So we have a thread about the most unique places you have had sex which I would argue is different from the most amazing... So what are the best places? I will go first. I have a few contenders...
First is under the sky next to a high Sierra lake. This was no more than a few weeks after my first time so everything was new and exciting anyway. I was working for the summer for my best friend's family's ranch. It was with his older sister who was my first. We were never in a relationship but were super passionate fuck buddies. Me inexperienced and awkward at first but a quick learner under her playful guidance. Anyway a bear had been killing calves up at one of the summer pastures and she and were sent up there to camp out and guard them. It was just the two of us (something they never would have allowed if they thought we might be fucking) since my friend was recovering from a serious injury after getting thrown from a horse.
We set up camp next to this small lake fed by a small stream/spring water. There was a large meadow to one side of it and it was rocky on the other three sides and climbed steeply up a mountain opposite the meadow. It was kind of on a plateau so you could look over the valley below and many miles away see town. We camped on the granite rock area since the cattle avoided it. After a day of riding fences and setting up camp the first day we decided to take a swim. We stripped off and went skinny dipping. We swam and splashed each other and then she all of the sudden grabbed my dick under water. She started joking about shrinkage and saying she couldn't find it and stuff.

Hey it was fucking cold water. As she kept playing with it and I started playing with her tits while we started making out in chest deep water my shrinkage problem went away. She wrapped her legs around me and with the floatation of the water aiding the movement just kind of settled down onto me and we started a passionate fuck session. We had a blanket spread out on the rocks and it was getting super cold in the water so I walked out of the water with her still wrapped around me and making out. I lowered her onto the blanket and we barely missed a beat. I erupted a couple minutes later deep inside her. Right away she was sucking me hard again and we kept at it for several hours fucking, sucking, licking, kissing... until I was completely spent and it was starting to get dark. It was a super clear day with just a couple wispy clouds. I remember at one point hearing the screech of an eagle and looking up to see him soaring high above us. You could hear the slight breeze through the pine trees. You could see for miles and miles below us. The soft lapping of the water was relaxing. My words do not do it justice. At night, we could see all the stars and the milky way. We had a camp fire which we cooked over. We camped there for a magical six days fucking like bunnies until I finally shot that damn bear who's skin is now a rug on the floor in my den. It was kind of funny. It was nearing dusk when we heard the cattle making noise because of the bear. We were fooling around and I was wearing a shirt and socks but no pants. I stepped into my boots without taking time to put on my pants, grabbed my 30-30 Winchester that has been in my family since 1902 and ran towards the meadow bare ass. She was laughing because she said it was quite the sight.
Ironically, I have fucked my wife on that bear skin rug in front of the fireplace more than once. She has no idea the history of the week that I got the rug. She just knows it was a bear I shot protecting cattle. It makes it extra hot because the rug reminds me of that week.
I was going to share a couple others but I wrote a lot here. Maybe the others another time.
