As they lounge together, the tension builds, and the younger sister can't help but touch herself, her hand slipping under her skirt to stroke her wet pussy. Her brother catches a glimpse of her illicit act, and his cock hardens in response. They lock eyes, the air thick with unspoken desire, as they struggle with their taboo feelings.
