A few years ago my wife and I were working at an outdoor trade show and the factory rep was a cute younger guy and after the first day we cleaned up and went to the bar. My wife is hot and we have had a few encounters with other guys, we were getting a little buzzed and I finally said I was ready for bed, she said she wanted to stay so I headed for the room. I fell asleep and thought I heard her come in but didn't totally wake up until I heard another voice. I looked up and our rep was with her, they weren't feeling any pain and it was pretty obvious they were up to something. She said his roommate was sleeping so she invited him to party some more. I said why not and sat up. She grabbed us a beer and sat next to him on the bed. We were talking and he said I was a lucky guy to have such a hot wife, I laughed and said he hasn't seen anything yet. They were doing some flirting, getting pretty cozy and I got up to take a leak. When I came back they broke off a kiss and she had her hand on his crotch. He looked embarrassed but smiled and didn't bother to move her hand. I smiled back and said she usually gets what she wants and I was ok with it, she leaned back over to kiss him and before long they were making out and he managed to get her top off, was playing with her tits while she was unzipping his shorts. I decided to join in and slipped her shorts off, moved her so I could lick her pussy and it was soaked in no time. I heard her gasp and looked up to see she had his dick out and it was big. She was sucking him while I kept eating her but knew what she wanted and backed out of the way. She rolled over and said she wanted to get laid, he wasn't totally hard but she guided him to her and worked him in her pussy, kept at it until he relaxed and got into it. I watched them go at it until she worked him all the way in, wincing but enjoying it when he started tensing up and exploded, apologizing for not holding on longer. I knew she wanted more so I said move over, it's my turn and when he pulled out a big gob of jiz came with him. I didn't last long either it felt so good. We all passed out I guess and I woke up to them fucking again. She stayed in the room the next day while he and I worked the show, hungover and tired but each had a smile all day. The next night we took it easy, turned in early and he was gone early the next morning.
