Return of the Black Sheep

I left home (kicked out) at 16 and when travelling working here and there just to get by. Also, I woke up to my, know everything attitude and realized I really didn't know much at all. Then I met an old man 68, I was 20 at the time, he hired me as his property caretaker. Thru him I learnt respect for others and smarten up my behavior quite a bit and overtime I matured you could say. At 28 my employer suddenly died heart attack, I was shocked to find I was his heir as he had no surviving family and that he was very wealthy, he lived a simple lifestyle no obvious wealth on display. Suddenly wealthy I decided I should at least make amends with my family. Who had thought me dead as they couldn't find any trace of me like I'd dropped off the planet. Which in a way I had, working for the old man I was off the grid as they say. I was shocked to find my father had passed away two years earlier and my mother was very ill. Their lives having taken a turn for the worst. My sister then 23 tried to care for our mother and work for to support them on top of everything. The family home was being foreclosed on and their future looked bleak. On hearing of the forecloses I settled with the bank thru the lawyers of the old man used, saving their home. Then I made contact, then met them, after our first reunion meeting. I arranged for my mother to get seen by specialists, my sister lost one of her jobs because she'd taken a day to see me. I told her to quit all three remaining jobs as I would take care them from then. She did as she knew I'd money, not how much but it also gave her more time with our mother. Who started to improve slowly, with new medicines they couldn't afford before working a lot better than what she was on before. After our mother had improved, I decided we should go to my home the old farm I lived on with the old man. Selling up the family home we all headed off, I wasn't really known by the locals as I'd kept a low profile living with the old man. My return with two women and the younger having the same surname as myself, the locals assumed she was my wife and the older woman who I'd referred to as Mom to be my mother. I'm not big on socializing and stayed mostly on the old farm. My sister stayed there and didn't want to mix all that much with the locals. We got some animals, a cat for my mother and two dogs and chickens. But on a visit to a livestock auction, my sister saw 7 horses and fell in love with them mainly the smallest one. But on learning they were to be sold for slaughter asked me to at least buy the smallest one. But they were a (lot) sale to buy one you had to buy them all. Which I did, then had to fix up the barn and build a horse yard next to it. We all took riding lessons, the horses we ridable and settled in quickly. Then one afternoon me and my sister had ridden out to the pond on the farm, to have a swim. Our mother wanted to cook some cookies and a cake so stayed behind. After our swim we laid on our towels and then started to muck about. One thing led to another, and we became lovers, my sister was 24 and a virgin. I didn't have any condoms, nor did I think of using any anyway. So, my got pregnant, our mother just accepted our sexual relationship. Mainly because it was too late to say not too as my sister was already pregnant. After tests confirmed her being pregnant and no problems with baby she carried. We settled down just like a married couple. Now four years later we've a son and soon to have a daughter. As far as the locals know my sister is my wife, we do mix more with the locals those. But still keep a slight distance.
