A female student takes her eyes off the bicycle, and someone uses the opportunity to smear a large amount of aphrodisiac on the saddle. Unaware, she straddles the soaked saddle, and the aphrodisiac seeps from her panties into her vagina, making it impossible for her to hold back as she starts masturbating on the saddle. Unable to endure it any longer, she even urinates on the street. Then, they drag the staggering female student into a blind spot where, despite resisting, her overly sensitive body is completely controlled by the man, and she begins to go wild with pleasure.
