You are Larry, a bright college student. You bought a pack of pills from a sleazy woman. She said they would turn you into a horny donkey. You stand in your bathroom in front of the mirror and take one of the donkey pills. You don't feel a thing. Five minutes later you go to take another pill and realize there is nothing left in the bottle. Have you taken them all and haven't noticed?

Suddenly you hear a knock on the door. It's your stepmom, yo you open the door.

"You're not supposed to be in here that long" she says.

"Sorry, Jenny. I think I made a mistake and took pills that will turn me into a donkey", you answer, feeling quite foolish. Why did you say that?

"Are you OK, Larry?"

"Yeah, I'm fine. Just bought a pack of pills that don't do anything. Here, look at this." You show her the empty bottle.

"What do the pills do?"

"I dunno. A lady gave them to me and said they would turn me into a horny donkey, but I think that's just in her head." Something about your story doesn't seem to add up. You have no idea why you tell your stepmother all that, but the words just seem to flow out of you.

"You look a little red around the gills. Are you sure you're OK?"

As your stepmother looks at your hands, you see gray fur spread over your forearms. "Jen, do you see what's happening?"

Your stepmother steps back from you and screams in shock.

"Oh no, I'm really turning into a donkey, Jenny!" You let our a harsh, loud bray "Hee-haaw!".

You look up at your stepmom's horrified face as she tries comfort you in some way.

"Jenny, I don't want to be a donkey! Hee haaw!" You bray some more and feel soggy fur along your spine. Your stepmother's eyes are bulging out in horror.

"Please, don't make me be a donkey! Hee haaw!" you bray.

"Hee haa... hee haa... get away! Get away!" Jenny shouts, backing away from you, clasping her hands over her mouth.

"Jenny, why are you... hee haw... braying, too?"

"I'm sorry, Larry. I... hee haw... hee haa... I can't help it." Her face starts to take a dopey, unfocused expression

The gray fur is all over now. You look in the mirror and are dismayed by what you see. Your features seem to broaden, your nose bluding out and your teeth growing.

You say "Jenny, we are both turning into... hee haw... donkeys! Hee haw!"

But your stepmom isn't helping matters. She is howling in laughter. "Larry, I can't help it. Hee haa... hee haw..."

You can't take it anymore. You see her ears getting long and covered by gray fuzz, like yours. You look into each other's eyes and let out a loud bray.

You feel the changes crawling down your body. The gray fur crawls down your body and into your clothes. Thick nails grow out of your stiffening fingers, and your teeth turn yellow. Your mind begins to fill with thoughts of feeding and... You turn around in embarrassment as you feel your pants suddenly getting very tight. You can't face your stepmother and the changes you are going through. You feel your pants suddenly get even tighter around your waist as you stumble forward, falling to the tiled floor

"What's wrong, Larry?" Jenny asks, concerned.

"I dunno. I have to... hee haa... go..." You stand up and feel your stomach protrude out of your shirt front. You look down and see your new fat belly poking out of like the gut of a mini-pony, taunt and furry. You feel your face shift up as your nose runs constantly, dripping snot down on your shirt.

You try to open your pants to relieve the pressure while avoiding your stepmothers gaze as her changes continue, too. You pull at the button on your jeans and give it a tug, but the button won't budge.

You say "Oh god! Hee haaw! Too tight!"

"What's wrong?" Jenny asks, looking over your shoulder, her donkey teeth poking out of her mouth

"I need to go to the bathroom," you say.

"Oh," she replies. "Well, come here."

"No, don't! " You turn your head away as your stepmother moves towards you, too late. You feel the wet warmth gurgling up through the tightening of your pants.

"Hee haw!" you groan. "Oh dear!" You quickly turn your head and look away as you feel your stomach get even fatter. "Ahhhhh! Hee haaaw!".

Your stepmother's belly rumbles as she snorts and snuffles up close to your ear. "I'm so sorry, Larry," she says, her breath making you giddy. "You smell... soo... haaawt!"

"Get way from me... hee haaw! Jenny!" you shout while trying to get your pants ofs as they cut into your swelling groin.

"I'm so sorry, Larry. I can't help it... aaw... hee haa..."

You turn around and nearly fall over as your pants completely drop down around your ankles. "Heeeeee!" you groan as your belly churns uncontrollably. You look at your stepmother's face again, horrified by what you see. She's not human anymore.

You say "Jenny, your face!"

Your stepmother looks down at you with her new black donkey eyes and snorts with laughter. "Heeeeee!" she laughs. "Hee haaaw! Hee haaaw!"

"Please Jenny, your ears!" Your stepmother's long gray ears twitch as she brings herself closer to your face. You can smell barnyard scent in her breath.

You try to back away as you groin stirring again. That scent.. that musk... a jenny in heat.

"He hee haaaw! Hee haaaw!" your stepmother laughs her belly shaking.

Your boxer shorts have tightened so much that you can feel every single heartbeat.

"Oh for... my nuts!" you groan, feeling your testicles start to swell.

Jenny sniffs at your growing genitals and snorts in pleasure "Hee haaaw!"

You bray in fear. "Hee haw! Oh, no Jenny! Don't even think about... hee haw!" Your belly grows tight as the warm gurgling bubbles inside of you.

"He hee haaaw!" The donkey woman licks her rubbery black lips as she moves closer to you. He tongue seems to be huge! "Haaw! Haawt donkey boy. Hee haw!" she slurs.

You groan, trying not to stare down at your expanding balls or her tits.

"Good..." your stepmother says, her nose flattening into a donkey snout. "Haawt! Good... good..." she neighs, smacking her lips. She looks down at you and opens her mouth as she leans forward. Drool runs down her chin.

You feel your darkening cock starting to rais against your will. You groan as you feel your swollen, darkening member grow out of your boxers.

"Oh god no," you wheeze, as your Jenny grunts with satisfaction. She moves forward and grabs your shoulder as her mouth closes over the top of your head.

"He hee haaaw!" she snorts, blowing out warm air against your dick.

You flinch as her intoxicating animal scent hits you. You feel your hands go limp as she gives your donkey dick a lick.

"Oh that's right," Jenny laughs. "Don't worry. You're a cute little dum-dum now. He hee haaaw!"

You feel her words resonate in your head as you lose a part of your human intelligence to the horny donkey inside of you.

"Jenny!" you groan, as you begin to feel the horny, territorial donkey inside of you start to stir.

"Oh yeah," she snorts with satisfaction. "That's how I like my donkey." Your belly begins to rumbling as you struggle to hold back a laugh.

"Don't worry, dum-dum," your she says with a smile. "We both... hee haaw... be dumb donkeyth... fucking."

The horny donkey stirs within you as you feel an uncontrollable urge to.... "Heew haaw! Need to breed! Tho horny!", you scream.

You watch, helpless, as your stepmother's body grows hairy and a large.

"He hee haaaw!" she snorts, blowing the hot steam out of her ears. A thick grey tail swishes behind her. You get closer to her, wanting to smell her musk while your growing donkey cock drips precum. Jen snorts as she head butts you aside. She grabs your neck with her stiffening hands and stares into your eyes.

"Dum-dum," she says, before planting an sloppy kiss on your broadening flank. "Hah! Haaw donkey assth!" she says, licking your fur. "Jackath!"

You press your entire body against hers, rubbing your sides against hers. She gets behind you, grabbing your massive testicles. She squeezes them as you feel the donkey cream run down your shaft.

"Mmmh... good donkey," your stepmother hums.

You can't help but to lean into her kneading hands while letting out a loud, lusty bray. Your jenny smiles and starts massaging your flanks, moaning as she does so.

"Ah... good hawwt boy," she sighs, looking up at you with a buck-toothed smile.

"Ah! Haaw!" you groan.

"That'th it, dum-dum donkey." your stepmother grunts.

Your stepmother steps behind you, grabbing your long, thick donkey member. She slowly begins to slide over it, making you moan as you embrace your growing beasthood.

"Ah! Gaggh!" you cry, as she begins stroking your thickening donkey's head. As this new "you" embraces his beastly urges, your mind fills with bestial lust. You turn around and face Jenny's changing body, ready to mount her as soon as she gets down on four hooves. Her body's thickening and changing contour.

"Hee haw! Take me, my jackath" she brays. Your stepmother reaches her arms out, and you grab her shoulders as you stare into her eyes.

"Do it, do it, do it!" you pant.

You feel her lean down and press her thickening lips against yours. As your lips meet, you moan into her mouth, the taste of dirt and grass filling your own. As you embrace, you feel your stepmother's body growing more hairy, her belly bulging and twisting as it becomes like a horse's. You pull her closer, rubbing your bodies together as you embrace the bestial lust inside of you.

"Mmm-hmm! Take it, donkey!" your stepmother grunting.

You moan, your own lips parting as you take her animalistic maw. You start kissing her back, rubbing your bodies together as you feel your newly hairy chest rubbing against her smooth fur. Your stepmother shuffles, lowering herself as her hands push your legs apart.

"St-stop," you gasp as she gets down. The smell of animal heat your nostrils, and as your Jenny presents you her donkey ass you eagerly comply. You mount her as your jenny, like the jackass you are. Your mate looks at you as you grunt, pushing yourself into her body. You moan as her warm, wet hole envelops your throbbing member, and you push deep inside.

"Hee haw!" you grunt. As the two of you embrace and hump the dirt, you can't help but let out a braying neigh. "Ah! Haaw!" you bray.

"Gaggg...!" your stepmother pants. You look down at your her, as her hairy body morphs in front of your eyes.

"Ah! Moooommm...haaw" you moan. The sight of your stepmother's body changing completely into a donkey turns you into a feral beast, as you start to thrust into her deep and hard. Your thick, long member slides in and out of her warmth as you moan, feeling your mind breaking apart in the bestial bliss. You need to breed, to spread your seed across multiple female donkeys. Just think of the pure donkeys you'll father with this one. You feel hot liquid spurting inside of your jenny. "Haaa...maww....haaaaw!" you cry. Your own thick seed spurts inside of your mate, as you moan and growl, the animalistic feeling overwhelming you. You feel your mind breaking apart in the bestial bliss, and soon, you're left in the your own dirt with a massive sense of guilt, like a lead blanket on a freezing winter's night.
