→ summary: Your birthday is around the corner. What better gift than your boyfriend, the #1 Hero Deku, finally giving you what you want the way you want it: rough and kinky. But first plot!

a/n: Sorry about the crap summary and title, I'm working on that lol. So this is my first fic for the bnha fandom and first attempt at writing very explicit sex scenes and venturing into kinks/BDSM, so please be kind, but also I’d love feedback! This was supposed to be a cute four-page oneshot but turned into a sixteen-page, 7k+ word behemoth, hence the self-indulgent tag ‘cause I couldn't stop writing. I hope you enjoy the fruits of my labor ;)

In a few days, you’ll be turning twenty-four. Your birthday has always been an odd day you think for someone with your quirk because age really was just a number. That’s not to say you weren’t planning to do something fun, at least if you could figure out what you’d like to do. Okay, so that was a lie. You knew exactly what or should you say who you wanted to do and that it involved getting your back blown out. As soon as the thought pops into your head, your epiglottis forgets its job, and you choke on the sip of UCC coffee, you had tried to swallow. You cough to clear your airway, gasping when air finally expands your lungs. You tap your pen nervously against your desk, eyes scanning the other pro heroes’ faces in your agency. It seems your sudden outburst hadn’t disrupted the comfortable silence of the natural lull of the workday. A beep from your hero pager pulls your attention away from people watching in the office. Coordinates flash in five consecutive seconds before the transmission ends. You stand grabbing your toolbelt and strapping it across your hips; you make your way to the front. As you near the exit, you hear your hero name being called. You turn and see Yaomomo briskly walking towards you.

“Hey Creati, you got the page too?”

“I did, sounds like they’ve made a bit of a mess of things.” You scoff good-naturedly.

“When do they ever not. Were they really like this during your time at U.A.?” She giggles and nods her head. You wonder if you’ll ever stop cleaning up after the nation’s top three heroes.

“Better get going then, we both know they share a singular brain cell, so there’s no telling how much time we have to fix things.”

“Atomic!” You laugh at Yaomomo’s weak attempt to scold you — the amusement in her black eyes softens the tone.

−−−−−−−−−−−−−−−−

“Oh my.”

You blow out a low whistle. Ice and scorch marks are scattered across the street and surrounding buildings. Explosive ash is still gently falling from the sky, and black tendrils are haphazardly keeping electric poles, exposed building foundation, and an abundance of wrecked vehicles from collapsing.

“Creati, check the building foundations. Create new beams and weld them together if necessary. I’ll get started on the pole, we can’t have a live electric wire falling.” She nods, and you split off. The work is slow and arduous, but the orderly nature of reorganizing and coaxing atomic particles back into place helps the time pass quickly. You’ve just finished rearranging the anatomical structure of a car hanging from a, thankfully, undamaged light pole, so that it falls to the ground weightlessly. You touch the damaged side, pull it back together, and return the car to its original density. You give the car a quick tap with the toe of your foot to test the structural integrity, satisfied you step back taking in your handiwork. What had a few hours ago looked like a DEFCON 3 military mission gone awry is now back to looking like an ordinary Japanese street. Well, as normal as you and Yaomomo could reconstruct — you weren’t miracle workers, and Ground Zero’s explosive residue was hard to get rid of. Instead, the way it collected and hung in the atmosphere made it difficult for your quirk to erase without condensing the air. That was out of the question unless you wanted to suffocate Yaomomo. Which you didn’t, so the employees of these buildings would be dealing with the smell for at least a week. Sighing, you tuck your hands in your pockets and make your way over to Creati. Her welding mask obscures her face, but you know it’s in deep concentration. After she cuts the torch and pushes the protective gear up, she gives you a smile.

“All done?”

“Just about.”

“I’ll page H.Q. Might even lodge a formal complaint against those three bird brains while I’m at it.”

“(Y/N), you can’t be serious.” She shoots you an incredulous look.

“They make this huge ass mess and don’t even bother to wait for us to arrive before dipping. Total dick move.”

“Ah-huh.” You don’t like the teasing note in her voice.

“What?”

“Oh, nothing.” You cross your arms defensively.

“Spit it out, Yaoyorozu.”

“You sure your foul attitude has nothing to do with not seeing Deku?” You roll your eyes.

“I’ll see him at home like I do every day. So no, I’m not upset about not seeing him.”

“If you say so.” She gives you a look, and you let out an exasperated puff of air.

“You cannot still be stuck on that!”

“Hmm? What do you mean?” She bats her eyes at you innocently while creating a duffle bag to transport the welding equipment.

“That God awful theory you and Ashido have about me having a hero kink for Izuku." You begin to walk side by side back to the agency. You hand her an energy bar from your utility belt.

“I mean, you do get very flushed whenever you see him on patrol. Like, if it were a hentai video, you’d definitely be drooling with your tongue lolling out of your mouth.”

“Ugh!” You shove her with your shoulder. “That is so gross.” Both of you laugh, and after a small lapse into silence, you give.

“Okay fine. I might get instahorny whenever I see Izuku in costume, but I can’t help it. He just looks so good, and it’s heightened because I know what he looks like out of costume, and then all I want to do is jump his bones, but of course, I don’t because propriety. So I’m left with all this pent up sexual frustration!”

“So, are you going to ever mention this to him? Your birthday is in a few days and if I may be so bold —”

“It’s never stopped you.” You mumble under your breath with a smile.

“I’d suggest you request it be your birthday present.”

“Pfft. Yaomomo, we’ve been together almost a year and a half, and while our sex life is fucking phenomenal, I’m talking multiple orgasms almost every time, amazing — it’s been very strictly vanilla. Not from any lack of trying on my end, but every time I’ve tried to spice things up, he gets as close as humanly possible to spontaneous combustion. Don’t even get me started on the one time I tried to get him to choke me while I —”

“(Y/N)! Stop, goodness, I do not need the play by play of your and Izuku’s sex life. I just,” she massages her temples, “wanted to make a suggestion. While I’m relieved you feel so secure in our friendship to be so open, please remember I went to high school with him. He’s like a little brother.”

“Oh, Yaomomo, there’s nothing little about him.” Her face pales, and you can’t stifle your cackle. It quickly becomes a full-blown laugh that rattles through your body.

“I went a little too far with that last comment, gomen. On a serious note, though, how would I even go about asking him? ‘Hey babe, it’s my birthday so I want you to fuck me until my knees are jello while in your hero costume because it gets me all hot and bothered oh and since I’m risking it all I’d love it if you tied me up and maybe choked me too.’”

You glance over your shoulder, a look of profound regret is plastered over Yaomomo’s face. You give her an impish grin.

“Doesn’t quite roll off the tongue does it.”

“Oh (Y/N).” Your friend shakes her head. When you finally turn the corner onto the street, your hero agency is housed, you catch sight of a mop of green hair. You pick up your pace, a mischievous grin on your face. Using your quirk, you redistribute your mass, so your footfall’s noise against the pavement is silenced. Izuku is talking with someone, his back turned to you. The goods were on display. When he’s in reach, you stretch out your arms, hands cupping his butt you feel him stiffen as you whisper against his ear.

“You’re under arrest for transporting illegal buns of steel.” You watch the blush creep up from his neck before capturing his entire face. He turns his neck, trying to get a good look at you.

“Wh-what!” You begrudgingly let go of his ass, and he turns his body to face you, his freckles standing out against the pink hue of his flustered expression.

“Sorry hun, I don’t make the rules.” You shrug your shoulders.

“I- I, (Y/N) that’s not even a legal penal code! A-and there’s no way I could transport enough steel on my person to warrant a body search.”

“Ooh Deku,” you loosen up the state of your atoms, allowing them to vibrate in mock arousal, “I love it when you talk legal code at me. Repeat it: penal.”

He flounders for a reply, mouth agape at a total loss for words. You giggle at his expression, a total deer in headlights. The person he’d been talking to finally makes themselves known.

“Atomic, you’re still teasing the living soul out of Deku per usual. Glad to know things haven’t changed ‘round here.” His shark tooth smile pulls an equally toothy smile from you.

“Eijiro! When did you get back? I’ve missed you.” You rush to the redhead, and he reciprocates your hug, holding you tight.

“Man, I’ve missed you too (Y/N). The States were cool, but there’s no manlier place than home sweet home.” You pull back and take him in. He looks the exact same if not a little bit more tanned.

“Damn straight.” Yaoyorozu arrives at the end of your reunion. Her excitement at seeing her old friend is nearly palatable. They catch up enthusiastically, and you saddle up next to your boyfriend, who’s finally gotten his blush under control.

“Hey, babe.” You give his cheek a chaste kiss, and he smiles.

“Hey, love,” Izuku gives your hand a squeeze, “How was your day?”

“It was pretty run of the mill except for the utter shitstorm Yaomomo and I had to clean up in Minato City.” You glance down and watch his feet shuffle from side to side.

“Huh, sounds pretty epic.”

“Not the first, second, or even the third word I’d use, but we’re all entitled to our opinions. And don’t you try acting coy with me, Izuku! That blonde ticking time grenade, the confused weather pattern, and your quirk were all over that place.” Izuku gulps.

“I expended a lot of energy cleaning up after you and your friends baka. As compensation, you’ve gotta cook me curry rice. Deal?”

He kisses your cheek in assent.

“Great!” You beam. “I’m gonna go change, be back in fifteen.” You disappear through the agency’s massive double doors. Yaomomo watches until you’re out of view before she walks over to Midoriya.

“So about (Y/N) ’s birthday . . .”

−−−−−−−−−−−−−−−−

When you come out, you find a peculiar scene waiting for you. Yaoyorozu has crafted a fan for, you presume, Izuku, who is so red you could almost see the light refraction from his face’s heat and sweating by what looks like the gallon. Eijiro is by his side, trying to calm him down. You heighten the sensitivity of your cochlea to pick up the tail end of their conversation.

“It’ll be super manly, dude!”

“Bu-but I’ve never . . .” Your boyfriend seems tongue-tied.

“You’ve definitely got it in you,” Eijiro slaps Izuku on the back, “Plus Ultra!”

Izuku echoes Eijiro, but you can tell his heart isn’t in it.

You return to your average level of hearing and walk up to the trio.

“Everything good?” They all look at you with expressions that clearly scream, ‘No, everything is not good dumbass.’

“Riiight, foolish question. Izuku, babe, do you need me to help you?” He squeaks, and that stops you dead in your tracks. The last time he had squeaked in your presence was when he’d asked you out on your first date, and you think it was mostly because you had bluntly told him you had every intention of having sex with him if not after your first then for sure after your second date. He didn’t even squawk when you made good on your declaration, and you had been positive he was going to. Your assurance cost you a ¥2,000 bet with Ochako and Shoto. Whatever had transpired while you were changing had him spooked.

You crouch down and gently take his face between your hands. His cheeks are unnaturally warm. Closing your eyes, you reach out with your quirk to scan his vitals. What the actual fuck? Izuku’s pregenual anterior cingulate cortex is enormous. Your boyfriend is next level embarrassed. His heart rate is in the 200bpm range, which should have been impossible because it only ever got that high when he was exercising, and you were quite familiar with getting it there.

You’re honestly shocked his heart hasn’t started to palpitate with the sky-high levels of cortisol in his blood and high heart rate. Taking a deep breath, you begin to gently persuade the firing neurons near his PACC to chill, its size slowly decreases. You travel down to his hypothalamus and rearrange some of its chemical balance, so it stops producing corticotropin-releasing hormone, creating a negative feedback loop that would lead to his body to drop its cortisol production. You vasoconstrict a handful of the blood vessels in his face for good measure, hoping to cool it down. Your eyes flutter open, and the ruddiness is gone, and his cheeks feel cool against your palms. He gives you a weak smile and gosh that smile, these freckles, those lively emerald eyes. You lean your forehead against his, taking a moment to collect yourself. You kiss the tip of his nose before pulling yourself up, stretching once you’re fully upright.

“Well damn, I’m starving now. I know I said you had to cook for me, but I don’t think I’ll last. What do you say, Number 1. Hero, care to take me out to eat?”

Izuku gets to his feet, with a bit of help from Eijiro, who keeps a hand wrapped around his waist to keep him from stumbling.

“Yeah, of course, love. Just tell me where you want to eat.”

You grin in delight. Before making a decision, you turn to your two other companions. You’re not sure when Yaomomo had time to change, but she’s no longer in her hero costume.

“Would y’all like to join us? Izuku’s treat.” Your cinnamon roll’s protest is drowned out by their loud acceptance.

“I mean, if my bro is gonna treat us, then how could I say no?”

“How gracious Izuku, I’d love to share a meal with everyone.”

“Let’s get going then!” You grab Izuku’s hand and turn around, heading in the direction of the train stop. The walk will give you time to decide where you want to eat.

−−−−−−−−−−−−−−−−

“Hold on one sec, almost got it.” You pace next to Izuku; the pressure on your bladder almost debilitating. At the click of your front door unlocking and seeing Izuku push it open, you rush through over the threshold. You kick the heels off your feet, your slippers abandoned at the entryway as you make a break for the bathroom. You can’t get your underwear off quick enough. The relief is almost pleasurable. You’d forgotten what it felt like to pee while exceedingly inebriated. Typically when you go out drinking, you elevate your liver’s production of alcohol dehydrogenase so you can avoid getting drunk, but tonight was your birthday celebration, and you wanted to get shitfaced, so you dialed it back. Now that you’re home and not interested in a hangover, you make the necessary adjustments to your liver. The night out had been a pleasant surprise. More people had shown up than you’d been led to believe would, most importantly, your younger siblings had stopped by — you hadn’t seen them since moving to Musutafu to pursue your hero career. You finish reminiscing over the night’s events. Quickly wiping, you flush the toilet and wash your hands. When you open the door, you find your slippers are there waiting. He was a total sweetheart.

You slide your sore feet in and sigh at the fluffiness. You make your way to your bedroom, surprised to find it empty. Where had Izuku gone? You take off your earrings, dropping them into your jewelry box. Making your way to the main bathroom connected to your room, you’ve just finished wiping away your makeup when you hear the door open. You walk to the bathroom door to peek and gasp as soon as you spot the figure closing the door behind them. Now you’d be the first to admit you are a horny bitch, but never have you felt your pussy throb with such a deep longing the way it was throbbing now. You stand still dumbfounded at seeing Izuku in his hero costume in your bedroom.

“Babe?” You try to suppress the quiver in your voice.

“Ma’am,” He tilts his head in greeting, “I got reports of a villain in the vicinity. I’m Deku, and I’m here to take care of you.”

Why the fuck did he just introduce himself? And a villain? You reach out with your quirk but don’t feel an unknown presence nearby. You start to walk towards him but stop at the foot of your bed. He meets you there, and you don’t know what to expect, but it definitely was not him pushing you onto your back. You fall with a muffled thud against the comforter. You stare up at him at a complete loss. You then become hyper-aware of what you’re wearing. The sparkling strappy mini dress leaves little to the imagination, and you’re positive that from his angle, Izuku can see your panties and the growing evidence of your arousal.

“Apologies, ma’am, but I’ll be using my quirk to restrain you as a precautionary measure.” Your mouth goes dry as you watch Blackwhip manifest wrapping around your wrists, pulling your arms above your head, and adhering to your shared bed’s headboard. You have to scoot yourself back a few inches to ease the tension in your shoulders. Holy shit. He just tied you up. This whole time he’s been standing at the end of the bed taking you in. You know your face is flushed, and you can feel your nipples brushing against the material of your dress now that you’re so turned on. Izuku’s hands come into view, and that somehow gets your mouth to work again.

“What are you going to do?” You arch an eyebrow and part your lips to let your tongue dart out and wet them. Fuck Yaomomo wasn’t off the mark with her comment.

“I’ll need to do a full-body search to ensure you’re not concealing anything illegal on your person.” You don’t have time to respond before his gloved hands caress down your pinned arms, across where your neck and shoulders meet. Leaving goosebumps in their wake. He cups your breasts, his thumbs brushing over your hardened nipples. You groan as the sensation travels down, pooling between your legs. He moves down your sides, slowly over your exposed thighs sticking strictly to the outside of your legs until he reaches mid-calf. You feel his hands move, and suddenly their inching closer to your aching cunt. Using his right hand Izuku runs a finger teasingly up between your clothed slit and your hips give an involuntary buck. He removes his finger and tuts at you, that pisses you off.

“What the fuck Izu —” You stop yourself when you see another tendril of black materialize near your face.

“Don’t make me gag you. My name is Deku, and you will address me as Deku-sama.” There’s a finality in his tone that leaves no room for argument. You’re torn between being really fucking aroused and very vexed at this role reversal. You’d always been on top, literally and figuratively, and now here he was, your cinnamon roll, threatening to gag you and not even blushing about it. He takes your silence as understanding and begins to hike up the bottom of your dress. With your midriff exposed, he finally settles between your legs, his toned abdomen flush against you. He places an open-mouthed kiss just above your belly button, his tongue flicks out to taste your skin. Izuku’s lips continue to roam over every inch of your exposed abdomen, sucking and biting. He’s going to leave love marks all over your stomach, you’re sure. His hands travel up under your dress, coming to rest just below your breasts. You feel the flat of his tongue working its way towards his hands. When you can feel his breath tickling you already hard nipples, he pulls his face away. You squirm and pull against your restraint — you feel them tighten.

“What is it you want, villain?” Fuuuck. The word falls from his lips wrapped in sinful promise sending another steady pulse of need through your body. Your nervous system was on fire.

“I want you to touch me.” You try to taper down the pleading in your voice, but the mildly amused expression on Izuku’s face says you failed.

“Like this?” His hand runs down your neck, over your dress and through the valley of your cleavage, past your naval stopping at the band of your panties. It dawns on you that he was teasing you.

“Or like this?” You’re not sure when his gloves came off or how he managed it, but one second you’re covered by the flimsy dress material next, the straps keeping it up are torn, and the dress pulled down. You hiss at the shock of the sudden temperature change, but quickly warm up as calloused fingers massage your breasts. A greedy moan is the only answer you can manage as you arch your back into his touch. He leans closer, breath warm against your neck, and moves a hand down to grip your ass,

“Let’s see if these are illegal buns of steel.” Even with how incredibly husky his voice is, you almost laugh at his remark’s absolute absurdity. Still, having maybe foreseen your reaction Izuku wraps one of your nipples between his lips before you can utter a sound.

“Deku-sama.” You inhale sharply coming completely unwound as his tongue flicks and swirls. His mouth sucks and pulls playfully. When his teeth graze your nipple, you contemplate making your hands boneless to escape the restraints just so you could tangle your hands in his hair; even with the undercut, you knew you could make him moan. The idea is quickly dashed as Izuku releases your now overly sensitive bud with a resounding pop that sends the ache in your pussy into a frenzy. Good god , he hasn’t even gotten inside of you yet. He treats your other nipple with much the same attention. However, this time, he lets his teeth give it a gentle nibble, and the shock of the feeling causes your skin to prickle. You feel him grin at your reaction before giving your nipple a farewell lick. He captures your lips, shoving his hips down against your own, as his hands’ ghost over your neck. You hook a leg around his hip, pulling him closer, trying to create as much friction as possible as you roll your hips upward. He lets out a breathy chuckle, as his mouth moves to replace his hands. He kisses up your neck, his breath tickles your ear, and you stutter out a needy whimper.

“Someone’s eager.” You groan in frustration as he pulls back. His hands grab hold of what’s left of your dress, and you help him get you out of it. He runs a finger up your stomach, stopping just below your sternum. The tip of his index finger traces a lazy circle before leaving a trail of goosebumps back down to your hip. The pressure of his finger is replaced by his mouth, biting the flesh of your hip crease hungrily. He kisses his away across to your opposite hip, traces of his kisses wet against your skin. You feel his fingers toying with the lacy hem of your panties before he hooks them in the elastic, pulling them down. You lift your hips as they pass over the curve of your ass, and you wriggle in anticipation. Izuku braces his left forearm against your right thigh, pushing your legs wider. His index finger explores your wet folds, dipping briefly into your slit, before brushing against your swollen clitoris.

“Deku-sama, please .” You don’t care how desperate you sound, the ache in your pussy is becoming unbearable. The slow burn was killing you.

“Since you said, please.” He slips a thick finger inside of you, curling it just so it massages the soft and spongy spot that makes your toes curl and lewd obscenities fall from your parted lips.

“Aah, fuck. Fuck, yes, there, right there. More. Izuku give me more.” A second finger is roughly inserted. You cry out as a jolt of ecstasy consumes every inch of you. He begins to scissor his fingers back and forth, “It’s De-ku sa-ma,” each thrust emphasizing the syllables of his declaration. You rock your hips up, trying to get his fingers deeper because you are close. You can feel the dam getting ready to burst. When his thumb circles your clit, you feel yourself clench around his fingers. He inhales sharply. You bite back a moan as stars begin to dance across your vision. The rhythm of his fingers picks up, and the pressure on your clit begins to be too much.

“You’re about to cum.” It’s not a question, but you manage to pant a yes, and it becomes your undoing. Tongue replaces fingers before you can bemoan feeling empty, hands wrap under your thighs, keeping you exposed when they instinctively try to shut. His fingers dig into soft flesh, and the pain leaves you dizzy for more. He unhooks his left arm from your thigh, again using his forearm to keep your leg down. Two fingers spread you open, and his breath is warm, and you screw your eyes shut because fucking hell, you feel ready to erupt. You feel the warmth of his tongue as it slips inside you and starts to lick around. His nose brushes against your clit as he laps up your wetness. When he takes your clitoris in his mouth, you feel yourself at the edge of a precipice.

“Y-your fin-fingers. Deku-sama.” You frantically tug against your binds as you arch your hips rutting into his face. Fuck. Fuck. Fuck. You feel yourself drowning in pleasure when his fingers join back in the fray. You’re full, and his tongue is everywhere. Inside you along with his fingers, pressing in all the right places. There’s no room to be embarrassed by your body’s wet sounds as you thrust against his fingers or the sounds he’s eliciting from you — loud, throaty, and gluttonous. He laps up the juices wherever they end up, on your thighs, in your folds, the space between your pussy and ass. At your clit he teases with nibbles, quick flicks of his tongue, and long flat strokes. He was treating you like you were his favorite meal. Coming back for seconds, thirds, fourths. You lose track of time. The air crackles with electricity, Izuku, the electromagnet to your copper coils. It sparks against your skin. Were you doing that? You couldn’t tell, but it didn’t matter because something was building. You feel it in your core, your quirk causing your atoms to buzz in excitement. He lets you hook your legs around his back, locking your ankles. You make a strangled noise when a particularly aggressive thrust combined with the head-splitting euphoria of Izuku’s tongue on your clit brings your Earth stuttering on its axis.

“Oh fuck, oh kami. Shit, Deku-sama!”

You flicker in and out. One second howling Izuku’s name like a prayer to the Gods, hips rolling up to meet his mouth. The next, you find yourself weightless in a void no longer in a corporeal form. What the fuck? It lasts no longer than a second before you return to your body and the sound of him cooing against your aching cunt.

“That’s it, cum villain. Cum for me.” And cum, you do. Waves of fiery ecstasy set your body aflame. You clench your fists and use your legs to pull Izuku’s face further flush against you. When you think you can catch your breath, Izuku surprises you by coaxing you into another smaller orgasm. You don’t know how he did it, but you really can’t complain, you’re feeling blissful as fuck. The bed creaks as he shifts back onto his knees, unwrapping your legs from around him. Blachwip is deactivated, and your arms fall uselessly to your sides. You feel your legs quiver from exertion, and you watch your chest rise in fall sporadically as your breathing levels off. You prop yourself up on your elbow to give Izuku a once over. He’s got a bit of sweat on his forehead, you can see the outline of his erection against the front of his hero costume, and your cum glistens on his nose, mouth, and chin. Not sure how you manage it, with your body feeling so close to putty, but you scoot back, pulling yourself up into a seated position, and rock forward onto your knees so you’re facing him.

You move closer, so your knees brush against his. Now that you’re close enough, you can see how blown his pupils are. They almost wholly eclipse the dark shamrock of his irises. He had it bad for you. You could fix that. You grab his chin between your thumb and forefinger, tilting it down to your lips so you can lick it clean. When your tongue traces the outline of his mouth, a low moan rumbles in the back of his throat. You get his mouth open with a hard nip to his bottom lip. Tasting yourself in his mouth and on his tongue makes you squeeze your thighs together briefly before you let your free hand wander between your legs to stroke your clit and moistening labia. You give the tip of his nose a cutesy peck that almost brings a blush to his freckled face, but he remains in character, so you palm his cock with your damp hand grinning devilishly when he stutters an exhale.

“I want you, hero.”

Izuku’s chuckle is rich, and you can feel it reverberate against where your chests connect. You start to toy with the hair at the nape of his neck, the short buzz of his undercut tickles your fingertips. Sliding your hand up, you finally get to tangle your fist in his hair, your grip tightens, and you pull his head back, exposing his neck. Your tongue darts out to lick a stripe up to just below his earlobe, all the while your hand strokes him into fully hardening.

“I’m not fucking around, Deku.” Your voice is thick and your tone dark, dangerous. He grabs the wrist of the hand that’s between his legs and growls,

“Neither am I villain slut.” You swallow hard at his inflection on the word slut. You’d never been called a slut during sex, and under any other circumstance, you’re sure it wouldn’t have sent a thrill of arousal pulsing from your fingertips down to your toes. He brings the hand up above your head, reaching behind his head to grab your second hand. You give him a feral grin, and his eyes flash before he sends you to your back. You’re about to stretch out your legs when he commands you to flip over onto your hands and knees. You do as you’re told, biting your lip as warmth begins to once again pool between your legs. You wish you could help him out of his costume, but it sounds like your help wasn’t needed. His dick grazes against the back of your thighs. A finger follows the curve of your spine. You arch into the touch and moan when it dips at your hip to tap your clitoris.

“You’re so wet already. You villains really know nothing about bedroom decorum.” He skims a hand over your stomach, stopping to grope and tease your hardened nipples.

“Oh? Keeping a woman in suspense isn’t exactly proper in my book De-ku sa-ma.” You look over your shoulder with a smirk.

“You’re,” he thrust into you without warning, quickly turning the grin on your face into an open-mouthed ‘oh,’ “not,” he pulls out, so the tip of his head just barely touches your cunt, “a woman.” He pushes into you, swearing under his breath as you push your hips back to meet his momentum. A ragged breath escapes your lips as you adjust to him, filling you. Shit, the boy is thick. His nails dig into your hip as he continues to fuck you at a painfully slow pace. Fingers tweak your nipples, and you feel your whole body flush with pleasure. You clutch the bedsheets in two tight fists when he starts to quicken his thrusts. His chest is slick with sweat against your back, his tongue tracing circles into your shoulder. An aggressive stroke sends the head of his cock rubbing up against your G-spot, and you feel your walls squeeze around him.

“Shit, shit, fuck Deku. That’s it. Just keep putting pressure on that spot.” You feel your elbows buckle, and you expect to crash into the bed. Instead, black tendrils wrap around your arms to keep you upright. This is definitely not how Lariat intended Blackwhip’s tendrils to be used. The thought makes you giggle. It seems that this was not a sound Izuku wanted to hear coming from you. He bites down on the spot of your shoulder he’d been suckling, making his displeasure known. You feel him adjust himself behind you, perhaps too quickly, because he slips out of you, and you protest immediately with a loud whine.

“I’ll give you something to whine about.” He thrust back into you, your knees go weak, and your pussy’s stimulation begins to pull the taught rope of your impending orgasm closer to snapping. One of his hands grabs the hair at the base of your neck, tugging with just enough force to tease a guttural mewl from you.

“That’s more like it.” You’re so overstimulated, with the rhythm of his dick coming in and out of you. The attention he’s paying to your clit, you scarcely have the headspace to be shocked by the personality change. Izuku doesn’t release his hold on your hair; instead, he deactivates Blackwhip and uses the grip to guide you, so your back is flush against his chest. You can smell the muskiness of his sweat with him so close. It mingles in the air with the scent of your arousal. Sex, the whole room smelled heavily of your fucking. He brushes a thumb over your bottom lip, pulling it down gently. You open your mouth, taking it in, holding it gently between your teeth, your lips acting as a cushion. You suck on Izuku’s thumb, letting your tongue swirl over the tip treating it how you would if you were instead sucking on the head of his cock. You hollow out your cheek and release his thumb with a satisfying pop. Your reward is the sound of Izuku’s heated gasp. The sound tightens the coil in your groin. You feel his right hand lightly trailing up your side. You expect him to stop to cup your breast, but a tingle runs up your spine when he skips it entirely. His thumb rests a few inches under your right ear, the fleshy part of his palm rests against your trachea, the remaining four fingers occupy the same spot under the opposite ear. You can’t hide your excitement as he begins to apply light pressure to your neck. It’s amplified when he whispers in your ear,

“Whose slut are you, villain?”

“I’m yours. All yours.” He squeezes a little tighter, and you squirm, gripping his left hip for stability.

“Yours, Deku-sama. I’m all yours.” You choke over the words while he loosens his grip satisfied with your correction. The brief bout of intoxicating lightheadedness dissipates quickly, but he keeps his hand around your neck.

You feel him, hard and slick, throbbing inside you, and you know he’s close. You prepare to ride out the coming crescendo that you’ll set off with your silver tongue.

“You’re getting close, aren’t you, hero? I can feel your cock pulsing.” He squeezes your neck tighter than he has before reminding you who was in charge. You dig your nails into his hip and bite your lip. Was he turning into a masochist, or were you?

“I want you to cum in me. Make me your bona fide villain bitch — think you’re up for it, big boy?” You were being so bold, goading him. It does the trick. He releases his hold on your neck, you’re a little sad, but are swiftly distracted by a sudden burst of heat and green energy crackling, the telltale sign of Full Cowl being activated. What the hell was he up to? Your answer comes moments later when his hands push your bent legs further apart, hooking his arms under your thighs to lift them up. You feel weightless, free, and so very wanton. Then like being dosed with ice-cold water, you come back to your senses; you’ve always been terrified of being picked up during sex. Your arms flail, searching for anything to grab hold of. They settle awkwardly at Izuku’s neck. Your breathing is a little erratic.

“You’re not scared of heights, are you?” Oh, he was being a total ass.

“Absolutely not.” You bite back.

“Heh.”

Sensing your discomfort, he places you back down on your knees, his hand returning to your neck — where it belonged. Shit, it was you, you’re the masochist. You feel him throb inside you, the head of his penis gets a little bigger and his cock harder. His movements become more sporadic. You take his free hand and lead it to your clit, you’d be damned if he cums before you. His groans become music to your ears, loud and ravenous as you roll your hips to meet his thrusts. Soon that’s all you can feel, like tunnel vision nothing else matters, there are no other options, but his cock burying itself deeper and deeper inside you as his fingers dance around your clit. He flicks and pulls, rubs circles, and you savor every second of it. Everything cumulates into a blinding flash of white-hot light as if you’re staring directly at burning magnesium. You hear him crying out your name, and it mixes with your carnal pleas into a cacophonous soundtrack to your mutual climax. He finishes inside you, the thick viscous liquid of his orgasm, filling you with more warmth than you anticipated. As you ride out your orgasm, you don’t stop gyrating your hips until you feel Izuku become soft. You let out a shaky breath as you come to a stop to catch your breath. You’re thankful that he doesn’t seem eager to pull out quite yet while you bask in the quiet exhilaration of having orgasmed three times this night.

“I’m going to pull out now, okay?”

You nod your head slightly, words out of reach with your euphoria’s hum still clouding your mind. Cum trickles down between your thighs, the sensation almost ticklish, but far more erotic. With nothing connecting you to Izuku, your body gives in to its exhaustion, falling forward unceremoniously. He wraps an arm around your waist, setting you gently down on your stomach. Rolling onto your back, you shimmy up onto a pillow to support your head. You glance up at Izuku and sigh in content. Hair stuck to his head, abs contracting as he slows his breathing (his heart rate close to 180bpm), and his left-hand traces the scars on his right arm absently. Even in such a worn-out state, he looked otherworldly. You lock eyes, and you pat his side of the bed next to you.

“Cuddle with me.” At hearing those three words, he sheds his façade, his eyes soften, his jaw loosens, and he eagerly obliges your request. He rests his head on your chest, your fingers playing with his hair as he gently brushes your side. You stay like this for a few minutes until he starts out of your arms like someone’s lit a fire under his ass. He sits up, you follow suit intrigued by what’s got him so worked up. You watch him reach across towards his nightstand. He pulls out a notebook and a pencil. You have to suppress your snort as he begins scribbling furiously. You couldn’t even pretend to be surprised, catching bits and pieces of his muttering.

“. . . dominated . . . choking . . . loud . . . buns of steel. . .” You can’t stifle the laugh that escapes you. He glances up and gives you a sheepish grin, his face like he’s been caught doing something he shouldn’t.

“You fucked me into another dimension, jot that down in your sex notebook.” A blush erupts across his face.

“I-I what? Seriously?”

“Mhmm, as seriously as my orgasm.” Embarrassment flickers momentarily in his eyes, quickly replaced by intense curiosity. You dare say you see a little triumphant gleam too.

“What happened, tell me everything, love.” You recount what he’d been doing with his tongue and fingers. The feeling leading up to it and what it looked like in this other dimension.

“Sounds like you’ve unlocked another facet of your quirk.”

“Looks like it, but it’s not really useful.” He gives you an inquiring look; you roll your eyes. He could be so dense sometimes.

“I can’t exactly have you eating me out in public every time I want to astral project now, can I?” His blush returns full force.

��Maybe there’s another way.”

“Possibly, but I’m beat. My legs feel like jello, and I’m starting to feel sore.” You massage your neck, glancing at your exposed breasts and the marks that speckle them. Izuku looks at you with worry.

“You can’t fix it with your quirk?”

“I can, but where’s the fun in that? One of my favorite parts of sex is feeling it the next day. I’m definitely going to tomorrow and maybe the day after thanks to you.” You give him a wink and admire as he fumbles with his words.

“Oh! Well, I mean. Yeah. No problem. I think?” He was definitely back to being your cinnamon roll. You giggle quietly.

“Before I go clean up, I’ve gotta know. How did you do that.” You motion with your hand, hoping he picks up what you’re putting down. He does.

“Simple, lots of research.” You squint at him, touching the pulse at his neck. It was slightly elevated.

“Ah-huh, and what else?”

“No-nothing!” The pulse quickens a little more.

“Did you role play with someone?” The idea sounds absolutely preposterous, but when he pushes your hand away from his neck and gets up off the bed, you know you’ve struck a nerve.

“You’re using your quirk, that’s not fair.”

“All’s fair in love and war. So, who was it with? Shoto? Eiji? Or was it Katsuki ?” The light hue of pink that creeps up his neck is all the confirmation you need.

“Ah,” you bob your head sagely, “it makes sense, babe, he gives off a total masochist vibe. I’d have practiced with him too. What was it like? Would he be open to a threesome? Or would it be a foursome since he’s got that not, so secret thing going with Eiji? Could I even handle the three of you?” You wonder out loud.

“(Y/N)!” Izuku rushes into the bathroom, adamantly trying to end this conversation. You weren’t letting this go, oh no siree, so you get out of bed and walk to the bathroom where Izuku’s turned on the shower and is standing under its current.

“Nice try. You’re giving me the details.” He sighs defeatedly.

“Can it wait until we’re in the bath.” You cross your arms in a huff, pouting.

“I guess.” Izuku grabs you, pulling you into the shower with him. You wrap your arms around his waist, resting your cheek against his chest. He gives the top of your head a kiss.

“Happy birthday, (Y/N).”

Happy fucking birthday to me. You smile to yourself.
