Animation Sex Movie - Oshioki Gakuen Reijou Kousei Keikaku 3

Shimohei Joutarou is my full name. Because the school year has not yet begun, I am working at my new place of employment. I discovered Mitsuki and Minami's secret almost immediately on the first day of class. This led me to learn about the remarkable rise in grades of Kuji Hinako's younger sister, Mahiru. I then uncover hints of Hinako's backdoor manoeuvres. Those teens who have broken the rules must be brought back into compliance by my efforts.
