Ayaka Kawakita, A Female Teacher Who Has Become A Prisoner Of Train Molestation

...7:12 AM departure, platform 2, car 8, door 4. I am regularly molested by a man whose occupation and age I don't know. Even though I know I'm disqualified as an educator standing at the podium, I board that car again today... Ayaka lived as a kind and ordinary teacher you'd find anywhere. But one day, after being molested on the commuter train, she begins to nurture a desire to be touched by the molester. The pleasure that increases from being touched secretly, the tension of not being able to voice her feelings even when aroused, the immoral acts that stand in stark contrast to her upright teacher life—before she knows it, Ayaka's virtue wavers, and she transforms into an immoral female teacher who waits for the molester on her daily commuter train.
