As a person with a high sexual desire but Suzuki is not satisfied by her husband, she always has to masturbate, imagining someone having sex with her every night.
During a time when her husband went to work, her brother-in-law came to play, Suzuki talked about her suffering, the other brother began to understand the problem and the boy took the initiative... seducing his sister-in-law.
Although she was more than afraid at first, Suzuki resisted, but after just a few minutes she had a fever and began to "respond" to her brother-in-law's desire to use her husband's wishes.
