"Tell me, child, do you want more?"
"M-more?" Sukuna's already balls deep inside Fushiguro, his fat cock splitting him open and making the tight ring of muscle visibly struggle to accommodate him. So the boy's question is kind of valid.
"Oh yeah, more. Don't tell me I've fucked you so good you forgot the meaning of the words already, Fushiguro." Sukuna still mocks him anyway, a large grin on his devilish handsome face (Itadori's but still, his black ink all over this body makes all the difference).
"It's impossible, it's already too...too much" He loves to hear him struggle to speak. Loves loves loves how pliant and cute he becomes beneath his hands. "And there's so much...stuff inside"
Stuff, Sukuna laughs low. Can't even say out loud what it is, huh?
"That's so easy to resolve, silly."
Sukuna removes himself out of the velvety interior with a swift move, despite the tightness. Two nice thoughts come to his mind. One, letting the boy's ass close and keeping everything inside forever (maybe some other day). Two, fucking him enough times so his hole isn't tight like that anymore (do it, do it, do it, even if the brat doesn't want to his brain screams).
He uses both hands to keep the hole open, not letting Fushiguro's tight ass close again.
It doesn't take long, the boy's right, he is very full. Sukuna could barely move inside before.
Soon, his own cum starts to drip out of the hole, leaving a lovely trail on Fushiguro's perineum and thighs. Too bad it doesn't even have a nice contrast since the boy's so pale. But it's beautiful to see anyway. And to think he's been holding that much load inside... Just makes Sukuna wants to pump him full even more now.
"As much as I hate to waste my own seed, it's for a good cause." He tells himself more than he tells the boy.
He doesn't give him time to rest either. As soon as enough cum has leaked he shoves his cock back into his personal cocksleeve without as much as a warning.
"Fuck, fuck, fuck, motherfucker," Fushiguro sounds mouth-watering. The perfect balanced between ruined and pissed off, and what's even better is that he actually thrusts back on Sukuna's cock instead of pushing away. The boy likes the stretch. Likes the pain. Which is good, because for the next step if he didn't...well, if he didn't Sukuna would have to shut up his screams somehow, because he would fuck him anyway.
"Now, where were we?" He smiles by the boy's flushed ear and licks it sinfully as he speaks. "Right, I was asking if you wanted more, Fushiguro, and I still expect an answer."
The boy's squirming to get away from his tongue but Sukuna just grows another pair of arms and restrains him. Sometimes he thinks this boy isn't that bright after all, he should know by now there's no escape.
Or maybe... He doesn't even really want to escape. It's all for show. All for some stupid pride. Too stubborn to give in. So he can sleep with a clear conscience at night and think that he tried to, but oh well. The thought is absolutely hilarious.
And Sukuna can't wait to ruin it. The boy wants to have a clear conscience, but Sukuna won't fucking let him. He won't take what's his, even if he could, even if it's simple food chain dynamics.
"I won't do it. Won't even fucking move until you tell me you want it." He tries to sound serious, tries to sound as if he's not having the time of his like right now but it's too damn hard. Specially when Fushiguro panics and clenches tight on Sukuna's cock filling him. Pathetic. Delicious.
Sukuna keeps his promise though, and doesn't move a muscle. He lets Fushiguro go and the boy could very well just leave but of course he won't. Of course he's as addicted as Sukuna is to this right now. Even if the boy has literally no fucking idea of what he's dealing with, even knowing he could get hurt, he could have so much horrible stuff happen to him, even so he still chooses to stay and wait to see.
Such an interesting child. As expected, Sukuna chose well.
"I want." Sukuna can feel Fushiguro's pride being wounded just by uttering two little words.
It's not enough though.
"You want. What?" There's one more magic little word missing, and Sukuna's been dying to hear the boy say it. More, more, more, tell me you need me to ruin you even more.
"Everything."
Oh. If he was moving he might've nutted on the spot. Fushiguro always does this, doesn't him? Surprise him with his desires.
Sukuna comes close to the shell of Fushiguro's ear again, still wet from his licks before, "Never imagined you'd behave so well. Kinda always assumed I'd have to force it out of you, but you're already blooming so beautifully." He thrusts and growls low against the boy's ear, biting hard enough to taste iron on his tongue.
"My beautiful little whore." Sukuna's delighted and he doesn't wait another second before growing another cock and aligning it against his pre-existing one.
Fushiguro's hole is twitching desperately, he can feel it around the cock that's shoved inside it, can feel it on the head of his new one. It's good that the boy's ass is still all messy and slippery from his loads, that way it's less difficult to press his second cock past the muscles.
Less difficult is still difficult, though. This boy was a virgin not so long ago, so he isn't prepared to take two cocks at once. Sukuna couldn't care less. If anything, it makes him more excited to do it, to conquer this tight little hole all for himself and his two fat cocks.
"Do it, do it-" Fushiguro has to catch a breath at this point, he sounds like he's going to break at any second. "Do it fucking quickly, don't stall,"
"Such a greedy slut. You know exactly what you want don't you? Very well, I'll give it to you." Sukuna shoves both his cocks so hard he fucking knows Fushiguro's eyes must have rolled to the back of his skull. He knows the boy must be prettier than a painting right now, crystal clear tears falling on the ground in front of them.
Sukuna could give him a few seconds or so to adjust. He decides not to. It's been so long since he's felt the pleasure of having two dicks at the same time, so he might as well enjoy it. The boy can handle it, he's grown up enough.
"I'm gonna make you even fuller than before." He says while closing his eyes and feeling the slicked heat involving his cocks. "Imagine how much I can come inside you with two of them, think about how brimful you'll get,"
Fushiguro's not moaning, he's whimpering and Sukuna wonders how the boy's poor brain will rationalize this later, what theoretical juggling he'll have to do to convince himself this was Sukuna's doing. Good luck for him.
"It's gonna be so pretty, trust me. You won't see it, but I'll describe it to you, okay, I'll describe it right now even because I'm already imagining it." He is, he definitely is. It's like the scene from earlier but even better. "I'll keep fucking you even after both of my cocks cum, I'll keep thrusting my load deeper and deeper so you'll feel it inside for days. I'll thrust it until it gets sloppy and starts to drip even if I didn't even pull out yet. You'll like it, won't you?"
The boy's nodding like his life depends on it and Sukuna focus on giving what they both want, not even registering when the poor kid cums, instead watching carefully his stuffed hole swallowing his cocks until one of them cums and then the other soon follows.
It's a beautiful thing, watching two cocks fuck an obedient sleeve like that. The way one of them gets soft and slips out of the hole, leaving just one cock, too small for the hole's current size, covered white with Sukuna's own cum. The way Fushiguro's still moaning softly, everything's perfect.
If it weren't the moans Sukuna might as well believe the boy was dead, with the way his legs aren't even maintaining his body anymore.
"Just so you know, kid, this wasn't even close to everything yet." He warns.
It takes a few seconds, but eventually Fushiguro answers,
"I'm well aware." Sukuna's not looking at him, but maybe, maybe that's a smile on the boy's voice. Who knows.
