Sister

I'm John now 29 and living my sister Emma 25 and our first child Jane. Our Parents died 15 years ago in car accident and we went to live with aunt Samantha 56 at the time the only relative we had. Our parents were in their late thirties when they had Emma and our mother as far as we know had no other relatives except her parents and they had both passed away by the time I was 7. My fathers parents passed away in the same accident as our parents. So Samantha was our only relative, she had no children and took good care of us, she had a series of strokes 5 years ago the last was fatal. Emma was always very close to me as a child. I was her carer from a young age and was told by my parents it was my job to look after Emma. It was me she came to on stormy nights and would snuggle up to me in my bed. It was common for us to sleep together and even shower together, even when we matured. I even got hard on in in the shower with her some times. Nothing sexual happen then, but when Samantha passed away. We stayed closer than ever and on Emma's twenty first birthday, we had sex for the first time. After that we would sleep together every night and we sold up everything and moved away to town and told everyone we met we were married. I work as a mechanic and Emma keeps house and looks after Jane and she wants more children and we're working on it.
