#sakuatsu pregnant Omi part 21

Atsumu comes home after his post match shower and interviews. He looks sheepish, likely from reading the text that Kiyoomi had sent him regarding his on-court behaviour, but any lecturing Kiyoomi had planned to do vaporises at Atsumu's scent.

He's freshly washed, but there's the slightest hint of sweat from his climb up their building's stairs (he refuses to use the lift for bullshit pride reasons), and it's driving Kiyoomi absolutely feral.
"Wha--?"
Atsumu doesn't manage to get a full word out before he's being--

--shoved against the door and kissed aggressively.
He's clearly confused, and honestly Kiyoomi is too. He has no idea why Atsumu does this to him and it can't all be pregnancy hormones.
Whatever. That's a conundrum for when Kiyoomi isn't this rabidly horny.
"Omi?" Atsumu asks--

--dazed as Kiyoomi starts unbuckling his belt and then awkwardly sliding down to his knees.
"I'm going to suck you off."
Since Miya Atsumu is never one to look a gift horse in the mouth, whatever question he was going to ask is clearly shelved in favour of pushing his underwear--

--down to his knees.
Kiyoomi is not an especially big fan of giving oral, and he's also not very good at it, but since the sudden urge to get Atsumu in his mouth hasn't subsided he's going to do his best.
And his best is rewarded by some of the most erotic noises he's ever heard.

From this position he's surrounded by the scent of Atsumu's thigh glands and he's getting high on the musk. Kiyoomi wants to spend the rest of his life surrounded by this smell.
There's a hand in his hair too, and while he's previously been annoyed at this action (his previous--

--boyfriend liked to use it as a way to thrust down deeper) he finds Atsumu's fingers gripping his curls to be oddly comforting.
Eventually Kiyoomi loses feeling in his feet and he has to pull of Atsumu's cock.
"Bed," he demands, thrusting a hand at Atsumu so that he can be--

--helped up. "Bed now."
"What's gotten inta ya?" Atsumu asks as he's pushed towards their bedroom, awkwardly trying to step out of his underwear and shorts at the same time. "Not that 'm complainin', I really ain't complainin'."
"You need to behave on the court," Kiyoomi snaps--

--pulling his leggings off. "You almost lost us the game by baiting Tsukasa-kun like that. It was stupid, careless, and do it again with Ushijima next week."
He sinks down onto Atsumu's cock and it's everything he's been missing. Fuck, they fit together so perfectly. Kiyoomi--

--isn't able to move fast with his belly, but Atsumu catches on quick and holds him up so that he can thrust into him.
"Ya liked watchin' me make a fool o' myself?" Atsumu grins. "Or is it that'cha like me bein' jealous?"
He's keeping up a perfect rhythm and pace so Kiyoomi can--

--only moan in response. He doesn't have a good defence; because it's absolutely true. He likes that Atsumu gets territorial over him, like he's something precious to be guarded. It's an absolutely cave-man-like reason, but there's no helping it when that's just how he feels.

"Iizuna-kun and some of the others are gonna come over here before they go out," Atsumu says, running a hand up to Kiyoomi's chest. "Imma make sure that ya stink of me, have me still drippin' outta o' ya when they're here."
Kiyoomi moans, curling his fingers against Atsumu's--

--chest. It's a filthy idea, gross and disgusting to be so obvious about their sex life, but the thought of it is sending Kiyoomi rocketing towards orgasm.
He cums over Atsumu's stomach and slumps over onto him, shuddering with overstimulation as his alpha chases his own relief.

"I'm sorry that I'm not able to have a proper dinner with you," Kiyoomi says to Iizuna.
"It is very understandable given your condition," Iizuna reassures, because he's a wonderful and understanding friend. Kiyoomi can't imagine staying for a cup of coffee with someone--

--permanently in pyjamas and stuck on a sofa and actually enjoying it. Even Motoya has drifted away to the kitchen after the obligatory pleasantries.
He had a shower before their friends came, and he made Atsumu join him, but Kiyoomi knows there's a dark bruise on his throat--

--that Atsumu sucked onto him in a petty act of possessiveness while they were under the water, and every so often Iizuna's eyes flick down to it.
Kiyoomi knows why. He's always been vocal about disliking marks of any kind during sex, but with Atsumu... it's just different.

"I had hoped the be active until I delivered," Kiyoomi sighs.
"Pregnancy is complicated and I'm glad I don't have to go through it; both you and my sister have had a rough time with it. But it's supposed to be different every time, if you ever wanted another, I suppose."

"I'm focusing on this one at the moment." It's hard not to, kicking his ribs is their current favourite pastime. "Although I suppose it depends on how many children Atsumu wants."
Atsumu grew up with Osamu, it's highly likely that he'd want his child to have a sibling. Iizuna--

--is looking at him curiously and Kiyoomi cocks his head.
"What?"
"I thought you and Atsumu weren't together, just co-parenting."
"It's... complicated."
As soon as he says it, Kiyoomi realises that it isn't complicated in the slightest. If he was ever to have another baby it--

--would be with Atsumu, and only Atsumu.
Oh. Oh fuck.
"Excuse me," Kiyoomi says, getting to his feet with difficulty and waddling off to find Atsumu wiping down a spill in the kitchen.
"Heya Omi-kun."
"I'm in love with you."
"Sorry about the spill, Atsumu-san, I'm going to leave-

--and find Komori-kun!" Hinata says, and then bolts out of the kitchen.
When Atsumu doesn't say anything, Kiyoomi repeats himself.
"I'm in love with you."
He's starting to worry that the silence is because Atsumu has changed his mind and that Kiyoomi has just made an idiot of--

--himself. He's waited too long and missed his chance after jerking Atsumu around for so long.
But then Atsumu smiles and comes to wrap his arms around Kiyoomi.
"Took ya long enough." He kisses the side of Kiyoomi's head. "I am gonna make ya tell that ta everyone though."

Kiyoomi scowls and pushes at Atsumu's chest.
"I am not."
"Nah, ya have ta get my Ma ta like ya now, so yer gonna have to be real expressive about yer undying love fer me."
"You're making me change my mind," Kiyoomi threatens, but Atsumu just laughs.
"No, ya ain't, ya take ages--

--ta make a decision but when ya do, yer sure 'bout it. I know ya, Omi, ya can't fool me."
"Fine," Kiyoomi says grumpily while nestling his head in the crook of Atsumu's neck. "But it means I'll say it to your face less."

TBC! Coming up to the end soon.
