AU in which Sukuna is neighbours with a bubbly and friendly Yuuji, who's the street's sweetheart. He gets invited for dinner almost everyday and he begrudgingly accepts - even though deep down he likes it. He realizes that Yuuji only invites him and he puffs up like a peacock whenever people complain that the sweet Itadori-san only invites him, a menace to them all, for dinner and not them. Only Sukuna has gotten the pleasure of seeing Yuuji in only trousers or shorts and his usual pink apron when he cooks.
One day, Sukuna attends and he dines with Yuuji like usual. One moment he's on the dining table eating to his heart's content, the next he's tied to the bed and getting his cock ridden, to his shocked pleasure, by a naked Yuuji.
Yuuji's bouncing on his cock like a starved man - drool trailing down his chin and his eyes shining insanely with lust (Sukuna can swear he sees hearts in them). His pink nipples are erect and his cock is slapping against his stomach as he bounces up and down on Sukuna's impressive cock.
"You're so big, Sukuna-san~" Yuuji moaned out, his strong and thick thighs flexing as he works himself up and down that hard cock that has his lubed up cunt spread so wide and is reaching places so deep he could never touch with his fingers. "I should have done this a long- ah! Oh, yes! I should have drugged you sooner and tied you to my bed a long time ago if this is how delicious your cock will be~"
Sukuna tries so hard to stop his hips from moving and thrusting up into Yuuji. He tries so hard to ensure that he isn't enjoying this but that becomes moot when Yuuji lets out a rather loud and slutry moan that goes straight to Sukuna's cock.
Yuuji could only let out a shocked gasp as the cuffs he used to chain Sukuna to the headboard snaps like twigs due to the man's outlandish brute strength, and Yuuji finds himself on his back - looking up into wild red eyes that shine with a terrifying promise.
Sukuna hikes Yuuji's legs onto his shoulders and he folds the man in half. His cock goes in deeper than ever in the position, and Yuuji throws his head back with a loud moan - his eyes going wide. Using his knees and feet to balance himself, as well as placing his hands beside Yuuji's head, caging him, Sukuna starts fucking the coherency out of Yuuji.
Loud screams, squeals and praises for more ring loudly in the room. Sukuna won't be surprised if the other neighbours could hear Yuuji crying out like the cock slut he is. The sound of skin hitting skin and Sukuna's cock drilling into Yuuji's wet channel joins the symphony.
With his cock trapped between his and Sukuna's hard stomachs, and Sukuna pounding his prostate like no tomorrow with well aimed and precise thrusts, Yuuji approaches his orgasm so fast that he doesn't even see it coming. His fingers grip Sukuna's shoulders tight and his nails dig into the flesh when his orgasm is ripped from him so suddenly that he sees white. His cock spurts out thick ropes of cum on their stomachs, painting their skins with white.
But Sukuna isn't done yet. The goth oriented man has finally been given the opportunity to finally fuck the man of his jerk off material as of late. He's finally fucking the street's sweetheart and the man occupying his thoughts 24/7.
Sukuna turns Yuuji around onto his stomach and puts him into a breeding position. His legs spread Yuuji's apart and holds them still, whilst he cages Yuuji with his larger body.
All Yuuji can do is let out those beautiful noises Sukuna has come to love as he claws at the sheets. Sukuna's hands reach for his and the man above him intertwines their fingers together. Yuuji holds those large hands tight as he gets his entire core shaken by Sukuna's cock - tears and drool running down his face.
As he gets his brain fucked out, Yuuji realizes that he has bitten off more he could chew. Or take, in this case.
