Knocking Up Sister's Friend
by Beating Off Bob (beatingoffbob@yahoo.com)

***

Brad can't keep his mind off Elizabeth, his sister's 
best friend and. In a fit of frustration he shows her 
just what happens when he thinks about her. That leads 
them down a path that makes her belly swell. But the 
story isn't over there. What will sister do to the man 
who ruined her friend? (MF-teens, reluc, rough, inc, 
1st, preg)

***


Brad was bummed. 

It was Saturday again. He was beginning to hate 
Saturdays. It was supposed to be a day he could have 
fun and do what he wanted, but... Elizabeth would be 
here most of the day. 

He knew she would. 

She always did. 

She also came over to see his sister Renee every day 
after school too. They were best friends. It wasn't so 
bad during the week, because he could stay in his room 
and do homework or at least pretend he was doing 
homework. Then he could MAYBE keep his mind off her.

Elizabeth and he were both ninth graders, so he had 
been plagued with her for over two years. Ever since he 
had noticed... well... HER. He'd known her forever. 
She'd gravitated to his younger sister when they'd 
moved to this one horse town and stuck like glue ever 
since. Technically they were a year apart, but in 
reality it was only three months. Elizabeth was born in 
October and Renee the following January.

He thought of her now. Her breasts. Wow, what boobs she 
had. They stuck out now so much that he almost couldn't 
look at any other parts of her. Not that those were bad 
either. She had what they call an Elfin face, with 
short straight hair down to the bottom of her jawbone. 
When she shook her head it flew in all directions and 
then just lay right back down where it belonged. Her 
eyes were dark green and she had plump... kissable 
lips. 

She wasn't skinny, but she wasn't really fat either. 
She had flesh everywhere, but it was shaped just right. 
Her hips went out from her sides somehow so that if you 
were facing her she looked like someone was blowing up 
a balloon there, under her pants, but it made her 
marvelous breasts look just right somehow. She wore 
halter tops all the time in the summer, with no bra. In 
the winter she wore these thin sweaters that curved to 
the shape of her boobs like skin. She was tall for a 
girl, probably 5' 10" and her legs were really long 
looking. She was almost as tall as he was now and he 
was afraid she was going to catch up some day.

Every time he saw her his dick got hard. Just like it 
was right now and all he was doing was thinking about 
her. It had gotten to the point that he had to jack off 
twice a day! All he had to do was imagine her naked, 
holding her arms out to him and he'd spurt three feet. 
He'd actually seen her naked - lots of times - but that 
was years ago when they skinny dipped in the creek. She 
didn't have any real breasts then, and he couldn't put 
the mountains she how had on that memory for some 
reason. It made her look like she'd fall over or 
something.

And she'd be around all day today. 

And he'd be tormented and have to find some time and 
privacy to beat off while she was there. That or walk 
around bent over all day. She didn't actually tease him 
or anything. She was actually nice to him. They were 
friends, after all, and had been for a long, long time. 
She treated him lots better than Renee did. 

He'd swear his sister hated the air he breathed. She 
was always calling him "toad face" or "shit-for-brains" 
(but only when there were no adults around for that 
one), or "Wimpy". He didn't get it. He certainly didn't 
look like a toad. He got straight 'A's in school. He 
won the swim meet nearly every year and was in fabulous 
shape. What was her deal? 

He didn't hate HER. He thought she was beautiful. Well, 
more like cute. She was blond and wore her long hair in 
a pony tail most of the time. Sometimes dog ears. Her 
boobs weren't as big as Elizabeth's. He'd seen her 
naked at one time or another all his life. She had 
interesting nipples. The areola of each breast was 
thick and puffy and stood out from the breast flesh 
like a little pillow or something. 

Then, on top of THAT was a big fat nipple. The nipple 
and areola were almost exactly the same color, and if 
you were facing her she just had large brown circles in 
the middle of her breasts. But if she stood sideways 
you could see that her nipple actually stood out half 
an inch or so. She hated her breasts because if she 
wore anything thin without a bra that whole silver 
dollar sized pillow-with-a pencil-eraser-on-it stuck 
out and made her look what she thought was deformed or 
something. 

He remembered seeing her a couple of weeks ago, coming 
out of the shower. She was naked, of course, and was 
drying her hair with a towel as she walked back to her 
room. Her arms were above her head and her breasts were 
stretched upwards a little. He was surprised to find 
himself thinking that those brown circles looked just 
the perfect size to fit in a guy's mouth. 

He was horrified to find that he had to beat off before 
he could think about anything else.

Part of the problem was that Renee had a paper route. 
She made pretty good money at it, but she had to do her 
route six days a week. She used to ride her bike and it 
only took an hour, but nowadays she said she was "too 
big" to ride a bike and walked it. That took two hours.

It was those two hours that Elizabeth would be sitting 
in his room, or on a chair near him, wherever he was, 
talking. 

Talking, talking, talking. 

And when she talked she breathed. 

And when she breathed, those fabulous tits moved. 

And when those tits moved he got a major boner.

On weekdays he could pay attention to his homework. And 
try to ignore her while she did her own, or read a book 
or applied makeup or whatever.

On Saturdays he had no excuse not to pay attention to 
her. Play a board game with her. Do a picture puzzle 
with her. Do SOMETHING with her for two hours.

And then whack off like crazy when Renee got back and 
Elizabeth went to her room.

He heard the front door slam, and Elizabeth's voice 
call out. 

Oh no! He wasn't ready. All he had on was the gym 
shorts he'd slept in. They were loose and baggy and 
that was BAD! Usually he found his tightest jeans on 
Saturday and folded his six-incher down into one leg. 
Then when it got firm the jeans would confine it. 

It hurt, but it didn't embarrass him. 

Then he usually put on a football jersey that hung down 
to his thighs. Then he was safe. But now, the minute he 
saw her his wang would stand at attention and poke 
straight out in his shorts! 

He put down the egg sandwich he'd been having for 
breakfast and fled for his room. 

He slammed right into Elizabeth as she came around the 
corner. She was taking her coat off and his chest 
bounced right into hers.

"OW!" she yelled. "Watch where you're going Brad."

It was happening already. He could feel the blood 
literally rushing into his tube. "Sorry," he mumbled 
and tore up the stairs, passing his sister who was on 
the way down.

"What's wrong with him?" he heard Elizabeth say as she 
saw Renee.

"He's got shit for brains," Renee said loudly. That 
meant his parents were already gone on their shopping 
trip for a new couch. That meant they'd be gone most of 
the day too. They were going to Kansas City, which was 
three hours away. Now he couldn't use them to deflect 
Elizabeth.

He sat in his room, wondering what to do. Icewind Dale! 
That was it. It took real concentration and a game 
could last for hours. He flipped on the computer and 
sat down. Dad had the wood stove going again at full 
blast. It was hot in the house. He didn't put anything 
else on.

It was some time later that he heard Elizabeth come 
into his room. He was in real trouble in an old castle 
and was going to have to play this perfectly or he'd 
lose his wizard AND his thief. He'd made his thief a 
woman - an Elven woman - and had named her Liz, because 
all women reminded him of Elizabeth. Even the character 
on the screen had the capacity to make his dick 
stiffen. He wondered if there was something wrong with 
him.

He tried to ignore Elizabeth. She knew about the game 
and usually didn't bother him, especially when there 
were red circles all over the screen. But today she 
intruded. 

"Brad? Can I talk to you about something? Brad? ... 
BRAD!!!"

The undead surrounding him attacked and his green 
circles started dimming. He was toast. There was his 
beautiful Liz, lying dead on the ground.

"WHAT!" he yelled, not without some passion in his 
voice.

"What in the world is wrong with you today?" she said, 
the hurt obvious in her voice. He hadn't looked at her 
yet.

"NOTHING!" he growled. He felt her hand on his shoulder 
and jerked away from it.

"Bradley Ray Stokes! There most certainly IS something 
wrong with you. What is it? Please? Tell me. Let me 
help. You're my friend."

Suddenly he realized he hadn't put anything on. He was 
helpless. It was going to happen. Just because of her 
voice... it was already starting. His frustration 
boiled over. He swiveled to face her. In some dim 
recess of his mind he noticed she was wearing the 
lavender sweater - his favorite. Another not so dim 
part of his mind told him to just shut up and flee to 
the bathroom. 

But the frustration took over. 

He looked at her face, her eyes, her lips and his gaze 
slid irresistibly down to her breasts. 

Yup, just like clockwork, maximum boner.

"THIS is what is wrong Elizabeth!" he shouted and stood 
up, facing her. She looked blank for a minute, staring 
at his face, not understanding, and then, naturally, 
she looked at the rest of his body. She saw it. She 
couldn't miss it, of course, but she actually jumped as 
she saw the tent in the front of his shorts. "Yes, THIS 
is what's wrong with me. Today, yesterday - EVERY DAY 
YOU ARE HERE!!! I can't control it. Sometimes it hurts, 
and I'm TIRED OF IT!"

There was a tear in his eye. Oh no! Not that, please 
not that. He got control of himself and his eyes did 
not overflow, but Liz saw them full of moisture. She 
stood there, her mouth open in a little "o". 

Then she jumped again. "Every day I’M here?" she said.

The anger had flown out of him. He'd made a fool of 
himself, he just knew it. To his amazement his dick 
started to go limp. Not all the way, but it sagged a 
good three inches. Now it was just a large bulge in his 
shorts, and not a real tent.

"Yes," was all he said.

"Wow!" she said and then, she laughed.

He turned on her, a storm on his face "DON'T YOU 
LAUGH!"

She put her hands up, warding him off and her face got 
serious "NO! BRAD! That's not why I was laughing. I was 
laughing because what I came in here to try to get you 
to do was kiss me, but I was afraid YOU would laugh at 
ME. I thought it was funny that I was all nervous about 
it because I was afraid you wouldn't want to but... I 
guess you do," she finished in an amazed voice.

Now it was Brad's jaw that dropped. "Kiss you?"

Now she was nervous. No boy had ever gotten a boner 
over her. Not that she knew about anyway. It made her 
pussy feel tingly. "Well... um... uh..." she stammered. 
"Roger Collins asked me to go out on a date with him, 
and I never went out with anybody before, and I know 
he'll want to kiss me and I didn't want to do it all 
wrong and mess it up, so I thought maybe you 'd... 
well... practice with me sort of." She took a big 
breath after such a long sentence. Man those tits were 
amazing.

In a daze, Brad couldn't believe he was nodding his 
head. Well, he could believe it, but he couldn't 
believe it was happening. 

Suddenly he was suspicious. Renee was probably hiding 
somewhere, with a camera or something and was going to 
jump out and scream or something if he kissed 
Elizabeth. "Where's Renee?" he asked.

"Oh!" said Elizabeth. "She's on her paper route. But 
you can't tell her. PLEASE. You have to promise me you 
won't tell her we did this. Please? Brad? Please?"

"Oh I understand completely," he said. "She'd never let 
us live it down. You really want me to kiss you?" He 
still couldn't believe it. 

"YES!" she squealed, then blushed. "I mean if it's OK 
with you."

He looked down at his still admirable bulge and then 
grinned "Well Duh."

She giggled nervously.

They approached each other tentatively. She had to tilt 
her head up just a fraction, and, to get close enough 
to touch his lips with hers, she had to push her 
breasts against his chest.

The kiss was magical. 

First their lips brushed. Hers were dry, and without 
thinking about it she licked them, licking his in the 
process. Then their moist lips pressed together. 

It was amazing. 
She wanted to be sucked into his body through those 
warm soft lips of his. She tasted his lips again with 
her tongue and to her amazement felt his tongue tip 
dart against hers. She moaned as she felt pain in her 
nipples. It was a sweet pain that was somehow connected 
directly to her lips. 

He on the other hand was not at all surprised when his 
cock leapt back to full rigidity. It was even better 
than he had dreamed. And she had LICKED his lips! He 
felt the soothing rush of liquid in his penis and 
realized he had leaked some cum - probably a lot, since 
it felt so good. Neither of them breathed during the 
whole wonderful thing. 

It was that fact that ended the kiss. They had to 
breathe and they broke apart gasping for air.

"Wow" Liz said in an awed voice. "I didn't know it 
would be like that. "I'm not sure I actually want to 
feel like that with Roger. Wow. Is it hot in here?" She 
was babbling as she took her sweater off. Under it she 
had on man's tank top. 

Brad stared at her breasts. 

She noticed and giggled. 

He blushed and looked away, but she said "It's OK. I 
know boys look at them. I think they're ugly, but boys 
seem to like them. Even my dad looks at them sometimes. 
HEY! What happened?"

She was pointing at his shorts. The tent was back, the 
shorts stretched tight, and there was a dark circle of 
moisture about two inches around the tip of the tent. 
Now Brad flushed beet red. "I... uh... I sort of... 
leaked while we were kissing."

"Leaked? You mean you peed your pants?" she looked 
horrified.
"NO! No! It's not pee. It's..."

Her eyes got round as she finally understood. "OH!" and 
then she giggled again.

He wasn't mad this time. "It really isn't funny, Liz."

"Oh I know. It's just that nobody ever... leaked... 
because of me before."

"Oh yes they have." he said, not realizing he'd said it 
out loud. When he saw she had heard him and was about 
to ask him about it he went on. "I have. Daily. All the 
time. Every time you come over I have to... well, it 
leaks, OK?"

"No, I don't understand. What do you mean?" She looked 
completely serious.

"You know..." he made the air jerking motions that 
every teenager understood meant that a boy was jacking 
off.

"OH!" she yipped. Suddenly she felt that sweet pain in 
her nipples again. He jerked off because of HER! It 
still felt hot and she waved the tank top around to get 
some air to her torso.

"I'm sorry," he said miserably.

"NO! Brad! It's OK. Really it is. It makes me feel... 
pretty or something. It makes me feel things... " She 
couldn't finish, but looked down at her thrusting 
mounds. 

"Brad, would you kiss me again?"

Overjoyed that she didn't hate him he embraced her. 
This time her body came against his completely as their 
lips locked. This put the tip of his hard cock right 
above where her pubic hair started and it poked into 
her. She felt weak as she realized what it was and 
kissed him even harder. Her nipples were at it again. 
She unconsciously took her hands off his shoulders and 
squeezed a nipple with each of them, and the ache 
lessened. 

But really it just transferred. 

Now she felt the tingle between her legs. 

The kiss went on and on as they figured out how to get 
snatches of air while their tongues dueled through open 
lips. When they parted she said, "I have to sit down." 
The nearest thing to sit on that both of them could sit 
on was the bed.

They kissed again. And again, and soon they were lying 
side by side, their hands sliding over each other's 
backs, shoulders, heads. Brad was in pain now, and 
finally he rolled back, groaning.

"What's wrong?" Liz asked.

"My bal... I'm in pain," he groaned. I need to go to 
the bathroom or something."

"Or something?" she asked. 

"Yeah. I need to... you know."

She gasped and her gaze went straight to his shorts. 
The stain was larger now. "You're going to... beat 
off?"

"Yeah," he groaned. "It sort of builds up and hurts 
until I release the pressure. He started to get up.

"NO! WAIT!" she yelled. He stopped and turned, puzzled. 
"Can you... do it... here? Can I... see you do it?"

Brad was actually glad at that very moment that his 
balls hurt so much or he'd have snot his wad in an 
instant. 

Without a word he skinned his shorts down and stood, 
naked, before her. She gasped again as she saw what had 
made the tent. It was red and long and hard and 
pointed. It looked angry to her. His hand closed around 
it and he stroked. There was a bunch of loose skin at 
the tip that slid back when he pulled on it and 
uncovered a shiny knob at the end. It was the knob that 
was pointed, she saw, and the skin just took its shape. 

She saw a little hole at the tip and a pearly drop of 
liquid seeped out. She knew at once it wasn't piss. It 
was thick and whitish looking. It was sperm, she 
realized. She felt a lance of tingling pain in her 
pussy and had to squeeze her nipples again. He was 
staring at her hands as her finger tips squeezed and he 
gasped. 

Suddenly she wanted to touch it. "Can I... try it? Do 
it for you?" she whispered. A big glob of the white 
stuff bulged out of the little hole when she said that. 
He stumbled over to the bed and flopped on it beside 
her. His hand came away and hers tentatively grasped 
that angry hard staff. "Oooooo," she cooed as she 
realized it only LOOKED rock hard. Actually it was soft 
and felt really good in her hand. The tip leaked more 
sperm and she realized why the stain on his shorts was 
so big. 

And SHE was making it happen! Her pussy itched now.

Brad felt the climax approaching. Her hand on his prick 
felt so wonderful he almost forgot to warn her. But he 
knew what would happen when he came. "Liz... it shoots 
out... really hard. It'll get all over your clothes." 

She heard him, but didn't want to stop what she was 
doing. Suddenly she was tearing at her tank top, 
pulling it over her head. Then she shucked out of her 
jeans and tossed both garments toward the door. 

Now it wouldn't get all over her clothes. 

Brad stared in awe at the girl pulling his pud, now 
dressed only in bra and panties. The bra showed him 
more of her breast than he'd ever seen before.

He had to ask. "Liz, could you please take your bra off 
for a minute?" She was so enraptured with watching the 
loose skin hide and then uncover his shiny knob that 
she just reached around, popped the clasp and shrugged 
the bra off. It hung up on the wrist she was holding 
his penis with, and draped across his groin.

There, displayed in all their glory, were the breasts 
he dreamed of seeing. They were very different from his 
sisters. They were round and hung away from her body as 
she leaned over him. Her areolas were only the size of 
a quarter and light pink, with a darker plainly visible 
nipple on top. Her nipples looked just about like 
Renee's, though. They looked hard and stiff. Seeing 
them was all it took to break the dam in his balls.

"Ohhhhh Lizzzzzz," he groaned. She knew something was 
going to happen and leaned closer to look. 

Just then a long rope of thick white fluid burst from 
the tip of his penis and splatted right on her right 
breast. It was HOT! She felt it run and hang from a 
nipple and immediately brought up her free hand to 
squeeze that nipple. The sperm on it lubricated it and 
she moaned as she felt the thrills shoot from the 
nipple to her pussy. Then his dick was spurting more of 
the stuff.

She managed not to get any on her face, but both 
breasts, her stomach, his stomach and a lot of the bed 
spread were spotted with it. There was so much. He was 
moaning and groaning and his hips were raising up off 
the bed. He sounded like he was in pain, but she knew 
somehow that he wasn't. 

SHE had made him feel this way! She felt so proud of 
herself. And she wanted to kiss him again. She lay down 
beside him and pressed her naked chest to his as she 
sought his lips. That felt good too, even with the 
slippery cooling sperm all over her. Her pussy itched 
fiercely and she wanted to rub it.

They snuggled and kissed for ten minutes before Brad 
lifted his head and looked at the clock. "Hey, we've 
got to get cleaned up. Renee will be back soon."

"I don't think so," said Liz. "It snowed last night and 
there's eight inches on the ground. It's going to take 
her hours to get around her route."

Brad jumped up and peered out the window. A thick layer 
of white covered everything. Normally he'd have been 
overjoyed, thinking of going out in it. But now he was 
overjoyed because it would give him just a little more 
time with Liz. "Come with me," he said, grabbing her 
hand. 

They ran to the bathroom and he turned the shower on to 
hot. He looked at her, and with only a little blush she 
bent to remove her panties. Then she took off her 
socks. They got into the shower together, and it only 
seemed normal to wash each other. 

She washed him first, running her hands over his chest, 
feeling his pecks and then kissing him as she rubbed 
her body up against his. Then he ran his soapy hands 
over her, lingering at her breasts, teasing the 
nipples. Liz felt the fire begin to build in them and 
run to her pussy. Before he could touch her between her 
legs she was against him, kissing him deeply. 

His dick rose again, between her legs, and pressed in 
between her labia. Now something WAS rubbing her pussy, 
and it felt WONDERFUL. She didn't want it to stop. But 
he was turning the water off. They got out and he gave 
her a towel. They hurriedly dried off and then she 
picked up her panties and socks and they left to go 
back to his room.

"Brad?"

"Yeah Liz?"

"What does it feel like... when you... when you cum?"

"Gosh. I don't know how to describe it. I suppose it 
feels a lot like it feels when YOU cum. Why don't you 
tell me about that and we can compare."

She was silent for a few seconds. "I... I'm not sure I 
ever HAVE cum." she said softly. 

"Don't you... you know... rub yourself?" He assumed all 
girls did. He knew Renee did because he'd spied on her 
one time and saw her doing it on top of her covers.

"Oh no. I mean, my mom told me when I was little that 
it was very bad to do that, and that I'd hurt myself 
and maybe even go blind if I ever did it."

Brad was stunned. He tried to think about what his own 
life would have been like if he couldn't jack off. 

He'd have just died. That's all. He'd have croaked by 
the time he was twelve. 

But he'd heard the same stories. Not from his parents - 
they hadn't said anything at all to him - but from 
other kids. He knew it was bullshit. 

"I don't think that's right at all," he said. "I mean 
I've been beating my meat for years now, and I haven't 
grown any hair on my palm, or gone blind or crippled or 
any of that stuff. You should try it. It feels really 
good."

"I know it does," she blushed a little. "When we were 
in the shower and your... cock... was touching me 
there, it rubbed and it felt really, really good." 

There was more silence. "Could we do that some more?"

Brad's head was spinning. He'd never actually fucked a 
girl. He'd seen it on lots of videos at his friend's 
houses, but he'd always been too shy to try anything 
with a girl. Not that what she was talking about was 
actually fucking. But it was close, and he remembered 
the feeling too. 

"Yeah!" he said tightly. "I think I'd like that too."

"I can see that?" she said, amusement tingeing her 
voice. He hadn't even felt his cock go hard. But it was 
at full measure again, standing out proudly. They 
embraced and began a slow sort of dance, during which 
they kissed hotly and his cock rubbed along the furrow 
of her pussy. He felt her get slick, and his cock slid 
through much easier. She was breathing harder now. But 
there was only so much pressure that could be applied 
in that situation.

"I have an idea," she said, panting. She walked him 
backward until the back of his knees hit the edge of 
the bed. Then she shoved him in the chest and he flew 
backward onto the bed. She leapt after him and landed 
straddling his hips. She sat on his knees and bent over 
to jack his cock a few times. "I love the way it feels" 
she said as she watched his glans play hide and seek 
inside his foreskin. Then she lay it down on his 
stomach and scooted forward until her pussy lips 
straddled the firm underside of his cock. She let her 
weight down and pressed his organ into his abdomen. 

"Mmmmmmm" she said as she slid her pussy forward along 
his tube. "That's better."

She started making long slow movements, dragging her 
pussy mouth along the length of his dick. He'd never 
felt anything quite like it. Knowing what was doing it 
started his dick leaking again and soon there was a 
puddle of precum on his stomach. Liz was obviously 
having a good time too as she made her movements more 
rapid. She leaned over to kiss him just as she scraped 
her pussy forward and, for the first time, her little 
unused clitty made contact with his knobby prick. Her 
head whirled as stabs of pleasure streaked through her 
young body. 

"OH!" she moaned. "Ohhhh Ohhhh Ohhhhhhhhh". She leaned 
back up, but not far enough to break clitoral contact, 
and suddenly her breasts were hanging right in Brad's 
face. He couldn't resist. His head came up and he 
gobbled one nipple, sucking it into his mouth. It was 
hard and firm, and he was able to get a grip on it with 
his teeth so it couldn't slip right back out of his 
mouth.

That was the fateful moment. Already in constant and 
almost violent pleasure from rubbing her clit over his 
wonderful cock, the added stimulus of having her nipple 
suckled for the first time caused her to fall headlong 
into her first real climax. She felt it start in her 
pelvis as an almost electric tingling, which rapidly 
spread throughout her stomach, up to her breasts and 
then somehow into her brain. 

Her lunges became frantic. She bent forward more, to 
keep his mouth in contact with her aching nipple, and 
that lined her pussy up with the length of his cock. As 
she lunged back toward his balls, the head of his cock 
slid neatly into her open pussy hole and in one violent 
lunge she impaled herself halfway to his balls. The 
flash of pain associated with her torn hymen came right 
in the middle of her orgasm, which she now realized in 
some small part of her brain was in fact an orgasm. She 
felt the tearing as pain, but assumed it was part of 
what was happening to her - part of the orgasm. And, in 
truth, the pain lasted only a few seconds. Then the 
fullness of her vagina registered, and her nerves 
identified the foreign body as something hot and firm 
and she realized what had happened. 

She gasped "OH!! BRAD!! IT'S IN MEEEEEEEE. YOUR COCK 
WENT IN MEEEEEEEE. OH IT'S INSIDE MEEEEEEE. OHHHHHH 
SHIIIIIIITTTT." Her gyrations got even wilder as she 
instinctively wormed her pussy further onto his stiff 
rod. The pleasure of being filled as it went deeper and 
deeper into her was indescribable.

Brad too knew what had happened. He'd been happily 
sucking on her juicy nipple when sudden heat surrounded 
his cock. Then his cock was squeezed like nothing he'd 
ever felt before. Then the tip of his cock reached her 
cervix and happened to be lined up to nudge right into 
that opening. It wasn't quite long enough to penetrate 
iclear into her womb, but those cervical lips were 
spasming with her orgasm and they nibbled at the head 
of his cock. Truth to tell he'd been close to squirting 
anyway, but the nibbling on the head of his cock made 
him lunge upward and THAT popped the tip of his cock 
into her womb. His penis fired immediately. 

He felt the stream of cum as it left his balls and 
raced through his penis. The sweet release flooded his 
consciousness as it rocketed out of the end of his 
prick... and straight into her womb. That jet was 
followed by six or seven more and they were the type 
that would have indeed shot two or three feet in the 
air. Brad went crazy, grunting and huffing and puffing 
and thrusting.

Liz felt the splats of hot juice in her womb and found 
out that an orgasm can be even better. 

Little did either of them know there was an egg 
floating around, floating in a sea of sperm. 

They all attacked. 

Only one got through.

Brad and Liz both started awake. They had lain there, 
catching their breath and had dozed off, so comfortable 
they were cuddled together. Brad checked the clock and 
panicked. If Renee wasn't home already she would be 
soon. Frantically they both leapt out of bed, grabbed 
their clothes and dressed. Brad put on a pair of jeans 
and T shirt. He had just finished getting his sheets 
started in the washer when he heard Renee come in. 

By now Liz was sitting on the couch, curled up with a 
book. 

Renee stomped off all the snow on her legs, grousing 
about the miserable weather. Liz was just sitting 
there, in the light of the lamp, looking at her. Renee 
couldn't put her finger on it, but something was 
different. "What happened to you?" she said as she took 
off her parka.

"What do you mean?" said Liz, nervously, thought Renee.

"You look... I don't know... different. Did you change 
something?"

"No. I don't understand." said Liz. She was beginning 
to get worried.

"I can't really explain it." said Renee. "You look... 
relaxed or something. But that's not the right word. 
You look happier or more relaxed or something."
"You must have frostbite of the brain Renee." said Liz 
doubtfully.

"Well If I've got frostbite of the brain, then you've 
got it too. Or do you always read books upside down?"

Liz started and realized Renee was right. She WAS 
holding the book upside down. "Oh, I put it down when 
you came in and I guess I picked it up wrong or 
something. How was your paper route?" 

It was unashamedly an attempt to get Renee off of where 
she was headed. And it worked too. Renee went into a 
rant about how miserable the weather was and how it 
didn't pay enough and nobody appreciated her. But she 
forgot to probe any more into why Liz looked different.

The following weeks brought another change too. 
Everybody in the family noticed how Brad's whole 
attitude about life had improved markedly. He didn't 
snarl at other family members any more. He offered to 
do his chores, instead of being made to. He was even a 
lot nicer to Elizabeth from what they could tell. He 
was teaching her how to play that video game he was so 
wild about. Every time Renee went out on her paper 
route they'd have a tutorial session.

Of course that wasn't really what was being "tutored". 
And the reason Brad was so gloriously happy was that he 
was getting his rocks off in Liz almost every day. As 
soon as they were in his room they went at each other 
like wrestlers and soon he was rutting away in her 
pussy, dumping yet another potent load of his heavy 
sperm in her clutching cunt. And she was so happy with 
the way things had turned out that she turned Roger 
down for his offer of a date. She didn't tell anyone 
that the love of her life was Brad, but he was. Brad 
felt the same way.

Which was good, because there were trials to come. 

Elizabeth hadn't been all that regular in her periods 
anyway, so when hers skipped she didn't think much of 
it. Three months later, though, she couldn't ignore her 
condition any further. 

The shit DID hit the fan. Elizabeth's father actually 
showed up at Brad's house WITH a shotgun, saying there 
WAS going to be a wedding. 

While Brad's mother went into hysterics his father 
calmed the hunter down and they worked something out. 
It was agreed there would be a wedding, just not this 
year. Or probably next year and maybe even the year 
after that. One of the youngsters had to agree to go to 
college while the other worked to support them. They 
were not to see one another in any way shape or form 
until after the baby was born. Then and only then would 
they be able to care for the baby together, when 
possible. Brad was expected to be actively involved in 
the raising of the child. 

No one asked him if he agreed, but he thought it was a 
pretty good plan. 

But his supply of pussy was cut off, and it was hard on 
him. He went back to jacking off.

Renee wouldn't talk to Brad at all for over a month. He 
had KNOCKED UP her best friend! 

And she hadn't even known what was going on!! 

That was really what pissed her off. Well, some of it 
any way. What really pissed her off was that she 
thought Liz would have said something about losing her 
virginity, or that she was thinking about doing it with 
a boy or SOMETHING. 

But she hadn't. 

There had been a secret - at LEAST one. And she blamed 
Brad for that. It never occurred to her that Liz might 
not want her to know for the same reasons Brad didn't. 
It almost ended their friendship. The first time they 
saw each other after the news broke they got in a 
horrible fight. But their friendship was years long and 
tougher than that. 

"I KNEW there was something new about you. I KNEW it." 
fumed Renee. 

Liz laughed, and that made Renee even madder until Liz 
explained. "Remember that Saturday when you had to do 
your route in 8" of snow? Remember how you came in and 
wanted to know what I had changed? Remember?"

And Renee DID remember. "You mean...?"

"Yes. That was the very first time. It just sort of 
happened. I started it actually. I was thinking about 
going out with Roger and asked Brad to teach me how to 
kiss." She sighed. "He's a REALLY good kisser Renee. 
You have no idea."

"Of COURSE I HAVE NO IDEA" growled Renee. But for some 
reason she felt better knowing that Liz had started it. 
Now why was that, she wondered.

"And then he was in pain and I helped him, and that 
caused us to have to take a shower and then I wanted to 
rub against him and then it accidentally went in and... 
it just happened." Liz said in a rush. "But I couldn't 
tell you because you'd have told on us .. or at least 
give us a hard time. You know you WOULD, Renee."

When she thought about it, Renee agreed that that's 
exactly what she would have done. That made her feel 
better too. Of course she wanted all the gory details. 

And Liz shared them. 

She'd wanted to talk about it with Renee anyway, and 
now, at last, she could. She ended up saying "And now 
we can't even see each other for six more months and 
it's not fair." She started crying. 

Renee comforted her quietly. She had to do it quietly. 
Her whole body was in a roil of turbulence. The gory 
details had gotten to her. She recognized immediately 
the feelings that Liz had described, because she felt 
them too. Her nipples had always been super sensitive 
and now they were aching. And her pussy was itching 
too, and she couldn't wait to get alone so she could 
get off. She knew, of course, what an orgasm felt like. 
She'd had dozens and dozens of them, and had thought 
Liz had too, but that was one thing they'd never 
thought to share. But her orgasms didn't feel as 
intense as those that Liz described. 

Of course she'd never had an orgasm with her pussy 
wrapped around a hard cock. She was smarter than that. 
All she had to do was look at Liz’s swelling belly to 
know she was right to stay clear of those things. 

But she did wonder what it would be like.

Now Renee was the one in the family who was surly and 
hard to get along with. Every time she saw her brother 
she couldn't help but look at his crotch, where lay the 
monster that had attacked her best friend. Well, 
`attack` wasn't the right word. That was part of the 
problem. Liz had said she couldn't wait to get him 
alone and get that monster in her pussy so it could 
squirt some more hot jizz in her. 

Now Renee had a constantly horny pussy to put up with 
and she had to start wearing bras because any material 
sliding across her nipples made it so bad she had to 
find a place and rub herself to climax. The worst thing 
was that one night she stuck her fingers so far up in 
her that it hurt, and then there was blood on her 
fingers. 

She'd actually busted her own cherry for pity's sake. 

It was driving her crazy thinking about what they had 
done, and what SHE hadn't done. She even started 
looking around for a boy to officially take her 
virginity. But she couldn't find a way to get on the 
pill, and she didn't trust condoms. Actually she didn't 
trust a boy to actually use one, but it was all the 
same. 

AND she couldn't talk to Liz about it either. She'd 
never liked going to Liz's house. Her parents were such 
weirdoes. They were so strict that when she was there 
SHE was expected to obey all the same rules of life as 
Liz was. They jumped her about her language and even 
kicked her out one day for wearing shorts with a hole 
in them. Told her to come back when she knew how to 
dress decently.

So it was the night her parents were at a party and she 
and Brad were the only ones home. She got out of the 
shower, wrapped her head in a towel, and headed back to 
her room for bed. She'd rubbed off in the shower, but 
the release hadn't been very satisfying. As she passed 
Brad's room she glanced through the slightly open door 
and stopped, rooted to the floor. 

He was lying on his bed, naked, with one arm behind his 
back. 

His eyes were closed and he was slowly jacking his hard 
cock with his other hand. No urgency, just playing with 
himself. 

He was playing with the cock that had ruined her life. 

She mistook the ball of heat in her belly for anger, 
instead of the lust it was, and barged into his room. 
She was on him before his eyes even came open. She 
leapt through the air, crashing down on his thighs and 
pinning his shoulders to the bed, screaming a primal 
animal growl. 

His eyes flew open and his hand left his cock. Her 
fists were beating at his chest and she was horrified 
to find she was crying. He wasn't fighting back. He was 
just staring at her. His eyes flipped quickly to her 
breasts, which were jiggling around as she flailed at 
him, but then came back up to her face. His hands went 
to her waist and held her. She still felt that ball of 
fire in the pit of her stomach. She screamed that Liz 
was her best friend, and how could he have done that to 
her best friend. How could he have done that to Liz... 
she 
collapsed, sobbing into his neck... 
and not her. 

She shuddered as she said it - finally admitted it - 
finally admitted that she lusted for her own brother. 
As she said it she felt his erection pressing against 
her stomach.

Brad had been surprised by her attack, but had almost 
instantly known what was really going on. She was wet. 
She was drenched where her pussy touched his penis, and 
it wasn't from her shower. He had plenty of experience 
with exited women now - well, excited woman - and he 
knew she had been watching him. She raised her head 
enough to look at him. Her eyes were still leaking 
tears and she cried "Oh Brad."

Some dim ancestral knowledge, passed down through genes 
he'd never even thought about suggested he should do.

Brad rolled his sister over, landing between her wide 
spread thighs. He couldn't just take her, even though 
he thought that was really what she wanted. She had to 
be a willing participant or it would ruin everything 
for both of them. Kneeling over her he saw her breasts 
again, with their huge areolas and thick stiff nipples. 
He leaned down and sucked the whole areola into his 
mouth. His tongue slathered all around it, running over 
the nipple, but also washing the skin around it.

Renee found out what those puffy areolas she hated so 
much were good for. the feelings he was generating with 
his mouth and tongue were like huge jolts of magical 
energy zapping her whole body. She flopped beneath him. 
Her hips thrust up off the bed. He kissed his way up to 
her neck and she shivered as he nuzzled her there. Then 
he kissed her lips. He WAS a good kisser. She melted. 
Her hips fell back to the bed and she lay there limply 
as he almost fed on her mouth. 

Now it was her pussy that was yelling at her. The itch 
was there. It was that itch she had been trying to 
scratch when she had popped her own cherry. He raised 
his head and just looked at her.

"Please?" she said softly "Please Brad?"

"Please what?" Brad said just as softly. He kissed her 
gently on the lips. "Please get off? Please leave you 
alone?"

"No" she whispered. 

That was enough for him. With no further ado, no 
additional foreplay... and no condom... he reached 
between them, fisted his rock hard cock, and fed it to 
his little sister's cunny. He didn't ram it in, but he 
pushed it in steadily and all at one slow-motion lunge, 
burying himself in her to the balls. Then he stopped. 
One of the things he had learned with Liz was to go in 
all the way and then make little circles. That massaged 
her clit and cervix at the same time and drove her 
crazy. 

It did the same thing to Renee. 

Her eyes went wide and she took in a huge breath of air 
as she felt herself being stuffed with prick meat for 
the first time. She was going to groan - it did hurt a 
little, she was stuffed so full - when his little 
circles began. Her groan turned into a sighing moan, 
"Ohhhhhhhhhhhhh." 

All pain fled and her hips went into overdrive of their 
own volition. Brad, by now, was an expert at riding 
such hips and he rode like a life-long cowboy. 

He wanted Renee to have an orgasm that she'd remember 
for the rest of her life.

She did. She felt like the top of her head was going to 
blow off. Her face got red and she could feel her heart 
pounding in her chest, trying to tear itself free and 
hop around the room with joy. Her pussy spasmed and 
that itch, that horrible awful itch just stopped cold 
as her pussy rippled all around that sweet invading 
column of brother bone. She recognized the onset of an 
orgasm, but it wasn't like any orgasm she'd ever had 
before. 

She was a gusher, though she hadn't known it. Her 
juices all but spewed out around his invading dick, 
soaking her thighs, his pubes and the sheets. Brad 
thought she had peed on him at first, but it didn't 
smell like pee. He knew she'd cum and now his own 
urgency had caught up with him. 


He had to pull out. 
That was something he'd learned the hard way. 

"Renee, honey?" he said soothingly. She was still 
writhing under him, and her pussy was still milking 
him. She was having a long orgasm. "Renee, baby I've 
got to pull out. I'm gonna squirt, honey and I can't 
stop it." 

Her eyes slowly opened, still a little glazed and she 
panted. "Just this once. Just this once I want to feel 
it all. Just this once and we'll never do it again." 
And, just to make sure, her legs came up and around his 
back, to hold him in.

Brad groaned. He loved coming in a woman, feeling his 
sperm shoot out into a hot, fertile woman. It was 
natural to feel that way. Men were wired that way. So 
he gave in and gave her what they both wanted. 

He came like a river. 

It wasn't quite as hard or as much as that first time 
with Liz, but it was a close second. Forceful ropes of 
sperm-laced semen lanced into her belly over and over 
again. As she felt the first jet of his sperm dump into 
her Renee let her legs fall back to the bed and she lay 
there limply, feeling him pouring his seed into her. 

She had to agree with Liz, that was something you could 
get no other way. Something that made you feel 
complete, fully alive. She hoped like crazy she 
wasn't fertile right now.

They made love three more times before their parents 
got back home. Now SHE had a secret to keep from 
Elizabeth.

But, of course she couldn't. The first time Liz saw her 
after she'd fucked her brother Liz looked at her 
speculatively and said "What have you been doing behind 
my back?" Renee tried to bluff, but it didn't work. "I 
see what you meant when you said something was 
different about me" Liz told her. "I don't know if 
anybody else will see it, but I'm here to tell you it's 
written all over your face. Who was it?" 

This made for a tense moment, but Renee decided to get 
it over with. "Well, it was YOU who kept talking about 
what a good kisser he was, and how WONDERFUL it felt to 
have him shooting off inside you and on and on..." 
Liz's eyes went wide and her mouth went into an "o". 
"You mean... BRAD?!" 

"It's not like that," Renee protested. "It was really 
an accident. You see I was going back to my room 
and..." she stopped as Liz started laughing. "What?" 
she said.

Liz couldn't talk from laughing so hard. Hearing Renee 
claim it was an accident brought back the whole memory 
and she knew Renee was telling the truth. But it was 
still funny to hear her use the same words Liz had 
used. Renee suddenly got it and started laughing too. 

Then she stopped. "He came in ME too," she said. 

Liz stopped laughing too.

Hope springs eternal, they say, and this time they were 
lucky. Renee had her period right on time. She was at 
once relieved, and at the same time saddened. She'd 
thought a lot about whether or not her brother's seed 
had taken root in her belly, and wondered what it would 
be like to watch that belly swell, like Liz's was. 

She realized she was actually a little disappointed 
when she bled as usual. It occurred to her that she 
could always try again next month. All she had to do 
was "forget" to put a rubber on his wonderful cock 
before she sat on it. She was his surrogate "wife" for 
the time being, since he still couldn't see Liz. 

But she was getting used to having all the hard cock 
she wanted and when the baby was born she was afraid it 
would stop. Lately she'd been spending most nights in 
Brad's bed, his boner stuck up in her while they slept 
and she'd miss that a lot. She still didn't like the 
idea of letting some boy stick it in her, but she might 
have to resort to that.

She couldn't, though. 

And... Hope DOES spring eternal. The baby was born and 
raised just about as much in Brad's home as it was in 
Liz's. When Liz's parents saw them together with their 
child, and saw that Brad was trying to learn and be a 
good father, they lightened up a little. He got a job 
and started saving his money. He got straight 'A's as 
usual and it looked like he could get a full 
scholarship to several good schools. He didn't go out 
with other girls. 

Of course he didn't need to. He had all the sex he 
could handle, and then some. Liz and Renee decided it 
was only right to share him. Several times they shared 
him in the same room at the same time. 

They talked about sharing him for a lot longer than the 
next two or three years. Renee started with a tutor and 
went to summer school so she could graduate with Liz 
and Brad. And as they entered their senior year the 
girls made further plans. The wedding had been set for 
the evening of graduation day, since most of the 
extended family would be there anyway. The home Brad 
and Liz planned to make would need a nanny, so that Liz 
could work while Brad went to school. Renee could take 
some night classes. It would work out. 

They told Brad and he was overjoyed.

In March one week to the day after her last period had 
stopped, Renee snuck into Brad's room, as usual. It was 
cold and she was glad for his warmth as she slipped 
into bed with him. He had fallen asleep, but woke up 
quickly, hugging her and telling her he was glad she 
was there. 

As usual, the minute he felt naked skin against him he 
was hard as a rock. They kissed and cuddled for a while 
and she stroked him to make sure he was nice and hard. 
Then, without giving him time to clothe himself in 
latex, as was their custom, she straddled him and 
settled down on him. "Renee?" he said.

"Shhhh," she whispered. "I'm tired of rubbers. I want 
to feel it again, like that first time." He was always 
a good lover. He knew her boobs better than SHE did and 
could play them like an instrument. She loved her tits 
now. But knowing he was going to squirt into her 
unprotected, made him a tiger. She thrilled to his 
roughness, not even trying for her own orgasm, just 
wanting to feel that hot wet flood deep inside her.

He didn't disappoint her. In fact, he didn't disappoint 
her three times that night. She smiled as she finally 
drifted off to sleep, Brad's cock still plugged into 
her, keeping all his wonderful sperm up inside her. 

She and Liz had made sure the apartment had room to 
make a nursery big enough for TWO babies.
