Two siblings, Michelle and her brother, find themselves alone and bored. Michelle retreats to the bathroom, masturbating furiously, her fingers slipping in and out of her wet pussy. Her brother walks in, catching her mid-act. They argue, Michelle's anger boiling over, but later, they make amends. Naked, Michelle admires her brother's thick cock as he jerks off. She can't help but imagine it inside her. Just as they're about to give in to their desires, someone walks in, halting their incestuous encounter.
