Jason demonstrates the device to Tyler's older sister

Jason had kept what he had seen the device do to Ms. Watson under wraps for the time being. Jason trusted Tyler, but he was not sure how he would react. Jason wanted to fully understand how it had happened and what exactly it meant for their project before sharing anything. Ms. Watson had called in sick the rest of the week, so Tyler had taken the device back to his house for storage until they could use the school again. Jason was itching to do some more tests, but his house did not have any space for the project.

That weekend though, Tyler was going out of town somewhere with his girlfriend. Jason was about to go crazy thinking about the static manipulator and what it could do, so before his friend left, Jason asked if he could work out of his basement for the weekend. Tyler had hesitated at first, not wanting to miss out on any of the project. However, he ultimately relented when he could see how enthusiastic Jason was.

"Alright dude, just don't break anything. And, most importantly, don't make any ground breaking discoveries without me!" Tyler told his friend over the phone.

"Well c'mon, how am I supposed to not do that? I'm the brains of this whole thing after all."

Tyler told him that his parents would let him in on Saturday whenever he showed up. To Jason's surprise, it was not Tyler's parents who opened the door for him when he arrived, but Tyler's older sister Jessie.

"Oh! Uh, hey Jessie. Should I tell your parents that I'm here?"

"They're gonna be gone for most of the day. I'll be here doing laundry and studying if you need anything."

Jessie was three years older than Tyler and Jason, and had gone off to college before the two young men had become friends. Jason had met her once or twice, but he barely knew anything about her other than the fact she was his friend's older sister. His friend's hot older sister, he might add. As she walked away from him, Jason took in the way her tight spandex athletic shorts hugged her toned rear. Even the loose sweater she wore somehow betrayed a curvy but tight figure beneath it. Jason shook his head and walked off to find his way down to the basement. He needed to focus.

Down in the basement, he set up the static manipulator on a workbench in the center of the room and plugged everything in. He set all the dials and outputs to null and fired it up. It let out a low hum when it activated, but as of now it should not be affecting anything. Only he had seen what this thing had caused Ms. Watson's panties to do, so he had to try and remember exactly the parameters they had been operating under. He spent the next thirty odd minutes adjusting the outputs and power regulation to try and recreate the affect on a washcloth he had taken from above a laundry machine on the other side of the basement.

After another half hour with little success, Jason finally managed to get a reaction. The needle on the electromagnetic feedback dial began to slightly flicker up and down and the washcloth twitched, sliding a few inches left then right.

"Now we're getting somewhere." Jason muttered aloud to the empty basement.

He continued toying with the device for a little while longer, making the washcloth do more and more complex maneuvers as it slid around the table. For some reason though, he was unable to get it to lift up into the air and fly around the room like he wanted. He did not understand it. The other day, under the effect of the static manipulator, Ms. Watson's panties had not only lifted her into the air, they had taken his teacher with them! He had to be missing something.

Leaving the static manipulator still humming and communing with the washcloth, he walked around the table to look at the twitching towelette.

"What is with this thing?" He muttered, slowly reaching out a finger to prod the washcloth.

Jason expected to feel a slight tingle or small shock from the cloth when he touched it. That was not what happened. Once his finger poked the fabric, every article of clothing he was wearing from his t-shirt to his boxers and socks suddenly tensed and hummed all around him hitting him with tickling electric jolts as they tossed him up and away from the table.

"Shit!" He cried as he sailed back through the air through the basement.

Once he stopped touching the washcloth, the affects on his clothes had immediately vanished, but the initial **** was still propelling him through the air. Luckily for Jason, Tyler's family had a plush cushioned couch pushed away against the far side of the basement surrounded by an odd assortment of bagged clothes that needed to be donated. The young man crashed into them with a grunt before pulling himself up into a seated position as he tried to catch his breath. He quickly patted himself down and checked for injuries, but the only issue he had was his heart thumping in his chest with adrenaline.

"What the fuck..." He muttered excitedly, pulling himself up from the couch and running back over to the device.

He ran his eyes and fingers over the dials and inputs as he tried to figure out what just happened. Something was still not clicking in his head, but he was starting to get a better idea of the effects this thing could cause. He looked back over his shoulder as he heard the basement door open above him before footsteps began to descend the steps.

"Did you shock yourself or something?" Tyler's older sister Jessie asked with a hint of sarcasm as she walked passed Jason with a bucket of laundry in her hands.

"Uh, well, sort of. I'm not really sure..."

Jessie placed her clothes down next to the washing machine where Tyler had borrowed the washcloth from and began to load them.

"So what does that thing do anyways? Tyler said something about an electromagnet or something."

"Well, it's supposed to be able to manipulate static electricity so we can control and command atomic bonds and maybe even get a better understanding of the quantum field underlying..."

"Static electricity?" Jessie interrupted as she unloaded clean clothes from the dryer into another bucket. "Is that supposed to like help with my laundry or something."

While Jessie had interrupted him, Jason had already begin to lose his train of thought as he stared at the girl's backside when she bent over in her tight spandex shorts to unload the dryer full of clothes.

"Uh, well yeah, it might could help with that." Jessie stood back up and turned to look at him with the bucket of clothes held in front of her before Jason continued. "Last time we used this we accidentally, uh, well we sort of made the thing lift our teacher up into the air."

This seemed to pique Jessie's curiosity.

"Lift her up into the air? How the hell did that thing do that?" She approached the table and eyed the metal ball seated atop its small tower of coils and wires.

"Uh, well..." Jason awkwardly rubbed the back of his head. "We accidentally attuned the thing to her, uh, well her underwear." Jessie turned and looked at Jason with a raised eyebrow. "On accident! She was in the other room and when I went to check she was already hovering three feet off the ground."

Jessie laughed at this. "Yeah right. What, did it fry her ass or something like that?"

An image of Ms. Watson Pinned up against the wall by her underwear as the tickling electric shocks made her orgasm flashed across Jason's memory.

"Well, I think she kind of enjoyed it..."

Jessie laughed again, before setting down the load of laundry at her feet. "Alright, show me."

"Uh, what?"

"Lift me up into the air then! Tyler is always going on about how smart he is, I bet this is all bullshit."

Jason blinked a few times before shaking his head to clear it. He was about to tell Jessie that he could not or would do it, but then he got a better idea.

"Well, alright, I guess I can try to replicate what we did. What kind of underwear are you wearing?"

"Excuse me?" Jessie let out an incredulous laugh.

"What kind of underwear are you wearing?" Jason repeated in an earnest voice. When Jessie scoffed, he continued. "Hey look, I told you, whatever we did made Ms. Watson's panties lift her up into the air. I gotta know what you're wearing if I'm going to replicate it."

"Of course...I see." A smirk was threatening to creep up her lips as she shook her head.

Jason had expected her to think that he was teasing and leave. To his shock, she instead hooked her thumbs into the sides of her spandex shorts and pulled them down to her thighs to expose the red lacy thong panties she was wearing underneath. She turned her body from side to side to give Jason a full view of her front and toned curvy ass where her underwear disappeared between her cheeks.

"Good enough?" She asked before pulling her shorts back up into place.

Jason was momentarily speechless. He was definitely a bit inexperienced with girls and relationships, but he knew it was probably not great to be messing around with his friend's older sister. The feeling of his cock threatening to swell up in his briefs was certainly not helping matters either. Of course, if she really wanted to see what this thing could do...

"Uuhhh..." He quickly cleared his throat. "Wow. I mean yep! Yes. Yeah that'll, uh, that's great..."

Jason quickly walked back behind the controls to the device and hoped that the subtle bulge forming against the crotch of his athletic pants was not noticeable. He thought he heard Jessie chuckle to herself as he tried to attune the device to Jessie's position and her underwear. Now that he had worked with this thing a bit more, it was not too hard to calibrate it to something similar to what they had it set to with Ms. Watson.

"Ready?" Jason looked up from the controls across the side of the table to where Jessie was waiting.

"Sure. So do I like touch the weird metal sphere or-nnnghhaa!" Jessie's eyes widened and she pressed a hand against her crotch and stumbled back a few steps.

Jason had lowered the power output of the device to minimal levels. After being tossed across the basement, he did not want to accidentally do the same to Tyler's sister. If he understood this device correctly, Jessie's underwear should be sending waves of small tickling electric touches flowing around between her legs and up her crotch. Based on her reaction, Jason guessed it was working.

"What the fuck!?" Jessie let out a gasping laugh as she looked up and down from her crotch to Jason.

"Told you it worked." Jason smirked before powering down the device.

With the static manipulator now turned off, Jessie slowly removed her hand from her crotch and gave Jason a look that almost seemed...disappointed? That could not be right.

"Well...I definitely felt something." Jessie spoke in a way that made Jason think he might have just fucked up. "But...It definitely didn't lift me into the air!"

Jason blinked a few times. Wait, was she enjoying this?

"Well yeah, I had it on low power. I didn't want to freak you out or anything."

"Mmm, sure. I bet that little tickling feeling is all it does."

"What...no it can do...wanna see?!" Jason was getting a bit flustered, and almost offended at the girl's dismissiveness.

"Sure. If you can..." Jessie smirked as she looked at him.

"Alright, if you say so." Jason began to power the static manipulator back up again. "If I can..." He muttered resentfully under his voice.

He set the device back to the low setting it was previously on, and then fired it up with a low hum. Jessie jumped with a tiny noise as the tickling staticky feeling once more began to emit from her underwear.

"So what you're feeling now is the low setting." Jason manipulated some dials as he began to ready the output change.

"Mmmhmmm..." Jessie bit her lip and closed her eyes momentarily.

"Now if I start to dial up the output..." Jason began to slowly twist one of the dials and Jessie gasped as she was lifted up onto her tip toes while whatever was happening to her underwear began to increase. "...the feedback loop begins to intensify and the localized field being generated in your underwear increases in strength."

"What the fuck..." Jessie groaned in a way that made her sound quite pleased with what she was feeling.

"And with greater field strength, I can cause more momentum shifts."

Jason manipulated a few more controls, and Jessie yelped as she was suddenly propelled forwards by the electric humming in her underwear. She stumbled towards Jason and the table, and caught herself against its edge as the **** eased its acceleration.

"Holy shit Jason!"

Jessie bent forwards against her grip on the table and slowly swayed her hips against the sensations projecting up between her legs from the device manipulating her panties. Jason realized that he was ogling his friend's sister, and noticed with a start that she was staring down between his legs at a noticeable bulge forming against the front of his sweatpants.

"Jason...Jason this feels incredible!"

"I, um, well good. Here, I should probably turn it off."

"No!" Jessie suddenly looked at him with a wild look in her eye. "Holy shit Jason, don't turn it off, turn it up!"

Jason blinked a few times as he looked at Jessie. He had just been ogling her body and she had clearly noticed it. She had to be enjoying whatever the device was sending up between her legs, and she wanted more?

"...Alright."

He turned a few more dials to power up the output and Jessie squealed as the sensations sent up her crotch intensified and amplified.

"Holy shit...don't stop...don't stop..." Jessie groaned and rocked up and down on her feet. "Jason this feels...Jason...Jason I..."

Jessie gripped the edge of the table in a white knuckled grasp as her mouth fell open in a silent moan. She managed a little squeak as a shudder passed through her. Had she just...

"Oh my god!" She whined in pleasure before her eyes once again met Jason's gaze. "Jason..."

Before Jason could properly react to what had just happened, Jessie moved down the table and grabbed him. For half a heartbeat the young man thought that his friend's sister was about to berate or hit him for what he had just done with the machine, until she pulled him against her body and began to lustfully kiss his lips while her hand slid down between his legs to fondle his stiffening rod. The static manipulator still hummed on the table next to them, and Jason tried to blindly reach over to turn it off before he became too distracted by the beautiful woman trying to fuck him. The next thing he knew, Jessie's hand slid down the waistband of his sweatpants and briefs to grip his now throbbing erection.

"Holy shit, Jessie..." Jason managed to stutter between kisses.

As his hand fumbled with the controls of the static manipulator, he knocked a hand against a dial and accidentally turned it up. The device began to hum at a higher intensity in response and Jessie suddenly pulled her lips back with a shocked gasp.

"Ooooh holy fuck!"

Jessie groaned and Jason felt her knees almost buckle against him. He was not totally sure what he had done, but if he had to guess, he had probably just turned up whatever Jessie's panties were doing between her legs up to eleven. Jessie held onto his shoulders as a wave of pleasure shook through her body and he felt her hips begin to thrust against his own. Jason was still in shock that this was actually happening, but almost immediately his body responded with a surge of adrenaline. Jessie's head rolled back slightly with a moan before she leaned back forwards to stare into his eyes with a gaze of determination and lust.

The next thing he knew, Jason had his back pressed against the edge of the table as Jessie dropped to her knees. She pulled his sweatpants and briefs down with her, and his rock hard member sprung out into the open air in front of Jessie's face. Jason was unable to contain a groan when she took his cock into her mouth and swallowed it up to the hilt.

"Oh my god..."

Jason groaned as she worked her mouth up and down his shaft as one of her hands gripped his ass and and the other assisted her hungry tongue. Jason could hear her muffled moans coming up from his waist as her charged panties arced energy and tingling electric touches into her nethers while she sucked him off. While he was a little sexually inexperienced himself, Jason could tell that Jessie was not. The way her tongue and mouth swirled and swallowed his dick was one of the most incredible sensations he had ever felt, and as she continued, he could feel himself creeping closer and closer to coming.

"Oh god Jessie..."

This woman was his friend's older sister, and Jason knew he should probably be trying to to stop her from taking things so far. But she just felt so damn good. Jason ran one hand through her hair while another braced himself against the table. He slowly thrusted his hips in time with her movements when he began to feel something both strange and wonderful. Tiny tickling arcs of electricity began to dance off Jessie's tongue as it swirled around his cock while she sucked him off. Jason's mind was already too lost in a haze of lust to process how this was happening and what it must be making Jessie feel. Between the sounds she was making below and the new fervor she was beginning to gobble his cock with, Jason had to guess it felt good.

This was all beginning to be too much for Jason to handle, and as the seconds passed he could feel himself getting closer and closer to coming.

"Jessie I...I'm about..."

Breathless, Jason was barely able to speak, but the dark haired girl knew what he meant. Instead of pulling back, Jessie went all in on his throbbing member, and then the damn broke loose.

"Fuuuck!"

Jason roared as he blasted his load into Jessie's hungry mouth. His vision momentarily went white as his brain zeroed out from the overloading sensations of the powerful orgasm. In that moment, something odd happened. Maybe it was a coincidence of timing, maybe it was the exchange of matter between the two of them affecting the electromagnetic field of the static manipulator, or maybe it was something else entirely. As Jason shot his seed down Jessie's throat, the static manipulator began to whine and shudder, and Jessie suddenly pulled herself back from Jason's hips with a shuddering cry of pleasure as every article of clothing she was wearing, save her panties, flew off her body in flurrying waves of fabric. The **** of this tossed her back onto her ass to leave her splayed out on the ground before Jason. On the table next to him, the static manipulator began to slowly wind down to a stop as some sort of breaker finally seemed to have tripped.

Both of them stayed where they were for a moment, panting and recovering from the insane sexual experience. Jason's recently drained cock still stood stiff before him as he surveyed the incredible body of the near naked woman equally eyeing him up from the floor. His senses were coming back to him after that colossal orgasm had reset his brain, and he struggled to think of something to say to his friend's sister.

On the floor, Jessie slowly began to pull herself back up to stand before him. Doing nothing to cover her exposed body, she slowly licked a last bit of his seed from her lips as she surveyed the remaining tatters of her clothes strewn around the basement before her eyes came back to meet his.

"Well..." She spoke slowly as a devilish smirk began to trace across her lips. "I guess you weren't lying."
