The male mature slave is shackled to a bench, with his legs spread wide via a spreader bar. His ***** are tied with a rope, and metal rings have been fitted to both behind his ***** and behind the head of his defenseless ****. Watch his **** get longer and harder as more and more electricity adds to his suffering. Watch as his mistress pulls his shiny ***** up with the rope, and the head of his ***** swells. Listen to him scream and watch him jerk hard when his mistress turns the juice up all the way.
