Bored siblings, Michelle and her brother, are left alone in the house. Michelle retreats to her room, her mind wandering to forbidden thoughts. She starts touching herself, her fingers tracing the outline of her panties, feeling the dampness growing. Her brother, hearing her muffled moans, can't help but imagine her, his cock hardening in his pants. He decides to join her, knocking on her door. They both know they're playing with fire, but the desire is too strong. They start masturbating together, their eyes locked, the tension building. Michelle can't help but wonder what it would feel like to have him inside her.
