In a private, intimate setting, an inexperienced enthusiast tentatively explores the taboo world of urethral sounding, capturing his first-time journey with a camera. With trembling hands, he carefully inserts a slender metal sound into his virgin urethra, gasping at the strange new sensations. His massive, uncut cock hardens as he gently pushes the toy deeper, his nerves gradually replaced by curiosity and arousal. He strokes his throbbing member, leaking precum, before cautiously removing the sound and capturing the moment of release.
