Miho, who came all the way from the countryside to participate, arrives at the hotel, her heart pounding with anticipation—and her pussy already soaked with arousal. Despite her petite frame and cute, girl-next-door looks, she boasts a pair of large, perky breasts. Shy in appearance, she secretly harbors a highly sensitive masochistic nature. Undergoing her first training session, she receives the ultimate enema treatment, losing herself completely in overwhelming ecstasy and humiliation—her mind and body driven wild by intense sensation.
