My Sister Trisha

I'm Lucas 27 and single, I work as a mechanic and until last March I rented a place. But my older sister Trisha 31 divorced and got the 3 bedroom house in the settlement. Her husband Barry got caught fucking a male colleague and offered the house to settle their divorce quickly without too much fuss. With no children and both having good careers it suited Trisha to end it quickly as well. Trisha asked me to move in with her and I did, I usually serviced and repaired her car. So I agreed I didn't expect to see her much as Trisha was always busy. I moved a week before her birthday and we celebrated together and really drank a fair bit. I don't remember much, but I awoke in her bed naked with her also naked and cum leaking from her pussy. I did remember fucking someone and than I remembered it was Trisha. At first I was a little shocked, but it soon passed, Trisha awoke and she thanked for fucking her as she said she really needed a fuck. Feeling horny I asked was she willing to fuck again and she said okay and we fuck several more times that day. That evening (Sunday) I was thinking of asking her to let me sleep with her that night, but she asked me too first. I've been sleeping with her ever since, my birthday last month she asked me would I get her pregnant. I was already fucking her regularly and said okay. She said she would get tested when she got pregnant and only have the baby if everything was okay. I'm really enjoying fucking Trisha and I don't date anymore myself. I wasn't a great ladies man, but done fairly well with the girls I dated. But Trisha is the best lover I've ever had.
