unckuna 🥹
Sukuna is heavy.
It's a nice weight, you think. Blanketing and comfortable as he bears down on top of you. The weight makes sense; he's firm and sturdy and broad through his shoulders, tapering down into a trim waist that you can't think about for too long or it makes your head spin.
He's warm too.
There's a heat that seems to perpetually radiate from him, regardless of the climate, against all odds. It's just as soothing as his weight to seek out and leech from him—particularly when the two of you are out in the cold, inching closer to him on the sidewalk just to fight the frigid breeze or twining your fingers through his own to keep your fingertips from pricking with the chill. His hands are one of your favourite parts of him, usually.
But not at the present moment.
"Sukuna—" the warning is lost to his esurient mouth, mumbled into soft lips and swallowed down before it can elicit any actual response. Sukuna has you pinned down on the sofa, underneath his warmth and weight, and those hands you usually like so much are creeping dangerously up, up, up under the hem of your t-shirt—even in spite of your repeated insistence that this wasn't allowed to proceed any further.
His breath huffs against your slick lips, a laugh you think, and that familiar heat of his hands slithers back down towards your waist like it has every other time you've cautioned him.
"Stop bein' a tease," he mutters, slipping one hand underneath your back and pulling up so your spine arches and presses the two of you even closer together in that impossibly narrow space you occupy on the sofa.
Your breath hitches as your hips grind against his, and the look on Sukuna's face is deeply pleased by the sound. You huff a little. "I'm not teasing."
"Yeah fuckin' ri—"
"Yuuji's only down the hall," you don't even let him finish his snark, chastising him firmly.
"He's asleep," the man above you tries to reason, dipping down to nip at your pulse. Sukuna's nephew had only fallen asleep a short while prior, and as sweet a little boy as he may be, you were all too conscious of his bloodline—you didn't trust Yuuji to stay asleep any more than you trusted his beloved jichan to keep his hands off you, just because you said so.
Using the hand he still has tucked underneath the small of your back, Sukuna effortlessly tugs you up against him. Everything spins as you're righted, and before you know it you're straddling his lap on the sofa in his older brother's humble apartment, peering down the dimly lit hallway in the direction of Yuuji's bedroom. Sukuna mouths at your chest through the thin material of your shirt, sucking against the visible bud of your nipple. He'd weaselled you out of your bra soon after the two of you started fooling around—what had started off as a bit of innocent heavy petting—slipping it off and tossing it somewhere in the living room, and you've lost track of it now that things had kept spiralling out of your control.
You should have known this was how things were bound to turn out when Sukuna had asked if you'd accompany him to babysit his nephew that night. You had plans to see a movie, maybe grab dinner, and then almost assuredly end up bent over some piece of furniture in your/his/a hotel room by the end of the night. That's how things usually go with Sukuna. But then Itadori Jin had called his younger brother only a short while before the two of you were planning to meet, pleading with him to watch Yuuji for the night since he had to stay late at work.
When you first learned Sukuna had a nephew, more by accident than anything, it had surprised you. He didn't strike you as the type to get along with children when he barely gets along with other adults. Then you met Yuuji—even more by accident than simply finding out, happening to cross paths with them one afternoon—and it surprised you even more to see with your own two eyes just how deeply he cares for him. Upon first impression, Sukuna is rough and crass and unsympathetic—and while yes, those things might be true to some degree, the more you've come to learn about him, the more you've come to see other sides of him that you're not sure many (if any) other people have the chance to.
You spent your evening playing games and colouring with Yuuji while Sukuna prepared his dinner (which Jin had left in the fridge, but still, there was a certain level of preparation involved.) The three of you ate together at the kotatsu in the living room, and you laughed every time Sukuna barked at his nephew to stop trying to sneak his vegetables onto your plate. You watched Sukuna and Yuuji roughhouse before collapsing into a pile on the sofa to watch a movie, watched the six year old fall asleep on his uncle's arm, watched said uncle pluck him up (more delicately than you've ever seen Sukuna treat anything) and eventually take him to his room and tuck him into bed.
The Sukuna you thought you met six months ago would have never changed all his plans, with relatively little hesitation or complaint, to babysit a six year old, and he certainly would never have invited you along to accompany him—a bit awkwardly, endearingly clumsy—just so the two of you could still spend time together.
Sukuna pulls away from your chest, a little string of saliva stretching from his mouth to the wet stain he's suckled into the material of your top. He blinks up at you, eyes heavy lidded and gaze hot. You trace your fingers through his unkempt hair, brushing it back from his brow.
"What?" he asks, his tone guarded, as though he's suspicious of how gentle you've suddenly become. "Aren't you gonna tell me to—"
"Hey," you cut him off, your hands settling on his shoulders. He pauses, his lips still parted in speech though the words have stopped. "Kiss me?"
There's not a moment wasted before he cranes up, obeying your request without any hesitation. Maybe it's because he doesn't want to give you the chance to change your mind. Maybe it's because he can't say no to you. Maybe it's because he wants it just as bad as you do.
This time you don't stop Sukuna when his hands slip up your top. Don't stop him when he takes it off all together, either. He's not as talkative as he usually is, having grown used to the way he likes to mouth off when the two of you are intimate like this. He's as conscious as you are of his nephew sleeping only a few rooms away. He's careful with you, not unlike how like he was with Yuuji, in his own particular way.
You don't plan to stop him at all, anymore. Your resolve to deny him (and yourself) having melted under a strange warmth you feel kindling in your chest. You're happy to let him—the Sukuna you think you might be the only one who knows—have you.
Or, you would be, if not for the unexpected return of his older brother, who flicks on the light in the living room with absolutely no idea what he's about to expose.
Thankfully you've learned from experience that first impressions aren't so important after all.
