Nick Wilde and Judy Hopps moved in together and they were very happy. The shared apartment was small and cramped but Nick didn't mind being so close to Judy, and Judy enjoyed having her fox so close to her all the time. She enjoyed it so much, that it was beginning to corrupt her. She needed him more and more, almost constantly, and was addicted to his scent and body. As she began to change, her own body began to produce musk and pheromones that made Nick constantly horny.
One morning, as Nick and Judy woke up from a long night of fucking, Judy found she had changed even more. She felt younger and smaller, cuter, but also a lot sexier. Her butt was bigger, her breasts had grown, and she sported a pudgy belly. In addition, she now had a furry sheath and a fat pair of bunny balls. As the morning light began to wake her, Judy woke up and moaned, feeling Nick's cock sliding into her pussy, and her sheath and balls flopping about. "Mm, Nick!" she cried out, as he began to fuck her with his cock.
"Mmm, I thought we'd start the morning off with some morning sex," said Nick, grinning and holding Judy's hips.
"Oooh, Nick, this is perfect," said Judy, reaching back and rubbing her balls and sheath. She looked back at Nick and kissed him, before sitting back on his lap. Nick began to pound into her harder, making her moan and squeal.
"Mm, you look different today, Judy," said Nick. "Sexier..."
"Mmm, it's not just my looks, Nick," said Judy. "I'm your mate, I've got a cock too."
"A bunny with a dick? Wow, never thought I'd see that," said Nick.
"Oooh, and there's something else, too, Nick," said Judy.
"Oh yeah? What is it?" asked Nick, kissing her neck.
"I feel younger. I think I'm just 13 now, and getting younger and bigger..." said Judy.
"Well, maybe I'll fuck you until you're 9, then," said Nick.
"Sounds like a plan," said Judy. She bounced her hips on his lap, moaning and holding onto her fox as he fucked her.
"Mmm, how does it feel, getting younger while I'm fucking you?" asked Nick.
"Oooh, great! It feels so good," moaned Judy, leaning back against him.
"You're so sexy, Judy," said Nick, holding her tightly. He kissed her cheek, and began to fuck her harder and faster, until she was just a writhing, moaning little bunny girl. She came, squirting on Nick's cock, and her orgasm triggered his. He shot a load of cum deep into her womb, filling her up.
Judy moaned, and her ears dropped. A second pair of ears sprang from her head. Her eyes widened, and she giggled. "Oooh, wow, I've never had four ears before!" she exclaimed, and the two kissed passionately.
"Mmm, you've got so much cute going on right now," said Nick.
"It's all your doing, Nick. You're the reason for all this cuteness," said Judy.
Nick chuckled, and pulled out of Judy. She laid down, spreading her legs and showing off her cock and balls. Despite her tiny body, they were very large, full and warm.
"Oooh, you've got such nice, plump balls," said Nick.
"You do too," said Judy, and the two kissed. She rubbed their cocks together, moaning as Nick sucked on her nipples. Rich cream poured into his muzzle.
"Mmm, milk?" asked Nick, raising an eyebrow.
"Mhm, it's delicious, Nick," said Judy, grinning.
Nick chuckled and began to nurse from her breasts, holding her close. He could feel his cock getting harder, and his knot growing, while he nursed. Judy held him close, her own cock throbbing. She felt her breasts get bigger and fatter, her milk becoming richer. Her butt grew larger and larger, too.
After a while, Nick's mouth was full of Judy's creamy milk, and her tits were even bigger than ever. She smiled, and stroked his cock. "Oooh, it feels so good, having these big tits," she said.
"And you're so young, now," said Nick. Judy was only about six years old. Her balls were huge, and her cock was quite long, even for her size. She had an ass that would make anybody cum.
"I can feel you staring at me, Nick," she said, grinning.
"Sorry, can't help it," said Nick. "I'll go make us some breakfast, if you want."
"Yeah, sure, go ahead," said Judy, giggling.
Nick left, and went to the kitchen. Judy, meanwhile, sat up and started to stroke her cock. She began to moan, rubbing her shaft, her huge balls swinging back and forth. She looked out her window and thought about how perverted it would be for more adults to lust for cubs like her. It would be even worse for her, too, because she had a penis.
The idea of being a pedophile excited her, and she began to stroke her cock faster. "Mmm, yes, fuck me, you pedo," she whispered, stroking her cock, and squeezing her huge, fat balls.
"Yes, yes, yes!" she moaned, pumping her hand along her cock. Her cock began to twitch, and she started to shoot a huge load of thick, hot, creamy cum out the open window. The smell of her cum wafted through the air, and the whole neighborhood would soon reek of a horny, sexed-up, little Judy. Judy hoped the smell would work its magic.
After a few minutes, Nick brought a tray of food back to the bedroom. "Alright, Judy, breakfast is ready," he said, laying the tray down on her lap.
Judy giggled. "Thanks, Nick," she said, and the two kissed. They dug into their food.
While they ate, they looked out the window at the mess of Judy's cum in the street, and on the playground next to their building. "Wow, that's a lot of cum, Judy," said Nick, chuckling.
"Hehe, I know, I got a bit carried away," said Judy.
"No need to apologize, it's kind of a turn-on," said Nick, smiling.
"Really?" asked Judy, smiling back at him.
"Sure, why not?" said Nick, and the two shared another kiss.
They finished their meal and went outside. As they walked, Judy was delighted to notice a couple of adults sniffing her cum and looking at her, then at their partners or children. They were all starting to become a bit perverted, and that made her so happy.
As she and Nick reached the park, they saw a group of children playing soccer. One of the girls on the team was a young, blonde-furred, bunny named Jenny. She was the cutest thing on the planet, and Judy could tell that the way her clothes strained on her young body that she was developing rapidly. The bunny already had a big butt like Judy had.
Judy licked her lips. "Hey, Nick, how about we watch those kids play a little?" she asked.
"Sure, I'm up for that," said Nick, and the two sat down and watched the children.
After a while, however, Judy noticed something odd. The children seemed to be getting taller, and their voices were becoming more feminine. They were changing, and becoming younger, and sexier.
"Nick, are you noticing what's going on with the kids?" asked Judy.
"I think I am," said Nick. "Are they becoming more attractive?"
"Yeah, and I'm making their parents become pedo's for them."
"That's really weird," said Nick.
"But isn't it kind of hot, too?" asked Judy.
Nick grinned and nodded. "Yeah, definitely."
After the game, the team and their families went home. But Nick and Judy still stuck around, hoping that they would find some action.
As luck would have it, their luck turned.
Judy spotted a mother and her daughter walking by. The mother, a rabbit, was quite attractive, and Judy could tell that she was aroused by the smell of Judy's cum. The daughter was young and sexy, with a butt bigger than her mother's. 
"Hey, Nick, check out that girl," said Judy.
"Yeah, she's really hot," said Nick.
"Wanna go talk to them?" asked Judy.
"Sure," said Nick. The two walked over to the mother and daughter, who stopped.
"Hello," said the mother.
"Hi, my name's Judy, and this is Nick. We were watching your daughter play soccer," said Judy.
"Oh, I'm Mrs. Vix, and this is Jenny. Thanks for coming out," said Mrs. Vix.
"Of course, your daughter is amazing," said Judy.
"Thank you. Jenny's a really special little girl," said Mrs. Vix, who was beginning to stare lustfully at her own daughter's ass.
"So, Jenny, how old are you?" asked Judy.
"Six, I just turned," said Jenny.
"Aw, you're such a cutie. I'll bet you've got your mom chasing you," said Judy.
Jenny giggled and nodded. "I love her, she's the best."
Mrs. Vix blushed, and looked away.
"You're so lucky to have such a sweet mommy, Jenny," said Judy, reaching down and cupping Jenny's butt. Jenny gasped and moaned softly.
"Mmm, your butt is so soft," said Judy. "And so sexy..."
"Thank you," said Jenny.
Mrs. Vix was trying not to watch, but was failing. She couldn't help but notice her daughter's ass, and the way it moved when Judy touched it. Judy was making her attracted to her own daughter. She felt deeply perverted, and that made it even hotter. She knew this wasn't right but didn't want to stop it. She was starting to really enjoy it.
"You've got a really nice butt, too, Mrs. Vix," said Judy. "It's almost as big as your daughter's."
Mrs. Vix blushed and nodded. "I've been working out."
"That's great, I'd love to see it," said Judy.
"Yeah, mom, show us your body," said Jenny, smiling.
"U-uh... okay..." said Mrs. Vix.
Judy grinned, and began to undress Mrs. Vix. First, she pulled down the older rabbit's shirt, revealing her large, sexy, tits. Had they grown bigger? Judy could have sworn they were smaller earlier.
Mrs. Vix blushed and giggled. She wasn't wearing a bra, and her nipples were very erect. "Ooh, Mrs. Vix, you're such a horny mommy," said Judy, rubbing the older woman's belly. "Is that for your little girl?"
Mrs. Vix moaned and nodded.
"Show us, mom," said Jenny.
Mrs. Vix lifted her skirt and showed off her panties. They bulged with a new growing bunny sheath and balls.
"Oooh, wow, your balls are huge!" said Judy.
"Yes, and my cock is so hard," said Mrs. Vix.
"Let's have a look, then," said Judy, and pulled the older rabbit's panties down. She gasped. "Oh my goodness, your dick is beautiful," she said.
Mrs. Vix smiled and stroked her cock. She had a massive, long, hard cock, and a pair of balls that were each the size of soccer balls. "Thank you," she said.
Jenny smiled and began to lick her mother's balls. She sucked on her cockhead, moaning softly.
Judy and Nick both enjoyed the sight of Jenny sucking her mother's cock. Judy rubbed her own cock, and Nick watched, stroking his.
"Mm, Jenny, you're a good little cock-sucker," said Mrs. Vix. She smiled, and pulled her daughter up. The two kissed, and she pushed her daughter down on the grass. "Let's get these clothes off, hmm?"
"Okay, mommy," said Jenny, and she began to undress. She seemed even younger and more fertile than a few moments ago. Her tits were now huge, her belly was pudgy, and her butt was even bigger than ever.
Mrs. Vix stared hungrily at her daughter. She pushed the girl down, thinking about how much a pervert she was now. How her body had changed, how her mind was now filled with lust for her little girl. She couldn't care less. She was a horny pedo now, and she was loving it.
She grabbed her daughter's ankles, and pulled them up to her chest. She pushed her cock deep into her daughter's cunt, fucking the young girl.
Jenny moaned and squealed, as her mother fucked her. She felt her womb go into overdrive. "Oooooh, mommy, yes, fuck me! I love you, mommy!" she cried.
Mrs. Vix leaned in and sucked her daughter's tits. She was getting hornier by the minute, and wanted nothing more than to breed her daughter. To make the little girl carry her child.
Jenny's pussy clenched on her mother's cock. Her womb was ready to accept her mother's cum. "Ooooh, mommy, cum inside me, please!" Her voice sounded younger and squeakier by the moment.
"Mmm, that's it, baby girl, take mommy's cum!" said Mrs. Vix. With a moan, she came, flooding her daughter's womb with cum. Jenny cried out in ecstasy, as she came, her pussy squirting onto her mother's cock. She came hard, and her belly grew.
After the two finished, Mrs. Vix smiled at her daughter, and the two shared a kiss. Jenny's belly grew and grew, and she was eager to give birth.
Judy smiled, and stroked her cock. Nick stood by her, and held her in his arms. The two were both deeply turned on by the sight before them.
Mrs. Vix stood up, and looked over at Judy. "Come here, Judy, let's see what that cock can do," she said.
"Mm, yes, Mrs. Vix," said Judy. She walked over to the older rabbit, and her cock rubbed against Mrs. Vix's belly. Judy was so virile that the older bunny was immediately impregnated. She gasped, and her belly grew, swelling to the point where it nearly reached her breasts.
"Mmm, wow, I can feel your child growing inside me," said Mrs. Vix. She giggled, and looked at Nick. "You too, fox."
"What do you mean?" asked Nick.
Mrs. Vix smirked, and pushed Nick down onto the ground. She climbed on top of him, and her pussy engulfed his cock.
"Mmph, ooh!" moaned Nick.
"Mmm, your dick is so huge," said Mrs. Vix, as she rode him. She bounced up and down on his cock, her butt jiggling, and her cock flopping about. Her seed dribbled onto Nick's belly, making it swell fat and pudgy and full of her kits.
Nick moaned and gripped her hips, fucking her hard. He felt his knot begin to form, and he began to thrust deeper and harder into her.
"Oooh, yes, you're so sexy," moaned Mrs. Vix, as she was filled with Nick's warm, thick cum. She gasped, and her belly swelled. She was impregnated, and she was happy.
"Mmm, thank you, Mrs. Vix," said Nick, smiling up at her. He felt he was going to give birth at any second.
The older rabbit smiled back, and kissed him. "Thank you, too."
Jenny came over, and cuddled up next to Nick. She kissed him, and her belly swelled. All three of them fantasized about their young children becoming perverted and making other adults into pedos for them.
"I'm going to have such a wonderful family," said Jenny.
"That's so true," said Judy, grinning.
"Yes, and they're all going to be so perverted and sexy," said Mrs. Vix, smiling.
"Absolutely," said Nick, and the four kissed and cuddled.
As the four cuddled and made out, other children in the area began to become attracted to their mothers and fathers.

Safu the mouse girl was on the playground nearby when she began to feel the influence of Judy, Jenny, Nick and Mrs. Vix. At first, she was just having fun on the swings, but then she began to notice some of the adult rodents around her staring at her.
They were all looking at her, and it was making her feel sexy and cute. Her body began to reflect those feelings and grow sexier and cuter. Her breasts grew, her belly swelled, and her butt began to get bigger and rounder. She was getting horny, and she was loving it.
Safu got down from the swing, and approached one of the male mice. "Hi," she said, smiling and twirling her hair.
"Hello," said the male. "How old are you, little one?"
"4," said Safu. "And you?"
"15," said the male.
"Oh, wow," said Safu. "Do you think I'm cute?"
"Of course, you're the cutest thing on earth," said the male.
Safu smiled. "Wanna see me naked?"
"Definitely," said the male, and the two went behind the equipment.
Safu began to undress. As she did, her body continued to change. Her tits grew, her hips became wider, and her butt became plumper. Soon, she was naked and fully developed.
