Hikari, Hibiki, and Mei, the most beautiful girls in the school, are great friends and always act together. All three of them fell in love at first sight with a male teacher who was able to practice teaching! After secretly having a physical relationship in an empty library, we compete for big cocks in the classroom at the infirmary! Under the guise of a summer training camp, the car was sent out and they asked each other like monkeys in the Japanese-style room of the inn!
