Description
We always had a very open relationship. My sister always liked to talk with me about her boyfriends and specially about her sexual life and that turned us on. At first we tried to hide it and change the subject but we both wanted more, and one day it happen. While she was telling me about her last boyfriend and how she sucked his cock for the first time, she actually tried to show me and that made me getting hard under my boxers, so she took it out and suck it. That's how all started between my sister and I. We now do it all the time.
