Hidden in her room, the curious sister explores her desires, her fingers dancing on her clit, building pressure. Her brother, hearing her moans, investigates and catches her in the act. Embarrassed, she flees, only to return, emboldened, and demanding his touch. He obliges, his fingers replacing hers, driving her to the brink. As she screams her release, her pussy gushes, drenching them both in her torrent of desire.
