White Lie

My stepmother 30 is the forgetful type, married my father five years after my mother's passing. My stepmother is kind and wanted to be at friends with me. I wasn't against her marrying my father 46 and as I 21 still lived at home was in contact with my stepmother every day. Had just started trying to add to the family and then my father was sent by his employer to supervise a project aboard, normally he would take his new wife. But the assignment was in a country where women were suppressed religious grounds. So, my stepmother was staying behind, my stepmother had forgotten she had her diaphragm inside her. So, my father left thinking he had mostly likely impregnated his wife. My father expects things to go his way and if not wants to know why. Forgetfulness wasn't an excuse he would accept easily. My father has a temper, and my stepmother was nervous about telling him about her mistake. My stepmother asked me what she should do, I being a lifelong smartass. Said you have three choices; first tell you hadn't got pregnant. Second tell him about your mistake or thirdly sleep with me to get pregnant. I was seeing what her reaction would be. Not expecting her to take the third option. The first option she rejected because he would ask questions and she would surely much it up. Secondly, she rejected because she feared his temper, so she chose option three which shocked me. But also excited me greatly so we started fucking the actual night after my father has flown out of the country. I enjoyed fucking stepmother, I manage to get her pregnant and my father was very happy he was to be a father again. But fate had other ideas, my father caught up in local troubles and died as a result. Now with a pregnant stepmother and having lost my father suddenly. No thought about my stepmother carrying my child, she also was very distressed. I of course inherited everything the hadn't updated since his remarriage. But it was given I would look after my stepmother. A month after his funeral it finally hit me my stepmother was having my child. I was still attending college and living at home. I became horny thinking about my stepmother and how she had got pregnant. Decided to try my luck, straight asked to join her in her bed. She was unsure at first but decided why not. In the years since I've finished college and kept breeding my former stepmother now my wife who just had our third child. I still miss my father and mother but believe fucking my stepmother is a way of honoring him in a strange way. As he wanted a child with her and I've fulfilled his wish sort of.
