Jizza Zoo

The Jizza Zoo Conservation Project

Steph crashed through the bush behind Sefton. Steph's heart was hammering and she was being scratched and snagged by branches as she cradled her camera against her chest. It was all she could do to keep up with Sefton, since the tracker had a natural gift for effortlessly slipping through the dense jungle with only the odd swipe of her machete. Steph nearly tripped, but somehow managed to keep her feet, and barged right into Sefton's back. Sefton looked back over her dark shoulder with a look in her eyes that told Steph that they were already too late.

Steph, already fighting back tears, stepped around the tracker and into the clearing.

She raised her camera and started shooting.

***

Hours later Sefton and Steph were sitting in a dirty makeshift bar drinking beers over prints of Steph's most recent photos. Sefton worried about the young photojournalist, since the pale mousey-haired woman was just silently glaring at the photos: the ghastly pictures of a half dozens murdered tigers, flensed, their skinned bodies still steaming, the poachers long gone. For Sefton who had been working as a guide and tracker in these jungles for years it was hardly new, and as much as every killed beast saddened her, she had grown too accustomed to it to be crushed. It was hardly the first time for Steph either, since the woman had been working to document the poaching of several protected species in the area for months, but her passion or naïveté kept every scene of carnage viscerally upsetting. This current example was especially hard on the young woman, since they were acting on a tip and hoped to reach the clearing while the tigers were still alive and drive off the poachers, or at least document their faces for the authorities. Sefton was somewhat relieved that they were late, since she suspected that if the fiery photog managed to confront the poachers, she would only get the pair of women murdered. Steph, though, was clearly furious.

"What is even the point!" Steph finally erupted.

Sefton reached across the table and tried to touch Steph's hand. "Steph..."

"No really?" Steph said, tears in her eyes, "Why am I even here doing this?"

Sefton hated seeing the photog like this. "So that you can document these travesties and share them with the world. If everyone knew what was happening then there might be real changes."

"Please... as if! None of my other photos have done anything but rouse those few people who already cared. And I'm just one of many journalists covering the poaching of endanger species! Everyone knows this is happening, they just don't care or maybe thinks it's a shame, but not worth doing anything about!" Steph looked down at the table. "Besides, it's all a lost cause anyway..."

This part was new to Sefton. "Why do you say that?"

"Because! So many species are already past the tipping point! Look at these photos: these six dead tigers are a measurable, meaningful percentage of the total tiger population on these islands and maybe in the world. Even if all of the poaching stopped, all of their habitat was perserved, there are unlikely enough tigers to restore the species with sufficient genetic diversity. And this is just one species! One example! There are so many species that are basically already extinct, we are just living with their ghosts!"

"That's a very grim assessment."

"Can you you even argue against it?"

"Well, what about zoos? What if you add in an optimized breeding program to the mix."

"Zoos? Please... they have even less genetic diversity and no where near enough animals to sustain that kind of breeding. They would need some kind of miracle breeding factory..." Steph got a thoughtful look that Sefton knew always spelled trouble. "Sefton.... have you ever heard of the Jizza Zoo?"

***

Steph tried not to look nervous as they waited to meet with one of the Jizza Zoo executives. If her plan was going to work this meeting had to go perfectly, even she knew it was a stretch.

In her mind Steph ran through her pitch again as  she looked in a mirror and touched up her makeup. She wanted to make a great first impression so she had borrowed a nice wool dress, expensive high heeled booties, and a smart blue jacket from a friend. She hoped that the tight sleeve of material managed to catch her modest figure and distil an air of alluring professionalism. Steph suspected she only managed to look like a librarian dressed for a date in clothes picked out by a hotter friend. She sighed, she knew relying on sex appeal was a poor strategy, especially for a mousey gal like her, but anything could help.

Sefton, Steph thought, had managed to capture sexy competence with her outfit. The tracker was a tall, broad shouldered woman who wore her dark hair in a no-nonsense hack job and whose dark, weather conditioned skin spoke of time spent in the wild. Her clothes, a rugged bush shirt worn under a handsome linen suit cut for a man managed to somehow enhance Sefton's androgynous, wiry frame and create a look that screamed strength and badassitude. Steph didn't think everyone would find her friend attractive, but those that did probably found her sexy as hell. Steph hoped the Zoo Executive was one of them.

She hoped that when the time came, that she would find her attractive.

The receptionist, a transformed Jizza resident, beckoned at them from her, or rather, his desk.  "I would have come over, but I'm not very mobile these days," warbled the receptionist through his flutes as he gestured to his planter with his vines. The receptionist was an odd combination of human and plant. He was planted in a large wash basin sized planter on thickly treaded wheels. Around the rim of this planter grew thick, flesh colored vine which Steph presumed the receptionist could slowly wheel themselves around with. From the planter grew a kind of stalk or pedestal of flesh, ringed in huge breasts with long thin vines for nipples. On the front of this pedestal was a large jug-like pocket rimmed along the top with a lip, about large enough to hold an adult person. On the back of the receptionist grew tall, thin reeds that acted as flutes and which the receptionist used to speak. At the tip of a long flexible stalk, the receptionist had the face of a beautiful, pouty lipped woman, framed by a mane of leaves studded with flowers, growing at the end of a long stalk. This was just a lure though, a beautiful trick face that could smile or frown or smolder to lure the unexpecting into the jug-pocket part of the receptionist. The unwary risked being trapped and constricted in the jug plant, having their clothing digested, and then fucked by the prehensile cocks which hid inside the jug. A sign on the door to the office warned guests to the risk. "The Director will see you now," tooted the receptionist and reached out another vine to open the office door.

Steph smiled a thank you despite how strange she found the creature. She knew she had to get used to it.

Steph and Sefton walked into the office of the Zoo Executive and were warmly greeted by a dignified middle aged gentleman. He had a handsome face with slightly greying hair and a very nice grey suit on. "Hello," he said warmly reaching out to shake hands. "I'm George Landiss."

"Hi," Steph said shaking his hand, "I'm Stephanie Potts and this is my associated Elizabeth Sefton."

"Hello," managed Sefton as she gave the man a firm handshake.

They all sat down and Landiss looked at the two women for a moment. "You look puzzled," he finally said to Steph.

Steph realized she had been making a face and blushed. "Sorry! You're ah, just more human than I was expecting..."

The man smiled easily and chuckled. "Well, while the zoo tends to favor hiring transformed Jizzans for customer facing positions, we have no qualms with hiring baseline people for more managerial roles. It helps keep a certain amount of continuance of direction. And after the last few directors decided to "join the zoo" they recruited me. So I took the job, moved here with my family, and my wife and daughter joined the zoo. They are now aquatic cock squid creatures." Landiss turned a framed picture on his desk toward Steph showing two creatures in a large fish tank: smiling, lipsticked feminine mouths strounded by tentacles with huge cocks for bodies. "I guess the Jizza effect doesn't really effect men in the same way so I'm still me and just really excited to help people transform."

"I'm sorry," said Steph.

"Oh don't be! They seen much happier now and I visit their tank all the time. Plus the hiring agency sent me a very pretty secretary to help with my heart ache. And well, she took a change too, she's still my receptionist. Mr. Jugs and I are still having a very fulfilling office affair." Landiss smiled. "But enough about that, I hear you ladies want to join the zoo!"

Sefton crossed her arms. "I won't live in a cage."

Steph quickly interrupted, she didn't want to hash out this argument again in what was a sales pitch. "I want to join the zoo."

"Welcome," he smiled and looked thoughtful, "I'm not sure why you are meeting with me though. We have a recruiting office that would be happy to start the process with you."

"Actually," Steph stammered, "we have an idea for something a little different..."

"Well, we don't as a rule take requests. But the recruiting office does try to align people's desires with their change... my family had a thing about wanting to be phallic and liking tentacles so: aquatic cock squid. Again, I'm not sure why are meeting."

Sefton sternly said, "then let the woman explain it to you."

Steph tried not to gasp, she couldn't believe Sefton was being so rude! And the she noticed that Landiss was quietly looking at her to speak. Sefton' sour gambit had worked.

Steph took a deep breath, "Mr. Landiss, zoos typically play a role in natural conservation. While they are also attractions, they typically invest a portion of their proceeds into educational efforts, animal rescue initiatives, and breeding programs. It's this humanitarianism that elevate what a zoo is. And I think it's time the Jizza Zoo joined the good fight."

Landiss nodded thoughtfully. "It's an interesting idea, but, ladies, we don't keep animals here. This is a zoo populated by human volunteers. I'm not sure why we would want to get into the conservation business..."

"Because what you have is a freak show," Sefton said. "People come and pay to see bizarre humans. Granted, having people come and visit Jizza probably helps normalize transformation, but the zoo itself is an attraction. Helping Steph assemble a breeding program here would legitimize this place in the eyes of the untransformed world."

Landiss paused. "So what exactly are you proposing?"

Steph's heart was hammering in her chest. She suspected that once she said these next words her life would irrevocably change from intrepid wilderness reporter to something else... something new. "Mr. Landiss, I'm proposing to become an animal breeding machine."

"And how would that work?"

Steph felt shakey and excited all at once. "I think it would work like this...."

***

Sefton tried to relax, which was proving to be difficult.

Sefton was naked, first of all, in public. Which she didn't really mind on principle: her tanned, lean body was something she was proud and confident of and she was never someone who embarrassed easily. It was more the crowd of spectators staring at her and Steph that was bothering her. Sefton hated people, hated the way they treated each other, and found crowds of them particularly distasteful. Being naked and vilnerable in front of them like this was very unpleasant.

And then there was the fact that Sefton was about to transform. She knew that the plan for her transformation was relatively mild and that if everything went right she would walk out of the enclosure pit a free woman... sort of. That even if her body changed she would still be free to travel the world and continue living her life as a tracker, just with a new and alien purpose. Sefton still found this entire enterprise strange and uncouth, but she believed in Steph's goal and, frankly, believed in Steph enough to undergo this strange treatment. It was just hard, especially after seeing the bizarre menagerie of the Jizza Zoo not to picture how horribly, bizarrely wrong this process could go.

Sefton was also terribly nervous for Steph. What she was proposing to do to herself was so much more life changing and extreme than Sefton's transformation. And Sefton knew that once she did this there wouldn't be any turning back, that she would be stuck in this new life of hers. Sefton hoped she enjoyed it. Sefton looked at Steph who smiled at her nervously as she stood their pale and naked and thin.

A technician, a cockwoman crossed with a tiger such that she had a tail, striped legs, and a barbed feline penis body, approached the two women with a small cart carrying vials. The tigercock woman growled instructions to Sefton and Steph who each took their specially prepared vials. Sefton made sure she had the right one.

Steph took Sefton by the hand and squeezed it. "Thank you for doing this with me. I-I hope you like it."

Sefton drew the shorter woman into a hug. "How could I not, when you offered me a chance to save a doomed species or twelve." She leaned down and kissed Steph hard on the lips. "Good luck!" And Sefton stepped back and drank her Alchemy.

Steph blushed and blinked stupidly for a moment before drinking her own elixir.

Sefton, who had a head start started to sweat and feel a twisting, wrenching in her guts. She groaned, which changed to a throaty moan as her vagina suddenly grew hot and wet and dripping. Sefton felt a pulling, squirming sensation and watched as her pussy slit grew longer and pushed towards a more rear facing orientation as her inner labia pulled inside her outer labia more. She wiggled her thighs and panted, feeling how larger and elastic her new, vaguely equine looking cunt was. She bit her lip as an aching pain pulsates through her hips and felt with her hands as they expanded outward, nearly doubling in width, further stretching her altered cunt. Her breasts warmed to the touch and grew from being quite small to generous c cups, an aesthetic choice by some Alchemist somewhere. Finally Sefton squealed in pleasure as the flesh of her flat, elongated pubic region pushed out and began to reformat itself into a brand new cock and balls. A frankly tiny cock and small, under developed balls that all looked half formed and unfinished. Sefton gasped and the tiny cock squirmed erect and ejaculated the smallest droplet of precum. And then her change was done.

Sefton stood and tried to get a feel for her new posture, her much wilder hips, her heavier breasts, and the tiny strange sensations coming from her small, undeveloped cock. It seemed that so far her change had gone according to plan.

A throaty moan from Steph got Sefton's attention. She looked to see the other woman, transformed laying on the ground fisting herself. Steph deceptively looked more normal than Sefton, appearing as a normal human woman with outrageous proportions. Steph now sported hips wider even than Sefton's, enormous, probably e cup breasts, and an oddly narrow waist. Steph also had an altered vagina, one identical to Sefton's new cunt, which was more rear oriented and wide and stretchy, which the woman was raptously shoving her arm up to her elbow into. She screamed as she orgasmed.

Sefton found the sight strangely arousing. She felt her new cunt grow hot and wet and felt a heat build in her flaccid, three inch cock which remained limp. She bit her lip, she had never been attracted to a woman before, but there was something about Steph or her smell which was making her heart race.

Steph, recovering from her orgasm, saw Sefton watching her and gave her a look of fierce, animal attraction and then laughed. "Phew! So far according to plan!"

***

Steph was alone in her new enclosure. It was a large pit style enclosure, dug about twenty feet below the level of the zoo walkways. The sides were sheer, vertical smooth concrete that she wouldn't be able to climb even if she wanted to. She was trapped in a cage of her own making.

It was an alright cage, as far as cages went, Steph thought. She had a covered hut in the centre of her habitat, filled with a mattress and blankets for the cold, although her altered body seemed resistant to low temperatures, which was nice. She had some plastic deck chairs to sit on and some shade trees and umbrellas scattered around the ground. There were some grass patches and medium sized wading pool she could cool off in or bath in. On the side of her enclosure nearest the door her zookeepers used to access her habitat was a picnic table where they would leave her meals and snacks, which today was a platter of fresh fruit. Steph also had a small library of books she was allowed to read and tablet with limited media functions that she could view after the zoo closed for the night. She sighed, for better or worse, the enclosure was her home now.

Steph stretched out in the deck chair she was using to bask in the sun with. She was naked, the only way she was allowed to be now, and enjoying the way her much enlarged breasts felt in the sunlight. Her new body, even this relatively normal phase one form, was so much more sensitive than her old one. She let her hand drift down to stroke her pussy, mmming at the feeling. She was always on such a short fuse these days and her new, huge cunt was always so eager to be touched. And since she had nothing else to do until Sefton came back she might as well take care of herself. She closed her eyes and slid a hand up to the wrist inside herself and used the fingers to rub her nose sized clit.

Steph heard a voice and glanced up to see a tour group gathered on the walkway above her enclosure watching her. Steph blushed and pulled her hands away from herself. Somehow she kept forgetting she was in public; no more than that, she was on display. She didn't want a bunch of strangers to watch her jilloff. She should wait until after the park closed...

Steph squirmed a little in her chair, the span of her wide, wide hips knocking the arm rests. Her pussy was still so hot and wet and ready. She bit her lip and blushed. She was on display, people were going to see all kinds of private moments: her using the bathroom, her being fucked, her giving birth... she moaned at the thought. What was a little masturbation? Besides, isn't this what the people came to see. She closed her eyes and let her hands drift back down to her snatch.

Besides she had time to kill until Sefton came back...

***

Sefton couldn't really believe she was about to do this.

She was several hours drive away from Jizza visiting a nearby zoo. It was a modest place, more of a game refuge than an actual zoo. But it did have exotic animals, imported creatures who largely earned their keep staring in commercials and other business ventures. But this sad little zoo was the closest to Jizza and it was open minded enough to let Sefton and Steph conduct their experiment.

Plus they had a male Zebra stallion.

Sefton had always liked Zebras.

Sefton puffed out her cheeks and blew a long breath. This was absolutely fucking crazy. She nodded to the scruffy zookeeper to open the Zebra's pen and in she walked. The Zebra stallion therein looked at her flaring his nostrils. She found she could smell him too, and found oddly that his smell was intoxicating. Sefton but her lip and felt a tingle in her guts that spread throughout her loins into a tightening, heat. The smell of the Zebra was making her wet! And not just wet, she felt a heat build up in her odd, half-formed little cock and balls. She panted, revelling in the Zebra's smell. She wanted him.

The Zebra apparently wanted her too, since he was pacing and smelling the air, his cock, his impressive enormous cock, was sliding out of its sheath. It was black and shiny and as long as her forearm and blunt like a horse's. Sefton felt her something in her pussy twist, which if everything was going according to plan, was her insides reforming to accommodate that beast. She hoped it was working, because she very badly wanted that monster inside of her.

Sefton and Zebra circled each other at first, both wary and shuddering with arousal. Their orbit tightened until Sefton could reach out and touch the equine creature, stroking its rough, striped back fur with her hand. The zebra snorted and stamped one of its hoooves. Sefton kept her hand on the beast, circled its body and then reached down under him and grasped his cock. Panting, she squeezed the enormous phalus, causing the snorting Zebra to tense. She drew her hand along the shaft and Zebra stood still. Sefton took her other hand off the Zebra and started to stroke her cunt, her other hand working the Zebra's cock and her face pressed into his side, breathing in his intoxicating scent. Sefton shuddered and almost came.

It was time.

Finally, she slid down under the Zebra, and crouched below him. She raised her wide pelvis and her gaping, reformed cunt and pressed it against the Zebras cock. The Zebra snorted and surged forward impaling Sefton who whimpered at the feeling of incredible penetration. It was amazing! She pushed back against the beast which began to thrust into her wildly, front hooves kicking the ground. Sefton groaned and panted and screached as she was pounded by the Zebra, until finally, the beast reared against her and came, filling her with his seed. Sefton screamed as her body was wracked by an enormous orgasm.

But that wasn't it all she was experiencing: the second phase of her transformation had begun. Her cock felt like it was erupting below her as her balls swelled and her penis became equine and larger. Her cock grew to match the Zebra's, forearm long, sheathed, mottled and black. Her balls swelled, growing to the size of apples, melons and finally enormous potatoe sacks which she was all but laying on top of. Sefton also felt a glorious pinch in her tailbone as a luxurious equine tail grew and cascaded down her legs.

The Zebra pulled himself out of her and staggered away satisfied and Sefton unsteadily climbed to her feet. Her balance was made awkward by her now huge balls, each easily a hundred pounds and filled with gallons of Zebra sperm. Sefton flicked her new tail and experimentally touched her Zebra cock. It seemed this part of the plan had worked.

Gingerly she waddled to the pen gate, she was anxious to go visit Steph.

***

Steph was running around her enclosure, tumbling and doing summersaults and whooping. She was trying to enjoy this body and her freedom of motion while she still could. If the plan worked she would probably never be able to run around like this again. Plus, playing like this helped kill the time of her captivity.

She wondered when Sefton would come back.

And then Steph smelled something in the air. Her heart began to beat faster, her enormous pussy grew wet and hot. And then door to her enclosure unlocked. In walked Sefton.

Steph moaned. Her eyes were instantly drawn to Sefton's altered package, her enormous balls which bulges out in front of her and hung down to her ankles. An absolute torrent of spunk waiting for her. Steph moaned again at the thought of all the semen flowing into her, changing her, making her pregnant.

Steph also stared at Sefton's cock. It was no longer just a small, unformed nub, but instead an enormous shaft of black and mottled flesh pushing out of a sheath. It bobbed heavily as Sefton waddled into the enclosure, its flat flared head pointed directly at her. Sefton's Zebra tail flicked and she stared intensely at Steph. Steph's heart was pounding, she wanted her friend so badly!

A small part of Steph realized that this was certainly her last chance to back out of this. That consummating her plan at this moment would commit her to a life in this cage, a life spent as a brood creature. Steph felt her cunt ache with arousal at the thought. She wanted this too much to back out. And even if she did want to renege, she could hardly do it now, after Sefton had already started down the path.

So Steph went to Sefton, crushed herself to her, and kissed her hungrily on the mouth. Sefton groaned in aroused greeting and pressed the enormous warmth of her balls and the hard fire of her cock against the other woman. "I need you," gasped Sefton, clutching Steph. "I need you too," Steph moaned back, "inside me right now."

Steph stumbled away and dropped to her hands and knees, raising her wide ass and baring her flared, dripping pussy for Sefton. Sefton, with a throaty growl lunged on top of Steph, her breasts laying on Steph's back and her enourmous balls resting on her legs. Sefton's huge cock ran along the cleft of Steph's cunt, rubbed along her belly, and poked between her heavy tits. Steph groaned, she needed that cock inside her, pumping her full of Zebra come. She reached back and helped Sefton inexpertly guide the cock inside her, steadily penetrating her. Steph cried out, as pliable and slick as her altered cunt was, Sefton's Zebra cock was stretching and filling her more than she ever had been before. Sefton grunted and began to thrust, into  Steph, at first steadily than increasingly wildly. Steph moaned and bucked back against Sefton, the two rutting wildly like animals, Steph screeching as she came and came and then exploded in an immense orgasm as Sefton screamed as she came and ejaculated furiously inside Steph with wave after wave of cum.

As Sefton pulled herself out of Steph, Steph felt her next stage of transformation beginning. Her insides grew hot and started to squirm as Seph started to stretch, her torso elongating, until it doubled in length. The lower part of her torso took on features and shape slowly resolving into a copy of her original with a second set of arms and pair of breasts. Steph panted, disturbed and aroused by the strange sensation, but knowing there were so many more changes to come. She moaned as she felt her lowest womb contract painfully, forcing the Zebra semen inside up into her lowest ovaries which began to tunnel through her body wall into her breasts. Steph could feel her womb now expand, swallowing up nearly all of the space in her new torso replacing most of her organs. Her breasts meanwhile expanded as Zerbra sperm and Steph's Zebrafied eggs met and became hundreds of thousands of Zebra embryos. Steph squealed again as the final change happened and her new torso grew a thin covering of striped Zebra fur and the hands of her new torso contracted into hooves. She lay there stretched out on the ground, longer by half and panting.

Steph lay there panting for a moment as what she had just done settled in. She had transformed. Her enormous lower breasts, easily k cups, were full of Zebra embryos which she would spend the rest of her life giving birth to. She knew that her new womb, hyper fertile as it was, was already implanted with a half dozen embryos, that she was already pregnant with multiple Zebras. Steph was a brood creature, a pregnancy machine in a zoo now until she died. This was her life now.

Steph awkwardly crawled her body so that she could see Sefton. Sefton, whose cock and balls had shrunk back down to their original, underdeveloped size, was swishing her Zebra tail and looking at Steph uncertainly. Steph smiled at her with all of the contentment she was feeling. "I think you should fill me with tigers next."

***

As Sefton returned to the zoo again nearly a year had passed since Steph and her had embarked on their bizarre conservation experiment. She was waddling through the tunnels to Steph's enclosure, contending with her enormous balls, swollen with the sperm of a Rhinoceros. She was already starting to feel her heart beat faster at the prospect of fucking her strange mate, impregnating Steph was the most sublime experience in her life. Her rhinoceros penis, one of the oddest cocks she has had on her body, was growing hard. It was enormous and long like one would expect, and droopy like a bulls cock, but it had a strange ridge of articulation and its tip looked like a smaller tube emerging from a wider one. Sefton thought it looked like she had piece of a flesh catheter sticking out of her cock. It wasn't her favorite animal cock. Sefton blushed, who would have thought she would have a preference in the type of animal cock on her body?

Sefton had been gone a couple months this time, had travelled to the great Savannah to find a wild bull rhino to fuck and collect sperm from. It had taken longer than she had expected to find a breedable male, but once she got close to one she easily seduced him. Sefton smiled fondly at the memory of being filled and fucked by such a powerful beast. She was strangely learning to love the beastiality part of her sex life.

And now here she was, back at the Jizza Zoo to deposit for seed in Steph and add Rhino breeding to her repertoire.

She finally reached the door to Steph's enclosure and a zookeeper unlocked it and let her in with a nod. Sefton ignored the man, already smelling her mates musk in the air. Her cock grew harder and her heart raced.

Sefton gasped a little when she saw Steph. She knew what her mate had become, but seeing it again always startled her. Stefton had collected sperm from six other animals before bringing Steph rhino sperm. This had left Steph with six additional breeding torsos, each with enormous ovary-breasts, pawed arms, and vaginas for birthing. Steph still had her original human torso, and then her Zebra striped torso, and then a tiger furred torso, an elephant, a gorilla, a cheetah and finally a panda torso before her original legs and pussy. Steph had clearly given birth to her first litters of Zebra and tiger cubs, but her other wombs were full and stretched so large that Steph was pinned to the ground were she lay.  She was beautiful and Sefton could hardly wait to add to her.

Steph must have smelled her since she twisted around, taking advantage of the relatively mobile first few torsos, to look at Sefton. She smiled, her eyes flashing with lust as they made eye contact. "Sefton," she said, "I'm so... happy... to see you. It's been so long."

"Too long," replied Sefton.

"You must have stories," Steph said, staring at Sefton's odd rhinoceros cock and swollen balls. "But I'm hoping that can wait."

"Of course," breathed Sefton, who was already waddling around Steph's chain like body towards her legs and primary pussy. She reached out and touched the enormous bulk of Steph's elephant womb, larger in size than Sefton, and slid her hand along its rough, grey hide. Her hand slid onto Steph's furry gorilla torso, whose gorilla hand ended arms were rubbing her enormous breasts and that torso's pussy, and then here spotted cheetah furred body segment, already round and straining around a huge litter of cheetah cubs, and then the black and white furred panda, just starting to show. Finally she reached Steph's legs and original pussy, which was already engorged and dripping with arousal. Steph had maneuvered her first few torsos so she could look back along her body at Sefton. Sefton looked at Steph's pussy and shuddered with need, her Rhino cock was fully extended and her huge balls were churning. But there was one thing she still had to do, made herself do. "Steph, are you sure you want this?"

Steph moaned. "Why do you always ask me this? Can't you smell how much I want it?" She gestured at her body, her seven body segments, some so large that she was unable to move. "It's not like I'm remotely normal at this point. Don't make me beg!"

"Steph..."

"Demons, Sefton! Mate with me already! Fill me with baby rhinos! I want it! Fuck me!"

Sefton smiled, grabbed Steph by her hips and pushed her rhinoceros penis inside her mate.

Up the chain of her body, Steph gasped happily.

***

Steph was laying in her new enclosure. It had been three years since she had decided to become half of an animal breeding program and it was beginning to set in that this was her life now.

Steph was simply enormous, she had sixteen additional breeding torsos sandwiched between her original top and bottom halfs. In order, her chain like body had her head and human upper body, a zebra section, a tiger section, and then an elephant, gorilla, cheetah, panda, rhino, leopard, lion, polar bear, second elephant, sea otter, orangutan, arctic fox, pangolin, and spider monkey sections. (The second elephant section was added because a single modified womb could only support two elephant fetuses at a time.) Steph's body all spread out was nearly 50 feet long and most of her segments were hugely swollen with offspring so that she weighed hundreds of pounds. Steph had decided she was really more breeeding machine than human at this point.

Steph's growing bulk had necessitated moving her to this larger enclosure. It was a new pit, shallower since there was no risk of Steph trying to escape, and had a simple concrete pad for a floor. This allowed the enclosure to be flooded so that Steph could float her enormous body and enjoy some limited amount of mobility during the day. She found that if they filled her cage just deep enough so that her largest womb of the moment just cleared the floor she could actually paddle around decently with her many limbs. The enclosure water was temperature controlled and the addition of shade or rain umbrellas meant that living in a wading pool was actually quite pleasant. Steph quite liked her new home.

Steph was laying on the plastic boogie board her zookeepers gave her to keep her head comfortably above water and was basking in the sun.  It was a nice day and the zoo wasn't too busy, which was exactly how Steph liked it so she could just float and doze the afternoon away. Steph, to her own surprise, has found captivity and immobility pleasant. She suspects this has to do with her body, that with the multiple pregnancies she didn't have enough extra energy to get bored and that her particular cocktail of hormones keeps her feeling docile and blissed out. Steph sighed happily, she was actually enjoying spending her life floating in a pool feeling the joy of new life growing and moving inside her punctuated by the orgasmic splendor of birth after birth after birth. It was magical and actually making the world a better place.

Really, Steph's only complaint was that she was always horny. It depended on where each one of her segments was in their gestational cycle, with each of her pussies being ravenous during estrous, hungry during the first trimester, dissinterested mid pregnancy, swollen and extremely sensitive and horny again at the end. Since each womb was running on its own clock, Steph usually had some part of herself that was dripping with need. So Steph would spend the day idly masturbating, almost reflexively jilling off with whatever pussy-safe limbs could reach. (She learned early on that hooves did not work.) This took the edge off, but did nothing to assuage Steph's main problem: that her main pussy was always in heat.

Steph's main pussy, located between her human legs at the end of her body was always throbbingly horny. Everyday she could feel it, a dull ache begging to be filled. Steph could, if she spent her whole day on it, maneuver herself so that she could finger or eat out her own pussy, but she found that didn't really fix anything. Some of her zookeepers were happy to fuck her, and some of them even had large and animalistic enough cocks to scratch Steph's itch. But the only thing that really satisfied her, that gave her the shattering orgasms that have become the centre of her existence, is being fucked by her mate, Sefton.

Steph sighed again, wistfully, Sefton had been gone a long time. She wondered when she would be back and what new animal she would bring with her.

Steph groaned as she felt her largest swollen stomachs ground themselves on the botto of her enclosure. She knew that meant they were draining her pool. Steph was annoyed, it was still the hottest part of the day and her cage wasn't due to be emptied until nightfall. This probably meant the zookeepers needed something from her. As Steph came to rest, heavy and immobile, on the hard floor of her enclosure she sighed in annoyance. She was having such a nice day.

Steph heard the door to her cage unlock, but because her first few segments were pregnant and enormous she couldn't twist to see.

"Hello beautiful," purred a husky voice accompanied by an intoxicating scent. "I have a present for you."

"Sefton!?" Squealed Steph, body already responding to the proximity of her mate.

Sefton waddled around Steph's enormous bulk and into her view. Her balls were swollen and hid her legs and her cock had grown into a wickedly barbed, feline cock that had already emerged from her sheath. Steph looked at the crop of tails Sefton had grown, one from every tailed species she had "sampled". Steph bit her lip in excitement when she saw the new one, a beautiful snow leopard tail. She had always thought snow leopards were cute. "I'm so glad you're back!"

Sefton waddled out of view again, on the hunt for Steph's legs and vagina. "Are you sure you want this?" She purred.

"Yes! Of course!" Steph whimpered, "mate with me!"

The tour guide, a Jizza native who described himself as a "SWB Zebra" led the group along the path. His transformation gave him the round, muscular hind legs and penis of a Zebra and then collapsed his torso so that his mohawked, feminine but vaguely equine face grew straight from his hips. He swished his tail and clipped next to a sign saying "Jizza Zoo Breeding Program."

"Alright folks!" The guide said brightly stamping his hooves for attention, "this is the Jizza Zoo Breeding Program where a zoo transformee gives birth to endangered mammal species to send to other zoo breeding programs or to rehabilitate for the wild." The guide nodded towards the enclosure. "There you can see Steph, the brood creature in the program. Since joining the zoo five years ago Steph has given birth to hundreds of endangered animals. She currently has 32 "segments", extra breeding torsos, which allows her to become pregnant with 24 different species. She has a few repeats! You can tell which species she is breeding by what her segenebts look like: every segement gains some characteristic of the breeding species." The guide paused to allow the tour group  to puzzle through Steph's body. "Each segment is basically continuously pregnant from internal stores of fertilized ova. Every fertilized ova then undergoes recombination to increase genetic diversity and splits into multiple fetuses per litter for maximal efficiency. Steph's wombs can stretch so much that she can carry two elephants to term or a dozen tiger cubs or six of my favorite animal." The guide paused again until a member of the tour asked him what his favorite was. The guide yipped with laughter, "why, a Zebra of course!"

"Steph here only represents half of the program. Her mate, Sefton, is an experienced wild life tracker and guide who travels the world finding rare animals and colleting their sperm. She does this by being fucked by the animals until they ejaculate inside her and then her body stores and amplifies the sperm. Sefton then returns to Steph, fucks her with her penis, and deposits the sperm she is carrying in her mate. This transforms Steph and adds a new breeding segment. And you folks are in luck! Apparently Sefton has just returned from safari!"

The tour group watched as the door to he enclosure opened and in waddled Sefton, heaving huge balls, and studded with dozens of animal tails. She marched straight to Steph's face and kissed her before waddling along her body to her human legs. The tour grew silent as Sefton fucked Steph leaving both halves of the breeding program panting and crying out in orgasm. The crowd then watched as Steph's body elongated growing additional huge breasts, new limbs capped with three long, curved claws instead of fingers, and a shaggy pelt of grey fur. "It looks," the guide finally said, "as if Steph will be having some baby sloths in the future."

"Anyway," continued the guide, stomping his hooves to regain attention, "the Jizza Zoo Breeding Program has been such a success that we are looking to expand it with a bird and reptile breeding pair. We have also gotten interest from conventional zoos looking to emulate us." The guide paused and swished his tail. "We are looking for volunteers interested in becoming brood creatures to be paired with an experienced conservationalist gatherer. Anyone interested should speak to the recruiting agent we'll meet at the end of the tour."

"Now if you'll follow along this way..."

The End
