Big Kelly

Little sister becomes huge bodybuilder.


*Warning* this is a work of pornography. So, go away, little boy!

I couldn't believe that my youngest sister had demolished my older sister, her
boyfriend, and myself so handily. Her body was really huge, and I had to
admit, pretty sexy. Shortly after this incident, Kelly would not come home
after school until late every day. I would have been more worried, but it was
obvious that Kelly could handle herself. Then we got a call from the school
principal's office. Apparently Kelly had been showing up for gym, which was
her first period class, then going awol the rest of the day.

Although Sonja and I were intimidated by our younger sister, we decided to
present a united front. After all, mom had left us in charge of her, and we
should try to behave like responsible adults.

That night, shortly after Leno had started his monologue, the front door
opened. I got up and prepared to face the worst, when I heard Kelly laugh and
say, "That was great! I wish the gym stayed open all night!"

Who the hell was she talking to? I turned the corner and had my answer.
Standing in the hall was the biggest young man I had ever seen. He looked to
be Kelly's age, but was built like a Mr. Olympia. They were both naked, except
for a tiny speedo on him, and a micro bikini top, and stretchy cotton shorts
on her. The shorts were stretched tight over her enormous upper thighs. I came
up short, and stood looking dumbfounded.

"You must be Mike," said the young man very politely, and extending his hand
to me.

"Uh huh," I said stupidly.

"I'm Aaron." I shook his hand. I looked over to Kelly, she had a big,
shit-eating grin on her face. "And you must be Sonja," he released my grip and
reached past me to shake my other sister's hand, she too looked dazed. I got a
close up look at the boy's massive chest. He looked like he could bench press
a car. Kelly had obviously grown, too. Her five foot four inches" body was
thick with muscle. Her arms looked bigger than 15" around, and she was
unflexed.

She grabbed Aaron by the arm and led him to the door to the basement. "This is
my crappy little home gym, but it will have to do." She turned on the lights
for him. "You go down and get started, I'll make us some protein shakes."

Aaron headed down the stairs, and Kelly to the kitchen. "You guys are up
awfully late," she said casually over her shoulder.

"What do we do?" whispered Sonja.

"C'mon, let's both go to the kitchen," I said mustering my courage.

"Um, Kelly, could, um we, talk, uh talk about something?" I winced inwardly
knowing how pathetic that sounded. Sonja was looking at me angrily. Jeez, I
thought, let her confront her mighty-mite sister.

"Sure, what is it?" she said in a sighing with exasperation.

"Well, uh, we got a call..."

"Let me guess: from Principal Morton."

"Yeah, someone in his office."

"I'm dropping out anyway. I'm taking the early exit exam next month. I've
already got a couple of books, it looks really easy." She was still giving me
that condescending, breezy tone of voice, and paying more attention to her
protein shake preparation. She stopped, looked at me, and then at her sister.
She put her hands on her hips, and flexed her upper body. Her enormous chest
and arms swelled, pushing her nipples hard against the little triangles of her
top. Her breasts probably would have been decently large on a girl her size,
but as it were, they were just smooth round pads on top of her massive pecs.
Her lats and biceps actually touched each other. Her mid section was so tight,
it looked bullet proof. "I'm going to concentrate on my body.

"Besides," she relaxed her body and changed her tone to a more serious one,
"I'm actually learning a lot about physiology, nutrition, and even organic
chemistry."

"Kell!" Sonja nearly shouted, "don't be a fool, stay in school!"

Kelly looked at her sister with such disdain. "Look," she said cooly, "I'm not
angry at you guys anymore, but don't try to stop me again, or I will be." With
that, she hit the "puree" button on the blender, effectively cutting off any
comeback. Not that there was one to have. Except...

When she stopped the blender, I said "What about mom?"

"Awww, are you going to be a tattle-tale, and tell on me?"

"What do you think she's going to say about this?"

"Wait here a minute," said Kelly, and walked out of the kitchen. I heard her
go up to her bedroom, turn on her computer and print something. She came back
with a piece of paper in her hand.

Honey, you know that I support whatever will make you happy. You've

been very up-front with me about what you are doing. I am worried,

don't get me wrong. But, I want you to know that I have confidence

in my little girl's intelligence and strength.

Love, Mom :)

I read it twice. Sonja had a defeated look on her face. "Wait," I said,
finding what I thought was one last opening, "did you tell her about the
steroids? And what about your friend downstairs?"

Kelly's demeanor turned frosty. "I told mom I was taking supplements, that's
one of the things she's worried about. But, I've done a lot of research on it,
and I believe I can do this safely. Also, mom let Sonja have a boyfriend when
she was sixteen, and you can have one too (if you could get one)."

Ouch.

"Now," continued Kelly, "I think I've proven that I'm smarter and stronger
than both of you put together. Like I said earlier, don't try to stop me
again." She walked out of the kitchen carrying two extra large protein drinks,
and leaving a mess on the sink. I was scowling.

After the basement door slammed Sonja turned to me and said, "Did you see how
well hung that guy was?"

"Shut up!"

Kelly and her boyfriend worked out (if that's what they were really doing
[shudder]) late into the night. She had the stereo cranked, and the heavy bass
notes made the windows rattle. I clamped the pillow over my head hoping to
catch some sleep, but I couldn't. I kept thinking about going down to reason
with my sister but I was afraid to face her right now. It felt really weird
having the tables turned by my younger sister. What was disturbing was that I
thought she was sexy. I knew they were having sex. If I walked down there
right now, would I catch them having sex? I tried to rationalize: If Kelly's
boyfriend was bigger than her, then I could be bigger than her too, if I took
those stupid drugs.

Then I made the mistake of my life. I couldn't sleep, so I went to spy on my
sister. I slowly and silently snuck down to the basement, got down near the
floor, and peeked around the corner. Kelly and her boyfriend had music blaring
on the boom box loud enough to drown out any noise I might be making. Kelly
was performing bicep curls with 80 pound weights, and Aaron was dirty-dancing
around her, worshiping her body. Both still had their cloths (what little
there was) on, but Aaron's huge erection was stretching his tiny speedo to the
breaking point. They were both breathing hard and sweat was running down their
muscular bodies. Kelly began to do squats. I watched mesmerized, fascinated.
Aaron slid her shorts and panties down, and Kelly paused long enough for him
to pull them over her sneakers. Then he put his head between her legs from
behind, and wrapped his arms around her thighs. Kelly moaned loud enough to be
heard over the music as he slid his tongue into her pussy. At about eighty
squats, Kelly's legs started to shake, at ninety five, as she came up out of
her squat, she shouted, "I.. I'm growing!" He let go of her legs and stood up
just as she lost control and started to fall. He caught her in his arms. His
face was red from the beating it recieved between her thighs, but he didn't
seem to mind. We both stared at her legs, which were growing before our very
eyes. Kelly continued to writhe and shake with pleasure, and Aaron's big
erection finally ripped the speedo from his body, and hung there, draped over
the tip of his member. My own stiffy was begging to be set free from my pants.
I leaned away from the door and unzipped my pants.

As her shaking subsided, Aaron laid Kelly gently on the floor. They kissed for
a while, until Kelly said something I couldn't hear. He looked at her amazed.
She stood up, and he handed her shorts to her. She put them on without her
panties. As she was pulling them up, there was a pause between songs, and I
could clearly hear them rip a little. Kelly smiled as she stood up on her toes
and flexed her legs hard. Her shorts ripped along the seams on the sides as
they rode up her amazingly hard ass. She then wrapped the waist-band around
her fist and tore the shorts from her power-packed body. A white bead of cum
appeared on the tip of Aaron's member. Kelly bent over and licked it off. He
let out a loud "oohh".

She wrapped her legs around his torso, and lowered herself over his member.
They both gasped as he penetrated. Then I saw the most amazing feat of erotic
strength I could ever even imagine. She reached up and grabbed the chinning
bar, lifting them both in the air. He wrapped his arms around the middle of
her back. She began doing chins, while moving him in and out with her legs.
Kelly's chest swelled so large that her bikini top was snapped off her body.
She performed eighteen reps, her arms and chest expanding with each lift.
Suddenly, they both started to shake and lots of fluid began dripping onto the
mat below them. Kelly let go of the bar and Aaron at the same time, he landed
flat on his back, and she landed on top, straddling his midsection with her
knees. She assumed a huge double biceps pose. Displaying muscle mass that was
beginning to rival his.

That's when I shot my own load into my underpants. I came so hard that I lost
muscle control, and fell into the doorway. Kelly was now laying across Aaron's
chest, and they both turned to look at me. I could tell by Kelly's eyes that I
would be lucky to be heard from again.
