There’s nothing like family, they are always there for us when we need. So, when I was really horny at my step brother’s house, and his girlfriend were there, only both of us, I thought that the best way to deal with this sensation was ask her for help. She refused it at the beginning, but five minutes later was licking my cock as a kitty with milk on a plate. She even change her clothes to something more… how to say it, slutty. She sucks cock like no one else. My step brother is a lucky man for have her, but I am more lucky to have him, because without him, I never could have that ass over me, riding my cock. I hope he never finds out, but that’s complicated, because I left her holes a little more wide.
