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-The obsceneness of my female hole was tested while the upper body was bound with a rope.Even if I desperately try to endure it, I can't help but get a nasty pant voice.At that time, I was mercilessly beaten by Mr. S with a flat hand and a whip.At the end, my face was drooling and tears.Furthermore, I was tied up all over my body and beaten all over with clothespins while being whipped a lot.I'm sure my screams were echoing outside the room...Scene 2-As a reward for training hard, I was allowed to taste Mr. S's cock.When I was crazy about my pacifier, it gradually got harder and bigger, so I asked him to insert it into my wet female hole.Every time she was pistoned, she felt like she was going crazy with so much pleasure that she forgot Kou's existence and drowned in pleasure.
