You know what?
Since you are a little girl, a little princess, and you really need to go to the potty, we have to take precautions!
We can't have you wetting yourself and ruining your pretty little panties.
Let's put on some pull-ups! Grab two or three more panties and put them on over the ones you have.
If you don't have any more, then you need to stuff toilet paper or tissue down to make layers...make them nice and thick and padded.
Too bad we don't have hello kitty pull-ups for you :(
Oh my, this is turning me on so much!
