Haha, no worries. Hmm, are you implying the treadmill added to a predicament in the stocks like this? Or specifically referring to another post with a different sub that was on the treadmill with his balls tethered to the front of the treadmill? If you're talking about combining the treadmill with the stocks, if that were possible, could probably make the rope really short or maybe just add a short bungee cord to the stocks so that he had to constantly move his feet while his head and hands and maybe even dick and balls were locked in the stocks. If dick and balls were locked in the cock stocks, no need for a rope or bungee. He wouldn't want to slack on moving his feet since his cock and balls aren't going with him if he gets behind. ;-)
