This video is a compilation of works submitted to the SM magazine "Mania Club". [From the contributor, Sachiyo (a pseudonym)] This is Sachiyo, a useless mother who is being trained as a female by her real son, Kou.Kou was a proud son who excelled in his studies and progressed from a prestigious university to a major company.Her future was to succeed her husband and lead many employees.Such a son is a mature sex, and he saw me as a "woman" as her biological mother.In addition, Kou's propensity for SM has sprouted under the influence of a middle-aged man he met on the Internet.At some point, Kou began to want to play with me as ●● and to ●●.When I received Kou's shocking confession, I was filled with despair and felt a strong sense of guilt for not being able to notice my precious son's distorted tendencies.How much trouble must Kou, who has such a serious personality, had to deal with...I knew it was wrong, but I accepted his son's request and crossed the line...Scene 1-On this day, Mr. S educated me as ●●.I was ordered to masturbate in front of her, and after that I was led to climax many times by Mr. S.To punish me for being so lewd, Mr. S poured pee on my head.Seeing her mother get dirty, Kou, who was filming with a camera, was glaring at his eyes with strange excitement.Scene 2-The discipline for me, a bitch, increased in intensity.Long spanking, deep throating, enema punishment...I endured the pain in my stomach and worked hard to serve the punchline, but at the end, I was filmed even with the embarrassing liquid that gushed out from the hole in my buttocks.
