My Mistress

Married into a wealthy family who I also worked for, at 38 my wife was less inclined to have sex due to problems with the birth of our third child (tubes tied). I was almost 40 and liked sex and get a lot less due my wife's health problem was a challenge for me to overcome. I needed a replacement for my wife for sex, I was the troubleshooter of the business and travelled regularly. But that didn't allow me to get sex, as they were short trips mostly and I was alone. But an uncle of my wife had a heart attack and was forced to cut back, and I was given his responsibility not his job. But they realized I would really need an assistant to keep abreast of everything. I was told to get an assistant and I at first thought of getting a sexy young woman, but then thought it would attract far too much attention. I love my wife and I just wanted extra sex, no extra hassles, I finally saw the solution to my problem she was 52 widowed (2 years) no children and knew her job and would be able to travel at very short notice. I'll call her Mary and she looked great, but would I be able to bed her. The answer came fairly Quickley as she was having financial problems, with health and funeral cost of her late husband. Her salary wasn't enough to get her debts paid as quickly enough to the hospital and funeral parlor satisfaction. Pay rise would help, but there wasn't much of that and getting an extra job was cut off due to her current work requirements. Being my assistant would give a pay rise which would help her and travelling would cut costs such travelling to and from work and food costs. Every little bit helps they say, she knew of the job and didn't think she had chance of getting it. But she overheard me talking to my brother-in-law, I said I wanted a capable assistant and someone who looked good to impress our customers, but nobody to start gossip about me and her. I had a mature woman would be ideal, I didn't know she was close at the time. So, she asked me if she would be able to apply for the job as my assistant. I said of course who can and added it will mean travelling on short notice and staying in some below average hotels and maybe sharing a room. Once the conditions of the work became known less people were interested. As my new responsibility meant I would be going to some nice places, my old responsibilities were still part of my job and that was the down-market part. Anyway, she got the job and had lunch with me, and my wife and she got my wife's approval. She was very eager to please as they say, and nothing was too much trouble. So, after 2 weeks working as my assistant, we had to down-market in accommodation and share a room. That was for 3 nights, but I bedded her on the first night. She was quite willing to let me fuck her and with that settled we got on very well. Finally, I made try at getting wife more sexually active, getting my wife involved a threesome with Mary and me. Which I managed to do and thus improved my sex life between my wife and me. My wife didn't see Mary as a threat, and she asked Mary to move in with us. Which help Mary by not having to rent, my wife and Mary also indulged in sexual romps without me. Mary is the perfect mistress; she lets me fuck her and also sleeps with my wife with or without me. My wife has accompanied me and Mary on several trips, leaving the children with her or my parents. The children like Mary and she is like an extra Aunt to them.
