   Beth Ann sighed and wiped the long counter of the Hamilton Dry Goods
store.  Jake, her brother, was doing it again.  He was in the back room
jacking off, while she stayed out front tending the counter, not three feet
away.  As she wiped the counter, probably for the ten thousandth time, she
could hear the rhythmic slap of his hand on his big angry looking boner -
also probably for the ten thousandth time, she thought glumly.

   Would you hurry up, you pervert?" she hissed through the saloon doors
that went to the back room.  "I've got to pee!"

   "Well then" he panted.  "Go ahead and pee."

   "You know I can't leave the front unattended.  Aunt June would have a
fit if somebody came in and there wasn't a Hamilton right there to do their
every bidding."

   Beth Ann and Jake lived with their elderly Aunt and had for the last ten
years, ever since their parents were killed in an accident.  Aunt June was
the only family they had and, while she'd felt it was her duty to take them
in, she was also glad for the help they gave her in running her store.  The
fact that the store was out in the middle of Catlin County, thirty miles
from just about anywhere, didn't mean business was slow.  After all,
everybody living within ten miles was also twenty miles from just about
anywhere.  So there was a fairly constant stream of folks coming in and
out. But to make any real money, the store needed to be open about sixteen
hours a day.  Aunt June handled things from morning until suppertime, but
after that Beth Ann and Jake looked after things until it was time to
close. At least that's what they'd been doing ever since they'd turned
twelve.  At first it had been a wild adventure for the twins - being in
charge of a whole store - but four years later Beth Ann felt like she could
go anywhere in the place and find anything they sold blindfolded, and
hopping on one leg.

   Beth Ann heard the combination sigh and groan she also knew very well.
Jake was cumming, squirting two or three long white ropes of semen out of
his penis and into a tissue.  Her nose caught the unique scent of his
sexual fluid.  That too was a smell she knew well.  She wondered if all
boys did that constantly, like her brother seemed to.

   She thought back to the first time she'd seen him doing it.

   Beth Ann had gone out to the storage shed to find a case of number six
nails and was lugging it back into the back door of the store.  She had the
heavy box balanced on her shoulder, so she had a hand free to open the
door. She knew Jake wouldn't be able to hear her from up front if she
knocked, and that's where Jake was.  Or at least that's where he was
supposed to be.

   But he wasn't.

   Instead, as she walked up the dim hallway toward the front of the store,
she saw Jake standing just inside the saloon doors, peeking out into the
front room.  His pants were on the floor in a puddle around his ankles. 
His hand was moving in what would be his lap, if he was sitting.  Beth Ann
hadn't understood at first.

   "Jake?  What are you doing?"

   He'd turned and she'd seen clearly just what he was doing.  They'd been
thirteen at the time, and she'd known about reproduction and all that, but
she'd never seen an erect penis until then.

   Her brother's was, unknown to her, a prime example of a man's cock.  It
was about eight inches long, with a slight bend up and to the left.  He was
uncircumcised, which meant he didn't need any lubrication to jack off, and
could do it anywhere, any time.  Being a teenager, he could produce several
ounces of semen several times a day.  He'd learned how to get that semen
out of his balls while taking a bath when he was twelve, and had been doing
that just about every day since then.  Especially when he saw Janet
Thompson, who had just been in the store, buying the last of the number six
nails for her father.

   Of course Beth Ann didn't know all that at that time.  All she'd known
was that her brother had his hand on a very stiff penis and was slicking it
back and forth in an almost professional manner.

   Or had been.

   When she announced her presence he'd jumped, then bent down and pulled
his pants back up as quick as he could.  He'd stammered out something about
"Just having to".  Beth Ann had been pretty much speechless for half an
hour, but eventually she'd confronted him about it.  As they'd always been
pretty close, Jake was actually able to explain about Janet, and what she
always did to him, and how he relieved the pressure.  Beth Ann knew what
that feeling was like.  There was one boy at school who, whenever he talked
to her, made her stomach feel funny in a way that she just couldn't make go
away.

   But she'd never masturbated.  She didn't even know how to begin.

   In the years that had followed that incident, Beth Ann had begun to
notice how girls affected her brother.  If a pretty girl came into the
store Beth Ann would surreptitiously peek at the front of her brother's
trousers.  More often than not a bulge would appear, like magic.  And, when
the girl had left, Jake would think up some reason why he had to go into
the back room, or out to the storage shed, or to the bathroom.  She
couldn't go spy on him, because someone always had to be at the counter,
but she was pretty sure she knew what he was doing.  He was always in a
great mood when he came back, with a big smile on his face.

   It just wasn't fair.  He got all the fun, while she just got frustrated.
She didn't have a nice hard penis to play with.  It had never occurred to
her to explore her own body, to find out what might feel nice.

   Things had progressed one warm evening when they were fifteen.  Sandra
Jones had come slinking into the store wearing a dress so old you could
almost see through it, and had asked for a twenty-four inch zipper for her
mother.  Jake had told her that he thought there might be one in a box up
in the attic and he'd have to show her.  It wasn't until after they'd
climbed up the fold down ladder to the loft that Beth Ann had suddenly
realized Jake hadn't been up in the attic for over a year, and wouldn't
have noticed anything at all about sewing notions even if he had.  AND,
he'd had another of those boners of his as he led Sandra to the stairs. 
Jake was doing something up there with Sandra, and Beth Ann wanted to know
what.

   So she peeked.  She quietly climbed up the ladder and carefully raised
her head into the open space above.  She almost fell off the ladder when
she realized what she was seeing.  Sandra was lying on the floor, the dress
up around her stomach.  Her legs were spread and Jake was between them. 
His pants were down around his ankles again and his pale white butt was
bobbing up and down while Sandra sighed with pleasure.  In the shaft of
light coming through a dusty window, Beth Ann could see his stiff penis
sliding in and out of Sandra's pussy.  Her own pussy clenched as she
stifled a gasp and she ducked her head back down instantly.  He was FUCKING
her!  Right there in the store!

   Beth Ann found she was panting, her breasts heaving like she'd run a
mile.  How could he do that right here in the store?  And why would Sandra
let him do that at all?

   Maybe he was raping her!  Maybe she needed help!

   Beth Ann peeked back over the edge of the floor.  Sandra was making
noise ...  moaning ...  was that pain?  Beth Ann examined the way Sandra
was lying.  Her legs were out flung, giving Jake plenty of room.  Her arms
were around him, not pushing him away.  Suddenly Sandra began thrusting her
pussy up at Jake as he pounded into her.  She was chanting "Yeah ..  yeah
.. yeah ...  OH YEAH!"

   Well, it obviously wasn't rape.

   Then Jake started making noises too!  He said "You're snapping your
pussy Sandy, I'm gonna cum Sandy ...  here it comes, baby ...  OH YEAH!" He
stuck his peter in her all the way one last time and Beth Ann saw his ass
cheeks clench.  He pulled his prick out a little and slammed it back in,
grunting.  But while it was out, Beth Ann saw that his dick was coated with
streaks of white and she knew it was his sperm.

   He was shooting his sperm into Sandra O'Conner!  She might even get
PREGNANT!

   Beth Ann climbed back down the ladder and went to the counter.  Her
pussy was hot and itchy.  There was an ache in her stomach, not like she
was sick, but like she was hungry or something.  But she wasn't hungry. 
Between her legs felt ...  wet.  That had never happened before.  She
didn't know what to do about it.  She felt nervous and jumpy too.

   About then she heard noises of feet coming down the stairs.  She made
herself busy so she wouldn't have to look Sandra in the eye.  When Sandra
and Jake came back into the room he said something lame about how since
they hadn't found what she needed that they'd have to order it in.  She
giggled and said to give her a call when it got here and she'd run right
over to get it.

   She'd confronted her brother after Sandra had left the store.  A
shouting match had ensued but Beth Ann ended it by saying that if he ever
did anything like that again in the store she'd tell their Aunt.  Jake had
clamped his mouth shut, but later he whined and moaned that he'd get the
blue balls if he couldn't do something to get some relief.  In the end he'd
gotten her to agree that he could go in the back room to jerk off when he
needed to, as long as he didn't take too long.

   Beth Ann had thought that he'd be too inhibited to do it very often. 
She was wrong.  Jake could whack off six or seven times a day if he wanted
to.  And since it was his sister who'd stopped him from having REAL fun he
didn't care if his sister saw him or not while he was spanking his monkey.
As time went on he even quit trying to be private about it, standing in
plain sight as he jerked on his hot meat until it spat streams of semen up
into the air.  When Beth Ann complained that he was making messes on the
floor, he started shooting into a tissue again.  As time went on, Jake not
only didn't mind if his sister saw him, it made him even more horny to know
a female was looking at his dick.  So he ended up standing right inside the
saloon doors so that if Beth Ann went in there she couldn't help but see
him.

   He thought it was funny.  She was even more disgusted.

   Things went along that way until Beth Ann refined her interest in boys.
When Roger Dalton asked her to a school dance, and pushed her into a corner
where he commenced to kiss her until she pushed him away, she found herself
feeling exactly the same way she had felt when she saw Jake and Sandra
fucking.  Was that what Roger wanted to do with her?  She let him kiss her
some more, but when his hand cupped her breast she pushed him away again
and went back out in the light, where people could see her.  But every time
she danced close to him after that, her stomach did flip flops.

   The next day was Saturday, and Beth Ann slept late.  She wouldn't have
to take over the store until four that afternoon, so she could do whatever
she wanted until then.  She thought back to the dance, and the feel of
Roger's lips on hers, and his hand on her breast.  She knew Jake had
experience with these things.  She bounded up out of bed, still dressed in
only her T shirt and panties that she slept in each night.  She went to his
room and, without knocking, turned the knob and walked in.

   Jake was on his bed, naked, with a magazine open, showing pictures of
naked women.  He was beating off.

   "O my gosh!" exclaimed Beth Ann.  "Don't you ever do anything else
except that?"

   He'd paused at first, but then he spied her hard little nipples under
her T shirt.  The shirt didn't come down as far as it had when she'd first
worn it and he could also see her camel toe, though she didn't know she
even had one.  He started beating off even faster, fantasizing about what
was under those panties.  "No" he grunted.  "Not since you laid down the
law about doing it with girls around here." He jacked harder, staring at
his sister's breasts.  "What do you want?" he gasped.  He was going to
shoot.

   "Well ..." she started.  "Do ALL boys do that?"

   "Ohhh yeah" panted Jake, but he wasn't answering her question, he felt
the spunk rising in his balls.  Beth Ann came closer to him.  He looked so
strange, so tense, so red in the face.  He was gasping for air.  "Are you
OK?" she said, coming right to the edge of the bed.

   "Ohhhhh Yeeeaaaaahhhh!!!" he groaned and his penis spat a foot long
stream of his teenage sperm.  It was followed by six or seven others, just
as thick and just as solid.  And at least two of those splatted right on
the front of his sister's panties.  Her mouth flew open and her hand
automatically went to the spot, where her fingers slid through his spend.
She thought she'd be horrified by the feel, but it was hot, and creamy, and
slippery and ...  well ...  interesting!

   "I can't believe you did that!" she gasped.

   "Sorry" he didn't sound sorry.  He was staring at her panties.  "It's
just that I was close and you turned me on even more."

   "I did?" she was puzzled.  "Why?"

   Jake decided to tell her the truth.  It might result in her changing her
dressing habits, but who knew?  "I could see your nipples through your
shirt, and I could see your pussy." It looks like it's pretty under your
panties." He could still see them, and his cock had only gone down about
half way.  Jake was just chock full of testosterone and could often beat
off two or even three times in a row if he was motivated.  "If I could see
them better I'd beat off again." Jake was going for broke.

   Beth Ann felt her face flush.  Her brother wanted to see her naked! 
Roger had wanted to see her naked too.  And if she could watch Jake beat
off from up close, she might be able to learn how to do that to Roger and
make him happy.  On impulse she lifted her shirt, exposing her breasts and
then took it off.

   She watched Jake and his eyes got big.  His cock started getting big
too. Feeling a perverse thrill that she could affect him so, she bent over
and slipped her panties off.  When she stood back up she wanted to cover
her mons, but she disciplined herself not to.  Jake was stroking his
growing hardon now.

   "What's it feel like when you do that?" she asked.

   "Well, it's probably a lot like when you rub yourself." he said.  She
looked puzzled and he added "You know, between your legs."

   "I don't rub myself" she said, "except when I'm in the bathtub."

   Jake was surprised.  He said "Come over here.  I want to show you
something."

   Beth Ann was wary, but she figured she could trust her own brother.  She
went to the bed and he moved over to let her lie beside him.  He had
stopped stroking his cock and it just lay there, pointing at her.

   He put his hand out.  "I'm going to touch you.  It won't hurt, but if
you want me to stop, just say so.  I think it will help you understand why
I do what I do." He then moved his index finger to the tip of his cock,
which had a big dollop of milky looking stuff on it and coated his finger
tip with the stuff.  He told her to bend the knee of her top leg and she
did.  That opened up her crotch to him and he slid his slippery finger
between her pussy lips.  He wanted to stick it inside her, but instead he
brought it up to find the bump that every girl had and which made every
girl go crazy.  He found it and began circling it with his sperm-covered
fingertip.

   Beth Ann's response was gratifying.  She sucked in a big breath of air
and sighed "Ohhhhhhh that feels wonderful." He kept rubbing the diddling
her clitty until he felt the warm wetness of her own lubrication.  "You can
do this too" he said, and he slid his longest finger inside her pussy.

   Beth Ann sighed again "Ohhh my" and rolled backward to lie splayed on
the bed.  Now Jake went to town, masturbating her vigorously.  He leaned
toward her.  "And, if you let a boy play with your titties, I'm told it
feels even better." She didn't stop him, so he leaned over and sucked one
of her nipples into his mouth.

   Beth Ann didn't know it, but her nipples were tied directly to her
orgasm box, and when Jake sucked on that nipple, it jerked the string and a
whole pile of orgasms fell out.  Beth Ann was almost paralyzed by the
intensity of her first one, which was a complete surprise.  She felt the
pleasure in her nipple, in her belly, in her pussy, around her clitty,
almost everywhere, and it felt like she was going to fly apart into little
pieces.  Jake, knowing what was happening to her diddled and sucked even
more wildly, hoping that if she had a really good time, she might be
willing to do it again.

   She was.

   In fact Beth Ann became almost instantly addicted to masturbation.  Now,
when Jake went in the back and jerked off, she got hot, thinking about it.
Luckily, she could stroke herself while she stood behind the counter, but
it never felt as good as it did when Jake did it.

   So she asked him to do it again.

   He was more than happy to do so, and one day he progressed by suggesting
that it felt really good if a boy licked a girl's pussy.  She thought that
sounded pretty nasty, but changed her mind as soon as his sucking lips
fastened onto her teen clitty and blasted her into an orgasm almost
immediately.

   The strange thing was that she was getting enough satisfaction at home
that she didn't feel the urge to let Roger or any other male touch her.  It
got so that, if she was horny, all she had to do was slip into her
brother's room after their aunt went to bed and he'd lick and finger her to
all the orgasms she wanted.

   Jake, for his part, was pretty happy with things.  It got even better
when he talked his sister into tasting his cock.  She took to it like a
duck to water and soon was sucking down mouthfuls of his hot cum as often
as he asked her to.  Now, when she snuck into his room at night, they
sixty-nined happily, sometimes for hours.  In the store Beth Ann even
relented a time or two and gave her brother a blow job while they were
standing just inside the back room.  Jake could look out the door and see
if a customer came in while Beth Ann sucked happily on his cock until it
fed her what she was rapidly becoming addicted to.

   It was inevitable.  Though he was getting his rocks off regularly, Jake
missed the feeling of hot wet pussy wrapped around his cock as it shot goo
all over the place.  And so, one night, when he was about to shoot, he
jerked his cock out of his sister's mouth and said "I want to show you
something."

   Beth Ann, used to her brother showing her some new way to get a thrill,
laid there expectantly.  It hadn't occurred to her that he'd mount her and
fill her pussy with hard dick.

   But that's what he did.

   By the time she realized what he was doing, her pussy was stretched and
packed with a stiff penis.  When she drew her breath in, she intended to
demand that he stop immediately, but what came out was "Ohhhhhhhh Jake."

   Hearing what he interpreted as agreement, Jake lustily began fucking his
sister, and inside two minutes they were both knee deep in teenage orgasms.
Jake happily spurted her chock full of hot heavy sperm, and Beth Ann
happily let her spasming pussy milk it all out of him.  Suddenly she
understood the dreamy look she had seen on Sandra's face after she caught
Jake fucking her in the attic.

   As she had with everything else Jake had taught her, Beth Ann became
addicted to fucking.  First she snuck into his room at night and climbed in
bed with him.  He was always there, waiting for her, his dick hard and full
of cream.  And he was always ready to pump that cream into his sister's
willing pussy.  Quite often she stayed there in bed with him, his prick
still plugging her channel, keeping all his potent sperm in her until they
woke up later and she spread her legs for him again.

   Then, one Saturday, while their aunt was gone to visit a sick friend,
and business was slow, Beth Ann got so horny that she let Jake slip it in
her standing up in the back room.  He pinned her to the wall and jabbed his
cock up into her tender pussy until he flooded her with his baby batter.

   By the time three months had passed, Jake and Beth Ann were rutting away
at each other every chance they got, and they started making chances.  Now
it was unusual if Jake didn't slide his cock in her at least three times a
day.  They were getting to be experts at cumming within two minutes, and
they knew each other's bodies so well that they routinely reached the
pinnacle of pleasure at the same time.  But they tried not to do it quickly
unless it was just flat an emergency.  Beth Ann would rather be horny all
afternoon, if it got her two hours of dedicated fucking later that night.

   They both knew he'd knock her up.  Neither cared.  They decided they'd
raise their baby, and the eight or nine that came after it, right there in
the boonies and pass the store on to them some day.
