All started with a Promotion

I work for very large international company and have since I was recruited straight for university. So, I got promoted over the years and then I got promoted again that is how the story started. At 36 and single I was doing great career wise and hadn't put much effort into my personal life. But with the promotion had just taken up I got a personal assistant. I wasn't really interested in an assistant but had to have one I was told. I looked about the available people, none took my interest. Normally younger PAs were the norm, and it wasn't my idea. I selected a 54-year-old woman as my PA as she seemed to be the quiet type. By which I mean seen and not heard, but she was easy on the eye even at her age. I didn't expect too much for having an assistant, but we clicked. She was soon very useful to me; she knew her way around the offices and help me complete tasks quicker. I was quite happy with her as my assistant, except she lived a fair way away from the offices. She was trying to find something closer and wasn't having muck luck. Working late may it hard for her to home or come in earlier if needed. After a bit of flooding that caused her to stay home, and I had to do everything myself. I realized how essential she was to my work. But I couldn't magical up an apartment she could afford, but I had an apartment provided by the company. It wasn't huge but it had 2 bedrooms and so as more rain was forecasted. I suggested she move in with me till she found her own place. She accepted and nothing happened, excepted she cooked, and I lived off take outs and she is a very good cook. So, we quickly came an agreement, she cooked the meals, and I bought the groceries. Then an apartment came up and I thought she would take it, but she was delayed and miss it. I found myself happy she had missed out; I made a decision I asked her to stay fulltime with me instead of finding her own place. She agreed as it was a pain trying to find a suitable place to live and we got on very well. Then there was a large problem with a project in the next state it was behind, and it was mostly due to flooding and muddy roads. I was dispatched to bring it up to date and would stay as long as needed. Of course, my PA came along with me and only a motel available to stay in. We got a room together with two beds, we were there 5 weeks and finally returned to our apartment. The first week nothing happened between us as we were too busy working to think about anything else, but the jobsite closed on the first weekend due lack of parts and materials also delayed by the flooding. So, we were alone in a motel room not much bigger than my apartment bedroom. The Saturday night we had dinner together as normal for us and then a few drinks to help pass the time. Not drunk, but in a very good mood you could say we got back to our room and ended up in bed fucking. Fucked again in the morning and we kept sleeping together after that. Neither of us were married or in any relationship either. On returning home she moved in my room after our return and fucked regularly. I had done well as usual for me and met the performance level to get promoted again. Which I accepted and we headed for the head offices and my new position. My PA came too, we were a team and why try and find another. But that's not reason I bought her with me. It didn't enter my mind to replace her is the real reason. A bigger apartment and office along with a personal secretary, who I had to hire myself. But I decided to let my PA find my secretary instead, she did, and I got a 30-year-old single girl and not in any relationship and had been raised in state care (orphan). She had the same problem my PA had lived a long way away from the head office building. My PA solution to have her move in with us, we had 3 bedrooms and 2 were connected by a Jack and Jill bathroom and the third had its own bathroom. But my PA had big ideas for our new team member. She saw the secretary as a wife for me and was going to play cupid. First, she seduced the secretary herself and after succeeding at that had her join us in a threesome. That is how things are now 5 years later I live with my PA and secretary, who is also my wife of 15 months and is 7 months pregnant. I'm still fucking my PA and my wife; it works for us, and I can't see why to change it after all this time together.
