You're going to leave the toybox in the closet tonight, because you are fairly certain that you can ruin him six ways to Sunday without even a pair of fuzzy handcuffs to back you up, and you really don't want to give the poor guy an aneurysm or something.

Equikat, everyone's a dom or sub AU. -- The thing with Equius is, he's huge, and he's ripped, and he has a low, carrying voice, and he's bossy as fuck. Before he started wearing Karkat's collar he let people who were not directly concerned assume whatever they wanted out of his hearing, and he never came back home weary, never went straight to Karkat's desk to kneel there at his feet, silent and drawn in and waiting for a hand to caress his hair like he was a statue on the verge of crumbling into dust and only Karkat's touch might ward off that fate.
