Youngest

I'm the youngest of 3 my older brother and sister have moved out of home and started their own families. I wasn't in any hurry, why should I rush, my family is very well off and so am I (trust fund). But at home I get fed and my laundry is done by my father's household staff. Our mother passed away of cancer and 3 years later my father remarried a woman 21 years younger than himself. She wasn't married to show off, she is on the plain side in looks and doesn't dress to impress. But I've seen her naked and her body is gorgeous, big breasts and perfectly proportioned. But she doesn't wear makeup or dress up to show off. Why did my father marry her you might ask, well she is the daughter of his best client. But my father has failed somewhat and yet to get her pregnant, they do have sex. But I think my father is passed it, being a good son, I decided I should help him in some way. As my stepmother doesn't drink, getting her drunk isn't possible. But my chance came when she got sick (Flu) and was given strong tablets that made her sleep. Quite soundly also, so while she had the flu, I took my chances and fucked her several times. On her recovering my father and her had sex again and she got pregnant and would've a daughter the following June. But I still didn't know who had done the deed, me or my father getting lucky. I'd a DNA test done without anyone else knowing to find out who the father was. It was easy getting my little sister's DNA as I played with her a great deal. The results came back weeks later and I'm the father. But can never tell anyone about fathering my younger sister even now my father has passed away. I'm also married with 2 children and another coming shortly. My stepmother is very happy with being a mother and my little sister is turning into a beautiful woman. To my other family members, they believe her to be my favorite sibling. If only they new.
