Meanwhile, Josefina and Jamie find the girls

Josefina led Jamie towards the barn, humming happily and holding herself back by sheer **** of will. Josefina knew exactly what they would find once they reached the building, and while she couldn't predict how Jamie would react, she already knew how it would end. She had to keep herself from taking the cute redhead right then and there, especially when the short girl's breasts were jiggling slightly with every step. Josefina's cock longed to reemerge, but the futa hucow restrained herself.

"What kind of work are you doing in the barn?" Jamie asked, momentarily tugging Josefina's thoughts from what the girl would look like once she changed.

"A change in production, we found a much more enjoyable way for the cows to give milk. It should make all the difference," Josefina lied smoothly, somehow coming up with the fib off the top of her head. Jamie, a strong supporter of animal rights, ate it right up though, her expression brightening.

"That's wonderful! The dairy business has never been overly cruel to animals, but every improvement is progress. Can I see exactly what you're changing?" she asked eagerly, looking at her aunt with excitement.

"Of course, you can even see it first hand," the disguised futa said, very much looking forward to giving her niece that experience.

"Awesome, thanks Auntie! Is it right in here?" Jamie asked, her hand wrapping around the door of the barn. Josefina gave her an encouraging nod and immediately began pulling her shorts off once the younger girl had turned away and started pulling the barn door open. "Maggie, are you in here? Why aren't you answering your-"

"Moooooo....." A long moaning moo cut Jamie off and the redhead's eyes widened when she saw the three huge-titted girls being milked in the barn. Two of them were unfamiliar, their bodies half bovine and half human, but the third, with her long blonde hair and pretty face, was all too recognizable, even with her massively changed body.

"Maggie...?" Jamie asked hesitantly, barely believing that the gorgeously curvy hucow in front of her was her cousin. The blonde slowly at the redhead, rising out of the stupor she had let herself sink into and eventually recognizing the girl.

"Jamie, hi. Mmmhh, sorry, I'm a little busy, or I'd come hug you and suck on those nice titties. Don't worry though, it looks like Moooomma is going to take goooood care of you. Oh, I'm gonna...gonna.....moooooo...." Maggie shuddered and moaned through an orgasm, but Jamie's attention was stolen by the log of hot flesh that was suddenly pressed against her bottom. She knew what it was, though she couldn't believe who it was attached to.

"You're a tease, you know, strutting around in front of me like that. I bet you want this, don't you? Want my fat dick in that ass and filling you up to make your boobs even bigger. I can't wait to hear you moo for it," Josefina whispered to Jamie, rubbing her cock against the younger girl's butt while her hands slipped under fabric to massage supple, youthful flesh.

Jamie wanted to fight back, but the smell coming from her aunt was overpowering. Something about it made her just want to bend over and present herself for rutting and breeding. The insidious thought wouldn't leave her alone either, no matter how hard she fought it, leaving her rooted in place while her clothes were pulled from her teen body.

"You're already wet? You really do want this shaft inside you, don't you?" Josefina asked the motionless Jamie, watching as thin strings of fluid stretched from her panties to her labia before snapping. The redhead suddenly realized she was very naked, except for her shorts and underwear around her ankles. Still, it only mattered because she could now feel exactly how hot the dick poking at her ass was, along with how thick it was and the slick feeling of precum leaking onto her skin. Her head was awash with the powerful scent of Josefina and any resistance to what was happening to her was gone like dust in the wind.

In fact, she barely needed any help in bending over. The slightest push from her aunt had her bending over slowly, going further and further until her torso was parallel to the ground, the meaty orbs on her chest hanging down slightly while her butt was perfectly on display for her aunt...no, the bull behind her. The smell of her, of the cows strung up in the barn, of fresh milk, invaded her senses, pulling everything away and making her so very wet. The hot log on her ass only made it worse, made her need it more.

Jamie whimpered her desperation and felt the dick nestled against her butt throb in response. She raised her little teen tushie a little more, eyes barely able to focus. She didn't know why but she desperately needed sex like she never had before.

"Oh, look at you, prefect little breeding stock. I bet you'll have so many little calves. Fuck, you're not even a virgin, you little slut," Josefina moaned as she pushed inside her niece, sliding in easily and without resistance from a hymen. Someone had fucked Jamie before, but Josefina didn't care. She knew she'd be the last one to feel those depths anyways. None of that mattered, of course, once Jamie let out a shuddering moan that sounded suspiciously like a moo and Josefina's rational disappeared into a frenzied need to mate and breed.

The two women moaned and bucked against each other, both yearning for the climax even though they had just started. Despite not being a virgin, Jamie's pussy was still extremely tight, squeezing around Josefina's bullish cock with fearsome intensity. Pleasure wreaked havoc on her and precum seeped out of her dick, slowly infecting Jamie. The young woman's body was already succumbing to it, her skin flushing further and her hair brightening in color, becoming an even more vibrant red. Her legs trembled under the **** of Josefina's thrusts, but the changing girl **** herself to stay standing, if only to ensure a hot load of cum was deposited in her womb as soon as possible.

"Ohh, ooo, mmm, ah, mmph, nngh, mmmmmm~!" she moaned, her breathing growing heavier with each thrust that bottomed out inside her. The urges of another voice in her head, one that encouraged her to just give in and be a cow slut, steadily grew, matched by the increasingly meaty slaps of flesh on flesh. Her bottom was growing and widening, ensuring she'd have a gorgeous pair of hips that marked her as ideal breeding stock. Naturally her breasts grew as well, swelling from both an increase in size and a pressure from inside that she knew was her milk.

The feeling was nearly strange enough to scare her, but it also felt perfectly natural. Normal. Good. 'Could fight. Why bother?' she asked herself, thoughts no longer flowing as easily as they had before but still making perfect sense to her. 'Feels good. Feel even better. Be happy cow. Milked and bred. Babies to nurse. Be with Maddie. Be cow. Become cow. Happy cow. Moo. Cow moo. Yes, moo.'

"Moooooo!" Jamie called out, her tongue vocalizing the acceptance she had come to in her mind. The part of her mind that told her how nice it would be to give in expanded, with the rest of her body following until her physical and mental states perfectly reflected each other. Her tits were huge, wider than her torso and just barely bigger than her head, dripping with milk already. Her hips popped, finally rounding out to the perfect fuckgrips they had been working towards. Her arms and legs remained thin but perfectly smooth, bereft of any flaws. Her burning red hair came down to her waist and a thin tail with a tuft of hair sprouted just beneath its ends, waving happily while Josefina continued to pound her. The final changed slammed into place once her aunt's cum finally filled her, lighting up an orgasm from her transformation and knowing she had been bred. The last of her human worries vanished as two tiny horns and cow ears sprouted from the top of her head, solidifying her place as the newest cow in Josefina's herd.

"Good girl," Josefina panted once she finally came down from her peak and had pulled her still hard shaft out of her transformed niece's pussy. "I'll fuck you more later, but first we have to get you in place and then go get your mom and sister. I'm sure they're already milky cows like you just waiting for a good fucking. Come on, you can go next to Maggie."

"Moo!" Jamie said and followed her new bull without complaint, not really recognizing the words coming out of her but understanding their meaning. She jiggled happily as Josefina locked her in place and moaned once the pumps went to work on her breasts, drawing orgasmic spurts from her leaking tits.

"I'm-ohhhh...glad you're my slut-sister, Jamie," Maggie groaned, shaking her huge teats to let her milk flow better.

"Moo!" Jamie said brightly, agreeing wholeheartedly and looking forward to the next time her aunt would come and breed her.
