Temporary female teacher, the seduction of Truth.

I didn't trust adults and hated my parents and Senko. I don't want to be a delinquent, but the bad guys were mostly friends. One day, a special Senko named Yamaguchi Mari came to visit. Like Tsukada, his previous homeroom teacher, he was planning to bully him and make him quit. However, Yamaguchi Mari was not just a Senko. His breasts and big butts are strong-willed, but he has a kindness that envelops him...I gradually became fascinated by Yamaguchi-sensei...
