My ex-wife's mother

Four years after my divorce was final and my ex having remarried two years after the divorce. Free and clear as the saying goes, no alimony or child support left to pay. My two children were supporting themselves both had join the military. At 45 I live in a two-bed apartment mainly working from home via the internet. A cleaner twice a week and dined out mostly instead of cooking my own meals. On one of my visits to the company offices, I met my ex-mother-in-law 62 (MIL). She was looking for work and missed out of the job mainly because she was seen as too old, I believe. We'd always got on fairly well and since her own divorced nine years earlier, her daughter 43 ignored her preferring her father to her mother. My wife was always a daddy's girl, anyway my ex-MIL had lost (company closer) her job and was struggling to find another. They had a 50/50 split no alimony divorce, so she needed to find a fairly good job to get by. Anyway, I asked her to wait for me, and we would catch up and have a coffee. She told me her troubles, I also had trouble, my cleaner had had a stroke and had to stop her cleaning job. Finding a replacement wasn't easy as there's shortage of cleaners. My ex-MIL also needed to find a cheaper rental. I decided to offer her my spare room in return for keeping my apartment clean. I'm a fairly tidy person and she could still look for work without worrying about her rent. A win/win I thought she of course accepted that was early November last year. No problems with her living with me I rarely dated, mostly couldn't be bothered with all the hassles of dating. If I wanted a fuck, I could hire a hooker have sex and no hassle as far as I was concerned. If not interested in hiring a hooker I would masturbate myself. So, it wasn't too long before getting caught cock in hand as they say, she had left I thought to look for a job. I hadn't seen her leave just heard the door closing; she'd just went to put washing thru the machines in the basement. Her return was quieter than her leaving as she had her hands full with the laundry. On her return she entered making no noise at all and came to see me if I wanted a coffee catching me mid-stroke you could say. After an awkward silence, she offered to get me off and I accepted. Her hands were quite soft, and I really enjoyed her masturbating me. That was on a Wednesday and no more was said after that. But on the Saturday afternoon she was cleaning, I was watching her and got horny. Never one to stay quiet about anything I asked her would she get me off again. She thought about it and agreed, this time she had me lay on my bed and started to stroke my cock and I started to feel her up. She stopped stood up and completely undressed telling me to do the same. Once we were both naked, she started masturbating me again. She also started sucking my cock, I came in her mouth and she swallowed it. We laid together for a while and I got aroused again, but instead of asking her to masturbate me again. I got on top of her and fucked her. She didn't try and stop and ever since then she shares my bed. Last week I got promoted and was entitled to an assistant and so hired my ex-MIL as my assistant. I've to be at the office mostly now, but I've very willing assistant who lives with me.
