Delphine Stephenson, the mistress of the unknown, has created a masterpiece of sadomasochism. The scene unfolds in a cavernous room, the walls adorned with whips, chains, and other instruments of pleasure and pain. A woman, blindfolded and gagged, is suspended from the ceiling, her body swaying gently. Delphine, dressed in a corset and stockings, approaches. She traces the woman's curves with a feather tickler, then suddenly switches to a flogger, the tails lashing against the woman's skin, leaving it a beautiful shade of red. The woman's cries of pain and ecstasy fill the room, a melody to Delphine's symphony of sadism.
