Marie, Josh and the other donkeys were sold to a donkey breeder farm. It wasn't really a bad place, it had big open spaces, they gave plenty food and cared for donkeys. But Marie was still sad about losing her humanity.
At their first day, Marie and Josh were in a wide field, enclosed by a padlock. They were around by dozens of donkeys that ate, brayed and a few were mating with each other. The smell and sound of the braying was overwhelming, her senses enhanced by her new form. But Marie was still embarrassed to be naked and on all four, her tail was between the legs and her ears were down.
"So you see, being. A donkeys not so bad. At least you can still move. The last teacher got turned into chocolate"
The donkey that used to be Marie snapped. Her terror was quickly replaced by anger. Rage unlike anything Marie had ever known flowed through her.
"Hee Haw! Hee Haw! Hee Haw! Hee Haw! Hee Haw! Hee Haw!" she brayed with a rasp. Suddenly, She heard her stomach growl, she was hungry. She had not eaten anything since she was transformed. Unfortunately, the only thing in sight was grass. "A real donkey should eat grass, but I'm not a real donkey", Marie thought. Marie looked down, and noticed the lush grass around her. The hunger increased so, after a while, she decided to take a bite. After the first bite, Marie literally threw her whole muzzle into the dirt and grass and began taking off large bites off it, not even giving the bunch on her mouth a couple of bites before she was already taking another bite at it. The grass tasted good, really good.
It felt natural, almost comforting. Marie just wanted to keep eating and... "Wait? What am I doing? I am a girl, not a donkey!", thought Marie but she couldn't stop eating because the amazing taste.
Taking each bite was becoming easier and easier, and even with the feeling of shame overwhelming her mind, it was soon also coming to her paired with a feeling of joy, maybe even pleasure. She was right there, on four legs, looking and braying like a beast of burden. Her embarrassment could be no higher, but not because of what she was acting as a real ass but because little by little she was growing to enjoy it and that was scaring her.
Then, Josh was approaching her, clearly very interested in Marie new donkey body. For him she was beautiful as a girl and as a jennet. She brayed to him to stop his intentions. She was in love with him, but she didn't want to mate as a pair of common asses. Sudenly, Marie saw what was between his donkey's legs, she was surprised. She felt a little bit... turned on. His legs were stronger than his human form, and the thing between them was even more...
"N-no! I didn't want this" Marie thought shaking her head. She told herself to run, but for some reason she didn't move, a growing part of her not wanting to stop it from happening.
Her donkey instincts were taking over. Marie was in heat, and needed that.
"No! This wasn't right!", Marie her back legs, trying to keep the advancing Josh. But it was not enough to stop him. Then, she deceived herself "Well, there are no problem, Josh is a human like me and we love each other". Without thinking about it anymore, Marie lifted up her brown tail , allowing Josh to hit his mark.
Marie immediately felt the weight of the jackass upon her, Josh not even waiting a second before he was already hoping over the jenny's body. The slapping of his cock over her butt cheeks sounding loudly as Josh clumsily tried to find its target, shaking his hips while grunting and breathing loudly right besides the her long ears.
At that moment, Marie's mind was fully occupied by the arousal and excitement of mating with Josh. Marie brayed, as Josh finally entered her. Both donkeys started to bray at the top of their lungs. The other donkeys, hearing that, began to bray as well, causing a defining sound of confusion.
Marie had gone beyond the limits of stimulation she could handle. She knew that she must be afraid and angry of being turned into an ass, but the pleasure of being a donkey was too good. Marie thought that there was only braying, why would there be anything else? it was all that mattered. All those worries, all that anger, nothing to be compared with the lust, the desire and the pleasure of braying and being a jenny.
"I am a donkey, and I love it. HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW! HEEHAW!", brayed Marie joyfully.
Later, when Josh dismounted her, a deep sense of acceptance and pride came over her. Though Marie still retained her memories, she knew that she could never be human in body or behavour, but she liked it, this would be her life.Then, she let out a bray of pride : "HEEEEEEEEEE HAAAAAAAAAAAWWWWWWWW "
