48-year-old Yukie Nakayama. Married for 22 years, she currently works part-time at a supermarket. Her marital sex life occurs about once a week. Though she's had several affairs in the past, they were always with men who just wanted physical gratification—there was never deep emotional connection or passionate desire between them, and truly intense sex has been nearly nonexistent. For Yukie, sex isn't merely about seeking pleasure; she longs to move her body wildly, to be taken so thoroughly that she begs for it to stop—just once, she wants to experience that. Searching for such a fulfilling encounter, she's now filled with lustful desire. It's hotter than early summer should be, and inside the bedroom with the air conditioning turned off, male and female pheromones fill the air. Drenched in sweat, they indulge in sticky, raw, and utterly pure pleasure. This overwhelming passion—this is what Yukie truly believes real sex should be.
