------------------------------------------------
Hi there, my name is Cassandra, but most people either call me
Cass or Cassie. At the time that this occurred I was 25 years old
and had just finished my Master's degree in Geography. I know,
it's a pretty boring topic, but I'd always enjoyed it. However,
it wasn't exactly a marketable degree and the economy wasn't
doing very well ... actually, it was horrible. With no job, and
dwindling money, I had to suck up my pride and ask my parents if
I could move back in until I found one. Of course they said yes.
While they had always advised me to pick a more useful major,
they weren't about to turn me out, which was nice of them. But as
is the case with my parents, there was usually an ulterior
motive, and that of course was that I would have the good fortune
(note the sarcasm) of babysitting my little brother. I suppose I
should offer a little history of my family before I go on.

I was born to two 20-year olds in the middle of college. They,
like me, turned to their parents for help who were nice enough to
help raise me while they finished their educations. Even still,
growing up my family was far from financially secure. We weren't
poor by any means, and I never really wanted for anything, but I
did have to work if I wanted the latest clothes or anything like
that. When I was eleven, however, my parents had a second child,
my little brother Charlie. Unlike me, Charlie came into our
family when my parents were well secured in their careers. He got
the latest video games, new TV's, the best clothes, etc, etc ...
This behavior of course spoiled him from a very early age. "No"
didn't exist in my parents' vocabulary when talking to Charlie.
Thankfully, he was too young to be too terrible when I was still
at home and I'd left for college by the time he was really
reaching his "full potential." I did of course see him on the
holidays and that was enough for me. If he wanted to go to a
movie, it was my responsibility to take him. If he wanted
whatever I was using, I had to give it to him. If he needed
something from the mall, I had to go get it for him. But, that's
the price you pay when your parents are paying for your college
education.

So, there I was, going home to babysit my brother so that my
parents could go on another month and a half 'business trip' to
Europe. To describe myself, I'm 5'8" tall, 114 lbs, with dark
brown eyes, a cute, oval shaped face, a disarming smile, long,
straight dark brown hair that comes just past my shoulders, and a
pair of 36C breasts. Sorry if that sounded a little conceited,
but I hate trying to describe myself so I had a friend describe
myself to me. If I had to pick my best asset, I'd probably say
it's my butt. It's not too big, a not too small either ... to me
it's just perfect. Of course, I'm very proud of my breasts as
well, but I've always worked hard to stay in decent shape. Not
that I'm some fitness model or anything, but I've done pretty
well. Charlie and I shared few similarities though. At 14 years
old he was short for his age, only standing at 5'1" tall and
weighing about 140 lbs. He was cute in a boyish way with short,
dark brown hair and dark brown eyes like mine. He didn't smile as
often as I did though and usually just seemed to scowl.

By the time I got home that first evening mom and dad had already
left. Charlie was in the living room watching TV and barely even
acknowledged that I had walked in the door, which honestly was
probably better for me. At least he wasn't demanding that I go
and get him something from in town (we lived in the country by
the way). I walked upstairs and dropped my bags and then went to
the kitchen to make something to eat. I offered to make Charlie
something as well, but he just grunted and kept watching the
television. As I sat down to eat my sandwich, I made a
half-hearted effort at conversation, despite the futility of it.

"So ... only few days left of school. Excited for the summer?" I
asked.

He shrugged, not looking away from the TV, "Sure, I guess."

I figured it was a hopeless attempt and didn't really care to
keep trying. It was already late, so I cleaned my plate and told
him good night. He might have said good night back, but I was
more concerned with going to sleep, not making useless attempts
at drawing words out of my little brother.

The next day I woke up and drove Charlie to school. As was usual,
he was in charge. First, he didn't like the music on the radio,
so we had to listen to his favorite station. Then he wanted to
stop and get a snack at a gas station before school, but not any
gas station ... the one he wanted, on the other side of town. We
finally reached the school's drop off zone and I was already
ready to be rid of him for a few hours.

"Have a good day," I said, trying to hide the sarcasm in my
voice.

"Just be here at 3:15 ... I hate having to wait, and I'm not
going to ride the stupid bus if you're at home." He said before
closing the door.

I nearly growled as I drove away ... another six weeks of this
was going to push me to my last nerve. Unfortunately for me, the
next few days were exactly like that. I could have told him "no,"
or to simply fuck off, but then he would have called to cry to
mom and dad, who would have told me to do as he asked. It's not
that they liked him more than me, it's just that they seemed to
expect more out of me. Being an adult really sucked at times like
that.

However, that Friday everything changed. As usual, Charlie had
been an insolent little twerp all day. I'd suffered through it,
dreading the fact that he was now out of school and would be my
problem 24/7. I'd taken a shower and then gone to get dressed for
bed before taking my laundry downstairs and putting it in the
wash. I was on my way back to my room when I remembered that I
was going to tell Charlie that I was going to the mall tomorrow
and offer for him to come along if he wanted.

I stopped at his door and was turning the knob when I felt a
slight resistance, then a click, as if it had almost been locked,
but not enough to stop the knob from turning. I hadn't had the
time to realize what that meant until I pushed the door opening
and was just about to say something when I suddenly stopped in my
tracks. I immediately realized why he'd tried to lock the door.
He was standing at the foot of his bed, facing away from me with
his shorts around his knees. He was facing his laptop, and from
the stroking movement of his arm it was obvious that he was
masturbating. Several thoughts shot through my mind as I started
to turn away, trying to apologize. But what caused me to stop,
was the glimpse of the image I'd seen on his computer screen. It
looked ... familiar, and suddenly I realized why. I turned back
as he was struggling to recover from being caught, literally,
with his pants down.

"Fuck, Cassie! GET OUT!" He screamed as he dropped the object
that was in his hand and reached forward to try and close his
laptop while he tried to pull his shorts up with the other. As he
finally managed to pull them up, I was already rapidly crossing
the short distance to his bed, my temper rising. He hadn't
managed to close his laptop all of the way and as I flipped it
open again, the image on the screen was exactly what I'd thought.
It was a picture of me in just my bikini on a beach in Mexico
that I'd posted on Facebook; the object that he'd had in his
hand, which was now laying on his bed, were the pair of panties
I'd been wearing the day before. I whirled on him and could see
the look of fear in his eyes.

"YOU LITTLE PSYCHOPATH! YOU WERE MASTURBATING TO ME?! YOUR OWN
SISTER!!!" I screamed. I'd posted the photo on Facebook, and it
wasn't too revealing, but for him to be masturbating to it...

His face was pale and he was backing up, "Please. I'm sorry,
Cass! I ... I ... its not what you think..."

"Not what I think?! So you weren't jerking off to my picture?
WITH MY UNDERWEAR?!"

I could see him searching for words, trying to think of something
to say. He must have started have a dozen sentences before
finally just pleading; "Please don't tell mom and dad! I'll do
anything! Anything! Please Cassie!"

I listened, but I wasn't caring. This seemed just like something
he would do, but I finally had him. I finally had something to
make mom and dad see that he was a spoiled, sick little brat.

"Forget it," I said as I turned and started to walk out of the
room. "Tomorrow, I'm calling them and letting them know exactly
what sort of a disgusting little pervert you are." I walked down
the hall and into my room before slamming the door. My pulse was
still racing, and the anger was seething inside of me. To be
honest, I really had no idea why. I guess it was a culmination of
having to put up with his spoiled behavior for so long mixed with
the feeling of violation that one would feel in knowing that a
family member was thinking about them in such a way, and using my
own underwear none the less! I seriously considered calling our
parents right then, but I knew it would be around 3 in the
morning where they were, and I knew it could wait. I was still
remembering every detail of what had happened when I heard a
knock at my door.

"What?!" I asked, nearly growling.

"It's Charlie..." I heard him say feebly on the other side of the
door, " ... I know you're angry, and I guess you should be. I
know you're going to call mom and dad tomorrow to tell them, but
I ... well, I just wanted to say why I was doing it Cassie."

I was about to tell him to just shut up and go away, but I held
my tongue and he took the silence as a go-ahead to explain. It
couldn't hurt, I thought.

"I know I'm a brat ... and I've always been mean to you, but
you're actually the one person in this family that I like. I
mean, mom and dad seem nice to you I'm sure, and they are, but
they're never around. The only reason they give me everything is
to make up for the fact that they're always gone. I stopped
playing soccer because they'd never take me to practice. They
weren't even home for my birthday last month; they'd gone to the
mountains and left me with a babysitter. I guess I'm sort of a
jerk at school too because..." he paused for a moment, "they make
fun of me because of how short I am. I don't really have many
friends and ... well, then there's you. You've always been the
one person that's nice to me, and I've wanted to be nice back but
I ... I just ... I don't know..." I heard him sigh on the other
side of the door and pause for a few minutes. "Anyway, that's all
I had to say. And I'm sorry again. I understand if you tell mom
and dad ... goodnight Cassie."

On my side of the door I was speechless. At first I'd thought he
might just be trying to take advantage of my typically forgiving
nature, but the more he talked, the more I realized that there
had to be some truth to it. I'd never noticed it before, but mom
and dad never really did seem to be around for him. They'd never
traveled this much when I was in school and they always took me
with them when they did. But they never took Charlie anywhere. I
felt even worse when he mentioned his birthday as I'd completely
forgotten to call him to even wish him a happy one. I'd just
assumed mom and dad would be with him, but in fact he'd been all
alone. I heard him walking down the hallway and instantly felt
myself being torn back and forth. Yes, what he did was disgusting
and wrong, but ... was it really? It wasn't like he'd raped me or
anything. I already felt terrible that I'd completely ignored my
brother on his birthday, so how much worse would I feel if I told
on him to mom and dad; undoubtedly getting him grounded and
humiliating him beyond imagination. I laid down and tried to get
some sleep, but the question kept running through my mind along
with the image of him, his shorts around his ankles and his
small, pale butt facing me while he masturbated with my panties.
Finally, after an hour, I knew my answer. Anything that caused my
conscience to be weighing on me this much wasn't something I
could do. Once I'd finally made this realization and settled on
my plan for the morning I was asleep before I knew it.

The next morning I woke up early as usual and went downstairs to
make breakfast for the two of us. The smell of cooking always had
a way of waking my brother up and sure enough it wasn't fifteen
minutes before I saw him sheepishly come into the room.

"Hi Cass," he said, still wearing his pajama bottoms and a
t-shirt, "what did mom and dad say?"

I looked over, hiding my smile. I knew it was wrong to torture
him like this and couldn't do it for long. I walked over and slid
a couple of pancakes onto his plate which already had bacon and
eggs.

"They didn't say anything ... because I didn't call them."

He looked at me strange as he sat down, obviously hoping for the
best, but not wanting to get his hopes up. "Y-you didn't call
them? Why?"

I sat the pan back on the stove and turned to him, "Well, because
that would have been a really mean thing for me to do. I should
probably apologize to you, Charlie. I hadn't even noticed how
detached mom and dad have been from your life ... I just always
assumed you were spoiled in every way."

I could see his spirits almost instantly rise as he searched for
words ... suddenly he jumped up and walked over, hugging me
tightly. I knew he'd be relieved, but I was taken aback as he
started to say thank you. Honestly, it was the biggest display of
emotions I'd ever seen from him.

"Thank you thank you thank you! Oh my gosh ... y-you're like the
best sister ever!" He said as he finally released me, obviously
excited. "But you don't have to apologize ... I mean, I knew I
was being a jerk ... I just didn't really ... I don't know, know
how to stop I guess."

I smiled ... for the first time honestly in my life, I actually
started to feel at ease around my brother; like he was someone I
could actually get along with. "Don't worry about it. But let's
let this be a fresh start for us, ok? I've always wished we could
be closer, and now we have six weeks of just the two of us."

He nodded enthusiastically, "Definitely sis! I'd love that. And
... I'm sorry about last night with the whole picture thing," he
said, blushing as he recalled it.

I shrugged, "Don't worry about it. Honestly I think I
over-reacted a little anyway ... I guess it just caught me off
guard, and combined with everything else, I just exploded."

He looked up, a little surprised. "Really?"

I grinned as I walked back to the counter to make my own plate.
"Yeah ... to be honest, it was kind of flattering. How many
sisters can say their little brother masturbated to them?" I
said, half-joking.

Charlie laughed as well as the tension that had existed between
us for years finally dissipated. "Probably more than you'd
think."

For the first time ever we had an actual light-hearted
conversation as we ate. It was great to finally be able to catch
up with him and talk about each other's lives and all that had
been going on. After breakfast I took him to a movie and we just
hung out for the rest of the day. After years of classes and
working, it was great to be able to relax with no immediate
responsibilities.

Over the next few days we developed a pretty regular routine ...
we'd wake up and eat breakfast, then hang out or play video games
(one of my boyfriends in college got me hooked), go to the mall
or a movie, then eat dinner and watch a TV in the living room
together. It was the most fun I'd had in ages. We were closer
than we'd ever been before, and I was loving it. However, one
night there was a slight ... problem. Well, not really a problem,
more like an incident. We'd just finished watching a movie and as
usual I'd taken a shower before going to my room and getting
ready for bed. I'd checked my email and was about to go to sleep
when I realized I'd forgotten to brush my teeth. Climbing out of
bed, I was walking down the hall to the bathroom when Charlie
emerged. I'm obscenely quiet for some reason and he hadn't known
I was in the hall.

When he saw me, he jumped, obviously startled. "Cassie! I
t-thought you'd gone to bed."

He'd tried to slide his hand behind his back without me noticing,
but he failed miserably and although I'd only gotten a glimpse,
it didn't take me more than half a second to recognize the
panties I'd been wearing just an hour before. The recognition and
realization flashed through my mind before he'd even finished his
sentence. The question though, was how was I going to respond? I
paused for perhaps a second or two in deliberation, but that was
all I needed. I'd known he was attracted to me, and that he'd
masturbated to me at least once, but after being caught I'd
assumed he would have stopped. Yet here he was, sneaking back to
his room to use my underwear again. I wasn't mad though.
Surprised, perhaps, but not mad; after all, I'd basically told
him as much a few days before, and to be honest I was loving how
close we'd become, even if he was apparently still attracted to
me sexually.

My eyes had glanced down to where his hand had disappeared behind
his back and as I looked back up, it was obvious he knew he'd
been caught, but to his surprise, and relief, I just smiled,
acting as if nothing was amiss.

"I just forgot to brush my teeth before bed. How about you?"

He stammered for a second, and it was clear that he was still
surprised I wasn't saying anything about the panties he was
obviously hiding behind his back. "Me? I um, was just ...
brushing my teeth too."

"Well sleep tight," I said as I stepped past him into the
bathroom.

"Yeah, you too sis!" He said, recovering from his shock. I heard
him walk down the hall as well as the unmistakable "click" of his
door locking. As I got in bed a few minutes later, I couldn't
help but think about the fact that at that very moment, my own
little brother was stroking himself to me, using the panties I'd
been wearing just an hour ago. I know I should have been
disgusted, or repulsed, or angry, and a week before I would have,
but after becoming so close to him ... seeing this other side, I
felt different. Knowing he didn't really have many friends in
school, and knowing he didn't have a girlfriend, I guess I just
felt glad that I could be his best friend plus the girl he
fantasized about ... the one he masturbated too. And to be
completely honest, it just felt right. Maybe it was my sisterly
instinct, but I wanted to be there for him.

The next morning, I woke up earlier than him as usual and went to
the bathroom. As I brushed my teeth, I glanced at the clothes
hamper and wondered if he'd returned them when he was done.
Walking over, I lifted the lid and sure enough, there was my dark
blue thong that I'd worn the day before. As I reached in and
pulled it out I nearly gasped at the sight of the inside of it. I
knew he must have been cumming if he was masturbating but as I
saw the inner material I couldn't believe how much there was.
Nearly the entire inside was covered in my 14 year old brother's
dried cum. It sent a taboo thrill through me as I stared at it
... the product of my little brother's orgasm as he thought of
me. I heard his door open down the hall and quickly tossed the
thong back in before closing the top.

That day, as we hung out, we both knew something was different.
He knew he'd been caught red-handed again and I'd pretended not
to notice and I now knew my brother was thoroughly infatuated
with me. After he'd bared his soul to me a few days earlier, we'd
become best friends. But after the interaction last night, we
seemed to become even closer physically. I had no idea how far I
was willing to let him go, and he was still too timid after my
explosion the first time to try anything crazy, but the subtle
change was still there. That evening, as we settled in on the
couch to watch a movie together, He sat closer than he usually
did. He was remarkably smooth about it, especially for his age;
plopping down next to me and leaning against my side. I could
have playfully shoved him away as I would have done before, but
that night, I put an arm around him as the movie played. It felt
so right, holding him, and in the dark room I saw him glance at
my chest a few times (he wasn't quite as subtle in those
instances), but I pretended not to notice. As the movie came to
an end, we both stretched.

"I liked that one ... better than that chickflick you picked the
other night." He said, standing.

I laughed as I stood as well, "You only like movies if they have
people getting shot or cars blowing up."

He laughed as well, "Hey, I also like movies with boobs!"

"Ahhh, boobs, huh? Well, maybe tomorrow we'll find one with lots
of topless girls."

"Deal!" He said with a grin. "So, are you going to take a shower
tonight?"

I knew exactly why he was asking. "Yeah, it's been a long day; a
hot shower would feel good. Why, were you going to use the
bathroom?"

He shrugged, "I don't know, probably not. I'll just get one in
the morning."

"Sounds good," I said as I walked over, "Goodnight hug?"

He laughed, remembering the hugs mom used to give him a few years
before. "Well, only for you sis."

At nearly a foot shorter than me, his head was about level with
my breasts, which I knew he would love. "Ohhh, I feel so
special!" I said, wrapping him up and enjoying our playful
banter. I felt him hold me tightly and held him the same. Knowing
that in just a little while he'd be cumming in my panties was
such a thrill for me, and I knew holding me was going to be a
great memory for him when he masturbated. As we finally let each
other go, his hand brushed over my butt and I knew it was
intentional as he looked up at me, not too subtly gauging my
reaction. He knew he was in the clear when I just grinned and
told him goodnight.

The next morning the panties I'd left in the hamper had another
massive load of cum sprayed in the inside. I was quickly learning
to love this morning ritual of seeing my brother's "present" from
the night before. That day was much like the day before as we
hung out and playfully flirted with each other. There was a fine
line that was becoming increasingly blurred. It could be
attributed to us just becoming closer as friends, but he was
slowly becoming bolder, and I was allowing him to get away with a
little more each time. We would find excuses to "wrestle," such
as stealing from each other's plates or changing the channel on
the TV from what the other was watching. Despite the fact that I
was taller, and still stronger, I would sometimes allow him to
get the upper hand and his hands would inevitably slide beneath
my shirt and over my bare stomach. On more than one occasion I
felt his erection in his underwear pressing against me. Anyone
who ever saw any of this would be hard pressed to say anything
inappropriate was actually happening though. Our evenings
continued to change as well. True to my word, we did start to
watch movies with "more boobs," and it just so happened they
usually had a lot of violent action in them that Charlie loved as
well. I loved watching his face when the women would go topless;
to see the look of awe and lust on his face. And of course, our
Goodnight Hugs became a tradition. Each day his hand seemed to
linger a little more on my butt as he let me go.

It had all occurred so smoothly, so continuously, that it wasn't
until the eighth day of our "new relationship" that I realized
just how far we'd gone. We had still yet to do anything
definitively "wrong" but I was letting him rest his hands on my
butt for nearly five seconds each night during our hugs and our
movies were usually rated NC-17. I knew Charlie had surely
watched porn on the internet, but the stuff in the foreign films
we watched included everything imaginable. From blowjobs, to hand
jobs, to penetration sex. Holding him while watching a woman suck
a cock on screen was getting perilously close to going too far.
As I came to that sudden realization, I knew I had a choice to
make. I could either stop things where they were, or let them go
past the "acceptable" point. There was no doubt in my mind that
this was the happiest Charlie had ever been in his life, and I
was loving this summer more than any I'd ever had as well.

My mind was still conflicted a couple of days later when Charlie
asked if we could go swimming in the river. I knew the spot he
was talking about well as dad had used to take me there when he
had more free time. The idea of swimming and laying out in the
warm summer sun was too good to pass up, so I said of course.
Even better, we decided since I hadn't been there for his
birthday the month before, that this could be his 14th
celebration. We packed up some food and drinks for a picnic and
planned to make it an all-afternoon event.

After everything was packed into my SUV, we both went up to our
rooms to get changed. The question of whether to let things go
any farther forward was still lingering in my mind and on top of
that, I desperately wanted to make this celebration special to
make up for having missed his actual birth. However, as I went to
my dresser to look for a swimsuit, an answer to both of my
questions presented itself. On spring break of my senior year my
friends had bought an obscene yellow sling bikini as a prank. It
looked like something out of the 90's and left hardly anything to
the imagination. I'd only kept it for sentimental purposes, but
... it would be a surprise Charlie would never expect. If I wore
the bikini, I'd basically be offering myself to my 14 year old
brother. I stared at it, the possibilities running through my
head, and the taboo thrill of those possibilities was all the
answer I needed. This was going to be the best birthday present
Charlie ever received. I slid it on and looked at myself in the
mirror. The material covering my breasts was just wide enough to
cover the nipples, and the middle V only connected just above my
crotch. The back was almost non-existents and the sling
disappeared between my butt cheeks, leaving nothing to the
imagination. I grinned at myself in the mirror as my pulse raced;
this was the perfect surprise. I slid a pair of denim shorts and
a t-shirt on over the bikini and went downstairs. Charlie was
already waiting with his towel in a pair of small swim trunks and
a t-shirt. Within a few minutes we were loaded into my car and
heading for the river. Our destination was one that few people
knew about. The road that led to it was over private property
that belonged to one of our father's friends which opened up on a
bend in the river. It was only a few feet deep at that point and
in the middle were large flat rocks that you could swim to and
lay on. In the summer sun they felt amazing after a swim in the
cool river.

I parked the vehicle along the water's edge and got out. Charlie
looked over the scene with a smile. "Thanks for taking me, Sis!
This is the best birthday ever!"

I grinned as he took his shirt off, revealing his small, young
chest. "Well, I'm glad you're loving it so far Charlie!"

He had moved down to the water to test the temperature as I
undressed, feeling the sun hitting my almost completely bare back
as I finished removing my shirt & shorts.

"Oh wow, Cass the water feels..." I heard him trail off
mid-sentence and looked up to see him staring at me. " ... WOW! I
mean, um ... nice bikini, sis..." He said, still openly staring.

I grinned. It was the exact reaction I'd been hoping for, and to
see his hungry eyes on me like that caused my heart to flutter.
"You like it?" I said as I walked down next to him.

He was openly staring and trying not to stutter, "Y-yeah, I mean,
it's um ... it's awesome!"

"Well that's good, because I wore it just for you. I know I
wasn't there for your birthday, so this is my way of making up
for it."

His eyes were still roaming over my body and as I walked down to
the edge to dip my toes in the water I could hear him gasp as he
saw my practically bare ass. "Y-You mean ... you wore that ...
for me? You are literally the coolest sister, EVER!"

I grinned over my shoulder. I'd never seen such a hungry, lustful
look in someone's eyes before. "I'm glad you like it then." I
turned back to him and backed into the water. So are you coming
in or what?"

He ran into the water after me as I splashed him and dove into
the deeper part of the river. We were both great swimmers and
were evenly matched in the water despite the height differences
when standing. For nearly 10 minutes we chased and splashed each
other, laughing before I finally swam to the massive flat rock in
the middle of the river. I walked onto it as Charlie splashed out
of the water, trotting up behind me and playfully grabbing me
from behind. "GOTCHA!" He said as we both collapsed forward onto
the warm stone, laughing, with me lying face down on it and him
on top of me.

"Ok, Ok! I surrender!" I said playfully as I lay beneath him.

"Yes! I told you I'm the best!" He said gloating as he learned
up, still straddling my thighs.

I laughed, "Fine, you're the best, now get off of me squirt, I
said, starting to lift myself up, but he still had me thoroughly
pinned. The movement caused my ass to grind against his crotch,
and if the hormones a 14 year old boy weren't enough, the primal
instinct of a man who has a scantily clad woman beneath him
caused his cock to quickly start to harden in the confines of his
swim trunks.

It was a daring move, but I felt him push me down again. He knew
I'd worn this bikini for him, and he knew I'd let him go farther
than either of us could have imagined over the last couple of
weeks as we'd grown closer. "No, you're my prisoner." It was
obvious he was enjoying the positon too much to let me go
willingly.

Hearing him talk like that was incredibly hot as I felt him
hardening against my ass. I realized he was ready to cross the
line ... and so was I. My pulse raced as I looked over my
shoulder up at him. "Well, if you let me up, you'll get your
second birthday present."

He hesitated. He was enjoying feeling my nearly bare ass pressed
against the hard-on in his swim trunks, but the look in my eyes
seemed to promise something better. "What is it?"

"It's a surprise, but I think you'll love it."

He loved where we were at, but the promise of more was too much.
I felt him start to shift as he slid back on to his knees and his
weight lifted off of me. I got to my own knees and turned back
towards him. Even kneeling I was significantly taller than him,
and it just served to remind me that I was still eleven years
older than him. Knowing what I was about to do, it just seemed
right to give my baby brother one last hug before our innocent
relationship ended forever. I leaned forward and wrapped my arms
around him, feeling his young small body in mine.

"I love you so much, Charlie."

He was taken aback, it wasn't what he was expecting, but he held
me tightly too. "I love you too Cassie."

I held him for a few moments longer before finally letting go and
leaning back. He looked at me confused and the hint of
disappointment on his face.

"W-was that my birthday present?"

I smiled and laughed a little, shaking my head. "No, baby brother
... I just wanted to hug you one last time before we did this."

I slowly stood up in front of him and raised my arms to the
slings of my bikini. Watching his face, I saw his eyes go wide as
I slid them off, revealing my 36C breasts topped with quarter
sized, dark nipples. As the bikini fell to my ankles his eyes
went down to my smoothly shaven pussy. He'd seen pussies on TV
and the internet before, but seeing his own sister's in person
had him speechless.

"C-cassie ... you're ... I..." His eyes finally looked up at me
as I bit my lip.

I turned my back to him and got on all fours. With my pussy and
ass presented to him, I looked over my shoulder. "This is your
birthday present, Charlie."

The look on his face was priceless. It was a mix of lust and
gratitude as he let me go and stood up, sliding his trunks off.
He stepped out of them and stood there as we both took in the
sight of each other's bodies. His small penis was standing erect
at maybe four inches. He had a small patch of hair around his
small cock, but I realized how he managed to spray so much cum
into my panties as I saw the two, golf ball sized testicles
hanging beneath my little brother's cock. His eyes were roaming
over my ass and my hairless, glistening wet cunt being offered to
him as he walked up behind me and got down on his knees. I had to
spread my legs wider to lower my cunt to where he could reach it
as he moved into position. I felt his hand running over my ass
and looked over my shoulder at him. The lust on his young face
was so hot and I couldn't help but moan. Like a passenger on a
plane as it accelerated down the runway, I knew there was no
stopping now.

My heart pounded in my chest as I stared into his eyes, "Happy
birthday, Charlie"

He couldn't hold back anymore as I heard him moan too, he
positioned his cock against my soaking wet pussy and paused for
just a moment, "I love you Cassie!" he screamed and then thrust
forward, burying his hard, young cock inside my soaking wet
pussy. His natural instincts kicked in and he gripped my waist,
thrusting forward over and over.

I nearly came right then as I felt my baby brother fucking my
pussy. There was nobody for miles around to hear as I screamed
out in ecstasy. "YESSSSS! FUCK ME CHARLIE! FUCK YOUR SISTER'S
CUNT!"

I started to thrust back, meeting his with my own. The slapping
noise of his hips slamming into my ass seemed so loud in the calm
peacefulness of the outdoors. "Fuck me Charlie! Ohhhh yes! Fuck
my cunt with your hard cock little brother!"

What he lacked in skill or technique he made up for in sheer
determination as his powerful thrusts rammed his small cock into
me again and again. Both of us moaned and gasped as our
relationship entered a region neither of us could have imagined a
month before.

"Yeah! Take my cock Cassie! Your pussy feels so warm & wet! I
want to cum inside you!"

The statement caught me off guard. Of course he'd want to cum
inside me, why wouldn't he, but I hadn't had sex in months and
hadn't been on birth control since Christmas. But how could I
tell my little brother no on his first time?

"MMMM, YOU WANT TO CUM IN YOUR SISTERS WET PUSSY?! FUUUUCK OK, DO
IT CHARLIE! CUM IN MY PUSSY LIKE YOU CUM IN MY PANTIES
EVERYNIGHT!!"

"OH YEAH! OH FUCK SIS I'M ALMOST THERE!! I'M ... ALMOST ...
AGHHHHHHH I-I-I'M CUMMMINGGGGG! I'M CUMMING IN YOU CASSSIE!"

I felt his small cock spraying his potent sperm into my
unprotected pussy. I knew he could be impregnating me at that
very moment, and the thought of my little brother giving me a
baby sent me over the edge as my pussy began to spasm around his
cock. "YESSSSSSSS! OH FUCK CUM IN ME CHARLIE! CUM IN ME LITTLE
BROTHER! YESSSSS YESSSSSS" The orgasm crashed through my body
harder than any I'd ever felt. The feel of my brother's sperm
splashing inside my cunt was too much as my body convulsed.

I felt his thrusts slow and then come to a stop as the orgasms
dissipated from our bodies. He held himself inside me and I felt
his cock twitching a few more times before he finally pulled out
and rested back against his feet. I collapsed to my side and
rolled onto my back, looking at him. He took in the sight of my
tits for the first time, staring over them and my smoothly shaven
pussy with his cum starting to seep out of it. I'd seen the dried
form of the substance many times over the past week, but to see
it fresh and seeping from my cunt was too tempting. I slid a hand
down to it and scooped a handful out. I brought it to my mouth
and gave him a grin before I started to lick his load off of it.
The taste was different than most I'd ever had. The texture was
normal, but it didn't have the saltiness I was used to. Instead,
it was more of a bland taste. If anything, it was better than
most I'd tasted and I enjoyed licking the rest off.

Charlie watched with fascination as I ate his semen, "Wow ...
sis, you like eating that stuff?!"

I grinned and shrugged, "Well, not all the time, but yours tastes
pretty good."

He moved over and sat beside me, his small cock softening to just
an inch, "Really? Thanks! This was the best birthday present
ever, Cass!"

"I'm so glad you liked it, Charlie!" I saw his face fall a
little. "What's the matter?"

He shrugged, "Its just what you said before we ... fucked. I ...
well, I really do love you Cass."

I hesitated for a moment, "I love you too, Charlie. You're my
brother."

He nodded, "I know, but I mean, I'm like in love with you. Like
in those movies you like to watch. I've always felt like that
about you."

I sat up, "I know that Charlie, that's what I meant. I love you
as a brother, but this isn't going to be a one-time thing
sweetheart. This was just the first time."

He looked up, the sad look gone from his face. "REALLY?!"

I laughed and smiled, "Of course. I'm just so happy you feel the
same way!"

He was nearly ecstatic, "I totally do!" He wrapped me in a hug
... the first time we'd ever embraced topless before. The feel of
his bare chest against my large boobs felt so incredible.

We laid back onto the rock, holding each other in the summer sun
as his cum slowly spilled out of my pussy.
