 I'm Sophie.  I'm 13 years old and have brown curly hair that hangs down to
my upper chest.  I have brown eyes, I'm about 5'2 and have a few freckles
that cover a small part of my face.  I have very small boobs, only a 32A,
and I'm really embarrassed by them.  My friends all have big boobs, or at
least bigger than mine.  My friend Erin has the biggest, at a 26C, which is
really big at her age, and then my best friend, Grace, has 24Bs.  I've only
ever shown Grace my tits, because I trust her more than anyone else.  Oh,
and Beth, my sister.  Beth is 10, and we always walk around the house
either nude or topless, since it's only me, mom and Beth in the house.  Mom
doesn't mind really, since I've promised to dress up again if someone comes
round.  Beth only has to put underwear back on, since she hasn't started
puberty yet and has no breasts.  Beth usually answers the door to my
friends if they come round, topless.  This used to freak my friends out,
but now they're used to it.  In my room, Grace takes her top and bra off.
We don't see the need for modesty if we're in a private place.  Beth is
about 4'7, has long straight ginger hair, and freckles all over her face
and arms.  Grace is taller than me, at 5'4, and has straight brown hair
that hangs down to her boobs.  Like I said, her boobs are bigger than me,
and although I'm jealous, I don't mind too much because Grace always says
I'm really pretty.  It always makes me really happy when she does, because
I'm quite self conscious. 

   Grace was gonna come round one day, so I was preparing by putting make
up on, and putting some panties on.  Since I do walk around in my underwear
a lot, I buy quite nice bras and panties.  The one I was wearing that day
was a black lace thong, which only covered up my actual pussy, but not my
hips or ass.  I didnt mind though, because I find thongs really comfy, and
so did Grace.  I didn't bother putting on a bra, because I knew only my
best friend was coming round. 

   When Grace knocked, Beth ran for the door.  Beth was only wearing
panties - just simple white ones.  Grace was used to Beth opening the door
in such a manner, and asked if I was ready.  I called up to her, and
beckoned her into my room.  Grace walked in and noticed I wasn't wearing a
bra, and proceeded to take her top off.  She was wearing a tight blue t
shirt, and her bra was black and White polka dot.  She then took it off,
revealing her really pretty B cup breasts.  Next she slid down her skirt,
which was a simple black pleat, revealing her panties that matched her bra.
For a while we both just sat in our underwear, chatting about boys and
girls etc. 

   Soon though, Beth walked in, completely naked.  This would've shocked a
lot of people, but me and Grace were used to it.  This time though, things
were different.  Beths crotch was soaking wet, and She looked quite
scared.  'Beth!' I said, 'Whats wrong?' Beth calmed down a bit, and blushed
deeply.  'Well, I was lying on my bed, naked, and my pee pee started
getting wet.  I wondered what was going on, and put my finger in there. 
This felt really good, so I kept going.  Then...' she paused, and looked
down at her pussy.  'This happened.'  I turned away from my sister and
looked at my friend, who looked perfectly calm.  'Its okay Beth, lots of
girls do that to feel nice.  I bet your sister has done it!' 'What?' I
cried, 'No!' Grace looked at me quizzically.  'do you want to try it?  With
us' she asked.  I looked at her, then at Beth, who nodded.  I slowly nodded
my head, and slid my thong down.  I only had a fine layer of hair covering
my pussy, but saw to my surprise, that Grace had none when she slid down
her panties.  I asked why, and she said that she hadn't grown any yet, and
she was embarrassed about it.  It made me feel a little better because both
of us had something we were embarrassed about.  We all moved one finger
down to our pussys, mine with a fair patch of hair, Graces bare slit, and
Beths that was completely hairless.

   All at once, we pushed our fingers in.  My snatch was weird, slippery
and damp.  I felt a strange sensation pulse up my pussy, into my spine and
up my neck.  It was odd, but nice all the same.  Grace shivered when she
put her index finger into her bare cunt.  She slowly closed her eyes and
started moving her finger in small circles in her pussy.  Beth was almost
as inexperienced as me, and was just moving one finger in and out of her
undeveloped cunt.  I was reluctant to continue fingering myself, but as I
heard Grace let out a small moan, I felt an emotion I'd never felt before.
I...  Wanted pleasure.  I brought one hand up to my tit, and started slowly
massaging the erect nipple.  It felt really soft and great, and I also
started moving my finger up and down my pussy in time with my circling.  I
moved my finger up the length of my slit, still feeling strange, until I
hit a little hard nub and an intense feeling of pleasure rushed up my body.
I gasped loudly, which caused Grace and Beth to stop. 

   'Having fun, Soph?' Grace asked, winking at me.  I felt a whole new kind
of feeling for my best friend.  I think it might've been love.  It was
strange, but a really nice feeling.  'Um, yeah,' I said, blushing.  'Erm,
how can I make it better?  Like, it's weird but I want more.' Just that
second, my friend Ben walked in.  He was so a very close friend and had
seen me topless, but not braless obviously.  He stopped, and saw three
girls sitting naked on my bedroom floor.  'Sophie?!' Ben cried.  Grace
looked from me to Beth to Ben, and saw he had a massive bulge in his
pants.  'Ben I'll be blunt,' said Grace, 'This is what it looks like.  Now,
do...  You want to get involved?'  Ben looked shocked, but didn't get
worried.  He slowly nodded his head.  Grace told him to strip naked, and he
complied.  He quickly took off his socks, shirt and pants, leaving his
boxers.  He pulled his boxers down and revealed his 5" dick.  Seeing it for
the first time made my pussy feel really weird.  'Um...  Ben, please, do
me.'  Ben still looked on at me in awe, but complied.  We moved onto my
bed, and he lay me down on
