She Owed Him One

"Are we seriously doing this?" Tuesday X, her spiked and messy hair changed to a teal color today, asked her brother as she followed him to his room.

"Hey, you agreed to owe me one if I got you down." Truman pointed out, smugly reminding her of the event just three days ago. "And I did."

"Yeah, after BURNING my butt." she argued as they stood before his bedroom door. A devious smile formed on her lips as he began to open it. "Speaking of which…"

Quickly and ruthlessly, she stuck a hand down the back of his shorts, grabbed onto his tighty whities, and gave them a devastating PULL. "AAAGGHHHOWWW!" he cried as his briefs stretched all the way up and over his head with enough speed that the friction produced actual smoke between his buttocks as his waistband was hooked onto his forehead nice and tight. "Nyyygggghhh!"

"I've been meaning to get you back for that." The agony her butt had been experiencing at the time was the only thing that had distracted her from doing so and put it out of her mind. "Thanks for reminding me."

"Uuurrrgghh…" he grunted, head tilted back and hunched over as he pried his briefs off of his head. "I told you, that was an ACCIDENT!" he lied.

"Surrrre it was." she sarcastically replied with an eyeroll. "Just be glad that you actually got me down, or you'd be walking funny for a week from the chafing I'd give your crack."

Growling a bit as he stuffed his stretched-out underwear back into his shorts, he tried to calm down. Just wait a bit longer and then she'll be the one chafing and screaming. he reminded himself. "Whatever. Just remember, you owe me. One free experiment, no consequences."

"ONLY if you don't mutate me or causing any lasting-"

"Long-lasting!" he corrected, reminding her of what they'd agreed on this morning.

"…any long-lasting harm." she finished. She'd let him negotiate up to the 'long-lasting' part on the basis that equipment testing (especially when it came to new gadgets) could get very unintentionally hazardous.

That, and because he'd offered her the last of the extra-large pancakes at breakfast that morning as part of the deal and she'd been feeling a little extra hungry at the time. Stupid hunger… she though with regret about having caved that easily at the time.

Truman's bedroom door now opened, the siblings began walking in over to what the younger of them had prepared.

Past all the seemingly random chemicals and engineering parts was a glass booth, the glass likely being of the more durable and resistant type, that had a drain in the middle of it (likely to get rid of water from the emergency sprinkler inside if it was set off) and a chair could be seen inside against one of the booth's back wall.

The chair was a recliner chair with a chrome color on its plush exterior. Armrests were, of course, built on the sides, there was a leg rest deployable by lever on the righthand side, and it just overall looked like it would be very comfy to sit in.

"Here she is." Truman said, gesturing at it.

"You built a chair?" Tuesday asked, arms crossed and a look on her face that gave off an air of being confused and underwhelmed.

"Try THE chair." Truman replied. "Beneath each armrest, in addition to cupholders, is an array of buttons activating it's many features. Gravity defying hover fields, micro-boosters, cyber-arms, lasers, massage function, high definition screens, speakers, Wi-Fi, ALL the works!"

"What, did you put a shower, sink, and toilet in it too?" was the sarcastic reply Tuesday used to hide her genuine interest in the object before her.

"Still in development." Truman muttered, not sounding happy about being unable to get his char furnished with plumbing.

His sister tilted his head now. "And just to be clear, you want ME to test out YOUR incredible new super chair?" she asked suspiciously.

"Hey, if it turns out I missed some small, really important detail that could backfire horribly on the user, better you be the one to figure it out." he replied.

Glaring at her brother, Tuesday reached down and snatched him off the ground by the seat of his pants. "Hey!" he shouted as she tossed him up, hand then shooting out to grab where she saw his already stretched briefs slipping out. "You said no consequencccceeEEEESSS! AGGGHH!"

His pain-filled hisses and grunting as she pulled on his briefs for the second time that day turned her glare into a grin as she held him in a dangling wedgie. "Not a consequence of the experiment." she defended, giving him a bounce that made him squeak and added another couple of inches onto his undies. "This is just for what you said."

Not stopping, she continued bouncing the boy, adding more and more inches to the cotton. "OowowowowoOWOWWWWIIEEE!" Soon getting the Truman's underwear long enough that he only hovered a couple of inches off the ground, she tossed him up and caught the underwear in the middle

Lifting him up a bit higher to look him in the eyes, she said, "And now I'm done." That was followed by unceremoniously dropping him onto his wedgied and clenched up buttocks.

"Oooooowwwww…" Biting his bottom lip as he inhaled and exhaled through his nose, he scowled at his sister for her loophole abuse. Calming down and then getting back to his feet while once again digging his underwear out of his crack after unclenching his glutes, another grunt and hiss left his mouth as he managed it. "Will you just, AGH, get in the booth and try out the chair?!"

"Alright, alright." she said, going to the booth and getting inside it. Her voice coming in through its speakers do to the booth's natural soundproofing, he heard her ask, "So how do I test it?"

Adjusting the microphone outside the booth on its control panel, he answered, "It's got a DNA scanner built in for security. Anyone with enough X family DNA, like you, is good to sit. So, feel free to plant those giant pillows you call butt cheeks any time now."

"There's nothing wrong with my butt!" she shouted angrily.

"Yeah, yeah. Whatever helps you sleep at night. Just sit down already."

Giving a growl of her own, she stomped over to the chair, turned, and sat herself down on it with her legs crossed. "Okay, now what?"

"Put your arms on the rests and the DNA scan will start. That unlocks the controls in the armrests." he explained.

Doing as he said, she triggered a scan.

And then shackles from the armrests suddenly locked around her wrists. "What the…" Uncrossing her legs to try and forcibly stand up as she pulled at the arm restraints, Tuesday shouted, "Truman! What is this?!"

The boy held back a chuckled and, thankful that she couldn't see the grin on his face right now, lied, "I don't know. You triggered the security system somehow. Hang on…"

As he pretended to try and do something helpful with the booth's control panel, Tuesday struggled harder but felt herself freeze up as a pair of metal arms, each sporting three long fingers, came out of the chair's back. "Uhhh, Truman!"

"Don't worry, I didn't put anything lethal or too bad I the security." he responded, only diminishing her worry by the smallest amount.

"Then what does it do?!" she demanded to know as the metal arms bent around towards the front of her.

"Oh, you'll probably find out in a second." he answered. And she did.

The metal fingers grabbed onto her checkered skirt and began tugging it off of her. "Hey! Quit that, you stupid perv bots!" She tried curling up her legs to stop the process, but the arms were long enough and capable enough of bending that they still got it off of her. "You made the security to STRIP people!" she shouted at her brother.

Beneath her tights, one could now make out traces of her pink granny panties, especially where the grey fabric was extra thin and stretched in the back to the point of being see-through.

"Not exactly." Truman replied, trying to sound sheepish as he kept up his act.

A slot that opened up on the chairs soft back, the opening at the same height and Tuesday's lean waist. From that slot emerged a spool like one would expect wires or cables to be coiled around.

Two small hooks on the spool latched onto the back of Tuesday's grey tights and pink panties, the teen yelping at the cool touch of the metal. "What was that?!" Tugging on her panties I the process, the spool then retreated back into its slot. "Eep!"

That little tug was nothing though.

Slowly, the spool began to rotate and wind her panties around itself. "Nyyyggghhh… Are you kidding meeee?!" she shouted, voice going up octave by octave as her panties were pulled and wound tighter and tighter, slowly digging into her buttocks and making the soft globes clench up.

Though her panties were stretchy, getting longer and longer as the spool spun, her the back of her tights were shredded almost instantly. Tuesday's right eye twitched as her wedgie worsened, sucking in her bottom lip and whimpering as the spool began to speed up a little.

As if that weren't enough, the metal hands descended again and grabbed onto the FRONT of her panties, yanked them up harshly and adding about six inches in length to that side with just the one pull. "AAAAYYYYEEEEE!" Tuesday lifted up her hips on instinct to lessen the tension and friction being applied to her groin, which had the effect of worsening the wedgie she was getting from behind. "AAGGGHHH!"

The metal hands tugged up on her panties again, making her squeal and her hips rise as the spool's continuous turned tugged her panties the opposite way and brought her butt back down as she grunted. Then the hands tugged again.

A brutal game of tug of war ensued as she was yanked bank and forth, her groin and butt flossed and chafed in a squeaky clean wedgie that kept her squealing and grunting for a couple of minutes until…

RRRRIIIP

Mercifully, her durable pink panties finally ripped, tearing in two and she sucked in a breath of air in relief, beginning to inhale and exhale as she collapsed in her soft seat to recover from her chafing. "Finalllyyyyy…" she whimpered out.

"Ummm, Tues, it's actually not over yet…" Truman warned.

"What?" she asked weakly with fearful disbelief in her voice right before a third metal restraint came out of the chair's back and two more popped out around her legs. "Oh no…"

And then, an electrical current ran through the chair's seat.

"OWWW!" she shouted, trying and failing to sit up as a series of electroshocks assaulted her backside, the chair's restraints ensuring that she couldn't sit up. "Ooowoww! Nnnyyyggghhh!"

The shocks stopped then.

They stopped because the seat was now able to rapidly heat up, the temperature quickly turning unbearable as it the electricity previously rushing through it allowed it to rapidly approach hot coal levels. "AAAHHHOOOWWW! TRUUUMAAANNNNN!" she shrieked, her bare butt squirming on the hot surface.

"Just give me a couple minutes, I think I found the problem!" her brother shouted, pretending that he'd just made some progress.

"MINUTES!" she screamed, voice getting strained from all her squealing earlier as her rump was now getting roasted. "OwowowowOWWWWIIIEEE! HUURRRRYYYYY!"

"Working on it!" he called back.

"AAAAAHHHHOOOWWIIIEEE!" A couple of minutes went by. Then three. Then four. Her butt was turning red from the heat and she was starting to lose the ability to scream as tears welled up in her eyes, the liquid soon falling down her face and making her mascara run.

At the five-and-a-half-minute mark Truman finally decided she'd had enough and just hit the emergency release button. "Got it!"

"HYYYYAAHHHOWWW!" shrieked his sister, leaping out of the chair as her restraints her undone and panting heavily as she laid on the ground with her reddened rear end raised upward.

As a small mercy, Truman activated the emergency sprinkler in the booth, letting cold water rain down on her and drawing a whimper from her as it began to cool her buttocks before flowing down the booth's drain.

Chuckling, Truman opened up the booth and said, "So get this. I was looking for the problem and here it is. After setting the DNA lock to X family DNA, I also added in Rex's DNA so that the chair wouldn't freak out anytime he, like puppies always do, jumps on the chair without permission. But, heheh, I accidentally deleted OUR DNA when I entered his. It's an easy fix though."

Soaking wet on the ground, she glared up at him. "You are sooooo lucky I'm actually respecting our deal." she muttered, voice tired.

"Yep! That's why I made it with you." he said with a grin, feeling luckier about the fact that he was such a good actor.
