The Monster Inside The Screen

There's a monster of a human being that kills people that he finds over the internet. He, however, is thrown for a loop, when his latest victim's sibling promises to make him suffer for what he did to his sister. Will he be caught by the traumatized boy that seeks revenge, or will someone partner with him to join in on the killing? Warning, there may be gxg, bxb, and gore in it. If you do not like it, I suggest you don't read it.
