The teen siblings, Michelle and her stepbrother, find themselves alone in the house, their hormones raging. Michelle, curious and horny, starts to masturbate, her fingers slipping in and out of her tight pussy. Her stepbrother, hearing her soft moans, enters the room, catching her in the act. Instead of leaving, he joins her, his own hand wrapping around his hard cock. They watch each other, the air thick with tension, before Michelle can't take it anymore. She straddles him, guiding his cock into her virgin pussy, gasping at the initial pain that quickly turns to pleasure.
