wants to see its tongue and teeth, wants to see if it can talk. If it can kiss him like Sukuna does. Sukuna himself is watching Yuuji fight the lips on his stomach half amused half irritated. It wasn’t like that mouth had a mind completely of its own, but Yuuji was messing

around, playing. And although his little whines at his failed attempts annoyed him to a degree, he knew Yuuji was just a kid, he wanted to play. “Yuuji, get away from it, it’s dirty.” Yuuji frowns, an angry pout on his lips. “With what? Spit? I can take it!” Sukuna sighs,

Flicking Yuuji’s forehead and smirking as the boy whimpers and rubs the stinging skin. “No.” “Then what?” “…” “Then it’s not dirty.” “Blood.” Sukuna rolls his eyes as Yuuji gasps, yet instead of being horrified or disgusted the kid’s eyes light up in wonder. “Blood?”

“Does it drink it like water?” Thinking he’ll frighten the boy away with his answer, he nods. “What’s it taste like?” Yuuji sounds way too enthusiastic to be afraid, and Sukuna’s obliviousness to the boy’s excitement about such things only helped grow it. “…Sweet.”

Yuuji looks up at him from under his lashes, eyes narrow and calculating and lips bitten in concentration. He remains silent for a bit, wriggling his small hands as he shifts his weight on Sukuna’s lap. Sukuna lets him mule over it, not pushing but not bashing his thoughts away

either. Sukuna’s eyes wander to his slim waist supported by on of Sukuna’s hands. He looks down at the short legs straddling him, barely able to stretch on one thigh of his. His kimono stretches along small legs, outlining the small, chubby thighs hiding away Yuuji’s treasure.

He’s too focused on tracing Yuuji’s body with his eyes and warming under tan skin to see Yuuji drag his little finger under his canine tooth, wincing softly as he watches a bead of blood roll out. Sukuna Instantly stiffens, smelling the metallic stench on Yuuji’s finger and

dropping on his kimono. Sukuna grunts before his belly mouth opens up, unconsciously drawn to blood, tongue rolling out like a moth to flame. Yuuji instantly perks up, pushing his finger towards the huge tongue coming out for a taste. Sukuna’s hand reaches out to catch his wrist

harshly, holding it in place, but his tongue moves fast still, licking an entire stripe up from Yuuji’s small wrist to his bleeding finger. Sukuna groans at the taste, scowling as Yuuji giggles, the tongue ticklish on his hand. The tongue doesn’t stop, pulls Yuuji’s hand closer

till it wrapped all around his hand, licking it all over, relishing in the taste of the kid’s soft honey skin. Sukuna stiffens with Yuuji on his thigh, laughing and gasping at the way the tongue licked his hand and fingers, teeth biting gently but harsh enough to scare him

Yuuji isn’t scared, of Sukuna? He never was. And it is no different now, even when the tongue moves to lick down Yuuji’s forearm, nip his knuckles nd pushe the fabric of Yuuji’s kimono away from his chest. Yuuji leaning close, curious and amused “Kuna it’s so cute n ticklish!”

“Cute? Watch your tongue, brat.” Yuuji giggles. “No /you/ watch it! Get it?” His laughter echo through the empty halls as he leans down to offer his chest to the mouth, little nipples soft and molten against his chest, reddening by the minute at the belly’s hot breath.

Yuuji squeaky voice alters between quiet whines and sharp giggles, far too cute for the palpable feeling between them, hard with edges and soft as butter like Yuuji’s skin. Sukuna can’t help but wrap his hands around the boy, two hands on his waist lifting him up for the tongue

,one pushing back Yuuji’s spiky hair, taming it down as he pushes his hips up, sitting Yuuji on the base of his erection, too big nd fast growing as he watches Yuuji play with his belly mouth. An endearing and arousing sight. He can’t help but let his tongue slip through fabric

,lifting up sleeves and pushing away past belts to trace wet trails on small, unmarked trembling thighs barely holding the pink haired child up. Yuuji looks up in surprise, blush dusting his cheeks as he hums a shaky question, clutching his kimono tightly. So confused, so pure.

He would add innocent but not when the same little boy perched up on his thigh just got him hard from letting his huge tongue taste his hands and blood, was also now wet on that same thigh, little knees wobbling to close as his wetness leaks a wet patch on Sukuna’s skin

His little cunt drenched and warm as it slipped from under the fabric as he moved, no cloth to keep him covered but Sukuna’s thigh pressing firmly up to him,presence and strength inviting Yuuji to hump him as he holds the back of his thighs between tight hands. He was soaking +

through the fabric, his undergarments thin and sticking to his dripping core, rubbing wetness all over Sukuna’s thigh nd seeping to his knee. Yuuji was leaning away from the tongue, small fists pushing him up as it licks his chest on last time, drooling over his chest like a dog

“Kid—“ Yuuji giggles, ignoring Sukuna as if that tongue was a part of him. He wipes his chest with his hand and huffs, “I’m so wet!” Sukuna holds back a grunt, Yuuji wasn’t even aware of how wet he was down there humping him. Wasn’t aware he’s even doing it, he’d further guess

“Yes you are, now get up and wash yourself. It is gross Yuuji.” “But the tongue is not! He is not gross!” Yuuji bites his lip and pushes himself up to face his belly mouth again, little thighs spread on his lower abdomen instead. Right at the base of his erection.

Sukuna doesn’t bother stopping him as he runs his fingers along the teeth, he threatens to bite him but Yuuji just laughs, squeaky and care free. What Sukuna doesn’t expect is for Yuuji to kiss its lips. Little mouth pressed on wide lips then firmly on the center of the tongue

Sukuna stiffens, hands reaching out to grip the kid’s wrists, holding them tightly he was sure they’d bruise. He breathes heavily, short breaths stunned at the sight of Yuuji pressing kisses from the center to the tip of the tongue, watching him hesitate before peeking his own

tongue out and licking this tip of Sukuna’s belly tongue. Sukuna’s hand springs out to grip the boy’s hair, nostrils flaring, panting as he tilts Yuuji’s head back, ears ringing with the kid’s yelps and scratching nails on his hands. “I just wanted to give it a thank you kiss!”

A thank you kiss? Pecking it and licking the tip is a thank you? He watches the boy’s cheek blood red with embarrassment, knees wobbling as he clings to Sukuna’s arm to stay up. Sukuna grips his hair tighter. “If you want to kiss it thank you for dirtying you brat, show me.”

“Kiss it.” Yuuji looks skeptical, hesitant as Sukuna lowers his head to his tongue, letting him lean his hands on his sides as his belly mouth sneers. Yuuiji was already a mess with the saliva on his torso and neck, thick droplets clinging to his skin as his eyes travel between

Sukuna’s unwavering gaze and the tongue poking his sides as he slides lower towards it. Yuuji gulps and adjusts his position on Sukuna’s firm thigh before leaning down again, kissing the teeth with a trembling hesitation before giggling again, tickled by the tongue sliding down

his torso to his hips, exposing his chest completely as the fabric slides down his body. Yuuji shivers and tuts the tongue as if scolding it, tapping the thin lips before pressing a chaste kiss to the tip. Sukuna’s dick twitches fully clothed, suffocated under Yuuji. A few nips

later Yuuji finds the courage to let his tongue lick the tip, squirming in place as he licks long strips from its side to the tip then gently sucking it into his mouth. He was treating his tongue like he would a sweet or his dick, it has Sukuna stiff with cold air in his lungs

trapped as he watches, mesmerised by the sight of this little boy kissing and slurping on his tongue like he has before on Sukuna’s mouth. He was a mess, the sticky spit was cooling on his skin, making him shiver as his hips move on their own, grinding his small ass on Sukuna’s

hardness, slick pooling at the edge of Sukuna’s trousers, forming a wet spot on the waistband. Yuuji was moaning too, oblivious to Sukuna’s deep strained breathes of air and his tightening hold on the boy’s limbs, keeping him in place against him. Sukuna looks on with wide eyes
