Wife and female masochist "Mitsu" (pseudonym) undergoes intense SM training in this documentary-style release from Aesthetic Society (Tanbikai). Her face concealed beneath a full-head mask, she expresses pleasure even as her nose is tormented. Using a new device called the Skull Ghetto, her upper body is immobilized with a restraining pillory, while her big tits are tightly bound with rope. Unique implements such as a mouth gag, four-directional nose hooks, a bamboo ruler whip, and adhesive vibrators are combined to create an overwhelming mix of pleasure and fear. By hiding her expression under the mask, Mitsu finds satisfaction in concealing her true self, transforming from her ordinary daily persona into a depraved, submissive woman. This real-life recording captures the desires of an amateur, obedient, lustful, and emotionally vulnerable M woman undergoing extreme BDSM discipline.
