An ordinary high school girl. One day, she realizes that she has an incredibly strong sexual desire. She is a perverted girl who masturbates in the school toilets and the train station toilets. On school holidays, she spends all her time masturbating. Wanting some extra cash, she signs up for a perverted job site. At first, she thinks she'll quit once she's saved up some money, but as she works, she becomes addicted to the pleasure. Even today, somewhere, she's probably satisfying her sexual desires with older men with insatiable sexual desires.
