Celebrity Wife Sachiko Trained by Her Son [Screaming and Beating Edition] Who's the JAV actress in this video? Amateur? Name revealed!

This work compiles various episodes submitted to the SM magazine "Mania Club." The contributor, Sachiko (pseudonym), candidly shares her experiences as a mother being trained by her son, Kou, as a "female slave●." Kou was an outstanding student—graduating from a top university and securing a job at a major corporation. He was expected to succeed his father as company president. However, he harbored a hidden side. Influenced by an older man, Mr. S, whom he met online, Kou developed SM tendencies, eventually beginning to see his own mother as a sexual object. Upon hearing this shocking confession, Sachiko was overwhelmed with despair and guilt. How much pain and inner turmoil must her diligent, brilliant son have endured? Ultimately, she gave in to his demands, crossing the line. In Scene 1, she undergoes training by urinating while standing in front of both S and Kou. Her heightened sensitivity is tested as she masturbates while pinching her own nipples, then continues to be used as a plaything. In Scene 2, her groin is stimulated with fingers and a vibrator, but she is denied orgasm. Unconsciously, she begins swaying her breasts, craving climax. The effects of the training become increasingly evident. In Scene 3, she is forced to change into a prostitute-like outfit that widely exposes her crotch and leaves her nipples fully visible. Blindfolded, gagged, with nose hooks, nipple vibrators, and clothespins clamped on her genital area, she endures escalating humiliation. As Mr. S declares, "This is the proper attire for an M slave●," he takes commemorative photos—creating an intensely shocking scene. In Scene 4, she undergoes the "mummy" bondage, wrapped tightly in plastic wrap until she cannot move. A vibrator is fixed against her groin, forcing continuous orgasm, while her mouth is sealed shut with wrap, making breathing difficult and her mind go blank. Yet, being treated like an object did not feel unpleasant—because she found joy in becoming the person her son desired, and in submitting to his training.
