It's warm. Yuuji feels warm all over. Despite how little fabric he is wearing, he isn't cold. He knows he should feel more on edge, but it's like something is missing, like there's something he should be remembering but he can't. All he knows is that his limbs are relaxed, and there's an itch in his tummy that won't go away. It's starting to bother him.
“-ji? Yuuji?” His mother's soft voice brings him back from his stupor, and he's suddenly made aware of what he was missing. He's still sitting at the table, across from his uncle Sukuna, who's eyeing him like he just did something wrong. His uncle who he just met a few weeks ago, his rich uncle that his mother keeps inviting over and making Yuuji behave in front of him.
“I-i sorry! I was-” A shiver runs down his back, words failing him as he flushes hotter under his uncle's stare.
They were recently introduced, his dad never talked about his twin brother, and Yuuji thinks he wasn't very happy when uncle Sukuna walked in their house along with his mom.
‘Look who I just met’, Kaori had said back then cheerily, like it was an expected visit from a long time ago, but Jin had gone completely frozen, as if he couldn't believe what was happening.
Usually, Yuuji didn't shy away from meeting new people, even less family, but uncle Sukuna was different. His stare was too heavy, fixed on Yuuji like he could see through his very flesh and bones, reeking down his body in a way that made him squirm in place.
“I think Yuuji has had too much to eat. Are you feeling sleepy, baby?” Kaori presses her hand to Yuuji’s forehead and smiles just like when he was a little kid and had fallen from the seesaw, like she was sorry for pushing too hard, for letting him get hurt.
Yuuji tries to move away, in typical teenage fashion, shying away from his mother's coddling, but his head doesn't move like he wants. He feels heavy, too heavy, the itch in his tummy is now a constant scratch, it's getting annoying.
“Let's get you to bed.” She says, standing up and pulling Yuuji with her. He's gotten heavier, taller than his mom, but a steady hand keeps him upright, large fingers closing around his arms.
“What do you say when someone helps you out, Yuuji?” His mother presses, like she’s lecturing the five years old version of him, and something hot and heavy spreads inside Yuuji’s chest.
“T-thank you, s-sir.” He mumbles, eyeing his uncle from the corner of his eye, a sly smile twitching at the corner of his lips.
“Oh, no need to be so formal, sweetheart.” Kaori chides, caressing Yuuji’s cheeks that have gone from warm to feverishly hot.
“I-I… It feels-” Yuuji bites his lips, tries to calm his drumming heart that's suddenly too loud in his head. He feels hot all over, like the flames growing inside his stomach have now engulfed his whole body.
“I know, I know, baby. Uncle Sukuna is gonna take care of you now, okay?” Kaori smiles, but Yuuji doesn't know what she's saying, he can only hear his own heartbeat and feel his uncle's glacial fingers against his skin. It feels good.
“Ye-yeah.” He slurs, feeling his center of gravity turning over when his uncle picks him up and carries him upstairs. The house is turning upside down and his mother's voice is far far away.
He's being gently laid down on his own bed, the sheets are cool against his naked thighs and midriff, but the lace of his tiny skirt and bralette that he's wearing is starting to become uncomfortable, itchy.
“Isn't he so cute?” Kaori sits beside Yuuji in the bed, cradling his head in her lap while her hands caress his arms and neck, slowly massaging his shoulders, easing the tension as Yuuji becomes desperate. His skin feels too hot, clammy, his muscles twitch and he doesn't know if he wants to crawl out of himself or hide away curled up. His stomach feels empty, an absence that throbs and hurts.
“Cute is not gonna be enough to be my spouse.” Sukuna's voice is crude, still filled with the same disdain with which he greeted Yuuji for the first time. It makes him unconsciously shy away, but before he can curl on himself, a cold hand closes around his ankle, pulling him back and spreading his legs open.
He whimpers, pulled between shame at the position and relief from being touched.
“Oh, that's because you don't know just how special my Yuuji is.”
Their touch becomes too much after a while, and Yuuji bucks his hips, tries to get away from the hands groping his thighs and legs, and his mother's touch massaging his arms and shoulders.
“Why don't we show your uncle, uhm Yuuji? Do you want to?”
Yuuji whimpers and tries to close his legs once again, seeking some friction for his throbbing dick between his own legs, but Sukuna keeps them open.
“Ngh-hu-hurts!” He shouts, reaching for something, someone, anything that would make the heat go away. Kaori intertwines their fingers and laughs, the sound of her voice echoing in the silence of an empty house.
She flips Yuuji’s tiny skirt up and her fingers slide inside his panties, closing around his length. Yuuji wails like he's been suddenly electrocuted, the pleasure sending sparks all over his body.
“Shhh. Be good for us, baby. Show your uncle how good you can be.” She pumps him a few times until Yuuji’s is bucking his hips into her, chasing more of the friction. He feels right on the edge of cumming but can't reach it, Kaori letting go of his dick every time Yuuji’s body tightens up in anticipation.
Something cold drips down his puckered hole suddenly and he whines pitifully, his dick twitching, soiling the lace of his panties with precum. A hand comes to his hip and presses him down back onto the mattress as Kaori's fingers spread the lube around his entrance.
Something somewhere far away in Yuuji’s heat riddled brain screams to get away, but he doesn't know why he should listen. The touch feels good, and he presses against the fingertips tapping at his hole, welcoming them in instead of pulling away.
“So eager. Always ready to please.” Kaori murmurs, working her way slowly inside her son, curls her fingers forward with expertise.
“More, mo-mom-re.” A blur of words leave Yuuji’s mouth as he sways his hips back, trying to fuck himself on the fingers prodding around his walls. The pleasure comes crashing down like cold water on his scalding skin, and he wants more, he needs more.
“She's such a good little whore, isn't she?” Sukuna laughs, his hand holding Yuuji’s waist, pressing his fingertips against the flushed skin and watching it bloom after. “Learned that from you.”
Kaori laughs again, lightly, and presses against Yuuji’s prostate to hear him sing, loud and needy, wetting himself further.
“He needs you now, Sukuna.” She urges, fucking her fingers in and out of her son, his dick leaking another bead of precome.
“Please, please, please.” Yuuji moans, unsure of what he's asking for, only wanting to reach a high that's almost within his fingertips but keeps eluding him. He misses the sound of a belt unbuckling, crying loudly when Kaori's fingers leave his hole.
“Such a greedy cunt.” Sukuna growls, yanking Yuuji down the bed, his ass flush against his hips. His throbbing cock slides back and forth along Yuuji’s perineum and his hole, driving him up the walls.
“Please.” He cries one more time, clear tears running down his cheeks when he meets his uncle's eyes, hovering over him, a smile that's full of teeth.
Yuuji whines as Sukuna bends his knees up to his chest and fucks inside him just like that in a harsh thrust.
His uncle fucks him rough and purposefully, like he's trying to reach something within Yuuji’s body, carve a place for himself inside. It feels like heaven, even the pain from the stretch is enough to pull Yuuji from his discomfort and launch him into extasis. That's where the itch he couldn't reach is, where his uncle's cock comes up deep inside him.
Sukuna grins, a snarl stretching his mouth wide. “Fuck, so tight, so fucking wet. A pussy made just for me, isn't it?”
His uncle's words fly over Yuuji’s head, choking on his own moans as he tries to ask for more, faster, rougher. He's almost there, desperate to come and release the pressure in his gut. He sobs harder when Kaori's hand caresses his forehead, smiling down at him.
“He was meant to be.” She whispers.
“Take it like the good slut you are.” Sukuna's thrusts grow rougher, pulling Yuuji back to meet every snap of his hips. “That's a good girl,” he praises, condescending, voice filled with contempt.
Yuuji falls right over the edge, wails and cums, hushed by Kaori. His whole body spasms and crashes with pleasure, the itch finally subsiding. Soon he's sobbing quietly as Sukuna uses him like a fleshlight, fucking him into overstimulation until he spills deep inside him, filling Yuuji full of his cum.
Kaori's hand comes to rub at his belly and Sukuna twitches inside.
“See? So special.” She coos. Yuuji’s too out of it to make sense of any of it, still clenching around his uncle's length, his body spamming with aftershocks of bliss, like he doesn't ever wanna let go. The heat is still licking at his skin, muted flames waiting to be put out completely before they rise again.
“A perfect whore is what she is.” Sukuna mocks, rocking back and forth slowly inside Yuuji, enjoying the heat encased around his cock.
Yuuji whines brokenly, trying to meet the rhythm, asking for more silently.
Kaori looks up at Sukuna with a chilling grin that stretches her mouth wide. “And isn't that what you asked for?”
“A ‘wife’ is what I said.” Sukuna growls, folding Yuuji in half as he seates his length as deep as he can go inside his nephew again, with a triumphant gesture of his own.
