Isis is the marionette driver from your finest desires and lil billy is the lucky man under her boot for the day. After she works him into a sweat doing manual labor in the Armory dungeon space, she polishes his face into the mud before chaining him to a wall for a decent beating.
'Are you a man or a worm?!' she barks, her lash raining down on him as he writhes on the ground like the invertebrate that she turns him into. The beating and humiliation pay off with a highly scorching bang from the horny Mistress, and tiny billy is more than well used when she eventually permits him to come.
