I can't tell you how many times I've requested that my wife tell me the stories of hooking up with her boss, while I jerk off. Sometimes I get her to tell me the stories while we are having sex, so I can finish. She did him in his office multiple times, his car (both parked on random streets and in the company parking lot), her car, her house, and two different hotel rooms during work trips (San Diego and Hawaii).
Oh, and also once during a corporate off-site in Mexico. They were playing "chicken" in the pool beforehand with another couple; my wife sitting on his shoulders while wearing a bikini. Then they went off to do shots together, and then to her hotel room. So I'm guessing the whole office knew that they were fucking by that point.
In addition to those physical hookups, there were many, many instances of phone sex, where her boss would send her photos of his dick, and get her to describe what she wanted to do to it, and what he should do to himself.
One of my favorite stories is that her boss got so used to her stripping down naked and crawling under his desk to suck, that he would actually take work calls while she blew him.
