Playing House with my sister Susan

Growing up on a remote farm with only my Susan to play with, you couldn't fight or you were alone. So you learned to get on and as we got older we stayed close together. The farm was bought by the state and we moved closer to the city, our moth Karen wasn't very well and passed away 2 years later (cancer). Our father Robert had always been a very heavy smoker and had a very bad cough and wouldn't get check out. Then one day just fell over and passed out and was taken to hospital and it was then discovered he had lung cancer and he didn't last very long after that. He just gave up and went to join our mother is how we see it. Susan was 21 when Robert passed away in 2019 and I, David was 24 and now alone. Still living to together and very close still, both of us stayed closer after the death of Robert. We had the new home on 19 acres, Robert had bought after selling the farm. With a dog, chickens, pigs (5), cattle (9) and 3 horses to keep us busy. I also worked in the nearby town in the hardware store and Susan stayed at home. No locals knew we were brother and sister and thought as we were so close we were married. Jasper our dog doesn't like strangers and looks mean, but once he knows you, he will be your best friend. The few people who came to the house, went away thinking a very bad dog at our place. So not too many visitors come by, Susan was feeling lonely and when the lockdown started we were both home all the time and played house again. But this time I fucked my sister and it was her first time and also for myself. Of course we took precautions, nope we didn't think about them either. Before that first fuck the most we had done was a quick feel up once or twice. By the time the lockdown was over we had fucked a few times all without any precautions and after awhile and Susan missing period after period, she got tested and was confirmed as pregnant. Having every test going, the baby was healthy and nothing found wrong with him. We'll call him Robert when he is born in January. If Susan hadn't been pregnant it would've be long till she was as we had fucked the night before she got tested and didn't use protections. We're not ever going use protection according to Susan as we're quite happy the way everything is. Susan wears Karen's wedding rings.
