Carter and the two burly attendants dragged the changing doctor deeper into the large barn. With little ceremony they shoved him inside a hay-covered stall before securely locking the heavy wooden door. However, it was soon obvious that Dr Jenkins was overwhelmed with so much pain that the notion of escaping was far from his top priority.
The doctor grimaced as his ears lengthened and his new tail started to form. The cramps in his body forced him on to his hands and knees as the transformation took root. Grey hairs had started to sprout over his body, while his hair lengthened as it followed the line of his growing neck.
“That’s it doctor,” Mr Carter teased, “the process will be less painful if you welcome the changes. Soon you’ll be just another dumb animal on my farm, doesn’t that sound wonderful!?”
However Dr Jenkins ignored the man’s advice as he continued to resist the changes. He yelled in frustration as he tried to halt the advancing changes.
Sadly, this did little to slow the process. Jenkins looked down in despair as his fingers gradually fused into solid keratin lumps. He looked beneath him to witness his feet undergoing the same changes. Soon the doctor had four new hooves as his body prepared to adopt a quadrupedal stance.
This change was quickly upon him as his legs started to lengthen. Simultaneously his belly and butt packed on more weight as they became larger and more rounded. Jenkins felt sick as his internal organs moved around inside him, while his bone and muscle structures re-orientated themselves. Then the doctor let out an agonising wail as his hips snapped forward, thus resigning him to four-legged travel.
“That’s it,” Carter continued “now you’re starting to look like a real jenny. However, there is still one major detail that’s missing.”
Jenkins struggled to hear the man’s taunts over his own screams and the sounds of his bones cracking. However, he soon sensed what the man was talking about as his still-human junk started to tingle. His eyes widened in shock as he felt his cock and balls shrink as they withdrew closer to his growing tail.
The doctor only felt more horrified when he felt a long slit open up between his legs. He moaned in despair as his testicles were pulled inside the new opening, before they quickly reconfigured themselves into a pair of ovaries. Jenkins shuddered as the last of his human semen dribbled out of his shrinking penis. Then that too withdrew, forming a new clitoris at the base of the long slit. The flesh around the opening then turned dark as it thickened. Soon a pair of pronounced lips surrounded the new orifice. It was impossible to deny now: he now sported his very own equine vagina!
Dr Jenkins was mortified by what he was becoming. He wanted to kill the bastard that had done this to him. But the pain was still too intense for him to even move. He desperately continued to resist, not wanting to end up as some stupid donkey!
However, the doctor’s new female organ had other ideas. Jenkins didn’t know it yet but his body had already started to enter estrus. Feminine hormones now surged through his warping body as his human senses were bombarded with animalistic urges. Jenkins shuddered as he felt his new vagina starting to grow wet. The lust that started to rise in his body acted like a soothing balm to the painful changes. Soon the doctor’s resistance started to crack as his new equine instincts started to take control.
As the doctor’s resistance wavered, the changes started to build up speed. By now everything below the doctor’s head was completely donkey-like. His clothes were now a pile of rags on the floor as a result of his body’s dramatic growth. His underside was now coloured white while the hairs on his back were a dull grey colour. His ropy tail was now fully-formed with a tuft of black hair at the tip. His nipples had also moved between his hind legs, now perfectly suited to nursing a young foal.
Dr Jenkins tried to plead with the farm manager as the changes started to affect his voice. “You… nngghhh… you bastard! Not a donkeee hawwww! You can’t do this to m-MEEEEEE HAWWWWW HEEEEEE HAWWWWWWW!”
Mr Carter burst out laughing as the doctor’s pleas devolved into a series of loud brays. He was aware of Dr Jenkins’ reputation as a cold merciless bastard, which made seeing him in this pathetic state absolutely hilarious.
Carter continued to chuckle as the last changes rounded off. The doctor’s face stretched out into a long equine muzzle. His ears became long and furry while his nostrils flared as they expanded. His mouth also changed as large herbivore teeth grew in, while his tongue became thicker and longer than its human equivalent. The last thing to change was the doctor’s eyes which gradually adopted a dull brown colour.
After that the changes were complete: Dr Jenkins was now a jenny in heat!
Mr Carter clapped as the process ended. “There you are, I told you to embrace the changes didn’t I? Jenkins looked around in confusion, still disorientated from the sickening transformation. “Now I think the name ‘Jenny’ would suit you well from now on. I think you’ll learn to love your new life here at the Farm Living Exhibit. Now let’s get you settled in Jenny!”
The new donkey was still too shaken to really resist as she was led away. Internally the remnants of the doctor’s personality screamed out in terror, still in denial about his fate.
