Car accident

I (41) lived alone and had only one nearby house, I've a classic car 1963 Corvette Stingray. It's my pride and joy and I left it in my driveway after returning from a drive as I needed to use the toilet urgently. It was well off the road and as I was returning to park it in my garage, I heard a crashing noise. Getting outside I saw my neighbor 20 had hit my car, she had pressed the gas instead of the brake. Mostly likely due to the high heel shoes she was wearing, luckily for me it was glancing strike. Not a real had hit either and had mainly scratched the paint and left a small dent. Her car came off worst headlight and indicators broken, but her car wasn't a classic like mine. Her mother 38 was away, and she had no job. My car was being renovated by me and a repaint was the next and last to be done. The dent popped mostly out and a little panel beating it would okay again. But it would delay it finishing. She was very worried and not having much money herself and fearing to tell her mother as well, she offered me sex was compensation for her damaging my car. She isn't centerfold model, but she is pretty, and I got aroused by her offer. We came to a deal, and I also fixed her car problems as well. Sex started that day and was to be 12 times, I let her offer first and she suggested a dozen and I was thinking of 3 or 4. As I said my car was to get a repaint and the dent was easily fix. She stayed the entire night with me, and I liked her company. Anyway, she was true to her word and we'd 12 sexual meetings, which was actually 15 fucks. But it took over a month to complete, I thought we were careful and not seen by her mother after her return. Well, we weren't seen, but the daughter talks in her sleep and her mother found out that way according to her. Her mother wasn't concerned I was fucking her daughter or about the reason why, she just wanted to join in the fun as she called it. Her mother slightly overweight for her height approached me for sex. She had heard her daughter mention I was very good; I thought why not and thus I started fucking the mother also. Shortly after I had my last agreed fuck with the daughter. Her mother came and joined us as well, I expected the daughter to move on with her life. But she really did enjoy our sex and still came for sex as it had become regular during our agreement. Then the pandemic started and as we were isolated away from most of the people living nearby by a hundred or so yards from the next closest neighbor. We continued our sexual relationships, of course you get lazy or careless and we did as most people do. We made at least 2 mistakes, and I got both pregnant. Which would make me the father of 4 children, counting the 2 I had with my ex-wife. After lockdown and births of our children I married the daughter, and they sold their house and moved in with me. Now years later and 3 more children 2 from my wife and 1 from her mother. We are quite happy with our lives and continue to live peacefully as we always had.
