This work features a video submitted to the editorial department of an SM magazine. The protagonist is Kikue, a company president's wife who has never been involved with any man other than her husband. She falls into a trap set by her younger sister, Mitsuko, and is captured by her brother-in-law Ryo, a sadomasochism enthusiast, ultimately becoming his sex slave. Her body is violated with a massive vibrator adapter forcibly inserted into her vagina, and as the training progresses, she can no longer endure even fist fucking. Even a small mistake, such as dropping the vibrator, results in punishment with a whip. The pain from the whipping is excruciating—so intense that Kikue breaks down in tears, unable to bear the torment. Her suffering is so extreme that it leaves viewers trembling in horror.
