"grrr." Kiyoomi growls under his breath. Feeling a tiny body leaching onto his back. Then tiny hands tugging on his beautiful black curls as he let's out a little yelp from the sudden pull, earning a satisfied giggle from the little boy that was on his back.

"WAKE UP DADDY!" Hikari shouts loudly at his father's ear.

"Ugh gimme 5 more minutes." Kiyoomi said groaning, then going back to his peaceful slumber. The curly head male was snoring away but his son had other fun ideas planned in his little smart head. Like the devil himself, he snickers and kiyoomi hears it but he doesn't think much of it so he continues to sleep.

After a few good ol' minutes, kiyoomi hears something or more like a little someone rummaging through a cabinet so he sat up slowly, rubbing the tiredness from his eyes as he looks around his room. No one was in sight so he looks over to his cabinet and spots a devil playing with his things. "HIKARI SAKUSA STOP RIGHT THERE YOUNG MAN"

"NUU THIS IS WHAT YA GET FER NOT WAKIN UP!" Hikari smirks evily as he pulls out all of his father's face mask and cleaning products all over the floor. Then getting to another cabinet as he shoves all of Sakusa's boxers and briefs everywhere and even aiming them at his dad's head.

The alpha sighs loudly then gets out from his comfy bed. Him only in his black and red colored boxers as he lazily picks up all the things that his son sprawled onto the floor, grabbing at his curls stressfully as his son continues to make a mess so he cries. Like literally cries as his son didn't even bother to comfort his dad and continue to make a mess.

On FaceTime:

"BABY HE'S A MONSTER!" the alpha cries out loudly, his face was all puffy from crying so the other male on the phone just chuckles at the taller man.
"didja piss him off omi?"
Kiyoomi gasp and looked at his screen with a big pout. "He was the one wo made a godamn mess with all my things and he even disturbed my beautiful sleep! I cry because I wanted to see your beautiful face when I woke up but no- god was being a bitch and the devil himself was right in front of my face instead!"
"sakusa kiyoomi how dare ya call my son a devil! Now open up the fucken door-"

Atsumu ends the call as kiyoomi hurriedly ran towards the door, as their son clings onto his leg while he opens the door to reveal his lovely sweet omega holding some groceries in his arms. "Are ya just gon stand there and watch me? or are ya gonna help me out kiyoomi?"

There's two things going on in Kiyoomi's head at the moment. One: atsumu only calls him kiyoomi when they're in bed. Or two: atsumu also calls him by his first name when he's mad at him. So it's best that Atsumu was the second one right now since the alpha could feel his omega's hard glare at him so he immediately grabs the grocery bags from the blondes arm and sets them down on the kitchen counter top.

"My little Hikari~ are ya giving yer father a hard time?" Atsumu picks up the little boy as he snuggles his face in his neck, then trailing butterfly kisses all over the kid's face. "do ya want yer daddy ta spank ya for being bad?"

Hikari shook his head, hiding his face onto his mother's neck as his little arms wrapped around the omega's neck. "daddy doesn't even spank that hard anyways.."

Atsumu raised his eyebrow, looking at his son fondly as the alpha on the other side of the room was glaring at the little boy. "Hehe~" Hikari stuck his tongue out at the alpha when his omega mother wasn't looking, only angering the alpha even more as he trots his way over to them.

"My atsu" Kiyoomi hugs the back of his omega's waist, his chin resting on the shorter's shoulder as he stakes his claim on the blonde.

Hikari glares back while clinging onto his mother's neck, bringing him closer to him. "Mine!"

"Nu uh mine" Kiyoomi fires back, pushing the blonde closer to him before Hikari stands up and jumps on his dad, surprising both males who were caught off guard.

"Grrr, mine mine mine!!" Hikari growls just like his dad, his baby fangs revealing itself as he pounces on him, before getting ready to bite his dad but was stopped when Atsumu gets ahold of his shirt and lifts him up from the angry alpha.

"What did I tell ya bout biting daddy?" Atsumu scolds the baby alpha who looks down defeated, his ears flopping down as he listens to the omega scolding him.

"look at me Hikari" He looks up and spots his mother face inches from his.

"You were supposed ta beat him up with the metal bat I boughtcha! yenno go sangwoo on his ass??!" Atsumu encourages his son who perks up at the mention of the metal bat.

"W-what- Atsu baby why are you guy's teaming up again me??!" Kiyoomi backs up as he watched his lover and son look at each other with a smirk before charging at him.

"I'll buy you guy's whatever you want! Please have mercy on me Atsu and Hikari!"
