After reading the stories that others have posted, I think our experience qualifies as worthy to be written down also... this is a true story and it was the first time anything like this ever happened to us, even though we have been trying... My wife and I decided at the last moment to take off for a weekend camping trip to a remote area that we had been to once before, looking for rocks and gems. The weather forecast called for rain but that doesn't bother us as it actually helps to see the color in the stones. Before we got to our destination it started to drizzle a little bit so we knew we were going to be pretty much by ourselves at the campsite. When we arrived, we were surprised that the only other person we saw in the area had a motorcycle for transportation and was staying in a tent under a big juniper tree (we found out later he was a college student and was doing a study and mapping the area for a class project). we were going to be staying in our enclosed trailer that we haul our quads in, so it would be dry and have plenty of room to move around in. (we unload the quads) We Had a queen mattress that we stowed against the wall that we made into a nice comfy bed. After our introductions, I offered the other camper a beer, which he was grateful for as he came in packing pretty light, and after visiting for a while it really started raining, so we went back to our trailer and he went into his tent. We ate dinner and went to bed about 9. We fell asleep listening to the rain on the aluminum roof of the trailer, then around 11pm we heard the neighbor camper asking if we were still awake, (I was now). Then before I answered he knocked on the door. I got up and opened the door and asked what I could do for him... he was wet completely thru his clothes and he was wondering if he could stay in our pickup for the night. I said to come in the trailer and ill would get him some dry clothes to change into. My wife was still under the covers... I thought about it and the kid was not going to survive the night out there and we didn't have any extra covers, and I didn't want him staying in the truck and having the engine running for heat, so I asked my wife what she thought about letting him sleep under the covers with us. She said that should be ok. We all got in our toasty warm bed and I was on the outer edge and she snuggled up tight to me so he would have plenty of room, over half of the bed. And we all went to sleep... Sometime later I woke up and my wife was still snuggled tight to me, but I felt a slow rhythm motion that continued for a while but it didn't take long to figure out he was up against my wife and was grinding on her ever so slightly. I wasn't sure if she was awake or not, but the thought of it was arousing me. I didn't move or do anything and in a few minutes she moved and rolled away from me a little bit and the motion stopped. Then it started up again only different and I could feel her moving... I could only guess that she had rolled over and was now slowly stroking his cock with her hand and not wanting to wake me up. I was almost ready to cum thinking about her hand wrapped around this kid's hard cock... This guy was probably 24 and nice looking with a very pleasant personality and my wife is 46. She is 5'2", very good looking and has a great figure with firm medium sized tits. And she has a healthy sex drive. I am 50, 6'1" and also in good shape as we hike a lot and are outdoors people in general I am not overly long at 6", but it gets hard and extremely thick... and our sex life is great as we are both open minded and like sharing our fantasies, watching dirty movies and trying new toys. We have fantasized about a threesome and tried to make it happen but it always seemed forced or something... it just never happened. (Too many boorish or overbearing guys out there. Crude and rude is another description of a lot of the men you meet when trying to make something like this happen. We don't want someone like that). We are both very bi-curious and have always hoped we could connect with another couple. But after all the trying, something was happening now without trying. Finally, she rolled away from me and was now fully facing him and the action picked up. More motion and heavier breathing. I didn't know what to do, I was still acting like I was asleep, but I was excited beyond belief. Finally I moved a little and when I did, all the motion stopped and it got quiet. When it started again, I rolled over to face my wife's back and pretended to be still sound asleep... in a few minutes I slowly stuck my hard-on up against her crack... surly she had to know by now that I was awake. But he didn't know it! The motion started up again and a bit more now... then I started slowly humping on her like he did to get this all started. I gently moved my hand up on her arm and felt the motion of it playing with his cock, and then followed it down to where her hand was. I could tell by her motions that he had a nice long cock and she was working it pretty good now. I was still sliding my meat up and down her ass crack. Then I slowly worked my way back up her arm and then reached for her tits. And found a hand already there. He withdrew his quickly and didn't move, but my wife was now working his shaft harder than ever. I pulled her butt around so I could bury my hard cock in her pussy, and when I did this she bent forward and started sucking him. She had an orgasm within 30 seconds... There is no doubt now that everyone was awake and enjoying themselves. It was pitch black in the trailer, no light whatsoever, and no one had spoken a word. Then she pulled away from me and turned around and said "stick it in me" with her ass towards him. And she started sucking on me. He was up on his knees fucking her hard. She had my dick in her mouth and every thrust he gave her with his cock. I got just as good from her mouth... I knew I wasn't going to last long and in about 3 minutes I came hard and she swallowed... and she kept sucking me even after I went soft and he was still pounding her. Soon the rhythm picked up and he was grunting and my cock got instantly hard again knowing he was squirting a load deep inside my wife. Then she turned around and let me fuck her while she worked him over again with her mouth. Then we all fell asleep. In the morning I was woken up by the motion on the bed again... this time he was on top of her going at it and she was lying face down on her belly... I had to get up and pee. When I got back they had the covers off and I could see he had a very nice cock he was fucking her with, at least 8.5 or 9 inches. It was a lot longer than my 6 inches but not as thick... soon they both came and he rolled off of her... by this time I was making coffee. They cleaned up and got dressed and we had coffee, then she made breakfast. The weather was a little better in the morning and he had work to do and we had rocks to find, so we went our separate ways, her and I talked about the experience all day and decided we would invite him back that evening. When we got in about 4pm he was already at his site with a fire going so I got a couple beers and went and visited with him while she made dinner. I asked him if he wanted to join us for dinner and he said sure, so while I got up to go pee I asked him to go over and get a couple more beers for us from the trailer... and see what she was fixing us for dinner. After 15 minutes he still didn't come back... so I went over to see where my beer was and as I approached the trailer I could hear it rocking on the springs. I didn't want to interrupt her fun so I stayed away, but I did walk past the open door and saw they were hard at it again. She was on her back on the mattress with just her pants off, and he had his pants down around his knees and her legs were up over his shoulders... they didn't see me. I got so hard I forgot about the beer and went around the trailer and jacked off. In a little bit he came out with the beer. He said she distracted him for a few minutes. I said yea, I figured that out. We had a nice dinner outside and another beer and we had a fire going at our site by this time so we hung out, flirted and had a fun time. By this time it was about 6:30pm and in a little while she went over and sat by him... then she just reached out and opened his fly and pulled his cock out and jacked it and played with it in front of me in the daylight. Of course I was hard again. She knows I am curious about another man's cock... and I am not sure if she was teasing me with it or just letting me see how nice it was... either way I wanted to feel it in my hand and to taste it but I didn't know how he would react. I was so hard it almost hurt. But we just talked about stuff; work, play, fishing, just conversation while she massaged his meat and sucking it clean of precum every so often. Then she said she was going to go clean the trailer and she was going to get ready for bed. We stayed out by the fire and in a while I asked him if he needed a place to stay tonight, he said that it would be nice because his sleeping bag was still wet. We went in and my wife was already in bed, so we got cleaned up and crawled in too. She was facing me and it didn't take long and he was fucking her again from behind while lying on his side, as was she. I worked my hand down between her legs and got to feel his big dick sliding in and out of her. I was about as turned on at that moment as I have ever been in my entire life, before or since. She and I were kissing and it was intense. I absolutely love and adore my wife and the feeling I got by being able to share an experience like this with her is indescribable. It's a feeling of closeness that I've never felt before. We were in this together completely and solely for the sake of pleasure. After they both came again I was still horny and I wanted to see what it was like to lick her after someone else had his hard cock in her... so I whispered in her ear and she said she cleaned up good before bed and that she would like it too... Her pussy was hot, steaming... and wet... and once I got settled in I couldn't get enough. I couldn't tell his jizm from her wetness, but it was very wet and all good. It surprised me that I couldn't tell, but after cumming so much in the past 24 hours he probably didn't have much left to squirt. I loved licking her hot, swollen, freshly fucked pussy with a load of cum in it. I cleaned her up and then it was my turn to fuck her. It took about 2 minutes which was good for her because she was getting sore from all the fucking she had gotten from his long dick, and with my short fat one it stretched her sore pussy beyond comfortable limits. We all fell asleep and in the morning she gave him a good blowjob, we had breakfast and then we packed up and left. We talk about it all the time and want to re-live it. We wish it was easier to find the right guy for this type of fun. Maybe someday.
