Bart Simpson woke up again at six. He stayed up all night watching
"Late Night with McBain" and he didn't want to go to school. When he walked
downstairs, he noticed a bulge in his pants. He had had these before, but
never in the morning, only when he watched those shows on Fox. He arranged
his green pajamas so that they covered him adequately, and went
downstairs to fake to his mom.
When he got downstairs, he saw his father running around because
he was yet again late for work. He had just enough time to grab the last
donut *Damn* and run out the door. Lisa made her way down, in her ugly
blue pajamas. She was happy to be awake, because she always got good
grades, and going to school was something she looked forward too.
"Owww" Said Bart
"What's the matter honey?" Marge asked, her concern obvious.
"Ow, my ovaries" Bart groaned.
"Well, maybe you should stay home today sweetie" Marge replied
"No....must.....get....to....school" Bart intentionally gasped
"What, do you have another history test, bart?" Lisa provoked
"Lisa, give your sick brother a break. Bart, I order you to go to
bed and rest" Marge commanded.
Bart walked back up to his room *suckers*. As he made his way back
up, he noticed his penis was still erect. He decided to watch some tv, to
try to get his mind off of it. He changed around a few channels, watching
the spanish fly guy get beaten *hahaha* and some stupid soap operas. *
boring* When he switched to the soap opera, he noticed his penis began to
feel great. He was so young he didn't know what to do, so he just pulled
downhis pajama bottoms, to feel his penis. When he grabbed at his penis,
he began to feel incredible feelings like he had never had down there.
Suddenly, he heard his mother enter the room.
"Bart, can I get you some food for my sick little guy?" His mother
"Sure mom, I'd like some pancakes, some bacon, a couple toasts,
some juice.." Bart was cut off by Maggie crying in the next room.
"Oh, one minute, I have to get that. Would you come in and help me?"
"Fine, if it helps me get food quicker." Bart groaned.
Bart followed his mother into the room and helped as she changed
Maggie's diaper. She then took her right breast out of her green dress
and started feeding Maggie. As bart watched this he instantly became
aroused, and he began to stroke his penis like he had in his room, to make
it feel better. He was being as quiet as he could so he didn't disturb his
mom. Maggie greedily sucked at her mother's breast, and as she did Marge's
nipples began to become erect and sore. Maggie switched breasts after one
was emptied out, and continued the same treatment there, and when she was
switching a couple drops of the sweet white liquir dropped off her erect
nipple and onto the floor, which the dog drank instantly. After a couple of
minutes, much to his dismay bart climaxed. He panicked and ran to the
bathroom. *oh man, i wet my pants, I can't believe it* He snuck back to
his room and got some clean pajamas. On his way back, he noticed that his
pajamas were sticking to his crotch, which was chaffing it. He made his way
quicker on tiptoes so Marge wouldn't find him. He jumped into the shower,
and he tried to get things rationally in his mind. *Ok Bart, you just wet
your pants, you were sick, and mom was...oh no, not again* He thought as
hispenis grew again. *come on Bart focus*
"Honey, are you in the shower?" He heard his mother outside. *Shit*
"Umm... yeah mom, I just want to get some of the germs off of me"
"Ok, when your done tell me and I'll get your some breakfast."
Bart breathed a sigh of relief as his mother left. He looksed down
and saw his penis was still erect. *What the hell* he though as he began to
masturbate again, and this time he noticed that he wasn't peeing his pants,
it was something else. He knew he couldn't ask his mom, but Lisa was smart,
maybe she would know. He finished up his shower and he put on the clean
clothes. He walked out and grabbed his breakfast, then went in his room and
locked the door. He didn't want to be disturbed by his mother again,
especially not if he was experimenting and trying to figure out what it was
that was coming out of him when he was doing what he did.
Six Hours Later.....
Lisa came home with another A+ on her paper. Marge hugged her and
gave her attention, then Lisa went back to her toom to do her homework.
*Perfect* Bart thought as he walked into his sisters room.
"Umm... Lisa, I have to ask you something." Bart said coyishly
"What, do you have a girrrrl friend?" Lisa teased
"No, no, it's something much more different than that." Bart said
as he told Lisa the entire story. Lisa listened to it and took out a couple
of of her anatomy and biology books.
"Well, according to this, your penis becomes erect whenever you
have sexual stimulae." Lisa said scientifically
"Guh?" Bart replied dumbfounded
"Whenever you see something sexual, your penis grows." Lisa
"Can girls do that? I know they have a different body and all?"
"Yea, they can. It's like that movie dad has"
"What movie?" Bart said
"I found this once when we were gone during the weekend. Check it
Lisa puts the tape into the VCR, and sees two hot big breasted blond
women having steamy wet oral sex. After less than 30 seconds of this,
his penis is full grown again, and Lisa notices and is amazed by the size.
"Bart, your peepee is big again." Lisa says blushing
"Umm... it's called penis, right? Just call it that."
"Ok, your penis is erect again Bart"
"Yeah, I noticed. Have you ever seen a penis in real life before?"
"No I haven't" she said nervously. She knew what was to come.
"Would you like to?" Bart asked, he wanted relief and he couldn't do
that while his sister was like that. Lisa meanwhile, was trying to choose.
Sure, she knew incest was wrong from Reverand Lovejoy, but she still was a
scientist, seeking knowledge. And besides, she could always call her parents
out to get Bart off if he went too far, and she didn't want to regret not
having done something she could have.
"Ok Bart, but try anything funny" She said, and Bart pulled down his
Pajamas. His Penis sprang forth, and she was surprised to see the yellow
meat. She had only seen scientific pictures of penises in her books, and
they were nothing the size of an erect penis.
"Can I...touch it?" Lisa asked timidly
"Sure Lis, I thought you'd never ask." She began to stroke it, and
Bart shook at the feeling of another person going down there.
"Oh, that feels good Lisa, keep doing that." Bart began saying. Lisa
was grabbing him like the rope at gym class, and it was turning him on so
much. He was breathing heavy as suddenly the porn changed from two lesbians
to a short fat man and an older redheader woman. The woman was sucking on
the man's cock, deep throating it. "Lisa, can you do that?" Bart asked
innocently. He saw the man in the movie was enjoying it, and he didn't think
he'd have another opportunity anytime soon. Besides, Lisa seemed to be
almost having as much fun as he was.
"Ewww Bart, that's gross" Lisa said, although on second thought..
"Come on sis, it'll be like eating a hot dog, just don't bite. I
just showered today, so it's clean."
Lisa thought for a moment, then decided she would try it, and if she
didn't like it she could always stop or call mom. She moved her head down
to her brother's hairless crotch, and saw the size of the penis. She was
amazed at how big it was when she was right up and close to it. As she began
to put his penis in her mouth, She noticed it didn't taste bad, and let it
in a little more. This set off fireworks in Bart's brain, as the combination
of the porn movie and his sister's soft warm mouth continually sucking was
blowing his mind. Lisa continued for a couple more minutes, getting it a
little bit deeper in her mouth before Bart knew he was going to come. He
moaned to his sis "I'm gonna do it!" She didn't have a chance to wonder what
before he shot his entire load inside of her mouth. She was suddenly
surprised to have a mouthful of sweet and salty tasting semen. She tried
swallowing it, but alot of it spread off of her face and onto her chin,
covering her little face. This made Bart even hotter, to see his little
sister covered from her mouth down in his sperm. To her surprise, she
actually liked the taste of it. She kept it in her mouth a minute longer,
until she had to swallow it, then she took her fingers across her pajamas
and scooped up the remainging sperm. The room was dead quiet, because of the
fact Bart was ashamed and afraid that he had cum in his sister's mouth, he
didn't want Homer to kill him, and the fact Lisa was really liking it.
Bart was the first to break the silence.
"Um... Lis, I'm real sorry about that." Bart apologised
"It's ok Bart. I actually kinda liked it"
"Is there anyway I can make it up to you?" Bart tried to make a
deal,he loved the feeling and wanted some more. He was also afraid and he
wanted to insure himself against getting in trouble.
"I don't think so" Lisa said, and as she tried to think of
something, she didn't want to make Bart think she liked the taste of sperm,
but she did want to go further. Then she saw on the porno the girl climax
while under the man. An idea popped in her mind. "Bart, could you do what
they are doing on the tape?" Bart's eyes did an Ace Ventura double take,
and all he could do after his first blow job is nod sheepishly.
"Ok, so how do we do this?" Bart asked.
"Umm.. let's take our clothes off first I guess." Bart was already
half naked, and he had the chance to watch Lisa undress. He hadn't noticed
before, but his sister really had a beautiful body. Lisa first took off her
shirt and Bart began to notice her breasts, not only how small they were,
but also how nice her nipples looked. Then she took off her pants, and Bart
could admire her ass, he thought she had the cutest bum.
"Ok Bart, come over here, and put your penis into my vagina." Lisa
took control of the reins, she had to try to get Bart to believe this was
scientific, and that she knew what she was doing. Bart went to her, and
slowly set his penis at the tip of her wet mound. She looked over at him and
nodded, and he slowly began pushing his penis into her. He didn't want to
hurt her, and the feeling was so good that he didn't want to go to fast
and orgasm too quickly. After a couple of inches, he came upon an
intrusion. *What the hell?* He pulled out a little because he thought he
had gotten to the end of her vagina, but his penis wasn't even halfway in.
"It's my cherry bart, you're going to have to pop it." Lisa said.
"Won't it hurt?" bart asked, genuinely concerned.
"Yeah, but I can take the pain. For science." That was all Bart
needed, and in one fellow swoop he poped his sister's cherry. She cried out
in pain, and bit her lip. She nodded again after a couple minutes, and Bart
"Lisa...can I try something?" Bart asked.
"Sure....uhhh...Bart...." Lisa said inbetwen moans.
Bart lowered his head onto his sister's nipples, and began slowly
sucking on them like maggie had. "Don't worry Lis, I saw mom do this" he
said as Lisa was going crazy, she was having her vagina pumped and her
nipples sucked on greedily for the first time ever. Bart was confused, he
noticed that Lisa wasn't having any milk like her mom. He began to gently
bite on his sister's nipples, which made them get aroused, and was killing
Lisa. The feelings in Lisa began to swell, and she was having the most
intense sensations she'd ever had. Bart began pumping slowly at first, but
as her pussy began to become more lubricated from the constant action and
her own reaction to his sucking, he went quicker. She was moaningat his
"Ohh....yeah...do it bart...deeper, please, I beeeeeeeeeg you,
ohhh uhhh....thats good...oh my nipples...they're on fire....suck em oh Bart
come on, faster, deeper, please, oh" Lisa was close to an orgasm, and she
was aware of it. She moaned as Bart began to fuck her as fast as he can, his
penis going in and out a hundred miles an hour, and Lisa riding him like a
pony. Bart pulled his head back right as she was right about to climax,
and Bart pulled his penis out entirely then placed it back in all the way,
this sent her to ecstacy. She shook uncontrolably for minutes as she
experianced a mind blowing cataclysmic orgasm. Feeling this, Bart kept
pumping furiously, the combination of all the sex and his sister's orgasm
was making him ready to cum.
"Ohhhh, uhh.... Bart, that.....was....amazing, but wait...ohh,
uh, god it's so good, don't orgasm in me, I don't want to be pregnant.
Come on, I'll take your penis in my mouth again." Lisa said. Bart really
liked it, and he pulled out quickly. He didn't want to take any chances, and
lisa wanted to see if she could deep throat his entire cock, and as soon as
he was out, she did her best. The penis was well lubricated with her own
juice, and she was able to get it in halfway before it stopped, but then she
relaxed her jaw muscles to forced it down until it was three quarters
inside. Bart was going nuts, and he yelled
"I'm gonna orgasm!" Lisa knew what to do, she took his penis, and
held the head in her mouth, licking the tip of his penis. She knew he was
going to cum, and she wanted to taste it the second it came out. Unbeknownst
to her however, this was making Bart even hotter, he was on cloud nine
for minutes until he had finished his orgasm. Lisa got as much into her
mouth as she could, the rest she took and smeared over her nipples, which
were still on fire.They both dropped into a hot sweaty pile on her bed.
"Bart...huff...let's do that again sometime" Lisa huffed before
passing out. Lisa had to think today out before she went any further.
"Sure Lis....huff..., see ya ....later" Bart got out of his mouth
before he stumbled to get his clothes on. As he was getting his Pajamas on,
he noticed his sister was still playing with her vagina. He waited a minute
as he watch his sister get hot and wet again. His penis had gotten erect,
and he was pumping it furiously to cum again before she was done. She
looked up and saw Bart was still there masturbating, and she said "Shoot it
on my vagina" as Bart came a small load on her pussy, but she was burning so
much that just that was enough to send over the edge again.
