Good Deed rewarded

I'm nothing special in looks or build and done okay relationship wise. Not in any relationship at the time this started. I was only my way home after work (2021), it was a Saturday afternoon, and it was starting to rain. I live on 7acres outside of town, I bought 5years ago as I like my space. At 29 I'd a good job and was content to go with the flow you could say. The road to my place wasn't a major road and was out of cellphone range unless you were on the high ground in the area. My home is on high ground as is all the other homes in the area, so no real incentive for expanding the cellphone reception for the phone company. I came across a car with a flat tire and 2 well dressed women, trying to use their cellphones. But they were in a hollow area and had no signal. I stopped and changed their tire for them and told them about the cellphone signals in the area. They invited me to lunch Sunday for helping them, I never refuse a free meal. Next day I headed to their address and was quite shocked on arriving at the address. It was a mansion, and I hadn't realized it before. I'd knew of it but hadn't taken any notice of it address before. The women two sisters in their fifties lived there with the daughter (25) of the eldest. Their daughter was away that day and I had lunch with the sisters, their home had no servants and was maintained by the sisters and daughter. My property actually adjoined their back boundary for a hundred yards or so. But their entrance was on another road to my entrance and their area had full coverage for cellphones. I really enjoyed the lunch, and as we talked afterwards, I got the usual questions. Relationships and my career that sort of thing, then they both enquired if I would be interested in having sex with both of them. I was quite interested and agreed and that was the start of my sexual relationship with the sisters. To save on driving miles to their place by road, I installed a gate on our adjoining boundary and drove across the fields to their home. After several weeks of lunches and sex on Sundays, I finally met the daughter. I thought no sex that day, but the daughter was going out and left after lunch. So, it was normal Sunday routine as it had become. The following Sunday, I was asked if I would be interested in marrying the daughter. I asked why me as I was somewhat shocked, they said I was a good man, and the daughter needed to marry quickly if she was to inherit her heritance. As her late grandfather had a clause that said she had to marry by 26 or the inheritance in the form of a trust fund would be given to charity. Mainly because his granddaughter wasn't into dating, and he wanted her to marry and start a family. She could probably break the condition in court, but she had left it rather late. The daughter was plain looking as she didn't dress to impress men. I didn't refuse or accept, I asked what was required of me in the marriage. No children condition was in the will, so we could marry and after a certain amount of time divorce. As the daughter was there during the conversation, I decided to agree as she seemed willing to go along with the marriage. A week later we were married, sex wasn't mentioned and so I thought wasn't on the table. My now wife thought we should at least consummate the marriage; I was okay with that, and we had sex on our wedding night then regularly since. My wife was a virgin on her wedding night and that was the main I agree to having sex with her. I've always wanted a virgin and of course there was the chance of her getting pregnant. But she didn't get pregnant until 5 months later. We get on very well and being married I really enjoy. I've a willing wife and also her mother and aunt are also still willing to sleep with me. I sold my house for removal and kept the land. Changing a tire led to sex with 3 women and my marriage and now have 2 children both boys.
