MEYD-815 Collective sadism of my friend's sister....

Five years after becoming a teacher, Hitomi lives happily with her husband. However, there is a seed of trouble in sight... It is the existence of Iijima, a truant student. Hitomi goes to Iijima's house out of a desire to get to school as soon as possible. However, what Hitomi sees there is a shabby and dilapidated room. Iijima is going crazy inside. And Hitomi will be violated. The next day, Iijima threatens him and takes him to an SM love hotel, but Hitomi still doesn't know about the sadistic nature sleeping within her...
