At the end of summer appears a perverted older sister—by day, a professional esthetician working at an exclusive members-only luxury spa. But driven by an intense craving for deviant sex, she makes her AV debut. A supremely sensual masochistic woman trained by wealthy perverted old men from Ginza's elite circles. Despite her refined appearance, she harbors outrageous fetishes and insatiable lust, getting off on self-administered deep throat. She politely begs for rough thrusting, screaming for orgasm. Her pursuit of ultimate pleasure captivates all who watch.
