Nishinomiya Yume, a slender gyaru, joins a hot yoga class in pursuit of better health. However, she becomes the target of inappropriate stares from men in the room. The water she drinks has been laced with an aphrodisiac, unknowingly triggering intense sweating and arousal. Unable to control her body, she convulses repeatedly, reaching orgasm after orgasm, her spandex soaked through with arousal. Overwhelmed by the drug's effects, she plunges into one drug-induced climax after another, her eyes glazed over, drool dripping from her lips as she wears a blissed-out expression, passionately losing herself in pleasure. Her splayed, drenched thighs spasm continuously, fully consumed by waves of orgasm.
