(✨TBC✨)
(I guess Sukuna got the last word this time… But Yuuji got what he wanted, so who won, really?)
(Sorry this took so long to update ☹️ I'm in a bit of a writer's block and even reading my own writing has been hard, but I think finally posting this here is a good sign ☺️)

“Good,” Sukuna says - and leaves to lock himself in the bathroom for the next five minutes.

“If you want there to be a chance in hell that I’ll fuck you,” he says, his voice low enough to almost be a whisper, “you will never make me do this shit in this house again.”
Yuuji’s dazed eyes look a little more awake, and he nods weakly.

He stands up before Yuuji can crawl back into his lap and looks down on the disheveled boy and the wet spot on his shorts.
Sukuna puts a hand on the backrest of the couch and leans in until their faces are almost touching.
comment in response to
post
Yuuji clings tighter to him, unwilling to get off his lap, but Sukuna gave him what he wanted and now he needs to let go, so he pries the brat’s hands off him and pushes him onto the couch cushions.
comment in response to
post
When Yuuji finally breaks the kiss and collapses against him, Sukuna carefully frees his finger from his nephew’s ass and nudges him off his shoulder.
“There,” Sukuna hisses. “Now get that shower - as soon as I’m done washing my fucking hands.”
comment in response to

Sukuna’s breath is high in his chest, his cock throbbing and leaking, but miraculously he hasn’t made a mess of his pants.
Yuuji is a mess, though, panting through his nose and making jerky little thrusts until he’s spent, having come in his pants like the horny teenager he is.
comment in response to

The bite fucking hurts, so Sukuna lets Yuuji’s hip go and grabs a handful of his hair, pulls him back and yanks him into a rough kiss.
Yuuji whines into his mouth, slowly rolling his hips into Sukuna’s lap as he rides out the high, clinging to his shoulders as if he’d collapse otherwise.

Yuuji 𝘸𝘩𝘪𝘮𝘱𝘦𝘳𝘴. He digs his teeth deeper into Sukuna’s shoulder, humps his hard cock frantically, and goes completely still. He whimpers again, his hips bucking against Sukuna in time with the thrusts of his finger, and shudders through the orgasm with a broken groan that turns into a whine.
comment in response to

“Good,” Sukuna whispers and works his finger faster inside the tight little hole. “You have to come.” He pulls almost all the way out and thrusts back inside. “Come on, brat,” he hisses into Yuuji’s hair. “Come on - come for Daddy.”
comment in response to
post
“Don’t stop,” Sukuna breathes into his ear. “Come on, baby.”
He pulls his finger halfway out and slides it back inside to the sound of another muted moan. The aborted little thrusts turn longer again - rougher, like he’s truly chasing to finish.
comment in response to
post
jerking motions that really show how fucking desperate he is for it.
Needy, horny little brat.
Sukuna grabs his hip hard and shoves his finger inside to the last knuckle.
Yuuji bites his shoulder with a muffled moan, his hips stuttering.
comment in response to
post
Yuuji gasps and digs his nails into Sukuna’s shoulders. He pushes back, taking more of the finger inside, and moans with his lips pressed against Sukuna’s throat. His hips don’t stop moving, his dick rubbing against Sukuna’s length with quick,-
comment in response to
post
Letting the brat use him to get off is one thing, massaging his asshole another, but Sukuna is fucking dying to feel how tight he is.
When Yuuji leans against his shoulder with a shuddering exhale, Sukuna nips at his neck and sinks the finger inside of his trembling body.
comment in response to
post
He circles the tight muscle with haste, pressing down harder when Yuuji pushes back against his finger.
Fuck. Sukuna shouldn’t touch him. Not like this. Not 𝘢𝘵 𝘢𝘭𝘭.
comment in response to
post
He drags them along the crack to press one against Yuuji’s hole, and the kid mewls against his neck.
“𝘖𝘫𝘪𝘴𝘢𝘯.”
“You have to come, baby boy,” Sukuna whispers against slack lips.
comment in response to
post
The pressure and Yuuji’s increasingly erratic humping make his cock feel about ready to burst out of his jeans. He needs to make the brat finish fast so without further wait or warning, he grabs the back of Yuuji’s shorts and tugs them down to slip his slick fingers inside.
comment in response to
post
Yuuji whimpers and grinds against him faster, sucking on Sukuna’s fingers hard before opening his mouth and licking them until spit starts running down his hand.
“Good boy,” Sukuna whispers, his voice barely a breath.
comment in response to
post
“You needy little slut.” He curls his fingers down on Yuuji’s tongue, forcing his mouth open, and saliva runs down his nephew’s chin. “There you go. Make them really wet, baby.”
comment in response to
post
The brat fucking sucks on them, his tongue stroking them both while the roll of his hips turns more desperate.
“Look at you,” Sukuna whispers, trying his best to ignore the tight strain against his cock and the extra pressure that threatens to make him come before Yuuji does.
comment in response to
post
He touches Yuuji’s bottom lip with his index finger.
His eyes flicker open and he looks just as turned on and dazed as before, so Sukuna doesn’t hesitate to press two fingers to his tongue and slowly slide them deeper into his mouth.
Yuuji moans again, the sound vibrating against Sukuna’s fingers.
comment in response to
post
He doesn’t move fast, but it’s definitely humping. Yuuji’s breath is quick and short, stuttering at the end of each firm grind, and his mouth hangs open right in front of Sukuna’s. Inviting.
Sukuna considers kissing him, but when a low, trembling moan leaves his nephew’s lips he gets a better idea.
comment in response to
post
Yuuji nods, his breath shuddering out of him. “Yes, Daddy.”
He sinks into Sukuna’s lap, tilting his hips so that their dicks are pressed together firmly. When he starts grinding on Sukuna’s cock again it’s without the carefulness from before.
comment in response to
post
He takes one of Sukuna’s hands and pulls it towards his crotch, but Sukuna doesn’t let him.
“No,” he says quietly, his lips grazing Yuuji’s chin. “If you want this, there’s only one way of getting it - by humping me like a fucking dog until you cream your own pants. Understood?”
comment in response to
post
Yuuji grinds against him again. “But I’m close already.”
Sukuna barely refrains from biting his own lip to keep from saying what he says.
“You can come, and then you have that shower and change. Okay?”
Yuuji nods. “Okay,” he whispers. “Okay. Will you touch me?”
comment in response to
post
“Please, Daddy?” he whispers, and Sukuna once again feels like he should both praise and murder whoever made his nephew like this.
“I’m not taking my cock out on your father’s fucking couch, Yuuji.”
“But—”
“No.”
“I just—”
“𝘕𝘰.”
comment in response to
post
His fingers find the button in Sukuna’s jeans, but that goes so far past fine that he grabs Yuuji’s hands and pushes them back.
“You’re not touching my cock, brat.”
Yuuji whines again, digging his teeth into his bottom lip with a pleading look at Sukuna.
comment in response to
post
He blinks his eyes open, heavy-lidded and dazed with lust. “Don’t stop,” he whispers.
“For fuck’s sake, Yuuji - do you want us to come in our pants right before dinner?”
“I’ll take a shower and change.”
“And me?”
Yuuji grins. “I don’t want you to come unless I get to see it.”
comment in response to
post
Sukuna forces him back by leaning forward and putting his beer on the coffee table. He grabs Yuuji’s jaw and holds him at bay when he sinks back against the couch, making the brat whine in disappointment.
comment in response to
post
He’s rock-hard in his black jeans, straining against the tight denim while Yuuji grinds their dicks together. Little sounds leave him between kisses - kisses that Sukuna started to return at some point without really meaning to - and his movements grow more and more desperate.
comment in response to
post
Sukuna tries to say his name, but Yuuji won’t let him speak at all. His tongue fills Sukuna’s mouth, stroking his own in ways that make sparks light up along his spine.
Whoever taught Yuuji this shit did a good job. Sukuna still kind of wants to kill them, though.
comment in response to
post
“I’ll give you whatever the fuck you want if you get off me right now.”
Yuuji lights up. “You’ll fuck me?”
“𝘕𝘰 - anything but that.”
Yuuji pouts again. “That’s the only thing that would make me stop.”
He winds his arms tighter around Sukuna’s neck and pulls him in.
comment in response to
post
“No - for fuck’s sake, Yuuji, stop it.”
Yuuji pulls back a little, looking pouty and defiant all at once. “I keep giving you what you want,” he says, sounding outright petulant, “and you never give me anything back.”
comment in response to
post
Yuuji grins and grinds, and doesn’t reply. “Don’t bother. All I care about right now is this.”
He rolls his hips, pressing their cocks tight together, and whines behind closed lips.
“Quiet,” Sukuna whispers. “We can’t fucking do this here.”
“But we can somewhere else?”
comment in response to
post
“What’s that supposed to mean?” Sukuna growls.
“It’s not like I always pretend that they are you… but with some it’s really easy to do so since… Well, they remind me of you, I guess.”
“Fucking hell, kid - how many are there?”
comment in response to
post
“Then I’d wonder when you started wanting this - and if they were always stand-ins or if they became that once you tricked yourself into thinking you had a shot with me.”
Yuuji grinds against him again, a little harder this time.
He hums softly. “Maybe a little bit of both?”
comment in response to
post
Sukuna doesn’t know whether to be flattered or put off by how much his nephew wants to be fucked by him.
“Really?” Sukuna says quietly. “You make it sound like they’re nothing but stand-ins for me.”
“What if they were?”
comment in response to
post
“So what? If I won’t fuck you, you’ll take any other cock that’s available?”
“Yeah.”
“You really are a fucking slut.”
“I never said I wasn't,” Yuuji says, almost innocently, but his smile is anything but. “Maybe if you fucked me… that’d be enough.”
comment in response to
post
“You fucking brat,” Sukuna murmurs when Yuuji pulls back.
“Your brat," Yuuji whispers with a smile and kisses him again, working his hips slowly against Sukuna’s lap.
“What about the others?”
Yuuji grins. “If you won’t fuck me one of them will.”
Sukuna’s fingers dig into Yuuji’s hip.
comment in response to
post
“Yes, it can.” Yuuji rolls his hips again. “I want your cock, Daddy,” he whispers - and presses their lips together.
Sukuna sits frozen for a moment, his beer bottle in one hand and Yuuji’s hip in the other, while his nephew licks into his mouth with a low hum.
comment in response to
post
Another roll of Yuuji’s hips forces Sukuna to bite back a groan.
“No,” he growls.
Another grind.
“I know you want to.”
“I don’t. This can never be more than what it has been so far.”
comment in response to
post
“What the fuck, Yuuji.”
He grinds against Sukuna again, and a rush of air leaves his lips.
“𝘖𝘫𝘪𝘴𝘢𝘯.”
“Yuuji - get off me.”
“You’re getting hard.”
“That doesn’t matter. Stop it.”
“Tell me I can come over.”
comment in response to
post
His already hard dick presses against Sukuna’s, making it stir to life, too.
“Fuck,” he breathes. “Yuuji, 𝘯𝘰𝘵 𝘩𝘦𝘳𝘦.”
“Then let me come over sometime. Do what you said you would over the phone.”
“You know that can’t happen.”
“Why? It’s not like you could knock me up.”
comment in response to
post
That’s the routine, yes, but Sukuna’s certain that if Pops is ever going to wake up early it’s now.
“Get the fuck off me.”
Yuuji smiles and a puff of air hits Sukuna’s lips.
“I’d rather get you off,” he whispers - and grinds his hips into Sukuna’s lap.
comment in response to

Yuuji winds his arms around his neck. “No.”
“We’re in the fucking living room.”
“So? You said we have time.”
“Did you forget about your grandfather?” Sukuna hisses.
“He’ll be asleep until Dad wakes him up for dinner, you know that.”
