Nobody ever told Katsuki that bottoming fucking sucks. It can eat his whole fucking ass as far as he's concerned.
To be fair, he's never asked anyone—and why fucking would he? That shit is personal and, perhaps more importantly, he never thought he'd find himself in this situation.
Actually, he isn't quite sure how he found himself here in the first place. Some of the details of his and Deku's first time are branded on his brain, struck with a hot poker of scorching touches and smoldering looks. Other moments are like a heat mirage—wavering before his eyes as they left him breathless and lightheaded and more than a little dehydrated.
Deku said something like: "Do you want me to…I can take you if you want?"
And what's that supposed to mean anyway? Take you as in take you inside or take you as in take your anal virginity?
Of course, anything happening that night was heading in the direction of taking any and all virginity that Katsuki had, but he did a good job of not saying that out loud, even though Deku knew, and he knew that he knew.
Deku picked up on the fact that what he said was not fucking helpful and started blabbering again, "I mean, I don't know, but if it would be easier, I can be on the bottom…"
If it would be easier?
Then Katsuki said something like, "Fuck you, nerd, I can take your stupid dick."
Katsuki supposes that's how he got himself in this situation.
And he knew about anal, okay? He heard that it would feel like taking a shit, and it sure fucking did. But knowing that beforehand meant that he could almost separate it in his head. Just knowing that he wasn't taking a massive fucking dump on Deku's dick was enough to convince himself that shit wasn't all that it felt like.
He did come after all.
How could he not? He talked himself into the penetration itself being neutral at best, but everything else had been embarrassingly good. Deku kissed up his neck, panted in his ear. He was the one reducing Japan's fucking golden boy to nothing but little breathy squeaks that were heating up that whole side of his body.
The heat spread from the humid breath on his ear to the line of sweat gluing the sides of their bellies together to the hand Deku had slipped between them, jerking Katsuki off with every thrust. It spread across his face so that his cheeks nearly steamed, for once mirroring the blush that bled down Deku's face until it pooled into the bites and hickeys Katsuki left on his neck.
It was hot everywhere so that all the sensations bloomed into one another. The kiss on his neck worked with the hand on his cock which worked with the weird fucking sensation of Deku driving in and out of his ass. The moment Deku spilled inside him was the moment the heat became unbearable, like he was dying in one of his own explosions, scorched from the inside out. And then he came himself, squeezing so hard around Deku that he'd never forget the strangled sound Deku made. Something between a sob and a shout that got stuck in his throat the moment he'd collapsed fully onto Katsuki's chest.
So yeah, sex is fine. Pretty good, even, though there's no need to stroke the nerd's ego with that knowledge.
But anal? Anal can get fucked.
Oral is so much better. A simpler ordeal, oral is. No need for prep, no goddamn enemas, no accoutrements needed. Just a mouth and a dick and a willingness to get the job done. Which Katsuki has in spades as the head of Deku's cock drags against the roof of his mouth, Katsuki's tongue laving over the veiny underside.
The two of them fell into bed after dinner at Deku's house—Katsuki's ingredients, because Deku can never keep his fridge stocked with much besides eggs and condiments. Their first time was a few weeks ago now, but since then they've made do with blow jobs and hand stuff.
It's mostly work's fault. They've hardly had time for dates and, if they do, they often just have a meal and then fall asleep. It's a lucky night when that manages to happen in bed instead of on the couch.
But on a night like this, avoiding going all the way is all Katsuki's doing. It isn't like Deku's going to protest when Katsuki's mouth is around his cock anyway.
Katsuki is on his belly, licking the shaft from base to head before leaning down and wrapping his lips around one of Deku's balls. He's still studying what brings out the biggest responses from Deku, and a little ball play causes him to groan and grab Katsuki's hair, the filthy fuck.
"That's so good, Kacchan," Deku says from above, his back against the headboard as he whispers like Katsuki is sucking the voice right out of him.
Katsuki hums, the best iteration of "I know" he can orate as he sucks the ball against the flat of his tongue, then noses the base of Deku's cock as he moves over to the other one. Here, he can lick and suck and mouth away at Deku until the other man's taste vanishes. Until Deku's balls and the thick base of his cock taste like nothing but spit—then Katsuki can tongue back up and taste that salty pre-spend on his lips. He does just that and sucks Deku down just past halfway—the best he can do at the moment without testing his gag reflex.
"So, so good, Kacchan," Deku croons as he brushes his fingers through Katsuki's hair, curving over the crown of his head and planting his broad palm, torn and stitched, under Katsuki's ear. His knuckles bend, capturing white-gold spikes of hair between them.
Deku's getting chattier too. The first time Katsuki touched his dick, only the thinnest of sounds came out. Katsuki would've been sure the guy had forgotten how to breathe entirely were it not for the occasional wheeze that made it out between all the choked groans and whines. The first time they had sex, he wasn't sure Deku managed a single word more articulate than "Ka-ngh," the whole time.
Now, as Katsuki proceeds to bob his head, Deku's running both hands through Katsuki's hair, practically petting him while saying, "You're so good at this, Kacchan. Every time, you're so good for me. I love you so much, baby—please keep going."
Katsuki squints up at Deku, about to have something to say about petting him like a dog, when he sees Deku's head tap against his headboard, his eyes closed and scrunched almost in concentration. In their field, concentration always comes with eyes open, tracking for any threats or new considerations. But here Deku is, all his training and honed reflexes leaving him because of a lousy blowjob.
Katsuki keeps going.
All the bobbing is stiffening his jaw, making it ache and cramp, but that isn't enough to stop. His impulse is to let his teeth lightly tease the shaft, but that hasn't gotten the best response in the past, so instead, he tries to shift his tongue into the pocket of his right cheek, licking a stripe up the side as he pulls back up.
Deku groans, giving Katsuki's hair a slight tug in the direction he's going as he whimpers, "Yes, you're so good for me, Kacchan. The absolute best for me."
Maybe it's the lack of oxygen, but Katsuki's cheeks begin to heat up. He pulls off and gasps for breath, wrapping a hot hand around Deku and jerking him off as he looks up again.
Deku's eyes are open now, blinking down at Katsuki. "You're doing so well, Kacchan," he murmurs. "Can you keep going?"
Katsuki prickles. Of course he can keep going.
He promptly swallows Deku back down, pulling a whine from the other man. He pushes himself down further than he did last time, his eyes welling up at the intrusion. But he isn't gagging, so he holds Deku's cock there and sucks just once before pulling back.
"Fuck," Deku groans, running his hands down over to top of Katsuki's back before finding his hair again. "You're so good at this, Kacchan, and you look so, so good."
Deku uses both hands to push Katsuki's bangs out of his face, leaving him more revealed with his mouth full of cock than Katsuki maybe would like, but he isn't about to stop now. Not when the green of Deku's eyes is being eaten away by the black, looking like a man possessed just because his dick's getting sucked by, let's face it, a relative amateur. One of Deku's hands stays in Katsuki's hair while the other comes to his cheek, cold as clay against Katsuki's burning face.
"So pretty."
He should hate it.
"So, so pretty, Kacchan."
He should take the drool saturated with precum pooling in his mouth and spit it in Deku's lap at best. But he doesn't.
"So pretty, Kacchan, I just wanna see you."
He moans.
Katsuki leans into the hand on his cheek and closes his eyes as he lets his mouth drop down again, wanting to pull more sounds from Deku.
He's successful, earning a little gasp as Deku's cock hits the back of his throat. His lips are just about two inches off the base, but Katsuki can't go any further. He holds himself down as long as he can, though, suctioning all the air off in his mouth and blinking through the sharp stinging at the corners of his eyes.
The hand that was on Katsuki's cheek slides down the back of his neck and beneath the collar of his t-shirt and lightly scraped his nails up to the base of Katsuki's neck. Neither of them made much of a show of getting undressed tonight, save for Deku's pants kicked to the end of the bed. Both of them still have their shirts on and Katsuki is trapped in a pair of dark jeans that are starting to feel uncomfortable down where his hips are pressed into the bed.
"Yes, yes, yes, so good, for me Kacchan, so good—again, again, please."
Katsuki obliges, rising off Deku's cock and feeling some cold air on his face before plunging himself right back down, his thoughts becoming quiet as he focuses in on the goal of getting Deku off. Of being good for Deku.
He sucks as hard as he can, the pressure of his cheeks pressing in against his lower molars adding to the ache in his jaw as drool escapes out his lower lip. The mangled whine that comes out of Deku's throat is like music, a warble just for Katsuki's ears as he releases the suction, teases the tip of his tongue on the shaft as much as he can from that depth, and then sucks again. As he does, he presses his waist down into the bed, the pressure against his jeans pulling at his brain, telling his hips to move.
"So beautiful, baby, can I see your eyes? Can I please see your eyes?"
Katsuki looks up, tears streaming twin trails down his cheeks. They start out so hot but quickly fall cold as they roll over the heat radiating from his cheekbones and then hook behind the juts of his jawline.
"Kacchan," Deku whispers, his voice reverent. He takes both palms and presses just the heels lightly against Katsuki's cheeks, wiping away the tears until all ten of Deku's fingers are wrapped in his hairline, pushing sweaty locks of hair away from his face. "So gorgeous, I can't believe I get to look at you like this."
Katsuki's whole body is hot now, damp in spots from the drool on his chin to the sticky mark growing on the front of his boxers. He grinds down into the bed again, looking for a spot of relief, but finding that every movement just sends more fire through his body. His throat burns from the groans and gurgles he manages whenever he hears something he really likes, something that brings an extra flush to his face.
When Katsuki sinks down again, one of Deku's hands rotates so that the thumb is pressing into the hollow of Katsuki's cheek, pushing onto his own dick. Katsuki bobs quickly up and down so that Deku can feel that drag, feel how good Katsuki is being as he continues to thrust blindly against the mattress.
Every move of Deku's hands comes with more sweet words, how pink Katsuki's lips are, how prettily his eyes shine, how good Katuski feels on his cock. Every word zings right through Katsuki, emptying his brain of all other thought and making his chest puff with pride. Deku tells Katsuki that he's the best, and Katsuki knows he's the best. Deku insists that there's no one better, Katsuki knows that he's the only one who can do this to Deku.
As his head becomes light, lost in the rhythmic bounces of his neck, eyes rolling back whenever Deku strokes his hair, everything else goes quiet. His ears are ringing so that Deku's constant stream of praise feels like boiling water in him, dancing with bubbles and steaming out his ears.
"I love you, Kacchan, I love you so much, please, Kacchan, I'm almost there, you're so perfect for me, I—"
Katsuki latches onto the tip of Deku's cock and sucks just as hot streams of release shoot into his mouth. Deku's babbling doesn't stop, his eyes closed as he scratches hot stripes under Katsuki's t-shirt, making Katsuki whine as he mindlessly swallows the last of Deku's spend.
When he pulls off, he's panting, each breath bringing cold relief to his singed throat. His mouth still hangs open and he stays in Deku's lap, looking up at the other man with bleary but wide eyes, blinking, waiting.
Deku's face relaxes with the relief of an orgasm come and gone. A lazy smile rises on his face and he pets his hand over Katsuki's ear one last time, like he's brushing a lock of hair behind it.
"That was so good, Kacchan, thank you so much," he breathes, his lips loose and lazy as the words tumble out. "You were so good for me, was that okay?"
Katsuki's coming down from the high himself, feeling that hot rush of blood that had been living in his cheeks slowly recede, the cold air of the room licking it away with every pounding heartbeat. The ringing in his ears becomes nothing more than echoes of pretty and perfect.
He's heavy and slow-moving, like the crystallized syrup at the bottom of the jug as Deku's hand tenderly touches under his chin, thumbing away the drool that slid there. The slight lift of his head is enough to push Katsuki higher on his forearms, his hands gripping the meat of Deku's thighs. He blinks slowly and sees the wrinkle over Deku's eyes, folding away a couple of his freckles. Katsuki frowns. That's not the face of someone he was just perfect for.
"Was that okay, Kacchan?"
"Yeah, s'was fine," Katsuki slurs, smiling sleepily, half wishing to use Deku's tree trunk of a thigh as a pillow and fall asleep right there.
"Okay, well, do you want me to take care of you?" Deku asks, recovering from his orgasm quicker than Katsuki is from giving it to him. He hooks his hands under Katsuki's arms and helps pull him to his knees so that he's kneeling between Deku's outstretched legs.
Katsuki takes a second to follow the question, and in that time, Deku has already looked for and found his answer. A hot hand is pressed in the crease of Katsuki's thigh and Deku's frowning in confusion while Katsuki feels a cooling wetness sticking against his soft dick. In the back of his mind, he thinks oh, I came. There isn't anything in the front of his mind beyond the fact that Deku has bitten his bottom lip red while his upper one was nearly colorless but for the freckles that make it even there.
But then his eyes are drawn up. Deku's eyes are wide, halfway crossed as they try to take in both of Katsuki's at the same time.
"Oh," he says, his voice inflated with the twin breaths of awe and surprise. "Oh, that was…damn."
Katsuki nods, his head falling easily into residual, mindless bobs. Then Deku's drawing himself up, both their knees wobbling on the jostling mattress, and he catches Katsuki's cheeks in his hands one last time. And Katsuki, for one, is all for it as he leans in and finally catches that bitten bottom lip between his teeth and bites it himself.
Deku thinks he knows something now.
The fucker waltzes around the house—his or Katsuki's—thinking he can get away with being late or leaving a mess or having hurt himself on the job by saying, "You're so good to me, Kacchan, what did I ever do to deserve you?" and leaning in for a kiss.
Katsuki puts a stop to that by clonking their foreheads together instead. But Deku, the quick bastard that he is, works around that by changing tactics and pulling Katsuki in for a hug, leaving Katsuki with fewer violent options outside of resorting to his quirk.
Good thing the asshole never does it while they're on duty or Katsuki would explode Deku's face, just to make sure that his is the redder one.
Because that's the thing.
Whatever this is, this…thing that happened, Katsuki can't pretend it didn't happen. Can't pretend that he hadn't come in his pants with nothing more than Deku cooing his name, touching his hair, and some teenage gyrating against the mattress. Can't pretend that the flush that rises to his face every time Deku whispers a word of praise in his ear is nothing more than embarrassment. It's heat. It's want.
And when Deku stops doing it, Katsuki misses it.
A week and then two go by without the complimentary teasing—although, not really teasing; the jerkoff is genuine and Katsuki knows it. The compliments that Deku gives him are normal ones about how good his cooking is or how successful a rescue he's pulled off. They still make Katsuki's heartbeat subdivide in time, but they're passing comments. They aren't the same.
Their next date, one that doesn't end with them asleep on the couch, dirty dishes on the coffee table, doesn't come quickly. This time, they are indeed on the couch, but Deku has Katsuki pushed flat on his back, and they're trading kisses that are increasing in heat for the first time in over two weeks. Deku initiated, as he usually does, and Katsuki simply went along with it, as he usually does. He's only in this position—on his back, Deku pressed between his legs, just beginning to grind their crotches together—because Deku is so damn pushy. That's it.
At some point, Deku starts mouthing against Katsuki's earlobe, kissing it like it can kiss back. It sounds stupid, should be stupid, but it feels good and Katsuki finds himself with his head turned to make the angle better for Deku, breathing moist air into his couch cushion.
Deku catches Katsuki's earlobe between his teeth and nibbles it while Katsuki grabs at Deku's ass, pushing their hips even closer together. Coming in his pants is no fun, but it doesn't hurt to get most of the way there. Well, actually, sometimes it kind of hurts, but it sure doesn't yet and Katsuki is eager for more. But before he can start moving things along, Deku breathes in against his ear, murmuring, "Kacchan."
"What?" Katsuki asks, turning his head back out of the couch and leaning in to mouth above Deku's collarbone.
Deku shifts, following Katsuki's ear as he whispers, "I want to make love to you again."
Katsuki freezes, breathing openmouthed onto Deku's collarbone, nose pressed against his neck. He bites down.
He said no.
For the night. Of course he did. Maybe somewhere along the way, he won't care so much about having advanced warning for these things, but as it is right now, he has an enema douche and he bought it for a reason.
So they planned for another night. And Katsuki has spent the requisite time with a towel on his belly on the bathroom floor—thank God he lives alone—and taken care of his end of things for that evening. Now he's back in the hallway before Deku's apartment where they—Katsuki—have decided to eat after…after.
Which means just getting straight into it, he supposes.
Katsuki isn't sure how that's supposed to go. Even their first kiss was fueled by heat and impatience and altogether too much pining. Most of their subsequent intimacy has occurred organically through making out on the couch during a boring movie or being keyed up after a good fight—against villains or each other.
The idea of having sex because it's scheduled was his idea—by necessity—but how is he supposed to want it just by stepping through the door?
He knocks. The door swings open immediately, as though Deku was standing by it the whole time. Although, it's equally possible that he used one of his many quirks to sprint through the house, landing him in front of Katsuki.
"Hi," Deku says, his voice soft as the mood lighting he has going in the living room. "You look handsome."
"Hi."
Katsuki turns away, making eye contact with his shoes as he takes them off. He doesn't look particularly handsome today. He spent so long prettying up his asshole that he didn't put any extra care into his hair or anything. The only thing he can say is that he's wearing a badass bomber jacket and belted jeans—which are probably the dumbest thing that he could have worn for a date like this. But wearing sweatpants feels like advertising: here's my ass, ripe for the taking.
He pushes his jacket into Deku's chest, the deep brown of its fabric making it one of precious few neutrals to make its way into Deku's apartment. People gift Deku nothing but All Might themed goods and they're certainly all that Deku buys on his own.
The jacket goes in Deku's closet and then the two of them are left with nothing but expectation between them. Deku cocks his head to the side and smiles slow and open. Like it takes time to set aside all walls and make his face as warm and accepting as Katsuki has ever seen it. "Hi."
"You said that already."
Deku is unbothered. He takes one of Katsuki's hands in his and intertwines their fingers. Katsuki lets it happen, but perhaps his grip gets a bit tighter when Deku squeezes his hand. "I'm glad you're here."
This is how it happens. Looking at the nerd and wanting him. Being willing to try this, even though Katsuki is halfway sure that it'll still mostly feel like actual shit. The only reason that it might not is because of the guy looking back at him.
"Um, I know that we said that we would eat af—er, later—but if you've changed your mind we can eat now? Really, we can do anything that you want, I don't want you to think—"
"Deku." Katsuki grabs Deku's chin in his hand, thumb and fingers pressing into either cheek so that his mouth is jutting out and mercifully quiet. "Bedroom."
"O-Oh, okay!" Deku agrees, his words coming out smushed, as Katsuki has a tight grip and it hasn't gone anywhere.
Deku leads Katsuki to the bedroom, their hands clasping tight the entire time. The bedroom is much like the rest of the house: All Might figures on the dresser, posters on the wall, framed now, which is an upgrade from high school, Katsuki supposes. The linens on the bed are navy blue and just under one of the pillows, Katsuki sees what he can only assume to be an All Might towel sticking out.
Katsuki isn't sure why he didn't just invite Deku to his house.
After a moment of staring at the towel, Katsuki looks to Deku, eyebrow raised. He doesn't say a word.
Deku can't stand silence, though, and releases Katsuki's hand, scurrying to the head of the bed and pulling out the towel and a bottle of lube, putting them on a bedside table instead. "I didn't wanna be presumptuous!" he exclaims, face already beginning to flush.
"Pft," Katsuki scoffs. "That was kind of the whole point, doofus."
"So, you still…?"
Katsuki raises his hands, palms up, just a couple inches away from his thighs and says, "I still."
Each of Deku's muscles relaxes, softening him from Hero Deku to nothing more profound than Katsuki's boyfriend. He walks over and they wrap their arms low on each other's waists, eyes just a couple inches off from being level with each other. Then, before Katsuki's even thinking about it, they're kissing, lips soft on one another to start.
The nerves are there, sizzling below the surface, more so than even during their first time. Back then, Katsuki didn't know what to expect then past what he'd read and heard. But now he does, and, deep down, he really wants it to go well. Everyone says it's normal for first times to be bad—and his wasn't even bad it just wasn't stellar—but that it gets better.
Katsuki wants that.
Their soft kisses progress into fully making out, hands exploring over their broad bodies. Deku's are sliding into the back pockets of Katsuki's jeans to pull him close and Katsuki's are slipping under Deku's shirt. Deku's abs tense as soon as Katsuki touches them, hard as eight rounded scales under Katsuki's fingertips. The next breath relaxes them again and Katsuki can scratch straight lines under his ribs.
Deku has backed Katsuki up against the bed so that the low mattress is hitting behind his knees, but he won't go yet. Not when he's just gotten his hands on Deku, not when only his first layer of doubts has been sloughed away.
"Kacchan," Deku pants, kissing Katsuki again before pulling back. Like it's asking too much to stop even for a moment. "I wanna…try kind of what we did that time."
Katsuki doesn't want to keep his mouth to himself either, teasing Deku's ear in the way he had on the couch a couple weeks back. "What fucking time? Be specific, Deku."
"When…" Deku sighs as Katsuki licks a fat stripe from the side of his neck back to his ear and catches the lobe in his teeth. His voice sounds like a light breeze whistling through a crack in the window. "When you sucked me off? And you…you seemed to like the things that I said."
"Dunno what you're talking about, nerd," Katsuki says. "Thought you wanted something more than another fucking blowjob."
Katsuki hides his face further in Deku's neck—nothing should be visible but his hair out of the corner of Deku's eye. His face is already flushing and he doesn't need it to give him away. He takes the opportunity to flip the front of Deku's shirt over his head, blocking out his face for just a second as he quickly bends down to bite Deku's nipple.
"N-No, not that," Deku says, his voice stuttering as he fumbles to get the shirt off. "I just wanna try talking to you."
"That's all you fuckin' do already."
"Please, Kacchan," Deku whispers, putting a hand in Katsuki's hair that stops his ministrations immediately. "Let me tell you how I feel."
Katsuki leans back up and bites at Deku's ear before saying, "Do what you want, see if I care."
Deku smiles—Katsuki can feel a round cheek broadening against his temple. And then Deku's hands are on the hem of his shirt and Katsuki assists in pulling it over his head. Then it's as if their skin is magnetized, pulling toward each other and sticking despite the fact that they're only barely sweating, only just getting started.
Then Deku gently begins to lean Katsuki back, and this time he lets himself go. They're sideways on the big bed, feet dangling off the end and, once again, they are kissing in earnest.
Both of them had been mostly new to kisses—at least ones like this. Kisses that breathe expectation into each other's lungs, kissing that are going somewhere. Kisses where their chins and necks are rolling towards each other the same way their hips do when they're grinding over or into each other.
"You're so handsome, Kacchan," Deku breathes before diving in to kiss Katsuki again. "I'm so lucky to get to have you like this."
The way Deku's jolting back and forth between talking and kissing gives Katsuki no room to respond, snarl, or even glare. Not one that Deku would be able to see, anyway, and then what's the point? It's probably fucking intentional, if Katsuki knows Deku—not letting Katsuki respond so that he can't foil whatever plan Deku thinks he has. Well, fine. Katsuki said he'd let the nerd do what he wanted, so what the fuck ever. He can talk as much as he wants so long as Katsuki gets off at the end of it.
"Can I touch you?" Deku asks, running his hands along the annoyingly thick seam of Katsuki's jeans that's pressing into his thigh.
"Don't have to ask, moron."
Deku just hums as he kisses Katsuki softly and begins unfastening Katsuki's cursed belt. The one thing Katsuki can say is that Deku did dress smarter than him. Just one of his stupid fucking t-shirts and a pair of joggers that has a surprisingly small All Might logo on one pocket. Katsuki can already feel the beginnings of Deku's hard on pressing against his hip. Quick to rise, slow to fall, Deku is.
Finally, Katsuki's belt falls open and Deku unzips his pants. Immediately, Katsuki lifts his hips, staring back at Deku's suddenly rounded eyes. Perhaps it looks overeager, but Katsuki just wants the things off. Now.
Besides, it's hard to look overeager when he's still totally soft in his boxers. It isn't nerves—Katsuki doesn't get nervous. But that uncertainty is seeping through his bloodstream first and foremost, refusing to let his blood divert to where it's supposed to go.
Deku finds out soon enough, placing his palm over Katsuki's front, and if he's worried, he doesn't show it. He just goes back to Katsuki's mouth, licking the bottom lip before meeting in a kiss again and getting to work on Katsuki's cock.
"We don't have to do this if you don't want to," Deku says, the breathy keen to his voice running counter to the sentiment. But there's no doubt to his words. Deku will stop on a dime, trade places if needed, leave the house even though it's his goddamn apartment.
"I ain't a quitter," Katsuki says, bending his legs so his feet are pressed against the edge of the bed, spread with plenty of room for Izuku between.
"Mm, no, never," Deku agrees as he moves further up, his head just past Katsuki's so that Katsuki has to crane his head back, Adam's apple jutting out, in order to catch Deku's lips again. Before he can, Deku pulls just out of reach and smiles. "Kacchan's the strongest person I know."
Then he bends down to kiss Katsuki again, rubbing a thumb across the stretched underside of Katsuki's jaw as his other hand palms the slowly growing tent in Katsuki's pants. Deku's thumb is catching every short blade of hair that coats Katsuki's chin, growing back already from his last shave. Katsuki, intent to give as good as he gets, lifts both hands to Deku's hair, fisting the irregular curls and bringing him down so their mouths are on the same plane again. Then he lifts his hips into Deku's hand, that extra pressure putting a little hitch in his breath.
"Kacchan's so sexy," Deku whispers, pressing his tongue to Katsuki's and squeezing his hand around Katsuki once more before lifting it and diving into his boxers. "So good, getting hard for me like this."
Katsuki wants to squirm. Under the attention, under the words, under Deku. He knew this was the kind of shit Deku would say, and he can take it. Deku has been complimenting him since day one; this is par for the course. Nothing that should rock his world.
He reaches a hand down to thumb at the elastic of Deku's pants. Now that Deku has pulled the head of Katsuki's cock out of his boxers, he isn't going to let Deku get that far ahead in the undressing game. Not when Deku's pants are such that they can just slip down.
Deku obliges, taking the hand that has been admiring Katsuki's jaw and tugging at the back of his waistband before kicking his joggers to the ground. Then Katsuki grabs Deku's ass with both hands and pushes their hips together, streaking Deku's underwear with precum from Katsuki's unclothed cock.
"Hah," Deku shudders, eyes squeezing shut as their dicks rub together. "Kacchan…Kacchan, please, you're so hot, so beautiful, can I please prep you?"
Katsuki's breathing is labored, just starting to lose to the traces of heat rushing to his cheeks and ears. "Fine, but no clothes allowed."
Deku wastes no time tossing his underwear on the ground while Katsuki removes his own. He then reaches for the towel and spreads it out before the two of them twist so that they're situated on the bed properly. Katsuki lies down on the towel and Deku grabs the lube, squeezing some on his fingers and rubbing them together to warm it up.
This is where Katsuki's stomach goes tight. He's been practicing on his own since his and Deku's first time. Practicing stretching and prepping, and trying to train his body into enjoying the sensation, hunting to find his prostate as he jerks his dick in his other hand. He's managed to come and can even fit four fingers inside himself. But it's still felt like little more than shitting in reverse with the bonus of a wet hand on his dick, even when he manages to hit a good spot. There's still something in his ass that doesn't belong there.
Thankfully, Deku doesn't dive right in, instead kissing Katsuki first. Katsuki's liked kissing since the beginning when it impulsively just happened. It was so spontaneous that Katsuki can't even remember thinking to do it—they still can't decide who initiated—he only remembers that once they started he thought Wow, this is fucking incredible.
Deku is lying on his side, perched on one elbow beside where Katsuki is situated on his back. One of Katsuki's legs is sprawled to the side, leaving him open as Deku starts to run the heel of his palm up Katsuki's thigh. The skin is ever more sensitive the further up Deku goes, like he's licking a stripe of increasing heat towards Katsuki's groin. When he reaches the crease of Katsuki's thigh, Deku draws a slick circle on Katsuki's perineum with his thumb.
It's meant to help Katsuki relax, get him used to the touch before things got more intense, he's sure. Deku seems to have done more research since last time too. He keeps circling as the backs of his knuckles begin nudging toward Katsuki's hole, just beginning to rub lube broadly around the outside.
Meanwhile, Deku's distracting him with kisses. The arm that's holding Deku up is framing Katsuki's head with Deku's fingers lazily teasing Katsuki's spikes. Katsuki has one shoulder lifted off the bed as he reaches to keep hold of Deku's cheek, focusing on their mouths. The kissing is good, it always feels good, and Deku tugging at his hair is just irregular enough to keep Katsuki's attention.
But it can't quite hold it as the pads of Deku's index and ring fingers center in on Katsuki's hole, the idle circling suddenly over. Katsuki can't help but tense as the first finger begins to push in, fighting against the suddenly taut muscles of his opening.
"Lean into it, baby," Deku says, "You're doing so well for me."
Katsuki takes a steadying breath as he tries to unbundle his nerves and push his hips back toward Deku as Deku keeps moving forward. The finger slips in easily, as it should from the bit of prep Katsuki did at home and the way he's been practicing. Still, it feels like an intrusion, little more than an uncomfortable pressure. At least it doesn't hurt at all.
"Yes, Kacchan, you're sucking me in so perfectly. I love you so much, you're doing such a good job."
"It's one fucking finger," Katsuki mumbles, trying to focus only on breathing as Deku starts to move it in and out. "Keep going."
Deku murmurs an, "Okay," and pulls out just enough to push a second one in, sucking at the pulse point at the base of Katsuki's neck as he does so.
Two fingers still isn't a lot, even where Deku's fat fingers are concerned. But as they begin to scissor inside, Katsuki wants to clench down, wants to control them, wants it to feel different than it does. The sparks that dance across his prostate shoot right to his dick, but it isn't enough consolation to eclipse the uncomfortable with the pleasurable.
"Look at me, Kacchan."
Katsuki's eyes are screwed shut, but he opens them just as Deku is rubbing a thumb over the wrinkles between his eyebrows. Despite all the things he's doing inside Katsuki, Deku's eyes are firmly on Katsuki's face, brows furrowed and serious.
"Do you have any idea how gorgeous you are, Kacchan?" Deku asks, getting nothing but shallow pants in response. "So, so pretty, Kacchan. Really. I just wanna look at you all the time and I'm so happy you let me. Can we keep going?"
Katsuki nods, his ears beginning to ring as Deku pulls back and adds a third finger. Just as it's going in, Deku's babbling about how good Katsuki looks spread out, how he can't wait to be inside, and how patient Katsuki is being. All three fingers curve into his prostate and Katsuki keens, which Deku says is the best sound he's ever heard.
The best. All Katsuki wants to be is the best, so he lets Deku do what he will, leaning in to where it begins to feel good. His ears are so hot, barely able to stand all the word's Deku's spouting, the praise he's singing. Deku's voice is so damn distracting it's hard to focus on what all else is happening.
Soon, four fingers are in with Deku's thumb squeezing just past the entrance. "Okay," Katsuki says, shivering as a bead of sweat slides from the crease of his bent knee down his leg, "loser, are you gonna do—hah—gonna do this or what?"
"Let's do this," Deku says, curling his fingers in Katsuki one more time before pulling out and wiping his hand on the towel.
Lube has slid down Katsuki's ass, pooling at the small of his back, but Katsuki has long since learned that too much is always better than too little. Deku has spent less time opening Katsuki up than he usually does himself, yet he's more ready than ever. The echo of Deku's fingers is loud inside of him and he wants them replaced before it goes away.
Deku spends a moment putting on a condom—cleanup was impossible last time, so Katsuki insisted on condoms—and spilling more lube all over himself before crawling over Katsuki. He places one arm back behind Katsuki's head and rests their foreheads together as he takes his cock in hand and positions it between Katsuki's legs. "I love you," Deku says, his voice a little quieter than before.
Katsuki nods the slightest bit he can while Deku's forehead is pressed against his. His heart has gone static in his chest and all he can say is, "Uh-huh," hoping that Deku knows what he means.
It seems Deku does, because at that moment he smiles and begins to press in. Katsuki tenses immediately, but Deku whispers in his ear, "Lean in, just like before."
Deku moves his head to the side, laving at Katsuki's ear as Katsuki rolls his hips down. Then it's like Deku's cock is being sucked inside him, like his body wants Deku full to the hilt, hips against hips.
"Just like that, Kacchan—wow, you feel so amazing."
Katsuki doesn't feel amazing. It's so much pressure inside him—no pain or anything, but he wants better than that. He wants it to feel good. He wants so badly for it to feel how it seems it's supposed to feel.
Deku's next motions are slow and controlled. They found out last time that quick snaps of the hip weren't as fun in practice as they were in theory and that long, slower strokes are usually the way to go, at least at first. Katsuki can feel Deku's abs tense against his as he slowly pulls out until just the head remains inside. And then, instead of slamming back in, he thrusts in only a hair faster than he did the first time. That's the kind of control only someone who's spent the many last years honing every muscle in their body can deliver.
"I can't believe I can do this with you, Kacchan," Deku spouts as he slides in and out, a hand holding one of Katsuki's thighs open and stroking it up and down. "You make me feel so good. I only want to make you feel the same, Kacchan, because you mean so, so much to me."
Katsuki sees Deku's collarbone moving back and forth with every thrust just below Katsuki's chin, and he wants to get his mouth on it. He wraps his arms around Deku's back and grabs one shoulder blade, pulling it down to him. Then they're pressed chest to chest, Katsuki's legs thrown back, knees towards his ears so that Deku's collarbone can reach Katsuki's wanting mouth. Deku's thrusts begin rolling just from the hips, his torso holding still. Katsuki licks a freckled swath of skin below Deku's neck and bites down on it, earning a delicious gasp from Deku.
"Yes, Kacchan," he breathes, his next thrust having just a bit more impact than the one before it.
Katsuki preens at pulling such a good sound out of Deku and moves to another spot, just in the hollow of Deku's clavicle. There he wraps his lips around a good spot and remembers the last time he sucked Deku off and how good it had been just to suck. So he alternates sucking and licking until he pulls back to find the spot already purple, looking like a big freckle in the presence of all the other ones.
He's so focused on his task that Katsuki tenses in surprise when Deku's hand snakes in the thin space between their bodies and wraps around his cock. His mouth falls away from Deku's skin, in a gasp, his head hitting the pillow only to be cradled by Deku's other hand.
"There you go, Kacchan," Deku croons. "You look so pretty when you're feeling good, baby. Your face is all p-pink and I can tell just how much we've kissed from the color of your lips. You're just—ngh—the prettiest I've ever seen…"
The babbling washes over Katsuki as that pressure he was feeling before settles into a warm feeling of fullness inside him. He almost wants Deku to stay put and just grind against that good spot inside him, but he's too lost in the feeling to say so. All he can do is wrap his legs around Deku's waist and urge him to stay inside, stay close.
It seems to work and Deku's thrusts are shallow now, but faster. Not quite grinding, but barely leaving Katsuki with every go, like he can't bear to. The hold on his cock is likewise short, nothing but tight, quick pumps just around the head. It sets Katsuki's body ablaze, the towel beneath him damp from sweat.
"Mm, taking me so well, baby. I can feel you s-squeezing around me. Are you close, Kacchan? Please, I wanna see you when you come, you're—hah—so beautiful when you come around me baby, please I wanna see it."
Katsuki whines, wanting to say I'm close, I'm close, don't go without me. But he can't, so he just breathes into Deku's neck, his open mouth occasionally getting to touch the salty brine that's appeared there. The sweat makes his arms slide from Deku's back, so he just grips tighter, digging his nails in so that he doesn't lose an inch of delicious contact. He can't have Deku leave him, not even a little bit.
It's so different from last time. Last time, each touch Deku offered him worked in tandem to get Katsuki where he needed to go. The good sensations lifting the worse ones and the worse ones not so noticeable for the good ones.
This time, each little fire burning within Katsuki from the hand on his cock to Deku's breath hot on his temple spreads to one wildfire so that no touch is separate from another. The innocent hand in his hair feels just as filthy and delicious as the dick in his ass, brushing against his prostate more often than not. Meanwhile, Deku continues to babble over him, like Katsuki is wringing every last word out of him. And Katsuki is feeling good.
This is what he wanted. To feel good and to make Deku feel good. Just both of them in each other's arms and feeling good and yes, yes, yes, yes—
Katsuki can only gasp, eyes flying open as he comes hard in Deku's hand, around Deku's cock.
"Yes, baby," Deku groans, stroking Katsuki through it. "Just like that, just like that, Kacchan. You look so pretty, so, so pretty—you feel so good, so hot, Kacchan, fuck, fuck. Kacchan, I love you, I love you, I—"
The words finally leave Deku as he grunts, stilling as deep as he can with hipbones grinding against sitz bones. All Katsuki can think is that it's good, so good that he's made Deku come like this, that he's the only one who gets to see, gets to hear the filthy words come off his lips. It's his, his, his, and that makes the lingering warmth in his body pool in his chest, gathering there while his extremities begin to go cold.
The hand wrapped around his cock goes first, pressing into the mattress as Deku carefully pulls out, slipping off the condom and dropping it on a corner of the towel before folding it over to be dealt with later. His upper half never moves, an arm still cradling Katsuki's head, chests still plastered together. Katsuki feels the pull against his skin as Deku scoots down a couple inches so their faces are finally back on the same plane. Nose to nose, eyes peering into each other.
Katsuki's eyes are bleary, maybe cross-eyed as he looks up and sees nothing but green. Hot sweat suddenly makes itself known in his hair as Deku slides his arm down to put a hand on Katsuki's cheek, the thumb cold where Katsuki's blush hasn't quite faded.
"Do you feel okay, Kacchan?"
The words pour into Katsuki's head like soap concentrate. It's thick and syrupy as molasses but trying to cut through the sticky gum between his neurons. So it takes him a second for the corners of his lips to spread just a smidge and hum a quiet, "Mm-hmm."
"Good," Deku says.
At some point, Katsuki's arms must have gone heavy and slipped off Deku's back, because now Deku has one of Katsuki's hands in his and is kissing it. The touch almost makes Katsuki want to whine, caught between the hard place of wanting to lean in and push away, like just the simple touch is overstimulating him. He settles for letting his head fall to one side, eyes closing. He's really fucking tired.
His eyebrows furrow as the towel scrapes against his back. It's rough and wet, clammy actually, as his body cools and the towel with him. But his forehead relaxes again as he's left with the soft, dry comforter underneath him. It's enough to make him feel like he's floating on a cloud and those cold, misty water droplets are what's drying on his skin instead of his and Deku's sweat.
Suddenly, a layer of warmth is over him, soft and smelling of detergent. A moment after, something is pressing against his side, nuzzling into his shoulder. He knows it's Deku by scent alone—he's known the smell of Deku's sweat for years, long before they started doing this. It's an old friend and Katsuki noses into Deku's hair, breathing it in unapologetically.
"Mm, sure you're feeling okay, Kacchan?"
Deku's voice is sleepy too now. More breaks, as though his vocal folds have gotten too tired to meet anymore. Like they know that the time for talking has come and gone. Katsuki gives the tiniest hum he can, and it takes all the effort in the world, but he does it.
"Okay. Nap and then dinner, Kacchan."
He is feeling good. His muscles have been wrung out, his brain all but turned off, just waiting for sleep to come over him. Even his ass feels okay—there's no pain to speak of, just an echo of feeling. He's still stretched out, very aware that he'd just coupled with Deku in the most intimate of ways. Actually, he felt that last time and, despite his views on how everything else felt, that was one feeling that he liked. It lasted for hours after, a reminder of what he and Deku did and what it meant for them.
He hopes he can still feel it when he wakes up.
