Today I decided to wear a sundress that was a little to short, as always I didn't wear anything under it. I need to pick up a few items for dinner. While in the store I was bending over picking a few cans from the bottom shelf. Not thinking anything of it I bent over at the waist as I was deciding what to buy. After weaving between two isles I noticed a man that was behind me a ways back but almost appeared to be following. A little more conscious of my surroundings I squatted down and grabbed a random package of food. Out of the corner of my eye I could see he was staring. I knew my dress was exposed my butt when I bent over, so I decided to leave my cart in place and walked closer to him. I stood and looked at the bottom shelf and faced my backside to him as I bent over to pick up something. I stayed like that for a few seconds and could see him staring at me. It felt so exciting to know he was able to see that I wasn't wearing any underwear. It made my day knowing his day just got better by exposing myself to him.
