Fucked by her stepbrother. Is that allowed?

I was at the club the other day. Completely under-fucked and looking for a cock. When I happened to walk past the changing room, I couldn't believe my eyes. My stepbrother was actually standing there. I have to admit that I've always found him really horny. Now I finally wanted to find out... Does he really fuck as well as his girlfriends say? So I throw myself at him and a short time later I finally have his cock in my mouth. He pushes his cock into me as far as it will go. But now it finally has to go into my wet hole. After a good fucking, I finally want the taste of hot cum. I've been waiting a long time for this. But now I have a guilty conscience. Is it allowed to fuck your stepbrother? We'd better not tell our parents.
