Fuyuka has to stay at her adult nephew's apartment during a week-long business trip because her company forgot to book a hotel. She is beautiful and shapely, but her blunt, strong-willed personality has always made him nervous around her. Apparently seeing him only as family and not as a man, she casually exposes her sexy ass and walks around in sweat-dampened pantyhose after work. He cannot stop staring, and when his desire finally overwhelms his self-control, he impulsively grabs her ass.
