"The most pleasurable sex I've ever had...I don't really remember it."Risako Nishiuchi, 46, a full-time housewife. Married for 18 years, mother of two children. Since getting married, Risako has been devoted to her husband. Her Kokoro started to waver when she found out that her husband was visiting a brothel. "I guess I'm a masochist at heart, but I'm more concerned about whether the other person is feeling good than whether I'm feeling good. With my husband, I have sex because I'm happy when he's happy. Afterwards, I masturbate in the bathroom (laughs)." Her husband betrayed her, whose identity is to serve such a man. "One day, I was drunk and brought a colleague home, and he said, 'I can't believe you have such a nice wife, but you enjoy prostitution as a hobby.' Is that possible (laughs)?" The shock of visiting a brothel, and the shock of realizing that the sex that she had been serving to her husband until now was just a substitute for prostitution, led her down the path of infidelity. Today, you will be immersed in your own pleasure to your heart's content!
