Sachie 5 Who's the JAV actress in this video? Amateur? Name revealed!

This work compiles submissions published in the SM magazine "Mania Club," featuring real-life episodes based on the experiences of contributor Sachiko (pseudonym). Sachiko portrays herself as a hopeless, broken mother being trained as a "female slave●" by her own son, Kou. Kou was an outstanding student—graduating from a top university and securing a position at a major corporation—expected to eventually succeed his father. However, he harbored a hidden side. Influenced by an older man he met online, Kou developed sadomasochistic desires, eventually beginning to view his mother Sachiko as a woman to be dominated, trained, and humiliated. Upon receiving Kou's shocking confession, Sachiko is crushed by despair and tormented by guilt for failing to recognize her son's twisted psyche—something clearly born from deep inner turmoil. Nevertheless, she gives in to her son's demands, crossing an unforgivable line. In Scene 1, at Kou's request, a "rental training" session takes place where a stranger films Sachiko being disciplined in his absence. She is repeatedly punched in the lower abdomen, causing her to wet herself yet again. As punishment, she is forced into a dog-like position and subjected to relentless spanking and physical torment. In Scene 2, her nose is twisted with a hook, a gag stuffed in her mouth, and her genitals are brutally struck, exposing her to extreme pain and terror. The man laughs gleefully as Sachiko screams like a pig, her utter degradation vividly portrayed—a scene so degrading it deeply unsettles the viewer.
