A/N: yeah ik this isn't what i typically write but idk where this came from. i had a thought and it spiraled bad and now i have this. there is no deeper message. there is no meaning. i wrote this to make him FUCK and be kinda weird and desperate and pathetic about it. i needed to see him physically overpower us while also so desperate that it makes him look stupid. i feel violent. this bad boy is not going on ao3 lol. anyway, enjoy, heed the warnings.

Katsuki paces around the one bedroom apartment he rents in downtown Musutafu. His skin is tingling. Every nerve he has burns like it's been set on fire, needing some sort of touch to soothe it. His cock aches between his legs, hard and leaking against the side of his thigh. Katsuki grits his teeth, running his hands over his hair and then letting his palms slide down the sides of his exposed biceps.

Sweat collects on his skin, the kind that comes from desperation or maybe a fever, and he feels it on his palms when he lets them drop to his sides and clenches his fists. Fuck, he can't believe he got hit with a non-fatal quirk and had to be sent home. It's humiliating. What's worse is that it hasn't worn off yet, rendering him completely useless.

He sits on his couch, his legs spread wide, and leans back against the couch cushions, wincing as he reaches to unbutton his pants. He's never been this sensitive in his life and it almost hurts to grab his cock and pull it from his pants. Katsuki watches it twitch for a moment, rigid between his legs and leaking pre-cum from its angry tip. He doesn't even have to think about anything in particular, he's just turned on. Unbearably so.

Katsuki wraps his hand around the base of his cock and jerks upward once, sucking in a sharp breath through his teeth at his own sensitivity. Then, the desperation sets in fully and he squeezes the head of his cock with a wince and a low groan before beginning to slide his hand up and down. He pauses to spit into his palm, desperate for some sort of relief from the tension weaving its way through his body, his hand moving faster and fast over this dick. Katsuki only pauses when he touches his overly sensitive head, swallowing down an audible moan as he moves his hips to desperately fuck his fist.

He tries not to think of the humiliation in this, instead focusing on chasing a high that seems to get farther and farther. He stays like this for a while, desperately fucking his fist with low groans and whines. His face is completely flushed, sweat beading on his brow and forehead, covering every inch of his skin with a pathetic, glowing sheen. God, he's almost fucking angry. The frustration, the sheer desperation for release, is making it difficult to control his temper and he knots his free hand into the soft pillow beside him, raising it to his face and using it to cover his head so he can be a little louder.

He's desperately humping his fist when his doorbell rings. At first, it's only once and Katsuki thinks he can ignore it, but then it comes again, five more times and consistently more aggressive.

"Katsuki?" your voice calls through the wood paneling of his door. "I heard you got hit with a quirk and sent home. Let me in."

He furrows his eyebrows at the irony of the last person in the world he wants to encounter at a time like this. Pretty, quirkless, you. His long time friend and recent dispatcher at his agency. Someone he secretly wants to fuck even without the aphrodisiac quirk floating through his bloodstream. You really get under his skin. You’re exactly his type, right down to that annoying little attitude of yours that drives Katsuki insane. Of course, he's always respected your friendship a little too much to do anything about it, but tonight, he doesn't think he'll be able to and he sits in silence with his lip caught between his teeth while he fucks his fists and hopes you'll go away.

"I know you're in there," you call again. "I can see the light on."

You bang three times on the door and then ring the doorbell again, pushy and insistent the way you always are. A match for his stubborn attitude.

Katsuki swears and stands up, his hands shaking as he tucks his sensitive cock back into his sweatpants and flips the head up into his waistband with a hiss.

The crazy thing is, he can literally smell you through the door. The scent of you, that sweet and rounded perfume you wear, wafts under the crack of his apartment door. He pauses outside of it, resisting the temptation to open it, to welcome that smell into his apartment and use you to relieve the aching in his cock and lower belly.

"Katsuki?" You ask, a little quieter now.

Jesus fucking christ, don't call his name like that.

He swings the door open, letting his hand rest on the side of it so that it is positioned above his head. You look taken aback at his appearance, covered in sweat and flushed from the neck up, his chest exposed and heaving.

"What?" he says, looking you up and down.

Katsuki bites back the urge to yank you in. Why is it he can literally smell the sweat on your body and every prick of your emotions? It's like he can tell exactly what you're thinking, or maybe it's what he wants you to be thinking.

"Don't get on my ass about me still technically needing to be at work," you start, stepping forward. "I heard something happened and I just came to check and you look like shi-"

Katsuki blocks you from coming in with his body. You stumble backwards lightly and raise your eyebrow at him. There's a pause as you register that you've just run into a solid wall of muscle, sweat covered and glistening, while Katsuki eyes you like you're meat on a platter. He knows he's doing it, but he can literally smell every turn of your scent, soft and sweet. And he may be fooling himself... but are you... turned on?

"Let me in?" you say with a small laugh, side stepping to go around him. He blocks you again, his fingers gripping the door frame so hard that his knuckles are white.

"Go home," he says quietly, his voice tense.

"What? No," you furrow your eyebrows at him. "What's the matter with you?"

You duck under his arm and place your hand momentarily on his chest. Your touch makes him tingle all over and he sucks in a sharp breath.

"I'm not fucking around," he says.

"Okay, me neither," you respond with a bit of an attitude. "I expected you to be worse for wear but you look like crap. Like you're... I don't know."

You trail off a little.

"Let me help," you say, shaking off whatever thought had come over you. "I'll make you some food."

"Look, no offense, but I don't think you want to help me with this," he says, a frustrated bite in his voice. Food isn't exactly what he's hungry for.

"That's too bad," you say slowly, seemingly put off by the desperate air about him and settling into his kitchen. You move to open the fridge.

Katsuki walks up to you quickly, taking your wrist from the door and holding it between the two of you. Cool air hits his exposed chest and arm as the door falls shut again.

"I'm dead serious. Get the fuck out of here or I'm gonna do something I regret," he hisses through a clenched jaw. Your skin is warm on the pads of his fingers, wrist held flush against his palm. He bites back a genuine shudder.

Your eyes are wide as you look back at him, glancing between where he's caught your wrist by your head and his eyes. Katsuki's gaze roams over your face, pausing as he hits the top of your blouse where a few buttons remain open. When he returns his eyes to yours, your mouth moves to open before a heady understanding settles over your features. You're so pretty. Everything about you is pretty, so delightful and delicate. Your eyes look glassy and wide. Katsuki has always found them tempting, but today he can't stop himself.

He leans forward and kisses you, holding your wrist to his chest as his mouth comes messily into contact with yours. You squeak and freeze and it takes all he has to pull away from you.

"Go home," he says again, his lips tingling. Katsuki feels the color creep onto his cheeks, his hand still holding your wrist.

You don't say anything, looking at him with those pretty eyes. He swallows thick and feels the saliva drag against his throat. Then, his mouth dries completely, his expression twisting into discomfort as his cock throbs between his legs as the scent of you takes on a sharper turn. He's never felt anything like this before, something animal.

Katsuki tightens his jaw, staring at you for a moment. Then, he takes a step towards you. You take one back, though he doesn't feel like you're afraid. Rather, you tilt your head down to look at him through your lashes. He lets out a breath through his teeth and walks you back until your ass hits the counter, his free hand coming to gingerly touch your waist. You inhale when he leans in to kiss you again, screwing your eyes shut and reaching to grab at his shoulder to pull him closer.

Every touch tingles. It burns and he drops your wrist to manhandle your hips. You suck on his bottom lip, wrapping your arms around his neck and pulling him down to you. He ruts his hips against yours, desperate for any sort of friction to relieve the ache, and you gasp a little and let your mouth fall open. Katsuki takes the opportunity to bite down hard on your lip with a low groan, slipping his tongue into your mouth as the pads of his fingers press harshly into you. You whine, eyebrows pulling up.

Katsuki’s eyes are slightly open, just so that he can look at you. Every aspect of his senses feel heightened and the relief of your mouth far surpasses that of his hand over his throbbing cock only minutes earlier.

He pants, taking your hips and lifting you onto the counter so that you’re seated, pulling away for just a moment to lift the hem of your shirt and expose your breasts. Katsuki puts his face on the pillowy tops of them, biting and sucking at the exposed skin as his hand teases its way up the skin of your back to unclasp it. He thinks you’re probably looking at him, but if you are, he doesn’t have the mind to care about what sort of behavior he’s exhibiting. He can practically smell how wet you are from just a little touching and if he weren’t so fucking desperate for a little relief, he’d tease you for a few hours just to watch your pussy drool over him.

The cool air of his apartment hits your exposed nipples. Katsuki takes it upon himself, without even a second thought, to roll the hard bud under his tongue. He feels the way goosebumps rise on your skin, his hands coming to rest over the tops of your thighs. Katsuki bites lightly on your breast and you fucking whine at it, tipping your head back and rooting your hand into the tufts of his blonde hair.

His cock jumps in his pants and he’s no doubt leaked enough to leave an evident wet spot against the gray of his sweatpants. He stands to his full height, pushing your skirt up and pressing the outline of his cock to your crotch. Heat bleeds through your panties, the kind that makes him feel like he’s going absolutely fucking insane. You gasp, putting your hands on his shoulders and pulling him close again.

Katsuki’s mouth hits yours messily, breathing hard as he ruts his hips up against your crotch, pulling you forward on the counter so he can feel as much of the pillowy folds of your pussy through the thick fabric as possible. You let him take your bottom lip between his teeth, sharp canines digging into the wet flesh of your mouth. He whines— high-pitched, desperate sound—as you position your hips to press your crotch against the head of his cock. His head falls onto your chest, forehead resting against the hollow of your throat. Katsuki humps at you, pulling you against him to match the rhythm of his hips, grinding your clothed cunt over the bulge of his cock. It’s a desperate motion, completely subconscious as he lets the quirk he’s been hit with take the lead.

His fingers dip into the crease of your thigh, fumbling as they reach for the waistband of the panties you’re wearing. Katsuki’s desperation is so palpable that he finds himself panting as he slips his fingers into the sides of your underwear, yanking them down. You gasp at the force of it and he swears he hears a small tear as he pulls them from your cunt, the crotch sticking to the lips of your pussy.

He leans his hips forward again, sliding his cock between your folds with a deep grunt. His mouth finds your neck and he bites along the side of it, lathing his tongue over your pulse point. It’s like he can taste you. Salt and that stupid perfume, collecting on his tongue as you dig your fingers into his back, his dick rutting restlessly against your clit. At one point, he almost slips in, his eagerness and your wetness making him careless. Katsuki sucks in a breath through his teeth, his whole body on fire.

The kitchen light shines down on his back and he can see the outline of part of his shadow on your thighs as he stares down at them, guiding the tip of himself to your entrance. He hears you wine when he presses against it and moves his hand down subconsciously to rub at your clit. An attempt to ease the stretch.

You tip your head back in a moan and Katsuki takes the opportunity to kiss your neck before settling his teeth against your shoulder and biting down harshly on the muscle connecting your neck and arm. You yelp at the sensation and Katsuki shutters at the sound, willing out a choked I’m sorry as he slides into your wetness. His hands push into the delightfully soft flesh of your upper thighs, the fat spilling up around each individual digit as he uses your legs for leverage, sliding you forward even further to better seat you on him.

Your legs are shaking and he can feel the way your nails dig into his exposed shoulder blades. Your bunch up skirt causes the fat of your tummy to fold over in a way that practically makes Katsuki drool. He urges himself to pause, attempting to come back to his senses as the quirk kicks into high gear. There’s relief in being inside of you, in feeling the flutter of your walls around his thick cock, but it also makes him desperate. Katsuki feels like he’s chasing something that he was desperately and it’s just out of his reach.

You’re breathing heavily above him, he can see the rise and fall of your chest from where his head hangs down, his hands trembling on the tops of your thighs. He looks up at you through his lashes, his vision foggy around the edges as if he were peering through a tube. You’re at the end of it, your eyes glassy and mouth open, returning the look. Your eyebrows are knitted up in pleasure, but you almost seem confused.

“What are you waiting for?” You breathe out, the first thing you’ve said since he started touching you.

The tone of your voice is needy, with a delightful whiny lilt that makes him groan out loud. He can barely manage the words that come out next, his brain half mush, and he feels the way his cock jumps inside of you.

“Don’t wanna hurt you,” he says through gritted teeth, his breath coming heavy.

There’s a pause and he feels the distinct sensation of you squeezing down around his cock, like the idea turns you on.

“Use me,” you respond cautiously, your voice still containing that needy lilt.

Katsuki’s hips fuck up into you voluntarily and he feels the way his breath catches in his throat at the near desperate sound of your voice.

“Say that again.”

“Use me, Katsuki,” you respond, choking on your words as he fucks his hips up into you.

You reach for his face, taking it in your hands and drawing it close until it’s just in front of yours. Then, your palms slide down his shoulders and he screws his eyes shut and fucks into you again, harder this time, causing your body to jolt upwards on the counter.

He curses under his breath, pushing one leg further to the side and fucking his hips up into you roughly. You’re looking right at him, your expression drawn and pleasure-soaked, sweat collecting on your forehead as your mouth drops open into an o-shape. You punctuate his thrusts with high pitched yelps, squeaking out your pleasure and the deepness of where he’s hitting through choked moans.

Katsuki’s hands move up your stomach to roughly cup your breasts, his mouth so close to yours that he’s practically breathing in the sounds you make in exchange for his own hurried groans. He kneads at the fat of your chest, rolling your breast under his fingers before taking your nipples and pulling lightly on them.

He’s aware of just how rough he’s being, just how hard his hips are slapping yours, but he feels like he can’t stop. Katsuki chases a high so fucking desperate that his body is on autopilot, reaching and touching and moaning unabashedly as the room fills with the wet sound of his balls on the backs of your thick thighs.

You push your chest forward towards him, legs spread wide to make room for the width of his hips between yours as he bullies that perfect sensitive spot inside of you. Katsuki feels the way he makes you flutter. Every shift of your body, every involuntary squeeze of your cunt as he drags his cock along your walls, registers as if he were a part of you. His skin tingles everywhere you touch and the drag of your nails over his shoulder blades makes him want to crawl into the deepest part of you. Even the sound of your voice, drawn and desperate and mildly overwhelmed, feels like a drug to him. Every sense he has seems to be acutely attuned to just how badly he needs to fuck your lights out.

His hands slink down to your hips, resituating you and pulling you flush against him. Then, he drags his cock all the way out of you and quickly ruts back in, moaning as he does. His pace picks up, manhandling you forward on the counter until he is supporting most of your weight. You gasp, your hands gripping his shoulders as you let him use you like a toy.

Katsuki chases his high, his stomach seeming to wind tighter and tighter but never finding that perfect snap and release. His movements grow faster, using all of his strength to fuck his hips up into you, barreling his cock against your gummy walls and bullying your sweet spot. He feels the way you tighten down around him, your body tensing and fingers digging crescent moons into the tops of his shoulders.

“Ka-” you choke out desperately, your voice breaking. “Wait, Katsuki, wait! I’m gonna-”

You shudder, your thighs squeezing around him as he continues to fuck you.

“Do it,” he seethes, “just fuckin’ do it.”

The end of his sentence comes out as more of a whimper as you cry out and squeeze down around him, squirming in his grasp as you begin to twitch with every additional thrust. Your body shakes, legs locking around him and struggling to hold him inside as he fucks you clear through your orgasm and then to the other side.

Katsuki’s voice breaks, almost whimpering like an animal as he buries himself in your pussy over and over again. He wants to smother you, he wants to completely cover your body and get as close as he possibly can. He’s already so much bigger than you, so much broader, how hard could it be to swallow you completely?

Katsuki’s hands come up under your ass as he wordlessly lifts you from the counter and moves to the couch on desperate, shaky steps. He lays you down, slipping out of you for a moment, before pressing a hand to the inside of your thigh, spreading your legs, and sinking his cock back into you as he crowds his body over yours.

“You know what?” He says, not really sure what’s going to come next. His head is so clouded with the quirk that he can’t think straight. “I’ve wanted to do this forever. I’ve wanted to fuck you for so- long-”

He screws his eyes shut, almost angry with the way he can’t seem to hit that high, teetering on a desperate and near painful edge.

“Those fuckin’ pencil skirts,” he says, unable to control his words or sharp tone. “The way you wear your hair, that damn look in your eye that constantly makes you seem like you’re beggin’ for it.”

Katsuki whines, a sharp sound from the back of his throat, as you tighten up around him. He meets your gaze, clouded and watery eyes accented by the delightful furrow in the center of your brow.

“And then you show up here,” he groans, not even sure of what he’s really saying. “Blouse unbuttoned, looking for trouble. I’m gonna fuck your lights out. ‘Till you can’t even think about fuckin’ anyone else.”

He leans in close, his mouth right up against yours.

“This is g’nna make you mine, right?”

You nod, your movements clumsy, and pull him close to you.

Katsuki loses all of his sense, burying himself in the feel of your pussy and the way he sinks into you, giving into the desperation of the quirk. He can feel just how deep he’s hitting, the way you suck in sharp, whiny breaths with every inward thrust. Katsuki’s hands grip your waist, pulling your ass up off the couch so that his angle is better.

His cock seems to drag endlessly against your overstimulated, pillowy, insides and you practically drool around. He feels like a dog slobbering over meat, any semblance of politeness completely gone from both his expression and his movements. This is going to fucking ruin your friendship, but he doesn’t even have half of a mind to think about it, so drawn into the delightful feel of your body and the aching in his cock that only seems to subside slightly with every thrust.

You try to choke out the word “again” and he feels like he knows what’s coming. Your whole body tenses, legs locking around him as you cream over his cock for the second time.

This seems to get Katsuki somewhere, the sensation of your pussy clamping down finally giving him some leeway to relief. He hits the edge of an orgasm, leading himself to the finish line.

The tension in his belly grows, cock twitching inside of your fucked out cunt. His fingers dig into your hips and he collapses forward, rolling his body so that the head of his cock catches perfectly inside of you, massaging and churning you up. You’re moaning, though maybe it’s more adjacent to whining, and Katsuki can hear himself mimicking the sounds, his body leading the way.

Then finally, on a pathetic and broken whimper, Katsuki cums. His whole body tenses, weight pressing down on you as he buries his face into your neck and lets his voice out beside the hollow of your throat. The relief and pleasure is so intense that Katsuki feels the way every muscle in his body tenses and lets go, filling you up with as much of him as he has to give.

His hips continue to pathetically rut into you, little choked moans escaping his lips as he uses his own cum as lube for his weak little thrusts. Then, he completely relaxes.

Katsuki feels the way his skin stops burning, the way the desperation at the back of his throat subsides, how his body rids itself of the quirk as quickly as the arousal came on. He shudders, coming back to himself and raising his head to peer at your expression.

You look exhausted, hair a mess and face covered in a thick sheen of sweat. You still flutter around his cock, your hands gripping his shoulders as you try and ride through the overstimulation of just having him inside of you. Katsuki furrows his brows, exhaustion creeping into his muscles. He raises his hand and uses it to push stray strands of hair from your face with his palm on your forehead. Then, with a clear mind, he leans forward and kisses you.

You blink at him for a second, before giving a weak smile, raising your eyebrows and letting your head fall to the side. Katsuki winces when he pulls out of you, sucking in a sharp breath and standing to his full height. He places a hand on his forehead like he’s assessing the situation, staring at your body, still fully clothed with your skirt pushed all the way up your stomach and your blouse missing a button at the top.

He wordlessly walks to the bathroom and wets a washcloth with warm water, walking back over to you and wiping down the exposed parts of your body. You don’t really say anything to him, but you smile quietly while he gingerly wipes you down, your smeared makeup accenting just how much of a mess he’s made.

“Fuck,” he says. “I’m sorry, this isn’t how-”

“How you wanted this to go?” You say softly, the corners of your lips turning up.

Katsuki feels the way he flushes, all the way to the tops of his chest.

“No, it’s not,” he admits, running a hand over his face as he crouches beside you.

You laugh a little and he furrows his brows at you, frustrated and embarrassed.

“You’ve got a bit of a possessive streak, huh?” You tease lightly.

“I got hit with some asshole’s fuckin’ quirk and-” he begins explaining himself, something he probably should have done when you showed up at the door.

“It was good though,” you say, tilting your head at him from where you lay.

Katsuki blinks at you, his expression completely flat. You should really know just how fucking crazy you drive him. Then, he scowls a little, not because he’s upset, but because he’s currently feeling the opposite and that makes him awkward.

“You’re into that shit?” He says, a bit incredulously.

You shrug and give him a coy smile.
