You decide to try on some more shoes

You say "Sorry if I embarrassed you. I just couldn't help myself, haha. I really do need to find a pair of shoes. Let me see what else you've got."

You go back over and sit down. As you do the friction from the vinyl back of the chair causes you sundress to pull up high enough for you to feel the cool seat on your bare ass. You notice a guy standing near the store entrance staring at your exposed legs. You wonder how long he's been there watching. You pretend not to notice him. You don't even bother to adjust your dress as the sales guy sits down in front of you.
