In the dimly lit room, a solo man, his cock adorned with a metal ring, begins his hardcore urethral sounding adventure. One by one, he slides nine steel balls into his urethra, each one stretching his member further than before. The sight of his engorged, veined cock, filled with metal, is a testament to his dedication to his kink. As he reaches the final ball, he lets out a guttural moan, his body trembling with a cocktail of intense sensations, pushing his limits to the edge.
