                         Helping Out Sis
                         An Erotic Story

     Michael Fisher (Mike to everyone but his 5'th grade 
schoolteacher) sneaked a peek into the partly opened door of his 
big sister's bedroom.  At 10, the boy was just starting to get 
interested in girls, and lately had developed a habit of spying 
on his big sister (Big sister being relative.  Mike actually 
outweighed his older sister by 5 pounds.  Judy was only 10 months 
older than mike.)  In spite of their differences, Mike loved his 
big sister, and would have done almost anything for her.  Today, 
the boy was in luck.  Judy had just returned from the shower, and 
was laying naked on her bed, reading.  For several long minutes, 
Mike looked at his sister's developing body, taking her in, from 
her lightly rounded little ass, to the pert little bumps that 
were, at the moment, pressed into the furry bedspread.  Each time 
the little girl shifted position, Mike would get a glimpse of 
another part of her delightful young body.  Soon, the boy's cock 
was tenting the front of his shorts.  Mike was wearing shorts, 
and not much else, as it was mid-summer, and 85 degrees outside.  
For somewhat the same reasons, Judy was in no hurry to get 
dressed, and swelter in her clothes again.
     After reading for about 15 minutes, during which time Mike 
was unable to draw himself away from the door, Judy started to 
get bored with the book she was reading, and turned over.  As she 
did so, Mike was treated to a full frontal view of the little 
girl's pert young tits, and the light fuzz that topped her almost 
hairless little snatch.  This unexpected delight, caused the boy 
to suck in his breath with a slight gasp.
     Judy heard her brother's intake of breath, but carefully 
acted as if she hadn't noticed.  Continuing her motion, the girl 
spread her legs, and lay on her back, giving the boy a complete 
view of her open little cunt, now starting to drool cream at the 
thought of turning on her little brother.  Ever since the little 
girl had started having periods, she had been dreaming about 
putting on a show for a man, and possibly even getting fucked.  
Her mother had explained to both the children when they were 
young, about how babies were made, so Judy knew what happened.  
It was scary, thinking of having a baby, even though it was also 
exciting.  So Judy mainly dreamed, not daring to actually try 
anything.
     Now, knowing her little brother was sneaking peeks at her 
naked body, turned the little girl on.  She had never thought of 
her little brother before as a possible sexual partner or 
boyfriend, but the kid shared her good-looks, was bright and 
friendly, and in general, was all that a girl could ask for.  
Judy decided to try and "make-out" with her brother.  They 
couldn't actually fuck, as she didn't want to get pregnant, but 
there were lots of things two horny kids could do without 
actually fucking.  Judy thought it over, all the time carefully 
turning her body to give her little brother fresher and even more 
tantalizing glimpses of different parts of her developing young 
body.

     How could she get the little boy into her room, with both of 
them naked, without seeming like a slut?  He was obviously 
interested, and from the shiny head of the oversized-for-a-10-
year-old cock that was peeking out of the top of the little boy's 
shorts, well equipped for the job.
     A slight ache in her neck, as she tried to keep the boy in 
view, in the mirror, gave Judy the Idea she had been searching 
for.
     "OW!" said Judy.  "Aughh!  Oh that Hurts!"  The little girl 
twisted as if in pain, and lay face-down on the bed, trying to 
reach her back as if she were in agony.
     Mike had been enjoying the show, when he saw his older 
sister seemingly strain her back, and collapse onto the bed.  
Worry about his sister being hurt, overcame his fear of being 
caught peeping.  "What's the matter, Judy" he worriedly inquired.
     "My back.  It's killing me.  I think I got a cramp."  Judy 
hammed it up for all she was worth.
     "Shall I go and get Mom?"
     Their mother was the last person Judy wanted to see at the 
door right now, maybe her handsome father but. . . Judy shut the 
thought off with a snap.  "No.  It'll relax in a minute," she 
explained.  "Maybe you could help by rubbing my back."  Judy 
carried on with her plan.
     Tentatively, Mike approached his beautifully naked big 
sister.  He was so excited, at the thought of actually touching 
the little girl's naked skin, he didn't notice the girl's 
movements that belied her "cramp."  "You mean like this?" he 
said, starting to massage the little girl's shoulders.
     "Yes, but farther down" directed Judy.
     Dutifully, Mike started massaging "farther down," until he 
was rubbing the middle of the girl's back.  "How's that?" he 
inquired.
     "Fine, but harder," requested his sister.
     Mike was already rubbing as hard as he could, the little 
girl kept being pushed away, when he tried to do it harder.  He 
explained this to his sister.
     "Why don't you get on top of me, and do it."  Judy almost 
snickered, as she realized how well her plan was working.
     "Uh Judy," warned Mike, "you're naked, and I. . ."  How 
could he tell his innocent sister that he was sporting a hard-on 
for her.
     "That's OK.  I don't mind.  Why don't you take your shorts 
off too, if that's what's bothering you?"  Judy was so proud of 
herself for thinking up that line, she almost burst out laughing.
     "But Judy, I've got. . . "  He couldn't say it.
     "So you've got a hard-on.  Big deal!  Just don't try to 
stick it in me.  OK?"  Judy hid her face in the pillow, so her 
little brother couldn't see her expression and spoil everything.
     Mike couldn't believe his luck.  His big sister didn't mind.  
Now he could get on top of her, and feel his big sister's body 
all over, under the pretense of giving her a back-rub.  It was 
almost too good to be true.  Hurriedly slipping out of his 
shorts, Mike climbed on top of his sister, and started to rub her 
back.

     Judy was pleasantly surprised.  The little boy was good!  He 
pressed into the small of her back with his fingers, and began 
giving her a massage that threatened to put the little girl to 
sleep.  After working a while on her back, the boy began running 
his hands up and down the girl's sides, and then he began rubbing 
her shoulders like an expert masseuse.  Judy didn't know it, but 
she had picked the perfect thing.  Mike had been learning to give 
his mother massages, under the direction of his father, because 
the man was unable to treat his wife to the long hard massages 
that she so loved, so he had started enlisting the aid of their 
son.  Mike's arms had been growing stronger, over the past few 
months, and he was getting to be very good at it.
     Presently, Mike had somewhat of a "big" problem.  His cock 
was banging against his big sister's cute little butt, and 
leaking clear slippery fluid down into the crack of the little 
girl's ass.
     Judy enjoyed the feel of her brother's cock sliding against 
her rounded little ass.
     "Judy.  My cock is getting in the way," said Mike.  "Can I 
put it down between your legs for a minute?"  Mike held his 
breath, waiting for his big sister to answer.
     "Well, OK.  Just for a minute.  Just don't get any of your 
cum in me," agreed Judy.
     Mike continued rubbing her back, while he started sliding 
his big cock down between the girl's legs.  The boy kept on 
sliding his cock past the clenched lips of his big sister's 
vagina.  Each time the tip of the boy's cock slipped by the 
entrance to his sister's vagina, he would push the head in a 
little, and let a bubble of slippery liquid lubricate the girl's 
little hole.
     Judy felt her brother pressing the head of his prick into 
her now slippery hole.  "Stop it!" she said.  "You almost went 
inside me that time."
     Mike resumed sliding his cock past the lips of his big 
sister's vagina.  "Don't you like it?" he inquired.
     "Yes, but we shouldn't," she replied.  Still, Judy began 
working her hips in time with the sliding of her little brother's 
cock.  She enjoyed the slip-sliding feel of her brother's penis 
rubbing against her pussy lips.
     After waiting a bit, Mike once again pushed the head of his 
cock against the opening to his big sister's vagina.
     This time, Judy didn't stop him, as Mike let several big 
spurts of pre-cum lubricate his big sister's hole.
     "You aren't cumming inside me, are you?" inquired Judy, 
worriedly.
     "Just making it easier for my cock to slide, while I rub 
your back," reassured Mike.
     The next time that Mike felt the tip of his cock reach his 
sister's hole, he pushed in a little harder.  There was a popping 
sensation, and the little boy felt a ring of muscles slip over 
the head of his prick.

     "You little bastard.  You slipped your cock inside me, 
didn't you."  There was no heat in the little girl's accusation, 
and she didn't pull away.
     "I've just got the tip in," lied Mike.
     "It feels like more than just the tip," grumbled Judy, but 
said no more, as she relaxed into her brother's continuing 
backrub.
     Mike continued to rub his sister's back.  Only now, he was 
sliding the tip of his cock in and out of the lips of his big 
sister's hole, enjoying the sensations, each time the muscles of 
the girl's vagina snapped around the head of his prick.
     Judy knew what her brother was doing, but was enjoying 
herself too much to object.  After a short while, Judy started to 
push back at her little brother.  More and more of the little 
boy's cock slid into his big sister's belly, until the head of 
the boy's prick rested against his big sister's unbroken hymen.
     "You'd better not knock me up, you little bastard," said 
Judy, pushing back at her little brother.
     Mike pushed his cock in and out of his big sister, until he 
knew he was close to cumming.  "Stop Judy!" he said.  "I'm almost 
ready to cum."
     "Don't cum in me!" the girl cried.  "I don't want to get 
pregnant!"
     "Just wait," he continued.  "No don't pull off.  Just hold 
on.  If you pull off, I might cum inside you before you get all 
the way off.  Just hold still.  Don't move!"  Mike grit his 
teeth, and fought down the sensations that almost had him 
squirting his seed all over the inside of his own sister's tight 
little vagina.  Shortly, the boy felt a slight releasing 
sensation in his cock.  He didn't know if what he released inside 
his sister was cum, or just more lubricating fluid, but his prick 
was still hard, and the boy no longer felt like he was going to 
ejaculate sticky white baby-juice all over the inside of his big 
sister's tight little belly.
     "Ooooh.  OK," he said.  "We can continue now."  With this, 
Mike started fucking his sister, sliding his cock all the way up 
to her unbroken cherry, and all the way back out.  Back and 
forth.  Back and forth.  Mike was really fucking his sister now.
     After a while, it got to be too much for Judy.  "Stop," she 
said.
     "Huh?" Mike asked.
     "I want to turn over, so that we can do it right," she 
explained.
     "Are you sure?"  Mike wanted to know.
     "Uhuh.  If we are going to fuck, let's do it right."  With 
this, the little girl turned over, and placed her brother's big 
cock against the opening to her vagina.  "Now push," she 
commanded.
     Mike pushed, and his cock slid all the way up inside his 
sister's belly with a rush.  There was a snapping sensation, and 
Judy felt her hymen break.  Then the little girl started to 
climax, knowing that she had her own handsome little brother's 
big baby-making cock stuck all the way up inside her tight little 
belly, where it belonged.

     "Horny little bastard.  You wanted to fuck me.  Well fuck 
me!" she cried.  "You'd better not cum inside me though.  I don't 
want to get pregnant."
     Mike felt like he was in heaven.  He slipped his cock in and 
out of his sister's belly, enjoying the feeling of his sister's 
vagina squeezing on his engorged penis.
     Judy loved it.  The girl hadn't realized how good it would 
feel to be fucked.  Soon, Judy found herself in the throes of a 
another even mightier climax.  "Cum.  Cum.  Cum.  I'm going to 
cum!" she panted.
     "Judy don't," warned Mike.  "You're going to make me cum 
inside you."
     Judy was too far gone to stop.  The climaxing young girl 
wrapped her arms and legs around her brother in a death-grip, and 
worked even harder.  "Unh.  Unh.  Do it," she encouraged, not 
letting him go.  "Squirt your cum in me.  Knock me up."  Judy 
couldn't believe the words she heard coming out of her own mouth.
     Mike couldn't help himself.  The boy began ejaculating big 
greasy ropes of thick white baby-making sperm right up inside his 
own sister's tightly squeezing little belly.  Rope after thick 
sticky rope of incestuous sperm squirted into the spasming belly 
of the little 11 year old girl, until both siblings were panting 
with exhaustion, and Mike had emptied his balls into his sexy big 
sister's receptive young womb.
     "Sorry sis," he apologized, "I couldn't help it.  Why didn't 
you let me go?"
     "I couldn't" replied Judy, still panting.  "It felt so good, 
feeling you squirt that white stuff that make babies up inside my 
belly, trying to knock me up."
     Mike had to agree.  It had felt soo good.  "Are you mad at 
me?" he asked.
     "No, mainly, I'm mad at myself," replied Judy.
     "Why?  I thought you said you liked it."  Mike was confused.
     "I did.  That's why I'm mad at myself.  When I think of all 
the wasted time, when we could have been doing this, I get mad."
     "You mean you'll want to do it again?"  Mike couldn't 
believe his luck.  "I thought you were scared of getting 
pregnant."
     "I am, a little.  Still, even the thought, that I might be 
carrying your baby inside my womb, is kind of sexy.  Don't you 
think?"
     Mike had to agree.  The thought of his baby, growing inside 
his big sister's cute little belly, making it bulge, already had 
the boy's penis swelling, and wanting more.
     After a bit, the relaxation of after-sex letdown lulled Judy 
into falling asleep right where she was.  Shortly, Mike was 
napping alongside his big sister also.
     It was in this position, the two siblings sleeping, Judy 
with her brother's sticky white sperm slowly welling out of her 
newly stretched little hole, and dribbling down her thigh, while 
a matching glob of white seeped from the end of the little boy's 
prick, that their parents found them, about a half-hour later.  
But that's another story.
