It’s mid-morning when Yuuji finally drags himself out of bed to get ready for the day. The afternoon will likely be spent training, and he hopes to spend the evening relaxing with Fushiguro and Kugisaki.
Yuuji yawns, rubbing his neck while making his way to the bathroom. He feels vaguely aware of the skin on his palm pulling open, but it doesn’t quite register until teeth sink into his flesh. Yuuji immediately pulls his hand away, a strangled noise of pain escaping past his clenched teeth as his skin is torn away in the process.
“What the hell, Sukuna?!” Yuuji hisses, palm in front of his face, seething glare fixed on Sukuna’s bloody grin. He keeps his other hand over the wound, blooding oozing through his fingers, the pain throbbing in time with his heartbeat.
“I'm hungry,” Sukuna purrs, “And you happen to taste absolutely divine.”
The deep, sultry tone makes Yuuji's face heat up and his insides twist in myriad of emotions. "Damn curse," he mutters, moving to the mirror above the sink to examine the wound.
He winces at the sight. The bite is deep, blood smeared and still oozing down his collarbone. His shirt is ruined and Yuuji resigns himself to just tearing it off and pressing it against the injury. He sucks in a hissing breath as the fabric rubs against his marred skin before letting it out in heavy sigh.
Once he’s sure the bleeding has stopped, he turns on the water and carefully peels away the shirt, wincing as he does so. It’s a nasty looking wound, likely to leave behind an equally nasty scar. He tears away what little clean fabric is left and dampens it to clean the injury better.
Do you want a taste? Sukuna’s voice suddenly cuts in.
“What?” Yuuji balks, nearly dropping the cloth on the floor.
“Do you want a taste?” Sukuna asks again, this time via a mouth on Yuuji’s cheek.
Yuuji huffs, glaring at the reflection of the red eye watching him. “No, fuck off.”
Sukuna hums, giving him an amused look before receding back to his domain, leaving Yuuji’s cheek untouched. Yuuji frowns, brows furrowed, before shaking his head. He sighs and reaches for the bandages, only to find himself being tugged away into darkness.
He falls into Sukuna’s domain, landing in the water on his back with a grunt of pain. He groans, sits up, and glares at the curse lounging on his throne on skulls who stares down at him with a smirk. Yuuji bares his teeth before standing up, a slew of insults ready to fly out of his mouth. But everything is cut short when Sukuna suddenly stands in front of him and grabs his throat.
“What—” is the only thing Yuuji manages to get out before Sukuna presses his lips against his own in a mockery of a kiss. His mouth already open, it’s easy for Sukuna to slip his tongue in. At least, that’s what Yuuji initially thought, but he quickly realizes it’s a small chunk of meat. Raw meat. Fresh and bloody.
Sukuna pulls away and clamps a hand over Yuuji’s mouth. “Swallow it.”
Yuuji doesn’t want to, in fact, he thinks he might throw up at the mere thought. But the piece meat just sitting on his tongue, there’s something he quickly finds himself unable to deny. It tastes good. Savory, juicy, delicious…divine.
Yuuji swallows.
Removing his hand from Yuuji’s face, Sukuna asks, “Taste good?”
Yuuji glares, wiping his mouth. “What was it?”
“A piece of me.”
Yuuji pauses. “You—what?”
“It was a piece of my flesh,” Sukuna says and grips Yuuji’s chin, a sinful grin playing at his lips. “You liked it, didn’t you? You liked the taste of me. Do you want more?”
Yuuji wants to recoil, push him away, try and get a punch in before Sukuna slices him into ribbons. He wants to stick his fingers in the back of his throat and throw it all up. He wants to deny Sukuna’s insinuation of having enjoyed it. He wants to do all that, and yet—
“Yes.”
Yuuji wants more, craves it, desires it. He shouldn’t, he knows he shouldn’t. This is all some trick, a nasty game that Sukuna has manipulated to his favor. It has to be. But Yuuji’s already trapped, and the only thing on his mind is how much he wants to bite into Sukuna’s flesh and eat.
Sukuna’s smile is cruel but indulgent as his claw cuts into Yuuji’s cheek, drawing blood. He pulls him closer, and Yuuji shivers, noting the sting of Sukuna’s hot tongue as he licks it away. Then, moving to his ear, Sukuna whispers, “Shall we devour each other then?”
Devour. Yes, he wants to devour him, all of him. Suck on the marrow of his bones and lick the blood off his fingers. These are thoughts that should make his stomach churn but instead just make his mouth water. This is bad. This is bad. Something is wrong but he can’t stop. He’s starving.
Yuuji bites into Sukuna’s neck, intent on ripping his throat out, right as Sukuna carves into his chest and tears his heart out for the second time. He wakes up on the bathroom floor with Sukuna’s laughter reverberating in his ribs.
He groans as he stands up, wincing as the movement pulls at the wound on his neck. Blood welling up all over again, and Yuuji watches for a moment as it starts to ooze down his collarbone again.
His mind feels lost, far away, as he wonders where Sukuna carved out that piece of his flesh. His arm? Maybe his thigh? Did he manifest a knife to do it, or did he just use his claws? And then, more importantly, why? Why?
Yuuji’s fingers move to his lips, the tangy iron taste of Sukuna’s blood still lingering in his mouth along with the feeling of his lips pressed against his. There’s a deep, hungry ache in his stomach that demands more. More, more, more.
Don’t worry, Sukuna whispers. There will be more soon. I promise.
