A schoolgirl is suddenly given an aphrodisiac by a stranger. Soon her breathing becomes rougher, her hips twist, and her crotch begins to ache! The schoolgirl can't hold back until she gets home, even though she notices something strange happening to her body. She masturbates outdoors, "in the middle of the road!" "on the handrail of a bus!" "on an eggplant at a BBQ!" etc., while being mindful of her surroundings! Then, when the man attacks the schoolgirl, who is feeling so much, she goes crazy with instinct!
