Atari flashed a mouthful of sharp white teeth as he watched a new customer walk up to the doors of his gym. The bulky, broad-shouldered tiger leaned over the counter, resting on his elbows to either side of the open magazine between them, and watched as the hare approached the glass. He glanced at the clock on the computer used for check-in and registration on the counter next to him - it showed 2:05, well after the lunch rush and well before the evening regulars. Thanks to the timing and the unseasonably gentle, sunny spring weather outside, the gym was absolutely empty save for Atari.

The tiger looked the part of a gym owner. Tall at seven-foot-four with a huge pair of pecs that strained against the T-shirt stretched across his pelt, he stood up straight as the new customer opened the glass doors to the gym. The tiger's gym shorts stretched across his thighs, hinting at the bulge of a large maleness within. On anyone else, those shorts would hang loose and baggy, but the tiger's muscular figure filled them out nicely. The feline's eyes narrowed just a touch and his tail tip twitched behind the counter as he got a good look at the approaching male.

The rabbit was short, probably under five feet, and thin as a rail. No meat on him at all, even his legs, which rabbits were often known for. Light gray fur mixed with a few splotches of white patterned around his eyes and throat. A pair of tight skinny jeans clung to his equally skinny legs while a black t-shirt hung loose around his shoulders. The rabbit hesitated when he opened the swinging door and saw the huge tiger behind the counter, but slipped inside and approached after straightening his back. He reached up with a paw and smoothed back his oversized ears, which flopped backwards, hanging straight down his back nearly to the waist of his jeans. White fur coated the tips of each gray ear.

"I'm Atari. How can I help you?" the tiger rumbled, his voice sounding loud in the otherwise quiet foyer.

The rabbit stopped in front of the counter and looked up, almost having to crane his neck to see past the tiger's pecs and belly.

"Do you have guest memberships? I'm looking for a new gym," he said in a soft, high-pitched voice.

"Sure, I can let you in for free today," Atari said. "Anything in particular you're looking for in a gym?"

The rabbit shrugged. "Well, I used to be a runner, but that was years ago. I'm thinking about doing some strength training."

Atari grinned and leaned over, bringing his head down to the rabbit's height as he leaned over the counter. The hare instinctively took a step back as the big male's sharp teeth flashed a brilliant white.

"Well, you came to the right place," he said. "I don't even have any treadmills." He decided not to mention that he'd broken three of them himself before deciding cardio was better accomplished running outside, where his weight couldn't break the machines or the sidewalks. And getting lots of stares didn't hurt, either.

The hare's lips turned up in a brief smile as some of his nervousness faded. His eyes drifted across Atari's chest, even venturing lower for a moment before snapping back up.

"Locker rooms are over there," Atari said, gesturing with a huge paw. "Go ahead and change and I'll run you through a training regimen on the house - got no appointments for a couple of hours."

"Hey, thanks," the hare said, turning towards the hallways with the locker rooms. The locker rooms had doors connecting to the interior of the gym as well.

Atari watched the skinny rabbit off, then turned and went through the swinging double doors into the gym proper. He licked his lips and grinned again, even more widely than before. He'd caught the rabbit stealing a glance and had a good feeling the little male would be in the mood for more than just a workout.

The tiger rumbled as he set up some weights. Rabbits were always good for a fun time.

A few minutes later, the lanky hare approached him dressed in a loose pair of gym shorts and a somehow baggier t-shirt than the one he wore earlier. It had the logo of another gym in town, but Atari pretended not to notice.

"I'm going to run you through a really basic regime," he said, motioning for the rabbit to join him at the free weights. "These are simple exercises you can practice at home as well if you get your own free weights some time."

"You don't use the machines?"

"They're fine. I just prefer the free weights, especially for beginners - you'll see gains quicker with them."

"Oh, okay."

"What's your name, by the way?"

"I'm Montaro," the rabbit said. "But everyone calls me Monty."

"Nice to meet you, Monty. Now come over here and grab a weight, then do what I do."

Atari leaned over and picked up a pair of dumbells, one in each paw. Monty's eyes widened when he saw the "40" etched into the sides.The tiger noticed and grinned as he let his arms rest at his sides.

"I'm gonna take it a little easy," he said, his voice a teasing purr. "Usually I'm in the fifties. Go ahead and pick up a couple fifteen-pounders. Should be good for what we're going to practice."

The rabbit swallowed before trotting over, trying to keep his eyes on the gym owner's face - not the massive tiger's bulging biceps or enormous thighs or taut rump or... well, all of him, pretty much.

"Okay, so the first thing we're going to do is a great all around workout," Atari said. "First thing to do is hold the barbells up near your chest, like this."

The tiger curled his arms, flexing his biceps and causing the thick hair of his pelt to splay against the inside of the t-shirt. He waited for Monty to follow suit, then dropped low, squatting down.

"Then go into a low squat like this."

Monty's eyes widened further when he did, easily dropping himself into a crouch in front of the tiger. He could see the outline of a very large sheath and equally formidable testicles bulging out between the feline's thighs. Hamstrings squeezed and stretched as the tiger settled himself into the crouch along with the rabbit, a smirk on his large muzzle.

"Right, then just push yourself up, and as you do, press both arms over your head - watch!"

The tiger lunged upwards, easily pushing both forty-pound weights high above his white and black ears. The shifting of his clothes caused his shirt to pull upwards, revealing some of his smoothly-furred white belly.

"Now you try."

Monty did, closing his eyes as he silently prayed that he wouldn't get aroused watching the oversized tiger flexing right in front of him.

"That's it! These are called 'thrusters,' by the way. I like to use them to warm up."

Atari put Monty through several more reps. The rabbit kept up fairly well, which the tiger put down to his cardio training, but by the end of the second set, he faltered.

"There you," Atari said, dropping the weights. "Nice and easy, right?"

"Right," Monty said, panting already. The tiger, he couldn't help but notice with some jealousy, wasn't even breathing hard, despite doing the same number of reps.

"Okay, let's try another one..."

The tiger showed the rabbit several more exercises before he called for a break, not wanting to wear the rabbit out entirely on his first day. Not yet, anyways.

He offered the hare a water bottle before slugging back most of his. He'd worked up a sweat and panted to cool himself down. He stepped in front of one of the several large fans mounted throughout the gym and sighed as the cool air ruffled the fur on the back of his neck.

The fan also helped spread his scent. Atari could tell the rabbit was getting a nose-full of it now - the blinking, the confused glance, the realization of just where that ripe masculine scent came from... Atari took another drink of water to hide his grin as the much smaller male's shorts tented. The tiger couldn't help his long tail from twitching with anticipation between his legs, though.

"You're doing pretty good," Atari said, stretching his arms over his head. He made a show of leaning back as if flexing his backside, but really he just wanted to shove his hips forward, ensuring the shorts pulled tight once more around his sheath and sac. Flaccid, the tiger's maleness was as thick as a liter bottle. He could get his hand around it just barely while it was soft. When he was fully aroused, as the tiger suspected he soon would be, his fingers didn't reach by a long shot.

The stretching display had the desired effect on the rabbit, who stared at the huge feline, oblivious to the throbbing in his gym shorts. Monty's jaw dropped open and stayed there as his nostrils flared, greedily inhaling the musky, dense scent of the tiger's exertions. His eyes were wide as dinner plates as his gaze lingered on the tiger's crotch. He shifted his thighs instinctively, unable but to imagine the tiger's package growing, growing, bigger, bigger...

His paw bumped into his erection, dragging his attention back to reality. He gasped and pulled at his shorts, trying to arrange himself so it wasn't so obvious by tucking the tip into the waistband and pulling his shirt down. Another glance at the tiger showed the big male still in the throes of stretching, twisting back and forth to work out a kink in his back or something. Monty sighed. Hopefully the gym owner didn't notice. He didn't want to get thrown out for being a perv or something. The rabbit narrowed his eyes, trying to focus on the weight lifting lessons he'd been taught instead of the deliciously masculine scent invading his very soul...

"So, Monty," the tiger said.

Monty let out a yip and almost fell of the weight bench, surprised at the volume of the tiger's voice.

"Heh, sorry. Anyways," the tiger said, walking towards the rabbit, "I think you've got potential. How about one more round of exercises?"

Monty could only nod as the tiger stood in front of him, blocking out the lights behind him. The rabbit stared up, mouth agape, in awe of the big feline's defined pecs and massive arms. His cock twitched against the waistband and he felt a little pre squirt free.

"Uh... I think... I might have to get going," he said, trying not to stammer. "Uh... but this was really helpful, I'll definitely come back..."

The tiger laughed and reached out, settling a large paw on the small lapine's shoulder.

"Not good enough!" the tiger said, grinning down at the rabbit. The tiger licked his lips as he saw the rabbit's gaze drop to the bulge between his thighs again. "I don't allow my customers to be quitters!"

The tiger scooted forward until his hips were less than a foot from the rabbit's muzzle. He dug his fingers into the smaller male's shoulder, claws just coming out to teasingly prick through the rabbit's shirt and fur to the skin below. The overwhelming scent amplified in power and Monty breathed deep. His eyelids fell halfway down as he leaned into the tiger's paw, a soporific nod his only response.

"Of course, we could practice a few non-traditional exercises as well," the tiger continued, voice dropping to a bassy murmur, "if that's what you'd prefer."

Monty raised his gaze at that, mouth still hanging open, ears twitching against his backside. The rabbit's eyes were glazed and his breathing shallow as the feline's pheromones overpowered him, subduing what little resistance he may have even attempted to offer. When the tiger's other paw slipped down between his legs, he jerked and gasped, then moaned as the feline's huge fingers squeezed his cock. He wasn't huge, by any means, but he was well-proportioned to his size, but to the tiger it must have felt like fondling a toothpick.

"That's what I thought," Atari purred. "This first exercise uses some other free weights."

Atari's paws left the rabbit and grasped the waistband of his shorts instead. With a single smooth motion, he pulled them down, dragging the front of the shorts down over his bulging sheath, which fell forward partly, but was held mostly upright along his lower belly. Lower, a pair of enormous white nuts tumbled free and hung across his thighs, shifting up and down as he flexed his hamstrings.

Monty leaned forward, still sniffing the air, breathing faster as he reached out with both paws. His fingers caressed the massive sheath first before sliding down and under those heavy nuts, letting them fill his paws before he tried to lift them. The tiger grinned as a few inches of black tigershaft spread open the tip of his white sheath. The tiger wasn't close to full aroused yet, but Monty couldn't believe the thickness. He moaned as the warm length slid against his cheek and then across the bridge of his muzzle. His fingers, meanwhile, kneaded away at the tiger's balls, clutching and tugging until the big male's length twitched and lifted from his face, only to fall back down with a bone-jarring thud.

Monty was sure he'd cum in his shorts right then and there, but he also knew that wasn't going to stop the huge tiger from doing whatever it was he had planned.

"Mmmhh... yeah, nice form," the tiger growled. "Let's see how many reps you can do next..."

One huge paw clasped the back of his head, wrapping both ears up in the feline's fist near their bases. Monty stiffened as he felt the tiger pull his head back and let out a groan of eager arousal that echoed through the gym. His ears were his weakness - a simple pinch, a tug, nibbles and licks and squeezes... it sent shivers through his whole body, making his hips wiggle against the weight bench.

Atari's other paw grabbed his growing length at the base and slid down, revealing even more of the heavy erection. Already a trickle of clear pre-cum bubbled from the tip, which by now was so large Monty was sure getting it into his mouth at all would be impossible. But the smell... the scent... the heat of the tiger's lust brushed those simple worries away.

And it wasn't like Monty was in charge of deciding what fit where regardless. With a paw still gripping the rabbit's ears, Atari simply maneuvered his tip to the rabbit's open muzzle and shoved forward, popping the still-hardening tip to the back of the rabbit's throat, instantly gagging him. Monty's cheeks stretched and his lips burned as he felt the tiger pull back and shove forward, pump pump pump, a steady rhythm similar to the speed they'd done the thrusters earlier.

"And ten!" the tiger said, his voice slightly strained as he pulled his hips back, dragging his flexing maleness free of the rabbit's stretched lips. The fat tip let out a fat gob of pre-cum that splattered across the rabbit's tongue and lips. Held back by the sheer tightness of the rabbit's muzzle, it was trapped in the tiger's cock before shooting free the moment he pulled back. Monty's brain screamed at him as he realized the huge feline's pre shots were twice as much as what he could produce on a good day when he actually came.

"Let's do another couple sets of that, huh?"

Monty's eyes squeezed shut as the paw gripping his ears tugged them sharply, forcing his head back. The tiger's hips smoothly pumped forward again, once more filling the rabbit's maw. Monty swallowed, unable to stop the blast of pre-cum from being pushed straight down his throat and into his belly. The rabbit's nerves, already on fire from the overdose of feline pheromones, accepted the protein-rich essence of the massive tiger with equal eagerness. Monty moaned, muffled as it was, while Atari's hips thrust forward, forcing his cock as deep as he could get it, not worrying about how rough he was being for the moment.

Despite the muscular feline's best efforts, he couldn't get more than a handful of his cock into the rabbit's throat, though by the fifth set he was managing to stretch the tiny rabbit's lips with growing ease, enough that his thick pre-cum pulsed across the rabbit's tongue and down to his stomach with ease.

Monty felt his cock dripping in his shorts. He'd never been so hard. Both hands splayed across the tiger's thighs as he helplessly suckled and swallowed, head moving exactly where the tiger wanted. Which was mostly down, then up, then down again. His eyes teared up as the salty, musky pre-cum washed into his belly, which churned and growled audibly. Monty ignored his boiling guts as he squeezed his hands around the tiger's thighs as far as he could reach, wanting nothing else at the moment but to feel that massive cock, now entirely rigid and longer than his forearm.

"Eight... nine... hffff... ten!"

Instead of pulling free on the last "rep," the tiger held himself deep. He leaned over, squeezing the smaller male's head between his huge balls and his hard, slightly round belly. Muscles from above, roiling balls from below. Monty's his eyes widened deep in the darkness of the tiger's crotch as he felt the urethra bloat against his tongue. A moment later a rich blast of tiger-jizz exploded down his throat. He couldn't swallow fast enough, not by half, and a lot of the tiger's seed sprayed out of his nostrils or leaked around the edges of his lips where the seal around the huge length wasn't quite tight enough.

"Protein shakes will help replace the energy you burn during long workouts," the tiger grunted.

Monty's legs twitched as his body flexed and shivered, trying to pull away as the flood of salty seed filled his belly. He couldn't tell how long it lasted, but by the time the tiger popped free and splattered the small rabbit with a few last ropes of protein shake, his stomach was bulging outwards, distended so far it hung over his thighs and knees, squeezing downwards against his erection.

"Looks like you overdid things," the tiger growled. There was pure carnality in his voice that made Monty's glazed eyes focus on the huge muzzle that lowered in front of him. "Gonna have to work all that belly fat off."

The tiger's hips pushed forward, grinding his log up the sloshing stomach and smearing more thick seed into the small male's gray and white fur.

"Fortunately for you, I've got just the workout to set you right."

Monty groaned as the tiger's paws handled him, easily lifting him as though he weight nothing at all, then shoving him down onto the soft blue mats in front of a barbell station. He moaned even louder as he felt his belly spread beneath him. His stomach was pumped so full of the tiger's seed that it lifted his hips up into the air, giving the tiger even easier access.

Atari took advantage eagerly, staying rock hard despite his recent orgasm. The big feline's paws wrapped around Monty's thighs, tugging him back as he slide his massive length forward between the small male's rump cheeks. He was so thick he couldn't even properly hot-dog the rabbit, but the fluttering of the hare's tail against his slick stalk made Atari shudder.

Monty's legs kicked and he squirmed helplessly as the tiger's fingers clenched around his thighs, not allowing him to move at all. The pressure came next. Monty knew it was coming. He tried to be ready for it. "This is happening," he told himself. But when that fat, warm tip pushed between his cheeks, stretching them apart and nudging against his hole, he couldn't help but squirm all the more.

"Funny enough," the tiger said, leaning over for a moment as he spoke, "this exercise is also called 'thrusters.' Heh."

The rabbit's squeal ricocheted off the walls, bouncing off the mirrors and echoing back into his own huge ears as the tiger's hips ground in. The titanic tigerstalk pulverized what little resistance the sub-five-foot rabbit could muster.

Atari's tongue hung over his lips as he leaned forward, grinding deeper, flexing his maleness into the small body beneath him. The rabbit was incredibly tight, but his cock was still dripping and spurting so much pre-cum that lubrication was the last thing the hare had to worry about. The tiger's paw shifted, running up the small male's side, and wrapped around his ears, tugging them back, forcing the rabbit's back to arch. With a guttural growl, Atari forced the last few inches of his throbbing arousal into the rabbit's abused body. The outline of his flexing length appeared against Monty's belly, lewdly stretching him in ways the rabbit never imagined.

But something else was happening, too. As Atari slowly dragged his hips back, taking pleasure in every single millimeter of movement, Monty felt another pressure. Unlike the pressure of the feline's fuckstick, this pressure was different. It was all over, not just under his tail. It pushed out, fighting for freedom, bulging and pushing from beneath his gray pelt. The rabbit's belly churned louder as the tiger's seed and pheromones combined into a potent brew inside the tiny rabbit's body.

Monty started to grow.

It was slow at first, barely noticeable for the first dozen thrusts. But as the tiger gasped for breath above him, praising his form and counting out reps, Monty's shoulders stretched. The paunch in his belly drew up slightly, the more and more as the tiger's seed filtered into his arms, his legs, his chest and neck.

The tiger kept a firm grip on the rabbit's ears, using them to keep the rabbit pushing back against his thrusting hips. He closed his eyes as the rabbit's rump thickened up, pushing against his thighs. Monty's moans sounded lower and lower as his chest swelled. Cords of hard muscle shifted the fur riding them as he wrapped both paws around the legs of the dumbbell station, holding himself in place as the tiger pounded away from behind.

Monty could feel it. He could feel the power. The size. The muscle. He shifted his hips, drawing his knees up slightly as he got taller and taller. His shoulders widened and his neck all but disappeared as the soft gray fur coating his belly pulled taut around the ten-pack of abdominal muscles that ran from his groin to his ribcage and extended around his sides. Every muscle perfectly defined, perfectly huge, perfectly displayed beneath his pelt. The huge shaft buried in his guts continued to pound away, forcing his abs to shift as it prodded outwards.

Monty's biceps rippled as every feline thrust drove more potent seed into his body, further accelerating his growth. The t-shirt that hung so loose around his chest and arms now stretched to the breaking points as the seams pulled apart. One deep breath was all it took for the fabric to tear down the middle, from the neckline through. Monty groaned as the tiger's thrusting accelerated, driving into him hard and rough - now that his body could handle it, he felt nothing but lust. The smack of Atari's sac hitting the back of his thighs drove Monty wild - and he heard every single smack with his huge ears.

Atari switched his grip, straddling the rabbit's legs as the once small male grew taller than him. Holding one ear tight in each paw, the feline used them like reins as he slammed his hips down and in, over and over and over again, each hilt sending a fresh blast of pre-cum flooding through the rabbit's guts.

Monty clenched and growled, groaning and moaning, pushing back against the muscular tiger as his fingers tightened around the steel bars forming the legs of the dumbbell station. He curled his shoulders back, every muscle flexing at once as he felt the feline hilt him and hold. Atari's chest pressed into his backside and sharp claws reached around, pinching at the fat nipples protruding through Monty's chest fur.

The second of the large tiger's orgasms was no less intense than the first. Monty's new body, however, could handle it and then some. His ass rhythmically squeezed and squirmed, hard balls of gluteal muscles massaging the tiger's every last fat inch.

The tiger's paws groped at Monty's pecs, instigating a second surprise for the rapidly enlarged lapine. A second tearing noise echoed through the gym followed by a thud, then a deep guttural gasp. Strands of the rabbit's gym shorts clung to a dark pink cock thicker than Atari's, which stretched from the rabbit's hips to his nips. The rabbit's waist was trim, a V-shaped torso, accentuating the bodybuilder-esque muscles adorning his body. Compared to the tiger, he looked more muscular, though Atari wasn't jealous - the rabbit not only had shorter fur to show off the musculature better, but the tiger's focus was on strength training. Which is why he was able to do what he did next.

With a grunt, the tiger wrapped both arms around the rabbit's belly. His thighs and calves strained as he deadlifted the nearly 350-pound rabbit, holding him up in the air so the tiger's cock flexed upwards into the muscular lapine's rump.

Monty wrapped his paws around his cock and hiked his legs as the tiger's orgasmic thrusting pummeled him anew. His cock ached between his paws until a few moments later the tip erupted, sending ropes of cum more than twenty feet to splatter across the floor-to-ceiling mirrors on the far wall. Rabbit and tiger alike moaned with lust as the tiger's body flexed, driving his hips upwards.

It was many minutes later before the tiger lowered Monty to the floor and leaned into him, gasping and panting as he draped himself across the huge male's backside. He could feel Monty's dorsal muscles flexing and purred as his thickness jerked inside the beefy bunny's backside. It was several minutes after that before either was recovered enough to disentangle themselves and get to their feet. The tiger's cock drooped down past his knees as he looked around the gym.

"Ah, I should have put down a tarp!" he said, dismay in his voice as he realized almost the entire free weight section - and a good portion of the opposite wall - was liberally doused in musky bunny jizz. "Time to get the hose..."

A huge paw slid down Atari's side and cupped his backside. The tiger grinned as he turned his head to look at the massive, eight-foot-tall rabbit standing beside him.

Monty's voice was deep and low as he stared down at the tiger, a fresh hunger in his eyes. His maleness flexed upright, still hard, and slid across the tiger's belly as the rabbit moved close.

"I'll help you clean the mess," he said, smoothing his ears back with his free paw. "Can't believe we did this right out here where anybody could have walked in."

The tiger shrugged and grinned. "I'm surprised a big guy like you doesn't know basic workout routines."

"I know a few now and you'll have to show me more later," the huge rabbit replied. "But first, let's hit the showers. Does the gym offer rubdown services?"

The rabbit's fingers dug into Atari's glute, making the tiger jump a bit. The feline growled and reached down, stroking a paw across the semi-hard shaft drooling over his feet.

"In your case, yes," Atari purred. "And afterwards, how about getting a membership?."
