Isolation

I'm Keith 30 single and work from home, when the coronavirus started I packed up and moved to my holiday cabin in the mountains. It had everything I would need to isolate, solar power, good water supply and internet connection via satellite. I took along as much food and supplies as I could carry in my vehicle. I could also fish and add other items in the local area to my food supply. I also got a supply of over the counter flu medicines and alcohol. I thought I would be okay away from the city and I've missed the coronavirus so far. I've no siblings and both my parents have passed away, with only a aunt and cousin that I know of. Aunt Amanda 43 my mother only sibling and the younger of them and her daughter Caren 24. They lived in the next state to me, they knew of my mountain cabin and called me about joining me there. I agreed and told to get anything they might need in isolating, as we would be unable to much stuff for a while. They turn up 3 days later and also had food and flu medicines and feminine products and face masks and latex gloves. I could say they are the most gorgeous women in the world, but they aren't. Like me they are short and a little overweight, the cabin only had 2 bedrooms and I let them have the larger one. They also had their cat Tiger, an overweight tabby, so the bird life would safe as he was too lazy to chase them. Over the next week or 2 nothing really happened. But after a period of rain, had stopped our washing drying. We started swimming in the nearby lake naked alone at first and then together as a group. I found myself getting horny looking at them naked. But not brave enough to ask them for sex. I would walk away into the trees and masturbate myself, I did this for a few days. Then Amanda asked me straight out for sex as she too was horny and me being the male around. At first I was unsure, but finally accepted and we fucked. I was to pull out before I came as we didn't have condoms or anything else. Caren knew we were fucking and wanted to join in with us and we let her. We started sleeping altogether at night and we would fuck most nights. During a bad thunderstorm, Caren and me were fucking with her on top and I felt I was about to cum told her to get off. But a loud thunder clap made cuddle to me and I came before she got off my cock. Leaving my sperm inside her, Amanda said not to worry it would be okay. Amanda then wanted fucking and to show Caren it wasn't anything to worry about stayed on top of me until I came inside her. Now several months later both have missed their periods twice. We got test kits as restriction were eased and both showed positive results. I'd only came inside them the once before and now when we fuck and I cum inside them all the time. But we only just found out that the test kits we used have a high rate of false results. But as we had already accepted the fact that they were both pregnant, we don't care if the test result were wrong.
