On the day of the school trip, the class president with no serious friends is found masturbating in her room by a super-sexual physical education teacher, and she endlessly rapes creampies in 3 nights and 4 days

Today is the day of the school trip that everyone in the class was looking forward to. I want to make memories with the guy I like, but I can't speak well... On my day of free movement, I masturbate to comfort my nerd, dark self. There, the demon teacher Setune appears. That's bad! I'm also going to be prey to the rumored extreme perverted play! ?
