My wife and I have had a few threesomes with guys we knew and I teased her about wanting to fuck a guy with a big cock. I’m average I guess at 6 inches and the guys we were with were similar give or take as were the guys she had before me or smaller. She said it didn’t matter so maybe it was my fantasy. We were in our mid thirties and in good shape and were working a trade show with a single factory rep in his twenties. It was apparent that he had a nice package and that night while we were getting ready for dinner she aaked if I noticed. After dinner and drinks we were getting a little buzzed and I asked him to our room for a few beers. She smiled and up we went, once in the room she changed into a a teeshirt, we drank and talked and she asked if he had a girlfriend, he said no so she asked if he got lonely. We knew where it was going, he said I was a lucky guy and before long she was practically sitting on his lap. He was squirming a little not knowing what to do, she smiled and said she was horny. He blushed and said he sure as well waa which was all she needed and off came her shirt, she straddled him with her tits in his face. He looked at me and I shrugged and said she usually gets what she wants. She started kissing him and worked down to undo his pants pulling his cock out which was bigger than any she had before. She was sucking him, he was having a hard time getting hard and I worked her panties off and started licking her pussy. By the time she had her first orgasm he was getting hard and was at least 8 inches, she said she wanted him inside, he slid up and she mounted him. She gasped a little and e entually worked him in. They had sex in a few positions while I tried to get sucked, finally he had her on his back pouring it to her and exploded. When he pulled out cum was oozing out and I slid into her soaked stretched pussy while she licked him clean. After one more beer he got dressed and left. She admitted it was great sex but didn’t want a big dick all the time. We were at the same show a year later and repeated but alot more relaxed
