Revenge of the Tweebs

Jim and Tim Possible; or, as their sister Kim calls them, the tweebs.

At a glance, a pretty ordinary pair of 10-year-old twin brothers. They like cartoons, video games, and being a serious pain in their sister's backside. Unlike most 10-year-old boys though, they had a pair of dangerously powerful weapons:

Their amazing intellects. Inventors, engineers, and experimenters, their technology could rival and even surpass the work of many adult scientists. In short, they were smart.

Smart enough to recognize that when they suddenly started having a pillow fight, it was later than it should have been and that they don't remember their parents getting home yet. And they certainly hadn't just fallen asleep and then popped back up.

And do we even need to get into the fact that the last thing they remember is Kim giving them a hug while they were getting a flight back home from the jungle?

Of course they knew something was odd about that, even if they lacked the attention spans to care at the moment. Later that night though, when they were in their room and turning in for bed, they did take note of the occurrence.

"Sooo, I wasn't imagining things, right?" Tim asked his brother. "We're totally missing a couple hours somewhere along the line."

Jim nodded. "Definitely. I think I remember Kim tell us to get some rest or something, and then we were suddenly waking up at home. And I think you know what that means."

Tim groaned and facepalmed. "Ughh, can't believe we let her stick those chips on our heads." Their sister pulling one over on them certainly wasn't something they were going to let stand. Harmless use of mind control or not, they much preferred having the last laugh. And so Tim's frown slowly morphed into a half-grin. "Hicka-bicka-boo?"

"Hoo-sha." Jim replied, a wider grin spreading his face while they drifted off to sleep for the night, their brains lazily kicking around a few vague ideas for retaliation.

-

When they next had some free time to work on their experiments the following day, they began plotting a bit more seriously in their room.

"So, how severe are we talking for this one?" Jim asked while beginning to scribble down a few notes for their plan. "I mean, she didn't really cause us any problems while we were under the chips' control."

Tim hummed in thought. "I'm thinking... minimal physical pain, leaning on the side of public. It was still mind control."

Jim gave a nod and jotted down those specifics. "So, can't really hurt her, and it has to humiliate her in public. Definitely need to get her at school then." Guidelines and location set, they now worked on figuring out the means.

Tim scratched his chin in thought as his brother tapped pen against paper while doing the same. Their eyes widened in fill and they grinned while simultaneously exclaiming,"Her underwear!"

A perfect choice, and accessing her clothes to make the necessary... adjustments, would be child's play (in more than one sense). Although Kim didn't know it, sneaking into her room was FAR to easy. Helped that she didn't spend too much time in it during the day, what with saving the world and teenager stuff taking up her time.

-

While Kim was out at the mall the next day, the tweebs sneaked into her room her room with the inventions they'd put together the previous day.

"Alright, let's do this." Jim said dramatically while heading over to Kim's dresser.

"Right behind ya." Tim replied, going to her closet. Opening it up, he took out a pair of his sister's jeans and her favorite green, sleeveless shirt. Reaching into his bag, he pulled out a very familiar looking red chip, the same one that Drakken had used to control Kim and Shego, and that Kim had used on him and Jim.

Now though, it had a few modifications adjusting its function.

Carefully, Tim threaded embedded it into the fabric in the back of the shirt. Their modifications would allow for mind control like this, but it could send a subtle impulse of thought into someone's mind.

Once that job was done, he moved onto her jeans. The next invention Tim pulled out of the bag was simpler: a ring made of elastics and metal. Synced up to a remote, it could be widened or shrunk at the turn of a dial. This allowed it to be constricted or loosened at any time.

Although a bit difficult, Tim managed to remove the waistband currently in her jeans and replace it with their little toy.

While Tim worked on Kim's pants and shirt, his brother dealt with an intricate task of his own.

Looking through Kim's dresser, Jim soon fund what he was looking for. "Jackpot!" he whispered, pulling out a pair of his sister's panties. He had to resist chuckling at the sight. From the front, they appeared to be a fairly normal pair of light blue granny panties (if a little wider than normal in the back), but on the back was another story.

There, spread out over the seat of the panties, he could see an image of Kim's favorite Cuddle Buddy, the Super Star Edition Pandaroo! The odd black and white body and face of the creature, complete with kangaroo appendages, start around the neck, and a smaller version of itself in its pouch, looking back.

"Yep, these are perfect." he decided and began modifying them to get an odd, tube thing into the waistband. This being one of the devices the boys had 'borrowed' from their father's lab. With a remote, one could rapidly alter the gravitational forces acting on it. A shame that the problem was getting it to function right at any size larger than a garden snake or work with any real directional control, but it was perfect for what they had in mind.

Once their work was complete, the boys put back the clothes they'd been tampering with and then quietly left the room. High fiving, they hurried back to their shared bedroom.

-

The tweebs waited a couple of days before putting their plan into action.

Pretending to be sick to stay home from school was easy enough for them. Doing so the night before, the two woke up casually the next morning and, after pretending to take some cold medicine and waiting for their mom to leave the room,the boy brought out the devices they'd be making use of today.

Sitting closely on the bed, they brought up a monitor a couple remotes, and a keyboard.

Activating their homemade spy fly, they watched through monitor as they steered it through the house, under the door of Kim's bedroom, and onto her ceiling just into to see her, still in her pajamas, going through her closet and beginning to change into her favorite green, sleeveless shirt that she was so often seen in.

The boys smirked. "Alright," Jim said, "let's get started." While Tim piloted the robot fly, Jim began typing a few things on their keyboard, sending signals to the chip in Kim's shirt.

-

"Let's see, which ones today?" Kim pondered. "I thinnnk I'll wearrrrr... these." she decided and began reaching reaching for a pair of pink slacks, only to stop as she felt a bit of a fog enter her mind before quickly clearing up. She now looked at the pants less more critically. "On second thought, nah."

Instead of those pants, she reached over and grabbed a pair of blue jeans, not knowing they'd been tampered with.

"Hmmm, these look good." Suddenly, another brief fog entered and quickly left her mind. Shaking her head, an idea came to her. "Oh, and I have just the underwear to put on with these!"

Going to her dresser, the teen got out her Pandaroo panties before closing the drawer and dropping her powder blue pajama pants, exposing her grass green panties and she stepped out of the sweatpants.

-

In their room, Jim and Tim felt their faces heat up as they watched their sister bender over and slide down her green panties, unknowingly exposing her bare bubble butt to them through the monitor.

"Crud, didn't think of this..." Jim said, eyes darting away from the screen every couple of seconds before going back, unable to look away.

"Same." Tim mumbled, equally unable to avert his eyes for more than a split second.

Thankfully, it didn't take their sister long to slide on the Pandaroo panties, tugging on the legholes a bit to get the fabric covering all of her butt's soft flesh.

As Kim got her jeans on, Jim readied the controls that would manipulate the devices in the waistbands of her jeans and panties.

-

After a quick breakfast and grabbing her backpack, Kim went outside and started her walk to school, hoping to meet up with Ron on the way.

A few feet away from her house though, she felt her panties start to ride up on her though. Grimacing a bit, Kim darted her eyes around to make sure no one was around. Seeing that she was in the clear, Kim picked the wedgie as discreetly as she could. "Better." she said, resuming her walk.

She didn't get much further though before she felt her panties riding up once more though, this time more insistently. "Urgh, seriously..." she grumbled, face scrunching up and her walk getting increasingly awkward as inch after inch of her panties rode up above her jeans and dug into her crack.

Face turning red and eyes looking about nervously, Kim tried to tuck the fabric back in, only to encounter a new problem: the waistband on her jeans was suddenly much tighter! Getting her panties into her pants was suddenly proving to be quite the challenge. One that she was forced to abandon as the saw her longtime BFF Ron Stoppable up ahead and turning towards her. "KP." he said with a wave while happily walking up to her.

Keeping her front towards him, Kim forced a smile to help hide her embarrassing predicament and greeted him back with a wave of her own. "Hey Ron."

Kim stayed two steps behind him as they walked together, making sure he wouldn't see her wedgie situation of pick up on her awkward walk. As she started trying to shove the cotton back into her jean again, she suddenly found her waistband looser and wasted no time stuffing the fabric back in.

-

Jim and Tim chuckled as they watched their sister on the monitor while she fixed her wedgie before walking right beside Ron again, now actually paying attention to what he was saying.

"Okay, the test worked perfectly." As predicted, the device replacing the waistband in her jeans let the boys tighten or loosen the fit just by turning a dial. And the device in her panties allowed them to change the pull of gravity, letting them raise the panties up with varying intensity using a remote.

Keeping the spy fly trained on his sister, Tim grinned back at his brother. "Now we to get ready for the real show."

-

As Kim and Ron entered Middleton High, the redheaded girl did her best to put her earlier predicament out of her head.

Instead, she chatted with Ron a bit more before the two parted ways after getting their things from their lockers, him going to the bathroom and her using their time before classes start to get in a few quick words with some of her fellow cheerleaders.

Kim saw a few of them (Bonnie unfortunately included) chatting by the gym's entrance and began walking up to them. "Hey girls." Kim greeted.

"Hey Kim." Tara, Crystal, and Liz greeted back while Bonnie just frowned at her.

"So have you girls thought abou-" Kim stopped as she suddenly felt a chill on her legs. The three friends before her struggled to suppress laughter while Bonnie openly grinned. Eyes going down, Kim suddenly saw that her pants were around her ankles. "Eep1"

Surprised and face tinging red, she stepped back, stumbling just a bit with her pants as they were. This, sadly, caused her to turn enough to show off her butt towards the girls. "Are those Pandaroo panties?!" Bonnie asked loudly, getting the entire hallways attention on Kim as the girl tried to cover herself with her hands. "Hahaha, wow Kim, just Kim..."

Getting more red faced by the second, Kim began to bend over pull up her pants, only to suddenly feel her panties mysteriously rocket up up and split her cheeks. "YeeEEOWIE!" Caught off guard, she slipped and fell straight over, landing on the ground with her butt sticking up embarrassingly (panties still wedged in her crack to show off her cheeks) as her classmates began to hurriedly snap photos with their phones. As Kim tried to pick herself up, Bonnie took some initiative and gave the redheads butt a nice SLAP that echoed in the hall (along with the wolf whistles that came from a few boys). "OWWwwwww..."

"Nice butt you got there Kim, maybe you should try this look more often."

Ignoring the taunt, Kim frantically moved herself into a sitting position and tried to pull up her pants. Unfortunately, although they just second ago been loose enough to fall to her ankles, the waist was now small enough that she couldn't get them past her butt cheeks.

Hopping to her feet the now fully red-faced teen rushed herself into the girls' restroom to hide her shame, frantically shutting the door behind her and bracing herself against it just in time for her panties to suddenly rise halfway up her back again. "AH! Owowowowow!" she cried, rising to her tiptoes while her back arced a bit and she stuck out her rear comically.

Biting her lip to try and quiet herself, the teenage heroine whimpered as her panties began rising higher and higher, covering her stomach in the front and going above her head in the back, lifting her toes just off the ground.

"Owwwieeee..." she let out, before gasping as whatever force was tormenting stopped and dropped her onto the ground again. "Urrgghhh..." Grabbing her panties, Kim began to he difficult task of picking her wedgie, no mean feet with how deeply they were sliced into her.

-

Back in their room, Jim and Tim were overcome with laughter, a few tears even escaping their eyes. "Oh man, this has gotta be our best work yet!" Tim said between laughs.

Jim just nodded and gave a thumbs up in reply, too out of breath from laughing so much to speak.

The only question they had now though was whether or not to keep going.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Kim Possible was most definitely NOT having a good day.

Laying on the floor of the girls’ bathroom at school, Kim sighed as she dug her Pandaroo panties out of her backside. “Ugghhh… why does this have to chafe so much…” she muttered, hissing a bit as she completely her task. Her panties were much too stretched now but lacking any other panties to change into at school, she deiced to settle for pulling her pants back up and stuffing her embarrassing undergarments back into them.

Thankfully, the waist of her jeans didn’t get stuck on her rear this time and she was able to cover herself back up.

Reaching into her pocket, she pulled out her Kimunicator. “Something here is definitely wrong.”

However, just as she was about to contact Wad to try and explain to him that something weird was going on, she felt a familiar fog cloud her mind again.

She shook her head and felt it clear up quickly but, strangely, the motivation to contact Wade also seemed to leave her. “Huhhh, what am I doing?” she asked herself. “I don’t know what’s going on, but I doubt it’s anything dangerous.”

Repocketing her Kimunicator, the teen heroine mustered up her courage and prepared to exist the bathroom to head to her first class, and hopefully not get made fun of too much after the display she’d just put on in the hallway.

If the stifled giggles of the students who saw her leave the restroom were anything to go by, the latter idea was just wishful thinking.

-

“You think we should let Wade know what we’re doing?” Jim asked his brother after having used the modified mind control chip in their sisters’ shirt to stop her from contacting her mission control.

“Well, he is pretty cool. Might even help us out.” Thinking I over a bit, Tim decided, “Maybe tomorrow if she stays suspicious. We can’t just keep making her decide not to call for help.”

Jim nodded as his brother kept their spy fly trained on Kim. They still had the rest of the school day to mess with her.

-

In spite of her earlier humiliation, Kim’s troubles seemed to be settling down as her pants and underwear were no longer bothering her. First period passed by without any problems and, currently in the middle of second period algebra, her troubles seemed to be staying over with.

She should’ve known it wouldn’t stay that way.

“Kim, do you think you can solve this one?” the teacher, a brunette woman with a green dress and similarly colored hairclip, asked.

“Sure thing, Miss Whisp.” Kim answered while standing and walking up to the board.

Just as she started picking up the chalk though, the waistband of her jeans widened significantly and gravity easily pulled her pants down to her ankles for the second time today.

“Oh not AGAIN!” Kim exclaimed as her face started to redden while her classmates began to giggle at the sight of her stretched out panties.

Placing one hand on her backside and turning around to cover the Pandaroo design on the back, she soon found her situation worsening as the back of her panties rose up high, cutting into her crack.

“EEEK!” Kim’s body stiffened and she froze was the class had a good laugh.

The teacher included, even if she was covering her mouth to try and quiet down. “M-miss Possible… hehe, are you alright…”

The embarrassed girl felt her butt clench as her panties got her to her tiptoes again. “Nooo…” she whimpered before the pull on her panties ceased and she grabbed the chalkboard’s ledge to keep from going to her knees.

Grabbing her jeans, she hastily pulled them back up, not even noticing when the waist returned to normal around her hips and then hastily began shoving her stretched panties back into the jeans.

-

Following that incident, her luck for the day didn’t get any better.

As she walked to her next class, now keeping one hand on the front of her waistband in the hopes of keeping her pants up, the tweebs used the remote synced up to the device implanted in her panties to make her underwear slowly rise up a few inches in the back (something she didn’t even notice due to their current stretched out state).

Amelia, a curvaceous and tall senior girl with wavy brown hair going down her back and garbed in a pink shirt with matching pants, did notice though.

Feeling up to exercising her rights as a senior of the school, she rushed up behind Kim and grabbed onto her panties shouting, “Wedgie!” as she pulled and drove the cotton into the younger girl’s butt.

“AhaHOWIE!” Kim cried as she unconscious dipped forward, giving the older girl the opportunity to grab onto the legholes of her Pandaroo panties and pull some more. “NYEEE! AH!”

Kim’s hips twitched a bit from the pain in her rear as she shoved the older girl back.

Unfortunately, Amelia hadn’t let go of her panties, causing them both to tumble down as Amelia fell back on her butt. The pink-clad girl angrily the front of Kim’s panties. “How DARE you!”

A squeal escaped Kim’s mouth as her panties were soon cutting into her groin.

As the redhead clutched at her groin in pain, she vaguely heard Amelia mumble something about paying her back more later.

-

Eventually, Kim finished up her last class of the day: Gym.

Currently the last girl still showering, Kim enjoyed the feeling of the water running over her. Especially as it made contact with her chafed butt crack, causing her to sigh.

When she was finally satisfied with her state of cleanliness, she turned off the water and reached over to grab her towel but panicked when she couldn’t feel it hanging up. “Seriously!” she whisper-yelled. “Have I suddenly traded luck with Ron or something?”

At the very least though, it would just be other girls waiting for her outside the shower. So she stepped out of it to get to her locker but stopped just two feet along the way when she saw the rest of the girls staring at her.

Sighing, she said, “Really girls? Why all the stares?”

SNAP!

“OWIE!” Kim cried as she felt a towel snap against her right buttock, leaving a red mark and making it sting as it wiggled a bit. Whirling around as she placed a hand on the sore spot to rub it. “Bonnie!”

Kim glared at the tan girl holding the towel (Kim’s towel) but was surprised as some of the other girls rushed up behind her and grabbed her arms.

“What the heck is- MEEP!” Kim squeaked as another towel was whipped against her booty by a blonde girl wearing blue.

“Just so you know, it’s not personal this time.” Bonnie explained. “Amelia promised us some of the gourmet food from the seniors’ table if we did this. Well, I’d have one it for free, but the others needed some incentive.

“Come on girls! Can’t we talk abou-“

SNAP!

“OOOWWW!” Kim inhaled and exhaled I pain as the blonde snapped the towel against her butt again.

Bonnie and Hope took up positions alongside the blonde with there own towels. “Sorry not sorry, Kim, but come on. You should know not to get on a senior’s bad side.”

The locker room was soon filled with the sound of twisted up towels whipping against flesh and Kim’s shrieks as her bottom was given a nice coating of welts.

The girls finally stopped when the last bell of the day rang a few minutes.

Before leaving with the other girls, Bonnie slapped her palm against Kim’s bottom, making the redhead whimper. “Catch ya, Kim.” she called, walking away with a smile.

-

Getting home that day, and grateful that her parents weren’t home yet to ask her why she was walking funny and lightly rubbing her sore bottom, Kim tossed the stretched-out panties she’d been wearing in the trash while grabbing an ice pack from the fridge and placing it down the back of her jeans.

“Ohhhh yeahhhh…” she moaned as the cold granted her some relief.

Marching up to her room, she never noticed when her brother sneaked down into the kitchen to remove the gravity manipulating tubing from her wrecked panties.

After all, they may want to use it again in the future.
