Married to a hardworking husband, mother to a cute boy, caretaker to her husband's father. They're a happy, normal household of four. Yet... Chigusa's husband comes home late and exhausted. It's a good marriage, but she has yearns for his embrace. When they do have sex he finishes in a few short minutes in the missionary position. It's not enough for Chigusa. Her sexual frustration has reached boiling point.
