My return home

I went overseas at 21 and working in many places I learn many skills and earnt a lot of money. Also got good advice and information that allowed me to invest my money and make lots more money. Still able to live well and with my investments doubling year by year I was raking it in. Some of my investments were a little shady, but illegal, little shady because I listened to what was said and used it to make my investments. None of the companies I worked for knew I was an investor and thought I was like most of their employees, fun seeking drunks after payday. I did enjoy a drink and have fun but didn't get drunk and always listening for any bit of information to make me richer. At 35 I decided it was time to return home, my father had passed away and my mother was very ill, and I had a younger sister 28. I returned in January 2020 and my mother never recovered and passed away in April 2020 (cancer). My sister and I was all there was as far as we knew in our family. She was quiet and not a party girl, she had spent most of her time looking after our parents first our father and then our mother was added as well. She had to cope with the death of our father and the illness of our mother till I returned January 2020 alone. At first, she was wary around me, but got closer to me overtime and we supported each other after our mother's death. No real tries to any place and living together in the lockdown 24/7. I took my sister's virginity, and she became my fulltime lover. As soon as we could I and her returned to what I knew my life overseas, 2 reasons one the healthcare was better and mostly free, and my sister could pose as my wife, and nobody would ask any questions. Same surnames in our passports, was all that was required, I quickly returned to my old habits of before my return home and only change was my sister being the fun part. I didn't need the local ladies anymore, I've my willing sister. We've 2 children now also and own our own home and are settled into our new life and my sister loves the town we made our home in. She has close friends for the first time in her life I believe, and she wants for nothing. I see to that, and she sees I get what I want also. She is again pregnant as of last week the local doctor confirmed it then. She is hoping for a girl to go with our 2 boys, I also want a girl as that will make my sister happy. Her closest friend 27 has a little girl (5 months) and was abandoned by her boyfriend on getting pregnant and her family rejected her also. My sister asked her to live with us and she is now sharing our bed. Doesn't know we're brother and sister, my sister wants her pregnant by me and so no precautions are taken by all concerned. So, we're adding a master bedroom, Ensuite and dressing room to make more room, the current master is a little small with Alaskan King bed in it. The bed the biggest we could get width and length and is 7'by 7' with a dressing room come nursery attached to the new master will service better. We're a family, not a normal family but a family regardless.
