32-year-old Yuki is a housewife. Raised since childhood in isolation from the outside world, she grew up as a pure and innocent young lady. Having had almost no contact with men, she didn't even have sexual experience in her private life. After turning thirty, her female instincts suddenly awakened, leaving her in a state of sexual frustration. Cruel men noticed her emerging sensuality and made her their target. Though she had intended to resist, for some reason she chose submission on her own. Her body writhes in frenzy as she's taken by strangers' dicks in public places—her actions suggesting she had secretly craved this kind of perverted sex all along.
