The poster girl for the massage parlor, Rie, has huge H-cup breasts. Regular customers get excited by the touch of her breasts during the massage, and mistakenly assume that erotic acts are OK, so they force themselves on her. Rie is enthusiastic about her job and never forgets Kokoro of service, so even though she's embarrassed, she ends up giving him an erotic massage using her breasts. Her senior tells her that this is a new treatment, and oil is applied to her big breasts, leading to sex.
