"Natsu", an honor student who attends a school in Tokyo, is a serious student with a strong sense of justice and belongs to the dance club. One day, "Natsu", who came to practice alone on the roof, witnessed her delinquent student "Suzuki" smoking and warned him. Then, her teacher "Hito" also appears and reprimands "Natsu", but in reality "Hito" is also a bad teacher... During the summer vacation, an honor student with short black hair was transformed into a lewd woman by sweaty vaginal cum shots by vulgar men who were bound to get pregnant.
