Ballbusting training for a slave

Description: It's time for a daily ballbusting training for my slave. i want him to handle more and more pain, so he needs to get familiar with big pain in his balls. to prevent from covering his genitals with his hands, i chined them to the collar on his neck. i kick him while he is standing, on all fours and to additional plesure for me i tie a rope around his balls and cock, pull them and kick. it's an amazing pleasure for me, probably not for him, but he wants to be a better slave, so he has to lead a painful life. more ballbusting videos for you.
