Seifuku shoujo rezu chikan – Uzuku karada o hiwai na tetsuki de yamitsuki ni naru hodo binkan kaihatsu sarete… Ayame Tozaki Himari Kinoshita

A pure-hearted girl boards a women-only train car, unaware that a predatory lesbian lurks nearby. Without a voice to call for help, she's overwhelmed by fear and shame as her body begins to respond to the silent, obscene touch. Gradually, her sensitivity intensifies, and pleasure overtakes resistance. What begins as an assault spirals into addiction, as she finds herself craving the very contact she once feared.
