I am continuing My series of cruel experiments with My slave's body, and today I am experimenting on his balls. I have My slave tied up with his balls in a humbler and proceeds to torment his most sensitive region with her hands, a pinwheel, cane, and hot wax. My slave gets the full works! Of course, he is grateful for every second, and, luckily for him, I am pleased with My cruel experiment. What part of My slave's body will I experiment on next?
