#skts Not-so-single father Kiyoomi x Teammate Atsumu | Fluff x getting together (sorta 😚)

Firsts of Many

Kiyoomi was exhausted, he had been exhausted for almost 10 months now. Ever since his ex dropped off his newborn daughter.

He was in over his head with her, having not the slightest idea what to do with such a small human, but he was lucky. His friends and family were all there for him, helping him learn and gifting him tools he didn’t even think to buy.

But none was there more than his setter, Atsumu. The blonde barged in one day, a declaration of “I’m gonna be the best fucking uncle ever,” and he just never left.

It was unspoken, the part where Atsumu never left. The constant “don’t worry bout it omi, get a nap in before

I leave” always turned into “it’s too late to drive and you’re exhausted, just crash here, Atsumu,” ended up turning into a toothbrush in his bathroom and space in his drawers for clothes that weren’t his own.

Even now, Omi lay on his couch, dressed in a freshly washed (thank you, Atsumu) hoodie and sweats, gazing out sleepily at the blonde sitting on his floor with his daughter.

Atsumu was dressed similarly, in nothing more than a stolen hoodie and a pair of shorts.

His legs spread wide while he sat on the blanket that had on the floor.

Akiyo, his darling girl just turned 10 months, sat on the other side of the blanket. Pure focus upon of little features as she stuck her bottom into the air, her hands supporting her as she attempted

to stand on her own.

“Sleep,” Atsumu spoke, shoulder bumping into the side of the couch where Kiyoomi lay. “Last night was rough.”

Last night was rough, a change in Akiyos food had her crying all night with a tummy ache. He threw the rest of it out just this morning.

“I’m fine…” Kiyoomi even sounded awful. He let his gaze linger on Atsumu, watching his profile. His freckles had just started to fade as the winter months crept in. It was such a shame.

“Oho, she’s up.” Kiyoomi snapped back to his daughter. She stood, not too steady,

Her arms out to her sides as she pinched her face in concentration. She wobbled before teetering just a little too far to the left and plopped right back down on her bottom, the wind pushing out of her in a sweet “oof”

“Aaaand she’s down again.” Atsumu smiled, watching as

Akiyo paused, looking to them both to see if she was hurt. Eyes wide in shock of her fall. At the lack of reaction both men gave she just giggled, rolled over, and pushed up again.

She’d been doing this for what felt like weeks. Trying to stand, latching onto things, and

falling. She had gotten pretty good at holding onto the couch and bouncing on her little legs, it was only a matter of time before she took those first steps.

“Seriously Omi, get some sleep. I promise to wake you if she takes her first steps,” Atsumu was speaking softly,

almost as if he were trying not to wake him.

Omi adjusted himself slightly, laying on his side so he could keep an eye on Atsumu. “Promise?”

Kiyoomi was met by a dazzling grin, Atsumu turning to face him. “Of course, I wouldn’t let you miss that.” There was such sincerity in

his eyes that Kiyoomi couldn’t help but smile back. Letting the weight of last night slowly pull him down he nodded. But before he could even get his eyes closed, a hand was hitting his chest.

“Omi!” Atsumu sounded urgent, his gaze once again returning to his daughter.

She was standing again, but unlike before she wasn’t teetering so much. Her right foot was already placed slightly ahead of the other. Her brow furrowed as she looked from her foot to Atsumu before swinging her left leg forward- and she didn’t fall.

“Oh my god-“

Kiyoomi sat up, exhaustion melting from him almost instantly. She looked at Atsumu with a dazzling little smile, like she had just cracked a code.

“Oh my fucking god-“ her right foot came forward and soon she was toddling right up to Atsumu, giggling as she

face planted into his chest.

“Oh my god!” They both yelled, Kiyoomi laughing in absolute disbelief. Atsumu wrapped her up in a hug and squealed with her, kicking his legs out.

“She did it!!” He turned, sending an absolutely breath taking smile towards omi.

Kiyoomi felt on top of the world, his baby girl just walked! He couldn’t ever remember feeling this way, not even winning gold at the Olympics with Atsumu at his side. No, this was the moment, Atsumu beside him, clutching his baby girl close.

He couldn’t stop himself, his hands coming up to cup both of atsumus cheeks, leaning in and planting an giddy little kiss against his lips. It was quick, barely even a peck, but it sent an absolute shock of electricity down his spine. His cheeks heating up instantly.

Kiyoomi had no time to think about what he had done, too excited about his daughters first steps to even consider thinking about impulsively kissing his best friend.

He got off the couch, crawling to the opposite side of the blanket and plopped himself down.

Tapping the floor between his legs he grinned.

“Akiyo? Wanna come to daddy?” Kiyoomi watched, cheeks aching from his smile. He saw the stunned Atsumu slowly turning Akiyo around to face her dad. She got the memo, the little look of determination on her face.

She stuck her tongue out slightly, a habit he had to have picked up from Atsumu. Their little focused faces were exactly the same. Her first step was wobbly, gently guided by miyas hand. But soon she took a couple more steps, giggling to herself as she trotted up to omi and

collapsing into his chest. He felt his tears burning the back of his eyes, threatening to fall as he clutched his baby to his chest.

“You did it!” He cheered, her own squeal of delight matched his own. “Okay! Okay- Go to Papa,” he gently plopped her down, turning her to face

the man across from them.

When he lifted his gaze, he saw what he could only describe as love in Miyas golden eyes. Eyes brimming with unshedtears. Sniffling, he nodded and held his arms out.

“Come to Papa..”

Miya was there for a lot of Kiyoomis firsts. His first nationals-

Though they were opponents. He was there for his first Division 1 game- this time as his teammate. He was there for his first Olympics. But he was also there for his daughters firsts. Her first laugh, her first steps, and even her first words. And he planned to be there for many

more to come.

But most importantly, Atsumu was his first. His first love, his first co-parent, and most importantly his first, and only, husband
