42-year-old housewife Hiroko Mouri. Currently in her 13th year of marriage, she lives with her husband and 11-year-old daughter. She began feeling dissatisfied with sex shortly after getting married. Since it was an arranged marriage, they hadn't placed much importance on their sexual relationship. Sex had initially been approached as merely a means for conceiving children, but after giving birth, the frequency gradually decreased. Over time, she started reminiscing about past relationships. Her previous boyfriends were mostly aggressive, dominant types—the kind who gave clear commands and took control, which she found appealing. However, when choosing a husband, she decided she wanted someone gentle. Deep down, she held onto the feeling that a man's pleasure overlapping with her own was profoundly satisfying. Her desire for complete service and submission defines her sexuality—an irresistible allure that will undoubtedly captivate anyone.
