In a private woods camping one night the wife and I were fucking doggy in front of the fire . As we both were getting close we hear a voice say " Hi guys " . We looked up to see a friend we both knew standing about 10 feet away . It was too late to stop and she erupted into a shuddering orgasm which triggered mine . She kept looking at him the whole time as she'd always had the hots for him . When we'd finished she got up and walked casually back to our tent . "Been here long " I asked . "Long enough " was his reply . "Want a beer ? " I asked. " Nah I better be going" he said . Wish he'd hung around, it might have gotten even more interesting .
