just a short #sakuatsu ft.#osasuna
a/b/o prompt because i just got well

"20,000¥ and I'd say its a boy" Osamu smirked

"50,000¥ and I'd say it's a girl" Kiyoomi countered

Both alphas are in front of the table with light drinks on their sides and their wallets ready to cry

"Nah, Kiyo. 70,000¥ and it's still a boy. Yer child's gonna be a boy and he's gonna inherit everything from tsumu and yer gonna have to take care of him till you have arthritis" Osamu states, not blinking nor wavering

But Kiyoomi isn't having it,

"100,000¥ and my one year cleaning supplies. It's a girl and she's gonna be like me."

Goodness, he loves Atsumu but to have a miniature version of him running in their house is already too much to think of

Osamu smirked, "Deal. Just wanted ya to raised the price. Either way it's still Tsumu's child so the pup's definitely will be like their mama"

Kiyoomi cursed, fuck he's screwed.

He totally didn't thought of that.

But he can't lose, not to this annoying creature called his brother-in-law.

So he smirked and dropped his wallet on the table,

"Right, i'm guessing it's the same thing for you since it's Rin's child as well" Bingo

Osamu's face paled

Kiyoomi internally laughed, if Atsumu is a menace then Rintarou is always beyond that.

And Osamu happened to married him

"Till death do us part, fucker"

Looks like it's really them fullfiling that vow

Because 2 months later, both Atsumu and Rin gave birth at the same day, at the same room at the same hospital and of course at the same time

And they both have twin boys

Their twins literally have everything the same on their birth certificates aside from their names

And that takes them to where they are now,

Kiyoomi fixed his headband that his eldest is trying to bite while his youngest kept on crying and hugging his legs

The only consolation for what he's feeling right now is seeing Osamu on a worse state than him with his youngest ripping his shirt and his youngest drawing what seems like Rintarou's mad face on his boxers.

Osamu spotted him and raised his middle finger towards Kiyoomi's direction before his shirt got completely ripped and catching his child who slide down

Kiyoomi mouthed, 'fuck you' but before he can laugh he felt his pants getting pulled off his legs by his youngest, still crying

Atsumu and Rin were out on an appointment but their Instagram post made Kiyoomi and for sure, Osamu as well lost the light of their day

[In caption] "Just got back from the O.B looks like Pup #3 is otw" Attached with two sonograms with Atsumu and Rintarou's name, respectively

If Kiyoomi and Osamu had a duet session with howling and crying that night then it's just normal

Till death do they part, after all
