I'm convinced that there's one guy bored at home to writes all of these bullshit fantasies and incest dreams. Everywhere you look, there is a confession about f****** your brother/sister, getting with your relative, or some pedophilic confession. I hate to break it to you...but the police regularly check sites like these. So if they believed anything you say, they'll be at your doorstep quicker than you could like this post.
So f*** off, write something original, or m********* to another fantasy you sickos can come up with. At least go through the effort of making your lie realistic.
