Minami is a married woman who works in the accounting department of a company. She has been using her position to commit fraud. One day, a man notices Minami's suspicious behavior and confronts her. He demands that she give him her body in exchange for keeping quiet. Minami resists, but fearing that her fraud will be discovered, she gives in. The man holds Minami's secret and plays with her body. The man's demands become increasingly intense and perverted, and Minami, obeying him, becomes addicted to his perverted acts. The man calls her to a tatami room, where she obeys as he requests, as usual. After she has orgasmed and is tied up in a daze, the sliding doors open and employees from the same company pour in from the next room. Minami secretly smiles at the glaring gazes of the employees.
