Property Dispute

I bought a house and several acres and moved in and was settling in, when a neighbor 59 I hadn't yet met came to my front and threaten me with legal action. He said I had stolen an acre of his land. I had my property refenced before moving in and I said I would check on it with the local council and do as they say. He then threatened to punch my lights out and I told him to leave. He threw a punch and as I was a martial arts trainer in the military, blocked and sat him on his ass. I then called the sheriff office and a patrol car arrived; he was told to leave my property. He then threatened to burn my house down I slept, and the deputy arrested him. It was a Sunday afternoon and the next morning I saw local council and sent a surveyor to check the boundaries of our properties. The neighbor was given a month in jail to cool down by a judge who the idiot threatened the judge as well and it to 2 months. The surveyor found the boundaries were collect and I owned what was fenced in as my property. The neighbor got released and died in a sudden explosion in his garage. The investigation found he was making a bomb and determined it was to blow up my house. But he made a mistake making the bomb and blew himself up instead. He had no family as far as the sheriff could find and his property was sold as a vacant block. The explosion had started a fire and the garage was connected to the house and with all the fuel and other such things it burnt everything very quickly. The fire brigade arrived within 5 minutes but the whole house was already well alight. I had thought of buying the block but changed my mind. Then one day the block had sold sign on it and shortly after construction started. Two sisters bought the place and were building their home on it. The sisters were unattached and 34 and 31 both were quiet as far as I could tell. Having not yet met them, they came looked at the construction and left. When the house was finished, they moved in and kept to themselves. It was a month after they had moved in, that I finally met the older one I'll call Grace. She was looking for her cat Henrietta and I was in my yard planting fruit trees. She called out me and introduced himself and asked I had seen a cat. I hadn't but then a noise attracted our attention and on investigation found Henrietta stuck between some blocks left over from building the house. I removed the blocks and Grace got Henrietta and she thanked me for my help and invited me to dinner that evening to meet her sister Kristina. I accepted as I never refuse a free meal. I'll call myself Ryan 36 and hadn't been married and was working via the internet from home. This was the first dinner invitation I gotten in the almost 2 years since moving in. The dinner was great, and we all got on very well together of course our talking got around our life histories. The sisters were like me never married and also worked via the internet. More dinners followed and then Kristina asked me did I ever want to have children, I used my standard reply Yes, but no woman has yet asked me to help her have children. I've always thought it a funny reply, Kristina then shocked me by asking me to help her have a child, adding I wouldn't have to marry her. Shocked I was, but then Grace asked would I be willing to help her as well. Not sure if they were mucking about or serious, I asked how and when. I thought if they were having me on, they would then back down. They both replied in our bed tonight, I still wasn't sure and said okay and left it to them to back down. But they were serious, and I fucked both that night a regularly ever since. I'm still single and now have 3 children 1 with Kristina and 2 with Grace (twins). We've a strange relationship, but it works for us, and we still are regular lovers and never take any precautions. Besides regular sex with the sisters I don't have to cook my own meals anymore. Threesomes are at least once a month, but usually it's one or the other.
