My widowed neighbor

I'm divorced 44 and live alone my closest neighbor is across the street, I'm a mechanic and bought my house because it has a large double garage. I'm able to work on cars in my spare time to make extra cash, without having to alimony out of it. Mostly on weekends, never when I've my children (both teenagers) who I get once a month. My neighbor across the street is 48 works several jobs and needs her car, never dated as far as I knew, but she of course could see me fixing cars. So, when her car started playing up and short of money as usual, she came and asked me to get it started so she could get to her job. I got it started but it really needed a good servicing and some worn parts replaced. I told her that and she said it would have to wait until she had spare cash. Of course, once things started failing more followed, an unreliable car was something she couldn't afford. She had also noticed I never dated either, she got the idea of a type of mutual satisfaction deal. She would satisfy me sexually and I would service her car and change any parts that needed it. I was shocked at first but decided why not, so she stayed the night, and I lend her my pickup to get to her jobs while I fixed her car. She stayed the night again. The next weekend my children were visiting, but I worked her car again to finish it off. I'd to get a part ordered in, my neighbor again used my car again. My children just sat watching tv or playing on their phones as usual. Only after they had returned to their mother did my neighbor stay the night again. We now have an arrangement I maintain her car she drains my cock perfect arrangement.
