Work Text:
There’s a knock at his dorm room door.
Shouto doesn’t have to turn to look at who just walked inside. There’s no one else who would come here uninvited at this hour except for one person.
“What’cha doin’, shortcake?”
Shouto’s mouth quirks up into a smile at the nickname, somehow, it never fails to get a reaction out of him, no matter which name his boyfriend calls him.
“I planned to watch that documentary on snow leopards I sent you. Do you want to watch it with me?”
Katsuki shrugs, hands buried in the pockets of his sweats – a pretty obvious attempt at looking ‘cool and unbothered’ if Shouto’s ever seen one – before he plops on his futon. Shouto set it out with one side against the wall, then aligned an array of pillows and throw blankets to lean onto. He sort of suspected that his boyfriend was going to come up to his room, if the threat from earlier ‘don’t make plans for tonight, pretty boy’ had been anything to by.
It’d become their little habit over the months they’ve been dating – meeting up at one of their dorms to spend the evening, or the night, together. It’s nice to finally get some time with Katsuki, just the two of them, without any of their other friends there to interrupt them.
“Move over, halfie.” Katsuki grumbles, unnecessarily pushing Shouto as he shuffles in between the soft mountain of pillows.
“There’s enough room for us both, you don’t need to push me.”
Shouto pushes him back, makes sure to not be too rough so Katsuki’s head doesn’t actually hit the wall, but enough to get him to fall on his ass before he can properly settle himself down.
“Oi, you’ in the mood for a fight, Shouto?” There’s a warm hand gripping his wrist now, pulling him closer until they’re nose to nose.
This is how Katsuki intimidates his opponents, brings them close to those fiery ruby eyes while he bares his teeth at them, nostrils flaring like he’s puffing out smoke. Kind of like a wolf who’s trying to assert dominance. Shouto will keep that in mind, maybe they’ll watch the wolf documentary next time.
“Mm, maybe later. I didn’t do my stretches.”
“You-“ Katsuki sputters out, “fuck how I hate you, halfie.” then breathes the words out against Shouto’s mouth. They meet for a chaste kiss.
Shouto chuckles, feel the rumble of his laughter roil through his chest, up to his shoulders, tumbling out past his lips. “Yeah, I know.”
It’s not true, but Katsuki’s always found it harder to express his feelings through words, at least when it didn’t come to expressing how much he wants to blast off someone’s face. Shouto lets him, lets Katsuki call him names, shake him around, maneuver him until he’s satisfied with the position they’re in, because he knows this is how his boyfriend shows his affection for him.
This is Katsuki’s love language. And Shouto’s been studying it way before they started officially dating.
Shouto ends up with his head on Katsuki’s chest, arms looped around his waist and legs thrown over his lap – the best seat in the house, if he’s ever asked to pick one. He doesn’t bat an eye when he hears the whispered ‘fucking clingy idiot’, placated by the following kiss on the crown of his head.
“Comfy? Can I start the video, princess?”
His voice is bordering on condescending, like he’s exasperated with how sticky Shouto’s body becomes once they’re in close proximity – and he glues himself to Katsuki for as long as he can – but there’s fondness dripping around the edges, and the way he pulls Shouto even closer is telling enough. He likes the contact.
“Mhm, I’m good.”
Katsuki presses the space button on Shouto’s laptop and the documentary starts playing. It’s entertaining enough, to Shouto in particular given the interested he picked up on big cats, and cats in general, a few years ago. It’s even better of a watch because he’s watching it with his boyfriend, who seems to be just as invested.
They’re halfway through it when Katsuki starts fidgeting. He untangles one hand from where it’s been combing through Shouto’s hair for the past ten minutes to push his own hair back, then wipe his forehead with the back of it.
“Fuck, s’too hot in here.”
His boyfriend tends to run hotter due to his quirk, and the multiple pillows and fluffy blankets on Shouto’s futon, paired with a body that’s practically coiled around him like a snake, might not be of help.
“Want me to use my quirk?”
“Nah, let me just- I’ll take off my shirt. Gimme a second,” Katsuki mutters, straightening his back and pulling himself out of Shouto’s grip.
His tank top comes off, revealing tanned skin and a chiseled abdomen. Katsuki’s chest is soft enough to serve as a comfortable pillow, but Shouto doesn’t know if he’ll be able to rest his face against it without getting too hot himself. The grey sweatpants are hanging low on his boyfriend’s hips, revealing the black band of his briefs and the fluffy tuft of his happy trail.
Shouto finds him so unbelievably attractive.
And it’d be the simplest things about Katsuki. Like the small mole he has under his left eye, most visible when Shouto’s up close and personal with him, when his boyfriend is too sleepy to chide him for being ‘too fucking sappy’ and he has free reign to kiss all over his face. Or the way older black shirts fit now around his broad shoulders. The way he smells after a shower, or when he’s just sprayed himself with cologne, before meeting Shouto in front of the dorms for a date.
Just, so Katsuki, that it makes Shouto’s mind spin and his heart rattle in his chest.
“Thought you didn’t like your room to be a fucking sauna, Shou.” He doesn’t, but Shouto figures the way their bodies were so close to each other to be responsible for the heat.
“Maybe it’s the blanket, I have it for when I overuse my right side during quirk training.”
“Hmm, maybe.” Katsuki settles back against the pillows, spreading his legs as much as he can. He raises one arm and gestures for Shouto, “I’m better now, c’mere, baby.”
He doesn’t know what it is, but there’s something so hot about the casual confidence Katsuki exudes when it’s just the two of them. It makes Shouto’s entire body tingle from one end to another in the best way possible. With a thumping heart, he settles in the hold of Katsuki’s arm, head resting on a firm shoulder.
His hand returns to its spot around Katsuki’s midriff, but on its way, Shouto grazes his stomach, feeling it jump at the delicate touch. His boyfriend’s abs clench at that, mismatched eyes unable to tear away from the sight. There’s no need to shy away from touching his boyfriend, so Shouto rests his hand there and starts rubbing small circles with his thumb into the skin.
Shivers climb up Katsuki’s back, he can feel them, but the way he settles more comfortably against him tells Shouto that he doesn’t want him to stop. Small motions with his thumb turn into full-on hand caresses, because Shouto can’t seem to help himself around his boyfriend.
Maybe Katsuki was right when he called him ‘goddam insatiable princess’.
By now, he’s moved his attention from the screen in favor of looking at his boyfriend. Katsuki’s body has changed so much over the years, until it fit just the right and optimal way for his quirk. His waist is narrow, but he has broad shoulders and powerful thighs. With a full chest and arms strong enough to bench Shouto (who’s still got a few inches over him in height), Katsuki might just be molded by some higher deity.
There’s no other explanation, when Shouto feels this attracted to his physique. And not just that, but there are times when he allows himself to indulge in the more superficial benefits that come with having a relationship.
“You’re not paying attention, princess.” Katsuki quips, voice lilting above him.
He’s been found, but there’s no potential threat. Katsuki’s palms aren’t sparking with explosions, so it’s a good sign.
“We can watch it later. Or tomorrow. I think I want to do something else, Katsuki.”
His boyfriend snorts, and his abdomen moves along with the exhale of breath. Shouto’s gaze is pulled upwards.
“Really now? And what do you have in mind, baby?”
Without responding, Shouto shuts off his laptop and pushes it to the side. They’re now bathed in the moonlight darkness, the only light being the warm amber glow coming from the lit candle, one of the many scented ones on his desk.
Immediately, Katsuki’s pupils widen, due to the lack of lighting, but Shouto likes to believe it’s just because of him. Katsuki always looks this way at him, like he never wants to look away ever. Like Shouto’s his best fucking view and someone would have to tear his gaze away before Katsuki dares to look somewhere else.
When he settles back in his spot, sitting with his body angled towards his boyfriend, Shouto feels two firm arms grip him by the hips. They’re not pulling or pushing, but simply hold onto him like they need some sort of leverage. Or just because he knows how needy Shouto gets when Katsuki squeezes him like a stress toy.
“Just, sit there and let me touch you.” He says, tongue coming to lick at his lips, hand settling back on Katsuki’s skin.
“Demanding,” His boyfriend teases, but the grin on his face doesn’t falter.
He likes this, Shouto concludes.
It shouldn’t even surprise him, Katsuki’s always liked it when all the attention is on him. Although, there are times when he hates being under the spotlight, but he’s told Shouto even times before – and pulled him by the chin to lock their eyes – that he likes it when Shouto looks at him.
When he looks at him like that.
“Like you wanna fucking devour me, princess”, he’d said, when Shouto asked him ‘how am I looking at you, Katsuki?’.
A cold hand trails up and down his abdomen, fingers dipping in the grooves of Katsuki’s abs, then up to his sternum. Shouto doesn’t miss the way Katsuki smirks at him when his hand hovers over one of his pecs, and just because he’s a little shit – Katsuki’s words exactly – he squeezes it, teeth sinking in his lower lip when it bounces back in place as soon as he lets go.
“You’re really handsy tonight, Shou.” The blond reprimands him, but he sounds more entertained than anything else, really. Shouto decides to continue.
His hand flies back down to the soft trail of ash-blond hair like it’s calling to him. He rubs his hand over it, fingers skimming along the waistband of his boyfriend’s sweatpants.
“But you like it. You told me yourself, you like having my hands all over you, Katsuki.”
Katsuki pushes his hips up into Shouto’s touch when the latter’s hand bumps lower into the tent forming at the front. He bites back a groan when Shouto doesn’t follow through with his ministration and goes back to tracing mindless shapes over his stomach.
“Are you going to just tease me tonight, princess, or are you planning on giving me more?”
Shouto hums, then brings his other hand to cup the side of Katsuki’s jaw. “You’ll have to convince me then.”
Katsuki kisses him, wastes no time in licking his way inside Shouto’s mouth. Traces his lips until they’re strawberry pink and then rubs their tongues together, just to hear Shouto keening like the spoiled pretty boy he is.
He grabs Shouto’s wandering hand and brings it up to his mouth to kiss the middle of his palm, while his own free hand pulls his sweatpants down enough to free his erection.
Shouto catches on, and soon enough he’s got the same hand wrapped around his boyfriend’s hard cock. Just like the rest of his body, Katsuki’s dick is attractive to Shouto – attractive enough to make him want to have inside him an unhealthy amount of times. Thick enough for his fingers to barely meet when he encloses his palm around him and long enough to hit that very spot inside him that has Shouto seeing starts behind his eyes.
There’s a vein on the underside of it, pulsing in time with the heavy rise and fall of Katsuki’s chest, and when Shouto rubs against it just so- “Fuck, princess-“ he’ll get that look out of his boyfriend. With the eyes closed and shiny plump bottom lip trapped between his teeth. Head thrown back and abs flexing like he’s preparing to take a punch to the gut.
“Kiss me again, Katsu.”
“Then c’mere, princess. You keep getting mouthy with me, halfie. I’ll have to shut you up somehow.”
Shouto smiles satisfied against his mouth when they meet for another sloppy and passionate kiss. Katsuki licks his mouth like he’s licking a popsicle and Shouto opens up like a flower in full bloom, fuck why does it feel so good kissing him? It feels like his head is full of Katsuki Katsuki Katsuki, and no other coherent thought is able to come through.
The jerking of his hand is out of rhythm, mostly because of how pliant and needy he goes in his boyfriend’s arms, but Katsuki doesn’t seem to mind. He chases each of Shouto’s strokes with great vigor, fucks into his hand until he’s dripping precum all over the inside of his thighs and the back of his fist.
“Katsuki…”
“Yeah, baby? What is it, Shou?” Katsuki’s barely touching him, but he’s talking to Shouto like he’s the one who has him by the dick, not the other way around.
“Want it inside me. You feel so good, Kats, I like you so much-“ Shouto mouths the words over that special spot on Katsuki’s neck, then climbs back up to kiss him again.
He should still be loose enough from when Katsuki fingered him this afternoon in the showers, they really shouldn’t have fooled around in the locker room showers, but they were the last ones to finish for the day and Katsuki offered to shower together so- Shouto couldn’t refuse.
He also tends to lose any filter he’s had on his mouth when they’re together like this. Blabbering off about how much he wants Katsuki inside him, on top of him, under him, anywhere really. As long as he’s touching Shouto in that way he knows how to get him to scream his name and come undone in a matter of minutes.
“I need to prep you first, Shou. How do you want it?”
Shouto clambers in his lap, not before tugging his own sweats down to his mid-thigh, enough to uncover his ass and for Katsuki to have enough room to loosen him up. With two lubed fingers, his boyfriend starts stretching him, caressing his inner walls to make room for himself. All the while, he’s not taking his eyes off Shouto.
He’s jerking Katsuki off with both hands now, because as much as he’d like to fuck himself back on his fingers, his boyfriend’s cock is hot and fat and bobbing over his stomach with precum still dripping down the length- Shouto really wants it inside him. Like, right now.
“Fuck, you’re still so loose, princess. Almost forgot how tight you get when we go a few days without fucking.”
“Put another one in, Kats, I can take it.”
Their foreheads are pressed together and the air around them is hot and humid. Perspiration glides down the back of Shouto’s neck, a few drops sliding down the valley of Katsuki’s pecs- Shouto has to lean down to lick them up.
A third finger is pushed in alongside two other digits, and Shouto’s so hard that he thinks he’ll explode. He’s clenching around his boyfriend’s fingers in a poor attempt at taking him inside even deeper, locking him in, but it’s still not enough.
“You’re getting needy, shortcake. Think you can hold off until I get my cock in you, Shou?”
Shouto nods his head, feels the way their foreheads rub together at the gesture. He also feels a stray kiss on one of his cheeks, which only serves to amp up the flush on his face.
“I can take it, Katsuki. Want you inside, you didn’t fuck me in the showers today.”
“We didn’t have lube, baby. Don’t wanna hurt you.”
“Could’ve used spit. Your fingers didn’t hurt.”
Shouto pouts and insists, but he knows he’s being unreasonable. The stretch of Katsuki’s fingers is significantly lesser than the girth of his cock. But sometimes he gets needy and way too horny for his boyfriend that the idea of taking Katsuki in without any prep might start to sound appealing. At least to a lust-drunk Shouto.
“Fuck, you’re already gone for it, Shou.” A sweet kiss to his lips follows his boyfriend’s admission, “How’d I land myself just the perfect boyfriend, huh? Tell me, Shouto.”
But he doesn’t even wait for Shouto to respond, just rams his fingers inside and gets him to whine out loud as he’s getting finger fucked.
“You gotta be quiet, Shou. I know my fingers feel good, but we don’t want the extras to hear how good you sound when I get my cock in you, princess.”
“Ah ah- asshole…” Shouto grits out between cut off moans, but pushes his ass back onto his fingers.
“Think you’re ready?”
“I’ve been ready for ages, Katsuki. Put it in.”
There’s a laugh bubbling out of him, and despite how horny he feels, Shouto finds himself chuckling as well. “Damn sassy half and half bastard.” He pulls his fingers out of Shouto, then lathers the lube on his dick, “Alright, how do you want it? Wanna sit in my lap just like this, princess?”
It sounds good, but Shouto had a different position in mind. It’s not his go-to position, because most times he likes to face Katsuki when they make love. But there’s something about it when they do it this way – Shouto on his knees, barely supporting himself with his arms while Katsuki takes him from behind – that gets his coming faster than any other time.
It’s also a good angle to get his boyfriend’s cock as far deep inside him as possible.
So Shouto gets off and moves to sit on his knees, leans forward until his head is nestled on his crossed arms. When he looks behind him, he has to bite his smile at the obvious twitch of Katsuki’s cock.
“C’mere, baby.” He repeats his boyfriend’s words to him, even sways his ass from left to right to entice him.
Not that there’s any need for that, Katsuki would do anything Shouto asks for in bed. He even said it out loud, ‘I guess, as long as it’s with you, I don’t mind trying just about anything. Nothing too out there, ‘kay, Shou?’.
And when he slips inside, so fucking slow like he’s still afraid he’ll hurt Shouto in some way – gentle, like he was with Shouto on their very first time, and continues to be, just with him – Shouto feels complete. It might sound foreign after so many years of not knowing how this feels, this raw affection, this never ending adoration for someone.
But now he knows. He knows that it feels like morning kisses sneaked in during breakfast; like neatly packaged bentos; like their own inside jokes that no one else gets but them; like the tight embrace of a lover; and just like the way Katsuki fits so perfectly inside Shouto.
Like they were made to go together like this.
Made for each other.
When Katsuki leans his body over him, covers Shouto whole until his chest is plastered against his back, and kisses all over his neck and shoulders, he’ll lose the grip he had on his elbows. It always goes like this, with Shouto thinking he can hold himself with his arms while Katsuki is practically plowing inside him with deep thrusts, but this isn’t about stamina or core strength.
This is about how much Shouto’s heart – and ass – can take. Katsuki never minds the fact that he has to hold Shouto up. He twines his hands over his front and holds both of them up, while still fucking inside him at a steady pace.
Shouto will go from raining praise and pleas to moaning out his name, because after the blunt head of his cock finds his prostate, there’s no more forming actual words. Anything that’s not Katsuki’s name is forgotten, and all that comes out is a garbled mess of mewls and whines.
Instead of chastising him for being loud again, Katsuki grips his chin and brings their mouths together, swallows all of Shouto’s noises all while they become one, a tangled mess of limbs and hearts over ruffled sheets.
“You sound so pretty, Shou. Look so fucking pretty, princess. All mine, yeah?”
“Mmm, all yours…”
He’ll bring one hand down to stroke himself to completion, only to get it pushed to the side so Katsuki can fist his dick and pump it in times with his thrusts. He always takes great pride in making Shouto orgasm, so he lets Katsuki do whatever he pleases with his body.
“Wanna keep you forever, sweetheart. Will you come for me, pretty boy? Show me how pretty you look when you come.”
When he comes, it’s a hazy mess of choked off moans and the all-too familiar feeling of liquid heat being spilled inside him. They probably should have used a condom, as it will, no doubt, drip all over his sheets, but Katsuki feels to good like this for Shouto to care too much about having to clean after.
Katsuki won’t let him go until his breathing returns to normal, holds him close to his chest without pulling out. Shouto knows he’s hot, too hot, and so he cranks up his ice quirk to cool them down a bit, lest his boyfriend blasts a hole through his futon. Despite feeling like a ticking bomb, Katsuki doesn’t pull away, because he knows how much Shouto loves to cuddle after they make love.
‘I like holding you close. After I come, I feel too exposed. It’s good when you’re here with me.”
“Yeah, me too, Shou.”
They’ll pull apart and clean themselves eventually, maybe even sneak downstairs for a shower. But Shouto feels too comfortable to move right now, so he squeezes Katsuki closer to his chest and breathes him in.
“Don’t you dare fall asleep on me, Shou. We gotta clean you up.”
“Mm, but I’m sleepy.”
Katsuki bites his cheek.
“You’re sleepy all the fucking time.”
“I’m sleepier with your cock in me.”
He feels Katsuki twitch inside him.
“Oi, don’t pull that shit on me.” Shouto is almost certain he’ll get flicked in the forehead, only for Katsuki to prove him wrong by sensually licking his ear, then whispering, “Unless you wanna go another round, princess.”
Shouto, despite his best efforts, fails to keep quiet for their second round. Good thing Katsuki’s there to swallow up his pretty moans.
