A brother and sister, both horny and frustrated, find themselves alone in the house. The sister, curious and adventurous, suggests a game of truth or dare. The brother, always up for a challenge, agrees. As the game progresses, the dares become more risqué, culminating in the sister daring the brother to fuck her. He hesitates initially, but the sight of her naked body, her pussy glistening with desire, pushes him over the edge. He takes her, hard and rough, just as she dared him to.
