Keys jingled in the lock, scratching and missing the mark. Several expletives followed in sequence with every attempt until the door finally burst open, a padded foot jutting mid-air.
“Hah. First try,” the orange-furred bobcat said with inflated bravado. He sauntered in with a cardboard box in his arms, his crimson tie swaying back and forth behind it. He was clad in all white, an open blazer revealing a creamy furred chest with loose slacks swaying around his ankles.
The bobcat’s flat was sparsely decorated. A typical living room with a decade-old couch, an old CRT TV that would have been rejected by a secondhand store, and a coat hanger near the front. The box he carried dropped onto the cocktail table that sat between the sofa and TV, the feline’s blocky muzzle breaking out into a toothy grin.
“Well-well, I wonder what we have here,” he purred to himself as he caught a nail underneath the haphazardly taped seal, cutting through it.  “I’m sure the resident egg-head won’t mind me ‘holding on’ to his package for him~”
Bubsy’s tufted tail wiggled left and right as he leaned forward, practically dunking his head into the liberated contents of its cardboard prison. “Oohhh!” he chimed, pulling out a six-pack of cans strung together by plastic rings. “I didn’t know the good doctor was a boozer~” He snickered to himself as he examined the innocuous cans. “Guess that’s another wino to add to the guys that I know.”
He pulled one of the cans from the rings, rolling it around in his padded palm. “I’m sure he won’t mind if I give it a little taste-test.” That’s when he caught sight of the logo, a silhouette of a massive figure flexing, biceps pushing higher than their own fists. “...BruteBrew?” He cocked his head to one side, a one-note laugh popping out of him. “What, do I need to break out the ManlyMug to drink this?” The can spun, aluminum flashing in the light from the picture window. “...A product of Biomass Industries,” he muttered, reading.
His grin somehow widened, nearly engulfing the bottom half of his face. “I guess you could say that their business is really…growing?” He stood there, basking in the applause and laughter of a non-existent audience. The tab of the can cracked with a soft hiss, the bobcat bringing the open end to his nose, giving it a few sniffs.
“Eugh. Smells like a guy’s pits.” His big, tufted ears twitched back, the insides warming up. “...That’s kinda hot? Am I seriously getting turned on by a MacGuffin in a can?” A full-body shiver traveled through the orange-furred feline. He closed his eyes, shaking his head as he worked through the stages of grief for his feelings. Tipping it back, he gave a few gulps.
Bubsy nearly gagged, but he kept going, screwing his eyes shut as his Adam’s apple jumped. He gasped after he was finished, panting as if he had just finished running a marathon. “Eugh! That was nasty! Forget what I said about beer being attractive.” He wiped at his lower lip, making overblown spitting motions, his tongue fluttering between his lips. “Would it kill them to add some grape flavoring?”
“Ough…” Bubsy’s stomach growled, churning and bubbling as he stroked gingerly over it. “Maybe…maybe that was a bad idea. What if I melt into a pile of sludge?” Fingers ran through his stylized mohawk, brushing it back. “I’m sure the doc can put me back together. He’s got…science gadgets for that sorta thing, right?” The tail end came out as a whine, a soft burp bubbling out of him, the bobcat leaning against his sofa for support.
“Mgg…” He clutched his midsection even as it undulated. A once-smooth surface began to ripple, divides forming as muscle began to surface, the outline of a six pack as proud as the cans that had come out of their box. “O-Oh… Haha… Abs to meet you too,” He huffed as the pink padding of his fingertips traced the cutting contours of those slowly swelling bricks. Veins webbed from his crotch, trailing up like branching roots.
Every breath seemed to add to his flat chest. Pectorals rose, like bumps at first, lifting the creamy tuft that dominated the space over his sternum. He pulled his hands up, feeling over the curve of those orbs as they lifted, pushing away from the cobbled abdominals below. A thumb flicking the vivid pink nipples underneath made him bite his lower lip as his eyes threatened to roll back in his skull.
“Pec-tacular,” he muttered as he squeezed those swelling mounds, striations lifting to the surface, subtly banding those growing boulders. “C’mon, baby~ Give me s’more,” he growled, leaning back to let his engorging chest breathe. The veins crawled up over those mounds, spreading over his shoulders, which coincidentally doubled in size. He grunted as his loose jacket suddenly started to grow more snug. Obliques crawled across his sides, rising as lats bloomed, spreading like wings into the insides of his blazer, stretching it around his sides.
“Urgh…” He groaned in ecstasy as his shoulders ballooned underneath the fabric, forcing it to warp around growing spheres. “Better move over Delt-a Air Lines, there’s a new bobcat about to take off…” He let go of his chest to get a better look at his arms. They lifted as he watched the once slack sleeves starting to shift, filling out as they pulled taut around thickening limbs. Biceps rounded out the inside of his sleeves, triceps taking on a bulging horseshoe-like shape that battled with his delts. Though the only one losing that war was his jacket. Forearms shredded, thickening into trunks that threatened to split his blazer open.
Bubsy grunted, his hands twitching, fingers flexing as veins crawled out from under his cuffs to branch over the back of his hands. Meat packed onto his paws, fingers thickening as his palms engorged, going from minor mittens to colossal clubs that could crush rock. He let out a low exhale as he examined them, spreading his digits, enjoying the cable-like tendons dancing to his command.
“Ech…!” Bubsy let out a choking sound as dense digits grabbed at his throat, biceps popping strangely sturdy seams as split mounds crashed into banding, warping pectorals. His tie pulled tight over his neck, the knot pressing down like a noose as his neck had tried to surge in size. Veins webbed around it like an innercity roadmap. A claw caught underneath the fabric, slipping between it and turgid flesh as he gave it a hard tug. It didn’t rip, but it did loosen—enough for that pillar to eagerly expand into the proffered space.
“Jeez, that one almost got me tongue tie-d!” a distinctly deeper voice rumbled, a bassy growl that thrummed from the steel cables of his fat neck. “Remind me knot to do that again.” Even with the tie loosened, it was already growing snug, pulling up around the base of that meaty tower.
Bubsy groaned as he felt the pressure mount under his slacks. He spread his stance as mass flowed downward, his ass going from 2x4 flat to bulging boulders wrapped in warped polyester. The front of his slacks bounced as his junk swelled, thickening to the point where it looked like he was trying to smuggle a grapefruit. A huge hand squeezed around it, lifting the obvious outlines of a thick anaconda.
“Ooohhh, that’s good… Not quite a third leg, but we’ll get to tripod status later,” he said with a giggle. Thighs rolled together as the pounds mounted, mass filling out his slacks to the brim as the outline of twitching quads surfaced. Behind him, hamstrings strummed like piano wire. Calves caught up quickly, the growing split shelf pulling the hem of his pants up over his ankles.
Panting, it finally seemed to be over. With his orange fur splitting out of several rips, his suit practically looked painted on. “This beats transforming into a furball. Guess they’ll have to call it meatball mode instead, heh,” he said before licking his lips. Bubsy reveled in his heavy gait, each footstep shuddering the floor and shaking his living room. The full body mirror he had kept in the corner of the room didn’t disappoint, the bobcat folding his arms behind his head, a toothy grin breaking out across his blunt, feline muzzle.
“Awyeah, that’s what I’m talkin’ about.” He clenched his thighs together, making his sizable junk pop out between them. “I bet the clap of these thunder thighs would make Thor jealous~” He rolled his abs in waves, sucking them into a vacuum only to push them back out into a beveled muscle gut only a second later.
“Man, if only I had an audience. Bet they’d love every second of this.” Swollen pectorals bounced, Bubsy testing out his control as he made them slowly roll, watching sinew band and bulge as dimples deepened. “...Or maybe a secret admirer.”
He paused, turning, his eyes sparkling.
“Or maybe…you.”
Bubsy’s grin widened as he stared directly at you, his bulging shoulders squaring, a hand on his hip. “What? You didn’t think I knew you were watching? Please.” Before you could react, a huge hand shot out, grabbing you by the shoulder and pulling you close to him. You had to crane your head back to be able to see past those jutting pectorals, the bobcat peeking behind them as he grinned like a maniac.
“Guess this is what they were talkin’ about with 4D, huh?” You opened your mouth to speak, but he immediately put a finger as big as your wrist to your lips. “Ap-bup-bup! No need to say anything,” he purred. “Just let your old pal Bubsy do all the talking.” You nodded meekly, but that seemed to be just what the big bobcat wanted.
“Good boy,” he whispered, leaning down, his pecs pushing into your face as his warm breath caressed your ear. His hand crept behind your head, gripping through your hair as those fat fingers clutched around your skull. “How about we add some smell-o-vision while we’re at it, huh?”
A groan bubbled out of you as he dragged your face between swollen pectorals, your nose brushing through the hirsute forest that covered them. His musk was heady—even more so when he lifted his arm, jacket peeling back just enough to reveal a russet bush practically bursting from under that bulging limb. You drank deeply of his unique aroma, earthy, tangy tones mingling with the salt from his sweat. Weirdly enough, there was a hint of cinnamon in there.
“Does my lil voyeur enjoy his pit-side voyage?” Your nodding was enough to satisfy, his fingers keeping a steady grip, making sure you couldn’t get fresh air. A pleasured growl bubbled out of him as your free hand slid over his chest, palm errantly pushing over a dense nipple that pointed straight down.
“You’re a real teatse, you know that?” You wanted to groan from the awful pun, but the squeeze of those powerful fingers around your head dashed the thought. Eventually, he allowed you to surface, your face slick, your eyes adjusting back to the light streaming in from the window.
“Man, you’re so small,” he said with a toothy smirk. “Or I’m just really fucking huge. Take your pick.” He seemed to be unable to let you go, a hand around your sides bringing you tight to him, the bobcat grinding the swelling erection that tented his slacks. You could see the slip of pink, the base of his endowment visible as his pants stretched beyond their limits. He wasn’t wearing anything underneath, not that modesty would matter now. You could see how those veins webbed from the base of his cock and into his lower stomach, branching up that cobbled wall of abdominals.
“Go on. Touch,” he encouraged, his hand caressing down your back and to your ass, those dense digits giving it a slow, salacious squeeze. “There’s enough bobcat for both of us.” Doing as he instructed, you stroked over his chest, tracing the grooves between those serrated bands. The tips of your fingers swirled around those nipples, eliciting a low groan from the cat as he leaned back. Cobbled abdominals were just as impressive, your fingers vanishing nearly to the second knuckle between those beveled bricks.
“Heh. Maybe I oughta call my agent and see if I can’t acquire that ‘touching is good’ slogan.” He grunted as your fingers lowered, brushing the vascularity that trailed down to his crotch. “Not like ‘The Big N.’ is using it.” Whatever Bubsy was thinking, it spilled from his brain as you squeezed his crotch, fingers slipping under the outline of his turgid sack. You didn’t get to do much more as you were suddenly pushed onto your back. A huge foot pressed over your chest with a sole just as wide as dense toes curled just under your chin.
“Heh. You look pretty adorable underfoot like that.” You couldn’t see his face from that angle, but you could practically hear the cracking of his toothy grin widening. “Toe-tally a good look for you.” You could see him flexing above you, given the perfect angle, past the foot pinning you in place. His thighs rolled, the rip along the inner seam growing larger as he made those mighty pillars shake, jiggle, then solidify. A whine bubbled out from you as you watched him flex those abs. His bulging arms folded behind his head, the edges of his too-small jacket lifting up as he sucked his stomach in, creating a deep crater of sinew.
“Awyeah, Bubsy’s back, baby! Bigger than ever! Can’t fit this in an expansion pack!” He huffed to himself, a prideful growl thrumming from his burly chest as he brought his arms up. He flexed hard, fists clenching. You watched as the insides of his sleeves split open, patchy threads clinging to swelling, split bicep heads. They fought for space, slamming against fat forearms as those peaks crawled up, threatening to brush Bubsy’s curled thumbs. The length that was caught in his slacks slithered down a thigh, rips showing the fleshy tones of that pulsating anaconda.
You opened your mouth to speak again, but his foot shoved forward. Bubsy smothered your face under the plush padding of that expansive sole, his thick toes curling around your head. “Now what did I say about letting me do the talking?~ There’s only room for one chatterbox here, and that’s me.” A shiver crawled up your spine, his voice dipping deep as he spoke, bordering on brutish as he breathed.
The foot came off of you, but a reprieve didn’t follow. Bubsy hauled you up as if you weighed nothing, using just one arm as he gripped the back of your shirt. Your head spun as you were whirled around him, brought up behind, those bulbous glutes going right to your face. You could see the deep divide between those cheeks. The meaty mounds deformed, bending around the clench of the slack’s waistband. Still, it didn’t stop a quarter of that orange-furred expanse from pushing out, lighter, creamier tones painting the divide between them. Bubsy’s tufted tail sat over them like a cherry on a cake, twitching left and right, the tip brushing the swollen curves of his burly back.
“Welcome to Bubsy’s bakery,” he said with a teasing growl in his throat. “I insist you try a sample~”
You barely had time to gulp one last breath of fresh air before being driven down underneath his tail. He ground you deep, those glutes rolling, audibly clapping together as they pinched your muzzle between them, squeezing and salaciously pulling. Your flailing hands found the edges of those giant glutes, your palms sinking into the deep dimple that formed when they warped from boulders to banded croissants.
Even with his ass clenching around your skull, you couldn’t help but let your hands wander. They traced up the taut pillars of muscle that comprised his lower back, moving on to the rolling hills and valleys that spread beyond. It was a frustration that his clothes still hung on him, his overstretched jacket stymying your efforts to go farther. You had no idea what cartoon logic was holding these garments together, only that it was starting to run threadbare.
Bubsy laughed as if he had heard the unintended pun, his booming voice shaking through the relatively small room. “C’mon, kid. Go a little lower,” He purred, his fingers barely able to reach you thanks to his engorged size, the tips of those bulky digits brushing your shoulder. Lowering yourself down to your knees, you hugged one of those enormous thighs. They were bigger than your chest, a mighty pillar of muscle that twitched and rolled with even the slightest movement. You could only imagine what Bubsy could do now; a single kick could probably knock one of those walls down.
The big cat’s calf tented out the cuffs of his slacks, pulling them up high above his ankles. The split between those warring heads was enough to nearly sink your finger between, the feline lifting himself onto his toes just to make those mounds swell and clench.
“Sorry, couldn’t settle for the whole cow,” he said with a low chuckle. 
When you didn’t immediately respond, he added, “Y’know… Because ‘calf’ muscle? Geddit?” There was an awkward pause that trailed, the big bobcat clearing his throat. “Whatever.” You went to respond, to sputter something indignantly, but Bubsy caught you before you could get the first words out.
“Alright, I see I need to occupy that mouth with something,” he said, his voice low, almost dangerous. Bubsy seized your chin, coiling fingers under it as he made you look up at him from on your knees. A thumb pushed against your lips, sliding along from side to side before the tip pushed in. A moan slipped past, but not before his thumb could effectively cork it. Bubsy chuckled to himself as he rolled the tip of his salt-tanged digit against your lapping tongue.
“That’s better,” he said, eyes lidding as he pushed more of that thick finger into your muzzle, forcing you to mouth over it. “Heh. Got me all frazzled here, kid. Can’t think of anything witty…” he muttered distractedly, and you could see why. A damp spot was already starting to form down his inner thigh, his shaft fighting with the confines of his pants. With a deft few movements, the bobcat managed to free himself, his pre-cum slicked shaft flopping out into the air, twitching into over a foot of meaty manhood.
He pushed his thumb deep, playfully wrestling with your tongue as his other fingers curled under your chin, scratching it encouragingly. “That’s good. You ready for the main meal? Of course you are.” His thumb pulled from your mouth with a pop, only to be replaced by the helmeted head as it nudged under your nose. “Go on…” he said, his voice low and seductive as he rolled his hips. His glans pushed past your lips as you opened your mouth wide. You weren’t sure which moan was louder in your ears, your own or Bubsy’s as his length dipped into you. He was tangy, earthy musk mixing with a bit of sweat and a lot of precum.
“Fuck,” he said in a breathy huff as he stepped forward. He gripped behind your head with both hands, pushing you forward to swallow more of his length. It dove down your throat as he thrust slowly, his enormous body trembling with the attempt to hold himself back. “What a mouth on you… Not good for chatter, but damn if it ain’t mind blowing,” he finished with a shaky chuckle. He let out a few throaty sounds, rolling his head back as his toes curled. He thrust slowly, working himself in and out of you. It wasn’t long until the fuzzy bush above his crotch pushed into your nose, giving you another deep whiff of his cinnamon-tinged fragrance.
Shakily, he grabbed your hand, bringing it up so you cupped his swollen sack. You heard a long, groaning “Oh, yeah…” as you did that, rolling those twin grapefruits around. “Bet none of those other mascot wannabees would treat you like this, huh? Fanservice is so—nghh—rare these days…”
You could barely focus on his incessant chattering. It took just about everything to keep from choking on that lengthy endowment as you were forced all the way to the base. You locked arms around his hips, holding onto the small of his back, your hand brushing Bubsy’s tufted tail as it flicked excitedly. This went on for minutes, time losing meaning as you focused on the rhythm of his thrusts, his heavy weight causing the floorboards to creak every time he swung his hips as thick thighs pistoned.
“Hooo, alright. Don’t wanna wrap up this special episode just quite yet,” he said with a breathless laugh, pulling you from his cock with a wet pop. Strings of saliva stretched between your lips and that swollen head before snapping.
“Want to see a party trick?” he asked, flashing you a little smirk, one barely visible from around the rising crest of those orange-furred pecs. You saw what was dangling from the tips of his fingers before you could give him a proper answer. It was the rest of those cans of growth-inducing formula.
Thoughts raced through your mind of what he would be like several times this size, and it was simultaneously salacious, yet terrifying. You didn’t have long to linger as he put half of those cans between his pecs, tearing the plastic rings. Muscle banded as he brought his shoulders forward, pecs clenching around aluminum as the cans warped and hissed. Bubsy opened his mouth, closing his eyes as the tops exploded open, the spray gushing unerringly into his open maw. He gulped, Adam’s apple bobbing.
The rest of the cans went between his biceps and his forearm, taking them one at a time as he burst them open into his mouth. Bubsy’s stomach grumbled and growled, bricks of muscle growing swollen. Sweat beaded over his forehead as he chuckled, tossing the remains of the cans aside, letting them roll. “Hoohoo, yeah… This is gonna be good,” he said with a low moan as he clutched at his stomach.
The results were immediate and explosive. As Bubsy hunched over, his back detonated, tearing a rip down the middle of his blazer. Swollen sinew pushing through the fabric was like watching a butterfly emerge from a chrysalis as absurd size packed into the bulging bobcat. The walls shuddered with booming grunts as Bubsy hunched further, his arms flipping forward as they flexed. The rest of his blazer disintegrated, tearing into shreds that fluttered to the floor. Traps rose high enough to compete with the base of the bobcat’s big ears. Biceps slammed into pecs, forcing his elbows out even wider as the bloated mounds battled.
Varicose veins writhed across those arms, his delts ballooning and rippling, practically folding on themselves as deep divides split those boulders several times over. Bubsy’s eyes glazed over with pure ecstasy, tongue hanging out even as his pecs humped up to consume his face. Lats widened into overgrown wings, lowering to the point where they threatened to graze his twin boulders for glutes. His thighs pumped, destroying the rest of his slacks, the fabric falling in a halo around him. Muscle stood on end, finely shredded and overpacked to the point where it made his hide audibly creak around it.
“Fuck,” he boomed, breathing heavy, those massive pectorals bobbing. His neck fattened to the point where it no longer cared for the tie clinging to it. Like a squeezed sausage, it nearly bisected as it bulged before the crimson fabric snapped like a rubber band. The length fluttered to the floor, joining the rest of the wrecked outfit. He let out a long sigh of pleasure, his eyes rolling back in his head as swollen veins crawled up that pillar. With a few loud pops, his jawline thickened. It grew blocky, his chin jutting forward as it clefted, crashing into the rising curvature of his heaving pectoral shelf. A dark shadow encompassed the lower half of his bell-bottomed skull in a scratchy, permanent 5 o’clock stubble. The striations could be seen along the edges of that jawline, where muscle rippled and rose, testosterone-overloaded meat filling the contours and comprising the rising curvatures and ridges of his now-masculine mug.
The floor threatened to crack, visibly bowing under the immense weight it was forced to bear. Toes curled, tendons thrumming as calves bulged, fighting for relevance under the shadow of monstrously quads. And he just kept widening. Mass piled onto him, causing him to stretch in nearly every direction but up. You were starting to feel incredibly small, bordering on irrelevance, as you were forced to scoot back on your ass. The sofa squeaked, pushed aside with just a single, earth-tilting step. The TV wobbled before falling from its stand, not that Bubsy seemed to mind. He was far too busy, panting like a beast as he cupped those monstrous pectorals—so large that they arched up and over his line of sight from their own heft.
That wasn’t even your biggest worry. The cock that had once (barely) fit down your throat was now barreling towards you as big as a log. The pre-slicked meat dropped over your chest, weighing you down to the floor as the behemoth bobcat rocked his hips. Swollen balls brushed between knees, then rolled between calves before ultimately dropping and spreading across the floor. “OOohhh…YEAH!” he roared, his once high-pitched chatter having been reduced to a block-shaking boom.
“Haha… DLC? You’re gonna need both season passes to fit this bobcat!” With a thunderous grunt, he hefted both arms up, clenching powerful paws into curled fists. Biceps immediately activated, splitting once, twice, then again. Where they once teased his thumb, they now shoved it out of the way with the arrogance they deserved. Peaks pushed well past his knuckles, engorging to the size where you had to question what was bigger: a medicine ball, or those vein-wrapped boulders?
It wasn’t a quandary you could entertain for long. Not with that enormous endowment grinding you into the carpet. The weight was immense, every thrum of that pounding heart making it jump, then drop down like an anvil of flesh over you. The pleasured noises that churned up from him when you wrapped your limbs around that enormous endowment shook you to the core. It was like the cross between a beast in heat and the growl of an industrial engine as the windows quivered. It was a wonder you didn’t go deaf. Or get crushed by just the enormity of the oozing shaft slipping between your loose grip.
Either way, things were reaching a climax. The heat from his body caused rolling dollops of sweat to vaporize before they could even drip to the floor. The windows fogged, a muggy, musky atmosphere hazing the room as your head went light. You couldn’t see much from your position on the floor, but you could see Bubsy shamelessly worshipping himself—seemingly the only thing that shut up the big cat as he grunted. His lower lip had fattened up, flesh darkened and pressed eagerly against one of those bloated biceps. A barbed tongue unfurled, tracing the inches-deep split, unabashedly slathering.
The deep grunts grew more desperate, the rock of his hips growing erratic. The carpet had torn up from where his feet dug in, revealing crushed floorboards underneath those absurdly wide soles. “Haaaa…” he breathed, dropping his arms—limbs that were so huge they hung at nearly 90-degree angles from his sides. He was a behemoth of a man, wider than he was tall—nearly in depth as well. He tilted forward, those enormous pecs pressing against his cock, wrapping around the end as he bucked into his own cleavage. Hands shot out, plaster cracking and cratering as he braced on opposing walls for the finale.
Bubsy bellowed as he threw his head back, skull slamming into mountainous traps, “I got your action platforming right…nggh!…HERE!”
His urethra swelled like someone diverted a river through it. It pressed you flat to the floor, flesh rolling over you like dough even as the first ropes blasted. You could hear the sound of shattering glass as Bubsy’s cum canon destroyed the window—and the rest of the wall alongside it. Turgid balls had humped up behind him, pressing against his ass and lower back as they undulated and pulsated. They visibly clenched, warping and denting inward as they yanked and pulled between spreading thighs.
His orgasm lasted for minutes. It was during that time that you realized that his destruction of property was a good thing. With as much as he was pumping, there was no doubt in your mind you would have drowned under the feline’s flooding jism. With a wet slap that finally dropped you to the floor, his intense orgasm finally petered off. Bubsy panted heavily, sucking in air in greedy gulps. Sweat rolled in rivulets, tracing the sinuous expanse of sinew that filled a good half of the room.
After a moment, he finally chuckled deeply. “Now if that performance doesn’t win me a Golden X Award, I don’t know what else will…” It was only when his cock twitched that he realized that you were underneath him. “Heh. Don’t go passin’ out on me yet, lil buddy~ Your ol’ pal’s got a plan, and it ain’t stoppin’ here,” he cooed—which is to say, he boomed with the force of an encroaching thunderstorm.
You could only imagine how far this could go. How many more puns and jokes could he continue to churn out even as he doubles and triples in muscle mass?
It was enough to make your head spin.
“Hey, at least your head can spin,” Bubsy said with a low snicker. “You aren’t working with tank controls~” He emphasized his point with a roll of those titanic shoulders.
You simultaneously wanted to die and throw yourself at him. It was a confusing combination of emotions that left your feline captor’s explosive laughter echoing in your ears.
