Chapter Text
“Oji-san.”
Sukuna looks up when Yuuji calls him. He has a cigar in his mouth, tank top on with his tattoo showing. Sleeves of various designs, and inspired japanese prison tattoos from the Edo period. “What?”
Yuuji shakes his head, and kneels down to poke at the toddler on his Uncle’s lap. “How’s it been being a Father?”
Sukuna grumbles. “Hate that witch.”
Yuuji chuckles. His uncle has always taken pride in never having children. He’s been fucking around, and living his life to the fullest since he was young. Even when he babysat Yuuji as a child, he’d have Yuuji with him at a bar with a glass of milk or in a matching leather jacket when they’d ride on his motorcycle.
The child didn’t favor the Itadori blood which made Sukuna double down that the child wasn’t his, but between the court order blood test, and having Uraume run a few tests of his own, it all came back conclusive that the child was indeed his.
“He’s cute.”
The kid was one year old. Name Kenma. He had a tiger onesie on and comfortably laid his back against Sukuna’s stomach while drinking from his sippy cup. Yuuji hasn’t gotten a good look at the kid until now. He was always at college while getting updates from his Uncle during their weekly phone calls.
He was home for the summer with one year left to go until he graduated.
The backyard was filled with the Itadoris, and some of their friends and neighbors. A barbeque to celebrate the summer.
“S’not as cute as you were as a kid.” Sukuna says. He puts his hand on Yuuji’s head, massaging his scalp as Yuuji looks up at him.
Yuuji blushed, and smacked his Uncle’s hand away. “Stop.” He mumbled.
Sukuna snicked, and took his cigar out of his mouth. “Gonna hang at my house this summer? I’ll need more help since I have a kid now more than your parents will need you.”
Yuuji leaned into the kid's face to sniff him. Smelling only Sukuna on him. “I thought you were doing shared custody?” Kenma paid him no mind as his personal space was invaded.
“Naw, I got full.” Sukuna chuckled. “The fuck I look like asking for permission over my kid. Play stupid games, win stupid prizes is what I told her.”
Yuuji stood up. Leaning against the table next to Sukuna’s chair. There were two empty chairs he could sit on, but he liked being close to Sukuna’s lap.
Always has.
Sukuna put his cigar down on the ash tray, and tugged on Yuuji’s shirt. “Sit down. Let me scent you.”
Yuuji fell easily onto his Uncle’s lap. The family was used to their closeness. No one paid them any mind as Sukuna rubbed his cheek over Yuuji’s scent gland. “Suprised no Alpha hasn’t tried to claim you, brat.”
“Oji-san, you say that every time I come back.” For an Omega he was a hefty size, but in his Uncle’s lap he always felt small, and cared for.
Delicate.
Wanted.
Sukuna slid his hand under Yuuji’s shirt, resting his hand on his abs. “You’ve gotten stronger. We’ll have to spar later.”
Yuuji hums in agreement. “Still can’t believe you’re a dad.”
“Shit me too.” Sukuna shrugs. “S’not bad though. Reminds me of my time with you. Even your little crew of knuckleheads that would eat me out of house and home.”
“That’d be Todo.” Yuuji reminds.
“Oh, sure.” Sukuna said with sarcasm.
Todo, who was over by the stereo, changed the music to his favorite idol’s new song.
He heard Megumi and Nobara groan.
His parents chuckled. Used to Todo’s actions. They’ve taken Yuuji and him to a few of her shows when they were minors.
Sukuna wouldn't, no matter how much he begged. He drew the line at Idol music.
“You unpacked?” Sukuna asked.
Yuuji shook his head. “I did some laundry, but had a feeling I’d lounge around for a week or so before I did so.”
“If you stay with me. I’d pay you to watch the kid while I work.”
“You already gave me money.” And paid for his books, subscriptions, and phone.
“I’ll buy you a car. If you watch the kid, you’ll need to get around.”
Yuuji looked at his Uncle.
Sukuna looked back at him.
See it was stuff like that that made his secondary gender feel too safe. His parents protected, loved and provided for him, but Sukuna was an individual that he couldn’t help but compare any he dated too.
It was wrong.
But fuck, he would love to spend one heat with his Uncle.
Just once to say he did it. So he could actually start to create a list of traits he wanted in a long term partner.
The kid wasn’t helping matters either.
With Kenma being too young to have his own scent, he smelled only like Sukuna, and if Yuuji stayed there for the next three months, his brain would have a hard time separating at the end of the season.
Especially if he makes a nest.
“Uh, let me think about it.” He said quickly. His tone went up slightly at the end as Sukuna’s hand scratched at the top of his pubic hairs above his belt.
Sukuna hummed.
Eventually Kenma needed to get changed, and Sukuna gently pushed Yuuji off his lap as he took the toddler inside to change him.
Yuuji took that opportunity to go sit with his friends. They were eating, and talking with Gojo, who he didn’t see coming in.
By the time the party was coming to an end. Sukuna had left early to put Kenma to bed, and he had work in the morning.
Yuuji spent the rest of the evening paying attention with one ear. His mind elsewhere, thinking if he should go to his Uncle’s tonight.
Just to hang out.
Maybe test the water of making Kenma breakfast.
It was around midnight when he got a text.
“The code has changed. 33213.”
From his uncle.
"The spare bedroom was turned into Kenma’s room. Don’t wake me up if you come tonight.”
He stares at his phone. He’s in the kitchen now. Everyone is gone, and he was putting the leftovers away.
“You still have that shitty couch? You know I hate that Alpha design.” He texts back. He rubs his eyes. That’s going to be one of the first things to go if he spends the summer there.
“Your Uber will be there in 15. And who said you’d be on the couch, brat.”
Yuuji almost throws his phone into the garbage disposal.
