Bathroom

Ben presses his nose into his cousin's white, sweat-stained panties, inhaling the musk, licking, sucking the gusset, and stroking his shaft vigorously. 'I don't know why I can't stop.'
He wraps her underwear around his member, moving his hips, grunting. 'I have been in the bathroom since.. I lost track of time.' He imagines pinning his cousin, her plump, round butt hovering his dick, and spreading her legs wide open. 'Gwen, she is my cousin, that's sick!'He is on the edge of shooting his load until he hears a knock on the bathroom door. "Ben, what are you doing in there?"He ponders what would happen if he opens the door and shows her he's about to cum on her underwear. "Are you alright, Ben?", she voiced her concern, pounding on the door while twisting the knob.
