Isis is the sub driver from your hottest desires and little billy is the successful boy under her boot for the day. After she works him into a sweat doing manual labor in the Armory dungeon, she polishes his face into the filth before chaining him to a wall for a decent hammering.
'Are you a boy or a worm?!' she barks, her flog raining down on him as he wriggles on the ground like the invertebrate that she turns him into. The hammering and dehumanization pay off with a very super-fucking-hot boink from the nasty Domina, and tiny billy is more than well used when she eventually permits him to come.
