"Such a shame to lose you two, but the African exhibit is in need of a Zebra stud and another mare," Jenkins said as he put the syringes away. "I'm sure they'll be more than happy to put the both of you to good use."
"You can't do this, we're human beings..." Mark said as they tried to struggle, he could already feel fur growing along his legs and his crotch. "You can't do this to us, it's a violation..."
"The moment you came in here you gave that up," Jenkins said with a grin. "It's a little legal loophole, anyone who enters here is exposed to a virus that changes their DNA with our patented genes. When you are exposed to the right stimulation it triggers the transformation, you are for all intents and purposes already an animal, it's just a matter of finishing the job."
Mark looked over at Georgina who was trying to struggle just as much as he was. He blinked in surprise when he heard her let out a moan, she wasn't trying to escape she was getting aroused already, he could smell her arousal and, something more which made his cock suddenly stand at attention.
His thoughts of escape were starting to slip from his mind, instead, he watched as white fur with black stripes started to cover his partner's body. She moaned loudly as she tried to rub herself against the chair which only made him hornier as he stared at her as a tail started to form out of her butt.
"Well, it looks like you two are already getting into it," Jenkins said with a grin as he nodded to the guards. "Keep an eye on them, let's let our new Zebras finish each other's transformations."
He got up and undid the bindings on the two transforming humans. Georgina turned and fell onto all fours as her bones shifted, keeping her on all fours as she adjusted her growing tail to reveal her now equine vagina as it winked at him. "Ohhh... take me you stud, breed me, I want to carry your foals!"
Mark didn't even hesitate as his new animal instincts overrode his human inhibitions. He looked down at his cock which already looked equine with it's flared tip and was growing larger. His new instincts demanded that he take and breed this mare, and he was not going to ignore it as he moved up behind Georgina and pressed the tip of his cock against her vagina before he finally thrust in and she moaned loudly.
Jenkins grinned as he watched the transformations start to speed up. Georgina's breasts retreated into her body as her new teats formed between her legs and her chest barreled out. Their hair turned into manes as Mark's tail formed, their bodies being covered with white fur with black stripes as they turned into Zebras.
Mark's body changed as he no longer could stay on his hind legs without leaning on the mare. He didn't care anymore as he thrust faster and deeper into her, her human moans becoming inhuman brays as her neck stretched out and her face started to push out into a Zebra muzzle. Mark joined her in braying as he thrust faster, his now full-sized Zebra cock slamming into her as his balls pendulumed, slapping against her backside.
The two former officers no longer cared as they mated, their new animal instincts had completely overwhelmed them as their human minds were letting out pathetic whimpers. It finally came to an end as Mark shoved his entire shaft into her one last time as his balls churned and massive amounts of his seed poured out into the mare, filling her womb as she clamped down on his cock and drew out as much of it as she could.
With that, the former police officers were completely gone, leaving simply a Zebra mare and stallion in their place as Mark calmed down and pulled out of her, their mixed juices dripping out of her vagina. They were full Zebras as Mark nuzzled her gently.
"There we go, that wasn't so bad was it?" Jenkins asked with a grin as he patted their necks. "You'll both be welcomed into the African savannah I'm sure."
He walked off as men came to take the two Zebras away. Now he just had to figure out what to do with his former boss, perhaps he could finally make good on "her" promise to alleviate Princess' heat. Then again there were other mares who needed attention too, and Alan and Megan had been causing problems.
He had a lot to do, and knew that he now had to get this placed filled up. It was just a matter of figuring out how.
