My wife and I and our 4 kids went camping a couple years ago. We are in our thirty’s our kids are 11,9,6,5 my wife is beautiful and blonde and looks like she’s younger then her 38 , she’s works out a lot and people are shocked she has 4 kids, she has perfect to large tits for her size. We take a 5 day trip to this camp site we go a lot, it was packed the first day and night, the second night we were there, a another couple site up camp next to us, they had 5 kids and all about the same age as ours, the couple were Steve and tina, we are Troy and Tammy , all of us got alone like we were friends forever, the kids played as we all hang out. After the kids went to sleep we all had drinks, we had a great time, on our last day Steve rented a boat for 2 days. We all spent the day on the boat. It was great, Steve and Tina were about the same age as us, but Steve was the one that looked younger and was in great shape, Tina was over weight and had really small tits. I caught Steve looking at Tammy in her bikini on more then a couple times. And I saw Tammy looking at Steve and his muscles a time are too, because I too could lose some weight also. On our last night there and we all had many beers, Steve wanted to take the boat out just us adults, Tina said go ahead I’ll stay here with the kids you guys just go. Steve said pack a cooler let’s go!!! Tammy said I’ll stay here with you, Tina said don’t be silly you guys have fun !!! So off we went. It was just a little lake, we headed to a secluded cove, we all started drinking again. I said I have to take a piss and got up to jump out into the lake, when my wife grabbed my trunks and pulled them down, I just kicked then off and shouted skinny dip and I jumped in my wife quickly jumped in to and swim to me and she was nude as well, Steve said when in rome, and he stood up on the side of the boat and take his trunks down, the lights on the boat made it easy for us to see his huge cock as he jumped in.. after a minute or too my wife said she was going back to the boat . My wife stood and leaned on the rails of the boat, Steve said I’ll go get some drinks. I swim out a little farther from the boat, I heard my wife say she needed another beer, I saw Steve walk over and hand her a beer, I then saw him start to walk behind her, then he stopped. I then saw my wife bend over the rail and it looked like she pushed her ass into him, then I saw Steve look down and then I saw my wife moving her ass back and forth, I then saw a pair of hands cup her breasts and he started squeezing them, he then grabbed her hips and I could see he was fucking her hard from behind I could hear her moaning and telling him to fuck her harder I was I shock , I could move I just watched as they fucked in front of me . He grabbed her pony tail and pulled it back as he fucked her, he then said something and she got on her knees and he stroked his cock into my wife’s waiting mouth , she shallowed and sucked his cock dry. They got dressed and I got in the boat, and got dressed we didn’t say a word about it . We got back to camp he went to his tent and we went to ours, we got up had breakfast like we had done the whole week and we left, we never spoke about it again !!!!!
