I have heard that this ballbusting slave can take quite the beating, but I want to be sure its not just a rumour. I have no time for lousy, weak slaves. I test him out, starting with hard kicks from behind, on all fours, then from standing. I also take the the time to step on his balls in my sexy platform thigh-high boots. I beat the slave's balls with hard knees and feet while explaining what I really want in a ballbusting slave: Sweat and tears! The harder the slave gets kicked, the more he moans, and the bigger his dick gets. This is exciting to me so I don't stop until he collapses against the floor. Then I make him lick my boots clean.
