Pop and Lock

The whispers started early that day. “Ugh, it’s disgusting, she’s such a whore.” Sarah mumbled. “I know” Michelle replied “those fucking basketballs she calls breasts are obviously plastic. And could her shirt be any tighter? I feel like we’re only seconds away from a free show, and buttons flying everywhere.”

As Katie gave a presentation to her global economy class, she was oblivious to comments from onlookers.

She stood 5 foot 5, with tan skin, long brown hair (which reached her lower back), an athletic body and an absolutely perfect face, with beautiful big brown eyes, and plump pouty red lips. She had D cup breasts, which was unusual for a girl on the dance team, and most people assumed they were fake, and rightly so. As she pointed to her power point presentation, her white cotton button down shirt tightly hugged her globular breasts; her overly abundant and deep tan cleavage was prominently displayed through the gaps between the straining buttons. It looked as though the top button was begging to burst free, but alas, it did not. A large red vinyl belt was wrapped around her waist, atop very tight black suit pants, which complimented her pronounced rear very well.

While guys loved Katie’s “upstairs”, they really loved her “downstairs”. It was probably because she was a dancer, and knew how to wear tight pants which looked as though they were painted on. Her butt was the size of two firm cantaloupes, and was shaped in a perfect bubble. Guys fawned over her for it, and other girls hated her for it.

Personality wise, Katie was much less perfect however. She clearly understood how attractive she was, and consistently used it to get her way. She cheated on boyfriends, used guys to do work for her, and treated all girls as if they were below her. She was like a mini celebrity within the community of her college. All the guys wanted to do her, the girls wanted to be her, and everyone wanted to talk about her.

After copying Sarah’s answers on their latest econ test, and earning them both failing grades after being caught, Sarah had developed a true hatred for Katie. She hated everything about her, and she had devised a plan to exact her revenge, and take Katie down from her high society status.

As Katie proceeded with her presentation, Sarah decided it was the perfect opportunity to give her plan a little test run. Staring at Katie, she snapped her fingers.

Katie, who was facing the wall where the presentation was being projected, momentarily went wide eyed. Her mouth went agape and her hands shot to her stomach as she felt a sharp growing pressure. And then within moments, the pressure was gone. Katie let out a sigh of relief, composed herself and continued on with her presentation.

But that’s when it happened, with her back to the students, Katie’s pants started pushing out toward the audience, each cheek ballooning and becoming rounder by the second, stretching out the seat of her slacks and slowly reaching the size of two over pumped volleyballs. Katie continued on, unaware of the growth, her rear swaying from side to side as it swelled and as she pointed to the board. The seat of her pants, ready to burst down the center began to give way, a single stitch ripped, and Sarah stopped the inflation.

Katie’s rear now protruded a full 8 inches behind her and each side could even be seen from the front (each butt cheek, not her hips). It was large enough for a soda can to rest on top of, and looked as though if it were slapped, or any sudden movement, would force it to burst free from it’s paper thin confines. It continued to bob up and down, as Katie moved around enthusiastically. She didn’t even notice what had happened, and only a few classmates could tell her rear was bigger than usual (with nobody besides Sarah actually seeing the growth in its brief glory).

“Wow,” a girl in the front of the class whispered to her friend, “Katie needs to lay off the sweets, her butt looks enormous!”

“Katie’s always had a fat ass, you’re just noticing now?” the friend responded.

“I know she’s always had a big ass, but look at it… it looks so much rounder and wider than usual, like it’s just sticking so far out” the girl insisted.

“Ha, you’re right,” the friend replied upon closer inspection, “it looks ready to pop free or something”

“I mean, how does she even sit down on that thing without ripping her pants wide open? Can she even fit in a chair?!” The other girl continued.

“She probably likes it so she can arch her back more and show the world those enormous fucking clown boobs.”

“Haha, yea, well if she keeps on with that sweet tooth her butt will be bigger than her implants in no time.”

“…Yea, it does look like her pants are going to split open any second.”

“That’d be funny.”

Their conversation came to an end as Katie’s presentation concluded with a round of clapping from the class (or at least from the guys anyway).

As the clock struck 3:30 the class ended and the students gathered their things as they prepared to head to their next class or activity for the day. Sarah peered over at Katie, she grinned as she looked at her comically large bottom, which was bouncing slightly with each step Katie took and was pleading to rip right through its black skin tight boundaries. Sarah snapped her fingers, and walked out.

Katie walked through the hall, garnering the usual stares from guys drooling over her, and an unusually high amount from girls. Some pointed and giggled upon sight of Katie’s gargantuan rear which looked ready to burst out of her clothes, but she didn’t even notice, completely lost in her own world on the way to practice for the dance team. She was the captain, and was very excited to go over a new routine she had choreographed the previous night.

Katie arrived at the locker room to find all her team mates already changing. Stripping down to their bra and panties, getting ready to put on their dance team uniforms: skin tight black spandex pants, a matching tight black top, and large white belt across the abdomen.

As Katie walked passed the other girls to her locker, some said hi, and some just gawked at the sight of her jumbo bubble butt.

“Holy shit Katie!” Kristen exclaimed, as she approached Katie.

“It’s time to lay off the Taco Bell! Your ass is huge!” she exclaimed as she grabbed it with both hands and gave it a firm squeeze. Her hands sinking in to the mountains of butt flesh.

Katie yelped and spun around to face Kristen.

“Hey! None of that today, I’m in no mood for it!” Katie replied. Katie always had a pretty big rear end, and was used to the comments, so she didn’t realize anything out of the norm.

“No, I’m serious.” Kristen retorted as she pointed to Katie’s rear, “Your ass is looking seriously extra fat today, like its massive, I’m surprised your pants haven’t exploded off of it!”

Some of the other girls giggled upon hearing this, none of them liked Katie, but only Kristen had the Gaul to confront her about anything.

“Shut up, Kristen!” Katie exclaimed, “How would you like to warm the bench for the rest of the semester?!”

That zipped shut Kristen’s mouth, and good.

Katie turned to her locker and began undressing, she unbuckled her belt, than unbuttoned her blouse and took off her shirt, proudly revealing her silicone bust, which seemed to be desperately trying to escape an entirely too small sports bra which left her tan grapefruit sized breasts crammed together (creating a grand canyon of cleavage) and spilling over the sides. She finally came to her pants.

She tried to undo the button, but she couldn’t – it was altogether too tight. As she struggled for what seemed like forever, she received a comment from the peanut gallery.

“If you’re having trouble Katie, just bend over, I doubt your pants will survive the pressure from the twin moons of fat you’re smuggling under there. I’m shocked they’re surviving right now”

Katie’s eyes darted to Kristen, giving her a look which essentially read “shut the fuck up, or I’ll end you.”

Finally she unfastened the button and began to pull down her pants. This also appeared to be no small task with her rotund rump’s newly inflated mass.

After hearing many stitches rip in the process and vigorous effort Katie finally forced her pants down, leaving her near naked enormous butt jiggling in the air. ‘Oh god, why was that so hard!? Maybe I do need to lose some weight…’ Katie thought to herself.

Upon seeing Katie’s panty clad butt, all the girls who looked over were shocked. It appeared as if her almost nude butt had swallowed up her light blue panties, creating an enormous wedgy and making it seem as though she was sporting a thong.

“Woaaaaa,” one of the girls whispered to another “how did she gain that much weight that fast!? Her ass is gigantic!!!!”

“I don’t know” another replied “but it’s pretty funny that it all went to her butt! Did you see how long it was jiggling when she pried her pants off? It had some kind of perpetual motion going on!”

“I can’t even believe she was able to get them off, it looked like she was going to need the jaws of life to get her fat butt free”

Kristen, barely overhearing the other girls saying this, took another gander of her own at Katie’s oversized rump. ‘What the hell!?’ she said to herself, doing a double take.

As Katie bent over with her tan bulbous butt in the air, she searched the inside of her locker for her uniform. Kristin watched as Katie’s rear began to expand, her thighs joined in, filling out ever so slowly getting bigger and rounder, and adding another 2 inches to her butt’s overall already enormous circumference and causing her already dire wedgy to become even deeper, slipping further up her butt. Her lower half was beginning to look drastically plump.

As she found her uniform, and stood up, the inflation stopped, and Katie hadn’t realized a thing. Her corpulent rump distended about a foot behind her at this point. Kristen decided to say nothing, none of the other girls noticed, and she figured Katie deserved it.

Katie, finally finding her uniform, slid on her black cotton top, which was a little too small, and really showed off her relatively gargantuan tits (which was her intention) seemingly suspending them in mid air. She then pulled up her pants, albeit with some difficulty, but not too much considering it was spandex. She then secured the large white belt around her petite waist and began to lead the team into the gymnasium. Her rear vigorously wobbling with each step she took.

“Congrats Katie!” Kristen said mockingly, “I never thought you’d be able to cram your colossal ass into such a small space without exploding out of it!”

Katie shot her another angered glare in response.

Once all the girls reached the gym floor, they all got into their respective positions, with Katie in front, and providing them all with an excellent view of her already monstrously plump and tight rear.

One of the girls turned on the music and they began their usual routine.

Almost instantly Katie felt the pressure she had felt earlier that day in class, but much stronger. ‘Ugh did I eat something bad?! Why I am feeling so bloated!?’ she thought to herself and once again, as fast the pressure came, it left.

And that’s when it started again; Katie’s butt began to inflate outwards growing bigger in all directions. Slowly at first though, you would have only realized it if you were staring at it. Each buttock pumped up to the size of a basketball, and all the girls began to take notice. Katie didn’t feel a thing however, and continued dancing, her butt bounced and jiggled as it swelled larger and rounder with each beat of the music. The girls started gasping, pointing and whispering amongst themselves.

“WHAT THE HELL!” one girl whispered, “What’s happening to Katie’s butt?!!”

“She’s getting fatter by the second!”

“Her ass is blowing up like a balloon!”

“I guess she should lay off the fast food afterall!”

“Her butt is so fat! It looks like it’s about to burst right through her spandex!!!”

Katie’s butt now appeared to be a little larger than two firm basketballs in black spandex, bouncing up and down wildly along with her, and still growing, pushing out the seat of her pants, and stretching the spandex thinner.

Then, the growth picked up pace, and each butt cheek inflated to the size of a small beach ball, extremely round, and continuing to defy any hint of gravity. Her butt got bigger and rounder and wider with each step she took. Katie, still unaware, came dangerously close to touching Kristen with her continuously expanding rump during the routine when Kristen screamed, “Get your huge ass the fuck away from me before I stick it with a pin and pop it!”

“What the fuck are you talking about!?” Katie said as she whipped around.

“Are you a fucking moron Katie?” Kristen replied “Look at your ass, it’s probably about to explode.”

Katie turned her head to get a view of her growing butt and instantly screamed, “Oh my god what the fuck is happening to me!!!!?!?????????? My ass is blowing up, someone help!” She felt her feet freeze in place unable to move.

Upon finishing that sentence, she immediately felt an enormous pressure directly within her rear, and her butt started growing even faster, quickly approaching the size of two enormously tight over pumped beach balls begging to burst. She could feel her skin widening and stretching, trying to adapt to her new backside. She felt as though any second she would literally explode. Her ass at this point distended about 2 and a half feet behind her, and was about 5 feet wide, and growing fast. It looked like an entire 30 rack of beer could safely rest upon it.

“Oh…OH… I feel like my butts about to bust wide open! Do something!” Katie screamed in utter panic. The girls crowded around her trying to figure out what was happening and began poking and prodding her swelling rump.

“Wow its so tight”

“It feels like a balloon”

“Is she filling with air??!”

“Stop touching me! Help me!? Someone DO SOMEHTNIG NOW” Katie demanded.

“Your butt is getting so fat! What did you eat Katie!??!” a girl asked.

“I didn’t eat anything you slut!” Katie screamed.

“You’re a bitch, or should I say, an ass,” Kristen replied, “you don’t deserve our help.”

Katie shrieked in anger. Her butt’s inflation was showing no signs of slowing, growing at an extremely rapid pace, and getting bigger and bigger with each passing second. Her taut black spandex pants began to make warning noises, a sign they couldn’t take any more of Katie’s huge ass, even starting to shine. As the spandex seemingly forced the swelling to slow down, each butt cheek began to now touch the floor even as she was standing.

“OH MY GOD!!! HEELLPP!” Katie screamed.

The girls, who continued to poke and slap and pinch her growing butt, couldn’t resist but make more unhelpful remarks.

“It looks like there’s no more room in the spandex!”

“Its so big and tight! Its touching the floor!!”

“I’ve never seen such a fat ass before! It looks like its about to pop!”

“It feels like it too!”

“I feel like I’m touching a basketball!”

“I wonder if it bounces like one…?” Kristen put in.

“Ughhhhhhhhhhh,” Katie moaned in pain feeling her skin stretching, “stop touching my ass and get help before I pop you fucking bitches!”

Hearing this, a big grin rolled across Kristen’s face, she walked behind Katie and placed a hand on each side of her inflating rump.

“What are you doing!!?!” Katie asked in a panic, unable to see that far behind her, “get your hands off my ass!”

Kristen didn’t respond, she began pushing her hands into Katie’s stretching ass, her hands easily sunk into the black spandex buttocks, pushing it out and making it bloat and stretch in all other directions.

“You’re hurting me!! STOP!!!” Katie screamed.

Kristen said nothing, she put more pressure on her hands and brought each knee onto Katie’s extremely distended butt making it bulge and widen out even more.

“Oh my god what are you doing!?!!!” Katie hollered

Kristen stood up, keeping one foot on the center of each bulging bulbous butt cheek, they squeaked and groaned Kristen began slowly moving her body up and down, bouncing Katie’s ass.

“Stop Stop!!” Katie exclaimed, “get off of my ass! Its so tight! You’ll make it burst!”

“That would be cool I guess, but I just want to see how high I can bounce on it,” Kristen replied and began vigorously jumping on Katie’s butt, repeatedly slamming it into the ground.

“OH..OH..OHHHH…OHH…!!!!!” Katie screamed with each bounce, fearing her butt’s imminent explosion.

The inflation slowed even more as the spandex couldn’t began to reach its limit. Katie’s butt filled with even greater pressure and became increasingly firmer.

Kristen bounced higher, and higher, “Wow this is great Katie, your butt is like a trampoline!!!”

“OHH!!! OHHHHHHHH!!!! OHHHHHHHHHHH!!!! PLEASE STOP!!” Katie screamed “My ASS!!! OHHH!!!! ITS SO TIGHT!!!!!! ITS!!! OHHH!! GOING TO!!! OHHH!!! POPPPPPPPPPPPPPPPPPPPP!!!”

Kristen jumped one last time as Katie’s rear felt as tight as a balloon on the verge of popping.

“BOOM!” Katie’s drastically stretched spandex exploded off her. Kristen was thrown to the floor, and Katie’s ass jiggled uncontrollably, like a dropped water balloon. Her panties were long gone, lost in her all encompassing ass. The inflation in Katie’s butt picked up again, Katie screamed as her ass surged out another 6 inches getting even bigger, now free from restricting apparel. The entire inflation then slowed to a stop.

“Fine Fine” Kristen replied as she got off the ground. “It was getting too tight anyway” she said, as she wacked it which made a resounding thump.

“You fucking whore!” Katie screamed. “My butt is so tight! Call 911! Before it explodes!”

“Oh shut up,” Kristen replied, “You’re only pissed because your ass is bigger than your fucking fake tits.”

“UGhhhhhhhhhhhh…….The pressure is growing again” Katie moaned due to the growing pressure.

Her eyes went wide, “Oh…GOD” She looked down at her tits while simultaneously grabbing them.

“oh no no no no no!!!” Katie screamed, as she watched her hands begin moving away from her and feeling her breast flesh swelling into her hands.

“hahahaha, her fake tits are blowing up now too!” one of the girls pointed and screamed.

Her D cups began swelling at a rapid pace, quickly pushing out her tight cotton top, each breast grew to the size of an extremely tight soccer ball.

“Whats happening to me! My tits! My beautiful tits are ruined!” Katie cried out, still trying to hold on to her breasts in vain.

The inflation quickened, stitches began to rip in the shirt and each orb inflated to the size of a basket ball, growing bigger and rounder by the second. A rip formed in the middle of the chest of her shirt, revealing 10 inches her immense overstuffed tan swelling cleavage which was still growing and dying to pop free.

With each breath she took the rip increased in size, showing more of her growing cleavage and chest, which was now the size of two large beach balls. All at once her top burst off of her over pumped tits, and drifted to the floor, leaving her breasts bouncing in her extremely tight blue sports bra.

It no longer looked like a bra any more though – more like a belt. Her breasts had grown so large that they were simply clamped down in the middle by the bra, growing above and below it.

As the pressure, and Katie’s tits grew, she let out a scream of pain. “Get this bra off me now!!! It’s cutting my tits in half!”

A girl started to approach her, almost feeling bad, but Kristen grabbed her hand and shook her head. She pointed to Katie’s tits.

“There’s no way you’re getting the bra off those things.”

As the other girl looked over more carefully at Katie she saw why, the bra was so tight around Katie’s massive chest that each gargantuan boob began to pulsate, rumbling and vibrating with pressure as they continued to bloat.

Katie clenched her fists and teeth, closing her eyes in pain.

“BANG!!!!”

The sports bra burst free from her ever expanding globes.

Some of the girls jumped in surprise.

Her breasts wobbled violently in different directions in the air for a moment before slowing to a stop. They were perfect spheres without a bit of sag, and without restraints they were growing fast.

“OH NOOO!!!” Katie screamed as she watched her breasts balloon out in front of her.

The girls laughed at Katie’s new misfortune.

Her blimping breasts approached the size of her gargantuan rear and also came to rest on the floor.

The girls poked, pinched, and slapped her tits.

“Stop that! You’re going to pop me! Get away!” Katie yelled.

“They feel just like her butt, but even tighter!” one girl said.

The inflation slowed as room ran out in her tits.

“Oh godddddd, I feel so tight! Ughhhhhh!!!!!!!!!!” Katie screamed.

“Wow Katie,” Kristen said, “You’re everything you always wanted to be, all tits and ass!” she said as she gave her left tit a loud slap. Katie moaned in pain.

There Katie stood, almost completely naked, all except for a while vinyl belt, tightly hugging her still slim waist, and some unseen panties.

“Oh my god. It stopped!” Katie screamed, even though she could feel her tits and ass still filling with pressure. “You’re all going to be fucked when I’m back to normal, I’m going to turn you all in to the police!”

Some of the girls started to actually look a little worried.

“Well, I guess we’re not going to let that happen.” Kristen replied.

A look of confusion overcame Katie.

She was obviously immobile, and couldn’t see anything that wasn’t in front of her, but she could hear something being dragged across the gym floor behind her.

“What the fuck are you doing you bitch!?” Katie screamed.

Then she saw Kristen, and a fire hose in Kristen’s hand. Katie opened her mouth about to say something when Kristen jumped on top of Katie’s tightly stretched and tan globular tits and shoved the fire hose directly into Katie’s mouth. A Look of shock overtook Katie’s face.

“mmmmmmmPHHHMMMMMMPH!”She tried to scream.

“Good bye Katie”, Kristen said, climbing down from her tits. “At least you’ll go out with a bang!” She said as she patted the overinflated tits.

She turned on the fire hose, and instantly water began filling Katie’s stomach. But somehow she wasn’t drowning.

Her stomach began to get a little puffy, and then began to swell outwards, rolling over and under the constricting white belt, and filling fast.

“MMMMMMMMMMPHHPHHHP!!” Katie groaned in protest.

Her belly approached the size of lady 9 months pregnant being clasped down in the middle by the oh-so-tight belt.

BANG!

The belt exploded, letting her stomach swell freely, and push her seemingly weightless tits right into her face, almost smothering her.

He stomach quickly approached the size of a large beach ball, widening and rounding out in all directions, growing bigger and tighter by the second; her skin was stretched so tight it was almost becoming shiny.

Kristen placed her hand on Katie’s mammoth belly and pushed. She could hear the water sloshing inside.

“Wow” Kristen said, genuinely surprised. She left her hand on Katie’s stomach and watched as the pressure within it pushed out her hand.

“She’s getting so big!” Kristen exclaimed, “And her belly’s as tight as a drum, she’s probably going to explode any time now.” She said as she firmly jabbed Katie’s stomach. A slap and sloshing water echoed throughout the gym.

“MMMMMMMPH!!!!” Katie motioned, flailing her arms (which couldn’t reach the hose due to her gargantuan tits).

Her stomach pulsated, swelling even more, and began sinking down to the floor due to the weight of the water churning inside. As her belly swelled out and filled up more and more, her enormous abdomen reached the size of the three large beach balls combined and the overall weight began rolling Katie forward, right out of her shoes (which stayed stuck to the floor) until she was resting atop her giant tits and tummy.

“Woa” Kristen said in a daze as she stared at Katie.

It was a site to see, Katie’s little tanned athletic body, resting a top two breasts the size of Volkswagens being sandwiched into the ground, an ass that stood about 8 feet high on her backside and jiggled with the slightest movement, as she slowly raised due to her inflating belly which was now the size of a large truck, and looked ready to explode.

“Now this looks fun!” Kristen exclaimed. She had one of the other girls give her a lift as she climbed on to Katie’s back, pushing her stomach and tits into the ground even more, making their sides stretch out even more.

She grabbed two handfuls of Katie’s hair as she straddled her, leaning back into her tight rear end. Kristen began to sway front and back.

“Neigh like a horse Katie!” she screamed with joy, picking up pace, bobbing up and down, and slamming Katie’s ready to burst belly and breasts into the ground repeatedly.

She bounced and bounced, as Katie moaned in pain and swelled even larger, but became even tighter.

Soon Katie’s tits, ass and belly were too tight. Kristen’s bucking motion just became her bouncing up and down and causing the sound of sloshing water to fill the gym.

“MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMPHHH!!!” Katie tried to scream, her tits started bouncing violently and her butt began jiggling wildly, completely wide eyed, there were two ear piercing POPS! As her gargantuan tits burst, as she rolled forward her belly throbbed and then POP!! BANG!! Her enormous belly and ass, burst in all directions, sending Kristen to the floor and a torrent of water momentarily filled the gym.

All the girls seemed dazed and confused, not remembering why they were in the gym, or why they were wet..

Sarah, peering in the gym through a window in the door grinned.

“Wow, who knew inflation and mutiny spells would work so well together?”

She chuckled to herself and walked away.
