APNS-057 Sakura Haru, a beautiful girl possessed by a desire to expose herself

Haru, who has been an honor student since childhood, had a habit of going out at school and around town without panties. He goes to Kita's house, a middle-aged man next door to her girlfriend, and exposes himself and masturbates without anyone finding out. Kita's younger brother, Ippei, sees her doing this and is forced to tell his parents, so she becomes compliant. She is tied around by Ippei and Kita, and their pure pleasure is trained into their innocent bodies. Eventually, Haru grows into a true pervert.
