In her 15th year of marriage, Yorimiya Rino (40), a housewife living in Suginami Ward, found intimacy with her husband had become a mere obligation, leading to several sexless years. Originally, they enjoyed a passionate, loving relationship filled with enjoyable sex, but over time, their connection turned mechanical and duty-bound, creating emotional distance. Eventually, she decides to seek fulfillment elsewhere. "Sex shouldn't be forced—it shouldn't feel like just another chore," she admits with a wry smile. Realizing she can't revive her marriage, she turns to strangers, hoping to experience a simulated romance. She makes the decision to cheat—and finally rediscovers passionate, affectionate lovemaking, stepping into a new world of pleasure. Once awakened, her body begins craving bolder, more intense, and deeply passionate encounters. Her desires grow stronger, driving her into increasingly fervent and insatiable sexual relationships.
