Shiori, who has a high sense of beauty, visits a certain beauty spa. At the recommendation of a male therapist, she tries inhaling beauty-enhancing enzymes and puts on a mask to inhale... Then the aphrodisiac secretly mixed in by the man takes effect, and her body starts twitching. Shiori resists, but the mask can't be removed, and she continues to inhale the aphrodisiac, her brain melts, and she is played with as she pleases, her whole body is manipulated, and she is developed sexually to the point of convulsing and arching her back. Eventually, she becomes addicted to pleasure, puts on the mask herself, seeks aphrodisiac, climaxes with an ahegao face and oho voice, and falls into a premature ejaculation body that cums wildly and squirts... Feeling orgasm is the shortcut to beauty.
