Ayako, who got engaged to her lover, decided to receive a female-only business trip beauty treatment salon. The esthetician is a man and develops Ayako's anal with special oil and technology. From that day on, Ayako became captivated by the pleasure of anal and masturbates like crazy, but she can't enjoy the pleasure she received from the esthetician and spends days in agony. Ayako who became unbearable again asks the esthetician for anal training. While lying to her lover, Ayako becomes an esthetician.
