"Where _is_he?" Ziggs poked his head out of the gym locker room, looking for the yordle that had signed the both of them up to be there. He always hated being alone in an unfamiliar place. "Of all the times for Rumble to be late..." A sigh escaped past his lips as he buried his face in his hands.

The entire concept of the iron pit was an entirely unknown concept to him until fairly recently when his yordle boyfriend suggested that the two of them ought to sign up. He barely had any idea what he'd gotten himself into, only now understanding the reality of the situation as it stared him in the face.

Grunts of exertion met his ears as he peaked around the corner, hopelessly lost in an unfamiliar environment. People were there, only sparsely, which quelled his anxiety a tad as it meant that there weren't too many people around to witness him struggling with concepts that they figured out ages ago. There were machines littered around the floor - and he knew machines - but they were alien to him, with parts that didn't make sense unless he saw someone using them. It was all so intimidating.

"Come on, come on, what the hell is taking him?" Ziggs grew antsy as he watched the locker room clock tick away, whole minutes passing by since he'd clothed himself in what Rumble had told him to wear. He felt ridiculous clad in his white muscle shirt that hung off of his body like he picked the wrong size, as well as baggy shorts that would've fallen to the ground had he not double-tied it. How was he supposed to be comfortable somewhere new to him when his clothing didn't even fit properly?

It got to the point where he could only entertain himself so much in the locker room before things rapidly grew tedious, with clockwatching in particular making him feel like time was flowing backwards. He'd had enough. "Alright, I can't wait anymore. He can come find me when he gets here."

Steeling his nerves, Ziggs took a deep breath and stepped out onto the gym floor, only to immediately regret it when he realized that he no longer was protected by the safety of the locker room. He felt vulnerable and exposed, even if there were no eyes on him.

And there was so much that he could do! Where would he even start? As intelligent as he was, he knew that he'd have issues trying to operate a lot of the machines due to them being built for humans, with his diminutive stature being wholly unfit to use them. Why did the other yordle think it was a good idea for them to go there?

That's when his gaze drifted over to the free weight racks, lined with increasingly larger dumbbells that ran down the length of the wall. Even if the operation of a machine eluded him, he at least knew how to use those.

Ziggs ambled over to the smallest available weights, only to recoil when he saw that the smallest on offer was a whole ten pounds. That's a lot for a yordle! Doubt crept back into his mind, but he pushed it aside as he grabbed the dumbbells, only to almost collapse to the ground as the weights dragged him down. Maybe this was a mistake after all.

With all the strength that his small body could muster, he pulled himself together enough to haul the weights to a free part of the matted floor in front of the wall-to-wall mirror, which he only did because he saw others doing the same thing. He honestly had no clue what he'd possibly get out of that - other than seeing himself fail - but if it was good enough for the humans, then he guessed that he'd do it too.

His first rep was a disaster; not even seconds into the exercise and he could barely lift the damn things. The one thing that they were made for, and he couldn't even do it! Should he give up right then and there? He wanted to, but Rumble would just trot him back out here anyway, rendering that option pointless. The only thing that he could do was try again.

It took a lot of effort that he felt across his body, but it paid off when he felt himself hoist them horizontally in line with his elbow. That wasn't where the humans stopped, but it was progress!

Still, even that little bit took a great deal out of him. He had no choice but to catch his breath before trying again. He'd been told that he was going to work up a sweat while he exercised there, but he didn't think that it'd start so soon! Was he really that out of shape? Sure, he had a gut because he loved his fork a little too much, but the sheer amount of walking around that he did should've helped condition him. This felt like a whole other beast.

Ziggs gave himself a few more seconds before he went at it again, gritting his teeth in frustration as he pushed the weights as far as his admittedly weak arms would let him. The tension caused by the exercise nearly made him black out, but it was all worth it in the end when he felt his hands reach his shoulders.

The weights then fell silently onto the matted floor. Exhaustion threatened to take him if he weren't so overcome with excitement. He did it, he really fucking did it! Yordles who trained for that kind of thing were really the only ones of his kind that could pull it off... until now. He conquered that weight, not anyone else. No one could take that away from him.

His success propelled him to try again. Gripping each of the weights, he hoisted them again, this time completing the rep for a second time, then a third. He was astounded, not only by the fact that he accomplished something very few of his kin could, but by the fact that he was doing it repeatedly. There really was merit to saying that things got easier the more that you did them. Wait, this was starting to feel too easy...

The lack of effort began to strike Ziggs as odd. Dumbbells that once pulled him to the ground as if attracted by magnets now felt like they were hollow. He stopped and looked at the weights in his hands, a quizzical expression contorting his face. He hadn't the foggiest idea why it happened, but he at least knew what to do when it happened.

He reracked his old weights and grabbed the next heaviest ones, pleased that they actually had some heft to them. The resistance was appreciated when he started lifting them again, returning back to his routine as if he never left off.

For the first time that day, he felt like he had a clue of what was going on. He felt like he belonged, even if he did the only thing that made sense to him. Rumble would arrive soon enough and help with the rest.

But that wasn't soon enough for Ziggs' liking. Like the first ones, these dumbbells suddenly lost all of their heaviness like someone had replaced the gym's equipment with kids' toys. He was dumbfounded. "What, again?" He mumbled under his breath, not wanting to attract attention to himself. Even one of those would've been impossible to move that morning, and now each arm was holding fifteen pounds as if he'd always been able to. Maybe this was what getting accustomed to exercise felt like.

Again, he moved up in weight, now holding weights twice as heavy as the ones when he started. He was certain that this would be it. Focus was squarely kept on them as he hoisted the weights in the air, trying to ascertain if it would happen for a third time. Luckily for him, the heft remained, much to his delight.

Finally, he could do like he was supposed to from the very beginning! The weight of the dumbbells was still apparent, making the action feel as rewarding as he was told it was going to be. Who knew that he'd actually be okay with this? Normally he had trouble trying something unfamiliar, but maybe this was the start of something good for him. He was moving the dumbbells around like all the humans were.

That was until these weights also stopped being a challenge. He couldn't believe it - this had now happened three out of three times. A slight twinge of panic shivered down his spine as his mind filled with doubt. Was that a normal occurrence? He looked at the humans also standing in front of the mirror, but he saw that they had all kept the same weights this entire time. Was he doing something wrong, or were they?

Absolutely weirded out, he went to rerack the dumbbells, but a glance at the lightest ones got him curious. He reached over to grab it, only to nearly fall on his ass when he picked it up because his body had braced for a weight that he didn't even feel anymore. Somehow, he went from not even being able to pick it up, to finding it less difficult, to now not even registering it as a problem anymore. He hurriedly placed it back in its slot. It was official; he was spooked.

Uneasiness washed over Ziggs like before, making him feel like it'd be in his best interest to stop and wait for his companion to actually get there. He was about to turn away until he spotted a peculiarity staring back at him in the mirror - his arms actually seemed to be more toned!

Muscle mass wasn't ever a thing that he'd thought about before, yet he couldn't deny its existence on his frame. It was as real as the rest of him, and he couldn't stop touching it. "Freaky." He giggled under his breath. For the first time in his life he actually had visible musculature, finally able to show it off when he flexed his arms.

The thought to ask Rumble about it occurred to him, only to remember that he was still alone for the time being. He looked back at the rack of weights and shrugged, thinking that he should just keep going as far as he could, only to recall the other yordle mentioning that they'd be doing a full-body workout. "Right, that's right." He tapped his chin in thought as he looked around the gym for his next possible exercise, but a lot of the other equipment seemed incredibly daunting to him.

And then he saw it - the Leg Press machine. Out of all the other apparatuses available for public use, that was the only one that immediately made sense to him. Anything simple to operate was his friend here.

Ziggs hesitated once he got to the machine, however, as he didn't properly gauge just how large it actually was. His eyes scanned all around the seat looking for a way to make it more compatible with his diminutive frame, eventually discovering all of the adjustment knobs and setting them to their lowest levels. It was all just enough.

He climbed onto the seat and adjusted himself, not entirely comfortable, but figuring that that was the point. Like the dumbbells, he started on the lowest setting and pushed himself. At the very least this felt like a more natural motion to him.

But it was tough, which was good! He knew that this was what a person was supposed to feel when they were exercising in this place. This was what he was meant to feel; what happened with the dumbbells had to have been just a fluke.

Unfortunately, he could only get a few reps in before his legs buckled and gave out. He panted from exertion, thighs burning from trying something new. The pain wasn't exactly what he wanted to feel, but it gave him peace of mind that he was fitting in along with everyone else. After a moment of rest, he began again, this time making it further than his last attempt.

Everything was good until the exact same sensation as the free weights popped up. How the hell did this seem light already?! He instantly stopped, scoffing when he looked at the comparatively heavy weight for his kind. He inherently knew that one's legs were stronger than their arms, but this was ridiculous!

Like before, Ziggs moved onto a heavier load, shoving the metal pin inside the magnetized weight. A quick test push felt alright to him, so he continued.

Up and down his seat moved along the track, his rhythmic breathing synced up with the motion. It was almost enough to make him sweat. The burning withered to a dull throb, actually feeling somewhat pleasurable compared to before. He understood why people took it upon themselves to workout.

And then it happened again. He couldn't believe it; barely a moment had gone by and the weight lost its resistance. This was maddening! He gripped his face in frustration, taking a deep breath to calm himself down. "This is..." He grunted, moving onto the next level. "This is kinda dumb." The numbers on the metal stared back at him so long as he looked at them. Rumble had mentioned that something called 'Beginner's Gains' was an actual thing, but were they this immediate for everyone?

A quick glance around showed that most people were still doing whatever activity that they were in the midst of when he started on this machine, signaling to him just how little time had really passed. The contrast felt weird to him, but he chalked it up to them having gone through this process already.

With a heaving grunt, he pushed his legs as hard as he could, his back plastered to the resilient fabric of the seat. The cadence of his movement lined back up with his breathing, matching his oscillations perfectly - breathe in at the peak, breathe out when at rest. It thrilled him to know that he figured this out all on his own.

His celebration came to an abrupt halt when - shock and awe - the weight felt effortless to move. By this point he was starting to think that there just _had_to be something wrong with the equipment. It would be difficult to prove with the dumbbells, but diagnosing the machine should be a cakewalk.

Ziggs hopped off of the seat and began snooping through the various mechanisms that made up the apparatus. His experience with various devices over the years led him to immediately be able to follow along with how this one was built... only to grow agitated when nothing out of the ordinary stuck out to him. He _knew_that it wasn't supposed to be easy after a few reps, so why was it? The soreness he felt during the exercise was certainly-

He audibly gasped when he felt his legs. No longer did he have his usually doughy thighs brought upon by years of his sedentary lifestyle, but instead he had rippling quads that bulged when he tensed them. And those calves of his... he had no idea that they could feel that solid. Maybe - just maybe - there wasn't anything wrong with the equipment at all.

His eyes already began looking for his next exercise, landing on one that he had to get up close to read the name of. "Single-Arm Cable Row. Huh, wonder what that means." He perused the interactive part of the mechanism, noting the singular handle attached to the cable affixed to the weights. The name instantly made sense. "Ah, it's mimicking rowing a boat. Got it."

The setup for this machine wasn't as intensive as the last, so Ziggs was able to hop right into the workout. Thankfully, the weight was already on the lightest bar, so he went ahead and tugged on the grip.

Gratefully, it felt difficult to yank, though he thoroughly studied the instructing diagrams pasted on the side of the machine's casing so he knew that the sensation didn't come from incorrect usage. That was exactly what he was looking for. He pulled again, now more confident in himself and able to bring the handle closer to his body.

After a while the same thing happened, however this time he was able to keep going by simply switching hands. It felt nice to be able to let his arm have a break while the other one worked. His motions were steady and calculated, although the eventual ease of his movements threw off his concentration entirely. Time to move up.

The more that Ziggs pulled, the more that he felt like an extension of the machine. He hadn't ever rowed a boat before, but to him it felt like he'd mastered it. In fairness, he figured that the real thing was significantly harder.

Eventually, the weight stopped being a challenge again, leading to swap hands again. Having to constantly shift the pin down a level was annoying, but he happened to overhear some people talking about doing more reps at a lower weight as part of their workout. He hadn't even considered that!

He put his plan into motion and pulled on the handle like he was trying to open his jammed junk drawer at home. His blood pumped with every tug, quickly feeling the weightlessness of the metal dawn on him, but he kept going. He yanked the grip with a determined look on his face, only for it to contort into a grimace as his pace crawled to a stop. That legitimately didn't work at all, much to his chagrin. It was time to add more weight. Again.

The act of putting the pin in the subsequent metal bar came naturally now to Ziggs, but he stopped himself when he got an idea. Instead of just going to the next level, he'd actually skip one. Maybe that would make a difference!

With renewed vigour, he pulled on the handle, satisfied when he struggled to move it. Now he was on the same page as the humans around him, who he was thankful had ignored him the entire time that he exercised. It felt really good that he was able to finally focus on his routine like he was meant to.

The whole situation felt silly to Ziggs. He had to chuckle when he realized that that was all that he actually needed to do this whole time. To think that all of his perturbed observations could've just been solved by-

He was fucking pulling the grip no problem again. His jaw dropped as his hand let the load back into its resting position, staring at his appendage in disbelief. Okay, he was back to having no idea what was going on.

Regardless, he felt like he had to balance his exertions out. His other hand grappled with the handle, pulling on it with little conviction as he knew that it'd be pointless eventually. How was he outmuscling literally every exercise that he performed? He was fine that his gym experience was actually going smoothly, but he just hated not knowing things, especially about his own body.

Annoyed and feeling like this whole thing was bizarrely pointless, Ziggs hopped off the seat. He felt like he didn't belong there, but not because things were too hard like what everyone else thought. There couldn't have been any other patron of this iron pit who experienced what he was going through; this place would have gone bankrupt ages ago if that was the case.

The need to stretch himself overcame him, causing him to place his hands on his sides as he bent slightly backwards. The motion felt good, but he couldn't stop his eyes from nearly bugging out of his skull when his hands inadvertently slipped up his torso.

To his absolute amazement, his back was wider, knowing that the muscles held in his grip in particular were his latissimus dorsi. "Holy shit!" He exclaimed to himself. "Is this a thing that actually happens to people?" Not once had he fathomed that the muscle group was something that could be worked on, but now he had all the evidence needed to convince himself. "Weird..."

Ziggs stopped to look at himself and realized just what kind of effect all of his exercising had on him, despite how paltry it was. Clothing that was once loose around his form now seemed like they fit him fairly well, only noticing then that the drawstring of his shorts had come undone without him realizing, yet they stayed in place. Clearly the service offered here was exceptional, if not entirely as advertised.

His newfound gains gave him an idea. With a spring in his step, he made his way back to the free weight rack, only to stop when he was about to pick up what was the next highest weight from his previous set. No, he'd go higher than that, he had to see if the previous results could be repeated. He was a scientist after all.

All of the other humans using the dumbbells were noticeably large for their species, hogging some of the weights in the middle of the rack. Ziggs didn't inherently mind that fact, but he wondered if that would give him trouble in his makeshift experiment. Only one way to find out.

While he wanted to jump to an impossible weight right off of the bat, he knew that he had to be able to lift it first. He got into position after selecting ones fifteen pounds heavier than the previous ones. Yep, they were heavy, alright. His face uncontrollably scrunched up as he attempted to heave them upwards. Okay, that had to have proved that he had his limits, right?

He finished the rep to his utter surprise. One moment he was striving to even move them from rest, and then the next they were at his shoulders. He shook his head - not good enough.

He bounded back and picked up heavier dumbbells, skipping another few in the process. It amused him that he even got this far considering the trouble that he had even starting; the first weight was a fraction of what he was holding now.

Ziggs clenched his teeth as he fought against gravity, barely budging the dumbbells as he snorted from his whole body tensing up. It seemed like this was the pair that would beat him, only for his arms to abruptly complete the rep out of seemingly nowhere. "Goddamn it..." He sighed. Oh well, next!

The entire act of picking up a new set of weights to exercise with only to return them because he outgrew them started becoming innate to him. Mental notes were made every time that his current dumbbells didn't reach his apparently lofty goals before going to get a new pair. His testing was the only thing that he paid attention to, not even catching the humans around him occasionally flicking their gaze to him as he dashed back and forth from the rack to his spot.

He let out a sigh of frustration when he was able to lift new weights again. He honestly couldn't believe it; literally every single weight ended up being hoisted without difficulty, regardless of how heavy it was. He was on the cusp of breaking three digits - completely unheard of for a yordle - and was just reaching the middle of the rack.

And then he hit a snag - the next section of dumbbells was gone, all pairs preoccupied by humans. He pursed his lips in irritation. Theoretically he could jump ahead to the next available one, but that was nearly a good hundred pounds ahead of what he just lifted. Maybe he'd have to come back to this later.

It was only as Ziggs was heading away from the rack did he notice what the increasingly heavier weights had done to him. He'd been so preoccupied on testing his limits that he didn't even watch himself in the mirror. His arms had positively exploded in size, appearing comparable to the bodybuilders honing their physiques. To say that he was stunned was an understatement.

Each flex of his limb doubled its size, causing his bicep to show-off its newly-gained split peak, and his tricep to form into the monstrously thick croissant-shape that the humans seemed to covet so much. But that wasn't all as he eventually recognized that his muscle shirt didn't fall straight down anymore. Indeed, his chest had ballooned outward, making the fabric contour around his pecs as if it were near skintight. "So weird..." He muttered. Yordles never got to this kind of size, and yet here he was.

But there was still more that he could do. He stopped checking himself out and looked around the room, trying to locate a place to test himself further. Something else, something else...

Out of the corner of his eye, he spotted something that he hadn't tried before. The dual handles and reclined seat gave him an idea of how the machine worked, but the label saying 'Chest Press' all but confirmed it.

Adjusting everything to his height went by smoothly for Ziggs, which prompted him to jump on and get right into it, only to stop and snicker when the weight left by the previous user was well below what his current capabilities were. "Oops." He quickly shifted the pin down several levels into something that felt appropriate. "Can't believe I forgot this."

If there was one thing that he was thankful for, it was the fact that there really wasn't any complex exercise in this place. The machine that he was using, in particular, was so incredibly simple that he belted out reps like it was nothing. Pretty much the only reason that he'd stop is because the weight grew too effortless to heave.

There wasn't a single other person like him in that establishment. Curious gazes were thrown his way, but Ziggs paid them no mind, however, he didn't even notice them anyway. All that mattered to him was his experiment, though the results remained increasingly inconclusive.

Every set was the same - a few reps, add weight, a few more reps, add more weight, a few more reps, add more weight... He just couldn't satisfy himself with a set load no matter how much he wanted it. It made him stop to ponder it.

And Ziggs did that until he realized that his pecs were now scant centimetres from his nose. It genuinely startled him, but a quick feel let him know that his eyes weren't playing tricks on him. What induced his curiosity further was the fact that they felt warm, obvious that the reason was because that muscle group was just exercised, but it led him to an important discovery. "Oh, that must be what those people I heard earlier talking meant by getting 'pumped'. Okay, that makes sense."

He was about to continue his workout when he realized that there was now an obstruction when he tried moving his head around. "Oh!" He prodded one of his traps with a finger, feeling the strength bundled up in the muscle mass. "Huh, I didn't even know these existed. You really do learn something every day."

Everything that he experienced was incredibly fascinating to him, and it made a little upset that he didn't even think to bring his journal to take notes. He could've taken measurements at every step, though that would've required him to bring a tape measure as well. And then there was the matter of somehow assessing his weight. It made sense to him that the locker room would be the best place to see one. Was there one when he was last there? There might've been, but he'd have to look just to be sure.

All of this contemplating blinded him to the fact that he couldn't see past his chest anymore. He didn't even register the fact at first, but it became apparent when he saw that he couldn't see his legs. "Oh yeah!" He quietly gasped. "We're supposed to be doing full-body. My legs are disproportionate right now." A quick confirmation pat with his hands supported the claim. Off to the Leg Press he went.

Besides growing muscle mass like his body was addicted to cultivating it, there was still one thing that struck Ziggs as odd about his time at the gym. "I just don't understand. Why did Rumble get us to pay for a monthly fee if working out is this easy? At this rate, I'll be maxed out on everything in an hour from now." He glanced back over to free weights and saw humans struggling to even hold dumbbells that he surpassed in seconds. It got him to cock his head in confusion. Getting big was that easy, right?

Eventually, he made it back to the Leg Press. Truth be told, he actually didn't mind this machine; it was the one that felt the most natural to him. And he was in luck, no one else had used it since he last did! It made it trivial to set up. Without thinking, he shoved the pin in several slots below where he last stopped and got down to work.

Like clockwork, the current weight stopped feeling challenging after a couple reps, prompting him to shove the pin in a lower level while staying stationary. The result was that it took him a ton of effort to push himself up once, only to decrease in difficulty with each subsequent thrust of his legs. It seemingly didn't matter what the load was anymore as the outcome remained the same.

More and more he intensified the load, only to overcome it no problem seconds later. It caused his legs to surge with bulk, quads bloating outwards, filling his once-baggy shorts with swollen heft that swallowed the space between his legs. Even his ass benefitted from the exertion, ballooning into globular cheeks that could easily crush some of the flimsier equipment with a single squeeze.

Ziggs' growth may have been lost on him, but it certainly wasn't lost on other patrons, who started crowding the growing yordle as he ran through reps like no other. Never before had they seen someone this adept at getting swole.

The lack of resistance elicited a grumble out of him, getting him to stop and lay his head back with his eyes closed. Maybe this was the entirely wrong place to be testing such a phenomenon. He was a chemist, so it stood to reason that this could be a chemical reaction that he could figure out back in his lab. Everything that zoomed through his mind didn't quite make sense, meaning that it'd have to take extensive research to be able to determine what, if anything, the probable-

Hey, Rumble still hadn't shown up yet!

The sudden realization got him to open his eyes, causing him to nearly jump out of the seat when he saw an army of others staring back at him. "Uh..." He had no clue that he'd amassed such an audience, especially not liking how a number of them were recording him on their phones. His heart was beating out of his titanically muscled chest. "Gotta go!" He thundered back to the locker room; his footfalls were as loud as his heart was in his ears.

Ziggs let his hands catch his head as he took a seat back on the wooden bench, ears swiveling to hear if anyone was following him. He thought that maybe Rumble wasn't coming after all, and that he'd be better off just leaving. He barely had time to open his locker before unfortunately hearing footsteps head into the room, but strangely only a single pair.

"Holy fuck." Rumble exclaimed, his fingers rubbing his eyes as he entered the locker room. "I am so sorry I'm late, Ziggs. Some asshat was fucking with me while I was trying to get here, and it took me way the hell too long to get him to stop." He chuckled under his breath. "Hope he likes that broken kneecap."

"Oh, there you are. Took you long enough." Ziggs laughed, shifting his body around so that he could see his boyfriend, only to stop when he saw the blue-furred yordle staring gobsmacked at him. "What?"

The words to describe the sight in front of Rumble just wouldn't come out, his brain failing him at every turn. He just couldn't comprehend how different his compatriot now looked. "What did you do?!" He sputtered in disbelief.

Ziggs stared at the other yordle in absolute bewilderment. "I... I did the thing we came here to do. I thought that was the point."

"Yeah, but-" The gym bag slung over Rumble's shoulder unceremoniously fell to the ground as his arms dropped to his sides. "I-I don't know how you did that..." It was only then that he was able to compose himself enough to form a coherent thought. "And you knew I was on my way; you could've just waited for me to get here."

"I actually did," Ziggs rubbed the back of his bull neck, feeling his swollen traps right underneath the base of his ears "but then I got bored after a few seconds and started lifting stuff."

The gears in Rumble's head appeared to be stuck, his brain failing to process the comment casually tossed out. "You got bored and then started lifting stuff..." It was all that was needed to fry his mind. "That... honestly doesn't sound like you at all."

Ziggs sighed, struggling to get his boyfriend to understand something that he felt was crystal clear. "Okay, I know that, but..." He gestured around to the empty locker room. "That was the whole reason we came here, right? What else was I supposed to do to pass the time?"

As much as he felt the need to fight, Rumble could accept his companion's account. "Alright, fair point." He took a seat next to the yordle behemoth. "Okay, explain to me what happened."

"Right, so..." Ziggs scratched his head, trying to remember his exact steps. "Alright, so I started with those dumbbells against the far wall, with the lightest one specifically."

"Yes, because that's heavy for us." Rumble nodded along. "Go on."

Ziggs eyes lit up. "Yeah, but then they weren't!"

A wave of puzzlement contorted Rumble's expression. "Excuse me?"

"Yeah, literally that. I'm not lying!" Ziggs could feel himself get heated trying in vain to justify his situation.

"So just..." Rumble palmed his face. "Out of nowhere you could just lift it."

"Correct."

The answer left Rumble speechless. "But you..." He blinked in confusion. "So that was it? You were somehow strong enough to lift it?"

Ziggs rolled his eyes; he had to speed this up. "Alright, long story short, literally any exercise I tried became trivial after getting through it once. I kept upping the weight to see if I actually had limits, and then suddenly I was huge."

"Alright, yeah, that makes perfect sense." Rumble buried his head in his hands. "Did nobody else say anything?"

"I honestly didn't even pay the other patrons any mind, I kinda just went around and tried a bunch of exercises to see what I liked." Ziggs couldn't stop himself from laughing at the ridiculous nature of his predicament. "And then at some point all these people started crowding around me. I didn't like the attention, so I came back to the locker room."

"Yeah, for good reason. Some of them might not have been here all that long, but others have been working out for a few years and have maybe put on fifty pounds of muscle if they're dedicated enough." Rumble felt himself going mad with a bewildered frenzy. "You surpassed literally every single person in the building without trying. They were looking at you because what you did was impossible!"

Now it was Ziggs' turn to lose his mind. "Is it really?" Was it really impossible if he accomplished it?

"Seriously?! What do you mean, 'is it really'?!" The reality of this being a fever dream seemed increasingly more probable to Rumble. "The whole purpose of a gym is to gradually hone your body over an extended period of time through constant, committed effort. Making gains that quickly is genuinely unheard of for anybody!"

"How was I supposed to know any of that?! I haven't ever stepped into a place like this before, let alone hearing about it until literally a week ago when you said that we should go sign up at this one." Ziggs vigourously rubbed the sides of his face. "And I remember asking what the point is, with you telling me, 'You go there to exercise and maybe gain muscle if you want to'." His energy dedicated to explaining his situation had been utterly spent. "That's all you gave me, dude!"

A long groan built up in Rumble's throat before he let it out with a sigh. "Alright, I kinda dropped the ball on that one then. That's on me."

"I honestly didn't know it wasn't supposed to be this easy. I kinda thought everyone else was just really bad at it." Ziggs stared at the floor, only to forget that his pecs obscured everything below them.

As much sense as he could pull from the yordle hunk's story, there was still one thing that still stuck out to Rumble. "So, it just never occurred to you how weird your situation is?" He stifled a chuckle.

"If I knew what was going on, I probably would've reacted way differently." Ziggs scoffed. "Maybe I'd have stopped when it took moments for me to eclipse the very first weights that I tried, or maybe I'd still be on the gym floor working out right now. I don't know."

Rumble's snickering evolved into mirthful laughter at the absurdity of everything that he'd heard thus far. "You mean to tell me that you never noticed you got more swole than the most passionate of gym rats in..." He flicked his gaze over to the clock, only to do a double take when he saw how little time had passed since he planned to be there in the first place. "Fifteen fucking minutes, are you kidding me?!"

Ziggs rubbed his chin. "Huh, has it really been that long already?"

"What the fuck do you mean 'that long'?!" Rumble for sure thought he'd end up going crazy. "I was planning on us being here for an hour and a half!"

"I mean..." Ziggs cocked a brow. "Could we not still do that?"

Rumble looked ready to give up. "I genuinely don't even know anymore." He looked over at his studly compatriot, eying up that swollen physique. "So, what are you gonna do now?"

"Uh, not sure, to be honest." Ziggs pursed his lips. "I guess since you think I've already done so much, I'll just get my stuff so I can go home and bathe myself."

"Oh, you don't actually have to go to all that trouble. There are showers past the last row of lockers." Rumble mentioned as he removed his clothes, rummaging around his bag for his gym attire. "That's why I packed your shower stuff in your bag."

Ziggs instantly turned his head to look, only then realizing that he needed to rotate his entire body now with all that beef enveloping his neck. "Oh, I didn't even notice!" He side-eyed the smaller yordle. "Uh, are you gonna join me?"

Unbeknownst to Ziggs, Rumble thought that the offer was incredibly tempting. Alas, he was there with a purpose. "I was actually gonna go out and do some stuff first. You know, build up a sweat so I have a reason to wash off."

For the first time that day, Ziggs let loose a smile that stretched as wide as his mouth could go. "Oh, is that all you need?" With a speed that belied his size, he grabbed his naked compatriot and shoved him against his bulging form. The agitation caused by the abrupt presence of the other yordle released the built-up musk that accumulated throughout his admittedly brief workout. It was an alluring aroma of masculinity that he swore smelled better now than when he was smaller. "There, now you're sweaty!" He let his boyfriend go with a giggle.

If Rumble could look more unimpressed, he would. "Why must you do these things to me?" He did his best to hide the boner that he got from being pressed against the beefcake musky bulk.

Ziggs chuckled to himself as he carefully peeled the strained muscle shirt off of his brawny frame. "Because I know they bug you." A quick side-eye at the pouting yordle revealed the raging stiffy that the blue-furred brat tried to keep hidden. "See something you like?"

Rumble, snotty as ever, refused to acknowledge the larger yordle's teasing. "I always like you without your clothes on."

Ziggs knew for certain that the yordle shrimp was cornered. "And what about now?" With some split-second planning due to never having done this sort of thing before, he pulled his sumptuous arms as much as he could against his sides and flexed, protruding his pecs out to the point where he could almost casually lick them.

A quick glance in his boyfriend's direction sealed his doom. Unfortunately for Rumble, the cat was entirely out of the bag now, with his turgid member now pointing directly at the hulking yordle. He might as well fess up now. "Why do you think I got us to come here in the first place?" Rumble shot Ziggs a knowing look.

Ziggs instantly dropped his pose upon hearing that. "Hold on, is that actually why we're here now?!"

"I kinda think the aesthetic is hot, so I thought we'd give it a try and see what happens." Rumble shrugged, blushing as he revealed his hidden agenda. "I love you, so you with a little bit of muscle mass would've just more of something I love."

"So, what about me now?" Ziggs groped one of his plump pectorals, his tongue cheekily sticking out of his mouth.

"You know how they always say that too much of a good thing is bad for you?" Rumble's inability to control his excitement was evident by the goofy grin plastered onto his face. "I think I'm willing to make an exception to that in this case." His plan was an unbelievable success, somehow. He was ready to gloat to himself about how much of a genius he was, only for the sudden appearance of the behemoth's monstrous cock to completely overshadow anything else that he was thinking about. "Holy shit, how fucking big are you?!"

Ziggs quirked a brow as he dropped his stretched gym shorts on the bench, not understanding what the other yordle was getting at until he felt his swollen yordlehood slap around his domed musclegut. "Oh dude, I can't believe I actually never noticed that." While he couldn't see it, he could certainly feel it. He possessed a thick hog of a fuckstick, a testament to the girthy meatlog that he always had, and a welcome complement to his current bloated musculature. "Nice!"

"Oh, my fuck, that thing is gonna split me in half, dude..." Rumble whimpered when he saw the throbbing endowment spurt a dollop of pre from the tip, coaxing his eyes to follow the bulging cumpipe down to the herculean yordle's kneeslapper testosterone factories. They gurgled fresh seed far faster than dozens of his kind could accomplish in the same amount of time.

"Well, we'll just have to take things slow to start if we wanna do that." Ziggs wrapped his arm around the smaller yordle, pulling his boyfriend in close. He could feel his companion nuzzle his nose into his musky fur, sighing in contentment.

Rumble momentarily lost himself in the heavenly scent, only snapping back to reality when he heard the shower curtain close behind him. "Aw, fuck." He groaned. "I forgot my bodywash back in my bag."

"Eh, don't worry. I got my stuff here." Ziggs dropped his toiletries onto the provided shelf before turning his full attention to his blue-furred boyfriend. "You know, I haven't gotten to do this yet today." He giggled before pulling the smaller yordle into a kiss, a forceful, yet passionate embrace that melted away all the stress that had built up while being alone.

Rumble moaned into the kiss, his dick pulsating with need against the brawny yordle hardbody that he was smooshed against. He was getting mashed like a toy would, but he loved every moment of it. "God, I fucking needed that too." He buried his nose into his boyfriend's titanic trap, deeply inhaling the ambrosial scent like it was about to disappear forever. "And I just... I don't even care how this happened, man, I'm totally into all this."

"Hey, this works for me too. Now I'm a grower and a shower!" Ziggs laughed as his shaft belched forth a glob of preseed, smearing against their sweaty forms. He was achingly hard and raring to fuck, but even just being around his boyfriend brought a ton of much-needed relief washing over him.

Rumble didn't have to see the mammothian yordle's prick to know what happened. It electrified his nervous system, shooting impulses that overstimulated his nerves. He wanted it in him so bad, and he only just thought of a way to achieve that in spite of their size difference. "You know what, I think I'll try the way that doesn't immediately kill me first." He gingerly let himself down until he was flat on his feet, then traced a finger up the other yordle's leviathan fucklog and ending with a hand pressed in the centre of the hulk's chest. "Okay, back up, lover boy."

"Yes sir!" Ziggs didn't even care to pay attention to his surroundings as his mountainous back slammed against the concrete wall. He was too lust-drunk to care what happened next.

The sight of the stud's ginormous salami caused Rumble to lick his lips in anticipation. "God, it's so fucking huge!" The embarrassingly whorish arousal coursing through his veins got him to uncontrollably tongue his way down the throbbing shaft to those palpitating orbs, roaring with ecstasy as they audibly churned new yordlebatter from his slight touch alone.

The act nearly got Ziggs to involuntarily moan aloud, his hand cupped over his muzzle being the only thing from giving away what the two of them were up to. He giggled into his hand from the thought of someone catching them like that. "God, you're gonna make me blow already!"

"Oh no, not now, you're not!" Rumble needed both hands to grip the tumescent cock, the mere idea that one wasn't enough making him weak in the knees despite already kneeling down. He shoved his tongue along the sensitive glans, forcing it beneath the bunched-up foreskin and tasting the salty residue left by it being smashed against those sweaty balls.

The act elicited a spontaneous groan from Ziggs, who tensed his entire body from the immense stimulation. "I swear, you're actually fucking trying now!"

A mischievous smirk wormed its way across Rumble's face. "If you're gonna explode, then I'm getting it all in me!" He lowly chuckled as he gave those kneeknockers a hearty squeeze.

Ziggs gasped out loud, his crotch rocket shooting forward involuntarily. "Nope, I'm not gonna last." He tried his absolute damndest to edge himself as long as he could, but he hadn't had anywhere near enough time to acclimate to his engorged physique.

"Oh, that's my cue!" Rumble impishly laughed, doing his best to fit his mouth around the tasty pillar. The fact that he was nowhere near shoving it all in his mouth was astonishing, the feeling unlike anything he'd ever experienced before. He wouldn't be able to do much if he could provide a proper blowjob, but he did just discover his boyfriend's new 'release' button.

"Fuck." Ziggs cursed through gritted teeth, eyes screwing shut when he felt both of his orbs manhandled by his demon of a boyfriend. The way the little bastard always knew how to always set him off was unparalleled, but it caused their sex life to never dull. Still, his new body was entirely overly sensitive, so even just that small act was enough to set him off. With an unstifled moan, he unleashed his torrent of spunk right into the awaiting maw of his lover.

Rumble's eyes bulged as wide as saucers as he felt the cascade of cum force its way down his throat. He'd learned ideal breathing techniques having been in this position many times in the past, but this went well beyond his years of practice. Nevertheless, he was committed to not even letting a single drop touch the ground.

The tumultuous flood of potent cum gushing from his cocktip left him under the control of his raging libido. He wanted nothing more than to completely empty his balls into the other yordle, with a small part of his brain questioning if that was even possible. But it wasn't like he could stop to check, and it certainly wasn't like his boyfriend cared to do anything else but personally test their limits as a couple himself.

Untold buckets of rich, creamy seed blasted down Rumble's greedy gullet, rolling his eyes to the back of his head in pleasure. He'd had a dream like this once or twice, but he didn't even have to pinch himself to know that this was completely real. He reveled in the way that the behemoth's hand held his head in place, mostly doing his job for him as he continued swallowing rope after rope of cum. It took what felt like ages for the flow to slow down, but the experience was wholly worth it and he couldn't wait to try it again.

Ziggs sputtered as he shot the last remnants of his load into his lover before feeling his knees buckle, making him slide down the wall as a panting mess. His sweat-matted fur only grew moreso, intensifying his scent so that the two of them didn't have to do anything to smell him. The fiery love for his boyfriend caused him to involuntarily lift the cum-bloated yordle against him for another ardent kiss.

Rumble leaned into the embrace with his own force in spite of his delirious state. While his beefcake of a lover completely spent himself with shooting out the biggest orgasm in their kind's history, the act of forcing all of that jizz into his gut made him go half-lidded on his own. He rubbed his bulging middle, wondering what he could do to shrink it to a more manageable size, before remembering that they were still at a gym with all the time in the world to work it off. That's what he was planning on doing had a warmth not awakened in his core and radiated outwards.

Ziggs had trouble keeping his eyes open, but he didn't need them to know that something was going on with his blue-furred boyfriend. He unloaded litres of cum into the smaller yordle, yes, but his lover began feeling heavy in a totally different way. It took a second for him to collect his bearings to understand what was really going on - Rumble was growing, just like he had earlier.

Rumble himself barely had an inkling of what was happening to him while his body engorged with diamond-hard muscle mass. All over he could feel it swelling beneath his hide, the muscle fibres tearing and repairing themselves in an instant, ballooning him as if his body was connected to an electric air compressor. He bloated out huge, giving him the strength to regain enough consciousness to enjoy the sensation of bulking up without doing anything. How he fucking loved this! "Holy shit, I'm-" His shaft pulsed to life in an instant, now magnitudes larger than before, pencil-thick veins snaking along it. "I'm as big as you are!"

"Woah, how did you-" Ziggs only just regained enough alertness to register that his formerly-tiny boyfriend was now a hugemongous behemoth like him. "Did I somehow..." His mind swam with all sorts of thoughts, both horny and rational as he attempted to piece together the other stud's rapid ascension. "I-I don't know... is this a yordle thing?"

"It's gotta be a yordle thing, dude." Rumble chuckled as he pressed his fingers into the pecs situated right in front of his nose, not even able to make a dent. "Oh, this is weird, but so cool!" He mashed his sweaty chest against the other yordle's swollen pecs. "We're the biggest fucking studs in the place."

Ziggs let loose another moan as his boyfriend assaulted his tense form with all that delicious bulk. "God, this is what it feels like." He uncontrollably launched his hands at the blue-furred menace, feeling just how swollen the gorgeous hulk had become. "I just..."

Rumble's libido forced him to lasciviously mash his lips against his companion's, their tongue's dancing in unison with one another. It was tough with their hundreds of pounds of yordle beef, but they made it work. "Oh, I wanna love you so bad."

"Please... please do." Ziggs huffed, need building up in his soul. He worked with the other yordle to flip himself over, his lower half erupting in the urge to be bred so bad that his pucker winked in anticipation for his bulky Adonis of a boyfriend to stuff him full of throbbing fuckmeat.

"Ziggs, your ass." Rumble moaned like he was in heat. "It's one of the hottest fucking things I've ever seen! I hope mine looks half as good as yours." He gripped those dimpled globes, unable to even cup a third of them with a hand. It was big like the rest of him, and big was good. He hungrily dove his face between those tan-furred ass cheeks, voraciously shoving his tongue in and out of the hole.

Ziggs had no resolve left to keep himself propped up with his arms, letting his body naturally push his muscled ass up towards his tonguefucking lover. The moment when it got removed felt like several eternities as arousal screamed for him to be fucked, only to be replaced with euphoric bliss when he sensed the tip of the hunk's fat cock between his cheeks.

Wordlessly, Rumble smeared his precum around the already open hole, slicking the entrance enough to effortlessly shove his hog right in. It felt sensational to plug his horny boyfriend, and just as good to feel those inner walls clench down on his pulsating length. No time at all was taken before he was balls deep, ready to fuck the other mammothian yordle like rabbits.

The anal invasion carried out acted as if it forced his innermost thoughts out into the real world. "Fuck me..." He groaned under his breath. The sensation of prodigious pectoral beef on his brawny back was surreal, like he was imagining the whole thing, but every thrust into his gaping asshole immediately told him that this was actually happening. He relished being fucked as it'd never been this good in his life.

The love that Rumble had for his boyfriend poured forth in his humping, pistoning into the muscle monster's anal cavity in a frenzied, but steady, rhythm. He wanted nothing more than to make the other yordle feel good, like he did when he sucked him off. Every bounce of his pelvis against those muscly glutes added to his horniness, making him just as needy for orgasm as the man bottoming for him.

Ziggs had a hard time keeping focus as his boyfriend's love muscle slammed into his hungry hole. His eyes fluttered profusely from the filling he got, the engorged shaft jackhammering his prostate flat despite how swollen it got. He wanted the blue-furred beefcake to fuck him faster and harder, showing him how strong he really is!

Rumble's pendulous cum tanks slammed against his boyfriend's own, also contributing to pushing him over the edge, though being far more successful in the endeavour. It sloshed his seed around as more produced with each thrust, eventually forcing his grip on his lover to tighten. He wound his arms as far as they would go around the tan-furred hulk's titanic torso and bucked his hips a few more times until sealing the hole entirely by forcing his crotch flush with the other man's flexing ass.

Untold amounts of yordlebatter flooded Ziggs' bowels, his inner cavity painted by the pearlescent cum. His head drooped to the floor as pleasure overwhelmed his system. He wanted everything that the handsome stud could give, so he clamped down on that rod as hard as he possibly could. He wanted those fucking balls drained into him and wouldn't stop until they were empty.

Being this big meant the biggest fucking loads imaginable spewed from his shaft, but Rumble also noticed that all traces of energy went along with it. The more that he fired his ropes of seed, the more that he felt his grasp weaken, causing him to collapse on top of his swollen behemoth of a boyfriend. But regardless of that fact, this was him now and forever, and he never wanted to go back.

The pair of yordles crumpled into a sweaty heap, gasping for breath. Ziggs had splayed out on the padded shower floor, but Rumble was on cloud nine with his nose firmly between those embiggened pecs. The intense, masculine essence was contradictingly soothing, washing over his hulking physique like a warm blanket. It amused him that his boyfriend could make him feel good without even trying.

Eventually the pair of lovers came to enough to recall where they were, finally ready to take that shower. They didn't get there quite yet as making out with each other took top priority. They now had access to the other behemoth's bloated musculature, with Ziggs taking special interest in Rumble's ass. He'd make sure to ravage that tight hole sometime later.

Their lovemaking didn't stop when the water got turned on, though the two lovebirds were so preoccupied with one another that they couldn't remember who activated the showerhead. Not that it mattered since it gave them another opportunity to profess their love for one another by thoroughly washing their boyfriend's body, carefully combing their soapy hands through the fur to ensure that all dirt and grime was gone. No other reason, of course.

But then, all good things must come to an end. Once actually clean, the shower was shut off and the two mass monsters ambled their dripping heft back to their lockers, amused that they still had the whole room to themselves. They could make a hell of a surprise for the humans if they wanted to.

Rumble barely got started toweling off before stopping to fondle himself. "Holy fuck. All of this..." He gave his bicep a good, long lick, the act of self-worship chubbing him up full again. "This is just beyond my wildest dreams!"

Ziggs instinctively did the same, only to realize that his pecs had _absolutely_ballooned even closer to his nose, almost casually touching it now! "Wow, I think we got even bigger."

"Yeah, we got really pumped up!" Rumble dug his nose into his chest meat, inhaling the musk already produced despite just scrubbing the furry forest in his pec valley. "I kinda don't even know what to do now. We've both barely been here today, and yet we look like we've lived here our entire lives."

A wry smirk twisted Ziggs' mouth. "I mean, we could go back out there." His own shaft throbbed to life like downtime was a thing of the past. "I didn't max anything out when I was using the equipment, so I think we can still keep going even though we got bigger."

Rumble let out a devilish laugh, not even considering that to be an option. "You really want to?"

"I mean, our afternoon is free and we're already here." He squeezed around the bench to stand pec-to-pec with his boyfriend. "Fuck it, you know?"

Rumble's urge to cum rose by leaps and bounds in an instant. "I wonder how long our clothes will last at this rate." He shoved his meatlog into his shorts, the tip having no choice but to sneak past the bottom hem. With how strained the material was, his erection left literally nothing to the imagination.

"I wonder if they'll let us cancel our subscriptions after barely using them. I overheard some people talking about how hard that is earlier." Ziggs wedged himself back into his muscle shirt, though it started living up to its name by showcasing the gargantuan bulk that he possessed. His nipples hung in the open air while pointing straight down due to the tremendous amount of beef on his chest, while his colossal traps forced the thinning straps to raise off of his flesh entirely, displaying a fairly large triangle demonstrating how much muscle mass was truly crammed onto his body. The shirt couldn't even cover up his tortoiseshell of a gut anymore!

Rumble fared no better with his top, the T-shirt instantly looking like it was at its breaking point, ready to shred into ribbons with an errant flex. "They better. All the equipment here will be useless to us in no time flat!"

Ziggs gave his beefcake lover a pat on his boulder shoulder while heartily laughing. "We can just start lifting the equipment itself if they don't. It won't be _our_fault that they want us to continue using their services, so we'll just have to keep going until there's literally nothing left for us to lift!"

"Now _that's_getting our money's worth!" A sudden rip caught his attention, noticing a tear in the sleeve of his shirt as it failed to contain all of its beef. He experimentally flexed as far as it would go, doubling the size of the muscles, but splitting the sleeve all the way to the seam at the shoulder. He shot the tan-furred yordle a salacious glance. "Wait till the guys back home get a look at us!"
