Mia was relaxing in the studio bed while waiting for the next shoot.  She didn't realize I was hiding in the closed.  As soon as she was totally relaxed, I snuck up and pulled her panties, gently, into her ass.  She didn't see me and casually picked the wedgie from her ass.  She was soon back to relaxing.  I did it again.  She started to get irritated at the continued wedgies, she didn't know why her panties kept crawling up her ass.  I do love my work.
