Day 68 - For today’s edging training, master Kai instructed the muscle boy to put on all his edging equipment. The nipple clamps, cockring and butt plug will enhance the muscle boy’s training. The muscle boy got really horny and dumb really quickly. He was totally controlled by his cock and balls, just like a good muscle boy. To end his session, he has to punch his balls 100 times to bring his brain back online.
