My Sister Jane update

I'm Max and I own a roadside Gas station and my sister Jane moved in with almost 2 years ago now and we started sleeping together and she got pregnant with our son David. Our mother Carol also moved in with us and also starting sleeping with us. Life has been pretty good and now Jane wants another baby and we will start trying as soon a David is 1 year old. Carol is being courted by old Fred down the road and has started to have sex with him. Old Fred is twenty years older than Carol but is pretty active for his age. Carol still sleeps with Jane and me most weeks and said enjoys the sex even with old Fred. I just brought a twenty-acre paddock behind my Gas station, Jane wants some animals besides her chickens and it joins the Gas station to old Fred's farm. Old Fred is going with Carol and Jane shortly to livestock sales to buy her animals. Old Fred will help her get the best for the money she has. I'm building a stockyard behind an old shed and we will use the shed to store feed for the animals as soon as its roof is replaced by the roofers next month.
