Urethra, the adventurous solo artist, delves into the world of sounding in this intimate, explicit exploration. With a 12mm sound, he gently pushes the metal rod into his urethra, feeling every millimeter as it glides in. His body responds, skin flushing, as he strokes his rock-hard cock in sync with the invasive pleasure. The camera zooms in, capturing the intense, graphic detail of the metal disappearing into his urethra, while Urethra's moans fill the room, building to a climax that leaves him gasping.
