Mine and my GFs first foursome experience was just a random thing that happened out of the blue one night in California.
My GF Sherrie and I had some friends of ours over one night, just drinking and having a good time listening to music and playing games. Sherrie was a very gorgeous girl, Brown hair to her shoulders, captivating blue eyes, a very nice set up C cup breasts and an ass you could bounce a quarter off of as the saying goes.
We had known Ron and Jessie for a while and used to drive to the beach every now and then to swim, tan and just have a good time. Jessie was knock out gorgeous. Very tanned body with a an ass like my gf. her legs were very tanned and very shapely with smaller tits then Sherries but still very firm. I would always catch myself glancing over at her, checking her out and and thinking to myself, man I would love to fuck that ass of hers.
Ron was more like me, more on the average size as far as looks went, but in shape just the same. Little did I know that a few weeks would go by and he would be fucking my girl and me finally getting to fuck Jessie.
So, back to that night. We had been drinking and playing games as I said and I don't remember just how exactly the topic came up but next thing I know we were talking about sex stuff and experiences we had and then the topic of swapping GF"s came up. It was a hot summer night so as always Jessie was wearing her typical tight shorts that barely covered that beautiful ass of hers. I had caught myself a few times checking her ass out whenever she walked by. And those legs of hers. So tan and sexy. I had noticed Ron taking glances Sherries way also from time to time whenever she got up to do something also so I guess it just seemed right.
