Work Text:
Katsuki isn’t an idiot.
He knows how you’re supposed to court an omega.
He knows they’re precious little things, with precious little feelings, and precious little pussies that you have to work open on your fingers nice and slow, and the thing is—
The thing is that he didn’t give a single fuck about any of that, before Shouto.
Being an alpha didn’t hurt.
People respect alphas. People make way for alphas. People don’t ask alpha pro heroes about their ruts on national TV.
And Katsuki was fine with that. With being lucky, if nothing else. (With being chosen, maybe, when he felt smug.)
And then Shouto decided that Katsuki’s lap was his favorite napping spot, and Katsuki’s life swiftly rearranged itself to cater to one (1) spoiled pretty boy’s whims.
And now Katsuki cares.
And now Katsuki’s teeth itch, and he dreams of Shouto pinned underneath him and whining alpha, and he wakes up sweaty and overheated, more often than not with come staining his underwear, and then he ends up having to surreptitiously do his own laundry at, like, three in the morning.
And tonight he’s not alone for it.
He walks into the laundry room with his sheets all bunched up in his arms, only to find candy cane princess bent over in front of one of the machines.
“Oh,” he says. “Hi, Bakugou.”
That’s rich of him. Calling him Bakugou now, when they’re alone, like he doesn’t whine Katsuki while tugging at his sleeve with everyone else no more than three steps away in the common room just because he wants homemade cold soba for dinner for the third time that week.
(And the embarrassing bit is that batting those long eyelashes at him is usually all it takes to get Katsuki to cave.)
“Had pressing laundry matters to attend to?” Katsuki asks, even if he’s no better off himself.
Shouto’s cheeks flush with heat. “Um,” he says. “I had a dream. I think my heat might be due a little sooner this time around?” And then, a little softer, gaze darting away, “You were in it, you know.”
“Half ‘n half,” Katsuki says, “are you washing your sheets because you got them messy with slick?”
He hears how he sounds. Truly, pathetically fucking delighted over an omega who regularly uses him as a body pillow and a personal chef getting his pink, strawberry pattern sheets wet with slick while dreaming about his knot.
That’s—
That’s gotta be, like, cause to suspect temporary insanity, right?
“Mm,” Shouto says. “I woke up so—you know that for a second, I thought my heat actually started. So since they were already messy, I kind of—made them messier?” He bites his lip. “Is that bad?”
It takes Katsuki a second too long to put together that half ‘n half is asking him if waking up all needy and pent up and choosing to rub his pussy about it was wrong.
“Did it help?” he blurts. “Do you, uh, feel better?”
Shouto shrugs. “I’m not sure,” he says. “I always wonder what if would be like if I had an alpha. That’s silly, isn’t it? Do you really think it hurts? For your first time? I even have these, uh, special toys Momo made for me, when I told her the school-sanctioned heat aids were kind of uncomfortable, and they feel good, it’s just—it’s not real, you know?”
“You want it to be?” Katsuki asks. “With an alpha?”
Shouto nods. “Mm,” he says. “It’s usually you, actually. The alpha, I mean. Up in my head.”
“Yeah?” Katsuki says, throat dry. “Is that why you’re so clingy?”
“I like your scent,” Shouto huffs. “I like it—I like it when you let me tuck my face into your neck and breathe in. Sometimes I just want to fall asleep like that.”
“I know.” Katsuki laughs. “And you do, you spoiled brat.”
“I like you,” Shouto says. “Aren’t alphas supposed to be nicer to you when you tell them that?”
“Dunno,” Katsuki says. “I’m just here to wash my sheets because I got come on them, princess.”
Shouto’s pretty eyes get all wide. “Oh,” he says, teeth digging into his lower lip again. “Like—because of me?”
“Pretty much,” Katsuki says resignedly. “Yeah. You happy?”
Shouto nods. “Mm,” he says. And then he steps closer, and he says, “Can I see it? Your knot?”
“Here?” Katsuki asks. “You wanna see it in the damn laundry room?”
“Well,” Shouto says. “You can wash your sheets first, obviously. You’ll have to wait for them anyway.”
Right.
Obviously.
Katsuki shoves the damn things in the nearest empty machine so quickly he barely sees what buttons he’s pressing. And then he pours the laundry detergent straight from the bag like a heathen. No scooping. And then, finally, he presses the start button.
And then he’s alone.
With Shouto.
“There,” he says. “Happy now, princess?”
“I’m always happy when you’re around,” Shouto says, and the horrible thing is that he sounds so fucking earnest about it, and he’s probably not even joking, not really, even if he’s definitely still teasing Katsuki, the bastard, and—
And, regrettably, Katsuki is a stupid knothead alpha, and when Shouto’s around that might end up being just the thing that kills him.
“You’re trying to do me in, huh?” Katsuki asks. “Anyone put you up to this?”
“Nuh uh,” Shouto says. “But Tamaki-senpai did offer me a crisp 10000-yen bill just last Tuesday if I would somehow figure out a way get you to stop glaring at him during joint training exercises. He said I was free to use my omega wiles. And he stared at the wall the whole time.”
“Don’t call him Tamaki-senpai,” Katsuki huffs, teeth gritted.
“But,” says Shouto, head tilted to the side, “his name is Tamaki and he’s my senpai?”
“Still,” Katsuki hisses. “You make it sound all—you know.”
“What?” Shouto asks, his head still tilted to the side, like a damn cat. “Is this also about my omega wiles?”
Katsuki pinches his wrist. “Behave,” he says, “you brat.”
“I think you like me anyway,” Shouto says. “Or you wouldn’t make me cold soba and pick up my favorite yoghurt from the store whenever you go. Or have to wash your sheets at three in the morning.”
Right, well—
They’ve already established the (not-so) temporary insanity thing.
“That’s why you should let me see your knot,” Shouto continues. “I want to know if it’ll fit. And you’ll probably stop getting your sheets dirty.”
“Probably,” Katsuki repeats. “Right. You have great faith in me, princess.”
Shouto shrugs. “Well,” he says. “Sometimes you can’t help it. I like—you know. Doing it with a pillow between my thighs. That way my hand doesn’t cramp up.”
Sure, yeah. Of course he rubs his clit like a princess too. Fucking figures. Katsuki will never, ever go through the night with dry sheets again, at this rate. It’s fucking embarrassing.
And his teeth still itch.
So, yeah, it’s most definitely something like temporary insanity, the thing that makes him reach forward and cup Shouto’s squishy cheeks with one hand and say, “You gonna let me watch if I want to? In exchange for your cold soba?”
Shouto shakes his head. “No,” he says. “I’d let you watch if you just asked.”
But Katsuki didn’t ask.
Katsuki, the idiot that he is, has never once asked for anything. Because he was so convinced up in his head that he wasn’t courting Shouto, that Shouto didn’t even want to be courted, and he kept telling himself he wasn’t going to climb up the walls just for the possibility of getting some omega pussy.
And now they’re actually talking about Shouto’s pussy, and Katsuki is very much climbing up the walls.
(He should probably stop squishing him, if nothing else.)
“Take ‘em off,” he says. “I wanna see.”
Shouto blinks. “But I asked you about your knot first,” he whines, petulant like a child. “How is that fair?”
“Good omegas listen to their alphas,” Katsuki says. “So be a good omega, sweetheart.”
“Now you want to be my alpha?” Shouto says. “I’ve been throwing myself at you ever since I presented.”
Katsuki blinks. That’s—
That’s definitely news to him.
“I thought you were—dunno. Being clingy because you were full of hormones and you knew I wouldn’t assume shit?”
“Assume?” Shouto repeats. “Like what? That I touch you because I want to? That I want you to touch me back? Horrible assumptions to make, yes. Wholly baseless, even.”
“My bad, princess,” Katsuki says. “I guess I was just trying not to be a creep.”
Shouto arches an unimpressed eyebrow at him. “So you were just going to keep washing your sheets at inadvisable hours?” he asks. “For the rest of your life?”
“No,” Katsuki blurts. “Eventually, I figured we could move in together and I could, like, offer to help with your heats because it’s convenient.”
“Mm,” Shouto says. “That’s romantic. I should have just let Tamaki-senpai whore me out for 10000-yen.”
“Don’t say it like that,” Katsuki huffs. “Damn brat.”
“Katsuki,” Shouto says then, very seriously, “do you want to take off my panties or not?”
“Yes,” Katsuki says. “Yeah, I definitely—yeah, half ‘n half. I want to take off your panties.”
“After your laundry finishes?” Shouto asks. “Or is this a more pressing matter?”
And—
And just for that, Katsuki scoops him up, and something a lot like alpha pride wells up in his chest when Shouto obediently wraps his arms around Katsuki’s neck and lets out this soft little oh.
“Um,” he says. “What are you doing?”
“Isn’t it obvious?” Katsuki says. “I’m taking you to bed.”
And once he’s in Katsuki’s bed, Katsuki will lay him out and lick at him until Shouto leaves scratches down his back and begs him for a knot, a real one, so he’s nice and full, and then—
Well.
That part’s probably gonna be easy. He just has to keep him forever, and take care of him for just as long.
But, right now, Shouto looks at him, and he asks, “Do you have a spare set of sheets?”
Katsuki laughs, can’t help it. “Not gonna let me fuck you on the mattress?” he asks. “Not even if I ask nicely?”
Shouto shakes his head. “Nuh uh,” he says. “Not for my first time.”
And that’s—
Yeah, that’s right. It’s Shouto’s first time. His first time with an alpha. His first time with Katsuki.
No pressure. Nope. None at all. It’s just—
Katsuki better make it damn good for him then.
“What about the second time?” he teases. “Is that more acceptable?”
“Depends,” Shouto says, nose scrunching. “We still have to see if it’s going to fit.”
Right. There’s that too.
“Can I kiss you first?” Katsuki asks. “I think I wanted to do that since the first time I saw you, I just—didn’t fucking realize. And you hadn’t presented yet, and—shit, halfie, I’m real stupid, aren’t I?”
“Just a little,” Shouto says. “But you’re my alpha, so it’s okay.”
And then he closes his eyes, and he leans in, and Katsuki meets him halfway. And he tastes sweet. And Katsuki’s half in love and three quarters gone, and completely done for, so even the little jingle going off to signal that Shouto’s laundry is done doesn’t ruin it for him.
“Bed?” he asks, just to check.
Shouto nods. “Mm,” he says. “I’m sleepy. And we should cuddle.”
“Brat,” Katsuki laughs. “Who spoils you, huh?”
“I don’t know,” Shouto says. “It might take some time to figure out. You know, serious research. We should do it somewhere comfy.”
“Yeah,” Katsuki says. “We should.”
So he takes his spoiled omega to bed. So he can kiss him some more on clean sheets.
Because those, evidently, are very important.
(Because everything Shouto wants is, and Katsuki is gonna do his damn best to give it all to him.)
