Content warning: M/M, locker room, size theft

* * *

Caleb was one of those enormous, muscular, huge males that was way shorter than he appeared from a distance. The sabretooth tiger chalked it up to his heavily-developed body: round shoulders, plump and fat pecs, solid and rippling core - all the traits a workout machine like he needed to show off. Caleb's choice of workout clothes emphasized his hard body. Despite clocking in at a relatively meager five-and-a-half feet (compared to some of the other patrons at the gym, at least), the sabretooth stood out with his distinctively bright orange fur, dark black stripes, and skimpy tank top and shorts, neither article of clothing doing all that much to hide the deep crevices and curves formed down his legs from the strong hammies and calves.

The tiger was just leaving the locker room, tail ticking side to side behind him, and was carrying a pair of protein shakes in widemouthed plastic bottles. Caleb's bright blue eyes shone as he practically pranced over to the free weight section in the far back corner of the gym, passing by rows of treadmills and weight machines along the way. The tiger twitched his dark brown ears at a few people he knew along the way and paused for a brief chat with a huge white tiger before reaching the free weights section, where a large bull sat on a bench doing arm reps.

"Panic! Here you go!" Caleb said, handing off one of the shakes to the bull.

Panic took it with his free hand and tipped his long muzzle back. The pale muzzle opened and he poured the shake into the back of his throat, chugging almost half of it before pulling the bottle away from his muzzle. Besides the pale patch of hide surrounding his squared off nostrils and mouth, a dark layer of black covered the rest of his large, muscular figure. Patches of a slightly lighter gray color swept across his hips, left knee, and around his left shoulder, interrupting the otherwise contiguous dark shade. A pair of white horns sprouted from the sides of his head, above each pointed, turned-down ear. The horns curved upwards and pointed towards the ceiling, bowing in towards each other just slightly at the sharp and well-polished tips.

"Thanks! Ahhhh, that hit the spot!" Panic said, grinning at the sabretooth. He ran his large, blunt fingers through the deep purple hair running back from the top of his head and down his neck, ending in a point below his shoulder blades. Matching purple hair ran under his jaw, forming a long braided beard that dropped more than a foot down over his chest, ending midway between the taut, round pecs. Panic set the bottle down on the bench next to him as he powered a few more reps with his arm, popping his bicep and smirking at the sabretooth. "Getting a good view?"

Caleb grinned and shook his head, though as he turned to pick up a few free weights for his own use, the sabretooth's tail pressed across the bull's flat muzzle, tickling the golden hoop piercing his nostrils.

"Hey!"

A shadow loomed over Caleb from behind, then massive arms swept around the tiger's shoulders. The bull's hard chest shoved into the back of the feline's head, squeezing down against the soft fuzz atop his head and flattening his ears. The much taller bull grinned down at the feline as his hips moved suggestively forward.

"Better behave, kitty!"

The sabretooth grinned and tipped his head back, meeting Panic's muzzle for a brief peck as the bull's fingers dug into Caleb's hips.

"Mmmh, that's better, kitty cat. Now be a good puss and work out for daddy. Heh heh..."

Caleb rolled his eyes and squirmed away from Panic, playfully shoving the bigger male back. The feline didn't appear all that perturbed by his boyfriend's teasing today - normally, the tiger would have snapped something sharp right back at the bull for teasing him about his size. But not today.

The sabretooth grinned, muzzle spreading over the huge fangs dropping past his chin, as he curled a 100-pound weight in each paw opposite the other, working them up and down to make his biceps thicken up just like Panic's.

"Good kitty, that's it. Work those arms for me."

Panic's grin made Caleb smile back and the tiger turned around to avoid the mischievous look on the bull's face, shaking his head. Little did the buff bovine stud know...

"Caleb! Panic! You can relax, we're here, it's alright to start working out now!"

The bull and tiger looked over simultaneously at the panther and dragon approaching down the aisle between the weight machines. The panther was a bit smaller overall than the bull, with a lush black coat that shone and gleamed around the curves and bulges of muscles running up and down his body. He was broad shouldered and shirtless, and sported a prominent, shameless bulge in the front of his bright, eye-poppingly yellow shorts.

The dragon, on the other hand, was massive, easily standing three feet taller than the bull. Simon drew attention wherever he went thanks to his immense height, but it also didn't hurt that the dragon's tight-knit scales perfectly outlined and revealed every little inch of power on his huge body. The scales shimmered, a pearlescent blue that faded from color to color as the male moved under the lights. He grinned down at the tiger and bull, nodding, as the much more active panther leapt into the free weights and pulled out a few that appeared to be far too large for him to handle.

"How's it going, Simon? Work going alright?" Panic asked as the huge male took a seat next to him on the bench.

The small talk continued as the four males worked out. Caleb in particular built up a head of steam as he watched Panic's protein shake disappear. The sabretooth volunteered several times over the next hour and a half to fetch more. Simon and Panic worked on their upper bodies while Caleb and Bagna alternated between upper and lower. By the time each of the four finished their personalized routines, the free weight area positively reeked of sweat and musk. The sabretooth took a deep breath and grinned.

"Meet you back in the showers?" he asked the bull, swatting the large, muscular bovine on the rump as he passed.

Panic nodded as he hung back to chat with Simon and Bagna. Caleb walked to the locker rooms with long strides, trying to make it there as fast as possible. He was having trouble hiding the bulge in his gym shorts and didn't want to give away the game by popping a boner in the middle of the gym. No, this plan required a little more subtlety. Opening his locker, Caleb grinned as he eyeballed the protein shake powder left in the clear bottle on the left. The bottle on the right, which featured a store label, was mostly full, and was what Caleb drank all day. The bottle on the left, the clear bottle, that was the special bottle, and it was going to ensure that his boyfriend wasn't going to make fun of his size anymore.

Caleb bit his lower lip, long fangs shifting as he reached down with both paws, arranging and adjusting the fabulously thick bulge gradually swelling inside his shorts, a thick ridge of feline meat that was impossible to fully disguise, not that Caleb ever particularly tried under normal circumstances.

The tiger's ear ticked backwards as he heard the door to the locker room open. Grabbing his towel and shampoo, Caleb swung closed his locker door and strutted towards the showers, stripping his shorts along the way. The tiger hung them and the towel on a peg outside the lockers, set the bottle of shampoo on his thick maleness about three-fourths of the way down the length, and strutted into the steamy tiled room, tail disappearing into the billowing clouds of water vapor last.

The tiger soaped himself up thoroughly, making sure he applied the special cleaning agent to every little part of his body. His fingers squished between his pecs, under his arms, and down between his solid, thick rump cheeks. He rubbed vigorously under his jaw and behind his ears, even sitting down on the tile to make sure he could reach every little nook and cranny on his wide feet. By the time he was rinsing, satisfied he'd applied the special shampoo thoroughly, he heard Panic's voice, along with the others, approaching the shower.

It didn't take long for Panic to find Caleb. The tiger was wetted down with the hot water, fur plastered to show off his impressive body. He bounced his pecs as the bull strode towards him, hard hooves clicking on the tile. The bull's dark maleness was half-hard and glistened as drops of water beaded on the warm, smooth skin stretching away from the hard, powerful belly above. Caleb and Panic met under the showerhead, muzzles parting and turning, tongues out. Caleb had to turn his head upwards to meet the bull's mouth, but did so eagerly as he reached his paws out and around, snagging his claws into the larger male's thick hide and tugging him closer, squeezing both fat malenesses between them between their bodies. Caleb growled as he felt his fangs sliding across the bull's nostrils as the sloppy, tongue-laden kiss continued. Panic's maleness throbbed, hardening with urgency as it squeezed against the sabretooth's dense abdominal muscles.

Time stood still for the duo as they made out under the shower, the hot water and steam adding to the heat they felt coming from within. Caleb especially felt his heart thud against his ribs as a strange new sensation flowed down his throat and spread through his torso and spine: power.

Panic didn't notice, but Caleb was growing. And with every moment the kiss went on, the sabretooth tiger grew larger. Not only that, but the larger Caleb grew, the smaller Panic got. The process was slow, barely visible with the naked eye. The tiger chose his locations carefully, though - the heat of the water helped distract the dark black and gray bull. Caleb's paws slipped up higher, teasing over the bull's backside, stroking over his shoulders, squeezing them as he felt his arms thickening, bulking, his whole body stretching outwards in all directions at once. The feeling exhilarated him. Caleb thrust forward, unable to help himself, as his fat maleness spread against the bull's chest, reaching from Panic's belly button all the way to his shoulder.

The bull's eyes widened as he realized what it was he was feeling against his torso. He stared upwards, trying to figure out why it was Caleb looking down at him. The tiger's neck was almost completely nonexistent, subsumed and surrounded by impressive amounts of shoulder muscle; Panic, meanwhile, went the opposite direction. Still muscular, but leaner, smoother, similar to how he'd been when he first got serious about bodybuilding.

Panic let out a groan, though it was muffled by the enormous feline tongue stroking around the insides of his muzzle and occasionally pushing to the back of his throat. He couldn't move, not with the incredible biceps squeezing around his arms, pinning them to his sides and forcing him to slide forward into the huge pecs. The water meant no fuzz to soften the blow of bouncing across those huge muscles, not that Panic minded as he felt Caleb's body shudder and ripple, growing even larger.

"Nnnnfffgghgh... Caleb! What... what are you... oooh... oh, fuck me!"

Panic closed his eyes, muzzle returning to Caleb's after he managed to momentarily pull himself away from the feline's long tongue and fangs. As Caleb's mouth dipped down, licking and nuzzling over the side of his neck and the crook of his shoulder, the bull tipped his head back, trying to think of a way to stop the tiger, to get his muscles back, to... to... to get the big sabretooth daddy to fuck him raw.

No! Panic closed his eyes, shuddering as he felt those incredible fangs push across his neck. The tiger was growling, low and hot, while his hips stroked forward, roughly shoving that magnificently huge cock against his chest. He needed it so badly. He had to have it. Panic wriggled, moaning, head going side to side until Caleb's paw reached up and grabbed the braided beard coming from the bottom of the bull's chin. Panic gasped, eyes looking up at the much taller tiger's face while the huge paw tugged his jaw downwards.

"Much better," the enormous sabretooth purred. He was easily over six feet tall now, while Panic rose to just over his shoulder. The cat probably had a good hundred pounds of muscle easily on the bull now as well. "Well, bullboy, what are you waiting for? Turn that ass around for me. Heh heh..."

Caleb's voice boomed through the showers, barely diminished in volume by the hissing showerheads. He sounded deeper and more masculine than he did before, and as he grabbed and shoved Panic into place, the tiger's belly pressed forward, grinding his even deeper, thicker 12-pack of pure muscle against the bull's backside. Panic had to curl backwards, chest and stomach shoved into the tile wall followed by his muzzle when Caleb wrapped a paw around the back of his head.

"Who's the bitch now, stud?" the feline purred, lips brushing past the bull's ears before the tiger took a long, slow lick from the base of the right horn all the way to the tip. Lower, his thick shaft squeezed between and along the bull's rump cheeks, running up his back and dribbling a steady stream of thick, clear pre-cum.

Even with the water running all around them, or perhaps because of all the steam in the air, Panic's nostrils flared with the intoxicatingly rich, masculine scent of his boyfriend. The sabretooth's scent invaded his mind, wrapping around the control centers and implementing a whole new firing mechanism. The bull's hips shuddered, jerking forward as the tiger leaned forward, surrounding him completely from behind as his front flattened into the wall. The bull's hooves dangled a few inches off the floor as he continued to shrink, all his formerly glorious muscle mass bulking up the sabretooth instead.

The deep, low growls continued, punctuated by a few sharp moans and gasps, though it was hard to see what was going on in front of the huge feline. Caleb's tail swung side to side behind him as his fingers rolled up and down the sides of the bovine's body, pecs surrounding Panic's head and pressing his horns harder into the wall. As the tiger drew his hips back, he created some space between their bodies for the first time in a long while. The huge, fat tip of his massive pink shaft left a wet trail down the black and gray bull's backside, then slid around the side of his long, tufted tail, before lodging underneath, clenched automatically by Panic's plump, pert glutes. Twin rivulets of pre-cum welled up, pooling in the bull's crevices before spilling over and around the huge cheeks towards the back of his thighs and knees.

"Nnngghh... Caleb... what did you do?" the bull gasped. "I... I... oh, fuck, I need it so bad!"

"Just a little surprise for you, honey," the massive sabretooth grunted, his deep voice rolling from his huge muzzle. A tongue spread across the side of Panic's head, easily covering all of his cheek and temple. "Now try not to make too much noise, babe..."

The bull did, in fact, make quite a bit of noise as the tiger's thick tip smooshed and flexed forward, grinding up and into the squirming, de-muscled bovine's backside. His lean arms trembled as he kicked his feet in mid-air, unable to do much else as the tiger's paws wrapped around his hips, holding him in place while inch after inch slowly stretched him open. The impossibly wide, fat thickness pulsed, hard as steel, veins popping. Caleb closed his eyes and licked his lips, tongue slipping around both sides of his long fangs, as he leaned back, staring down past his muscular pecs towards the wide hips and plump backside of his boyfriend. Panic's arms, finally free, pressed forward, palms flat to the tiled wall in front of him. His fingertips scraped over the mortar as the tiger bounced forward. His massive cock wrinkled with the pressure of the bull's hips working back against him, but after an extra twist and pull, his massive length straightened, and a long and desperate mooing echoed through the showers.

While Panic painted the wall in front of him white, unable to stop the intense orgasm as his boyfriend's incredible thickness spread him open, Caleb admired his handiwork. One huge paw wrapped around Panic's shoulder and pulled the gasping, squirming bull upright, forcing him to sit straight on the massive shaft. Caleb leaned his head down, jaw resting over Panic's shoulders, a smirk on his muzzle as his ears twitched, picking up every little gasp and moan from the squirming bull. The sabretooth stared down, eyes wide, closely examining the formidable bulge in Panic's belly. Pressing his right paw out, the huge sabretooth poked at the bulge in the bovine's belly, and was quickly rewarded with a mess of squirming and gasping. Caleb shivered, feeling the pressure on his cock from outside of the bull's body, as he slid his paw over and around the outline of his shaft. Panic gasped, tongue flopping out of his muzzle as he came again, thick bullshaft flopping up and down. His cock and balls were about the only thing on him that hadn't shrunk during the process, leaving the lean, muscular little twinkbull with an impressively large shaft.

The tiger growled louder as he humped his hips, keeping his palm spread across Panic's belly as he did so that he could feel his shaft moving inside, forming an obscene ridge against his fingers through the bovine's dark black and gray hide. Panic's hands reached up, fingers digging into the thick neck fur around the tiger's head, as he used one paw to squeeze at the bull's belly and the other to guide the shuddering male up and down over his thickness. The tiger's other finger slid up the bull's neck and down his muzzle, hooking inside the corner and tugging the shrunken bovine's head and horns to the side. Caleb grunted as he felt the bull clench harder, then grinned as he shoved a second finger between the bull's teeth and pulled his head the other way.

"Nnnngh... yeah, fuck, you're so tight, you sexy little thing," Caleb growled, using his fingers to once more tug the bull's head to the side so he could move his lips right up against the smaller male's ears.

Caleb's thighs twitched. He dropped to his knees, making Panic cry out as he jostled and bounced over the impressively huge cock inside him. The tiger's immense white balls flattened between the tiled floor and the bull's rumpcheeks; Caleb fell forward in response, and Panic had to grab at the huge tiger's forearms as the big male's hips thrust him forward across the floor. Panic struggled to hold on as hot, steaming water and even hotter, muskier cum poured around him. His hips lifted, pulled off the ground by the log thrusting wildly between his cheeks, while his chest and head angled into the floor between Caleb's arms. The sabretooth's hips pistoned, rotating rapidly, driving the thickness forward and shoving Panic's shoulders into his forearms each time.

The intense humping continued as Caleb felt his arousal peaking. He shoved a paw down flat across Panic's backside, pinning the gasping bovine to the tiles as he leaned his chest up, crouching, wanting to watch his own megacock disappearing into the bull's hot and tight rump. He shoved forward as he looked down at his thickness, his abs, his pecs, and the backside of his newly shrunken, lean, sexy little boyfriend. The bull looked so cute and tight and squirmed so nicely that it was all the tiger could do to last as long as he did.

His claws popped out, pricking the bull in five separate places across his backside, as the enormous urethra swelled. Panic's muzzle opened wide, flat teeth showing as he MOOOOOOOOOO'd loud enough to draw a curious "What the fuck?" from outside the showers. His belly bulged, not just with the sabretooth tiger's awesome thickness, but the flood of seed, potent and thick, churning into his body and filling his belly. Caleb hooked a finger in the bull's muzzle as his cock fired off into the air, silencing the moaning male as he let out a surprised grunt instead.

"Mmmmhhh... now that's better," Caleb groaned. "Fuck, Panic... I may gotta hit that again."

"Finish... your first before... starting your... second!"

"Ah, you love it."

"Hurp!"

The fat, long tigerstock pistoned down, veins bulging as the massive length squelched inside the bull's already overflowing rump. A flood of thick white jizz rolled down the bull's thighs, draining away as the water washed around them. The shower couldn't stop the scent, though, and Panic's eyes closed, nostrils flaring, as he basked in the heat and musk generated by his boyfriend. At first, he didn't want to be the small one, but now...

*SMACK*

"Yeouch!"

"Heh heh... wake up, hot stuff. 'Bout to unload the second batch in your sexy rump."

The tiger's paws groped at Panic, turning him around, forcing him into any old position Caleb cared to try. He was so big and large now that it was easy to maneuver the much smaller bull around, flexing him like a plaything as he worked his cock to the hilt half a dozen times from half a different positions, each one ending with a firm, finger-led exploration of Panic's swollen belly.

The sabretooth growled, tail twitching, loving every moment of his new size. He was at least seven feet tall, and the new and improved Panic was no more than five. The cute bull still had a bit of definition, just a bit, enough to give him the right amount of clench and squeeze power to truly ride the huge tiger's massive unit.

Caleb fully intended to fuck his boyfriend in the showers until neither could move, but raised voices drew his attention. He turned around, carrying the impaled bull on his shaft with him, one paw resting on the ridge in Panic's stomach as he smiled at the newest arrivals in the shower. His fingers squeezed around the tip of his length right through Panic's belly before sliding upwards, ending with three plump tiger fingers going into the bull's moaning muzzle and spreading his cheeks.

"Oh, so that was you two we heard out there!" Simon said, dropping his head from up in the steam clouds near the ceiling to smile at the two. "Lookin' good, Panic."

"Blurgle."

"Hey, Caleb! Hope you don't mind, but I found some leftover protein shakes in your locker. Me and Simon split it. We'll hit you back for it later, okay?"

Bagna lifted a clear, transparent bottle up to his lips and the sabretooth's eyes widened as a familiar tingle rushed through his fur. Simon took the bottle from Bagna and drained the last of it before the two of them moved under the showers. The panther kept glancing over at Caleb as the sabretooth disentangled himself from the gasping, moaning bull, whose matted purple hair covered his closed eyes. The dragon looked over as well, a strange look appearing on his muzzle as he watched the tiger's enormous shaft flexed out from within the bull's body and smack against the wall, easily three-fourths as thick as the tiger's own hips and long enough to reach his shoulder.

"Uh... hey, Bagna," Simon grunted, nudging his boyfriend, who was sporting obvious wood while staring at Caleb.

"Yeah. Yeah, let's do it," Bagna groaned, one paw wrapping around the dragon's emerging maleness, the other sliding around his own. "Fuck, I need that cock..."

"Me too... please, fuck me, daddy," Simon gasped, eyes widening as he heard the words leaping from his muzzle. "No, I mean... I mean, drill me! Really pound my ass!"

Simon clasped his paws around his muzzle to stop himself begging, but the pearlescent blue dragon's thick, navy length was already fully hard and jutting lewdly in front of him, dripping with need. Bagna's paw stroked the huge, shivering length as Caleb's massive muzzle stretched into a smile, cock jerking and lifting, still fully hard and aroused despite what he'd just done to his moaning, groaning boyfriend spread across the tiles behind him.

Looks like there was more than one person who needed to learn about what it was like to be on the small side of things. Or in this case, he thought, wrapping a paw halfway around the base of his veiny, bright pink shaft, the big side.

The end
