[The sound of his name coming out of Denji is enough to make Aki finish. He can feel the way his body changes as Denji comes against his own stomach, spurting onto the door and dripping to the floor. Yet he's still moving against him, still slurring his name like he's drunk off it. Aki keeps grinding into him, fucking deeper every time, as if he can carve more out and hit diamond if he doesn't give up. He can hear himself panting and his orgasm feels so close, the repeated sound of Denji's voice in his ear - Yes, sir, how hard that had made his dick jump - and the delight of friction when he squeezes his arm and twists it against his back. He leans into his shoulder and nibbles at his skin before biting down hard, digging his teeth into the flesh as his hips buck before grinding hard into the tight heat. When he comes it's almost obscene, Aki spilling violently into him and filling him until he's fucking his own release into his hole, like he wants it to take.]

[He would always stop after this. Lean back and take a breather. Aki releases the skin from between his teeth but that's about as much of a reprieve as Denji gets. He keeps thrusting, pushing his chest into the door with a shove to his back, then drags his hip toward himself and groans against his neck. He doesn't want to give him up yet. Doesn't want to give him the excuse to get up, to run. The longer he can fuck him, the longer he can own him.]

Keep going - There you go, just, fuck - [He can hear the awful noises of his own come inside of him, lubricating his cock poorly but better than it was before.] Be good - Keep going, Denji, just be good and keep going... [The hand on his hip wraps around to hold his stomach as he drags Denji against him and keeps thrusting up into his dripping hole.]
