"Dean, this camping trip was a wonderful idea!"

A short, black-furred canine smiled up at her husband, a tall and fit puma. Ruth had a large and narrow muzzle and a long pelt, but no particular distinguishing characteristics of any certain breed. She wore a white blouse with ruffles over the buttons and a pleated black-and-white polka dot skirt, which stretched across her slim frame as she leaned up towards the shelf in the small general store, plucking a bag of flour from the shelf before depositing it in her shopping basket.

On the other side of the aisle, Dean grinned. "I'm glad you're enjoying yourself so far, Ruth," he said, "but I'm still a little worried about the weather. There was nothing in the report about rain."

Both turned to look out the windows of the small shop. Ominous gray clouds gathered in the distance, making the evening sun darker than it would be otherwise.

"Oh, you worry too much," Ruth said, grinning as her tail swished back and forth above her skirt. "It's going to be great!"

Dean smiled back and took a step closer. His rough flannel shirt and blue jeans pressed up against his wife's front as they squeezed together, muzzles meeting for a short kiss before they broke apart again. Dean growled deep in his throat and smacked his paw across his wife's bottom.

"I'm gonna check to make sure the car is full of gas. Meet you outside?"

"Okay!"

With a full tank of gas, camping supplies, and groceries, Dean and Ruth set off down the road in their open-top convertible. It was a small, fast, black car, and Dean's pride and joy. He was fanatical about maintaining the vehicle and spent hours in the garage of their house tinkering on it. The engine hummed along as they sped down the empty roads into the darkening night.

Dean glanced over at his wife. They'd been married five years now and were inseparable. He grinned as he watched the way the dashboard lights lit up her silky black fur and reached over, putting a large paw around her shoulders. She scooted across the bench seat and leaned into his side as the cool night air whipped overhead. The puma purred deep in his chest, almost as loud as the engine in Ruth's ears.

"Dean, look!"

Ruth pointed and sat up. About half a mile away towards the left side of the road, an imposing gothic castle came into view around the bend. The dark structure stood out against a large lake behind it. Tall, black spires stretched up into the night sky and Dean gawked.

"That.. that's new," he said, blinking. He'd driven this route several times to the campground, the last a little over a year ago. Could a structure so large have really been built in just a year?

"It's so pretty!" Ruth said, leaning over his lap to get a better look. "We'll have to drive by again when it's light out!"

A dirt road ran from the paved surface they drove on down to the front gates of the castle, which were just barely distinguishable in the dark night. The ominous structure sent a shiver up Dean's spine. The feline tightened his grip on the wheel and focused on the road. Ruth liked strange things sometimes.

Fat raindrops pelted them all of the sudden. Ruth gasped as the cold water soaked into her fur down to the skin and she pulled back, holding her paws over her head.

"Oh, hold on. I should have put the top up earlier," Dean said, pulling the car over to the side of the road. They were about level with the castle - the turn off to the dirt road was just a few dozen feet ahead of them.

The rain poured down as, seconds later, the storm broke over them. Dean cursed as he struggled with the top, hoping he had enough towels to dry the seats. He shook his head, trying to shake the water out of his eyes as he pulled the hood up and over, then latched it into place on the driver side. He was on the passenger side as lightning cracked and boomed overhead. The rain pelted him as Ruth pulled some towels out of the backseat and dried off her fur and the seats inside the car.

"Damn weather reports always get it wrong at the worst times," Dean said once he'd slammed the door shut. He took a towel from ruth and gratefully dried his ears and face. "Hope this doesn't last long."

"Maybe it's not raining at the campsite," Ruth said, taking the towel back from Dean when he'd finished.

After Dean changed his soaking shirt for a dry sweater and wiping down the seats of the convertible once more, they set off in the darkness, going slow as the road narrowed and turned to dirt. A sheer face of rock stretched high over them on the right, while on the left the ground banked towards the castle and lake about a quarter-mile or so off the main road.

The suspension argued and creaked as Dean sloshed the car through the smallest puddles he could see through the dim illumination provided by the headlights in the battering storm. More lightning cracked overhead, sending a massive boom that drowned out the radio momentarily. Ruth clutched at Dean's arm as another bolt of lightning struck the top of the ridge above them, illuminating the night as though it were day.

"Look out!"

"Hold on!"

Ruth screamed as a huge tree crashed down on the road in front of them. The upper branches blazed for a few moments before the drenching rain put them out, casting the road ahead into shadow and darkness. Dean stomped on the brakes, but they were already wet from the puddles. The metal ground as the car trundled forward, hardly slowing at all as Dean cranked the wheel to the right. There was no way to avoid hitting something at this point. The right hand side of the car ground against the rock wall as both passenger-side tires shredded. The rims struck rocks, tearing the wheel out of Dean's fingers as the linkages beneath broke.

Bouncing off the rock wall, the car swung in front of the tree, slowed a little more as the branches smashed through the windshield and broke the passenger side windows. Ruth screamed again and clutched at Dean's side as the puma tried to get control of the car without any luck.

The wheels went over the bank and stuck out as the backend wobbled, rising off the ground nearly a foot before rocking back. The groan of the metal and the scraping of the metal added to the blasts of lightning and thunder lighting up the sky and revealing the tree-filled descent down the hill towards the river.

"Deeeean!"

The canine's shriek pierced Dean's ears as the car tipped forward. The broken wheel twisted in the feline's paws as the front wheels dragged on rocks, roots, and bumps, sending them airborne several times. It was through sheer luck they didn't hit any trees as they picked up speed, careening out of control down the hill as their headlights flashed and flickered, illuminating the danger of the trees as huge trunks whisked by inches from the car, ripping the side-view mirrors clean off.

Somehow the car made it to the bank of the river without hitting any trees, though sideswipes on both sides left the metal dented and torn. The front lifted as they hit the upturned bank of a small stream feeding into the lake about a hundred feet from the dark gray walls of the castle itself.

As their car launched over the six-foot-wide stream, lightning lit up the tableau: the spinning wheels sending mud and water spraying, the two figures inside slamming into the roof of the car, the reflection of the jagged bolts of electricity reflected in the dented and scratched paintwork.

In an instant, the car slammed into the ground nose-first, flipped over, and crashed into the wall of the castle with a shocking thud.

For a long time, there was nothing but the sound of rain and thunder. A light suddenly flashed into Dean's eyes. He tried to blink, but even his eyelids wouldn't function.

"Big accident, big accident," he heard a voice mumble. "Must fix, should be easy, fix it right up!"

The light swung towards Dean's eyes again, but the puma's head hung limp.

"Hmm. Maybe not so easy."

* * *

Ruth stared at the ceiling. It was made of dark stone bricks mortared together with a slightly lighter jointing compound. The bricks were rough-hewn and uneven, but appeared solid. Long electric cables hung from regularly-spaced hooks stretching across the ceiling from one side to the other. Dozens of bare, yellow light bulbs flickered, casting a pale glow around the room.

The wolfess tried to move, but something was wrong. She could feel her arm twist against restraints, but only one arm moved. She tried to wriggle, but she weighed too much. Her body felt heavy.

A bright white-furred face popped in front of her eyes, which widened in shock.

"Shouldn't be awake yet, nope, shouldn't be awake. Too early."

"Wha... who..."

"I'm Doctor Morante, that's my name, Doctor Morante."

"Where..."

"You're at my castle, you're at my castle!"

The ferret kept interrupting the wolf's questions with her high-pitched sing-song voice. Ruth's eyes peered to the side, seeing bubbling vials of blue and red and yellow fluids, along with smoke and gas. To her horror, she realized the tubes running out of those bubbling bottles headed straight for the table upon she she lay immobilized.

"Time to sleep, time to sleep..."

The wolf's eyes closed, the last word drifting from her lips as her head slumped to the side.

"Dean..."

Ruth's eyes snapped open the next instant. She felt alert, awake, and healthy. A low growl rolled through her throat as she crouched against the wide tree trunk, nostrils sniffing and scenting the air, tracking the prey. The wolf's large paw clutched the heavy stone-tipped spear in her paw as she crept forward through the undergrowth, large paws sinking into the loam without a sound.

The wolfess glanced down at her body. It was different, but it felt normal. The large and muscular lupine body stretched towards the ground. She liked being so tall.

The prey!

She pulled back her arm as the bushes and trees and the blue sky and warm sun around her melted towards the tip of the spear, before she too fell into the spinning vortex of colors. But she wasn't worried.

The colors suddenly stopped moving, but they'd been rearranged. She looked around, wondering where she was. A broad and open meadow full of tall sweetgrass and flowers under a bright yellow sun. Ruth flicked her tail across her flanks and then smoothed her fingers over her brown hide as she trotted through the field. She didn't have a sense of purpose, but neither did she feel unease about that.

Another figure approached through the meadow. Ruth stared, then ran faster.

"Dean?"

The other figure yelled something but she couldn't hear.

"Dean!"

Heavy hooves tore into the grass, ripping up clods of dirt and flowers as she charged forward, breathing hard, heart pumping hot blood that rang in her ears as the far-off figure came no closer despite her efforts.

"Deeeean!"

* * *

When Dean woke up, he kept his eyes closed, enjoying the sound of Ruth's steady breathing next to him. Just a bad dream, he said, trying to keep his heart from pounding. Just a bad dream. He stretched his tongue out, curling them around the large tusks pointing down his chin.

Wait... tusks?

"Dean?"

Dean mumbled something, but it was hard to think. He kept feeling... strange. Like someone else was pushing up against his head, but there was nothing physical. Like his head was too full of thoughts. But there were physical oddities as well. He could feel the tight weave of canvas straps pinching into his arms, chest, belly, and legs. They were holding him down and in place, but why? He couldn't even move his head, which was fastened in some sort of padded clamping device.

The sabretooth tongue slid across his large fangs again. His whole head felt fuzzy and his tongue was much longer than before, matching the growth of his teeth. He panted as he tried to lift his arm, to pull the strap around his throat away. He felt too vulnerable, too exposed, but his arms wouldn't work.

"You two are stubborn, very stubborn," a high-pitched voice said from somewhere past the sabretooth's head. Dean pushed against the restraints, but he felt so heavy... so tired...

A white-furred face with a pink nose and bright green eyes peered down at him. He could just make out that she was a ferret through his blurry vision.

"A new body needs time," the ferret said. A finger reached out, tapping the sabretooth on the nose. "Time to adjust and build the proper pathways for your minds. Back to sleep, back to sleep, must increase the dosage..."

"No, wait... what... who are you?"

Dean's throat felt strange. His voice, despite cracking through his dry muzzle, was deeper than before. His nostrils twitched at the scent left by the ferret's white-furred finger.

"I'm the doctor, I'm the doctor," the ferret said in her peculiar sing-song cadence. "You're the patient, must get rest."

"Ruth..."

Dean's fingers pressed against his stomach. His fur felt funny for a moment. Something scraped over his chin. He shook his head. Kept forgetting about those tusks.

The sabretooth crouched low, an arrow in his left paw, a bow in his right, and a quiver the only article of clothing on his powerful, lean body. He sniffed and scented the air, tasting for his prey.

The feline's long tail flicked behind him as he stepped around the boulder, moving into the open sunlight of the desert, pulled back his arm, and released the air, all in one smooth and fluid motion. The arrow screamed forward and tore through the colors of the yellow sand and the bright blue sky, pulling them with the chiseled stone tip until they rolled into a small, world-enveloping ball of colors into which Dean found himself falling from above.

He landed in a large meadow, the shock of the impact absorbed by the heavy hooves at the ends of his massive legs. The stallion's nostrils flickered as he smelled the sweetgrass and flowers. He tossed his large golden mane and whinnied, trotting through the field in a random direction. It stretched on forever and ever, but that didn't worry him.

A figure in the distance caught his attention.

"Ruth?"

Dean ran, pumping his massive thighs, digging his hooves into the earth as his long tail and mane stretched out behind him. His arms shoved forward and pulled back as he accelerated.

"Ruth!"

The figure didn't come any closer despite his efforts. She faded further into the distance. Even though Dean couldn't get a clear look, he knew that was his wife.

"Ruth!"

The sky above darkened to black and a lancing pain cut through Dean's shoulder. He twisted and fell, plowing his head and opposite shoulder into the ground.

Another body fell beside him, a mare with the head of a wolf. Dean licked his tusks, wetting his dry muzzle, as he stared into the eyes of the large and ferocious wolfess, his wife, who stared right back.

* * *

"Wake up, wake up, wake up!"

No, Dean thought. Go away. I don't want to get up.

"Wakeupwakeupwakeup!"

Tiny, sharp teeth latched onto Dean's left ear. His eyes snapped open and his muzzle twisted, massive fangs on full display as he roared and tried to twist away, only to be stopped by tight canvas straps keeping his body cinched tight to the table. The confused sabretooth blinked, but his vision was blurry and he felt disoriented. The bare bulbs hanging from the ceiling above him twirled and spun as he felt a series of strange sensations, each one worming into his brain and demanding recognition.

Dean's ears twisted as, a few feet away, he heard the "Wakeupwakeupwakeup!" chirp repeated, then a pause. The sabretooth winced at the howl of shock that echoed off the ceiling from next to him. He turned his head to the side, barely able to move even that small amount. His tongue draped over his panting lips as he watched a large wolf's muzzle push outwards, lips forming an "O" as the white-furred ferret pulled her muzzle back from the large, triangular, black-furred ears on top of the wolfess's skull.

"R... Ruth?" Dean gasped.

The howl cut off and the large, black-furred skull turned to the side. The eyes that stared back at Dean were those of his wife, he knew, feeling it deep in his gut.

"Dean!"

An electric winch started up. Before the sabretooth and wolfess could say anything else, they realized a large mirror tipped forward until it hovered over them. Next to it, a projector screen contained intricately detailed black and white sketches done with exacting information listed along the margins. The sketches showed Dean and Ruth from the front, back, and sides, with dozens of arrows, incision marks, shorthand jargon, and scratched-off ideas.

"Ahem!" the ferret said, standing between the mirror and projector on a small stool, leaning over so she could look down at her patient. "You must have many questions, many many questions. I can explain, I can explain!"

Dean and Ruth didn't appear to hear a word the doctor said. They both stared at the mirror, muzzles open equally in shock at the view. At first, Ruth didn't believe it. A trick of some sort, smoke and mirrors, something, anything that wasn't what stared back at her.

Her long and silky black fur remained from her neck up, but her muzzle was larger and toothier. Her nose picked up strange new scents as she looked at herself with familiar eyes, though the massive and sensitive ears were far different than the naturally flopped-over pair she used to possess. Additionally, a diamond-shaped patch of white interrupted the black fur between her eyes. In the center of the patch, a unicorn horn spiraled out to a wicket point almost a foot in length.

Dean, beside her in the reflection, was similarly different from the neck up. His previously short golden-brown fur was longer and much shaggier around the neck, almost mane-like, while his muzzle had grown considerably larger to allow for the nearly eight-inch tusks protruding from his upper jaw. They curled over his large chin, ending in points just below.

"First slide, first slide," the ferret said. She ran a paw through the tan fur on top of her head as she grinned down at them with excitement. "Initial notes. Had to assess the situation and plan a course of action. Many theories, many hypotheses, but I found a solution!"

Her paw lifted and pressed a large red button on a wired control panel. The slide flicked over to the next image of a massive stallion. According to the key on the side of the detailed drawing, he was nine feet tall plus a few extra inches for the ears atop his head. In the corner of the slide, the ferret had scrawled the word "clone experiment #3". The technical drawing of a planned experiment included a smaller drawing of the ferret herself, along with a diagram with helmets and wires.

"Planned this experiment for myself, experimenting for myself is a fun hobby, fun hobby!" the ferret said, her voice pitching higher as she talked more quickly in her excitement.

Dean half-listened, but most of her chattering missed. He stared at the mirror as he looked at himself from the neck down. Instead of his chest, the body of a massive stallion stretched out in front of him - the same body, he realized somewhere in the back of his conscious mind, the ferret showed on her slide.

The most unusual feature of the stallion's chest, however, was that Ruth's head also attached to it. Dean turned his head to the side again, a dream-like smile on his muzzle.

"I'm going to wake up soon, right, Ruth?"

The wolfess didn't reply as she stared at the mirror. The white straps of canvas added stripes across the massive equine torso. The first covered the junction of their necks with the shoulders, while the next squeezed into a pair of oversized mammaries. The strap squeezed down, stretching around the plump pink nipples protruding from the otherwise dark chocolate brown hide. Her large orbs couldn't be quite squeezed together tight enough to eliminate the gap between the nipples, between which the strap flexed and strummed like the string of a guitar.

Another strap held down their shared hips, then a series of straps down the large, powerful equine legs. Because of the way the ferret leaned over them, neither Ruth nor Dean could see the warm, pulsing weight between their thighs.

"But more important to save you two," the ferret said, pressing the button. A third slide appeared, showing a detailed and slightly gory view of the clone body with an incision across the neck, then detailed step-by-step instructions on how to bifurcate the necessary blood vessels and reattach them to the incoming necks. Fortunately, the scientist went to the next slide quickly.

"And here is the result. I, Doctor Morante, Doctor Morante, have successfully grafted not one, but two heads onto a single host body, a never-before accomplished feat in science!"

The ferret beamed down at them, eyes wide with a huge smile on her face. When the sabretooth and wolfess didn't react, she pouted a little.

"Well, anyways, because of the delicate nature of the operation, operation, it's easier to work on someone large than small, large than small," Dr. Morante said. She pointed at the slide where Dean and Ruth realized she'd drawn in their original heads, which looked far too small and tiny on the massive stallion torso. "Had to go large, largest common denominator! And fill in gaps where damage was too extensive."

She pointed at a detail of the wolf's skull where the unicorn horn was inlaid to replace a fractured bone and then pressed the button again.

Dean groaned as the warmth between his thighs intensified. He looked over at Ruth and realized she experienced the same surge of lustful arousal as he had. He tried to move his arms again, but when he looked back in the mirror, he realized why they'd felt so strange.

Not two, but four arms stretched out from their equine torso. Ruth realized it at the same time as their shared heat continued to build, amplifying and building as their brains rewired, building the new connections to bridge a single nervous system across two functioning and independent brains. Their heart thumped erratically before settling into a rhythm as they came into sync with each other, which made curling and uncurling each individual paw easier. The upper set of arms wasn't equine, but feline, covered with a shaggy golden pelt from the shoulder down to the tips of the fingers and retractable claws. Powerful biceps and triceps flexed outwards, pulling the shaggy pelt tight, as Dean tried to get free of the creaking straps.

Ruth found the lower set of arms as familiar as Dean found the upper. Covered in a rich, silky coat of black fur, the lupine arms were just as muscular and large, with a fearsome set of black claws at the tips of her fingers. She flexed them into her paws and tried to stretched them towards the canvas straps, but she couldn't reach them yet. She just didn't have the strength or the manual control of her digits yet.

"Had to make a few adjustments, just a few adjustments," the ferret said, moving on to the next slide. Dean and Ruth didn't pay attention as the ferret discussed several additions and enhancements she'd made on the fly - the extra arms, the oversized torso, and the knot. Dean's eyes widened when he finally looked away from the reflection of his shared body and saw the large, true-to-scale drawing of his new body from the side. A massive equine maleness stretched out and away from the hips, accompanied by an equally oversized pair of balls. The ferret's drawing shaded the sheath and testicles a dark black. Upright, it would stretch past the increasingly sensitive nipples squeezing and stretching against the canvas straps.

As though on cue, an enormous horse-stalk flopped into view past the reflection of the back fo the ferret's head in the mirror. The meaty length draped across the hard, muscular belly Ruth and Dean shared before twitching and growing, straightening up and hardening while pushing in between their breasts beneath the strap.

The wolfess moaned along with the sabretooth as their arms pulled at the restraints again, tugging and jerking as their swollen arousal throbbed between their oversized breasts, held warm and tight as the sloshing orbs slid back and forth, making them quiver and gasp even louder.

"Next," the ferret said, oblivious to their growing arousal, "I had to give time to heal, so it's been two months, two months!"

The words somehow snuck into Ruth's brain, managing to find their way past the waves of heat and pleasure coursing through her body.

"Two... months?" she gasped.

"Yes, and now that you are awake, the hormone surge begins! Hormone surge begins!" the ferret squeaked, watching from above as the stallion-shaft plunged further between the tightly packed cleavage, putting additional strain on the strap, so much that it clearly showed the outlines of the plump, hard teats capping each mammary. "Shouldn't last too long, too long, but expected. Body must adjust, minds must align, might be uncomfortable."

Ruth gaped at her reflection. She wanted to be horrified, to be disgusted, to be angry, but the heat between her breasts, the heat between her thighs, and the growing feeling of connection with the sabretooth as their minds synchronized overwhelmed any other emotion. Her head tipped back, gasping, howling, as pulses of thick, clear pre-cum oozed in thick gushes from the upper part of her cleavage, squeezing through the dark brown hair and hide before dribbling down to the metal table beneath them between their heads.

Dean was in much the same way. He could feel a new feminine warmth tingling up his shared spine and shuddered. It was a heat that demanded attention and his fingers curled as he pulled on the straps again. His biceps bulged on all four arms as Ruth joined in with him, both attempting to move them at the same time.

They took twin breaths, sucking in air. Their huge torso expanded, stretching against the strap holding their massive arousal tight inside their warm and squeezing cleavage.

"And next, when the hormone surge is finished, you are cured, you are cured!" the ferret said. She grinned at her own sketches showing the tall, two-headed sabre-wolf-horse standing next to an outline of herself, demonstrating the projected difference in size. She didn't notice the sounds of cloth snapping - first one, followed by a pair of groans and a wet thud, than half a dozen more. "You should have full motor control within a few houuuuu!"

Four huge arms reached out, canvas straps dangling, broken and torn. A massive equine stalk jutted from the husband-and-wife's crotch, with a thick canine knot causing it to extend even further as it squeezed from the tight, black-skinned sheath. The ferret squeaked as she felt twenty eager fingers tug her right off her perch on the stepladder and drag the front of her lab coat across the broad, flexing expanse of highly aroused stallion-shaft. It throbbed around her arms as claws tugged at her hips, thighs, and belly, pulling her up towards the tip.

Rather than feet, Dean felt a pair of heavy hooves slipping against the table. Large, long-haired fetlocks fell over the glossy black hooves as he worked with Ruth to pull the squirming ferret closer, until drops of musky pre-cum drizzled over the tan patch of fur between her ears. Morante's bare feet slid down the stalk, looking for purchase, and inadvertantly shoved down on both sides of the veiny, throbbing knot at the base.

The shock of pleasure from the touch made the thick stallion-maleness flex. Ruth and Dean both groaned, eyes closing, as the sensitive new knot swelled outwards even larger. It made their already massive new shaft even longer, so that the flared tip rubbed messily past the generous gap between their large breasts and dribbled between their necks as they pulled the ferret in along with it.

"Nnnghh... Dean..."

Ruth groaned as a flush spread between her legs. The fingers of the black-furred arm on the left side slid down and pushed beneath the oversized, black-skinned testicles draped over their thighs and pressed between the warm, aching pussylips, sending another shock of pleasure up their shared nervous system.

"Oh, Ruth!"

As their brains built new pathways, their nervous system linked them more closely together, unifying their systems to work in sync with each other. The ferret dashed to and fro, checking levels on various electrical instruments as the huge new hybrid learned to control a brand new body. Ruth and Dean moved their arms first, slowly discovering how to share the responsibilities for all four limbs between them, but within minutes had one set pawing at their chest and the other pair wrapped around their oversized stallionhood. Ruth's lupine muzzle turned up and her head back, scraping the pointed tip of the unicorn horn spiraling from her skull across the metal table.

"Yes, yes, hormone imbalance intensifying, but will pass, will pass," came a muffled mumbled from the ferret, whose face squeezed in against the huge tip just beneath the flare, before three arms dragged her down to the base, only to shove her up again, using her to stroke their arousal as Ruth's fingers explored the sensitive lips hiding beneath their aching balls.

Dean's tongue hung over his lips as he experienced every pleasurable moment twice - from his perspective and from Ruth's. Their shared, empathetic bond intensified as they pumped their hips, pounding the overgrown stallion-shaft. It didn't take long for them to figure out they could also use the large, swollen mammaries jiggling from their torso, and soon their paws squeezed the huge orbs tight as the tingling, electric pleasure amplified further, pushing their rational minds to the side as a primal lust took over. Instinct drove them now as their thick, knotted horsecock stroked deep between their breasts, carrying the squirming and wriggling ferret with it. Claws ripped away the white-furred female's lab coat, revealing the simple black cotton bra and panties beneath.

"Dean!"

The sabretooth turned his head to the side, meeting his wife's muzzle. The two heads kissed, leaning in together as their arms pulled the nearly-nude ferret's slim, firm body against their aching arousal, dragging her hips higher than ever until she was sitting rump down against the massive flare. Her thighs stretched to the sides as she felt the pressure intensify on her legs.

"May have... miscalculated... the effects of the hormone imbalance... and tensile strength of canvas," Morante said, her voice rising even higher as the huge chimaera's grip tightened. "Definite miscalculation!"

Dean and Ruth's lower black arms pulled the flexible ferret's legs to the sides while the other two supported her hips. The flare of their shaft pushed upwards slowly, gradually dimpling the ferret's thighs as her gasps and squeaks intensified, growing louder and louder.

Dean growled, Ruth howled, and both closed their eyes as their lips pulled apart. The huge flare stretched in, pushing outwards immediately against the ferret's walls as her legs trembled in the powerful chimaera's grip. The stallion-shaft flexed, bucking in another few inches, the huge veins compressing as Dr. Morante's belly distended.

The muscular horse belly shifted, thighs straining, as the huge hooves and white fetlocks stomped over the floor. Dean and Ruth stood up, all four arms controlling the squirming ferret impaled on their huge new arousal. Dean's ears took him to almost nine feet tall, while Ruth's unicorn horn managed to go just a few inches past that.

They turned around and let their huge maleness slap down across the metal table, causing Dr. Morante to let out an "oof!" as her shoulders hit. The huge staff lodged inside her made her groan as an orgasm ripped through her body. The ferret clenched, gasping, thighs quivering as all four eager, clawed paws groped at her body. Dean and Ruth turned their heads together, kissing again, as they leaned over, pinning the white and tan ferret beneath their chest. Morante's fingers scraped over the sides of the huge swells as her face disappeared between them.

Ruth's black-furred wolf arms tugged on the ferret's legs, dragging her roughly down the intruding maleness, further stretching her stomach as she made out with Dean. The sabretooth's eager growls sounded deeper and heavier coming as they did from such an expanded, muscular torso. Muscles bulged along their arms as their claws dug in, keeping a firm grip on the squeaking, wriggling ferret beneath them.

The intense pleasure as they sunk more than half of their horseshaft into the ferret made them drool over each other's lips. Their chest seized up as they pushed in harder yet, unable to help themselves as the ferret's muzzle cranked open in a voiceless cry. Her stomach bulged obscenely, stretched up to the point it was shoving between the oversized, dark-brown hide coating the chimaera's breasts.

Dean and Ruth's thrusting resumed within moments. Their powerful lower body stretched to the floor, huge thighs and immense calves running down into the broad, glossy black hooves and long fetlocks. An enormous pair of buttocks tightened below a flicking horse tail as they surged forward, shoving and pumping and groping and squeezing, unrelenting as the ferret's body stretched and stretched to accommodate the impatient girth of their oversized, flared, and knotted stalk.

That huge knot is what set off the doctor's next orgasm. She cried out, loud and clear this time, as the massive ball of flesh stretched her pussy even wider. Another ripple of pleasure, and another, and another, each time the stallion-sabre-wolf grunted and pumped against her. Her legs ached as the fingers clutching her ankles pulled even harder. Morante's muzzle opened, staying that way, as the pressure built and grew, until her whole body wriggled against the heavy breasts squeezing down against her.

"One," Ruth gasped, fixing her grip on the ferret's thighs with her black-furred arms.

"Two," Dean replied, making sure his hands were tight around the ferret's fuzzy white ankles.

"Three!" they both shouted, eyes closing as their arms pulled and their hips pushed.

A loud, wet slicking sound echoed through the laboratory, bouncing off the stone and mortar walls. Dr. Morante's arms stretched and squeezed around the sides of the huge breasts pinning her shoulders and face down, unable to reach past them to grab the equine shoulders above. Beneath Dean and Ruth's shared belly, the ferret's flexible belly wrapped around the huge knot, clenching and spasming as one orgasm after another send shocks of pleasure through Morante's brain, until she was hyperventilating beneath the overwhelming orbs.

Dean and Ruth pressed their temples together as they came. The glorious release opened up all new pathways between their brains, causing a feedback loop of pleasure that made their whole body flex and tense. Each motion of their lurching arousal as it throbbed inside the white-furred ferret's bloated body caused the cascade to intensify until both Dean and Ruth were screaming with pleasure. Morante, held tight and unable to move as her belly and chest filled and stretched, gurgled as excess stallion-seed filled her throat. She was almost three feet high from the top of the table to the peak of her rounded belly, but as the muscular abdomen of the stallion-core squeezed down against her, the pressure caused another peak of pleasure. Thick, warm seed splurted from her open lips, fountaining into the cleavage of the stallion's breasts before drizzling back down around Morante's face.

Dean took control of the hips, forcing them to push and pull, but the huge knot simply dragged the ferret bodily up and down the metal table, smearing seed along the smooth, shiny surface. When Ruth leaned their shoulders back, their huge maleness flexed upwards, lifting the dangling white ferret into the air. Morante's arms squeezed around her front, where her small breasts were pulled nearly flat by the stretching being done to her surprisingly flexible body as more cum gushed from between her lips, thrown outwards as her shoulders swung forward until she bounced off the stallion-sabre-wolf's chest. She tried to cling to the huge orbs, but couldn't get a grip with her messy paws before the muscular golden arms reached forward and draped over her shoulders, shoving her down and holding her there. The lupine arms reached lower, around her bloated and distended belly, to grope at the cheeks sucking in around the base of the shaft below the knot.

For almost half an hour, Dean and Ruth ravaged the ferret. Their knot didn't go down a bit as they pumped and flexed, stroking short and hard as they could as the ferret's body swelled larger. Even her breasts returned, sloshing as the stallion's potent seed dumped load after load inside her. She gargled and gasped for breath between pulses, arms pinned to her sides as she was pushed between the heavy breasts. Dean's hands squeezed them around her more firmly as they thrust their hips, titfucking themselves with the squeaking, gasping, groaning ferret.

Eventually the hormone-induced lust passed. Dean and Ruth kissed each other again as they leaned against the stone wall, all four arms pressed out against the mortared joints. The ferret sat on their knotted stallion-shaft, twitching and groaning as her arms hung limp by her side. Thick seed dribbled from her lips and down her swollen chest as her aching pussy clenched weakly around the invading knot. The chimaera didn't stop kissing themselves as their knot shrank gradually, eventually getting to the point where Dean's golden arms could drag the panting ferret off. Morante wriggled weakly as a half-dozen more intense, short orgasms punched their way up her battered and stretched body. The massive stallion-cock dropped low, a flood of thick and potent stallion-jizz gushing out once the flared tip squeezed out of her clenched hips. Morante's belly and breasts jiggled, sloshing back and forth when Dean and Ruth laid her down on the examination table.

The chimaera panted from both heads before Ruth turned to look at Dean.

"Dean... what are we going to do?" she asked, reaching one paw up to stroke the sabretooth's cheek as a few twinges wriggled up their enormous maleness.

"I'm not sure, but at least we have each other."

"Total success, total success," Dr. Morante said through bubbles of seed push past her lips. "Highly important work to do, work to do..."

"Oh, Doctor!" Ruth said, realizing the state the stretched and abused ferret was in. "I'm so sorry! I... we... we couldn't help ourselves!"

"Are you okay?" Dean asked.

"I'm fine, I'm fine, must get *urp* back to *urp* work, of course, of course," the ferret said, a dreamlike babble of nonsense and thick white stallion-seed drooling past her lips. "No trouble at all, no harm done, no harm done..."

The sabretooth and wolfess glanced at the shivering, jiggling ferret laid out on the table before turning back to each other. Their arms lifted, grasping at the back of each other's head with one set while the other set went back to their achingly large nipples. Their muzzles squeezed in close as the humongous, veined length of stallionhood straightened back up, soon filling out and quivering with a renewed need. The stallion's body supporting their heads was capable of surprising acts of stamina as fresh heat filled their body and minds.

"Dean," Ruth gasped, feeling the powerful maleness occupy her every thought once more, "I don't... I don't mind this."

The sabretooth's head leaned over, brushing his flicking ears against the side of the black wolfess's face. "Me... me either," he gasped. "I can feel you... so close all the time now..."

Their growing arousal prevented more talk. The black-furred pair of lupine arms reached out, grasping the ferret around the hips and rolling her onto her bloated belly before the medial ring of the flexing arousal jutting from Dean and Ruth's hips slid between the plump ferret rump cheeks, forcing the twisting tail out of the way. One of the sabretooth arms pushed into the ferret's sloshing belly while the other reached around and down, between the eager chimaera's thighs, teasing fingers across the warm and wet pussy lips aching with need.

"Enormous success! Enormous succeeeek!"

Several months later...

"Ouch!"

Dean reached up with one of the upper arms and rubbed his forehead. He and Ruth had been joined together for a long time now, but sometimes they still forget they were much taller than they were before. For not the first time, Dean wondered why they didn't wrap blankets around the wooden door jams throughout the castle.

Ruth giggled as she straightened her neck. She'd ducked her head to the side to avoid getting whacked.

"Think it's funny, huh?" the sabretooth said, his voice growling playfully as he reached up and tweaked the right nipple. Being on Ruth's side of their shared body, she felt it slightly more than the left.

"Ah! Oh, you tease!"

Their arms twisted and curled around their enormous chest as they sauntered through the castle towards the doctor's laboratory. The huge length of stallion-shaft waved in front of them, half-aroused and spilling from its sheath, though their enormous knot remained firmly inside for the moment. They pushed open the door to the lab with one large hooved foot, revealing the backside of Dr. Morante bent over a workbench.

"Ah ha!" she squeaked, standing up suddenly. The small ferret whirled around, grinning madly, a by now familiar glint in her wide green eyes.

"Something new for us to test today?" Ruth asked, flicking the horse tail she shared with Dean behind her.

Ruth and Dean gave up on the idea of being separated a few weeks after the they regained consciousness. Dr. Morante explained that there was simply no way to do it safely - for now, at least. And besides, Ruth loved sharing a body with her husband. They'd never been so close - literally - and feeling his emotions and pleasure only amplified her own.

"Yes! But not for you! It's for me, it's for me!" the ferret said, jumping from one bare foot to the other. Her plump belly jiggled beneath a stretched pair of white-furred breasts, evidence of her many, many trists with the overgrown stallion-shaft draping over Ruth and Dean's thighs.

"What's it going to do?" Dean asked.

"You'll see, you'll see! But you won't be so much bigger than me for long!"

The scientist tipped back the vial, downing the glowing blue contents in a few rapid swallows. Almost immediately, she hunched over, groaning as her lab coat stretched around her shoulders. Within a minute, the seams tore and the fabric ripped down the back, splitting in two.

Morante leaned backwards, growling and moaning as heavy muscles grew in along her belly, arms, and legs. Between her legs, above the puffy and well-used feminine sex, a plump sheath emerged from the pelt and fattened rapidly, matched by the testicles that soon grew in beneath. Her belly hardened as the protein in her stomach was consumed to accelerate her growth. Inch by inch she grew taller as the maleness hanging from her hips took shape, appearing more equine by the moment. She stretched her arms out, gasping as she gained more than a foot in height, enough to lift her head up to be eye-level with Dean and Ruth's plump nipples.

Ruth glanced at Dean, who was staring at the large maleness stretching out and down from the ferret's hips, impossibly wide and thick, though still not as large as theirs. On the ferret's generally smaller body, though, it looked disproportionate.

"Nnnnnow I am the top, I am the top!" Morante squeaked, grinning as, still growing, she squeezed up against the frontside of the chimaera. "Dean is interested, I can tell! I can tell!"

The sabretooth blushed and looked away, though he licked his lips and lifted one of the four paws he shared with Ruth, sliding it down the ferret's firm side. Ruth giggled as she felt their arousal build, especially between their thighs, as the anticipation of what the ferret was planning struck them both.

Before long they were bent over a table, huge shaft blasting ropes of thick seed across the floor beneath them, as the muscular little ferret's hips hammered away at them, stretching them out in all new ways. Dean loved it, head lolling, eyes glazed, as Ruth bit her lower lip and took over, shoving back and moaning as she felt the doctor's arousal still growing larger, thicker insider their body.

"What happens... if you... double dose?" Ruth asked, ever curious about the scientist's methods. She'd been learning a lot over the last few months while Dean focused on rebuilding the convertible out of the parts and scraps they'd managed to recover.

"Is a triple dose already! Triple dose already!"

As Ruth felt the thickness rub against their inner walls, triggering the first of many deep and fulfilling orgasms to come, the wolfess grinned at her dazed husband, still unable to move or speak as the pleasure hit him especially hard, being unused to the sensation.

"Complete success!" the wolfess said. "Complete success!"
