Ichika is suddenly molested on the school bus. I'm so scared of something that's the first time I can't do anything. However, at the same time, the fear of molestation changes into pleasure within Ichika. Even after I got home, I couldn't forget the sight of that time and masturbated fantasy. Perhaps the next day, she transforms into a high school girl who dresses up as if seducing a man herself and gets on the bus and wants to molest herself.
