The dungeon is filled with the hum of the electro device and the master's low, commanding voice. The masked submissive, bound at the wrists and ankles, awaits the master's touch. The master teases the submissive's sensitive spots with the electro wand, drawing out gasps and shudders. He then picks up the metal sound, its smooth, cold surface sending a shiver down the submissive's spine. The master lubes it up, the smell of the lubricant mingling with the submissive's sweat. He presses the tip against the submissive's hole, the first shock of the electro current making the submissive's body clench. The master pushes in, the sound of the submissive's moans drowned out by the buzzing electro device.
