It was almost like lightning as a bright flash covered the entire barn. Jenny dropped the gun and disoriented as she was feel into a pile of manure.
"Ewwww....this is disgusting. Stupid lightning. They should train horses to shit in toilets or something. Just shitting on the floor is just wrong." Little did she know, she would be doing just that in a matter of time.
She walked over to the changing room the family had in the barn. She started to undress down to her bra and panties. She went to grab some fresh clothes when she felt strange. Her feet seemed to be stretching her shoes. "What the...NAYYYY!" She closed her mouth wondering why she sounded like her horse. She attempted to speak again, but all that came out was horse noises.
She looked horrified as she looked back down at her feet. They had grown and ripped out of her shoes and while maintaining their shape were now huge and seem to be hardening like...hooves? Was she turning into a horse?
She noticed her hands were going through the same thing. Her thumbs disappeared and her fingers shortened matching her now hard toes of her feet. Her arms then grew out to the same length as her legs and she felt the urge to go down to all fours. Her elbows bent bankwards and become her new knees. The next thing that changed was her ass. Her ass expanded until it was the size of a horse. It looked like her normal butt, but just about three times as big. Next her vagina relocated to a more place where a stud could easily penetrate her. She cringed at that thought.
Next her beautiful breasts that she loved dearly shrunk into her chest. Her chest and belly then barreled out and she muscled up. Next, her hair became more like a mane. Her teeth also changed. And that's where the changes stopped.
She was looking at a mirror that they had in that room. She was horse in size, but it was almost like a human-horse. Besides her hair and her teeth, nothing on her face changed. She didn't have a mussel, her eyes were still as pretty as they have always been and her lips still looked nice and plump. Her lipstick was still on them in fact.
Her bra and panties had been torn turning the transformation as she looked over her naked form. Her ass was huge, she no longer had her tits, and she was walking on all fours.
Then, she felt pressure in her gut, like she had to...take a shit! Oh no, she thought. But her bowels did her in and she let a crap onto the floor like a common animal. She thought about why she deserved this when she heard Old Carly whining in the corral.
