[JUFE-574] Subjective Training: My Own Big-Titted Masturbation Support Pet: Teaching My Masochistic Student How to Help with Ejaculation, Riho Shishido (Censored)

The beautiful woman with a melting smile and big, plump breasts, Riho Shishido, makes her first appearance on Fitch! I've been training Riho, a beautiful secretary with big breasts. It all started when Riho was a student. I was her homeroom teacher at school, but Riho had a bad attitude, so as a form of discipline, I forcefully pushed her down and started training her! I trained the masochistic beauty as a pet for my own pleasure ejaculation, and taught her the secrets to ejaculating comfortably!
