 ï>¿Little Sister's Amazing Underboob by IronBuddah

   Chapter 14: Eating at Home

   My cock was absolutely raging.  For one thing, it had been thirty hours
since I had last had sex with my sister on the floor of the van at the end
of the camping trip.  For another, as I was walking home from the bus stop,
Tanya had sent me a text saying,  -œCome to my room when you get home. -

   I dropped my backpack at the door, went up the stairs two at a time, and
burst into my sister -(TM)s room without knocking.  Tanya was standing up
waiting for me wearing nothing but the little crop top which had caused me
to ask to touch her tits.  It was hard to believe that started us down the
path of becoming sibling lovers two days ago.  My cock nearly erupted in my
pants.   -œDamn sis!  You need to warn me before you surprise me looking
like that.  I nearly lost a load just from looking at you. -

    -œAhh, and here I was ready to blow you. -

    -œI said almost... - I trailed off as I started feeling my sister up
under her shirt as I stared longingly at her pussy.

    -œMmm, your hands feel even better than ever Mike.  How do you keep
managing that? -

    -œI don -(TM)t know, - I mumbled.  I guided Tanya to her bed, and she
sat down on it.  I undid my pants and dropped them to my ankles.  I tried
to line up my cock for more sex with my sister.

    -œWhoa, I -(TM)m way too sore for that today!  Every time I stood up or
sat down at school today, I was thinking I had way too much fun over the
weekend.  I felt like I was wincing every time I did that and hoping no one
noticed I was moving kind of gingerly. -

    -œAh sis, I know it -(TM)s only been a little over a day, but I -(TM)m
going crazy for more of your sweet pussy wrapped around my cock! -

    -œHey, I -(TM)m going to take care of you; you heard me say I planned
on blowing you, right?  You still like blow jobs, don -(TM)t you? -

   I hadn -(TM)t been able to tear my gaze away from between Tanya -(TM)s
legs during any of this,  -œI -(TM)m so hungry for your cunt! - I blurted
out.  Still staring at her plump pussy lips I added,  -œWould you be up for
trying a different sort of oral? -

    -œAre you offering to... - Tanya didn -(TM)t finish her question.

    -œYeah!  I want to eat my little sister -(TM)s pussy! - I was so
excited, and I found my mouth was watering.  I dropped down to my knees,
licking my lips as I prepared to go down on Tanya.

    -œWait, I forgot to set a timer! -

   I was confused,  -œHey, you -(TM)re not putting time limits on what I
get to do with you again, are you? -

    -œOnly out of necessity; Mom will be home soon.  We can -(TM)t afford
to let her catch us doing any sort of oral sex. -

    -œOh shit, I completely forgot about our parents when I saw the way you
were dressed and waiting for me. -

    -œDamn it Mike!  I can -(TM)t be the only one of us trying not to get
caught by our parents ...  ieee! -

   I knew Tanya was right to scold me, but it wasn -(TM)t really
penetrating into my brain.  I kissed my sister -(TM)s snatch, causing her
to squeal with delight.   -œCan only think ...  about pussy, - I mumbled
before diving down between my sister -(TM)s legs to explore more earnestly.
Honestly, I didn -(TM)t know what to do, she seemed to like the kissing
well enough, but from porn it seemed like guys used their tongue on a woman
a lot.  So I tried licking up one of Tanya -(TM)s plump lips and down the
other.  That elicited another squeal of delight and I realized that her
pussy was slowly opening up as I licked at it.

   Tanya reached her hand between her legs and actually opened her pussy
further.   -œLick inside; don -(TM)t rush past the clit! -

   Now I could see my sister -(TM)s clit sitting at the top of her pussy. I
devoted all my attention to it, licking at it with the flicking motion I
had seen in porn videos.   -œAhh, ahh, ahh, ieeeee!  Stop!  Mike, stop! -

   I think Tanya almost came from the sudden lack of sensation.  When she
spoke again she told me,  -œI said don -(TM)t rush past the clit, not
tongue lash it into oblivion!  It -(TM)s too sensitive for constant
attention.  I mean, give it some love, but before I get over stimulated
move on to other parts of my pussy.  Trust me, I -(TM)m sensitive
everywhere down there.

   I started licking again at the insides of my sister -(TM)s pink folds,
and I believed her claim that everything in her pussy had the potential to
feel good to her.  I also discovered that I loved the way Tanya tasted.  I
found that my licking was starting to be for the purposes of lapping up
more and more of her delicious pussy juice than any planned strategy of
where to put my tongue.  After realizing this, I directed my attention back
to her clit.   -œAhh, ahh, ahh... - This time however, I went back to
lapping up Tanya -(TM)s juices before she got to the state she described as
over stimulated.  That seemed to work really well.  I alternated between
the inside of Tanya -(TM)s snatch and lavishing attention on her clit.  The
more I ate her, the longer I found I could flick her clit with my tongue
before her cries of pleasure changed to those of protest.

   Then the timer on Tanya -(TM)s cell phone started going off.  Fuck!

   Tanya was equally frustrated,  -œFuck, I don -(TM)t want to stop!  Mom
-(TM)s not home yet.  Keep going! -

    -œAre you sure? - For an answer, Tanya grabbed my head with both hands
and held it between her legs.  Now she was the one guiding me between her
clit and the slightly less sensitive lower areas of her pussy.  At some
point I realized that she had been directing my attention to her clit for
some time now, so I made an effort to really move my tongue quickly over
the sensitive little nub.  It really drove my sister wild.  She bucked me
off her pussy and grasped the bed sheets writing in pleasure.  The little
crop top she had been wearing had shifted up to bare her breasts, and I
watched with delight as her large mounds wobbled on her chest as her body
shook from side to side.

    -œDamn it big brother, that was amazing!  I didn -(TM)t know I could
cum so hard! -

    -œI love eating your pussy sis!  You are so delicious! - Before I
could say more, we heard a door open.  Our mother was home.

   Starting on the 1st of three extension chapters for this story.  None of
them are huge, so look for the next instalments to be posted soon.



   Chapter 15: Tanya Needs the D

   Tanya looked really frustrated, and grabbed at her bed sheets again. 
This time she wasn -(TM)t cumming though; it was pure irritation that we
weren -(TM)t alone in the house any longer.  What Tanya said next nearly
got us busted.  It was such a soft whisper, I could barely here her saying,
 -œFuck, I need the D! -

    -œI thought you were too sore for that? - I whispered back.

    -œI probably am, but after the way you ate my pussy I want it anyway!
-

    -œOK, - I responded as I guided my aching hard on to my sisters belly,
and sighed as I started to sink into her sopping wet pussy.  She must have
really cum hard, because I had been doing my best to drink up all of her
pussy juice earlier.  However, her pussy had never felt wetter to me.

   Tanya sighed too as her body responded to my cock eagerly, but by the
time I was half way inside her, she was saying,  -œNo, Mike, no!  Not like
this.  Mom will hear us!! -

   I stopped moving my cock deeper into Tanya -(TM)s body, but I didn
-(TM)t pull it out.  After eating her pussy, it felt so good to be inside
Tanya again.   -œDon -(TM)t want to stop! -

   Tanya couldn -(TM)t control herself either lifting her hips off the bed
and pushing her pussy most of the way up my shaft.  She panted,  -œI don
-(TM)t either, but if we do it this way Mom -(TM)s going to catch us going
at it. -

   That finally got me to pull my aching cock out of my sister -(TM)s body
with an obscene pop.   -œWhat are we going to do? -

    -œJust a second, we have to make sure we don -(TM)t make lots of noise.
- Tanya tried to get over to her dresser, but her legs buckled before she
had taken a single step.   -œFuck, Mike!  What did you do to me when you
ate my pussy?  My legs are like jelly. -

    -œI guess we don -(TM)t have to finish, - I said reluctantly.

    -œAre you insane?  If you don -(TM)t do something to put out the fire
you lit between my legs I -(TM)m likely to strip naked and finger myself at
the dinner table.  And we -(TM)ve got the more obvious problem of you
walking around with a big boner all night. -

   I went over to Tanya -(TM)s dresser with my hard cock bobbing and asked,
 -œWhat am I looking for? -

    -œFind a pair of my socks.  Put one in your mouth and give me the
other. - Tanya got flat on her back in the middle of her bedroom floor as
she said this.

    -œShouldn -(TM)t you be on top?  You were really good about not getting
us caught when we were in the van. -

    -œProbably, - Tanya admitted,  -œBut after the way you ate my pussy,
even as sore as I am, the only thing I can think about is you on top of me
fucking me however you want! -

   My sister -(TM)s words sent a thrill of pleasure through my whole body,
but I especially felt it in my cock.  It had to be inside Tanya again, and
quickly.  Honestly, I had already mostly forgotten the fear of discovery,
and I wasn -(TM)t sure how I had managed to pull my aching cock from Tanya
-(TM)s pussy when she had been sitting on the bed.  I stuffed the sock in
my mouth, more because that -(TM)s what Tanya told me I needed to do if I
wanted to have sex with her than from any realization that it would keep me
from yelling out, and got into position to fuck my sister again.  My dick
actually started to tingle I was so eager to get it back inside Tanya as I
tossed her the other sock.

   If fact, I couldn -(TM)t make myself wait to start fucking again.  Tanya
moaned,  -œMik ...  mmmph - as she quickly stuffed the sock in her mouth
in response to me stuffing her pussy full of my cock.  At first I was
sliding it gently in and out of Tanya -(TM)s body.  It was more from my
cock being sore than remembering Tanya -(TM)s multiple comments about how
sore her own pussy was.  However, the sight of my little sister on her
back, in the floor of her room, with her tits half hanging out and my dick
splitting her pussy lips was inspiring me to fuck her faster and faster. 
The harder I plowed into Tanya -(TM)s body, the more wildly her boobs
bounced, and that just made me want to fuck her faster still.  Before I
knew it, we were both breathing hard through our noses, almost snorting
since we had socks in our mouths to keep us quiet.

   I could tell from Tanya -(TM)s face that this was hurting, but she
wrapped her legs around me and held me so tight that there was no chance my
dick might slide free of her pussy as we fucked.  My cock was hurting too,
but the only thing going through my brain was the work  -~fuck -(TM).  It
repeated over and over as I continued to thrust hard into my sister -(TM)s
body.  My little sister had said she needed my dick, and my only purpose in
life was to give it to her!

   Of course, fucking hard and fast like that can -(TM)t last forever,
especially with a babe as sexy as Tanya!  I had no concept of how long we
had been going at it after hearing our Mom arrive home, but it was long
enough that first one, then both tits bounced free of the crop top, and of
course I started pounding my dick into Tanya -(TM)s snatch harder each time
one of her big boobs came into view.  Some time after that, I got
goosebumps on my arms, then my cock exploded jizz into Tanya -(TM)s belly.
I froze, and my little sister started milking my cock for every drop of
spunk I had by tensing and relaxing muscles inside her pussy.  The feeling
of me ejaculating inside her seemed to do something to her because her face
relaxed, and she pulled the sock from her mouth to let out a long contented
sigh.

   I pulled the sock out of my mouth too, and said,  -œI hope that wasn
-(TM)t too rough; I know you said you were sore, but once we got going, I
couldn -(TM)t control myself. -

    -œIt was strange, even though it was hurting me, that just made me need
it more.  Like I said, I -(TM)m going to have to be careful about letting
you eat me out.  That is way too good and seems to have side effects I can
-(TM)t control. -

    -œI loved lapping at your pussy with my tongue, I can -(TM)t wait to
eat you out again! -

    -œI can -(TM)t either, - Tanya admitted.   -œBut like I said, we have
to be careful.  Letting you eat my pussy seems to make me even dumber than
a boy with a hard on. -

    -œBut did I do a good job of putting out the fire between your legs
that my tongue started? -

    -œYou did a very good job big brother!  I needed that cock of yours and
you didn -(TM)t hold anything back! -



   Chapter 16: Mysterious Errand

   In the six weeks since our camping trip, Tanya and I weren -(TM)t able
to keep up the insane amount of sex we had managed those first few days. 
However, we were still averaging better than sex once a day.  Throw in a
few blow jobs a week, and Tanya was consistently getting me off an average
of twice a day.  We were more cautious when it came to me eating Tanya out.
Every time I ate my sister -(TM)s pussy, it had a stronger and stronger
effect on her.  I guess I was getting better at it.  However, since Tanya
was the one we counted on to keep our parents from noticing that we were
having sex with each other, we couldn -(TM)t risk Tanya going mad with the
need for my cock.  Now, just because we were averaging having sex with each
other better than once a day, there were still days when we couldn -(TM)t
manage to hook up safely.  That always made the next day a little dicey as
we were both insanely horny after a dry day and weren -(TM)t necessarily as
cautious as we should have been.  Thankfully, we had managed to get through
those desperate days safely.

   Weekends were the least predictable.  Twice, we got long blocks of time
together and we were able to enjoy each other -(TM)s bodies multiple times
and in whatever way we wanted.  Twice we couldn -(TM)t manage to get away
from our parents at all.  There was nothing to do but wait until we got
home from school on Monday.  After two days without sex, we pretty much
attacked each other as soon as we got home.  On both occasions, we started
screwing in the living room, and barely managed to get all our discarded
clothing picked up and the two of us back to one of our bedrooms before
either of our parents got home.  We still weren -(TM)t out of the woods,
because after two days without relief, we kept fooling around until we were
called down to dinner.

   I was trying to figure out what my prospects with Tanya were this
weekend when Mom told me that she and Dad were going out to run errands. 
That came with the instructions that we would be going out to eat as a
family, so Tanya and I shouldn -(TM)t make any plans with our friends.  Of
course, any time I heard I would be alone in the house with Tanya, I
started to get excited.  Hopefully Mom would never guess that I would
always pick being home alone with my sister over going over to a friend
-(TM)s house.  As soon as our parents drove away, I went up to knock on
Tanya -(TM)s door,  -œHey, did you hear that Mom & Dad are running errands
and want us to stay put around the house.  Like we -(TM)d waste prime
incest time by doing something with our friends. -

    -œYeah, Mom was all mysterious about what she and Dad were doing when
she told me.  Don -(TM)t come in yet; I -(TM)ve got a surprise for you. -

   Tanya had a surprise for me?  Now I was really excited.  I stripped
naked, my cock hard and throbbing in eagerness for my sister, and tossed my
clothes in my room as I waited to see whatever surprise Tanya had in store
for me.  My eyes nearly popped out of my head when Tanya let me open the
door to her room.  She was wearing a blue nightie with matching panties,
but what really caught my eye was that the nightie was almost completely
see through from just below her nipples down to her belly button.  It
reminded me of what she had worn on the camping trip that had started us
down this path of sibling love.  In short, I loved it.

    -œMike, I -(TM)m supposed to be surprising you, not you surprising me
by showing up in my room naked.  Well, don -(TM)t just stand there staring;
let me know if you like it. -

    -œFuck!  I love it.  Let me show you want it makes me want to do! - I
got in bed with Tanya and straddled her torso.  Then I lifted up the
nightie and pressed my cock against her belly before guiding it between her
breasts.  It was awesome; I could see my cock disappearing between the
undersides of my sister -(TM)s tits before it was hidden behind the non see
through part of her nightie.  Then I could see the head peaking out at the
top of her cleavage as I finished my thrusting.  Then I grabbed Tanya
-(TM)s tits and massaged my cock with her round mounds as I fucked her
knockers.   -œDamn, I -(TM)ve wanted to do this ever since I saw you in
that crop top on the trail. -

    -œWell, if you wanted to fuck my tits so badly, why didn -(TM)t you
just say so any time in the past six weeks? -

    -œOh, I thought you would think I was weird.  And then there was all
the normal sex and blow jobs too. -

    -œLike I don -(TM)t already think you -(TM)re weird, - Tanya teased. 
-œI have to say though, I didn -(TM)t think I -(TM)d get anything out of a
tit fuck, but it -(TM)s really getting me hot and bothered big brother! -

    -œYou think you -(TM)re hot and bothered, - I panted.   -œIf you don
-(TM)t want to get stains on the nightie, we need to stop. -

    -œI -(TM)d love it if you stained this top with your seed! - was Tanya
-(TM)s reply.

   Hearing Tanya refer to my jizz as seed totally sent me over the top.  I
came so hard that more of my spunk ended up on Tanya -(TM)s face and in her
hair than on the nightie itself.   -œFuck that was intense, - I moaned as
I milked my shaft of any remaining cum with Tanya -(TM)s big tits after my
orgasm was complete.

    -œUgh, now I want to get off, but it -(TM)s going to take a while to
recharge your cock, - Tanya grunted as she arched her back.

    -œHey, Mom and Dad said they would be gone for a while, I can always
eat your pussy if you want to get off right away. -

    -œYes, yes!  Eat me big brother.  Make your little sister cum over and
over! -

   I did just that, eating Tanya to three big orgasms in a row.  I was
going to have to keep in mind that fucking her tits drove her wild in this
way.  I had loved that and definitely wanted to spend more time with my
cock trapped in the space between her two big jugs.  After her third
orgasm, I didn -(TM)t wait for any sort of declaration from Tanya that she
wanted my cock.  I was hard again, and I just wanted it in her pussy. 
After eating her three times, I was almost instantly ready to cum again in
spite of starting everything off with a tit fuck.

    -œDamn Tanya, your pussy is so hot and wet after I ate you.  I -(TM)m
not going to be able to last long. -

    -œJust last as long as you -(TM)re able, and don -(TM)t pull out after
you cum.  And tell me how much you love me! -

    -œOh, I love you so much Tanya.  You -(TM)re the best little sister in
the world.  I love that you let me put my dick inside you ...  and ...  uh
...  cum ...  ugh ...  ugh ...  so much ...  ugh! -

   I put my forehead on Tanya -(TM)s while I was making my declaration of
incestuous love to her and stayed there sighing in post orgasmic pleasure
after my second cum of the afternoon had been deposited deep in her pussy.
-œAnd you -(TM)re the best big brother in the world for the way you eat and
fuck me, - Tanya told me while we stared into each other -(TM)s eyes.

    -œHow did you even get that lingerie?  There -(TM)s no way Mom or Dad
would pay for that, - I asked after a few minutes of silence.

    -œIt helps when you -(TM)re both busty and skinny.  I told mom I needed
to custom order a bra, but this is what I ordered instead. -

    -œWow Tanya, you -(TM)re an absolute genius. -

   I didn -(TM)t try to work my way into a second screw with Tanya
immediately.  We just enjoyed cuddling together with my cock still in her
pussy.  At some point I must have moved from my position on top of Tanya
then fallen asleep.  The next thing I knew, I was waking up with a half
hard dick trapped between Tanya -(TM)s thighs as I was spooning her still
in her bed.  I reached between my sister -(TM)s legs as my cock was rapidly
becoming harder.  I guided it to her pussy, and gently managed to work it
inside her.  Then I started slowly screwing my cock in and out.  Tanya must
have fallen asleep too, because I felt her shift positions slightly, and
she purred,  -œThat -(TM)s a nice way to wake me up Mike.  Go slow until we
make sure Mom and Dad haven -(TM)t returned home. -

   I started slow like Tanya told me, enjoying the feeling of dragging my
cock lazily in and out of her pussy while I felt her boobs through the
transparent portion of the nightie.  I could feel a stiff spot where my
jizz had dried while we slept.  We hadn -(TM)t heard any noises from
downstairs, so Tanya didn -(TM)t caution me as every squeeze of her tits
caused me to fuck her harder and faster.  Before I knew it, her bed springs
were creaking wildly even from this position and I was grunting with
passion.  Tanya was yelling for me to fuck her harder and faster.  I closed
my eyes and enjoyed fucking my sister -(TM)s body purely by feel.  I didn
-(TM)t know what had happened when Tanya froze and whispered,  -œOh no, oh
fuck no! -

   Then my blood ran cold when I heard my father speak,  -œDamn it!  Are we
going to need a tee shirt for you too Tanya? -

   I was too scared to open my eyes, but I couldn -(TM)t bring myself to
pull my dick out of my sister since this might be my last chance to enjoy
her pussy.  I heard my Mom say,  -œIt -(TM)s OK, she -(TM)s on the pill. -

    -œIt -(TM)s OK?  How can this possibly be OK and why is Tanya on the
pill?  Did you know about this? -

    -œWell, it -(TM)s a female thing.  It -(TM)s not OK, OK, but not
worried about Tanya getting knocked up OK if you know what I mean. 
Finally, of course I didn -(TM)t know about any of this! -

   I risked opening my eyes a bit to try to gauge how upset our parents
were, but what I noticed first was Mom -(TM)s shirt which said  -œBaby On
Board - over her belly.  Dad had done it, he had knocked Mom up!  Despite
getting caught red handed, this knowledge pushed me over the edge and I
grunted lewdly as I started thrusting hard into Tanya -(TM)s pussy again as
our parents watched.   -œFuck, I need to cum! -

    -œI -(TM)m going to kill that boy! - Dad threatened.

   However, Tanya immediately pleaded,  -œDon -(TM)t hurt him Daddy! -

   My need for my sister -(TM)s sexy body proved stronger than any sort of
self preservation.   -œI -(TM)m gonna cum; I -(TM)m gonna cum! - I
announced for the room as I continued to pound Tanya -(TM)s pussy.   -œUgh!
Cumming, cumming! - Only after releasing another load of jizz into Tanya
-(TM)s pussy, did I finally shut up and pull my cock out of Tanya with an
obscene pop that made my mother -(TM)s eyebrows shoot up and my father
-(TM)s face look even angrier.  I was pretty sure I was a dead man.

   Instead of threatening me with death again, Dad said,  -œYou two have
one minute to be dressed and downstairs to explain yourselves! -



   Epilogue

   Dad exploded with rage when Tanya went downstairs without me, but she
was genuinely afraid for me and wouldn -(TM)t let me go down with her.  I
could hear everything, but I didn -(TM)t dare make a peep.  Mom calmly
questioned Tanya on all manner of things while Dad remained silent.  That
terrified me all the more.  I didn -(TM)t start to relax until Tanya
explained that we had heard them having sex on the camping trip.  Somehow
they got the idea that was the moment we started doing incest together. 
For some reason, they seemed less inclined to kill me or ship me off to
military school at this point, so Tanya didn -(TM)t correct their
interpretation of events that led to us becoming lovers.  I didn -(TM)t
understand it at first, but they somehow blamed themselves for Tanya and I
having sex somehow feeling they had caused it when we overheard them trying
to make a baby in the tent.

   The other thing that worked in my favor was Tanya saying we really loved
each other and that it wasn -(TM)t my fault that things had gotten this far
between us, it was hers.  When I thought about it, I had started things
with my obscene request to touch my own sister -(TM)s tits.  However, after
that, she really had been an eager participant as we experimented further
and further with incest.

   Mom and Dad still weren -(TM)t happy with us, but in the end, they didn
-(TM)t try to make us stop sleeping together either.  Now, we couldn -(TM)t
throw it in their faces, in fact, if they caught us even kissing, we got
grounded for a day.  The more they caught us doing, the longer we were
grounded.  The worst was one night when Tanya snuck into my room and we
were a little too noisy and got caught actually fucking again.  We did get
grounded a few times, and then they really did watch us like hawks.  That
was absolute torture to go several days without any sort of contact with
each other, let alone sex.  We could hardly bear that, so we were pretty
good about not getting caught, especially after being grounded and
miserable a few times.

   Anyway, that -(TM)s the story of how our mother spraining her ankle led
to my sister and I becoming incestuous lovers.
