Summary: When he was younger, he told people Sukuna was his twin, then his brother and now his grandson. At the sweet age of 83, Yuuji, with a missing arm that he lost on a mission in his 50s, sat on his rocking chair in the early morning.
He had woken up before Sukuna, his bastard demon who has endless excuses for never leaving him even after getting his own body. You'd think as one gets older the people around them would be nicer.

When he was younger, he told people Sukuna was his twin, then his brother and now his grandson. At the sweet age of 83, Yuuji, with a missing arm that he lost on a mission in his 50s, sat on his rocking chair in the early morning.
He had woken up before Sukuna, his bastard demon who has endless excuses for never leaving him even after getting his own body. You'd think as one gets older the people around them would be nicer.
Sukuna acts the worst.
The stares they get when Sukuna yells at him in the grocery stores when Yuuji wants something that goes against diet, is mind numbing.
Yet, the item in question will end up in the house at some point.
"Why the fuck don't you have a blanket on you?" Sukuna walks onto the porch. An afghan that Megumi's husband made for him one birthday a few years ago rested in his hand.
He throws it at Yuuji.
With his one arm, he's able to cover his body.
"Better?" Yuuji goes back to rocking back and forth.
Sukuna grunts at him. "Take better care of yourself."
The chair squeaks with Yuuji's movements. "I will."

"Sukuna." He whines. He's crouched over the dead body of their beloved pet. A small cat they found as a kitten and nursed back to health.
Dexter was always found in the crook of Sukuna's neck when they slept.
The stairs creak as his demon descends them. "Why are you crying? So damn loud." He says the last part to himself.
He walks over to Dexter's bed outside the kitchen's doorway. He pauses. Looking at the old man sniffing over the creature. Sukuna doesn't waste tears over weak creatures.
Bending down, he scoops Yuuji into his arms. The old man flays about in his hold, crying.
Very ugly cry.
"It's cold down there, idiot." He holds the sorcerer bridal style. Yuuji rubs his face into Sukuna's chest. The demon can feel the snot seeping through.
Disgusting.
"Where do you want to bury it?" Sukuna asked.
Yuuji sniffs. "Can we cremate her?"
Sukuna was thinking the same thing.
"Why not just bury her and be done with it? Wasting my money on a weak creature." He looks at their pet. Thinking about the last ten years they've had her. His stupid human was resting on the couch with flu the day he found her. Somehow she ended up on their lawn crying, and instead of waiting for Sukuna to get home from the store, he went outside and picked her up.
Sukuna had to make two doctor appointments that day. Then they had to get the house cleaned because she brought fleas with her.
"Please." His wrinkled face pleads to Sukuna.
He kicks the cat, just to make sure she's dead.
She jolts up and Yuuji screams, flaying in his arms again.
The cat blinks at them.
Sukuna puts Yuuji down, then crouches down in front of the cat. Then claps loudly.
It doesn't flinch.
He looks over his shoulder, staring up at Yuuji. "She's fucking deaf."
Yuuji smiles, and with the help of Sukuna's shoulder, sits on his shins to pet her.
Sukuna goes into the kitchen to make breakfast.
Another fucking day in their household.

Yuuji stays in bed.
Sukuna does too.
They're curled together watching a true crime documentary about Gojo. He's jealous of how his teacher looks, the same bright white hair, but it's longer now. Similar to how his friend Geto wore it.
"What are you going to do when I die?" He's half asleep, Sukuna's body runs warm.
"You aren't."
Yuuji laughs. "All humans die."
"Not my human."
"So you're claiming me now? Should have married me then." Megumi had a beautiful wedding. He was low key jealous that he'd never have that.
"We share blood. What would marriage prove?" Dexter is curled on his neck. The overweight cat continues to think it's a kitten.
The doctor said she was fine. Just old age.
Yuuji shrugs. "I want to tell people I love you."
Sukuna groans. "But I don't love you."
"Maybe not in the human way." Mumbles Yuuji.
Sukuna didn't have a response.
They stay silent after that. Sukuna only leaves the bed once to make some hot cocoa for Yuuji. "Don't make a mess." He warns before putting Dexter back in her spot.
The following morning, when Yuuji is pouring his coffee, Sukuna comes up behind him and asks a question.
Resting his hand on Yuuji's waist. "If we get married, it'll be traditional. That western shit is an eye sore."
Yuuji takes a sip. But backs his hips back slightly against his demon's cock. "What's the catch?"
He laughs into Yuuji's white hair. "You haven't forgotten how to bargain." He says. "We're moving."
Yuuji pauses. Cup still pressed against his lips. "I like the city."
"It's too fucking loud and you barely visit the school anymore as a mentor."
But everything is so close. Sukuna's going to want them isolated behind some fancy gate.
"That's not fair."
Sukuna backs up. Yuuji puts his cup down before turning around.
"You've been wanting to get married since forever, I offered it up and now you pussy out!" He's heaving. His arms are spread wide in frustration.
Yuuji stays calm. "I said it's not fair. That's not a no."
Sukuna looks unconvinced.
"I just don't want to be on a mountain. I still want to be within walking distance of a store."
"Mountains are nice." Sukuna urges.
"I'm old."
"But not dead."
Yuuji grabs his hand. "Not yet."
"You won't." Sukuna mutters.
Yuuji ignores him. "Let's get married in the Spring."
Sukuna blinks at him. "I was thinking that too."
He's being honest.
Yuuji pulls Sukuns close. He wants a kiss since the asshole doesn't have a ring for him. "Kiss me."
Sukuna does. He kisses his human in all the best ways. With softness, with want and with some annoyance when Yuuji ruins the moment with words.
"You love me." He whispers against his lips.
Sukuna grabs a handful of Yuuji's ass with both hands. "In a non-human way."
