Teen sister, left home alone, can't resist her raging hormones. She starts slowly, caressing her young body, imagining her brother's touch. He catches her, hard and ready, in their parents' bedroom. They freeze, then give in. She takes his virginity, eagerly sucking his cock, then riding him on the bed, their parents' bed. They climax together, her tight pussy milking his cock, before cleaning up and sharing a guilty, satisfied smile.
