quickie where sub is promised they can pee once their dom cums. getting bent over a bathroom sink or something, pants pulled down around their knees, sensitive bladder being jammed up against the counter every time their dom fucks into them.
they manage to get through until their dom is finished, but their dom just yanks the sub's pants back up, buttons them, and holds the writhing sub there until they have no option but to wet themselves while still squirming and mumbling how unfair it is
