Original story: Special Delivery (2009)

* * *

Chris looked at the large machine positioned on the floor near the couch with suspicion. It had a large metallic pole that appeared to be bolted directly into the foundation and a wide green barrel attached to the top laying horizontally. The inside of the tube was padded with something that looked soft and rubbery, but it was colored the same industrial green as the solid padded outside. A bundle of cables wrapped in a waterproof casing provided power to a control panel laying on the coffee table from the wall, while larger hoses curled towards the open window. When Chris peeked outside, he saw a half-dozen fifty-gallon plastic water barrels connected to the splitter at the end of the hose.

Very unusual, but Chris knew how much his partner loved to play games, especially lately. No doubt this was some sort of new roleplay scenario. Though the number of barrels outside seemed excessive for a simple decoration. Still, Chris was game. He may not be as adventurous, but he still enjoyed a bit of spice now and again. Otherwise he wouldn't be in a long-term relationship with the cheetahtaur in the first place. Chris glanced at some of the framed photos on the wall. The oldest showed him with Ellynn when they were both around the same size, but about a year or so the pictures changed, and while their body language remained the same, Ellynn was now much larger and taller than her partner, covered in a rosette-spotted gold and white pelt, and capable of running - literally - down to the shops faster than Chris could drive thanks to a long and lean underbody and powerful feline paws. Up top, Ellynn's torso featured a smooth white-furred belly, heavy teardrop breasts, and a resting Cheshire face. The cheetah's fur pattern ran black around her eyes, lending a permanent smoky eye effect, and featured other typical cheetah markings around her muzzle and slender neck. Chris didn't think her sudden change was strange or anything - in fact, he and everyone else barely noticed other than to comment to each other about how much more cheerful Ellynn was lately, even if she sometimes had trouble getting in and out of tight spaces like the elevators at work.

The human followed the bundle of cables from the wall back towards the barrel and pole, wondering what it was the chee-taur was planning this time around. Surely the device wasn't meant for his use considering how high tall the supporting column was and how large the aperture was on the open end.

Chris wasn't very tall, so the mounted barrel was as high as his own chest as he walked around it, carefully examining it while also avoiding the cords and tubes running off the back. There was no brand name, just some serial numbers etched onto the pole, and no visible controls on the support column or barrel.

The control panel was connected by a strengthened cable wrap with a cord long enough to reach the couch. Chris picked up the tablet. There was a note on the front from Ellynn - just two words, “Try me!" in the cheetahtaur's distinctive scratchy handwriting. Chris smiled again and pressed the button to turn the tablet on. It recognized his thumbprint, but only opened to a static screen with dozens of tiny lines of data like “DEVICE SERIAL NO." and “SOFTWARE V. UPDATE" and lots of meaningless little numbers. At the bottom, in a larger non-system font, scrolling lines of text appeared.

“WELCOME, NEW USER! CUSTOM PROGRAM FOUND!

New user? Ellynn already tried the machine out? Too bad he wasn't around for it - he liked the idea of watching the big cheetaur on the mount. If he got a stool, he could make out with her while she was at it, even. Nice.

Chris grinned as he kept reading the screen.

“PROGRAM CONVERSION… DONE

The machine made a few small electrical noises as various bits of the insides hidden away inside the barrel sprung to life, then paused after cycling through a self-diagnostic. Chris's eyes widened as he watched the aperture rippling, as though something were kneading the heavy pink silicon from the inside. On the screen, the status updates continued to scroll.

“FINAL PROGRAM FAILSAFE IMPLEMENTED… DONE

Chris shrugged and pressed his thumb to the tablet. The screen flashed, then displayed a new message.

“CUSTOM PROGRAM INITIATED

ACTIVATING MOUNT… DONE"

The machine whirred to life again, but there wasn't anything to look at on the outside of it, so Chris picked up the sagging drawstring bag on top of the breeding mount. Inside, he found a stretchy piece of headgear that was meant to go over the top and sides of his head while holding a thick wooden dowel between his teeth. The silicone strap was smooth and stretchy, but was a little large for his head, especially over his face. The front of it was distended and a bit floppy with room to spare.

“A bit? Really?" he asked. Sure, he may have mentioned to Ellynn once or twice wanting to somehow introduce some fun equestrian-themed toys to their playtime, but he hadn't considered it necessarily for him to wear. He only had two legs, after all. “I mean… well… alright…"

Chris shrugged. He did enjoy these games, and he was insanely curious about what all this was for. He also liked the idea of wearing a bit, judging from the way he was showing off his excitement between his thighs. You didn't spend so much time with a taur without wondering what it would be like yourself, after all, Chris thought to himself. Maybe this was Ellynn's way of giving him a taste of what it was like. He grinned as he prepared by dragging a chair into the living room from the kitchen, then put on the stretchy headband and chomped down on the bit. As he stood on the chair and leaned forward, wrapping his arms around the barrel, the machine hummed to life. He could see the screen on the control panel light up and flash a message about “PROGRAM IRIS RUNNING - 0%" or something, but Chris's attention was focused elsewhere. As soon as Chris's soft cock got to the opening, gentle suction pulled him inside. He let out a gasp - the barrel felt insanely good and, despite being far too large for his relatively small maleness, tight and firm. The barrel whirred quietly as rollers within began to move and ripple, forcing the rubbery, warm padding to squeeze and rub so nicely that Chris's jaw fell open with surprise. He was hard within moments and both of his hands eagerly grasped the edges of the tube. It was far too big for him, but the machine adjusted itself automatically to provide the best fit, apparently, because his knees wobbled and the chair creaked as he thrust forward again and again.

“Oooh… oh, wow… nnngggghhh… oh my god…"

Chris gasped and moaned through the bit, drooling down his chin as the pleasure coursed through him. His balls squirmed forward like he was trying to fit them inside as well as the machine grew slightly louder, switching gears. The change in speed and intensity made Chris's eyes cross as he fell forward across the mount again. His legs dangled, barely touching the chair, as he wrapped both arms around the big tube while his chest and stomach spread across the smooth, padded curve. His legs kicked and swung as he thrust hard and heavy, sometimes missing entirely before he found the sweet spot again to get his grind on.

It just felt so good… Chris's mind fogged and he panted hard, breathing deeply and gasping as the machine worked his cock like nothing he'd felt before. Around his ankles, his pants stretched and pulled as he twisted his hips and pounded away against the sturdy device.

With his teeth biting hard against the dowel in his mouth, Chris was too distracted by what was going on down below to notice the change in his lips. Stretched and taut around the bit, they darkened into a deep shade of black, which was quickly followed by the same discoloration of his nose. His jaw protruded, stretching, while thin white fuzz formed along his rapidly darkening skin. The floppy front of the bit and silicone headband pulled and stretched taut, dragging the bit to the back corners of his mouth as his entire jaw stretched and flattened. His nose followed above, darkening and spreading wider, flaring as his tongue curled and lengthened around the wet bit holding it back.

“Nnnggh! Oooh, uuuck! So goooooo! Nnnnrrrrgghh… hhrrrrrr… rrrrrrrrgghhh!"

Human moans distorted into animalistic growls as his face stretched and changed. Thin white fuzz grew around his jaw and then thickened, forming a lush and deep pelt of fur. Soon, a deep and luxurious pair of ruffs around her cheeks and jawline, big enough to completely obscure his pale pink ears, spread both up and down, sealing the top of his head while quickly covering his neck and chest. A new pair of lupine ears pushed tip-first out of the top of his head, covered in more thick white fur like the rest of his transforming body. They flicked and twisted as Chris's eyes popped open, staring wildly as his hips continued to thrust and push as hard as he could.

Normally he'd never last this long, but normally he wouldn't be feeling so good that he didn't even care that his body was rapidly transforming. His cock jerked and dripped, though not a single bit escaped the warm, rippling suction inside the barrel. The machine was keeping him on the edge, modulating its response so as to not push him over, and his panting new muzzle let out an eager, lustful whine of need as he threw his hips forward again and again against the padded edge.

“Nnngggrhhhh!"

A fuzzy white growth emerged from above his bare backside as the thick fur spread down past his thighs. The wide, fluffy, pointed wolven tail flapped up and down with the movements of his hips as it lengthened further and further. The tail was far too large for Chris's half-human, half-wolf body. It was soon larger than he was, and could only tug back and forth across the floor as it draped down the backs of his legs.

Fortunately, the weight of the oversized white-furred tail didn't pull him away from the barrel. His legs were changing at the same time. The black socks around his feet stretched outwards before sharp claws tore through the toes, then the entire foot outgrew the fabric, causing them to peel off and fall in shreds to the floor. Wide, powerful lupine paws stretched apart, tearing the pants and underwear still clinging to Chris's ankles into pieces. He let out a groan as his huge paws, which were, like his tail, disproportionately large to his body, pushed against the floor, giving him all new leverage against the barrel. His legs were digitigrade now, unsuitable for bipedal motion, but as long as he could push his hips against the barrel, he didn't care how his legs looked. The bit crunched under his teeth as he whined and growled - the barrel's insides felt even tighter, hotter, slicker by the moment, and the electric shivering coursing through his body made it so hard to think of anything else.

Chris shoved his backside up with his arms, curving his spine as he felt a sudden tight, uncomfortable ache in his current position laying forward across the tube. Propping his torso up on his straight arms against the barrel below, he never stopped thrusting even as he felt his shirt draw up tight around his chest and shoulders. His spine stretched and cracked and grew, forming a joint at the base of his stomach where his hips used to be. Instead, his body quickly assumed a quadrupedal underside. Furry protrusions formed forelegs that spread around the girth of the barrel, clutching it with large paws similar in shape and size to the ones on his hind legs. His upper body leaned backwards, both of his arms clutching at his chest, as his swelling, stretching shirt pulled tighter yet around his growing body.

No longer human, Chris's lupine-taur body shifted and moved more fluidly now. His lower half thickened, growing in height and weight until his long backside and wide belly matched his big paws and tail. The dense, thick pelt of white fur coating his entire body ruffled and shifted as he clutched at the barrel with his forelegs and prodded himself forward on his hind legs. Between those rear legs, his testicles bobbed and swung, each orb significantly larger than before and similarly covered in a lush coating of white fur with an extra long tuft swinging off the bottom of the orbs.

Chris's ears laid back and his teeth crunched into the wooden bit in his muzzle as he felt the machine's inner core expand. His thick cock was bigger, heavier, fatter, but being as he was unwilling to remove it from the wonderful breeding mount, he had no idea just how large he'd grown. His muzzle sagged as he leaned his upper torso forward and gripped the far end of the tube with both paws, just between where his forelegs hung over the sides, and thrust hard enough to send vibrations throughout the entire house.

“Nnngghhhh… rrrff… fuuuuuuuuck!"

Chris's plush, fluffy white chest fur spilled around the neckline, arms, and waist of his shirt, which was still just managing to cling on to his flat chest. Though his upper body hadn't grown as big as his lower body, he still had a far wider set of shoulders and a bigger stomach than before.

The wolftaur's molars ground across the bit still stretching his black lips as his eyes clamped shut suddenly. He whined long and loud, then furiously stabbed his lower hips against the barrel, sinking his growing cock as deep as he could again and again. Tingles of electric pleasure surged through his swinging balls and thick shaft as he wagged his tail furiously. His cock felt bigger, thicker for sure, and as the machine's internal rollers and pressure massaged the length, he was sure it wasn't just the size that was changing about it. It felt so good that his hind legs buckled momentarily, and his hips pulled back, dragging his cock out accidentally.

“Nnnggfff!"

Chris's eyes widened as his forelegs scrabbled across the barrel, but he lost his balance and had to dismount. His feet padded a step or two back as he held his upper torso upright with some precariousness as he got used to his new center of balance. His tail, massive and fluffy, flicked out behind him as his quivering rear legs struggled to keep him upright. He was probably as tall as Ellynn by this point.

Carefully leaning forward, he reached out with his arms to hold himself up on the barrel, which was paused and flashing a request to continue on the control pad. Bending his upper torso over, he stared between his forelegs at the enormous, midnight black horsecock flexing under his long underbelly. The shaft narrowed only slightly beneath the fat, flared pink tip before fattening right back up on its way to the intimidatingly thick medial ridge halfway to the equally fat base. The thick white-furred sheath pulled back, exposing every inch of the monstrously big, hard horsecock. The bulging urethra trembled as a steady drizzle of clear pre-cum fell from the tip and splattered on the floor below. The large arousal was nearly the size of his partner's big cheetah shaft.

“Hnnnnggggghhhhh…"

There was a general rustling of fur and many more lustful groans as Chris quickly remounted the machine. The enormous shaft sunk down straight to the root and stayed there. The wolftaur sagged around the barrel. His eyes lidded over and drool ran from both corners of his muzzle as he squirmed his hind legs forward, luxuriating in the rhythmic, powerful suction and massage provided by the breeding mount.

“I picked a program I knew you would love."

Chris turned his head around and pitched his ears forward. His partner, Ellynn, stood in the doorway to the living room. Lean, powerful feline legs supported the cheetahtaur's lower body. A glossy yellow-gold pelt flexed across her flanks and the sides of her narrow underbellow, and was accompanied by a pale tan stripe along her belly. The stripe spread between her fore- and hind legs, covering the impressively thick sheath and balls tucked between. Ellynn's upper body was also nude. One arm crossed her narrow belly so that her broad paw could wrap around the side, allowing her heavy breasts to rest on her forearm. Her other arm bent at the elbow and teased a length of the long, wavy reddish-brown hair flowing around her shoulders.

“You look even better than I thought you would," Ellynn said. Her high, tight voice purred as she stalked across the room towards the groaning wolf, only to swerve to the side and move to the couch instead.

Chris shuddered. His new body did feel amazing, and he dug his fingers into his fur around his belly as he humped forward with his hind legs, driving himself to the root inside the machine again. He was so close, so very close, and knowing Ellynn planned it all like this from the beginning made him feel even hotter.

The cheetah-taur gracefully leaned into the couch, stretching out so that her four taur legs hung over the cushions while a pillow helped prop her upper torso on her side. In front of her, she tapped at the tablet, opening the program and checking the settings.

“Ellynn," Chris gasped. “What are you… hnnnggghh… doing?"

The cheetah's pale muzzle curled into a grin as she watched the wolftaur's heavy sac swinging between his hind legs. He was panting hard, clearly on the edge, and having a hard time holding onto what little composure he had left. Ellynn licked her lips and teased her fingers across the screen.

“How'd you like to stop being Chris altogether?" she purred. “And start being who you want…"

Bolts of pleasure flickered along the wolftaur's long spine. His tail bushed as he whined, then panted and leaned against the barrel, sagging as the machine's rhythm intensified. Despite all that, the choice was simple. Ellynn may as well have asked if he wanted butter on his toast. His head turned, casting his somewhat blurry vision towards the outstretched cheetaur on the couch. Chris's muzzle opened as he stared, first at her lean, furry upper torso, the curves of her shoulders and smooth arms, her taut belly and powerful underside, the long legs and furry white toes. His eyes particularly lingered on her hind legs, where the black-skinned length of cheetah shaft slowly stretched across the stripe of creamy white fur along her underbelly. It wasn't fully hard yet, but was still huge, easily the thickness of three of the cheetah-taur's lean legs put together.

“Yes!"

“Hold on tight… Iris!"

The cheetah's fingers tapped across the tablet, which flashed purple after a few moments and showed a new progress bar. Ellynn dropped it on the end table screen up, all Chris could see was the word “IRIS" and an empty progress bar.

“Huh? Who's I-"

The wolftaur's pelt stood on end. His torso leaned forward as his paws stretched out, looking for something to hold onto as a series of convulsive electrical shocks pulsed through his taurified body. His claws scraped across the outside of the breeding mount and across the floor down below as he let out a long, halting croon, nearly a howl. Light flickered behind Chris's eyes, momentarily blinding her with a flash. The wolftaur's whole body glowed from within, and then the progress bar on the tablet advanced part of the way.

The wolftaur's tail dropped, going limp, as the aftereffects of the pleasurable shocks left her knees - all four of them - trembling and struggling to keep her upright. Iris shuddered as the breeding mount rocked beneath her, and without hesitation, the over-aroused wolftaur's thickness plunged in again and again as though nothing had changed. She groaned and stretched her shoulders back, pulling herself away from the breeding mount barrel. Her fingers curled down her chest, stroking across the plump, sensitive nipples in all the thick, plush white fur. The small cups gradually swelled and she grunted with pleasure and excitement as they quickly overwhelmed her fingers.

Iris groaned. Her nipples felt so good, so tingly and sensitive. They kept growing and thickening until two pairs of enormous breasts jutted from her broad upper torso. Hefting them from underneath, Iris looked down at the impressive double set and shivered with lust. Between her legs, something else was changing. Her eyes closed and she huffed, gasping, as the amount of sensitivity between her flanks doubled in a moment, amplifying everything she was feeling all over again.

Next to her original transformed erection - thick crown, enormous knot, black at the base fading to a deep pink halfway down the long shaft - a second forced its way from her stretched white sheath. It shoved forward and found its way to the opening of the breeding mount, which opened quickly to adjust to the second shaft. Iris sagged forward as much as her huge furry balls did - the heavy orbs almost doubled in size as both enormous shafts plunged into the breeding mount.

Iris gasped and opened her eyes when she felt something warm and furry drop across her backside. Large yellow-gold paws wrapped around the junction of her torso and four-legged underbody, then arms wrapped around her shoulders from above. A cheetah muzzle appeared next to her muzzle and Iris moaned at the weight and size of the feline.

Iris's long, fluffy white tail was pinned to the side, leaving her rump exposed. The wolftaur's eyes bulged as she felt Ellynn's maleness prod forward. It was thicker than either of her own individually and slightly longer as well, and from the stiffness and warmth, the cheetah was clearly excited. There was no talking, only grunting and heavy breathing as Iris's hind legs stretched. Ellynn's fingers dug into the wolftaur's pelt, stroking down her shoulders and chest as she squirmed her lower body forward. She wanted this.

The wolftaur's muzzle opened and her eyes squeezed shut. Her twin erections throbbed inside the mount as she felt her aching, virginal pussy stretch open for the feline's arousal. Ellynn worked slowly, almost too slow, leaving the wolftaur twisting and squirming, dancing on her hind legs as the cheetahtaur confidently found her way inside.

“Nnnggghhhh!"

The sudden, intense pleasure of the feminine orgasm made Iris's whole body tense up. A shock of pleasure hit her as she clamped around the invading cheetahtaur shaft, and her entire body shifted suddenly backwards. Ellynn's purring moan filled the room next as the wolftaur engulfed the remaining length of cheetaur cock. Iris grunted, eyes flashing open, as Ellynn instinctively lurched forward, which ground both of the wolftaur's thick arousals down to the bases inside the breeding mount. The motorized internals clutched and clamped, grinding the two huge knots together.

A long, desperate howl rang out as Iris twisted her upper torso back into Ellynn's chest. Her arousals fired, adding to the intensity of the ongoing mess behind her taut, heavy balls. The overwhelming pleasure made Iris's ears flatten as she howled again, unable to stop as the machine pushed her orgasm into a whole other level of intensity. And the feeling of the cheetaur on top of her, filling her, stroking inside her so deep, making her insides quiver until…

Ellynn's claws snagged at the wolftaur's white-furred shoulders. Her chest pushed into Iris's back and her arms slid down, groping at the heavy white orbs bouncing on the other side. Ellynn's legs thrust now, firm and deep, and her whole body shook as she felt Iris squirming beneath her. As the wolf's howls rang in her ears, Ellynn's muzzle tipped back and her long hair draped down her backside.

“Ahhhh!"

She hadn't meant to cum so soon, but there was no helping it. The cheetahtaur's huge length swelled as the cannon fired, flooding the wolftaur with an enormous load of feline seed. The yellow forepaws clutched at the wolftaur's belly as she squeezed in tight and close, hilting and holding as her length pumped and flexed all on its own.

“Mmmmhhhh!"

Ellynn's fingers lifted, then tangled into the bright red mohawk-like strip of hair on Iris's head. The cheetaur pulled lightly and turned the wolftaur's head as she leaned around and over. The narrow lupine muzzle locked onto the broad cheetah lips at an angle, and soon their tongues met between their sharp teeth. Iris groaned and sagged, relaxing as she felt the afterglow approaching, even as Ellynn's hind legs bent and stretched again, working her massive length inside. A mess of seed drizzled back out and down the wolftaur's flanks, wetting her white fur to the skin beneath.

Iris's tail flicked weakly against her side as she luxuriated in the sensation of being filled so well. Her eyes closed as the machine slowed down to a light pulsing as her twins continued to leak. Her balls, still aching, apparently had a lot left to give before she'd feel fully satisfied.

As if sensing what Iris was thinking, Ellynn's muzzle pursed and kissed her on the cheek.

“Wanna trade places?" the cheetahtaur purred. “Though if we keep this up we'll have to get more barrels…"

* * *

Several months later…

“Iris! Coming your way!"

A bright pink frisbee flew across the green grass at the park. Ellynn watched it go, speeding off horizontally towards the other side of the clearing. The size of several football fields, it was surrounded by trees and walking paths. Others were using it as well - picnics, games of soccer, and other activities.

The ground trembled as a tall, muscular white-furred wolftaur thudded across the grass. Her black claws dug into the dirt as her long white tail flowed behind her. A tight spaghetti-strap top clung to her four heavy breasts, which flopped and bounced with the running strides of her underbody. The pale green fabric squeezed around each plump orb, but the waist of the shirt ended just below the bottom pair, leaving the additional four nipples spaced evenly below, two by two, just poking from the fur above the junction of her upper and lower bodies. The wolftaur's bright red mohawk waved from the wind around her as she leaped off the ground and stretched out her arms.

Able to jump quite high thanks to her powerful taur body, the wolf's hind legs stretched out behind her with her tail as she soared towards the flying disk. Between her flanks, an enormous white-furred sheath bounced and jiggled, wiggling side to side between her legs rapidly as a huge pair of lushly furred balls danced behind.

Iris landed with the toy clutched in her fingers. Her four large paws dug into the grass as she skidded to a halt, then quickly turned and took a few steps before throwing the frisbee back.

“Nice catch!" Ellynn called out before dashing to where the frisbee would land. The speedy feline didn't need to bother jumping - she was quick enough to simply run ahead of the throw and get to where it was going first.

The cheetah's bikini top dug into the fur around her shoulders as the heavy breasts filled the triangular cups. The straps were straight and taut as the overly small swimwear barely covered the plump nipples on the cheetaur's impressive pair. Like Iris, she wasn't wearing anything underneath, and her thick feline sheath and sac hung nicely between her flanks, though unlike Iris, the cheetaur sported half a foot of wood.

The wolftaur noticed right away, of course, and both of her huge lengths immediately sprung forth.

Trotting up after the last catch, Iris grinned at Ellynn.

“What do you think? Wanna go have a different kind of fun?" Iris asked. She was panting hard, which made her chest wobble even more.

Ellynn growled deep in her throat, and another foot of cheetaur cock drooped out of her thick white sheath. She nodded, then grinned as she lined up next to Iris and hooked her arm around the wolftaur's elbow.

“Sounds good!"

The two big taurs walked out of the park side by side, belly and rumps bumping. The cheetaur's enormous erection swayed above the ground, accompanied by both of the heavily knotted thicknesses swinging from between the wolftaur's flanks, which drew all sorts of attention, stares, and even surreptitious photos. Neither taur seemed to mind as they talked and giggled their way home - after all, it wasn't like they could just throw on a pair of jeans or something, right?

“Oh, look at that!" Ellynn said, holding up her phone. “It finally arrived!"

“It?" Iris asked.

The cheetaur's muzzle curled into a big, knowing smirk and her pale brown eyes narrowed.

“A new toy I know you're gonna love…"

The end
