 �>�The Sister by by Lady Lucia

   Part Six

   For a small girl, Natalie had a pretty solid ass.

   I had already gotten a good look at it when she was bent over to collect
her things in the car earlier, though I had tried not to stare at the time.
It was more difficult to look away, however, when she was ahead of me on
the stairs.  Her pink bikini bottoms hugged her hips tightly enough that I
could actually see the shape of her pert rear as she took each step.

   Looking was okay, right?  That wasn -(TM)t cheating.

   Since I had to keep my eyes forward anyway, since there weren -(TM)t
many other options as we ascended the stairs.  So, for a few seconds, I
indulged myself and took a good, long stare at Natalie -(TM)s ass.  Since
she was wearing nothing but a bikini, I could clearly see every way her
lower body shifted as she took each stair.  If Natalie hadn -(TM)t said
anything a minute ago, perhaps I could -(TM)ve just checked her out and
moved on.  But she had practically invited this;  -~Enjoy the view, -(TM)
in that lilting, innocent yet not so innocent tone.  And I couldn -(TM)t
really help myself from doing exactly what she wanted.

   At least she didn -(TM)t glance back and catch me in the act.

   When we reached the top of the stairs, Natalie just turned the corner
like nothing was going on.  Walking through the lake house like she owned
the place; which she did, by extension.  But, even after just knowing her
for a half hour or so, I already suspected there was a method to her casual
behavior.  Not saying anything because she wanted to keep me in suspense.
Or maybe playing it cool to make me think I missed my shot.  Was it bad
that I wanted to know?

   Finally breaking the silence, Natalie said,  -�Here we are, babe. -� The
corner bedrooms were at the end of the short hall, right after the bathroom
and linen closet.  Now that I saw one door on each side of the girl, I
recalled Jessica telling me that we -(TM)d be across the hall from her
sister.  Before, it hadn -(TM)t made a huge difference to me.  Now, I wasn
-(TM)t so sure.  Both doors were open, and she gestured towards the one to
her left.   -�So are you sleeping with Jess tonight? -� Natalie asked,
before gesturing to the opposite door,  -�Or with me? -�

   Fuck.

   The answer was obvious -"with my girlfriend.  But there was just
something about her younger sister.  Despite her overt flirting, she didn
-(TM)t come across as  -~slutty -(TM) in the slightest.  That would -(TM)ve
made it easier to shut her down.  Instead, it was like she was weaponizing
her cuteness.  Looking innocent, but contrasting that image with her words.
Being clear with her intentions, yet being so nonchalant about them at the
same time.  And, of course, she was a visually miniature version of my
girlfriend on top of that.

    -�With Jessica, -� I quickly said.  Any hesitation, and the silence
would just encourage the tempting girl to make herself, well, tempting.

   Natalie gasped.   -�Oh my God, you -(TM)re sleeping with her tonight? 
When I -(TM)m right across the hall?  Wow. -�

    -�That -(TM)s not what I meant. -�

    -�So you -(TM)re not?  Because then you should sneak over to my room
tonight.  If Jessica isn -(TM)t going to give you what you need, someone
should! -�

    -�Natalie- -�

    -�Just think about it, -� she said, with a wink.  Then she turned and
sauntered through the first doorway she had gestured to.   -�Come on, babe.
This one -(TM)s your room. -�

   Maybe a quarter of me was actually hoping for something to happen with
this girl.  While I -(TM)d never make the first move, I -(TM)m not sure I
-(TM)d be able to help myself if she tried something.  At least, not when
she kept subtly flaunting her body and verbally throwing herself at me. 
But the rest of me was still determined to be faithful to Jessica, as well
as worried that this was all some kind of sick test.  One wrong move with
Natalie, and there was the chance that she -(TM)d run off and rat me out,
leaving me with neither sister.

   Although the more time I spent with Jessica -(TM)s tease of a sister,
the more I was convinced the flirt was acting alone.  It would be one thing
if she made a pass at me to see how I -(TM)d react.  But to play games for
this long?  That felt like something else entirely.  And, even though I had
an idea of what she was doing, I was still falling for it.

   I actually hadn -(TM)t seen the bedroom yet.  Natalie had arrived right
before Jessica had a chance to give me the tour, and the younger girl had
gone out of her way to attach us at the hip ever since then.  There were
two big glass doors that offered an amazing view of the lake, just like
Jessica had told me about, and there was a deck just outside the doors as
well.  My girlfriend -(TM)s duffel bag was sitting on the queen bed, still
open and a little messy; because she changed a few minutes ago.

   And then there was Natalie -(TM)s ass.

   The girl was fully bent over.  In the kitchen, the danger was how close
her backside was to brush against my crotch.  In the bedroom, however, it
was back to the matter of averting my gaze.  I had a perfect view of all
that bare leg, not to mention how her pink bottoms once again left very
little to the imagination.  She wasn -(TM)t just striking the pose for my
benefit -"well, not only for my benefit -"Natalie was going through my
suitcase.

    -�Hmm, no protection?  Shame.  Oh, here we are! -� Natalie snapped back
up with my swimsuit in her hand

    -~That -(TM)s because the condoms are in my backpack. -(TM) Except I
would never give her ammo like that when she had already taunted me about 
-~sleeping with Jessica. -(TM) Instead, I just went with a simple, 
-�Thanks. -�

    -�Alright, -� she said, eyeing me up and down for a moment,  -�Strip
for me? -�



   Part Seven

   The surprise on my face must have been obvious.

   Strip?  Surely Natalie couldn -(TM)t be serious.

   And yet, I couldn -(TM)t help but notice the look on her own face. 
Interest, and curiosity, as she gave me that once over.  It was one thing
when she teased me by flaunting her own body, but the thought of
reciprocating in a similar manner was something else entirely.  I couldn
-(TM)t do that; I had a girlfriend.  Either Natalie was flirting with me
just for the sport of it, or she actually wanted me.  And it was my job to
somehow thwart the advances of a sexy girl who was throwing herself at me.

    -�Natalie, I -(TM)m dating Jessica, -� I said.  The best way to deal
with teasing interest was to be direct, right?   -�You and me?  It -(TM)s
not happening. -�

   Instead of the cute pout that I expected based on her response to my
last few  -~rejections, -(TM) she dropped her jaw for a moment in
exaggerated shock.   -�Jess is my sister! -� she exclaimed,  -�I -(TM)d
never dream of stealing you away from her like that. -�

   Says the girl who openly stated that she wanted to fuck me.  But if she
was dropping it, then I wasn -(TM)t going to complain.  The fantasy might
be hot, but the reality would be a nightmare.   -�Good.  Then- -�

    -�But I do need to make sure that she -(TM)s being satisfied, -� she
said, cutting me off,  -�So I -(TM)m going to have to try you out for
myself.  Don -(TM)t worry.  I -(TM)m sure you -(TM)ll pass with flying
colors, and then you -(TM)ll have my approval for life! -�

   Just like that, we were back.   -�Natalie- -�

   She sighed dramatically enough to cut me off.   -�Fine.  If you -(TM)re
going to be a prude about it, then you don -(TM)t have to strip all the
way. Just let me take your shirt off, okay? -�

    -�Umm . . . -�

    -�What?  There -(TM)s nothing wrong with a guy being shirtless.  Is it
really that big of a deal if I help you out?  It -(TM)s harmless.  And what
Jessica doesn -(TM)t know, won -(TM)t hurt her.  Right? -�

   I hesitated for a moment, weighing her words.  She had a way of
explaining things in a way that made sense, while also addressing the
potential issue instead of avoiding it.  It -(TM)s socially acceptable for
a guy to walk around without a shirt on, sure.  The rest got a little hazy,
however.  It wouldn -(TM)t necessarily be a big deal for Natalie to 
-~help, -(TM) but it also wasn -(TM)t exactly appropriate.  Though she was
right; Jessica wouldn -(TM)t know.

   But I would.  And Natalie would.

   It really was tempting, when coming from a mini-Jessica who was wearing
nothing but a skimpy pink bikini.  Still, I couldn -(TM)t in good
conscience let her strip me, could I?  Even if it was just my shirt.  
-�Look, Natalie . . . -�

   I barely made it that far.  She stepped forward and placed both of her
hands on my shoulders, looking up at me with deep eyes and a soft smile.  
-�It -(TM)s okay.  You can trust me, -� she said.  Never taking her eyes
off mine, her soft hands trailed down my chest, over my abdomen, and paused
at my waist.  I -(TM)m not sure whether or not I would have let her roam
further; thankfully, she didn -(TM)t put me in that position.  Instead, she
began fiddling with the hem of my t-shirt.   -�Ask me, babe. -�

   For a second, I was too stunned to speak.  The last thing I expected was
that kind of contact, but her touch felt too good to ignore.  Instead of
the gentle way Jessica tended to glide her hands from point A to point B,
the way I had gotten used to after only being with the same girl for a few
weeks now, Natalie kept full contact the whole time.  Her fingers and palms
fully pressed into me on the way down, only leaving herself enough space to
continue the movement without too much friction.  If that wasn -(TM)t
enough, the eye contact was impossible to ignore.  Her gaze was expectant,
yet patient.  There was an innocence to it as well, despite her not so
innocent actions.

    -�Ask what? -� I finally managed to get out.  With one touch, one drawn
out movement, it was like the entire dynamic between us had changed.  I was
still mentally present enough to be aware of who she was and why we shouldn
-(TM)t be doing whatever we were doing, but I didn -(TM)t have nearly as
much resolve as I did a few minutes ago.

   Natalie slipped her hands underneath my shirt and rested them on my bare
sides, just above my waist.  They were soft, and warm.  And too still, now
that I had experienced what it felt like when they were more active on my
body.   -�Ask me to take off your shirt, -� she simply said.   -�No, wait.
Ask me to strip you.  That -(TM)s more fun. -�

    -�Just my shirt? -� I hesitantly asked.  This was harmless, according
to Natalie.  Not technically cheating, right?  Just like when I stole a
glance or two on the way up the stairs, it -(TM)s not like we were actually
doing anything.  She would just be removing my shirt.  In the back of my
mind, I knew it was wrong, but told myself it was fine as long as nothing
happened.

    -�Mm hmm, -� Natalie hummed, with a small nod of her head,  -�But I
have to hear the magic words, -� she said.  Her fingertips idly traced my
bare sides, and her eye contact was as casually fearless as ever.   -�
-~Please strip me, Natalie. -(TM) You can handle that, can -(TM)t you? -�

   I found myself nodding as well.  Like she said, it wasn -(TM)t a big
deal.  Guys took their shirts off all the time, often in public.  She was
just helping me out.  Totally harmless.  Obviously, this had nothing to do
with the fact that Natalie was a hot eighteen year old with amazing hands
and captivating eyes.  Obviously.

   So, with barely any hesitation, I said it.

    -�Please strip me, Natalie. -�



   Part Eight

    -�Good boy. -�

   I don -(TM)t know why, but those two little words had quite the effect
on me.  For starters, no one had ever said it to me before.  It was one of
those things that you didn -(TM)t realize you wanted until it was offered
to you.  And to be spoken to like that by a younger girl?  It didn -(TM)t
come across as patronizing in the slightest, but it was still unexpected
and confusing all at the same time.

   If there was something I should have said in response, I lost my chance
pretty quickly.  Now that Natalie had succeeded in getting me to ask her to
strip me, she got right to work.  Teasing as ever, the girl slowly lifted
my shirt.  Whatever fingers weren -(TM)t involved in gripping the dark
fabric remained on my bare sides.  I could feel them tracing upwards, and
could follow her gradual pace.  Her eyes hadn -(TM)t left mine in quite
some time, and we stood in suspended silence until she finally broke it.

    -�Arms up, babe, -� Natalie said.  While she waited, her hands casually
rested on my chest.  Soft, and warm, and gently pressing into my bare skin
with the unspoken excuse of using them to keep my shirt from falling back
down.

   It was getting difficult to resist her.  With barely any hesitation, I
lifted my arms so she could continue my shirt -(TM)s journey.  It was
easier to justify things this time around, as letting her take the shirt
off completely was more  -~appropriate -(TM) than delaying any action and
letting her hands remain where they were.  Granted, the right thing to do
would be shutting this whole thing down and getting some privacy to change.
But it was impossible to ignore how good her touch felt, and I was
admittedly curious what she was planning.  As long as it didn -(TM)t cross
any serious lines, I was willing to indulge myself now that Natalie had
worked her way past my first line of defense.

   Natalie lifted the black v-neck past my shoulders and over my head, and
surprised me with yet another move right as soon as I lost sight of her. 
All of a sudden, I felt her chest pushing into mine.  She must have taken a
step or two forward, and her bikini top didn -(TM)t do much to hide how her
smaller breasts felt against my body.

   If I was single, this would have been something else entirely.  Despite
the temptation, however, I tried to take a step back.  Honestly, I wasn
-(TM)t sure where the next line even was now that Natalie had blurred the
first one so much, but something told me that this was inching too close to
it.  She was ready for me, like always.   -�Come on; stay, -� she said, 
-�Be brave. -� Both of her hands gripped my bare sides again, softly yet
assertively; this time, without my shirt in the way.  She pulled me back
towards her, simultaneously pressing herself forward into me.

   Still blinded by the v-neck, I had to make a call.  Natalie probably
wanted me to finish the job of taking off my shirt, as the new position of
her hands meant that my arms were already trusted to hold it in place
around my head.  If I didn -(TM)t finish stripping my top half, I -(TM)d
either be stuck as we were, or I -(TM)d somehow have to pull it back down
while the two of us were so intimately connected.

   The thought of Jessica crossed my mind, and I was instantly at war with
myself.  Be faithful, and push away the hot girl throwing herself at me? 
Or keep playing along with Natalie, and hope that I don -(TM)t do something
I regret when the brain below my waist was the one making more of the
decisions?

   Natalie must have sensed my inner turmoil, or perhaps she was just
impatient.   -�You are brave, aren -(TM)t you? -� she asked.  Idly rubbing
back and forth with her thumbs as she held me close, I could feel her
breasts shifting against me as she adjusted her body -(TM)s position.

    -�That -(TM)s not fair. -� I began pulling the top over my head, not
wanting to be awkwardly stuck without seeing anything, while I tried to
address the girl -(TM)s question.  Of course I was brave, but a  -~yes
-(TM) was instantly going to be used against me in this context.  But I
also couldn -(TM)t say  -~no. -(TM) Not only was it not true, but I could
already imagine how she might use it against me.   -~That -(TM)s okay.  I
-(TM)ll teach you, babe.  THIS is how to be brave. -(TM) Fuck, that was a
dangerous string of thoughts.  A fleeting fantasy conjured up in the
moment, and one that made me lean a little more towards Natalie as I
continued my internal struggle.

   The first thing I saw was Natalie -(TM)s face, mere inches from mine.  I
guess I should have expected her to be so close, considering how our bodies
were pressed together above the waist, but nothing really prepared me for
the mischievous smirk and expectant eyes she was greeting me with.   -�What
-(TM)s not fair? -� she murmured, leaning in the slightest bit and ever so
slightly cocking her head to the side.

   God, it would be so easy to lean forward and kiss her.  It honestly wasn
-(TM)t even our proximity; instead, I found myself melting against her
wildly attractive expression.  It conveyed a sexy confidence, with just a
dash of cuteness that made her all the more tempting.  Not to mention how
wrong this all was, which was both nerve inducing and yet a little bit hot
at the same time.

    -�You know what I mean. -� Rationally, I knew I should slam on the
brakes.  Push her away.  But I couldn -(TM)t.  Natalie -(TM)s stare was
intoxicating.

   She leaned further forward, gracefully lifting up on her toes to put
herself closer as well.   -�If you -(TM)re brave, -� she whispered, closing
her eyes and nudging my nose with hers,  -�Then prove it. -�

   Natalie lightly brushed her lips against mine . . .



   Part Nine

   If this were a build-up to a normal kiss, my eyes would have been closed
the moment she started leaning in.

   But this wasn -(TM)t a normal kiss.  It was Natalie; it was Jessica
-(TM)s younger sister.  Even as her lips briefly made contact with mine, I
found myself with my eyes still open.  Rather than being met with her usual
smirk and flirty glances, I was faced with a more vulnerable expression. 
Eyes closed, lips slightly pursed, and patiently waiting for me to decide
whether or not to meet her halfway.

   Honestly, this would have been a lot easier if she just fucking kissed
me.  Then I would have an excuse, and could blame her a lot more easily.  I
mean, she had laid out her intentions from the very beginning, even if I
hadn -(TM)t taken her seriously at the time.  This was all Natalie. 
Flaunting her body,  -~innocently -(TM) teasing me with her words and her
actions, and now putting her hands on me and setting us up for a kiss.  But
now, she was waiting.  Just like I had given in and asked her to take off
my shirt, I was going to have to cave for this and be culpable as well.

   Looking at her was too tempting.  Too many similar features to Jessica
and, admittedly, Natalie currently had that softly intimate look that would
make just about any guy melt.  The most appropriate and faithful thing to
do, of course, would be to step back and walk away.  Instead, I split the
difference and closed my own eyes.  Foolishly thinking that it would help,
that I -(TM)d find some clarity by blacking out the image that was giving
me such pause.  Instead, it only drew attention to all the physical
sensations I had only peripherally been aware of so far.

   Natalie -(TM)s hands, on my now bare sides.  They were never fully
still; her fingers idly traced up and down, reminding me of their presence,
alternating with a small circle or two of her thumbs every now and then.  I
could also distinctly feel both of her breasts as they pressed against me,
soft yet firm enough to make out her smaller form even through the pink
bikini.  And finally, her lips.  Not just their proximity, the way that she
brushed them against mine a second time in an attempt to encourage me to
close the rest of the distance, but also the way her warm breath washed
over my own lips.

   Fuck.

    -�Natalie, we shouldn -(TM)t, -� I whispered.  The words were more for
me than they were for her.  Clearly she had no shame when it came to doing
something like this.  Was this a habit of hers?  Did she make a sport out
of trying out her sister -(TM)s boyfriends?  I wasn -(TM)t vain enough to
believe that I was somehow special enough to draw her eye after all of two
seconds, but this could also be a new venture of hers for all I knew.

   And did it matter?  Right now, it was me and her.  It was difficult to
think about the rest of the world when I was wrapped up in Natalie -(TM)s
warmth and tempting touch.

    -�It -(TM)s just a kiss, -� she quietly replied,  -�It doesn -(TM)t
mean anything.  You don -(TM)t like me, do you? -�

   No, not really.  I mean, we literally just met.  Every second of silence
that passed after her question, however, could have implied the opposite.
So without thinking much about where she might be taking this, I said, 
-�No.  I like Jessica. -� Once again, more for myself.  While it felt like
we had already crossed a line, there was still time to tap the brakes. 
Except everything she was doing felt so good, and it would be so easy to
just go for it.  Clearly she wanted it.  And it -(TM)s not like I didn
-(TM)t want it.

   It was just, well, wrong.  She was my girlfriend -(TM)s sister.  And,
even though she was eighteen, she was also in fucking high school.  Wrong.
Wrong, wrong, wrong.

    -�So, what -(TM)s the harm? -� Natalie shifted her weight, pressing a
little further into me and settling her lips against mine.  Still not
kissing me, but positioning herself in a way where I physically felt each
word she formed.   -�No feelings.  No pressure.  Just fun. -�

   What, friends with benefits?  In the most taboo fashion possible?  
-�Natalie- -� I began, but had no idea how to continue.  Especially when
talking on my own just drew further attention to how our lips were almost
fully pressed together without actually kissing.  The way her boobs were
pushing into my chest caused another twitch below my waist, and it took a
bit of willpower to stop that from turning into something more.  The last
thing I needed was for Natalie to have undeniable proof that she was having
an effect on me, though the fact that we were still here like this was
probably enough of an indication.

    -�Hmm? -� she responded.  Humming into my lips and slightly parting her
own, she softly sighed,  -�Come on, babe.  I know you want me. -�

   She wasn -(TM)t wrong.

    -�It doesn -(TM)t mean anything? -� I asked.  One more time.  I needed
to hear it one more time, before giving into my desires.  Ironically
needing validation from the very girl who would have no problem saying just
about anything to make this happen.

    -�Of course not, -� she said.  Even when Natalie -(TM)s voice was
little more than a whisper, the lilting tone was still there.  But now that
we were here, now that we were so close to doing something that was wrong
in so many ways, the girl -(TM)s voice was a lot more seductive than it was
flirty.   -�And no one has to know. -�

    -�No one has to know . . . -� I echoed.

   As in, not Jessica.  But as I teetered over the edge, taunted and baited
and strung along by the cute bombshell before me, it was getting more and
more difficult to think about my girlfriend.  She wasn -(TM)t here right
now.  But Natalie was, and she was right.  I wanted her.

   Unable to resist any longer, I went for it.



   Part Ten

   My first kiss with Jessica had been tame.

   It was one of those  -~first date -(TM) kisses you share at the end of
the night; a peck to affirm that you both had a good time.  Not that I
would have been opposed to something more, of course, but I usually aimed
for the more patient and respectful route to play things safe and not push
my luck.  If a girl wanted more than that at the end of the night, she
usually wasn -(TM)t shy about communicating as much.

   Natalie was nothing like her older sister.  After so much suspense, it
was like a dam had broken.  Instead of water, however, it was sheer
passion. Our lips crashed together, and all bets were off as she locked
hers with mine.  So far, I had managed to keep my hands to myself, though
they had reflexively moved towards her once or twice throughout the last
few minutes of teasing.  As we began making out, I could no longer hold
myself back.  Matching the intensity of her kiss, I gripped her bare sides
just underneath her bikini top.

   Once I was there, I discovered that it wasn -(TM)t good enough.  Her
skin was so smooth and inviting, and I wanted more of Natalie -(TM)s
tempting body as she both pulled me into her and pressed herself against me
at the same time.  My hands shifted until my arms were wrapped around her.
One hand held her upper back, ready to untie the strings of her bikini at a
moment -(TM)s notice; the other hand rested on her lower back, poised to
reach lower.  Our bodies were pretty flush already, but I made a point to
match her energy and pull her even closer.

   I was rewarded with a hum against my lips.  It was the lightest little
moan, but the way I could feel it through our connection was wildly
arousing.  Natalie was also a really good kisser.  She had told me as much,
of course, but experiencing it was a lot different than the fleeting
image/fantasy her words had created earlier.  Normally making out with
someone for the first time required some degree of adjustment as you got
used to their lips and their style.  Not with Natalie.  She seemed to fit
against me perfectly, and there was never an awkward moment as our lips met
again and again.  Even the small breaks were sexy.  After a deep kiss, she
would round it off with a light nibble, or a playful lick, or a sultry
sigh. The girl -(TM)s warm breath against my lips was as intoxicating as
all the physical sensations.  Anything and everything she did sparked more
passion and lust from me, and I continued the hot make-out session with her
without any reservations.

   Just like my hands were more or less acting of my own accord, the twitch
or two below my waist from before was developing into a more noticeable
hardness that wasn -(TM)t going to go away any time soon.  Especially not
after Natalie noticed.  It wasn -(TM)t just her chest that was pressed
against me; the moment she felt my member shift between us, she gently
grinded her hips in a way that instantly coaxed me to full attention.

    -�Mmm, -� she purred against my lips.  Her hands trailed from my sides
to my waist, and she slightly separated herself from me; just enough so her
fingers could begin toying with the button of my jeans, but not undoing it.
At least, not undoing it yet.  She just found a good grip and gave a small
tug to further announce her presence.   -�Ask, babe, -� Natalie whispered.

   I knew what she wanted to hear.  It was the same as before, only this
time I didn -(TM)t hesitate in the slightest to go along with it.   -�Strip
me. -� My voice was just as quiet, as we spoke to each other without
separating our lips.  Deep down, I knew that this was wrong.  I was making
out with my girlfriend -(TM)s sister.  A fucking eighteen year old
finishing up her last semester of high school.  But Natalie was right -"I
wanted her.  And the further we went, the more difficult it was to think
clearly.  Wanting something and taking it were two different things
entirely, but we had long since crossed that line.

    -�Strip me, what? -� she asked.  Her hands stopped their idle
movements. They simply rested in place, and I immediately picked up on the
teasing threat.  If I didn -(TM)t play along, this could all easily stop.

    -�Strip me, please, -� I said, without missing a beat.

   A second later, I could actually feel her smirking against my lips.  
-�Close, -� she replied.  Her lips sank into mine for a long, almost
intimate kiss.  One hand kept its grip on the waistband of my jeans, while
the other roamed downwards, inch by inch.  With the lightest touch, she
grazed her fingertips against the tip of my shift.  The fact that I was
wearing clothes made it even more of a tease; as I could barely appreciate
the feeling with the layers in the way.   -�Strip me, Natalie, -� she
corrected me.

   I could hardly stop my body from reacting.  My hips shifted forward,
trying to meet her hand for a more satisfying touch than the first one.  No
luck.  For every bit I moved towards her, Natalie drew her hand that much
farther away.  It was always within reach, always brushing against the
sensitive spot it had found, but never enough for me to get anything from
it.   -�Fuck you. -� I knew exactly what she was doing, but felt powerless
to stop it.  This was her game, and I was just along for the ride.  Of
course, that didn -(TM)t mean I couldn -(TM)t call her out on things.

    -�Soon, babe.  You can fuck me in a minute. -� Her flirty tone was
back, lilting and dripping with seductive confidence.   -�But first, say
the magic words. -�

   The way she twisted my words should have been frustrating, but I could
only think about how hot it sounded in her voice.  Not wasting a second, I
locked lips with her to show that I could be assertive, too.  Then, I
murmured the phrase from earlier.

    -�Please strip me, Natalie. -�



   Part Eleven

    -�With pleasure. -�

   We were too close together for me to actually see the smirk, but I could
practically sense it based on her tone.  I felt another light stroke of her
fingertips over my jeans, and foolishly took the bait and tried to shift my
hips forward like before.  Once again, I was denied; Natalie -(TM)s hand
retreated upwards this time, to meet her other hand at the button of my
jeans.  She didn -(TM)t tease me this time around, however, and wasted no
time in undoing it.

   I was in too deep at this point to slow down, and found my own hand
pulling on the string of her bikini top to undo the loose knot.  Last time,
I had averted my gaze when she had been dangerously close to revealing her
chest.  Now that we were here and my brain was doing less of the thinking,
however, I was determined to see what Natalie looked like topless.  The
fucked up part was, a part of me was interested in comparing her to
Jessica.

   Instead of stripping each other during a passionate kiss, this was more
like a neverending moment of suspense.  Inch by inch, Natalie lowered my
zipper and I finished untying her pink top.  Our lips brushed a few times,
breaths mingling as we stood intimately close to each other.  It was like
we were daring each other to make the first move.

   Once my jeans were properly loosened, Natalie -(TM)s hands trailed up to
grip the waistband on opposite sides.  There was something about the way
she never broke contact that was subtly arousing, which just added to
everything else she had done to ensure I was thoroughly lusting after her.
I paired my upward movements with her own, tracing the smooth skin of her
upper back with my fingers until I could untie the second set of strings
still gently knotted on her neck.  She must have rushed the job when
Jessica arrived downstairs earlier, as it barely took one tug for the
strings to become undone.

   The bikini top fell to the floor between us, and Natalie was quick to
step forward and press her bare breasts against me.  Shifting her head
forward, she pressed her lips to my ear.  Just like how we just were, there
was a long moment of silence and stillness as I took in all the points of
contact.  Her hands, on my hips.  Boobs, against my bare chest.  Soft
breathing, which I could feel both from the proximity of her lips and the
way her chest slightly rose and fell against mine.

   She finally broke the spell with a light nibble and a sultry sigh.  
-�Do you want to fuck me? -� she whispered.

   There was only one answer.   -�Yes. -� My hands trailed back down from
her neck until I was holding her bare sides.  I wanted to explore her
chest, to see just how those small, perky breasts felt in my hands, but had
to settle on my palms resting on their sides for now.  Due to the way our
heads were positioned, I was fairly close to Natalie -(TM)s ear as well,
and guessed that she might want to hear some more  -~magic words -(TM) to
keep this going.   -�I want to fuck you, Natalie. -�

    -�Good boy. -� The same  -~praise -(TM) from earlier.  She said it so
casually, yet it struck even more of a chord when murmured in my ear. 
Taking a second to make sure she had a good grip on both pants and my
underwear, Natalie gave a small downward tug.  Little by little, teasing as
ever, the cocky girl pulled my clothes down until she succeeded in freeing
my dick that was thoroughly hard from everything she was throwing at me.  
-�You know, -� Natalie said.  Apparently deciding that she had stripped me
enough for the time being, she softly wrapped one hand around my exposed
shaft.  Without even a squeeze or a stroke, it was enough to make my member
pulse and maintain a full erection from her touch,  -�It -(TM)s not too
late to call this off.  I mean, I am your girlfriend -(TM)s little sister.
That doesn -(TM)t bother you? -�

   Fucking BRAT.

   Of course I knew that.  It was a much bigger hang-up than her age, since
knowing she was eighteen and just a year younger than me offset the fact
that she wasn -(TM)t due to graduate for another couple months.  Cheating
was harder to justify, particularly considering who I was doing it with. 
And just when those thoughts had come close to disappearing into the depths
of my mind, Natalie brought them right back to the surface.  The shameless
girl had waited until we were both nearly naked, until my cock was in her
fucking hand.

   A part of me was tempted to push her away.  Less because of my need to
be faithful to Jessica, and more to keep Natalie from getting what she
wanted.  But I couldn -(TM)t.  I knew exactly what she was doing, but I was
too hot for her to stop it.  Of course, it did bother me on some level. 
She probably knew so, but I still wasn -(TM)t going to give her the
satisfaction of saying it out loud.   -�It doesn -(TM)t mean anything, -� I
muttered.  Her words.

    -�No one has to know, -� she replied.  The other little mantra she had
coined a few minutes ago.  Only this time, it came with a condition.   -�IF
you do a little something for me. -�

   Whatever resolve I had in terms of pushing back against the girl -(TM)s
games, more in the name of ruining a bit of her fun rather than actually
trying to get myself out of this fucked up mess, instantly crumbled when
she lightly squeezed while simultaneously sighing a borderline moan right
into my ear.

    -�. . .  What do you want? -� I hesitantly asked.

    -�Nothing you can -(TM)t handle, babe, -� she said.  Pulling back so
she could meet my eyes, while keeping us positioned just how we were, she
gazed up at me with a seductive smirk.   -�I want to hear the words.  Tell
me exactly who you want to fuck. -�
