Someone send help I can’t stop thinking about an abo #krtsk #kurotsuki where they’ve been dating for a while, long enough that kuroo has came down to help with tsukki’s last two heats(heats and ruts are like every 3 or so months here), BUT he keeps refusing tsukki’s help for his

Rut. He says that he’s not himself and he doesn’t want to hurt tsukki or do something tsukki doesn’t want and tsukki is like you dumb idiot do you think I’m myself when I’m in heat? You think I’m like desperately begging for your knot 24/7?? And kuroo is like yeah lol? & tsukki

Punches his arm but after weeks of cajoling and pestering kuroo agrees to let tsukki come down for his next rut but like makes him sit through a giant lecture of how it’s not him, it’s his alpha, and he understands if tsukki never wants to help him with his rut again and tsukki

Is just like???? Shut up I love you?? So he takes a weekend off and travels to kuroo and Kenma’s apartment, and kuroo is in pre-rut and overly possessive, demanding tsukki shower off the scents of strangers from the train and insisting on scenting him in the living room as the

Three of them watch a movie. When kenma goes to bed tsukki asks if kenma is staying in the apartment and kuroo says yeah, they’ll mainly be in Kuroo’s room but kenma will be there to like cook or w/e cause he’s used to helping take care of kuroo during ruts and tsukki is like

It won’t freak you out that there’s another alpha here? And Kuroo’s like nah he’s pack. He wouldn’t touch you. And then they also head to bed but middle of the night Kuroo’s rut hits and tsukki wakes up to a completely different kuroo. He’s got tsukki pinned face down to the bed

With his body weight, his teeth clamped around the back of tsukki’s neck not hard enough to break skin but hard enough to remind tsukki he could, and he’s pumping the room full of his pheromones, languidly grinding his cock against tsukki’s ass through their shorts. Tsukki,

Already feeling himself start to drip out slick, asks ‘kuroo, is it your rut’ and kuroo growls low and deep and tells him ‘that’s not my name. That’s not what you call me.’ And tsukki’s heart(and dick) leap, and he calls him alpha. Kuroo told him he could be borderline feral

During his ruts and he wasn’t exaggerating. He keeps him pinned to the bed, smothering him in his scent, rocking his hips down the entire time until tsukki is begging for it. He feels like he’s in heat with how bad he’s aching for Kuroo’s knot, and kuroo finally relents,

Growling ‘my omega’ before using one hand to push their pants down and slamming inside tsukki. He fucks him rough and hard, biting along his shoulders and neck, sucking marks as he goes. He does retain enough self control to not pierce the glands on tsukki’s neck though, but he

Does tongue at them until they feel more sensitive than tsukkis cock, uselessly trapped between him and the bed. He doesn’t stop even as tsukki cums, clenching around him, and tsukki can’t hold back the almost scream like moans and babbles of alpha, tetsu, please, your knot,

Please, until he finally cums himself, knot buried as deep as he can. Tsukki didn’t know kuroo could cum this much, feeling like an impossible amount was filling him up. That’s how the first day is spent, Kuroo’s cock barely leaves tsukki’s hole, even when kenma comes in with

Portions of dinner for them, tsukki’s face bright red as Kuroo’s body barely hides the way tsukki is split open, locked onto kuroo once more. They spend so much time fucking or sleeping, Tsukishima almost loses track of time until his phone blares, an alarm to take his

Suppressants so his heat doesn’t start, but kuroo refuses to let him leave the bed. When he tells him what he needs, kuroo stalks over to tsukki’s bag and tosses it forcefully into the hallway. (He did warn tsukki before that he wasn’t sure he was going to be able to stop himself

From not letting tsukki take them, and tsukki agreed to the risk of being without them. He was on a monthly bc shot so the only real risk was the inconvenience of adding a few days on.) kuroo refuses to let tsukki out of his bedroom and bathroom, refuses to leave his side. They

Take baths together so kuroo can keep him scented the entire time. And then tsukki feels it, the warmth tingling through his body. He groans when he realizes what’s happening and kuroo looks at him in concern, and tsukki is like my heats coming. I feel like. To which kuroo

Replies by yelling for kenma and tsukki is like ?? The fuck??? But Kuroo flips them around so tsukki is behind him, pressed against the wall by Kuroo’s back, and when kenma opens the door he must be able to smell tsukki because he stops in the doorway. Kuroo tells him that

Tsukki’s about to go into heat, and asks for him to just bring a cooler of drinks and prepackaged food and leave it inside the doorway because despite being pack, he was not letting another alpha get that close to his omega in heat. Kenma nods, rolling his eyes, but he does as

He’s asked and when tsukki’s heat hits before Kuroo’s rut is fully over, kuroo is insatiable. He fucks him what feels like nonstop, their only breaks when he’s knotted tsukki once again. It’s a barrage of ‘so good for me, my perfect little omega, made for my cock, wanted it so

Bad huh?, fucked your heat right into you? I’ll fuck it out of you don’t worry. My omega, made for my cum. I’ll fuck you full, so fucking full of my pups.’ Tsukki is so incoherent with pleasure he barely remembers any of his responses, but he’s sure he’s as desperate as kuroo is.

Kuroo’s rut, prolonged by tsukki’s heat, finally starts to fade and the next time tsukki wakes up, it’s to his normal kuroo, his sweet beautiful boyfriend who’s tracing patterns onto tsukki’s back, peppering his face with kisses. ‘Just a little more, we’re almost done, you’re

Perfect. So perfect.’ Tsukki whines at the praise, and the last few times are slow, languid, syrupy sweet. When they both finally are out of it, kuroo has to carry tsukki to the bath. He keeps apologizing until tsukki shuts him up with a kiss, calling him a stupid alpha, there’s

Nothing to be sorry for. He’d be there for the next rut, and the next, and the next, for the rest of his life.

Bonus points: Yama shows up to try and check on tsukki when he’s there longer than expected and isn’t answering his phone and kuroo refuses to let him see him, until tsukki promises that yamaguchi is a beta who is part of tsukki’s pack and he can stand in the hallway. Kuroo only

Agrees if tsukki lets him knot him first, and he barely lets tsukki’s head peek out from under him to talk to yamaguchi. He also growls the whole time, and tsukki rolls his eyes but assures Yama he’s fine, really.
