Mistress Nikki's caged slave is about to have his urethra stuffed full of sounds. First, a nice chunky steel one to dilate his hole, and then an even thicker silicon sound which Nikki somehow manages to push in all the way to the hilt. The slave is overcome by the sensation of having his cock stuffed so fully and reaches a very quick orgasm with it in place – perfectly plugging him and preventing his cum from escaping.
