In the dimly lit dungeon, the Anal Machine awaits, its mechanical arms quivering with anticipation. A willing sub, lubed and primed, takes his place, knees trembling as the machine's rigid, silicone-capped shaft slides into him. The machine's operator engages the controls, sending it into a rhythm of short, powerful strokes. The sub's cries echo off the stone walls as he's impaled again and again, his body tensing, ready to explode in a torrent of pent-up desire.
