James looked up at the doctor's young assistant as she decided his fate. Denise had seemed fascinated by the whole process up to this point but now he sensed something else in her until now wholly professional demeanour - excitement. It seemed she was very clear on what she wanted to happen next.
"I think.." the attractive young woman began as she looked into James' eyes, and then back at Dr Stevens, "I think it would be simpler to have a human mind in the body of a dog than the other way round"
The doctor smiled and nodded approvingly "You've never seen a full human to animal bodily transformation have you, Denise?"
"Not first hand, Doctor!" Denise was almost struggling to contain her exhilaration as she replied.
"Set up the video equipment, we will want this one for our library"
As Denise nodded and hastily set up a camcorder and pointed it directly at James, the doctor approached him, crouched down and stared into his eyes. It was a most inappropriate time to notice just how attractive the doctor was, but he did. She looked deep into his eyes and smiled more kindly than she had seemed capable of up until now.
"What happens to you now is going to feel a little strange, possibly somewhat unsettling and you may feel some slight discomfort, but I can assure you it is a painless process. All you need to do is listen to my voice and everything that follows should come naturally"
"Ruff! Arf!" James, still naked and on all fours barked back. Even if Dr Stevens had been somehow able to force him into this humiliating position he was sure she couldn't physically change him. That was impossible.
"Good boy!" Dr Steven smiled. She ruffled James' hair and once again ran her hands delicately down his back, this time all the way to his buttocks. James tried to fight it, but despite himself felt his dick harden as she continued to caress his bum. The doctor giggled almost flirtatiously as she looked down and noted the response she had achieved "You males are all the same! Denise are we ready to start filming?"
"Yes Doctor!" Denise nodded eagerly, fixing her complete attention on James and the doctor.
"Okay James" the doctor gazed deep into James' eyes as she spoke, completely transfixing him "You are going to feel your body changing as I speak to you, but it is okay. Your transformation will be perfectly natural. You won't attempt to fight it. You will allow and embrace the changes"
James stared at the doctor in silence as Denise moved in closer, she had put her notebook down and was watching intently.
"You are going to feel a tail growing out of your body, just above your bum" the doctor informed him "a long, brown tail. You can feel it. can't you?"
To James' shock he could feel a tugging sensation just above his buttocks, he looked round and with his own eyes could see a tail emerging there. It was a part of him. He found he could manipulate it if he wished.
"Look only at me and concentrate, James" the doctor ordered as James turned his head again to face her hypnotic stare.
"Can you feel the warm, comfortable double coat of beautiful brown fur beginning to cover your body?"
To James' astonishment he could.
"Just let it happen!" the doctor encourage "Now feel your hands and feet becoming paws. Won't it be more comfortable for you to walk around on four legs than your hands and knees?"
James briefly looked down to watch his human hands morphing into neat little dog paws before looking back up to the doctor as she continued weaving her spell on him.
"Your face is changing too, you will feel it pushing out into a muzzle, your ears becoming larger, flatter and moving to the top of your head. This may feel a little odd at first, but it is all perfectly natural. You must embrace these changes. Everything about you must change to resemble a canine - your voice box, your size, even your genitalia."
James could feel more tugging and pushing sensations all over his body as the changes accelerated. He could feel himself getting physically smaller as each part of him seemed to be getting manipulated by unseen hands into a new shape and form. Eventually, these sensations stopped and the doctor rose proudly to her feet.
"That's amazing!" Denise gasped in awe as she looked down at James.
"Ruff! Arf!" James barked as, released from the doctor's control, he was able to scamper towards a mirror at the far end of her office. The image that greeted him was shocking. He was staring back at the reflection of a regular looking brown, male, Labrador. This wasn't a mind trick, he had been transformed. And there was no way anybody could tell he was a transformed human. Unless the doctor decided to release him from her spell, he could see no way out of his current predicament.
"So what now?" Denise asked the doctor in a tone that could barely disguise her excitement.
