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... Even though I knew it was wrong, I accepted my son's request and crossed the line... Scene 1 - T-kun was in the hotel room where Kou and S-san took me. T-kun is Kou's childhood friend, and I've known him since kindergarten. T-kun, who lost his mother at a young age, loved me like his real mother. When Kou told me, with eyes that could not hide his excitement, "Mom, you will be T's toy for the day," I realized that I was walking a path from which I could not turn back... I was made to hold my underwear in my mouth and perform an masturbation show in front of T-kun. Then, as a greeting, I had T-kun's semen fill my mouth with a blowjob. Scene 2 - S-san joined in and was tortured with pleasure using various sex toys. I was surprised at how much I could make. For being so shameless, T-kun poured hot wax on me as a punishment. Finally, I received semen from T-kun once more as an apology with oral service, and finally, a shower of pee calmed my burning body... Scene 3 - On this day, S-san trained me as a slave. I was ordered to masturbate in front of him, and after I came humiliatingly, S-san brought me to climax many times. To punish me for being too lewd, S-san showered pee on my head. Watching my mother being defiled, Kou, who was filming, had his eyes glaring with strange excitement. Scene 4 - The discipline of me, a bitch, became more intense. Long spankings, forced deep throat, enema punishment... I tried my best to serve his penis while enduring the pain in my stomach, but in the end, even the embarrassing liquid spurting from my asshole was filmed.
