on god the first time dave convinces karkat to let him fuck him in the ass... that boy came so hard that his genmat reached daves fucking chin

daves fingers feel weird as they slowly work karkat open, the troll completely unusued to even the idea of it-

but dave is so clearly excited that karkat is forcing himself to get over his reservations

so he lets dave finger him open, squirming a little at the strange feeling, but its kinda nice- deep and shivery up his spine

then daves pressing his dick into karkat and the stiff head of his dick is slowly pressing him open and /oh christ/ its weird and /good/ and karkat is chittering helplessly, staring at the ceiling

and when dave asks him if he's doing good, karkat can only nod because it /is/ good- its so weirdly, weirdly good

and dave starts rocking and gently fucking into karkat and and feels like a fucking fever dream. the slow drag of daves cock inside him is making his legs shake,

his breathing go staggered, and he begs for more- so dave gives it to him. he gradually amps up his thrusts until the bed is creaking, fucking into karkat roughly, watching karkat moan and bed underneath him as his bulge twists and wiggles between their stomachs

when karkat cums, he cums with a /shout/, legs going tight around dave as his bulge spurts genmat, shooting up between them, across Karkat's stomach and chest, splattering his chin as he sobs, wracked with a deep and intense gut-shaking pleasure
