Super Sister
by K.Malone



Sarah and I usually got along pretty well. We were well behaved kids and being
the only two kids in our family, often times we only had each other. Now, this
meant that although we had each other to play with, we also had each other to
fight with. I obviously always had the advantage when our childish quarells
got physical and this was attributed to the fact that I was older than her by
3 years and was physically bigger and stronger. I wasn't really the athlectic
type, but then no one in the family really was. Sarah and I usually stuck
around the house and entertained ourselves that way. Sometimes we would get on
each others nerves being stuck inside the house on days where we couldn't even
leave the house due to the weather. The fights didn't usually get to rough
when they did occur, but sometimes we had short fuses.

Why were fighting over our favorite chair in the rec room is beyond me, I
don't think it could have been that good of a reason, and I had I known what I
was about to be pitt against, I definately would have dropped right away.

At the time I was 13 and Sarah was 10. There was nothing really that great on
TV, the weather was terrible and we were in bad moods, so a fight was just
waiting to happen. I took Sarah's spot while she got up to go to the washroom,
and not only that put I decided to change the channel and basically take
ownership over the room that my sister was enjoying accupancy of.

" Hey! I was sitting there!" she called as she walked out of the washroom.

"Well, it's best not to get to attached to these sort of things. You need to
learn to let go and move on." I said jokingly. I was being funny about the
situation but I knew damn well that I wasn't gonna give her her spot back.

"I'm gonna move something alright." She replied as she advanced on me.

I prepared for her offensive, knowing full well I had and advantage over my
little sister. I out weighed her by 35 lbs and was 5' 6" against her 4'10". As
she grabed me though, I was a taken by surprise at how much force she had in
her body. I underestimated her strength and ended up on the floor, while she
reclaimed her spot.

I knew this wouldn't do, so I grabbed her legs with both my arms pulling her
onto the floor with me. We both sprung to our feet and started wrestling. I
thought for sure I would have the advantage but I would soon find out that I
was wrong. Our arms were locked and we each poured on all out strenght. We
were evenly matched.

I was evenly matched with a girl whom I had an advantege of 8", 35lbs and 3
years over...or so I thought. Sarah, gave the extra push of effort and sent me
flying back a couple of feet. I was completely shocked.

"Looks like you underestimated the power of your baby sister, John" she said
confidently as she strode to reclaim her seat.

In a flash of anger, I charged and then lept to tackle her before she could
make it to the seat. I was so frustrated with how much trouble I was having
taking down my little sister that I was trying to hurt her at this point, not
thinking clearly.

To my surprise and amazement, I only slowed her down. She was still walking to
her seat with me on her back, she was now just walking slightly hunched over
but still standing and making her way across to her seat. I couldn't belive
it. She was still moving. As I was somehow on her back I wrapped both my arms
around her neck and tried chocking her, and leaning back to pull her on to the
floor.

This just made her mad.

She stopped in her tracks and straightended her back as best she could with me
on top of her. As she straightened up I could feel her grow, her back was
expanding, getting harder. Her shoulders were swelling up and her whole body
was inflating with muscle. I could hear and feel the fabric of her clothes
tearing as I continued to hold on to her neck, which was getting thicker and
thicker.

Sarah reached behind her, and grabbed me by my shirt. Still not sure herself
as to what was going on, she grabbed me with one hand on my neck and the other
grabbing one of my legs. She straightened her arms and then hoisted me
effortlessly over head as she continued to grow. Her clothes were shredding
away and her muscles continued to grow and expand and swell. Her hand fit all
the way around my neck, and soon she realized what was happening.

She looked up and saw the look of terror upon my face as she continued to
grow. She realized she was growing into a huge amazon goddess and that she was
effortlessly holding her older brother above her own head like he was nothing,
perfectly prepared to smash him into to the ground and kill him.

Frightened by what she was prepared to do and by what was happening to her
body, she brought me down to her chest and held me tightly. We hugged each
other as her clothes continued to shred away and her body continued to grow to
gigantic proportions.

Her shoulders were as big as basketballs, her biceps were bigger than
watermelons. Her arms and chest that held me closely were rock hard, bare
skinned and dripping with sweat. I had came in my pants during the
transformation. How this happened in my sheer terror was beyond me.

Sarah set me down on the ground as we tried to understand what had just
happened. I took a step back and just the sight of her in full view made me
cum again. I know it was my sister, but she was also the sexiest, most god
like thing I had ever seen in my life.

Her transformation had rendered her to be almost completely nude except for
her white panties which were just about stretched to their limit, unable to
cover her whole ass.

I stood up to her, eye level with her belly button. She completely dwarfed me.
My whole body was slimmer than one of her huge muscular legs. I looked up to
see her angelic face, her blonde hair still in pig tails. Her face still had
an innocence about it, but she now looked as though she was a woman of 25. Her
beautiful green eyes stared her new body up and down. Examining each limb as
she flexed and felt each massive muscle.

My hands even began to explore her massive body, without even thinking of it.
I soon caught myself, and as my erection poked Sarah's massive leg. She looked
down at me and smiled.

"Go get the measuring tape." she said. Her voice was deeper. It was a sexy
kind of deep voice, like Morgan Fairchild. I scurried as quickly as I could to
obey my little sister. I ran back as fast as I could, still with a raging
errection. She scouped me up with one arm and brought me up to her chest
again.On top her massive steel slab pecks her massive breasts were the size of
beach balls, firm and round. My hands sweated profussely as I grabbed hold of
one of her massive breasts.

"Watch it now" she said as she pulled me away from her massive breast and held
me with one hand, her hand cupping my ass. "Measure one of my biceps." And
with that she flexed her right bicep. It was like a Zepplin. It was huge. I
struggled to get my arm around it. I read the measurement "45 inches" I said.
Measured her massive shoulder span, "4 feet" I cried in disbeliefe.

I soon measured her height. An amazing 7'3".

"Well, let's see how strong I've gotten". Sarah said with a smile as she bent
down to pick me up agian like a rag doll and carry me somewhere where we can
test her strenght.

I didn't know what had just happened, how it happened or what was about to
happen next, but I was excited to find out.
