Hidden cam captures my stepdaughter's naked body and masturbation

The video begins with a young girl, a brunette with a slender body and perky breasts, entering a bathroom. She is wearing nothing but a towel, which she quickly drops to the floor. The camera, which is hidden in the room, captures every detail of her naked body as she begins to masturbate. Her fingers move slowly over her clit, as she moans softly with pleasure. Suddenly, the door to the bathroom opens, and a man, presumably her stepfather, enters the room. He is startled to see her naked, but she quickly reassures him that she is alone. The man leaves, but the girl continues to pleasure herself, unaware that she is being spied on by the man. The video ends with the girl finishing herself off, her body shaking with orgasm.
