Ownership

”Come on,” coaxes Dabi in a sultry, teasing voice. Normally he’s harsh and his words are rough as they break from his throat, but he’s learned how to soften his speech for this. For the express purpose of taunting the body under him, pushing it higher and further than should be possible.  

Kai’s hands are held in an iron grip above his head, and one of his own gloves is stuffed into his mouth, even though he still groans around it loudly. Dabi is fucking him in that deep, slow rhythm of thrusts that he swears he can feel in his chest, and his body is just too limp to even pretend to fight anymore. As much as he originally loved the scarred man for his raw power, the force he could exert, Kai loves him even more for this utter dominance.

“You can take more, baby. I know that you can. I know that you can open up even wider and take all my cum right up inside your body, because you’re such a good slut for me.” A scared hand grips the side of Kai’s aching jaw firmly, and blue eyes blister down into his skin.

There’s no room for argument in this, nothing to do but spread his legs wider, take more of it even as he feels the pleasure short-circuiting his mind. Every thrust is a possession, now. He’s just a thing, an object, all his power utterly useless under Dabi’s unstoppable tide.

He’s already cum inside Kai—how many times now? Three? Four? More?—and the slick of it trails down the back of his thighs in a disgusting, proprietary mess. A primal ownership, marking his territory in the most basic way imaginable and Kai hates that he’s still hard for it.

A stinging slap across his face makes him flinch and jerk, head falling to the side until that grip on his chin returns and Dabi forces their eyes to meet. 

“You. Are. Mine. Do you understand that? Get that’s what this means? Your body fucking belongs to me because I can just fill you up whenever I want to. And your ass just takes it all, huh? Greedy slut,” he coos, soft tone belying the filthy words that send thrills rolling up Kai’s spine. Dabi is speeding up, grin turning maniacal as he slides that hand down to Kai’s throat and squeezes until spots dance in the capo’s eyes. He wants to say yes, yes, I belong to you but he can’t get out the words and Dabi slams inside him with a slick slap of his hips and Kai is so close, so painfully close he wishes he could beg for more.

Until Dabi growls down and stills inside him, that last thrust pushing his cock in deep and that does it. Kai comes undone in a rush, back arching as he whimpers into the makeshift gag and the feeling of Dabi cumming inside him, hot and ready, triggers his own orgasm.

He spills against his stomach completely untouched, even as he feels himself being filled up again. And again. There will be finger-shaped bruises on his throat tomorrow and he won’t be able to walk straight for days, but this is so very worth it.
