Pumped
By Da Boz


Simba and Boz had arrived to their own private gym located in the heart of the city, close to where they lived. Neither enjoyed sharing workout rooms with others who might wander in to public gyms, so the lion, on a whim, had purchased their very own structure to convert into their own personal space to workout. There was something encouraging about having their own private space to pump iron, and they found themselves doing it more often than they would have at a small cramped space back at their domicile.

Once settled inside the weight lifting room, surrounded by the many bench presses, weight racks and other barbell machinery, Simba would set his duffle bag down. Soon he would remove the loose fitting nylon tank he wore, as well as his red shorts made of the same material. This would leave the muscular feline in only a snug pair of stretchy yellow spandex briefs, with a zebra stripe pattern.

Bozs emerald eyes were immediately drawn to his mates brawny physique, the green orbs tracing of the muscular ridges all over his golden body. within his own pair of gym shorts, shaft tucked away in a matching speedo twitched and thickened with arousal.

"You sure are looking big!" Boz commented to Simba, while the lion was stripping free of his gym shorts, down to his zebra stripe patterned yellow speedo.

The lion would flash a pearly white smile, tossing his head to the side to get a few stray strands of his glossy mane out of his eyes. "And we'll only get bigger..." Turning his head away as he lumbered over to the weight rack, he would utter quietly to himself "you especially."

Boz would remove his own pair of loose fitting nylon blue shorts, revealing his identical spandex brief suit to the lions. Eyes having followed Simba, and ear would twitch as he thought he'd heard something, and when the golden feline tromped back to him, twin weights in hand he would eye him curiously. "Did you say something else?"

Simba would shake his head, smiling knowingly, as he handed the two fifty pounders over to his tiger mate. "No, not at all, now get pumping, stud, I want to see those huge biceps bulging even more."

Boz took the offered weights with a grunt, muscular arms ridging as they strained to hold them at first. Grinning at the lion, he would sit himself down at a nearby bench, beginning some arm curls with the hefty weights, taking turns lifting each mighty arm.

"Mmm..." Simba would watch as Boz began his repetitions, moving back over to the metal weight rack and grabbing his own set of free weights. He would then lumber back over to where Boz was seated, taking the bench next to him, and beginning his own lifting routine.

As Simba approached, Boz would turn from watching the weights back to him, green eyes falling upon the lions huge guns that swelled even more each time he curled the fifty pounder towards his barrel chest. Immediately the tiger found himself even more intensely aroused, his spandex encased manhood stirring and twitching harder at the sight of those twin boulders bulging.

“Like what you see?” Simba inquired deeply, raising his tongue towards his upper teeth, giving one of the sharpest incisors a tantalizing lick. “Bet I already got you rock hard.”

Boz huffed, adjusting himself upon his bench as his manhood soon became uncomfortably hard. Quick to be enticed, and even faster to find himself sporting a huge bulge, the tiger would give his head a shake of denial. “Ur…no, I’m just getting more comfortable!” with a grunt, he’d continue to lift the dumbbells towards his chest, one after the other, trying to get his mind off of his now raging wood.

"Oooh yea, pump it, you sexy beast." Simba encouraged, a sly smile curling the right side of his muzzle as he watched Boz continue his weight lifting. He took further satisfaction in noting that the tiger didn't even appear to realize his once flat, muscle hewn abdominals were beginning to bulge outward, stomach swelling slightly. The same thing appeared to occur the the stripy felines arms and legs, gradually becoming thicker than before, but not in a way the tiger would notice...yet.

"I'm so turned on." Boz soon confessed, bringing his fifty pound barbell to his heaving chest once again, eyes still glued to his mates hulking body. He wasn’t sure why he was suddenly compelled to admit how excited he felt, so much so he still hadn’t notice the bit of an increase to his bodys girth.

"Oh? Getting more and more pumped are you?" Simba teased, bringing his weights upwards over his head, and raising them up and down this way as he might upon a bench press "Better be careful, or you might get too pumped..." He smirked.

Boz took a deep, hissingbreath as his eyes followed the lions arms while they lifted above his head, pumping his twin weights in this fashion. The already humungous globes that were his biceps bulged and swelled even more, beads of presperation appearing on the lions forehead as Boz watched. For a second his eyes would drop down to the lions crotch, only to find that his already noticeable package had thickened even more as well, a balloon like protrusion in the clingy Lycra spandex that his manhood was wrapped within.

"Oh...fuck..." Boz felt himself getting even harder, cock struggling against the slick slippery fabric of his yellow striped brief, and as he happened to glance downwards, his eyes would widen in surprise as he finally saw how much his gut was beginning to stick out. Though it didn't obscure his bulging speedo basket entirely, it was sticking out enough to be noticeable and cause the tiger alarm.

"My bellys growing!" Boz suddenly blurted out, dropping his weights to the floor. The moment they struck the hard surface they emitted a loud clanging noise, just as Boz had begun squeezing and prodding at his inflated midsection.

"You wanted to get pumped!" Simba laughed, weights still moving up and down to either side of his head "Silly hunky brute, you're going to blow up bigger and bigger the more I work out! Each rep will make you rounder and rounder!"

Boz simply gawked at Simba “W-what? You can’t be serious!” Saying this with exaggerated disbelief. There was however no way to disbelieve what his eyes saw, as his once flat abdominals became a thick roig-gut, expanding even more until the outlive of his abs began to vanish entirely.

“I’m very serious.” Simba chuckled, arms raising up and down, dumbbells in hand. “You always have such a macho swagger, like you’re the bigger of us two! Well…now you will be, just not in the way you thought!”

Boz, starting to panic, squeezed and pressed on his growing belly, as if trying to cease its sudden rapid inflation. This not only proved futile, but became difficult to even attempt as his arms and hands began to balloon up as well.

"Fuck...feels so damn GOOD to pump up so big and huge, muscles bulging bigger and bigger!" Simba grunts as he lifted the free weights, gritting his teeth and smiling as he gloated. "The bigger I get the more bloated you become, looks like I'll be the most muscular now and you'll just be a helpless blimp!"

Boz huffed and rumbled as his once muscled physique rounded out more and more, belly swelling outwards into his once hard pecs, which were soon big bloated pillows as well. The inflation had spread onwards to his legs that were thickening and ballooning up like zeppelins, paws becoming swollen nubs that he could barely wiggle. Soon the globular footpaws gave way under his enlarging form, and Boz fell backwards, landing upon the growing globes of his burgeoning buttocks, stretching out the yellow zebra stripe spandex that coated them more and more.

Simba laughed raucously with amusement at Bozs predicament, though continuing to work his upper body with the two weights he held. Still sitting on the workout bench he would get down into a half-crouch position, swinging one dumbbell at a time downwards than pulling it up with a heaving grunt to his huge chest, causing the muscles to ripple and bunch each time he did this. "Mm, I'm getting so big and tight, Boz, I could keep this up until I'm the Incredible Hulk, and you'll just keep inflating until you're as big as a whale!"

Continuing to grow, head sinking into his massively ballooning chest, cheeks billowing out like beach balls Boz tried to shake his head, but barely managed a wiggle. "P-please...no! Help!" Boz begged, growing cheeks starting to squeeze his lips together, making talking more and more difficult.

"What's that?" Simba responded in mock, tilting his head towards the distending form of the tiger "You want me to ramp up my workout? Okay blimp-boy, whatever you want!" Chuckling, Simba would grit his teeth and double his efforts, lifting the weights even harder, glistening beads of sweat coursing down his furry nose and at the sides of his cheeks.

"No!" Boz wailed, finding that the inflation began to quicken the moment the lion intensified his workout. Bigger and bigger his body would puff up, arms and legs being forced out to his sides as he rolled and wiggled upon his portly backside. Even at this awkward position, he could see Simbas muscles bulging out as he worked the weights, becoming even stronger than he was before. Frightened as he was by what was happening, he couldn't help but remain aroused, the already noticeable endowments protruding from within his speedo blowing up even more, right along with the rest of him.

"You always were a blustering air-head, now you're really blowing up! Looks like I'm the most muscular beast now, and you're just a dopey blimp!"

Swelling up like a jumbo parade balloon, Boz soon found himself unable to speak, capable of little more than wobbling and rolling. Eventually as his body continued to fill with the strange air, he found himself less and less concerned with it, as if his brain was filling with emptiness too. One lingering thing remained though, the sight of his mate becoming a muscle powerhouse glistening with the exertion of his weight lifting was making him hornier and hornier, though his body was growing bigger and bigger his bulbous spandex encased manhood was the only thing that felt like it might explode.

"Damn, all that working out has made me fuckin' horny..." Simba grunted, setting down the large dumbbells he had been using. He would then rest a broad paw into his loins, gripping the bulbous protrusion in his spandex brief and giving it s firm squeeze "A huge, masculine Goliath needs to get his rocks off..."

Simba would turn back towards the over-inflated tiger, Boz having become so massively bloated his swollen body had taken up nearly all the space the workout room could provide, huge belly touching the ceiling. In particular his eyes would be drawn to the gigantic yellow, black striped speedo still encasing the Tigers swollen bits, the speedo having somehow grown as well to accommodate Bozs puffy form.

"Bet my new tiger blimp is in need of blowing a nice big load, too!" Simba laughed, rising from the bench and lumbering closer to the enormous inflated Boz. Upon reaching the motionless tiger, the lion would wrap his enormous arms around Bozs rotund crotch, gripping his paw fingers into the shiny, silky spandex and hoisting his Herculean body upon it. Immediately Simba would begin grinding his entire body against the Tigers ballooned bulge, bounding and bumping into him.

Though his lips were scarcely able to move through his bulbous cheeks applying pressure to them, upon feeling Simba climb upon his overblown bulge, and began savagely humping against it, Boz couldn't help but moan lustfully. Though the process of having swollen up to the size of a parade balloon had been a frightful and confusing one, he had suddenly forgotten all of this in light of the intense arousal he had begun to feel once the inflation had approached its end. Unable to control his response his enormous globe of a bulge began leaking pre juices, the thick and slippery substance seeping out into his speedo, dampening it and causing it to become even more glassy.

"Good bloated boy." Simba rumbled, as he felt the moistness of the Tigers pleasure spread throughout the front of his speedo, against the lions fur, soaking him as well. Onwards the lion would grind and thrust his brawny physique against his inflated mates crotch, grunting and huffing as the primal desire for release overtook him. He would gradually increase his efforts, rubbing himself up against that slick glossy speedo harder and harder as his loins began burning with the increasing load accumulating within. "You're going to cum so hard, toy, cum on your hunky lion Titan, you're nothing but a big swollen plaything for my pleasure!"

Another blissful moan of ecstasy slipped passed the Tigers puffy lips, eyes rolling back into their sockets as he felt Simba continued to heave and propel himself against the Tigers gigantic bulge. Boz knew he wouldn't last very long, having felt the nagging sensation of arousal the second Simba had stripped down to his clingy speedo. He felt the need to release his sexual juices becoming more and more intense, unavoidable, his massive bulge already pumping out a steady stream of pre as it jerked and pulsed within its Lycra prison.

Simba became more and more saturated in the Tigers premature jiz, knowing it was scarcely a fraction of what was to come. He would strengthen the force in his savage thrusting against his mates rounded body, bounding up against him, grinding and jerking as hard as he could, wanting to feel that building orgasm flooding all over him, as much as feel his own manly liquids released. "Come on, cum for me! Get your gigantic muscular hunk of a lion all soaked in your spunk!"

Unable to restrain the building pressure any longer, the enormous swollen speedo package suddenly erupted with a torrent of creamy juices. Instantly soaking through the clingy yellow spandex of Bozs speedo, the thick wet spunk exploded through the skimpy material, bursting out in massive gobs that splashed over the hulking lion clinging to him. Gobs and gobs of the sticky goo would be propelled from the tigers pulsing and jerking manhood, unable to exert any control over it even if he wished too. So powerful were the intense spasms of his orgasm the massively bloated Boz would convulse and bob about, on the verge of tipping sideways had the lion not been balancing him with his muscular weight.

"Good toy!" Simba said approvingly, just as the mighty spurts of the Tigers cum doused him, drenching his golden fur in thick endless streams of the Tigers ecstasy. Had the lion not been gripping so firmly upon the inflated speedo bulge, he would have assuredly slipped off. But even as the yellow, black striped bikini became soaked he managed to remain where he was, coaxing more and more of the Tigers cum out by continuing to hump and grind his entire body against his huge swollen bulge.

More of the Tigers spooge burst from his drenched speedo, oozing out through the saturated Lycra and soaking his lion mate in the thick gooey substance. His bulge continued to thrash and jerk about, still causing his immobile distended form to do the same uncontrollably. It wasn't until his climax began reaching its end that these intense spasms subsided, the flow of spunk beginning to gradually decrease, the gushing fountain of white juices becoming a much slower oozing discharge.

Still holding onto the expanded form of the once buff tiger, Simba would remain grinding and jerking his hips into the soaked speedo of the ballooned Boz. Back muscles tightened, rippling and flexing, his muscular butt undulating and tensing as well as he ground himself into the gigantic blimp of a spandex package harder and harder.

"Nnnngghhh! So fucking close, I'm gonna blow!" Simba roared, just as he too released his manly seed into his speedo, cock spurting out gobs and gobs of thick jets of spunk. Though a sizable load, even as it seeped out through his own speedo, the white slippery goo was lost amongst the already doused fabric of the Tigers overblown speedo. Despite this, the lions manhood would continue to erupt, spilling more and more of his masculine seed until he too was completely drained.

Short as the orgasm seemed to be, it seemed to last an eternity, as the golden felines spandex contained shaft would pump out a few remaining spurts of seed with intense pulsing spasms. Spent, the lion would slouch up against the squishy, totally soaked crotch of the inflated tiger, grinning in the afterglow of his orgasm and rubbing his spandex coated cock into the bulbous surface of his mates crotch to coax out even more spurts of cum.

"Very satisfying." Simba would purrumble, squeezing his body against his mates expanded bulge in the form of an affectionate hug. "Suppose I should return you to normal...but I'm not sure I want too." He chuckled.

Boz, having felt the exhaustion of his own massive climax, scarcely jiggled or even twitched, even as Simba continued to buck and grind against him. Once his own orgasm was complete, he had felt the lions bulge twitching and thrashing as he had had his own powerful ejaculation. The tiger couldn't help but sigh, hoping it was all over, having enjoyed the helpless inflation and the orgasm that had followed to some degree, but wanting to be turned back to his original hulking physique all the same. When Simba suggested he might not return him to normal, Bozs eyes widened, and he would wiggle and wobble about in protest, still unable to speak with his cheeks puffed up as they were.

The lion would merely laugh as he felt the alarmed motions, clutching onto the tiger with a firmer grip so not to be tossed off "Oh calm down, I certainly need to do something to get you out of here, you'd never fit through the doors like this! No, I've got an idea to make us both happy..."

Simba would hop off from the tiger blimp then, only to lumber over to where he had left his gym bag next to the bench he had been lifting weights upon. Wrenching it up off from the floor, he would haphazardly place it upon the surface of the bench, before reaching into it with a paw. He would rummage around in it for a moment, before pulling out what appeared to be a rubber nozzle, like what that you would find on an inflatable pool toy.

"We need to get all that air out of you..." Simba stated through a sly smile, padding back over to where Boz still lay upon his massively air filled behind "So I brought along this enchanted valve, it'll stick right too you, see, and all that air will come out..." Simba would point at the nozzle with one hand, though unsure of why he bothered with the gesture, Boz couldn't see him over his bulbous belly! "Bit of a side affect with it though, after I put it on...it won't come off, in fact you'll be kind of like a pool toy that I can inflate whenever I like! Why you may even become vinyl, I'm not sure, haven't tried it yet but I'm eager to see what happens!"

Simba would close the distance between the pair, and though Boz, having heard what the lion had said and desiring him to find another means to deflate him could do nothing to show his opinion in the matter, cheeks still bloated and forcing his lips shut tight. Once Simba was close enough, he would none too gently hop back upon the inflated Tigers bulbous belly, and once gaining a firm grip upon him with one paw, would take the rubbery valve and push it up against the Tigers belly button. Like a suction cup it would hold there, and, would instantly begin to glow with a bright blue luminance as it permanently attached itself to Bozs body. As speculated, the Tigers once furry form would begin taking on a glossier sheen, as his flesh and fur would become more rubbery and latexy.

"Well it appears it does change you into a pool toy!" Simba marveled with a laugh, before he would flick a paw finger against the rubber stopper of the valve, opening it.

Boz would feel little more than an alien tingling sensation as the rugged nozzle took hold and fused itself against his ballooned belly. The same strange sensation would move steadily along his body then, not ceasing until it at last spread to every inch of his overblown form. Boz could feel himself becoming entirely vinyl, it was an intense, almost erotic experience, and despite having climaxed mere minutes ago, he felt his speedo becoming tight once more as the arousal flooded through him.

"That's my big tiger..." Having placed right upon the soaked silky speedo Simba felt as the Tigers inflated manhood began to firm up. This occurred despite the fact that, with the nozzle opened, and air begun whooshing free of the Tigers body, he still remained rigid in all the right places.

The feeling of the air expelling itself from his body through the nozzle was almost as enticing as the sensual pleasure the transformation has inspired. Boz never would have guessed deflating could've felt as pleasurable as inflating, but somehow it rivaled the previous sensation. At the same time, Boz could feel himself gradually returning to his original form, as his body decreased more and more in girth. Slowly, as Bozs once blimp sized body would again show signs of muscular definition, starting with his arms. His legs and chest would soon follow, his decreasing belly being the last to once again show signs of a chiseled physique.

As Bozs bloated form diminished, Simba would be forced to hop off, grinning in satisfaction at the sight. As Boz returned to his original muscle bulged self, he would cross his arms a moment, then reach out a paw to press a fingers against the Tigers burly chest. Now made of air filled vinyl, it gave way, the lions finger sinking into it like he was pushing it into a pillow. "Looks like I'll still be the most muscular one, and you'll just be full of air!" Chuckling, Simba would press the nozzle on the Tigers belly to close it, so no more air would escape.

"You can't leave me like an inflatable!" Boz whined, grunting as the belly button plug was closed "I was supposed to pose off in a big bodybuilder competition this weekend!"

"Guess I'll be taking your place, my buff balloon pet." Reaching his paw towards the Tigers rubbery chin, he would draw a finger along its underside. "Just be thankful I don't let any more air out and let you deflate entirely! Which I just might do if you don't behave yourself like a good pool toy..."

"Pool toys don't even move!" Boz grumbled, eyeing Simba with agitation "C'mon, get this thing offa me and change me back!" Boz demanded, reaching down to pull and yank on the nozzle, trying to get it to come off with no success.

Simba frowned "Well, that can be arranged too, if you keep acting up! Stop fussing with that, you'll just end up letting too much air out and won't be able to close it yourself, then I'll just have to let you deflate and carry you home in my duffle bag."

"Fine." Boz replied grouchiest, ceasing his attempts to detach the rubber nozzle. "But seriously, you're not going to keep me like this, are you?"

Simply smiling coyly, Simba would lumber back to where he'd set the duffle bag down, pick it up, then sling it over his shoulder. He would then proceed to head towards the door, retrieving his discarded nylon workout shorts and throwing them over his shoulder as well, not bothering to put them back on.

Not having received an answer, Boz would head off after Simba, anxiously awaiting some kind of response "Simba...did you hear me? Come on this ain't funny!" He complained

Still not responding, Simba would push open the door upon reaching it, stepping outside. Boz would of course be close behind, continuing to desperately repeat his name in question, and still never getting an answer all the way home. The lion would only smile to himself, with that same, knowing expression.

This is a random thing I thought up several months ago, just never got around to finish it...had wanted to post it for Simbas b-day, but the story and pic required much more work! These things always get away from me...stories, I intend them to be short and they just take off! Anyways, I liked what I ended up writing so much I did a follow-up piece, began one anyway...and hopefully don't take several months to complete that too!
