“Bye guys! I'll miss you heaps!" waved Denise as she hugged her family goodbye. Her flight was about to leave.
"Oh, my baby girl's all grown up!" wailed her mother, pulling her into a tight hug.
"Mum, c'mon! I'll be fine." giggled Denise.
"See ya, sis!" perked Jackie, giving her sister a hug,
"Bring me back something."
Denise winked at her before swinging her bag over her shoulder and walking down the tunnel.
The whole flight there Denise couldn't stop thinking. Had she put on weight? Denise hated the thought of fatness, always exercising to keep herself in shape. However, since school's break-up, she had filled out a little as most kids do. Denise had been a little chubby when she was a little girl, her sister often taunted her about it. She came out of the chubby cocoon through puberty, developing a beautiful body. She was a little bottom heavy; her hips had always been somewhat wider than the rest of her body.
Denise's weight problem as a child left her with a serious denial problem. Throughout her teenage years, her weight had gone up and down, and although at no stage was she fat, she still became very defensive when someone brought up her size. She managed to push her body issues to the back of her mind, often ignoring them altogether. But as she sat in her plane seat silently, she couldn't stop staring at her thighs. They were squashed together in the seat, and Denise's slightly rounded bum was uncomfortably restricted by her tiny seat. It was going to be a long flight.
When Denise arrived to her hotel room on the other side of the world, the first thing she did was hurl her jet-lagged body onto her cream coloured bed.
"Uhhhh…" she moaned, her eyes felt so heavy. Slowly she drifted to sleep.
Over the next few weeks, Denise hadn't stopped. She had been so busy studying; she barely had time for anything else. The lack of physical activity was taking its toll on her body, as she began to expand even more. Now Denise was a smart girl, but one thing she couldn't do was cook for herself. As a result, she found herself ordering take away food every night.
Denise's weight gain was centered around her inflating bum and thighs. Her fattening pair of thighs and butt cheeks was joined by her now soft tummy. Her belly began to bulge over her pants, which were becoming harder and harder to button up.
"I'm too tired…" she would say, "I'll just get Chinese food…"
She was getting fatter and fatter. And since she couldn't buy new clothes, she was restricted to her now too small clothes she had packed. The other girls at her fashion class had noticed her gain, but never brought it up, which left Denise oblivious.
She woke up on the day of her trip home with a big headache. Her sleep had been rough.
"Crap! My flight leaves in an hour!" Denise suddenly noticed the clock.
She stumbled out of bed and stuffed her body into her shorts. She couldn’t help noticing how tight they were, constricting her plump thighs.
”Huh? Why are these so tight?" she thought, struggling to stuff her bloated, soft buns into them. Her perky, round buns were proving troublesome, her butt had gotten so big that her pants now couldn't cover all her rear, leaving her massive ass crack exposed. Try as she might, Denise couldn't button them. Her tubby gut stood between the flaps, which were so far apart Denise could only just make them touch. After a struggle, they were closed, but her breathing was laboured by the tightness of her shorts. Her waist was binded tightly, causing red marks to encircle her soft middle.
"Hmm… Ah well…" she said, realising she had to get a move on. She packed her bags and darted off.
Denise had gotten so plump that she found it hard to run, her out of shape body bouncing and wobbling as she did so.
"I'm not fat" she mumbled under her breath. ********
Denise walked up the front steps of her house. She was a little shocked her parents hadn't come to the airport to pick her up, but shrugged it off; she was too excited to see them. She knocked on the door, wondering if they would notice her weight gain. Even though she continued to tell herself she hadn't gained weight.
"Coming!" came a voice. It was Jackie.
Denise heard the fumbling of keys before the door opened. Both their eyes bulged. Jackie had put on weight too. The pair stood stunned for a second, shocked at each other's fatness.
"Hey sis!" Denise broke the silence.
"Denise!" the pair hugged awkwardly. Their massive breasts restricted them from hugging too close. Jackie looked a little doughy all over. Her tanned brown tummy poked out from beneath her over tight shirt, which was packed with Jackie's heaving boobs.
"Come on then, mum and dad are out the back! We missed you heaps!" said Jackie, who started for the back door. Denise followed her lead.
"Yeah, I missed you guys too." replied Denise, distracted by her little sister's exposed bum crack.
She noticed the tan line of where her pants used to sit, but now Jackie's white butt was pouring out over the top of her track pants. The two girls entered the backyard where their parents sat.
"Look who's home!" cried Jackie, smiling.
Denise noticed her parents give her a strange look, obviously noticing their daughter's weight gain, before exploding in happy greetings.
"Oh my baby girl!" cried her mother again, she was such a typical mum, thought Denise.
Her mum was able to slowly adjust to Jackie getting fat, since she saw it happen gradually. She never expected her sophisticated older daughter to blow up like she had; she thought Denise was past her chubby years. Not that her mum minded, after all, she was a little heavy and was at Denise's age too. She would have to get used to having two overweight daughters.
*******
Jackie and Denise had always been competitive. Now that both of them were fat and in denial, both planned to confront the other. They were typical teenage girls, hating the thought of being overweight and always worried about the size of their bums. Denise cringed at the thought of having a big bum, and now that she had one, it had pushed her into complete denial. Jackie was a little more lenient with her weight gain, she wasn't in denial but was a little naive of it. The two shared a bedroom, and spent the rest of the afternoon catching up. Denise tipped her suitcase contents onto her bed while Jackie lay on her bed holding a teddy.
"So what happened on your trip?" suggested Jackie.
"Not a lot, I was so busy."
"Doing what?" nagged Jackie.
"Oh just work and stuff." said Denise.
Jackie was searching for a way to bring up her big sister's weight. She spotted the red marks on Denise's oozing waist where her pants dug into her.
"Those pants look pretty tight." teased Jackie.
Denise was quick to respond, "So do yours. Are you saying I'm fat?"
"Are you saying you're not?" sniggered Jackie.
Denise's mouth hit the floor, "I am not fat!" She defensively grabbed her pudgy tummy. "You've gotten a little porky."
"Nu uh!" whined Jackie.
"Don't try and tell me I'm fat just to hide your own flabbiness, tubby girl!"
Jackie fumed, "But you ARE fat! What did you do all holidays? Eat?!"
"You're fat! I have not gotten bigger!" said Denise proudly. Jackie could see she was sucking her gut in.
"Whatever, fatty bum!" said Jackie before leaving the room, tossing her blondy brown hair behind her.
******
Over the next few weeks the pair continued to gain weight. Denise's mother thought that her eldest daughter would slim down after adjusting back to her usual eating patterns. Thus was not the case. Denise got plumper and plumper, especially in the bum. Her midriff was wide, pudgy and wobbly. Her thighs and hips had porked up with her buttocks leading the way.
Her fat buns got wider, rounder, fatter and softer as Denise ate more and more. Jackie naively stuffed her chubby face and was getting much wider in her boobs, tummy and hips. Both remained in denial of their weight, especially Denise.
One afternoon, Denise was helping herself to a piece of chocolate cake her mum had made. Jackie sat at the kitchen table watching her puffy sister cut herself a generous slice. She waddled over and sat down with her, licking the icing off her fingers as she did. Her expanding bottom hit the chair with a plonk, sending ripples through her soft belly rolls. Her white button down shirt stretched tight across her plump breasts and tummy. Denise daintily began to eat her cake, spreading chocolate all over her big lips.
"Good cake?" asked Jackie.
"Mmmmm." muffled Denise.
"It's going straight to that big fat bum of yours." laughed Jackie.
"Shut up, tubby." replied Denise.
Jackie was unaffected; "You must be like a million kilos by now, eh?"
Denise's face went bright red. She looked down to see her enormous hips spreading over the edges of her chair. Her gut sat in three rolls in her lap, and behind her, her perky butt was exposed at the top. The girl's mother entered.
"Mum, Jackie said I had a fat bum." said Denise behind a mouthful of cake.
Their mother said nothing.
"She said I was tubby!" added Jackie.
"Why don't you girls go for a walk to clear your heads? Maybe even a jog." their mum replied sounding a little more forceful.
"I guess we can," said Jackie, "It'll give Denise a chance to shed some fat off that ass."
"My bum isn't big!" The two girls argued out the front door.
***
"Why did Mum want us to walk so bad?" asked Denise.
"Because you, my lovely sister, are too fat!" laughed Jackie.
"I am not fat! Besides, you're a little chubby…" protested Denise defensively.
"Oh sure, is that why you're wearing jeans jogging… that button looks like it's hanging on for dear life, mind you!"
Denise's heart skipped a beat. Her jeans were the only pants that still fit, and they too were very uncomfortable.
"Shut up! You're wearing track pants!"
Jackie ignored her, "I bet those jeans are the only pants you can fit around your big fat bum!"
"Shut up!" Denise was getting quite angry, her face blushed red as she fiddled with the button to relieve some of the stress. The pants were cutting uncomfortably into her squishy hips, a red mark encircling her widening waist. Denise had gotten so fat. Her rounded tummy bulged out in front of her, with her inflating breasts joining it. Her love handles were more prominent due to her tight jeans, which were straining hard to contain her plump hips and chunky thighs. But it was here bum where most of her excess flab had gone. Her bloated bottom stuck out so far behind her, bouncing and wobbling as she walked. Denise had remained very much in denial about her weight gain. She got butterflies whenever she had a lapse of insecurity. The thought of being fat made her feel very nervous. Whenever it had been brought up, she had become very defensive, refusing to admit she had packed on the pounds. Despite realising deep down she had put on a little blubber, she was oblivious to the fact she had gotten well and truly overweight.
Jackie's middle had filled up too, a considerable belly roll bulging over the waistband of her trackies. Her boobs strained at her tight scarlet t-shirt, and behind, her butt crack was exposed. Jackie's rump had gotten more wide than fat, accumulating a lot of flesh on her hips. In any account, both had gotten very overweight.
They began to waddle down the road. While they had intended to jog, they were both so out of shape that it was very difficult. They followed a winding downhill road through their quiet, forested town, before reaching their local park. This had been a good hang out for the girls. Playing in the playground set, before kicking a football around once they were a little older. That was of course before they had gotten plump. If they were to try and kick a ball now, they would probably lose balance.
"Ahh, I love this park." said Jackie, sitting on a bench.
Denise stood with her hands on her hips, panting.
"You tired all ready fatso?"
"Shut up, I have heaps of energy left. Beside, your fat, you should be more puffed out then me." Huffed Denise.
"Do you see me panting?" asked Jackie, "Besides, you're fatter, you're in denial."
"You're probably hiding your panting… and I am not in denial because I am not fat!" contradicted Denise.
Jackie was getting a little testy. Her big sister refused to believe she was a porker. How could she prove it? They had already gone walking, and Denise had survived that. Jackie sat in thought.
"Remember when we used to play follow the leader?" said Denise, staring longingly at the play equipment.
An idea struck in Jackie's head. Seeing all those obstacles, there must be something that would prove Denise's fatness.
"Yeah, let's play for old time's sake!" said Jackie.
The sisters walked over to the playground and sat on a little platform.
"Ok, I'll be the leader first." said Jackie, "You gotta keep up with me."
"Easy." puffed Denise.
Jackie smiled, "Let's make it interesting."
"I'm listening."
"Well, if you CAN'T complete any obstacles I set, you gotta admit you've packed on the pounds."
Denise scowled at her little sister.
"You're on." agreed Denise. This was a chance to get her sister off her back.
*******
Jackie mapped out a path in her mind around the set. She was confident there must be one challenge Denise couldn't complete because of her size.
“Challenge number one.” said Jackie, “The flying fox.” They strolled over to the little flying fox, which was completely horizontal and about five metres between the two platforms on either side. It stood just out of the girl’s reach, as Jackie jumped up and grabbed the handle for the flying fox. Her movements were awkward and restricted by her excess flab. Her arms holding onto the bar meant her shirt slid up. Denise watched as her sister's chubby body clumsily flew across the flying fox. Jackie stepped off onto the other side.
"Hmph…" she gasped, tugging her shirt back down. Her face was red from exertion.
"Your turn." Jackie said as she pushed the handle back across its track to the other side, where Denise stood biting her lip.
"If she can do it, I can." concluded Denise, before trying to jump up and grab the handle. She missed and hit the platform with a thud. Shockwaves were sent through her tubby belly.
"C'mon fatso!" taunted Jackie. Her sister's taunts fuelled Denise, as she once again leapt up and this time grabbed the handle.
"Mmph!" she struggled, as she pushed herself off the platform. The flying fox left slowly, before stopping in the middle, leaving Denise hanging there. She kicked her fat legs, trying to get some momentum. Her shirt rode up to reveal practically all her tummy. Her deep belly button and pale skin was exposed as her little sister waddled over to her.
"You can't give up now, tubby guts!" she giggled, pinching Denise's soft flesh. Denise wriggled and squirmed to fend off her irritating sister, and finally managed to work her to the other side. Denise was panting already. She wasn't used to so much physical movement.
"Alright, you passed this test. Follow me." Continued her little sister. Denise followed Jackie around to the foot of a climbing pole.
"Challenge two." said Jackie, "Is to climb this pole." Jackie wrapped her pudgy body around the pole and began to climb. Denise noted her sister's butt crack becoming exposed as her over tight grey track pants began to slide down. Denise was surprised at Jackie's climbing ability, as she reached the top with no fuss.
"There's no way she'll be able to pull herself up! Haha!" laughed Jackie to herself. Her big sister's girth had become overwhelming and it showed as she tried to climb the pole.
Unfortunately for Denise, her meaty arms meant she had little to no upper body strength. This was something Jackie had taken note of. However, Denise defied her critic by twisting her legs up onto the high platform pulling her fat body up. Denise too, was determined to prove that her sister had gotten porky.
"Am I wearing you out?" smirked Denise cheekily to her younger sister.
"Ha! No chance." panted Jackie, who hadn't done much exercise recently either, "Your bum crack is showing fat girl!"
Denise's face blushed bright red as she tugged her tight jeans up. She was ignoring the fact that her massive derriere felt unbearably uncomfortable in those jeans.
Jackie was getting frustrated. How could she prove her big sister was becoming a blimp? From the top platform, the only way down was the slide. Not very challenging, thought Jackie. Unless… Jackie examined the slide with the width of her sister's hips.
"Yes… there's no way her hips are small enough for that slide." thought Jackie.
"Ok." she said out loud, "Next challenge, the slide!" Denise gave her a sceptical look.
Jackie underestimated just how rounded her own hips and butt had become. She squirmed into a sitting position, but found she couldn't get any momentum to push off. Denise just watched her little sister slide down slowly and jerkily; she too had noticed her sister's hips were a little too big. Jackie was looking a little beaten when she stood at the foot of the slide.
"This'll be it. This'll prove it." thought a determined Jackie. Denise, still obliviously to her sister's motives, eventually managed to get herself into a sitting position.
"Oh crap… my hips aren't going to fit." Thought Denise, "No! If Jackie fit, so will I!"
Denise's inflated hips rubbed against the sides of the slide, as she wriggled her well-filled out butt into position. Her soft belly sat in three rolls before her, jiggling every time she tried to push herself forward. Slowly but surely, Denise slid down the slide. Jackie winced as her sister had managed to fit. Hoping her enormous bum would get stuck somewhere down that slide, Jackie's goal was soon crushed as her tubby sister reached the bottom.
"Oof… what's next?" asked Denise.
Jackie was fuming on the inside. She's so fat! Why can't she see that?! How can I prove it? Suddenly something caught her eye. Under the slide was a large cubbyhouse. This cubbyhouse was in the shape of a ship, full of portholes and little wooden steering wheels. Denise and Jackie had played in there all the time when they were little, pretending they were pirates.
"That's it!" thought Jackie, "No way she'll be able to squeeze through those portholes."
Denise stood behind her sister, arms folded to cover her tummy. This action had become a subconscious way to reduce the size of her paunch.
"Denise, you're fat! Why won't you admit it?" shot her sister suddenly.
"No I'm not!" grumbled the older sister, "What is this obsession you have? I think you're just jealous because you've put on weight yourself!" Denise was sucking in her tummy defensively, her chubby face scowling.
"Yeah? Well he's my final challenge. Fit through this porthole, and I'll stop calling you fat." Huffed Jackie. Denise eyed the porthole doubtfully. She didn't think either of them would be able to fit through, and not because they were fat, simply because her sister had picked one of the smaller portholes.
"I dunno, I mean we haven't been in there since we were little…" Jackie giggled, "You're just scared you won’t fit through and it'll prove me right!"
Denise frowned, "Fine, you can, but I'm not going to."
"Then you'll lose, c'mon, I'll prove you can fit." pestered Jackie, determined to make her point.
Jackie lay down on her stomach and began to shimmy her way through. Jackie too, had fattened up since Denise had gotten back from her holiday. Denise heard Jackie's grunts as she struggled to squeeze through the tight hole.
"Uhh..." mumbled Jackie, twisting to pop her little potbelly through. She had to fit through she thought. At least if she found it difficult, surely Denise would have more trouble. She had been so preoccupied with her older sister's size that she forgot to take her own fatness into account. Jackie found the squeeze much more difficult than expected. After eventually shoving her tubby belly through the hole, Jackie pushed again, but jerked suddenly and didn't move anywhere. Her well-rounded bum was caught on the outside of the porthole and Jackie couldn't squeeze it through. Denise noticed her sister's struggles and smirked.
"Denise! I'm stuck! Help!" complained Jackie, kicking her softened legs.
Denise rolled her eyes before shoving her hands into her little sister's widened rump. The combination of Jackie's twisting and Denise's pushing was enough to squash her through. Denise peered into the hole to see her little sister sprawled on the dead leaves on the ground. The shove had forced her pants to slide down, and Jackie's ass crack was generously exposed. She stood up, plucking the leaves out of her blondy-brown hair and pulling her pants up.
"Showed you!" laughed Jackie, a little shaken by the whole incident.
"See! I'm skinnier than you! You're a fat pig!"
Now it was Denise's turn. She bit her lip doubtfully as Jackie continued to hurl abuse at her. Could she fit? Of course! Jackie was fatter than her anyway she thought. And Jackie's fatty taunts only fuelled her desire to prove her little sister wrong. “I mean if she fit through after putting on all that weight, I'll fit through easily!” thought Denise; after all, she was under the idea that she was the same size, if not skinnier than her sister.
She decided to take a different approach. She lay on her stomach and tucked her feet through the hole first.
"Maybe I'll fit through easier if I go through feet first." thought Denise. She squished her thighs though before her bottom of her well-filled bum pressed against the hole with a quiet thump noise. She twisted, trying to squeeze her fat ass through but to no avail, she couldn't even squeeze a little bit of cheek through. She pulled her legs back through to start again.
"Well that just proved your bum's fat!" giggled Jackie.
"Shut up! It'll fit through on a different angle...." protested Denise.
Denise struggled to lie on her tummy, her massive body restricting her movements. She was extra careful not to blow her pants open, as the button was hanging on for dear life. She lay on her fleshy stomach and poked her arms and head through. After twisting her shoulders and arms in, she began to push on the sides of the door. She strained, but didn't seem to be moving anywhere; her rounded breasts were too big.
"Haha! Look at you, you can't even get halfway in!" laughed Jackie, hoping and wishing her sister wouldn’t fit through.
Denise was quick to respond, "Yeah, at least I have bigger boobs than you!"
This hushed her sister and Denise's huge chest popped through after some wriggling. That should be the hardest part, thought Denise. She continued to squirm, stuffing her round belly through. She felt uncomfortable, the porthole hugged her very tightly, and it obviously wasn't as easy as when she was a young girl. Jackie swore to herself when she noticed Denise had stuffed all of her plumped torso through the hole.
She couldn't help staring at all the fat stuffed around the door, Denise's plump waist oozing and bulging around the plugged doorway.
Unfortunately for Denise, the challenge would hit a snag with the next shove. Denise pushed forcefully on the sides of the hole, but felt some resistance in her hips. She pushed again but her bum had become hopelessly wedged into the hole. Denise began to panic and squirm desperately. Her inflated bottom was simply too fat to squeeze through the porthole.
"Stuck?"
"No!" shouted Denise, refusing to believe she couldn't fit through. There was no way she couldn't fit! Her sister managed, and she was fat! Denise fumbled for excuses in her head as she continued to wriggle her plump bum cheeks in a vain attempt to squish through. On the other side of the hole, Denise's bottom was quivering from side to side; the excess flesh she had accumulated there was now hindering her attempts to fit. Her tight jeans caused her massive butt cheeks to spread apart, with the materials of her jeans stretched tightly across the pair. They wobbled uncontrollably to Denise's embarrassment.
"You're stuck aren't you!" giggled Jackie, "Teehee! You're jiggly butt is too big!"
"You're such a pest!" squealed Denise, flailing her arms out trying to slap her sister. Her long, dark brown hair was dishevelled upon her face. Jackie continued to torment her.
"Denise is a fatty! Denise is a fatty!" she laughed,
"I have an older sister, her name is Denise, SHE'S FAT!"
Jackie continued to jump around, her blonde hair bouncing up and down with her big boobs and bloated tummy. Denise felt her face go red hot with anger and embarrassment. She kicked, trying to shove her massive bum through, but the circumference of her porky hips was too round. Denise was stuck fast, whether she was going to admit it or not. After a few minutes, Jackie calmed down but Denise was still trying to push herself through. She was too stubborn to admit she'd gained weight, let alone be fatter than her sister. If Jackie could fit through here being her size, so could she!
"Alright Jackie... " submitted Denise, "I'm stuck. But this soooo doesn't mean I'm fat! You needed help too, remember, so that means you're still the bigger one of us."
"I don’t think I'll help you at all." teased Jackie.
"Nononono!" kicked Denise.
"Say please..." giggled Jackie, knowing she had power.
Denise sighed, "...Please... "
"Please what? Teehee!"
"Grr!"
"Okok, I'm sorry," said Jackie, before grabbing her chubby sister's arms.
The two girls pulled tenaciously, trying to force Denise's bloated rear through the hole. She moved slightly, the top of her deep ass crack peeping through. Denise twisted her mammoth hips, which only resulted in her tight jeans being pushed down slightly. They tugged and tugged, but Denise's butt was too fat.
"Woah, I knew your bottom was huge, but not this huge!" giggled Jackie. Pushing Denise's bum cheeks through was like trying to fit two large beach balls through a hoola-hoop. Impossible. Denise was feeling so embarrassed, this must be a girl's worst nightmare. Her bum was too fat to squeeze through. Jackie's pulling had caused Denise's clothes to become more uncomfortable. Her shirt had rode up from the tugging, exposing Denise's soft, full tummy. Behind, her pants had slid down to reveal more of her pale bums crack. Jackie made one more tug before giving up.
"Denise, you're going to have to admit you've gained weight, your bottom won't fit."
"It CAN fit!" protested Denise in denial, "I have not gained weight, you have!"
"Oh crap!" she hissed.
She pushed hard, but large rolls of dough blocked the porthole.
"Uhh... hmp... Ah!" she squealed as she rolled off the top and onto the outside with a plod. She proceeded round to where Denise was wedged. Her overweight sister was kicking her chubby legs, her plump thighs quivering with each movement.
"Teehee look at your fat butt!" teased Jackie, before giving her rump heavy sister a pinch on the bum. Denise squealed like a little piglet before continuing to kick in an attempt to fend off her pestering sister.
"It's like jelly!" continued Jackie, smacking and poking her fat sister's enormous ass.
"Jackie, cut it out!" fumed Denise, "Please help me!"
"Okok. Stop kicking and I'll pull you out." Said Jackie.
Denise liked Jackie's confidence. Her younger sister grabbed hold of Denise at the bottom of her round thighs and yanked as hard as she could.
"Oof!" grunted Denise, but the forceful pull had only resulted in massive belly rolls continuing to block her escape.
"Suck it in, fatso!" giggled Jackie, tugging again.
Denise inhaled as deeply as she possibly could. Her tummy shrank a little as Jackie pulled again, but to no avail. Denise's love handles couldn't be sucked in.
Her chubby tummy wouldn't fit back out.
"This isn't fair! I fit it through the first time!" moaned Denise.
"It's all the angle, sis." replied her realistic sister.
Jackie didn't see what else she could do.
"Ok Denise, I'll try and push you in."
"Ok." sniffled Denise.
The two girls braced themselves. Denise placed her pudgy hands onto the wall next to her enormous waist, ready to push. Jackie examined her sister's butt before sinking her fingers into the flesh of her expanded bottom. Jackie found it hard to get a good grip, all she could hang onto was a large handful of tender butt flab.
"Ready?" asked Jackie, eventually finding her bearings.
"Yep." replied Denise.
"One... Two... THREE!"
The girls shoved forcefully, Denise's rump spread wide around the plugged hole, but no forward movement.
Jackie's shoves separated each spherical cheek, however Denise's ass was too big and round.
"Denise, I hate to say it, but I'm stumped. I got no idea how you're going to get out." said Jackie, wheezing from exertion. Her deep breaths caused her shirt to spread tight across her colossal boobs and tummy. Denise too was having trouble breathing from the lack of exercise. Her face was beet red and in tears. She realised now just how much of a predicament she was in. There was no sound for a while, and Denise began to fear Jackie had walked off. Her fear was relieved when Jackie stumbled back over the wall of the ship and she landed back inside. Denise was crying softly.
"Sis, don't cry!" moped Jackie, feeling guilty for what she had done.
"It's not fair... I didn't mean to get so fat!" cried Denise, "My bum just got bigger and bigger!"
This made Jackie feel a little better. She had done it. Denise had admitted she was fat.
"I'll admit then that I have gotten chubby too." Said Jackie in an attempt to comfort her sister.
"I mean, c'mon! You're fatter than me, Jackie! How did you fit through?" moped Denise.
Jackie's mood changed suddenly. Denise still thought Jackie was the fattest.
"Denise... I fit through, you're the fat one."
Denise looked up, angry, "No, you're too fat!"
Jackie leapt to her feet, "I'm too fat?! You're the one who can't fit through that hole! You're the fattest sister ever!"
"Oh yeah! Well prove it. Squeeze through this porthole here." Denise pointed to a smaller porthole next to the one blocked with her body. Jackie pouted doubtfully. She had struggled enough getting through the first hole, and this one was possibly a bit smaller.
"Gee, I don't know, sis...."
"Ha! You're a scared because you know that you're the fatter sister." Denise retorted defensively.
"Am not!" whined Jackie, grabbing her soft tummy.
"Prove it!"
"Fine! It'll be a piece of cake for someone as thin as me!"
Jackie proceeded to squash through the smaller hole. After squeezing her large bust through the small hole she was troubled at her tubby belly.
From Denise's view, all she could see was her little sister's blubbery lower body kicking and pushing.
"Ung!" moaned Jackie, having trouble squashing through.
Jackie had gotten her upper half through the porthole but her hips and butt wouldn’t squeeze through.
Damn it! I knew this was a bad idea! Jackie swore to herself, she was stuck too.
"I guess it's not a piece of cake after all, eh Jackie?"
"Shut up, fat girl!"
"I'd say it was a piece of cake that got you stuck there, greedy guts!"
Both the fat siblings were stuck in their own porthole.
Denise was fuming, struggling to admit she had gotten so rounded.
"Ugh! This is your fault!" screamed Denise, kicking her legs in a tantrum.
"My fault?! You're the one that got so fat!" returned Jackie. "You and your stupid obstacle course!"
"Don't yell at me!" demanded Jackie, smacking her big sister on the butt. Denise's right bum cheek fluttered, the slap sending a ripple of fat through her inflated rear.
Denise gasped, her mouth almost hitting the floor.
"Don't smack me!" snapped Denise, giving her sister a whack on the rump.
"Don't smack ME!"
"You hit me first!"
"You got stuck first!"
"You got fatter first!"
"No you!"
"No you!"
The girls broke out in a serious tantrum, the pair arguing like little kids. Both girls went silent when they heard a car pull up beside the park. Jackie could see it. Her eyes widened. It was their mother.
"Jackie? Who is it?" asked Denise, who couldn't because she was facing the other way.
"There you girls are!"
Denise's heart skipped a beat. The girl's stern mother walked over to where her overweight daughters were wedged.
"Mum! Jackie made me get stuck in here!" whined Denise, kicking her wide legs.
"She hit me on the bum!" complained Jackie.
"I don't care!" bellowed their mother in a tone, which silenced them both.
"You two have gotten seriously chubby. You tell me you're going jogging and I find you both too fat to squeeze through these holes?!"
"I'm not fat, mum! This thing is designed for little kids!" Denise fumbled for excuses.
"That's enough Denise, you're going on a serious diet, missy."
"But mum!"
Jackie started laughing before her mother gave her a stern look. Jackie looked away quick smart.
"You too, young lady." she turned to Jackie.
Jackie's jaw dropped.
"Me?! But she's the fat one!"
"You both have gotten fat!" replied their mother, “It’s diets for the both of you, end of story."
Denise and Jackie couldn't believe the situation. The pair of sisters had each packed on weight, and now were both incredibly tubby. Denise especially, as her bum had swollen up, now looking like an out of shape, inflated peach. Denise's denial now meant she had her big bum and thighs stuffed tight into this hole.
Jackie's small potbelly, wider hips and bum still boasted considerable size, and too had gotten stuck. The two competitive sisters had become so obsessed with each other’s weight that they had not realised the full extent of their own gains, and paid the price by finding themselves in such an incredibly embarrassing situation!
