N0550 Miyu Arimori is trained from a shy honor student into a semen-hungry slut

Miyu Arimori, a fair and modest honor student with little sexual experience, is called after school by a teacher who likes young women. He kisses her, fingers her, and makes her suck his cock. She refuses at first, but is forced. By the end of repeated vaginal cum shots, her sensitivity grows and she is transfigured into a slut who wants semen.
