Jennifer's hands and feet were touching the straw floor until they transformed into black hooves. She still had her curvy womanly form. When Jennifer felt Ben enter her still human vagina she realized her hands and feet were hooves. Jennifer's body twitched and spasmed with animal lust as Ben did.
At the end of the act, with her hourglass figure barreled and her tight little ass bloated, Jennifer realized she was a donkey as Ben. Then, Jennifer saw Amber very ashamed of what she done and began to cry as Ben shot his last seed into her donkey body.
By the fear, Amber had her mouth covered by her hands during all Jennifer and Ben's mating, trying to not shout.
"HEEEEEEEEEEEE HAAAAAAAAAAAAAAAAWW!" , Amber covered her mouth just as Jennifer had at the first sight of her ears. Tears began welling up in her eyes.
As if driven by another instinct, Amber fell to her hands and knees, and began to bray again, "Hee Haw! Hee Haw! Hee Haw! Someone help meeee!!! HEE HAW! " Jennifer looked around frantically, unsure of what to do.
There before here was her best friend on all fours braying and acting like a mindless donkey as she had done before.
For a moment, Amber’s face scrunched up, like she was fighting to hold in another rasping bray. When Amber lost the battle within herself, her mouth opened wide, lips revealing her teeth, among which were two laughably large buck teeth.
As if triggered by her shame, Amber's spine began to elongate, faster than her ears ever had, and before she knew it something was bunching up in the seat of her panties. Amber tried with both hands to reach behind her to lower her pants, just a little, but each time she took her hands off the ledge, she could feel her weight pulling her back onto all fours.
Amber had to put her hands on her waistband, and in one swift motion pulled her pants and underpants down to her knees. As soon as she did, she saw what had been causing her so much discomfort. There, protruding from Amber's tailbone, and hanging down over her ass was a donkey's tail, swishing and flicking.
Jennifer tried not to laugh at her again, but found it increasingly difficult given the sight before her. Amber's bare ass adorned with a donkey tail seemed humorous to Jennifer, and before she knew it erupted in braying laughter "Heee Haww! Heee Haww! Heee Haww! Heee Haww!"
Jennifer and Ben stood there and watched as Amber kicked her legs out like a wild donkey each time she tried to stood, her tail flailing wildly with each attempt.
Between Jennifer’s ears, a patch of dark hair begin to form, stretching from the start of her hairline, and continued over her head, and began to spread down her spine. Jennifer could feel the itching and burning spread down her neck, and no amount of rubbing or scratching could alleviate it.
"I have a mane!" Cried out, Amber ran to a mirror and saw the line of dark fur running down the middle of her head. She turned around to see that it continued down her neck and back. She quickly tore off her shirt and her bra, to see that it continued to trace her spine, leading to a small furry lump at the base. By removing her shirt it became apparent to both women that Jennifer's nipples had turned to a dark shade of skin, no longer the soft pink they once had been.
" HEE HAW!!! Look at meeeeeee!"Amber cried, looking herself over for any other changes that she'd undergone unbeknownst to herself.
Jennifer brayed again when she noticed another change on Amber's body that she had neither felt nor known about.
"What, what is it this time!?" Amber asked, quickly swiveling her head back and forth trying to look over herself, her ears swaying over her head.
"My lips..." Amber whispered, mortified looking in the mirror that under her tail and between her legs, her lips had become swollen and dark, and pulled themselves closer to her anus. Her once human genitals now resembled, and had begun to smell like those of a jennet.
Her once stylized pubic hair had been replaced by a thick coat of coarse fur too. Then Amber watched her fingers wrench themselves into fists, before finally closing for the last time as they became hooves. Amber looked through her legs and passed her tail to see that the same thing was happening to her feet. She tried to walk, but she could only manage to trip over her clumsy hooves. The sound of her hooves clopping against the floor was soon drowned out by the sound of Amber's panicked murmuring and hyperventilating gave way to more braying.
"Heee Haww! Haw! Heeeeeee haaaaaaaaaaaww!" Amber bellowed out, as more fur crawled across her naked body.
Jennifer and Amber let out countless loud brays as what was left of their humanity slipped away, leaving two young jennets in their place.
Ben was pleased.
