My wife went with me to a trade show where a younger manufacturers rep was sent to work with me. After the show we all had dinner and went to the bar for drinks. We were all getting a little buzzed when she started quizzing him about his girlfriend. He blushed a little and said he hadn't had one for awhile, she said he must be lonely and a cute guy like him should have lots of girls. She is pretty hot, he said he wished he had one like her, she kicked me under the bar and I knew the night could get interesting. The conversation turned sexual, some flirting was going on and I suggested we go to our room for some beers and relax. We got to the room, got a beer and she went to change returning with her light robe on. After a couple beers the robe was getting lower and her tits were showing when she moved. We could tell he was stealing looks and was a little nervous. She asked if he liked what he saw, he blushed but said hell yes so she dropped it farther, got up and stumbled on top of hiim. Before long he had his hands on her tits, looked at me and I said go for it if he wanted. They started making out, I reached under her robe to find her pussy soaked, moved around to lick her pussy. She moved down, undid his pants and slid out a big soft cock. She sucked him a long time before he got hard and he must have been 8 or 9 inches long. She got up to climb on guiding it in slowly. She was wincing but eventually had all of his cock inside her and they fucked hard for about 10 minutes before he exploded inside her. She knows I like sloppy seconds, climbed off him and onto me dripping cum all over. She rode me while he watched until I came, she was so wet it didn't take long. We layed together for a half hour or so when she said she wanted more, went down and sucked him hard and he did her doggy while I watched. He came again, pulled out dripping both their fluids from his dick. As he got dressed he thanked us and said it was the best sex he ever had. After he left we fucked again before collapsing. The next morning he at breakfast he was a little sheepish, I told him last night was great and we could look forward to next year.
