Tokyo Train Girls: Private Lessons(揺れる電車の中で　女教師の淫らなアルバイト)

New teacher Chihiro has been on the job for three months. She does her job with great enthusiasm, but she has a secret that nobody must know. As a student, she accumulated debt in order to keep up with her well-to-do friends. She can’t pay it back on the wages of a teacher so she started working part-time as a Chat-Lady. In front of a web camera that hides her face, she shakes her breasts and hips. By chance, her student, Kazuaki discovers the web site.
