Chigusa Nasuno, age 32.
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.
