Stepsister

My father then 59 married again and his wife was 38 and already had a daughter then aged 17. I was then 28 was away overseas working and was unable to get back for the 2020 wedding due the pandemic. My own mother had died in an accident when I was 17 and I don't have siblings. My father is a heavy drinker and smoker, and his health isn't that good anymore. But he won't stop smoking or drinking, he's the reason I don't smoke and rarely drink myself. I returned home in 2021 and at first had to work on the other coast and rarely saw my father and his new family. In early 2022 I returned to live with my father and his new family. I like my stepmother she not a wicked stepmother like you read about in stories. Her daughter is very quiet and at first, I thought she was scared of me. I'm not what you could call handsome, but I'm not scary looking. My stepmother told she was a slow at making connections with other people and once she gets to know you, she'll loosen up towards me. So' I was always very controlled around her so not to scare her. She became more open to me and by July she had mostly relaxed around me. I went out of town for work and wasn't going to be home my father's club honoring him. But due to a sudden change in my work schedule I was able to return early. So, I could attend but had no date to take with due to the lateness of my return. My stepsister wasn't going as she didn't date and would've been too nervous to go on her own. With me being back I asked her to go with me and she agreed. We had a great time together and bonded closely. I started dating her as I liked being with her and she was always available. We hadn't started any type of sexual relationship and the most we done was a peck on the cheek. My father went away with my stepmother, and I was home with my stepsister. Then there was a wild storm strong wind, driving rain and very loud thunder, plus a great amount of flashing lightning across the sky. I was watching the light show across the sky and my stepsister screamed and came running and sat almost on my lap she was so close to me. I was happy to give her a cuddle of reassurance and quickly noticed how sex she looked in her babydoll PJ's. As the storm continued, I got more and more aroused by her being so close to me. Finally, I kissed her on her lips, and she kissed me back. Well, the short version is she joined me in my bed, and I took her virginity. Once I had fucked her, we became lovers fulltime as it were. By the time our parents had returned she was sleeping with me in my room every night and had moved in her things. She might be quiet and a bit timid, but once she accepts you, she isn't backward towards you anymore. The only thing was she had been a virgin and wasn't on any precautions whatsoever. I hadn't taken any myself either and once I realized my mistake next morning had decided to marry her and had already asked her before our parents return. She had accepted my proposal and that was the reason she moved into my room straight away. Her mother accepted the situation, my did also after getting over the shock. He hadn't seen it coming unlike his wife, who thought it was high possibility we would marry. That was September and a quiet private wedding in October. Last month my wife tested positive to being pregnant. I could've waited and seen what happened, but really think I made the right decision still. My wife is frilled to be pregnant and so are our parents. I'm ecstatic and as my wife wants to stay close to her mother, we aren't getting our own place.
