A solo performer, armed with a cock ring and eager anticipation, begins his session. His veiny cock throbs as he strokes it, the head swelling into a perfect mushroom shape. He squeezes his balls, feeling the pressure build. His hand moves faster, the friction intensifying. With a groan, he comes, his cock pulsing as streams of semen dribble out, leaving trails on his skin. He catches his breath, then starts again, his body responding to the taboo thrill of fertilized cum.
