Petula found herself at the doors of an old wooden barn that stood separate from most of the buildings on the farm, curious she grabbed hold of the large metal handles on the doors and
with some effort pulled them open enough to enter.
Unbeknownst to Petula Jimmy was following her, half out off his attraction to her and half out of curiosity as to why she had wandered so far from the rest of the class.
It was dark inside the old barn, searching around with her hand Petula managed to find a heavy metal switch on the wall next to the door, flipping it the electric lighting in the barn flickered to life.
The barn was clearly no longer in use, made redundant by the new modern barns built in the main farm complex. Old miking equipment hung covered in dust next to half a dozen empty stalls, the occupants having long since been relocated.
Petula didn't know why but she felt drawn to this place, like she needed to be here, but having
moved to the middle of the room she suddenly started to wonder why she had decided to come
in here in the first place.
Poking his head into the barn Jimmy decided to announce his presence and ask what Petula was doing, but as he opened his mouth to speak, he stopped as he noticed something strange was happening. Groaning Petula clutched her stomach as it gurgled and started to ache, rubbing it she felt a tingling rapidly spread through her body, inexplicably she felt like her clothes were a bit tight, maybe she should tone down the tight pants from now on she thought.
As the pain in her stomach intensified Petula bent forward, the motion increasing the strain on her already tight pants, with a loud rip they split down the middle, partially exposing her already ample cheeks as they slowly swelled.
Surprised by the tear Petula reached back and felt her backside, and to her horror realised it was growing, turning around to inspect what was happening she came face to face with Jimmy as he stood in the doorway, an erection bulging in his pants.
"What the hell Jimmy! Eeguh!" Petula exclaimed, forgeting for a moment her situation, but she was quickly reminded when with a final gurgle of her stomach something started to push out of her crutch, squealing in terror she
looked down in horror to see what was clearly an udder push up her shirt, though small for now it was continuing to grow.
"Don't just stand there! help me, we have to get moooo!" Petula's word were cut off as the
sound escaped unbidden from her lips. "Oh god l'm turning into a cow" she murmured. "It's
alright l'm sure you'll be a cute cow Jimmy tried to comfort her, though he was definitely enjoying the situation.
"You're not helping Jimmy! mooo" as another moo escaped Petula lost her footing and with a gasp fell forward onto all fours, her shoes and socks had come off, revealing to the two that where her feet had been were now dark hooves, as she tried to push herself up Petula gasped in
horror as she saw her nails darken and expand, rapidly engulfing her hands and reshaping them, within moment they too were hooves.
Trapped on all fours Petula could feel herself getting fatter and fatter, though her pants had
partially torn her clothes were hanging on, making it harder and harder for her to breathe. Embarrassed but with no other choice she looked up a Jimmy, who still stood stunned
at the sight playing out before him, "you have to help me.. I can't... breathe... mooo...".
Hardly believing what he was hearing Jimmy sprung into action, seeing old metal shears hanging on the wall he ran and got them and within moments he was back. "Gasping for air Petula was already beginning to lose her human shape as her body became more and move bovine.
Leaning over Petula's still swelling body Jimmy careful began to cut along the back of her shirt, assisted by the cut her shirt finally gave way and fell to the floor. With another cut Jimmy freed Petula of her bra, which fell to the floor revealing that her boobs had disappeared, their mass having been absorbed into the growth of her still growing udder.
"Euuuh... my mooo.. Pants!" Petula cried. Stepping back Jimmy was just in time to see them fully give way, Petula's huge rear bursting forth, fat shaking back and forth, her asscheeks increasingly a blend of human and cattle. Unable to control himself any longer Jimmy dropped the shears and unzipped his pants, pulling his penis free he began to frantically masturbate, his dreams were coming true before his eyes.
"What the hellll arr yooou mooing?!" Petula slurred, her face having begun to pull forward into a muzzle, but she had bigger concerns as her transformation showed no signs of stopping.
As splotches of fur matching her hair began to grow all over Petula's skin Jimmy was greeted with quite the sight as her final item of clothing, her panties, gave way, snapping with a dull twang. The tail now growing from above her ass had cleary pushed them to their breaking point.
Looking down Jimmy saw Petula's pink pussy lips and petite butt hole, though they had shifted to face backwards they were still tiny and looked out of place nestled between her increasingly hairy ass cheeks. As the thought occured to him Petula's transformation responded and Jimmy began to stroke faster as he watched her asshole swell into a dark, meaty donut beneath her tail.
Petula's increasingly large tongue now hung from her mouth in uncontrolled pleasure as Jimmy watched her pussy lips begin to darken to match her ass. Petula's entrance began to pulsate as it darkened, growing wider and wider as it lost it's human shape, within moments it was nothing but a cow's vagina.
With some effort Petula pulled her tongue back into her stretching mouth. "Moooooo!!! Yoouuuu jackassss stooop fappinggg!" she demanded, but all she got was a grunt in response as Jimmy came, cum splattering on her now enormous ass.
As if responding to his climax Jimmy's powers surged and the last of Petula's changes seemed to hit her all at once. Her arms and legs stretched and thickened into a cow's, her neck bulged and lengthened as horns grew out the sides of her head next to her increasingly large ears, and her udder finally reached its full size, lightly pressing against the sides of her legs.
"Mooooo!!" finally Petula came, as a spray of bestial juices squirted from her huge bovine vagina, the dark flesh desperately winking. After recovering Petula looked back sheepishly and saw Jimmy pulling his pants off, she had cum all over him she realised with embarassment. "Mooo..." as she went to apologize Petula realised with shock she could no longer speak.
"Fuck that was hot...you were hot before, but as a cow, wow" Jimmy suddenly exclaimed with a laugh. Petula despite herself found she was delighted by his words, turning around she looked down at his penis, it still lightly throbbed as it stood at full mast, she knew it was wrong but she increasingly found herself wanting him.
Embarassed but with a growing attraction to Jimmy, Petula felt her vagina squeeze as she thought about him fucking her with his big fat bull dick, her udder bloated with milk as she bore his calf. Snapping out of her fantasy she had to remind herself Jimmy wasn't her bull, he was still a human. "Moooo..." Petula exclaimed frustrated.
As it occured to Jimmy that he might have caused Petula's transformation he decided he would have to give his theory a test. As Jimmy's power surged, Petula's new fantasy might just be about to come true.
