there this one twin fic where yuuji calls sukuna "suki-nii" which means like or love, absolutely demolishes me everytime i think back on it.

it isnt how it was like the first time sukuna forced him. ever since then, yuuji was different, chasing that same fear.

and then sukuna learned domain expansion...

and sukuna ignoring him. yuuji loves getting brutalized by his brother, loves to get raped by him.

but its not enough because its never truly rape because yuuji loves it no matter how brutal sukuna gets.

when sukuna fucks his brother, he bites his nape to hold him still. like an animal.

snarls into his skin and rages when he tries to move.

sukuna loves it when yuuji is docile under him, accepts everything he gives.

they make a game out of it, yuuji pretending to say no

he knows someone is peeking at the crack of the door. whether its choso this time or jin, or both of them, doesn't matter, because they'll never be able to touch him the way he does. he'll kill them.

yuuji was born into this world for the sole purpose of being his. his one true soulmate.

knowing he can keep it up bc his boy is used to overstimulation. slaps the wet pussy a few times just to see the slick splash everywhere.

its an obscene sight. yuuji's legs spread wide and tense, his feet pointed upward, and toes culred, hips still humping at the air.

"tickle fight! tickle fight!" his eyes roll back from pleasure, mouth opening wide and tongue sticking out like his uncle thought him to do when he feels really good.

the small boy covulses on top of his uncle, squirting piss everywhere.

sukuna fingers the boy through it,

when his uncle bucks into him, almost throwing him off if not for the tight grip he has around his waist.

"my pussy is leaking so much love juices, please more! i wanna piss more!"

sukuna reaches to finger at the pink swollen nub, just a touch is enough to send the boy screaming in glee

his uncle has long ago explained to him what it was. a different type of piss that means he loves his uncle very much, and uncle loves him back.

he teaches him of other fun stuff too, other fun words he was instructed to say.

"i love ridding your big cock uncle" yuuji giggles-

yuuji does, slipping off the white baby boy shorts to reveal his bare rosey pussy to his uncle.

the boy pants and whines, loving the game even more. the throbing is stronger now in his pussy, piss trickles down his thigh and wetting his uncle's pants.

he would unintentionally ride and hump at his uncle's bulge, "horsey go faster!" sweating and having the time of his life not understanding the tingly good feeling in his pussy.

unckuna laughing at the innocent dirty words "what a good cowgirl you are, comeon - take of your shorts for me"

he catches himself grinning at marks sometimes, especially when its visible. he cant help but rub and press on it and make yuuji squirm and try not to flinch away from the pain.

he kisses it better and apologizes, knowing he'll do it again later and they both know it.

sukuna still bites when they are awake ofcourse but he takes care not to be too rough with yuuji.

he feels a bit guilty about how painful it looks and probably feels but more because of how derangedly happy the wounds make him.
