First Time, Part 3
By GBM
Kelly keeps lift weights for the first time


I followed my young, seven year old sister up the stairs. She had always been
a little self conscience about her height. At only three feet tall, she was
the shortest girl in her class. But she was also the prettiest, with dark
brown hair and sparkling, chocolate brown eyes. In order to try and help her
self esteem I had brought her down to the basement gym to lift weights,
figuring by lifting 10 pounds up and down that she would be happy. Well, she
sure lifted up 10 pounds. But she didn't stop there. She continued to lift
heavier and heavier weights, quickly lifting more than me and then more than
our Dad, who was the strongest man on earth. And muscles! With her seemingly
unlimited strength came impossible muscle size. She seemed able to flex up her
muscles as big as she wanted. She had just finished rapping a thick steel bar
around our Dad and giving him a spanking. Now we were heading upstairs,
looking for heavier things to lift in an attempt to satisfy her seemingly
insatiable appetite for more strength.

I watched as her muscles flexed and bulged with every step, mesmerized by the
size, density and muscle separation. Her body was like an anatomy chart on
steroids. We reached the top and Kelly slipped on some pink tennis shoes and
we headed into the kitchen. I also noticed that her muscles were reducing down
without the strain of the large weights. Was she going to shrink back down to
normal? She now looked smaller then when dad had come down the stairs, but
still had heavyweight bodybuilder sized muscles. I gave her a quizzical look.
She shook her arms a little and smiled up at me.

"Oh, don't worry big brother. I've still got the power. It's just easier to
walk around this way. I can't wait to lift some really heavy stuff."

She then walked into dad's room and grabbed a white t-shirt with Strong Man
written on it. How appropriate. The shirt was tight around her arms and her
chest, but still hung to her knees. She twisted around and giggled.

"This is dad's favorite shirt. Too bad I'll be flexing out of it later."

I sighed. The shock value of someone so young and small flexing up gigantic
muscles and lifting impossibly heavy weights was something she enjoyed in the
basement and now she was looking for a larger audience to impress.

We stepped out the front door and didn't have to wait too long for someone to
come by.

A familiar car drove up along our street and slowed down. Our neighbors, Brad
and Ryan pulled up in their Grand Prix and parked it on the curb. They were
brothers; Brad was going to be a senior and Ryan a junior. Both were state
caliber wrestlers. They were more impressed with our Dad then either of us. I
looked over to see Kelly smile.

"Those two boys were always mean to me. And Daddy never listened to me when I
complained to him. Wait until they see me now!"

Her muscles bristled and swelled slightly as she clenched her fists. I
swallowed. This was what I figured. Anyone who didn't treat her right was in
for a rude awakening. The boys got out of the car and walked over to us. Ryan
looked at me, ignoring Kelly.

"So, David, is your dad around?"

Before I could answer, Kelly walked forward, placed her left hand on the side
of her waist and pushed her right hip out. Her muscles bulged back out to male
heavyweight bodybuilder size.

"He's all tied up right now, Ry Ann!"

Both Brad and Ryan looked down at Kelly with shock. This time Brad spoke up.

"What the hell happened to you? Some type of bee sting? You're all swelled up.
Like you have huge..."

He didn't finish his sentence. I don't think he could. It was as if someone
had punched him in the stomach. Kelly gave them a small smile, brought up both
arms and squeezed out the most incredible double bicep pose they had ever
seen. Her arms exploded with fantastic musculature, showcasing a huge picture
perfect display. Only I knew she was holding back. But it was still shocking
to see her biceps bulge up to over 24 inches around with her initial flex. She
once again displayed proportionally the biggest biceps on earth! Kelly clearly
enjoyed the experience as she finished the sentence.

"You mean mmmmmmmmuscles!"

Brad's head jerked back as if he had received a sock to the face. "Damn girl,
your arms look huge!"

Ryan gave her a skeptical look. "What kind of steroids are you taking? Your
arms are almost half your dad's size."

Kelly chuckled softly. "These biceps can flex MUCH bigger than daddy's puny
muscles. In fact all of my muscles can get much bigger than daddy's. This is
just to show you guys that I'm bigger than either one of you."

Brad and Ryan gave her suspicious looks. Kelly held her flex, looking at one
peak and then the other, admiring her bulging biceps, but not yet willing to
flex them any bigger. Brad shook his head.

"No way is that shit real."

Kelly raised her eyebrows, pulling them both slowly into her trap. I took a
step back.

"Then why don't you two big strong boys come over here and see if you can
squeeze my little girl biceps. You know, to see if they're real or not."

Both boys slowly walked forward, continuing to eye her suspiciously. The shirt
looked strained, but was still down near her knees, hiding her thighs and
stomach. They looked her up and down, taking in her broad shoulders and her
melon sized pectorals, unsure of what really was hiding under the shirt. They
each reached down and brought their hands to her perfect peaks and tried to
squeeze down, quickly realizing that her biceps were steel hard balls of super
human density. Kelly smiled as the boys strained.

"Now Brad, you were saying something about how big daddy's arm is. Just how
big is your bicep? Maybe 16 inches? Get a load of these bad boys, they're 25
inches each! Over 2 feet around of pure girl muscle power! Way bigger than
your boy arms!"

Brad flushed red from the idea that she had bigger arms than him and was now
pressing on both sides, trying to dent her ball of steel. Ryan continued to
rub her arms, hoping to figure out the trick.

"What is this, some type of muscle outfit? There is no way you could have
gotten this big. No seven year old little girl could have muscles like this."

Kelly suppressed a giggle. "No boys, it's all me! All I needed to do was lift
some weights. In fact, do you two want to see something really cool?"

Both boys looked at her with the same quizzical expressions. They were using
both hands to grip the huge biceps of a 3 foot tall, 7 year old girl. They had
a good reason to look confused. Kelly simply gave them both an innocent smile
and batted her eyes.

"Well you'd better hold on tight, cause these babies have room to grow! You
think your biceps are big? You think Dad's biceps are big? Well watch this!"

She quickly tensed her fist and smacked her forearm into her bloated bicep,
easily sending more muscle into her super biceps, pushing them to over 30
inches around. The boys' arms jerked as her peaks shot up 3 inches! She
continued to pump her forearm, squeezing the bicep at the apex, stacking rock
hard muscle on top of rock hard muscle! Every flex added another 6 inches of
muscle! What an incredible super girl! The boys kept their hands on top of her
biceps, looking confused and impressed. Her biceps were quickly up to 42
inches around each, tearing the shirt sleeves up to her shoulders. They were
two feet tall and growing!

"Ha-ha! Like my biceps now boys? They're now bigger than daddy's! They're the
biggest biceps on earth! And I'm just getting started!"

Kelly continued her fantastic muscle bulging display, quickly pressing her
biceps up to 48 inches, then 54 inches, then 60 inches! Thin veins slowly came
to the surface as her biceps were now 5 feet around! The boys held on to her
bicep peaks as though their life depended on it. Their eyes were like saucers.
Kelly simply smiled and continued her little flexing routine, showing no
strain. Two more flexes pushed her bicep to 72 inches, causing her magnificent
bicep peaks to soar above the top of her head! The boys' arms continued to
jerk as her peaks had shot up another 6 inches! Her chest started adding mass
too, straining the shirt and outlining the powerful muscles beneath. The shirt
had risen to her hips, exposing the dazzling thighs for the first time. They
had quickly grown bigger than dad's and were cut better than any bodybuilder.
But the boys were only staring at her biceps as the peaks continued to climb
upward. Kelly chuckled.

"Now my biceps are 6 feet around! Neither of you is 6 feet tall! My seven year
old biceps are soooo big and sooooo powerful! And soooo not done growing!"

She continued to flex, adding even greater mass each time. Her bicep reached
80 inches around, another flex brought it up to 90 inches, then 100 inches,
110 inches and quickly up to 120 inches! Five quick flexes had doubled her
bicep size! Her veins pulsed and traced their way up her incredible arm. Holy
cow! A few simple flexes had brought her bicep back up over three times Dad's
previous world record! Kelly smiled at the stunned boys, whose hands were now
over the top of their heads, resting on top of biceps as tall as they were!
Their faces showed the strain as they pressed, pulled and pounded on her huge
biceps with absolutely no effect."

"Oh yeah boys, these biceps are real and they're the biggest ever! This is a
minor flex for me and it's three times as big as dad's! You see, these are no
ordinary muscles, they're Kelly muscles! And Kelly muscles are the biggest and
strongest muscles in the world and they demand worshipping from puny boys like
you two. You used to think you were so cool driving your car close to me when
I was on my bike. And you thought you were so strong with your wrestling. But
you're nothing compared to me now! So get on your knees and kiss my mighty
muscles!"

Both boys pulled their arms off of her biceps and took a step back. Ryan's
hands went into fists as he spoke up. "What the hell are you, you little
freak? We're not worshipping a little girl!"

Kelly's smile dissolved into a scowl. "Oh really? Then why don't you take your
best shot tough guy."

Ryan, not realizing that if her biceps were harder than rocks, the rest of her
body was also, didn't wait for another invitation and punched her hard in the
chest. I winced as a loud crack came from his right hand. Ryan pulled his hand
under his left armpit and yelled out in pain.

"Ow, ow, ow! Damn, it."

Brad was still confused, still not willing to accept the fact that my sister
was a huge, super strong, rock hard little girl, but was also not as short
fused as Ryan. He looked at Kelly who hadn't even flinched. Her chest had
swelled back up to near twin volleyball size and the thick striated muscles
pressed tight against the shirt, outlining her incredible musculature.

Kelly laughed, released her double bicep flex, reached straight out and
grabbed each boy by the front of his pants. They stiffened, but before they
could even reach out to grab her thick forearms she quickly jerked them
overhead in one clean motion. The boys flailed about, but Kelly's arms
remained rock solid.

"Ha-ha-ha! Did you think these muscles were just for show? I can curl tons! My
muscles are rock hard boys and they're way stronger than you two wimps! You're
not even in my league! In fact, it's time to show you just how strong I am!"

She brought her arms back and in another fast power move tossed both boys
forward into a high arc. They landed in their front yard over 100 feet away,
crashing hard on the grass. They stayed motionless for a moment, then sat up
and shook their heads. Brad looked like he was having trouble breathing; the
landing must have knocked the wind out of him. Ryan reached over and gripped
his injured hand.

Kelly placed her hands on her hips, admiring her handy work. She then walked
over to the front of their car. Her muscles remained incredibly huge from her
flexing, with the t-shirt strained near it's limit, riding up to the bottom of
her bulging pectorals, exposing her rock hard abs of steel!

"So boys, you must really like this car, huh? Well, let's see if it can stand
up to some Kelly muscle power."

She reached her right arm up high, causing her tricep to bulge to triple
horseshoe size. She looked directly at the boys who seemed perplexed. I shook
my head. Kelly smiled and brought her arm down with a crunch! The entire car
rocked as she slammed her arm straight through the hood and right into the
engine. She brought her arm back out, leaving the car crushed at the front.

"Boy, they sure don't make cars like they used to."

The boys reached out their arms and shook their heads, but didn't get up,
which was a smart move. Kelly looked at her fist, which showed no signs of
damage and walked over to the side of the car. She reared her fist back and
gave the car an uppercut. Her fist buckled the doors and flipped the car onto
the roof, where it smashed the windshields. Kelly laughed.

"That was easy! I'm going to have fun today!"

Kelly walked up to the car, grabbed the undercarriage and with one quick
movement, pulled the car over her head! Now I had seen her lift heavier
weights in the basement, but to see her lift a car over her head was still
scary and impressive. She turned around and looked at Brad and Ryan who
appeared ready to cry.

"Ha-ha! Your car is pretty light! I wonder if it's bendable."

Kelly brought her muscle packed arms closer together and the car screamed in
protest as she slowly bent the frame! The bumpers both started moving down as
she continued to pull her thick arms closer to each other! The remainder of
the windows cracked and shattered on the ground. The roof creaked as it bent
upward. Kelly continued to pull at the frame until the bumpers were near the
ground! Kelly giggled.

"Well, that's enough fun with your car. Guess I'd better put it in the
driveway!"

Kelly bent her muscular legs down and pulled the car toward her head and then
with one quick thrust tossed the car toward their driveway. It sailed silently
in the air until it crashed hard onto the driveway. The ruined car looked like
it was the loser in a demolition derby against a group of tanks. Kelly brushed
her hands and walked back toward me and then eyed Dad's Hummer.

"Ha! This looks like an even better test of Kelly muscles! Dad's Hummer
Xtreme! Let's see how heavy it is!"

She stalked over to side of the car, reached down and with a small groan from
the suspension, easily curled up the side of the car so it was only on two
wheels. Kelly laughed.

"Pretty light so far! Let's lift this bad boy up!"

She worked her way under the huge car, bending over a little to keep it from
flipping on its side. She reached the center, stood back up and hoisted the
huge car above her head with ease. She then brought the car up and down,
pressing it near her bulging, basketball sized pecs and back up at arm's
length. The car was loaded, so it had to weight over 20,000 pounds! 10 tons! I
watched with renewed awe as she pressed the huge car up and down over 10
times. I leaned over to see her smiling at me.

"Pretty cool huh? I can feel the weight get lighter with every press. My Kelly
muscles just keep on getting stronger. In fact, I don't even need both hands
to hold this up any more!"

Kelly pulled one hand down and was quickly holding the huge Hummer Xtreme with
only one arm! She then flexed the other arm into a devastating bicep mass that
nearly touched the bottom of the car! A casual flex had brought her bicep up a
foot past the top of her head.

"If you think this is cool, just watch this!"

She released her bicep flex, placed her other hand back onto the car and
pulled the car back down, squatting a little. She then pushed the huge Hummer
upward where it sailed 5 feet, 10 feet, 20 feet up in the air. Kelly brought
her right bicep back up and flexed down hard with a grunt. My jaw dropped as
her bicep soared upward to new heights! It was 100 inches around in a flash,
then 120 inches, then 150 inches, 180 inches and quickly 220 inches around!
Her bicep was three times her height in a heartbeat! What was she capable of?
I was about to find out as the Hummer fell back toward the earth. And crashed
onto her immovable bicep of doom! With a loud crunch the huge car was impaled
on her impossibly large super muscular arm! The frame was bent on both ends
and the side windows were cracked! I couldn't believe my eyes! A three foot
tall 8 year old girl had flexed up a bicep big enough and hard enough and
strong enough to hold a 10 ton car! Kelly laughed with delight.

"Oh, yeah baby! My mighty Kelly bicep is bigger and stronger than Dad's big
car! I'm holding 10 tons with my bicep alone! My power has no limits! Let's
see how big my bicep can get! I'm pushing his pathetic toy up past the roof!
Ha-ha-ha!"

I watched on as she renewed her bicep flexing routing, bringing her forearm up
and down, pumping more super human muscle into her engorged bicep, pushing it
higher than I ever could have conceived! With every smack her bicep had to
gain 24 inches in circumference and a foot in height! Quickly the car was
pushed up to 10 feet high, then 11 feet high as her bicep grew to 224 inches
around, then 248 inches around, then 272 inches around! Her bicep got thicker
too! I could hear the metal ripping as the huge car was pumped up higher and
higher.

"Ha! And you thought my bicep was big before! Look at it now! It's a foot
higher every time I pump it! I've got unlimited Kelly muscle power! Unlimited
Kelly muscle size! I'll crush anyone who thinks they can stop me! I'll destroy
anything that's thrown at me! And I'll lift the biggest things on earth!"

She continued to pump her mighty biceps bigger and the car continued to lurch
higher and higher! 12 feet high, 14 feet high, 16 feet high! Her bicep had to
be 400 inches around! The Hummer started to sink against her bicep and the
frame continued to rip and tear against her ever expanding bicep. One of the
windows shattered.

"Ha-ha-ha! There's nothing that can stand up to my mega Kelly muscles! The car
is now higher than the roof and my bicep is now 20 feet high!"

Kelly stopped flexing her bicep bigger and walked into the front yard, bulging
bicep and Hummer Xtreme in tow. She bent forward a little and angled the car
onto the roof! She then released her flex, pulling her bicep out of the car.
The Hummer tilted and then landed on all four wheels right on the roof! I
could here our roof creak under the weight as Kelly laughed so hard that she
bent over.

"Ha-ha-ha-ha! Let's see daddy explain THAT!"

I looked at my muscle bulging sister and sighed. She finally stopped laughing
as her muscles reduced back down a little. She wiped away her tears and looked
up at me.

"Come on, I know where I want to go next!"

"Uh, where is that?"

Kelly gave me an innocent smile. "The quarry! They've got some big machines
and huge rocks. Maybe enough stuff to test my Kelly muscles."

She started skipping down the street and I turned to take a last look at the
mess she had created in a few minutes. I saw two ruined cars, with one on the
roof and two stunned boys, still sitting in their front yard. I turned back
and had to pick up the pace to keep up with my little sister. The quarry was
about a mile away. They normally didn't work week-ends, but I had heard some
noise earlier this morning and knew that they must still be at it. Boy where
they in for a surprise.

As we quickly walked toward the quarry Kelly kept talking about how strong she
was and turned her walk into a strut as people drove by, eyeing the young girl
with the super muscular frame. Fortunately nobody came up to challenge her.

We reached the quarry and stood at the gate entrance. It was a thick chain
link fence with barbed wire on top. Kelly walked up to the fence and smiled.

"Ha! They really don't think THIS will keep me out do they?"

I didn't have a chance to respond as she walked up to the gate and wrapped her
small hands around some of the linkage. Kelly giggled when she pulled her
hands apart, causing the fence to ping as the metal quickly broke against her
superior strength. Kelly was tearing through the metal fence like it was weak
string. Her large muscles weren't even showing any strain. Within a few
moments a large hole was formed and she walked through. I quickly followed
behind. We saw someone near a large shack and Kelly marched directly over. The
large man turned to look at us. He was 6 foot 2 with broad shoulders. His had
on a white t-shirt, jeans, boots and a hard hat. He also had some type of head
set on.

"Hey, you two, what are doing in here? Did Joe leave the gate open again?"

Kelly smiled. "Naw, the gate was closed. My name is Kelly and this is my
brother David. We're here to test my mighty muscles."

The foreman gave her an incredulous look and then as he looked her over,
opened his mouth as Kelly brought her arms up into a quick double bicep that
caused all of her muscles to snap to attention. Her thighs and calves bulged
back up to double heavyweight bodybuilder size and her upper body expanded,
pulling the strained shirt half way up her ripped abs, outlining her huge,
striated muscles on her massive chest, back and shoulders. Kelly's biceps
expanded back up to 50 inches around, her incredible peaks rising up to her
wrists. The foreman was frozen for the moment with confusion, causing Kelly to
giggle again like the seven year old girl she was.

"Pretty cool, huh? But this is nothing. I can flex up MUCH bigger muscles than
this. And I'm really, really strong too. So strong that I haven't found a
weight I can't lift. So I figured I'd come here to see if there was anything
heavy enough to give me a good pump and cause my mighty muscles to REALLY
expand."

The foreman was still too confused to say much and looked over to me for some
help. I sighed.

"She's right. Those muscles ARE real and she really is super strong. I suggest
you let her lift some stuff here."

He was about to say something when he must have received a message in his ear
phones. He talked into the set and his voice was broadcast on speakers that
must have been placed around the edge of quarry. Kelly smiled, released her
flex and took a step toward the foreman, who was returning his attention to
Kelly.

"Say, that headset is pretty cool. Mind if I borrow it."

The foreman blinked a few times as he watched her muscles pulse and surge as
she walked forward.

"Um, I'm afraid I can't. Company policy."

Kelly smiled as she stood directly in front of the much taller man. She placed
her hands on her hips and gave him a penetrating stare. Her muscles tightened
audibly and grew bigger. The foreman opened his mouth, but said nothing. Just
as he was about to take a step back, Kelly grabbed the front of his pants and
roughly pulled him down toward her. His chest slammed into her diamond hard
pectorals with a thud. He let out a pained WOOF. Kelly plucked the headset off
his head and casually lifted the 6 foot 2 inch 220 pound man over her head
with ridiculous ease, using just one hand. He twisted a bit in a futile
attempt to right himself. Kelly laughed.

"You big strong men think you can stand up to a seven year old muscle girl?
Well you can forget it! I'm the biggest, strongest girl there is. I'm
soooooooo much stronger than you so called big, strong men. And since I am
going to keep getting stronger, you'll soon be worshipping my mighty Kelly
muscles like everyone else. But for now, have a seat."

Kelly roughly slammed him to the ground on his behind and he groaned a little
as he looked up at her bulging muscles and beautiful, seven year old face. Two
things that just didn't match, but were too close to deny. He wisely brought
his arms back to steady himself and stayed on the ground. Kelly snickered and
placed the head set on. She started walking out toward a large flat area where
a bulldozer was moving around some large rocks. As she walked toward the
bulldozer she started to flex up her pecs, pushing them up one at a time,
first the left and then the right, pulsing them bigger with each step. She
started talking into the microphone.

"Ahhhhhh! Time to power up the pecs. I can feel the power pore into them as I
flex them up. They're each bigger than basketballs and denser than steel!
Whoops, dad's shirt is starting to rip! The bottom of the shirt is up to my
super chest! There goes a tear down the side! Oh, look now. My pectorals are
as big as beech balls!"

We then heard a loud rip as the overstressed shirt finally tore away from her
super muscular frame, completely exposing the minefield of bulging back
muscles and rippling pectorals. And with each step toward the bulldozer, her
pecs grew bigger!

"Check out THESE mega boobs! Look at the thick striations! See how I can lift
them up and down a foot with every small flex! These Kelly muscles are primed
and ready to go."

Her chest was over 200 inches around as she stopped directly in front of the
bulldozer that was moving forward rather quickly. She planted herself and
flexed up her chest even bigger! Her chest had to be over 240 inches around!
Over 20 feet around! Each pectoral was now over four feet tall, pushing up
over the top of her head and into the ground below! She was presenting the
bulldozer with an eight foot wall of mighty seven year old girl muscle. Her
back continued to get wider with seething muscularity and her calves and
thighs pulsed to unearthly proportions, pushing away from her body with super
girl muscles. And we could hear the giggling as she saw the bulldozer
approach.

CLANGGGGGGGG!

The bulldozer came to an abrupt halt! The driver looked confused. He knew he
hadn't reached the rock he was driving toward. Kelly stifled a laugh and
flexed her gigantic pecs up some more as the driver pressed hard on the gas!
The treads were actually starting to spin on the ground as Kelly was exerting
more force with her chest than the huge earth moving vehicle could handle! And
with every passing second her chest grew even bigger! Kelly started giggling.

"Hee-hee-hee! You men think your mighty earth moving vehicles are big and
powerful! Ha! They can't match the power of my super Kelly muscles! I'm going
to charge up my chest bigger and stronger than you've ever seen! I'll show you
guys AND your machines what big and powerful are all about!"

The foreman and I gasped as Kelly pressed her chest bigger! 300 inches around
soon became 360 inches around! Then 400 inches around! The driver had the
bulldozer floored, but he was getting pushed back! The blade was pressing hard
into her chest, but was now deforming with a loud squeal into the shape of her
rising chest of pure power! Her pecs surged even bigger, up to 500 inches
around! Each pectoral was now nine feet high and pressed over the top of the
bulldozer plow! Her chest was 18 feet across and was now WIDER than the plow!
With her cleavage at nine feet thick, the bulldozer continued to skid
backward!

"This is EASY! My mighty chest can't be stopped by your puny machines! My
boobs are pressing into the hard ground like it was NOTHING! And my pecs are
bigger than the front of your huge bulldozer! Kelly muscles are the strongest,
most powerful things on earth!"

The driver began to panic as he saw the wall of flesh press up in front of
him. He finally let off the gas and jumped out of the bulldozer just as it
lurched upward, pressed into the air by the power of my little sister's
incredible chest! She laughed as her pectorals started growing bigger at an
even faster rate. Her chest was 600 inches around, then 700 inches around! The
bulldozer pressed higher in the air with every second, unable to withstand the
power of the giant wall of little girl pectorals! My mouth went dry as she
continued to press her chest bigger! 800 inches around, 900 inches around, to
1000 inches around! The bulldozer was standing straight up against her
gigantic, rippling, pulsing chest of pure power! Each pec was 20 feet tall!
Her chest was 40 feet across! I could see that her back had stacked on super
dense layers and had expanded to an impossible width of 10 feet across! She
was over 3 times wider than she was tall and her chest was almost SEVEN times
higher than the top of her head! Then with one more quick press from her
unstoppable pecs, the bulldozer crashed to the ground!

"Ha! So much for your powerful bulldozer! You could fit two of those things
inside MY super Kelly chest! You could press 10 bulldozers against my mighty
pectorals and they'd get pushed aside like the toys that they are! There's no
machine ON EARTH that is stronger than my chest! Just think how much weight I
could press with this much muscle! This much GROWING muscle! Ha-ha-ha!"

To my continued shock, Kelly continued to press her chest even BIGGER! The
bulldozer skidded across the ground, unable to slow down her ultra powerful,
throbbing, super striated pectorals! 1100 inches in circumference soon became
1300 inches, then 1500 inches, then 1700 inches, then 2000 inches around! OH
MY GOD! OVER 160 FEET AROUND! She had DOUBLED the size of her chest with only
a few incredible flexes! Each pectoral was over 38 feet high! 38 feet of
unstoppable cleavage pressed ahead, tearing up the ground and pushing the
bulldozer like it was a pebble up and over, crashing hard into the ground with
every tumble! Kelly continued to laugh as her chest continued to grow!

"So much muscle on such a little girl! Boy am I ever glad you showed me how to
lift weights big brother! I'm an unstoppable super girl now! Look at how big
my mighty chest is! And I can make it even bigger! Just watch!"

All I could do was watch as her chest surged past any conceivable size! Her
thick striations were like gigantic straps of pulsing super muscles, grinding
and surging bigger and thicker with ever breath! The earth below her crunched
and cracked and the bulldozer continued to tumble like a plastic toy! 2200
inches around soon became 2400 inches around! 200 feet around! I watched on as
the huge bulldozer got caught into one of her humongous pectoral striations
and was slowly being crushed into the ground below her monstrous chest of
devastation!

"Hee-hee-hee! Is that your huge bulldozer being crushed beneath my seven year
old chest? Why I do believe it is! My Kelly muscles can't be stopped! They're
bigger than a building and stronger than a hundred tanks! And growing even
bigger! And stronger!"

I fell to one knee as I watched her chest continue to grow to previously
unthinkable dimensions! Her chest pressed to 2600 inches around in moments and
with a loud crunch completely buried the huge bulldozer beneath her super
human pectorals of unrelenting power! And even THAT didn't slow down her
growth! Her chest pressed onward quickly, filling up the open area in the
quarry! Her chest swelled up to 2800 inches around! To 3000 inches around!
Bigger and bigger! When was she going to stop? I fell to my other knee and
leaned back as I continued to look up at her ever growing wall of pulsing,
super pumped pecs! I rubbed my eyes as her chest climbed to 3200 inches
around, then 3400 inches around! As they reached 3600 inches around Kelly's
giggles turned to laughter.

"So how's THAT for a pectoral flex! My Kelly muscles are over 70 feet high!
Ha-ha! That must make my cleavage 70 feet thick! There's NOTHING that can even
come CLOSE to this much raw power and size! My pectorals are super mega
muscles of fantastic glory! The biggest muscles ever dreamed! And I can feel
the strength, feel the power. The power to grow even BIGGER!""

The blood started rushing out of my head as she laughed manically. Her
pectorals continued their unthinkable mega growth. Tons of super human
pectorals muscle were layering on top of each other with every passing moment.
Bigger and bigger they spread! Her chest was soon 3800 inches around! Large
rocks in her way were crushed flat with a resounding crunch against the super
striation of her ultra mega chest! At 4000 inches around I almost cried. At
4200 inches tears started down my cheek. Kelly's laughing continued.

"Yes! More power! More size! And you guy's thought you had some powerful
machines around here! All of your machines are insignificant to my Kelly
muscles! My ever INCREASING Kelly muscles!"

I watched on with the look of someone looking at a skyscraper for the first
time. A sense of wonder, awe and dread raced around as her chest muscles
continued to multiply to 4600 inches around, to 4700 inches around and with a
satisfying sigh, her humongous, mind blowing super human chest extended to
over 4800 inches around! More than 400 freaking feet around! Each pectoral was
300 mind blowing feet around!

"I'd like to see someone try and top MY super Kelly pectorals of MIGHT! Look
at them David! My super mega ultra Kelly chest is 1200 inches high! 100 feet
of earth shaking, bulldozer crushing, gigantic mounds of bulging, surging,
super powerful chest muscles. The biggest pectorals in the UNIVERSE! They're
100 FEET TALL! 100 FEET THICK! AND OVER 200 FEET WIDE! HA-HA-HA-HA!"

I could only look on with dread, but as her laugh slowed, so too did her
muscle size. As her pectorals slowly reduced down, the crushed bulldozer soon
came back into view, along with the crater formed from her eight story
pectorals! I stood back up as her chest finally reduced back down to twin
basketballs of twitching might.

"Well as fun as that was, it's time to lift some more weight! I need more
power and strength to grow even BIGGER muscles!"

I let out a small "eep!" at the thought and watched as she turned and walked
toward a huge, fully loaded dump truck that must have weighed 30 tons. The
tires were four feet tall and Kelly only had to duck a little to walk under
it. She placed her hands on the undercarriage and with a ridiculously easy
push, pressed the giant weight above her head! She brought the large dump
truck up and down a few times and giggled.

"Ha! This huge weight feels light! I just keep getting stronger all the time!
It looks like another machine is weaker than my Kelly muscles! This truck is
so much weaker than my mighty muscles that its weight feels lighter than a
pillow! In fact, it's so light, let's try a little toss."

I saw Kelly lean back and to my continued shock watched as the huge truck was
launched toward the other side of the quarry, a quarter mile away, at an
alarming speed. Like a missile, the large dump truck and rock smashed into the
side with explosive force, disintegrating the truck and the boulders with a
loud blast. I shielded my eyes for a moment. When I looked back I saw a large
hole in the side of the wall and smoke trailing upward.

Kelly was standing in the same spot, smiling.

"Man, am I super powerful or what?" She then turned toward the large side of
the quarry that they would eventually expand to. The wall was 50 feet high
above her. What was she up to? As she got to the wall she looked up and down
the wall and reached her arms out. Kelly bent down and pressed her basketball
sized chest and small hands straight into the rock with a loud crack. She then
started to talk to herself.

"OK Kelly! Time to lift some serious weight!"

I watched as she pressed forward and up, causing a large crack to form along
the base of the thick wall. Kelly let out small, little girl grunts and the
crack began to expand, slowly at first and then with a loud snap, quicker. The
fissure continued to grow and chase on down the side of the huge granite wall
until it moved out of my eyesight. Kelly was pushing tons and tons of rock
with her titanic muscles! I watched as her muscles surged a little bigger
again, separating into savagely rippling super powered strips of young girl
might! Her pig tails pushed up and down as she continued to tug and press
against the rock. Even though I could see every inch of her huge muscles, they
still tapered in and out of her small joints, giving her a decidedly female
appearance. Kelly's calves were huge, throbbing balls of power that pulsed
back and forth as she moved up and down on her toes, looking even bigger
against her small ankles and knees. Her muscles then exploded back out into
monstrously rippling thighs and hamstrings that were comprised of thick strips
of astounding power. Her muscular, ripped glutes pulsed as she continued to
tug up and down. Her behind had destroyed her pants and sucked in her panties.
Her waist looked to be 20 inches around, but expanded with reckless abandon
into the widest, thickest, most muscular back ever seen. And it was reduced
back down to a mere five feet wide! Her triceps were stacked with layer upon
layer of incredible thickness, yet they narrowed into her small elbow and back
out into her Popeye sized forearms. My little sister had the biggest muscles
on the planet, yet there was still no doubt that she was still a girl.
However, I still couldn't believe that she could continue to lift heavier and
heavier weights. And what was she doing anyway? My wandering mind came back
into focus as Kelly was about to show me.

The huge crack was growing wider as Kelly started to giggle again. And then I
watched as a huge section of rock started to move upward as Kelly leaned back!
Good grief, how big was that rock? Kelly started talking again as the gigantic
granite slab continued to move up.

"Now we're talking some REAL weight! A REAL test of my Kelly muscles! This
thing must weight thousands of tons! It feels really heavy, but the longer I
hold it, the lighter it becomes! Ha-ha! My Kelly muscles are STILL getting
stronger!"

I watched with renewed horror as I finally got a good look at the rising rock.
It was 50 feet tall, 100 feet wide and as God as my witness, a HALF MILE long!
That mountain of rock had to weight MILLIONS of pounds! My little sister was
now as stronger as a million men! And she was getting stronger by the moment!
Kelly shifted her arms as the humongous granite slab moved near vertical so
that she was standing upright and holding the entire weight directly above her
head! What a preposterous picture! 2600 feet of solid rock being held aloft by
a three foot tall 7 year old mega girl! As Kelly continued to giggle, she
sounded less strained and began to press the gigantic weight up and down!

"Tee-hee-hee! What does this weigh? 10 million pounds? 50 million pounds? Ha!
It's like NOTHING to me! It would take you men months of digging and
dynamiting to move this much earth and I did it in less than a minute! And now
I'm holding it EASILY above my head and pressing it like it was a small rock!
I am sooooooooo super powerful! I can just keep lifting bigger and bigger
things and just keep getting super stronger and super mega stronger!"

Kelly soon dropped one arm down, holding the 50 million pound weight with just
one arm! Still giggling she tossed the incredible weight up in the air and it
sailed 50 feet forward, crashing back to earth with a gigantic explosion that
knocked me to the ground. The rock cracked into many pieces and fell in and
around the original hole. Dust pushed its way toward me and I shielded my
eyes. And through it all, Kelly strutted back toward me with the confidence of
the super girl that she was. She reached me and placed her hands on her hips.
Her muscles bulged with super strength and she smiled above her basketball
sized boobs of power. Every conceivable muscle on her body was rippling with
super human detail, rock solid density and unbelievable massiveness.

"Well, that got my muscles pretty pumped. Want me to flex up my bicep NOW?"

I shook my head and stuttered. "Uh, I don't, uh, well."

Kelly snickered. "Sure you do! If I had enough power to flex up my pecs 100
feet high BEFORE I lifted that huge rock, just IMAGINE how much super girl
muscle power I have NOW! I can feel the super power surge around my body,
penetrating my muscles, making me feel stronger than ever! My mighty Kelly
muscles are twitching, just waiting to be flexed! Let's get this party
started!"

Reaching her arm out she tensed her fist and her arm solidified back into a
devastating array of muscles fiber and small veins. With just the start of a
flex her bicep soared up to 50 inches around! Smiling down at me she
sssssssssslowly brought her forearm up, causing her massive bicep to form into
a watermelon sized mass of young girl super muscle, now easily 100 inches
around! As she brought her forearm up further, she finally smacked it into her
growing young girl bicep wall and snickered.

"Mmmmmmmmm. This feels so good! My bicep is nearly 120 inches around and 4
feet tall! My bicep is already taller than me and I haven't even begun to flex
hard yet! Time to let loose! Are you ready for this big brother? Think you can
handle this much raw young girl power? And to think you didn't believe I could
even lift 20 pounds, or flex my biceps bigger than 4 inches. Looks like you
were wrong! It's time to show you just how big and powerful your little sister
really is!"

And with an ever so subtle twitch of her wrist, Kelly blasted nuclear power
into her bicep and it started to grow upward at an alarming rate! Her bicep
was quickly 150 inches around, then 200 inches around, then 300 inches around,
then 500 inches around, then 800 inches around, then 1200 inches around! 100
FEET AROUND! 50 FEET HIGH! She had pushed her bicep to impossible heights in
moments! Her humongous muscles pulsed and shined. Thin veins lightly pushed to
the surface. Her beautiful dark hair tingled around her head and around her
massive shoulders. Her dark eyes sparkled. And with a wink, Kelly redoubled
her efforts and stiffened a bit as even more power pored into her body. Her
chest pulsed bigger with every breath, pushing out over two feet in front of
her! Her body tingled and her breath quickened. No one on earth had anywhere
near the amount of power flowing through my 7 year old sister. Kelly laughed
in her glory.

"Ha-ha-ha! This is great! I'm pulling even more power into my super bicep!
You're watching the birth of Kelly the Powerful! The mightiest girl in the
universe! Soon ALL will bow down to me! Now watch as my muscles grow even
BIGGER! When I'm done, Daddy will wish he had never pushed ME around!"

Her bicep was 1400 inches around from her next flex! Kelly's bicep continued
to pulse and surge like an erupting volcano of pure young girl might. And with
her seemingly unlimited power came unlimited muscle size! Her bicep was
quickly 1800 inches around, then 2200 inches around, then 2800 inches around,
and incredibly her bicep continued to grow until it was 3600 inches around!
300 feet around! 150 feet high! Taller than the 100 foot tall pectorals she
had flexed only minutes before! My breath grew short at the sight! Kelly
continued to laugh.

"He-he-he! My muscles are 100 times as big as the biggest bodybuilder! And I'm
not done yet! My power is beyond superhuman, beyond anything in the GALAXY!
And I can FEEL even MORE power crashing in! I'm flexing for the sky!"

And unbelievably, her biceps grew even bigger! And even faster! 500 inches
bigger with each flex! 40 feet in circumference! 20 feet in height every time
she flicked her wrist! Her bicep skyrocketed upward to 4000 inches around,
then 4500 inches around, then 5000 inches around, to 5500 inches around, and
on to 6000 inches around! 500 feet around! Her peak was growing out of sight
as her bicep was now 250 feet high!

Kelly glanced up at her Herculean peak and back down at me. "Just LOOK at my
bicep, big brother, it's as tall as a 20 story building! How strong do you
think my mighty bicep is? I'll bet I could curl an entire MOUNTAIN! HA! Nobody
on this PLANET can challenge me now!"

I let out a sigh, these super muscular displays were driving me near
exhaustion. All of the power channeled into this young supergirl was more than
I could handle. I wanted her to stop, but knew there was nothing I could do.
Kelly was in complete control now! And Kelly wasn't done yet! Her face lit up
and she started to giggle again as her muscles took a quantum shift in
strength and hardness. Kelly looked over her massive, three foot thick chest
and down at me.

"WOWIE! I can FEEL ultimate power flow through my Kelly biceps as I continue
to flex then even BIGGER! My bicep still has PLENTY of room to grow! I'm going
to flex my arm as big as a SKYSCRAPER! AS BIG AS A MOUNTAIN! HA-HA-HA!
BIGGER!"

I looked on with stunned disbelief as Kelly's bicep grew once again! Her
spectacular arm quickly climbed to 6500 inches around, then 7000 inches
around, then 8000 inches around, 9000 inches around, 10,000 inches around. Oh
my GOD! Her bicep was bigger than the Statue of Liberty! Kelly moaned with
delight as primordial power flooded throughout her body and surged directly
into the biceps of this previously frail, little 3 foot tall, 7 year old girl!
How long could this continue? Kelly's biceps were over 400 feet tall and still
growing! They continued their impossible climb as they reached 11,000 inches
around, 12,000 inches around! 1000 feet around! 500 feet tall! Kelly was drunk
with power, overcome with nearly uncontrollable energy! She continued to laugh
as her bicep pushed up to 13,000 inches around, then 14,000 inches around, up
to 15,000 inches around!

Kelly yelled out. "More! More! MORE! YEAHHHHHHH!" Raw elemental power blasted
into her monumental biceps pushing them higher and harder. Her gargantuan
biceps blew up to 16,000 inches around, to 18,000 inches around to 20,000
inches around! 2,000 inches in circumference with every flex! 152 mind blowing
feet around every time she flexed her muscles! Kelly was adding 76 feet in
height to her bicep every second! Her super bicep was 760 feet tall and
GROWING! Kelly continued to giggle and groan with delight!

"And to think that you thought YOUR bicep was big! My bicep is over one
THOUSAND times bigger! And I'm not done YET! This is what true power is all
about! This is what unlimited strength and muscle size REALLY IS! And this is
just my first day lifting weights! My first day flexing! And I can STILL flex
my bicep bigger!"

I could feel the blood rush out of my head trying to keep up with Kelly's
display. I could no longer even conceive her bicep getting any bigger, yet it
continued to soar upward with seemingly uncontrolled limits! Every flex pushed
her bicep higher than two football fields! Her bicep soared up to 22,000
inches around, then quickly on to 24,000 inches around! But even that wasn't
big enough! Or fast enough! Every flex was now so big and so powerful that it
was accompanied by a sonic boom!

BOOM! Her bicep was now 27,000 inches around and 1125 feet high!

KA-BOOM! Her bicep was over 31,000 inches high and nearly 1300 feet high!

KROOOOOM! Her bicep detonated with the power of an atomic bomb to 36,000
inches around! THREE THOUSAND FEET in circumference! ONE THOUSAND-FIVE HUNDRED
FEET HIGH! Her bicep was now taller than the Sears Tower! It was bigger than
anything I had ever seen! Kelly stopped her flexing, tilted her head back to
search for her bicep peak and then looked back down at her shrinking brother!

"Check out THIS bicep big brother! No man made machine has anywhere NEAR this
amount of power. There's no BUILDING on earth taller than my mighty Kelly
bicep! I'm the strongest there is! My muscles are the biggest thing on EARTH!
I'M SUPER ULTRA MEGA KELLY THE POWERFUL!"

Kelly must have sensed that I was at the end, ready to pass out, because she
gave me another smile, giggled and released her ultimate flex. I took in deep
breaths as her bicep reduced in size until it was back to the size of a
basketball. She then trotted over to me and with a quick tug helped me back to
my feet.

"Well, big brother, it looks like you've had enough for one day."

I ran my hand over my face, trying to will some feeling into my head. Kelly
grabbed my hand and I was reminded once again that she was still only a seven
year old girl. My hand was bigger, but her grip was firm.

"Come on David, let's head home. After all, I wouldn't want to lift TOO much
on my first day!"

My jaw dropped as I was about to say something, but Kelly tugged me forward
toward home, giggling the entire time.

The End.
