Sisterly Rape

A muscle growth story about a teenage girl who gets raped by her abusive older brother, and then seeks revenge.


*Note- Do to the nature of this story, I think it is prevalent to point out
that the content presented here intended to offend anyone in any way. This is
purely a female muscle growth/sexual fantasy.

Before we start I need to make one thing clear: I am not proud of what I did,
but I sure as hell got what was coming to me in spades. With that said, lets
start at the beginning then; it all started in the summer of my freshman year
in high school, me and a couple of my buddies were starting to notice girls as
sexual objects, rather than disgusting creatures that got in your way when
your trying to play sports. During this time we realized if we wanted to get
in their pants we needed muscles, thus me and 3 of my friends began hitting
the gym sporadically after school. The results were defiantly below average,
(mostly because we did every exercise the wrong way/ ate terribly/ and got
drunk every weekend), but we got what the girls wanted: biceps and abs. For
the most part our plan worked perfectly, we'd show up at the party, flex are
soft 14" guns, take off our shirts, let the girls touch our sloppy 4-pac
belly, then after the show 90% of the babes basically let us fuck their brains
out. In high school, life was good, damn fucking good, I had average grades
but I was in the popular crowd and got laid almost at will.

It was around this time were my sister, Gina, who is 2 years younger than me
was starting to blossom into a women. At 15 as a freshman, just as my sexual
instincts began to erupt I began to notice her in a different light; while the
body wasn't developed yet, her face was always very cute, and by 13 it would
be an insult to say anything other than it was beautiful. Over the course of
the next 3 years her body matured nicely. Her ass got rounder, waist narrowed,
legs became long and shapely, and her tits got fucking huge (38D!). The
changes obviously occurred gradually but given the fact that I was barley
home, her hotness went virtually unnoticed until my graduation party in the
summer before I moved away for college. I was out in the pool as the
festivities were occurring when I heard the screen glass door open from under
the deck, it was my 16 year old sister dressed in a short black mini skirt,
matching heels, and a white blouse that could barley restrain her jugs.
Flashing a picture-perfect smile to family and friends she walked towards me,
with her sexy tanned thighs and calves working as she moved across the grass.
When she gave me a kiss on the cheek I could smell the erotic perfume she wore
while I glared down at her breasts pressing against the side of the pool. By
now I had a full-blown erection that would have been extremely embarrassing
had it not been for the pools water. Small banter occurred between us, all the
while I was simply awe-struck my smoking hot sister, that could even drive
yet!

In the course of the next few days I began spying on her habitually, almost
getting caught several times be her and my parents. "How could I have missed
this?" I thought to myself as I stroked my 5" hard-on while whacking off to a
mental image of my sister; two weeks passed and it got to the point were I'd
get hard just by seeing her at the dinner table! A short time later, I was
laying in bed thinking about my situation, and eventually I thought about what
should be unthinkable: Rape. I knew my sister was a moral girl (Though NOT a
virgin), and would never consider a mutual sexual encounter, so I knew if I
even wanted a piece of her juicy ass I'd had to take it for myself; despite
the fact that my workouts have wavered over time, I knew that I was still far
stronger than a 16 year old girl. Thus, I planned my attack; I decided on the
following Wednesday evening, purely because both of my parents are attending
an overnight convention for my fathers work. That's the easy part. The hard
one was getting my sister to cooperate, well at least enough for me not to get
caught. I considered a variety of ways, slipping her a pill, getting her
drunk, or mounting a visual serious of unflattering evidence on her behalf;
however I soon realized that all of this was unnecessary. I simply decided
that after I was done I'd simply dare her to tell our parents, while
confidently reminding her that I was the favorite child, their first, their
angel, and under no circumstances will they ever believe that I raped my dear,
younger sister. Gina was not fool by any stretch of the imagination, she knew
that what I have said is true, they'd never believe her, and no one will ever
know ... ... .

Wednesday, August 17. A date that I will never forget, the time had come to
complete my sexual fantasy. An hour after my parents were gone I proceed to
Gina's room, peering threw the keyhole I saw her: a golden bronze vixen, with
gelled dark brown hair, a gorgeous face, and sexily curved body wearing only
high cut cotton shorts and a tight top that her big tits stretched further
with every breath she took. I couldn't take it anymore, I was infatuated with
her, I was like a machine with only one goal: Getting between her legs. I
stormed into the room, knocking her off her chair I tossed her onto of her bed
and violently tore her clothes off her ample body, while resisting futile
attempts to defend herself I pinned her down, and stared at her naked figure
and said: "GINA!!!, stop struggling its no use, your to WEAK." (her screams
quickly turned to sobs as she asked me why I was doing this) "Looks like
someone has matured nicely (staring at her 38D tits), ever since I saw you at
the party earlier this summer I knew I had to have a piece of your ass, you've
become stunningly beautiful Gina, and now big brother is going to take you all
for himself" ... ... . For the next hour my condom laden dick ravaged the
teenage vixen as I came time after time until finally I was satisfied, moving
her off the bed, I carefully cleaned all the evidence and then kneeled down to
my weeping sister: (while licking the last remnants of cum off my fingers)
"Ill make this simple, by the time mom and dad come home there will be no way
you can prove any of this happened, (standing up I let out a faint chuckle)
and besides, they'll never believe you, and know one will ever know. The next
week I left for an out-of-state college and wouldn't return for nearly nine
months ... ... ..

(The rest of the tale will be told threw Gina's eyes)

I watched with utter loathe as my piece of fucking shit brother's plan left
the ground. (Thinking to myself) Ever since the terrible events of last week
I've lived in a constant terror, to afraid to confront my parents, and just
not physically strong enough to ... ... wait a second ... that's it, physical
strength! The ultimate revenge, Mom mentioned that the asshole would be gone
until next May, so I could!!....... FUCK! Damn it! A few months won't be
enough time to build big muscles unless I get some extra help.

The following day was the first day of the new school year, and it would be
the perfect opportunity to talk to Kelly "The Hammer" Bringums; she basically
is the biggest girl jock in the school with a reputation for beating up boys
that got in her way (hence the "Hammer") . Kelly used to be just like any
ordinary girl until the summer before the 9th grade; Kelly started pumping
iron with her older brother's weight set in their basement. She made a sudden
jump in size and muscularity; inside fifteen weeks the once scrawny 14 year
old went from 108lbs to a beefy 135. She is now a senior and although her
muscles have not gotten any larger, they have hardened nicely over the years,
producing a nicely sculpted physique. The entire school was convinced she used
the goods, how could she have not? Fixated on her startling transformation, I
told Kelly "The Hammer" about my situation:

Kelly: Oh dear god Gina, that fucking scumbag! If it's any constellation, and
I'm sure its not, I never liked your brother and now I think he should rot in
hell.

Me: Thanks Kelly, but I need more than your condolences ... ...

(cutting me off)

Kelly: Yes, I'd be happy to kick the living shit out of him for you!

Me: Ha! I appreciate the offer but I am going to handle things myself, that is
after you hook me up with the supplements that got you jacked in freshman
year.

Kelly: (smirking) Now that's the response I wanted to hear. The drug is called
Tigress Formula 1, my fathers company, Litheron, developed the first prototype
of TF1 four years ago. It is a female muscle enhancing product that transmutes
your genetic structure into a muscle building machine. And as you can see,
(opening her arms and giving herself a full body look), the results were
unimaginable, to great for open market use; therefore the government banned
the product for general service (threw both backdoor deals and a truckload of
taxpayer dollars) and restricted its usage to military females only. So,
unless you wearing a uniform; TF1 is all but impossible to acquire, but
fortunately for you my father still has an abundance excess left over from my
cycle. I stopped taking TF1 because my size is a perfect combination of speed,
strength, and agility; basically if I got any bigger it would restrict my
movement and hinder my professional sports careers. But for what you plan to
do, I think you want to go to the next level, meet me at my house right after
school, and good luck Gina.

The very next day after school I began my mission in the girl's gym, secluded
behind the locker room, at 2:30 pm it was the perfect place to work out in
solitude, due to all of the sports teams either being away for games, or
practicing at other venues. The instructions for TF1 were simple: Take 1
packet directly before every workout with plenty of water. Just as instructed
I popped in the pills and got to work ... ... ...

-(3 Weeks Later)-

MMarrghhh ... 8 ... .mmmmaarrghhhh ... 9 ... ... mmmmmmmmmaaarrrrrrrrggghhh
... .10! I grunted, with a loud clank I racked the 125 pound loaded bar onto
the bench. I grabbed my popping pec's and hit a crab flex in the mirror,
although their not big yet, there defiantly getting larger and much more
defined. The Tigress formula is working wonderfully; my flat bench has
exploded in a very short period of time, going from 65lbs to 125lbs in 27
days! On every part of my body my muscles are enlarging, and my weight has
increased from 103lbs to 113! Small, but hard biceps, and triceps are now
popping out of my arms; firm shapely thighs and claves are were my skinny legs
used to be; and most impressive of all is my toned midsection, from regular
teenage love handles to a sexy core with emerging abdominals! Need less to
say, I am absolutely in love with my changing body, so much so that after my
daily workouts I always take the time to flex my little pumped muscles in the
locker room mirror. Now I needed more fuel to grow my muscles, so my parents
have noticed a serve change in my eating habits, since I consume nearly
quadruple the calories I previously did. Even the boys at school have noticed
my transforming figure, now in gym class I always put on a tiniest butt
hugging shorts I can find, which only accents my new rounder, fuller, buff
ass! While jogging I hear the boys whistling and yelling phrases such as "YEA
BABY" ... ... .. that might be because with every stride my legs are pumping
up with young, tanned feminine muscle and my muscular butt is ballooning
inside my snug shorts. Everything is going according to plan; I swear now
every day I'm getting bigger and stronger.

COME'ON BICTH, DO YOU WANNA GET BIGGER OR NOT?? Kelly "The Hammer" screamed
from behind me as I banged out rep after rep on the bench loaded with 205lbs
on the bar, after my 14th I let out a moan and racked the weight. I'm up to
141lbs now, (slightly bigger than Kelly!), since I've muscled up, we've become
great friends pushing are exploding muscles in the gym harder than ever
before. After chest we hit biceps, me and Kelly cranked out sets with 45lb
dumbbells swelling are 14" guns to there peaks and beyond, after our final set
we flexed our biceps in all there glory, with each flex we watched as both our
bi's rippled, twitched and rose higher. Finishing off with a couple of huge
double-bicep posses a conversation ensued:

Kelly: Fuck girl, what a workout! (looking at my muscles) God damn ... ..bitch
your fucking DISEAL now! Christ I think your even bigger than me!

Me: HeHe, thanks babe, but I'm not done, I want more lots MORE. I've still got
4 months till the piece of shit comes home and I plan to get huge. (with that
sentence complete I went into a intense crab flex that made my muscles burst
out with definition and size, leaving Kelly only to watch as my skin lost the
battle with my erputing muscles). Seconds after my "flexathon" I relaxed my
muscles, but even in this state my solidly pumped muscles and thick veins
twitched periodically.

Now nearly 6 months have passed since I started using Tigress Formula 1, and I
couldn't be happier with the results; combined with a strict diet and rigorous
training I've bulked up to 167lbs of large cut muscles. Now when I flex in the
gym mirror my reflection shows a 16 year old goddess; with big 16.8" baseball
sized biceps, and 28" tree trunk thighs I enjoy flexing my bugling muscles now
more than ever; watching them twitch and swell larger and larger every day
brings a devilish smile to my face as I know I am not only far stronger than
my asshole brother, but my whole family and most guys as well. In this time,
my life as a whole has drastically changed, my parents are now basically my
slaves; they do as I wish night and day. Men beg to come between my muscular
thighs, and women fear me with a jealous rage when I prance my overly muscular
butt around my new gym with as little spandex as possible. The best part of
all this is that asshole doesn't know of any of the changes, and in two months
time I'm going to get even bigger to fully punish him for the sin he committed
... ...

The End?
