Two-night, three-day creampie school trip with a busty female teacher

The reason why Satozaki, a problem child who had been refusing to attend school for a long time, decided to take part in a school trip. This was to rape Sachiko, the homeroom teacher who had been caring more than anyone else for a while. She was aiming for the opportunity to keep the eyes of adolescent male students in their lives, and to keep the lewd, busty body of Sachiko, who has captivated even her parents and male teachers... Late late at night on the first day of the trip, Satozaki saw Sachiko heading to the open-air bath by herself, and suddenly stroking Sachiko's big bust, which had been exposed, in the changing room, from behind. "Satozaki-kun! What are you going to do?!" "It's okay, it's already time for everyone to sleep..." Three long, short, unforgettable days have begun for the two of them.
