Watched and fucked by stepbrother!!

Such a slut! My stepbrother and I were home alone and all I really wanted to do was sunbathe! As I lay almost naked in the sun, I noticed someone hiding behind the wall of the house! When I asked him about it, he totally turned me on...but did we go too far with that? I have to give him one thing, he's my stepbrother but he's good at fucking!
