"Haaahhh... Haaahhh... Haaaahhh... Haaaahhhh..." Came the almost-matched pair of panting from the rodent sisters on the gymnasium's floor.

While they may have accomplished singers & won some fair popularity because of their vocal talents, Jeanette & Eleanor were hardly the pinnacle of fitness. And they struggled with such intense exercise like this on a weekly basis.

The former preferred to work on her brain, knowing that it would be much more important to her later in life. The bookworm chipmunk usually had her nose buried in the pages, so physical activity was pretty rare for her.

The latter was arguably worse; the only thing she seemed to work on was her gut. If she could find something edible, and ideally sweet, she wouldn't hestitate to scarf it down. It was a wonder the pink-clad chipette didn't have a weight problem, but she was at least active enough that she never gained any pounds.

However, despite their lack of cardio, the girls were still forced to do this every week for school, just as the rest of the class did. And as always, they were left a sweating, heaving mess by the end. Whether it was laps, rope-climbing or dodgeball, the two of them just couldn't keep up.

They were always grateful when the bell rang & it meant class was over. And they were even more appreciative that it was the last period on Friday, meaning they would have a whole weekend to recover from it.

Jeanette had her glasses fogged over from her heavy panting, as she tried to push herself up.

"I... I think I'm done...!" She wheezed, just barely finding the strength to get on her hands & knees

Eleanor didn't answer at first, too out of breath to respond. Her pudgy belly was moving up and down like a buoy in the water as she breathed heavily.

Both of which were prime material for the third of the trio to come in and remark on.

"I see you two are improving(!)" Brittany stated sarcastically, standing triumphantly over her sisters with her hands on her hips.

She wasn't an athlete herself, but she was in much better shape than the nerd & lardass were. And whenever she had the chance to brag, it never went to waste.

"How long before you collapsed this time? 1/3 of the room? Or was it 1/4?"

The two other chipmunks rolled their eyes, as they were used to the pink one's arrogance.

"Brit... Brittany..." Jeanette moaned, finally starting to make it up to her feet.

Eleanor was still down, trying to get her breath back first. Though if she could've put her fingers in her ears, she would've. It would've been the best use of what little energy she had left.

"Ooooh, standing up now(!) We're really pushing the limits this time, Jeanette(!)" The prima donna remarked with a giggle, looking down at her sister. "That's it, give it all you got! That's a good girl(!)"

The blue-clad chipette groaned in frustration, not even wanting to bother responding to her. She just wanted to get her energy back and be ready to shower & head home, like everyone else.

"Are you... Okay, Eleanor?" She asked, looking down at their other sibling on the floor.

"I'll... Be fine..." The chunky chipmunk finally responded, slowly starting to push herself up. "Just... Need a... Minute..."

"Yeah, you take your time, El." Brittany told her, rolling her eyes as she turned around & headed for the school showers. "Don't rush on my account."

Seeing her walk off, the horizontally-gifted girl stuck her tongue out at the show-off she had to put up with. She hated how arrogant the other chipette could be at times, and would've loved to have knocked her down a few pegs.

Though as her body continued to protest getting off the ground, it didn't look like that was going to happen anytime soon.

Jeanette was in the same boat; as much as she would've loved to teach Brittany a lesson, she didn't think she could bring herself to do it.

Not only was her sister in better shape than her, but she had more wit than she did, despite her own higher IQ.

So as it was, all they could do was try to ignore it and hope she got her just desserts soon enough.

In the meantime, they had each other. And that was good enough for them.

Though one of them, in particular.

For the longest time, Jeanette was sure that there was something wrong with her. Some kind of depraved sickness inside her that needed some sort of treatment.

The way she looked at her sister, and thought about her, certainly pointed to that.

Ever since Eleanor was born, the bespectacled chipette was fascinated with her. In a way that a sister normally wouldn't, of rather shouldn't, be.

But she couldn't help it. That chubby frame, those cute piggytails, the way her skirt often flapped up on the back to let anyone have a peek of her undies, even the way she farted in her sleep, it all made her seem so attractive to the nerdy sister.

And man, did those farts stink.

It also didn't help her heart slow down by the way she was glistening in sweat right now, giving her an even cuter look as the setting sun shone off her.

Jeanette felt her heart race, being alone with her right now. Though not as much as it was going to do in just a few minutes, when they would be naked together in the showers. It was one of the best parts of being at school, and was nearly worth the hour of pain from the physically torture she was forced to endure. Seeing the love of her life naked & wet, soaking down that pudgy body was a pleasure that even heaven couldn't provide.

But she was determined to take this secret with her to the grave, no matter how tempting it was.

The two sisters were close, and the last thing she wanted to do was ruin that, even if they did share a bedroom.

Instead, she just watched as her chubby sister got back up to her feet as well, checking to see if she would need to help her keep her balance.

"Are you okay?" She asked as nonchalantly as she could.

"I'll... Be fine..." Eleanor answered, managing to keep her balance, despite how the world was still spinning around her.

"You wanna... Hit the showers?" Jeanette asked, trying not to get too excited by her own question.

"You... Go ahead." The portly chipette answered her, waving her hand in the direction of the gym's locker room. "I think I'm just... Gonna head straight back..."

That was disappointing, but Jeanette didn't argue. The last thing her sis needed was more bossing around; they both got enough of that from Brittany.

"Okay, then." She said simply, starting to walk toward the showers. "I'll see you back at the house."

"See you there." Eleanor replied, managing a slight smile, as she got herself moving.

At the very least, Brittany was treated to seeing those fat hips sway as she walked off. The amount of sweat she built up made her buttocks fairly visible on her tracksuit.

It wasn't often that someone said they were envious of a pair of pants, but Jeanette could gladly say she was part of that minority.

She couldn't wait to get her hands on those things.

As Eleanor walked out, the nerdy chipette started heading into the showers, eitb her mind still on her sister's body. She felt her face heat up and her privates twitch just thinking about the things she would like to do to with that chunky-

"Oh, gimme a break!"

That snapped her out of her lusty thoughts; hearing her sister's exclamation.

"What's the matter?" Jeanette asked, quickly moving toward her voice, seeing her butt-naked sibling standing under the showers with an unhappy look on her face.

"There's no water!" Came the impatient-sounding reply of the self-proclaimed star of the famous trio.

Indeed, the showers weren't running when she came in, leaving the room bone dry.

"That's weird." The intellectual sister commented, as she looked at the showers.

Sure enough, not a drop of water was coming out. Not even the slightest drip.

"This is lame!" The nude rodent remarked, crossing her arms over her chest. "Now I'm gonna stink like El's armpits until we get back!"

The rude comment irritated the intelligent girl a bit, but she didn't have the nerve to retaliate or defend their other sister's honor.

Partly because she was still too timid, but also because the thought of those musky underarms was driving her wild.

She shook her head, trying to clear the thought away.

"We could always use the ones at home." She suggested, as her sister stepped out from under the showers.

"Well, duh!" Brittany snapped, giving the girl a glare, who was quick to avoid eye contact. "But I'm using it first, got it?"

Not wanting to argue, Jeanette just nodded and picked up her bag, ready to head back to-

"Whoa!"

The scream, accompanied by the sound of something slippery squelching across the floor, prompted the young genius to turn around and see the source of the commotion.

Coupled with the other noises came a THUD, just as the leader of the singing rodents fell hard onto the tiled floor.

"Owww!"

Jeanette's eyes widened, seeing the nude chipette having slipped & fell.

"Brittany, are you okay?" She asked, rushing to her aid.

"What's it look like, brainiac?" Her sister spidery replied, looking ticked off at the question.

And she wasn'trhe only one.

Jeanette was getting seriously fed-up with her sister's snarky attitude as of late. It wasn't her fault that she wasn't looking where she was going, and now she was having a go at her, just for checking her well-being.

She was starting to wonder if her other sister had the right idea of going home, without even showering. At least he didn't have to put up with Brittany for about an hour or so.

"Well, don't just stand there." The lead chipette complained, reaching up her arm. "Help me up."

Jeanette rolled her eyes, before putting her bag back down and kneeling down to do so.

But as she did, something started to resonate within her.

The way her sister was on the ground like this, helpless & unsuspecting, she didn't exactly boast a figure of authority right now.

Plus, she just yelled at her for doing nothing wrong, and still had the nerve to boss her around, like usual.

This may have been the only chance she would get.

Brittany saw the girl hesitate, wondering why she wasn't helping her yet.

But just as the next commanding insult was about to leave her lips, she was met with a response she would've never expected from her nerdy sibling.

"No." Jeanette sternly said, standing up straight with her arms crossed.

Her sudden change in attitude, coupled with the unexpected refusal, was enough to make the lead chipette's eyes widen.

"Excuse me?" She asked in a tone that mixed her surprise with her disapproval.

But in a rare instance of their lives, Jeanette didn't back down from her stand. Instead, she doubled down on it, with an equally unexpected action to match her response.

The bookworm turned around and bent herself down a little, jutting her posterior out towards her floor-bound sibling.

And before Brittany could make a remark about whatever her sis was up to, she was about to be met with a sight she could've happily died without seeing.

Her sister's thumbs slid down into the waistband of her gym shorts, and with a tug, she was greeted to the unholy sight of a full moon.

The sweat-coated, musky ass in front of her was enough to make Brittany want to gag, but she wouldn't have the chance; Jeanette beat her to it.

"I've got a much better idea." She declared, taking a shuffle backwards and pressing her rear right up to her sibling's face. "You can kiss my butt instead!"

The demand wasn't going to be met with any refusal, as Jeanette saw to with how firmly she pressed herself against her.

Brittany's face was smushed in between the sweaty buttcheeks of her sister, her nostrils being filled with a strong musk that was burning her nostrils.

But as she tried to turn her head and push her sister off, the latter wasn't having it.

"No, you don't!" Jeanette snapped, grabbing her downed sister's wrists with her hands & holding her firmly in place. "You're staying down there until you learn some manners!"

Brittany never knew her smart-alec sister had this dominant side to her, but she wished it stayed dormant.

Try as she may, she just couldn't break free of her grasp, and the more she tried to wriggle her head out of the nasty crevasse, the more she coated herself with the unhygenic fluids that came from her sister's butt.

"Get off me!" The stuck-down girl shouted, as the sweat from her face was starting to sting her eyes.

"Nope!" The dominant sister replied, giving her ass a shake to drive her point home. "You treat me like grime, now you get to feel what it's like!"

As if things couldn't get any worse, the next words out of her mouth would certainly seal the deal.

"And once I'm done, everyone will see how low you really are!"

Before Brittany could ask, she found herself quiet for just long enough to hear the sound of the camera app on her sister's phone snapping some shots of their lewd activities.

"You're not sending those anywhere!" She yelled, as she struggled to free her head.

"Oh, yes I am." The other girl replied, as her fingers quickly typed up a text message. "Our fans always jump to the site when we upload a new album, so just imagine how crazy they'll go when they see this."

That made Brittany's heart skip a beat. The thought of anyone, even a single person, seeing her at her lowest point like this, was mortifying enough as it was.

But for it to go viral, uploaded to the web for everyone to see... All of those people, hundreds of thousands of her fans & admirers, seeing her humiliated like this...

The thought was absolutely sickening.

"You had this coming, Brittany." Jeanette continued, looking down at her struggling sibling, her fingers hovering over the send button. "Now kiss your reputation goodbye."

The tone in her voice was enough to tell the prima donna that she was serious about this, and it was going to happen if she didn't stop it.

"W- Wait!" She pleaded loudly, sounding desperate for a way out of this. "Please, don't send them, Jeanette!"

Hearing the change in tone was a surprise to the bookworm, as it seemed to be a complete turnaround.

"I'm sorry!" Brittany begged, ceasing her struggles and trying to hold back her tears. "I'll do anything you want! Just please don't post them!"

Though she could hardly believe what she was hearing, the other chipette decided to hold her actions.

"... Anything?" She asked, still not letting up on her hold.

The proposition appeared to intrigue the bookworm, who was interested to see where it would lead.

"A- Anything..." The trapped rodent answered, sounding almost ashamed.

That was all Jeanette needed.

"Hmph." She said, lowering the phone down and crossing her arms. "Kiss it."

The request was met with silence, as the lead singer wasn't sure if she should laugh or cry.

Though she wanted to do neither.

"... What?"

"You heard me." Jeanette repeated, giving her cheeks a jiggle for effect. "Put that big mouth to the only thing it's good for. Kiss my butt."

She didn't sound like she was joking. And Brittany wasn't brave enough to ask. All that bravado went out the window the moment moment realised that her most important quantity was at risk.

Her popularity.

That's what she cared about most, though her pride was a close second.

Knowing that it could all be destroyed with the press of a button had her in a position she didn't want to be.

The lead chipette hesitated, knowing she didn't have much choice. If she didn't, there would be consequences that she would never live down.

So, with much reluctance, she closed her eyes tightly and puckered her lips, leaning forward to plant a big kiss on the asscheek in front of her.

"Mmwah!"

As the sound was made, a feeling of pleasure surged through Jeanette, having her sister do this to her.

But she wasn't done yet. All those years of boasting and bragging had to be made up for, and she'd never be satisfied with a simple kiss.

"Again." She ordered.

Though she hated the idea, Brittany didn't want to disobey and risk making things worse. So, closing her eyes, she leaned in and did it again.

And again. And again, and again, and again.

Over and over, the girl pressed her lips against the buttocks, peppering them with quick little affectionate actions.

It was hard to imagine that there could be anything worse than reducing herself to this, but somehow the alternative would be worse.

The taste of the salty skin on her tongue was a torture in itself, but she could endure it. She didn't have much of a choice.

She just had to keep telling herself that it would be over soon... Or at least try to believe that, herself.

The truth, as she knew it, was that Jranette would have power over her for asnlong as she had those pics. Unless she could get her hands on her unlocked phone or convince her to delete then, she was at her mercy.

But she knew neither of those were really options for her.

"Hee hee hee~" Jeanette giggled, looking down & back at her sister with a look of victory on her cute face. "And to think, you called ME a "kiss-ass" all these years. Well who's laughing now, huh?"

There was no smart reply. Not even an attempt.

All that Brittany could do was continue her humiliating actions, trying to fight back the tears and not gag at the smell of her sis' ass.

But that wasn't enough for that sis.

"Spread my cheeks. I want you to make out with it." She commanded, as she placed her hands on her knees & bent down, presenting her rump fully. "And I mean a REAL make-out. Tongue, moaning and everything."

That made the other chipette pause, her eyes widening at the request.

She wanted her to French kiss her there?

"Do it."

That answered that.

As much as it pained her, she opened her mouth and stuck out her tongue, pressing her lips back into the sweaty crevasse until they met that disgusting orifice.

"Mmmph~"

"Hmmhmmhmhhmmm~"

The two of them let out simultaneous noises, one of enjoyment and one of disgust, as the latter's tongue slowly wormed its way inside the former's butt.

If she thought the buttocks were bad, this part was even worse.

But it had to be done, and she had to make it look real. It was her only hope of saving her reputation.

She could only hope no one would ever know that she had done something like this.

As the rodent's tongue wormed its way deeper into her sister's butt, the latter couldn't help but let out a sigh of satisfaction. But it wasn't just sexual.

This sense of power was an incredible feeling for her; she was starting to see why Brittany wanted to maintain her supposed superiority over everyone...

And now, she was going to give her a taste of her own medicine.

To Brittany's relief, her big-brained sibling stepped away from her working tongue, giving her a moment of respite from the vile activities.

Though she knew better than to think that was the end of it.

Instead, she watched in bitter anticipation as Jeanette turned back around and raised her foot up to be level with her face.

She had already taken her shoe & sock off at some point, so Brittany wasn't spared from the nose-burning torture that was her stench.

"Smell it."

Her tone said there no room for discussion. Brittany was forced to lean forward and take in the odorous musk of her sister's sweaty sole.

It was different from her butt, but it wasn't any better.

With much reluctance, the star of the trio inhaled another lungful of the noxious scent that had accumulated on her appendage, trying not to recoil & gag her throat out.

Jeanette could tell she was struggling, but she wasn't in a forgiving mood right now. Much to Brittany's misfortune.

Instead of letting up, she pushed her foot right into Brittany's face, wedging her nose right between her toes, where a good amount of the stank had built up over the day. Particularly in the last hour, thanks to gym class.

It was even worse at this proximity; there wasn't a chance that she could get away from the scent now, as Jeanette would make sure of.

"Another." She commanded, showing no signs of letting up soon. "Deeper and longer this time."

The demand made the lead singer groan in displeasure, but she knew she had no choice.

With her eyes still closed, she drew a deep breath through her nostrils, trying to ignore the way her nostrils pleaded for mercy as they filled with the rank scent of her sister's putrid pheromones.

Jeanette could practically hear her sis's internal screams for help, but they only made her more inclined to torture her even more.

Besides, why stop now? She had just treated her to a pleasing whiff of her personal smell, so why not indulge her in another sense as well?

It would be her treat.

"Alright, Brittany..." She began, sounding less commanding and more sinister now. "Give it a lick~"

As soon as those words were spoken, the nude rodent looked up in horror, feeling her heart sink as the order made its way to her brain.

"W- What...?" She squeaked, hoping she had heard wrong.

"You heard me." The girl above her replied, confirming the command. "I want you to give my foot a nice, long, tongue-bath. Clean them off, and don't miss a spot."

The order was clear, but Brittany was still stunned by the fact that this was happening.

Not only was her nose buried between the toes, but now she had to lick it?!

That was a low that she didn't think would ever happen... But the sad reality, for her, was that things could get much worse.

Against her will, the lead Chipette's tongue came out of her mouth and cautiously inched forwards, making dreaded contact with the filthy appendage just seconds later.

The taste was worse than the school's vegetarian selection, but she would've happily chosen it over the alternative.

Though that didn't mean it was easy for her; the thought that her tongue was actually licking up all the sweat & dirt from her sister's foot was enough to make her stomach churn.

Which was more than could be said for said sister.

This newfound position of power over her normally-dominant sibling was the greatest feeling Jeanette had ever had. It was like every ounce of stress that Brittany had put her through was finally coming back to bite her...

And it was doing something wonderful to her nether regions.

A kind of feeling that she usually only ever felt when thinking about Eleanor was making her get tingly, and she was enjoying it.

"You're a natural, Brittany." She teased, seeing the rodent's face scrunch up in disgust. "Looks like you're enjoying this as much as I am~"

As much as Brittany wanted to protest, she knew better than to incur her sister's bad side.

If she knew that she actually HAD a bad side, she definitely would've chosen her past words & actions a little more carefully.

But as it was, she could only face the consequences of her poor treatment of her siblings.

And there was more to come.

All of a sudden, she felt Jeanetter pull her foot away from her face, placing it back down on the floor again.

While she was thankful for the brief respite, she knew that "brief" was a generous term to give it, as she would have confirmed for her in just a second.

Sure enough, Jeanette’s next method of payback was about to show itself, when she stepped forwards again.

Her gym shorts & undies were still pulled down her legs, so her bare crotch was on clear display for Brittany's displeasure. And it didn't look any more inviting than the other end; the musky stench coming from it made Brittany thankful that she had already eaten today... Or maybe not.

Either way, it was now right in front of her, and she could make an educated guess as to where this was going.

"Let's keep that tongue busy~" The brainiac suggested, moving her hands to the top of her sister's head and pulling it forwards, right into her crotch.

As if the smell wasn't enough, the sight of it was even more horrifying for Brittany.

"Don't make me wait." Jeanette warned, as her grip tightened and the space between the two shrank. "Get back to work, or I'm posting the pics."

The reminder of what was at stake was enough to persuade her to resume her oral activities, this time on her sis's most private area.

Her tongue pressed against the slick folds & pushed in, hoping it would be enough to convince Jeanette that she had been punished enough.

Unfortunately, she would be wrong.

"Oooooh, yeah~" She sighed in relief, as the muscle worked its way inside her. "That's it~ M- Make my clitoris feel good, Brittany~"

It was sickening, but the girl had no choice.

As much as she hated it, she did as told, pushing her tongue into her sister's privates until the tip found its target, before beginning her oral assault on the sensitive nub.

The way Jenaette jerked for a second told her that she hit the target on the bullseye, but her mind wasn't focused on the success.

The taste of her sister's fluids was different than the other two, though that didn't mean it was better. She was eating out her own sister's cunt like a needy slut, and would lose everything she cared most about if she refused.

She was stuck between a rock & a hard place, whereas Jeanette was on cloud 9.

"Ahhh... Ahhhhhh~" She moaned blissfully, holding her sister in a firm enough grip as her pussy was pleasured so thoroughly.

Being the brains of the trio, it wasn't unbecoming of Jeanette to experiment and learn about new things whenever the opportunity arose. But unbeknownst to her sisters, masturbation wasn't an exception, and she had quite the prominent kinky side to her.

After all, all those books she read about animal mating habits & breeding times weren't purely for research. And that was to say nothing about the "science equipment" she secretly had under her bed.

Not to mention the times when she would "borrow" Eleanor's dirty undies from the wash basket, to indulge herself with when she was REALLY feeling the urge.

Still, having someone else's tongue working on her cunt like this was a whole new level of satisfaction, and she was glad that this was the first time experiencing such a thing.

She never would've believed that it could feel this good, but her body was proving otherwise.

"Oh, ohh, ohh, ohhhh, OOOOOHHHH~"

Before she knew it, her walls were beginning to tighten, and her hips started twitching involuntarily, thrusting themselves into Brittany's pathetic face back & forth like she was trying to hump her.

The lead singer had to hold her own face steady,  trying to focus on the degrading task at hand, as her sis's crotch thrusted wildly in her mouth.

And it wasn't long until she brought her to breaking point.

"OOOOOOHHHHH~! YYYEEEEEESSSSSS~!"

The scream of ecstasy echoed off the changing room's walls, and the squirting loads of her spunk splashed Brittany's face, forcing her to close her eyes as the disgusting discharge coating her face.

"Haahhhh... Haahhhh..." Jeanette panted as she held onto her sister's head for balance, with her climax having left her weak & drained.

It was the best one she had in a while, ever since she found Eleanor's panties the day she had a bit of an upset tummy.

Brittany, meanwhile, began to pull her face back from Jeanette's cunt, leaving a strand of stick fluids between them.

She wiped her mouth, trying to get the taste of her sis's juices out of her mouth, before looking up at the satisfied face looming above her.

That dazed smile made her blood boil, but she had no choice. She had to keep quiet, for the sake of her reputation.

Jeanette looked down at her sibling, basking in the moment, before finally getting the strength to step away from her & speak again.

"Not bad... Brittany..." She said, as she took a moment to catch her breath.

The lead singer didn't answer, though the glare she was giving her was a clear sign of her disapproval.

But if she thought that climax would be enough to satisfy her thirst for vengeance, she would be dead wrong.

***

While Brittany was thankful that Jeanette allowed her to get dressed before they left school, she knew that there was more punishment to follow, now that they arrived at the house.

Bringing her to orgasm wasn't nearly enough for her.

She had humiliated her in a way she never would've imagined, and she still had the pictures to ensure she stayed in power.

So now, she was being forced to be her lab rat for whatever little project she had been working on with Simon over the past few weeks.

Naturally, she wasn't really interested in whatever it was, and she had made a habit out of teasing the nerdy lovebirds during their hard work.

How she was regretting that, now.

Once they had gotten to the bedroom, Jeanette had her sit on the bed & wait for her, while she went to fetch the stuff she apparently required for it.

It was a tense moment of waiting on Brittany's part, not knowing what her sister had in store for her, until she re-entered the bedroom.

In her hands, she carried two things. The first was some kind of device, looking like a ray gun from some sci-fi movie or something.

But it was the second one that really had her nervous:

Eleanor's panties.

A pair straight out of her wardrobe, the perfect size to fit around her chubby waist, and the kind of white & green pattern that she liked, there was no mistaking that they belonged to their overweight sister.

And she wasn't looking forward to whatever her other sister had in mind for her.

Speaking of, Jenaette got on the bed as well, sitting across from her and placing the underwear down in front of her, as she held the device up to her.

"Now, hold still." She instructed, fiddling with the contraption's settings. "You're going to make a perfect guinea pig~"

The prima donna didn't dare to ask what she meant by that, but she would soon find out.

"Soon" being right now.

Once she had the configurations set, the nerdy Chipette turned the device on and aimed it right at her sibling.

A few boops & beeps were heard, followed by some lights flashing on & off.

And then, it happened.

Some kind of radiation beamed from the antenna, going right towards Brittany & coating her with its color.

"What the-!?" The lead singer exclaimed, feeling her body getting all tingly from whatever this doohickey was doing to her.

Reading the screen on the flat end of the contraption, Jeanette smiled at the readings that it was showing.

"Perfect." She said, lowering the device down and turning it off, watching as the beam faded.

"What... Was that...?" Her sister asked, her tone a mix of worry & curiosity. But mostly worry.

She would get her answer just a second later, when her body began to undergo some strange changes. Namely, the size of her... Everything.

To her disbelief, she began shrinking, dropping in size by the second.

Her clothes seemed not to downscale along with her, as they remained in place & regular size to leave their host nude. 

Jeanette watched with satisfaction as the arrogant girl was reduced down to a mere few inches tall, the size of her favorite teddy bear.

But there was more to come; it was time for Brittany to see how the underwear would come into play.

Somehow, through some convoluted science BS that she could never understand, her body began to infuse itself with the undergarments, merging both forms of matter into one.

The process was unbelievable to watch & feel, but it was really happening. Her body was being assimilated into one with the pair of panties in front of her.

By the time it was over, her arms, legs & torso were melted into the underwear, leaving her body from the neck upwards sticking out.

And just to make things even more humiliating for her, the part of the panties that she was sticking her head out from just HAD to be the back end of the interior.

She looked like some kind of art statement from an artist with a strangely eccentric vision.

"Wow... It worked."

Jeanette was just as surprised, as her calculations predicted this would happen, but the outcome was still something to marvel at.

The shrunken chipmunk didn't look nearly as impressed, however. Her face read closer to the word "mortified".

"J- Jeanette... What did you do to me!?" She asked, her voice squeaky, like a mouse's.

"I gave you a taste of your own medicine." The other girl answered, reaching out to pick her up & bring her to eye level. "You always like making me and El the butt of your jokes, now you get to see what it's like."

The metaphor wasn't the least bit amusing for Brittany.

"Turn me back, Jeanette!" She pleaded, struggling in her predicament, but getting nowhere fast.

Every struggle she made was futile & in vain; no matter how much she moved her head about, her new body wasn't going anywhere.

"I don't think so." Her sister sternly answered, placing the panties down. "Science waits for no-one, Brittany... Although, you'll have to wait her a moment."

With that second remark, the nerdy rodent placed the panties down on the bed, before getting up and heading to the door.

"W- Wait, don't just leave me!" Brittany demanded, sounding as angry as she did desperate.

"I'm just getting my notebook." She told her, as if it was any other day. "Just stay here. I'll be right back."

With that, she exited the room, leaving the humiliated girl to stew in her own juices.

"Oh, this can't get any worse..." She told herself, although she had a feeling that she would be proven dead wrong.

Sure enough, as if the universe could read her mind, she would hear the sound of her other sister coming home.

"Hey, girls!" Eleanor's called out from the other side of the door, sounding like it was getting closer. "Are you home?"

"Oh, no..." She muttered, feeling the pit of despair that her heart was sinking into open wider. "Please, no..."

Sure enough, to her dismay, in walked Eleanor herself, with a few crumbs around her mouth, giving away that she had been scarring down the contents of the cookie jar again.

And seeing as she was still wearing her gym uniform, rather than her bathrobe or her PJ's, accompanied with the frazzled hairstyle she was sporting, the way her face had speckles of sweat still around it and the smell emitting from her body, it was clear that she still hadn't taken her shower yet.

Apparently, she had better things to do than attend to her personal hygiene.

"Oh... I thought I heard those two talking." The chubby chipmunk remarked, looking around the room for her sisters, but not seeing them

Brittany could only watch on helplessly, as her fat sis looked around, wondering whether it would be better to alert her to her presence or not.

Unfortunately, that decision was made for her, when Eleanor's eyes fell on the undergarments lying on the bed.

Seeing the familiar pattern, the rodent stepped over and picked up the undies, her eyebrows furrowing as she looked them over.

"What are these doing here?" She pondered, appearing not to notice the head poking out from the inside of them.

The latter wasn't sure if she was glad for that, not wanting to think about how the portly girl would react to it.

Calling for her to help seemed like a sensible idea, but she also knew that she would never let her live it down.

Though she may have regretted that choice, if she knew what was about to come next.

"Oh well..." Eleanor continued, placing them back down on the bed, before reached down to the waistband of her shorts. "At least they're clean."

Brittany could only just see what was going on, but when she did, she wished rather she didn't.

Having to see Jeanette’s bare crotch today was bad enough, but now she was being tortured with the view of Eleanor's sweaty cunt as well, as the latter pulled her pants down, taking her current undies with them.

The unholy sight was the stuff of nightmares, as far as someone like Brittany was concerned. Messy & unkempt, no show of care or grooming for it, and the smell it emitted made her gag.

"There we go." Her sister said, as she stepped out of her shorts & tossed the used panties onto the bed, before reaching over to the fresh pair.

Brittany had to gasp in shock when she realised where this was going, and she knew she would need to act fast if she was going to save herself from more smelly pain.

"El, wait!" She screamed, just as her chubby sister was putting her leg through the first hole. "It's me! It's Brittany!"

Unfortunately, her cries fell on deaf ears; the pudgy chipmunk remained oblivious to what was going 9n and continued getting changed into them.

Her other foot went through and now Brittany was left trapped in place, now that Eleanor had both feet back on the ground.

"No, Eleanor!" The former shouted as best she could, hoping to reach her ears this time. "Don't put them on!"

But again, it was useless.

Instead, the sweaty girl was starting to pull them up her legs, bringing the undergarments closer and closer to her waist.

"Please, no!"

That plea was in vain as well, as she could only wait and watch in horror as the garment reached her sister's hips.

And then, with one final tug upwards, Brittany was face to face with one of the marvels of the world she never, ever wanted to see:

Eleanor's butthole.

Truly a creation of the devil himself, it was the most horrifying thing that the lead singer had ever seen.

And the fact that her own head was now sticking into it was the nail in her coffin.

The smell it emitted was the worst she had ever inhaled, the sight of her unsuspecting pucker right in front of her nose was unappetising, and she was sure she could hear something foul bubbling up from within.

If hell really did exist, no level of it could match this.

And she was certain she could die from the stink it was giving off.

"Gaaahh!" She had to gasp, once the stench hit her nostrils.

However, that came with the drawback of opening her mouth, which allowed her a taste of the repulsive pucker's musk.

If she thought just smelling it was bad, having it on her taste buds too only made things worse.

Her head was already dangerously close to her fat sis's rectum, and the slightest bit of movement would've put her even closer to the danger zone.

"This is so gross...!" She groaned, though she would find that statement to be even more appropriate just a second later.

On the opposite end of things, Eleanor seemed comfortable with her change in attire.

"Ahh, that's much better~" The porky girl told herself, running her hand around the panties, which felt strangely nicer than usual.

She had no idea why, but the way they felt around her was strangely comfortable... And she wanted them to feel even better/

So, she grabbed the waistband of them and began to shimmy them side to side, trying to get them as snugly fit around her as she could.

And all the while, Brittany was left to suffer a gruesome ordeal.

"Argh! Urgh! Ewww!" She groaned, feeling her poor face getting smushed by the flabby cheeks & coated in the sweat that decorated them.

Left & right, top & bottom, and all around, her whole face was getting painted in the disgusting fluids.

"Noooo!" She pleaded to no-one, having little faith that her sister could hear her by this point. "Stop it! Please, for the love of all that's good, STOP!""

But her cries fell on deaf ears again; the other chipette was none the wiser about her suffering.

She had no idea that her sister's head was stuck inside the panties and was being wedged up against her fat ass, nor could she ever come to that conclusion.

Instead, she kept shimmying them, getting a good feel out of her new pair of undergarments, unaware that she was also giving the trapped girl an equally torturous one.

"Mmmm~" The former moaned, finally letting go and unknwoingly leaving her sister trapped down there. "I'm kinda hungry again... I wonder if we have any cookies left?"

With that, the portly chipette stepped over to the bedroom door and opened it, before exiting the room & taking her prima donna of a sibling with her.

It wasn't until a few seconds after she left that Jeanette finally returned to her room, with a notebook in one hand and a pen in the other.

"Okay, back to- huh?"

Her sudden entrance was met with the surprise of the underwear not being where she left them.

"What...?" She asked, looking around the room for a clue. The window was closed, the effects of the transformation shouldn't have worn off yet, and she doubted they had been burgled in the short time she had been gone.

It was only when her eyes fell on the little crease on her bedsheets that she deduced what must've happened; the little indent was the perfect shape of her other sister's butt, and just the right size, too.

While it should've alarmed her to the fact that her knew she was now wearing Brittany around her butt, it didn't. Instead, she felt an enteriely different emotion coursing through her:

Arousal.

Without even trying to restrain herself, the nerdy chipmunk tossed the notebook & pen haphazardly across the room and dropped to her knees, leaning her head down and taking a forceful sniff of the area where she knew the love of her sick life was just sitting.

Hints of sweat & butt musk entered her nostrils, filling her with a euphoria that she had been craving for far too long.

"Ooooooh~" She moaned blissfully, sliding a finger down to her crotch. "You're so perfect, El~"

It was so, so SO tempting to slide her fingers in there and fingerblast herself like a story bitch in the middle of a hot mating season...

But she had a better idea.

***

"Mmmm, mm mmm~" Eleanor moaned blissfully, porking herself on the baked treats she had piled up besides her on the sofa.

Jeanette was right; food DID taste much better right after exercise. Though she couldn't exactly recall all the scientific mumbo jumbo she was told at that time of how it worked, she was glad that this theory was proven true.

And after that exhausting hour at the end of the school week, she deserved no less than to treat herself. At least as far as she was concerned.

As such, the obese rodent was busy chowing down on her snacks, while she was watching her favourite show. Truly living life to its fullest, for someone like her.

Brittany, on the other hand, couldn't have been at a lower point. Being plastered against Eleanor's titanic backside was horrific enough, but now that the latter was sitting down, squashing her against her rump even more, her face was forced right up against the pucker of the most hideous hole in the world.

She could still taste the leftover grime from whatever was in there, and the lingering scents were still strong enough to make even a skunk recoil in disgust.

"Ugh, it's so nasty..." She told herself, feeling every regret in her life manifest into physical form in this very moment.

Every breath she took was agony, and the weight was killing her. Not just the literal sense, but figuratively, too.

Being stuck in between two buttcheeks, forced to breathe in the horrible smell and unable to escape, was like a scene straight out of her worst nightmare.

There was only one way this could possibly get any worse for her, and she could only hope to the Gods above that she wouldn't-

"Hey, Eleanor!"

Jeanette's chirpy voice caught both of her sisters' attention, though only one of them could really turn their head to look at her entering the room.

The intelligent rodent came in and sat down by her sister, smiling at her like her whole world was complete. That, or she was just really happy that it was the weekend.

Either way, Eleanor didn't seem to mind her company.

"Hey, Jeanette." She replied, noticing her gym attire. "Didn't you and Brittany shower before you left?"

"Oh, no, we didn't get the chance to." The former answered, crossing her legs before resuming. "What about you? Did you wash up yet?"

"Not yet." She answered, reaching into the cookie box for another one. "I was gonna, but I got hungry. Sorry if I don't smell to great."

Jeanette shook her head, giving the other girl a reassuring smile.

"It's fine, I don't mind." She assured, moving a hand to the hem of her pants. "Actually... That's one of the things I like about you~"

The remark seemed a little unusual for her sis, but for reasons she couldn't explain, she didn't find it weird nor creepy.

The strangely pleasing feeling against her butt was making her feel something she never had experienced before, and it felt kinda nice.

"Really...?" She asked, turning her head back to the TV bashfully. "I... Always thought I smelt kind of yucky."

"Well, that's just because you've been hanging around Brittany for so long." Jeanette told her, reaching a hand over to her sis's cheek. "Between you and me, I think you're perfect~"

The comment filled Elenor's heart with warmth, but she tried not to let it show.

"Thanks, Jeanette." She replied, not thinking much about the sudden contact. "I guess you're right... Brittany's kinda a jerk."

"Yeah, she is." The nerd agreed, moving her hand away again. "But you don't have to worry about her being mean to us ever again."

That got her sis's attention.

"What do you mean?"

"Well, she's not gonna hurt us anymore." Her sister said, smiling as the memory replayed in her head for a moment. "But let's not worry about that, right now. It's just you & me, and all the time in the world~"

The way she said that statement made the chubby chipette's heart skip a beat, as her face turned a little red, not knowing where this was going.

It didn't help her nerves much when Jeanette scooted herself closer to her, placing a hand on her thigh and looking right into her eyes.

"J- Jeanette... What are you doing?" She asked, trying not to sound too worried.

Some mixed feelings were going through her mind right now, and she wasn't sure which ones were good or bad.

The way her sister was acting certainly caught her off-guard, but something was telling her that it wasn't entirely a bad thing... If at all.

Plus, whatever this feeling was in her butt was making her feel pretty relaxed about things.

So she didn't put much much resistance when Jeanette began leaning her head towards her own, smiling all the while.

"Just a little..." She whispered, bringing their faces closer. "Experiment~"

Before she realised what was about to happen, the pudgy rodent's lips met her sibling's; her first kiss was taken, in the most unexpected way possible.

Her sister, her own flesh & blood, of all people...

And it felt... Good.

The way her soft, delicate lips pressed up against hers, a passionate statement of unexpected love that went beyond family love, made for a wonderfully weird experience.

Her heart was racing & thumping at the embrace, and her mind was going blank.

She didn't even notice when her sister placed a hand on her cheek, pulling her closer for more, or when the other reached under her shirt.

Nor did she react when-

*Bbbbbrrrrrrrppppppttttttt*

... Well, she tried not to react. Not in THAT way.

Eleanor's face lit up like a Chrsitmas tree decorated entirely in red bulbs, and she froze up on the spot at the realisation of what she just did.

Expectedly, Jeanette broke the kiss and pulled away from her, looking at her with a surprised look.

Surprised, but not offended.

"S- Sorry!" The chubby chipmunk blurted out, hiding her face from her sibling in shame. "Y- You know, I- I g- get gassy when I'm nervous!"

She felt awful for doing that right here, ruining the moment between them in the most awkward way possible.

Though that was nothing compared to how Brittany was feeling.

The one and only thing that could've made this whole situation worse literally just happened.

It wasn't bad enough that she was stuck in a pair of panties with her head shoved into her sister's butt, now she was forced to endure her noxious flatulence.

No amount of medieval torture methods woudl've compared to this hell.

Her brain couldn't comprehend the words needed to describe how vile the concept was, and the stench was just as bad.

Worst of all, Eleanor's gas had nowhere to go but up her nostrils & into her mouth, leaving her to choke on the nasty fumes.

If it wasn't for her current predicament, the lead singer would've jumped off a cliff just to avoid smelling the repulsive scent.

But as things were, the only thing she could do was stay and suffer.

Back on the surface level, Jeanette didn't respond to her in the verbal sense. Instead, her face broke into a grin, and her head began to lower towards her sister's rump.

"J- Jeanette...?" Eleanor asked, daring to look over at what she was doing. "What are you-?"

Before she could finish, the girl was interrupted when her sister's nose took a deep whiff of the escaped butt fumes.

The former was shocked by what she was seeing, and waited for a response, while the latter simply breathed it in.

She grimaced by the pungent stench, but that didn't stop her from taking a second sniff, or even a third.

Eleanor was left speechless as she watched the other rodent's face scrunch up at the smell, before it lifted up to look at her again.

"Didn't I already tell you?" The latter asked, getting on her knees and crawling over. "I like the way you smell~"

The pudgy girl had no words; her jaw hung open in disbelief, and her cheeks were redder than a tomato.

She almost didn't even realise that her sister had begun to crawl on top of her, until she was looking her in the eyes again.

Nothing had ever made her feel this way before, and she couldn't help but stare back into those beautiful eyes, losing herself in them.

"In fact..." Jeanette continued, moving her hand down to her waistband. "I wouldn't mind seeing some more~"

Her fat sis didn't respond, as she watched her pull her pants down her thighs, though her underwear was left on.

She barely noticed the sinister smile that her nerdy sis sported when she saw her wearing them, still oblivious to what had happened with them.

"Eleanor..." The smart Chipette sighed, as she ran her hands over the other girl's stomach. "You're perfect... Every part of you..."

The praise was flattering, but the recipient didn't know how to respond.

"Th- Thanks." She finally managed to squeak, though she was unsure what it was even for.

"I mean it, El." Jeanette said, moving her face closer to the other girl's again. "You. You are the pinnacle of perfection~"

Eleanor wasn't sure whether her heart could handle any more, but she had no choice, as her lips were locked once again with the other's.

"Mmmmmm~" They moaned together, this time getting their tongues involved with their embrace.

As the chubby chipmunk closed her eyes and let the passion of the moment overtake her, her sister's hands moved from her stomach, and towards the undies she was wearing.

Her hand slipped down the front of them, finding their way to her sister's vulnerable pleasure hole.

Eleanor gasped into Jeanette's mouth a little at the unexpected penetration, though besides from her body tensing up, she didn't make any attempt to stop her from doing what she pleased.

She was no expert in biology, but she was pretty sure doing this kind of thing with your own family wasn't natural...

And if that was true, she didn't WANT to be "natural".

Whatever Jeanette was doing to her  she didn't want it to stop. It felt so nice for her to have her private parts being-

*PPPPPPRRRRRRBBBBBBTTTTTTTTT*

Another burst of ass gas escaped her plump rump, sounding a bit louder than the previous one.

Jeanette was surprised by the sudden release of waste air, but she didn't break the kiss off. In fact, it made her press even harder against her sis, intensifying the passion between them.

Once again, the chubby chipmunk was taken back by the assertive display of love she was being shown, yet she made no move of resistance.

The fact that her body was described as "perfect" by the most logical of the trio was flattery of the highest kind to her, and the additional fact rhat her farts didn't bother Jeanette either made her feel even better.

Brittany, meanwhile, wanted to cry. And not just from the way she was feeling from this torture.

The potent smell of Eleanor's gas was making her eyes water & her nose burn, filling her with a sense of dread as much as it filled her lungs with deadly fumes.

She had no idea what was going on up there, but could only hope & pray that it wouldn't last for too much longer, so she could get out of this already.

"Hhnnngghh... Pl... Please..." She begged to whomever may have heard her, even if that was nobody. "Save me... Or kill me..."

The sweet release of oblivion had to be better than this.

*Bbbbbrrrrrrrrrrppppppppppptttttttttttttttt*

Another burst of flatulence puffed into her face, reinvigorating the sense of disgust slowly eating away at what little sanity she had left.

It was hotter, smellier and more compressed down here than a shrink-wrapped skunk corpse, and it was starting to affect her mental state.

"I want to die..." She muttered, as she felt her eyes begin to well up with tears.

Unfortunately, that wasn't going to be the end for her. Not yet, at least.

Instead, she would have to endure more outlets of ass gas at the hands (and butt) of her chunky sister, while she and the other one continued their incestious embrace.

Eleanor was feeling like she was on cloud 9 from the incredible stimulation she was being given by Jeanette's fingers. Her sweaty nethers were being treated to such a heavenly touch that her legs were starting to tremble, her toes were curling, her breathing was getting shaky-

*PPPPPPPPPPPPSSSSSSSSHHHHHHHHHHH*

And her anus was thanking her in its own special way.

Another, even wetter fart erupted out of her anal passage, right into Brittany's unfortunate face as she was forced to take the brunt of it.

Even worse than the actual stink it gave off, the moisture of the gas was beginning to stick onto her face, coating it in the foul liquids it expelled.

And as the gas kept going, as did its host.

"Jeanette..." Eleanor moaned, having broken the kiss with her sis and basking in the feeling of getting fingered so professionally. "Oh, Jeanette...!"

Her fat sis's voice was getting more shaky and desperate, and her eyes rolled back a little as she got her pussy fingered.

She was always too nervous & innocent to indulge in this kind of activity before, so for someone with Jeanette's expertise to be her first time, after already making her feel this good about her body, was better than anything she could accomplish on her own.

"Eleanor..." The smart girl replied, giving her a lustful smile as she worked her magic fingers. "You're so beautiful... Just let it out~"

That last line told her that she meant the gas, and while she was still nervous about cutting them loose in front of someone like this, she was too high on euphoria to really care anymore.

Plus, she remembered something about Jeanette telling her that it wasn't healthy to hold them in.

So, with that in mind, her anal pucker began to relax, letting her body's waste gases come out unhindered.

*BBBBBBBBBBBBBBBBRRRRRRRRRRRRRRROOOOOOOOOOOOOOORRRRRRRRRRRRRRPPPPPPPPPPPPPPP*

A heavier blow escaped her rectum, wafting into the room with a forceful smell & sound.

The loudness of the blast made both girls blush, and Jeanette moaned at the noise it made.

"Wow~" She complimented, leaning her head down and taking a deep whiff of the pungent stench. "Eeerrghh~!"

The effects were as pleasing to her as they were repulsive, feeling her cunt dampen as much as her nose scrunch up at the smell.

She knew her sister was an exceptional girl, and now she was able to appreciate her in all her natural beauty. Including her natural gases.

Eleanor looked away in embarrassment, but Jeanette would have none of that.

"C'mere!" She ordered, moving a hand to her cheek and making her look back at her, pressing he rlips against hers once more.

This time, she asserted a bit more dominance in the embrace, wrestling her tongue with her own, while her free hand kept exploring the sweaty cunt.

The room stunk like a pig's sauna, with the sounds of the TV fading into the background, while the noises of their kissing & moaning filled their ears.

And in the middle of all that, Eleanor's asshole was still blasting out gas like an steam train's funnel, sounding like a wet, bubbling tuba every time it blew.

Jeanette had all but forgotten about Brittany by now, but even if she remembered, it would only serve to arouse her even more. If that was possible.

And speaking of, Eleanor's twat was getting overwhelmed by the intense pleasure from her sister's fingers, and it was bringing her closer to making a sticky mess.

She couldn't believe that her shy, timid, bookworm of a sister was making her feel like this, but she didn't want it to stop. Not now, and not ever.

But her body couldn't keep up with the stimulation, and her body began to spasm and jitter.

"Gaaahh! Aaaaahhh!"

The chipette's moaned loudly, while her hips bucked involuntarily as something magical was building up inside of her.

Jeanette knew what was about to happen, and at long last, she was about to make one of her biggest fantasieis come true.

Her own arousal was starting to get the best of her, but she didn't want to give in until her sister was at the same point as her.

"Let it out~" She urged, speeding up the rate of her fingers' thrusts. "Reach ejaculation, and let your juices out!"

Eleanor was at the point where she could barely hear anything else, aside from her heartbeat and her own moans, as her orgasm approached her.

"Jean... Jeanette!" She cried out, feeling her whole body tense up as the inevitable finally happened. "JEANETTE~!"

As she calculated, the nerdy rodent was treated to gushing waves of spunk erupting out of the cunt she always dreamed of violating, dousing her hand in the sticky fluids.

The pleasure of experiencing her love's first climax herself was overwhelming, as her body shuddered with immesne satisfaction.

And her own crotch was feeling a bit tingly as well, with her cunt leaking her own juices.

She would have loved nothing more than to let her own lovecream out, but she had something else in mind. A more better & fitting finale.

After waiting a moment for Eleanor's fluids to finish flooding her shorts, the smart one of the trio pulled her hand out them and brought them up to her face, giving them a look.

Seeing the clear liquid coating her fingers, knowing full well that it came from her beloved sister's pussy, sent a wave of excitement through her body, and she couldn't resist giving it a taste.

"Mmm~" She hummed blissfully, as her tongue lapped up the salty treat, sucking the fingers clean & savoring the taste of heaven itself.

Now she could die happy.

Meanwhile, Eleanor was starting to come back to reality after her first orgasm, breathing heavily and trying to calm her racing heart.

"Wha... What was...?" She asked, trying to stop her head spinning.

"That was an orgasm." Jeanette said, smiling as she lowered her hand. "Did it feel good?"

"Y- Yeah..." The other chipette admitted, looking down at her soaking panties. "Yeah, it was... Wonderful~"

She then turned her attention back to her sis, seeing the smile on her face.

"Thank you, Jeanette..." She said, leaning towards her for another kiss.

"My pleasure, El~" The former replied, leaning in as well.

Their lips pressed against each other once more, indulging in their newfound romance some more.

It was an electric moment between them, and their tongues were going back at it.

They stayed like that for a while, with the only sound filling their ears being their own muffled moans, as they kissed.

Once they broke it off, the sisters looked into one another's eyes tenderly, a feeling of peace settling over them.

"Jeanette..." Eleanor spoke, as the silence was broken. "I... I wanna do it again. Like, right now."

Her sibling's world had become complete, upon hearing that.

"El..." She said, putting her hands on her chubby cheeks. "I've waited so long to hear you say that..."

It was hard to say she was surprised by that response, but it still felt nice to know.

"I- I want to do you, too..." She admitted, feeling her cheeks burn a little. "Like, at the same time. Can we...?"

Knowing what she was tryign to ask, even if she didn't know the terminology like she did, Jeanette nodded with a smile.

"We can..." She said, pulling her own shorts & panties down and showing her privates to her sis. "And we're going to~"

The plump Chipette nodded, taking a moment to build up her confidence, before lying herself down on her back to allow Jeanette to straddle her...

Only for the latter to shake her head with a smile.

"I don't think so~" She told her, lying down the other way, beckoning her over with a finger. "You wnated to please me, and you're gonna do it the way I want~"

It took Eleanor a moment to put the pieces together, but she caught on to what it was her new lover was asking for. Though that didn't mean she understood it.

"You... Want me to be on top?" She asked, sounding concerned for the way this plan would end. "But I'm so... Are you sure?"

"I'm sure~" Jeanette confirmed, gesturing to her sweaty, scrawny body. "Trust me, there's nothing I want more~"

The reassurance didn't do too much to quell Eleanor's concerns. Not only was she at least twice Jeanette's own weight, but her bowels weren't empty yet.

Still, if this was what she wanted, then...

"O- Okay." She complied, crawling over and getting her legs on either side of her sister, who was lying flat on her back.

She took a moment to look over her body, taking in the sight of her slim figure & how much it contrasted to her own.

Jeanette smiled as her gaze ran over her body, watching her sister's eyes take in her glorious ass.

It was a view she always dreamed of but never thought she would experience, yet one she was enjoying more than anything else in the world.

All she had to do was get those silly panties out of the way, and she would reach the peak of her whole life... And there was something odd about her underwear.

What was it again? She couldn't remember; everything else in the world was a blur, after the events of the afternoon.

The only thing that mattered to her now was that she was in a position she craved to be in for so long, and her sister was willing to make her dreams come true.

"Whenever you're ready, El~" She cooed, giving her a reassuring smile. "Lie down on me~"

"Are you sure?" The portly Chipette asked, not wanting to hurt her. "I mean, I'm kinda... Bigger than you."

To answer that, Jeanette showed her devotion to this depravity in the best way possible.

Her hands reached to the waistband and yanked them down, revealing the priceless treasure that was her dream girl's private region, consisting of the two holes she had always yearned to ravish.

And following a gasp at the exposure, the pudgy rodent was met with another new pleasure, at the feeling of something wet & passionate probing at her cunt.

Jeanette's face had moved itself into position, her mouth pressing against the other's snatch and giving it a taste.

"Ah- Haaahh!" Eleanor yelped, not expecting such an advance, but welcoming it all the same.

*PPPPPRRRRRRRRRRFFFFFFFFFFFTTTTTTTTTTT*

However, as her sister was getting a taste of her vaginal fluids, her own behind had decided to let her fart again, and was louder than the others.

The fact that her anus was so close to Jeanette's face should've been cause for alarm, but the recipient didn't seem phased in the slightest.

In fact, if anything, she went in even harder into the snatch.

Eleanor moaned at the feeling, not thinking too much about what was going on at the other end of her.

Instead, her mind was focused on the euphoria that her lower regions were experiencing... And how it only seemed fair to let Jeanette indulge in it too.

So, without further ado, she moved her head as steadily as she could to her sister's snatch, and began returning the favor.

The feeling of her tongue slipping into the hole was like a dream come true for the nerdy Chipette, and her whole body shuddered.

Her eyes rolled back into her head, and her face scrunched up. This was paradise.

And with both girls indulging in one another's most private parts, the room's air was being contaminated by the foul stench of farts and the sweaty smell of their genitals. The concoction might've been enough to make any normal person pass out.

So it was a good thing that these two weren't exactly normal.

Both sisters ate each other's pussies as best as they could, all the while Elenaor let out puffs of flatulence and Jeanette's nostrils were filled with the potent aroma.

Their tongues explored the other's cunts, lapping up the juices like ice cream on a hot day, and their lips made sure to show the utmost passion.

Neithe rof them could explain why they were feeling this way, but they didn't care. All that mattered was bringing the other to the highest level of pleasure possible.

"Mmmmph~ Mmmmpphh~!" Both of them moaned together, feeling their bodies tingle with the sensations.

That same new bubbling feeling began building up in Eleanor's loins again, whereas Jeanette was very familiar with this kind of upcoming release, though it was never as intense as this.

Their bodies moved a bit more furiously; their tongues probed deeper and their hips began bucking, trying to keep up with the other's actions

They could already feel the other's vaginal fluids ready to burst, and their moans were muffled by the pussies in their mouths.

"MMMMMMMMMMMPPHHH~!"

With a loud, slurping noise, the sisters climaxed together, letting their orgasms flood their mouths and soak their faces, as they drank in the other's love juices.

It was an unforgettable moment for both of them, and a wonderful conclusion to their depraved act. Despite their opposite end sof the tally of slef-pleasure, neither one of them had ever had an orgasm as amazing as this one.

And for Jeanette, it was easily worth the wait.

Most of her energy was drained, and she was trapped under her sister's fat, sweaty, stinky body... And she couldn't have thought of a better way to spend her day if she tried.

This was everything she ever dreamed of and more. Nothing else in the world mattered to her right now.

Although, she was sure there was something else she was forgetting about... But it couldn't have been that important.
