ACZ-019 Celebrity wife Sachiyo trained by her son [Service Training Edition]

This video is a compilation of works submitted to the SM magazine "Mania Club." [From the submitter, Sachiyo (pseudonym)] Sachiyo is a hopeless mother who is being trained as a female slave by her own son, Kou. Kou was an excellent student and was a proud son who went on to a major company from a top university. He was in a position to take over her husband's position and lead many employees. But this son was a pervert and saw me, his real mother, as a "woman." Furthermore, Kou had developed a sadistic SM tendency due to the influence of a middle-aged man, Mr. S, whom he met online. Before he knew it, Kou had begun to want to play with me as a slave and violate me. When I received Kou's shocking confession, I was overcome with despair and felt a strong sense of guilt for not being able to notice my precious son's twisted sexual tendency. I wonder how much Kou, who has such a serious personality, must have suffered... I knew it was wrong, but I accepted my son's request and crossed the line... Scene 1 - Kou was not there that day. He said he wanted me to take a picture of my mother being trained when he was not there. In the world of SM, it is called "rental training". I was hit in the lower abdomen many times by a man I met for the first time, and I wet myself again. As a punishment for my mistake, I was spanked relentlessly while dressed like a dog. Scene 2 - My nose was distorted with a hook and a gag was put in my mouth. When I was beaten persistently in that state, I screamed like a pig. My whole body was tortured with clothespins and my body was thoroughly in pain. I cried from fear and pain, but the man laughed happily at my miserable state... Scene 3 - I was tested on "service", the most important duty of a slave. She tried her best to run her tongue over the man's nipples, cock, scrotum, and anus, but she couldn't satisfy him, so she was forced to lie on the floor and receive a pee shower from S and the man... Scene 4 - They move to the bathroom and she is given an enema, and her service continues. While giving him a blowjob, she can no longer bear the pain in her stomach, and finally leaks dirty-colored juice from her asshole... In the end, she couldn't make him cum with her mouth, so she had to use her hole to satisfy him.
