This clip should really have been called Mistress Vixen whipping, and ball busting, and smoking and having her boots worshipped as there is plenty of all three in this clip.
Mistress Vixen looks stunning in a full-length latex dress as she smokes towering above her naked cages slave who eagerly consumes her ash. The ashtray slave needs some obedience and quality of service improvement so that may be why he is caged next to a slave that is about to be beaten for some failure to please Mistress Vixen, or maybe just because she wants to beat him.
Having enjoyed a cigarette Mistress turns her attention to the slave standing naked in a set of head and arm stocks. Completely vulnerable and at Mistress Vixen's mercy. He gets well cropped as a warmup, then Mistress Vixen moves her attention to the balls just hanging there, they get a good busting. Ball busting and whipping alternate, obviously with his head the other side of the solid wooden stocks the wretched slave has no idea which is coming next, just knows it is always going to hurt!
Mistress Vixen enjoys another cigarette whilst her caged slave worships her boots and tends to his ashtray duties. A bit more rapid whipping of the second slave and Mistress Vixen is away to enjoy the rest of her day, whilst these two wait in fear of her return.
