"HAWWWWW!" I brayed, unable to stop the donkey's call from escaping. My face went red and the laughter rolled over me.
The Madame's hands came over my shoulders and massaged them gently. My body felt warm and itchy and odd. I looked down at my hands and saw the middle and index fingers merging along with pinkie and ring; the nails of either getting darker and heavier.
"Mind if I make an ass out of you?" she whispers in my ear which was now starting to ache and grow.
My mind felt woozy and things were a blur. Her hands went down my back and to the front of my jeans, undoing my belt with deft fingers.
"Seems our boy Jerry here is a donkey at heart," she announced.
My pants fell to the floor around my ankles. If nothing else, my cock felt hard and fuzzy and numb. At least by being a donkey, I'd have that equine length. Things aren't all bad.
With a tug, my boxers were off and the cool air send a shiver through my body. More laughter but I was hung donkey at least. But as the laughter didn't subside, I had to know why. Looking down, the feelings were misplaced.
My cock was hard but barely more than a worn down, fleshy numb being pulled into the leathery grey lips that took up most of my crotch. I could see my testicles there and felt so sick in my gut when they pulled into that foreign looking sex. It dripped and pulsed and caused me to want to pass out.
"Seems Jerry here is a Jenny at heart!" she joked.
My hands felt so heavy now with all the feeling of my fingers gone. I tried to walk but my hips felt distended and the twist of my guts had me down forward on my new hooves.
I had to get a grip and think. "Stop this! Please, I don't want this!" I pleaded, trying to move but my shifting and cracking frame made it hard.
"Your body sure wants it!" she joked as my hips cracked and shifted, my ass reformed and swelling under a quickly growing grey tail.
I shake my head, my ears flopping side to side. "I'm not, no," I say again, hoping against hope.
Sneakers burst open, bones and muscles moved and changed until my lower half was a hairless jenny's. That I had this in me... how could it be? With every breath my chest and gut grew. My ribs swelled out, my insides grew, what were likely my ovaries came into being near the rest of the squirm of changes in me that stripped my humanity away. Even the smells coming from the asshole under my swishing tail were fit only for a barn.
People took pictures and teased while the Madame talked to her stagehand. I wanted to run but the changes weren't stopping.
I smelled something then that was odd but familiar in the same sense. The clatter of hooves and some brays and another donkey was brought out from the back.
"Ladies and gentlemen, meet. Stacy. She was a lovely girl who was a jackass at heart from a previous show. Might as well introduce her to Jerry, don't you all think?" Madame helped lead the big beast over behind me until I felt a wet nose at my backside. The flutter in my heart prickled my skin and grey hairs were sprouting all over me.
From the neck down, other than the ears, I was a jenny- in heat- and in my head still terrified that this was happening. My legs nearly buckled under the weight that suddenly fell on my back. I heard snorting and braying and it hit me. I was being mounted.
"Come on, folks. Let's cheer Jerry on here. Three, two, one, 'Jerry the jenny, Jerry the jenny,'" and that's all it took for the chant to be taken up.
I grimaced and teared up, mumbling "please" and "don't" over and over but was drowned out by all the cheers. The donkey cock I thought I had pushed its way into me, making me gasp and let out a bray. My neck popped and grew with every inch slid in me. Stacy nipped at my neck as a dirty main grew and my mostly human head was at the end of a jenny's body.
The donkey's balls slapped against my hindlegs once he was buried all the way and then the hard, steady thrusts came. My face was aching and it hurt and I knew what was coming. I was being fucked into this body now. My nostrils flared and my teeth clattered out of my mouth. Face pushing out, my wheezing breaths were long brays.
Lowering my head, hairs sprouting, I tried to accept it. There was no escaping and looking down at the hooves that were mind, hearing and smelling the thing on my back, I could only understand this was reality now.
"I'm a... a... a jenny," I lament with a sigh, causing the Madame to smirk, even if she was the only one to hear it.
No sooner had the changes ended than a flood of seed was dumped into me. It dripped down my sex and left me shaking.
Claps and more cheers as I panted and Stacy was led away.
"Thank you folks. Jerry here will be a proud mommy soon enough so give him some applause as well!"
