Nice. I can only imagine him in the corner trying to maneuver his body to get his dick to pull the ping pong ball away from the wall. Was it a nice tight hogtie you had him in? Or were you more generous in allowing him more freedom of movement, with his hands not tied so closely to his feet? I wonder what a fairly heavy weight tied to his balls would've done to slow him down a bit more, as his balls dragged it across the floor? *evil grin!*
