Mountain Moments

Its the end of a full day of hiking. Me, my girlfriend and our two friends set up camp by the mountain lake. All of us are sweaty from the days activities, so to cool off we strip and head for a skinny dip. Its the first time me and my girlfriend have seen the other couple naked and we are both instantly turned on. A few minutes later the teasing starts, butt cheeks are squeezed and before we know it we're all kissing. Cooled off and excited we all get out of the lake and on the shore we fuck, side by side, doggy style whilst watching the sun set behind the mountains.
