To humiliate my slave, even more, I put him in a diaper that he has been wearing for 8 hours now. To make him aware of his position, I'll give him a jaw spreader and use him as my personal ashtray. He now kneels beside his mistress and I flick my hot ashes into his slave mouth. As a reward, he gets my delicious spit right into his filthy mouth. Always handy, if you have your property constantly available.
