Trudie is masturbating herself on the couch, fingering her pussy with her little pink panties pulled to one side. She's thinking about all the times she pooped herself, and it's getting her more and more wet and turned on. The biggest turn on though is that she can feel a poop needing to come out!
This is how a lot of dirty pants pooping girls do it. They need to poop and there's no one at home - it turns them on and they have to play with themselves. The excitement builds to the point when they know they can't hold it any longer.
The sight of Trudie lying on her side on the couch with her finger in her mouth while a big mess fills her panties is to die for! Then, with a full warm load in her panties it's back to fingering herself and touching her nipples.
