 My name is Alan, I'm 21 years old.  I was born in the upper Midwest to a
small town pastor and his wife.  Just before my little sister was born, we
moved to the Northwest.

   We grew up in a pretty normal household, we never had much money,
pastors very seldom do, but we didn't lack for much either.  Mom and dad
loved us and supported us as best they could, they were always there for us
no matter what we did.  This is the story of how my sister and I first
started enjoying each other.

   First, a little about us.  I take after my dad's side of the family. 
I'm 5'10" and weigh 220 lbs.  and I play football in college.  My sister,
Sara, takes after mom's side of the family.  Mom's not very tall, but
grandpa is.  Sara is over 6 feet and weighs about 160.  She's very athletic
with a build to match.  Not a super model, but she's really pretty.  She
has shoulder length dark brunette hair, beautiful high cheek bones, light
blue eyes and a smile to die for.  She also has the cutest laugh.  Her
breasts are 38 DD, and don't sag much.  She has a six-pack of abs that
makes the guys on the football team jealous.  Her ass blends nicely into
her best asset, her legs.  Long, shapely and athletic.  She plays
volleyball, basketball.

   She is just starting her freshman year at the same college I play for.
The basketball coach asked her to walk-on and told her she had a good
chance to make the team and red-shirt her frosh year.  I told her to go for
it.  I red-shirted and it's really paying off this year.  I'm the #2
running back behind a senior who should have gone to the NFL last spring
but wanted to finish school and I'll get plenty of playing time.

   We've always been close as brother and sister, did all the things
brothers and sisters do, played together, took baths together, and
sometimes fought like dogs and cats when we were young.  We could never
stay angry with each other long though.  Mom just knew how to help us see
the other point of view.

   We were always attending each others events, sports or otherwise as we
grew up, and we constantly challenged ourselves and each other to get
better.  That's the main reason we grew so close.  We understood that even
though we were competitive we weren't competing against each other.  Only
in golf and tennis, and then it was no holds barred!

   I'd always been protective of Sara, and she of me.  We made sure we had
each others back when it came to dating.  She'd let me know which girls to
avoid, and when a jerk of a guy came around I'd make sure he understood she
wasn't interested if she couldn't make him understand herself.

   Growing up we had separate bedrooms but shared a bath.  It seemed we
would always be walking in on each other when we were in the shower or
whatever.  Neither of us made any big deal out of it.

   Things changed when I turned 12 though.  I started to grow pubic hair,
and started to get shy.  One time, she walked into the bathroom just as I
was getting out of the shower.  I jumped as I grabbed a towel.

   "You could have knocked," I said.

   I wasn't really upset, but I wasn't comfortable either.  Looking back I
think I was more startled than anything.  She just looked at me with a
blank look on her face and asked what was wrong.

   I turned red and muttered something about privacy and turned around. 
She left without saying anything, but I could tell she was a bit hurt.

   I dried off, put on my shorts, and went to my room to get dressed.  I'd
just put on my jeans when I heard a soft knock on my door.  It was Sara.

   "I'm sorry," she said.

   "That's okay." I replied.  "You just startled me.  I didn't mean to
yell." I gave her a hug and she hugged me back, smiled that award winning
smile of hers, and left.

   Sara hadn't started to develop yet, but it wouldn't be long because
about three months later, I walked in on her without knocking.  She'd just
finished peeing and was getting ready to take a shower.  Her breasts were
just starting to grow and there was just the barest amount of fuzz around
her pussy.

   "You could have knocked," she said, kind of sarcastically.  I turned red
again and backed out of the bathroom.  I heard the shower turn on and then
knocked on the door.  She hollered to come in.

   By this time I was masturbating pretty regularly, and when I got back
into the bathroom, I had a raging hard-on.  I also had to pee pretty
badly...difficult to do in that condition.  I stood there for a while
waiting to get soft so I could pee.  By then, Sara had finished her shower.

   "Alan, are you still in here?" she asked

   "Yes."

   "What are you doing?"

   "Trying to go to the bathroom"

   "What do you mean, trying?"

   I turned really red and didn't answer

   "What do you mean, trying?" She asked again

   "It's difficult to explain." I said

   By this time she'd stepped out of the shower and gotten her towel. 
There I stood with my dick still pretty hard, trying to pee.  She looked at
me and her eyes got big.  I tried to hide, but the bathroom was pretty
small.

   "Alan, what's the matter?" she asked

   "Nothing", I growled.  "I gotta pee and I can't when I'm like this."

   "Oh." Was all she said.

   I just left.  She dried off and headed for her bedroom.  I headed back
to the bathroom to take care of two needs.

   Neither one of us talked about what happened that morning, but without
saying anything we subtly changed our bathroom habits, for mornings at
least.  We both made sure the coast was clear before we headed there.

   About three years later when I was a freshman in high school, I came
home early from wrestling practice one night.  The talk in the locker room,
especially by the upperclassmen, was about the girls they either wanted to
or were going to lay that weekend.  I'd heard them talking about sex
before, but that night it really got me horny and I knew I needed to attend
to my personal needs pretty quickly.

   When I got home the house was quiet.  Mom and dad were at church for a
meeting, and as I walked upstairs I thought I heard Sara in her room.  I
didn't even think about it, and just walked into the bathroom.  There was
my baby sister, sitting on the toilet, fingering herself.  We both froze
and turned beet red.  I was in my sweat pants, and had been thinking about
the locker room conversation all the way home.  I was already pretty hard,
and seeing my sister sitting there naked with her fingers in her pussy
didn't help.  I nearly came in my pants.  Sara recovered first.

   "What are you doing home?" she nearly screamed.  "Get out!"

   I stood there for just a split second longer, then backed out and shut
the door, the image of my sister, now with a good rack started, and dark
bush, sitting on the toilet playing with herself was burned forever into my
mind.  Her breasts were rapidly approaching D cup, and she'd definitely
started to lose the baby fat.  It was obvious she was becoming quite an
attractive woman.

   I went to my room and sat down at my desk.  Between my hard-on and
seeing my sister like that, I really didn't know what or how to feel.  I
sat there for a couple of minutes trying to sort out my emotions.  I'd
never thought of Sara sexually before, and wasn't sure that's what I was
feeling right then.  I knew she was growing up and filling out and becoming
a woman, but I hadn't seen her naked for a long time, bra and panties
plenty of times, but not naked.  My dick was so hard it hurt, and I was
about to do something about it when I heard a knock at my door.  She didn't
wait for me to answer she just came quickly and closed the door behind her.
She had her bathrobe on.

   "Alan, I'm sorry I yelled; you startled me.  Don't tell Dad and mom.  I
don't want to get into trouble..." she kept babbling on.

   "Hold it!" I finally said, and she stopped.  Her head was down and I
could tell she was embarrassed.  It suddenly dawned on me this was probably
the first time she'd frigged herself.  It was at that point our
relationship changed forever I think.  I don't know what she knew about
guys, and most of what I knew came from the locker room.

   I knew my sister was a fox, and I'd do anything to protect her.  She
looked so vulnerable standing there I got up and gave her a hug.  She
started to cry softly.  At that point in our lives, we looked nearly eye to
eye.  It wouldn't be long before she looked down on me, but not yet.  I
took her head in my hands and looked at her.  I wiped a tear away.

   "First of all, I'm not going to tell Dad and mom.  Second, I'm sorry I
just walked in, I thought I heard you in your room, and to be real honest,
I need to do the same thing." Then almost without thinking about what I was
saying, I asked,

   "You wanna watch me?"

   She looked at me really funny, her eyes got big and her mouth just sort
of fell open.  Before she could answer and I lost my nerve, I took her hand
and walked over to my computer.  I sat her on the bed, turned my chair
around to face her, pulled down my sweat pants and took hold of my very
painful hard-on.  As compared with the rest of the guys on the wrestling
team, I'm not that well endowed.  Thank God for erections!  I'm about 7
inches long and about 3 ½ inches around.  I've been masturbating for a
while, but I'm still a virgin.  I really needed to cum, but I wanted this
to last too.  I could see Sara was not sure what to do, or where to look.

   "Just watch." I said

   She looked at my left hand slowly stroking up and down on my shaft.  The
pre-cum was oozing out the end and was plenty of lubrication for now.  She
stared wide eyed as I started to thrust my hips forward a bit.  I was
getting close and I knew it.

   "Can I touch it?" she asked

   I nearly missed what she said.  I stopped, took a second to be sure I'd
heard what I thought I had, and said "Are you sure?"

   "I think so," she replied.  Her voice was so soft I could barely hear
her.

   I let go, my cock nearly whacked my stomach, and she giggled.  Then she
reached out and touched the end with her finger.  I jumped.  It was the
first time a girl had ever touched there.  She pulled back.

   "Did I hurt you?" She looked startled.

   "No.  No one has ever touched me there before.  It felt strange, but
good strange.  Touch it again if you want."

   She reached out again and this time gently took my cock in her hand. 
She just held it for a moment and then started to rub back and forth like
she'd seen me do.  I stood there for a moment and again thrust my hips
forward.  I think I actually started to fuck her hand, I don't remember all
the sensations, they were coming way to fast...and so was I.  About the
time I started to tell her I was about to cum, I did.  Her robe had fallen
open a little, and I was pointed straight at her luscious tits and chest. I
erupted like a fire hose right in the middle of her tits.  She didn't miss
a stroke.  I didn't think I'd ever stop cumming, my knees got weak and I
sat down on my chair.  The room started to spin, and I nearly passed out.
When I focused again, Sara was looking at me like she'd seen a ghost.

   "Are you okay?" she asked very concerned.

   "Yea, I'm fine, great in fact.  That was incredible!  I've never cum
that much, ever.  You did great sis."

   "What is this stuff?" she asked

   "Cum," I answered.  "It happens when I beat off.  The guys say it's what
gets girls pregnant."

   "Oh," she said.  "It felt good?"

   "Oh yea!" I said, "It always does, just this time when you did it, it
felt better than when I do it myself."

   "How often do you do it?" she asked.  Sara was always good at asking
questions and this really had her interest.

   "Almost everyday," I said.

   "How often do you do it?" I asked though I was pretty sure of the
answer. I didn't want her to know that though.

   She looked down at the floor and in a voice barely above a whisper, she
admitted that was her first time.  She'd heard some of the older girls
talking about it and decided to try it.  She wasn't sure what to expect so
she thought it was best if she tried in the bathroom.

   "Did you cum?" I asked

   "I don't know." She said.  "It was starting to feel good, and then you
walked in".

   "Would you like to?"

   "Cum?" She answered.

   "Yea."

   I took a chance.  I'd never touched a girl before, but with all that cum
on her chest, I figured I didn't have anything to lose.  I reached gently
to her robe and pushed it off her shoulders.  She started to cover herself
with her arm, and then stopped and put it back on her lap.  She looked in
my eyes and I could see she was a bit scared, but she was willing to trust
me.  I reached between her tits and rubbed a bit of cum around on her chest
and moved towards her tits.  She shuddered and closed her eyes.  I stopped.
She opened her eyes and said, "It's okay."

   I reached out again and started to rub lightly around her tits.  I began
with light strokes where they started out from her chest and then slowly
moved down toward her hardening nipples, first one then the other.  She
took a deep breath and shuddered lightly again.  I'd never felt anything as
soft and wonderful as those tits.  Then I moved down her stomach toward her
belly button.  She lay back on her elbows on my bed and watched as I opened
her robe all the way.  This time she didn't move to cover up.  I was
drawing the cum down her belly as I went.  She closed her eyes again and
took a deep breath and lay down on her back.

   As I was concentrating on her tits and belly, she moved her hands to her
furry mound.  I could smell the womanly musk coming from her, and started
to get hard again.  I moved my motions back up to her tits as she started
to rub her slit.  She spread her legs and I got my first real look at a
pussy.  I couldn't believe the feelings that were making their way into my
brain.  As I watched and rubbed, she was rubbing too.  I moved my hand down
between her legs and rubbed her inner thighs.  She spread her legs further
apart and I could see the moisture glisten.  She didn't stop me when I
rubbed higher and closer to that wonderful patch.  I let my thumb slide
over the outside of her lips.  She twitched but she didn't move my hand. 
"Here goes" I thought.  She was rubbing her love button, so I took my
finger and rubbed it up and down on her slit.  She moaned softly,pulled her
knees up and spread her legs wide.  I slowly slid my finger into her
waiting cunt to the first knuckle.  She lifted her hips slightly as I
pulled back.  I pushed in a little further.  By this time I was rock hard
again.  As I pulled my finger out again, she opened her eyes and smiled at
me.

   "Keep going" she whispered.

   Not wanting to keep the lady waiting, I slid my finger all the way in as
far as it would go.  I felt something give a little and figured it must be
her cherry.  I'd heard the guys talking about that in the locker room, and
how girls bled when it popped.  I didn't want blood all over my bed, and
try to explain that to mom, so I stopped there.

   By this time, Sara was breathing very raggedly and starting to moan. 
"Keep going" she said again.  I started to finger fuck her carefully. 
Suddenly she tensed up and tried to crawl up my hand.  She jerked around on
my finger wildly.  When I tried to pull it out, she grabbed it with her
other hand and held it there.  It seemed forever before she quit
shuddering. I was starting to sweat, and I was going to need some attention
again before the night was through.  She took a deep breath, sighed loudly,
and stopped shuddering.

   I crawled up on the bed beside her with my finger still in her pussy. 
She rolled to me smiling, and said, "That was amazing." As we lay there
looking at each other, neither one of us knew what to say.  She closed her
eyes and I think she may have fallen asleep for a moment because her
breathing got really slow and regular.  I carefully pulled my finger out,
and she opened her eyes.  She smiled at me and touched my cheek.

   "I loved that." She said

   "I did too, and I'm going to need some attention again."

   "Maybe we can do it together again soon." She said and smiled.
