Akio became the president of a mid-sized manufacturing company at a young age. His wife, Michiko, got married as a virgin and has been devoted to her husband ever since. He is beautiful and chaste, and uses his professional piano skills to teach piano lessons. For Akio, she was all about his wife. But should such a wife be prevented from experiencing another man for the rest of her life? If my wife is embraced by another man and she loves me even more than that, wouldn't that be true marital love? That's what I secretly started thinking. Akio brought a camera into his bedroom and began filming Michiko naked. Michiko resisted at first, but she gradually began to open her thighs. And I started to want stronger stimulation...

Keiko becomes the second wife of Shizuo, the owner of a real estate company whose wife died in the Great Hanshin-Awaji Earthquake, through an arranged marriage. Despite the 20-year age difference, they are happy at first. However, as the company's financial situation worsens, their married life becomes colder, and Shizuo shows no interest in Keiko's advances. Around that time, Shizuo's son, Akira, who is not working much, begins to pressure Keiko into a physical relationship. Keiko, feeling lonely, accepts and becomes obsessed with sex. Then, when Keiko starts working part-time as an insurance salesman, Akira proposes that she murder Shizuo for the insurance money...
