Gabriel came back home a bit tired from his long day at work. He pick up the book he wanted. After he sat down to read it, he realized he picked up the wrong book.
"Motherfucker!" He said in anguish. Why now is it that he realized he got the wrong book. "Oh well" he thought he decided to read the book and hope it would be interesting. Of course it wasn't, the book was just about detailed information on humans, things he already learned back when he was in school.
Gabriel stopped reading and decided to find some porn to masturbate to before going to sleep. Gabriel was into Male to Female transformation porn, wanting to be turned into a woman, but scared to go through surgery. Gabriel being a bit sleep deprived decided to rewrite some of the info in the book. With a pencil in hand he began crossing out some info and replacing it with his horny ideas.
He crossed out the info regarding men having a cock and pair of balls and replaced it with men having a 2 or 4 tits, ranging from the size of their heads to slightly larger then their chests, and have a pussy.
Gabriel turned back to his computer to see what other ideas he could squeeze out of the porn he was looking through, before noticing he was farther away from his computer. He looked down to see a pair of large head sized tits on his chest blocking his view of his lower half.
He looked between his new large tits and the book, before realizing that the section he had crossed out has been completely replaced by what he wrote. He couldn't see any indication that he crossed anything out.
Still not 100% that the book caused the change and that he isn't just really sleep deprived, he decided to test it out. He crossed out the info on humans regarding the asshole just being used for pooping, replacing the word asshole with ass-pussy. He lifted his butt up and reached his hand under to feel the change. Just as he wrote, he felt the newly formed ass-pussy.
Gabriel realized he could completely rewrite humanity in the image he wanted.
