Her homeroom teacher, Natsuki-sensei, is a rude teacher who constantly confronts her. One day, I witnessed Natsuki-sensei being molested on the train. Moreover, it didn't seem like he hated it. I secretly filmed it with my smartphone, and the next day, I showed the video to my girlfriend Natsuki-sensei, threatened her, and forced her to drink her aphrodisiac. She started to feel like it would be interesting to forcefully fuck her like that.
