As Jeff went back to his room he thought that he really didn't like his Dad being so domineering. He wanted to be the one in charger but he wanted his Dad to still be his Dad.
He sat down and made some changes to his dad.
First he changed him from being the big bruiser that he was and made him into a rotund almost sissy little bitch. He widened his hips and took all the fur from his body. He was his pig.
As he made these changes he also made some changes to his endowment. That log that he had was now so short that even hard it couldn't show from his belly apron. He gave him big balls though. They were like cantaloupes swinging between his legs causing him to have to walk bow legged.
But the big sexual change that Jeff gave his father was that he made him subservient to him in every way possible.
And one of the thing that Jeff loved most to do to his father was bestiality. That was why he gave him the wide hips so that he could take any cock imaginable.
They had several great danes and they used his father often. The neighbors would bring their pets to fuck him.
And when Jeff felt particularly randy he would bring his dad out to be fucked by all sorts of farm animals.
His dad loved it and so did Jeff.
