Nancy lets you out of the cage since you've been in there for several hours, but you are going to have to get used to being in there for hours on end. You brought this on yourself since you were so bad cleaning for her as a human slave that she had to turn you into her pet slave.  So now she is going to see how well you clean... with your tongue!  Start by cleaning her boots with your tongue and when you have done a thorough job on her boots she has you clean her shiny tights with your tongue to get them extra shiny, and don't forget to give extra attention to her crotch! When she feels you did a good enough job on the front, Nancy turns around and has you give her ass the attention it deserves! Shine up her ass with your tongue so you can see your reflection!  Once she feels you completed your task with your tongue, she reveals a bone gag to stick on your mouth, as she doesn't want to hear any of your yapping for a while.  Well now it's time to go back in your cage as she has to go train a new human slave.
