the clock beside it. Just after 10pm.

Maybe not technically all night, but even if he still had more in the tank Jiro most certainly didn’t. His shoulder’s rose and fell as he panted, the lust pushing him fading with weariness coming in to replace it. The thought of returning to his room was looking more unappealing by the second, and sleeping in the same bed was tame after he had just turned said bed into an alter of depravity to finalize Jiro’s baptism as a cock-worshiping whore. Collapsing next to Jiro, Midoriya turned on his side to pull him closer, uncaring of the jizz soaking into his shirt. “Such a good slut…” He whispered into Jiro’s ear, feeling one last shudder rack Jiro’s body before he fell into a deep, blissful sleep.

 


 

Midoriya came to slowly, a deep exhaustion unlike any workout he could recall urging him to stay in the warmth and saftey of his bed. Although, he didn’t remember his bed smelling so odd, and the wet, sticky feeling on his chest was certainly unusual. Weirder still was the warm bundle in his arms that sounded like it was breathing…

Opening his eyes a crack to the sight of purple streaked with white, a brief moment of confusion ran through Midoriya’s mind. Only as Jiro’s eyes did the same and met his did the memories of last night come flooding back. Jiro’s hazy comfort was soon dashed as well, the two of them staring at each other in shock, but neither moving away from the other. “H-hey…”

“Hey…” Jiro parroted.

“So… last night…”

“Yeah, that… happened…” He breathed out, still clearly tired even after a night’s sleep.

“How are you feeling?”

“Green, my throat is killing me, I’m not going to sit right for a week, and I can’t even feel my legs. I feel like shit.” Before Midoriya could apologize, Jiro cut him off. “And it was so. Fucking. Worth it.”

Midoriya let out a relieved chuckle. “Well, I’m glad.” For few moments, the two lied there in each other’s mutual warmth before Midoriya hesitantly asked. “So… Jiro-”

“Kyoku.” He cut off. “After last night, I think we’re way beyond given names.”

“Right. So… uh, what are we?”

Jiro tilted his head at the question. “What do you mean?”

“I mean, well… we had sex, and I want to do it again, but are we just like, friends with benefits or…”

“Oh my god.” Jiro tried and failed to stifle a laugh. “You rant about how you ‘own me’ only to turn into a blushing mess the day after?”

“I wasn’t thinking straight!” Midoriya defended himself, unaware of the pun he just made. “I got caught up in things and… kinda said some stuff.”

“Well keep ‘saying stuff’ like that next time, Green, because that was fucking hot. But yeah, if you want to be more than just fuck buddies, then I’m all for it. Going on a date and then being fucked into the floor right after sounds like the perfect day.” Jiro leaned in for a kiss, and Midoroya could still taste both his own and Jiro’s cum on the boy’s lips. It was little more than a peck on the lips compared to their sloppy make out while one was balls deep in the other, but it sent his heart fluttering in joy at the fact he had a boyfriend now.

Pulling away, Midoriya sighed in contentment. “Well, it’s Sunday but… I don’t know if I’m feeling up for a date. I just want to laze around after last night.”

“But, what about what you said before?” Now it was Midoriya’s turn to be confused, prompting the punk to continue. “You know, how you said you’d… go buy a cage and…” Too embarrassed to continue without lust and hormones to remove any traces of shame, Jiro trailed off as Midoriya’s eyes widened.

“Jiro I… that was just dirty talk.”

“Y-yeah. Of course!” Jiro nervously laughed, convincing neither of them. “I knew that.”

Midoriya felt his lips curl into a smirk. Grabbing Jiro’s ass as he pulled him closer and earned a girly sequel for the effort, he leaned in to whisper into his boyfriend’s ear. “Well if you think it’s such a good idea, then why not?”

“I…” He stammered out, before pushing himself to sit up. “I need to take a shower! But… yeah, we can… do that…”

With a full body stretch, Midoriya matched the posture. “Why don’t I join you? I doubt I can go back to my room like…” Only now did Midoriya finally have a full understanding of just how badly they had ruined the room. Jiro’s clothes were missing several buttons and beginning to tear at the seems, while his bed, floor, the mirror, and the walls were covered in dried cum. Even the plate of now-stale curry was spilled out near the door where it had been forgotten. “Shit, did I really… I’ll help you clean up. And, sorry about your clothes.”

“Don’t worry about it. I’ve got a few sets. Sometimes it’s a while before I can wash them without anyone noticing so… I made sure I have enough.” Swinging his legs over the side of the bed, Jiro forced himself to stand with great effort, his steps shaky and unsure. He looked back, not daring to meet his lover’s eyes. “Um… can… I get a bit of help getting to the shower?”

“Of course.” With much more stable footing, Midorioya help guide Jiro to the bathroom where the two washed off the filth of the night – but not before Jiro fell to his knees in the shower and made some more filth to clean. As Jiro began pulling out every single cleaning chemical and air freshener he had, Midoriya stepped out of Jiro’s room clad in only a towel to stop by his own, get dressed in clothes that weren’t reeking of sex, and come back to clean up.

Only to stop as he saw Mineta in the middle of the hallway, the case for his Hero suit in hand.

For an instant the two simply stood in stunned silence as Midoriya’s brain worked overtime to try and craft a convincing explanation for why he had just emerged from Jiro’s room all but naked, only for Mineta to break the silence. “So… you and Jiro, huh?”

“Y-yeah…” He gulped. “Why are you…”

“My work study went late, so I slept at the agency.” His eyes drifted to Jiro’s closed door. “But still, best news I’ve gotten all year.”

Midoroya was taken aback. “Uh… why?”

“Because not only is Mr. ‘Shoo-in for Hottest Hero’ taken, but so is the edgy bad-boy punk.” Midoriya did everything he could to not smirk, wondering just how Mineta would react if he knew exactly what got the ‘bad-boy’ going. “My chances of scoring just went up!”

“Yeah, sure.” Midoriya said, not convinced his new relationship would have the slightest impact on Mineta’s own love life. “I’m going to go get dressed now.”

With a nod Mineta walked back to his room, only pausing to look over his shoulder as he opened his door. “Congratulations, by the way.” And slipped inside. Now alone, Midoriya could only sigh, wondering just how long this new development would stay under wraps before the whole of his class found out.
