Somehow - somehow, Dave's not even sure when it happened, or how, or why - one of Dave's hands has found it's way off Gamzee's hips and onto the troll's bony hand, gripping hard enough that he can feel those oddly thin and delicate bones digging into his skin.

There's nothing in his mind anymore - it's gone completely blank, completely taken over by the desire burning through him, by the heat coiling at the base of his dick. All he wants now is for that coil to snap, and it makes his grip tighten on Gamzee's hip, tugging the troll as hard as he can into those short, sharp thrusts of his hips.

His rhythm falters, suddenly - that's always the end of it. That place his body finds where it can't even maintain a beat anymore, his heart and his breathing all out of sync, not even syncopated, but just wild, and his hips stutter up off the ground once, twice, all the muscles in his body drawing tight - and then he's gone, his nails digging into Gamzee's skin, a shuddering moan spilling from his mouth, his back arching to a nearly impossible angle.
