Under the guise of a sleepover, sisters invite their brother to join them in their queen-sized bed. They wear only skimpy pajamas, their curves evident in the moonlight. The brother, initially hesitant, joins them. They start innocently, but the sisters' hands begin to wander, tracing the lines of his abs, his chest. He responds, his hands cupping their asses, pulling them closer. They grind against him, feeling his growing erection. Their kisses become more passionate, their hands more exploratory, as they give in to their incestuous cravings, their moans echoing in the silent house.
