In the dimly lit room, a lone figure, Fdselvagem, explores the intimate, forbidden realms of urethral sounding. With a glint in his eye, he prods his piss slit, inserting the cold, smooth metal sound deeper with each push. His groans fill the room as he stretches his urethra, each thrust sending waves of pleasure-pain coursing through his body. He twists and turns the sound, teasing his prostate, beads of sweat forming on his forehead. His solo session intensifies as he pushes the limits of his pleasure, each thrust bringing him closer to the edge.
