This work focuses on a particular female with very specific tastes: her name is Ryo. I first met her during a shoot for the well-known bondage photography website "Norio Sugiura Kinbaku Zanshiki." She had voluntarily applied to participate. At that time, the bondage boom had not yet fully taken off, and it was rare for women to apply by themselves. She appeared quiet and polite, clearly nervous, yet her sensitivity toward ropes and masochism was incredibly intense—so much so that it astonished everyone present. Since adolescence, she had been deeply interested in BDSM, passionately reading SM magazines and actively exploring domestic and international fetish websites. Her knowledge ranked among the deepest I've encountered among female enthusiasts. Around the same time, I came across her in a submission for an SM magazine, where she was surrounded by men, engulfing penises with a melting, lustful expression that deeply shocked me. Intrigued, I invited her to model for me. That shoot, which became the cover of this release, featured her first experience with Buddhist altar candle torture. Suspended and fitted with a nose hook, she endured scalding hot wax, emitting sweet moans and convulsing with erotic spasms that captivated all who watched. I invited her for several subsequent shoots and received additional submissions. Her masochism has only deepened over time, and this work compiles the evolution of her transformation.
