My wife and I went hiking on a mountain overlooking our large city. We got to the top of the mountain and could see for miles and miles around us. We were along and my wife, without my suggestion, left the main part of the trail and found a rock outcropping. By the time I'd caught up with her she had already taken her top off and was sitting on a rock, just waiting for me to take a picture. I willingly obliged. What was an exciting topless photo shoot quickly turned into a fully naked shoot, all within eyesight of anyone that happened to look up. My wife even decided to walk the trail completely naked, and this wasn't some overgrown forest trail, but a trail within eyesight of millions of people if they just happened to look up.
It wasn't long before we were both laying on the hard rock outcropping and fucking under the bright southwest sun. a mountain top fuck fest at high noon is something we now recommend to everyone.
