Work Text:
There’s a throb between his legs that makes him want to rock against the edge of the chair, but he’s not about to. The doctor’s trying not to meet his eyes, steadfastly staring at his monitor.
“The quirk's effect should wear off in about 24 hours,” he’s saying, “I’m putting you on medical leave, but if you’d like I can also prescribe some soporifics. To-to take the edge off.”
He’s sneaking a glance, this fucking small fry mob doctor his agency sent him to.
“Fuck if I need that,” he says, and to his satisfaction the doctor’s face flushes beet red.
Back at his flat he can’t get out of his clothes fast enough. Just the pressure and friction of the fabric is driving him insane. Getting in front of the bathroom mirror he finally gets a good look at himself. It’s almost like his mother’s face looking back at him, the angles smoother, the proportions gentler, but the eyes are still the same, his. He’s still got muscle, but his body’s softer, rounder. He touches his chest and the pink nipples knot and darken, and the touch goes straight to his crotch with a jolt. Looking down to where his dick should be there’s nothing visible through the hair, but he can feel it down there, between his legs. He sticks his hand down, angling toward the throb, and just a light touch almost makes his knees buckle. His fingers are wet and slicker than oil. He knows it’s the quirk effect, but still has to wonder how women walk around with this thing in their pants every day and not go crazy. Well, he thinks, and washes his hands in the sink, nothing to do but get to it.
It shouldn’t be that hard, he thinks. The theory remains the same, you find where it feels good and then just keep at it. With how sensitive his new pussy is, it should be so easy to make himself come, but two hours in and his wrist is killing him and his whole lower body feels clenched and heavy. Who the fuck knew women could fuck themselves up by jacking off and not being able to come. He’s been able to get himself close so many times, but just almost. Just when he could feel the peak coming, he’d mess up the rhythm, or direction, or speed, or amount of pressure, and suddenly he’s floundering and the same touch that had just nearly gotten him over the edge doesn’t feel the same anymore. He’s tried teasing his clit, and it feels incredible but it’s not getting him there. He’s tried sticking his fingers in. Three fingers fills him up and feels so good, but if he could just get in deeper, maybe he’d make it. Both at the same time is the best and has gotten him closest, but it’s still the same. Just as the wave is about to break over him, it recedes leaving him aching and frustrated. He’s tried porn and he’s read masturbation guides in cursive on some pink, frilly sites. Nothing works but his pussy is demanding that he try. If only he had his dick, he thinks, and with that the solution’s suddenly so obvious. He grabs his phone and thumbs out a message.
Get over here
He looks at the message and since it’s not read in the first five seconds he figures the tone is not quite urgent enough.
NOW!
Before the doorbell finally rings he’s tried his left hand and found it equally useless. He briefly considers throwing something on, but his body’s so sensitive he decides against it.
Deku actually screams. He throws his arms up and is about to bolt so he just grabs him by the collar and drags him in.
“Shut up, you’re bothering the neighbors!”
Deku’s still got his arms over his face and he’s wedged in the corner against the door. He’s mumbling, and he suddenly gets it.
“It’s me! It’s fucking me!”
Deku lowers his arms a bit and gingerly opens one eye. “Kacchan..?”
“Yeah it's me,” he says, crossing his arms and immediately regretting it as his breasts react to the touch.
“A quirk accident?” Deku’s voice is trembling.
“Yeah,” he says. Now that Deku’s got his eyes open he’s keeping them glued to his face, and it’s making him uncomfortable.
“So you get why I called you here?” he asks, and Deku blinks, his eyes wide with shock.
“It’s your graduation day,” he says, and it shouldn’t make him excited because that’s just gross, but between his legs he’s dripping wet.
“Get your pants off,” he says, making a grab at Deku’s belt, and he has the audacity to jump back.
“Wait wait wait!” Deku’s looking like a deer in headlights.
“You saying no to me?” he snaps, and if anything Deku looks even more panicked at him raising his voice. “No, I just- shouldn’t we shower or something first?” he stammers.
He thinks Deku’s most likely playing for time, but then again it’s true that he’s sweaty from exerting himself, and his pubes are matted and clumped together. Maybe even nerds require a bit of romance.
“Then you go first,” he tells him. “And leave your clothes there.” He’s not about to let Deku slip out while he’s in the shower.
It’s going to be graduation for them both. He’d never would’ve thought his first time would be with Deku, and certainly not like this. Strangely the idea doesn’t bother him that much. Maybe with quirk accidents it doesn’t count, or at least to him. It’s not even his own body.
He finds Deku sitting on the edge of his bed, mumbling to himself. This is what’s so scary about the nerd, that he’s been doing research, that he’s probably running simulations in his head right now. He’s even tenting the towel around his waist.
“I don’t have any condoms,” he says, like he hadn’t been screaming and stuttering just a moment ago.
“It’s a convenient quirk effect,” he tells him. He’s glad he listened to the doctor to learn this tidbit. “There’s no reproductive function.” He grins. “You know what that means.”
He’s seen Deku's dick a million times, ever since they were kids and through UA’s shared baths, but it occurs to him only now that he's never seen it hard. Granted, he hasn’t seen any but his own in real life, because porn doesn’t count, but it’s still a surprise. It’s bigger than he might have imagined if he’d ever given it any thought, certainly thicker. The quirk effect’s messing with his brain because it makes his mouth water. He spreads his legs before registering that he’s doing it. The wet folds open and the cool air makes him shudder. He’s expecting Deku to just put it straight in, but instead he gets down between his legs and puts his mouth on it. Fuck. It’s like fingering the clit but so much better. Deku’s running his tongue around the lips, over the clit, dipping it inside. His ass is off the mattress as he’s pushing up to meet him. Deku cups his ass in his hands and eats him out in rhythmic strokes. A finger pushes inside, searching, and just one isn’t enough is what he’s about to think when it crooks inside him and finds a spot he hadn’t. He bucks without meaning to and loses the feeling for a second, but Deku’s licking and fingering him and he’s back in the game. He knows the feeling by now, the climb toward the peak, even if he hasn’t gotten there yet. If he could think straight he might take some pointers, but there’s no capacity for anything besides feeling good, and better, and even better. His skin sheens with sweat and fireworks go off behind his eyelids as his body arches off the bed. It’s nothing like coming from stroking his cock. It’s a hot wave washing over him, a release of pressure he didn’t even notice building this time, leaving him feeling boneless and out of his body.
Deku’s muttering something under his breath as he’s climbing on top of him. He’s obviously trying to figure out how to prop himself up while lining himself up with one hand. Coming down from his peak he’s a little nervous about the real thing after all. Deku’s cock might be thick, but he’s had three fingers in already so he should be fine is what he’s telling himself as he feels himself stretching from the pressure and belatedly realizes his hands are not his broad male hands. He’s gasping around Deku, his whole consciousness concentrated on the hot pressure, and suddenly like a kaleidoscope bursting into a new pattern the pressure feels good. He’s in so deep, and when Deku grinds against his clit he’s seeing white.
“Harder,” he grunts, but in her voice it comes out a breathless moan.
The bed heaves as Deku drives into him, the headboard slamming into the wall with a crack. Deku looks up, startled, and starts to clamber off him.
For a moment he thinks Deku might abandon his post, but he gets his knees under himself and pushes back into him, somehow getting in even deeper. He’s trying to bring his knees up but Deku pushes them open with his elbows, grabs him by the waist and fucks into him, fast. It’s so different from the rhythm he had gotten close with he thinks it shouldn’t feel good, but it does, and the climax takes him completely by surprise, punching the air out of his lungs. His whole body clenches like he’s electrified, and a pulse of pleasure explodes inside him. He claps his hands over his face, startled, not knowing what kind of face he just made. Deku thrusts a few more times and groans above him. He keeps his hands over his eyes while Deku pulls out, trying to figure out if he should have felt him come inside him.
“Sorry Kacchan,” Deku mutters and rolls him over to his stomach. He’s being pulled up and when he peeks he’s shocked to see Deku’s hard again. It feels crazy, seeing and feeling the cock push up into him at the same time, and maybe he’s crazy but he reaches his hand out and splays his fingers around it, feeling himself opening up to it. Behind him Deku sucks in a sharp breath and slams against his knuckles and grinds in, hard. Deku’s coming but neither of them stops. He brushes his fingers over his clit and he’s already coming too, his back arching up. Deku only slows for the moment he’s tightening around him, and continues. Deep inside him a muscle he didn’t know he had contracts and releases. His breathing’s so loud it almost drowns out the steady wet slap of their bodies against each other.
Deku’s thumb passes over his asshole and it’s like lightning shooting up his spine and his head snaps back so hard it almost gives him whiplash. He’s done his bit of experimenting, and playing with his ass had been part of it, but in the end he never really got the appeal, and he didn’t see the point of putting in the work in prepping and cleaning when you could just rub one out and get to sleep. But if it had ever felt like that he might have reconsidered. He’s trying to breathe and swallow and neither is going like it’s supposed to. Deku’s fucking deep into him, and his thumb comes back around, circling the hole. This is what he both hates and admires about him, that for him everything’s a learning experience, that he’s always testing the boundaries. There’s a pressure that’s building up inside him, like an itch, and it feels like it’s holding him back, and he wants to let it go. A woman is moaning and crying and it’s him, and Deku’s thumb pushes into him and the pressure releases like a dam bursting. The woman screams and he blacks out from coming.
When he comes to, he’s on his back and Deku’s between his legs wiping him down with a hand towel. His pussy’s throbbing and he doesn’t know if it's a sore throb or a needy throb. He’s having trouble focusing, but then his hand touches a wet spot and the dots connect painfully, a row of dominoes cascading into a realization. He claps his hands over his eyes.
“Did I fucking piss myself?” he asks, and his voice sounds too small for how mortified he feels.
Deku looks up at him, embarrassed.
“No, I, um, I think you probably ejaculated,” he says.
He lets that sink in and releases the breath he was holding. He doesn’t really get it but apparently he hasn’t done something he’ll never live down. He lets his hands fall. Deku’s trying to mop the bed, his hard-on bobbing around between his legs. So maybe he’d pulled out when he dropped and hadn’t finished. He’s not sure where to go with that line of speculation. His pussy pulses and it’s definitely a needy pulsing now, but he’s also curious. It’s the quirk effect and it doesn’t really count, and when is he going to have another opportunity like this. He chooses not to focus on the fact that he shouldn’t be thinking of a quirk accident as an opportunity in the first place.
“Want to try that next?” he asks, choosing to look at Deku’s cock instead of his face.
Deku splutters, but doesn't his cock seem to get darker.
“I want to try it,” he says, and the cock pressed against his thigh is hot and ramrod hard. He looks up at Deku’s face, and while he’s flushed red his expression reminds him of the UA trials.
Deku’s working him with the patience of a nerd, and while it feels good, he wants more. He doesn’t know how many fingers are scissoring inside him, but he feels ready. He snakes a hand under and touches himself, and at that there’s a choking breath behind him, and Deku pulls his fingers out. It’s on the side of uncomfortable, the pressure of being stretched open, but he’s expecting the turn and that makes it delicious. He’s pushing off the mattress to meet him, and after the initial pressure he slides in balls deep with relative ease. Deku thrusts slowly, carefully. His pussy is drenched under his hand and two fingers slip in as if guided. He doesn’t get in as deep as he wants, but just fingering himself while Deku’s in him makes him see stars.
He’s getting fucked limply into the mattress, and the friction of the sheet makes him come while he’s still reeling. Deku slams in and freezes, groaning, and the next thing he’s panicking and stuttering again.
“Kacchan, I’m so sorry! I honestly didn’t mean to!”
It takes him a beat for it to dawn on him that Deku’s come in him. He doesn’t really get what the big deal is, it’s what he told him to do. If he can’t get pregnant from his pussy then he’s definitely not getting pregnant from his ass, but for Deku to get this distraught there’s gotta be some significance to it.
“Worry about that after you fuck me again,” he mutters, and Deku drags his ass up and pushes into him and he’s content letting his mouth hang open and eyes roll back because it feels too good for words.
Hot cum drools out of his pussy and down his leg and Deku cups a hand under him with a look of abject concern. He lets himself be walked to the bathroom, lets Deku wash out his ass while clinging to him in the shower, lets Deku fuck him twice against the shower wall and once bent over the washing machine before letting himself be walked back to the bed. He’s so sensitive he’s coming as soon as Deku’s in him, slick with sweat and the sound of his female voice moaning so familiar it barely even registers in his mind anymore. He’s trying to watch the cock pumping in and out of him but can’t even keep his head up. Deku’s sucking and twisting on his breasts, and each pinch and bite is going straight into his crotch. He’s feeling the pressure again, and now he knows how to release it. He squirts all over Deku’s stomach, and the hot droplets spatter across his heaving chest. Deku looks down, eyes half-lidded, runs his hand over his wet stomach and puts his fingers in his mouth. He can feel himself twitch and tighten, and then he’s coming, arching off the bed.
He wakes up himself again, with everything where it should be. There’s a dull ache deep inside him, an echo of the soreness he’d be feeling if he still had his female body. His nipples are tender and his ass feels like there’s still a cock in there. He huffs out a laugh. Beside him Izuku stirs and blinks his eyes open, and as soon as he does he's up.
“I’m sorry Kacchan, I’ll get out, just- I’m so sorry!” He’s apologizing and panicking, frantically trying to look around for his clothes, not remembering where he took them off. He supposes it’s a little funny.
“Where do you think you’re going,” he asks, and Izuku freezes.
He spreads his legs, and the cool air makes him shudder. Maybe he’s still out of his mind.
“I haven’t graduated yet.”
