This video is a compilation of works submitted to the SM magazine "Mania Club". [The following is from the contributor, Sachiyo (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, have to deal with...I knew it was wrong, but I accepted his son's request and crossed the line...Scene 1-I was made to show off in public and urinated in my mouth so that I could be engraved in my heart that I was the bottom layer ●●.I forgot that I was a mother and felt that my spirit was collapsing.Scene 2-While I was made to cum many times with an electric massage machine with my hands behind my head, I finally leaked pee while wearing underwear.As a punishment, Mr. S urinated from her head with wet panties stuffed in her mouth.As it was, her whole body was tortured with a strong water flow of the shower, and finally she was submerged in the bathtub many times and received discipline of water torture.
