A curious, uncut man delves into the world of urethral sounding, his tight foreskin a barrier he's eager to breach. With a deep breath, he slides the plug into his urethra, the sensation intense and new. He takes his time, exploring his cock, his fingers tracing the sensitive ridge of his glans ring. As he begins to stroke, his mind races with the taboo nature of his act. The room fills with the sound of his heavy breathing, his moans echoing as he nears climax. With a final, shuddering breath, he releases, his cock pulsing as cum shoots from his urethra, the slow-motion camera capturing his intimate, explicit journey.
