First, thanks Heather for showing me this site and giving me the idea of telling what I did.
I went to a shop to get a new dress. In the changing room I stood there in just my bra and panties and caught site of myself in the mirror. I looked sexy. I thought about other girls in there with almost no clothes on and suddenly, I had to do it.
I reached into my panties and started to rub my clitty. I felt like a total slut standing there rubbing off. Then I had to get naked so I completely stripped. I know that most stores have video cameras to monitor shoplifters and that made it better. I hope the guy looking at it enjoyed himself. Soon I was almost there I leaned back against the wall and spread my legs. I pinched my nipple hard and it sent me over the edge. I can't remember cumming that hard ever. When I came down from it there was a wet patch on the floor. I think I peed, but I've heard that some girls 'squirt?' Maybe it was that. I decided to buy the dress, but I was so blown away by what I had done that I did not put my panties back on. Then I went to get some shoes. The girl assistant sat on one of those little stool things to measure my feet and I knew that if I let my knees move she would see that I had nothing on underneath so I did. She blushed up bright red, but couldnt take her eyes off my pussy. I made her go get me several different pairs of shoes. I swear to God I saw her panties several times and they were definitely wet by the time I left the shop. I went straight to the restroom and jilled off again.
I dont know why I am so horny lately, but I just can't seem to keep my hands off myself. I also think I like girls, like,sexually/ I'm back at school next week and I know there are several girls there who are lesbian. Who knows what will happen.
