Unlike the less competitive and especially less dangerous regular Pokemon Nom leagues, the Underground equivalent had always kept itself well-hidden under the shadow of the large accepted gathering of Pokemon interested in devouring each other. The crucial difference being that instead of the safety of the participants being paramount, the thrill of the Underground league is in the veritable lack of any safeguards against being digested... or against going overboard when climbing up the ladder during matches.
”... you're back here already, like that?”, a vaporeon named Wrill exclaims while pointing at Tsiik the umbreon's rather hefty looking belly, the loud churning of Tsiik's gut mixing into the discussion. ”Yeah! Got to be faster to catch all the prizes, you know – thought one day was enough to soften them up to fit in more.”, the umbreon pipes up cheerfully while rubbing the side of her distended midsection and eyeing Wrill's rounded yet much smaller belly. ”Aren't you cheeky... I'd rather be a bit slower and not split my belly open, but since you're here, lets fight!”, Wrill replies in an amused manner, eliciting a sly grin from Tsiik as they both stroll over to the nearest battle ring with their bellies swaying.


Some time later Tsiik finds herself eyeing for prospective opponents again, after having gobbled up the dismissive vaporeon – something which she did rather enthusiastically. Although the aftermath turned out to be somewhat embarrassing as she had to be helped out of the ring due to her stomach having swelled enough to make moving almost impossible. But given the nature of the Underground league, this was not an unusual occurence, as everyone was encouraged to go dangerously overboard for the thrill and declining challenges was not allowed.
”This didn't turn out too bad yet~”, Tsiik ponders while happily enjoying the languid struggles of Wrill within her bloated stomach – most of her body comfortably laying on top of her midsection with only her hindpaws touching the floor. The tightness of her stomach lining hardly bothers her yet and the vaporeon's squirms feel more akin to massage, hence she's not overly concerned when a driven looking mightyena pushes through the crowds to stop before her.

”You're at the top of the charts today, greedy umbreon, as your stomach shows – I will fight you!”, the mightyena barks almost immediately after he stops before Tsiik, pointing at himself markedly. She responds with an agreeable nod and a chuckle. ”Greedy, eh? Well I still have room for you...”, she counters his challenge, and with the deal sealed, both make their way to the battle ring.

Once the battle is over, Tsiik finds herself to be the victor... though she's seriously regretting her earlier decision to return to the fight so soon, when she's gingerly carted away with the mightyena now stretching out her belly as well. As per the rules of the Underground league, she's moved into one of the side rooms to engage in ”digest or die” without help as the vaporeon and mightyena relentlessly assault the walls of her enormously distended stomach. Although she's well aware that she's watched and likely recorded through the shiny black upper row of windows which encircles the top of the room – seeing how one major draw of the more expensive seats for the audience is to get to see the results of contestants misjudging their capacity or other abilities.Nauseous and enduring a massive belly ache, Tsiik clutches her muzzle as she lays helplessly atop her grossly swollen midsection, her body constantly rocking due to the vicous jolts and shoves directed at her stomach from inside. ”G'dammit, this would've been my record so far...!”, she groans as she throws sideways glances at her considerable girth, seeing how her teats stand perkily on her straining hide. ”Shit, don't think I'm gonna make it – uuuurgh – gotta enjoy being full before those two pop me!”, she gasps when another barrage of hindleg kicks sends a flash of pain through her belly, the wildly thrashing shapes of the vaporeon and mightyena constantly making impressions on the umbreon's dark hide as the agony mounts…

”Looks like we're still in the league, unlike whoever was here before us.”, the mightyena comments nonchalantly as he shakes away the worst of the thick goop which has stuck to his lush furcoat within Tsiik's stomach. Tsiik herself makes no comment as she lies motionlessly on the floor, her tongue lolling and lifeless eyes fixated to a spot on the wall... despite her crying and bargaining a little while earlier, the nearly two-hour-long combined effort of the mightyena and Wrill had finally burst her overloaded stomach with a mighty splorch when the two had repeatedly slammed their bodies into the same spot. Covered in the remains of her earlier prey and stinking umbreon intestines, the vaporeon watches the mess slowly seep down along her smooth skin before turning to the mightyena. ”I warned her, but – it's good she didn't take heed of that. Not the first time I've burst out like this.”, she muses and makes a shrugging motion, glacing at her own belly. ”But now that she's done for, I want more – so I challenge you right away!”, she adds with a grin, receiving another grin in return from the mightyena. ”Yes! Lets fight – I will not lose, either I eat you or you will pop!”, she laughs and gives one more look to the ruptured midsection of Tsiik before the two wander off to shower and fight – the dead umbreon's remains left behind for the cleaning crew.
Much later…

Although neither Wrill or liepard were exactly cornered in the wide quiet hallway where the Houndoom, and the Umbreon working as her sidekick, had caught up with the duo during late evening after the Underground League had shut down for the day – neither of the latter are concerned with them fleeing given how ponderously both the vaporeon and the liepard had been walking along with their heavily swollen and noisy bellies. Not to mention now that they had both sat down on their haunches, even getting up with their stuffed midsections would take much effort. Hence the Umbreon rather liberally prods and touches the frustrated Liepard's belly to further annoy her, while the Houndoom speaks and Wrill keeps looking at everyone nervously.

”I thought we had a deal that you two wouldn't take on any… side deals, as long as I'm paying you. There have been some questions due to poorly covered disrepancies…”, the Houndoom starts with a bothered expression, her gaze rolling first past the Liepard who repeatedly tries to shoo the Umbreon, and then past the vaporeon who fidgets restless with her fins rippling. ”I – I don't know anything about that! I swear I only did the jobs you asked for… I bet she has something extra in her stomach!”, Wrill blurts out and motions towards the Liepard, earning a hiss from her while their greatly distended bellies slosh and wobble from their motions.
”Ridiculous – would I risk my portion for small pebbles gained from personal vendettas? You're barking up the wrong feline...”, she retorts with a tailflick, earning a scoff from the Houndoom who quickly nods at the Umbreon, prompting the Umbreon to produce a small device from behind her which she straps to the forepaw she used to agitate the liepard. ”Then it's good that I prepared something to settle this dispute, seeing how one of those whose disappearance has caused inquiries did have a tracker on them. Which does survive stomach acids.”, the Houndoom says calmly as the Umbreon begins to run her splayed forepaw over the curve of the Liepard's distended midsection.

Nary a few seconds later the device emits a series of shrill beeps in varying intensities, the liepard gulping audibly when the tone rises from how the Umbreon sinks her forepaw into her belly – the liepard's tail lashing furiously when the Umbreon unceremoniously steps over to the vaporeon to begin repeatinging the process on her heavy belly while the Houndoom springs up to leap behind the liepard. ”Mew, umm, this is a misunderstanding… there must have been more trackers…!”, she exclaims hastily and writhes when the Houndoom silently restrains her, ears swivelling down. In the meantime Wrill breathes a small sigh of relief as the device doesn't react to her swollen belly, warily keeping her dark eyes on the Liepard and Houndoom. ”Well, only one way to find out, right? You are well aware of how we figure out the proof.”, the Houndoom growls at the Liepard over her shoulder while tightening her grasp thanks to her desperate squirming… whereas the Umbreon casually puts the device away and produces a wicked looking blade to drop it in front of the vaporeon. ”You're in the clear so far – dig that tracker out and we're done here.”, the Umbreon tells her to coax her to carefully pick up the blade, Wrill's heavily laden belly dragging the floor as she approaches the increasingly terrified liepard.


”It was a lapse of judgement! You don't have to do this…! I'll work for free for the next year!”, the Liepard cries and struggles against the much stronger Houndoom who keeps her jerking at a minimum when Wrill traces the blade over her taut underbelly to figure out the best way to proceed. ”Nothing personal, you know...”, the vaporeon winces when she awkwardly leans closer with her own belly flaring against the floor, and abruptly sinks the sharp blade into the middle line of the Liepard's bloated belly just below the chest. Moments later the Liepard's shrieking echoes in the empty hallway when Wrill hesitantly starts cutting wile trying to be serious about it due to how she feels the Umbreon's gaze on the back of her head. The sudden putrid blast of gases and the squirting of digestive juices makes the vaporeon gag when she sinks the knife deep enough to split the Liepard's large translucent stomach open along the way as she cuts downwards, the other two merely scrunching her muzzles. But gases and liquid are not the only thing to escape the confines of the hapless feline Pokémon's stomach… when the cut widens, a haphazard collection of partially digested collars, bones and cartilage bound by sticky masses of digested flesh, spill out all over the floor, the Liepard's shrieking turning into gasping and guttural grunting gradually as shock hits her.


A little later on the Umbreon has left to avoid arousing any suspicion, leaving the Houndoom and Wrill alone with the liepard's carcass – the vaporeon having diligently filled her belly further with the spilled stomach contents during the search for the tracker. Although as her stomach stretches close to comfortable limits and the acrid taste of one-digested scraps bothers her, she groans while her forepaws rise to cover her muzzle. ”… could we just dump the rest? Tastes like barf and I don't want to -”, she begins to say before being swiftly cut off by the Houndoom rising to loom over her, one claw tapping Wrill's grossly distended and taut belly markedly. ”I think you forget who is the boss here, whelp. Even if you're much less dumb than you look, I know there's damning evidence gurgling away in here as well, you just didn't fall for my trap like the other dumbass here. So shut up and keep eating so that I don't have to do any more cover-up, and we're even.”, the Houndoom replies harshly as the vaporeon's head fins wilt. ”Though you did me a favour because there's one less potential blabbermaw, and once you take her share of the deal as well, you won't have the capacity for any extra.  Do you think so?”, the Houndoom continues, extracting a nervous enthusiastic nod from Wrill who lowers her forepaws at the same time as she Houndoom turns back to the collection of wet stomach contents – resuming feeding them to the vaporeon who obediently swallows them down while rubbing her upper belly, secretly hoping to gain a more stretch to her stomach to be able to deal with what seemingly awaits her in the future.



Being the sole enforcer of the shady deals the Houndoom and Umbreon relentlessly cook up, is ultimately not bad at all, Wrill ponders as she watches a match go down in one of the several battle rings – her now completely empty slim belly making occasional growling noises which intensify severely when the victor in the ring gobbles up the loser and leaves proudly with her sagging midsection which keeps distorting from the struggles of her former opponent. It had taken an entire long week to fully digest the remains of the Liepard and everything which had leaked out of her stomach, but now she's empty again and thus ready to tackle her contract with the Houndoom. Which is the other reason she was following the match, she knows that in the crowd rush to switch rings after a ring is cleaned out from the detritus of multiple battles in a row, she can shadow her target in impunity – this time it's a rather rushed looking flareon who swings into a side corridor towards the lower-tier competitor quarters.
Which is perfect for the ravenous vaporeon because there's hardly any traffic there for the moment and thus it makes for a great ambush site… which is what she demonstrates mere moments later when she dashes after the flareon to boldly sweep her rear quarters into her huge maw on the move.

The flareon hardly has time to react apart from trying to dig her claws into the hard concrete floor of the facility – a pointless gesture given how rapidly she's being dragged into Wrills's maw and pulled deeper by the muscular stretchy gullet which bulges around her hindquarters. ”Wa-wait! I don't deserve this, I did all he as-”, she exclaims before the squeeze forces the air out of her lungs and she helplessly disappears between the vaporeon's jaws with a wheezing groan, gritting her teeth until the jaws close after her head and forepaws. Moments later Wrill makes as speedy exit from the scene as she's able, her distended and sagging gut distorting all over as the flareon adds to her muffled protests with a fair amount of struggling.
However full-bellied participants are hardly a notable sight in the shady facility so the vaporeon is not exactly hassled when she makes her way around to find her target to stalk… something which her girth makes harder already because the luxray she's after, is not at all clueless to the name of the game. Thus even though she attempts a sneaky approach, the luxray immediately spots her and begins to edge away from her in the sparse crowds while throwing surreptitious glances at her. Seething as she knows that she cannot chase the luxray too openly, Wrill creeps closer to force her quarry  to slink up a rarely used set of circular stairs when the main route becomes congested thanks to a bottleneck. The Vapreon, however, doesn't follow because of her obstructively hefty belly and instead gives the luxray one last glance before merging with others below to vanish into the complex. Meanwhile the luxray decides to continue her journey along the catwalks, hoping to frustrate her pursuer by deliberately going around in circles and wasting time.
Two hours or so later the luxray wriggles through a rarely used maintenance passage which has a convenient opening close to the facility exit, hoping to making a quick escape after leaping out – but catching a glimpse of the exit through the hatch which she paws open, causes her frazzled nerves to be soothed too much and thus she jumps out without looking too much.


Which just happens to land the luxray straight into the waiting greedy maw of the vaporeon who had settled on her haunches under the hatch opening a bit earlier, her bluish form partially melding into the shadows as she gobbles down the powerfully writhing and cursing luxray… or at least it very much sounds like shrill cursing even if the words are unintellegible. With gravity assisting in the swallowing the luxray rapidly slides through the Wrill's roomy gullet while causing plenty of shifting bulging and swells out the predatory pokémon's midsection further, to the point where the vaporeon is barely able to drag her prey-laden gut away as she drops down on all fours with a shiny luxray tail still swishing between her teeth.


”You're tackling your new extra contracts rather passionately – how long until you're ready for more?”, the Houndoom ask as the duo meet in a section which has been closed for long-term renovations and repairs… the comfy damp watery smell making the awkwardly full vaporeon even more thrilled as she waddles beside the Houndoon. ”Give me a week or so… I'd really want to go at it sooner to avoid losing this feeling, but I can't really take them down like this!”, Wrill replies with a chuckle, her fully extended head- and neck-fins rippling slightly while her wide floor-dragging gut churns and gurgles loudly, its form rather smooth and round compared to how it was few hours ago – the change giving a clear indication of the now rather mushy state of the flareon and luxray in the huge stretchy stomach which currently occupies most of her body.
”Excellent. I will send you the contracts out early then to let you decide for yourself, the more you process the faster money will roll in. Although you're such a greedy bastard that I don't think you're doing this for money.”, the Houndoom replies with a sage nod and bumps her hindleg into the vaporeon's round flank, prompting an impish grin from the latter when they part ways without another word – Wrill taking an unnecessarily circuitous route to her hiding place simply to relish the heaviness and sloshing of her achingly full stomach before she slips into her water pool to curl up around it.

Some weeks later Wrill wistfully thinks of her enormous past meals as she writhes in the uncomfortable harness which suspends her above the floor – her tail flapping restlessly against the bare concrete while her legs flail. She was still completely in the dark about the actual details because the Underground league security officers who had apprehended her by surprise few days ago as she had been digesting her latest catch, had not exactly told her anything despite her complaints and pleading…. and  they hadn't split her swollen belly open at the spot either, but instead she had been dragged away and subjected to multiple agonizing stomach pumpings and an intestinal flush, after which she had been roughly shoved into a cell. For the two days after that she had not seen her accomplishes or anyone else for that matter despite banging at the bars to demand someone to explain the situation to her – but it had eventually become crystal clear when she had been picked up from the cell to be taken away into a well-know but sparingly seen part of the complex where punishments for transgressions are handled.  Amid her squirming, groveling, and distraught whining as she had been fitted into the harness and hoisted up, she had learned that she would meet both the Umbreon and the Houndoom really soon… then she would be forced to eat them… and once they had digested for a while to soften, her own greedy stomach would be pumped full of cement to make an example out of her.


The mere thought of such a fate makes her stomach twist itself into knots, but she doesn't have much time to contemplate her fate before the Jolteon who has been appointed to carry out the combined punishment and execution, arrives with the bound Umbreon in tow – quite literally as the groaning Umbreon is being dragged on her back over the floor.
”I have rights! You can't prove anything! I'm not going to go into that maw….!”, the Umbreon screeches in vain as the Jolteon steadily hauls her all the way over to the dangling vaporeon whose ravenous hunger and loudly growling stomach area already taking the best of her, and thus she's already drooling heavily enough to form a small pool on the floor by the time the Umbreon's hind quarters are presented to her by the weary looking Jolteon.
”I've been listening to you jokers long enough, and I don't care what we can prove or what you want – I'm here because I was told to get rid of you.”, the Jolteon hisses as she gives the Umbreon a massive electric shock to shut her up, awkwardly hoisting the stunned pokemon up enough to cram her tail and legs into the restlessly swinging vaporeon's waiting jaws, giving the Umbreon a hard enough shove to force her all the way to Wrill's gullet. From there eager swallowing begins to rapidly pull the Umbreon deeper, the sensation of being partially surrounded by slimy powerful muscles causes the pokemon to snap back to life.

”Oh no no no no! Let me out this instant, you greedy – gyaaah!”, she yells while her hindquarters are squeezed and compressed hard by the muscles which yank her abruptly mere moments later, the motion stunning her as she ends up with only her forepaws dangling out of the vaporeon's maw. The Jolteon merely watches, balancing on her rump with his forelegs crossed and a huffy expression lingering on her face as she observes the blinking Umbreon being inundated with drool when she slides deeper, ultimately disappearing behind Wrill's teeth. The large Umbreon-shaped bulge travels swiftly down the vaporeon's neck into her stomach which swells equally rapidly, the resulting squirmy bulge causing the reluctant predator to giggle uncontrollably despite the circumstances.

However already before the vaporeon has fully gobbled up the first condemned prey, the Jolteon leaves for something – and eventually comes back with a writhing and growling bound Houndoom which she casually drags along by the tail. With her muzzle tightly muzzled with a leather strap, the Houndoom is unable to say anything but her vicious glares tell even more. ”Mmmph! MMPHH!”, she grunts as she Jolteon pulls her all the way and briefly drops her off in front of Wrill. ”Normally we'd give an opportunity to say last words, but since you're a biter, you'll have to do without~”, the Jolteon comments with a shrugging motion and jabs the vaporeon's distended belly here and there while the suspended predator's legs flail in frustration. ”Plenty of room in there… so lets do this! Don't want to spend all day doing this.


Without further ado the Jolteon hoists up the Houndoom's hindlegs and feeds the straight into Wrill's waiting maw, the neckfin of the vaporeon fluttering in distress as her relentless hunger overtakes her more sensible instincts and thus she eagerly snaps up the offered legs… slurping them up with help from the Jolteon who keeps feeding the now wildly thrashing Houndoom into the ravenous maw. This time it does take more effort on the behalf of the vaporeon to swallow the larger pokemon and the room fills with the lewd moist noises of the struggle of devourment as the fuming Houndoom goes down the hatch bit by bit. In fact the Jolteon shoves hard at the Houndoom a few times despite her muffled protests, due to how it seems that Wrill is about to choke from how hard her bulging throat spasms – but once most of the Houndoom has ended up past the teeth the situation normalizes mostly. The pool of saliva on the floor keeps expanding when Wrill tackles the curvy horns of the Houndoom, the latter still shooting daggers from her eyes at the Jolteon all the way until her head slips into the watery depths of the vaporeon's maw to start adding to considerable girth.

With both of her former buddies in crime now writhing in her obscenely gorged belly while beating it from the inside ceaselessly, Wrill groans and settles to hang from the harness in defeat, her fins wilting further from the sight of what the industrous Jolteon is hauling in. First a wheeled contraption which is clearly some form of a mixing device and a pump, and after that a carriage filled with cement sacks.


”C-can I just digest them and be done with it…? Pleaaase?”, she grovels while the Jolteon setups everything and breaks the first sack to start feeding it into the machine, turning the shrill electric whine into steady chugging when the water and cement enter the confines of the machine. ”I don't want a bellyful of cement, really!!”, the vaporeon cries when the Jolteon moves on to fit the hose-connected muzzle on her, but her objections are rather soundly rejected when the Jolteon forces the muzzle on her and affixes it in place.

”Should have thought about that earlier, you dumb greedy thing, I only work here anyway… and I've been ordered to make a long-lasting example out of you.”, the Jolteon replies swiftly when wet cement begins to flow through the hose and straight into helpless Wrill's gullet – her stomach soon gradually smoothing out from the heavy fare while the lively shapes of the Umbreon and Houndoom become increasingly vague. In the meantime the Jolteon keeps dumping more cement into the intake on top of the machine, paying no heed to the pleading eyes of the vaporeon who keeps bloating at a steady pace with the suspension harness creaking from the increasing load. By  this time there's no visible trace of her prey either as the cement has already completely rounded out her gut, entombing all the contents.

The final process of loading up the greedy vaporeon takes hours, but the Jolteon leaves nothing for chance – amid re-filling the cement mixer she also makes sure that the cement flows smoothly and that it disperses evenly within the Vaporeon's enormously swollen stomach, jostling and shoving at her belly to make sure of it when-ever strange clumps appear.
Once every single cement sack has been used and Wrill has been cleaned of all the spilled cement and other detritus,  she's hauled over to the main entrance of the league complex to let her grotesquely massive and excruciatingly slowly hardening stomach function as a warning to everyone who passes through – even if she seems to be outright enjoying her heavy predicament half the time...
