Stuffed full by one of Sukuna’s big dicks and the pups inside his belly, Yūji is shy and sweet, no more the boy who was forced to fight before. He has become quieter, his pregnancy progressing so well.
It’s practically an illogical change, something that they wouldn’t have believed so many months before. Years, actually.
Reality is that Yūji is indeed living with him, overlaying their existences, the bite on his nape a declaration of his human fate bonded to Sukuna’s now. The two pups growing inside are just fulfilling Yūji’s promises, proof of how much love has reached Sukuna.
A lot of people, though, want them dead, but as long as his omega’s alluring and sweet scent fills his nose, Sukuna won’t let anyone get closer to them.
Reality is that Sukuna has bred his brat. He claimed him, made Yūji his, and put his alpha seed until it dripped from the brat’s cunt.
The results delight Sukuna.
“So fascinating, my bitch. Look how heavy you are with my pups,” Sukuna murmurs against Yūji’s face, looking down between them, a pair of hands reverent around the too evident bump of his little mate, another hand supporting behind Yūji to help the omega fuck himself on one of Sukuna’s hard erections. “So fucking big now.”
Yūji moans embarrassed, but even so, he still tries to press down, cunt lips swallowing more of his alpha’s cock.
“Sukuna! It’s so—” Yūji gasps, reaching his limit by now and starting to roll his hips up and down on Sukuna, so careful but moaning as a needy whore because he can’t help it. It feels so good, always craving it, hormonal for any of his alpha’s attention and cum.
The Yūji from his past wouldn’t believe it. He wouldn’t even accept how much he loves having such dangerous pups inside him, how Yūji looks right now as he doesn’t protest when Sukuna’s free hand moves to cup one of his sensitive, blooming breasts, soon to be allowed to feed, to nurture— to do that either for their pups or Sukuna.
“Hush, my brat,” Sukuna says as the mouth of his stomach opens, the giant tongue licking softly around Yuji’s bump. “Just keep doing this and I will take care of your existence forever.”
Yūji’s omega instincts love hearing that, adoring how such a strong and smart alpha is at his side.
His hole is so slick—the sweetest thing like Sukuna sometimes has called it. It's perfect for the thick cocks of the large alpha.
“Knot me, p-please.” Yūji’s cunt sinks wetly further down, making a squelching noise as he keeps riding the father of his pups, walls spamming around the swollen flesh, promising a knot if Yūji keeps being a good boy. A good bitch.
Sukuna pushes his hips up, immediately making Yūji yelp, smaller hands gripping harder around the alpha’s neck as his heavy body squirms when his cervix is touched in the most delightful manner.
“Love you,” Yūji pronounces as his eyes shut down and his head presses back against Sukuna’s hand behind his pink hair, so much pleasure traveling through his body.
“Me as well,” answers back Sukuna before his lips catch around one of Yūji’s nipples, sucking. As always, it drives Yūji wild, even more so while knowing that the sensation will be closer to something much better the day when milk starts to dribble out from his breasts. At this mental sight, Yūji’s hips, still rocking back and forth, increase the pace as much as he can as his slick and warm walls flex around the monstrous cock. Sukuna releases the nipple only to promise, softly, “I won’t allow anyone else to have you.”
Like this, so sensitive, Yūji comes, his nectar dripping down on Sukuna’s lap.
“Alpha!”
Sukuna starts to thrust into Yūji with careful deliberation, mouth in Yūji’s nipple again, fucking his pregnant omega but not doing anything too rough. He can behave patiently as his knot is so close to forming. He’s a strong man, still the King of Curses.
“Yes! Alpha!” Yūji gasps despite still feeling the pleasure of his orgasm, too content with his current life, moving his poor hips down, grinding the flesh that’s about to lock him with Sukuna. “So good! Knot me! Ah! Please…”
The alpha growls in pleasure, hands gripping Yūji a bit harder, drunken by the omega’s scent, still hearing the squelching noises of their lovemaking.
They’re in Yūji’s nest, arranged to allow inside a bulk man like Sukuna, the soft materials of furs and blankets hugging their weights, so distant from that place of bones when Yūji was his vessel. He’s his little mate now, accepting Sukuna and his pups, and the sight of Yūji and his round belly bewitches Sukuna, no doubt about it.
It’s a victory.
“So perfect,” Sukuna can’t stop himself from saying—he would say it from now on. It’s what his mate deserves by having his wet pussy lips clenching and spreading so well around his cock. “Omega! My perfect bitch!”
“Yesss.”
Sukuna’s knots finally form, the swollen flesh fucking Yūji catches on the slick hole, sheathing his claim into him. Both engorged heads spurt so much quantity of semen as one stains the globes of Yūji’s ass and back and the other makes Yūji cry when another orgasm reaches him the moment he feels his womb being filled again, his whole self pleasantly overstimulated.
The knot inside Yūji locks them together as many times before, and although Sukuna thinks for a brief time how much he misses fucking Yūji with both his alpha cocks, he’s patient. He’ll fuck his mate pregnant again in a few months, breeding and ruining the young sorcerer after he becomes a mother.
For now, as he splits Yūji’s puffy cunt lips open, one of Sukuna’s hands holds him by the chin before he kisses him.
Yūji shivers, his whole body about to fall into Sukuna’s embrace.
Breaking their kiss, Sukuna makes another promise for them. “I’ll put more pups in you as soon as you give birth, my brat.”
Yūji smiles, adoration on his golden eyes.
