I bind my thrall in rope and give her a stern caning when she disobeys my orders. If this babe tries to squirm I will switch to my trusty whip. On the days where this hottie is extra wicked I will even include a tongue clamp as part of her tit torment session. Slaves were put on this earth for us Masters (and Mistresses) to rule. I don't think of my actions as cruelty to my slaves. They WANT this kind of treatment. No one is forcing ’em to come to my dungeon. They are there of their own free will… they CRAVE this treatment. And I am only too happy to give it to them.
