   While spying on her younger sister and brother, 16 year old Patty
Gilbert decides to teach the illicit lovers a lesson in responsibility. 
Her plan is very simple.  She'll attempt to bodily prevent 13 year old Anna
from hopping off 10 year old Billy's grown-up size cock in time to keep him
from ejaculating in her young fertile womb.  Things get totally out of
control when the big sister becomes ensnared in the chaos caused by her own
secret hobby!

   Patty's Hobby

   By Honey Moon





   Sixteen year-old Patty Gilbert watched with wide eyes as the action
unfolded on the small LCD screen of the very special receiver she had
bought, and almost dropped the hot glue gun in her lap.  The receiver,
along with the 2.4GHZ alarm clock spy camera kit with audio and hidden
camera, model number XH-023, had sure been worth every penny she had paid
online for it!  Her thirteen year old sister Anna collected clocks with
cartoon characters on them, and didn't suspect a thing when Patty had given
her the Winnie the Pooh alarm clock on her birthday last week.  Anna had
put it in a place of honor, right in the center of the shelf built into her
headboard.  The view was exquisite!



   Putting down her work, she turned up the sound a little higher and
adjusted her headphones to better hear what was being said.  "It's not that
I don't trust you, Billy." Anna explained to their ten year old brother as
she sat on his legs.  "I just have to be on top today."



   She could pretty much only see the top of Billy's head as it lay on the
pillow.  Well, both heads.  His erect cock was pointing right up at the
ceiling.  "Please?" he begged.  "You know I like being on top better!"



   Anna shook her head, and then pulled off her tee-shirt.  "No Billy!  You
started being able to squirt three months ago!  Why the hell did you think
I started making you use condoms?  I'm just glad that the first nut you
popped was in my mouth and not in my belly!  If I read the calendar right,
and I know I did, I'll be in GIGANTIC trouble if you even got one tiny drop
of cum in me today!  Gigantic, as in the big round baby belly I wouldn't be
able to hide very long from mom!  I'm fertile and all out of condoms!  Just
be glad I'm so damn horny today or I'd tell you to pound sand!  Take it or
leave it.  I'm going on top, and that's final!  If not, you can just go
spank your monkey and squirt the slime down the toilet!"



   Patty nodded knowingly.  She and her little sister's cycles were totally
in sync.  That's why she had stayed home to work on her ongoing project,
and to watch this unfolding family drama!  Alan, her current steady, kept
on trying to talk her into going bareback.  So far she had held him off and
she never took the risk of bareback sex.  On days she was ovulating, she
was just too horny to think straight.  It was so damn hard to keep her
willpower up and make him use a rubber.  Thank goodness her goals were so
firmly etched in her mind!  A baby in her belly would spell disaster for
her plans of entering the Air Force Academy.  Her dreams of becoming an
astronaut would end if she was saddled with a baby before graduating high
school!  Alan was a bit pissed, but these last few months Patty refused to
even see him on her fertile days!



   "Okay already!" Billy said in a huff, not wanting to masturbate if he
could be with his pretty sister instead.  "I never said I wouldn't do it
your way!  See, I'm already on my back!"



   Still a tomboy at heart, Anna raised a fist.  "That's good, but if you
don't tell me when you're about ready to pop your nut so I can jump off in
time, I'll beat the snot out of you, and you know I can do it!" she
softened her words with a smile.  "It's dumb of you to worry, though. 
Don't I always get my mouth on your cock in plenty of time to suck you
through your orgasm?" She gave her fist a little shake.  "But this time
when I stick my pussy in your face for a sixty-nine, you better lick it! 
Remember, no licky-licky from you, means no swallowing from me." Her eyes
closed to slits.  "Or do you want me to spit all that jizz in your face
again?"



   "No, that was disgusting!" he protested loudly, perhaps a little too
loudly.  "You know I like licking your pussy!  You just sat on me too hard
last time!  I almost suffocated when you were bouncing on my face!  Then I
almost died when you spit all that cum in my mouth while I was tryin' to
catch my breath!" He gave a shudder.  "I think I got sperm in my lungs
thanks to you!"



   "You swallowed every drop, didn't you?" she said sweetly.



   "Anna, that's only because you clamped a hand over my mouth, and held my
nose until I did!  I didn't wanna swallow it!" he went on in a grumpy
voice. "Everyone knows only girls are supposed to suck down a guy's load!"



   His sister laughed.  "What a stupid double standard.  Blowjobs are cool!
Why should only girls have all the fun?" she paused to slip out of her
pretty pink bra.  "Now tell the truth, Billy boy.  Have you tasted it since
then?"



   "Just once." He answered in a small voice.  "I was jerking off in my
room yesterday, um, and forgot to bring some tissues.  I caught my gunk in
my hand, right when mom was coming upstairs with the laundry!" he sighed.
"I only did it to hide the evidence!  I licked off my hand and pulled up my
pants in one split second, right before she opened the door!" blushing, he
continued in a softer voice.  "It kinda tastes good, just like you always
say it does."



   "Then how about I kiss you after you squirt all that nasty cum in my
mouth?  That way you can take only what you want."



   He thought it over for a moment.  "Well, okay.  Just don't ever tell
anyone I like the taste, okay?"



   "Oh, holy fuckin' shit!" Patty muttered.  "Who would have thought the
little runt is into incest!  She even has Billy Snowballin' his own semen!
That's just so disgusting!" She said the words with great conviction, even
as she slipped a hand down the front of her jeans to touch her moist
warmth.



   Anna actually wasn't such a runt any more.  Not since starting puberty
and developing a few tasty curves that her bi-curious sister really
appreciated!  "The tomboy sure looks good though." She sighed, staring at
her sister's lovely pert breasts, and the gentle spread of her hips. 
Nobody would think Anna was a boy from the back view, ever again!  Her eyes
were drawn to Billy's penis.  "What the hell is a ten year old doing with a
cock that big, anyway?" she asked in awe.  What is he, eight inches?  His
dork's bigger then some of the high school losers I've dated!"



   "Okay then, Billy boy!" Anna grinned wickedly.  "If you don't warn me in
plenty of time to get off of your dangerous weapon before it shoots me
down, I'll email everyone at school about how you like slurping up your own
goo!"



   Billy gasped in her headphones.  "I swear I'll tell you sis, honest! 
I'm not stupid.  I don't want to accidentally put a baby in your belly. 
Mom would kill me dead if I got you pregnant, and then send me to one of
those troubled kid boot camps!"



   Patty whimpered hearing that.  Nobody knew about her deep dark little
secret, not even her best friend Linda.  Patty had a rather strong
pregnancy fetish.  When Linda had called crying about how a condom had
somehow sprung a leak and she missed her period two weeks later, Patty had
started to masturbate even before her weeping friend had hung up the phone!
While not being weak willed or stupid enough to ruin her own meticulously
mapped out life with a baby, she seriously got off on seeing other girls at
her school sporting big round bellies.  If Linda ever found out that Patty
was the one who went into her purse, and stabbed a sewing needle through
all her condoms, her eight month pregnant BFF would never speak to her
again!



   That's how the sixteen year old had embarked on her current hobby.  She
coyly thought of it as reverse shoplifting.  After some serious online
research on just what weakens latex, Patty began spending quite a lot of
her allowance buying condoms.  She had a technique all worked out.  Using a
razor blade, she carefully opened the box.  Next, she'd take the strip of
three wrapped condoms and microwave them for one minute.  After that, they
spent a solid week buried under the stockpile of frozen foods in the big
old deep freeze out in the garage.



   The final three steps she was working on now, as she monitored the
delightful recording she was making with her hidden camera and brand new
DVR.  Her friend Greta was diabetic.  Patty had managed to steal a few
unused insulin syringes from her.  She didn't do anything as crude as her
first attempt with Linda's pin holes.  Her technique was far more subtle
now.  Using the very fine point of the syringe, she'd carefully pierce the
condom wrapper, and inject a droplet of baby oil directly against the
latex. Using superglue, she then sealed the hole in a manner that was very
close to invisible.  Last but not least, she used a hot glue gun to reseal
the boxes.



   Over the last seven months or so, she had snuck nearly a hundred altered
condom boxes into every store within walking distance of her high school!
Since excessive heat, excessive cold, and contact with petroleum products
each on their own cause the breakdown of latex and ultimately condom
failure, Patty was confidant in her triple whammy!  She was certain that
quite a few baby bumps around school were her handiwork!  Every time she
heard the whispers about so-and-so really did use a condom, but it broke,
she could hardly wait to get home and masturbate after hearing about
another girl's delightful tale of tearful woe and morning sickness!



   A movement on the screen shook Patty out of her reverie to concentrate
on the here and now.  Topless, Anna had climbed to her feet to stand over
Billy.  Patty had a simply delicious view as her sister slipped down her
shorts, and then stepped out of her panties.  He mouth watered at the sight
of her thirteen year old little sister's neatly invisible wispy blonde
bush. Patty couldn't help a little satisfied grin.  She thought it was
simply adorable that Anna had left on her little lace trimmed ankle socks!
"Remember Billy." She whispered as she settled back over him.  "No funny
tricks or everyone at school will be calling you cum junky!"



   Billy actually saluted.  "On my honor as a Boy Scout, I swear I'll tell
you when I feel the very first hint that I'm gonna squirt soon!"



   This was too much!  Unplugging the glue gun, Patty began struggling out
of her own clothes, getting all tangled up in the cord when she forgot to
take off the headphones.  She'd seal up this batch and stash it in her
backpack later!  Patty spread her legs wide and began to touch herself, as
Anna grasped Billy's cock and rubbed the head over the pouty lips of her
pretty pussy.



   "I'll trust you." the lovely girl whispered as she began to slowly
settle onto his erection.  Her sigh was one of heavenly bliss as Billy's
penis pushed ever deeper into her body.



   "Anna, it feels so much better without a condom!  You're so warm and wet
inside!" Billy moaned as his sister began to slowly move.



   "You better remember your promise!" she hissed, as she leaned forward
and planted her hands on his chest.  "Warn me in time, or else!"



   Patty watched as her sister sensually rolled her hips on top of their
little brother.  "Damn, I need a fuck." She whimpered as her fingers
strummed over her soaked labia.  Anna began to hump Billy, fucking his man
sized cock in and out of her tight body.



   "She's risking so much!" the older girl whimpered, while slipping a
finger inside.  "Oh God, if he loses it and cums, Anna will get knocked up
for sure!" she whimpered "His pre-cum might even be doing the job and
getting sperm in her right now!"



   Patty was on her feet with no conscience though.  "Mom won't be home for
hours!" she muttered while licking off her slick wet fingers.  She switched
off the receiver's built in screen.  Coiling the cable neatly, she placed
the small unit carefully next to the still recording DVR.  "Now I gotta
teach Anna a lesson!"



   She pulled open a dresser drawer, and grabbed three silk scarves.  "Oh
God, I gotta hurry before it's too late!"



   Running naked down the hall, Patty stopped and ran her fingertips along
the top of the bathroom doorjamb.  It was still there!  The little odd
shaped safety key glittered in the palm of her hand.  When he was only
seven, Billy had gone through a phase where he would lock himself in the
bathroom, and play boats in the sink until he flooded the room, and water
would drip down into the dining room.  Anyone nearby was charged with
unlocking the door and dragging him out before the ceiling collapsed!  The
wonderful little key would unlock Anna's door, just as easily!



   Quietly as she could, the sixteen year old slipped the key into the
little hole in the doorknob, and slowly twisted it.  The click was so soft,
she felt, rather then heard it.  Holding her breath, Patty crept into the
room.



   Anna was really riding Billy now, her lovely blonde hair whipping around
her face as she rode her brother like a champion cowgirl!  "Anna, I, I
think it's soon!" he gasped.  "Get ready!  I, I'm about to cum!  Y-You
promised to suck it out of me!"



   Patty's heart raced.  She was just in time!  Throwing caution to the
wind, the big sister charged into the room and grabbed Anna just as the
younger girl was trying to dismount their brother!



   "Good boy!" the thirteen year old panted.  "I'll suck you so hard
you'll' She never finished her promise.  With no warning, she was shoved
down completely prone onto her brother's trembling body.  "What?  Get off!"
she suddenly cried, "Patty, what the hell are you doing?"



   Patty climbed onto her siblings, and wrestled with Anna's flailing arms.
"Bad little girl!" she scolded, as she wrapped a scarf around her
struggling sister's wrists and bound them firmly together.  "Look at you
riding bareback on our little brother!  I'm going to teach you to take
responsibility for your actions, baby sister!  If you want to take a ride
on the baloney pony, you have to pay the price of the ticket!"



   Billy wasn't stupid.  He knew exactly the price that would be paid if he
even let out even one tiny little squirt!  A drop no bigger then the period
at the end of a sentence would have way more then enough sperm to give his
sister a big belly!  "Anna, don't move!  I, I'll cum if you move too much!"



   "Patty, get off of me!" the chronological and now literal middle sibling
cried, holding as still as she could.  "I'm not fooling!"



   The older girl lay completely over her sister, and began to slowly rub
her breasts against Anna's back.  "I won't get off, but I bet Billy will!"



   Anna felt her sister straddle her right leg with both of hers.  She felt
moist silky warmth press against the back of her thigh.  "Stop it!" she
begged, as the bigger girl began to hump her leg.  "You, you're making me
fuck him!  Stop it!"



   "Poor little girl, experimenting with unprotected sex." Patty whispered
throatily as she tribbed against Anna's lovely leg.  "In nine short months
you're gonna pay such a huge price for being horny enough to risk riding
bareback!"



   Billy's eyes were open wide in near panic.  "Don't move!  Anna, don't
move!" he begged, trying his hardest to ignore how wonderful he felt under
both of his sexy sisters.  "Patty, stop making her move!"



   "Little brother, you're now a man!" Patty moaned "Cum in your woman! 
Put a baby in her belly!"



   Anna was whimpering.  She had been so close to climax when Patty
attacked, and was now in serious danger of being pushed over the edge while
trapped between her brother and sister!  "Billy, please, please don't cum!"
she begged.  "Not inside me!  Not now!  Please Billy, hold it in!"



   "I'm trying!" he cried, grabbing the sheets tight in his fists, and
digging his toes hard into the mattress.  "I, I'm really trying to hold it
in!"



   "Let it go!" Patty whispered dreamily.  "It's okay Billy.  This is all
Anna's fault!  Just squirt in her pretty belly, and we can watch it get all
big and round as your baby grows inside of her!"



   "No!" Anna screamed, trying to fight her approaching orgasm.  "Billy,
Billy please!  Don't cum!  I, I'll give you my iPad if you don't cum!" she
recognized the look in his eyes, and wailed.  Billy was just a few
heartbeats from exploding!  "No!  I'll give you my allowance for a year! 
Just please Billy, try and get your cock out of me before it's too late!"



   He tried, but that was about the worst thing he could possibly do in his
over excited condition.  His wild attempt to buck both sisters off of his
body only drove his cock even farther into his sister!  He felt himself
touch deep inside of her!  "Oh Anna!" he cried, as his cock began to throb.



   "Oh no, oh please Billy, don't do it!" Anna begged fearfully as she felt
Billy's cock move within her.  "Hold it in!  You can't cum inside me today!
I really mean it!  It's way too dangerous!  I could get pregnant!  Please
don't squirt sperm in me!" she managed to scream as her body was overcome.



   "I can't stop it!" Billy wailed as he felt Anna's insides ripple and
caress him.  There was no way a horny young man could possibly have the
willpower to stand firm against that!  He let out a groan.  Deep inside
him, muscles contracted.  He thrust up again against the weight of both
girls, and his cock gave a jerk.  Thick hot fluid raced from deep within,
surging and pulsing up his proud stiff manhood, to ejaculate right against
Anna's cervix!  Again and again, thick slimy cords of semen spurted deep
into his sister's writhing body!



   Patty let out a cry!  Her brother and sister were both cumming!  She
ground herself against Anna's leg, and she was off too!  Her mind's eye saw
every jet of milky pearly goodness blasting deep into Anna, and the power
of her release was almost frightening in its intensity!



   She couldn't give herself the luxury of relaxation though!  "Out of the
way!" she gasped when Billy finally stopped moaning and rutting up at his
sisters.  Patty dragged the almost insensible Anna off of him, and flipped
her over onto her back.  Working quick as she could, she tied both of her
sister's ankles to the headboard of the bed.  Legs spread wide; Anna's butt
was raised high enough so that she didn't waste a precious drop of her
brother's cum in something as showy as a creamy-pie!  Patty grabbed her
sister's pillows though, and stuffed them under the panting girl's rear
end. She didn't want her to be uncomfortable, after all.



   "Oh God, let me go!" The bound girl whimpered when she finally felt she
could talk again.  "Patty, it may not be too late!  Let me go try and drain
it out of me!"



   Patty sighed happily.  "I'll untie you in an hour, kiddo.  "I just want
to give Billy's sperm a good running start.  Or should I say swimming?" she
giggled.  "Thanks guys, that was so exciting!"



   Billy crawled over the bed to try and untie his sister.  "Let her go!"
he cried, when Patty pushed him away.  "I, I'll call the cops if you don't
untie her!"



   "That would be dumb, William." She eyed her brother's still hard cock.
"I'll tell you what.  If you leave Anna just the way she is until I say you
can untie her legs, I'll let you fuck me.  How's that sound?"



   "Billy no!" Anna cried, struggling to get at least one leg free.  "She's
bribing you!  This is so wrong!  What, what if you got me" he voice dropped
to a frightened whisper "Pregnant?  I have to at least try and let some of
the semen drain out!  It's my only chance!"



   "She'll look so cute with a big belly." Patty sighed happily.  "Billy, I
remember how much you liked drinking from mom's breasts.  How would you
like to taste Anna's milk?"



   Billy's mouth dropped open.  Anna's breasts would get bigger if they
filled up with milk!  His mouth actually watered at the thought of drinking
warm milk from them!  That wasn't the deciding factor, though.  Anna sure
was sexy and hot, but Patty, Patty was, Patty was a CHEERLEADER!  He lost
track of how many times he had jerked off, pretending his red headed big
sister was Kim Possible, but with bigger tits!  His cock gave a happy jerk.
"Um, okay!" He moved towards his older sister.  "I'll do what you say if I
get to fuck you!"



   Patty pushed him away again.  "Not without a condom, buster!  Get a
washcloth and clean all the cum off your dick, too.  I'm not stupid enough
to take any chances!"



   Anna whimpered.  "I'm not stupid!  I, I had plenty of time to get off
and switch to doing a sixty-nine!  "I'm telling mom!"



   "Tell her what, that you and Billy were doing the horizontal bop?  You
got carried away while doing the Mattress Mambo?" Patty giggled.  "Mom
would throw a fit if she even suspected anything as weird as incest!  Do
you want to end up on Dr.  Phil, or something?"



   Billy had more practical matters in mind.  "Patty, we don't have any
condoms."



   Anna struggled harder, and came very close to freeing her left leg. 
Patty jumped to grab her.  "I have some.  Go clean your dick, and then
check the top drawer of my dresser.  I keep them under my panties."



   "I'll find them!" he called happily, as he ran from the room.



   "Patty, let me go!" Anna said softly, tears in her eyes.  "I really
could be pregnant!  I just have to try and wash Billy's sperm out of me!"



   "I know, sweetie." Patty boldly leaned down, and gave Anna a very
un-sisterly kiss.  "We're in sync.  I know for a fact I'm ovulating today,
so that means you are too." She slipped a finger playfully into Anna's
warmth, and gave it a friendly little wiggle.  She pulled the digit back
out, and very carefully licked and sucked it clean.  She didn't dare risk
touching herself with sperm on her finger!  "Wow, Billy made you all soupy
inside!  Just think!  Millions of wiggly swimmers are right now trying to
find your egg!  Isn't that the hottest thing you ever heard of?"



   "No it isn't!" Anna gathered herself together and stopped crying.  "I'll
get even, big sister!  You're right, I can't tell mom, but remember this!
Like the saying goes.  Karma is a bitch!"



   Billy came back to the room at that moment.  "Patty, I'm all ready!" he
announced.  "I washed my penis like you said, and even peed so all the
stuff would get rinsed out." He triumphantly waived a strip of condoms.  "I
got the rubbers too!  Can we really fuck now?"



   Patty smiled.  She was just as eager as her little brother.  "We sure
can!  You have to make a pact with me though." She nudged her prone sister.
"You too, mommy!" Patty solemnly raised her right hand.  "I swear by all I
hold sacred, that I'll never tell a living soul that I had sex with members
of my own family!"



   Billy eagerly complied.  Anna did so a bit more reluctantly, but knew
that her brother and sister would never break an oath shared this way
between them.  "I'll still get even though!" she hissed, as Patty shoved
her over a little to make room for her and Billy on the bed.



   "Now can we fuck?" Billy asked anxiously as he climbed into bed with his
sisters.  "I'll put on a condom!"



   Patty snatched them from his hand.  "I'll put the condom on you!  I'm
not having any mistakes!"



   "I know how to do it!" he grumbled, as his big sister tore open a
packet. "Anna always gets them from the dollar store.  She just didn't have
one today, that's all!"



   "You trust condoms from the dollar store?" Patty hadn't bothered
slipping any of her altered beauties into their local dollar store's stock.
They would have stood out, name brands among the off-name junk.  Besides,
she always thought any girl dumb enough to trust dollar store condoms,
would be a mommy soon enough without her help!



   "Billy, we only used them that one time and you know it!!" Anna
protested.  She continued sheepishly.  "I was really horny, and I was
pretty sure I was safe that day anyway!"



   Giving Billy's cock a sweet little kiss, Patty then expertly placed the
prophylactic on its lovely swollen head and pinched the air carefully out
of the reservoir tip.  Caressing him lovingly, she rolled the condom down
his rigidly engorged shaft.  "It's a wonder you guys haven't made a baby
together before today!  There's no way I'd ever be stupid enough to let a
guy slip his naked cock up in me, I don't care what part of my cycle I'm
on!" They didn't have to know about her recent crisis of willpower over it.
"I'm always careful.  I've never taken a load in my belly yet.  The risk is
too great!"



   "Stop talking about babies and guy's loads!" Anna cried.  "Billy, you
said you like the taste!  Please, I'll still let you have my iPad, if you
try and suck it all out of me!"



   "Anna, shut up!" he yelled, blushing nearly as red as the hair color he
shared with his older sister.  "You said you wouldn't tell anyone!"



   Patty pulled her brother to her and gave him a kiss.  It pleased her
greatly when he parted his lips and let her tongue into his mouth.  She
sighed when they parted.  "Billy, I had no idea how much of a man you
really are.  Only a true man is so confidant in himself, that he'd be open
to a little sexual experimentation."



   He sat up taller on the bed.  "That's right!  I was curious, and, um,
thought that if I was making a girl eat my gunk, then I should maybe taste
it myself!"



   "You big fat liar!" Anna called while struggling once again to get free.
"I had to make you do it!"



   "I am not a liar!" he yelled.



   "Just ignore the little unwed mother." Patty laughed.  "It's not her
fault she's so cranky.  It may be early, but I'm betting it's just her
surging hormones talking.  When we're done, we can give her a nice bowl of
pickles and ice cream to calm her down!"



   "I'm sorry!  I know you're not a liar!" Anna shouted as Patty lay down
along side of her.  "Billy please, you have to think about this!"



   That was the trouble.  Billy was a kind hearted well behaved little
brother, but he was thinking about this!  All his wildest wet dreams were
coming true!  "Anna, when you start making milk, you gotta let me suck your
tits!" he announced while climbing over a giggling patty.  "It's only fair
if I was the one who put a baby in you!"



   Patty spread her legs wide, lifting her knees so her right leg wouldn't
smother her bound sister's face.  "Oh Anna, I can't wait either!" she
giggled almost manically.  Having a pregnant girl in the house was going to
be wonderful!  "You take after mom so much, I bet you'll have the same
problem she had while having us!  Ask her.  Mom always says that the only
part of having children she didn't like, was how she always over lactated!
I was only six, but I can still remember all the bottles mom had in the
refrigerator, and how she told me they liked it at the hospital to help
with all the pretty new babies."



   Patty very nearly climaxed just thinking about it!  "Oh Anna, I'm gonna
buy you a breast pump!  I'm gonna start milking you every morning!" She
reached for her brother's latex encased cock, and helped guide him into
her. "I'll even sneak your milk into mom's morning coffee!  When her
boyfriend comes over, I'll give him some too!"



   Billy couldn't help giggling.  "Patty, do you think we could, um, try
making ice-cream?  Milk is milk, right?  We haven't had home made ice-cream
in ages!"



   "That's a great idea!  We'll find out, kiddo!" She placed the head of
his cock against her opening.  "Anna, I won't let you dry up!  Mom was
still making milk nearly a year after Billy was on solid food!  I bet I can
keep your dairy producing until you graduate high school!"



   "Shut up, you, incestuous perverts!" Blushing, Anna tried to look away,
but she couldn't help watching as Billy entered their big sister.  "You
wait and see!  I'll luck out, and won't get pregnant!" She glared at her
brother's cock.  "Billy, don't ever expect anything from me again!  I'm
cutting you off from now on!" She hated herself, knowing this was probably
a lie.  Why should she date the assholes in her class, if she had Billy to
tend to her needs?  "If, if I'm pregnant, you'll never get more then a
blowjob out of me, understand?"



   "I'll take care of you, Billy!" Patty laughed.  She settled back as
Billy slowly eased into her.  "Now do your thing, stud!" She put her hands
on his tight little rump, and urged him to begin thrusting.  "Remember
though, as soon as you cum, grab the base of the condom and SLOWLY pull out
of me.  I don't want one drop spilled!" she would secure the filled latex
balloon, and run downstairs to the kitchen.  If she stuck a funnel in
Anna's pussy, she could dump Billy's second load into her to help insure
conception!



   Billy thought he was just about the luckiest guy in the whole world! 
Sure they were his sisters, but they were also the two prettiest girls he
knew!  One of them might be having a baby because of him, but his ten year
old libido was going crazy at the thought.  He somehow guessed what his
sister had planned for the condom.  "Patty, ask Anna, I can go four or five
times!" he stared at the younger girl's prone and defenseless body.  "I bet
I could climb on top and do her like that!"



   "No, no you won't!" Anna yelled, watching as his grown up cock moved
with powerful long strokes in and out of his current lover.  "I don't want
any more cum in me!"



   Patty patted her sister's tummy.  "A little more certainly wouldn't make
things worse!" she sighed happily as their brother moved his hips with just
the right motion.  She began kneading and caressing her own breasts, glad
that her own 44DD bosoms wouldn't be increasing with an unwanted pregnancy!
She slowly became aware of a familiar scent.  She sniffed her fingers. 
"Baby oil?" she whispered, heart almost stopping.  "Billy, w-where did you
get the condoms?"



   Billy, hands braced on the bed, was really going crazy!  Somehow, having
Anna watch made this so much more exciting and fun!  "Don't worry, Patty!"
he panted happily "I didn't go snooping through your panty drawer.  I just
grabbed the strip that was sitting on your desk, next to the opened box and
the glue gun."



   "Oh no!" the sixteen year old moaned.  He grabbed the wrong ones!  She
was getting screwed with her specially weakened condoms!  "Billy, let's
finish you off in Anna, `kay?" she said hopefully, trying to gently but
firmly nudge him off of her before it was too late.



   Billy struggled a bit, and only thrust harder.  Suddenly, with a sort of
popping sensation, things felt so much warmer and wetter inside his sister!
It was wonderful!  "Feels too good now!" he proclaimed, as he slipped his
arms under Patty and lay fully on top of her.  "I'll do Anna again next!"



   Anna was almost hypnotized by the sight of Billy's thick organ plowing
their sister so powerfully.  It almost made her forget her own precarious
position.  It took her several of his strokes to realize just what she had
seen.  One stroke, his pretty cock was fully encased by the glistening
sheath.  The next stroke, the latex was all bunched up and baggy against
his balls, leaving his penis totally free and naked as it continued to
plunge into Patty!  "Karma!" she whimpered, wishing she had a hand free to
masturbate as she watched her sister's downfall!



   "Billy, I want you to stop now!" Patty ordered weakly, trying to gather
herself to push him off.  Part of her was screaming inside to just shove
him off, but he was holding her so tightly and she felt so weak and
powerless under him!  "That's enough!  We, we might have a problem!"



   His thrusts slowed.  "Huh?  I, I don't wanna stop!" He grumbled, feeling
his big sister's warmth enveloping his throbbing hardness.  "It feels too
good to stop!"



   She did manage to worm a hand down between them.  Her fingertips felt
baggy wet latex, and the naked hard flesh of her brother's cock sliding in
and out of her!  "You can titty fuck me!" she cried, trying not to feel the
sensual delight of a naked cock invading her fertile body.  "Then, then you
can shove it in Anna when you're about to cum!"



   "This feels too good!" he repeated "Why should I stop now?"



   "The condom broke!" she wailed.  "Pull out right now, and you can get
one from my dresser this time!  Either that, or stuff your cock into Anna!
She's already full of cum!"



   He slowed to a stop.  "Okay, uh, okay Patty.  I, I have to wait a
second, or I might squirt when I try and pull out!"



   "Hold still!" Patty cried, trying to keep her own body immobile.  "Think
about ice cubes and dogs with big teeth!"



   Billy was being responsible!  Anna thought that just wasn't fair!  She
opened her mouth to demand he really give it to Patty, but a sudden idea
came to her.  She knew her little brother's weakness!  He had confessed his
following of a certain cartoon, and just who in his every day life reminded
him of his hero!  Very softly, she began to sing.  "I'm your basic average
girl and I'm here to save the world, you can't stop me 'cause I'm Kim
Pos-i-ble."



   Billy moaned deep in his throat, and began to move his hips again. 
"Gonna knock up Kimmie-Cub!" he cried, as he resumed his powerful strokes.



   "What, Kimmie-Cub?" Patty gasped.  "No, you stopped!  You have to stay
stopped!  You can't knock me up!" she whimpered as her legs obeyed some
million year old biological need instead of common sense, and wrapped
around him.  "I, I can't get pregnant now!  I, I'd be ruined!"



   She couldn't help herself!  Patty had become a slave to her fetish! 
Over a span of nearly nine months, she had inadvertently conditioned
herself on a daily basis to become immensely aroused at the mere thought of
a condom breaking in a girl and getting her knocked up against her will. 
It was all she ever thought about while having protected safe sex, or
masturbating nightly before going to sleep.  Now that she was the victim of
her own tampering spree, it was affecting her a hundred times stronger! 
She knew with dreaded certainty she had to do something, but was completely
powerless to stop the impending gooey disaster!



   "Please?" she whimpered, unable to do anything but hold her brother
tightly while he pounded into her like a wild animal!  "I don't want to
have a baby!  Not me!  Not now!  I'm too smart for that!  Oh God, Billy,
you have to stop before it's too late!" Her intellect may not have wanted a
baby, but her fertile sixteen year old body sure did!  She was right at the
abyss, and Billy was pushing her over!  "Oh please, not now!" she wailed,
as she launched into the most powerful orgasm she had ever experienced! 
She knew the effect it would have on her brother, but she just couldn't
stop her spasming body from wildly humping up at him!



   "I'm gonna cum!" Billy announced needlessly as his body tensed up. 
Patty was wildly thrashing and writhing, almost throwing him off as she
panted and cried.  He held on tight though, and rammed in just as deep as
he could!  He practically exploded!  He grunted again and again, marking
each spasm as his warm virile semen ejaculated deep into his beautiful
sister.



   It was happening!  Part of her mind cried in fear as Patty felt her
brother's cock jerking within her.  Fear or not, knowing that live wiggling
squirming sperm was being blasted directly against her cervix as the pearly
hot semen pulsed thickly out of Billy's pee slit, caused her to cross from
one peak to another!  She cried out as she shuddered from one orgasm right
into another more powerful one!



   When it was all over, Billy grabbed the base of his cock and slowly
pulled out of his still panting sister.  "Um, I, I'm sorry Patty.  I guess
you weren't kidding.  The condom really did break!"



   Patty just laid there and sniffed back her tears.  "What have I done?"
she whimpered.  "I ruined myself!  I made my own condom break!"



   Anna sighed as Billy finally untied her ankles from the headboard.  She
sat up and rubbed her wrists when she was finally free.  "Don't be stupid,
sis.  You may have forced me to get a belly full of cum, but how on Earth
would you be able to make a condom break?"



   "Forget about that!" Patty said fearfully, suddenly wishing she had
never decided to fool with fate and mess with condoms!  "I, um, we, we have
to go to a drug store and get the morning after pill!"



   The three siblings dressed hastily and headed down stairs.  "Billy, you
stay here.  I swear we'll keep you out of this." Patty announced as she
swiped her mother's car keys from the bowl on the telephone table in the
hall.  "We'll go to the all night pharmacy, and say we overpowered at a
wild Frat Party or something!"



   Just as she reached for the door, it opened on its own.  "Kids, what are
you still doing up?" Their mother announced rather hotly as she walked into
the house.  She was followed by her boyfriend.



   "Kelly, give me a minute to call a field office." He said quietly, while
trying to act calm and casual.  "I can head things off, and hopefully
prevent a media explosion."



   Patty looked at her mother's face, and could see how angry and upset she
was.  "Mom, what happened?"



   Before her mother could answer, her boyfriend placed his call.  "This is
Agent Frank McCoy.  I have a solid lead on the product tampering case." He
paused.  "Yeah, it's like we suspected.  It was just a kid." There was
another moment of silence.  "Boss, I never asked for a favor before, but
let me play this out, okay?  Yeah, I'll give you a complete report in the
morning."



   Oh shit!  Patty couldn't help glancing downward as her angry mother sort
of fidgeted and tugged at her slacks.  Her eyes opened wide as she noticed
a distinct damp spot right at crotch level!  "Oh no!" she breathed.



   "Oh yes!" Kelly Gilbert glared at her eldest daughter.  "Billy, Anna,
get to bed!" she snapped.  "Patty and I need to have a little talk!"



   "Fuck!" Anna grabbed her brother's hand and dragged him up the stairs.
Something was going on, and it looked like the morning after pill idea was
all washed up!



   Frank gave his girlfriend a kiss.  "Sorry about tonight, honey.  I'll do
my best to minimize things down at the office.  Call me in the morning."



   In minutes, Patty was alone with her mother in the living room.  "So,
uh, how was your date?" she asked softly, trying not to stare at her
mother's growing dampness.  She'd have a matching spot herself, if she
hadn't followed Anna's lead and shoved in a tampon to hold back the flow of
Billy's surprisingly large load.



   "Patricia dear, I've known for months that you were sexually active, but
I also knew you were responsible, and was using protection.  That's why I
let you experiment with your sexuality." The older woman took a deep
breath, and ignored her blush rising on her lovely face.  "This afternoon,
I was getting ready for my date with Frank.  I went to your room to borrow
a pack of condoms from your backpack."



   "Oh fuck!" Patty gasped.  "Mom, you shouldn't have snooped through my
room and gone through my stuff!  I, I would have given you some if you just
asked!"



   "Your stuff?" Kelly glared at her daughter.  "Any stuff in this house
belongs to me!  It's my paychecks that pay for it all!  That isn't your
room upstairs, either.  It belongs to me!  I just let you sleep in it!" She
calmed herself down with an effort.  "Frank and I had a lovely dinner, and
then retired to his house to, uh, watch a movie." She pulled a condom
package from her purse and threw it in Patty's face.  "Imagine my surprise
when the condom broke.  Imagine Frank's surprise when he examined the
packaging, and noticed it was one of the tampered condoms from the case
he's working on!"



   "I, I must have b-bought a dud package!" Patty whispered fearfully.



   "Don't give me that bullshit!" Kelly shook her head.  "The FBI has a few
partial fingerprints from a couple of the tampered condom packages.  Frank
wants me to give him permission to take your fingerprints, since you aren't
in the system.  You tell me right now what they'll find if I say yes!"



   Tears filled Patty's eyes.  "I did it." She whispered.  "Mom, will, will
I have to go to jail?"



   Kelly sighed and hugged her daughter to her.  "Honey, I'm very angry
with you right now, but I made Frank promise to do everything in his power
to prevent that!"



   Patty counted herself seriously lucky over the next few weeks. 
Thirty-eight girls and women around town had been knocked up thanks to her.
The thing that had saved her was it had turned out that Miss MacAulay,
Billy's own teacher, had been knocked up by Billy's best friend Mark!  She
was arrested and charged as a pedophile.  She was never charged with it,
but due to careful wording of the official FBI report, the media ended up
speculating that she had been responsible for the condom tampering all over
town.  She, Anna and Billy had all renewed their pact never to say they had
sex together after that bit of exciting news!



   Life was far from rosy for the troubled teen though.  One morning while
she and mom were drinking orange juice, and discussing their respective
positive home pregnancy tests, Anna had charged into the kitchen smiling
from ear to ear.  "Mom, we're almost out of tampons." She stared right into
Patty's eyes, and stuck out her tongue while their mother couldn't see. 
"My period was a little late this month, but it finally started today.  I
have a few in my bag, but could you get more when you go shopping later?"



   "Don't worry about being a bit irregular, honey.  You only just started.
You'll probably end up being as regular as a clock like your sister and I,
before long." She smiled sweetly.  "Just go to the closet in my room,
honey. I have a whole box I won't need this month.  Help yourself."



   "Wow, does that mean?"



   "Frank and I are getting married, and you're going to have a little
brother or sister." She sighed knowingly.  "It seems you'll have a baby
niece or nephew, too, won't she, Patty?"



   "Yes mom." The teen answered quietly.  "I, um, I guess so."



   "That's so cool!" Anna grinned.  "I can almost count the baby sitting
money now!"



   Thirty-one year old Patty Gilbert held her gravid belly and waddled out
of the doctor's examination room.  She sighed.  "Sarah, what were you
thinking?" she asked her fifteen year old daughter.  "I told you not to
have sex until you were married!"



   The lovely redhead just shook her head.  "Mom, don't be such a
hypocrite! Look at you!  You're about ready to pop out a baby right now! 
Where's your husband?" She looked up and froze.  "Wait a minute!  It looks
like it's time!"



   Mother and daughter looked up at the wide screen monitor window covering
the entire wall of the waiting room.  "We have been told radio contact has
been reestablished with the Lander!" the announcer said excitedly.  "The
crew has drawn straws, and yes, we have word now.  Mission Specialist Anna
Gilbert will be the first to exit the vehicle!  Hold on, we are switching
to the live feed now!"



   The screen changed to show the magnificent desolation of the lunar
surface.  A bulky form in an orange pressure suit was slowly making its way
down a ladder.  It hopped down the last few feet.  "We're back!" a playful
voice announced as the suited figure took a few trial steps on the dust
covered surface.



   "Man has returned to the moon!" the announcer screamed.  "Anna Gilbert
is the first woman in history to step foot on another celestial object!"



   Sarah literally jumped for joy.  "That's my aunt!" she cried happily. 
"She's the first woman on the moon!"



   The people waiting to see the doctor all started applauding as the
pretty girl excitedly laughed and cheered at the screen.  Nobody seemed to
notice as her very pregnant mother began to cry.  "That was my dream!" she
whimpered softly.  "That was supposed to be me!  I was going to be the
astronaut!" The Air Force academy had never happened.  Patty had to get a
job right out of high school in order to help pay for all the expenses of
having a baby.  It just wasn't fair!  Mom had put Anna on the pill right
after finding out Patty was pregnant with Sarah.  The little bitch had even
kept up her torrid little affair with their brother Billy, right up to when
she left to go to college!



   She put her hand on her belly and sniffed back her tears.  Billy had
taken a little leave from the Army, and had just missed Anna who had gone
off nine months ago for serious survival training in preparation for this
mission.  Patty felt like some kind of consolation prize when he had ended
up in her bedroom late during his last night.  Somehow no hadn't meant no,
and she ended up letting her brother go bareback after he promised to pull
out in plenty of time.  Of course he didn't!



   A thought struck her, as she watched her sister gather samples of the
moon's surface.  The doctor had said Sarah was six weeks along.  Six weeks
ago Billy had spent the night while waiting for his transfer orders to come
through!  He and Sarah had acted awfully funny the next morning.  Does
history always repeat itself?  She felt sudden warmth.  "That's just
great!" she shouted at the world in general.  "Now my fuckin' water broke!"
