About the sensual AV "Shiokawa Sensei's M Training Record," starring Undan Shiokawa, an M female teacher with a dynamic manner of speech and behavior, who depicts forbidden love being humiliated by her pupils. Undan Shiokawa plays the role of an M female teacher with great aplomb, demonstrating a dominatrix-like behavior that has earned her praise as a real masochistic woman. Her outdoor exposure play was particularly erotic and attractive, and I enjoyed it as if it were a private experience. The lack of pubic hair and the fact that she does not show her ass being hit is regrettable, but she was happy to be naughty in total. The film is full of vigor and destructive power, and we look forward to the next one.
