Work Text:
Katsuki is about ready to chuck his damn laptop across the room by the time he finishes up his work. Everyone and their mother needs to send him so many asinine emails about shit that doesn’t matter, they’re training two new interns who fucked up on three of his reports that he then had to hunt down and fix, and he’s exhausted after patrol, and just…it’s a lot.
He’s just glad it’s over now so he can go find his boyfriend and forget about work for a while.
Carefully not throwing anything across the room, he gets up and makes a quick detour into their bedroom to change. It’s warm, so he decides to simply forgo pants entirely, instead sliding on one of Shouto’s hoodies. It hits Katsuki’s mid-thigh and makes him feel small, but not in the way that would normally make him prickle and snap. Instead, he just feels…soft, maybe. Safe.
Not that he’ll ever admit that out loud.
He pads over to the living room, but it’s empty and dark. Same with the kitchen and the bathroom. Katsuki frowns and retreats to Shouto’s office, peering in the cracked door to see him still hunched over his desk. Dammit.
He nudges the door open; Shouto tilts his head when he hears it creak, but doesn’t look away.
Katsuki grumbles under his breath and stomps into the room. Shouto spins in his chair, looking tired as he starts to say something. Before he can push out one syllable, Katsuki climbs into his lap with a huff, wrapping his arms around Shouto’s neck. He can feel his boyfriend stiffen for a second before arms hesitantly wrap around him.
“Hey,” Shouto murmurs. “Is everything alright?”
“Shut up,” Katsuki mutters. “Shitty day. Are you fucking done yet.”
Shouto softens against him, rubbing his back. “Soon. Another hour, at most.”
Katsuki grumbles again. That’s not fucking soon. He grinds his teeth, resisting the urge to just drag Shouto away from work.
Fingers card through his hair, making him shiver and slump a little.
“I’ll go as fast as I can,” Shouto promises. “Just relax.”
And another time Katsuki might be annoyed at how easily Shouto reads him, but he’s a little too tired for that act right now. He just nods into his neck and closes his eyes, breathing in a scent like woodsmoke in winter, relishing in the warmth of a body against his. Usually after a bad day he’s volatile and angry and craving a fight, but something about Shouto like this makes him go boneless.
He doesn’t know how long it is, minutes or hours, before Shouto makes a soft sound and shifts a bit in his seat. Obviously he’s trying to get comfortable, and Katsuki feels a little sting of guilt shoot through him as he makes to get up, get out of the way.
Shouto holds him in place with one arm. “Don’t go anywhere, love, you’re fine.”
Katsuki reluctantly settles, only to tense all over again when Shouto’s thigh presses up against his cunt. He breathes in, waiting for Shouto to shift again, but he doesn’t. It’s not like he’s moving, it’s not like Katsuki came in here looking for anything but his company, but suddenly he’s aware of how close they are and how warm he is and his hips twitch without his permission, dragging his clit over Shouto’s leg.
“Baby,” Shouto murmurs.
Katsuki freezes. Right. Shouto’s working, Katsuki doesn’t get to hump him like an animal any time he wants.
Then Shouto moves his leg again, and it has to be deliberate. Katsuki gasps in his ear, fingers involuntarily tightening in his shirt. He swallows, but can’t make himself relax.
“Sorry.”
“Did I tell you to stop?” Shouto asks, rubbing a soothing hand down his back while moving his leg in slow, teasing motions against Katsuki. “Take what you need. I don’t mind.”
God, Katsuki shouldn’t be so emotional just from that—that voice. He barely said anything. Somehow his eyes burn anyway and he slowly starts to grind on Shouto’s leg. A soft whimper slips out of him before he can stop it—he swears it’s not supposed to feel this fucking good—and he buries his face deeper in Shouto’s neck to keep himself quiet.
“There you go,” Shouto says almost absently, the soft sound of a keyboard mixing with Katsuki’s too-audible breaths. “Good boy.”
Katsuki whines; he can’t help it. That’s all he ever wants, really, is just to be good, and it feels like a balm after the day he’s had. Shouto is petting him and holding him and his scent is everywhere and he thinks Katsuki is good— it’s embarrassing how he starts moving his hips faster, heat coiling in his core as he bites his lip to keep quiet. He’s wet enough that he can feel his boxers sticking to him. He’s going to make a mess of Shouto’s pants in a second.
The thought punches a soft, breathy moan out of him, the loudest sound in the world compared to the quiet of the office. Shouto has barely moved since they started, calm and collected while Katsuki comes to the brink.
“Please,” he whispers. “Sh-Shouto, I’m—can, can I–”
“I told you, sweetheart, whatever you need,” Shouto says, and it’s the pet name that tips Katsuki softly, gently over the edge, biting on Shouto’s collarbone as he trembles through his orgasm.
He doesn’t stop moving, though, trying his best to hold back all the noise building up in his throat as pleasure mixes with overstimulation.
“Good boy,” Shouto murmurs again. Katsuki shudders. “You want to cum again?”
“Yeah,” Katsuki breathes. “Yeah, it feels—f-feels really good.”
Shouto’s hand finds its way to his hair, petting and then tugging gently, urging his face up. Katsuki pouts, protesting the distance. Then Shouto leans in, kissing him gently, at odds with the filthy way Katsuki is rutting against him, and he can’t really complain about that.
“I’m glad,” Shouto says, so close that their lips still brush as he talks. “I always want you to feel good.”
He leans in again before Katsuki can respond, kissing him until he’s flushed and dizzy and barely moving anymore, unable to focus on both things at once. Shouto takes pity on him, moving his leg again and doing most of the work.
It doesn’t take long for Katsuki to finish again. Shouto tries to pull away when he notices, but Katsuki chases him, something like panic sparking in his belly at the thought of stopping even for a second.
“Baby,” Shouto mumbles into his mouth, “hey, you can take a break, you don’t have to–”
Katsuki shakes his head, cutting him off. Shouto’s clothes are soaked under him and his legs are shaking but he can’t stop, he doesn’t want to.
“Okay, you keep going, I have you. whatever you need.” Shouto’s hands slide up under his shirt, and Katsuki tilts his head back, no longer trying to hide his panting. “You’re so pretty, sweetheart, that’s it, don’t hide anything from me.”
Katsuki’s next moan is loud, because he wants to be good.
“Not that you can, when I can feel how wet you are down here.” Shouto slides one hand down so that Katsuki grinds over his fingers instead, and he can hear the slick sounds of their bodies moving together.
A little sob falls out of him when the hand pulls away. “Sho—Shouto, please, please please please–”
“You’re gonna cum again already, princess?”
Katsuki nods, fast, his vision blurring, because once he starts crying it’s really hard to stop. His hands are clenching and unclenching around Shouto’s shoulders as he thrusts faster, but he’s not really getting there on his own and it’s frustrating.
“Please, please I wanna…I can’t– ”
Shouto coos at him, but it’s the opposite of condescending. “Oh, baby, you can’t get there on your own?”
Katsuki shakes his head. “No, can’t, please, ‘s not enough, wanna cum.”
“I have you,” Shouto says, grabbing his hips and moving both his leg and Katsuki’s body in a perfect rhythm. “Let me make you feel good, that’s it, don’t worry about doing any of the work. You’re my good boy.”
Katsuki is just dizzy and warm everywhere, barely able to process how good everything feels as he clutches at every part of Shouto he can reach. He whines, leaning their foreheads together, but he can’t manage to do more than that with Shouto controlling his pleasure now. It washes over him in waves until he can’t tell what’s happening anymore, can barely manage to hold his head up or his eyes open.
He can feel his mouth moving, mumbling Shouto and feels good and please and more and thank you, and Shouto is murmuring mindless praise back at him all the while.
After what feels like years, he hears himself crying, registers that what he’s feeling is at least half pain—though right now even that is its own kind of pleasure—and hears Shouto ask, “One more, baby, can you give me one more?”
Katsuki doesn’t know if he can, but he wants to, he wants to give Shouto everything, so he nods and what’s left of his senses fizzles into white.
————
Katsuki has some vague, fuzzy images of being carried, a warm, indistinct voice in his ear, but he doesn’t really register anything until his hoodie is being tugged off and he whimpers.
“Shh, you’re okay,” Shouto tells him. “We’re getting you in the bath. You coming back for me?”
Katsuki nods and leans against him, too tired to hold himself up. Shouto lifts him and lowers them both into the water, back to chest, guiding Katsuki’s head back to rest on his shoulder.
“Oh, you’re so swollen,” he murmurs sympathetically.
Katsuki lifts his head enough to see his hand sliding toward his pink folds, all puffy from the stimulation. He twitches when Shouto touches him, whining in protest.
“Okay, I’m sorry,” Shouto whispers, kissing his temple. “We’re all done. You were so good for me, you know that?”
“Yeah?” Katsuki asks. It comes out a little more vulnerable than he wanted. Everything seems to, with Shouto.
Shouto kisses him again. “Of course. You’re always perfect. Beautiful. You came five times, did you know that?”
Katsuki shakes his head, a little dozed. He twists to look at Shouto’s face. “Did you…?”
“I got everything I wanted,” Shouto says firmly. He wraps his arms around Katsuki’s waist and squeezes, gentle. “And I’m not letting you go for the rest of the night.”
Katsuki settles back down with a contented sigh. He can live with that.
