One day led to the next and it all sucked! As the second day of sucking continued Scott noticed the girl need not bend over to mouth his shaft. Also the girls stood closer to his chest and seemed to be working the erect shaft about in her mouth.
As Scott could only watch and enjoy the wild feelings the friendly doctor showed his face. "I see she has excited the sensation process to it's new and refined style. Please note that she stands closer to your fce as the penis of a man has changed to one on a bovine animal. A sturdy sheath has grown to hold your monster cock when not in use. The penis has become what must be considered a bovine bull's cock as the circumcision of your youth has spread and you are very much of bovine form in your shape. The length of the cock has increased to aid your mounting of tall cows. It is narrow at the tip but quickly enlargens toward the base. It's still pretty and very pink as most bulls have and in time enjoy. The beginning of hair growth has sprouted on thighs, arms, and face. I expect that over the next week much of your bison form will begin the takeover. Rest later if you can!" the doctor said as he patted Scott's hairy forehead.
At last the girl did not come back and his two day orgy was finished. Thinking to lay quiet and relax a little the calm was broken by the doctor and a tray filled the syringes.
"It's time to begin the mircle to come! I have here serum for skin color, hair growth, muscle builders, bone interaction, and last but not least a small needle to insert the horn buds into the sides of your skull." said the doctor with a smile.
As on injection stung and made Scott wonder how soon it would show the changes he whinced and screamed aloud. The needle pierced his flesh and pressed into the bone of the skull. A quick press jab and one horn bud was planted. As the doctor stood to Scott's right side the next needle burried itself into the skull.
"As you felt pains before the horn buds will root themselves in the skull. The roots will wiggle their way into the brain gray matter, I told by some it's like having ants crawling inside your head. If your hands were not strapped down one might rip off your face to get at the itch, so let the changes begin!" said the doc.
Now Scott's muscles rippled of change. As pain and pleasures mixed in odd way his bison cock became erect and waved about in the air. As the day became night the screams of Scott's agony rang down the hallway outside his room.
Pain, like nothing he'd ever felt arched his back and strained muscles in arms, legs, and back. Rolling his head from side to side the internal itching began. Pleading now to die he screamed for the doctor to come and kill him. Yet as he screamed and wiggled in the straps the lights in the hallway went dark. "Nobodies listening, nobody gives a care, Oh, oh, oh..........!" As Scott had a thought to exclaim his pain the words began to lose meaning and expression now was by moaning and grunting sounds.
Time seemed without end as the itching increased till he thought he was going mad. The doctor came in but without a word looked him over and left the room. Toilet needs were out of the question as Scott sprayed the air with one yellow stream after another. The sheets became discolored and a smell which touched his mind as one of comfort and friendly.
At last the pain and itching slowed and soon enough was gone. The doc came in one night since no sound of yelling, moaning, or bellowing was heard for over and hour.
Looking down close into Scott's changing line of sight the doctor spoke, "Can you hear me Scott? If you can hear me shake your head! Fine, I have news that you will be moved to a box stall coverd in sweet smelling straw. You will be cleaned of stool and placed where your body can build mass. Do you understand me Scott?" asked the doctor seeing the wild eyed look in the face of the volunteer.
In fact Scott could not make out what the man was saying since the itching had destroyed part of the human brain. As some words stuck and floated about in his mind the meanings were dim at best. Straining to understand where and what he was Scott just laid there listening.
The move to get a bath and at last to step into the 20 x 20 box stall offered Scott some comforts. Walking in circles the bison looked about for a way of escape. Sniffing the air Scott was now more bison bull than human in mind and soon in body.
Set up high for safety a large mirror reflected the changes in Scott. As he caught sight of his reflection the facts of the change were quite apparent. Now tears welled up and ran down a curly hairy face.
Dark eyes peered back at the face which sported bare black skinned nostrils and lips. A muzzel made to graze the pasture now was part of what used to be a middle aged human male.
Groaning a little Scott turned his hips to see a side angle look at thighs which had broadened to look like those of the bison animal. A switch at the end of a short tail swished over his base asshole. It tickled as the coarse hair stroked the smooth skin. A twist back offered the sight of a huge sheath attached bull style to Scott's belly.
Prancing in a cirdle the perky feeling of cloven hooves, long feet, hocks in place of heels and the spry intense feeling of agile strength. A sudden enjoyment brushed Scott's thoughts a the bison bellow of bullish approval shouted into the air.
"Soon very soon my good fellow you shall be the property of a great Zoo!" said the doctor as he closed and locked the stall door.
