Inheritance

I'm a late child born when my mother 39 and father 48 and an only child. I was at university (24) when my mother died in an accident. My father was worried about his legacy and told I should find a wife to continue the family name. I'm not an outgoing type of person and prefer to keep to myself. Anyway, as time passed my father decided to make it a condition of his will, I get married and have at least one child before I could inherit anything from him. That happened just after I turned 27 and my father wasn't in very good health either. My salvation came in the form of his personal assistant Rebecca 57 widow, she was main contact point with my father. I saw much more of than I saw him, anyway she came to see me and stayed the night. My father was in hospital as was usual at the time for him and Rebecca took my virginity. I was putty in her hands; she became my regular lover. As my father's condition worsened, Rebecca drained my balls. Then she said I should marry a woman and have a child and I asked who would want me. You would be a great catch, but you have to have the right wife she added. Who that do you have someone in mind I enquired yes, my daughter Pamela 25 she said. Pamela is like me quiet and reserved and so I asked would she want to marry me. I think she would I'll ask her Rebecca replied. I just nodded like I approved; the next Rebecca came again with Pamela this time and I was told Pamela was willing marry me. So, it was arranged much to the surprise of my father who was still in hospital. A few days later I married Pamela and took her virginity that night in a threesome with Rebecca. I fucked Pamela only till she got pregnant and only then Rebecca return to the bed with us. With Pamela pregnant and my father happy, I was secured in my lifestyle again. Also, Rebecca was living fulltime with me and Pamela and my father on his brief visits out of hospital. Anyway, he was overjoyed to hear Pamela was having a boy and was able to see his grandson before he passed away 6 months later. Since then, I've gotten Pamela pregnant again and it's a girl this time.
