Isn't it such an adrenalin rush to expose your cunt in public where any stranger might see you being a very very dirty girl? I did this when I was a bit younger than you (early teens) and I still remember that an old man (old to me then but probably only about 40) told me I was a very dirty little girl and that dirty little girls grow up to be dirty sluts. And I rushed past him and went to the public toilets and wanked myself off whilst reliving the experience!
