This PRESTIGE production features four wildly perverted amateur girls, each with unique sexual desires. By day a college student, by night a G-cup university girl named Sakura working at a high-class Ginza club. She fully exploits her voluptuous body for money and erotic techniques. Yuki is a nurse by profession, but in reality a perverted exhibitionist who lusts after cock. Working at a urology clinic, she turns her job into a playground to satisfy her own desires. Aya is a theme park employee who selflessly offers her body to earn living expenses, always displaying her insatiable pursuit of pleasure. Also appearing is Hikari, a college student who has nurtured deviant thoughts since childhood. These four "Hidden Gems of SEX" gathered from across Japan deliver a four-hour experience of indulgence, each showcasing their unique charms.
