The bind of the bloated bubblebutts

When he'd fallen asleep, Morgana had been in Tokyo, he knew that. So then, why, now, was he somewhere he didn't recognize? He was in a fairly large room with four walls, one of which seemed to be entirely glass, the others being slightly off-white in color. The room looked about fifteen feet wide, and the ceiling, maybe ten feet up, had a large, circular grate in the middle of it. Past the giant window was a relatively featureless room, just a closed door, and a camera set up on a tripod, looking into the room Morgana was in. Only now did he realize that he was completely naked, not even having his mask for whatever reason! He barely paid that any mind, though, before noticing he wasn't alone. Across from where he'd woken up was a strange, white, glowing creature he'd never seen before, slumped against the wall similarly to how he'd been, himself. It didn't seem to be a demon, and certainly wasn't a Persona, so, hoping that it was asleep, Morgana cautiously crept over for a better look.
The creature was about the same size as him, and it - or, as it turned out, he - was naked as well. He had hooves instead of feet, three fingers on each hand, and what seemed like two sets of long, rabbit-like ears. This thing wasn't even close to anything Morgana had seen before! Suddenly, the creature started to stir, and Morgana nervously stepped back, not knowing whether they might attack him when they woke.
The creature's eyes opened, and he seemed startled for a moment, likely just as confused as Morgana was, before he spoke. "Where the hell... Oh! Um... Hi."
"Nice, I wasn't sure if you could talk! So, you don't know what's happening, either?"
"Ah, damn it, I thought maybe you'd have been involved with whoever did this."
There was silence for a moment, then Morgana reached out to help the creature get up. "Well, we're both stuck here, so we may as well get to know each other a bit. I'm Morgana."
The creature took his hand. "Ori.", they said.
"Right. Let's check the walls for a way out. We were put in here somehow, so clearly some part of them can open."
So, for a good few minutes, Morgana and Ori rubbed at the walls in silence, feeling for any kind of seam, though not noticing any. Eventually, Ori spoke up. "So... Where are you from?"
"I'm fr... Wait, do you hear that?"
They both listened for a moment, and indeed, there was a strange noise, too quiet for either of them to tell what it was. "The hell's that?", Ori said.
"...I think it's coming from that grate."
Both of them walked under the grate in the ceiling. Sure enough, the sound was louder, and... Continued getting louder.
Morgana started getting nervous. "Is...I-is that water?"
As if on cue, a torrent of water started flooding through the grate, crashing down on Morgana and Ori! The sheer force of it knocked them down, and they sputtered as they struggled to stand back up. Already, the water had reached their ankles, and was quickly getting higher!
The two didn't bother going back to checking the walls, instead running up to the window and banging on it as they yelled, hoping that someone in this strange place might hear them.
"SOMEONE GET US OUT OF HERE!"
"THE ROOM'S FLOODING, WE'RE GONNA DROWN! HELP!"
Soon enough, the water was at their necks, and they started needing to swim to keep their heads above it. Then, something occurred to Morgana. Immediately after falling asleep, he'd found himself in a strange place with a strange creature... "Oh, I figured it out! This is a dream!"
"...You're totally right! Why didn't I think of that?"
Their fear quickly melting away, Morgana and Ori resolved to have a good time with this dream while it lasted, happily swimming around the flooding room and splashing each other. They both puffed their cheeks and dove under for a moment, watching the massive amount of bubbles the water torrent was making.
Feeling a slight rumbling in his belly, Ori clenched his buttcheeks and nervously looked over at Morgana, seeing they were still focused on the bubbles. Hoping the splashing would be enough to cover the sound of what was coming, he relaxed and allowed the growing pressure in him to slip loose.
fblrblrt!
Ori froze up, blushing as a cluster of bubbles rose from his rear in an aquatic fart that was quite a bit louder than he'd anticipated, not having done much underwater farting in the past. He didn't need to look to know that Morgana had noticed, hearing their burbling laughter. "Hblahbla! Dobln't woblrry ablout iblt, wabltch!" Morgana turned around and bent forward, giving a good view of his own butt, before tensing up and farting out some bubbles of his own. Ori smiled, substantially less embarrassed, and swam back to the surface, Morgana following him.
The water was quickly nearing the ceiling, and while neither of them were scared, they both pretended they were. "Oh, gosh, this is terrible! We're almost out of air!", Morgana said. "Boy, it's a real shame that all we're gonna have to breathe soon is water.", Ori added. They both laughed, then took a deep breath just before the room fully flooded.
Even though the only air left in the room now was what was in the duo's lungs and cheeks, they still weren't scared, smiling at each other and letting themselves sink to the floor. Ori tilted his head back and blew out a few bursts of bubbles, eventually succeeding at getting one to be ring-shaped. "Oblh, thblat's neblat!", Morgana glubbed in response.
"Thblankbls, iblt wabls reblallbly hblard tblo fiblgurble oublt hblow tblo dblo thblat."
Morgana hopped up and started swimming about, blowing bubbles, with an occasional few slipping from his butt. Ori, meanwhile, slowly strolled on the bottom as he too intermittently farted out little spurts of bubbles. "Thblis ibls acbltualblly kiblnd oblf boblrinblg, noblw...", Ori complained.
"Yeblah, thblere isbln't mublch tblo dblo ibln hblere."
"...Hblold obln, umblmm... Moblrgablna, yoblur beblly seblems biblggeblr!"
Looking down at himself, Morgana confirmed what Ori had said. Indeed, his belly had expanded somewhat, and, looking over at Ori, it seemed like his had gotten bigger, too!
"Spbleak foblr yoblursblelf, fabltty! Yoblu beblen gublpinblg soblme wablterblmelblons, ovbler thblere?"
Unknown to the both of them, whenever either of them would bubbletalk, little bits of water would slip into their mouth and pour straight into their stomach, slowly bloating them out with each word they blubbed.
"...Mabln, thblis ibls abl reblallbly weblird drbleam...Webll, wble mably abls webll plblay arblounbld wiblth thblat whblile wble're hblere!" Ori opened his mouth and started drinking the water around him, his belly expanding a tiny bit with each gulp. Morgana did the same, but as the weight in his stomach slowly grew, he started having some trouble continuing to swim, until it was a real struggle to keep himself off the floor, frantically trying to swim upward but barely gaining any height. Eventually he gave up and let himself sink, his bloated belly jiggling and pushing out another bubbly fart as he landed.
Morgana and Ori each had their gut expanded to about three feet in width at this point, and as they sat down facing each other, Ori pushed his belly around a bit, before leaning forward and farting again, a small column of bubbles rising from behind him. Laughing again, Morgana did the same. The two went back and forth like this for a while, before they were interrupted by a heave of their chests. Up until now, they'd been paying no attention whatsoever to their lack of air, but their bodies finally decided to make the issue known.
Both of them puffed their cheeks up to the size of volleyballs, Ori covering his mouth as Morgana instead put a hand to his neck and voiced his predicament. "Dbl-dablmn iblt, nbl-nebled aiblr!" Ori uncovered his mouth for a moment, blubbed out "Mbl-mble toblo!", then covered it again. Knowing they were in no danger whatsoever, neither made any move to escape, but got up and started swimwalking around the room, trying to distract themselves from their need to breathe. Each contraction and heave would be followed by a small fart, bubbles trailing from both ends of Morgana and Ori's bodies as their cheeks started expanding farther.
About a minute and a half passed like this, the cheeks of the two of them starting to turn blue as they grew to be several feet wide, before Ori doubled over and tightly shut his eyes, both hands still pressed against his mouth as he soon fell to his knees. His chest started heaving even harder than it had up until now, forcing out muffled whines and bigger bubbly farts as Morgana came over to check on him, now having both hands on his own mouth. Ori opened his eyes slightly to nervously look up at Morgana, before closing them again and leaning forward as his cheeks got even bigger. "Obl-Orbli...foblcus-MMM!-obl-obln mble!" Morgana struggled against his instincts, forcing himself to talk despite the dire state his lungs were in, and moving a hand from his mouth to rub at Ori's convulsing chest. This got a brief smile from Ori, before his eyes went wide and his cheeks even wider, quickly inflating to the point that they touched the opposite walls of the room, before he couldn't hold on any longer.
MMMMMBLABGKPLPGLALBL!!!
Ori's cheeks rapidly deflated as a huge cloud of bubbles shot from his mouth, and an equally-sized one burst from his butt in his biggest fart yet.
PRBLRBLRLRBLRLBLT!
Just a moment later, he gasped hard, flooding his lungs with water as his belly visibly expanded a couple inches.
NNGHHUUUAAAGLGLR!
Morgana jolted back, returning his other hand to his mouth as he'd watch Ori choke and gag, farting with every loud, gurgling cough. Before long, he too reached his limit, cheeks inflating to the same degree Ori's had, then deflating as his body forced him to exhale and take a deep breath of the surrounding water.
For over a minute, all that could be heard in the flooded room was choking, gasping, and farting, said farts soon becoming the only source of bubbles as Morgana and Ori tightly hugged each other for as long as their inflating bellies would allow, hoping for any kind of comfort to ease the pain of drowning. Finally, mercifully, they started to calm down, heavily panting as they looked at each other. Ori tried his best to speak, though still being in the throes of drowning made it difficult. "I-iff th-glp-this issn...isnn't rreal -hulp- ww, wwhy doess -grgl!- i-it hhhurrt?" Seeing and hearing how much of a hard time Ori had with talking, Morgana didn't bother saying anything, just weakly shrugging.
At last, the pain in the duo's lungs disappeared, and a pleasant numbness began to spread through their bodies. It was beginning to feel quite good, breathing water, and both of them started getting aroused, dopey smiles forming on their blue faces. They tried to reach around their huge, five feet wide bellies to jack off, but neither had long enough arms for that. Having an idea, and still farting a good amount, Morgana laid down and shifted a bit so his fart bubbles rubbed at his dick as they floated up. "Mmnguuuoohhghh...", he moaned, getting Ori's attention and clueing him in on Morgana's technique. "...hhhehheh...c-clevverr...", Ori gurgled, positioning himself the same way and relaxing as his fart bubbles masturbated him.
This went on for about two minutes, Morgana and Ori occasionally hiccupping or gurgling a moan as their arousal, and their stomachs, continued to grow. At last, though, they could both feel an orgasm beginning to build up, their farting slowly intensifying, more quickly pushing them to their climax. Then, weakly humping at the water despite the weight of the water they'd drank...
"H-hrgh...Hrnghluuuup..."
They both came hard, spurting quite a few shots of cum into the water, the continuous farting becoming even more intense for those few seconds. Too soon, it was over, and neither of them had the strength to move any more. Bubbles still sometimes leaked from their asses, flowing around the sides of their enormous bellies that had become nearly seven feet wide.
"...hglh...hh-heyy Orri...ifff thhiss isss...-hic-...r-rreaal...i-i...donn't rrreally mm...m-minnd dyyinngllikhe th...thhh..." Morgana tried to talk, but it was almost impossible with how drowned he was. Still, satisfied that he'd probably gotten his point across, he closed his eyes, shuddering slightly as he passed out with one last fart.
Ori couldn't get a response out, not having as much willpower as Morgana, but he certainly tried. "gl-gkh...bblrrgl, hurgh..." Even he wasn't sure what he'd tried to say, losing consciousness moments later.

BEEEP BEEEP BEEEP!
Morgana woke with a start, finding himself back home. Oh, thank god, it really was a dream... Shutting off his alarm, he laid in bed for a while, thinking about the strange dream he'd had. Man, I'm kinda gonna miss that Ori guy, he was cute. As he rolled onto his side, he noticed a flash drive next to him. It had a label: "Morgana + Ori".
Morgana's eyes widened as the truth hit him.
