Wife with trade show friend.
A couple years ago I was working an out of town trade show, my wife was with me and a younger rep was sent to help me. After the show we had dinner and drinks together, went to our room and my wife thought our friend was lonely, went to his room and fucked him returning to tell me he had the biggest cock she ever had, then I got great sloppy seconds. The next year, same thing except we invited him to our room for more drinks after dinner. We talked about him not having a current girlfriend and brought up the year before. He was embarassed not knowing that I knew but admitted he had a great time. My wife said her too and asked if he was up for some fun. He was sheepish but she leaned over to kiss him and things started. They were making out, she undid her to so her tits popped out and found his mouth, I slipped her pants off and started playing with her pussy and licking her. She was soaked in no time, started rubbing his pants and moved down to undo them while I was behind eating her out. She wasn't kidding, he was hung, and she sucked him til he was rock hard. I knew she was ready and backed off so she could get on top to take him in. It was awesome watching her face as she eased him inside her, and couldn't believe she worked his whole cock inside her. I sat back and watched as she fucked him for about ten minutes, cumming at least 3 times before he exploded inside her. I laid down, she lifted off him dripping cum and slid onto me. Even though she was soaked and stretched out I didn't last long I was so horny. We all collapsed together, fell asleep, and I woke up to him fucking her slow right next to me for a long time before he came again, collapsing on top of her. He got up, thanked us, tucked his dick in his pants and left. What a night.
