Fuck Buddies With Miss Prim and Proper

Koharu Sakura is the class president, a neat and cute girl. One day, I witnessed her masturbating at school. I suggested we work together to satisfy our sexual needs, and to my surprise, she agreed and we became sex friends... She's usually a quiet girl, but she's actually a sex-crazed monster and a carnivore when it comes to sex! We secretly have sex at school, and we they go crazy with each other at a love hotel.
