A bored teen sister and brother, stuck home alone, can't resist the temptation of each other's bodies. Michelle, a busty ebony teen, starts by pleasuring herself in the bathroom, her moans echoing. Her brother, catching her mid-act, joins in, his massive cock throbbing with desire. They argue, then make up, deciding to masturbate together. Michelle's eyes widen as she takes in her brother's size, fantasizing about him filling her tight pussy. Just as they're about to cross the line, a noise startles them, forcing them to halt their incestuous encounter.
