Bored and horny, a young woman sneaks into her brother's room, finding him asleep. She decides to take advantage of the situation, stripping and straddling him. As she grinds on his lap, he awakens, initially confused but quickly aroused. She begins stroking his cock, her tight body rubbing against him. He grabs her ass, pulling her closer as she jerks him off. The tension builds, and just as she's about to make him cum, he flips her over, taking control and finishing on her stomach.
