In this amateur video, a brother and sister, left alone in their home, find themselves drawn to each other's bodies. The sister, feeling neglected, begins to masturbate, her fingers plunging into her wet pussy as she fantasizes about her brother's thick cock. Caught in the act, they argue, but soon their desires override their inhibitions. They strip naked, the brother's massive cock standing erect as he jerks off, and the sister can't help but imagine it inside her. Just as they're about to give in to their taboo lust, a sudden noise forces them to halt their erotic encounter.
