Bound at the wrists and ankles, the soloboy presents his rigid cock to the camera. His eyes dart to the urethral sounds laid out beside him. He knows the drill. Picking up the smallest, he lubes it up and, with a deep breath, inserts it. His body shudders as it slides in, his cock throbbing in response. One by one, he ups the ante, each sound larger than the last, his urethra stretched to its limit, his moans filling the room as he pushes his limits in this solitary, intense ritual.
