Little Katie: Chapter 3

Chapter 3: The Snowball Effect

Katie had been sitting in her car for the past twenty minutes, she squirmed around trying to fit her seatbelt around her bulging outrageously busty breasts that were barely contained in her red tank top. She had quickly snatched up some of Annette's clothing before heading out, but even her clothes strained to fit her now being over six inches taller and several cup sizes larger than her sister, or at least she thought she was to her knowledge.

Her sister's red tank top strained as it was stretched over a black t-shirt that was hugging her now curvy body tightly. Her sister's black legging had a few holes in them around the thighs, which were masked mostly by the red box patterned skirt she wore over it, which was double wide, made for larger girls. Katie giggled to herself realizing that her sister had been hiding this insecurity and was embarrassed by being a larger girl.

Katie reveled in it, feeling a bit excited she gasped as she watched her perspective jolt upwards at least an inch, now 6'1. Starting to feel warm again she quickly ignored the feeling and she put herself together and started the car. She turned her head to look behind her as she went to pull out the driveway.

She tilted her head trying her best to look out the back, and just ended up guessing her way out, she put her foot on the gas as the car bolted out the driveway. Not realizing her new strength and size, accidentally slamming on the gas, she startles herself and then starts laughing.

"Oopsie! I gotta be more gentle...giggle" Katie turned on the radio, listening to a pop song as she sang along. "Just pop, pop... pop your top! Pop, pop... pop your top!" Her breasts bounced along with each pump of the beat, slowly expanding outwards and becoming more sensitive, she felt a warm tingling sensation surround her body, travelling slowly and sensually towards her chest.

The sensation got stronger as she slowly stopped singing along and started licking her lips and rubbing against the steering wheel. She turned the radio up, feeling the beat pump through her stronger. The seat under her creaked a bit as the car readjusted to her sudden growth spurt, now 6'3.

She felt herself pump up a few more inches, now feeling a lot of pressure on her head as it touched the roof of the car. Her breasts and nipples began to tingle, sending sexual vibrations through her body, she struggled to keep her eyes open as she continued to drive, now merging onto the freeway.

Katie snapped herself out of the sexual trance as she pulled down the window, feeling a breeze touch her nipples, the final catalyst it seemed to the growth. Her breasts expanded, growing bigger and more juicy, they filled up the leftover space in her sister's large sized tank top, now bulging over, she feels it tighten up like a corset, growing to E cups.

"Oh...f-fuck...I'm still growing..." Katie tore off the tank top with one hand, tossing it behind her on the backseat.

"Much...better..." Katie now reaching back tries to unlatch her straining bra as she pulls into the school parking lot. Pulling in, she parks, seeing her hand almost able to entirely cover the stick, as she puts it into park. She hears a massive creak as she steps out of the car, and stretches tall reaching a few feet into the air,

"Mmmm...eep!" as another audible snap from her bra is heard, growing another inch to 6'5. Katie pays no mind, smiles and pulled the shirt, now up to her belly button up and tosses the broken bra into the car, and bounces towards class, feeling her butt constrict, as her legging become skin tight, showing off a massive juicy ass.

She thinks to herself, biting her juicy bottom lip,

"How much bigger...am I going to get...?" and keeps walking forward, feeling every step showing off each curve bouncing towards class.

Her panties were straining beyond belief, they were hardly noticeable now as her ass sucked up most of the flexible fabric looking more like a thong beneath see through dark leggings. Her front half had now looked extremely slutty, her sisters shirt had been just treading the line above her now E cup breasts, her nipples protruding holding the fabric like the peaks of two massive jiggling boob mountains.

Her leggings had several tears and holes, especially around the thighs, which now were even thicker than her mother's, she looked voluptuous and angelic. Her panties were fairly wet, leaving a dark spot over her vagina, which was now almost visible through her skin tight leggings. Katie bounced into the room, noticing the few inch gap between her and the door frame, then quickly ran to her seat, which creaked loudly under her new size.

The professor paid no mind, he just simply continued on and yawned, not realizing it was the same tiny Katie that had shown up to lecture yesterday, on the first day of class. History class was boring, but Katie had a blast blowing kisses to hot guys who were incredibly confused and horny, most of them after a few glances at her had them asking to go to the bathroom, she was acting crazy and she loved every second of it.

She was rubbing her wet pussy with a pencil, licking it delicately, and nibbling on it, seducing every straight guy in class, between hiding moans she grew a few more inches as the one hour lecture droned on, slowly gaining inches as she quietly moaned, now 6'9 and built like an amazon. 

The girls in the classroom were furiously gossiping through text with one another, getting extremely jealous. Some of the ladies started to play with themselves involuntarily, like she had some seductive aura that was infecting them.

She got up and walked past everyone and then ducked her head out the doorway. She felt powerful walking to the next class, her torso was above most short girls, she couldn't even see them beneath her huge breasts, swaying and bouncing under her braless shirt. Everyone was staring at her massive underboob, bouncing around without any control.

She was struggling to control her emotions in her english class, she was seated close to her crush, Desmond, a long haired, latino soccer player. Desmond didn't know Katie, but that was even better for her.

She stared as Desmond and turned to her, she reached down seductively and tore open a hole around her panties, exposing her soaked panties, they were riding up her pussy, wet from the constant rubbing up and down as she pulled on her panties even harder. She moaned began to rub her pussy mid lecture, feeling her clothes tighten and start to rip more.

"...Bigger..." Katie whispered to herself as she felt her legs get longer, leaving more tears in the fabric. Her ass swallowed the chair under her, flesh was bulging out the sides of the small school chair, she used to feel small in.

She moaned loudly growing another few inches, now 6'10 feet tall, her skirt had torn off mid lecture followed by her bra and tank top, shredded right off as her bulging curves expanded outwards. Mrs. Cooper, the english teacher was a short crotchety lady, who only stood at a mere 5'4. She screamed

"Young lady! Go to the principal's office this instant!" Katie rolled her eyes, and stood up and towered over her for a moment and then began to cum in front of the class.

"Or what?! ...ugh...moan" Katie gripped herself, feeling herself get faint as she planted her jiggly butt onto the teacher's desk.

"F-fuck...oh my...god...moan" Katie felt her body grow again, another inch, breaking 7 feet tall, now focusing on her ass, thighs, and legs, which all became thicker and juicer , until she was able to sit down on the desk and plant her feet comfortably.

She felt her feet touch the floor as her slip on shoes couldn't bear the strain anymore, they snapped off. Without a word, she got up and headed towards the door, which was up to her collar bone, she laughed and reached a long arm through the doorframe and ducked under it.

The school felt like an elaborate jungle gym, everywhere she walked the ceilings, were too low. Katie struggled to contain any form of decency as she crawled into the principal's office on all fours, making groaning noises.

"You're huge!" shouted Principal Johnson, "How did this happen!? This is crazy!" Katie stood at her full height of 7'4, over him, he was a tall guy at 6'5, but he was absolutely dwarfed by her size. Her breasts swayed in front of his face as she reached down and grabbed his balls tightly.

"I'm Katie Banks, put me down with a passing grade in all my classes and I won't tell your wife I sucked your cock." She nearly came at the thought.

"My what?! Excuse me -oh!" "Your cock, inside my juicy mouth, now moan, don't keep me waiting..."

Katie unlatched his belt and whipped out his big dick, it was a bit small for her now, but it was certainly the biggest she's ever seen. She placed a single one of her huge fingers on the tip of his erect dick.

"Oh and can I see your phone...thanks..." Katie started sucking, carefully licking and playfully sucking his dick, while she dialed the number she remembered she saw on the GTS Max package.

"Mmph..your...wallet...sir" Mr. Johnson leaned back on his desk as he scrambled for his wallet, she reached for the card, listening to the woman on the phone giggle between hearing moaning and gasping over the line. He came in her mouth, she swallowed it all and then giggled, now reading the card information.

"Yeah...like the biggest you got giggle!" Katie cleaned herself, licking every speck of cum that was on the edge of her lips and stood up, putting the man's head between her large breasts.

"Thank you! smooch" Her lips pressed against his forehead.

"GTS? I never heard of that." He was flustered and being smothered.

"Yeah well, thanks, I'm gonna go home now." She grinned after licking her lips.

"Wait... what?" "Remember what I said! I gotta go now, bye! smooch" Katie tossed his wallet back onto his desk, kissing him on the cheek and headed into the parking lot.

The principal quickly dressed himself and started to sweat as he sat down at his deck and started typing in his password to alter Katie's grades, after the deed was done, he smiled to himself thinking nobody ever got a blowjob from an actual giantess amazon.

She squeezed into the car and buckled herself in, feeling the car seat crack again as she slammed on the gas and raced home. She closed in on the house, as the car seat finally snaps. She falls back feeling her boobs bounce towards her face, feeling her head rub the back of the backseat.

She lifted her huge body off the broken seat, now noticing her huge difference in size as she grabbed the hood of the car and spun herself out. She hovered over the top of the sedan, that was up to her waist now and started nervously giggling to herself while turning red, realizing she destroyed most of the interior of the car, including the tires outside had been warped from her increasing size had also massively increased her weight, along with her huge bust and juicy thighs.

She turned and strutted towards the house, leaving huge foot sized imprints on the grass. She stopped fooling around and ran towards the door in a heartbeat and grabbed the large black box, still shocked by how fast it was delivered. Holding the box under one arm, it felt exhilarating as she opened the front door in anticipation for what could possibly happen next.
