I hadn't seen my half-sister since our dad died, 5 years ago. A few weeks ago I was coming out from the supermarket and going to my car, when someone called my name. When I looked back it was my sister. We went to my car to talk about what's going on with her life, and then we start to talk about our past and how we used to go to the basement during the night to fuck. She end up giving me a blowjob right there and since then we fuck once a week.
