After the Divorce.

I'm David 50 widower 3 grown children who have all left home. I sold the family home after my late wife passed away 2 years ago and downsized to a 2 brm cottage. My sister Jane 41 got a divorce from her husband Luke, she found him in bed with his business partner's wife. They have 2 children both a university, so after the divorce Jane came to stay with me till she could get back on her feet so to speak. Jane had married young and didn't have much work experience. So at first she kept my cottage and cooked for me, severval months ago I took some holidays and Jane and I when on a road trip together. We had a caravan and went to a couple of places sight seeing. On one of our stops, there was a violent thunder storm that caused the caravan to rock and Jane had never liked storms as a child. She came and got into my bed and hid under the covers, I told her not to worry. But as the storm got worst the more afraid she got, soon we were cuddling and then I just kissed her and she kissed me back. I started to feel her up and went down on her and then we had sex. It was great and it took her mind off the storm and when the storm had gone we were still in bed together and stayed together for the rest of night. Next morning I fucked again and we continued to fuck even after we returned home. Last week Jane told she me she was pregnant. I was a shocked at this, but was also elated as well. We have decided to keep the baby and have told the families that she had casual sex on our trip and she dosen't know where to find the father. I told my family that I will help Jane with raising the child and he/she will have the family name. They all seem quite okay with it, I'm adding room to the cottage and sleeping with Jane everynight.
