Work Text:
Itadori Sukuna’s favorite meal is one hundred and seventy-three centimeters of soft skin.
From the first time he held her, he knew she was divine. His older brother’s bundle of joy, swaddled in a blanket much too big for her, babbling loudly at him as she tried to wrap her chubby hand around his finger. Her warm brown eyes had looked up at him, pure innocence and wonder behind them. She was perfection personified.
Sukuna knew he had to have her.
So he took her.
He looks forward to the end of his work day, counting down the minutes until he can meet her in the teacher’s lounge, cock straining against his pants, red and aching, as he thinks about shoving his tongue between her legs, kissing her warm skin and lapping up her slick like he needs it to breathe.
His niece Yuuji is the sweetest thing he’s ever tasted.
She tastes sweetest when she acts like she doesn’t want it.
But, Sukuna is a patient man. He’s trained her from the moment he got full custody. Didn’t even let Wasuke settle into his grave before he started roaming her body, fingers slipping under her waistband so he could show her how to come over and over again. Telling her how she should crook her fingers, angle them just right to hit that perfect spot inside of her that makes her soak the sheets. How to caress her body the exact same way he does, how to make her breath hitch, have her face flush, begging for more.
He’s created the ideal little doll for himself. He thanks his family for that.
He loves how her eyes widen when he pulls her onto his lap in his classroom, hardness pressing against her as he grades papers and scolds her about being out of dress code. She mumbles that she’s not a little kid anymore, that all he does is embarrass her, but she never gets up. He just rocks against her, hand splayed across the plush thighs, fingers dipping between them, but never actually giving her what she wants.
He ignores her until she’s a whimpering, babbling mess, crying and sniffling as she pushes back onto him, urging him to hurry up, to bend her over his desk and please fuck her.
And because he’s such a good uncle, he gives his precious niece whatever she wants. Even when she tells him to stop, pleading as he pounds into her tight heat from behind. Even as she holds onto the edge of the desk, crying out that it hurts, uncle, that he’s too big, that he’s going to split her open.
If Yuuji didn’t want it, she wouldn’t get as wet as she does. Wouldn’t grip him like she never wants him to let go. Wouldn’t beg him to breed her, fill her up like the little slut she is.
So, he makes sure to always take care of her. Makes sure that she’s always satisfied, toes curling as he gets her over the edge, thanking him, his name leaving her lips like prayer. He always has her sit on his face after he comes inside of her, cleaning her up so he doesn’t have to bother buying a morning-after pill, sticking his tongue all the way inside of her until he feels his cum drip onto his tongue.
The tongue on his face isn’t the only one that looks forward to tasting her, however.
After all, he never said he wasn’t selfish.
“Sukuna, what the fuck—”
“Oh, be quiet,” he snaps, tossing her underwear to the floor as the grip on her hips tightens. She turns to look at them, staring at the wet spot in the middle of the cotton. He pushes her down further onto his stomach. “You’re acting as if you don’t like this.”
Yuuji huffs, tears falling from her eyes. They spill down her face until they land on his skin, fists hitting Sukuna’s hands in a futile attempt to free herself. “I don’t—”
“Really?” He raises an eyebrow, pinning her fists behind her back, fingers digging into the flush skin of her wrists as she struggles. “You’re not trying to get up.”
“You’re not letting—”
The tongue on his stomach reaches out between the buttons of his shirt, licking a broad stripe through her cunt, collecting the slick she keeps pretending hasn’t been pooling from the second he grabbed her.
“Then why are you dripping wet for me, darling?”
More tears fall from her eyes as she scowls at him, huffing as she tries to wriggle out of his grip. She bites her bottom lip, canine working it until it gives. Red pools where she sunk her teeth in, trickling out from the corner of her mouth.
“Just be a good girl for me, will you?” His free hand reaches up to roughly grab her chin so she can’t look away. “Uncle will take care of you. I always do.”
Yuuji flicks her tongue out to smear blood and saliva across her bottom lip. She mumbles something about the tongue on his stomach, but he’s not listening. He watches how her lip glistens, cock twitching in his slacks.
Her face flushes as she makes eye contact, squirming in his lap with small, desperate shifts of her hips. All the movement does is make that tongue sink further into her warmth, spreading her folds.
“Sukuna please—”
He tilts his head. “Please what, sweetheart?”
Yuuji whines as the tip of his tongue makes its way to her entrance, circling once before starting to lazily thrust in and out her, twisting in on itself as it stretches her open.
“Please stop—” She gasps as the tongue curls up. “Stop teasing me.”
Sukuna’s smirk splits into something that’s all teeth. "All you had to do was ask.”
The buttons on his shirt pop open as his tongue twists into itself tighter, allowing Yuuji to fully impale herself on it, snaking its way into her drenched insides. She moans as it bottoms out inside of her.
He hisses through his teeth as he stares at her, cock straining uncomfortably in his slacks. But he can’t make her get up. Not when she looks this beautiful. Tears run down her cheeks as she lets out little gasps, hips moving quick and impatient. Sukuna’s tongue meets her movements, her arms going pliant as she decides to stop fighting, chasing the pleasure she’s been craving.
Yuuji’s movements get more desperate, breasts bouncing under her shirt as she fucks herself on his tongue, when she suddenly stops. Her back arches as she tilts her head back, pink hair cascading over her shoulders, staring at the ceiling, mouth open in a silent scream as she spills all over his stomach. His hand reaches back up to cradle her cheek, tilting her face down to look at him as he presses soothing circles into her damp skin.
“Such a good girl,” Sukuna murmurs. She hums when his lips meet her forehead, pressing a soft kiss on her skin. “Always such a good girl for me.”
Sukuna lets go of her wrists and places them on her hips, firm and possessive, as he scoots further down the couch cushions.
“Come up here, princess.” He pats his collarbones as he looks up at her, head flat against the sofa. “Want to taste you everywhere.”
Yuuji meets his gaze, eyes half-lidded, and nods slowly, thighs shaking as she sits up on her knees. She inches forward until she’s hovering over Sukuna’s face, placing her palms on either side of his head as she plans how to sit.
Sukuna sees the soft smile on her face, the way her skin is flushed the same color as her hair, and decides he’s done waiting. His hands come up to cup her ass, kneading her skin, spreading her open. He pulls her down, forcing her dripping cunt down and onto his mouth, clit landing on the tip of his nose.
He inhales deeply, her scent surrounding him, and starts lapping at her like a dog, tongue moving up in down in frantic strokes. He tilts his chin up so he can circle her clit, once, twice, lips pursing around the tender nub and sucking.
“Ah— Kuna—” Yuuji leans forward as she grinds down onto him. She starts shaking and Sukuna is sure she’s going to come again when she quickly sits up on her knees. “H—hold on.”
He groans at the loss of contact, feeling her slick drip down onto his face. He opens his eyes, sucking in a breath as he watches her thighs tremble.
Yuuji carefully turns around, hands grabbing at every part of him as she sinks back down, facing his legs. Her hands settle on his collarbones as she starts moving her hips again, the new angle letting her rub against his nose better if her soft noises are any indication.
She lets out a drawn-out moan as she drags her pussy against his nose. Her hands slide up from his collarbones to tentatively rest on his neck, fingers twitching like she’s not sure if she should fully make contact. Yuuji carefully wraps her fingers around his throat as she presses down, continuing to fuck her uncle’s face.
She’s close now, whimpers turning into whines as the desperate sounds leave her throat as she hungrily chases the friction he can provide her. Her grip tightening around his neck, palms closing off his airway as her fingers press into the sides of his throat.
Sukuna’s vision starts to get white and staticky at the edges, and that only spurs him on further, cock twitching angrily in his pants as her thighs shudder around his head. His tongue moves eagerly as it slurps up her slick, tasting every inch of her heat.
When she starts keening, trying to lift up and off of him, he tightens his grip on her hips, fingers leaving indents on her skin so she can’t run away. Yuuji squeezes her hands, practically crushing his windpipe as she falls over the edge. Sukuna’s stomach coils as her cum slides down his chin and neck, pooling into the hollows of his collarbones and soaking the cushions under him.
His fingers splay across her ass as her spreads her open even more, tongue tracing broad strokes through her cunt. The sounds are obscene, wet slurps coming from the heat between her legs as he desperately tries to make sure not a single drop gets wasted.
“Fuck—” The word barely leaves her lips before she starts convulsing, folding in on herself as pleasure shoots through her entire body. The sensation makes her boneless, hands loosening around his neck.
“That’s right, baby,” he croaks out from under her, voice shot from the lack of air, words barely distinguishable as they get muffled by her skin. “Keep coming for me. I’ll clean you up.”
Yuuji lets out a pained noise. “Let me— let me get up—”
Sukuna tries to shake his head and grips her ass harder, bruising her skin as he pulls her down harshly, wanting her to suffocate him. His stomach tightens, heat and want and hunger knotting together as he tastes her over and over, honey-sweet and addicting.
She lets out a high-pitched whimper as he continues his relentless movements, nails dragging across his chest as it becomes too much. That does it for him—he lets out a low, guttural noise against her cunt as he comes in his slacks, cock twitching helplessly as the tight fabric of his pants sticks to his skin.
“Oh my god—”
A sob escapes Yuuji as she comes again, begging for mercy. More tears hit Sukuna’s chest as her arms give out, finally allowing Sukuna to get adequate air as her panting breaths ghost over his ruined pants. She lets out a shuddering exhale as her elbows dig into his sides, trying to get up. She rolls off his face and lands on the couch beside him with a dull thud.
“Ijichi-san is going to be so mad.” The words are barely audible as she tries to catch her breath, staring at the damp fabric surrounding Sukuna’s head.
Sukuna laughs at he sits up, clothes ruined, hair wet, face glistening with all of Yuuji’s juices. He helps her sit up fully and wraps an arm around her waist, pulling her toward him, settling her onto his lap as he scoots against the arm of the sofa.
“He’ll survive.” He grabs her chin and presses a kiss to her lips, soft and gentle. A full body shiver goes through her as he deepens the kiss. She kisses him back with the same intensity, hands coming up to thread through his hair as she tilts her head.
She needs to know why she makes him crazy.
Yuuji whimpers as Sukuna shoves his tongue deeper into her mouth, making sure she never forgets what she tastes like. He pulls back and presses their foreheads together, staring into those warm brown eyes that he’s been smitten with since day one.
“Thank you, baby, you taste divine.”
He’ll never be able to get enough.
