My little girl has to wear big girl panties today! I know she is going to make a mess of herself, so I got her a special pair of plastic panties so I can see everything that happens. She tries so hard to hold it in and ends up pissing all over herself, filling her undies with pee until they can't hold anymore. She's so embarrassed, piss running down her legs and dripping all over the floor. What a mess! She's going to have to clean all that up!
