Caramelos de Pasión

Chapter 1
--------------------------------
She knew how it had began, and why.

But she didn't cared about that, only caring that doing it had became her obsession, her relief. Her Nirvana on the dysfunctional comedy that she called life.

“Ah, h-harder, Bart!” She moaned, as she felt her brother fill her asshole to the brims with his young weenie. The feeling of being filled by him doing wonders to her stress levels, evaporating them at a rapid pace that other methods couldn't compete with.

The indecent sound of his pelvis hitting her ass cheeks inundated the three house, even as they tried to keep the sounds as low as possible, aware that their mother was mere meters from them, cooking the dinner.

Lisa looked back at him, his gaze completely focused on the point where they were one, his penis going up and down in a frenzy while he gasped, moaned and stuttered.

“Oh- L-Lees!” He moaned, raising his face to look at her, looking at her lips hungrily, which made her raise her hands and bring him down so she could also kiss him, a moan escaping her lips as he fucked her, their tongues dancing around each another in desperate wanton despite the awkward posision. “I love you, sis... sis... sis... sis.”

“Sis, Sis... earth to Lisa!?”

“Uh!?” She said, waking up from her daydream, looking around her for a few seconds, Another dream... “What do you want, Bart?!” She answered, completely and utterly frustrated with her brother at the moment. “I was having a nice dream...”

“Jeez, calm down. If you want to shoot someone, then shoot Mom. She send me...”

She sighed, knowing that the real Bart wasn't at fault here, “I'm sorry... what did she want?”

“It's Lunch time, Lees.”

She gasped, then looked to her window. Where had the morning go?

Sighing again, she said: “I'm coming... though, not like I wanted to...” The latter being barely muttered as she put her feet's on the floor.

“What was that, Lees?”

“Nothing, Bart... I'm... still sleepy. That's it.”

As usual, she put her happy face on the table, easily fooling the sharp gaze of her mother. She chatted, she smiled, and laughed with Homer's antics, but deep down she was irritatingly frustrated. When the lunch ended, she made her excuses and went to the bathroom, feeling slightly guilty that she had left her mother alone doing the dishes.

“You shouldn't feel it, though...” She muttered to herself, siting on the toilet and happily sighing in relief when she felt the pee come out, giving her at best a few valuable minutes to ponder while she did her business.

“This is all her fault, after all...” it was funny, really. She had thought that it would be Homer who would commit such an incredulous mistake. But, surprise, surprise, it had been her own mother who had committed the sin without even being aware of it.

Flushing the toilet after wiping herself clean, she went to wash her hands, her mind still pondering on the incident, as she had labeled it, when, to her annoyance the door was forcedly pounced upon.

“Jeez Lisa, hurry up! I need it!” Exclaimed Bart, who annoyingly didn't stop hitting the door, knowing pretty well how much that angered her.

“Hold your horses Bart!” She hasn't even half opened the door, when she felt his hands on her shoulders, which ignited her heart while making her clench her ass cheeks painfully. Would he? The fact that she found herself on the hallway, outside the bathroom told her that she had been tossed aside, the incredibly and disgustingly loud sounds coming behind her telling her that indeed, her brother situation could be classified as an emergency.

“Happens all the time he eats some veggies...” Which was why she had run to the bathroom like that, she rationalized, knowing how unpleasant it was to use the bathroom after him.

Even with her new fantasies, she had her limits.

She went downstairs, hoping to help her mom a little, despite how... annoyed she felt at her nowadays, only to stop on the stairs when she heard her...

They're doing it... again!

For almost a whole minute, she stood there, frozen on the spot, her cheeks violently red at the moans and giggles that emerged from the kitchen.

“Oh... Homer!” That seemed to wake her up as she went to her room, making care to not cause a ruckus that would reveal her presence to her randy parents.

“Oh God... Maggie's there, probably looking at them go...” She said, holding her breath a little while she passed the bathroom and went to her room. Her cheeks still flushing madly when she began to remember what had caused her to be so sexually aroused lately. “This is a nightmare...”

She closed the door, and made sure to push the lock, as she had been doing in the past days since that, happened. Her eyes betraying her and going toward the closet, where the stolen bag of candies still remained, hidden under her jazz LP albums, the only place were she knew nobody on the house would dare to search.

Sighing, she really, really tried to put her mind on other issues, but it was to no avail. Which made her feel as Pandora, unable to close the box that her own curiosity had opened without care of the well placed warnings.

She had just been curious. Did it really felt that good? It had to, as her mom had been acting like a bitch on heat since Homer bought them. Which was good, as the both of them had been more relaxed and downright happier.

Sadly, their happiness had come with a price.

And that was their children sanity, especially her brother, who had been repressing himself way too much for her tastes.

Only Maggie was blissfully unaware of the sexual tension on the house, just being a happy baby so far. But, not her, and certainly, not Bart. In the past, they both usually repressed such a thing, the two quite aware of how sexually active their parents were, Bart more than her, as he had the bad luck to constantly find them in the middle of some love making.

She heard the steps, and her heart quickened knowing that it was Bart after hearing the door of the bathroom close loudly behind him, probably unaware of what was currently happening down there. For a second, he stopped himself in front on her door, which nearly stopped her heart. But he continued his way toward his room a few seconds later, which filled her with quite a lot of relief, but also, a lot of disappointment.

They hasn't talked about what happened in days, and it was consuming her.

Her eyes immediately went to the closet, as her mind filled her with images of what had happened between them thanks to their parents own idiocy.

As always, she closed her eyes, her hand immediately moving toward her crotch... desperately searching for some release.

XxX

It had been a normal morning, filled with laziness and Itchy & Scratchy.

Re-runs that they hasn't seen in quite a lot of time, still funny, but not as they used to be. The two of them where doing their best to turn into coach potatoes, when to her consternation, Bart let the control fall under the sofa.

“Hey, Lees...”

“You lost it, you search it...” Maybe it had been thanks to the TV that her mind hasn't been as awake as it normally was, as she did her best to ignore the warnings that her senses were sending her a mile per second. Her ears completely focusing on ignoring her brothers mumbling while hearing Krusty demean his sidekick and himself, but mostly his sidekick with a low quality gag, his usual.

“Oh... hey look! candies!” That, on the other hand, had caught her attention immediately, as she herself was as much of an sugar addict as her brother. She looked at him, now fully focused on the black bag on his hands, his brown furrowed deeply as he looked at the big and quite red letters.

“Ca...ra...melos de pasión...” She cringed after hearing him butcher the quite obviously Spanish name, sighing annoyingly at him.

“Really, Bart... for someone who mutters and exclaims an Spanish catchphrase so much as you do, you can be quite illiterate about the language... which doesn't surprise me.” She took the bag from his hands, ignoring his glare as she watched it, a curious feeling on her mind while she studied it, when it finally made a click. “Hey, this is from Mom...” she finally clarified, looking at Bart incredulously.

“How do you know?”

“Oh, well... she and Homer were a little too busy trying to eat each another faces at the moment, but before I left, I saw her kick the bag by accident under the couch, I thought that she had noticed it... but she apparently didn't.” The truth was that, she had heard their moans and spied them a little before the sight of their naked bodies finally killed her insatiable curiosity.

“Are... are those the ones they had been eating lately before they... you know?”

That managed to get a reaction from her, her quite strong morals and repulsion at the images that had jumped to her mind imploring her to put the bag back under the coach, to ignore it, that she was now walking to a dangerous road that shouldn't even be stepped on.

“I... I think so.” She hasn't needed to see his face to know that he was probably blushing as much as her at the moment, all logic and decency quickly eroding on their minds incredibly fast by the second.

“I... I wonder if they're good?” She looked at him when she heard that, surprised at his words, which made him sputter slightly, then back off.

“I mean, I'm... just curious.”

Her morals crumbling due to her own curiosity, only made her nod lightly. Unable to even utter a meep of disapproval at the moment.

“Can... can I?” He coughed, then shyly looked at her, his eyes not daring to look at her own. “Can I have one?”

“W-we shouldn't...”

“J-just one, Lees... just, to know what's so good about them...”

She looked at him, then at the plastic bag. She had to admit that seeing her mother consume this sweets by the tons, had sparkled a slight worry about addiction. Which she had then tossed aside when the sounds usually began to come from their bedroom, her mind doing its best to block and ignore what usually happened, her usual.

“Bart... it's probably an aphrodisiac. We can't... we shouldn't...” Why was she even doubting herself on this? This was wrong, and immoral.

“C'mon Lees, I know that you're as curious as me about them... and... about it.”

And the sad truth about that was that he wasn't wrong, she was interested on it. What was so wonderful about it? Did it really feel that good? Was it better than kisses and cuddling? And with a loud squish, her curiosity won the fight, as it had expanded so much that it had turned her already weakened conscience into an flat red mass of flesh.

The fact that they were alone on the house also helped a lot to her resolve.

“OK... but... just one, and that's it!” She opened the bag, watching it carefully seeing that luckily, they seemed clean despite its last resting spot, which she knew pretty well was quite filthy... Hooray for the press seal.

“C'mon Lees!”

“Don't rush me!” She snapped at him, angry that he couldn't see how nervous she was at the moment... her cheeks completely rosy as she saw the shapes of the red candies. She giggled a little, then put her hand in, grasping four of them and bringing them out for them to see.

“Holly... dibs on the boobies!” Immediately called Bart, who's eyes were completely open at the sight, her eyes rolling as she saw him evade like the plague the penis shaped ones. She looked at the red pair of 'John Thomas'. Only to be interrupted by the sudden crunch that came from her brother, which captured her entire attention.

She just stood there, incredulous that he hasn't even waited up for her, but also, quite relieved to see him taste the unusual treat first.

“H-how... how does it taste like?”

“It's... weird, it's bittersweet at first, but later leaves a tingly and salty feeling on your tongue...”

With that information, she looked back at her own candies, and deeply thought about what to do, her zombified conscience apparently coming back from the death to nag her against it, only to be killed again by her own curiosity, this time with fire.

Curiously, her inquisitive self wasn't completely lost to her, her entire attention now focused on her munching brother.

“What do you feel?”

“Meh... nothing so far... don't know what's so especial about them...” He went for the bag, and without care emptied it all on his hand, busily choosing the booby shaped ones, and discarding on the bag the penises, then carelessly trowing the bag at her as he sat again on the sofa, munching on them without a care on the world. “Not the best candies on the world... but a candy, is a candy.”

With a sigh, she joined his side. Putting the penises on her mouth and ignoring his chuckle when she did so. As he had said, the confection was bittersweet, there was some liquid on the center, salty and effectively left an tingly sensation on her tongue, a not entirely unpleasant experience.

Shrugging, she imitated him and put herself beside him on the sofa, munching at a much ladylike pace... incredibly disappointed about the whole thing.

But then, she noticed it... it was a slight burn on her navel that had began after the first ten minutes, which made her move quite a lot on her seat, squirming lightly at the strange, but not entirely unfamiliar feeling.

Another thing that she had also noticed, was that the usual distance that existed between her and her brother had been breached long ago, both of them getting closer to the other, his hands carefully grasped firmly over his crotch.

Oh No...

She simply couldn't look away, her mind entranced by her brother not so subtle actions. She wasn't stupid, she knew what he was doing despite the clothes. Also, she was quite aware what laid under those short and undies...

“Lees... are you...?!” His voice broke up her spell, and she looked up at him, noticing that his eyes were now currently fixed at her own hands, who like his, were deliciously touching her crotch.

“I feel like I'm on fire... Bart!” She gasped when her hand brushed against her mound, her body being infused with a wave of delightful pleasure that seemed to abate the fire that attempted to consume her.

You're drugged, Lisa... snap out of it! Now before you regret it!

Deep down she knew that the way the both of them were looking at each another wasn't normal, they had never shown that kind of look toward the other, ever. Even when they bathed together, or saw each another stark naked, which was quite common as Bart used to have a nudist streak when he was nine.

Go to your room, relieve yourself away from here... stop it!

“Bart... can... c-can I see it?”

What are you doing!? NO!!!

Like a desperate beast, he pulled down his blue shorts and his undies, apparently more affected than her due to the amount of candies that he had already consumed. His weenie was pulsing and slightly red, its hood was down, and its head was now sporting a deep purple.

It looked painful, but strangely enticing.

“Lees...”

She looked up at him, he had a slightly mad but pleading expression on his face. With something else that she quickly identified. Fear... His brother was scared, not of her, but of what they had put themselves into...

“It burns Lisa...” He closed up his eyes, rubbing it slightly, closing his hand around it and pressing, but not pumping or jerking. It dawned on her at that moment that despite how devious and mortifying her brother could be sometimes, Bart was also really a quite sheltered boy in this particular area.

The fact that he didn't knew how to masturbate was the evidence of such a thing.

In truth, she didn't knew why such a discovery surprised her. It something defined her brother, was his ignorance... There where signs that she had refused to believe of said innocence, believing him to be the devil incarnated. How he had reacted when Shauna showed herself to him (something that she had nagged out of him), should have at least told her that Bart had stubbornly dismissed or repressed his sexual education, probably a product of his bad memories due to his bad encounters with Mom and Homer.

His gasp were deliciously entrancing, he looked quite sweet and vulnerable as he clumsily attempted to reach release to no avail.

She on the other hand...

“I can help...” She blurted out, probably close to faint due to what she had said, and the incredulous and surprised look on his face. “It's... not like that. I... haven't... I... might have used my laptop to see some porn...” Looking away, she tried to recompose herself, the way he had looked at her...

“So good little Lisa isn't as sweet and innocent as Mom likes to believe, uh?”

Again, she looked at him, and gasped. His eyes, the way he looked at her made her heart nearly stop, his smile, his gaze. She closed her eyes, and rubbed her legs together, gasping and moaning at how hot and bothered she felt.

His hand came upon hers, and she cringed lightly, but didn't push it away from her own.

“Show me...”

For the first time in a long time, she had her brothers penis on her hand. Her memory being bombarded with those showers where she had accidentally and not so accidentally touched it to satiate her curiosity.

His member was hot, and it was pulsing...

“Bart...” Closing her hand around it, she heard him hiss, then gasp when she began to slowly pump it up, then down.

“Oh my God, Lees...” The way he had submitted to her when she began to work him, how he moaned, hiccuped and gasped at each movement of her hand, completely at her mercy, had ignited something deep inside of her that she hasn't know she had or was capable of.

A hunger that she hasn't felt before... ever.

She jerked, pumped and moved the piece of meat with utmost care, fascinated how the head was covered and uncovered by the hood as she moved her hand dexterously over and over. Her fanny gushing so much that she truly believed that she had peed herself, and didn't care an iota of it.

Her mouth salivated, reminiscing scenes of women pleasing their lovers with their mouths and tongues, how would it taste like? Would it be salty, bittersweet? Slowly she began to lower herself, hungry to taste him... mere inches separating the two of them when, to their horror, they heard the unmistakable sound of their parents car, Mom's wagon in this case.

The spell completely broken by unfiltered terror moved both of them, Bart dressing incredibly fast while she turned off the TV and brought the bag with her as she rushed behind a terrified brother toward their bedrooms, or bathroom in Bart's case.

There she stood, behind the door, gasping loudly, her body still tingling about what had nearly happened, her tights and panties incredibly and utterly soaked at the moment, the fire unabashed, a really annoying sense settling on her guts. She had been so close, and worst of all, she hasn't done anything to quell her own needs.

Hearing the door, and the voices of her parents as they loudly called for them, brought her out of her fuss, reminding her that she still had a quite incriminating piece of evidence on her hand, so she rushed toward her closet, looking for the perfect spot to hide the incriminating bag...

XxX

A knock on her door brought her out of her reminiscing, and she found herself again wet, and incredibly and utterly frustrated with the entire world, but mostly, at her mother, who had called as she had, again, interrupted her masturbation attempt:

“Lisa, darling. Your father and I are going out to the Mall to... buy some groceries, yeah. Can I trust you to take care of Bart and Maggie?”

“Hey, this again? Did you already forgot what happened the last time you left her in charge?” Screamed Bart from his room, which made her grind her teeth's in frustration. He couldn't let that be, right?

“Sure Mom, I don't see why not. How long will it take?” Her mind was stirring with a lot of ideas at the moment, knowing pretty well that if she didn't find a way to satiate this need of hers, soon she would commit a quite Simpson mistake.

In simple words, a huge and quite messy one.

“Probably three hours, maybe four. We'll be back for supper... how about some Krusty Burgers and a Salad?”

“Make them two, and its a deal!” Bart screamed from his room, apparently now more interested on their conversation.

“One big Krusty, and an huge sized portion of fries only if you obey your sister, Mister!”

“Make no promises!”

“You heard him, Mom” -She added, as she silently rubbed her hands in a perfect rendition of Mr. Burns mannerism behind the door.- “That's the best you're going to get!”

She heard her mother groan, this time in frustration and a slight touch of resignation.

“Okay...”

“Sweet-o!”

“Bye Mom...” She stood there looking at the door, silent as she heard her mother depart the hallway after a few seconds, apparently preoccupied by how distant she had been lately.

But obviously too horny to care about it in the end...

“Yeah... the mall. She really thinks that I'm stupid?...” She muttered to herself, going toward the windows to see them part, or at least somewhat appease her mother as she effusively waved at them a goodbye, her trusty sax on her free hand, a quite simple and obvious lie of how she planned to pass her time.

One that her mother quickly swallowed up, as she smiled up at her.

Once they finally parted, Lisa smiled slightly, her hands shaking in excitement, but also a lot of fear.

It was time to have a quite serious conversation with her brother, who she knew was probably thinking the same thing as her at the moment.
Chapter 2
--------------------------------
She looked at the door, and felt her hand and legs tremble, her courage fleeing her body with each new minuted that she spent in front of his door, unable to reach him when she desperately wanted to.

Her breathing was slightly heavy, and her cheeks felt as if molten lava was flowing on her insides. But despite how much she truly wanted to kick that door open and force him to take her, she couldn't.

Not when her mind had screamed at her to stop for a fucking minute and think what she was about to do, and with who.

Bart might be a little slow compared to her, but if something had characterized him all these years, it was how devious and mean he could be when he wanted to. But more important of all, she knew that in this state, he would easily dictate the conditions and she would desperately agree, which wasn't entirely appealing to her. Thankfully, such a realization had managed to instill some common sense on her sexually driven body and stop her on her tracks, her hand half raised to knock on his door and call him out.

Hold on Lisa, you can't do this... at least, not like this.

Sadly, he opened the door, and she just stood there, caught looking at him stupidly.

“Erm, Hi...”

He looked at her, silent. As if judging... when to her surprise, he simply opened the door wide open and encouraged her to step inside.

She immediately accepted, even when her whole mind was screaming at her to not do so.

Looking around, she saw that his room was particularly clean, a testimony that their mother had been here, probably searching for the missing bag with the pretense of just cleaning his mess, which was her usual when she suspected him of something.

“I see that you have noticed Mom's actions...”

“Yeah... its hard not to.”

He walked toward the window, the curtains closed, he looked at them and fidgeted. Unable to look at her in the eye.

He's scared...

“Bart...”

“I'm not comfortable with this, Lees...” He walked toward the bed, and sat there, still not looking at her.

“Neither am I...” She confessed, knowing that at least that was the truth. But there, a little touch of his hand over hers was enough to ignite her flame. “But that didn't seemed to matter four days ago...” He gulped, and looked down... his hand now holding her own.

“We shouldn't be doing this...”

“I don't care...” She snapped up at him, scaring him a little, her patience all but lost. She pounced upon him, her eyes firmly glaring back at his. “Its all I can think about since, Bart!” She hugged him, putting her head on his shoulder, her whole body trembling as the tears finally appeared. “Its driving me insane!”

“I know...” She heard him say, “I can hear you when you touch yourself, Lisa...” She cringed, and wailed even louder, ashamed of what had become of her.

I've heard you call my name...

It wasn't necessary for him to say it, they already knew what was going on between them since that day. She gasped loudly when she felt his hand on her buttocks, her whole body trembling in a mix of excitement and fear that was driving her insane. His hands were unusually soft, as they clumsily groped and grabbed her covered ass.

She raised her head, and before he could do anything against it, she kissed him on the lips, softly at first, a moan escaping her throat at the contact, his lips were warm and soft.

It wasn't his first kiss, and neither hers, but it felt quite different from the others. His hands abandoned her buttocks and went toward her back, then her head, pushing her toward him as if he wanted them to become one with a single hug. He kissed back immediately, the both of them breathing heavily they tried to outdo the other. It was the most needy, passionate and intense kiss that she had ever felt in her young life.

Nelson, Milhouse, Nick, Lucas, all of them paled in comparison to him.

She moaned when she felt his tongue touch her lips, this was something that she hasn't ever done despite how much she wanted to. French kissing... the feeling of his tongue battling against hers was strange at first, but alluring, the taste, the feeling was unique. It made her mouth an special place to be explored at his entire whims.

At least, until she got tired of being submissive and fought back, taking him by surprise when she opened up her legs and sat upon his bulged crotch. Her fanny directly put over his crotch, only the fabric of their clothes preventing a penetration as she increased the contact, the new sensations making them gasp in surprise at how intense it was, both of them now completely and utterly hypnotized by the grinding.

He grasped her waist, and pushed down hard. Which managed to put his bulge against a quite sensitive spot on her fanny, which made her gasp, then give a long throaty moan. He pushed his bulge against her own, increasing the pace with each new second until with a grunt, he simply stopped. Her mind completely blank as she had reached an orgasm like no other.

She breathed hard, trying to recompose herself while on top of him, they had done it, they had finally crossed a line that they shouldn't have, and both had greatly enjoyed it. She felt good, mightily good she might add. Looking at him, she could see him gasp loudly, his eyes heavy.

Oh, no, you don't!

“Don't you dare to fall asleep, Bartholomew Jojo Simpson!” She demanding, grabbing his shirt and raising him up to her, waking him up in the act.

“I'm awake, I swear!”

She glared at him, before she nodded at him and said:

“Grab a towel, and come with me... we're taking a shower together... you're all sweaty and stink...”

“Hey, you don't smell like flowers, you know!”

“Do you want to see me naked or not?!”

“Shutting up!”

They ran to the bathroom, enjoying the feeling of freedom that being alone on the house gave them, the both of them struggling to take out their clothes as they pushed, laughed and squealed in the process. She just smiled at how naughty acting like this made her feel.

Once on the bathroom, she opened up the shower and went in... moaning lightly at the water that bathed her new body, enjoying the gaze of her brother on her anatomy.

“What are you looking at, come in!” She said, laughing at him when he moved like a bull on a china store and went in, slamming loudly against the tub.

“Ow...”

“Silly boy...” She knelled in front of him, making sure that he hasn't hurt himself badly in the process, her hands roaming his head for any injuries, shivering lightly when his hands went toward her exposed backside.

She just stood there, while he touched and grabbed her globes, it was silly, but despite how lame it looked, it felt exquisite, her whole skin producing goosebumps over, and over. Her eyes were closed, to intensify the experience, but she felt his head come closer to her chest, which then made her knees tremble in excitement as his lips brushed her left nipple.

“Ah... Bart!” She pushed his head against the piece of flesh, prompting him to increase his ministrations, it seemed that he wasn't as innocent as she initially thought he was. “W-where d-d-did you learn that?”

“Saw Homer doing it to Mom, she seemed to enjoy it.”

That made her pause, her eyes opened wide at that admission.

“Bart... you.”

“Our little experiment made me revive all those times I saw them do it. I even dreamed about it, thought, in my dreams the one that were doing it weren't them...” He blushed, and she smiled at him, hugging him immediately after she heard that.

“I'm so glad that you stopped repressing yourself Bart... that isn't heal-TY!” She gasped loudly when she felt his hands finally stop on her ass, his fingers inspecting her middle, dangerously close to her anus. She looked at him, surprised, and incredibly and utterly aroused.

“Its thanks to you, Lees.” There, she could heard it on his voice, that confidence that had made her classmates whimper in delight so long ago, it was so clear to her now.

Bart was a quite handsome boy. She now could openly admit it. His hands caressed her rosebud, a few hitched moans escaping her mouth as he slowly and carefully descended toward her fanny, his clumsy attempts to please her igniting her whole skin on fire.

Before she knew it, he had put her on her back on the tub, the water slowly pooling around her as she looked at him, her eyes wide and fixed on his own.

This was it...

He put himself over her, his member touching her mound lightly, the head throbbing lightly in desperate need. He humped at her, failing by a mile, but the touch igniting a wave of pleasure on her as he rubbed his penis on her lips, touching something that quite pleased her.

They just stood there, both of them gasping and moaning loudly as they pushed their waist at each another, trying to increase the contact as much as they could when it finally truly happened. In one firm thrust, he went partially inside.

Pain like they had ever felt before stopped them, both screeching loudly at the experience. They simply remained there, whimpering at the experience.

“It hurts Lisa...” He whined, and she glared at him for doing so, heavy tears on her eyes that were sadly hidden under the shower.

“Its supposed to hurt the first time, Bart...” She clarified, trying to calm herself down. “Ouch, don't move!”

“But you're about to crush me!”

“And you're breaking me in half, don't move!”

And there they remained, the moment gone due to their pain...

It took them half an hour for him to truly relax and go limp, which made it rather less painful for him to drag it out. She opened up her legs and looked at her fanny and whimpered, it was red and quite puffy.

“Mom is going to kill us... we're dead!” Said Bart, looking at her vagina, or more specifically, at the blood.

“She doesn't need to find out...”

“You're bleeding...”

“I know that I'm bleeding Bart, its supposed to do that...” She wasn't entirely sure, porn wasn't apparently the most informative media on the net as she had initially thought. “I need to use my laptop... we can get out of this easily, Bart...” She looked at him, and frowned. “Don't you dare to say it, don't even think about it!”

“Lees...”

“Don't fucking give up now, Bart!” She ranted, looking at him... her lips trembling. “Don't give up... please.” She closed her eyes, her hands trembling... “This has been the closer we have been to each another in ages, Bart... please...”

You're the only one that barely stand me nowadays.

“Okay,” She looked at him, and saw him being sincere, or at least pretending to be. It didn't mattered to her, this wasn't anymore about pleasure. It was for something else, something that she couldn't rightly say.

“Then come with me... let's try it again on my room.”

“We should bath ourselves first... I still smell and you're still stained red sis.”

She looked down and surely, her lips were a little scarlet red which would do. She nodded and to her surprise, the simple act of bathing together seemed to at least put him at ease, it also reignited their curiosity, and the desire.

Once clean and dry, they put the clothes on the bin, then left toward her room. A tiny smile on her lips, as she could see his eyes on her chubby behind. They went to her bed, and she quickly made use of her laptop, sitting cross-legged in front of him, searching and finding the information surprisingly easy.

“Here's the problem... you're too big, and I'm to small.” He seemed to swell up after hearing that, so she simply rolled up her eyes and continued. “Apparently, a lubricant might make the experience easier for the both of us.”

“Lubricant, like motor oil or Vaseline?”

“Close, but no Bart... well. I'm sure that Mom might have one... and apparently Vaseline is a bad idea.” She closed the laptop and put it aside, hopping down the bed and walking toward the door, “Come, let's see if she haves something to make things easier for us...”

“Wouldn't she notice it if we take some?”

“Probably, but if we're careful she might not.” It didn't take long to reach their parents door, once there, the both of them went and searched, thankfully, she was the first one to find the hidden surprise on her mother panties. “Holy...” She blushed madly at the size and shape of the thing in front of her.

“What did you find...”

“Don't come here, Bart... you, you don't want to see what's in here.” She evaded touching that thing, a little nauseated at where it could have been and in who. When she found to her surprise a bottle of lubricant, she gasped lightly then put it out, making sure to not touch the huge fake penis in the process. 

“What's so wrong...”

“Trust me, Bart. I will be repressing that memory.”

“But you told me...”

“This time the risk is quite worth it...” She walked toward him, and grabbed his hand, shaking the little lube bottle with her free one. “Now, do you want to have sex with me or not?” She giggled when she saw his penis react to her, quickly rising up to attention, she put some of the lube on her fingers, shivering lightly at how cold it was, before she rubbed it on her mound, cringing lightly at the sting of pain of their last attempt. She then grasped his penis and made sure to cover it thoroughly.

She put the bottle back where she found it after cleaning it meticulously, which was a quite hard job, as Bart hands roamed and caressed her body the whole time.

They tried to go to her room but couldn't, as his hand began to roam her body, she gasped loudly when she felt him push his member against her ass, his reticence completely and utterly forgotten.

It didn't surprise her at all when she found herself on her back on the hallway, kissing him passionately as he rubbed himself against her all over again. She felt him push himself against her, and she nearly stopped him, but unlike their last experience, this time she was prepared.

She hugged him tightly when she felt him go in, her whole vagina stinging painfully as he stretched her up as she had ever been stretched. It was painful, but not as much as it was before, in fact, slowly and steadily she could feel some pleasure as he finally speared her innards with his meat, then, with a last push, his hips touched her own, and there, Lisa knew they had finally culminated their sin.

They stood there, immobile for a few seconds, just enjoying the experience when he began to hump instinctively, which made her inside twist deliciously as she had ever felt before.

“Ah-ah!” She moaned, as he went up and down on her fanny with total abandon. The slap, slap, slap of their sin resounding loudly on the hallway. Their pace increasing with each new second, becoming frantic, needy, desperate. “O-Oh my Goa-ad, B-bart!” Now she finally understood why her mother was so obsessed with sex, and for a tiny instant she wondered how good of a lover must be her father to keep such a woman like her pleased and happy.

Then, it happened. One hard thrust against her hips that crushed her small mound against his pelvis put her mind down, erasing her thoughts at the seconds as pleasure beyond belief circumnavigated her entrails. She simply lost herself to what she was feeling, never believing that she could experiment something better than this.

It was there that Bart came, his member growing thicker and hotter inside of her, shooting over and over. It also caused her to climax, her inner walls clenching painfully over him, milking his meat for all it was worth it.

Before she knew it, everything went black.
Chapter 3
--------------------------------
It didn't take long to recover her senses, her whole body tingling after the most intense and fulfilling experience ever, had made her pass out.

“Oh, thank God you're awake... I nearly shat myself there when you passed out on me...” Said Bart, a noticeable tremble on his voice. She looked at him groggily, still feeling somewhat weak after her orgasm. “Are you okay there, what happened?”

“I think the orgasm was a little too much for me...”

“Jeez, you think so?” And there, he went back to his normal self... “Can you stand up on your own?” Or maybe not...

“I think so...” with some struggle, she managed to do so, her legs wobbly but strong enough to sustain her up, “How long was I out?”

“Not that much, two or five minutes max... so... is that going to be a recurring situation every time we do this?” She looked at him, surprised that he had been so bold to ask her that, her cheeks somewhat flushed despite what had just happened between them so far.

“I don't know... the women on the movies usually seem somewhat weak after the experience. So maybe we did something wrong... and really?”

“Sure, why not? I mean... it was good...”

“Doesn't mean that I'm going to end up whoring myself to you, Bart...” She narrowed her eyes at him, knowing deep down that if she didn't put her feet down on the issue, he'll be soon sharing her with Milhouse.

“Hey... I...”

“I know you, Bart...” He cringed, which was his usual when she used this specific tone of voice, “You're thinking that hey, she was the one to initiate it, she wants me.”

“You did...”

“I did... but that doesn't mean that I'm going to let you dictate our terms... for all I know, you're dying to tattle on Milhouse about what you just did...”

“I'm not that stupid man...”

“I'm no man, and yes, you're that stupid, you've betrayed my trust before, Bart... even broken your promises...” She glared at him when he attempted to answer back, which made him stop as she advanced on him, touching his naked chest with her finger to empathize the point, “How quick do we forget, isn't it?” Another cringe, which was what she truly wanted as he immediately frowned as memories assaulted his treacherous mind.

Putting her hand on her waist, she glared and him and began to point out:

“Listen here, brother. If you want to do it with me again, if you want to take your little sister as you just did. You need to accept my conditions, or the deals is off.”

“Why would I?”

“Because, let's be frank here, Bart. Who would Mom believe if I suddenly told her that you sexually assaulted me?” A gasp, and a quite hurt look on his eyes that nearly broke her at that moment, but she endured, knowing pretty well that it was for the best. It was a fickle gamble, she knew that, he knew that, as the evidence of their intercourse had gone down the sewer with the rest of the water and other fluids... though, she was aware of a damning spot on the floor that they would need to scrub on if they wanted to remain a secret.

“Why?” He was short, and concise.

“Because and I repeat and empathize it, Bart. I'm not going to become yours and Milhouse whore!” She glared at him, her eyes watering due to past memories, “You've betrayed me over and over, Bart. Several times have you valued Milhouse over your own sister! Have helped him court me above my own wishes...” Looking down, she closed her fists harshly, “Only once have you chosen me over him, and it was on a possible future...”

“Lees... I...”

“You would also whore me out to Nelson, or the rest of your bullies just to get out of a tight spot!”

“Hey, now that's...”

“Wouldn't you?!”

“Look at you, bringing up past sins as if you're bereft of guilt!” He shoot back, which caught her by surprise, which made her back off two steps as she feared that he could truly assault her at any second, which made him pause. “For Gods sake, Lisa... I'm not that stupid or heartless!”

“You can be...”

He looked at her, and the two of them simply stood there, truly and downright spend.

“What do you want?”

“No word to Milhouse, or anyone else...” She firmly stated, “If you tell, I'm telling Mom...”

“Even if that destroys the family?”

“I might not like it, Bart. But it is an risk that I'm willing to take to prevent you from using me as an bargaining chip with your friends or enemies...” He grunted, apparently angry of her constant use of that particular theme, but she had to be firm here or things could go turn down quite ugly in the future.

“What if our parents find out...”

“They wouldn't...”

“But what if...”

“They wouldn't Bart!” She repeated herself, her voice firm, “If we're careful, and only do it while there's no one at home... no one should even find out!” looking down, she had to admit that he had an point indeed, “And in the quite unlikely case that they do find out, I know how to deal with them.”

“How would you...”

“Please Bart... even you can see that...” And looking at him, she knew that he sadly did not see it, which was why it was so frustrating to interact with her brother, “This was their fault in the end, Bart! It was their own quite irresponsible behavior which lead us to this...” —She waved her hand over her naked body, then his own to make a point— “This is a consequence of a classical Simpson mistake...”

Seeing that he was quite incredulous, she quickly added:

“Would you have truly see me in such a sexual way without that bag of candies?”

“I...”

“Don't lie, Bart. Both of us know that the only answer to that is a no...” Sighing she massaged the bridge of her nose, “While we have seen each another naked, and there had been some instances that might be considered or taken as sexual, we usually just saw each another as brother and sister. That bag of aphrodisiacs changed everything between us...”

He nodded, apparently now understanding what she was talking about. Seeing that he had somewhat relaxed, she added:

“This also would need to stop as soon as I reach my first period,” He opened his mouth, about to protest when she hastily added, “Bart, while having sex is fun and quite pleasurable... that's how babies are made... and unless you suddenly want to find yourself the father of my children, that's the end of the line for us... even if we somewhat found preservatives and pills to keep doing it, the risk is still there, pregnancy could still happen...” Seeing him suddenly deflate at hearing that, she also said. “Don't worry, there's a lot of time before I reach that stage... probably two or four years if we're lucky, one year if we're unlucky... and there's still a lot of changes to do it.”

Her eyes quickly went to his member, that had stiffened and raised up to attention after she told him that, which had also ignited an small spark on her fanny again.

“Can we do it again?”

Biting her lip, she nodded but then looked at the spot on the floor and said:

“We can... but we need to clean that, or someone —most probably Mom—, is going to find out...”

He looked at the spot and cringed, seeing that yes, it was quite revealing as her bum shape had been slightly imprinted on the surface.

“We have to be careful, Bart. Our asses depend on that...” She clarified, being quite insistent on it, thinking deeply about what to do. “The couch is too dangerous due to the front window, someone is always watching at our house, and even if we close the drapes, there are some spots were you can see inside with ease...” He nodded when he heard that, as the both of them were quite aware of such spots, as they had somewhat used them for different reasons in the past.

“The kitchen is a good spot... close to the stairs and the garage...” —a pause, then an mutual smile— “The garage!”

They ran toward it, nearly forgetting to clean the floor in the process, which she ended up doing, as Bart fixed things down there to make the experience the most comfortable possible.

In the end, it hasn't taken them that much to finish, and she found that indeed Bart had made something quite passable to lay in, as she saw the discarded and still unused back seat for a mini-van that Homer had idiotically bought thinking that it would fit on his car. It was comfy, and still covered by its plastic, which she saw was hastily cleaned of dust.

“We'll need a bath after this...” she muttered, inspecting the whole seat, and finding it quite amusing that she would have sex on a car seat at her age, with her brother, and outside a car.

“We'll need it anyway, we kind of stank...” Offered Bart while looking at her on the seat, which he promptly patted, inviting her to sit at his side, which she soon did so. Sadly, unlike their desperate attempts a while ago, this time the two of them simply stood there, uncomfortably looking at any point but themselves, which she had to admit was downright boring.

“Wait here...” She added, rushing toward the house to look for something that she knew would spice things up for them, once she grabbed it, she ran back down to find Bart on the kitchen looking at the refrigerator, “Stop it Bart, we need to move it quick, or we'll lose our chance!”

He looked at her laptop and smiled, apparently getting what she wanted to do with it.

“Sweet...”

Once they sat, she opened up her laptop and quickly began to tap and move the cursor with some dexterity, deactivating the parenting control with ease. Letting her computer free to roam the net at her whims...

“Whoa... what's that?”

“Its called Scarlet-tube... its a site that specializes in pornography...”

“Really?!”

“Really... though I have to admit that I'm surprised that you hasn't heard of it before...”

“You really think I would be asking if I knew?”

Shrugging, she simply bit her tongue and decided that fucking was more important to her at the minute, than mocking and fighting up with her brother. Clicking on a particular popular video, she simply began to see what was happening there with a now quite randy brother, who attempted to hide his surprise in vain.

“Whoa... what's? Ew!...” He exclaimed, and she looked at him slightly amused at his reaction when he saw the woman go down on the man, “That's... disgusting!”

“I don't recall you stopping me...” She added, forcing him to remember the incident, which made him blush atomic red at her, his eyes telling a whole set of quite obvious questions that hasn't needed to be heard to require an answer.

“I've... —cough,— I've seen people do that over and over on this videos, there are even a whole category and section on this page dedicated to that...” She smiled a little at his incredulous face, he was quite cute when he looked at her which such incredulity and innocence, eagerly awaiting for her next answer, “I was... curious, about its taste I mean. It had to taste good to make so many people practice it, and...”

A load moan, followed by the couple soon engaging on mutual oral pleasure, quickly and easily put an image on their minds of what to do next...

“I'll... don't mind... I mean...” She looked at his member, it was red and quite hard, throbbing lightly under her scrutiny. “If... you want to... yeah?” She looked at the laptop, and smiled slightly when she saw him nod. Which had made her quickly close the computer and watch him stand, as that gave her the chance to laid down on the quite large and comfortable back seat. Her legs opened, which made her shiver lightly as she felt her mound burn as he stared at her.

“Don't just stare...” She added, which woke him up from his spell, as he nodded and moved toward her, carefully kneeling, one leg beside each side of her head, and with some reluctant trembling, he finally laid himself upon her, his member crushed against her mouth that she stupidly hasn't opened yet, her nostrils getting the full aroma of pee and sweat, alongside something new.

It didn't take long for her to open it despite her fear, and let it in. Finding that it was salty, the point putting a somewhat sticky substance on her mouth that wasn't as delicious as she thought it would be, but it wasn't disgusting, and she even dared to admit that it was quite tasty.

She moved her tongue around it, playing with the front skin as she sucked as much as she could, trying to emulate what she had seen with poor results, but the way he kept pushing his member at her told another story, that despite her amateurish technique, he was finding the experience quite pleasurable, which emboldened her actions as she began to bob her head up and down.

His moans and the way his body felt pressed up against her, gave her an feeling of power that she hasn't ever felt before over her brother. He was at her mercy, prey of the pleasures that she inflicted upon him with each movement of her mouth, and somewhat understood the appealing of this activity.

Then she felt him shift and force her legs open, as she had closed them a while ago, and before she could even mumble an attempt of an moan or protest, he went in... his young tongue lapping at her most intimate of places with a fervor that he barely showed for anything else.

Like hers, he seemed to have found an liking to the taste, because his scrutiny and intensity increased with each new lap. His tongue growing bolder by the second as he focused it around her entrance, his chin constricting her young mound with each movement that he made, which had made her seen stars all over again.

They just stood there, sucking and lapping at each another as much as they wanted to, grunting, moaning and spasming as they attacked each another, until, with a grunt, she wailed, his Willie firmly held on her mouth as she felt her inner walls spasm and clench around his tongue, a long throaty moan escaping her lips as she pushed her head up, forcing his member down her throat for a few precious seconds, which seemed to be what he had just needed to finally cum a second time.

She pushed him off her, her face getting hit with an small amount of his sperm as she coughed desperately the substance out of her, then they simply stood there... wheezing loudly as her body was still spasming after such an intense experience, her eyes never leaving the spit covered piece of meat that just a few seconds ago had been deep inside of her mouth... an itch on her rose bud telling her that they had one last thing to explore before they reached an end to this, once and for all for the day.

“Bart... do you think we can try another thing?” She looked at him, and saw him smile at her, his member moving a little as he inspected it.

“I think so... what do you want to try?”

“I... want you to stick it on my ass...” She mumbled, feeling ashamed of asking him that... fearing what he would say of such a thing.

“You want me to what?”

“I cleaned it... as much as I could...”

“Is... is that possible?”

“Yes... it is. But be careful Bart... I don't want it to hurt...” She told him, knowing that not mattering what they did, it would hurt.

But she needed it, she truly and really needed him to do that to her.

“Okay... just...” He raised himself, and she hastily rolled up, exposing her ass to him, he looked at her, doubting for a second before he nodded and went to her, once again putting himself over her, his hands trying to open up her cheeks, which she quickly knew wouldn't work, so she put her hands at work and opened up for him to see.

“Wow sis... you're... leaking!” He said, smiling slightly at her flushed face that was now carefully looking at him, as he slowly went down on her, his hands caressing her vulva, touching her over and over when, to her surprise, she felt a finger go in...

“AH!” She cried, delighted at how good that felt, her hips trembling as he moved his finger inside, her inner walls clenching the intruding digit as much as they could at the moment. “B-Bart!” She moaned his name, and this seemed to snap him up of his staring, his face growing enthusiastic as he suddenly put himself beside her and simply put his penis in.

She groaned, huffed and even screeched a little as she felt him inside of her fanny in this particular position, her mind nearly going blank once again, as pleasure beyond belief assaulted her with each new thrust of his waist against hers, his pumping becoming harsh and needy.

“B-Bart! My... ah... oh God... ah! My Ass, p-please!”

He stopped himself, which gave her an moment of respite, a long soft moan escaping her lips as he left her vulva, his hands roughly pushing her cheeks apart as he searched for his new objective. She wanted to stop him, knowing that he was too hyped up to take her asshole gently, but something deep down on her told her not to, to take it, and enjoy it.

A gasp escaped her mouth when she felt the point of his member at her entrance, then with an quite too harsh thrust, he went in... An scream escaping her mouth as pain suddenly inundated her body, pain that somehow was quite mixed with pleasure as he pumped savagely against her, grunting like an animal as he penetrated her anal cavity.

She had had to bit hard on the seat to prevent another scream, as the mix of pain and pleasure battled on her asshole, the pleasure increasing with each new thrust of his juvenile meat.

Soon she was moaning, maybe too loudly to be considered safe, but for once, she didn't cared. And neither did he, too focused on the mutual pleasure that they were having to truly care about being discovered doing something that they shouldn't.

The seat creaked with their combined movements, scratching the concrete of the garage floor as she pushed herself against him, and him against her. Her moans resounding loudly on the place as the sinful sound of their mating reached its peak, then, with a hard last thrust, they came.

Thankfully, unlike their first time, she hasn't lost consciousness after the orgasm, but regardless of that victory, she felt utterly and totally spent, her abused ring felt expanded beyond belief at the moment, the weight of her brother above her, the sound of his labored breath beside her ear...

“I love you so much...” She whispered, not truly knowing what she was doing... or why.

“I love you too...”

She smiled, feeling the most happy that she had felt in a long, long time as her body lost its strength... a heavy cloud numbing her senses, she was tired... Quite too tired, but she endured and with an herculean attempt, the both of them simply walked upstairs and bathed themselves, this time mostly focused on some caresses and kisses, but nothing beyond as they were simply too spent.

They went to their bedrooms, and she quickly put an pair of clean undies and her night gown... pondering on what to do, when to her surprise he cleared his throat on her door, a pillow under his arm.

“If we do that...”

“I don't care...”

She smiled, enjoying how this experience had made her closer to her brother like no other adventure had done before, so she simply nodded and went to her bed, followed closely by him. Both of them snuggled up to each another, his belly tightly pressed against her back... the distant sound of thunder on her ears.

“Oh, look at that... isn't that cute?”

“Shush Homer, don't wake them up... where's my camera? I need to take a shot of this!” 

She opened her eyes lightly, and saw her mother silently close the door, smiling at the fact that they hasn't suspected a thing at the moment.

“Can we do it again?” Asked Bart, whispering at her ear and sending shivers down her spine as he pressed his hard on against her ass.

“Let's wait until they fall asleep...”
Fin.
