Work Text:

“Welcome to The Largest Gainer! I am your host, Skylar North, and I’ll be introducing our contestants for this long-awaited event!”

She says as she walks across the stage, her curvy figure evident in her tight golden dress, her platinum blonde hair resting on her shoulders. Audience members clap and cheer as she walks.

“But first!”

She sticks one finger out, silencing the fans.

“I’ll explain the rules!”

She turns around to face a giant screen, where a display of pictures and graphics appears. Intrigued “Ooos” and “Ahhhhs” ring out from the crowd.

“The game is to gain as much weight in one year! Our contestants will be living in the TLG mansion for the full duration of the next year, and they will compete in bi-weekly challenges!”

She spins back around to face the camera, her breasts bouncing from the movement.

“Whoever wins gets a prize, and whoever loses gets a punishment. So you’ll have to do your best, ladies!”

The audience cheers again, as Skylar gets a touch more serious.

“We will do monthly weigh-ins to check their progress, and whoever weighs more at each one gets a bonus prize. And whoever has gained the most weight by the end of the year…”

She pauses, the audience silencing.

“Wins ten thousand dollars for every pound they gain!”

The crowd erupts in applause and excitement, many having stood up out of their seats to cheer louder.

“Now, I think it’s time to meet our lovely ladies. Are you ready?”

A resounding sound of agreement resonates from the stands. Skylar points to her left dramatically, her whole body shifting.

“From the Big Apple, New York City itself, is Olivia Moore!”

A fit and busty blonde woman in fitted black bikini cut underwear, plunging at the top and cheeky in the back, walks on stage, getting loud cheers from the fans. She struts up to her designated spot, spinning around with a confident look on her face.

“Olivia’s ready to go from fit to fat for fame and prize money! If she wins, she plans to document her weight loss journey, becoming the fitness influencer she aspires to be!”

The audience cheers at Skylar’s words, while Olivia puts one hand on her hip and one behind her head, striking a sexy pose. Skylar dramatically points to her right.

“Now, it’s time to meet our other contestant! From the small town of Mapleville, Michigan, is Anna Baker!”

A somewhat slim brunette woman with a flabby midsection walks onto the stage in gray boyshort underwear and a more modest bra. Her chest is smaller than her competitor’s, but her ass is bigger. The audience cheers excitedly as she walks to her spot, visibly embarrassed.

“Anna just got down to the skinniest she’s been in years, but she’s ready to gain it all back and then some! If she wins, she wants to live a comfortable life back home!”

The fans cheer and clap, excitement in the air. Two stagehands quickly pull curtains from in front of two parts at the back of the stage, revealing two scales.

“Now, to start off the competition, please step on the scales, ladies.”

They nod, walking over to the large metal scales, both of them stepping on, making sure to stay facing the audience. After a moment, each scale beeps, and a number is displayed on the large screens above them.

“Anna starts the competition at 123 pounds! And Olivia starts at 126 pounds! With that, the competition begins now!”

The crowd thunders with applause, while Anna and Olivia are guided off stage and to the TLG mansion. Skylar waves to the fans as she walks off, and the cameras cut as Anna and Olivia are driven over to their new home for the next year.

~~~

After getting their rooms set up and some behind-the-scenes stuff, the first challenge begins. Both girls get dressed, Olivia in denim shorts and a crop top and Anna in stretchy sweatpants and a loose sweater, before they’re taken to the event center. It’s a large building with a raised stage, a table with two chairs front and center, with a backdrop with a scoreboard behind it. A pile of glazed donuts sits in front of each chair, each stack so large it’s hard to count just how many there are. Anna and Olivia are brought to the front of the table as Skylar walks on stage, earning cheers from the audience. The cameras start rolling.

“Hello everyone! Welcome back to The Largest Gainer! Today, we’re having our first challenge. A donut eating competition!”

The crowd cheers at her words as she walks up between the contestants.

“But first, ladies, would you mind showing off those little bellies of yours? It’ll make for a great before-and-after shot.”

Olivia unbuttons her shorts and opens them up to show off her tight core, while Anna pulls up her sweater to expose her loose midsection. Skylar crouches down between them, getting eye level with their navels.

“Aren’t these little bellies just the cutest? So flat and firm.”

She gently pokes Olivia in the stomach.

“Or, well, you’ve got a little something there, Anna.”

She turns and pokes Anna’s stomach, making her cheeks redden. Standing back up, she puts her hands on her hips.

“Alright, we got the shot, now let’s start the challenge!”

While the fans clap and cheer, Olivia and Anna, with their stomachs put away, walk around either side of the table to sit down.

“Tell me whenever you’re ready, girls.”

After a moment, they speak up almost in unison.

“Ready!”

Olivia speaks first, her voice loud and firm.

“I’m ready!”

Anna follows right after her, notably quieter. Skylar nods.

“Three! Two! One! And go, ladies!”

A buzzer sounds, and Skylar shoots her hand up with excitement as the timer begins. Olivia and Anna start eating, shoving donuts into their mouths. The fans cheer, staring up at the screens showing different perspectives of the girls stuffing their faces.

“Our beautiful contestants have a maximum time limit of twenty minutes, but if they don’t eat a full donut after two minutes, they are tapped out!”

Their eating pace is quite fast at first, each eating a donut every few seconds. Olivia clears her first dozen before Anna by two donuts, but they both clear their second dozen around the same time. The camera pans to their sides, showing rounded bellies sticking out from their figures.

As the minutes pass, both getting full, their pace starts to slow. Olivia slows more than Anna, having to pause to wrestle with the button on her shorts. By the time her gut is freed, Anna has outpaced her by a dozen donuts. Deciding to skip sips of water to try to catch up, Olivia finds herself reaching her stomach’s limit fast. Anna continues on steadily, her pace slower than before, but faster than her competitor.

Olivia, bloated beyond belief, leans back to massage her gut, while Anna continues to stuff donuts into her mouth. Her hands slide over her firm belly, her top having risen minutes ago. She takes short and shallow breaths as her timer ticks down. As she chews, Anna looks at Olivia and smirks. The audience begins to chant along with the countdown, and Skylar joins in.

“Five! Four! Three! Two! One!”

A buzzer blares, and the timer stops, while the fans clap and cheer.

“We have a winner! Olivia, having eaten 39 donuts, was disqualified after not eating for a full two minutes! With 57 donuts eaten in 12 minutes, Anna has won the donut-eating challenge!”

Anna pumps her fist in the air, smiling wide with icing on her lips. The audience applauds her, chanting her name with tangible excitement.

“Alright, girls, please make your way to me for the after photo!”

Anna braces herself against the table, pushing down with her arms to lift herself out of the chair. Both hands resting on her full belly, she slowly walks up to Skylar. Olivia tries to get up, but is too full. She tries and tries, tensing her abs and pushing her hands down against the chair, and with one forceful push from her legs, she stumbles out of her seat. Groaning and rubbing her gut, she walks up to Skylar. Once both girls make their way to the front of the stage, Skylar turns to face them.

“Anna, belly out, please.”

Anna nods, pulling up her loose sweatshirt to expose her big, rounded gut. Skylar steps between them, crouching down to be face level with their tummies.

“Wow, girls, you’re both looking big!”

She turns to face Olivia, reaching out to place her hands on her firm, overstuffed belly. She rubs her hands over it for a minute, eliciting moans and groans from Olivia.

“You didn’t win, but you ate a ton. Just train your stomach, and you might win the next eating challenge.”

Skylar lightly smacks Olivia’s belly, making her moan louder.

“Have anything you’d like to say?”

“I… I’m so full…”

Skylar pauses, waiting for her to continue, but she just moans, rubbing her belly.

“Okay, thank you! Good job, Olivia!”

She starts to clap, and the fans follow suit, cheering and applauding for her. After a minute, they settle down, and the attention shifts to Anna. Skylar turns to face her, placing her hands on Anna’s stomach. Skylar glides her hands over it, as Anna breathes heavily.

“Anna, you did amazing. You won the first challenge of this show, which means you get a live-in feeder for the next two weeks!”

Claps and cheers erupt from the crowd, but settle down as Skylar continues.

“You’ll get to sit and relax as you’re fed whatever you desire all day, not having to lift a finger.”

Anna smiles, wincing a little as Skylar presses her hands into her ball of a gut.

“So, Anna, any words for the fans?”

She nods, collecting herself a little before speaking.

“Yes, I- *BUUUOOOORRRPPP*.”

Anna hides her reddening face in her hands, while the fans start to clap and cheer.

“Excuse me…”

She mutters, earning approving applause.

“Wow, Anna, that was quite something. You must feel better after that, no!”

Anna, cheeks redder, nods.

“Alright, alright. You’re free to go, girls. Go rest up and start eating to gain some weight!”

Skylar’s claps trigger cheering from the crowd, as the two bloated contestants are guided offstage and back to the mansion.

~~~

Over the next year, Olivia and Anna were more gluttonous every single day than many people ever will be. Every action was centered around one idea, ingesting as many delicious calories as possible. Every two weeks, they competed in eating contests, the winner flipping back and forth between the two of them. And every month, they weigh in on stage to measure their progress.

In the first month, Olivia gained 21 pounds, and Anna gained 19. By the second month, their scores tied, as Anna gained 21 pounds, weighing 173 pounds, while Olivia gained 19 pounds, weighing 166 pounds. But from there, Anna took the lead, gaining 22 pounds in the third month, while Olivia gained 17. Month four, they both passed the 200-pound milestone, Anna weighing in at 218 pounds, 23 gained, and Olivia weighing in at 203 pounds, 20 gained.

Five months in, Olivia gained another 18 pounds, while Anna put on 26. Halfway through, Anna was up to 269 pounds, gaining 25 pounds that month, as Olivia was up to 243 pounds, gaining 22 pounds that month. Seven months along, Olivia gained 24 pounds, while Anna gained 27 pounds. Eight months in, Anna made it past the 300-pound mark, at 327 with 31 pounds gained, one pound each day that month. Olivia just barely missed the 300-pound threshold, gaining 27 pounds and reaching 294 pounds.

In the ninth month, Anna gained 30 pounds, while Olivia gained 26, reaching past the 300-pound milestone. Ten months in, Olivia gained 29 pounds, weighing in at 349 pounds, and Anna gained 32 pounds, weighing in at 389 pounds. After eleven months, Anna reached the 400-pound mark, gaining 33 pounds that month, while Olivia gained 31 pounds.

~~~

“Ladies and gentlemen, welcome to the final day of The Largest Gainer!”

Skylar says as she walks onto the stage, her golden dress clinging tightly to her curves. The fans clap, cheer, and chat, erupting with excitement.

“Today we are doing the final weigh-in, where the winner of this big competition will be decided! Whichever girl has put on more pounds in the last year, wins $10,000 for each of those pounds!”

The audience cheers again, as Skylar smiles.

“Come on out, Olivia!”

She snaps her fingers, signaling the lights to shift to her left. Olivia walks on stage, wearing a low-cut bralette and a cheeky thong, both black and lacy. Her breasts are huge and soft, jiggling gently as she walks. Her belly, which her boobs rest on, is round and big, hanging down enough to partially hide her crotch. Her face is round and soft, her arms and legs are thick and plush, and her butt is fat and jiggly. She struts onto the stage, showing off her curves with a smirk, before stopping at Skylar’s left.

“Olivia! Wow, you look great. Mind if I…?”

Skylar trails off, her hands near Olivia's breasts. She nods, and Skylar grabs handfuls of them.

“Unreal, these are amazing. Some of the biggest breasts I’ve ever seen, and you grew them in just a year.”

The audience is quiet, as transfixed on Olivia’s assets as Skylar. Skylar glides her hands down from Olivia’s chest to her belly, eyes widening as her hands sink into her softness.

“And your gut doesn’t disappoint either, Olivia. So round and jiggly.”

Skylar shakes it with her hands, making it wobble like pudding. Olivia’s cheeks are touched with pink as Skylar spins her around, showing off her butt to the audience.

“You’re top-heavy, but this ass is nice and fat too. I’m sure you’re proud, and you should be.”

Skylar grabs handfuls of it before pulling away to spank her lightly, making it jiggle wildly. Skylar watches as the movement spreads to her back fat and her thick thighs, almost in a trance.

“Alright, thank you, Olivia.”

Skylar clears her throat after a minute, standing back up straight. Olivia looks over her shoulder, striking a sexy pose at the camera, riling the audience back up.

“Okay! Anna, come on out!”

Skylar snaps, silencing the cheering crowd and focusing the lights on the right in the same moment. Anna walks on stage wearing a matching set of pink lace panties and a bralette. Her boobs, much smaller than Olivia’s, are still each nearly the size of her head, though they’re quite wide. Her doughy belly is huge, sticking far out in front of her, and hanging down to fully hide any trace of underwear from the front. Plump love handles spill over her waistbands and rest against her side rolls, which spill out from the hem of her bra. Her hips are very wide, and lead to a huge, wide, jiggly butt. Her legs are thick and doughy, pressed together down to her knees, which are softly covered in fat. Her arms are fat and round, her face is rounded out by a double chin and chubby cheeks, and every other feature is soft, fat, or doughy. She waddles up to Skylar’s right, hands rubbing over her belly as her cheeks turn red.

“Oh my, Anna, you are huge!”

Skylar steps towards her, immediately sinking her hands in Anna’s doughy belly.

“Woah, girl, you feel like a big marshmallow. You grew yourself a great tummy.”

Skylar slides her middle and ring fingers on one hand into Anna’s navel, playing with her belly button. After a minute, she pulls away, leaving Anna red in the face and biting the corner of her lip. Skylar grabs Anna’s boobs gently, fingers pressing into softness.

“These feel great, too, Anna. Your figure is lovely.”

Skylar spins her around, not waiting before smacking her hands against her giant butt cheeks.

“And this ass, Anna. Oh my goodness, it is giant! You should be proud.”

She nods, red in the face but smiling. With another spank, leaving her jiggling, Skylar stands back up to face the fans.

“Now, without further ado… Are you ready for the final weigh-ins?”

She asks the audience, who respond with a booming cheer. With a wave from Skylar, Anna and Olivia walk to the scales.

“Whenever you’re ready, ladies, go ahead and step on the scales.”

They each step on the scale, the metal creaking a little under their weight. Facing the audience, worry on both of their faces, they wait for the scales to ding. After the longest twenty seconds of their lives, they beep, and the numbers are displayed on the screen.

“Olivia, you weigh 412 pounds. So you’ve gained 32 pounds since last month, and 286 pounds in total.”

She pauses.

“Anna, you weigh 448 pounds. So you’ve gained 32 pounds since last month, 325 pounds in total, and you’ve won the competition, winning 3.25 million dollars!”

The audience erupts in celebration as Anna raises her arms in the air, smiling wide. Skylar waves her up, and she waddles up to the front of the stage. Skylar places a donut-shaped gold medal around her neck before hugging her.

“Olivia, you come up too.”

Skylar says, getting the frowning Olivia to walk up to the front of the stage.

“Now I know you didn’t win, but you still gained all this weight. And I think you still deserve a prize. Right?”

She turns the question to the audience, who cheer in agreement. Olivia’s face starts to light back up as Skylar turns back to face her.

“For your very big effort, you’re winning one thousand dollars for each of those extra pounds you put on. So you’re going home with $286,000!”

Olivia smiles wide and cheers, as the fans do the same. She jumps up a little, making her breasts nearly bounce out of her bralette. As the applause calms down, Skylar puts her hands on her hips.

“Alright, ladies, now that your prizes are sorted, I’m sure the fans would love to know what your plans are. Olivia, with your new money and extra pounds, do you still plan to drop the weight and become a fitness influencer?”

Olivia smiles, running her hands down her front.

“Well, I really loved that modeling challenge we did. And I’d hate to give up boobs like these so soon. So I think I’ll start modeling, and keep this weight for a little longer.”

The audience claps for her, as do Skylar and Anna.

“I’m sure there’s plenty of recruiters looking for sexy new talent like you, so that’ll be a breeze. I’ll be wishing you luck, Olivia.”

Skylar says with a smile, before turning to face Anna.

“Alright, our big winner, what’s your plan?”

Anna sighs contentedly, resting her hands on her tummy.

“Still the same, I want to live a peaceful life without stressing about anything. And getting to eat whatever I want without consequences.”

Fans applaud her, as do Skylar and Olivia.

“Well, that sounds lovely.”

Skylar takes a deep breath.

“And with that, The Largest Gainer has ended! Congratulations, girls, go get yourselves something to eat!”

Surrounded by cheers and applause, Skylar, Olivia, and Anna share hugs before heading off stage. Olivia, ready to prove herself as a model, and Anna, ready to live a pampered, well-fed life.

Notes:

This one was pretty unique and fun to write! I wrote the first part of this, then scrapped it and tried to come up with a different idea for a little while, but ended up coming back to it since I couldn't come up with anything better. I could have explored this idea in a much longer story (like going over each month, all the challenges, day to day in the mansion), but this is a short story thing, so I didn't lol. Maybe I'll come back to this idea one day idk. And since this story is number 14, that means I am 1/3 of the way done with the prompts! Kinda crazy, it feels like I just started this series, but that's just how time flies! Anyway, my next one is in progress, plus actually outlined (usually I don't outline, but I had the idea for this one and outlined it a bit ago). As always, have a great day! :D

Edit: I accidentally hade this set to show it to register led users only, but it’s fixed now!
