My girlfriend and I have been dating for about four months but all we've ever done was make out and fondle each other. We aren't usually very crazy but we had a little to drink and we decided to go skinny dipping with a couple of people. So we found ourselves sneaking into the pool at 2 am in the morning with 2 other guys and 1 other girl. It was really weird taking off all my clothes in front of other people. My girlfriend shyly removed her bra and panties and it was actually the first time I saw her completely naked and she was gorgeous. Everyone else actually got naked and we were all checking each other out. All the guys were getting erect, and I saw one guy had an enormous penis while mine is about seven, and the other guy was average, and both my girlfriend and the other girl rubbed their breasts and jumped in first. I was so turned on. I made out with my girl in the pool and put my dick in her pussy and slowly rubbed her clit and then fucked her. I knew all the other people in the pool were watching but it was dark, and I came inside of her, and she also came later.
