Isis is the slave driver from your hottest dreams and little billy is the lucky guy under her boot for the day. After she works him into a sweat doing manual labor in the Armory basement, she grinds his face into the dirt before chaining him to a wall for a proper beating. Are you a man or a worm?! she barks, her whip raining down on him as he squirms on the ground like the invertebrate that she turns him into. The beating and humiliation pay off with a very hot fuck from the horny Mistress, and little billy is more than well used when she finally allows him to come.
