Lil' Sister Got Super-Sized!  Chapter Five: Grading on her Curves
by Gorgon
Fifth part of a new muscle growth story

    Lil' Charlie O'Connor sat in shock in the school yard.  He couldn't 
believe what he'd just seen!  Before yesterday, he and Lucy Billings were the 
smallest kids in their class.  They were still the shortest kids-- but now 
she had to be one of the biggest and thickest kids in the world!
    Mere moments ago, Charlie was being picked on by Frank Nash, the class 
bully, and Lucy stepped in and saved him.  For some reason she was wearing a 
big, baggy pair of sweats.  After she challenged Frank, she took off her top 
and revealed that she was now sporting a massively muscular upper-body!  It 
was bizarre!  Even though she was only eleven years old, she somehow 
possessed the physique of a heavyweight bodybuilder!
    Little did Charlie (or Lucy) know, but the night before Lucy's father had 
snuck some experimental muscle growth formula into her brother's spinach-- 
spinach that she ate!  Now she was growing stronger and more musclebound all 
the time!  When Frank saw how incredibly buff Lucy was, he bolted, and she 
gave chase.  This left Charlie alone, holding onto Lucy's sweatshirt and 
backpack.
    With Lucy gone, Charlie began to fantasize about his amazon friend, 
imagining her as some kind of superhero.  In his mind, her muscles were even 
larger, bulging off her body.  He pretended she could fly and bend steel in 
her bare hands!  Bullies like Frank could try shooting her with guns and the 
bullets would just bounce off her!  She'd just laugh, pick them up with one 
hand, and hurl them into space....
    Charlie was snapped out of his daydream when he heard Lucy's sweet voice 
say, "Earth to Charlie.  Come in Charlie."
    He spun around... and there she was, even BIGGER than he'd just imagined 
her!  In the time since Charlie had seen her, Lucy had gone through another 
muscular growth spurt!  She'd grown out of her last t-shirt, and now had on 
the shirt Frank had been wearing.  Of course she had to rip off the sleaves 
to make way for her bulkier, bulging, muscle-bloated arms.  And she also had 
to rip open the collar to give her thicker meatier pecs some room to breathe!
    "Charlie?  You okay?" asked Lucy, her sweet little eleven year old face 
smiling from atop her power-packed physique, "If you're worried about 
Frank... don't.  I don't think he'll be bothering you any more.  Charlie?  
It's okay to breathe, Charlie."
    "Lucy!  What's happened to you?  You're... you're... HUGE!"
    "Hee hee!  Everyone keeps saying that," said Lucy while flexing her pecs. 
 Charlie watched on in awe as they bobbed up and down, in and out of Lucy's 
makeshift collar.
    "How did this happen?"
    "I don't know, but isn't it cool?  I just woke up this morning and felt 
all-- BAM!" said Lucy while striking a crab flex, her whole body seemed to 
double in size.  If it was possible, Charlie's eyes bulged out even farther.
    "And now..." said Lucy while flaring out her cobra-head lats, 
"...whenever I work out..." she pulled up her shirt and bunched up her 
super-six-pack abs, "... I get bigger AND buffer!" Lucy wrapped up her 
impromptu posing routine by pumping up her rock-hard horseshoe triceps.
    "Can I...  can I..." stuttered Charlie while tentatively reaching out 
towards Lucy's right arm.
    "You wanna feel this bad girl?" asked Lucy with a wink and a giggle, "Go 
ahead, Charlie.  It won't bite."
    Lucy held her arm straight out and Charlie squeezed it with both hands.
    "It's so hard!" gasped Charlie.
    "Hey, it's not even flexed." Lucy bragged.
    "H-how strong are you now?" asked Charlie.
    "You holding on?"
    "Y-y-yes."
    "Lift up your feet." she told him.
    Charlie raised his legs and hung there, swinging in mid-air, suspended by 
his friend's massive outstretched arm.
    "Wow!" Charlie exclaimed.
    "That's nothing," Lucy laughed, "Check THIS out!"
    And with that, Lucy began to flex her bicep up and down.  The extension 
was unbelievable!  Her arms swelled up to over 22 inches!  Up and down, 
taking Charlie along for the ride, over and over again.
    "This is INCREDIBLE!" Charlie blurted out as Lucy's diamond cut bicep 
peaks surged and lowered under his grip.
    With a subtle twist of the wrist, Lucy looked at her watch.
    "Oh my!" blurted Lucy, "Look at the time!  We are so late!  Did the bell 
already ring?"
    "I think so..." said Charlie, who was still amazed, and STILL hanging off 
of Lucy's bicep.
    With her left hand, Lucy plucked Charlie off of her right arm and placed 
him on the ground.  She picked up her sweatshirt and backpack and asked 
Charlie to join her.  She needed some help with
something.  Like a trained lapdog, Charlie followed her... all the way into 
the girls bathroom....

    Charlie waited patiently as he heard Lucy unzip her backpack and shuffle 
around inside one of the bathroom stalls.
    "Are you okay in there, Lucy?" he asked.
    "I'll be out in a second...  I'm changing."
    "You're growing AGAIN?!"
    "No, silly!  Just my outfit."
    And with that, the stall opened, and out stepped Lucy, dressed only in 
her mother's two-piece bikini.  Charlie's jaw nearly hit the floor!  He 
looked on in awe at Lucy's amazing physique!  Here she was, a four and a half 
foot tall, eleven year old girl with the body of an ultra-heavyweight 
bodybuilder!  Even though they were about the same height, he felt so frail 
and small next to his gargantuan, sinewy friend.  She could fold him in half 
and still fit four of him into one of her mammoth legs!
    "Oh my God!" shrieked Charlie.
    "Technically, Charlie, I'm  a 'goddess.'" Lucy corrected him, while 
firmly planting her hands on her waist, "A 'muscle goddess' to be precise."
    "L-L-Lucy..." Charlie gulped, "...are you going to go to class like 
THAT?!"
    "No.  THIS is for today's Show & Tell.  I thought I'd put on a little 
muscle show.  What do you think?"
    "Oh boy!"
    "Well, that answers that," giggled Lucy as she pulled a bottle of baby 
oil out of her backpack, "Now how would you like to help oil me up?"
    "OH BOY!"
    Lucy held the bottle over one of her thick, muscle-bloated legs.  She 
squeezed the baby oil onto her engorged thigh.  It trickled over the enormous 
curves of her muscles and slid down through her leg's sinewy grooves.
    Charlie anxiously ran his hands over Lucy's enormous limb.  There was no 
give.  Her leg was not unlike a pillar of marble.  Lucy loved the attention 
as Charlie wordlessly moved his hands across her muscle-bulging frame.  As he 
went from limb to limb, from body part to body part, Lucy would flex making 
that part expand and harden, causing ripples and striations of chorded muscle 
to swell and separate.
    She watched herself in the bathroom mirror and marveled at how big she 
was now.  She was so much larger than she was this
morning.  Lucy thought of her wimpy brother Rudy, and how this change was 
going to blow his mind!  
    When Charlie was finished, Lucy asked him for another favor.  She placed 
him infront of her and asked him to flex.  Charlie struck a double bicep 
pose.  There was no muscle to be seen on him at all.  Lucy asked him to hold 
that pose.  Then she struck a double bicep pose behind him.  Every muscle on 
her body perked up and swelled to ludicrous sizes, the oil accentuated every 
cut and groove.  She laughed at the comparison.  She could easily fit him 
inside her-- like a Russian doll.  She tried to guess how much larger she 
was-- easily five times, six times, maybe even ten or twelve times bigger!
    "You are so HUGE!" gasped Charlie.  He couldn't take his eyes off the 
mirror.
    "C'mon," Lucy told him, pulling her dad's baggy sweats back on, "Let's 
get to class."

    Meanwhile, in Lucy's class, Show and Tell was already in progress.  One 
of the students, Philbert, was showing his rock collection.  Lucy's teacher, 
Mr. Pitt, pretended to listen on.  He mumbled the odd words of interest and 
encouragement, but really he was sneaking a peek at a magazine under his 
desk... a bodybuilding magazine.  Mr. Pitt was a scrawny little man who 
secretly worshipped female bodybuilders... little did he know, but today his 
fantasies were going to become real....
    As Philbert finished his presentation on volcanized rocks and geodes, 
Lucy and Charlie wandered into class.
    Mr. Pitt looked up.  He was more than a little cross.
    "Why Ms. Billings and Mr. O'Conner," he clucked, "how nice of you to join 
us."
    "Sorry we're late Mr. Pitt but..." began Lucy, but Mr. Pitt cut her off.
    "I hope you're ready for your presentation Ms. Billings," he told her, 
"because you're up."
    "Okay, Mr. Pitt." giggled Lucy, "You're the boss."
    As she walked up to the front of the class, some of the students 
whispered to each other.  Did Lucy look different today?  She was looking 
really... heavy?  Why was she wearing sweats?  Why were they so big?  Was she 
always that fat?
    Lucy pulled a small cd player out of her backpack and put it up on Mr. 
Pitt's desk.  She explained that her presentation was set to music.  She set 
the cd player to repeat one track and then played Brittney Spears' song, 
"Stronger."  As the music started up, Lucy explained that she'd recently 
taken up a new hobby... bodybuilding, and she wanted to show off her results. 
 Students immediately started laughing-- figuring it to be some kind of joke.
    Mr. Pitt told everyone to settle and ordered Lucy to take her seat, this 
had gone on long enough!  But suddenly, the words stuck in Mr. Pitt's 
throat-- and all the laughter stopped-- as soon as Lucy stepped out of her 
sweat pants.
    "Holy shit!" yelled one of the students.
    "My god!" screamed another as Lucy leapt up onto Mr. Pitt's desk.  She 
squatted, stood on her tip toes, and flexed her super-massive calves.  Mr. 
Pitt fell down in his chair in shock.
    Lucy jiggled her glutes in his direction, and then flexed them into 
bulbous, rock-hard globes of steel.  Mr. Pitt was instantly errect.  And that 
was before Lucy had reached for her sweat shirt and flung it off...
    A gasp came out across the class as Lucy stood fully revealed before 
them: an eleven year old amazon muscle goddess!  Her engorged, muscle-bloated 
body glistened from the baby oil that carressed her every pumped and bulging 
curve.  She struck a crab flex and her body expanded even further.  Mr. Pitt 
drooled as he watched Lucy's back tense up, riddled with muscle after muscle 
after muscle.
    Lucy placed her hands down on the desk, and then raised her legs to her 
side, supporting her entire weight.  She started to sing along with the song, 
"I'm stronger than yesterday..."
    She smiled as she effortlessly rolled her body up into a handstand, 
pointing her toes towards the ceiling.  Now upsidedown and facing Mr. Pitt, 
Lucy winked and asked him how he was enjoying the show.
    "P-p-please go on." pleaded Mr. Pitt in a soft, almost inaudible voice.
    "You want to see more?" said Lucy playing with him.
    "Yes please." said Mr. Pitt, biting down on his lower lip.  He placed his 
female bodybuilding magazine over his lap to cover his errection.
    "You're the boss." said Lucy again, through pursed childish lips.
    Lucy pivoted her body slightly, separated her legs into an open scissor 
formation, raised one of her muscular arms, and then, to everyone's surprise, 
began pushing her entire body weight up and down with one hand.  Everyone 
"ooh-ed" and "ahh-ed" like it was some kind of fireworks show... But Lucy was 
getting bored.  It was all to easy.  She pushed down hard on the desk and 
vaulted herself back to the front of the class.
    "Wow!" gasped Philbert, "You are SO strong!"
    "That's nothing," bragged Lucy, "Watch THIS!"
    She picked up the volcanic rocks and geodes from Philberts desk and one 
after another, crushed them to powder!  One with her grip alone!  One between 
her gigantic thighs!  And, most impressively, one between her bicep and 
forearm.
    Philbert gasped.  Lucy apologized for pulverizing his rock collection.  
Philbert said the super-strength display was more than worth it!
    "Um... what can I show you now?..." Lucy asked aloud.
    "Hey Lucy," Charlie called out, "why don't you grow some more muscle!"
    "Hmm... I dunno, Charlie." laughed Lucy, "I don't think I've got room on 
this bod for more muscle!"
    "Y-y-you can DO that?" coughed Mr. Pitt, "Just GROW more muscle at will?"
    "Yeah!" chimed in Charlie, "But she has to work out first."
    "PLEASE!" begged Mr. Pitt, "Please do it for me... I mean... for us!"
    "You guys really want to see that?" Lucy asked the class, her hands 
firmly on her hips, her muscular body gleaming under the classroom's 
flourecent lights.
    The class cheered!
    "Grow!  Grow!  Grow!" they chanted.
    "All right!" she laughed, "You win!  Let's get HUMUNGOUS!"
    They all cheered!
    "Well... I don't see any weights around," Lucy chuckled, "So you guys are 
going to have to do."
    She ordered Mr. Pitt and the heaviest students in the class to all pile 
up on top of Mr. Pitt's desk.  She got underneath it and with a mighty grunt, 
lifted the desk (students, teacher, and all) over her head!  She pressed the 
desk over her head over and over again!  And then she switched to squats!  
Later, she faced the ceiling, wrapped her legs around a support pillar, and 
then-- pressing the people laden desk over her chest-- she began to do ab 
crunches.
    Just like earlier in the day, her muscles didn't grow, but they got more 
and more cut!  Her muscles grew harder and firmer, deep cuts and pronounced 
veins formed across her entire physique.  It was awesome to behold!  When she 
was done, everyone watched in awe as she posed again.
    "Which way to the beach?" she joked as she struck various bicep poses.  
Her bicep peaks now had an extra inch or two of power behind them, easily 
rising upwards to 25 inches!
    Suddenly, Lucy felt VERY hungry.  She told the class that she had to 
refuel.  She could only seem to gain more mass if she had stuff to build it 
out of...
    Before she could finish her sentence, Mr. Pitt announced that it was time 
for lunch.  One of the class pointed out that school had barely just started. 
 Mr. Pitt snapped at the student, telling them to shut up!  He quickly 
regained his composure and said that if HE said it was time for lunch-- it 
was time for lunch.
    To Mr. Pitt's disappointment, Lucy put her sweatpants back on.  When Lucy 
saw his hound-dog expression, she decided to forego her sweatshirt and put on 
Frank's ripped t-shirt instead.  Mr. Pitt personally led the students to the 
cafeteria.  Lucy couldn't help but smirk as Mr. Pitt kept bumping into her on 
the way, clumsily trying to brush up against her shoulders, arms, and back.  
It was all so obvious.
    In the cafeteria, Lucy pulled out all of Frank's generous "donations."  
It cracked her up that she shook down the school bully for HIS lunch money!  
With these extra funds, Lucy stacked up six trays worth of food!  Everyone 
watched on in amazement as Lucy chowed down.  She was like some kind of 
bottomless pit, scarfing and devouring every morsel of food!
    Mr. Pitt asked if she was still hungry.  She told him that she could 
always eat some more-- after all, the more she ate, the bigger she could get! 
 Right there and then, Mr. Pitt emptied out his wallet and bought her all the 
food he could afford.
    "Thanks, guys." she said as the students filled up a whole cafeteria 
table with trays of food for the young muscle goddess.
    "It's no trouble at all.  I mean... you are a growing girl!" said Mr. 
Pitt, drooling.  In his mind he fantasized about Lucy growing bigger and 
bigger-- becoming the most muscular girl in history!
    Lucy continued to eat until it actually WAS lunch time!  When she was 
good and done, she let out a mighty belch.  Everyone laughed.  She was the 
center of attention.  Everyone hung on her every movement, marveled at every 
slight gesture and unintentional flexing of any muscle group.
    Mr. Pitt, now a drooling sycophant, leaned in and asked Lucy if she was 
ready to try growing again-- if she felt up to it, of course.
    "Is this still part of my Show and Tell grade?" asked Lucy 
mischievously-- knowing that she had the man eating out of the palm of her 
hand.
    "Oh no." he said, "You've already gotten an A on that."
    "Only an 'A'?" she pouted, puffing out her mammoth pecs.
    "I mean an A+!" he corrected, "THIS is for... Physical Education."
    "I think this should also count for math." laughed Lucy.
    "W-w-why math?" stuttered her slavish teacher.
    "Because," she chuckled, "I'm multiplying!"
    And with that, she struck her patented crab flex, straining her muscular 
physique till it appeared to double in size.  Mr. Pitt practically dropped a 
load right there on the spot.  Lucy giggled as she relaxed the pose, her 
momentary size-gain subsiding.
    "C'mon," she told her classmates while getting up from her seat, "Let's 
go to the school gym!  I think it's time I super-sized!"
    Everyone cheered and followed close behind.  As Lucy head towards the 
doors, she could hear the floorboard underneath her creak from all of her new 
excess weight.  She wondered just how much of that mass she could turn into 
muscle?....
