The mute nature of an empty stadium locker room was soon interrupted by a famous female kangaroo walking in and sitting on a bench. She flipped her short hair to the side as her tall ears twitched a little in fear of the events that would go down only hours from now. This was Olivia, a rather famous MMA fighter that had gone undefeated for years in her hometown. She had dark amber fur and a very well-toned and lean figure, with the exception of her prominent rear-end, which was hugged by her black gym shorts. But a bit of extra padding could help absorb a few blows in a fight, right? The only problem was that she was starting to grow tired of fighting, which was wearing her down to the point where her back was already starting to have a few problems. Olivia had plans on retiring for weeks before then, but she decided that she would wait it out until after fighting the challenger that had been moving right up the metaphorical ladder with a winning streak that rivaled her own. The main problem was that the match was tonight, and the weakness was really beginning to hit her hard.
 
Even then, she didn't want to call the match off, because that would make her seem like she was chickening out of the fight with the only person that could really have a chance at stopping her. On the other hand, if she did participate and lose, then all of her fans would be deeply disappointed by the fact that she ended her career with a large loss. The rival in question was a bulky snow leopard named Cassandra, or Cassie, that the roo had already grown to know pretty well. She was laid-back and rather rude, and could pack quite a punch and was a bit of a braggart about her fighting success. The two weren't exactly friends, but neither of the two hated the other either. Most of their exchanges simply consisted of some joking and taunting about the fight between the two of them, which only put even more pressure on Olivia.
 
The roo popped open the cap of her water bottle, and chugged some of it down before letting out a sigh. She was really not in the mood to fight tonight, and would consider going at any lengths to stop this fight from happening in the first place. After all, the best way to avoid making anyone look at her in a lesser light would be to both stop the impending bout, and still show up to the ring to see the crowd... "This damn fight... Why couldn't it have been a week ago or somethin'? I'm not gonna stand a CHANCE against 'er..." Olivia said in herself in her Australian accent, pondering still as she moved to a lying position on the bench. At that moment, Cassandra slammed the door open and stretched her arms out. The leopard was wearing grey skin-tight boxing shorts with a less tight top to match it. She almost immediately noticed Olivia when she walked in, and decided to throw in a bit more taunting for good measure.
 
"Phew! Just got back from the gym. Don't go there too often, since it's way too much effort, but I thought I could use a little bit of insurance. But I bet my body was still perfect enough to cream ya out there even if I didn't go~" the leopard laughed, flexing her arm a little to solidify her statement. While Olivia fought more with her speed and strategy, Cassie was more fond of using her brute strength to take out anyone in her path. The two were still mostly the same size though, maybe with Cassie having about a half a foot over Olivia. It probably would've been a fair fight if Olivia wasn't so sore and pessimistic at the moment. But as it stands, she wouldn't likely have the strength to knock her bulkier opponent to the ground, and she can only dodge hits for so long before getting tired of it. The kangaroo turned her attention toward her and rolled her eyes, ready to fire back with the taunting. "Yeah, I could tell you went just by looking at you. I gotta admit, I saw some of that muscle turning to flab last week." she smirked.
 
"I'm sure that flab would've crushed your fat ass anyway, Fatass~!" Cassie replied, using her nickname she came up with for her. With one look at how kind genetics were to the kangaroo, it's clear to see how she would've decided on the name. Olivia sat up, and the competing leopard was quick to sit next to her on the bench. "I guess we'll see who's really getting creamed tonight, eh?" Olivia continued, getting up and away from her to go check on her locker before Cassie could threaten her any more. But Cassie did anyway, quickly going after her to lift her up off of the ground and stare into her eyes with a cruel smirk. "Yep. And when it's over, they'll have to call in the paramedics to scrape ya off of the ring..." Olivia shuddered a bit from her intimidating tone, before being dropped back onto the ground. "Well, I gotta go get a drink. I'll be back in a few minutes to rough you up a little before the fight~" The snow leopard joked, exiting further into the locker room and disappearing past a wall of lockers. From all of this intimidation, Olivia was scared enough to come up with a plan much faster. And when she finally decided on it, the roo felt nervous about it, but knew that it was the only real chance she had. Besides, it could end up being fun...
 
All she needed was a bit of surprise, and the lockers gave her exactly what she needed for that. Olivia went right up to the wall of them, standing right next to the walkway Cassie walked out from. She wasn't very proud of this idea, due to the cheap and unfair nature of it, coupled with the fact that it would put a quick stop to the leopard's career, but she'd also been waiting on an opportunity to try something like this for a while. Of course, she was planning on attempting take the whole leopard up her ass that she made fun of, and churn her up in her stomach. Either way things went, someone was going to get creamed tonight. Anticipating her return pretty soon, the kangaroo quickly pushed down her shorts to reveal her full uncovered ass to the empty room, and set them aside to put back on later. Then, Cassie's footsteps began to echo throughout the room once more as she got closer to her spot...
 
"Ah, that was refreshing~ Now I'm all fueled up and ready to pummel you into th-OOOF!" The second the big snow leopard turned the corner, Olivia kicked her leg out to trip her. Her ankle was very strong, which left the roo hurting in the foot somewhat. But the surprise attack was still just enough to make the leopard fall right onto the tiled ground, face first. Rubbing her head now, Cassie turns over to look at the kangaroo that did this to her. "What the hell was that about?! I'm going to kill y-MMMPH!" Her threats were interrupted a second time, but now it was because she had a face-full of Olivia ass. The roo herself was now sitting triumphantly on top of her head, adopting more of her teasing attitude as she grinds herself against her face slightly. "Hah~! I think we should make this match end before it starts... what'cha think?" Olivia teased, as the bulky rival struggled at lifting her off of her head, being smothered by her rump. "Get... mmmph... uck... off me...!" She tried to protest, not being in the best position to speak. "I'll take that as a yes~"
 
From there, Olivia used her waning strength to push herself harder against the buff leopard she was meant to fight that night, Cassie's face being shoved further between her ass until her nose met her tailhole. The kangaroo was panting at this point, and had to wrap her entire thick tail around the other's body to make the next step easier for herself, which constricted her arms to her sides. "Let's see how much that extra muscle will 'elp once you're in a stomach~" Olivia teased one more time before focusing all of her weight onto the struggling fighter's face. This caused her face to push right up into her puckering tailhole, spreading it wider and wider to accommodate her size as she cussed and struggled. Both were muffled and slowed by the tight, warm, musky environment that was the roo's ass.
 
Now that the hardest part was out of the way, Olivia began to shove using her hands, and pushing with her tail to get her future meal deeper inside of her asshole and into her bowels. Her hole spread wider to work it's way around her shoulders, then shlurked over her shirt, shorts, and finally her feet and tail as the roo sweats profusely from all the effort that it took. Her tail uncurled itself from her as it passed over her chest, moving toward Cassie's shorts to shove up against her crotch before tearing through the bottom of her shorts and pushing up against her pussy to get her even deeper. She wound up being so furious and conflicted about the sudden roo tail being shoved up inside of herself, Cassie began to fight even harder. It didn't last long though, as her tail soon removed itself and her pucker finally closed itself again after her feet slipped inside. Rubbing the excessive moving bulge that was slowly making its way up her bottom half now, Olivia leaned up against the wall behind her and rubbed her aching back with the other hand. "Ooooh... You're pretty filling in there... Didn't even know I still had it in me. Maybe I could've won anyway~" She snickered, feeling her inner walls squeeze and compress the fighting leopard higher and higher through her intestines until Cassie finally began to push through the bottom of her stomach.
 
Here, she was finally able to catch a breath and speak again as her muscular body slowly made its way into the roo's tight and relatively small stomach. Olivia clearly wasn't meant to take in meals the size of herself, but she found herself taking them anyway occasionally. "You absolute piece of shit! You can't hold me in here forever, Fatass! When I get out of here, I'm going to tear you apart!" Cassie ranted, pounding against the slippery and wet walls of her stomach, which could be seen by the sudden bulges shooting out from her gut. It was difficult to keep her down in there through the fighting, but it also made the roo a bit gassy, releasing a loud belch that lead to the inside of her gut becoming even more tight around her. By now, she was completely inside of the organ, and couldn't really move at all after the sudden release of the precious air inside of her fleshy prison. It didn't help that she used up most of her energy trying to push out, now panting in the sweltering heat and tight confinement of Olivia's groaning stomach. "Huff... huff... I swear, I'm going to crush you into dust... I'll, I'll..." At that point, it had gotten to be a bit too much for her to handle. She was unable to finish her threat before passing out from all the previously mentioned factors. Now, she was simply at the mercy of Olivia's churning stomach. "I'd like to see ya try~ Gonna be hard once I melt 'cha up into fat."
 
Now that she had the leopard she was meant to fight right where she wanted her, Olivia made her way over to her bag to grab her phone from her bag. Knowing that the hefty amount bulging out of her gut (and making her figure appear to be much less slim than usual) would probably cause her to fall asleep for quite a while, she set an alarm for a few hours so that she could wake up in time to arrive at the ring and deliver the news to her audience. Of course, she couldn't exactly admit that she ate her competitor in the locker rooms, so she would end up having to come up with a lie to excuse both her unprecedented weight gain and unannounced disappearance of her rival when the time was right. But until then, Olivia napped on the bench and used her bag as a pillow while Cassie was taken care of inside of her loud and powerful gut.
 
Over that time, her bulging amber gut released a few *GRRGLRGLRGLL*...s and *BLORRRRRP*...s as it filled with her digestive fluids and ate away at Cassie's white and black fur, clothes, and everything else. Everything that made up the muscular fighter was promptly digested over the next few hours and a bit of her was absorbed into her stomach and already pudgy butt. Clearly, it would take more than a couple trips to the gym to manage all the extra fat she would put onto her by the end of it. The only thing she couldn't manage to break down was the skull, which was characterized by its four large and sharp fangs on the top and bottom. It was softened up a bit from the digestive process, but couldn't quite break down like the other bones. Before anything else could happen, the alarm on the kangaroo's phone sounded and she jumped awake. "Oi! I gotta get ready to go on the ring in 10 minutes!" She exclaimed, reaching over to grab her black shorts as she prepared to break the news to everyone. The black shorts hugged her tighter than ever before, and were very hard to wear due to her new size.
 
Meanwhile, on the stage not too far away from the predatory kangaroo, stood the announcer and referee waiting for either of the two to show up. The announcer, a ferret, tried to hype up the hundreds of furs in the audience while wondering why neither of the two checked in around twenty minutes earlier. Olivia was meant to, but that was while she was sleeping off the leopard. And Cassie couldn't for obvious reasons... "Ladies and gentlemen, who's ready to see who the new champion is going to be tonight? Will it be the reigning champion, or the rising star? Marsupial or feline?" He yelled, waiting to hear the audience roar in response. "Speaking of which, where are they, anyway...?"
 
Almost as if it were on cue, Olivia at last came out from the right entrance, now wearing the same tight boxers and top along with a pair of red boxing gloves as she waved to her cheering fans. However, people curiously noted her surprisingly bulging stomach that sloshed around quite a bit as she walked... The roo hoisted herself up onto the ring to greet the announcer. "Hey! There's the girl I've been looking for, right on time too! But you look a bit... different. Pardon me asking, but did you gain a few pounds since your last fight?" He smirked a little, gazing down at her gurgling gut. This made Olivia sweat a little bit, but she quickly thought of a good response to his question. "Well, you see... I decided that I was a bit too lean for the fight. One hit on the hips from her and I'd probably be on the ground! So I decided to pig out a little bit before the fight to absorb a few more punches. I'll probably work it off me soon, though." She smiled, shrugging. "Hmm... Well, I guess that makes a bit of sense. After all, your competitor tonight has had a history over the past few weeks with one-hit knockouts." The announcer grinned, shrugging along with her. "Say, would you have any clue where she's at tonight, by chance?"
 
"I've actually got some bad news for any Cassie fans out there tonight... she told me she's not going to show up." She delivered, waiting for the crowd to gasp before carrying on. "I was actually talking to her earlier today, and she said that she wasn't really interested in being a fighter anymore!" Olivia laughed a little, grabbing her stomach with one hand as it groaned. Cassie must be done in her stomach, starting to go lower inside her as if to protest against the roo's speech. "I'm just as surprised as you are... She was doing so well, too! But I guess that's just how things go. I hope she has some good luck wherever she ends up. I think she told me she was looking for a more... *URRRRRP!* ...business-oriented career." Olivia stretched a little, looking to the shocked audience as the announcer continued where she left off. "...Well, you heard it here first, folks! Cassie quits, and Olivia wins the championship by default!" The ref raised her hand, and the audience gave a lot of cheering, and some booing from Cassandra fans in denial. "I guess I'll show up tomorrow to announce my retirement..." The roo thought to herself, as she received the trophy. It was a shame she had to win by utilizing such a dirty tactic, but you have to do what you have to do.
 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
The next day, Olivia returned to the wrestling center to reveal her retirement and clean out her locker in the same locker room she ended up eating Cassie in the day before. "Ooof, it was only last night, but it feels like it's been weeks since I took care of ya..." The roo said to her stomach, a deep growling rumbling throughout her lower region. "Ugh! I think I can feel you starting to cramp me up a bit... I'm going to assume that you're ready to make your great return, then." She continued, holding onto her gut as she almost immediately stopped clearing her locker to walk over to the women's restrooms, connected to the locker room.
 
The bathroom was clean, with four stalls up against one wall with the sinks on the other. Meanwhile, a female otter janitor was hard at work waxing the tiling on the floor, who Olivia quickly disregarded as she focused on the more prominent issue at the moment. "Making me clean these floors again... Who do they think they are? They're already damn spotless!" She complained to herself, without paying much mind to Olivia either. The roo quickly slipped into the first stall, closing it behind herself with her tail and locking the door. Just as fast, she dropped her black shorts to the floor and sat down on the white porcelain, her bowels roaring to life with a foreboding growl. It was at that point that Olivia realized that this might not have been the best place to release her rival.
 
However, everything was already moving so fast that it became an 'any-port-in-a-storm' situation, and she just had to let everything happen. And once she raised her tail over her shoulder to hold onto and let out a slight groan, it certainly did. Her stomach's bloating shrank slowly as she unleashed a spluttery outburst of gas that instantly tainted the once pristine air of the room, causing the janitor to gag on impact and cover her nose with her shirt, shuffling through her bucket to find some air freshener. "Shit..." she groaned once she came up empty. Her exclamation could also be applied to the events in the near future, as Olivia finally felt the blockage inside of her ready to come out.
 
The same puckering tailhole she used to take in Cassie was ready to release her, the hole yawning wider and wider to push out the first of the leopard's legacy. Olivia exhaled loudly from the feeling that was making her knees buckle, as the beginning of a thick, brown log of rooshit squelched out of herself. It was a very noisy release, as the snake pushed out longer and longer underneath her until it broke off, the foot-long behemoth staining both the clean white porcelain and the clear water to a filthy brown. Pushing down on her gut and cringing, a bassy fart freed what seemed to be her gym shorts, torn and stained, onto the murky water before being covered by more mess.
 
The otter just watched in disgusted shock and awe at the roo disposing of her rival, only able to see her legs underneath the door. "What the hell did you even eat, miss?" She asked, before being interrupted by more grotesque noises. From there, it appeared that the immense load of former snow leopard was displacing too much of the water inside the toilet, Olivia grunting and sitting up a bit as the tainted water spills onto the floor. "No, no, no, no... Not the floor!" The otter complained in anguish, powerless to stop her as more filthy splatters and splashes sound throughout the room.
 
Olivia was feeling just about empty of her former competitor as the mess itself became too much for the thing to handle, a few logs piling over the rim and draping over the side of the bowl before winding up onto the floor for the horrified janitor to see. There was clearly some white and black tufts of hair in the mess, and she even saw parts of a shirt slog onto the floor. Finally, there was the last bit of blockage that Olivia had to spread her ass manually to force out, audibly straining. Then, the fanged skull of the leopard descended onto the mess over the toilet with a *SPLUT*, sinking down into it.
 
The roo took a moment to catch her breath, looking back at the damage with a blush as she grabbed the roll using her tail to wipe herself. Afterwards, she stuck the dirtied paper into the pile itself and unlocked the door to step out, making sure to close the door behind her. The now furious otter saw that her stomach had decreased by around half the size as it was when she first walked in, fuming over all the damage as the roo washed her hands. "What... the hell... did you DO?" the janitor groaned, her head in her hands as she looked for anything she could use to clean the mess in her bucket. "Phew! Well, I think I clogged it. Sorry, and good luck with it~" She shrugged and blushed as she pulled the door to leave and forget about the whole incident. Afterwards, the otter pushed the stall door open and shrieked at the horrific sight.
 
All that was on Olivia's mind at that point was to get all of her things together, retire, and move onto something else. Maybe she'd just try doing MMA events at gyms for charity... Sounds a lot easier than this, and will probably net her a few more big meals if she's lucky.
