The other day at the post office, I was waiting in line and had plenty of time to determine that the girl in front of me at the counter was wearing a thong. I could tell even without any sort of wardrobe malfunction. She was wearing a little pair of blue-green shorts, and the elastic edges of the thong where it disappeared into her ass-crack were discernable through the fabric. That, and her shorts-covered cheeks jiggled whenever she made the slightest movement, much more so than they would had they been panty-enclosed. So yeah, she was wearin' a thong. I wonder if anyone else noticed?
