As Dr. Kennerson walked back toward the examination room his blackening nose smells Amber in heat and immediately turns back around and walks toward the receptionist, who is bent over putting a file away tail lifting her shirt and showing her wet panties. Standing behind her he moves to unzip his pants but they have become so loose they slide right off along with his underwear down to the floor.
He moves his stubby fingers toward Ambers panties and rips them downward. Dr. Kennerson sees his cock is smaller than it was before, but doesn't really care as he slides it into her pussy.
Minutes later Mark wondered where the doctor had gone and could hear moaning outside the door. Opening the door he wandered into the hallway and was shocked at what he saw behind the receptionist's desk.
Dr. Kennerson was obviously fucking the receptionist, but he had shrunk down to about the size of a 6 year old, completely covered in cream fur, a small 6 inch tail wagging furiously behind him. His ears were sticking up now while his face was pushing out into a muzzle. He was standing on the balls of his feet now, not only because of his changing legs, but he could barely keep his cock level with the bitches pussy.
The receptionist was almost a complete dog now, her clothes were stretched against her now larger frame as she was turning into a huge great dane.
Mark couldn't help but laugh at the sight as the Dr leaned forward. placing the bulk of his much smaller weight on the bitches back while his hind legs pulled off the floor as he continued to get smaller.
Mark laughed again as he went back to get Bryan and thought of what chihuahua and great dane mixed puppies would look like.
