It was a beautiful day. The sun was warm, the sky was blue and the trail and the trees were magnificent. I was working up a bit of sweat so I stopped for a rest near a cabin next to the trail. I took out my bottle of water and had a good long drink. Below where I was I could see two cars in front of the cabin below. All of a sudden my mouth dropped open. A naked woman came walking out to one of cars, opened the door and took out an overnight bag and walked back inside. I couldn't believe it! My curiosity got the better of me and I decided to see if I could get close enough to look inside. I made my way down to the cabin and was able to get to a point where I could see into the living room.
I was elevated a little from the window and in some dense trees so I didn't think I could be seen. I had a great view and what I saw instantly made my cock as hard as a rock. There were 4 people in the room, 2 men and 2 women, all naked. One of the women seemed to be saying something to the two men who then proceeded to get on the floor in a 69 and take each other's cocks in their mouths. My shorts were undone and my hand was sliding up and down my hard cock. I had lately been having fantasies about sucking another guy's cock. I had almost done it a few years ago when I was involved in a MFM threesome. Both women were on the couch playing with themselves. The two men seemed to be really going at it. All of a sudden the one on top pulled away as a huge spurt of cum erupted from the man on the bottom. One of the women stood up and seemed to be cheering.
Maybe they were having a contest. I was very close to cumming myself but before I did the man who had been on the bottom got on all fours, and the other man got into position behind him. One of the women crawled in front of him and he bent his head down into her pussy. The other man was directly behind him and I watched as his cock approached his ass and began to enter him. I could see his cock going in and out of his ass. I let my shorts drop completely and inserted a finger in my own ass. I was in heaven. I imagined that it was my ass being fucked. My cock was slick with precum. I licked two of my fingers of my other hand and inserted them in my ass. I was mesmerized as I watched the two men fucking. I could feel my orgasm coming and all of a sudden the cum flew out of my cock and landed about 4 feet away. I nearly fell over but managed to grab onto a tree and steady myself. It had been one of the most intense orgasms I had ever had.
I thought I had seen everything but apparently not. I refocused my attention on the window. One of the women had a huge strap-on dildo; it looked like it was about 12 inches long. She knelt behind the man on the floor and slowly inserted the dildo into his ass. My cock was getting hard again. I have been fucked in the ass with a strap-on dildo several times and loved it. It is probably why I got so turned on watching the two men. I think I was ready to try the "real" thing. The woman continued to fuck the man with her dildo for about five minutes. I could see her reach around with her man and begin to stroke the man's cock up and down. It didn't take long for him to come and they collapsed on the floor in a heap.
I was building up to my second orgasm when all of a sudden I lost my footing and went tumbling down the hill. This time I couldn't catch myself and with my shorts and underwear around my ankles I went head over heels until I crashed into the wall of the cabin. While I was making sure I hadn't broken anything or damaged the family jewels one of the men and one of the women came out the door onto the deck. I must have looked pretty funny, shorts and underwear still around my ankles, leaves and underbrush all over me and a sheepish grin on my face. The two of them looked at me and then started to laugh. The woman, said, "I'm sorry, we shouldn't have been laughing but you do look kind of funny like that. Are you okay?"
