 The end of day bell rang, and I left the classroom, completely unaffected
by what I learned today.  It came to no surprise for me; the grown-ups
liked to overdramatize a lot.  You get into a scuffle, and they treat
bruises and scratches like amputations.

   I followed the normal path home, which was only half a mile walk total,
going from across the street from my school and through the apartment
complex's side gate to the other end, where I live on the first floor.  By
the time I got to the crosswalk, the guard was already leaving with the
group of kids.  As I waited for his inevitable return, this girl approached
me from the side.

   "Hey, Sarah." I said, turning to her.  She, like me, was in the fifth
grade.  We didn't share a class together; our relationship was formed out
of the blue from the routine trek home, since a lot of students lived in
the apartment complex just across the street.  How it began I can't really
remember, but we developed a camraderie that you could loosely call a
friendship; most of our contact with each other was right here, so make of
that what you will.

   "So how was your sex-ed class?" I asked her.  "Did it traumatize you?"

   "Nope, it was completely boring and stupid!" she replied.  "Just mainly
talked about our stuff down there.  How about yours?"

   "They didn't really tell me anything I didn't already know.  It's more
like they just helped put the pieces together, but they used very simple
terms, like 'you put your thing in a girl's thing and stuff comes out.'" I
paused for a moment.  "Actually, that's the best way to describe it, is
that line right there extended over the whole hour."

   I was curious about what her class entailed.  I knew for a fact that the
sex-ed classes for boys and girls were separate, so we likely were taught
very different things.  I wouldn't say this around a grown-up, or anyone,
really, but I had an itching curiosity about girls and all their stuff down
there.  I remember years ago seeing another girl's stuff and how she was
completely blank down there except for this sort of cut where the skin
folded on itself.  But I didn't get to see a lot more than that.

   The crossguard escorted us across the street, where we let ourselves in
through the side gate.  We continued walking together, since she lived in
the apartment right next to mine, where our rooms shared a wall.

   Actually, I was very interested in girls, and lately, that interest has
been growing stronger.  The other boys were still on about cooties or
whatever, and wouldn't even get near a girl.  I didn't act the same way,
and as a result, they made fun of me.  A lot.

   I looked over at Sarah, whose attention was focused ahead.  I don't know
if grown-ups would consider her cute or adorable or attractive; at least I
did.  She had brown hair cut in a short bob, and she wore glasses.  Today
she was wearing a brown and red dress with white stockings - those are very
long socks that go up to their thighs.  She didn't have braces like some of
the other kids had, which was nice.  I didn't either, but I imagined them
to be very uncomfortable.

   We arrived at our apartments; the end of our seeing each other for
today. I fished around in my backpack for my house keys.  We were both
latchkey kids.  That's apparently what it's called.  It's what kids are
called when they let themselves into their homes because their parents are
otherwise not there.

   "Hey, would you like to come inside?" Sarah asked behind me.  I turned
around.

   "Huh?"

   "My mom and dad won't be home for a few hours.  It gets kind of lonely;
you...  don't have homework, do you?"

   "Yeah, but it's basic math stuff.  I'm good at math." I replied.  Sarah
unlocked and opened her front door.

   "Come on inside." she said, nodding inward.  I shrugged to myself. 
Sure, why not?  I stepped across the threshold and kicked off my shoes. 
She followed my lead.  Of course, it wasn't until Sarah closed the door
that I remembered one of my great anxieties.

   I wasn't good with strangers of any kind.  It's been a thing that I've
always had an anxiety for, and that also included going into other peoples'
homes.  As much as Sarah and I liked to chat in our short walk home after
school, I didn't know that much about her or her family, and the strange
house rules they might have.  It should be alright, though.  She lives
across from me; nothing bad should happen, and if it did, my mom would
easily find out.

   Sarah led me to her room.  It was not as pink as I imagined it would be.
Her bed was up against the window, which had a clear view out to the
street, and they had a kind of disgusting floral print on them.  At least I
found them disgusting; I didn't like elaborate prints on anything.  Her
room was very clean and straight, as to be expected; girls were usually
much cleaner than boys.

   "So uhh....  what do you want to do?" I asked.

   "I don't know.  What do you like to do?" she asked, sitting on her bed.

   "Play video games, watch Spongebob?  But I don't think you'd be really
interested in either of those?" she shook her head.

   "Actually, would you like to see my stuff?"

   "Your...  your stuff?" I repeated.  I felt a rush of heat to my face,
around my cheeks and nose.

   "Yeah, my stuff here." she patted between her legs.  The heat in my face
intensified.  "I'd...  also like to see yours."

   That made me feel even more anxious.  The only people to see me naked
were my parents, and that wasn't for many years, not since I learned how to
bathe myself.

   Sarah didn't wait for me to answer.  She pulled off her stockings down
to her feet and kicked them off, exposing her creamy legs.  My eyes were
locked on her, despite my embarrassment, and I couldn't look away.  She
noticed this, and she smiled.  She lifted her skirt up, revealing the pink
pair of panties she was wearing.  They were completely featureless.  Aside
from the seams along the edges, there were no other details or redundant
seams on them like on my "tighty whities" grown-ups like to call them. 
There was no bulge, either, but that's because I knew there was nothing
there.

   "There, now I'm in my underwear.  You should do the same.  That's what a
gentleman should do." she said, pulling the dress up over her head and
tossing it to the side.  I felt like a giant spotlight was shining on me
for all the world to see, but I knew there was no one else here but us. 
With considerable apprehension, I took a deep breath and I unzipped my
pants, letting them fall to my feet, where I stepped out of them.  I
removed my socks, and then took my shirt off.  It was very embarrassing,
standing here in a stranger's house, in nothing but my underwear.  Sarah
didn't seem to have the same qualms about it, though.  She was smiling at
me, which was a very adorable smile.

   Her chest was as flat as mine.  Most girls were, and some had slight
mounds.  Yeah I noticed that.  It was difficult not to.  My mom had very
large breasts.  I wondered why that was the case, and why girls didn't have
any when they were young.

   "Time for the underwear to come off." she said, standing up and
approaching me.  "Are you ready?  We'll do it together." She gripped a hand
on her underwear, and the other on mine.  I nodded, and did the same.

   "One...  two...  three!" we tugged our underwear down, letting them drop
to our feet.  Suddenly there we were, completely naked, and Sarah was like
a whole different person.  I allowed my eyes to explore her body, which was
softer than mine, with more curves around her hips and waist.  They curved
more than mine did, and something about it made me feel more...  I think
the proper term is interested.  Whatever it was, I wanted to keep looking
at her.

   What really drew my attention, though, was her stuff.  I sort of envied
her.  My stuff just dangled there between my legs, and it was very
uncomfortable sometimes.  For her, there was nothing there save for that
little slit where the skin folded on itself.  It looked like it could take
my thing.  Curiosity gripped at me.  What was inside the slit?  How far did
it go in?  They didn't mention this in the sex-ed class.  All they said was
that I stick my thing in it and...  something...  comes out.

   The whole time, Sarah was sizing up my stuff.  I occasionally glanced at
her and watched her expressions change around.  At first she was in awe,
then switched to fear, shock, and suddenly, she was happy.

   "It's...  very strange." she commented.

   "I could say the same about yours." I replied.  "Uhhh...  do you mind if
I can take a closer look at it?"

   "I was going to ask the same thing.  Come on, let's lie down on my bed.
That way, we can get a better view of each others' stuff at the same time."
I followed her to her bed, where she laid down on her side facing the
doorway.  I laid down in the opposite direction so I got a direct view at
her lap.  She had no qualms about taking a firm grip of my stuff and moving
it around, probably examining it from every angle like it was some kind of
strange bug.  It felt a little good.  I wriggled my hips around as a good
shock went up my back.  I reached up and dipped a finger into her slit.  I
could immediately feel as I moved my hand there a wave of moist heat
radiating from it.  It was very strange; my stuff didn't do that.

   The instant my finger went inside, I heard Sarah take a sharp breath,
and something inside her slit closed tightly around my finger. 
Instinctively, I drew it out, but when I saw there was no reason to be
cautious, I dipped my finger in her again.  Sarah's breathing became
louder, and the slit tightened around my finger again.  Why did it do that?

   I could feel my stuff getting long and stiff again, as I knew it to do
many times.  She tugged at the loose skin on it.

   "Yours is different from my older brother's." she said.

   "How is it different?" I asked.

   "He doesn't have this extra stuff right here." she tugged again at the
extra skin around the end.  "It stops right here." she tapped on the part
of my stuff just below the strange bulb at the end.

   "I see.  I wonder why that is?" I wondered out loud.  Turning my
attention back to her stuff, I put my index finger from my other hand into
her slit and gently and slowly pulled them apart, opening the slit even
wider.  Sarah gasped and breathed heavily, but it didn't sound like she was
in pain.  Her insides were like the inside of my mouth.  It was very pink
and many folds of flesh folded on themselves and tensed up, preventing me
from seeing further into her.  It was a very strange thing, but it was also
very mesmerizing.

   As I examined inside her slit with awe, I noticed that in the front,
where her slit began, there was a strange fold of skin that came down from
the outer folds in this sort of V shape.  where it ended, I saw a tiny
pink...  thing.  I don't know how to describe it.  It was about the size of
my pinky.

   "What is this?" I asked, prodding it with a finger.  Sarah whimpered
loudly and trembled in response.  I quickly pulled my finger away.  "I'm
sorry, Sarah!  Did that hurt?"

   "No...  no, that felt...  really good." she panted, pulling closer to
me. "Do it again!"

   "Uhh, okay..." I prodded the nub again, this time a little harder, and
she gasped again.  I continued my treatment, and that made her legs tremble
with delight.

   "Uhhh!  Yeah!" she moaned.  "Now rub it!  That'll feel really good!" I
complied, and ran my index finger up and down against the nob.  She
trembled even more violently, but she continued to urge me on.  Something
about this made me feel very hot and bothered, and my stuff started
throbbing and burning with a unique desire unlike any I felt before.

   Sarah's whole body suddenly tensed up next to me, and I could see the
muscles around her slit contract multiple times.  It was about half a
minute before it finally stopped, and her body relaxed.

   "What was that all about?" I asked, sitting up to face her.  My stuff
was still sticking straight up like a flag pole.

   "That...  I think that was my orgasm." she panted.

   "Orgasm?  What is that?"

   "It's that thing that happens when you feel really good during sex." she
answered.

   "Oooohhh right, that's what it's called?"

   Sarah nodded her head.  "Yup, and you were the one to give me my first
one."

   "How do you know what it's called, anyways?"

   "I snuck a few peeks at my older brother's porn collection." She drew
away from me and plopped her butt down on the head of the bed so she was
resting on the small stack of pillows.  She spread her legs apart and
opened her arms.

   "I'm ready to take you into me.  Are you ready to be my first?" she
asked.  Her slit, I noticed, was very moist.  Her face also bore a heavy
blush, it was as red as a tomato.  I nodded my head and crawled up to her,
guiding my stuff to that little slit between her legs.  I got the tip in,
and I immediately felt the muscles tighten around me, making me wince and
tremble.  It wasn't painful.  In fact, it was the most wonderful thing I
ever felt.  Slowly, I pushed the rest of the length in until our laps
touched, then I rested my body on top of hers.  She shivered with delight
and smiled at me, then wrapped her legs around my back and pulled me in
closer.  Our stomachs pressed together and our faces were only inches away
from each other.  It was at that moment that I saw her in a completely
different light.  She was no longer just a friend, but something much more.

   All the things that I found attractive about her seemed to be more
defined than ever.  The way she stared into my eyes with this funny look,
the feeling of her skin against mine, her hands running across my back.  It
all added up to this wonderful experience unlike anything he ever felt
before.

   "So what now?" I asked.  "You know more about this than I do,
apparently."

   "Now, move your hips back and forth." she said.  "And don't stop,
whatever you do." She grabbed me by the back of the head and pulled me in
for a very grown-up kiss.  I never had a grown-up kiss before, and in the
movies it always looked a little gross.  And messy.  Turns out that's only
what it looks like from the outside.  If you're one of the participants, it
is an incredible, very affectionte feeling.  I never felt this connection
with another person aside from my mom, and I never got to do this sort of
thing with her.

   I started moving my hips back and forth into her, pulling out until my
stuff was almost all the way out of her slit, and then pushing back in so
our stomachs slapped together.  This wonderful feeling immediately surged
through my lap.  Sarah's muscles gripped me tightly like a fist and refused
to let go.  It made thrusting into her and pulling back out a lot harder.

   I sat up off of her and braced my hands on either side of her and
pounded my hips into hers with incredible force and vigor.  My stuff felt
like it was burning down to the very core.  The pleasure was almost
unbearable, but my body seemed to have a mind of its own.  The room was
filled with our gasps and moans.  Sweat covered our bodies, and Sarah's
glasses were askew.

   "I feel...  so good!" I moaned loudly.

   "Mmnn me too!  Let's go together!" she cried out.  Seconds later, an
unbelievable sensation washed over me like a tidal wave and my stuff pulsed
like a heart against the tight muscles inside Sarah's slit.  It forced a
loud feral moan out of my throat.  I arched my back and threw my full
weight into her.

   Sarah whimpered and cried out in bliss in a way that sounded like she
was in pain.  Her muscles contracted around my stuff with incredible
intensity, pulsing many times that I was too exhausted to count.  Her legs
tightened around my waist and her arms wrapped around my neck and pulled me
down on top of her, where she smothered me with kisses.

   We came down from our incredible high.  I was still inside her, my stuff
still at attention.  I preferred it there.  After experiencing her hot
insides, I didn't want to leave.  Sarah took off her glasses and, twisting
her arm back, placed them on the nightstand next to her bed.

   "So that was very fun and exciting." I said.  "How was it for you?"

   "Incredible!  I really enjoyed it." She pulled me in for another kiss.
It was very slow and tender, and I could feel a unique sense of affection
coming from her, a type that even my mom didn't give me.

   "You were my first..." she whispered, tracing a finger across my chest.

   "Yeah, I was.  What does this mean for us?" I asked.

   "I dunno.  I think it means we're boyfriend and girlfriend now.  Do you
like me?"

   I blushed heavily.  I never really thought about her as a girlfriend
before.  Yeah, she was a friend, and a girl, and I was her first, and she
was mine.  I also thought she was very attractive and cute, especially now
that we had sex.  I would definately like to do this again.  The answer was
obvious.

   "Yeah, I like you.  I really like you." I said.  Apparently that's the
answer she was hoping for, for she smiled widely and threw her arms around
my neck and pulled me into a tight bear hug.

   "Oh thank you!" she exclaimed, and kissed me again.  I returned the
favor.  I hugged her and kissed back as she pulled the bedsheets over us.
From the outside, it looked very innocent and cute, but underneath we were
in a very grown-up position.

   "It'll be another couple of hours before my parents get home." Sarah
said.  "I want to go again as much as we can before they do."
