Just Tights! (pantyhiose)

I used to work in a supermarket a couple of years back. Whenever I was working on night shifts I was used to seeing things a little out of the ordinary, but this one time I could not believe my luck! This woman was casually doing her shopping. She was dressed normally on top but at the bottom had on only sheer black tights(pantyhose)! No dress or skirt. I wasnt sure if she had knickers on as I wasnt close enough and anyway I only got a few glimpses, but it was a good night!
