...7:12am departure, platform 2, car 8, door 4. I am often molested by a man whose occupation and age I don't know. Even though I know I am not fit to be an educator, I still get on that train today... Ayaka used to be an ordinary, kind teacher. However, after being molested on the commuter train one day, her desire to be touched by a molester grows. The pleasure of being touched in secret, the tension of not being able to make a sound even when she feels it, the immoral act that is the opposite of her life as a well-behaved teacher - before she knows it, Ayaka's virtue falters and she turns into an immoral female teacher who waits for a molester on the commuter train every day.
