Work Text:
Katsuki is tired, but not exhausted. Having just come off a brutal shift, all he wants is to find Deku and hear him say ‘Kacchan’ is his dumb voice.
He wants to eat dinner, kiss his husband, then lay down with him for the rest of his evening. He wants his daily dose of Deku-brand affection, and he’s going to get it come hell or high water.
No, he’s not pouting. He just needs to see Deku.
As he approaches the door to their house, he shuffles around in his pockets for his keys, grumbling and swearing under his breath.
Where the fuck are they? He had cleaned up in the agency's showers and he vaguely remembers all but throwing everything into his bag in his rush to go home.
Goddamnit.
Katsuki swings his duffle bag around to his front to rummage around its pockets for his keys. Impatient to finally see Deku again, he grabs and pulls the pockets open roughly, straining the seams.
It’ll be fine, and if it rips then it's a shitty bag anyways.
Sue him, he misses his fucking husband. He went the entire day without hearing Deku’s voice exclaim a sickeningly sweet Kacchan! in his direction or feeling Deku’s rough hands or seeing his stupid ridiculously pretty eyes.
Katsuki didn’t adjust at all to going so long without Deku, and everybody he worked with could tell.
Normally, even with conflicting shift schedules or the occasional separate assignment, he still sees his shitty nerd every couple of hours. But, of course, Deku had today off, and Katsuki forbade him from coming into the agency on said day off.
Good for Deku’s health, bad for Katsuki’s temper. Rest in piece to the interns Katsuki came into direct contact with today.
“Ha!”
His shout echoes a little as he finally grabs hold of his keys, roughly pulling them out of the bag and narrowly missing his face as they swing on his finger.
“Fuck, just get in the goddamn fucking door, I swear to-”
As he shoves the keys into the lock, annoyed with his inability to just fucking open the door already, he hears Deku exclaim his name, muffled through the still closed door.
“Kacchan? Kacchan!”
Katsuki smirks as he hears Deku’s excited voice, followed by the scrambling of feet as Deku rushes to greet him at the entrance. There’s a bang and a quiet ow accompanying the scurrying that makes Katsuki snicker. He can clearly picture Deku running into the corner of the couch, as he’s done it often enough already.
Right as he opens the door and slips inside their house, Deku slides into view, skidding on the wooden floor with his socks in his rush to see Katsuki. He has a huge grin on his face, arms spread wide and slightly flailing to keep his balance.
As soon as Deku sees Katsuki in front of the door, duffel bag over one shoulder, keys in his hand and a growing smirk on his face, Deku rushes forwards, his own grin growing wider. God, he’s a sight for sore eyes. Katsuki had gone without a lot of the right kind of green today and he’s finally, finally, seeing it in all its mussed up and bright-eyed glory.
“Kacchan!” Deku yells in delight, sliding and tripping as he runs towards Katsuki.
He stumbles straight into Katsuki at full speed, slamming Katsuki back against the door and closing it with a bang. He immediately wraps his arms around Katsuki, digging his forehead into his chest and laughing.
Katsuki drops his bag and keys, reflexively catching Deku, breath knocked out of him with how heavy Deku is and the force of their collision.
Jesus, Deku is like a shit brickhouse, he’s lucky Katsuki had the door behind him or else they would both be out on their asses right now. With how fucking stacked Deku is these days, Katsuki catching a running Deku is like trying to catch a steam engine running at full speed.
Still, as he grasps Deku closer, wrapping both of his arms around his back and gripping his ribs with his fingers, the corners of his mouth tip up. He can always count on Deku to never hold back, his joy at seeing Katsuki expressed in every action.
Katsuki squeezes him tighter to his chest, resting his chin on Deku’s head, and Deku responds in kind, gripping Katsuki’s back and waist tighter still. The warmth Katsuki first felt hearing Kacchan through the door only spreads, suffusing him with the same happiness he had heard in Deku’s voice and overcoming the slight annoyance he had felt just a few seconds ago.
“Hey, nerd,” he says, voice soft and quiet. His tone causes Deku to look up from where he had shoved his face against Katsuki’s chest when he fell. Deku meets his eyes readily, the familiar green punching straight through Katsuki’s heart.
Fuck, he loves him, loves Deku so much it physically aches. How dare he do this to Katsuki.
Deku responds breathily, his big ass smile scrunching up his freckles.
“Hey.”
Katsuki squeezes him tighter briefly, before loosening the grip of his hands and arms the tiniest bit so he can properly see Deku’s dimples and freckles. What with Katsuki being a full head taller than Deku, it made seeing his face while they hug harder.
Katsuki loves it and repeatedly takes advantage of it but right now he just wants to see his husband clearly.
Katsuki brings his right hand up to Deku’s forehead, brushing green curls back and continuing the movement into his soft hair. Deku melts into the motion, shoulders loosening and falling into Katsuki’s arms even more. The frantic excitement Deku greeted Katsuki with is still visible at the edges of his wide smile and bright eyes, but it softens slightly when Katsuki gently starts to rub Deku’s head.
“I’m home, Deku," Katsuki says.
“Welcome home, Kacchan,” he answers.
He laughs, the force of his joy squeezing his eyes shut, and presses his head back into Katsuki’s chest, embracing Katsuki’s waist and back again.
It honestly feels like Deku is trying to strangle him with how tight he’s gripping Katsuki, but he doesn’t mind – Katsuki is holding him back just as tightly. When Deku’s laugh vibrates through Katsuki’s body from where it’s muffled against his sternum, Katsuki subconsciously tightens his arms further around his husband’s back, preventing him from moving away.
Something inside of Katsuki is soothed at the sound of Deku’s laugh. He’d gone all day without it and now he gets it as soon as he gets home.
“I missed you today, Kacchan,” Deku says, almost quietly, something like embarrassment lacing his tone and coming out shy, but apparently not embarrassing enough to refrain from saying it.
He follows it up with a kiss to Katsuki’s ring, lips pressing gently where his shirt covers it. It’s at mouth level for Deku, the length of the chain allowing him to quickly shift his lips over to the ring before hiding his face back in Katsuki’s chest.
“Yeah, me too, nerd,” he says, voice rough at the blatant display of affection. He backs his words up with the hand in Deku’s hair pressing him tighter against him, his other hand still gripping around Deku’s waist and ribs.
Fuck, that little kiss just destroyed Katsuki.
“Yeah?” Deku asks.
Asks, as if Katsuki isn’t sure he missed Deku, too. He had only been thinking about him the entire day, of fucking course he missed Deku.
Deku peeks up at him, red dusting across his freckles.
Fuck, Deku is so cute. Katsuki can feel his heart literally skip a beat, the traitorous piece of shit.
He has the sudden urge to grab Deku’s fat fucking dimpled cheeks and kiss him until they both stop breathing. He's needed to punch Deku’s lips with his since fucking yesterday.
Katsuki growls, hands quickly coming up to grip Deku’s face, pulling his face up and away from his chest and uncovering the delicious blush Deku’s trying to hide.
Katsuki’s hands cover both sides of Deku’s face completely – and Katsuki can feel the heat of Deku’s blush seeping into his palms and blood stream, carving a path through his veins to his heart – and his fingers span from Deku’s smooth jaw to the unruly curls on his head. He holds his entire world in the palms of his hands, and he just wants to kiss him already.
“Yeah, dumbass,” he says, speaking low and quick as he leans down. He’s laser focused on Deku’s slightly opened mouth, his pink bottom lip shiny with spit from where Deku had run his tongue over it.
He’s going to destroy this damn nerd and his cute ass fucking face, kiss him until the only thing Deku will taste is Katsuki’s tongue. All previous tiredness leaves him as he descends to where he has Deku’s head captured in his hands.
Right when he gets to Deku’s lips, Deku turns his head away, making Katsuki kiss Deku’s cheek in the small space between his thumb and forefinger.
What the fuck?
“What the fuck?” he repeats out loud, hands slightly loosening in his confusion as he pulls back and stares blankly down at Deku.
Did Katsuki miss his mouth or some shit?
Deku nervously giggles, his scarred hands coming up to wrap around Katsuki’s wrists as he takes a small step back. Katsuki isn’t holding Deku between his hands anymore, Deku’s warmth no longer resting comfortably in his hands or the soft strands of his hair rubbing against Katsuki’s fingertips.
Did Deku just step away?
Deku is still smiling though, little giggles coming out of him as Katsuki looks down vacantly, staring at him in confusion. Deku’s hands tighten on Katsuki’s wrists, squeezing once, and the hallway light glinting on Deku's wedding ring breaks Katsuki from his trance.
“The fuck?” he mumbles, mostly to himself, still staring at Deku and his wide green eyes.
“What?” Deku asks, grinning up at him.
Katsuki’s head is working overtime, all unnecessary thoughts on hold as he tries to compute what the fuck is happening. Deku has never turned away from a kiss before. If anything, he always initiates them the most, attacking Katsuki’s face with an enthusiasm that never fails to leave him hard as fuck.
But, this is new, a situation Katsuki has never encountered before.
Katsuki’s flying blind here; he has no clue what the fuck is happening or what Deku’s little head turn means, but that isn’t going to stop him. Katsuki needs to try again, just to make sure whatever the fuck had just happened was a fluke.
He keeps his hands in Deku’s wrists as he leans down again, a little quicker this time as he aims straight for Deku’s lips. Deku doesn’t move, dumb smile still on his face as Katsuki moves closer to him. At this Katsuki relaxes a little, movement slowing down the tiniest bit.
Wrong move.
As soon as his lips just barely brush against Deku’s, featherlight and so quick he doesn’t even feel them, Deku turns his head to the side, again, stifled giggles sounding in Katsuki’s ears as his lips land on Deku’s cheek, again.
This little fucker!
He tries again, quickly darting down to his lips only for Deku to turn his head to the side at the last second.
Katsuki explodes this time, straightening up with a shout and staring down at Deku as he continues to try and muffle his laughter.
“Hah?!”
Deku finally bursts, laughing at Katsuki’s reaction, and curling down on himself with the force of his laughter. He’s hanging off where he still holds Katsuki’s wrists in his hands, Katsuki supporting all his weight as he giggles uncontrollably, eyes closed and mouth wide open as he laughs at Katsuki’s suffering.
Does Deku think this is fucking funny?! Katsuki wants his fucking kisses! He went the entire day without kissing Deku! The nerd has it fucking coming if he thinks Katsuki is going to wait any damn longer!
“Hey!” Katsuki shouts. “Give me my kiss, you little shit! I want my kiss!”
Deku straightens up a little - still fucking laughing at him, the audacity of this loser - using his grip on Katsuki’s wrists to help pull himself upright. Katsuki lets him, not shaking Deku off him but watching him warily, a scowl still twisting his face.
He lowers his arms until his hands are around waist height to help Deku have a better handle to stand up with, grumbling the entire time.
Deku smiles up at Katsuki, catching his breath.
“Okay, okay Kacchan, you can have your kiss, I’m sorry,” Deku says, laughter still in his voice.
Katsuki doesn’t have the space of mind to admire how fucking gorgeous Deku looks right now, cheeks flush with joy and eyes shiny from the small, infinitesimal tears clinging to the corner of his eyes. He loves him, but by god is Katsuki going to get his fucking kiss, and no one, not even Deku, is going to ruin his nightly welcome-home ritual.
“Damn right you’re fucking sorry, of course I can have my fucking kisses, the fuck you think, fucking – come here,” Katsuki growls.
This time, he darts towards Deku and breaks his hold on his wrists as Katsuki reaches for Deku’s face again.
As soon as his fingertips brush Deku’s face, before his mouth even gets close to his, Deku is off like a shot down the hall, slipping and laughing like an absolute dork as he runs away from Katsuki.
“Deku, you fuck, get back here!” Katsuki shouts, immediately giving chase into their home.
But Katsuki pauses as soon as he takes a single step: his shoes are still on. Fuck!
Katsuki stumbles to a stop with his arms outstretched and touching either side of the wall to stabilize himself as he haphazardly kicks them off his feet and straight into the door before sliding much more gracefully along the floors than Deku.
He can’t see Deku anymore, the few seconds it took to kick off his shoes giving Deku a head start on turning the corner in the hall.
He can hear Deku’s laugh trailing through different rooms and hallways, bumps and bangs as Deku slams into the walls or furniture echoing his giggles and snorts.
Those socks are going to be Deku’s downfall and Katsuki’s victory.
“No!” Deku yells back, denying Katsuki his kisses. His voice has a slightly tinny quality, not too muffled or far away from where Katsuki currently is.
Deku’s heading towards the kitchen.
A terrifying smile takes over Katsuki’s face, promising death and fires and crying babies as retribution for Deku’s little stunt.
Ha, I fucking found you, shitty nerd.
“Give me my kiss, Deku!” he shouts.
“No!” Deku yells back, glee in his voice.
“Give me my goddamn kiss, nerd!”
“No, Kacchan!”
“I want my kisses!”
“No!”
“Deku, I swear to fuck if you don’t give me my kisses right now-”
“Get them yourself!”
“Deku!”
“Kacchan!” Deku gasps out his name, hiccupping and laughing as he continues to run away.
He’s sliding and bumping into literally every wall of their home with all the coordination of a baby deer, making Katsuki curse and swerve as he almost trips over a stool Deku knocked into. If Deku brains himself before Katsuki can get his kiss, he’s going to kill him.
They yell back and forth, Deku unknowingly playing Katsuki’s deranged version of Marco Polo.
It’s all going according to plan, Katsuki treating his need for Deku’s stupid kisses with the same level of urgency and importance of a high-stakes assignment: Katsuki is going to find his husband, grab the little shit, and kill him with kisses.
“I’m gonna kiss your fucking face off, give me my kiss!”
Katsuki can hear Deku’s laugh escalate at that, and the closer he gets to the kitchen, the louder it gets.
Katsuki grins. Making Deku laugh is almost as good as kissing him. Too bad Katsuki always gets what he wants, and what he wants right now is for Deku to give up and kiss him already.
Katsuki’s hands are popping as he skids down the hallway that leads to the entrance of the kitchen, the adrenaline of chasing his husband around their home surging through his veins. His socks aren’t as smooth as Deku’s, so he has more traction and doesn’t crash into as much shit as Deku did.
Heh, faster than the fucking nerd, even in socks.
With the way Deku is currently hunching over in front of the fridge, holding his sides, Katsuki doubts it would’ve taken much longer to catch up to him anyways.
“Deku,” he snarls, hands held out and ready by his sides. He pauses in the doorway of one of the kitchen’s exits, crouching and staring at Deku head on.
Deku isn’t even looking at him, trying to stand up and failing as his feet keep sliding and his body keeps shaking with glee.
“Yes, Kacchan?” he gasps, finally standing up and meeting Katsuki’s eyes as he turns around.
Katsuki had calmed down a little bit, having slowly closed in on Deku when he is still on the floor. He holds his hands and arms outstretched away from his torso, body crouching low so he can get eye level with Deku.
He’s hunting now, and his prey is in sight.
Katsuki can feel the feral grin slowly overtaking his face, canines glinting in the kitchen light and gums showing, a growing rumble building up in his chest. He narrows his eyes at Deku, calculating the space between them.
Deku blanches as soon as he takes in Katsuki’s stance, and Katsuki can see his body tensing up and freezing. He’s subconsciously taking his own battle pose in reaction to Katsuki, his knees bent, and arms slightly up in front of him. However, his quirk stays off, no radioactive glow flashing under his skin or in his eyes.
“Shit,” he mumbles under his breath, eyes darting from Katsuki’s feral expression to his open arms and twitching hands and back.
Finally, he’s taking this seriously. He thinks Katsuki is playing a game, with this back-and-forth they have going on. But Katsuki is deadly serious. He’s going to teach his husband a lesson.
Deku takes a step back. Katsuki takes a step forward.
Deku takes another back.
Katsuki takes another forward.
Deku inches back even more.
“Take one more step, and I’m going to murder your ass,” Katsuki says, his voice reverberating in his chest and echoing in the kitchen. He keeps slowly spreading his arms and hands out as he inches after Deku, sweat collecting on his palms as he keeps his quirk in check.
Deku is like a little bunny right now. Katsuki can’t make too big a move or sound and scare him off. He’s going to trap Deku and never let him go.
“Promise?” Deku smiles, taking an even bigger step out of the kitchen and into the living room.
Oh, that cheeky little shit. He’s going to get what’s coming for him. To hell with being cautious.
With a yell, Katsuki charges forwards, reaching for Deku and his fingertips brushing Deku’s shirt.
Deku yelps at the sudden lunge, eyes widening as he takes in Katsuki’s near miss.
Deku barely turns in time to run into the living room, eyes darting around quickly before landing on the rug under the couches and coffee table.
Katsuki knows what he’s trying to do. If Deku can get to the rug, the brief traction would give Deku a burst of speed and another head start.
But before Deku can make it to the rug, his socks finally betray him. He slips, and in the half second it takes for Deku to panic and try and save himself from breaking his nose on the hardwood floor, Katsuki pounces.
He grabs Deku around the middle, hugging his back to Katsuki’s chest and twisting them so Katsuki takes the full brunt of the fall as they crash into the back of the couch before landing on the floor. Katsuki took Deku to the rug, just not like how Deku had imagined it would happen.
“Ha! Got you! There’s no escaping me now Deku!” he yells, tightening his arms around Deku as he starts to squirm.
He turns so he’s lying on top of Deku, Deku’s chest to the floor and Katsuki’s arms banding tightly across Deku’s, giving him no way to push Katsuki away and run.
“No, Kacchan let me go!” Deku whines, trying to use his legs to kick Katsuki off him.
Katsuki grunts at the force, quickly moving to entangle his legs with Deku’s. Shit, Deku’s legs are the most dangerous part of his whole body, and if he gets one out, he has a chance at kicking Katsuki off him.
He loops his right thigh under Deku’s, trapping it from the outside and under it, then the top of his right foot over Deku’s calf, shifting them so they lay on their right sides against the floor, pressing Deku into the hold.
Deku starts giggling again, trying to gain momentum from his free left leg before Katsuki clamps it shut with his own, wrapping his other leg around it. Katsuki is unashamedly using his taller frame and longer legs to his advantage, covering Deku completely and hindering almost all his movement.
If Deku really wants to get out, he can, Katsuki knows this, but he really hopes Deku doesn’t. It’s his turn to tease Deku, give him a taste of his own medicine.
“You cheeky little shit, I’ll give you something to laugh about,” Katsuki says, right before he tightens his right arm around Deku so he can shift his other arm a little further down to Deku’s ribs.
That's when Deku really starts to panic, as he figures out Katsuki’s trajectory, and starts to buck in his arms, wriggling at the path Katsuki’s fingers are taking.
“Wait, Kacchan, wait, wait!” he yells, still struggling against Katsuki’s hold.
“Nah, it’s too late baby,” Katsuki says, smirking as he digs his fingers in.
Deku scream laughs, trying to jerk away from Katsuki’s tickling fingers.
Deku is the most ticklish motherfucker to ever exist, a fact Katsuki has known and kept close to his heart since they were children. Nowadays, everyone knows Deku is ticklish, and that he’s a somewhat easy target as Deku never expects it, but only Katsuki knows how to break Deku like this.
“No, Kacchan, oh my god, ha-ah! Stop!”
He barely manages to get out the words with how hard he’s laughing.
Katsuki only grins and digs harder. He shifts the hold he has on Deku, moving onto his back, and keeping Deku on top of him, giving him easier access and making sure Deku can’t escape while Katsuki tickles him.
“Please, Kacchan, I’m sorry, I’m-” Deku breaks himself off, laughing too hard to speak anymore. Tears trail down his face, laughing loudly and unashamedly as Katsuki continues mercilessly.
“Hah? Is that all you can say, Deku?”
Katsuki doesn’t let up, enjoying Deku’s suffering. Serves him right, trying to withhold Katsuki’s kisses from him.
Katsuki quickly moves his hands more in, hitting another spot on Deku’s upper ribs that makes him burst out with another uncontrollable laugh.
“Ka – Kacch - please, please I can’t breathe, Kacchan!”
Deku’s breaths are getting too fast and uneven from his laughter, so Katsuki reluctantly stops before Deku can pass out, moving his hand to join his other one around Deku and away from any ticklish spots.
He rubs his forehead down into Deku’s hair, smiling softly as Deku calms down. Deku thunks his head against Katsuki’s chest, his laughter trailing off into the occasional breathy giggle as he finally relaxes into Katsuki’s hold.
Got him.
Before Deku completely catches his breath, Katsuki reaches up, grips Deku’s jaw in his hand and yanks his face towards Katsuki. Deku lets out a startled sound, tensing up, his arm coming up around to hold onto Katsuki’s forearm for balance.
He strains to look back at Katsuki, his flushed face and wet eyes startled and nervous. His mouth is open with his harsh breathing, shiny and pink and so fucking enticing. The backwards tilt of his head onto Katsuki’s shoulder brings more blood to his face, turning pinker and pinker the longer Katsuki stares.
Katsuki doesn’t give him another moment to breathe.
He dives down, forcefully pressing his lips against Deku’s and stealing his breath. He tightens the hand he holds Deku’s jaw with, pressing further in, hungry, starving, waiting for Deku to meet him.
It only takes a few seconds for Deku’s brain to catch up, a gasping moan filling Katsuki’s mouth, his body relaxing back into his chest.
Perfect, Katsuki’s going to make sure Deku won’t even want to run away afterwards, is going to make sure he never withholds Katsuki’s kisses ever again.
Deku tastes good, like lightning and home and all the things Katsuki can’t go without. It’s burning, the heat radiating from Deku’s mouth and seeping into Katsuki’s, pooling in his gut. His cock twitches.
Deku starts squirming, hands grasping and clawing as he tries to get purchase on Katsuki’s arms, tries to anchor himself from the intensity that Katsuki attacks his mouth with. He can’t stay still, hips jerking every so often, legs twitching from where Katsuki still has them trapped between his own.
His eyes are lidded and dazed, the smallest sliver of green visible as he accepts Katsuki into his mouth. Spit starts to seep from the sides of his lips, escaping from where Katsuki locks his mouth onto Deku’s.
He shoves his tongue into Deku’s mouth, probing and prodding, licking and tasting every space and crevice he can. He can feel Deku’s hot tongue stroke his, content to be pillaged and ravished as Katsuki hungrily takes everything he can from Deku.
Katsuki wants more, he needs more.
He needs Deku.
Spit drips and clings between their lips as Katsuki leaves with a pull of Deku’s bottom lip between his teeth. His chest is heaving along with Deku’s, Deku’s weight pressing him down to the floor as he refuses to let go of him.
Deku is gasping, trembling, small tears squeezed to the corner of his eyes.
Katsuki is going to devour him.
“Damn, always playing games with me Deku, can’t resist playing with fire,” Katsuki speaks, low, dulcet tones worming their way into Deku’s ear and making him shiver on top of him.
“What’d you think was gonna happen, huh? Think I’d just let you get away, that you could escape me? Nah, baby. You brought this on yourself,” Katsuki continues, loosening his grip on Deku’s jaw to pet softly against his face and down his neck.
With the way Katsuki holds Deku’s head back against his shoulder, the pale expanse of his throat is on display, the barest hint of pink surfacing. Katsuki is going to turn it all purple.
“I think you wanted this. I think you knew exactly what was gonna happen, didn’t you?”
“Kacchan,” Deku whines, not answering. He starts to squirm more, hips twitching up with minimal success. Katsuki still has his arm banded around Deku’s arms and ribs, limiting his movement. Deku has no leverage to move, no friction or pleasure to gain from rutting up into the air.
“Kacchan, I just wanted – I just, Kacchan, please!” Deku struggles to turn, trying to meet Katsuki’s gaze again.
“What, baby, what do you want?”
Katsuki soothes Deku, still petting up and down the space between Deku’s jaw and neck with the backs of his fingers, occasionally reaching up to scratch into Deku’s hair. Each time, it earns Katsuki another delicious shiver, a barely audible moan leaving Deku’s mouth. It contrasts deeply with the slow, hard grind Katsuki starts, his need to destroy Deku’s ass fighting with his want to really destroy Deku, to take him apart, make him whine and gasp and tremble for Katsuki’s touch.
He ruts up into Deku, teasing Deku with a promise of what Katsuki plans to do, and is content (for now) with the shuddery whines he gets in return.
Katsuki kisses down Deku’s face, his soft, wet kisses leaving behind glistening patches of skin.
He mouths at Deku’s neck, working a patchwork of new bruises to ring around it in a facsimile of a collar.
He moves up to his jaw, nipping the jutting cut of it with his teeth then soothing it with his tongue.
He shifts to Deku’s freckled cheeks, biting and sucking and kissing until they’re even more flushed than before.
He kisses over his eyes and tastes his tears, kisses his sweaty temple, behind his ear, on top of his head, under his chin.
He kisses everywhere but Deku’s pouty lips, ignoring Deku’s attempts to turn and catch Katsuki in another kiss.
Not once does Katsuki’s mouth leave Deku’s skin.
He savors the taste, the soft feel of Deku underneath his tongue and lips, eating up all that he can of Deku.
Deku is trembling, twitching, chants of Kacchan, Kacchan, please and I want- I need it- you, I need you falling and tumbling out of Deku’s mouth with no space in between.
Katsuki moves down to Deku’s mouth, a breathy sigh escaping Deku as he anticipates Katsuki’s route. Katsuki moves at the last second, kissing right next to Deku’s lips, tonguing the corner, and relishing in the cry of frustration Deku lets out.
“Isn’t this what you wanted, Deku? Isn’t this what you did, denying me my kisses?” Katsuki murmurs against Deku’s plush cheeks. He shifts Deku up his chest as he moves down further, unable to resist biting into the muscles of his shoulders and tonguing the flushed skin of his neck, nudging the neckline of his shirt out of the way with his nose.
“I’m sorry, Kacchan, please, I-” Deku pushes out, never finishing his sentence, never clarifying what he’s pleading for.
Deku is still straining his neck towards Katsuki, eyes following Katsuki’s mouth and tongue to the best of his ability. Katsuki can feel the rapid beat of his heart under his arms, the rapid expansion of his chest pushing and pulling Katsuki even further into Deku’s orbit.
“I know, I know sweetheart, I got you,” Katsuki assures.
He tangles his hand into Deku’s hair, maintaining his grip and pulling Deku’s face closer to his own. Deku’s breath hitches, and he goes willingly, eagerly, pushing against Katsuki’s hold to go faster.
“That’s right, come here, baby,” Katsuki says, and he finally puts his lips back on Deku’s, bruising them with need.
Deku meets him equally, an arm squirming and escaping Katsuki’s hold to reach up and put his own hand in Katsuki’s hair, grasping and pulling Katsuki’s mouth harder into Deku’s.
They kiss rough and dirty, tongues sloppy with spit and lips raw with the force. Each time Katsuki pushes harder, pushes further into Deku’s mouth, Deku moans and opens more, pushes back against Katsuki.
He’s perfect, so receptive to Katsuki’s touch and tongue, eager for everything Katsuki is giving him. His cock throbs when Deku’s tongue strokes his, pulsing against Deku’s ass as he continues to grind up.
Deku tries to pull back the tiniest bit to gulp in lungfuls of air, and Katsuki takes the opportunity to stick his tongue back into his mouth, filthily licking his lips and his tongue. Deku is so focused on kissing him, low moans and breathy gasps escaping him every so often, that Katsuki is sure Deku isn’t even thinking about running now.
It gives Katsuki the chance to do something about Deku’s cock, so obviously tenting his gym shorts as Deku tries to seek friction against nothing but empty air.
He moves the arm he had kept wrapped around Deku’s ribs down, pushing straight into Deku’s shorts and brushing his weeping cock. Katsuki can feel the precome seeping into Deku’s underwear, sticky and warm.
Katsuki chuckles darkly, the sound muffled in Deku’s mouth. So wet, so ready.
Deku jerks when Katsuki’s fingers start to trail up and down Deku’s clothed cock before slipping under and grasping it with his whole hand. He doesn’t move his hand, simply holds the weight of it and lets Deku’s jerking hips do the work.
“Kacchan,” Deku moans, “don’t tease, please.”
His head is resting back in the crook of Katsuki’s neck now, hair brushing the floor, and both of his arms lift to join around Katsuki’s neck as he holds on as tightly as possible. Katsuki tilts his head down, kissing Deku’s bared neck and breathing in his heady scent. He smells like ozone and sweat, lust spilling out of him with every breath.
Katsuki moves his hand out of Deku’s hair, rucking Deku’s shirt up to find his nipples. A squeak rips out from Deku when Katsuki pinches one, playing with and squeezing it as Deku continues to thrust into his palm.
Katsuki’s palms are warm, easily radiating heat and slightly damp from his quirk. He’s careful to make sure he doesn’t hurt Deku, but he can’t resist raising the heat just a little, just enough to get that broken moan out of Deku he loves so much.
Katsuki finally properly grips Deku's cock and starts to quickly jerk his hand up and down. The only lubricant to ease the way is the precome spilling from Deku’s tip and the sweat of Katsuki’s palms. It’s just barely enough, the tiniest bit painful from the uneven slide and wetness of Katsuki’s hand, but it only makes Deku shudder even more.
Deku moans up and into the empty space above him, eyes closed tight against the rough pleasure he feels from Katsuki’s hand.
“Who’s teasing, baby? Do you want me to stop?”
He pretends to slow his hand down, chuckling when Deku’s eyes shoot wide open, jerking his head to meet Katsuki’s. Katsuki has no plans on stopping, can’t even think of the possibility when Deku is laid out so deliciously on top of him, his pleas and moans creating a beautiful symphony around them.
He’s so lovely like this, so overcome by pleasure that he secedes all trust and control of it to Katsuki. It makes Katsuki’s heart squeeze and his cock jump, the vulnerability in Deku baring his body so easily to Katsuki making him burn from the inside out.
“No!” Deku gasps, “Please, don’t stop!”
“But you don’t want to come yet, sweetheart, not when we’ve barely started.”
Katsuki doesn’t ask if he wants to come, he’s telling Deku he won’t. Katsuki wants to drag this out, to turn Deku into a shaking mess by the end of it.
“We haven’t even taken your clothes off yet, and you’re still so ready to come.”
He punctuates his words with a squeeze of his hand around Deku’s cock, Deku shouting and arching his back on top of Katsuki. Katsuki feels the hands in his hair grip a little harder, the sting making Katsuki hiss.
“So hard, so eager for me,” he taunts.
Katsuki plants his feet on the ground, knees up and in between Deku’s legs, forcefully spreading them apart. It gives him better access to Deku through his shorts and makes it easier to thrust up into Deku’s clothed back and ass. Deku’s legs lay twitching outside and around Katsuki’s, toes tensing on the floor as he curves up into Katsuki’s grip.
The rug and floor beneath Katsuki are starting to build up an ache in his back, the lack of support making his neck uncomfortable. Holding Deku’s entire bodyweight on top of him probably isn’t helping, but he has Deku right where he wants him, and he isn’t planning on moving anytime soon.
The clothes really are becoming an issue, though. Katsuki wants to feel Deku’s skin, wants to soak in the heat between them, to feel Deku’s writhing body and twitching muscles directly atop of his.
Goddamnit, he wants to fuck his nerd already.
“Deku,” he says, kissing his neck. “Take your clothes off. Be a good boy, yeah?”
“Huh?” Deku mumbles back, still thrusting up into Katsuki’s hands. So focused on the pleasure running through him, it takes him a second to register Katsuki’s words.
“Yeah, yeah, okay, Kacchan,” he says, slipping his arms away from Katsuki’s neck and moving to sit up on Katsuki’s torso.
Katsuki doesn’t let him go though, releasing Deku’s cock to move his arms around Deku’s hips and waist, roughly pulling him back down against him. The sudden pull brings Deku’s ass back against Katsuki’s cock, and he groans, unable to resist thrusting up against it a few times. Deku gasps at the sudden movement, pushing back against Katsuki’s cock.
“The fuck you think you’re doing, Deku?” he growls, tightening his arms when he hears Deku try to hide a moan.
“Kacchan, I need to get up to take my clothes off.”
Deku struggles a little for show, but the only thing he succeeds in doing is brushing his ass against Katsuki’s cock.
Katsuki sighs, the friction like fireworks in his veins. Katsuki really isn’t trying to bust a nut before Deku did, but goddamn is he making it fucking hard.
Still, Katsuki doesn’t let up. He keeps Deku’s back to his chest, shifting him up a little bit more so his squirms stop sending Katsuki to the next plane and his ass is resting more on Katsuki’s hips.
Deku melts into the motion, content to lay within Katsuki’s possessive grasp and be manhandled.
“Do it like this, don’t get up,” he demands, moving his hand to shove Deku’s shorts and underwear off him.
He doesn’t want any part of Deku away from him for too long. He doubts Deku will still try to continue their chase from earlier, his heaving chest and pink skin telling Katsuki all he needs to know, but he won’t take that chance, not now, not when he finally has Deku how he wants him.
He gets the shorts to mid-thigh, roughly pulling and pushing them down with one hand, but the newly exposed soft skin and clenching muscles in Deku’s legs distracts him before he can pull them off all the way.
Fuck but his thighs. Deku’s legs are a thing of beauty, heavily muscled with the occasional scar, soft freckled skin, thick.
Katsuki wants to wrap Deku’s legs around his head while he eats him out and suffocates in their hold. If Katsuki could pick a way to go, getting crushed by Deku’s legs would absolutely be his number one choice.
He lets go of Deku’s shorts to knead and squeeze his thighs, his hand caressing the inside of his thighs and garnering a shiver from Deku.
Finally, Deku complies, quickly kicking them the rest of the way off then toeing his socks onto the floor. Katsuki loosens his arm around Deku's waist to let Deku remove his shirt, moving his hands underneath Deku to help him rip it over his head.
Once Deku’s face is free, Katsuki immediately kisses him, hands frantically roaming up and down the expanse of his bare skin. Deku’s hot, his skin burning from every point of contact where he lays on top of Katsuki.
He feels so good, sounds fantastic, and Katsuki really can’t wait any longer.
He grabs Deku’s hips and flips them both over, rolling until Deku’s pushed against the floor with Katsuki’s full weight pressing him down. He turns Deku over underneath him so that they’re face to face, Deku’s heaving chest touching his with every breath.
Deku gasps at the sudden movement, hands scrambling over Katsuki’s arms and legs automatically moving around Katsuki’s waist. He stares wide-eyed up at Katsuki, mouth still open.
“Deku,” he growls. His hands squeeze sporadically over Deku’s hips, pushing and pressing into Deku’s skin until he’s sure bruises from his fingertips will be visible tomorrow.
Deku grinds up into Katsuki’s still covered cock, the rough fabric of his pants dragging against Deku’s dripping cock. Deku moans his name, closing his eyes and throwing his head back.
“Kacchan,” he breaths, still moving.
“Fuck,” Katsuki grunts, grinding back down into Deku, taking his arms, and pushing them into the floor. He slides his hands up and interlaces his fingers with Deku’s, thrusting down as he squeezes his hands.
“Gonna fuck you so good,” he licks into Deku’s mouth, “gonna take you apart, take your ass until you can’t think of anything but me.” He bites down on Deku’s lip, leaning back and stretching it until it slips out from between his teeth.
Deku moans, unintelligible words tangling up in his throat. He blinks up with wet eyes, and swallows, Adam’s apple bobbing and drawing Katsuki’s attention down.
“Gonna make it so you never take my kisses away from me again. You hear that, baby?”
Katsuki bites down on Deku’s neck harshly, kneading the tendons there as Deku cries out. He lets go with his teeth, kissing and sucking on the mark until it’s a nasty red quickly shifting to a deep purple. He wants all of Deku’s attention, wants all his thoughts on him, on the pleasure Katsuki’s giving him.
He leaves one last filthy kiss on his neck, laving his tongue and leaving the spot glistening with his saliva before leaning back up.
He moves up to Deku’s mouth, letting go of one of Deku’s hands to grip his jaw, pressing down and prying it open wider. Deku doesn’t resist, easily opening his mouth and relaxing his jaw under Katsuki’s pressure. His breathing picks up in anticipation, a shiver running through him as soon as he realizes what Katsuki is planning to do.
Katsuki can see Deku’s eyes dart down to his parted lips, tracing where Katsuki rolls his tongue around his mouth and opens it. Deku’s restless, sticking his own tongue out impatiently and wriggling under Katsuki’s body. His thighs sporadically squeeze Katsuki’s waist, betraying his eagerness.
Katsuki leans over Deku’s mouth, locks eyes with Deku’s teary ones, and spits.
The absolutely wrecked moan Deku releases makes Katsuki groan, hips twitching down into Deku’s. Deku’s cock jerks when he swallows, precum spilling and making a mess on Katsuki’s pants and Deku’s twitching stomach. Deku looks as wrecked as he sounds, trembling and panting with his mouth open, tears dripping down the sides of his face, all because of Katsuki.
Katsuki shivers, the delight of seeing Deku so debauched trickling down his spine.
He’s responsible for Deku being like this, he’s the reason why Deku’s cock is leaking against his stomach, why his hips can’t stay still and why his hand grips Katsuki’s with bone-creaking force. Katsuki can’t get enough.
Fuck, fuck, fuck, he needs to be inside of his husband.
He lets go of Deku’s jaw to shove his hand between their bodies, leaning back just enough for his fingers to tease in between Deku’s legs, moving down.
“Kacchan,” Deku moans, “please, touch me already.”
“Where, baby?” Katsuki cruelly keeps his fingers in one spot, pressing and gripping his soft inner thighs and away from Deku’s ass.
“Here?” he asks, moving his fingers down to push and massage against Deku’s wet hole.
Katsuki jerks back, seeing a new round of blush travel up Deku’s chest to his cheeks.
He’s wet…?
Oh.
Oh.
Katsuki chuckles, the sound rumbling in his chest, as he leans back and puts his fingers back against Deku’s hole, prodding and pushing the lube around.
So Deku was playing around today, was he? The mental image of Deku fingering himself, the moans and shuddering breaths with each finger going in as if to get ready for Katsuki’s cock makes him twitch, a half-aborted thrust briefly pushing him into the cradle of Deku’s legs.
Fuck, he loves his husband so much.
“Deku,” he starts, “just what exactly were you doing while I was at work?”
Deku groans, letting go of Katsuki’s hand so he can cover his face and shake his head. Despite his embarrassment, his hips make minute twitches into Katsuki’s exploring fingers, his hole fluttering with each touch.
He shakes his head again in denial, hands trembling where they cover his exquisitely flushed face.
Katsuki can’t have that, can’t have Deku’s big, beautiful eyes hidden away, not now. Deku wears all his emotions on his face, especially his eyes, and Katsuki will be damned if he can’t see it all.
Katsuki pushes a finger in, and immediately gets distracted as it goes in easy all the way, the soft shlick echoing filthily as a delighted grin lights up Katsuki’s face. He pushes a second finger in, just as easy as the first. Fuck.
“Oh, baby,” he groans, wasting no time in thrusting in a third finger and massaging the soft walls. “You really got yourself ready? For me?”
Deku moans, hands drifting down from his face to grip at Katsuki’s forearm. He doesn’t try to stop the movement of Katsuki’s hands, simply holding on and groping the moving muscles and tendons there as Katsuki fucks his ass with his fingers.
He looks up into Katsuki’s thrilled face, eyes hooded, and nods, lips pressed tightly together to stop any extra noise from escaping. Katsuki can still hear the muffled moans, despite his best effort, and they rattle his brain into nothing.
Katsuki slams the hand that Deku had let go of onto the floor next to Deku’s head, gasping out a good boy, so good getting ready for me before leaning down to devour open Deku’s lips with his own, taking all his sounds into his mouth, drinking them up and keeping them in his chest right next to his heart.
He doesn’t stop the motion of his hands, still twisting and caressing inside Deku’s hole.
He hardly has to do any work stretching him, but instead can take his time to tease and play with Deku’s prostate. Each time Deku makes a sound, each time he shivers or his cock jumps against his stomach, Katsuki can’t help but speed up his hand just a little bit, just enough to squeeze out another reaction from Deku.
Deku is burning, it’s so hot inside of him, the heat warming through Katsuki’s hand and blazing all the way through his body to his gut. Deku’s sucking, twitching, and pulsing around Katsuki's fingers, little gasps accompanying each thrust.
Deku starts to whine, head tilted back as far as it csn go and his body twitching, a light sheen of sweat making his skin glisten, all signs he’s about to come.
Well, Katsuki can’t deny he wants to see Deku come, to see his freckles overtaken by his blush, to see Deku lose control of his voice and limbs, to succumb fully to the pleasure Katsuki is wringing out of him. Except, Katsuki wants him to do it all on his cock, to press him down into the floor until he can’t move, until all he can do is hold on for the ride while he comes on Katsuki’s cock and nothing else.
Katsuki pull his fingers out from Deku’s ass, lingering for a quick second to thumb at the red rim, eyes glued to the way it pulses and twitches at his touch, before reaching down to undo his belt and the zipper of his pants.
He shoves them roughly out of the way to pull his cock out, not even bothering to push them or his underwear completely down. He strokes himself with the same hand that had been inside of Deku, spreading the warm excess lube around his cock and taking his other hand to ruck his shirt up and out of the way.
Deku’s legs fall from his waist when Katsuki leans fully back on his knees, naturally spreading his legs towards the floor as he keens at the sight of Katsuki’s cock. It’s achingly hard, the lack of proper relief until now turning it red, and the vein running up the underside of his shaft throbs in time with Katsuki’s battering pulse.
“Kacchan, Kacchan, I want it,” Deku mumbles, hands reaching out in a daze to Katsuki’s cock, not quite reaching all the way. He makes grabby motions with his hands, a pout starting to form when Katsuki only continues to stroke his cock and watch Deku with a smirk.
Cute.
“You’ve been doing so well, Deku, giving me my kisses, getting your ass all stretched and ready for me,” Katsuki murmurs, leaning down once again.
He removes the hand that had been holding his shirt up to grab one of Deku’s waving hands, pushing it back against the floor near Deku’s head and intertwining their fingers again. The praise makes Deku buck up against him, his cock briefly catching in the loose fabric of Katsuki’s shirt.
Katsuki kisses the pout, wiping it away with his tongue.
“You ready, baby?” he asks, knowing full well that the whines coming from Deku are because Katsuki is teasing him and not immediately shoving his cock inside him.
He sighs, nosing along Deku's cheek as he makes him wait a little longer. Really, the one time he tries to be nice to Deku by not immediately shoving his cock into him - and fucking hell, but Karsuki's been waiting to fuck Deku all day - and he doesn’t even appreciate it.
Deku lets out a groan, legs coming back up around Katsuki’s waist, his knees digging into Katsuki’s ribs and pulling him down, forcing Katsuki’s body to press Deku back into the floor.
"Now, Kacchan," Deku says, and tightens his legs further.
Katsuki’s flush against Deku now, the arm holding his cock trapped between their bodies as Deku wraps both his legs and his one free arm around Katsuki, mumbling and moaning directly into his ear about Katsuki’s cock, about how empty he feels, about how much he wants him, wants him right now, please, Kacchan, please, I need you inside, I can’t, Kacchan, please!
Fuck, Katsuki groans, he’s so fucking hot and he doesn’t even notice it.
“I got you, I got you baby, don’t worry.”
He guides the head of his cock to Deku’s hole, nudging and rubbing it against the rim, but not fully pushing in just yet. He wants to make Deku suffer just a little more, just enough to make up for him withholding his kisses earlier.
“Kacchan,” Deku groans. He squeezes Katsuki’s sides tighter with his legs, hand raking up his back and over his shirt to his hair. He grips tightly there, his other hand holding Katsuki’s with the same strength as he tries to thrust down onto Katsuki’s cock, tries to force him inside.
But with the way Katsuki has him pressed against the floor, his entire body bearing down on him, Deku has no leverage to push down, can only fidget and wriggle against the rug under his back, tears building up in his eyes as he pants from the effort.
Katsuki smirks, removing his hand from his cock to wrap underneath Deku’s neck, caging him in his arm and forcing his head into the crook of Katsuki’s neck. He threads that hand into the side of Deku’s head, gripping the hair and tugging Deku to make him stay still.
He leans down, licks Deku’s lips, then slams his cock into Deku’s ass with no warning.
And, fuck, but he's hot, the blazing heat of Deku’s insides making him grunt in tandem with Deku’s short scream. He’s so tight, Katsuki’s a little afraid Deku’s going to rip his dick off.
He pulls back quickly, slamming back in and forcing another scream that tapers into a moan from Deku. Deku's knees and hands are gripping him so tightly, tight enough to bruise, as if he's afraid Katsuki will pull out and leave him.
There’s no way in hell Katsuki is leaving right now, not with the way Deku sounds and feels.
He pulls back out and pushes back in with the same fast paced rhythm, forcing Deku’s body to scoot up the rug centimeter by centimeter from the force of his thrusts.
There’s a moment where Katsuki worries the rug will burn Deku’s back, but Deku doesn’t even seem to notice. If anything, his babbling gets faster, less coherent, and he clutches harder to Katsuki, keeps asking him to go faster, to go harder.
And who is Katsuki to deny his husband?
He can tell he’s making it hard for Deku to breath, the weight of his body limiting the expansion of Deku’s chest, each push of Katsuki’s cock into Deku’s hole punching little gasps of air out of him, the arm he has around the back of Deku’s neck and cradling his head restricting Deku’s ability to move away and gasp for fresh air.
It all works to make Deku the perfect masterpiece, his husband a breathless, flushed mess, the only thoughts in his head being Katsuki’s body and the feel of his cock paving a way through his insides.
Katsuki groans as Deku squeezes down on him particularly hard, a trembling moan escaping Deku’s lips. Katsuki moves faster, bracing down on Deku’s body and squeezing his hand to give him leverage. He keeps his lips on Deku’s face, on his neck, on his skin, sloppily tracing his freckles and leaving large purple marks anywhere he can see.
“You feel so good, baby, you’re so hot and tight, like a goddamn glove. You take my cock so well, made just for this, just for me, weren’t you?” Katsuki pushes out, each word punctuated with his cock.
Deku moans, a high-pitched sound echoing around them to match the slick sounds of Katsuki’s cock thrusting in and out of Deku’s ass, one that Katsuki takes as agreement. The praise forces more precum out of Deku’s cock and onto his already glistening stomach.
Gorgeous, Deku is gorgeous, laid out and taking his cock like this. He’s eagerly trying to thrust into Katsuki’s cock with every pull and push, despite how little he can actually move under Katsuki.
“You like this, Deku? You like taking my cock? I know you do, so eager for me to fuck you, you couldn’t even wait for me to get home that you started all by yourself.”
Deku only gets louder, and Katsuki licks the tears on his face, sucking on his cheeks and kissing the corner of his eyes. Katsuki leaves his face a bigger mess than before, shining from the path Katsuki’s tongue takes when tasting Deku.
“It’s okay Deku, you’re close, aren’t you? I can feel your cock twitching, your hole sucking me in, fuck," Katsuki grunts, biting down on the junction between Deku’s shoulder and neck again. Deku can hardly speak now, let alone say Katsuki’s name.
“Ka- ah, ah, ah, Kacch-ah, ah,” he gets out, his sweet voice rough and gritty from his moans and cries. It’s music to Katsuki’s ears, the melodic tone paired with the fucked-out gruffness making Katsuki moan into Deku’s shoulder, picking up his pace until he’s slamming into Deku so hard the sound of their hips meeting echoes along with their cries.
“Kacchan, I’m gonna, I’m-!” Deku yells out, just barely making his words clear enough for Katsuki to understand.
Katsuki grunts, shifting the angle of his thrusts but not letting up with the force or the speed. He’s using the arm he has around Deku’s head to pull him down into each push of Katsuki’s cock, his other hand squeezing Deku’s hand in his and forcing it against the floor.
Katsuki's searching, aiming for the spot he knows will make Deku lose it. He’s almost got it, can tell by the random twitching of Deku’s feet against his back, the occasional high-pitched shriek that seems to be punched out of Deku’s throat. His back is starting to ache with the speed he’s working to maintain, but Katsuki has it, he knows Deku’s body like the back of his hand.
Fucking, right there.
Deku screams as soon as Katsuki’s cock hits his prostate dead on, his ass squeezing around Katsuki so hard it feels like if he tries to move, he simply won’t be able to, prisoner to Deku’s ass.
Hell, if that doesn't sound like heaven.
Katsuki keeps his angle, pulls back the little bit he can, and hits it again, forcing another yell from Deku, his moans intermingled with his cries at the almost painful stimulation. Katsuki’s battering his prostate with every thrust, and between one moment and the next Deku seizes up.
His eyes go wide, tears falling smoothly as he looks unseeing into the ceiling above him, back bowing underneath Katsuki as much as he can. His cock spurts as he comes untouched, his legs twitching uncontrollably against Katsuki’s ribs and forcing the air out of him. His hands squeeze Katsuki, the force bruising against his hand and his back.
Deku screams, the sound tapering off into a silent moan as his body is wracked in shivers.
Fuck, fuck, fuck.
Katsuki keeps slamming into Deku, keeps up the same pace and the same angle as he chases his own orgasm. He’s so tight, and Katsuki’s pace stutters despite his best effort. He’s gasping into Deku’s ear, groaning with each thrust and each twitch of Deku’s ass.
Deku’s whining now, little hiccups escaping him as the overstimulation makes him dizzy with the pain-pleasure.
He holds on as best he can to Katsuki, but Katsuki’s fucking like a wild animal now, letting go of Deku’s hand to wrap it under Deku’s waist, lifting his hips so he can fuck into him unhindered. He’s frantic, chasing that burning, twisting pleasure he’s only ever felt with his Deku, with Izuku.
Deku calls his name, wrapping his arms around his head, forcing Katsuki’s face into his neck.
“Kacchan, I love you; I love you, I love you, I love you,” he repeats, over and over again, in time with Katsuki’s thrusts. He’s babbling now, eyes rolling back and body jerking with each push Katsuki makes. His cock twitches desperately against his stomach, hardening despite having come just moments ago.
“Kacchan, come, please come inside, I want it, I need it, I need you, I love you, I love you, Katsuki,” he says, he keeps talking, Deku keeps running his mouth and he just won’t shut up.
“Kaccha – ah – Kacchan, please, hng, please,” he pushes out, words slurring, and that’s it for Katsuki.
The blazing heat in Katsuki’s gut bursts at Deku’s words, driving his hips into Deku’s with a last few aborted thrust as Katsuki comes inside Deku.
“Izuku,” he gasps, gripping, digging his fingers into him and pulling Deku against him as tightly as he can as his cock jerks inside of Izuku, letting out stream after stream of cum and making Deku moan from the heat.
Katsuki continues to roll his hips, drawing out the feeling until it’s just shy of too much, slowing to a stop and huffing against Deku, breathing in his scent as Deku soothes his hands down Katsuki’s sweaty neck and over his shirt. His hand reaches under to stroke over Katsuki’s lower back, the skin damp with sweat and burning.
Fuck, it’s hot, he should’ve taken his goddamn clothes off. He regrets not being able to feel all of Deku against him, not feeling the brush of his nipples against his chest or see the mark of his ring pressed into his skin.
They lay there and come down, listening to the other’s pulse as they breathe together. Deku doesn’t ask Katsuki to get off him, though he’s sure by this point he must be getting too heavy.
With one last heaving sigh, Katsuki moves his arms so he can push up onto his elbows, hovering over Deku so he can look at his face. His cock is still inside Deku, though he can feel the lube and come slowly start to drip out the sides, Deku’s hole relaxing.
Deku is still randomly twitching, his lids heavy and eyes dazed. As soon as he sees Katsuki looking at him, a dopey smile shows up on his face.
Katsuki snorts aloud, absently moving his hand to play with Deku’s hair. Guess he fucked Deku’s brains out.
“Kacchan,” Deku says, still staring up at Katsuki, the leftover tears in his eyes sparkling like little gems.
“Yeah, Deku?” he says fondly, twirling and combing his fingers through Deku’s sweaty hair. Deku’s pushing up into his hand, melting into the motions like a cat.
Katsuki should start a bath soon, rinse them both off.
“Kacchan,” he hears, this time with a giggle. Deku’s eyes don’t leave his face once, staring unabashedly up at Katsuki.
“Deku,” Katsuki says back.
Deku hums, another Kacchan softly coming out. Deku’s saying his name just to say it now, all love and affection emanating in his scratchy voice.
“You did good, baby,” Katsuki says, leaning back onto his knees so he can stroke his hands softly over Deku’s sides, soothing the leftover twitches. He pets up and down Deku’s chest, fingers trailing and counting each rib. He massages the muscles, thumbs briefly brushing over Deku’s nipples and making him shiver.
Deku’s neck is one big, mottled bruise, Katsuki’s countless bites and kisses marking every inch there. He’s covered in a light sheen of sweat, cum drying on his stomach and chest. He has tear tracks on his face, and Katsuki’s spit and kisses on his cheeks. His lips are puffy and red, tongue visible as he breaths heavily.
This, this right here is exactly what Katsuki wanted to see.
“So pretty,” he mumbles, eyes riveted to the way Deku’s body shakes the tiniest bit at his touch. His cock slips out, a rush of cum following it, and Deku lets out a breathy sigh. Katsuki’s going to have to deep clean the rug now, but it’s worth it, for the way Deku sounds.
“Mm, Kacchan,” he says, making grabby hands at Katsuki yet again, arms wide open for a hug.
“What, you want a hug?” Katsuki asks, feeling and rubbing Deku’s soft skin still. He massages the bruises in Deku’s hips, ten little spots, front to back, where Katsuki’s fingers pressed too hard catching Katsuki’s attention like beacons.
Deku simply opens and closes his hands, the tiniest of frowns forming on his face and dipping his brows.
Katsuki huffs, but leans down anyways, wrapping his arm under Deku’s waist, the other under his head again. He feels Deku’s thighs come back up as he presses soft kisses to Deku’s neck, softly mouthing his way up his jaw and cheek to the corners of his mouth. He’s pressed flush against Deku again, sharing his heat and his breaths, living in his embrace.
“Love you,” he presses into Deku’s skin, each kiss marked with those words. Deku clings tighter to him, answering with his own love each time.
He leans back a little, staring down into Deku’s face.
“Gimme a kiss,” Katsuki says, voice so low it’s almost a whisper.
“’Kay,” Deku whispers back, dopey smile still lifting his cheeks and shuttering his eyes.
And this time, when Katsuki moves down to kiss Deku’s lips, Deku doesn’t move away.
