“Hey.”

“Hm?”

The sound of your typing is especially loud in the empty office. It’s a Saturday and neither of you are supposed to be clocked in, but when duty calls - it’s up to the two of you to answer.

“...I’m going to tell you something. If you so much as fucking laugh I will kill you.”

You don’t look up from your screen.

“Well that’s one way to start a sentence. I’ll try not to laugh.”

Katsuki slams his hand on the desk.

“I’m being serious,” He says in a half-yell. You look up from the edge of your laptop unflinchingly with a displeased frown, shaking your head and throwing your hand up half-heartedly.

“Fine, fine - I promise I won’t laugh. Can you stop being all ominous? You sound like Tokoyami.”

“There’s something wrong with me,”

“Well yes,”

“Not like that,” He hisses, taking a deep breath. He leans forward with his elbows on the table, hands clasped seriously as he covers his face. “...I think my fucking..thing..is broken.”

There’s a loud noise like a muffled laugh but when Katsuki looks up your expression is completely blank. Your lips are pressed tight, eyes out of focus as you continue to type. Or pretend to. True to your word, you don’t laugh but Katsuki still wants to fucking kill you.

“Oh? What uhm,” You clear your throat, lips trembling as you try to keep yourself together. “What brought you to that conclusion?”

He nearly snaps his pen in half.

“What do you fucking think?!”

“Hey. Calm down. I’m doing my best not to laugh but you are not helping.”

This is the sort of thing Katsuki would normally take to his grave. Not only is it genuinely humiliating, it is the sort of painful personal detail he wouldn’t share with anyone even if he was fucking them. It wouldn’t matter either, that his dick isn’t working - if the other ways he relieved stress were.

He’s got an average sex drive, sometimes lower but a high libido. Getting off is a physical response to a bodily need. Like eating food or taking a nap. It’s just because it’s a physical need, it is noticeable when the need doesn’t get met. He is painfully aware of it. It’s been weeks and he thinks he’s starting to lose his mind. Worse? He’s exhausted every human option trying to fix the problem himself, save for going to the dick doctor. His testosterone levels are fine, he gets check-ups more regularly than the average person. Given his reputation is at stake, he’d rather not get prescribed anything. He’s bought ginseng and shitty vitamins and medicine he had to ship from overseas. Anything and everything.

Picking up viagra at the ripe age of twenty four would give him psychic damage he won’t recover from, this much Katsuki is sure of. So not that. But everything else, every natural remedy conceived - he’s tried.

“I don’t know what to do anymore,” He says, pinching the bridge of his nose and willfully ignoring the sound of your strained huffing “I can’t fucking get….it up and I don’t know why. I’ve tried everything. Everything. I’m going crazy,”

“You know, it really says something about our relationship that you can confide to me about these kinds of problems. Like I’m so proud of us,”

“Shut up. I’m already miserable enough without wanting to fucking tell you - but the only other option is Shitty Hair and Izuku. I refuse to buy a single goddamn pill for it, and I know if I go to a doctor they’re gonna recommend it and—” He can’t finish the thought. It’s a little too sincere for the kind of conversation you’re having.

You’re a tactless person, so of course - you don’t bother with going along with the mood. Instead you smile like the evil bastard you are.

“And…?”

“You little—” He sighs rubbing his palms over his hands “And because I can trust you to be the least horrible option.”

“So you acknowledge my valiant efforts as your underling and assistant and know you’d be nowhere without me?”

“Shut up.”

“Aw, you’re sweet,” You say, promptly ignoring him “But yeah, I mean - no judgement. I would ask if you’ve had anything major happen but I unfortunately already know that’s not really the case.”

Yes. You, of all people, would know that no major changes have happened in Katsuki’s external life that would make it hard for his dick to function. You spend so much time together. Minus the time he spends working and catching villains in the world - you’re practically glued to his side. You’re in charge of all of his affairs, his schedule, all other personal things. Katsuki is naturally neurotic, but you handle all of it with grace and care. You know everything about him, which is why he is asking you about this problem.

(Does it border on unprofessional? Of course it does. But your relationship to each other degraded that border a long time ago. You’ve already slept in his bed and met all of his friends. And kissed him, but that’s irrelevant for now)

“I need solutions,” Katsuki offers, totally and utterly defeated by the situation at hand. “I’ve done everything. Taken every goddamn herb, done every meditation. Nothing is working. Nothing. I’m going to go fucking crazy.”

“Do you think just sleeping with someone would help? I know you don’t want to ask any of your friends, but maybe an escort? We can do it discreetly.”

“Fuck no. If it were that easy I would’ve done it.”

You pause. Katsuki can see the focus on your face and doesn’t know if it makes him feel better or worse. After an elongated period of silence, you perk up a little. You lock eyes with him and Katsuki briefly regrets bringing the whole conversation up in the first place.

“Hate to ask,” You say, though there’s not enough embarrassment on your face to make anything of that statement. “But uh, have you tried getting off with other things. Like something that isn’t your dick.”

He feels a flush creeping up his skin. “What the fuck are you talking about!”

“This is an important question,” You emphasize, an expression so alarmingly calm Katsuki doesn’t know if it makes him feel better or worse. “Cause if the answer is no, then that’s basically the best solution.”

“How the fuck is that the best solution? Are you insane?”

“Don’t be such a prude, Mr. Dynamight. You’ve bottomed before. It’s not that different. Have you ever tried it on your own?”

“I fucking hate you.” He replies, closing his eyes and frowning. “No I haven’t. Why the hell would I do something so embarrassing.”

“I know you’re super anal retentive - no pun intended there actually, but can you relax a little? It’s a good solution if nothing else is working. Your dick might be broken but an orgasm is an orgasm.”

“Remind me to never ask you for shit again,”

“I’d love that. Just keep me on payroll. Anyway,” You go back to typing. “I think that should be your first move,”

“How the—are you seriously telling me I should go fuck myself to solve my problem?”

You giggle. “Well it sounds bad when you put it like that. But I guess yeah. I can help pick out some sex toys, maybe, do a little research. If you don’t want to do it in your apartment, there might be a love hotel,”

A blush creeps up against the back of his neck. He covers his face with his hands.

“I’m begging you to shut the fuck up. There’s no,” Another wave of humiliation sets in “There’s no way this is how I’m going about this. Like. Fucking none.”

“The only other option is the good old fashioned doctors appointment, then. Which we can squeeze in over telehealth I think - since you got a check-up pretty recently. Want me to do that instead,”

“Fuck, no. I just,” He groans, feeling the stress make his eye twitch “Fuck.”

There’s a bit of silence and a little typing, like you’ve decided to leave him to his thoughts. Which he doesn’t blame you for, because all things fucking considered - there’s not really any more options. He’s a smart man and even he is fucking stumped. He’s going to have to give into something, eventually. He knows that, but it doesn’t make him feel any better.

As soon as he gets close to giving up, you sit up straighter and give a deep long sigh.

“Hey,” You scratch the side of your face awkwardly. “Do you want me to help you….?”

He stares at you. “With what.”

“With your dick being broken,”

“What?!”

“Don’t yell anymore, you’re giving me a headache,” You express, rubbing your temples. “Look. You need to get off, and you’re probably going to have to use your ass to do it. You don’t want to do it by yourself, and you don’t want to do it with a friend or escort. You’d prefer not going to the doctor's office or taking any pills. I’m offering - I’m not really your friend per se and you trust me enough to ask about it.”

He hates more than anything that you have a point.

“You can’t be fucking serious right now.”

“Hey. If you want your dick to stay broken for a while until you figure it out, do you. I’m just saying. Offering solutions is what you pay me for,”

He pulls back a little.

“...Are you fine with that?”

“Oh banging you? Is that what you’re worried about?” He winces at the direct and crass way you speak. “I like you plenty and you’ve got a pretty face. I’m down if you are,”

“I can’t believe I’m considering this.”

“Really? I totally can,” You snicker, and he really, really considers firing you. “It’s not the first time we’ve crossed boundaries with each other. Just consider it, okay? Before you actually blow a fuse.”

He leans back in his chair and groans.

“Fuck. Yeah, whatever.”

It’s another week before Katsuki takes you up on your offer.

Miraculous it took that long, given the amount he suffered stubbornly trying to fix the problem on his own. The lengths he went too are too embarrassing to even disclose or recount but it very quickly became clear that this was not an issue that was going to magically disappear - no matter how hard he tried.

Against his better judgment and after a long, cold shower trying to talk himself out of reality - Katsuki sent you a one line text.

Fine. Come Saturday.

The only thing he could say without dying of complete fucking shame. He’s grateful that’s the time you decided to have some tact.

(Not a lot, since the text back you sent was a peach emoji and a thumbs up. But whatever, he’ll take what he can get.)

It’s Saturday now, and he’s clean. All of him. He’s clean, and just wearing his boxers - sitting on his couch. You’ll be here very soon, and he can’t believe he’s saying this, but he’s nervous.

You did mention you were fine with it. He believes that because there’s been long standing tension between you two for god knows how long he’s not entirely blind too. You sleep at his place sometimes and spend all day with him, and then there was that one time you two kissed (very sober) during New Years. You don’t bring it up because you know he can’t deal with it. Yet he’s comforted by the fact you at least want it (because you’ve said so), and that you’re willing to do this despite the ambiguity in your relationship.

He knows that is inevitably going to come up today. But he really wants to fucking cum. And if it’s with you, then it’s fine. If his head was a little clearer, he would probably reject this whole thing based on his own emotional disparity. God fucking knows he is not in any place to deal with any of that. His heart barely gets by in the office and now you were going to fuck him.

Is he stupid?

Usually no, but because there’s a soft dick and tight balls where his brain used to be, currently yes. Everything put together, it’s a recipe for disaster. He considers telling you to fuck off and forget all this happens.

But then he thinks about the prospect of your hands and your voice and it’s enough to at least get his heart pumping, though his dick still refuses to cooperate.

More than anything, he does trust you. Shitty, smug little fucker you can be sometimes - there’s not a single person who goes out of their way for him. More than just your job, sometimes it feels like every little thing you do is for his sake. Everything you don’t ask of him, every secret you keep. You push him where he needs to go and encourage him to take risks in his career without imposing on him.

He blushes again, laying on his couch. He was nervous before but it’s not any better. Maybe he’s not so much of a dumbass as he is a total fucking masochistic. Is the level of overthinking the shit Izuku goes through? No wonder he’s like that all the time.

He almost jumps out of his skin when he hears the doorbell ring.

He answers the door shirtless and finds you on the other side. You have a cardboard box and the most nonchalant expression he’s ever seen. Normally it would annoy him, but right now he’s kind of comforted by it. You look at him with a flat smile.

“Hey sexy,” You say with no intonation. “Can I come in?”

He gives you a look of disdain. “Don’t ever say that shit to me again. But come in,”

You laugh quietly as he steps aside. You don’t have much with you other than the ominous box and your bag.

“You look like you’ve showered,” You say, taking your shoes off and putting on the house slippers he keeps for you. You don’t even look at him as you go towards his bedroom upstairs. He follows you with mild (faux) annoyance.“What a shame.”

“The fuck is that supposed to mean?”

“I wanted to get a little romantical and help you clean up but you’ve taken that from me. I’m a little hurt.”

“You’re such a dumbass. As if I’d let you do that,”

“Don’t be such a spoilsport. I’m gonna be playing in your ass today anyway.”

“Not the same thing.”

“Tomato, to-mah-to,” You say with a wave of your hands. When you finally get upstairs, you look over your shoulder. Katsuki gets the message quickly enough, helping you with the door. You give him a little smile and let yourself in, dropping the box on the edge of his king sized mattress.

He stands in the doorway for a short while, glancing at you before coming in. You put your bag somewhere on the floor before getting back to the box you’ve brought over. He can guess what’s in it, but he stands with you to open it anyways.

Predictably, the thing is full of sex toys. The first question he wants to ask is how much you spent on all of it, but he bites his tongue.

You look at him and do a little jazz hands gesture. “Tah-dah.”

He gives you a displeased look, but you’re well used to this sort of thing from him. There isn’t actually a whole lot in the box. The theatrics of you bring it upstairs were more likely just you fucking with him for the sake of the bit. He frowns. Typical.

You do have some new things in the box. A few expensive look gadgets, like a pair of quirk canceling handcuffs (decorated with leopard print fur) and something that looks like it goes around his neck. The sex toys that are in there are noticeably high quality. You definitely used his dime to pay for this.

“Handcuffs? Seriously?”

“You’re too much of a control freak and I like not having my hands blown to bits,” You say, shaking your head. “We should establish some ground rules and stuff now.”

“Haah? The fuck are you gonna do that we need rules.”

“I’m not just gonna jump scare you with dominating you. But that is what I’m doing. What we’re doing.” You give him a more serious look, that makes him feel more shy than he cares to admit. “You get what I’m saying? You have to trust me a little, okay?”

He makes a petulant face at you. “I already trust you dipshit,”

“This and that are different,” You say, shaking your head. He refrains from disagreeing with you a second time. They’re really not, but he has no desire to explain that. “I’m gonna touch you and be a little strict. Are you okay with that?”

“I don’t care.”

“That’s not an answer,”

He grits. “I want to cum. And I…trust you or whatever. I already agreed to this. If it’s pissing me off, I’ll just kick you offa me. Anyway, ‘s fine.”

“If you kick me I’m suing you for battery. We can have a safeword. I’m not going to duct tape your mouth and I’m gonna talk you through most of it - but just incase.” You say. He pauses, taken aback by how… delicately you’re treating him. He doesn’t know if he should be pissed about it or not. “Any word is fine. We can use the stoplight system too if you want.”

“Stoplight?”

“Red for stop, yellow for slow, green for go.”

“That’s fine. Easy to remember.”

“Okay,” You nod to yourself, tucking the promise to memory before looking at him more seriously. “Are you okay with intimacy?”

He stares at you.

“The fuck…?”

“Kissing and hand-holding and all that other stuff.”

“Is it necessary?”

“Strictly speaking, no,” You look at him knowingly this time. He’s taken aback, but you’re always like this. You look through him, not at him. “Are you okay with it?”

The implication is there. Do you want it? is the question that goes unasked. Too direct for his tastes. He feels heat spread through his body, rubbing the back of his neck sheepishly.

“Yeah…’m fine with it.”

Your smile is more genuine this time around. He turns away from you a little.

“Okay. That’s everything out of the way. I’m gonna cuff your arms,” You say. It all feels a little sudden. He figures you’d mean business, but still - he’s not all that prepared. He’s had a week to mentally prepared but that feels like nothing compared to now. There’s an authority to the way you talk now he isn’t sure he’s going to get used too. “Repeat your safewords to me when you turn around.”

He frowns but listens. He puts his hands together in front of him, waiting for you to cuff him, shyness making him hot.

“Uh. Red for stop, yellow for slow down, green for go.”

“Good boy,” You say so smoothly it almost rolls off of him. The cuffs go around his wrists, and Katsuki can feel the familiar sensation of losing his quirk. Now it’s just the both of you. “I’m expecting a little pushback, but generally - you’re to listen to me. Clear?”

“God, fuck - yeah clear,” Katsuki says, feeling ticklish all of a sudden. “All this shitty foreplay is making me feel weird.”

You wrap your arm around his midriff in a sudden movement, making him twitch. He can feel your cheek pressed against his chest as your hands hover over his waistband. He takes in a sharp inhale.

“It’s good that you’re feeling anything.” You say, breath just barely above a whisper. “Gonna take this off,”

He just nods, silently. It’s still on soft, but something is happening in his gut at least. You help him take his boxers down. You’ve probably seen him naked before, more than once. You two being attached at the hip was no joke. This time there’s this lingering anticipation that’s there, and that changes things.

He steps out of his boxers. He’s naked and you’re clothed and his head feels like it’s spinning. Your hand guides him to the edge of the bed. He sits and watches you, but you don’t undress.

The first kiss (second kiss) that you exchange with Katsuki is pleasant. You bend down to do it. It’s a chaste way to meet his lips, weirdly soothing while his stomach is starting to tie in knots. It’s a little surprising how..comfortable it is. Your mouth is soft, your lips taste a little like chapstick and you smell nice. You pull away to kiss the corner of his mouth, trailing down his jaw.

Your thumbs draw over the shell of his ear, rubbing the lobe tender. You’re so different. The contrast in your normal personality is a little too much for him to reconcile with easily, but you brush over these things well enough. He looks away when you meet his eyes.

“Do you wanna lay down or kneel?”

His throat is tight. “...Don’t care.”

You laugh a little to yourself, another kiss. “Lay down then. It’d probably be easier if you put your ass up but knowing you, I doubt it.”

He blushes, annoyed that he’s so obviously predictable to you.

The sheets are soft where he lays. You don’t join him on the bed at first. He just waits there cuffed as you shuffle around for things - lubes and toys and pillows. When you do return to him, you pat his side and slide a pillow underneath his back. He quickly regrets laying down, because god the position is fucking exposing.

You get between his legs and settle there comfortably. A hand rests on his bare thigh, rubbing your thumb into smooth, muscled skin. His breath is hitched. You lean down and kiss his hip. Still no dice on the erection, but you don’t seem discouraged.

You flip the lube open and let it pour onto your fingertips. It’s pink lube. This is mildly irritating, but saying anything will feed into your satisfaction so Katsuki bites his tongue. He watches it as you warm it in your hands, patting his leg with your clean hand.

“Legs up,” You instruct. “And deep breath. Try not to tense.”

“Just goin’ for it, huh?”

You don’t reply to that, but you do smile.

It’s not his first rodeo. His second or third, but certainly not his first - but he’s never had it done for a reason like this. There was an exchange prior, that someone was putting something in him for their pleasure too. This isn’t for that. This is just for him, with your skilled hands and your oddly gentle tendencies that he doesn’t see any other time. That proves to be too much, makes his belly feel honeyed with lust.

The warm, thick sensation of lubed fingers presses against the tight rim of muscle. He breathes and unclenches. Tries not to think too hard about anything. He’s desperate, too desperate. At this point, it’s hard to be prideful. Your hands are noticeably daintier than the ones he’s had in him prior. It’s…weirdly nice. Makes the process easier somehow. He’s reminded that you’re just you, and that makes him more nervous.

“That’s it, baby,” You hum, so soft it’s startling. The way the blood starts to rush in that familiar way nearly makes him sick. Oh, fuck. No way. “Oh?”

No way. No fucking way. No way that’s what does him in.

You pause. He takes in a deep breath, ready to say anything to defend himself. Humiliation spreads through his whole body. He can feel how hard he’s starting to burn, like the blood in his body is struggling to keep up with the desire and pump of his heart. His chest and face start to flush a familiar rose as he grits his teeth and closes his eyes.

Weeks. Weeks and weeks of trying to figure this out. And it was you calling him baby, of all things, to get him at half-mast.

He’s too afraid to open his eyes, but forces himself too. He’s expecting a smug laugh or sarcastic jab but instead you just look surprised. You stare at him, unblinking. He’s so startled he stares back.

“Do you wanna…keep going?”

He gets hard. Fuck.

“S-shit,” He says, wishing he could cover his face with his hands properly. “Yeah,”

He can’t read your expression at all. Annoying. You don’t brush over it though - but you don’t force him to acknowledge it either. Maybe you’re just focused on the fact he finally has something to work with and don’t want to ruin it by making him talk about his feelings.

“Baby,” You say again, smooth and deliberate. There’s that twitch again, something pooling in his gut. He starts to feel nervous. You’re doing the same as before, stretching him and teasing the rim - getting him ready for something else. “You like bein’ my baby, Katsuki?”

He opens his mouth, only to close it again. He tries to choke some word about, telling you go fuck yourself - but he always ends up looking at your face. Your lashes on your cheek. Soft touches and even softer words. He stops knowing what he wants at some point.

“Ugh,” His voice grows thicker. “Don’t ask me that,”

(If he were more apt at honesty, he could admit to you that he just wants you. In whatever way. Sometimes you get like this, when you’re not screwing around - and you’re so good to him that it hurts. He likes your sarcasm and dryness.

But he likes too when you’re this sweet on him too - even if that feels shameful as fuck. That feels like it’s crossing so many more lines that you’re usual self. He knows that better than anyone. It is crossing more lines than usual.

He can’t help but think about it anyway.)

You laugh a little. His eyes go lidded as you continue to work him open. It’s a slow process. You circle his hole with your thumb each time before pushing in. You get one finger in without effort. The second one takes a little more. Another heaved breath and unclenching of his muscles.

He hasn’t felt the sensation of something entering him in so long. He can’t remember when the last time was. He’s antsy as you pump your fingers in and out, stretching him slowly. You find the bottle with your free hand, flicking it open with your teeth and pouring lube onto him directly before you keep going.

“That feel okay?” You mumbles

“Y-yeah. Feels fine,” He huffs, closing his eyes “Feels…good,”

“It’ll feel better soon. Just need to,” You curve the two fingers inside of him up. They search and search and search until—

There. Shit, there.

“Oh, shit,” He gasps, arching himself up as you rub it. You smile at him, pleased. “Fuck,”

You whistle. Katsuki can feel his cock throb properly now, up at full attention. You don’t touch him though. Your other hand grips his thigh for support as you focus your wrist and energy on curling your fingers against his prostate. His stomach flutters, waist tightening.

He’s been fucked before, damn it, but this is different. This is controlled and concentrated. Your fingers are perfect in their motion, pinpoint pleasure making him break out into a feverishness. You’re annoyingly good at this. His whole nervous system feels like it’s being unraveled so slowly. Pulled apart like the slices of a fruit, something for you to pick off and eat.

His head feels like it’s full of cotton, tongue too big for his mouth. Thoughts clouded and inhibition lowered. Real pleasure. He hasn’t felt that in what has to be more than a month now. It’s overwhelming. He’s sensitive and muddy and acting stupidly - he’s well aware. It’s an out of body experience being so unwound in general but this after everything is overstimulating.

God it feels good. How can anything feel this fucking good?

His breathing is erratic, heart pumping trying to keep up with it. Euphoric little pricks start at his abdomen and shoot off through his whole body. Like the splintering ends of a falling star.

He’s never had any orgasm that feels like it needs every muscle in his body to pump through him. It starts in his center and spreads out, melts him slowly. Usually the feeling of needing to cum is passing - just building pleasure until the orgasm hits and the high relaxes. His cock is leaking now with every little press along his insides. Little white dribbles of pre-cum sliding down his shift all the way down to his ass. He doesn’t want to think about how he looks, so he focuses on how it feels.

“Fuck, that feels so good,” His voice almost gives. “Shit, I’m gonna cum if you don’t slow down.”

“You can cum if you want to, Katsuki,” As if to drive the point home by massaging his inner thigh, neglecting his cock “Guess you’re pretty sensitive inside, hm? Gonna make you cum like a girl,”

His blush deepens..

“Haah, fuck - fuck I’m not sensitive. It’s just, hng. Been a while,”

“Don’t be a liar or I won’t let you cum,” You tease.

His eyes shoot wide, brows touching his hairline. “Fuck, d-don’t you dare. .”

You have the nerve to laugh at him. All things considered, maybe you’ve earned. “Just teasing. I’m awful but not that awful. “

“You’re not awful, fuck - just really,” He throws his head back against the sheets. “Need to cum, really need to—”

“Gonna cum without even touching your cock,” You say, half-amused. He shudders when the realization dawns on him.“You’re so sweet.”

He’s drooling. The strength goes out in his jaw as the feeling just builds and builds and builds. It goes on like it’ll never topple.

When it does, it doesn’t feel so much like a rope unsnapping as much as it feels like everything is being pulled from under him. Like the loss of gravity. His abdomen goes tight, the anticipation of it making it impossible to breathe. So close, so close, so close. His brain feels shut off, mindlessly humping along air to capitalize on everything. You’re encouraging only eggs him on further. He lets out a garbled little noise, choking. His voice rasps as electricity flows through him.

And he cums, there’s an orgasm - but nothing comes out. He cums so hard but his balls still feel so tight and full. It feels good but he’s still so fucking hard. It snaps him awake as his eyes open, and you’re staring at his cock a little awestruck.

“Oh, poor baby,” You say - not exactly mocking him but not exactly being kind either. Katsuki stares at you lost and hazy. “A dry orgasm after all of that. That’s just cruel.

He heaves. “What the….how am I supposed to?”

His dick aches. Fuck he almost wants to cry.

Your hand wraps around the base of his shaft in a sudden movement, making him hiss. He almost cusses you out. Sensitive, too sensitive. You put your thumb over the tip of his cock, more pre-cum leaking from it as you. You look mesmerized as it dribbles against your thumb

A long pause.

“Hey,” Your expression is serious. “Do you wanna fuck me?”

“What?”

“I’m really turned on right now, shit. I was planning on just helping you but, you didn’t cum yet and I’m...,” You’re looking at him so directly. His heart pounds. “You can say no,”

Of course he wants to fuck you. That’s what he wants to say. He doesn’t know where he’d find the fucking gall.

“....’s sensitive,” He says instead, flushing with embarrassment. You brighten up. “Just… give me a minute,”

“I will but first,” You rummage through your items and pull out a plug. His eyes widen. “It’ll feel good, I promise.”

He grumbles, but doesn’t reject you. You have some kind of miracle in you - so he feels more inclined to just give in to whatever you say. You look eager to do it. He doesn’t know how he feels about that.

It’s easy enough to put the plug in when he’s already all soft. He’s still sensitive and swollen. He hisses as the cool metal of the plug slides into softened hole, before settling. You give him a little tap on his which he glares at you for. Your only response is laughter.

There’s nothing to talk about while Katsuki watches you undress. You don’t take it all off - just your bottoms. It’s not that he has nothing on his mind. Just that… seeing you like that isn’t making him any less hard. He just… looks at you. Dumbly. You slide your shorts off in one go and your underwear along with it, and you’re all on display.

It’s pretty. Your pussy is really pretty. A horrifyingly embarrassing thing for him to think but it’s true. There’s a fine layer of hair on your mound that he likes. You’re dripping wet like you said you were, and that doesn’t make the situation any easier. You give him a little smug grin as you settle over his lap. He stares at you completely absent-minded, flushed.

“Like what you see?” You tease. He’s too struck to lie to you.

“Yeah,” He rasps. He’s out of his mind right now. He blames it on his dick. “I wish I could take these fuckin’ cuffs off.”

You look at him a little surprised. “You don’t like being cuffed and restrained?”

His ears feel hot, heat prickling up his skin. “Didn’t say that just,” He groans even trying to say it. “...Wanna touch you,”

He trails off. You use your hand to turn his face back to you, cupping his jaw as you bend forward to kiss him. He stares at you wide-eyed, making a noise of surprise. This kiss is different from all the others. Deeper, with more feeling. He gets into it, lifting his head to kiss you back.

When you pull away, you’re all fluttered lashes and adoration.

“After I drain your dick dry,” You say with a confidence that astounds him. “I’ll take them off and let you fuck me proper. But you have to tell me you want that, first. Do you wanna fuck me, baby?”

“Shit. Y-yeah,” He nods, feeling absolutely swept up in your pace.

“Say it.”

“I wanna fuck you, dammit,” He stutters through the last of his sentence. “Don’t make me beg, my dick is going to blow off if you keep torturing me.”

You laugh good naturedly and he feels a little proud that he made you laugh. The thought that he’s beyond whipped wipes the smile off his face completely, but whatever.

You pull back, sitting up as you examine his cock. You hold it up to you, weighing your options.

“I’m too horny to open myself up. I’m just gonna sit on it, ‘kay? Don’t buck your hips up,”

He opens his mouth to protest, but the words die in his mouth. The warm, wet heat of your cunt is immediately overstimulating. He groans so gutterally it startles him. Like it’s punched out of him. This is the only pressure his hard cock has gotten in months and it’s making him feel like he’s on fire.

You don’t give him a chance to cover. You lean over him as you maneuver his cock to your entrance with all disregard for his sanity. You hiss as the tip finds the spot. Fuck you’re wet. Your insides are so soft, so sticky - but you’re still so damn tight.

As you promised you go slowly. It doesn’t help him losing his mind. Worsened by the fact he can see you on top of him, all bated breaths and shaky moans. There must be a dull pain, but you only give him a smile as you get the first inch.

“You’re big,” You say breathlessly. His cock twitches to life. “Feels fucking good. Shit, that’s amazing. Haha, I can feel you so deep already.”

“Please stop talking, before I, haah,”

“Don’t cum yet,” You demand, lowering yourself further and further until you’ve bottomed out. Katsuki feels fucking crazy. “Let me get my fill first.”

“Ngh, easier said than fucking done,”

You just laugh. “Try your hardest, Mr. Hero. Show off your endurance, hm?”

He groans as you start to move. You really don’t regard him at all. You lean over him with one hand and use your other to tease and toy with your clit as you ride his cock with reckless abandon. The room is quick to fill with noise - the sound of skin slapping skin, the skin sticking where your hips meet his thighs.

You’re moaning in little broken waves. He’s not going to last if he listens to you anymore.

He’s biting the inside of his cheek trying not to cum, but you don’t make it easy. You’re riding him with so much force, using him. Your pussy is so tight it’s gripping him, sucking him dry. A vice-like grip, sticky and pliant over the hard curve of his cock. Everytime you bounce and throw your ass a little harder onto him, he can feel you. Feel himself and how deep he is. His hands tighten into fists where they’re cuffed in front of him.

He’s never been… used like this. But he doesn’t hate it the way you disregard him to chase your own pleasure while being so generally mindful of his own. You take and take and take but you make it feel so good.

It’s not helped by the plug in his ass, brushing against his prostate every single time you move. Makes him jolt. Every fiber and nerve in his body is wound as tight as it can possibly go. All of his strength, sanity, and focus he has left in him is trying not to cum, not to buck his hips up and rut into you like a stupid animal no matter how much he wants too.

He can feel you start to cum before you even tell him. Your walls pulse with need and your movement starts to get slower. The grip you have holding you up weakens slightly.

“Gonna cum. Fuck baby, I’m gonna cum,” You say with a pant. You open your eyes and look down on him “Cum with me, okay? Don’t hold it in,”

The words alone trigger a reaction. But with everything else, it’s like Katsuki explodes. Weeks worth of tension in his body, in his muscles, in his everything - burst at the seams. You cum and he follows you nearly in succession. The hard pulsing of your swollen cunt suck around him like a vice and he goes practically limp feeling his dick finally drain.

He cums and he can’t stop cumming. Pumps out so much white hot seed his head starts to cloud. He fucks up into you, sloppy and dumb. Chasing his high as he pours every ounce of his load into your pussy without so much as a modicum of shame. A month of dryness overwritten by the most intense orgasm he’s ever had in his fucking life. He doesn't know how long he stays there, painting your walls with his spend. It just goes on forever, longer than he’s ever experienced.

He has his eyes closed as he goes limp. Fucking hell.

It takes him a while to go soft again. When he finally does and returns to consciousness, he’s still nestled inside you. You give him a smile when his eyes finally open, leaning forward to kiss his hairline.

“Still all there?”

His voice is hoarse like he’s been screaming. “I feel like I fucking died,”

You giggle.

“So… no?”

“Kind of. Barely. What the fuck is up with you.” He says laying his head back, sweat dripping down his back. “Shit.”

“Did you like it?”

He gives you an unimpressed look as you laugh.

“I’m glad.” You say softly. You’re warm. God he’s down bad. “We have a lot to talk about later. You should take a little break for now.”

He nods in agreement to both things before pausing. “For now..?”

“You thought we were done?” You say with a tilted head. He gapes. “I thought you knew I was more ruthless than that.”

He groans.

“You’re insane.”
