I did because I could

In 2022 I was 28 and doing very well financially, great job and no relationship. I'd studied hard and as a result done very well and got my job as a result. First person in my family to go to university and only because I got a scholarship. So, no large debt to pay off, able to buy 2 houses (via bank Loan). One for my parents and one for me, nothing flash but suitable for our needs. My house was a little rough and needed work, parent's house was move in ready. My father helped me do up my place and it was soon ready for me to live in (October 2022). Early 2023 my uncle Mathew (56) died (heart attack) he'd always had heart trouble while I was growing up. Both his children were grown and out on their own and married with children. My aunt Katherine (52) was now alone and having a rough time. Lost her home due to Mathew's death and needed a new place to stay, my mother's younger sister had no real work skills other than a mother and carer. My parent's house was 2 bedrooms, but they had my father's widowed mother living with them. So, I took Katherine in as I'd 3 bedrooms and it suited me as I'm a lousy cook and don't like housework much. Katherine is slightly overweight and on the plain side in looks, a mostly quiet person. I gave her money for doing my cooking and housework and money to get what was needed. As I said I was in no relationship and used hookers top get me off sometimes. I'm not great looking or have a great body either, I was watching TV and saw Katherine bend over and got an instant hard-on. I was shocked at first, but soon realized I was horny, and Katherine was available you could say. But made no move on her, but the idea was there now. So, I paid more attention to Katherine in the following weeks and even cuddled her a few times, nothing too sexual. Finally on a cold and wet night I made my move. Starting with a cuddle and then feeling her up and finally asking her for sex. She was shocked at first and said we were related, and we shouldn't, but I said it will be our secret and it won't harm anyone. She finally agreed and we slept together, but once wasn't enough for me and soon she was in my bed every night. That's how it is today, and we enjoy the sex together.
