My girlfriend and I went camping at a very secluded place. Matter a fact, in the 3 years we had been going there, we never saw one other person, until this night. We had been there all day fishing and swimming. It was getting later on and we decided to eat, when this car pulled up. Three guys and one girl got out. They asked if we minded they join us at our camp site. I didn't care, so they set up their tent. Only one.
We sat around the fire and drank and talked. Later on, one of the guys got up with the girl and they disappeared in the tent. Clearly we could hear them having sex. So I said to the one guy, they must be a couple. She says no, none of them are couples, she just likes to please then all. I called bullshit on him, but sure enough, a little while later, they returned and she took the other guy to the tent, and then finally the last guy.
We started talking about what happened and the girl likes to have sex, but doesn't want to screw just anyone, so she picked these three guys. I asked the last guy if he enjoyed fucking her pussy full of other guys cum. He said it wasn't bad, and was actually kind of arousing to fuck a cum filled pussy. The girl then asked if I wanted to see for myself. My girlfriend Instantly jumped up and said hell no. The girl calmly told her she got to have the three guys. We talked it over and agreed to do it. For the next few hours I spent the night fucking this girl while my girlfriend fucked these three guys.
