'I think I'll start with my family for small scale testing of what the book can do.' Ken thought to himself. He decided to start with his sister. He thought about what he could do to her and decided to turn her into a anthro. He thought about it and decided to make her a fox-girl anthro. He thought about her and turn the page which made two pages appeared with information about her. He tapped her race and wrote fox girl anthro in place of human. He decided to change her breasts to a d-cup size and added a few more curves to her body and three fox tails with red fur. He changed her mentality to think about her brother and wanting to be mated to him. He made it so only he and his sister would know of the changes and she looked like she was as a human.
He decided to change his age to fifteen and wrote his own memories of what happened in the added two years of his life. He also made himself slightly smarter than he was before and give himself a 8 inch long 1.5 inch thick cock. He made it so he can be the only one to use the book and if anyone sees it it would look like it was something he should be reading or a novel and forget about it. He looked at the book and thought about what to do next.
