As the two continued to walk down the trail, Jennifer noticed that her body was continuing to change. She could feel the transformation speeding up as her body shifted. She finally had to stop Steve as her clothes broke into pieces as they weren't going to fit anymore and she moved off of the stallion that used to be her boyfriend.
She fell forward onto all fours as her vagina moved into place and her breasts formed into her new teats that filled with milk. She let out a light whinny as she nuzzled Steve a little, even if she was a horse now she still felt something for him. But now she needed to get back to her foals.
As the two new horses walked into the stables they were greeted by the Stable attendant who stroked their manes lightly. "Excellent, excellent," she said with a smile. "We have a handsome new stud and broodmare for the Stables, and I'm a woman of my word Jessica."
She lead the two into their adjoining stalls. Jessica saw the two foals from before who moved back into position and started to nurse from her teats as she began to eat from the food trough. She was content in her new life, even if she remembered her old life, she was happy to just be a horse with her two foals.
As the foals nursed, her mind slowly slipped away and her memories were re-written. They weren't some foals she had found in the Stables, they were her's by birth, she was a horse, she had always been a horse.
The attendant smiled and looked at them again. Now that they had two new horses, what were they going to do with them?
