The Wrong Sister
An Erotic Story
This morning when I got up to take a pee and passed my son's
bedroom, I heard him grunting pretty hard, so I figured he was
fucking his little sister. Well, he was. Only it was the wrong
sister!
I looked into the bedroom, expecting Jerry to be fucking
Colleen, like he usually does at about that time of morning (Hey,
I like to watch too, you know!) and got a shock when I saw it
wasn't her, but their 7 year old sister Amanda.
Now this was definitely unexpected. I had been about to
remind my son that he had better be careful fucking Colleen,
because she had started having periods about two months ago; and
instead of the older girl, I find him laying the pipe in her
little sister. Damn, was that sexy!
It was obvious that this wasn't any rape, even though the
child was probably too young to climax properly, as she was
humping back at her big brother; mewling obscene things like,
"Fuck me," and, "Ooh, that feels good."
Maybe the little girl couldn't have orgasms yet, but she
seemed to be enjoying sex almost as much as her big brother was.
You could see the child's slit bulge each time her big brother
slid up inside her. His belly slapping wetly against her tiny
little belly, and the strained look on his face told me the older
boy wouldn't last much longer before decorating the inside of his
little sister's vagina with thick sticky ropes of incestuous
seed.
Well, at least SHE didn't have to worry about getting
pregnant, like her older sister did. Thinking of which, I looked
around for my son's usual "partner in crime." Colleen wasn't
there, but Marie was.
Why was I not surprised? I guess it only made sense that if
Jerry was fucking his 11 year old sister and his 7 year old
sister as well, that he would probably be fucking the one in the
middle too. Well, I wasn't SURE he had fucked Marie yet. The
little girl was standing there watching the action on the bed as
Jerry's thrusts into their little sister got more and more
emphatic. Her right hand was cupped between her legs, and a
slippery wet drool ran down her legs; but that COULD have just
been her own arousal at seeing her little sister get so royally
screwed. Whatever. If he hadn't already fucked the little girl,
I didn't think it would be long before Marie demanded "equal
treatment" with her little sister.
I climaxed myself, at the very thought; just as Jerry's
thrusts into the little 7-year-old became almost violent;
bringing "Oof"s and "Ow"s from Amanda. She didn't try to pull
away though. If anything, the little girl worked even harder
with her big brother to get him off.
I was just returning to rationality myself, as my climax
slowly ebbed, when Jerry stopped thrusting into Mandy, and just
pushed up inside her; shuddering. I knew my son was spraying my
little girl's womb with his potent sperm, and I almost climaxed
again at the very thought.

I guess it's a good thing that 7-year-old little girls
couldn't get pregnant, because my teenaged son had just pumped
enough baby-juice in his little sister's belly to impregnate a
whole raft of little girls like her.
"Are you done yet?" asked Marie, impatiently. "Is it my
turn now?"
Jerry rolled off his little sister, and just groaned; while
Amanda giggled.
I was almost ready to giggle myself, but figured I should
leave the kids alone, so they would feel less inhibited about
continuing. At least I didn't have to worry about either of THEM
getting pregnant, like their big sister could. . . Thinking of
which, where WAS Colleen? My question was answered, when I
finally arrived at the bathroom.
"Ooh, Daddy, it's so BIG!"
I didn't even have to look in the bathroom to figure out
what was going on, but I did anyway. As I figured, my eldest
daughter had her father's prick in her hot little hand, and she
seemed mesmerized by the swollen member. Dan's prick wasn't all
THAT big, at only a little over 6 and a half inches long; but I
guess compared to her big brother, it did look huge to the little
girl.
"Please Daddy?" She said. "I just want to feel it a little.
Jerry doesn't want to put his inside me any more, and I get so
itchy. . . Especially right now. Please Daddy?" she repeated.
Somehow Colleen managed to half-walk her father back to the
toilet, where he sat down with a thump. The pre-teen then kind
of waddled around her father and placed his pre-cum dribbling
penis up against her furry little snatch.
"I just want to feel it a little," she whined.
"But Colleen," Objected Dan; grabbing her around the waist,
to try and prevent her from coming any closer. The effect was
just the opposite from what he had intended. Placing the head of
her father's prick against her slippery little hole, my daughter
just sat down on him; driving his prick home in her tight little
belly. I could just imagine how hot and wet she was inside. It
was a wonder Dan didn't cum inside her immediately. I could see
him gritting his teeth to keep from spasming our daughter's womb
full of sperm. "Oh God, we mustn't," he groaned.
"Why not Daddy?" she asked. "Don't you like it? Jerry
always says it feels real good when he slides his thing up inside
me; only he won't do it any more."
"That's why," explained Dan; grabbing our daughter's hips
and holding her still. I knew that if he hadn't, Colleen's tight
little tunnel sliding on and off his prick would have had him
ejaculating inside her before he could stop himself. "What's
why?" asked Colleen; stopping her sliding up and down, at her
father's unspoken command. Still, I could tell the feel of her
hot little hole squeezing and milking on his prick was getting to
Dan anyway.
"Your brother stopped because he's afraid of getting you
pregnant," he explained.
"Pregnant?" said Colleen; puzzled for a moment. Then her
face cleared. "Oh," she said, "you mean I might have a baby. . .
I don't mind. Wouldn't you like to have another baby, Daddy?"

How my husband kept from blowing his seed all over the
inside of our little girl's belly when he heard that, I'll never
know. Maybe it was the fact that he noticed me looking in the
bathroom door at about that moment. Whatever.
"Your mother would have a fit, if she knew I was even
fucking you, let alone if I got you pregnant," he explained. "So
you'd better get off, before I do something we both regret." Dan
looked me straight in the eye, while he said this.
"I suppose," grumbled Colleen, "but it's not fair."
"What's not fair?" asked Dan, now that his daughter was just
sitting on him, not sliding up and down; tempting him to squirt
her cute little tummy full of incestuous baby-making cum.
"Marie and Mandy both get to feel Jerry inside them, while I
don't anymore, and I'm older," she pouted.
"Oh shit!" said Dan. "Your brother is fucking Amanda?" He
shut his eyes and groaned.
I knew right then it was too late for him to pull out, as I
saw a bubble of white liquid seeping out of our daughter's wide-
stretched cunny. I guess the stimulation of knowing our 7-year-
old daughter was getting fucked by her big brother had been too
much for my husband, Whether he had intended to pull out or not,
Dan had just ejaculated his seed in our little girl's womb, at
the very time her big brother had stopped fucking her because it
was getting to be too dangerous. "Oh shit," indeed. Still, it
wasn't completely his fault. There aren't many men who could
resist a nubile 11-year-old coming on to them like that. And I
could have spoken up at any time myself. But, like Dan, I had
been too caught up in the eroticism of the moment to even think
of objecting.
"Well," I said; coming into the room to join my husband and
daughter, "you two sure did it up brown, didn't you? When was
your last period?"
It took Colleen about 30 seconds to realize what I was
talking about, then come up with an answer. "I dunno. . . A
little over a week ago, I guess."
Oh shit, again. "Well, I guess it's too late to do anything
now," I decided. "Next month, when you have your next
period. . . IF you have your next period, we'll have to put you
on the pill. In the meantime, I guess if you're going to get
pregnant, you probably already are. So you might as well have
fun while you can."
"You mean it, Momma?" squealed Colleen. "I can fuck Daddy
all I want to? Thanks Momma. Thank you, thank you, thank you."
The little girl was almost bubbling over with gratitude. How
could I tell her that I was almost as turned on by the idea of
watching my husband impregnate his own daughter, as she was at
feeling her father's prick sliding in and out of her hot little
hole? I looked at my husband and shrugged.
Who would ever believe that my son's refusal to fuck his
little sister when she was fertile, would lead to her getting
pregnant by her own father?

Well, maybe Colleen wasn't pregnant yet, but I was almost
certain she would be before the month was up. With any luck,
things would be under better control, by the time Marie and
Amanda got old enough to make it dangerous. I shivered at the
thought. Of course, you never knew. . . 10-year-olds sometimes
became pregnant, and even kids as young as Mandy weren't
completely safe. Maybe we'd better start taking precautions
anyway. Once again I shivered at the memory of my 15-year-old
son pumping his seed into his 7-year-old little sister's flat
little belly. Then I imagined that same cute little tummy
swollen with her own brother's baby kicking and squirming inside
her. "'Heck with it," I decided. Marie and Amanda would just
have to take their chances, like their big sister was. If Jerry
didn't want to knock his little sisters up, I already had
evidence that their father could be talked into "taking care of
matters." I always had wanted a big family.
