It all started one night at a party for a friend of mine.my girlfriend and I had been playing with each other all day so when a group of us went out clubbing it was a chance for her to tease me, needless to say after a couple of hours of her grinding her gorgeous body against meI was ready to take the party home.We all piled into a few taxis and we scored one by ourselves, no sooner had we started moving and she had my cock out and in her mouth.This went on until we got home where everyone was already dancing and drinking. I went to the toilet and when i came out my girlfriend jumped me in the bathroom, pulling my trousers down and grinding her already juicy pussy on my cock before she turned around and begged me to fuck her up against the wall, which of course i did! We did a sex tour of the bathroom ending in some vigorous doggy over the vanity.When we had finished we noticed the door had swung open a bit and sitting in the hall were about five friends clapping and cheering our efforts.It was kinda embarrasing at the time but it was some of the wildest sex i have ever had and we still like the bathroom
