Stepmother

Short Version, my father divorced my mother married again and then divorced again. Never happy he kept looking for the perfect woman. Just by chance I was his only child and my mother passed away when I was 15 and I came to live with my father. Who was on his third or fourth wife at the time, anyway it didn't last and then another wife. My mother was his longest marriage at 7 years and the other lasted about 5 at best. I was 24 and going to university when he married his current wife, she looks to be his last as he is ill (cancer) and it's not looking great at this time. My father is very well off and always has prenups when he gets married. Tried and tested he uses the same style prenup each time he gets married. His latest is dumb like all the others and looks great in a bikini, I'm the only other person living with them. The staff come at 7 and are gone by 7pm. A nurse comes every day and checks my father and goes about an hour later or till he is taken away by ambulance if required. The hired help don't work Sundays and when my father was taken to the Hospital last June. It was just me and my stepmother on the Sunday, I do date and have gotten lucky a couple of times. I was going thru his papers and found his will and I would get everything as the only child. His wife would only get what was in the prenup unless she had a child for him, which was highly unlikely. Anyway, I really liked my current stepmother and not as a stepmother. But as a friend she isn't self-centered like my previous stepmothers, I would like to bed her a great deal. With my father's condition getting worse and now knowing the conditions of his will. My devious side came to the fore, I get it from my father. So, when I got her alone after the staff had finished for the day. I offered her a deal she sleeps with me,
I get her pregnant and she is better off if my father dies. At first, she was shocked and refused, but later she changed her mind. Helped along by a health report of my father, which wasn't very good. She agreed and just took my word I would keep my promise. I started fucking her regularly and succeeded in getting her pregnant in July and in early August my father died. I had no intention of saying the baby was my father's child. But nor did I intend to leave worse off, as I had fallen for her myself. So, I told her I had heard the lawyers would want a DNA test because of my father's health and suggested she marry me instead and we did last month. Only the 2 of us knows yet and I'm very happy with my actions.
