Cock and balls tied to treadmill with nipple clamps and hands cuffed

In this video I tied my cock and balls added wrist cuffs and binder clips to my nipples and attached my bound cock and balls to the bar of the treadmill and set the treadmill going to a speed of 3.5kmh they clipped the cuffs behind my back after 2.5 minutes I untied the rope from my cock and ball and attached it to my nipple clamps and set it going again and re clipped the wrist cuffs for a further 2.5 minutes with nothing to hold onto this was very difficult to keep from ripping the nipple clamps off or stretching my bound cock and balls out
