An erotic story breaking new boundaries, fusing lesbian and BDSM themes! Kasumi, a female company president, has a deeply obsessive personality, passionate about lesbianism, bondage, and SM. She invites her newly hired employee, Aya, to her home and begins tight bondage training to satisfy her overwhelming desire for domination. Suspended in midair, Aya endures fierce whipping and, unable to resist, climaxes intensely. As the relentless whipping continues, she loses control and urinates, reaching a state of euphoric ecstasy. Next, Kasumi leads her into a traditional Japanese room, beginning a new session with Aya in a thin undergarment. Her legs are bound and she is hung once more, then struck repeatedly with a shoe horn. Lowered onto the tatami floor, her entire body is tormented with candle wax, culminating in a brutal fist fuck that leaves Aya writhing in overwhelming pleasure. The ultimate pinnacle of SM is achieved here!
