A certain massage parlor in Tokyo, this is a famous salon that specializes in spot weight loss. It has a good reputation on the Internet for being a safe place to receive treatment even for the first time. However, there is a therapist here who will flirt with women. The woman who is targeted is forced to drink tea laced with an aphrodisiac, which unconsciously increases her sensitivity, and she uses clever words to justify the obscene treatment!! By the time she realizes, it's too late... the aphrodisiac rubbed into her mucous membrane makes her more sensitive than ever!! Her reason collapses as she squirts for the first time!! The aphrodisiac turns her into a female and she can't make normal decisions, so she can do whatever she wants to the customers! Big-breasted girls become prey to the powerful aphrodisiac, which makes their memories after the treatment vague!!
