#omega!kiyoomi
Kiyoomi saw an omega approach Atsumu and he's never nocked an arrow faster

Tidy, organised omega Kiyoomi 'accidentally' dropping his used panties on the locker room floor right in front of alpha Atsumu...He overheard the him talk about calling some omega over tonight and rather doing the sensible thing of confessing to Atsumu he prefers torturing the alpha instead ❤️

kiyoomi calling him a perv as if his omega didn’t feel giddy at that 😤

omega kiyoomi blushing a pretty red as alpha atsumu proudly puts his slick filled panties in his pocket

alpha atsumu whispering in omega kiyoomi’s ear of all the thing he’s going to do to him later, kiss /all/ his pretty moles and stretch him full of his knot etc., while his hands roam kiyoomi’s body and kiyoomi feels slick soak his panties

alpha atsumu starts growling possessively whenever he spots a pretty omega he wants and suna always has to hit him over the head like a dog to get him out of that trance. just atsumu getting an especially rough hit and going OUHHHH while omega kiyoomi glares at him and keeps walking. silly puppy..

exactlyyyy 😌 paving the way for omega kiyoomi, we’ll get you out of there!!!

Omega nerd Kiyoomi shyly tugging down the hem of his new, shorter school skirt because delinquent alpha Atsumu hasn't been able to take his eyes off him all day and keeps teasing him about finding out what's underneath it 😍 (don't ask him what possessed him to buy it because he will lie)

a thought: atsumu’s alpha teeth growing when he smells the slick of omega kiyoomi like the way vampires do when smelling blood

not ready to post a snippet BUT extra context, it's dystopian omegaverse au where alpha bokuto and omega kiyoomi are in an arranged marriage and it's the two of them trying to take back their true natures in a world where alphas are repressed though nefarious means 😤💕
editing a bokuomi omegaverse fic at the moment, might post a snippet once I'm happy with it 👀

atsumu can't be around kiyoomi without wanting to be fucked senseless by him, it's mortifying. hes good at his job, he should have been the one promoted to Kiyoomi's position - would have been if he wasn't an omega, if he wasn't an asshole (probably), if he wasn't the office slut (previously wasnt)+

kiyoomi wants to scent him, claim him. he is the boss. in some ways, the leader of this pack, and in his stupid alpha brain that means he gets to take his pick of pretty omega to be his mate - okay, maybe it is his primal instincts taking over. but its ridiculous. kiyoomi has always been in control+

omega kiyoomi in yesterday’s pajama shorts and calf high white socks and a milk stained tshirt (that belongs to his alpha) and clips in his hair to keep his bangs out of his face…

atsumu has never been more turned on by his wife before in his life.

grabbing a beer so many times, and watching volleyball matches together at Kiyoomi’s flat. The amount of light touches Kiyoomi leaves on Atsumu, and only Atsumu, no other intern, no other Omega.

“Just do the check up, please.”He adds quietly.

They stay quiet. Kiyoomi rounds the bed and stands right in front of Atsumu. His pheromones are crazy right now. The Omega doesn’t understand how no one has scolded Omi for not changing the patches.

He takes away the hand from Atsumu’s back and Omega wants to whine. Probably some people in this situation wouldn’t want to be touched. But he wants to, especially if it’s Kiyoomi. Or Osamu. “Should I call other omega doc-“
January 7, 2026 at 10:41 PM
“Well, then good you got here, now you have a chance. But I will appreciate if you don’t.” Kiyoomi stands right in front of him with a tiny flashlight in one of his hands, the other one rests on Atsumu’s cheek. It’s so warm, and comforting. It makes feel omega like he’s about to explode.
