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, have to deal with...I knew it was wrong, but I accepted his son's request and crossed the line...Scene 1-There was no Kou on this day. He said that he hoped, "I want you to take a picture of my girlfriend's mother being trained without me." In the world of SM, it is said to be "rental training".A man I met for the first time hit me in the lower abdomen many times, and I leaked again.I was relentlessly spanked in dog-like clothes as atonement for my poor behavior.Scene 2 - A hook distorted his nose and a gag was placed in his mouth.In that state, if the local area is beaten persistently, a pig-like scream will leak out of the mouth.The whole body was attacked with clothespins and pain was given to the body thoroughly.I cried because of the fear and pain, but seeing my miserable appearance, the man smiled happily.
