Lil' Sister Got Super-Sized!  Chapter Four: Bully for Her
by Gorgon
Fourth part of a new muscle growth story

    A few hours ago, little eleven year old Lucy Billings had gone through an 
amazing transformation!  The night before, her father had slipped some 
experimental muscle growth formula into her brother's spinach-- spinach that 
she ate!  The next morning, after a little playful arm wrestling, and a work 
out with her big brother's weights, her muscles expanded, gaining mass and 
definition, enlarging to ludicrous sizes!  Soon, this four and a half foot 
sweet-heart had the physique of a professional heavyweight bodybuilder-- 
tipping the scales with 152 lbs of rock solid muscle!
    Since her little-girl clothes could no longer fit her, she had gotten 
dressed in one of her big brother's t-shirts and some bicycle shorts.  But 
even these were too small!  Her power-packed physique stretched them to their 
limit, showing off every sinewy curve, deep ridged cut, and diamond hard 
bulge!  She loved the feeling of power she now had, and couldn't wait to show 
off her buff bod to all the kids at school, but she DID want to keep it a 
surprise-- so she had covered herself up with a pair of her dad's sweat pants 
and one of his baggy sweat shirts...

    As she stepped off the school bus, she couldn't help but smile.  This was 
going to be an awesome day!  As she confidently sauntered to her class room, 
she heard the sounds of a struggle coming from behind a row of lockers.  She 
peered around a corner where she saw the school bully, Frank Nash, picking on 
one of her classmates, little Charlie O'Conner.  Frank had been held back for 
two years, and that not only made him the biggest kid around, but also very 
bitter to boot.  Charlie, on the other hand, was a scrawny kid, the shortest 
in the class, even shorter than Lucy.
    Frank had wrapped his big meat-hooks around Charlie's upper arms, lifted 
him off the ground, and was banging him against the lockers.
    "All right, shrimp," Frank barked, "You don't expect me to believe that 
THAT is all the lunch money you've got?"
    "Please Frank," Charlie pleaded, "that's everything!  I swear!"
    "Hey!" shouted Lucy, "Put him down!"
    "Keep out of this, Billings!" snapped Frank.  He was going to say more, 
but he suddenly got a look at lil' Lucy.
    "Shit!" he exclaimed, "When did you get so fat?"
    "It's not fat." she told him, confidently sticking her chest out, "It's 
all muscle."
    "Shyeah, right!" the bully laughed, "Now get lost, tubby!  Before I 
forget you're a girl and give you some of this too!"
    "Bring it on, jerk" Lucy scoffed.  She'd always been intimidated by 
Frank, but not today!  She was bursting from head to toe with large, rock 
hard muscles-- and it was time, she decided, that she put them to some good 
use!
    Frank let go of little Charlie, who fell to the ground in a heap.  He 
marched over towards Lucy ready to teach her a lesson.  She just stood there, 
her hands firmly planted on her hips.  She couldn't stop smiling.  Frank 
wasn't going to know what hit him.
    In one quick motion Franky jerked his hands forward to push her down.  
But when they made contact with Lucy's granite-hard chest, there was no 
'give'.  It was like he was trying to push down the side of a building!  He 
put his whole body weight behind him, but it was useless.  And Lucy just 
stood there, laughing.
    Little Charlie rubbed his eyes in disbelief!  He watched as Frank 
strained with all his might, trying as hard as he could to shove Lucy down.  
But she was literally an "unmovable object".  With one last grunt Franky gave 
it his all, but as he straightened out his arms, all that happened was that 
HE skidded backwards.
    "All right," said Lucy with a chuckle, "my turn!"
    With one hand she pushed Franky...  In a blur, he was down, and sliding 
twelve feet along the floor!
    "H-h-how did you do that?" asked Charlie running up to Lucy, and staring 
at her in awe.
    "Easy Charlie," she told him with a wink, "I've been working out."  She 
removed her backpack and pulled off her baggy sweatshirt, revealing her 
power-packed body.
    "See?" she said striking a double bicep shot.  Her muscles swelled up, 
pushing out the sleeves on her Ram's t-shirt.  Her lats flared and her pecs 
swelled out, pulling her shirt up and revealing a mega-cut set of six pack 
abs.  Charlie drooled, worshipping her every curve.
    "Here," said Lucy, handing little Charlie her sweatshirt and backpack, 
"Hold on to this.  I think it's time someone turned the tables on this bully!"
    Charlie nodded, dumfounded.  He watched the rhythmic motion of Lucy's 
massive shoulders and back as she swaggered towards Frank.  Frank was still 
shaking off the shock of being pushed back a few yards by a little girl!
    He looked up in awe as the four and a half foot amazon strutted his way.  
Her mega-muscular arms swung at her sides!!  Her upper body was riddled with 
big, thick, sinewy meat-- showing deep definition even through her t-shirt!
    Not being completely stupid, Frank scrambled to his feet and ran away as 
fast as he could!
    "Hey, you big chicken!" Lucy shouted as she chased after him, "Where do 
you think you're going?!  I'm not done with you yet!"
    Frank hauled ass away from the lockers, jumping over trash cans and 
benches, until he got to the bike rack.  He fumbled at his bike lock, 
desperately spinning the dials, trying to remember his combination...
    He took a quick look over his shoulder...  To his horror, Lucy was still 
coming his way.  She grabbed one of the trash cans he'd knocked over.  And, 
like it was a mere empty soda can, she crushed it in her bare hands.  Her 
biceps and triceps bulged outward to ludicrous proportions!  She giggled and 
tossed the scrunched up trash can aside, like it was nothing.
    Frank gulped, his stomach knotting in fear!  But in one moment of relief, 
his bike lock opened!  He quickly unthreaded the chain, hopped on his bike, 
and pedaled away like mad!  Lucy gave chase!  In a mighty bound she hurdled 
the benches and then the bike rack.  She pumped her massive legs harder and 
harder, running at an incredible pace!
    Frank pushed his bike for all he could get.  As he rushed down the 
street, he looked back again...  To his horror, the eleven year old amazon 
was catching up to him!
    Lucy couldn't believe how fast she was running!  With her new amazing 
physique she could probably put every Olympian sprinter to shame!  As her 
heart continued to pump and pump, the amazing growth serum in her system 
pulsed faster and faster through every muscle in her body!  She could feel 
her body swelling up again!
    Her already densely packed legs plumped up even more!  With a quick snap, 
her bicycle shorts burst apart under her sweat pants, quickly followed by her 
little girl panties!  Her pecs were inflating outwards as well, filling up 
with more and more muscle!  Her back was erupting outwards getting thicker 
and thicker, harder and harder!  Her arms were expanding at an insane pace!  
Her biceps, triceps, and forearms were growing larger and larger by the 
second!
    Against such an onslaught of expanding muscle, Lucy's shirt never stood a 
chance.  Soon, a tiny tear became a loud rrrrrrrip!  Rock-solid amazon-girl 
flesh exploded its way out of every inch of fabric!  When Frank saw Lucy's 
massive upper-body bust out of her top, he was so shaken, he lost his balance 
and both he and his bike wiped out.
    Before Frank realized what was happening, Lucy was picking him up by his 
belt with ONE HAND!  Frank kicked and wriggled but it was no use!  The short 
stocky muscle goddess held him aloft with ease, dangling over the ground.  In 
her other hand she carried his bike.
    Frozen in terror, Frank looked on helplessly as Lucy propped him up 
against a lamp post-- and then bent his bike around his waist, like she was 
tying him up with string!  Her muscles flexed up into mountainous peaks and 
rock-hard ridges as she continued to twist the bike's metal frame.
    Frank tried to speak, ready to beg for mercy...  but the words stuck in 
his throat as Lucy looked him in the eye with a mischievous smile, and then 
struck a massively muscular pose!  Her muscle-bloated body was a sight to 
behold!  She no longer had the figure of a heavyweight bodybuilder, but 
rather that of a super-mega-heavyweight!  Who could believe that so many 
gargantuan muscles could be packed onto the frame of a four and a half foot 
tall little girl?!  She let her hands roam over her body, enjoying her new 
massiveness.  She giggled as she squeezed her now super-sized, humungous 
bicep, it was easily over 22 inches-- and oh so THICK and HARD!
    "Pretty big, aren't I?" she asked the restrained bully.
    "Y-y-you're HUGE!" stammered Frank.
    "Thanks," she laughed, "That's quite a compliment coming from a guy as 
big as you.  In fact, I'd say you're even bigger than my scrawny older 
brother, Rudy...  Y'know, that gives me an idea."
    And with that, Lucy stripped Frank down to his undies.  His shirt was a 
little tight, but once she tore off the sleeves and made a rip down the 
front, it was a more comfortable fit for her massive frame.  After all, she 
didn't want to walk around without a top!
    She emptied out Frank's pant pockets, taking all of his cash.
    "I hope you don't mind me taking YOUR lunch money," she tittered, "but a 
girl as BIG as me has a BIG appetite!"
    And with that, she struck a massive crab flex!  Her body seemed to almost 
double in size!
    "Any objections, Frank?" she asked with a wicked grin.
    "N-n-no!" stuttered the near-naked bully, still wrapped around the lamp 
post by his own twisted bike.
    "See you around, loser." she laughed as she headed back to school.  Frank 
continued to kick and flail, but to no avail.  Lucy couldn't wait for the 
other kids at school to see how massive she was!  And her brother, Rudy too!  
If he was surprised at how big she was this morning, just think how stunned 
he'll be when he sees she's gotten EVEN BIGGER!!!
