The reason why Ishii, a truant troublemaker, participated in the school trip was because of his homeroom teacher, Chitose. She has a voluptuous body that is hard to believe she is a teacher.

"Studying isn't the only way to go to school. Why don't you come to school little by little?" Ishii begins rubbing Chitose's big tits, which are full of gaps.
