This is a compilation of footage shot by Kaori (pseudonym) and her master, Motomiya (pseudonym), who met through the reader correspondence section of the SM magazine "Mania Club." Kaori has struggled since childhood to suppress intense masochistic desires, repeatedly engaging in self-degrading masturbation fueled by perverse fantasies. Her deepest wish finally came true when she pledged herself to Mr. Motomiya as a virgin anal-only sex slave. After seven years of rigorous training, she experienced a deeply traumatic and humiliating deflowering on her birthday. The act involved a grotesque strapon she purchased herself being inserted into her virgin pussy by a complete stranger—a sex worker she had just met—for the first time. This release includes shockingly erotic scenes following her deflowering, including an SM threesome with the sex worker and further humiliation such as being taunted with a cucumber. Please understand that this is an amateur submission video filmed by real-life BDSM enthusiasts, not a scripted or staged production like commercial adult videos, but rather an authentic, raw, and intensely lewd record of their experiences.
