(This is an AU where Kiyoomi and Issei are brothers)
Kiyoomi fondly watches Atsumu playing with his niece, making silly faces to make her laugh and indulging her silly tricks, light pheromones dancing in the air around them in delight.
âMama! Puppy, puppy!â she squeals, stuffing her fox plushie under Atsumuâs sweater.
âYer really excited to become a big sister, arenâtcha, Akari-chan?â
Akari nuzzles her cheeks against Atsumuâs faux baby bump, promptly wincing in distaste when she picks up on the alphan scentâKiyoomiâs scentâdrenching Atsumuâs clothes. âStinky!â her face contorts with genuine disgust, her tiny nose wriggling adorably still.
âHaha! Uncle Omi reeks, doesnât he?â Atsumu playfully coos, releasing his pheromones. He hoists Akari in his arms and perches her on his lap, the little girl immediately seizing him in a big, warm hug and burying her nose in Atsumuâs l scent glands, giggly breaths tickling his neck.
From the other end of the couch, Kiyoomi rolls his eyes and scoffs, arms folded over his chest, helplessly endeared but foolishly jealous of Atsumuâs special bond with his brotherâs daughter.
âSo possessive, Kiyo-chan~â Tooru teases in a singsong, emerging from the kitchen with a whole tray of baked muffins, fresh out of the oven. âTheyâre just having fun. Donât get mad at my babies,â he adds, knowing fully well Kiyoomi absolutely hates it when he uses the pet name for his omega.
Kiyoomi lets out a disgruntled groan.
Behind Tooru, Issei chuckles and wraps his arms around his mate, rubbing soothing circles on Tooruâs round, bulging belly. Tooru twists his neck and gives his alpha a kiss on the lips, short and sweet.
âMommy and Daddy are flirtinâ!â Akari gasps as she hides her face in her hands, mindlessly mimicking Atsumuâs accent in excitement.
âOf course we are, darling!â Tooru huffs, utterly shameless. âHow do you think did mommy get pregnmrph-!â
âNot flirting, sweetie. Love love!â Issei shoves a muffin into Tooruâs mouth to shut him up.
Akari peeks between her knobby fingers, then she lunges into Atsumuâs arms and tackles him in an embrace. âLove love!â
Atsumu snuggles into the small bundle of joy, holding her tight.
Kiyoomi sighs, defeated yet uncontrollably fond.
When honey eyes meet his own, they share a wordless understanding through fervent gazes, heavy and sultry and /aching/ for each other. Longing for something theyâve always had close, but not quite their own.
Theyâve been ready for a while now, so itâs no surprise theyâve reached a tipping point.
Kiyoomiâs inner alpha howls in anticipation.
A silent promise is conveyed in mellowed scents, which doesnât go unnoticed by the other pair of fated mates in the room. Issei and Tooru turn their heads with matching mischievous looks, snickering, catching the shift in Kiyoomiâs temper.
But Kiyoomi could care less, for his mind is set on one thing alone: whisking Atsumu away and taking him home.
For tonight, Kiyoomi is a man on a mission.
