Out in the woods outside of Motostoke, Lake paused to take a break and drink from his canteen. The shiny obstagoon stood fairly average height for his kind, though he did appear to be rather scrawny. The dark type's family had moved to Sinnoh a generation or so back, so the chance to live in Galar was a way of reconnecting with the homeland he'd never known.

Of course, Lake hadn't accounted for how much larger the other obstagoons would be. Being shiny presented a whole other set of issues, making him stick out amongst dark types with his vibrant coloration.

As the wiry male thought on this, he heard a bass grunt of exertion. Lake perked up, setting his canteen back to hang at his side, before heading up the trail towards the sound. The grunts continued at regular intervals, growing louder as he went.

When Lake reached the edge of the clearing up ahead, he froze. Off the side of the path, in the large open area, was a series of felled logs, clearly tall trees from this very forest. What froze the obstagoon in place was what was amongst them.

On adjacent logs to one another a stoutland and an urshifu were lifting immense stone weights. Each was lying in such a way that their heads were angled towards their observer. From that angle, Lake could clearly see both muscular pokémon sported a large ball belly, rising up even further than their mighty pecs swelled each time they completed a fly with their boulders.

The scrawny obstagoon stared in awe. It was one thing to see an urshifu performing such feats of strength, they were known for it! But the stoutland was a normal type, keeping up rep by rep with the fighting type.

Then, both massive pokémon dropped their weights at the same time. Lake felt as though his knees might buckle from the tremor that sent through the earth, even as far as he was. His eyes didn't leave the pair, however, darting from one to the other as they slowly sat up on the large logs, looking to each other without a word.

The urshifu tilted his head towards the far more open space between the logs and the path. He pivoted with his thighs spread and got onto his feet. As his legs came into view from behind his broad belly, Lake saw that the bear was also a hyper. Laden with orbs that mirrored the shape of his taut muscle gut, the fighting type's scrotum hung past his knees as he casually strode into the makeshift sparring ground.

When the stoutland stood off of his log, Lake was shocked to find that the normal type matched his rival in this respect as well. Enormous testes jostling one another in a way that made the dark type in the shadows wonder how either of them walked so easily.

The pair of hypers squared off against one another, taking up martial arts stances. Lake blinked, and they were on each other. The powerful pokémon lunged and struck, spun and kicked, not seeming one bit encumbered by their round bellies or prodigious genitalia.

Then, the urshifu proved its specialization. In a move Lake had only seen in tournaments he'd watched on television, the bear pokémon performed the water sub-typing specialty of his species: Rapid Strikes.

The stoutland tanked the hit, his belly absorbing the brunt of the flurry of blows. Amidst his heavy facial fur, his cheeks appeared to puff out, before contracting down as though he swallowed a mouthful of air. He stood steady, not showing a sign that he was close to fainting after that potent attack.

As Lake watched, the pair's sparring abruptly halted. They each bowed to one another until their round bellies pressed against their thighs, before standing again.

In a flicker of rapid movement, the urshifu departed the clearing, heading to parts unknown.

It was as though a spell had been lifted, and the obstagoon found himself able to walk again. First, Lake walked towards the logs, along the edge of the clearing. He came close and stared at the boulder that the stoutland had lifted with one hand. It was taller than he was!

A low sloshing sound followed by the sound of grass crunching alerted the dark type to the approach of the remaining rival. The stoutland was walking straight for Lake, an amicable smile on his face. He raised one arm. "Sorry if my friend and I were making too much noise. The gym in Motostoke doesn't have the kind of weights we need."

Lake swallowed, staring up at the enormous canine. "I... I've never seen anyone as strong as you before... you took every blow of Rapid Strikes without even flinching!"

The muscular pokémon let out a bass chuckle, slapping his gut with a palm. "If you can prepare for it you can withstand most blows."

"And these weights... You aren't even sweaty!" The obstagoon gushed, marveling at that kind of strength.

"I'm Baltic." The stoutland derailed Lake's waterfall of praise with his name, smiling. "Like strong guys, huh?"

"I'm Lake. I..." He paused as he tried to think of what to say next. "Well, I've never really been that strong. Got most of my levels in college instead of getting in scraps." The obstagoon smiled dopily, his blue tongue hanging out the corner of his mouth. He realized it was hanging out and drew it back in, blushing.

"That's because you didn't have someone to unlock your potential, Lake." Baltic rumbled, planting his fists on his hips. As he swiveled his pelvis to stand up straight, his prodigious loins let out another bass slosh. "You're fully evolved! You've got plenty of power locked away in you. Just need to hone it and find a way to bring it to the surface."

The shiny stared, wide eyed. "You... you really mean... But all the other 'goons say it'd be a waste for me to even go to the gym."

Baltic growled a bit, squinting. "Tell you what, Lake. I'll train you. I'll show you that all that dedication you have in you can make you as strong in body as you are in will."

"But... you only just met me!" Lake stared up at the stoutland in astonishment.

"I see a lot of potential in ya." The massive normal type rumbled. "Now, I'm gonna get to cleaning up from this work out. If you want to go through with the training, meet me at the gym in Motostoke. Tell 'em you're with me."

The obstagoon nodded slowly, watching as Baltic turned away with a sloshing sound to heft up the mighty boulder with one hand, and then scoop the immense tree log under the other arm.

Lake arrived at the Motostoke gym, fussing with the blue fluff on his shoulder anxiously. He idly wished he had the tail he had back when he was still a zigzagoon, but he'd spent more of his life without it than with it at this point. The obstagoon looked around and spotted a waving hand attached to an enormous arm quickly enough.

Baltic was standing behind the counter at a bar off to one side of the lobby area. The stoutland lowered his hand once he was sure Lake had seen him waving, returning to piling berries into the jug of a blender.

When the shiny pokémon arrived at the bar, he looked over the large jug as the larger male turned it on, sending the tiny fruit spinning and slashing into the blades until they were a uniform texture. "Is it okay to eat right before working out?"

The stoutland finished blending and poured a tall glass from the blender. "This first day is about prepping your body for the training. Gotta get all the nutrients into you and build up some reserves for you to draw from."

Lake nodded, sitting on one of the stools as he watched the much larger pokémon loading up a mix of berries and vitamin tabs into the next jug.

While the contents blended, the stoutland got a fresh jug and began to pour a mixture of vitamins and candy together, before adding yogurt on top.

"Candy?" The obstagoon asked, as Baltic changed jugs and continued blending.

Pouring the berry and vitamin mixture into another tall glass, the muscular pokémon chuckled. "Building up reserves. It's concentrated experience, as well." He took a sprig of mint from a potted plant at the back of the smoothie bar and dropped it into the bottom of the next jug, before just dumping candy into it until it was full. Every time he took a step, Lake could hear the low, fluid sloshing, as if asserting the hyper's masculinity even when his immense endowment wasn't in sight. He reached under the counter and produced a bottle of miltank milk, pouring that over the candy until it filled the space between them to three quarters up the jug.

Lake stared, swallowing nervously as the blender was changed out again, a third tall glass poured and set in front of him, and that last mass of candy was set to the spinning blade.

Baltic finally poured the last glass, setting it at the end of the line. "Drink up. Start from the berries."

Speechless, the obstagoon did as he was instructed. The first smoothie was more a pulpy juice than he'd expected, but it tasted good enough. Lake exhaled through his nose as he drained the last of the glass, stifling a belch into his cheeks through pursed lips. He felt full just from that, but Baltic knew what he was doing.

Grasping the next glass, Lake perked as he felt his tiredness and general fatigue from hiking the previous day fading. The berries were doing their work quickly, it seemed. The obstagoon started to drink the berry and vitamin mixture, placing his free claw against his slender midsection. Though he didn't feel as though he was getting overfull, the surface of his stomach began to curve against his claws.

As he finished the second blend, the dark type felt a bit more alert. Like his physical drain before had faded, the weight that made his mind sluggish sloughed off in turn. As such he was acutely aware that his stomach was continuing to grow slightly even as he had stopped adding to its contents. Lake looked down at his stomach as it gurgled, making room for the next smoothie by turning the berries to a layer of plumpness.

Baltic cleared his throat and tilted his head towards the third glass.

Cowed, Lake nodded and took the first smoothie to include candies. The scent was sweet, with a hint of bitterness from the mass of vitamins that had been pulverized with them. The obstagoon closed his eyes and began to chug. Almost as soon as the mixture struck the inner lining of his stomach, the shiny felt a rush of warmth surging through his body.

At the same time, the curve of his stomach swelled out faster than from the berries, pressing into Lake's claws and forcing them apart. As the dark type finished that smoothie, he shuddered, before grasping at the last without needing to be prompted. This one smelled faintly of mint, but mostly of an overpowering sweetness.

Lake drank, chugging hard. The flavor was beyond sweet. It was more intense than if he'd merely dumped sugar onto his tongue straight. At the same time, the rush of strength he felt surging through his body doubled in intensity with the higher concentrate of candies. When the obstagoon finished the last glass, he felt properly full, stifling a belch with the opening of the tall glass, which just blew the overly sugary scent back over his face, with a hint of mint.

Baltic chuckled, walking around the bar with a heavy series of sloshes. "There ya go. Drank those like a champ."

Thoughtlessly, the obstagoon shifted on the stool to stand up, only to find his balance had shifted significantly. Exacerbating the problem, the contents of his stomach sloshed towards the direction he leaned! Lake threw his arms out and grabbed onto the side of the bar for support.

The stoutland grasped his pupil's other claw. "Steady there... You're a bit top-heavy still. Next thing should fix that."

Leaning into that grip and holding his bloated belly to keep it from swaying too much, the obstagoon bit his lip. His stomach was nearly as loud as Baltic's testes from how much smoothie was still in his gut. Lake followed the muscular pokémon to a large machine taking up the wall of the lobby. At the top of the machine was a label: 'Mr. Hyper'. The dark type looked over the device, seeing that there was a metallic door with a slot next to it.

Baltic used his free hand to open the door. "Now sit down in there and relax."

"What's it for?" Lake tilted his head, looking at the padded seat on the other side of the doorway.

The muscular stoutland smiled. "This machine unlocks a pokémon's potential. If I trained you without this, you'd get fit, certainly, but you'd plateau in your progress over and over again." Baltic nodded firmly. "A lot of unnecessary struggle to unlock one IV at a time, when we have the means to do them all at once. It's not going to do the training for you, though. You still have to do the work."

Nodding, though not really understanding, the obstagoon carefully stepped inside the machine and turned around. Lake sat down with a loud slosh, feeling the sculpt of the padded seat forcing his thighs to spread out wide. His bloated belly sagged into the gap between them, however. He stifled another belch, looking around at the plain metal panels around him, and then noticing a drain in the floor between his feet.

Baltic tossed half a dozen golden disks in his large mitt of a hand. The way they clanked together sounded almost like discarded bottle caps. When the stoutland started to feed them one at a time into the slot beside the door, Lake could see they actually were bottle caps, each emblazoned with a crown insignia. "Now, like I said: Relax. Lean back a bit too."

Lake nodded and sat back until his belly rose off the padding between his thighs and his shoulder blades settled against another pad. "This won't take long, will it...?"

"Nope. Just a couple minutes." The muscular stoutland closed the door. The latch shut and the inside of the machine started to whirr.

Almost as soon as the machine started up, Lake felt a tingle dance along his body, first along his skin, then sinking deeper. He held back the urge to fidget from that feeling, before he noticed that his low level burbles from his overfull stomach had turned to powerful gurgles once again.

Beneath the obstagoon's claws, the plump layer he had gained from the berries and candies started to firm up, more like Baltic's belly. Lake hardly had begun to explore this with his fingertips when another, unexpected sensation struck. Between his thighs, the dark type felt his testes starting to swell, crowding room.

Thoughts racing through Lake's head, he wondered if that was normal, or should be happening. He thought of Baltic and the urshifu. He thought about how this part of his training would make him no longer top heavy... This was definitely a part of it. He had no idea why, however.

As his white-furred scrotum strained and stretched to contain the swell, another sensation struck him. At first he thought it was his bladder telling him he needed to release its contents. But the swelling within his sheath and the pulsing of his testes in time with the intensity of the sensation told him it was something else. He let out a yelp as the first bout of pre spurted from his sheath, messing up his fur and drizzling down over his still growing testicles.

Lake panted, blushing deeply as he made a mess of himself, unable to stop. The obstagoon kept his claws up on top of his belly as the tingling, having reached his core, dropped down to the center of his hips. He shuddered as his scrotum swelled in another surge, nearly to his knee. He gushed at a near constant rate now, grumbling in irritation at the mess he was surely making, pre splattering off the underside of his testes in a near constant stream.

The door opened up again, revealing Baltic smiling warmly.

Before the stoutland could say anything, Lake asked, perhaps a bit louder than he'd intended. "Is this normal?" He gestured with his claws at his lower body and the only then just starting to taper off flow.

The bigger pokémon laughed, his ball-gut bouncing and testes sloshing. "Why do you think there's a drain? You're fine."

"It's gonna take some getting used to..." Lake muttered, looking away.

Baltic reached out, offering his hand for the obstagoon to grab onto.

The dark type took the offered paw in his claw, grasping.

"Now, I've got some hygienic condoms for you that you can wear to keep from soiling yourself until you can control your production a bit better." The stoutland casually remarked, using one hand to half pull half support Lake out of the machine.

As the obstagoon stood, he realized he didn't feel full at all anymore... at least above the belt. His stomach had settled, no tension in his hide from the rapid expansion and no bloated feeling. It was like this was how his belly had been when he'd arrived at the gym. Lake stood in a wide stance, not sure how to deal with the new load between his thighs as it left a trail behind him. "How do you even walk...?" He muttered.

Baltic, as always, was unencumbered by the yoga ball sized testes he sported, no matter how loudly their contents complained at the jostling. He chuckled warmly. "Training will help with that too."

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Lake had his legs propped up on one of the felled logs. In the same clearing that he'd watched Baltic and the urshifu train, he was doing inverted pushups. The obstagoon's hand claws were braced on the ground, most of his weight being supported by his arms as he used his chest to push up the mighty weight of his new belly and hanging testes.

The shiny had already half-filled the reservoir on the sanitary condom he was wearing, the sway of the stretched latex an annoying distraction when he wasn't focusing on the work. Thankfully the brand that Baltic provided him could take quite a lot, so he didn't have to change them out often.

He was also sure that if he didn't have his legs lifted away from the ground that his swollen scrotum would be resting beneath him instead of hanging, even with his arms at full extension. He continued his exercise until a familiar sloshing sound alerted him to his trainer's approach.

Baltic lightly thudded the end of the log with his fist, sending a vibration through his pupil's legs. "Time for a break. I've made curry." The stoutland watched long enough to see that the dark type had heard him, before heading back to where he'd set up the meal.

Lake finished pressing up till his elbows nearly locked, then carefully lowered one leg from the log, then the other. Ending up in a sort of downward dog pose, the obstagoon walked his claws up the side of the other log in front of him until he was upright. He pushed off the wood and started to walk towards the picnic table set up near the stewpot.

The shiny pokémon rubbed over the top portion of his chest, just beneath his clavicle. He could feel the warmth of having worked out, but he wasn't fatigued at all. He flexed his arm, digging his claws into the longer fur on his shoulder to feel at his deltoid. Though he hadn't gained much size yet, he could feel the definition coming in beneath the light layer of padding that covered most of his body.

"You know... I thought I would have been tired by now." Lake commented as he carefully draped his testes over the bench so as to not sit directly onto them.

Baltic chuckled, setting down a large plate of curry in front of the obstagoon. "That's all that energy from the candy supporting the work. But you still need to eat plenty of normal food to give your body what it needs to actually build new muscles."

The smaller male nodded, starting to scoop the heavy curry into his mouth. He alternated forkfuls of the stew and its rice, finding he had appetite to spare. Lake had cleaned the plate before he realized that he was running out of food on it. He set the plate down carefully.

The stoutland laid another plate down on top of it, just as loaded up with curry as the previous plate had been. "Eat until you're full, then you'll have enough to start showing your gains."

Lake nodded his understanding. By the time he returned to exercise, his stomach had grown taut with curry and rice, glorping and sloshing as his body worked to process it into more mass.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

The obstagoon stuffed the last poffin into his mouth, closing his eyes. The morning's training had begun with an entire platter of poffins and poképuffs, as it had for the last week. As Baltic had said, his gains were showing now. He had reached the bulk of many of his Galarian-born counterparts, but with three orbs to surpass them in every way.

Earlier in the week he'd found he had the control to only need his sanitary condoms when he was sleeping. That made him feel a bit more comfortable with his new prodigious size between his thighs.

Baltic picked up the bare platter and walked towards the stew pot with a heavy series of sloshes. "You know, it's amazing how you pack those away." The stoutland put the platter with the rest of his cooking supplies as Lake stood up from the table. "And you don't show any signs of getting a sugar rush and crash."

Lake blushed a bit. "Well... I've been self-regulating. See... I've got a kind of segmented stomach." He patted the top of his round belly. "I let a bit at a time into my properly digestive stomach over the morning."

The stoutland froze, staring.

"What is it?" The shiny raised a brow and canted his head to the side slightly.

"Do you know what you could do with that?" Baltic asked quietly. "With the right training?"

Lake shook his head. He had no idea what his trainer was talking about.

"Pokémon who have stomachs like that are pretty rare." The massive normal type explained. "Even within a single species. But, what I'm getting at..." Baltic took a deep breath. "If you trained your forestomach correctly, you could carry smaller pokémon inside it safely."

The obstagoon's half-lidded eyes rounded to full circles.

Baltic continued. "You could be a taxi on your own, no need to lug about one of those cabs like the corviknights do." He crossed his arms on top of his belly. "I always wanted to be able to pull it off, but I'm monogastric."

Lake took a step forward, his own testes letting out a quiet, tenor slosh to contrast the stoutland's bass. "Could you train me to do that?"

The stoutland exhaled slowly, and then smirked. "I don't have the equipment to start that kind of training with me today, but I'll bring it tomorrow. Come on; let's get your legs ready to carry extra weight." He extended a paw and slapped Lake on the back as he headed towards the exercise he'd prepared already.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Baltic held out a large tray of smooth, heavy stones. Each was laser-etched with a weight demarcation. "Now, these'll be safe for you to pass if you let one slip. Swallow until your forestomach is full, then we'll start today's exercises."

Lake was glad that they'd loaded up on normal food for his digestive stomach before this. He picked up a two stone weight in his claw, before easing it into his jaws. Closing his eyes, the obstagoon swallowed. He felt his throat stretch and accept the large smooth object, travelling down his throat before plopping right into his forestomach. He rubbed his chest as he focused on keeping the valve between the two chambers closed. With his free claw he picked up the next stone.

The massive stoutland watched on with approval as his pupil showed no sign of trouble swallowing the large weights. The tray emptied until almost every weight had been packed away.

A low groan signaled that the obstagoon had filled his forestomach. Lake panted softly, feeling the slight strain on his inner walls, and against the valve. Thankfully the power of all those candies and vitamins worked on his inner muscles as much as those involved in moving his limbs around.

Baltic held out a paw to help Lake up. "You've got about as much as you weighed when we met packed away in there."

Lake's eyes boggled as he took the paw. "What, really?" He looked down at his belly, seeing it sagging more than normal. In addition to the familiar mushy glorps of his full digestive stomach, there was now the muffled stone-against stone grinding and clacking in his forestomach.

"Yep. Today's exercises all will deal with momentum in your gut," The normal type guided his pupil to the logs, just adding to all of the sloshing sounds of the pair's movement. "Helping strengthen those inner muscles to keep your stomach steady. Back rigid." He ordered as they arrived.

The obstagoon was used to that kind of instruction. He tightened up his core muscles and held his legs straight, as if he was planking upright.

Baltic planted one paw on the smaller male's belly and the other on his lower back. The powerful stoutland lifted his student off the ground and rotated him to be horizontal. "Now, put your left claws on one log and your right claws on the other."

Lake did as he was told, and soon found himself straddling the gap between the two fallen trunks. His belly and scrotum hung down in a way that told him that if he tried to take this position on the ground that he wouldn't be able to bend his arms to do a push up at all.

The stoutland crossed his arms in front of Lake, nodding. "Alright, pushups. Bend until your elbows are level with your shoulders, no more. And focus on keeping your forestomach from rocking with your movements."

Taking a deep breath, Lake nodded, starting to do so. As he worked, that same feeling of muscles gaining strength he had grown accustomed to in his arms, chest, back and legs began to arise in his belly. He smiled, letting his tongue loll a bit as he got into the workout.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Lake finished disgorging weights in preparation for lunch. He had grown more confident in swallowing and regurgitating objects since this new aspect of his training had begun.

Baltic thudded his paw on the nearby table. "Alright, Curry and poffins. But! You've gotta hold every bite in your forestomach until I say you can start digesting it."

The obstagoon stood and stared, swallowing nervously. It had to be one of Baltic's full meals, plus a full sized platter of the poffins they had in the mornings. Lake carefully eased himself into his seat, feeling the now expected feeling of his scrotum brushing the ground beneath the bench with a baritone slosh. He hadn't been paying much direct attention, but through his training his testes had continued to grow, just at a far slower rate than under the influence of the Mr. Hyper machine.

Thankfully he also felt confident not having to wear sanitary condoms just to keep from messing up his sheets at night.

Baltic pushed the first plate closer to Lake meaningfully.

Nodding, the shiny began to scoop the food into his mouth. After so much training with the stones, it was actually easier for him to unload the full plate into his mouth before swallowing that than to swallow a bite at a time. Especially considering how much he was expected to pack away.

Lake set down the empty plate and lifted the next, feeling the first portion settle against the fleshy valve at the bottom of his forestomach. His fork was more used to shovel the mass of delicious stew and rice into his jaws than as it was intended. Again his throat distended with the heavy mixture, as he set down that plate and reached for another.

Baltic watched on, smiling with approval as his pupil decimated the large portions he'd been instructed to pack away. He could see the obstagoon's belly starting to swell back to the size it was when the forestomach was full of stones by the time that Lake had started going at the platter of poffins.

On a level of pure volume, the poffins looked more intimidating than they actually were. Lake had doubted he'd get all of them down, but the soft pastry collapsed easily, packing tight in on top of the swollen mass of rice beneath. He didn't feel as full as when he put all of the weights into his forestomach, in fact, until he was on his last three poffins. Swallowing firmly, the obstagoon patted his belly, leaning back a bit to keep his center of mass over his seat on the bench, and also to keep the side of the table from digging in too much on his swollen belly.

The stoutland tapped at his watch, setting a timer on it as he walked around behind his pupil, bass sloshes allowing the obstagoon to keep track of his location without looking. "You can't let any of that through before the timer goes off, understand?"

Lake nodded, starting to feel paradoxically full and hungry at the same time at the thought of not being allowed to pass any food through to where his body could claim it.

Baltic chuckled, grabbing Lake under both arms and lifting him onto his feet, his pupil's big testes knocking the bench away from the table in the process. "C'mon. We're hiking while the timer ticks down."

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Lake stood half again as tall as he did when he'd started training with Baltic. His limbs were thick and powerful, softened by subcutaneous fat but still clearly packed with muscle beneath. His neck had stretched broader, taking up most of the space between the fluffy fur that covered his shoulders. The obstagoon's belly soared out in a great ball in front of him, almost further than his claws could reach. He couldn't quite get both of his claws onto his navel without sucking it in. He was allowing his tongue to hang out the side of his mouth, instead of self-consciously keeping it behind his teeth as he'd done habitually before.

Today, he was starting on the training dummies.

Baltic had laid out a row of generic pokémon forms, as smoothly coated as the training stones they'd been using up until now. "Now, each one of these is about the size that you were when I met ya." The stoutland commented with a chuckle.

Lake's eyes widened as he drew his tongue back into his mouth. Had his sense of scale really changed that much? They looked tiny... in fact, he hadn't even questioned being able to fit all six into his forestomach.

"Now, get to swallowing. You should be able to fit all of them just fine." Baltic instructed.

The obstagoon picked the first up, looking over it, before jamming it headfirst into his gullet. He swallowed firmly, working the smooth form through his jaws. His throat stretched out with the shape of the fake pokémon as it passed. Lake felt the head press against the valve to his proper stomach and clenched it with ease, keeping the weighted figure from passing any deeper. He picked up the second.

"Now remember, you're going to be doing this with real people eventually." The taller stoutland chuckled good-naturedly. "Better t' start practicing being gentle about it now than learn bad habits."

Lake nodded and more gingerly eased the second dummy into his mouth. He focused on making sure none of his triangular teeth grazed against it as he worked the form in. Thankfully, it didn't seem to take too much longer than the first dummy to get down.

"That's good form." Baltic complimented as he pulled out a small device. "Now each of those dummies is fitted with an oxygen meter."

The obstagoon swallowed firmly, picking up the next dummy in his claw. "Why..? Dummies can't breathe, so it's not like CO2 will build up in there." He carefully worked the next one training form past his jaws.

With a smirk, the muscular stoutland prodded his pupil's swelling belly. "Methane poisoning. You gotta be careful to keep too many of those byproducts of digestion filling up your forestomach." Baltic backed off with a slosh as he tapped on his device a bit, getting a reading from all six dummies on the screen at once. "You either have to train yourself to not belch, or be really good about swallowing fresh air to displace it all."

"I'll eventually have to be swallowing air anyway to replace the spent oxygen for passengers, right?" Lake asked as he finished the second-to-last dummy.

"Yes, but it's probably more pleasant if they don't have to smell your curry belches as well." Baltic laughed. "Come on, finish swallowing that so you can get to doin' squats."

Lake nodded. Baltic's method of doing squats required balancing on two posts buried in the ground, high enough that even the stoutland's prodigious testes didn't touch the ground when he reached the lowest point of the exercise. Balancing like that helped with core strength and posture as well as powering up his glutes. The obstagoon swallowed the last dummy and stood, making his way to the half-buried cabers with a rich baritone slosh to his step.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Lake vaulted a fallen log. He breathed heavily, but slowly, making sure to not descend into shallow panting. When his claw struck earth he continued running, following Baltic through the woods in the wild area.

The stoutland had his eye on the oxygen meter in his hand. "Getting a lot better at regulating, Lake. That's good." He changed directions, starting up the hillside with no path in sight.

With an upset slosh, the obstagoon pivoted to follow. By this point, he was nearing his trainer's size in every way. This of course meant that his testes brushed against the undergrowth of the forest even when he was at full speed. As Baltic had promised, the training had helped him stay mobile with such a burden between his legs, but that didn't mean it couldn't still be annoying.

Inside his stomach, he felt the six dummies piled in alongside all of the training weights. He was far more aware of their positioning than when he'd started, and could tell when they shifted about within his forestomach. The mass was present, but distant; he didn't feel as though it affected his movement anymore. At least, not as much as his own kettlebells swinging between his calves.

Baltic chuckled at the loud sloshing coming from his pupil as he ran, mirroring his own potency more than ever. The stoutland looked back over his shoulder, taking deep breaths as well. "You know, it's kinda funny how much of your new mass went to your loins when you're-"

"Asexual? Yeah. Been getting that a lot." Lake replied, pounding his hind claws into the soft earth to keep up with the experienced stoutland. "Anyway, not like libido has anything to do with being ace." He grumbled a bit. He'd been having to deal with the normal questions about his sexuality far more often since his body became an enormous mass of traditional masculinity.

Baltic led them over the crest of the hill, starting the different challenge of keeping speed consistent when gravity wanted their massive bodies to rocket all the way down. "So... do you...?" The older pokémon's testes practically roiled with the new jostling motion of going downhill.

The obstagoon groaned, rolling his eyes. He'd thought that the stoutland wouldn't be one of the myriad of people to bug him about this, but apparently he'd been saving the prying questions. "No, I don't have a libido, but that's beside the point I was making."

Baltic came to a halt as they re-entered the clearing they'd been training in this whole time, checking the oxygen meter. "Well, you're able to keep consistent while annoyed with an old pervert, that's good." His loins continued to audibly slosh for a few moments after he came to a complete stop as their contents gradually settled.

Lake boggled, panting a bit as he shifted his weight from foot to foot, ignoring the fluid sounds his own body produced. "What, you just decided to bug me to test how I reacted?"

The stoutland smirked. "Alright, let out the dummies, but leave the weights. Working out with the bladder again today."

The shiny stuck his blue tongue out after his trainer turned away. It was hard for Lake to tell whether that whole line of questioning was on purpose or not. He sloshily walked over to the large tray that Baltic stored the dummies on and carefully began to bring them one at a time up his throat. As he passed them from esophagus to his claws in sequence, he saw out of the corner of his eye the boulders that he had seen the stoutland and urshifu train with months earlier.

He nearly bit down on the dummy halfway through his mouth at the sight of them. He managed to lock his jaw before that could happen, and pulled the form free fully. Could he really use those as weights himself? Lake pondered this as he finished freeing the weighted forms from his forestomach.

Baltic sloshed over holding what looked like a deflated yoga ball attached to a hose. He held it up in front of Lake's face.

The obstagoon obediently opened his jaws and started to swallow it. He worked it down into the forestomach with the mound of weights. They were approximately the volume of one of the dummies and twice the mass all together.

Once the bladder had been fully sequestered, Baltic began to inflate it with a small motor.

Lake held his claws on his belly as the air pressed the elastic sack against the insides of his forestomach. His gut slowly distended larger and larger as the training stretch was applied. By now the obstagoon's forestomach outsized his digestive stomach by at least quintuple times over, but Baltic kept stretching it.

When the stoutland determined that the inflation was sufficient, he stopped the pump and closed a valve in the hose. Setting the pump aside, he walked toward the boulders with his characteristic sloshing emanating from between his calves. "Now, Pec flies. Get on your back on the log, reach out and grab one of the weights in each claw, and bring them together over your chest."

Lake swallowed with part of the hose still sticking out the corner of his muzzle, surrogating his blue tongue. He carefully got himself up on top of the felled log as instructed and laid onto his back with a heavy slosh from inside his true stomach, belly jutting into the air above him. The obstagoon closed his eyes, reached out and grasped onto the rough rock. He took a deep breath, and then exhaled through his nostrils as he lifted.

Baltic nodded firmly as the boulders rose to touch one another, again and again.

Lake stood with his hands on his hips at the edge of Motostoke, letting his tongue hang out the side of his muzzle. He was waiting for Baltic to come out of the taxi office nearby. Today was the day he was being registered as a taxi. Or more specifically, his forestomach as a cab. His broad chest swelled with each deep breath he took, pectorals crowded together atop the curve of his enormous belly. He had gained a bit more padding over his body in the course of his training, covering up most of his definition. His pecs, however, showed through easily, advertising his strength as much as his size.

He no longer seemed to mind that much that his testes grazed against the short-cut grass he was standing in with his every movement. The orbs within his scrotum mirrored the shape of his belly, adding to his overall round look. He smiled a bit. To be strong and round... that had been his goal to start with, and he had achieved it.

Regular sized pokémon occasionally rubber-necked him, staring at his enormous body. Lake realized that a few short months ago he stood about their heights. Now they were eye level with his deep navel.

A pair of eeveelutions, an umbreon and a sylveon, looked between Lake and the taxi office at a distance. They were leaning together, arm in arm, and the sylveon's ribbons were clearly curled around the dark type.

Lake gave a friendly wave when he noticed them.

The pair approached, staring in awe up at him. Unlike most they didn't stop to stare at his testes, which was a welcome change, Lake thought. The sylveon spoke up first. "Are... Are you a taxi?"

The obstagoon chuckled, patting his gut as it let out an empty groan. "Why, do you need a ride?"
