Lil' Sister Got Super-Sized!  Chapter Two: Clean and Jerk
by Gorgon
Second part of a new muscle growth story	


Rudy looked down at his little sister Lucy in awe! Mere minutes ago she was
just a normal eleven year old girl. But out of nowhere she'd transformed into
a muscle-bound powerhouse! Well rounded muscles had sprung up all over her
little body, and now she was hoisting him over her head with ease!

Lucy laughed as she put her sixteen year old brother back on the ground.

"This is amazing!" gasped Rudy, "How did this happen? Did you find some kind
of magic amulet or something? Or get bitten by a radioactive insect? Or touch
a strange meteor from outter space?" Rudy racked his brain for other superhero
origins.

"Nope." said his little sister, still flexing her amazing muscles, watching
them bulge up and down. "Not that I can think of. Hey Rude, look at this..."

Lucy began flexing her meaty pecs one at a time. Up and down, up and down. She
was wearing a hello-kitty t-shirt which now looked like it was sprayed on. She
laughed as the kitty's distorted head bobbed up and down with her flexing
pecs.

"How do you feel?" her brother asked.

"Super!" she said striking a massive crab flex. Rudy was in shock. Even though
she was younger and shorter than him, she was now WAY broader and THICKER.

"I mean, are you tired? You were pumping a lot of weight back there."

"Nope." she said looking back at Rudy's weight set, "In fact I feel like I
could go for another round... Wanna see if I can get even BIGGER?"

"S-s-sure." gulped Rudy. This was the most amazing thing he'd ever seen.

Lucy began pumping up with Rudy's weights again. This time, however, she
really put some effort into it-- grunting, groaning, straining and sweating.
Rudy's jaw dropped as he watched his little sister's muscles change again....

Downstairs their father, Buck, listened to the clanking weights with
satisfaction. Just last night he had snuck some experimental muscle growth
serum into his weakling-son's food. Finally, he'd have a big, jock to be proud
of! He smiled as he heard the heavy weights slam up and down followed by
louder and louder grunts.

"Hmm..." he said to himself, "...still SOUNDS like a girl... but at least he's
bulking up! Maybe the other kids won't pick on him now."

Upstairs, Rudy couldn't take his eyes off his "little" sister. Her body wasn't
getting any larger, but her muscles were becoming more pronounced. Baby fat
was receding to make way for chiseled, rock-hard muscles. Muscle groups were
seperating and getting more defined. Sweat ran down the grooves of her
striated muscle groups. She dropped the weights. They slammed into the floor.
Her body was huffing and puffing.

Rudy looked Lucy up and down. Her whole body glistened in sweat. His eyes went
up her diamond calves and past her thick sculpted thighs. Her t-shirt was
stretched out and pulled up like a Baby-T, revealing her armor-plated abs. Her
lats flared out like a cobra's hood. Her chest was two thick slabs of
muscle-engorged pecs. And her arms! Her arms were more defined then the best
MALE bodybuilder in the world-- scaled down and stuck on the body of a mere
eleven year old girl!

"How do I look, big brother?" Lucy asked, laughing her little girl laugh and
flexing an incredibly peaked double bicep pose.

"You're... you're HUGE!" stammered Rudy.

Lucy started cracking up and pointing to her big brother's crotch.

"Looks like you're getting bigger too, Rudy!" she chuckled.

To his embarassment, Rudy looked down to see that he was sporting some serious
"wood". He shyly tried to cover it up with his hands. But Lucy firmly grabbed
both of his wrists and held them apart. Rudy was powerless to stop her. Her
grip and strength were unbelievable!

"This is a riot!" chuckled little Lucy, "I gave my own brother a boner! Ha! I
must be one super-hot muscle-babe!"

"Lucy... please... cut it out, okay? This is bad enough already!"

"Kids!" called their mother from downstairs, "You better get ready for school!
The bus will be here in half an hour!"

"Okay, mom!" Lucy yelled back.

"Rudy?!" their mom yelled, "Are you coming?"

"Ha ha ha!" laughed Lucy, still holding her brother's arms away from his
errection, "He's not coming YET, mom!"

"Lucy!" Rudy snapped at her.

"C'mon Rudy," Lucy winked at him, "Today's your lucky day. I can't go to
school all sweaty like this. Will you help me in the shower? There're parts on
my back I don't think I can reach now."

With that, she turned around and spread her lats, revealing a sculpted,
super-sized back.

"S-s-sure, sis." gulped Rudy, his mouth going completely dry.

In the bathroom, Lucy kicked off her shoes, took off her socks, and unzipped
her plaid skirt. As it fell to her ankles, Rudy could clearly see his sister's
glutes for the first time. Plump, round, and powerful, ready to burst out of
her panties... he'd never seen a butt like that, even in his deepest
fantasies!

Still in her t-shirt and panties, Lucy stepped on to the bathroom scale. It
creaked under the massive young girl's weight. And when the dial stopped
spinning it rested at 152 lbs.! She stepped off, picked up her big brother,
and carried him over to the scale.

"Now let's see how much you weigh, big guy." she chuckled.

Rudy couldn't believe how effortlessly his little sister could carry him
around-- like some kind of rag doll! As she lowered him on the scale, Rudy's
weight came up as 121 lbs. His little sister now outweighed him by 30 lbs.--
and it was all muscle!

Lucy leaned over into the shower and turned the water on. She told Rudy to
turn around, she was going to get undressed. Rudy nodded and did what she
asked. He was in no position to argue with her-- ever again! But he couldn't
help peeking at the bathroom mirror.

Lucy pealed her sweaty t-shirt off of her over-developed body, revealing a
highly-sculpted, muscle-bloated back. She slid her panties past her big
rounded glutes. And then stepped behind the shower curtain.

In the shower, Lucy lathered herself up, running her hands across her body as
she took joy in exploring her new and improved muscles. Through the soapy suds
she caressed her firm six-pack abs, her thick-and-meaty pecs, her rock-hard
rounded shoulders, her large horse-shoe shaped triceps, her ludicrously peeked
biceps, and finally her Popeye-sized forearms.

"Hey Rudy!" she called out over the sound of the shower, "I could use some
help here!"

"S-s-sure thing." gulped Rudy.

He nervously pulled back part of the shower curtain. There was Lucy, her big,
broad back facing him. With one muscular arm, she covered up her chest, and
with her free hand she covered herself from below the waist.

"Well?" she asked coyly, "What are you waiting for, scrawny? Get scrubbing!"

Rudy nervously grabbed the soap and began rubbing his sister's big, broad
back. It was like a warm wall of solid steel. Lucy spread her shoulder blades,
and Rudy gasped as her back unfolded like a Japanese fan, getting broader and
broader.

"Lucy..." he stammered, "You're so BIG... and HARD!"

"I know!" she giggled, "It's all so cool! Yesterday I was just Lil' Lucy...
and look at me NOW! Even my muscles have muscles!"

Completely entranced by his little sister's massive muscles, Rudy starts
letting his hands wander, soaping up her firm, bulbous glutes.

"Hey buster!" snapped Lucy, "Watch the hands!"

In one quick motion, she took her arm that was covering her chest and
backhanded Rudy. Her brother went flying backwards, slamming into a wall, and
sliding down to the floor. Lucy grabbed a bath towel and wrapped it around
under her arms.

Rudy was dazed and hurt. He could already feel bruises forming where Lucy
swatted him and where his back hit the wall. He cowered in fear as his massive
eleven year old sister stepped out of the shower and started sauntering
towards him. As he lay on the floor, Lucy towered over him, her big, broad
form casting him in shadow. It was so surreal! A four and a half foot high
"heavy weight" bodybuilder with his little sister's cute face on top! Dripping
wet, wrapped in a towel, her sinewy limbs flexing with each motion.

"Rudy?" she asked, grabbing him by his shoulders and picking him up, "Are you
okay? I'm so sorry! I don't know my own strength!" Which was painfully
evident-- since Rudy hadn't uncurled himself from his cowering fetal position,
and Lucy was holding him aloft in the air.

Rudy slowly unrolled himself, putting his shaking feet back on the ground.

"I-I-I'm okay, sis..." he blurted out, "Really."

"I'm so glad you're all right!" she blurted out, giving her big brother a big
hug. Her cut, super-defined muscular arms circled around him, pressing him
into her rock-hard chiseled body like a vise!

"Don't worry, Rudy!" she told him, "I'll never hurt you again. I promise!"

"L-L-Lucy!" gasped Rudy, "T-t-too tight! Crushing me!"

"Sorry!" said Lucy easing up on her grip. The eleven year old scooped up her
sixteen year old brother and cradeled him in her big, buff arms. As she
effortlessly carried him to his room, she told him not to worry. She promised
to look after him and keep him safe from harm.

"Do you think you can keep Dad off my back?" he asked.

"Hmm... I don't think I'm big enough for that... yet!" she said with a giggle
as she gently put him down on his bed, "But I'll work on it!"

"And can I still feel your muscles?"

"Sure," she laughed, flexing a massive bicep right in front of him, "Try some
of this bad girl!"

Rudy started to fondle and feel the rock-hard bulge.

"ALL of your muscles?" asked Rudy.

"Don't push your luck!" laughed Lucy as she struck a massive and imposing crab
flex. Rudy watched in shock as her muscles expanded and swelled up to
ludicrous sizes... they became SO big that her towel popped off, falling to
the floor....
