Princess turned her head to look back at the new stallion as he moved in closer and sniffed at her vagina. She shifted uncomfortably, especially when she saw the stallion's massive shaft. The former human wanted to escape but she was cornered in the stall and her body refused to respond, instead, she felt herself get more and more aroused as her vagina winked at him.
The horse part of Princess wanted to be mated with as the heat in her loins grew. The heat was driving her crazy and she wanted nothing more than to be mounted and bred by this mighty stallion. Her eyes couldn't leave his massive shaft as she held her tail to the side, this was exactly what she wanted, what she needed. She was going to be the envy of every mare to be bred by this stallion.
Princess didn't have to wait long as Prince climbed on her back and prodded at her vagina with his massive horse member. They could feel the eyes of the mares in the Stables on them. They just got more and more aroused, wishing they were under this stud's body, but they knew they'd have their turn if not with him than with another stallion.
Princess neighed loudly as Prince thrust into her, penetrating her as she threw her head back a little. The Stallion thrust faster and deeper into her, driven by his instincts and arousal as he thrust in and out of the mare. The former female attendant had completely lost her humanity and he only cared about breeding her finally.
Princess neighed loudly as she felt him thrust in and out of her. Her still surviving human mind was having a hard time not enjoying the sensation of the massive stallion fucking her like a freight train. There was an animalistic pleasure to it as she gave in to her instincts, she no longer cared and just wanted to be taken like the animal she now was. She gasped as she felt his balls slapping against her as he thrust the full length of his cock into her.
This was all she wanted now, to be bred and used like an animal. The last of her humanity vanished from her mind with a cry as she felt him push in as deep as he could and filled her with his seed. Her vagina clamped down on his shaft and drew out all the seed it could as the horses neighed loudly.
Prince dismounted from Princess after a moment, exhausted but satisfied as he nuzzled his mare a little. She would soon bear his foals, and she would only be the first of many, he couldn't wait.
"Good boy, I believe you've fulfilled your promise," Jenkins said with a grin as he leads him out of Princess' stall as the beige mare started to eat some oats that were laid out for him.
Jenkins grinned a little when he looked over at Megan who had been watching the mating and rubbing her vagina against the wooden walls of her stall. She was just as much in heat as the others, perhaps it was time to give her relief too, he looked at Alan who's horse penis was already out of its sheath and he was watching Megan.
"Oh, do you want to breed her, hmm?" He asked as he looked at Alan, his erection was the only answer he needed as he put Prince in his new stall near Princess'. He still needed to transform the officers, but they were in good hands so he could wait a little longer "Let's see, what to do..."
