Yui tried to suppress a belch as she pulled her school shirt back down over her belly. It wasn't always this big, but recently, she's been gaining weight faster than she had realized. 
"What could have caused this?" she wondered, while taking another bite of her bacon cheeseburger. She had already polished off her salty fries and extra thick milkshake. After swallowing the huge hunk she just bit off and wiping the grease from her lips, she said
"Hey, girls. Do you think the school lunches have gotten kinda... unhealthy?"


Her two friends at the table with her were Yuzuko and Yukari. 


Yuzuko was a dumb pink-haired girl who always got over-excited at anything and everything. She was lying back, rubbing her huge gut sitting on her lap. She had to have been around 250 pounds, and almost all of it went straight to her perfectly smooth belly. She mindlessly jiggled and wobbled it in her food-induced daze. She had eaten two deluxe burgers and three orders of fries, after all. It was all she could do to moan in response to Yui's question.


Yukari was a ditzy young lady with long purple hair. She was extremely gentle and kind, and had a weak spot for sweets. She had just polished off her third fudge milkshake, and the dark liquid was dripping down her face onto her shirt, which was now stained a dark brown. Her belly was definitely chubby, but her legs were beyond fat. There was so much weight piled up on her legs that her plush thigh rolls were already developing cellulite. It was impossible to not get a clear view of her snow white panties.


Needless to say, these two weren't exactly the smartest pair.


"Are they really *uuuUUUUrp-* that bad, Yui? They taste so good," Yukari said, making no effort to clean off her chocolate covered face.


Yui looked down at her own body. She had blonde hair in two small braids, which rested on her unusually massive breasts. Her dress shirt was moments away from popping a button across the school cafeteria. They jiggled wildly every time she took a step, and sometimes even when she took a breath.


"Yeah. I think these meals are catching up to us. Just look around you!"


Still in a fast-food daze, the girls took inventory of all the students around them. It was an all-girl's high school, and this time last year it seemed that the student population was quite normal. Now was a different story. Every girl was at least overweight, most were obese. No one's shirts fit right, no one's skirts were long enough, and panty shots were a daily occurrence. 


It had to have been the school lunches' fault. These girls weren't just getting fatter, they were getting fattened.


After giving her friends a few more moments to recover, Yui lead the three of them in a march to the principal's office.


"Mrs. Principal! What is going on with these lunches?"


The skinny woman in a suit at the other end of the desk stared at them blankly.


"What's wrong? You don't like the school lunches?"


"Of course not! Just look at what they've done to poor Yuzuko!"


Yuzuko was hardly conscious, about to drift off into a food coma with her shirt rolled up over her tummy. The woman adjusted her glasses and thought for a moment before saying,


"Alright, alright, I understand. You're not the first to complain, anyways. I'll look into hiring a new meal provider, okay?"


Yukari's gentle eyes opened wide.


"Really? It's that easy?"


"Of course! Now please be on your way, class starts soon."


The three of them awkwardly shuffled out of the principal's office, not entirely sure what just happened.


"uuuuuuuuuooohhhhh... D-did we win?" Yuzuko stammered out.


"I think we did, I think we did!"
Yukari was happily hopping around, her massive legs causing the floor to creak.


Yui didn't seem as happy as her friends, because she wasn't quite as naive as they were. Something here was fishy, there's no way it could have been that easy. She had been mentally planning her student campaign over imaginary months, there was no way the problem got solved in about thirty seconds. But, after all, maybe she wasn't lying. Maybe she really would have the school offer new lunches...




Classes were now over, and it was almost time for the principal to head home. Today had been productive, she was able to get a lot done. There was just one last point on her agenda: new lunches. She flipped through a small booklet full of company names and numbers. After a moment of diligent searching, the name of a business caught her attention: 
"Coronary Catering: a heart attack with every bite! All prices currently 50% off." 
She decided to give them a call.






"Wh- what the hell is this?"
Yui was staring slack-jawed at the behemoth burger on the table in front of her. She counted at least eight patties, but it was difficult due to the unholy amount of cheese smothering it. The puddle of grease it was sitting in had made the bottom bun soggy and had slightly lost its form. The whole thing weighed over two pounds, and she ordered the small meal! The bag was still full of other fattening goodies, but she couldn't bring herself to look. She carefully picked up the sopping wet wrapper the burger came in and read the label: "Heart Attack on a Bun (S Combo)"
"Oh my God, they can't really expect us to eat something like this! It looks like a trainwreck, there's no way anyone would-"


She was cut short by the sound of her two impressionable friends mindlessly eating away. Halfway through her monstrous burger, Yuzuko's face was entirely coated with cheese. The grease had rolled down into her cleavage, permanently staining her shirt orange. Yukari was making huge gulps of her large "Diabetic Shock Shake," barely pulling back from her chubby face in time to catch a breath before diving back in. Yui couldn't believe her eyes, and disgust welled up inside her.


"HEY! FATSOS!"
She used her left hand to grab a huge chunk of Yuzuko's massive belly, and used her right hand to sieze one of Yukari's thighs under her tiny skirt. Immediately they squealed and looked up, temporarily broken out of their gluttonous spell. 
"What, what?" Yuzuko cried out, splattering grease as she spoke.
"Look at what you're eating! Do you want early onset heart failure?"
"Well, no, but..."
"But what?"
"Have you even tasted it? It's soooooo good!"


Yui eyed the burger. It looked even soggier now that the grease had been partially squeezed out under its own weight. It was difficult to look at.


"There's no way I'm letting that go anywhere near my mouth!"
"Don't knock it 'till you try it!"


Yui then turned attention to her purple haired friend.
"And Yukari, what do you have to say for yourself-"
Her rant was cut short when she noticed her facial expression. Yukari was blushing and fidgeting, unable to make eye contact. That was rare for her.


"Yukari, you okay?"
"Y-Yui... Your hand..."


Only now Yui realized the lewd place she had been gripping Yukari this whole time. She quickly pulled back her hand, leaving Yukari's impossibly soft thigh to ripple in recoil. After an awkward moment of tension, Yui regained her composure.


"A-Anyways, you guys shouldn't eat this stuff. It's clearly terrible for you, and they aren't even trying to hide it. It's important to watch your health, or else you'll-"


Again, Yui was cut off, but this time from a different sensation. While she was occupied with Yukari, Yuzuko had gotten her pudgy fingers around Yui's unattended burger. With the force of Hercules, she shoved it into her whining friend's mouth. Yui's eyes went wide as the salty and savory juices flooded her mouth and dribbled down her chin. The way it tasted was unbelievable, like it was made of pure delicious fat. She expected the copious amount of grease to be disgusting, but in fact, it was now her favorite part. She hesitantly chewed up the burger while Yuzuko pushed more into her mouth.


"See? Pretty good, right? I don't care if I gain a couple extra pounds, it's worth getting to eat this every day."
Yukari chimed in as well, saying, "Now that I've had this 'deeabetes' milkshake, I don't think I can ever go back... It's too sweet and too rich..."


Yui pulled her face away from her burger, and looked down at her cleavage. There was grease and cheese resting right on top of her tits. She was disgusted at herself for eating even just a few bites of that filth. But when she thought about how it tasted...


"Alright, fine. You guys win. We'll eat this slop every day until we're all so full of grease we're sweating it. Is that what you want?"


The other two girls looked at each other with wide food-covered smiles. In unison, they shouted,
"YES!"






A few months later, the terrible food had taken its toll on the three high schoolers. Yui had just made it to the cafeteria, wheezing and panting. Her shirt size had gone up and up, and now there were none that fit her. The white shirt she was wearing fit more like a tube top on her than s shirt. It had a cascade of grease stains on it, making one think that maybe it was an orange shirt with tiny spots of white. Her breasts were massive,  jiggling with every one of her labored breaths. Her puffy nipples were clearly visible under her struggling shirt, but she didn't care anymore. After all, she wasn't even the one in the worst shape.


Yukari was easy for her to find in the crowded cafeteria, because her massive ass was plainly visible for all to see. Her purple skirt rested on top of her booty shelf, leaving her stretchy snow-white panties on full display for everyone behind her. Her ass was so fat that even her cheeks had rolls on them. Her cellulite dimples were so large, you could fit your finger in them. She had become so wide, she couldn't fit through certain doors anymore. Every step she took caused a small earthquake around her, alerting anyone nearby to her presense.


Poor Yuzuko had it the roughest of anyone in the school. Her breasts were large, and her ass was round; but it was nothing compared to her two friends. Instead, she had a triple belly so big she was worried that it would soon touch the floor. It was constantly groaning and sloshing and churning, loud enough that it would interrupt class. Sometimes, all she could do was go to the nurse's office and belch until it quieted down. Clearly, this food wasn't agreeing with her digestive system.


After ordering their meals, the three morbidly obese teenage girls sat down at their usual table with a thud. There were permanent stains on the table from their past feasts. Even though the symptoms of their little dietary issue were now manifesting clear for everyone to see, they kept eating. And eating. And eating...


"huff, What did you get, Yui?"
"I'm not that hungry, so I just got a Deluxe Bariatric Burger with chili cheese fries and a medium soda."


The Deluxe Bariatric Burger was a new entree that just came out. In addition to cheese, it also contained patties of deep fried lard, and half inch thick strips of bacon. It was about as big as Yui's head, even with how her cheeks have filled out. The chili cheese fries came in a serving bowl. It was 'implied' to be shared with others, but they came with almost every combo meal, so everyone got one of their own. The sludge was so thick, sometimes it was hard to chew. And lastly, the 'medium' soda would be considered an XXL at most restaurants, big enough that you need to hold it with both hands. This was the smallest meal Yui had ordered in weeks.


Yuzuko was double-fisting her burgers like she usually did. She always asked the lunch ladies to add extra meat for her, which they always obliged. She wasn't really eating burgers anymore as much as she was eating huge chunks of beef. She always ate at least four during lunch, some days going as many as eight. In addition to her sides, of course.


Yukari had replaced the notion of "lunch" with "extended dessert." She would order one of every sweet on the menu, and then get about three more of the one she was craving the most that day. While the other girls would splatter meat and grease everywhere while they mindlessly pigged out, Yukari got icing and chocolate all over everything (especially herself).


The three noisily slobbed out while they devoured their less-than-nutritious food. Sauces, cheese, meat, cream, and huge squirts of grease flew out while they shoved their fat faces with what might as well be pure cholesterol. Their bellies swelled and tightened, but they just loosened their skirts and kept engorging themselves.


"Yuzuko, Yuzuko- you missed a patty."
Yukari used her gentle voice to point out a beef patty that had fallen in between two of her stomach rolls. She grabbed it out for her, and gingerly pushed it between her lips.


"Aren't you two all- *UuuUuuuuoorppp-* friendly with each other."
Yui huffed and continued eating her lard-covered fries.


"What's a matter, Yui? You jealous because... b-because... *UUUUUUUUOOORRRP-* I have a girl with a fat ass feeding me by hand?"


Yukari blushed. She knew she had a large butt, but she had never thought it would be seen as a desirable thing. Yui turned away, mildly embarassed by the teasing. Yuzuko slowly lifted her massive belly up off the chair, and waddled over to Yui.


"How about I give you a little attention too!"
Yuzuko grabbed the big bowl of chili cheese fries and lifted it up to Yui's mouth. She was too surprised to react, and within a moment she felt the salty, mushy liquid fill her mouth. Yuzuko and her chubby, wobbling chins were right in front of her.


Suddenly, Yuzuko's hand began roughly fondling Yui's oversized tits.
"Mfff!?"
Yui's mouth was too full to object.
"Wow Yui, you're even bigger than you look. What's in these things? Pure lard?"
While Yuzuko jiggled the massive breast in her palm, Yukari slowly waddled her unbelivable thighs over to Yui as well, and played with her other boob.
"W-Wow... S-so jiggly..."
Yui's brow furrowed in embarrassment. As retaliation, she took a huge slap on Yukari's slutty panties. It made such a loud sound everyone in the cafeteria turned to look.
"Hey, me too!"
Yuzuko absent-mindedly dropped what was left of the big bowl of fries right down Yui's cleavage. She began groping Yukari's ass, feeling the heft of each cottage cheese cheek. She tugged on her stretchy panties, giving her a wedgie and exposing even more ass flab to play with.


"MMmnnnnnhhh--"
She quivered and moaned, entire face going flush. She clearly enjoyed the feeling of having her massive weight groped and admired. Yuzuko enjoyed it too, offering her big meat-messy belly up to Yukari to squeeze and jiggle, which she happily obliged.


Yui watched her two friends manically groping and fondling each other, completely out of breath. She swore she saw a little wet spot on Yukari's panties when she turned around. She turned her head away and mumbled under her breath.
"Fine, have fun. I'll just eat by myself."


When she turned her head back forwards, her two friends had their faces mere inches away from her rack. Their eyes were full of hearts, and their mouths were drooling.
"Wh-what are you doing?"
They silently looked up with their obese, wobbly faces with big puppy dog eyes. Without needing to be asked, Yui already understood the question they were asking.
"F-fine. Just for a minute, okay? After all, you spilt my fries in between my boobs... S-someone has to take resposibility and clean it up!"


Within seconds, they had lifted up Yui's shirt that was wet with grease, and shoved their faces between her tits. (There was no bra in the way, because there was none that would have fit her.) Like vaccum cleaners, they licked and sucked her cleavage until it was spotless. They belched and moaned onto her chest. Right when they were about to pull away, Yui grabbed the back of their heads and shoved their faces each into a pillowy breast, poked by an erect but puffy nipple.
"I-I didn't say you could stop!!"




After this eventful day, their stuffing sessions became more and more intense. Filling each others' mouths with food, grabbing chunks of each others' huge guts, even reaching hands down each others' tight clothing. They had become all over each other, encouraging (and sometimes forcing) more and more meals to each other. After just a month, they had almost tripled their calorie intake. 


And it showed.




Walking became hard. Breathing became hard. Their bodies had become so overloaded with lard that doing anything required substantial effort. By now they were each about six hundred pounds, give or take a few rolls. Their table's sounds of ravenous gorging were still omnipresent, but in addition to their constant gasping for breath. 


Yui's breasts were so round and heavy they hung down to her flabby waist, and were so wide they spread around her sides. Yuzuko's stomach was monstrous, as wide as the newly installed triple-wide seats with her bottom roll still drooping onto the floor. Yukari's hips were too wide to fit through almost any door without turning sideways. Her fat began to not only accumulate in her ample behind, but also in her calves, becoming nearly as thick as her thighs.


"T-Too... Full..."
Yuzuko was gasping for air. She had just been lovingly fed twelve BeefBurgers by Yukari, each one right after the other. Yui helped out by topping her off with a Diabetic Shock Shake, which was still dripping out the corners of her mouth. Yui jumped into the action.
"Not yet you aren't! Not until you've finished the new Cardiac Killer Sandwhich."
The Cardiac Killer was a burger, but instead of beef, it was a five pound chunk of triple deep fried fat. It was so full of cholesterol, you could almost see it. 
"Open up, you obese hog."
Feeling the heart-wrenching "burger" slide between her lips made Yuzuko's eyes roll back. She was desperately rubbing the topmost rolls of her big red belly (because she couldn't reach the lower ones.) Her breathless gasps were quickly stifled by Yui's aggresive forcefeeding. Yui's arms were packed so fat, they wobbled from the slightest movements. After about a minute, the burger was half eaten, but Yuzuko got slower and slower. The hands rubbing her belly moved up to her chest.
"G-guys... I- *UUUUUUUOOOOOOOOOOORRRRRRRPPppppp-* I don't feel so good..."
Yukari seemed a bit worried.
"What's wrong? Is it your chest?"
"Y-yeah... Looks like all those Deep Fried Cholesterol Bombs are starting to get the best of me..."


Yui shoved the rest of the disgusting burger right into Yuzuko's already full mouth, and scoffed.
"Aww, you have a bit of fried food and your widdle chest hurts? Sometimes I eat three of those in a day, *uuuUUUUURP-*, how clogged do you think my arteries are?"
"Yeah, but you don't top them off with ten pounds of fried beef... My veins must be so full of lard..."
Yukari quietly piped in.
"Hey, my right arm went numb after I ate 10 Deluxe SugarRot Sundaes..."


Their complaining turned into a full-on argument.
Yuzuko: "Oh yeah? Well my blood pressure went over 200 the other day."
Yui: "Sometimes, for breakfast, I just chug a gallon of fryer oil."
Yukari: "I'm only eighteen years old, but I'll probably have a heart attack before twenty."


They continued on like this for a long time, but their annoyance soon turned to cheerful camaraderie. 
Yui: "Hahaha, don't worry Yuzuko, when your heart gives out I'll give you a ride to the emergency room."
Yuzuko: "As if you could see over your 'airbags'."
Yukari: "Ride with me, I'll take you to McDonalds!"
Yuzuko: "Thank you, diabetes queen! You'll have to stay outside though, your ass wouldn't fit through any of their doors."
Yui: "If their ice cream machine isn't broken, we'll make sure to order you enough to make it."
Yukari: "Mmmm... Make my blood sugar even sweeter!"


They giggled and teased one another about their rapidly declining health. Now, they felt more motivated than ever to keep eating, and eating, and eating; filling their bodies with overwhelming amounts of lard and fats.


"Overwhelming" really was the most appropriate word. Over the next few months, what were once three cute girls, soon became nothing more than massive sacks of congested fat in the school's makeshift bariatric ward. The school had created a special room for these three, to keep their failing health in check. At least, that was what it was intended for. What it actually ended up being was a home for the three now-immobile hogs, with quicker access to horrific food than ever before.


Yui groggily awoke after her last food coma, still feeling the chunky grease running down her massively fattened face. Her breasts had become so unreasonably overgrown that they hung off the sides of her double wide bed. She was pinned in place by her own obesity, but she couldn't bring herself to care. Her heart ached, palpitating from the twenty or so Cardiac Killers she ate for third lunch.
"You girlsh... *Uuuuuuoooorp-*, shtill h-hanging in there?"


Beside her was a humongous noise, loud enough to startle anyone, but she had quickly grown used to it. It was just Yuzuko's morbidly overswollen belly gurgling.
*OOOOOUUURRRRRRBLLBLBLLBLLLllbllbll...-*
Her stomach was permanently red and stretched, packed to the point the couldn't have been any room left inside. It rested on top of her like a gigantic, jiggly boulder. She had so many rolls they were difficult to count, and she spent all day cradling her poor congested chest. The school nurses told her that her cholesterol levels were so high, it was impressive that she was still conscious.
"I-I... I'm, huff, o-okay... o-ouch... what about you, *UUUUOOORP-*, Yukari?"


Yukari's upper half was morbidly obese, but her bottom half was a gargantuan blob of fat. There was so much cellulite and so many rolls, it was difficult to tell which parts were what. Her hips had grown so unnaturally wide that she needed a full double-sized bed for each obscene cheek. 


The three were now so slobby that they were head-to-toe in food, sauces, and grease. They spent more time belching and moaning than they did talking. Every breath was so loud and laborious that it winded them. Every bite they took of the horrific school food pushed them closer and closer to the rapidly approaching edge. That didn't scare them. In fact, it didn't even make them slow down. 


"Hello again, little piglets! I brought you more yummies!"


The school nurse wheeled in two extra large carts full of heart-wrenching fast food. As soon as the three saw it, they all groaned out in unison. 


Yui: "S-sho full..."
Yuzuko: "If I eat another bite, I might bust..."
Yukari: "*UUOOOOOooooorrrppp....-*"


The nurse looked at them coyly.
"Aw, no one's hungry? I guess I'll just put all this delicious food back..."


The three girls wailed out in unison:
"NO!"

The girls were having a bit of difficulty. Heart trouble wasn't exactly uncommon for them, but this was something else. There must have been something in those Quadruple Piggy Popper Pork Sandwhiches. They were each as big around as a tire, piled high with unbelivably fatty pork. The sauce was condensed lard, and there were huge chunks of raw cholesterol. Each girl had eaten about ten of them.
 
"Y-Yui- huff, I-I don't feel sh-sho good..."
Yuzuko was clutching her chest with her fat-ridden fingers, too pudgy to grab much. Underneath, her chest was throbbing. It felt like it was going to cave in.
 
Yui didn't respond, she was too busy catching her breath. She had eaten so much, so fast, that it seems to have somewhat squished her lungs. Every wheezing breath was hard on its own. Especially with unholy amounts of breast fat crushing her chest.
 
Yukari was still sloppily finishing up her last one. Remains of the previous nine were strewn about her thigh fat, falling into rolls and cellulite crevices. Her eating was slow, her arms were too fat to move quickly. Eventually she finished off every last bite, then leaned back into her super-squishy ass fat and let off some pressure.
*UUUUUUUUUUUUUUUOOORRRPPPPPppp-*
 
The three girls were hardly conscious. One wrong move would send them right over the edge. It was only now that they were questioning their dietary decisions over the past year. But it all tasted so good... how could they say no?
 
"Bon Appetite, piglets! I've got a surprise for you!"
 
"N-no, Mrsh. Nursh, I think we need medical attensh-"
Before she could finish, Yuzuko felt a tube pop into her mouth. Panicking, she looked over at the other girls. The nurse was gingerly placing two more tubes into their mouths as well. She traced the path back with her eyes to find they were connected to a gigantic barrel, labeled "USED FRYER OIL - DO NOT INGEST".
 
Immediately, a gigantic burst of unbearably salty and oily liquid filled up their ballooning cheeks. 
*Gulp, gulp, gulp, gulp, gulp, gulp...*
They couldn't do anything to stop it. Their stomachs expanded to make room for the disgusting liquid. After five minutes of agony, they felt themselves go light headed. The grease was entering their bloodstream, clogging their arteries. They saw stars, the room spun, their faces went pale. It was all too much, too fast. They had taken on way more than they could handle. Their horrifically unhealthy diets were now putting them to a grisly end. Hearts began slowing down, unable to pump their fatty blood through the impossibly narrow spaces in their veins, blocked by lard. "Heart attack" was an understatement, this was much, much worse. Unable to get free, the greasy blood backed up in their hearts, making them bulge and swell. The girls eyes opened wide, feeling something their chest expand, and expand, and expand... Until finally, a catastrophic explosion. 
In unison, the three girls' eyes rolled back in their heads at the sensation of the massive bursting inside their chests. This was exactly what they had been waiting for. Immediately, massive bursts of cum squirted out of their grease soaked panties onto the bed. They moaned and creamed with each other until their very last moments.
 
"Now then," the nurse spoke to herself. "That took quite a while. I wonder if we can find even unhealthier food to serve here..."
