Newly-married Mina-sensei is forced to play the most problematic sex toy in the school. Kana Kusakabe

I married my colleague, Professor Kaneda, retired, and started a family. However, while my husband was at work, he fell down the school stairs and hit his head and was hospitalized. In place of my husband, who was unable to work, I decided to return to work part-time. The academy has been devastated since a student transferred to it, and problem children are gathered in a special classroom and isolated. ……I was entrusted with that class and was raped by the school's number one problem child.
