Simpsons Porn Story: a quiet night in

Bart was having a hard time understanding the mixed
feelings he was having lately about his 13-year-old
sister. Even though he was only two years older, he
had always been protective of her.

Sure, they argued and fought as typical kids always
did, but he still always made sure that she caught the
school bus, had her lunch and the other things that a
protective brother would do. And he knew that she
looked up to him as a “big brother” even though she
did sometimes act bratty.

Lisa was always “Little Miss Perfect”. Straight
A’s in school. Room always immaculate. Her clothes
always matched. She had big brown eyes
that could radiate whatever expression she was feeling.
They had a habit of making people want to do Lisas
bidding.

Until now, he had always thought of her as a little
kid. She had been in elementary school. She never
paid attention to boys. Her body had not yet started
the adolescent development… until now.

The first thing he noticed was the subtle way she
started appearing in a training bra. Second thing
was that she had started flirting with his friends.

He knew his thoughts
about his sister were wrong and that he should stop
thinking about her when he jacked off.

-=*=-

Something that had happened two years ago when Lisa
was 11 and he was 13 had made his sister one of his
favorite imaginary images when he jacked off. Bart
remembered sitting in the same chair that he was in
now, watching TV. two years earlier…

As Bart sat in the chair, the thought of jacking off
made him want to go to bed. His mom sat watching
Johnny Carson and drinking her third glass of wine
and he knew she would be asleep soon… usually right
there on the couch. “Night, Mom,” he said, getting
up to go upstairs.

“Goodnight, Bart,” his mom said and then added,
“make sure Lisa’s light is out on your way
upstairs.”

Bart didn’t remember the light until he had tossed his
Levi’s over the chair and started to climb in bed,
anxious to start stroking his cock. He knew that if
his mom noticed the light she would come upstairs to
turn it off and he didn’t want to risk her looking in
on him and maybe catching him beating off. He started
to grab his Levi’s but then shrugged and proceeded
without them. It would just take a second and it was
just across the hall. Dressed only in his jockey
shorts, he crossed the hall to his sister’s room as
he had done several times. She left the light on a
lot, especially if she thought there was a chance of
a nighttime storm.

He entered her room and turned off her light.

He was surprised that the room did not darken and
noticed that she had left the closet light on as well.
“Damn,” he uttered under his breath as he crossed the
room to turn it out. On his way to the closet he
stepped on a pair of his sister’s panties. When he
looked down and saw them, he looked next over to his
sister.

She slept in an oversized tee shirt and was on top of
the covers, on her stomach, her face buried in her
pillow. The thoughts that quickly ran through Bart’s
mind frightened him but the fear of getting caught was
quickly overcome by the excitement of getting away with
it. If Lisa had nothing on under that shirt and he
could lift it up without her waking, he could have a
great view of his sister’s butt. Wow. That would
make his upcoming masturbation session worth the wait.

He picked up the panties in his hand and closed and
locked her door on his way to the bed. The dim closet
light was perfect and just enough light for him to see
his sister clearly. He knew if she woke up that there
would be hell to pay, so he would have to be careful.
He quietly went over to his sister’s bed and stood
beside it for a few minutes watching her sleep. Her
breathing was deep and steady and he was sure she was
asleep. Lisa always had been a pretty sound
sleeper and hard to get up for school in the morning.

Bart’s heart raced so, that he could hear it as he
reached down and gently lifted the bottom of his
sister’s shirt into the air. There it was. With the
glow of the closet light bouncing off of it, the girls
round, smooth butt looked like a beautiful sculpture.

Bart was having trouble breathing quietly because he
was so excited and his heart was pounding wildly.
His cock reached full stiffness almost immediately.

After a few minutes of staring at his sister’s cute
petite little ass,
it was too much for him to bear. He took his free
hand and started massaging his cock through his jockey
shorts.

Slowly, he pulled Lisas shirt up with the bottom
of it just above her waste. Now with both hands free,
he held the front of his shorts down with one hand
while he stroked his cock with the other. This was the
best jack off he had ever had, with a girl’s bare ass
just a couple of feet from his erect cock.

Never taking his eyes off his sister’s bare ass, Bart
went into full stroke masturbation, forgetting the
short, slow, quiet strokes he had started with.
Suddenly, Lisa moved! Bart panicked and was in
front of her door in a split second. He would have
been out the door but he forgot he had locked it and
was fumbling with the lock in his panic. It took him
a minute to get back control of his shaking hands, and
in the interim he looked back at the bed.

Lisa had turned completely over! She was still
asleep, but this time she was on her back. It only
took him a moment to realize that he could have the
same view of her pussy that he had of her butt. In
the time that it took him to get over to the bed, his
panic was subsided.

Again, Bart lifted Lisas shirt and gasped quietly
at the sight of her tender mound. Bart lay the shirt
down just above her navel and again started his jerking
off, watching his sister’s bare pussy while he did it.
He was once again into a steady rhythm when Lisa
moved again. This time he didn’t panic and his only
reaction was to allow his undershorts to snap back up
over his swollen cock while he watched carefully to
make sure that she wasn’t going to wake up. He had no
clue what he would do if she did, but he was cautious,
nevertheless.

This time Lisas moving allowed both legs, which
had been raised slightly and bent at the knees, to
flat in opposite directions. The result gave Bart a
clear view of her slit, little hole and all.

Throwing caution to the wind, Bart pulled his shorts down below his hips and
stroked his stiff cock as he massaged his balls and
scrutinized his sister’s open pussy in earnest.

Bart didn’t realize until it was too late to do anything
about it that his cock was erupting, spewing gushes of
cum all over the bed and his sister below him. By the
time he returned to reality from the fantasy world of
his orgasm, a ribbon of pearly goo glistened, reflecting the closed light, as it crossed his sister’s bare,
flat stomach. Another wad had landed on the inside of
her thigh and flowed down her leg until it soaked into
the bedspread. Yet another had made its way to the
top of her mound where it quivered just below her soft
patch of hair and cascaded down her crack, crossing her
open hole and dripping the rest of the way down the
crack of her ass making a pool where her butt met the
bedspread.

It took Bart a few moments to get his senses and even
longer to catch his breath. Thinking rationally now,
he decided not to try to clean up his sister for fear
of waking her. He did lift her shirt, and, after one
long last look, covered her nakedness. “The shirt
would soak up his come,” he thought, “She wouldn’t even
notice it in the morning. Quietly, he exited her room
after turning the light off and went back to his room
where he beat off once more before falling asleep.

-=*=-

Bart felt guilty the next day about what he had done.
He had to keep convincing himself that Lisa really
was asleep and not faking it when he did what he did.
If she had been awake, well, she was as much to blame
as he was. But what if he had just scared her and
today she would tell their mom?

It seemed like an eternity before she finally bounced
down the stairs in her usual cheery mood. After she
had said good morning to their mom and him, he knew it
was okay. He also noticed that beneath her Bart she
still had on the same tee shirt. In the two years
since Lisa had never mentioned the incident. But
it wasn’t because she didn’t know that it happened,
I’m convinced of that.

-=*=-

When Bart had entered her room, she had been masturbating. Hearing the door start to open, she quickly
pulled her shirt over her bare bottom and rolled over
as if asleep. But there was nothing she could do about
her panties on the floor. When her brother lifted her
shirt up, Lisa pretended to be asleep. She dared
to peek out the tiny slits between her eyelids and
watched for a second as he masturbated. The sight got
her so turned on that she decided to give her brother
something to really jack off to, so she turned over.

When Bart jacked off some more, she decided to spread.
And after Bart left the room, she went back to masturbating, only this time she was gathering her brother’s
cum on her fingers as she rubbed her clit with one hand
and inserted a cum soaked finger with the other. It
was by far the best masturbating she had ever done and
she definitely wanted to know more about the white
sticky stuff that her brother had shot all over her.

Two Years Later

Bart knew his feelings for his sister were wrong, but
Lisa didn’t help matters much when she would flirt
with him every chance she got. He was sure it was
innocent, but she was always doing little things like
giving him a wink and a sexy smile as she closed the
bathroom door to take a shower. Or running around the
house in just pajamas tops when their folks weren’t
home. Like tonight. The folks weren’t due in until
after two in the morning.

That night both kids were home alone, their mom out
for the evening with friends. Bart was contemplating
setting the stage so that he could get a repeat performance with his sister, this time with her awake and
aware of it. Maybe if she saw him doing it, well,
maybe she’d let him do something to her, maybe…

“So, Fuck it!” Bart thought to himself. “I sleep in
jockeys and she sleeps in PJ tops. She’s wearing her
PJ’s around, I’ll wear my jockeys. And we’ll see what
happens.”

He wasn’t sure how far he would go with his sister
even if he got the chance, but he knew that her tight
little body excited him. Fuck her? Probably not.
She was still his little sister. Finger her twat, feel
her up or check her out? You bet!

“Nice underwear, Bart,” Lisa said, looking him
over up and down with a show of mock admiration as if
she were inspecting a male centerfold. “Wow!” She
thought. “Her brother in his underwear! It was gonna
be impossible for her to not let on that she was get-
ting turned on by this.”

“Like you’re overdressed, Lise!” Bart said.
Lisa plopped down in the overstuffed chair and
pulled her knees up to her chest, her arms around
them, half watching the video on MTV. Her position
allowed Bart a slight view of her panties below her
tee shirt.

And then he realized that he
was jacking off when his sister was in her room by
herself and at this rate he would never get to do
anything with her. They had to get past the bickering
stage if anything was to happen. It would have to be
up to him to break the impasse. He went to her room
and knocked.

“I’m trying to get some sleep!” was the reply.

He opened the door and entered the semi dark room.
A dim night light burned in the corner. “I’m sorry
Lisa,” he told his sister.

“Yeah, okay, but I still want to get some sleep,” she
responded.

“Okay, Ill join you.” Without waiting for a response, Bart hopped in bed under the covers.

“And what do you think you’re doing? Get outta my
Bed!”

There were several long minutes of silence. The mood
between them had definitely changed. But Lisa
still had her back to Bart and both pretended to be
resting, each not sexually interested in the other.
Lisa broke the silence. “What do you mean that
you like me as a girl?”

“Uh, well,” Bart stammered shortly, “like I noticed
that you are one of the cutest girls at school. And
even though we fight sometimes — I’ve known you all
my life, and stuff like that.”

Lisa turned toward her brother. “That’s nice.
Thank You. Um, you know, you probably won’t believe
this, but I like you as a boy, too.”

There was a short period of silence, once again broken
by Lisa. “Why are we in bed together, in our
underwear – or, I mean, in your underwear?” Lisa
giggled at her mistake.

Bart laughed back. “Well, if my being in my underwear
bothers you…” Without finishing his sentence he
reached down beneath the covers with both hands and
slipped his jockey shorts off over his hips.

He brought his legs up in the air to slip them off
completely and for a second Lisa caught a glimpse
of his cock. He held the underwear up in the air for
a few seconds and then ceremoniously let them fall to
the floor beside the bed.

“Shit, Bart, what are you doing?” Lisa felt as
if she had to protest. She couldn’t let her brother
know that her body was racked with a tingling sensation
just at the thought of having him naked next to her.
“Youre my brother!”

“I’m a boy. And youre a girl.”

“But, Bart, we’re related!”

Silence again. Longer this time. Lisa and Bart
looked at each other for a long time before Bart reached
out and placed a hand gently on his sister’s neck,
drawing her close to him. And then he kissed her,
gently on the lips. They looked at each other again –
sort of in amazement, and then, in passion, fell into
a lingering kiss. Their mouths opened and their
tongues entwined, the children kissed for at least five
minutes.

Kissing his sister was making Bart’s cock throb. Lisa’s whole body was tingling in passion as she made
out with her brother. Bart was afraid to make any
sexual moves because he didn’t want to frighten his
sister and make her stop. Lisa was enjoying the
kissing too much to do anything else. But soon, their
lips and tongues tired, the two stopped to rest.

Lisa looked down at the bulge underneath the cover
where Bart’s cock was actually raising the blanket. He
at first tried to cover it with his hand in embarrassment, but then decided that he wanted his sister to
see her effect on him. “I guess that means you like
what we’re doing,” she said with a nervous giggle.

“Guess you could say so,” Bart replied.

“Lemme see it?” asked Lisa.

Bart pulled the covers down over his cock and let them
lay at the foot of the bed. He had a much better view
of his sister’s pajama clad body now.

“Wow, what does that feel like?” she asked.

Bart took her hand and guided it to his swollen tool.
At first there was a little resistance when she realised that her brother was guiding her hand to his huge
swollen cock, but her curiosity and sexual arousal
took over. As she touched his prick, her fingers
caressed it. Bart showed her how to stroke up and down.

“Is this how boys do it?”

“Do what?” Bart asked, pretending ignorance.

“You know, jack off.”

“Here, lemme show you how I do it,” he said. Bart
moved her had to a resting point on his thigh and
grabbed his swollen cock with his right hand while he
massaged his balls with his left. Lisa watched
her brother masturbate. Bart was getting excited by
his sister’s intense interest. He continued to stroke
his cock and massage his balls for a few minutes. “It
works better if I have something to look at,” he said
with a sly smile.

“Like what?”

“Well, like I usually use playboy pictures and stuff
like that.”

“So go and get some.”

“I would rather look at you, um, naked.”

Lisa realized that they had gone to the point that
it probably didn’t make a lot of difference anymore
anyway. So what if Bart saw her naked. He had seen her
two years ago when he’d jacked off on her. She wanted
them share everything — all of their secrets.

She wanted him to see her play with herself, too. “You
mean you would rather watch your little sister naked
than some big busted model while you jerk yourself
off?”

“Yes. I would. So off with the clothes.” Bart had
stopped jerking himself off and was watching his
sister, waiting for her response.

Without a word, Lisa reached up underneath her
long tee shirt and pulled off her white cotton panties.
Then she pulled the shirt over her head.

“How’s that? Think you can cum as well to that as
some Playboy girl?”

“Better,” Bart said as he grabbed two of the four
pillows on the bed and propped them up against the
footboard. He turned around so that he and his sister
were facing each other from the head and foot of the
bed and with the pillows stacked behind him, he once
again begin to jack off. As Lisa watched, she
began to finger herself, her index finger making small
circles around her swollen little clit as the other
hand held her cunt lips apart. Bart had a perfect view
of her pink slit and soft mound covered only with a
very light spattering of soft brown hair.

Bart couldn’t believe that he was lying on his sister’s
bed, completely naked; jerking off in front of her
while she did the same in front of him. He watched
Lisa manipulate her little clit and she now had a
finger sliding in and out of her hole. As he stroked
his stiff cock, he felt a familiar stirring in his
balls. He stopped stroking so that he wouldn’t cum
right then and there because he wanted this to last
indefinitely.

“Why did you stop?” Lisa asked?

“If I don’t, I’ll squirt,” Bart replied.

“I wanna watch you do it.” With that Lisa moved
to a position right over her brother’s throbbing cock.
With one hand, she started gently stroking it and with
the other she gently massaged his balls as she had
seen him do himself, earlier. “Does it feel good,
Bart?” she asked.

The chain reaction had already started and Bart did not
have a chance to answer. His cock erupted sending
streams of hot jism into the air. One splattered on
Lisas cheek, another in her hair as she continued
to stroke her brother. Her hand was covered with the
pearly cum and Bart’s stomach was covered with splotches
of the white goo. She continued to jerk her brother
off until his cock began to loose it’s hardness. Then
she looked at her gooey hand and smiled. “What do you
do with this stuff when you do it by yourself?” she
asked her brother.

Bart was breathing hard just getting over the best
orgasm of his life. Seeing his sister there with cum
dripping down her cheek and her forehead made him want
to cum again. “I have a towel between the mattresses
on my bed,” he answered. Lisa examined her
brothers sperm on her hand and then reached down between her legs and spread the gooey cream all over her
mound.

“Guess after tonight we won’t have any secrets at all
from each other, Bart,” she said.

“Yeah, I guess not,” he replied.

Bart moved so that he was now lying on the bed in the
same direction as his sister. He reached over and
with the undershorts he had discarded earlier he wiped
his sister’s face dabbing off the ribbons of cum that
dripped down her cheek and forehead.

The phone by Lisas bed rang. Bart answered it.
It was their mom. They would be staying overnight and
wanted to make sure everything was okay. Bart smiled
when she asked him not to be fighting with his sister.
