Wife With Younger Guy

A few years ago friends of our's nephew Brad lived in another city but flew home frequently and hung out with us. He was a fun guy, ex marine and worked as an airline mechanic so could fly free when he could get off. It wasn't unusual for him to hit town on Friday and have a date for the weekend. He was a good looking guy in good shape and got along with women. One particular weekend he was alone, we all met Friday night for a few beers and were going water skiing Saturday. We met at the boat dock Saturday morning and 5 of us spent the day on the water. When Brad took his turn at skiing he had a great body and was clear that his package was impressive and I could tell that my wife noticed. We took the party to our house, ordered pizza and beer was flowing. Finally our friends were ready to take off and nephew Brad wanted to stay, we said it was fine and we would return him in the morning. We were having fun, getting pretty buzzed and finally I was ready to quit, my wife said go ahead, I'll be in. She has had fun with other guys we know which was all good and I thought there might be chemistry tonight also. Brad was about 10 years younger but my wife is in great shape. I left them on the deck and went to bed waking up to hear them going into the spare bedroom. Awake then I was intent on hearing what was happening, it was obvious that they were having sex and she wasn't quiet, lots of heavy moaning and at least 3 orgasms that I could hear. Finally I heard him say Oh Shit, I'm cumming and she said don't stop and she came again. They were quiet for awhile and she came to bed. I was wide awake and horny so I made her tell me about it She said she pretended to fall into him on the deck while handing him a drink, grabbed his crotch and they started kissing and she made her way down to find out he had a big cock and gave him a blowjob. He didn't last long, she said she was disappointed and he said don't worry, I can go again which is when they came in the house. When he entered her she had a hard time taking him but adjusted and he lasted a long time the second time. I was horny and had to have her, her pussy was stretched out and soaked when I entered but it felt great. The next morning I met Brad coming out of the bathroom naked, he said sorry but I can't find my underwear. I looked outside and they were on the deck, he blushed, I said don't worry about it, fun night? He said wow, was it. We all got dressed, had breakfast and took him back.
