Hazuki Wakamiya, who once thrived as an M-female at an SM club, is forced to quit after a conflict with a client. Encouraged by a chance encounter with a fortune teller, she decides to switch careers and join a specialty brothel focused on nipple torture. There, she restrains male masochists and overwhelms them with intense nipple play and verbal domination, bringing men to hands-free ejaculation with her expert techniques. Hazuki calls out to stressed men: "If you're holding back your cum, come see me!" This charismatic nipple princess, devoted to ruining both nipples and penises, now draws admirers from far and wide.
