Yume visits a hot-yoga class for her health, only for a man to slip an aphrodisiac into her water. The slim gyaru begins sweating and growing aroused without realizing why. She hates his touch, but her drug-sensitized body cannot stop convulsing through orgasm as her fluids soak through her leggings. Overwhelmed by the chemical rush, she repeatedly climaxes during drug-fueled sex, drooling with glazed eyes and a wild orgasm face as she begs for more cock.
