Perfect Isolation spot

Last year with the arrival of the coronavirus and the threat of a lockdown coming into force. I headed for the hills literally, I own a house in the mountains. My grandfather build it back in 1948 after returning from ww2. He called it his Cabin of Peace, but with 4 bedrooms and 2 bathrooms and being on 200+ acres. It's too big to be a cabin and over years since it has been modernized and had solar panels and a wind turbine installed. With the passing of the years and the family improving our financial situation greatly. I didn't need to find work on finishing university, I could have just lived off my trust fund. But I went into the family business, with the passing of my grandfather in 1990's and my father taking over the business and then his sudden passing in 2006 at the age of 61. It all came to me and my 2 cousins, I lost mother in the early 90's to cancer and didn't have any siblings. My father never remarried and with only a sister who also passed away in 2003. I and my 2 cousins started to sell off sections of the family business. As neither of us were all that interested in running it, I wasn't going to put 60+ hours each week into the business and moved to investing in the stock market and government bonds. Easier to handle and let me travel and enjoy life. So at 42 in 2020 single and no family except my 2 cousins Samantha 45 divorced and Emma 37 single, I headed off to the cabin to get away from the virus, I took everything I would need and along with my 5 horses from regular home just outside the city. I had them and feed for them delivered to the Cabin of Peace. A week after I had arrived, lockdown was to come into force and I made a quick trip to the nearest town and got extra food and drink. While I was in the town I got a call from Samantha telling me she and Emma were heading to the cabin also. I asked did they have everything they would need and she said yes. I got back to the cabin and the following morning they both arrived, along with their old dog Rex (12+ years old). So now all together , we started to settle into a routine, Rex chose to lay need the fireplace most of the time and Samantha laid on the couch opposite him. Emma likes cooking and would be in the kitchen most of the time and me. I went horse riding or getting more firewood stacked up. On a rainy day I got bored and was in my room watching porn on laptop and Emma came in to tell me lunch was ready catching me watching porn. She didn't say anything except that lunch was ready and left. After lunch Samantha went back to her reading and I help Emma clean up the dishes. Emma has always been really quiet and I hadn't heard of her ever dating. But before the virus, I hadn't really thought about love life or Samantha's love life for that matter. Emma has a nice body and doesn't dress to impress I think is the right way to describe her. Always well in 1960's housewife style as you seen in TV show, wears glasses and doesn't wear contacts ever. Samantha is the polar opposite to Emma and dresses to impress in the modern style. With no children, neither of them had anyone else to look after. So while I was assisting Emma, I started checking her out and started to become attracted to her sexually. The rest of the afternoon I watched porn and thought of Emma, the next morning it was fine and I was going riding and asked Emma to join me. She likes riding and accepted and we headed off towards the forest trail. After riding for awhile we stopped and I made a pass at her. She backed away at first, but I was able to kiss her and we started cuddling and I almost got my hand into her panties. But she said it was time to head back, not wanting to upset her we headed back. Sandwiches for lunch and after I went to my room for a laydown. I was going riding again after and was wondering should I invite Emma again. Shortly after Emma came into my room and joined me on my bed and she kissed me and we were soon cuddling and kissing. I decide to push my luck as it were and started to feel her breasts, then her grain area and got my hand into her panties. With her allowing me to do anything I wanted I decide to go for broke and straight asked her sex. She hesitated at first, but then agreed and telling she was still a virgin. So I took it slower than I would have before she told me she was a virgin. But I fucked her and we laid together after and then I decided to go for it again and she let me fuck her again. That night after dinner and everything was done, I decide to go to bed. Telling both them I was going to bed, Samantha decided it was time for her also and Emma just gave me a smile. I had the master with its own bathroom and I went to it. Shortly after Emma came into my bedroom again and asked me would I like company for the night. I just nodded and we went into bathroom and had a bath together and then to bed together. We had sex again and then again in the morning, we finally left the bedroom to get breakfast and Samantha wasn't up yet. Emma made breakfast and just as it was ready, Samantha came into the kitchen. I was sitting at the table, Rex was eating his food and Samantha asked what's for breakfast. Samantha still didn't know anything was going on between Emma and me. After breakfast was finished me and Emma went riding again and we soon made it our normal routine. It was about a week or so later that it dawned on us that we hadn't been taking any precautions at all. Emma was a little worried at first, but relaxed when I said I hope she does get pregnant to me as I would her to be the mother of my children. So nothing changed and several days later it rained again and Emma and I were fucking in my bed and Samantha came in to ask me where was Emma. Catching us fucking shocked at first and a stunned I think, but as she recovered from the shock said good to see someone some fucking. She turned to leave and Emma asked her to join us this was a shock to me at the time and Samantha at first also. But she shook her head and left. After our fuck we showered and went to see how Samantha was getting on. She sitting patting Rex and Emma sat down beside her and they started talking, I left to talk and went got firewood from the stack. After I had finished Emma asked me would I like a threesome that night. I was a little surprised, but said okay. So from then till the lockdown finished, I was fucking both Emma and Samantha. Emma got pregnant we went interstate and got married and Samantha still joins us for threesomes regularly. With the birth of our son Nathan. Both Emma and me couldn't be happier, Samantha is living full time with Emma and me at my place. Old Rex is still going but and we got him mated with a bitch to continue his line.
