This marks the third collaboration between Aya Shiomi and bondage mistress Kasumi Hourai, with their previous works having become instant classics. This time, the story is presented in a dramatic format, going beyond just erotic lesbian bondage to explore the complex psychology hidden beneath women's love for each other. Delving into the generational gap between an older, Showa-era woman (Kasumi) and a cool, Heisei-born girl (Aya), the narrative crosses the boundaries between romance and BDSM. During a heavy downpour, the two meet at a lesbian bar, where a drunken Aya is taken to Kasumi's apartment to wait out the rain—only to be immediately exposed to an intense lesbian session. Initially hesitant, Aya gradually surrenders to unknown pleasures, experiencing ecstasy and being drawn into Kasumi's abnormal world. The film depicts Aya bound in a red rose-filled bath, choked, humiliated, anally stimulated, and losing control with vibrators and electric massagers, climaxing repeatedly. Through this process, her true female masochist nature is awakened, and Kasumi becomes deeply obsessed with her. Their relationship eventually transforms into love, but Aya begins to feel burdened by Kasumi's intense affection and jealousy. After a year and a half of SM training, Aya evolves into a genuine extreme masochist, climaxing uncontrollably from single-tail whip sessions and even while tied before a Buddhist altar with burning candles. The love between these two women from different generations unfolds beautifully—and obscenely—through the world of BDSM.
