This dress makes me think of the time I had sex in the park with my dress draped over both of us for cover.  We started off just goofing around.  I was sitting on top of him.  I could feel him get hard.  I started griding on him and then I unbuttoned his jeans and pulled them down to his thighs.  Just thinking about it makes me horny.  People walked or ran by from time to time and no one was the wiser.  It was very exciting.  One of my best orgasms ever.
