“Come on Kacchan, just this once! I promise I won’t come on you. Not like last time.”

Katsuki can feel Deku’s hard cock pressed against his ass, firm and warm, the length throbbing and twitching. He thrusts once, twice, and Katsuki shudders, his pussy twitching beneath his hero suit.

“You still smell like sweat from patrol. I can’t handle it. I just want to lick and taste you. Please let me, Kacchan? I’ll treat you so well and make you come so good, I promise?”

Katsuki can’t help but want to give in, push Deku between his thighs and let him lick. It’s not like Deku isn’t good at oral, oh he is, he’s divine, making sure Katsuki comes before Deku ever does, thrusting his own cock into the bedspread as he makes love to Katsuki’s spread cunt, tasting the savory and sweet juices flowing down.

“Deku, it’s been a long day.”

“Please, I promise. I’ll make it so good for you. Please let me make you come!” Deku begs, his eyes shining low in the light of the bedroom.

Katsuki’s heart thrums in his chest, wanting to give in. Patrol had been long and exhausting, and all he wants is to jump in the shower and tuck into bed but the idea of a good toe-curling orgasm has him re-thinking that thought.
He turns over on the bedspread, with his head landing on a soft pillow. “Better be good,” He growls, and Deku doesn’t hesitate before he’s shoving his face into Katsuki’s hero suit bottoms to sniff, breathing in the sweat and musk of a long day’s work and it sends shivers down Katsuki’s spine. He’s never been with someone who got off on his sweat and something about it gets to him, down deep. “Get on with it,” He snarls, but Deku’s too busy shoving his nose in Katsuki’s cunt, still hidden beneath his hero suit, and he groans, tilting his head back.

“Think I could make you come like this? Fully dressed?” Deku murmurs, “I’d like to one of these days, but no, you don’t have the patience for that today,” He huffs, licking a stripe down the suit, and that goes straight to Katsuki’s gut.
He’s full of sweat and grime, but Deku doesn’t care, wants to lick and suck anyway, taste how he drips beneath the suit, and boy he is. His cunt’s juicy already, twitching and ready to go, and Katsuki’s not going to beg for it. He has standards.

Deku’s finally ready, eyes hooded, when he pulls down Katsuki’s suit pants slowly, and reveals the boxers underneath, soaked through with juices. He’s panting like a dog in heat, wanting nothing more than to dive in for a taste.
“Please, Kacchan? Can I?” He begs, licking his lips, “I’ve waited all day to lick your cunt until you come all over my face.”

Katsuki sighs, shifting his hips up for better access, and Deku springs into action, nose pressed into Katsuki’s freshly shaved cunt. He groans, licking a stripe up Katsuki’s cunt, and swirls the head of his tongue around Katsuki’s clit. Katsuki can hardly keep his hips up, caught off guard by his clit being licked so soon, and he twitches.

“Shit! Deku!”

“Sorry, baby.”

Deku swirls his tongue again in apology, and Katsuki groans, pressing his hips up further. He wants more, wants Deku’s tongue deep inside, pressing into every inch of him. Katsuki’s body aches, craves more, heats up with the notion that this is just Deku getting warmed up. Katsuki’s chest’s already heaving, turning a warmer hue, reds speckling his pale skin. Deku probably thinks the color’s pretty, he thinks to himself, shyly, noting how beneath the dimmed lights, the reddish hue still shows up.

Deku’s pressed against his cunt fully now, laving attention on his insides, tongue fully pressed inside, and Katsuki moans, hips grinding up into Deku’s face, wanting more. His tongue presses against every heated bit of him, flicking and swirling, making Katsukki buck and twitch against him.

“Fuck, Deku, just like that! Lick me!” He snarls, hands now fully in Deku’s hair, pulling him closer still if possible.

He cusses, abs clenching as Deku does something with his tongue Katsuki can’t even describe and his head lifts from the pillow to look at Deku, or as much of Deku that he can see, who’s face drips with juices. Katsuki’s that wet, he guesses, slightly embarrassed, but Deku obviously doesn’t care, only coming up for air a few seconds later with a grin on his face.

“Kacchan, you taste so good.”

“Shut up and make me come already.” Katsuki’s head falls back on the pillow, hips shifting back up, cunt twitching. He’s not one to beg, but Deku had been doing something with his tongue that made his insides twist.
“Oh, I’ll do more than that, baby.” Deku grins, sliding a finger into Katsuki’s cunt, and Katsuki groans.

“More. Fucking more.”

The finger curls, twists, and another is added, followed by a third, and they scissor his opening, and Deku’s tongue follows soon after, swirling around Katsuki’s clit, making him scream out.

“Just like that, Deku, yes, please, fuck me! Harder! Faster! I need more!” Katsuki growls, hips grinding along with Deku’s fingers twisting and thrusting, feeling his insides burn.

Deku keeps hitting that spot inside him, so close but not enough, and he’s losing his mind. A tongue keeps swirling, flicking, and Katsuki thrusts his hips up to meet it, snarling and cussing. He needs more than this. He’s so close, just on the edge, if Deku would just-

Deku stops. Katsuki thinks he’s losing his sanity, eyes slightly watering, and he’ll pretend it has nothing to do with the raw emotion of getting fucked until his mind leaks out his ears.
“Deku, what the-”

And then Deku restarts, almost ten-fold, and Katsuki has to wonder if he’s using his quirk, because holy shit. The pace Deku finger-fucks him cannot be real, and Katsuki bucks his hips to meet every thrust of Deku’s fingers, and Deku sucks at his clit real good, enough to make him see stars.

He’s just on the edge, so fucking close, and he shudders, closing his eyes. Every squish and squelch makes him shiver, and the bundle of nerves inside him thrum, alight with fire.
“Deku, if you don’t fucking,” He growls, and that’s it, Deku swirls and sucks on his clit, thrusts his fingers just right inside him and that bundle of nerves sets him off, making him almost set his quirk off, which he hasn’t done since puberty.

He bucks against Deku’s mouth, whining lowly, thighs pressing hard against Deku’s head, leaving him trapped against Katsuki’s quivering, wet cunt, but not like he’d complain. He’s perfectly content, still sucking and licking harder if anything, trying to make Katsuki lose all composure if possible. Katsuki whines, louder still, and groans, cunt twitching against Deku’s face as he comes not once, not twice, but three times. His thighs quake, whole body trembling, cunt throbbing and his cunt’s like a waterfall with his release. He squirts into Deku’s mouth and he opens wide, tongue lapping against Katsuki’s cunt, to accept everything Katsuki offers. Katsuki can’t stand it, body shaking, as he comes down, and Deku pops back up.

“That was so good, Kacchan! You taste so good! Can I fuck your thighs, now? Please? I promise I’ll go quick!” He practically begs with hearts in his eyes.
Katsuki doesn’t have the mental energy to argue, just pulls his top off and tosses it somewhere across the room where it’s a problem for tomorrow, and rolls over onto his stomach, to present his ass and pussy.
“Fuck away, Deku.”

“Oh, fuck, yes, baby. Thank you so much for the food!”

It’s a little late for that, having just practically eaten a full course meal of pussy, but Katsuki won’t argue. He can hear Deku shucking off clothes behind him, fast enough to get an award for “fastest to get naked hero.”
Deku climbs aboard, his hard cock thick and warm against Katsuki’s bubble butt. He thrusts a few times, experimentally, making Katsuki’s cunt twitch. He half-heartedly wonders if Deku’s going to end up sliding his cock in somewhere in between, and Katsuki thinks he wouldn’t mind.

“Push your thighs together?” Deku asks sweetly, and Katsuki cooperates, muscular thighs warm against each other, and his cunt dribbles a little. “There you go, baby. Just like that. Look at those thighs. I love seeing your thighs. I write about them in my notebooks, you know, about how muscular they are. Someday I’d like you to choke me out between your thighs, and make me pass out. I’d like that, losing my life between your thighs. That would be a nice death,” Deku murmurs to himself, and Katsuki’s cunt dribbles more at the sweet-talking. He always liked when Deku talked, and as much as he liked Deku’s tongue between his thighs making him come, sometimes he wondered if just Deku talking could make him come. Deku did talk a lot.

Deku slides his warm cock between Katsuki’s thighs, and his ass jiggles as he thrusts once, twice, Deku sighing softly, sweetly. “This feels so good, baby. I love the feeling of my cock in your thighs. I love when you let me do this. It’s such a treat to be able to feel you this way, your muscled legs wrapped around my cock. Mmm press a little harder, yeah just like that. Oh, that feels so good. Can you feel me twitch against you? I’m so hard for you, baby. That’s all for you. I only get this hard for you, only ever have. I don’t think anyone else could get my cock this hard and dripping except for you.”

Sometimes, on patrol, Katsuki loses himself in Deku’s voice on comms because he talks a lot. He tends to ramble, usually, as it is, so Katsuki’s used to it, but on patrol, Katsuki has to control himself so he doesn’t get hard just listening to Deku’s voice. It wouldn’t be good if he somehow Pavlov’s dog’d himself into getting hard just by hearing Deku’s voice. But in bed, listening to Deku’s sweet murmuring as he fucks Katsuki into oblivion, Katsuki understands how he possibly could.

Deku’s thrusting fast now, cock dripping between Katsuki’s thighs and cheeks, and Deku doesn’t stop to adjust Katsuki anywhere, so he’s thrusting where his cock presses into Katsuki’s cunt, and it makes him groan.
Katsuki hisses, biting his lip, trying to control his noises, and Deku murmurs, “No, baby, let me hear you,” softly, and Katsuki stops biting his lip, letting out each, “Ah, ah, ah” out loud instead of muffling them or keeping them inside. “Yeah, baby, I like to hear you. Do you like it when I fuck you like this? Do you wish I just slid my cock inside you and fucked you deep?”

Katsuki groans, low, but stays quiet. He won’t admit that he does wish that Deku was doing that now, fucking his drenched cunt instead, each thrust against his cunt absolutely driving him mad.

“Oh, Kacchan. I love fucking your thighs, but I love fucking you, too. I love when my cock’s deep inside you, feeling how warm and drenched you get for me and knowing it’s all for me,” Katsuki hisses as Deku adjusts, spreading Katsuki’s cunt so that his cock slides against it with each long thrust. “I love watching you ride me, watching how your muscles twitch with every thrust of my cock. Would you like that, baby? My cock inside you?”

Katsuki’s had a long, sweaty day, and he’s not shocked when Deku shoves his nose deep into Katsuki’s armpit and sniffs. It does, however, make him shiver.

“Deku, what the fuck!”

“It’s so good. You smell so good, baby. Shows you did so good at work today, got all sweaty for me. Can I have a taste? Can I?”

Katsuki snarls, refusing to say a word. He’s too busy shoving his blushing face into the pillow and trying to muffle every grunt and whine, cunt twitching against Izuku’s cock. He’s close to coming again, just from the friction, and he wants more, but he won’t stoop so low as to beg.

Deku flicks out an experimental lick, and Katsuki full body shudders, feeling it in his entire body. He heats up, almost using his quirk to burn through the bedspread.

“You taste so good, Kacchan. So musky and sweet. I want to taste every inch of you. Would you let me?” Deku mutters, flicking out kitten licks against Katsuki’s, very much sweaty armpit. “Do you like that, Kacchan? Does that feel good? It feels good to me. You can feel my cock twitch with every lick.”

Katsuki almost has to pull him out of his armpit, bodily dragging him out, “Deku, what the fuck?”

“You taste so good, Kacchan! Please? Can I have more? I need more of you. Just another taste!”

“No more of my armpit, you freak! You’ve had enough!” Katsuki’s flushed down to his toes by now, “You’re so fucking weird, you know that.”

But it’s like Deku entirely forgets as he continues to thrust like an animal between Katsuki’s thighs, each thrust making Katsuki’s sweet cunt quiver.

“Can I make you come like this, Kacchan? I can feel you, you know. You like this too.” He thrusts, experimentally, and Katsuki whines into the pillow, hips shifting to meet Deku’s, “Just like that. Does that feel good for you? I want to come so bad,” He hums, “Maybe if I do this?”

He reaches down, and swirls a finger around Katsuki’s clit, making him freeze for a second. He’s not expecting it, and he full-body twitches. Katsuki groans lowly again, hips shifting to meet Deku as he grinds against him.
“See, just like that. I can treat you so good, Kacchan. Can I make you come? Would you like that?”

Katsuki lifts his head, long enough to snarl, “God, fucking get on with it you-”

But he doesn’t have long before the combination of Deku’s fingers and thrusts have him twitching, bucking his hips and crying. His insides twist, on fire, and his cunt flutters against Deku’s cock.
“There you go, baby. That’s it. Come for me, just like that, so good, that’s it. I love watching you come, Kacchan. You look so beautiful under me.”

Katsuki shifts his hips, whining, “Get on with it and fuck me already.”

Deku grins, a man on a mission. “No complaints here, Kacchan.”

Katsuki flips Deku over on the bed, and straddles him. “My fucking turn.”

Deku grins up at him, “I love seeing you like this,” he sighs, “So fucking beautiful.”

Katsuki doesn’t waste a second before he’s sliding Deku’s cock inside him and he rolls his hips experimentally once, twice, and Deku’s eyes nearly roll back into his head. Pathetic, of course he’d lose it this early. Katsuki braces himself on the headboard before he’s lifting himself up, rhythmic in his motions, and falling down onto Deku’s cock hard.

“Holy fucking-”

Katsuki loves hearing Deku curse. It’s rare, with him being the whole “Symbol of Peace” thing, he rarely does since he has to look and act the part. He’s usually so chaste and pure, but with Katsuki, he’s just Deku. It’s nice, and also, satisfying knowing he corrupted their sweet little Symbol of Peace.

“With you doing that, you know,” Deku groans, hips grinding up to meet Katsuki’s every motion, “I’m not gonna last.”

Katsuki grins down at him and only ups his pace at the comment, like it’s a race on who can come first. He’s so sensitive, barely able to handle the feeling of Deku hitting that sweet spot at every thrust so he knows he won’t last long either, but he also won’t give Deku the mercy of slowing down.

“You can do better, Deku. Come on, you’re really going to come first?”

“With you doing that?” Deku braces his hands on Katsuki’s hips, and he squeezes, “Yeah, I’m not going to last.”

“Poor little Deku, can’t handle a little pussy riding,” Katsuki taunts, and with that, grinds down harder, faster, and Deku whines.

“Come on, Kacchan!”

“You tellin’ me you’re gonna come for me already? Gonna squirt that big dick inside me? Make me feel how much you want me?” Katsuki snarls, “Yeah, you’re gonna come inside me just like I want you to.”
They never did bother grabbing a condom, not with Katsuki’s impatience, and Katsuki knew he’d regret Deku coming inside even though it felt good every time. He liked the feeling, warm and wet, but cleanup afterwards always tended to piss him off. Oh well, that was for later him to deal with. Horny Katsuki was at the helm for now.

“Come on, Deku, give it to me,” Katsuki growls, grinding low and deep, Deku’s cock hitting every inch of him perfectly and it made him quake and quiver. He cupped his chest, tweaking his nipples, “I know you can make me come like this; feels so good. Love riding your fat cock. Bouncing on it like this for you.”

“You’re gonna kill me, Kacchan.” Deku groans and warns, “I’m close.”

“Good, because I’m close too. Better hurry up with that cock of yours and make me come.”

Katsuki grinds himself onto Deku’s cock, feeling it twitch inside him, and he feels his insides curl. He’s almost there, so close. He’s on the edge and on the verge of coming. He tweaks a nipple while Deku swirls a finger around his clit and that’s all it takes. He falls forward towards Deku, kissing him wet and nasty like he likes, and comes. He whines into the kiss, his cunt fluttering around Deku’s cock and he feels Deku come too, twitching deep inside him with his release. Deku’s abs twitch as he comes, and he sighs into the kiss.

They break away and Deku sighs, “Wow, Kacchan.”

“Just wow?”

“I’m dripping with you and all I get is “wow”?”

“Sorry, Kacchan. My brain’s a little fried. You let me lick you until you squirted on me, fuck your thighs and fuck you. Sorry if I’m a little braindead!”

Katsuki grins, “Yeah, well, I’m great, so.”

“The best of the best, Kacchan. Holy shit.”

Katsuki gets up off Deku, and grimaces, “And now the fun part.”

“Sorry about that, Kacchan. I should’ve grabbed a condom. That’s my bad.” Deku apologizes, getting up to grab a rag to clean up Katsuki. “Here you go.”

Katsuki cleans up slowly, energy slowly coming back, but the exhaustion from his long day now long gone and fucked-out. The worn-out exhaustion has now been replaced by a new, bone-deep exhaustion that goes down to his toes, one that only comes after a good fuck. He’s exhausted, but in a good way, and feels a lot better than he did before.

“Run me a bath?” He asks, laying back as Deku wipes him down.

“That’s the plan. One bath, coming up, and I’ll even order dinner while you’re in the bath. Sounds good?”

Katsuki has no intention to cook anymore today, so he shrugs, “Fine with me. I remember the last time you cooked, and we had to throw the pan away.”

“Kacchan! It wasn’t that- okay yeah it was that bad. There’s a reason you cook.” Deku grimaces, “I don’t want the building to have to call 911 again thinking our apartment is on fire.”

“See, there you go.”

Katsuki shoos him off towards the bath.

In all, it’s been a good day. He had a good, yet exhausting day on patrol, and Deku just took him to cloud 9. He lays back against the bed, waiting for the bath to be done.

It’ll be interesting to see what future awaits them, or at least tomorrow.
