In the Name of Science
In the Name of Science Written by Leo_Todrius Commissioned by Tiger-shifter
Another peaceful morning swept across the Pharmatech cheetah conservancy, the sun barely creeping over the trees. The conservancy sat on an elevated portion of land in the bend of a wide, flat creek, a steady rush of water providing the encampment with relaxing white noise. Thick bushes and shrubs swayed in the breeze, the leaves of the trees adding to the noise... it was a particularly beautiful spot in northern Zambia, less than a mile from the Congo border. Completely isolated, completely independent from the local government... it was an oasis of sorts, and for Tyler it had become a sort of home.
Tyler moved out of the dormitory wing of the conservancy, moving down the two cement steps into the paddocks. He reached up, brushing some of his dark blond hair out of his sleepy eyes, watching the sunlight creep through the fences, casting spots of light across the floor. The paddocks were home to the conservancy's ten cheetahs. Tall chain link fences segmented out twelve large cages along the outside, a walkway around the inside edge of all the cages, and a much larger cage in the center used for treating wounded cheetahs, allowing them to breed, or any other interaction activity. Each cage had a small pool of water, fresh hay, a food slot on an artificial tree for declawing on, along with other amenities.
Tyler's blue eyes surveyed the state of affairs in the cages. In most cases the cheetahs were lounging, gnawing on some breakfast. A few were asleep, taking cat naps. All in all it seemed normal... but just a bit sad. While many conservancies were focused on treating animals injured by poachers and returning them to the world, the black market for cheetahs was too high... Until there was a way to stop the poachers, it was likely the cheetahs at the Pharmatech facility were going to be there a long time... But they would be alive and would perpetuate the species, and that didn't even include Pharmatech's primary area of research. Tyler reached the other side of the paddocks loop and signed off that everything seemed normal before he walked up the two steps and entered the sciences wing. His reflection caught on a wide pane of glass. Tyler was twenty years old, an undergraduate student taking a year abroad as an intern for Pharmatech. He was tall and lanky, a bit of muscle in his upper arms and shoulders and not much else. His face was smooth, his body nondescript. What stood out most was his aptitude for helping animals.
Tyler turned, looking past his reflection and into the window that separated the largest cage in the encampment from the facility itself. The cage had been granted to their most prized animal... the world's first genetically augmented cheetah, Rutuba. Despite the green movements protesting genetic manipulation, bringing animals back from the brink of extinction was requiring more and more aggressive steps. Rutuba was the first successful attempt. His genes had been skewed rather slightly, promoting traits that would lead to successful breeding. Fertility, sperm count, heat cycles, smell, taste... anything that could help him mate had been boosted. While the conservancy acted as a conventional stop gat when it came to keeping the species alive, Pharmatech was most interested in the modification and engineering of subjects to ensure survival, propagation, and growth. Rutuba was their star test subject.
The intern smiled at the cheetah inside, draped over a long limb. He had such grace... Ty had seen the cheetah work himself into positions he had never seen any other cheetah get into, almost as if he was sitting up at times... Still, Tyler had work to do. He moved down the hallway to where a desk had been set up in an out of way corner. It wasn't prestigious, it wasn't idyllic, but it was for a good cause. Tyler was just glad Zambia's primary language was English. At least the locals that worked in the conservancy spoke the same language. Tyler sat down and pulled out his forms, checking to see where he left off before filling out more requisitions.

The day had slipped by, the afternoon had come and gone and evening had settled in. The sun dipped below the trees, casting long shadows around the outside of the complex and filling the heavens with shimmering orange and gold. Days started early and ended early, at least for most. Tyler was a different breed.... He considered it dedicated, but his co-workers had other words. While they were off sharing drinks and unwinding, Ty was putting in a third hour past the end of his shift. He had done paperwork, inventory, feedings... he'd done everything he was supposed to and more. Even inside, he could hear the purrs and chuffs of the cheetahs bedding down after their dinner, digesting the meet.
Tyler's stomach growled in dismay that in all his time of feeding that he had not fed himself. He stood up and stretched, moving along the hall, but not toward the cafeteria... He just needed a good stiff coffee to get him through the project progress report. As supportive as Pharmatech was, they were starting to get concerned that the program hadn't turned over enough progress. Rutuba had not sired any mates, they had not deemed if it would even be safe. Tyler hated asking for more time in the form of a formal report. It seemed so indirect, so roundabout. He was sure the would miss the point and take it as an excuse rather than a request, but... it was the way things were done.
Tyler sighed as he came up to the coffee machine at the end of the hall, sliding his cup under the dispenser. He reached up and pressed the button, listening to the steady steam of brown pouring into the cup. The scent was a bit bitter, the coffee overheated after a long day. He had waited to long and all the freshness was gone... but thankfully the caffeine would be unaffected. Ty watched a bit anxiously as he watched the brown swirling higher and higher toward his arbitrary stopping point... at least that was what he was looking at before he felt the sting on his neck. His hand fell away from the button, reaching to the pain on his neck. He had expected the bite of some terrible African insect, but what he found was something firm, feathery.
"What in the world?" Ty whispered, pulling it out of his skin, bringing it around to get a better look. What he held in his hand was a dart, a small and feathered tranquilizer dart. Ty looked at it in disbelief, his extremities starting to go numb. He felt weak at the knees, the elbows, the head. Slowly Ty turned, trying to figure out what had happened. As his eyes grew fuzzy, he was only able to make out a large figure in the driveway, the evening sunset surrounding him in bright light. Ty couldn't make out any details other than his sleek, muscled body... and what had to be his hair worked up into triangular points on the top of his head... but it wasn't hair, it was something else... Ty's head tilted as he fell against the wall. "Ears?" he whispered before passing out cold, slumping to the floor in a heap.
***
Consciousness struggled to swim back into Tyler's mind and body, his fingers flinching, moving in minute jerks. He flexed a bit before groaning, feeling as if his limbs had been filled with cement, weighed down by the tranquilizer... but his arms were raised... why were they raised? Not by him... And the air was cool on his chest, his shirt was gone... Ty opened one eye and then another, trying to gain a bearing on where they were. There was soft grass.... Moisture, some of it was wet. Ty blinked again, getting some of the fuzz out of his eyes. Yes, moisture, a pond.... And a tree, and another tree.... And chain link fencing, reinforced fencing. He was still in the complex, but he was... in the testing chamber for Rutuba... the experimental paddock given to their great experiment.
The surge of adrenaline rushing through his body fought off the tranquilizer, the scientist coming more to his senses. He looked around and then up, seeing the leather and metal cuffs holding his wrists, a long chain attached to a pulley in the ceiling, running off to a gear system somewhere else. Ty looked around frantically, trying to see where Rutuba was... but there was no sign. He glanced down, realizing that he was still wearing his pants, though his shoes and socks had been taken just like his shirt. Ty murmured softly.
"This isn't funny guys, I understand that I work too hard, but... let me out, I'll relax I'll take it easy." Ty whispered. There was no response. He gave a forced chuckle, "Ha ha, very funny, you got me..." Ty whispered. There was still no response. Well, Ty didn't plan on giving them the satisfaction. He closed his eyes, taking deep breaths, focusing on figuring out a strategy to free himself. Despite his best efforts to think, the tranq didn't make it any easier... and if anything, the rustling in the tree leaves wasn't helping.
Tyler's eyes slipped open in terror as his head inclined. He saw the large paws come through the leaves first, landing on a thick branch. The claws spread apart and then slid back before the yellow and black spotted fur extended in the form of powerful arms, then leg, the sleek and agile feline body emerging. Two long stripes of black framed the fang filled mouth, the moist nose inhaling the scent. The large cheetah bounded down from limb to limb, no doubt coming to investigate. Tyler knew that most cheetahs wouldn't take kindly to humans invading their territory and Rutuba had been enhanced to be even more of a cheetah. Still, he was a human; he had one pathetic defense... a defense that he could pull off more easily in his current state than anything else.
The wet heat started spreading out across Ty's groin as he voided his bladder. The golden liquid spread like a massive stain across his jeans before it ran down his legs, soaking into the hay. It was his human scent, his marker, a way of telling the cheetah who he was, hopefully the fact that it was only on himself and no where else wouldn't confuse the cheetah into thinking that it had a competitor for the territory. Ty was suddenly regretting his actions. What if the urine provoked an attack? He'd be found dead, covered in his own pee. Ty groaned in despair... only to be met with a most surprising sound, laughter.
At first Ty though it was coming from some hidden pranksters, but it had come from the tree. Ty turned his head, confused... but no more than he was about to be. The cheetah stopped his descent along the branches and moved, stepping off not with his front paws, but his back. Tyler watched as the cheetah's back paws rested, muscle shifting to support the legs... and the legs straightened upwards. The cheetah's back lifted up, his head shifted down and forward as he flexed his arms, not as a cheetah would, but as a man would.
Ty gasped softly, realizing that the large feline's anatomy was practically human... Knees, elbows, ribs, neck muscles, ankles... The cheetah was standing on his two feet, his arms at his side, golden eyes gazing at the restrained human. Ty was stuck in place, his jaw hanging open in pure shock. Rutuba advanced, coming to a stop just in front of Ty. He reached out, running his clawed fingers through Ty's hair. Ty shuddered, gasping in confusion. The cheetah leaned down, sniffing at the human before he held his mouth agape, making the chortling noise cheetahs made at certain smells.
"Now that won't do... that's a silly human scent. You need something... far better." Rutuba said, one clawed paw moving to his fuzzy sheath. The hand groped and rubbed at the furry pouch before the tip started parting, the rough, faintly pointed head of his cheetah cock started slipping out. The thick length was half hard, but it seemed that Rutuba had something in mind. Despite the exposure of the cheetah's cock, Ty was stuck a step before.
"You can talk? This... this is astounding! We had no idea, we were so... Is this recent? Oh m god, you can talk... and stand. This is..." Ty paused, looking up at the cheetah, "Scent?" Ty asked, finally catching what Rutuba had said.
"This isn't recent... I've been waiting for so long, but you humans work too slowly. You made me the perfect mate and then gave me no one to mate with. It's time I take a hold of my own fate." Rutuba said.
"I'm not a girl; don't you want me to get you one of the female cheetahs?" Ty asked. Rutuba said nothing, sliding his hand up and down his feline shaft. Ty hesitated, "Female scientists?" he whispered. He wouldn't have actually done it, but he was curious. Rutuba smirked.
"I have just what I want." He whispered before he sighed, releasing a muscle of his own. Ty was confused for a split second until he saw the cheetah's urethra spread wider and the cock pulse before the acrid scent of piss launched out. Ty tried to look away, but all that succeeded in doing was let the urine splatter across his cheek, running down his neck and soaking his shirt. Rutuba moved his shaft, dousing Ty's hair, soaking the blond before he moved, showering Ty's chest and stomach, his legs, even his lap. Ty gasped in shock, feeling how much hotter the cheetah's piss was as it showered his lap, soaking into his bush and cascading over his balls. Aside from the heat and the scent of piss, there was even a bit of an ammonia smell, the scent clinging to Ty's smell, marking him.
Ty tried to fight it, tried to look away, but as the urine cascaded down his face, some cured over his lips, a few drops getting in. The acrid, almost alkaline flavor burst in his mouth, blooming across his tongue. Despite the sensation, Ty tried to keep his mouth shut... but the hot urine was saturating his entire body with warmth unlike anything he had ever known before, sinking down into his bones, making him feel as if he was radiating it. His body responded to the heat with a nearly crippling growl from his stomach, his neglected appetite torturing him now. As the golden showed trickled to an end, Ty doubled over, panting hard. He writhed and grunted, moaning, his stomach almost cramping.
"So... hungry, I can't... I need... Ugh..." Ty panted. Rutuba chuckled softly.
"I don't have much to offer human... except the food you've given me. The meat, the feed..." Rutuba whispered. Ty's mind was boiling with cravings.
"Anything, anything, so hungry. I need it. Rutuba turned, crossing his paddock. His feline hips swayed, his black and blond tail swaying from side to side behind him. He moved, lifting the metal cover from a table. Spread out beneath the cover was a buffet of cheetah food. Raw meats, special grain feed full of minerals and vitamins and chemical elixirs and meat flavoring to get them to eat it. It was animal food, but it was food... Protein, fat, grain, carbs, sugars, juices... Ty grunted softly, craving so much. Rutuba walked from the table across the paddock, moving over to the gear box. He reached inside through the hole he had made and released it, pulling out several feet of slack before he slid the lock into place.
Ty's arms fell down in front of him, still bound together, but the slack was there. Ty slammed his back into the wall, pushing up with his legs until he was on his feet and steady. With the slack on the chain, he all but ran for the table, crossing the expanse in no time. He reached up, bound hands trying to grab fistfuls of the feed from the huge vat, but he couldn't coordinate with them locked wrist to wrist. He tried tearing the meat with his fingers, but that was equally futile. Giving up on his manners, Tyler took a deep breath and then leaned forward, his face dunking into the container of brown slime. His lips parted and he let the slip slide into his mouth before he closed it, chewing down, gulping at the grain, swallowing greedily.
Rutuba moved over, reaching up to run his clawed fingers through Tyler's hair, caressing his skull as the human ate and ate. Tyler was famished, starving, insatiable. He kept working at the vat, gulping the potent food down. He pushed his face around, the slime smearing across his cheeks and caking his teeth. Minutes passed, and still he ate, taking in several day's worth of the feed. His stomach was stretching, filling, but still he consumed. Rutuba purred, watching the human store up on the nutrition he would need very soon. His body gurgled, trying to make room for all the food he was taking in. His systems started to metabolize faster than ever before, struggling to keep up... but the food was so rich, even metabolizing it... his body wasn't going to be able to utilize it all.
With each gulp, each swallow, Tyler's body was starting to swell. The weight first started pooling along his stomach, his defined abs disappearing beneath a layer of fat before the skin stretched, pushing out, rounding into a small belly. The muscles of his arms disappeared as well as they were ringed with fat. His belly went from the size of a bag of sugar to the size of a cantaloupe before his pectorals started to stretch as well. Years of health were destroyed as Ty's fit body was becoming chubby.
Seeing the human bloat was turning Rutuba on more than he had even anticipated. That extra meat and girth, it was enticing. Rutuba let out a slow growl, his cock achingly hard. He wrapped one paw around it and moved to the other side of the table, staying out of Tyler's way. The anthro cheetah started to pump his shaft, his hand sliding up and down the black length, squeezing and caressing, imagining all the things he was doing to the human, watching as Tyler's cheeks grew softer. It was all too much for Rutuba and he let out a call before his cock pulsed, sending jet after jet of tainted cheetah cum out, the stuff splattering across what feed remained like a white oil slick.
Tyler hadn't noticed the cum, he had been too focused on his food. He was eating everything up like a black hole, but when his lips clamped down over a portion covered in cum, the salty musky flavor invaded his mouth. For the first time since he started, Tyler paused. That was the exact flavor the meal had needed. His eyes slipped open, shimmering a bit. The blue faded away, looking almost silver for a moment before a faint, glossy gold color began spilling in. He looked at the food, realizing the flavor had come from the white stuff on the food. With a renewed lust for food, Tyler began seeking out all of the food drenched in cum, swallowing with gusto... and changing even faster.
The forming fat on his body began pooling unevenly into his pectorals, the flesh ballooning out and stretching, rounding, inflating... the two mounds filled quickly, pressing together with their rapidly swelling size, a crease of cleavage between them. His nipples swelled and thickened, darkening... in moments his chest looked as though it belonged on an overweight woman, not a man... The thicker nipples glistened with the sheen of a building moisture. At first it was clear, like sweat, but then a thicker white moisture began building at the plump nips before the thick substance rolled down, replaced a moment later by another drop, then another... he was lactating...
It had taken over a half hour, but at last Tyler was finishing off the vat of brown slime. He ran his tongue around the edge at the bottom, getting every trace of slop and slime and cum that he could... but as he rose up, Rutuba took in his new features, his changed face. Even as the cheetah watched, Tyler's face warped. The skin on the tip of his nose had darkened, at first taking on the brown of the food before darkening even more to black. The bottom of the nose turned up a bit, the nostrils visible forward as the point of the nose melted back a bit, barely sticking out from the face. Likewise, Tyler's lips had darkened to a surprising jet black in color, guarding his now jagged teeth.
Tyler's once proud crystal blue eyes continued to change, the gold picking up even more vibrancy and color, but they weren't the only thing drawing attention. They stood out even more as his eyelids turned black, ringing the gold orbs as if to highlight their presence. His blond hair seemed a bit more wiry, portions of the blond darkening to a rich brown, almost black... almost like spots. Stubble had pushed out along his face, blond on his cheeks, but devoid of any color on his chin, a crisp white. Even his ears had not escaped alteration, rising up into slight points... but Tyler didn't notice a thing. He licked his black lips with his long tongue, his hunger unphased. He had finished the nutritious paste, but that was but one course of his meal. His eyes settled on the hunks of meat and he lunged.
Like a proud parent, Rutuba watched Tyler tear into the meat with the sharp teeth at the side of his mouth, ripping out hunks, gnawing the food into shreds. The blood of the meat washed some of the paste away, revealing even more soft stubble beneath. The soft stubble started to spread out, sliding down his neck every time it contorted with the consumed meat. While his throat stubble remained white, the hairs creeping down his neck were the same rich blond from his cheeks and head, save for the small speckles of black that seemed to start with a single hair before spreading out into small spots.
Progress on the meat was slower given how thick and tough the meat was. Another half hour had passed and he had barely eaten half of the huge chunk of meat, but every ounce Tyler had consumed was showing on his body. His chin had bloated out into double, his breasts were huge, and his belly was rotund... but as he ate, there was a different sort of shifting in his body... that of blood. His blood pooled into his shaft, coaxing it to a renewed and exaggerated erection. It pushed his piss soaked pants to the limit, tenting them something fierce. His balls tingled, but there was even a growing heat behind his balls, sinking deep into his pelvis... and Rutuba knew precisely why.
Sensing his creation coming of age, Rutuba only wanted to help the process along. Once more he stroked and fondled his shaft, imagining what Tyler was becoming, what he would look like when he was done and what they could manage together, side by side. His dreams were intense, too intense to hold back. Once more the thick sperm arched out, landing on the meat, seasoning it. Tyler shuddered as he got a bite of salty, musky beat and he started chowing down even faster, gulping it, licking it. The blond fur moved along his body even faster, this time creeping up past his facial hair line to cover more of his face. The stubble grew soft like fur, spreading up past his cheeks to spill across the bridge of his nose as it flattened, becoming a steady, smooth line all the way from his brow to his nostrils. The fur swept up around his eyes and across his forehead, pushing back into his hairline. A moment later the fuzz moved up the back of his pointed ears, then down the front.
As Tyler gulped and chewed and tugged on the meat with his mouth, his face was undergoing the zenith of its alterations. His upper lip, covered with golden fur, was quivering and contorting. Tyler got a rather vicious bite of the meat and tugged, but for a moment it felt as if his upper lip had torn... but the split in the upper lip was natural as it rose up to the base of his nose, the two curved bits of lip swelling out a little. It was then that his entire face started to ache and shift. Tyler let out a yowl of pain, but decided the best treatment to his pain was comfort food and he resumed eating. Rutuba watched as the former human's jaw popped and stretched, extending forward. His feline nose angled up as the skull beneath the upper lip stretched out as well. After a few moments of rather intense pain and sensation, the skull stopped growing, leaving Tyler with a pronounced muzzle.
To celebrate an end to the pain, Tyler tore off a huge strip of raw meat and gulped it down, his ears quirking a little forward and back before his hair rustled. For a moment Tyler went deaf, panic ripping through him, but seconds later the hearing returned as the ears emerged from the top of his hairline, the ears sticking out along the top of his head. Tyler paused in his eating once more, feeling like a completely different kind of man... no, cheetah... at least his head was all cheetah. The rest of his body was still undergoing a rapid change.
The hair on his legs and arms grew in thicker than ever before, becoming soft as soon as the skin disappeared beneath the thick coating... and like some wonderful disease, black spots were appearing all over, marking the golden coat evenly and beautifully... but that was nothing compared to the soft downy golden fuzz that was spreading out from where the center of his chest had been. The cheetah fur rushed out, covering his thick, round, luscious breasts up to the nipples before stopping, spots appearing in the fur so it blended in with the rest. Tyler's nipples still oozed thick white cream, the drops running down the underside of his breasts, but more wet spots were forming along his stomach, saturating the fur.
As Tyler continued to gulp down the food, his stomach started to rumble... not with hunger or with indigestion, but the flesh itself was shifting. In the midst of the fur, four more spots were becoming hairless, the skin darkening. The four circles of furless skin emerged, the centers seeming almost darker before they swelled out into tiny nubs of flesh. The nubs contorted before they matured into fully functioning teats. The clear fluid appeared from each of them before thickening into the opaque white cream, dripping steadily. The belly beneath the teats shifted, molding into four separate mounds of flesh beneath his two full breasts and his now, slightly diminished, belly. All six breasts swayed under their own girth, each dripping a steady flow of milk.
Sensing that his creation had changed enough, Rutuba produced the key to the restraints and approached Tyler. Tyler growled a little when he considered Rutuba a threat to his food, but son relaxed when Rutuba showed no interest. The anthro cheetah moved, unlocking the restraints from the human's wrists. As the cuffs fell to the floor, Tyler's hands almost looked comical. The fur came to an abrupt stop at the wrist and left his human hands, almost as if he was wearing flesh gloves... fat flesh gloves, even his fingers and palms hadn't escaped the expanding bulk of their owner. After a moment Tyler realized his hands were free for the first time... an exquisite tool to aid him in his eating fest.
Rutuba watched as Tyler reached up, using his hands to tear at the flesh. He held the meat in place as he tore into it, though his fingers were starting to flex and contort involuntarily. Saliva dripped from Tyler's mouth, landing on his hands. His fingernails were getting stained from the blood and juices, turning from white to red, red to brown, and then to black. The fingernails surged out, stretching into black points before the flesh seemed to grow soft. The nails sank into the fingers, extending from the tips as claws before the flesh hardened again to contain them. Tyler used the claws at once to tear into the meat like never before, getting off larger and larger hunks, feeding them to himself as parts of his palms swelled up like tiny meat filled balloons, forming paw pads. The blond hair surged across his hands, filling in every part around the paw pads, covering his fingers and the back of his hands completely. At last, he had the paws of a true cheetah.
A fresh gust of cool evening air drifted through the windows of the room, filtering into the caged area. Rutuba stopped, his eyes closing as he took in a deep breath, basking in the bit of nature. Despite how amazing Tyler looked, he turned to gaze out at the night sky. Indeed, it was night. The hours had slipped by and Tyler was still eating. The humans were asleep, the jungle had given into its nocturnal form... but the cheetahs had all the time in the world. Rutuba looked back at Tyler, appreciating his form. He had the head of a cheetah, the six breasts, the furry arms and legs, hand paws... but there was still more to change... and more for him to consume.
"You must be thirsty Tyler, come drink." Rutuba commanded. Tyler's teeth shredded some meat before he pulled up, a strip of flesh hanging out of his feline mouth. He was curious what Rutuba had meant, but then he saw the large bowl of ilk on the floor. Tyler's gold eyes sparkled as he bounded over, landing on all fours, leaning down to lap up at the milk. A wide, flat, sand-papery tongue dipped onto the milk, curling just enough to bring it up into his muzzle. The milk was cool, refreshing, and calming after such an exquisite meal. He swallowed it down, letting it fill in all the crevices between the meat as it was digested.
Just as the other food had seemed to nourish Tyler, the milk was doing its part as well. His coat was becoming softer, shinier, the spots more defined... but it was also helping his body to mature in other ways. The droplets of milk leaking from his nipples were coming out faster and faster, becoming a steady drizzle that dropped to the floor, soaking into the hay. Rutuba licked his maw, his whiskers quivering as he forced himself to hold off, to hold back. Tyler kept drinking the milk, though his belly was hanging lower to the ground, his legs and arms seeming to bulk up with fat and muscle just to keep him up as he drank.
Tyler's cheeks tingled before long, thin whiskers of his own were pushing out of the skin, but the true focus of the transformation was currently centered around his waist. His pants had been stretched to their limit by his expanding ass and growing hips. Even his legs had thickened up enough to stretch the seams. The cheetah fur had fully covered Tyler's stomach and back but as it advanced down under the waist of his pants and swept across the curve of his ass, it was too much for the pants and underwear to contain. The sound of tearing and popping came as cloth separated and seams burst. The pants and undergarments nearly exploded, falling to the ground in tatters as Tyler's furry ass cheeks began spreading apart.
It would have seemed odd to many at first that his cheeks were parting, but the reason why became apparent as his tailbone stretched. Tyler's simple spine had become something far more complex, supporting movements on all fours as well as upright, but it was also stretching longer and longer behind him, his tailbone pushing out into an actual tail. At first it was a wriggling tube of flesh, but a soft amber stubble spread across the skin before it erupted into a short coat of fur, covering the tail up as it gained the muscles necessary to sway from side to side. The fur coated his ass cheeks well, sinking all the way into his dark black pucker.
Rutuba moved around Tyler, reaching to stroke the growing tail, caressing it, feeling its length and weight. It seemed so light, but only because all of the muscles were working in perfect concert. Rutuba moved his hand, caressing the round ass cheek, watching the fur creep down the back of Tyler's legs, but his interest was on a much different area. As Rutuba watched with a palpable eagerness, the fur crept over the boys hips, covering them completely and matching up to the spreading hair on the back of his legs. The fur shimmered in the dull refracted moonlight as it met up with the fur that already ringed his shaft, filling all the gaps in.
Tyler's balls seemed even larger as the sack was covered in fur, but his human shaft almost seemed pathetic in comparison to his massive feline body. As if sensing the shame, his shaft started swelling again, growing longer and thicker. Each heart beat pushed tainted blood into the length, Tyler's malehood stretching past the length any girth he had ever had before. The mushroom shaped head of his cock started to stretch just a bit, the smooth flesh getting a bit rougher. It certainly seemed a compromise to the painful barbs of the full cheetah.
Despite trying to drink the milk, Tyler's body was working against him. His hips were swaying, starting to thrust instinctively, but... that wasn't all. He was also gyrating his hips to get used to a new warmth, a new sensation. It ranged from a tingling to a warmth to almost a shifting inside of his pelvis. The heat that had sunk into him during the start of his meal had only grown stronger. It was most disconcerting, feeling as if the tingling was spreading, almost ready to burst. When Tyler though he could take no more, the building pressure came to a head.
A sudden rush of musky fluid ran down Tyler's legs, having leaked from a new orifice opening up behind his balls. With the gap open, Tyler suddenly felt as if he had a great void in his body, one that begged to be filled. His pleasure addled mind was unable to comprehend for the longest moment before he paused, his golden eyes looking into the night in confusion. He removed his head from the bowl and leaned it down, gazing between his fuzzy arms and legs, past his breasts and belly. He saw his cock and balls, but it almost felt as if... he had a pussy. Tyler was confused, though not by the dozens of physical changes that should have baffled him. He hadn't even questioned his plethora of milk drizzling breasts.
"What's... going on?" Tyler asked, though his voice was far smoother than before, almost silky. Rutuba grinned, a purr escaping his lips. He moved over and pet Tyler's head.
"You're almost there; you've almost been reborn... There's so little human left. You are such an amazing creature." Rutuba whispered, "All that is left is the last of your milk." he said. When Tyler leaned back toward the bowl, Rutuba shook his head, "No, this milk." he whispered, bringing his shaft to his hard shaft. Tyler turned, confused for a moment until he saw the thick white cream dripping from the head of the anthro's shaft. The former human licked his lips, unable to resist. Every fiber of his being told him that the shaft before his eyes was the culmination of his destiny. He craved having it, not just in his mouth but in his ass and his pussy as well. Tyler reached up, wrapping two paws around the shaft, holding it in place as his feline lips parted over the tip.
Rutuba growled happily, feeling the heat and moisture from the mouth slipping over his length. Tyler sucked and slurped on the thick head, working more and more into his maw. He appreciated his muzzle, knowing that the extended length gave him more mouth to encapsulate the cock in, but even so, Rutuba's cock was brushing against the back of his throat. Tyler relaxed his throat as much as he could, letting the shaft probe deeper. Ty took one last deep breath before he relaxed completely, letting Rutuba's cock push into his throat feeling the hot and muscled depths of his throat. Rutuba made all manner of noises, sliding his shaft deeper and deeper. After being bred for mating, he was finally feeling as if he was taking advantage of his gifts.
The anthro cheetah started gyrating more, sliding back and forth in Ty's throat as if it was a pleasure sleeve, picking up his pace... It was so hard to hold back. He was meant to breed, to be fertile... and his own gifts were already starting to rev into high gear. Ty murmured as he felt a hot wetness start spilling down his throat, pooling in his stomach. Ty shivered in delight before the strangest thing happened... his entire throat stated vibrating violently, a deep purr spilling forth from him. The purr had the most delightful side effect of stimulating Rutuba even more, encouraging even more pre to leak.
Tyler gulped the musky milk down with the same gluttony he had for the food, but Rutuba tasted so much richer. The fur that had been moving down his legs accelerated, moving down along his knees and then his ankles, shifting the joints to work for being on all fours or upright with equal grace. Tyler's bare feet flexed and his toes curled, but as they uncurled they stretched out longer, his heel shrinking away. Portions of the sole of his feet began inflating and swelling like the paw pads on his hands, but the blond fur spread even faster, sweeping in and across the foot, obscuring all the skin but the paw pads. Even his toenails disappeared beneath coatings of fur, but they emerged a moment later as thick toe claws.
Rutuba growled in pleasure, his shaft so hard it was practically impossible to get it into Tyler correctly with each thrust. He suddenly pulled out, splattering a spray of pre across Tyler's muzzle. Tyler slurped at it, letting out a murr of disappointment that the cock had been taken away from him. Tyler moved to nuzzle Rutuba's hip lovingly, pleadingly. Rutuba's cock practically begged to return to a hot orifice, but the male knew he had many more to choose from. He had turned Tyler into the ultimate form of mate, the perfect hybrid of male and female. He was fully both, capable of all sorts of pleasure. All one had to do was choose.
Tyler's tail swayed with anticipation as Rutuba moved behind him, reaching out to pet his furry ass cheeks. Tyler took a deep breath, steeling himself... not for the fucking he was about to receive, but because it wouldn't be instantaneous. Rutuba ran his hands all over Tyler's furry hips, trying to decide... but his instincts made the decision for him. He was a male, and Tyler had female parts. After so long, Rutuba would be able to mate properly. The cheetah man got a firm hold of Tyler's hips, his claws digging a little into the flesh. Rutuba brought the head of his shaft to the hybrid's juicy pussy, staying there for just a moment before he thrust forward. Tyler's back arched as he felt the hard shaft spear into his brand new orifice.
It was a most peculiar sensation to have a huge feline cock deep inside his body, but the more Tyler thought about it, the more wonderful it felt, as if that was his purpose. His own cock was starting to drip thick pre as he worked with the cock inside of him. Suddenly, without warning, Rutuba started to slide back. Tyler groaned, not wanting to have the cock removed. He flexed, using muscles he had never tried before. The hybrid's pussy clenched around Rutuba's meat, tugging and massaging it. Rutuba growled out in surprise before he thrust in, tugged back, and built up a momentum. The two cheetahs swayed back and forth in the effort of their love making, minutes slipping past in their sensual embrace.
The combined juices of Tyler's pussy and Rutuba's leaking cock build up until an amazing squelching noise grew louder with each thrust, Rutuba's meat churning their goo. Tyler was panting, purring, growling... his entire body was on fire with passion, but no where near as much when he felt his mate slam into the tight ring of flesh deep inside of him, his cervix. Tyler's eyes crossed before he suddenly pushed his hips back against Rutuba's thrust. The anthro growled in passion, slamming into the cervix more and more. All the while, his hot pre worked on the muscle before the cervix started to dilate.
While Rutuba's thrusts had been slamming into the cervix repeatedly, with one random thrust his head wedged into the hole. Surprised, Rutuba didn't pull back. Instead, he thrust harder and harder and ground his hips to Tyler's. His cock head wriggled in tighter and tighter before popping into Tyler's most intimate depths. Tyler's claws dragged along the ground as he adjusted to the presence, but... he knew he needed more and there was only one thing to do.
Tyler lifted his muzzle skyward, letting out the yowl of a female in climax, his call echoing into the jungle. All through his body, his muscles fluttered and tensed... both male and female organs were orgasming. His balls tugged up to his body, his cock pulsed and then erupted, musky cum spraying all over the ground while his pussy quivered and massaged Rutuba's length, the cervix closing tight around his shaft. The sensation was too much for Rutuba and the Anthro let out a yowl of his own before his shaft erupted with potent, hot, fertile cum, filling Tyler's brand new and fertile womb.
Tyler braced against the sensation, panting hard before he nearly collapsed. Still, he managed to stay upright, his breasts and belly swaying. As Rutuba's flow subsided, the anthro leaned forward, laying along the back of his mate. He leaned in to lick and nuzzle at Tyler's neck softly, both cheetahs purring loudly, their bodies fitting so well together. Tyler felt so loved, so complete, so content...
"So good, so very good." Rutuba whispered, a smile crossing his face, "Now that we've broken that hole in... let's fill your pucker before we go and find your friends... and show them all the fun we can have in the name of science." Rutuba whispered, a look of grin on his face.
