A schoolgirl is suddenly given an aphrodisiac by a stranger. Then, the aphrodisiac gradually takes effect... her breathing becomes irregular, her hips twist, and her crotch throbs. The schoolgirl can't wait until she gets home, so she masturbates outdoors, avoiding the prying eyes of others, using the water faucet, a bicycle seat, a vibrator she picked up, etc. Then, when he attacks the heated schoolgirl, she becomes obedient and cums over and over again!
