Melina and her friends turned to see Gwen.
"Look who's talking, Gwenny Jenny." said Devora. "The girl who brays like a real ass. I have heard her in the restroom."
As Devora spoke, she slipped a hand into her rucksack and fumbled around inside.
Melina was furious, but soon she smiled thinking that she would hang Gwen from the tree like the other girl.
“Bitch wants to fight!” Karen spun round on her butt and crossed her legs to watch her best friend show the uppity bitch who is boss.
“A dumb ass like you can’t make me do anything,” Gwen grinned, she slipped a small grey water balloon from her bag and tossed it at Melina. The balloon hit her square on the shoulder and burst, spraying its contents all over her blouse and cheek. Melina spat out the little that got in her mouth almost immediately. It smelt and tasted revolting. She huffed. She’d need a shower and a change of clothes before going to the party but she was going to make sure that Gwen suffered for that prank.
Maybe making her a big wedgie and then naked her in the park will teach Gwen to respect your betters, Melina thought. Melina’s eyes flashed brightly and her face seemed to flush a furious red, for a moment it looked as if she was glowing, as if a powerful force was building within her, preparing to be unleashed.
“You will pay for...HEEEEEEHAAAW!” Melina shouted back, her words were cut short by an unrestrained and undignified braying. The powerful force building in her seemed to fizzle out pathetically like a damp firework. She felt her pants tighten and could hear a ripping sound of her sleeveless green shirt as her hips and torso expanded.
Her hair was forming a mohawk and her ears rocketed up to the top of her head, turning into brown furry donkey ears.
“Shit! HEEEE HAAAAAAAWW! Melina brayed, “What happens?”
Her pants and shirt were gone now and she could feel something, a tail, growing inside her panties. It grew so quick, as if it were trying to escape and it pushed her underwear down her thighs. Her now fur cover anus and pussy were on show. Karen and Devora were in hysterics.
"Damn it! What did you do to her, Gwen?" asked Devora.
"Nothing. Melina did all the job. If you act like an ass, you're an ass. "
Melina’s eyes darted about quickly trying to register all the changes, trying to gauge how far along she was. Out of the corner of her eyes, she saw fur was crawling up her neck and from her ears and hairline to quickly cover her whole face. Her mouth pushed out into an equine muzzle, her thick lips parted to reveal big goofy teeth. She realized she was beyond hope, already past the point of no return.
This wasn’t supposed to happen! Melina thought. She was a popular cheerleader. Cut from a different cloth to most girls and destined to be part of something greater in the future. But from that moment she’d just be an ordinary donkey.
