“Okay, time for a break!” Marin Kitagawa threw her pencil down on her desk and pushed her homework away, leaning back in her chair and stretching. She’d been studying for a whole twenty minutes, that warranted a twenty, maybe thirty minute break! Never mind the fact that this was her third break tonight already. Gojou had probably spent more time badgering her to do her homework than she had actually spent doing it so far, and everything she learned was doing its best to leave her head entirely as she pulled out her phone and started mindlessly tapping away.
Unfortunately for Marin, eager for an escape from her tedious homework, she’d pretty much exhausted her options for distractions already. She’d checked all of her socials, lovingly gazed over Juju’s latest cosplay shoot, uploaded a few selfies, and texted Gojou to see how her next costume was coming along, only to start sweating when he instead asked her how her homework was coming along. Curled up on her seat in her pajamas and a hoodie thrown over them with her phone resting on her knees, occasionally spinning herself around, Marin mindlessly scrolled through her phone’s app store. If nothing else, it was amusing to see what junk there was floating around.
Marin scrolled past gacha games, dieting apps (embarrassingly frequently appearing thanks to the consequences of her eating habits), and services she’d never use, eyes glazing over until she settled on one particular simply named title: “Transformation App”. She tapped on it, reading its description. The app boldly claimed to, as the name implied, transform the user using a number of pre-set options. The icons and screenshots of it were loud and tacky, which would have instantly turned off any sensible person, but luckily for the app’s developers, Marin was exactly the kind of gal who was into that kind of tacky, sparkly presentation.
“Change your body in a variety of fantastic ways… Sounds totes hilarious!” Marin smiled, hitting install on it. She assumed that it was just another photo-editing app, one that would distort a selfie to make her look fat or thin, or edit cat-ears or something onto her. She couldn’t wait to send one to Gojou! Besides, it didn’t really matter what she was doing, as long as it stalled out the clock until she had to go to bed instead of doing more homework. The app was installed in seconds, Marin opening up the gaudy app and scrolling down its various options, most of which were confusingly named.
“Glutton Goddess? What’s that supposed to mean?” She raised a painted eyebrow at it, before snickering. One of her co-workers had called her that once! Deciding it on the spot, she selected that option, which brought up another screen asking her long she wanted to be “transformed” for. The default option was twenty-four hours, Marin frowning at it. Was she supposed to only be able to use it once, then have to wait unless she paid for the full version? She dragged it down to six hours, the lowest option, and pressed the large “transform” button at the bottom.
“Uh, hello? I didn’t even take a photo yet!” Marin was confused again when it simply read “Transforming User… Step One…” and nothing else. She pouted and leaned forward to put her phone down on her desk in front of her. What a lame app! It didn’t even do any…
Marin’s thoughts trailed off as she stared at her arm. Hadn’t she been wearing a grey hoodie a moment ago? Now her arm was bare, save for a long golden bracelet curled around her wrist. Her eyes traced her arm up to her shoulder, where a thin golden band was also placed around her bicep. Inevitably her gaze reached her chest, where all she could see was her bare cleavage, exposed for the world to see!
Marin shrieked and jumped out of her seat, shrieking again when she saw that not only was her hoodie and pajama top gone, but also the cute shorts she’d been wearing!
“W-w-w-when did I get naked!?” Marin exclaimed in utter confusion, waving her arms around until she realised that she wasn’t completely naked, just mostly naked. Her nipples were covered by large golden pasties, adorned with large round pink diamonds that made it practically as lewd as if she’d been completely uncovered. Her modesty was preserved by a matching pink loincloth that reached down to her knees but was tantalisingly thin, while her shins had large ankle bracelets matching her arms. Her hips had large golden hoops with dangling pink diamonds hanging from them attached to her loincloth’s loop, and she noticed a similarly encrusted necklace to complete her image. She turned her head slightly, noticing that at some point her hair had been done up in a high ponytail, yet more gold holding it up.
“Huh? What? Magic? Huh?” Marin’s poor brain started to overheat, a clueless smiled plastered on her face as she stuttered. “Oh, I see, the app was totally real! That makes perfect sense!”
Marin slowly wandered over to her room’s mirror, posing in front of it for a second, something befitting her sexy vaguely Egyptian, or at least pop-culture Egyptian, theme. It kind of reminded her of certain anime characters she liked. She did look kinda good like this, she thought as she blew herself a kiss, then froze.
“No, that doesn’t make sense! Omigawd!” Marin squealed with her hands pressed against her cheeks, snapping back to reality. “I totes for real turned into a Glutton Goddess! Whatever the heck that means!”
Marin paused, split between totally freaking out and totally noticing a detail not adding up. She got the goddess part, but where did the glutton come in? Marin’s quest would immediately be answered as unbeknownst to her, her still lit-up screen changed slightly: Step Two had begun.
“W-w-what am I gonna tell Gojou…” Marin mumbled, still shocked and scatterbrained, when she noticed something in the mirror. Was her belly kinda pudgy right now? Like kinda hanging out and drooping a bit?
“And after all that dieting!” She moaned, kneading her flabby gut with her hands. It had totes not been this big before! To make things worse, her arms seemed kinda chubby too! And her thighs! And her waist, those were totally love handles starting to form! And her face, it had always been untouched by her overeating, but it seemed a bit wider than usual…
Marin let go of her gut, which flopped out, clearly a large pot belly at this point. She turned to the side, noticing that it was definitely noticeably distended, and her butt was sticking out further than usual. And was it just her, or was it getting bigger? Could it be, she went pale and slowly realised, that she hadn’t slipped on her diet, and that she was only just now getting fatter? Could it be that the app was…
Marin’s revelation was poorly timed, as her realisation was met with her belly surging forward, exploding outwards like a wave of fat sagging past her waist and downwards until it obscured the top of her loincloth. Her big butt had a similar reaction, Marin yelping as she felt it double in size, wobbling as she whipped around to see herself from the front, having to back away as her belly nearly pressed into the mirror. She felt her flesh press against her bracelets as her slender arms became anything but, dainty fingers becoming thick sausages as her arms filled out, biceps becoming thicker than her head and drooping under their own weight, the bracelets squishing and slightly indenting the flesh around them. Her slim, beautiful face’s distraught expression became even more so when it began to blow up like a balloon, rounding out as her cheeks turned cherubic, feeling her neck squish from the second chin it had obtained. Her hips expanded outwards until she needed to take more steps back to fit within her mirror’s thin frame, her hips doubling, then tripling as her weight added on hundreds of kilos in mere seconds, nearly filling out the loops as her thighs squashed together, no matter how far she broadened her stance. Her hips several heads with from her shoulders, Marin looked like she could barely fit through her bedroom’s doorframe, and had no idea how to react with anything but bewilderment as she cupped her biggest growth: her breasts that had filled up like she they were water balloons attached to a hose, always her most impressive feature, now easily twice the size of her head, surprisingly round even as their weight necessitated that they sag down to rest atop her engorged gut. Her nipples had engorged to an appropriate matching size, but the bejewelled pasties that covered them seemed to have grown to match, indicating just how puffy they were underneath.
“Omigawd, I’m so fat… Gojou, don’t look…!” She groaned, feeling like she was in a dream, hands tracing her squishy body as she gawked at herself in the mirror, tilting her head as she was transfixed by her chubby, kinda cute obese face, watching her cheeks droop slightly. She lifted up her gut and let it drop several times, hypnotised by the weight and flopping motion of what was now undeniably her own body.
“So I’m fat now.” She stated the obvious in a matter of fact voice, still dazed. “What now?”
Her question would be answered as her phone read “Step Three…”. She heard a rumble from her belly, her eyes falling downward to her navel, where something very odd seemed to be happening. Something large had sprouted on her belly when she wasn’t looking, a large, wide, red, and glossy lump with a colour that reminded her of her favourite pink lipstick. In fact, the whole thing reminded her of… lips? When she touched it, it felt exactly like her own, except super-sized. It even had a fold in the middle. It wasn’t quite as wide as her saggy breasts, but it was still noticeably huge...
Her stomach rumbled again, Marin feeling kind of hungry. Like, hungrier than usual. As if answering a call, she heard a slightly slimy, sliding sound, and turned pale once again as she watched the lump on her belly have something slide out from between it. Was that a.. No, it couldn’t be, but it looked just like a.. Tongue!? And yet, whether she denied it or not, it was a tongue, a giant tongue that slid out from her belly-lips and hung down past her drooping gut, saliva dripping onto the floor. It even had an enormous stud piercing, which she would later realise was mirrored on her regular tongue. Marin’s jaw dropped, her normal mouth going wide as it seemed to be unconsciously mirrored by her second lips, opening up to reveal a huge set of shiny white teeth, Marin able to see an entire mouth in there as her gut practically split in two. Then, once again, she screamed, her second mouth thankfully not mirroring that particular action.
“Gross, gross, gross, gross, gross!” Marin moaned, sucking her belly-tongue back into her gut-lips, which was an equally gross thing to do, but was better than having it out. She stumbled backwards, trying to flee her own shocking body, moving awkwardly and clumsily in her unfamiliar and huge body crying out as she bumped over the small table in the middle of the room, her eyes reflexively closing as she prepared to slam down and shatter it with her new obesity… only for the impact to never come. She slowly opened her eyes, staring up at the ceiling, feeling like she was lying down, but not. She turned over, rotating her entire body with ease, feeling her heavy flab fall sag consistently towards as she found herself staring down at her desk. Then, she put two and two together. She was floating! Flying! One or the other!
She flailed around a bit, trying to figure out how to land, before willing herself to slowly drift over to an open space.
“Goddess, huh?” Marin laughed at the absurdity of it, helping her calm down a little. She looked at her mirror again, seeing her huge tongue loll out, grimacing a little and forcing it back in, finding it surprisingly easy to control, experimentally opening and closing the mouth. It was gross, to be sure, but it wasn’t any stranger than the rest of her transformation. Between getting nearly naked, then fat, then a huge second mouth, then flying, the whole thing was so absurd she found herself giggling uncontrollably. The app was real! Who would have thought? She was fascinated by how her body squashed and stretched as she more calmly examined herself in the mirror, a bold new look for her. Was it wrong if she felt she looked kinda cute as a total fatty? She lifted herself up into the air and floated over to her desk, remembering to check the app.
It simply read “Transformation complete: time remaining:” and then had a clock ticking down five hours and fifty-seven minutes remaining. So after that, she’d go back to normal? She breathed a sigh of relief. Thank god! If it was temporary, then it was, as shocking as it was, harmless. Marin couldn’t help but laugh again, a bit shakily, still in a bit of shock at magic being real and her sudden transformation. What else could she do with this app, she wondered…
Her stomach rumbled again, echoing across the room as her tongue lolled out, licking her oversized lips. Marin had felt hungry before, but now she was positively ravenous, and felt an overwhelming compulsion to feed herself, now that she had calmed down a little. Too hungry to even try to float again, she waddled out of the room, her hips rocking and wobbling with each step as she just barely made it through her door frame without getting stuck, the floor thumping with each footstep as she made her way to her kitchen, then her pantry. She grabbed some snacks, a few bags of chips she had been saving, and ripped them open, her second mouth opening wide as she knew what she had to do; she poured the entire bag into her gut-mouth, feeding her stomach directly as it chewed then swallowed. She did it with the second bag, devouring the whole thing in an instant. But of course, it did little to satiate her hunger, so she moved onto the fridge. In went a bento from the nearby convenience store, some onigiri as well, then the properly cooked meal Gojou had made for her, then tomorrow’s breakfast as well, then lunch. When she ran out of prepared meals and was still hungry, she began to shovel in whatever ingredients she could find that could be eaten raw, her stomach-mouth chewing and swallowing with endless greed.
When her storm of gluttony was over Marin fell back, catching herself mid-air before her pillowy butt hit the kitchen floor. She had just exhausted everything edible in her house, but was still hungry! Luckily, she thought with a smile, she had just the solution for that. As she ate, and satisfied her gluttony, her sense of shame and embarrassment over her body seemed to fade. She felt hungry and powerful, and didn’t mind who saw her like this. She floated back over to her bedroom to retrieve her phone, bringing up a certain somebody’s number.
“Hi, Gojou?” She said with an unrestrained smile on both of her lips. “I was wondering if you could, like, come over and cook dinner for me, I’m really starving right now…”
