Her body is immobile from fear. She can't even call for help. On the train, Konatsu is confused by the hands crawling all over her body. She never thought that someone over 60 years old would be the target... Defenseless Konatsu is unable to resist and is made to climax, and is even taken to the station toilet where she is creampied... A few days have passed since then. It's an experience she should want to forget. Konatsu finds herself masturbating whenever she remembers that scene. She wants to experience that intense sensation again. A forbidden emotion is beginning to grow within Konatsu.
