Shiori, who has a keen sense of aesthetics, visits a certain beauty salon. On the recommendation of a male therapist, she tries an enzyme inhalation treatment for its beauty benefits, and puts on a mask to inhale... but the aphrodisiac that the man secretly mixed in takes effect and her body begins to twitch. Shiori resists, but she cannot remove the mask and continues to inhale the aphrodisiac, her brain melting, and her whole body being manipulated, causing her to convulse and arch her back as her sexuality is heightened. Eventually, she becomes addicted to the pleasure, putting on the mask herself and craving the aphrodisiac, reaching orgasms with an ecstatic expression and moaning, becoming a premature ejaculator with a body that squirts profusely... Experiencing orgasm is the shortcut to beauty.
