* * *

Ever since the "incident," Maloo's favorite thing was pumping iron. At nearly twelve feet tall and hundreds and hundreds of pounds, the massive cougar put any other lifters to shame whenever shi showed up. Shi could curl hundreds of pounds with one paw, all while carting around the largest breasts and the biggest package anyone had ever seen.

The cougar made an entrance even when she didn't intend to. Today, for instance, when shi decided to head to hir favorite gym for a good workout.

The floor shook ominously as a massive figure passed by the street-facing windows, darkening the inside of the gym. The glass double-doors swung open and a massive, bulging pair of shorts squeezed through, filling the entranceway. The desk attendant shrunk back as two enormous legs followed, each as thick around as a mighty oak. Golden fur shimmered in the light as a head leaned down, just managing to squeeze in through the doorway, accompanied by breasts that wobbled and jiggled uncontrollably with every movement.

The cougar's shirt was blue and wrapped tightly around hir chest, shoulders, and backside. Huge nipples distended the writing on the front - one word, "Warning," in red, and, underneath, three giant white letters: "E.C.F." Once the arduous task of making it inside was complete, Maloo straightened up and smiled at the attendant.

"Hey... can I get a towel?"

Wordlessly, the attendant passed the huge cougar a towel, which was much, much too tiny for hir, but shi still tossed it over hir shoulder and strode into the gym proper, a duffel bag, clutched in hir paw.

A few people fell off their treadmills when, upon sight of hir, they realized their legs no longer functioned. Maloo smiled at them apologetically as shi made hir way carefully to the back of the gym where the free weights sat. A few other people were working out, but soon cleared the section to give hir space.

Maloo tossed hir duffel down and bent over to open it up. The cougar's massive glutes flexed mightily as shi inadvertently aimed the thick rump right at the majority of the patrons, briefly stopping the heart of one. A powerful tail, thick around as an average person's hips, swung back and forth behind hir. Despite its strength, it remained the fluffiest part about hir.

The huge cougar pulled a water bottle out of hir large duffel. Well, more like a water barrel, since the bright blue container had an impromptu handle attached to what was otherwise something usually only seen in warehouses and used to store chemicals. This one, however, was brand new, a good way for the cougar to rehydrate without running up the gym's water bills.

Shi set the barrel down next to hir and reached for a long metal bar, upon which shi piled every weight shi could spot. Shi noticed out of the corner of hir eye a few people watching and smiled. Shi didn't mind a crowd; in fact, though shi had perfectly good equipment at home, the truth was Maloo was a bit of a showoff. If you got it, shi figured, why not flaunt it?

Hir massive bicep swelled up fantastically on each rep, pushing hir huge breasts to the side as it grew and deflated with each mighty curl. Shi kept hir eyes on the crowd as shi worked out. Maybe shi'd find someone to take home later...

Shi didn't notice, however, one person who snuck around behind hir and dropped something into the water barrel. The tall, muscular wolf-naga, with thick black fur and a wolf's body from the hips up, with a long, long snake body in place of legs, slipped around the barrel, coiling once, before slithering around in front of the cougar. Shadohime smiled, lips parting to reveal sharp white fangs. A white shirt hung around hir chest, covering hir prodigious breasts and slim belly, while a loincloth-like apparatus kept hir midsection modest in the absence of the ability to wear pants.

Maloo grinned down at the wolf-naga casually and nodded. "Hey there."

"Hey, yourself! I've seen you around here before," the hybrid said. "Maloo, right?"

Maloo's grin grew wider. "S'right! How's it going?" As shi spoke, shi switched the bar - normally one used with both hands - to the other paw and pumped it up and down rhythmically, making hir right breast bounce off hir bicep.

"Doing good. Geez, how'd you get so big, anyways?" Shadohime asked. "I mean, not to pry, but... damn!"

Maloo's deep chuckle echoed through the gym. "Oh, this and that, you know." Someone caught hir eye - one of the gym's employees, a new trainer. "Oh, hey, Boo!"

A tall rabbit stood and turned, waving towards Maloo. Shi spoke a few words to the person on a treadmill - hir client, most likely - and then walked over to join the cougar and wolf-naga. "Hey, Maloo. Saw you come in and get right to work, as usual. Had a client or I would have said hello sooner!"

The cougar smiled broadly. "No problem." Shi dropped the bar to the floor and reached for hir water barrel, lifting it up and chugging a few gallons before smacking hir lips and setting it back down. Shadohime smiled.

"Boo, do you know Shadohime?" Maloo asked. "Shi was just introducing hirself."

"Oh, nice to meet you," the wolf-naga said, extending an arm to the tall, well-endowed rabbit. Shadohime's gaze flickered up and down the large lapine, taking in hir cute face, tall ears, heavy breasts, and meaty package, all of it wrapped up in a pair of taut shorts and a sports bra that was probably at least one size too small.

Pleasantries exchanged, Maloo continued pumping iron as they chatted about the usual topics. Maloo's attention was divided, however, between the attractive herms and hir workout, which felt different than usual. The twelve-foot-tall beast switched to the bench press and laid back, legs planted on the floor, massive package spilling across the bench. Hir powerful arms squeezed hir breasts together as shi lifted the bar above hir breasts. Every weight in the house was currently bolted onto the bar, but after just a few reps, Maloo paused.

"Hey, do you two mind helping me out for a bit?" shi asked. "Just hang on to the ends there..."

Bemused, Shadohime and Boo did as asked, each taking a firm grip on either end of the bench press. Both were surprised when the cougar's arms pushed up, straining with the effort, and lifted them clear off the floor. Well, most of Shadohime was lifted off the floor, but plenty of hir long lower body remained coiled up beneath hir.

Maloo grunted, inhaling deeply, arms burning, as shi felt a tingle in hir veins. Hir fur stood on end as shi pushed up again and again, pumping the bar over and over. Shi gasped as hir belly contracted and opened hir eyes wide as hir arms bulked up even further, visibly growing.

"Uh... Maloo?" Boo asked, still gamely clinging to the bar. Every time shi was lifted upwards, hir chest and midsection dragged across the side of the massive cougar's chest - a not unpleasant experience.

Shadohime affected a concerned disposition as well as shi felt the giant cougar's chest expanding against hir body as well. "Wow, what's happening? I have no idea! Do you? 'Cuz I don't!" shi said completely innocently.

Maloo huffed as shi kept pumping the iron. It felt good. Really good. Every rep was better than the last, and easier, too. Shi didn't really notice that shi was growing until the weight bench, finally overcome, flattened beneath hir, dropping hir onto the floor and cracking the cement. Hir huge package stretched out hir shorts even further, filling out like a balloon, keeping hir sheath and nuts compacted together. The cougar didn't stop pumping the bar, however, pulling it down against hir expanding breasts. Hir biceps flexed, hir triceps strained, and hir thighs thickened, growing larger and larger by the moment.

"Maloo? Hey, Maloo!" Boo shouted, kicking hir legs as shi was lifted higher and higher into the air. Shadohime grinned uncontrollably as the growth elixir activated, triggering off the lactic acid produced by the feline's incredible bulk.

Maloo moaned as hir shirt tightened, tearing around the neck. Hir shorts frayed and the button popped off, flying so fast it put a hole in the ceiling. Other gym patrons began to file out as attendants herded them away from the machines, saying there was an error with the ECF system and that until it was over, the building wasn't safe.

Boo's eyes went wide as shi watched, awestruck by the cougar's size. Fully aroused thanks to the endless grinding against the side of the cougar's enormous chest, the rabbit couldn't hardly believe what shi was seeing. The cougar was thicker, taller, and more muscular than ever before, almost fourteen feet tall. Shi probably wouldn't be able to stand without hir head hitting the ceiling. And the wolf-naga on the other side was enjoying hirself far too much for this to be a coincidence...

"What did you do?" shi called out to Shadohime. "Don't you know you shouldn't mess with ECFs? It's too unpredictable!"

The wolf-naga laughed as shi reached out, pressing a paw into the side of the cougar's incredibly huge - and growing - package. Hir hand sunk in, disappearing into the fabric. "Nonsense! It's just a little growth serum I cooked up. It's harmless!"

Boo shook hir head as shi heard the weight bar drop. A massive paw wrapped around hir backside, nearly completely around hir hips. "No, you fool! No! Shi's gonna blow!"

A second paw grabbed at Shadohime as a low rumble of pleasure shook the whole room, empty now but for the three of them. Maloo sat up, groaning deeply. Hir huge breasts squeezed against hir package, completely obscuring the view of hir midsection, as two enormous nipples ripped through the "Warning: ECF" shirt, bursting free to grow even larger faster. Hir package kept pace, and within a few more moments, the cougar's incredibly huge golden-furred sheath spilled out, complete with balls as big as tractor tires. Shadohime and Boo found themselves pressed against the sides of the thick tube as the nearly four-foot-thick shaft pulsed warningly. A black tip as wide across as a dinner table pressed free of the golden cuff at the top of the sheath, then spilled out en masse, flopping over the large balls and down to the floor beyond. Maloo's hips swelled, rump thickening, as shi let out a groan of delight.

"Biiiiiiggggeerrrrrrr..."

The ominous rumble made even Shadohime nervous. The wolf-naga had to admit shi may have miscalculated the potency of hir growth serum as shi found hirself pressing hir chest up against the thick black stalk. The veins shi caressed were almost as thick as hir arms. Coiling around the base, Shadohime grinned as shi squeezed down tightly, making the ECF shudder. Too late to turn back now, so may as well enjoy it, shi thought.

Boo, on the other hand, found hirself somewhere in the cougar's cleavage, swimming in an ocean of warm pelt and smooth nipples. Maloo's musky scent flooded hir nose as shi reached out, paws grasping at one of the giant nipples, hauling hirself up over the massive breast. Maloo was rapidly approaching twenty feet, well on hir way there. The cougar's huge tail swept gym equipment out of the way as though it weighed nothing, leaving space for hir to lean back against the wall, which cracked against hir shoulders.

The huge cougar gasped as shi felt hir shaft tremble. The meaty, rubbery, warm flesh throbbed, lifting upwards. Each throb gave it new length, strength, and girth; combined with hir massive nuts pushing it upwards, it soon bumped against the ceiling. Each throb made the length lower, then rise rapidly, thwacking against the roof and putting dents in the drywall. Boo stared in amazement, more aroused than shi could ever remember. Shi was no small fry hirself at seven feet tall, but this... this was ridiculous. The cougar was well over twice hir height and still growing, filling the more and more of the gym floor with incredibly muscular legs, arms, and shoulders.

A massive golden paw reached down and squeezed Boo, pressing hir against one of the cougar's huge nipples. Boo shuddered as shi felt hir shorts strain around hir erection. The rabbit's nearly two-foot-long cock was a toothpick compared to the cougar's reality-bending six-foot-wide, sixteen-foot-long behemoth, but that didn't seem to bother Maloo. Hir fingers ran over Boo's figure, teasing and stroking hir, while hir other paw did the same to Shadohime. The wolf-naga's coils wrapped around the cougar's sheath, squeezing and stroking. Shi'd lost hir top along the way, allowing hir large, firm breasts to press against the warm cockflesh. Hir own erection tented hir loincloth dramatically, revealing its size and girth. Like Boo, though, shi paled to the enormously growing feline beneath them.

"Moooooooorrrrrreeee..."

Maloo's passionate rumbles made the whole building shake as shi kept growing. The water barrel was squashed beneath hir as shi reached out and grasped hir erection. Before, hir package had been roughly the same size as hir breasts when they were all bundled up. Now, however, hir cock had grown faster, so that it was roughly twice as big as hir breasts. Each huge nut was nearly sixteen feet across and flattened against the floor. They audibly rumbled and creaked as the cougar wrestled hir cock back against hir chest, between hir breasts. The tip reached past hir head, pushing against the wall. Boo narrowly managed to avoid being pinned between the long ebon length and the nipple shi was desperately clinging to. Shadohime, still wrapped around the base, grinned at hir as shi passed by.

Large golden-furred paws stroked the length, rapidly massaging the incredible meat. Outside, people stared in through the windows, mostly shocked, some appalled, others uncontrollably aroused by the sight and smell of the ECF inside. Maloo ignored it all as lust swept through hir. Shi'd never been so big... so horny... the urge to cum welled up inside hir like a bolt of lightning and shi clutched at hir cock in both paws, arms flexing around the massive thing as it grew and thickened further, until it was nearly as wide around as shi was. It spread hir breasts, causing them to wobble; Boo hung on gamely as the golden pelt tickled hir erection. Shi panted and moaned, unable to stop the feelings bubbling up inside hir as the cougar's musky scent tipped hir over the edge from "worried about getting smooshed beneath Maloo" to "get off by any means necessary right now oh God so horny".

Shadohime was already there. The wolf-naga's hands pressed into the titanic flesh, stroking and rubbing as best as shi could, smearing some of the thick drops of pre-cum that rolled down the incredible length. The urethra bulged outwards, stretching the warm flesh, as the cougar's right foot went through the glass and into the street outside. Hir cock flexed, slapping up against the ceiling. Plaster rained down around them as it dropped back. The head hit the wall and went right through, into the bakery next door, dumping a load of warm pre-cum over the shocked proprietor and the plate of freshly glazed sticky buns she was serving.

The cougar's fingers dug into hir enormous stalk as the growth finally petered out. Shi was well over twenty feet, probably closer to double hir original twelve-foot size. Boo clutched at hir breast, feet digging into the cougar's belly, muzzle open so hir tongue could drag across the smooth flesh. Shadohime was similarly engaged with the cougar's sheath, tugging the flesh down to expose more of the sensitive base. Maloo shuddered and growled, moaning aloud, body trembling. Out in the street, hir toes wiggled back and forth.

Hir leg bent, pushing hir knee into the ceiling. The cougar's tail filled most of the rest of the available space, wrapping around hir massive nuts and squeezing them. They were big enough to reach floor-to-ceiling at this point and, squeezed from both sides, were visibly pulsing, dramatically full, ready to explode at a moment's notice. The cougar's muzzle hung open as shi licked up and down the top of hir stalk, both paws working the rest.

The noise of such a giant cock reaching orgasm was something neither Shadohime nor Boo had ever heard before, or could quite describe afterwards. It was like a mix of an train rolling along underwater with a motorcycle in need of a valve job muffled by a brick wall. The whole building shook again as the cougar's hips thrust, driving hir cock in and out of the hole in the wall to the bakery next door.

The roar that emanated from Maloo's muzzle shattered the rest of the windows in the front of the building. The first blast of cum put a new hole in the wall, though the later shots lacked quite as much power and merely splattered against the drywall and bricks, flooding the bakery and the gym proper with several feet of sticky white honey bun glazing.

Maloo's eyes squeezed shut as pleasure made hir tingle from hir rounded ears to hir spread toes. Hir balls shuddered as they cracked the ceiling and floor, and hir cock twitched, flopping back and forth like a fish against hir breasts. Cum poured over Shadohime and Boo, soaking them in moments. Shadohime's hips thrust against the cougar's cock, wet-humping the massive tool as shi went over the edge as well, adding a nice bit of change to the pile. Boo's soaked shorts ripped right off hir hips as shi let out a moan of carnal pleasure, sticky breasts sliding against the cougar's nipple, hips trembling as hir cock slid against Maloo's huge breast. Shi came hard, gasping and leaning back, paws grasping fur to hold hirself up. Maloo shuddered as shi felt the two warm bodies against hir, spurring hir orgasm on. A wave of cum flooded out of the doors of the two businesses, washing bicycles, newspaper boxes, and the occasional person down the street.

And still the ECF came, shooting great big huge jets of sizzling warm feline seed. It dripped from the ceiling, rolled out the doors and windows, got into the cracks of the pavement and poured down the sewers, threatening to cause a flash flood. The cougar's flexing shaft rocked in hir strong arms as shi struggled to control it, trying to grope and rub it at the same time. Shadohime's moans grew muffled as cum poured down the length, washing over hir head and body, soaking hir down like a firehose. Boo got just as much as shi found hir grip slipping, the fur too wet to hold onto. With a cry, the tall rabbit fell on Maloo's belly, rolled over... and watched the massive shaft descend towards hir, squeezing hir warmly into the wet fur until it wrung massive amounts of cum right out of the rabbit's fur. Boo moaned, still hard, cumming again and again as shi was swept away by the powerful scent and taste of Maloo's seed.

Shadohime, too, found hirself slipping, unable to get any purchase because of how sticky and slick everything was. Shi soon found hirself next to Boo, coils working through the thick cum, as the cougar's paws worked up and down, up and down, squeezing them between hir belly, breasts, and cock over and over. How long it lasted, neither could say, but eventually, they realized they weren't having quite as hard of a time as before. They could get their arms farther around Maloo's cock; they could push themselves up the two-and-a-half-story tall body with ease; Shadohime even managed to get hir coils back around the base of the cougar's shaft and pull hirself back around in front.

The reason for their ease, however, soon became apparent. As the enormous cougar fuckbeast continued to shower them with thick, hot seed, Boo looked down and saw shi was taller than before. Shi glared at Shadohime, who was happily discovering hir cock was expanding at a significantly increased rate. Noticing Boo's look, shi shrugged and wiped some cum from hir face as the cougar rumbled and moaned above them.

"Hey, I didn't think... mmmmmfff! That it was contagious!"

The end.
