The present wife does not do any work colleagues, but the Ex was a nympho, who fucked just about anyone who asked. She worked for a small engineering company, Owner and his co-owner wife (they were early 40's), 2 engineers one older(about40) one our age (we were early 20's), and a mid 30's draftsman. Her car was in the shop, so I dropped her off and picked her up while it was being fixed. When I dropped her off on Friday, noticed she was dressed a little sexier than normal. Mid-thigh leather skirt, white shirt with a white tube top, and heels, didn't really think much of it. At noon she called me to ask if I could come in about 4 to get her, they were closing a little early for the weekend. So, at 4 I go in the office and the owner's wife (very hot looking brunette) was at reception desk, she says I will take you back to the wife, just let me lock the door. We go down a short aisle to their conference room, her explaining they like to start weekends early and let their hair down on Friday's. We open a closed door and there is my naked wife, lying on a table, head off the edge sucking a fat cock, while one guy is eating her out, and 2 other guys kissing and playing with her nipples. The owner's wife explained normally that was her job, but they decided that my wife should enjoy the fun also. She kind of pushed me into the room and closed the door behind us, the wife taking the cock out of her mouth and smiled and went back to sucking the cock. The other 3 guys stood up and I was introduced to them, and they went back to work on her. The owner's wife spun me around and started kissing me, she was a woman in heat, lot of tongue action. Next thing we are taking each other's clothes off and I started fingering her shaved pussy. She sits me down in a chair and climbs on me reverse, sliding my dick in her, while we watch the action increase on the Ex. The older guy laid down on the table, had wife lube her ass and put his 6" in her while the owner climbed on top, putting his fat 8"in her pussy the other 2 were near her head, she is giving them the oral treatment, this went on with the guys changing places for well over an hour. In the meantime, I blew my load in Vivian's (owners' wife) pussy and was getting hard again watching all the action, she in turn going down on me getting me up again. We all kept up for another hour and then finished. Wife enjoyed her Friday's there, and this went on for over 2 years. The Ex got a substantial raise twice a year and used to go away on business trips with the owner, usually coming home with great stories of what happened. While she was with him, Vivian and I would get together and enjoy ourselves, was a great working relationship. Unfortunately, they sold their company to a larger firm and the fun stopped. The Ex left shortly after
