Natsu, an honor student attending a school in Tokyo, is a serious and justice-oriented pupil who belongs to the dance club. One day, while practicing alone on the rooftop, she catches delinquent student Suzuki smoking and scolds him. Then, teacher Kato appears and reprimands Natsu, but it turns out that Kato is also a delinquent teacher... During the summer vacation, this short-haired honor student with black hair is transformed into a lustful woman through intense, impregnation-guaranteed group sex by perverted men.
