Married woman 'Riko' who is suffering from secret debt to her husband. On her way home from shopping one day, she boarded a bus and found Takimoto, a debt collector, on the bus. Riko is molested on the bus because she can't go against her Takimoto, and her body is played with. Even after that, Riko had no choice but to obey Takimoto, and her escalating molesting act made her body ache.
