“Are you still messing with that?” Jillian asked her brother “What does it even do? Why do you waste so much time inventing stuff that will never work?”
Matt just sighed “It will work. I’m sure of it this time and that’s why I do it. Past failures do not represent future failure; I learn from every one of my past experiments. I build upon them and perfect them until they do work”
“So what does this one do?” Jillian asked.
“Well funny that you should ask because it’s designed to improve empathy in someone; get them to truly understand someone else. Something that you definitely need help with”
“I’ll never understand you that’s for sure” Jillian replied.
“You go around in your own little world. You don’t understand me and I don’t want you to but you also complain about how you don’t understand your teachers or Mom…” Matt just shook his head.
“Whatever…if that thing really works, prove it to me” Jillian said putting her hands on her hips.
“I haven’t tested it on anything yet, it could be dangerous…”
“Chicken” Jillian said. “Your inventions suck and they don’t work and you’re afraid”
Matt looked at his sister standing before him with such a smug look on her face.
Jillian at 16 stood 5’8” with thick wavy blonde hair, bright green eyes and perfect bone structure. She was a botch and could get away with it. She wore a cream colored crop top and short black shorts giving him a look of ‘I dare you’
“What is going on down here? I can hear you two all the way up in my room?” their mother Janet said coming down the stairs with a basket full of laundry.
“You wouldn’t understand Mom” Jillian said immediately upon hearing her voice behind her.
“No but maybe you should” Matt said finally having enough of his sister’s attitude.
Josh lifted up his invention which looked like a scanner from a grocery store. He pointed it at his sister and pressed the trigger.
Jillian seemed to freeze; her jaw dropped and her eyes widened.
On the computer screen in front of Matt, an image of her appeared along with all vital statistics scrolling up at once.
Janet took another step closer more than a bit confused “What’s going on Matthew?”
Matt pointed the scanner at his Mom and pressed the button down one more time.
Now an image of his Mother popped up on the screen and all of her vital statistics appeared scrolling up until they went into a split screen.
Janet dropped the laundry basket and it crashed down at her feet. At 44 years old, Janet stood in stark contrast to her daughter. Janet was an even 5’ tall and was a much stouter woman. Still dressed in her skirt and blouse from her job at the bank, she was barefoot. Not fat per se but thick and solid. Her dark brown hair and eyes stared forward blinking as Matt clicked away on the keyboard.
With hitting the enter key both Jillian and Janet snapped back to.
“What the hell was that about you freak?!” Janet yelled. She immediately clamped her hand over her mouth in shock and embarrassment.
“Watch your mouth young lady!” Jillian said before looking on in equal shock.
“It worked” Matt said breathlessly. He stood up slowly looking at his Mom and sister who could only stare back in confusion.
“What worked?” Janet asked.
“My device! HAHA! This is amazing! I built a device to swap two people’s minds! It was to teach empathy…the whole walk a mile in my shoes thing! I did it!”
“So…” Jillian began to say.
“Your thoughts about me and Mom’s thoughts about me swapped! That’s why Mom yelled at me like you would and you reacted like Mom would!” Matt was very excited and worked up. He was smiling from ear to ear and running his hands through his hair laughing and bouncing around.
Janet and Jillian looked at each other in shock.
“You can actually control our thoughts?!” Janet said alarmed.
“Not so much as control your thoughts but control who you’re thinking like. I switched a part of each of your brains. You literally have Jillian’s thoughts about me and she has yours!”
“This sounds dangerous” Janet said. “I think that you should undo whatever you just did…this doesn’t sound right at all”
Matt wasn’t paying attention to his screen. Numbers were beginning to change, running up or down. He sat down and saw the active screen in front of him “Fine…I’ll change it back”
He typed away and then pointed the scanner at Jillian and pressed the switch. He repeated it with his Mom.
Both women were once again frozen. Matt typed in the reversal code and hit enter. Janet shuddered as she moved and Jillian lurched forward.
“There, it’s undone” he said.
“It better be you little brat!” Janet said slapping her hand back over her mouth.
Jillian’s eyes went wide and her eyebrows went up “I don’t think that was it”
“But I put in the reversal code” Matt replied. He rechecked his screen and ran back. Then he felt heat run over his forehead and his stomach dropped out.
“What is it? I know that face and it’s not good” Jillian said.
“What did you do doofus?!” Janet said still trying to stop herself from saying anything mean to her son. “I mean honey!”
Janet blinked feeling something inside her change “I think it worked! My whole thinking on you changed!”
“And mine too” Jillian said “I’m back to thinking that you’re the biggest jerk in the world”
“Why do you look so scared?” Janet asked.
“Um…I…” Matt stuttered looking desperately at both of them standing before him “Well the reversal code worked” he said flatly as he looked down at his screen “The problem is that it worked”
“What are you…?” Jillian said coming over.
Matt pointed to the screen.
‘Projection processing…58%...67%...’
“What’s it doing Matt?!” Jillian said in an angry but worried voice.
Janet now came over and looked at the screen ‘…93%...98%...99%...100% Projection complete. Commencing reversal’
The scanner turned on and sent a red flash of light out which washed over both Janet and Jillian.
They looked at each other as the screen changed to a split screen of the two of them ‘Preview?’
Jillian hit the ok button below Preview and her jaw dropped as she watched the images on screen change.
She felt warm all over that quickly changed to a sickly heat as she watched herself on the screen begin to shrink and thicken and change into her Mom all the while on the other side of the screen, Janet changed into Jillian.
“You…what does this mean? You have to stop this Matthew!” Janet said as Jillian just stood in shock.
“I can’t. Once the reversal code was put in, it locked into place. I can’t override it. I put it in the wrong field…I’m sorry”
“What do you mean?” Jillian said taking a step back, her foot thickening as it hit the ground.
“You two are being reversed with each other. You two are swapping bodies”
Jillian’s right foot shrank down two sizes but widened at the same time. Her toes shrank down smaller, her nails shifted and changed shape atop her changing toes. Her left foot was still in motion. Her toes pressed down, her heel up as it too began to change. She felt a cramp in her left toes and she looked down gasping as she saw them changing before her eyes.
“AH!” she screamed in horror as her hands went to her face “I don’t want to be Mom!”
“Don’t…don’t panic Jillian…I’m sure it’s not permanent. We just have to swap and then you can reverse it then right?” Janet said as she felt her feet begin to stretch out against the cold tile of the basement floor.
“Um yeah” Matt said very unsure it was true “It has to reset. I can’t do anything until this is finished”
“Well I know you’re very smart honey…you’ll get us through this” Janet said sneaking a peek at her feet. They were long and narrow with long toes topped off by bright white nail polish. Stark contrast to what she was used to and what she saw on Jillian’s legs now. Plain nails atop chubby feet.
Matt looked at his screen where it simply looped his Mom and sister changing places; essentially switching sides on his computer screen. Jillian on the right side becoming his Mom while on the left side, everything reversed and made his Mom into his sister.
Numbers ran above them as they did swapping vitals from the obvious of height, weight and age to heart rate and numbers that literally controlled every system in their bodies.
Jillian jumped; her body jerking as she began to shrink. 8 inches shorter awaited her “I was sooooo happy when I outgrew you and got taller, it was like, a major accomplishment!” Jillian whined stomping her heavy foot.
Her ankles thickened as her claves did as well. Dense muscles formed pushing her calves from long and sleek to short and stocky as she began to lose height.
Janet’s skirt began to lift as she began to grow. Her heavy legs began to trim and thin as her skirt lifted up exposing her knees. Her calves lengthened as they shaped up as well to youthful thinness.
“Oh…Oh!” Janet said as the cuffs of her blouse slid back up her arms. She looked at her daughter who was shrinking down before her. The difference in their heights was less and nearing being equal. Jillian shifted downward, the top of her head just barely above her Mom’s.
Jillian’s thighs bulged from beneath her short shorts. The bottoms strained as her flesh expanded. She lost muscle and gained fat as her thighs came together and began to rub even as they continued getting larger forcing her shorts up and in. The fact that she was shorter did nothing to help her clothing as her hips and ass began to spread out and grow.
Janet felt her legs separate underneath her skirt. The constant feeling of her inner thighs touching was no longer there as muscle replaced fat and her things thinned and trimmed growing long and lean in the process.
Matt could only look on in wonder as his Mom and sister matched up evenly in height. The two realized it as well. Their eyes met and their jaws dropped “Nooooooo” Jillian whined again as she felt herself drop even shorter and now found herself looking up a full inch to her Mother again.
“We’re going to fix this…” Janet said again shaking her head “This is only temporary honey”
Jillian nodded feeling her shorts stretch to their limits as her hips shifted even further. Her panties slipped up into her ass cheeks as they gained more and more mass. Her formerly pert and perfectly round rear was now full and sagging; cellulite dimples marked the backs of her thighs.
An inch quickly became two and then four as they continued changing bodies.
Janet’s skirt nearly fell off as weight slipped away from her to Jillian. Her hips narrowed, her waist contracted and her ass tightened and shrank down considerably into the pert and perky rear of her 16 year old daughter. “AH!” it was her time to let out a scream to acknowledge her changing body.
Looking down at Jillian who continued to change and fatten up as she received the body that had been hers, she saw Jillian’s waist creep outward and her stomach, exposed in her cream colored crop top begin to soften and puff out as well.
“Matt! Jesus Christ can’t you do something to stop this?!” Jillian yelled from a much less commanding position having to look way up to her 6’2” brother.
Matt could only scan the data running over his screen “No…I can’t override…it says you two are 52% swapped”
“So I’m more Mom than me?!” Jillian replied surprised.
“Um…yes. On a physical scale, you two have truly reversed; you’re more the other than yourself” Matt said. The images still looped and the numbers still changed, ticking off not only inches and pounds but years as well.
“Am I older?” Jillian asked.
Matt just stared.
“You are so fucking dead for doing this to me. For making me turn into Mom!” Jillian yelled.
Jillian felt a distinct pull between her legs. Her chubby knees buckled as her pussy fattened. She could feel hair poking through her skin, the sensations were so intense as her clitoris shifted, her skin folds changed shape and size and her body took on the very essence of Janet.
Jillian’s hands dropped and pressed on her soft abdomen, pressing on the very uterus that had carried her.
Janet staggered backward biting her lip “Oh my God” she breathlessly gasped. She had to use the back of a chair to remain standing as her body hummed and throbbed to life. Intense waves broke up and down her spine shivering out and down her arms and legs and up to the top of her head as her pubic area flattened and she went clean shaven. Her clit seemed so sensitive and so prominent as her skin shifted.
The two exchanged a glance as the waves subsided and they caught their breath.
Jillian rose up trying to stand as tall as she could and only managed to come up to her Mom’s chin.
“You look so tall Mom” she said “It’s like I’m a kid again in one way but yet not because I’m actually now older than you”
“It’s only for a bit Jill, we will reverse again and you’ll be back to being taller than me” Janet replied “But you really do look awfully short”
“Mom!” Jillian said with a tsk of disapproval.
“No! I just never saw it from this side…I knew how you looked to me at 5’ but being the tall one, it’s, well, really noticeable how short I am” Janet said.
“I don’t want to be short! I don’t want to be you! This never would have happened without him screwing around with his stupid inventions!” Jillian again turned her anger towards her brother.
As she did, she missed her belly pushing out. One second it was flat, the next, soft flesh popped out and drooped down.
Matt happened to be watching his sister’s weight number when it suddenly jumped 10 pounds.
Jillian looked down and saw her soft white belly fat exposed for all of them to see “It’s not my body, it’s not my body…I’ll get my own back…no need to…this is my Mom’s body…” she talked to herself as she reached up behind her back. A slight grimace on her face as she unhooked her bra just in time. She was feeling the pinch as her breasts began to fatten and grow.
Janet’s clothes just kept getting looser. Her panties were drooping off under her very loose skirt which finally gave up and fell off landing in a pile at her feet once her waist and stomach caved inward.
Janet gave an audible gasp as she felt it slip off. Her hands tried to grab it but instead simply went in and pressed down on her toned flat stomach. “I’m so tiny…I’ve never been built like this before” she said looking at her stomach moving her short white blouse out of her way.
Jillian simply glared.
Matt looked at his screen. Numbers were beginning to turn red. They had been running in black text but now, some system numbers changed text. He wasn’t even sure what he was looking at anymore. He was overwhelmed by the data. Once the numbers turned, they usually stabilized, running on a repeating pattern. The height numbers changed and locked in while weight and age still continued to fluctuate.
‘77%’ flashed on the screen and the image reloaded but this time it started out with Janet on the right and Jillian on the left.
Jillian’s chest and back widened. A few rolls appeared on her soft and short sides as her sleeves grew tight on her upper arms. Her breasts grew. They pushed her unhooked bra out and slid out from the bottoms as they sagged with more weight and gravity.
Janet’s long torso thinned even more as her shoulders pulled inward. Her breasts shrank up inside her too large cups, no longer even needing the support as they sat high and firm and much smaller and perkier on her chest. Her shirt fit her very poorly with the sleeves too short and the bottom continually lifting up.
“It has to be getting close to being done” Jillian said flexing her fingers as they now changed. Her fingers thickened and shrank back like her toes had. Her nails changed shape and went plain while she saw the bright white flash on her Mom’s hands “How is this even doing this? That cheap scanner and a laptop shouldn’t be able to do something like this!”
Janet nodded. Her long fingers wiggled a bit loosening up as the skin on her hands tightened up. “It’s so strange but it’s obviously real…it’s happening to us”
Jillian’s neck and chin shifted. Excess skin filled in creating a double chin if she were to duck it at all while Janet’s lifted, tightened and thinned.
Moisture and elasticity bloomed in Janet’s face. Her skin began to glow with youthful radiance as lines simply vanished. The lines around her eyes and mouth quickly dispersed while the deeper ones in her forehead took a few more seconds but also disappeared.
Her lips plumped, her cheeks rose, her nose grew longer to fit her face as her eyes widened drastically changing her appearance. 44 turned 16 in a matter of moments. Even her ears lifted and shrank.
More and more numbers turned red and either stopped moving or went on a predictable loop ‘92%’ read the screen as Jillian’s face began to rapidly change in look as she aged.
Her chin and jaw softened as her skin thinned. Lines etched along her mouth and the corners of her eyes as deep lines ran across her forehead.
Her eyebrows thinned as her eyes narrowed and her nose shrank. Her cheeks softened and sank in as even her ears grew larger and longer. Her lips thinned and her teeth weakened as they darkened a shade and went crooked. Braces were no longer part of her past; Janet was benefitting from them now.
They watched each other’s hair begin to swap. Janet’s growing out long and thick and lightening to blonde as Jillian’s rose up thinning and going darker to a chestnut brown color with even a few grays intertwined in. It rose to her shoulder level and styled itself as her part shifted from the middle to the side.
Janet’s hair was long and wild and thick as could be, resting halfway down her back and cascading over her shoulders.
A tickle in her throat signaled that changes were still occurring and Janet was reluctant to hear but knew she had to say “Our voices…” in Jillian’s youthful sounding higher voice.
“Oh Jesus” Jillian said in a deep, more mature voice “Has your stupid program stopped yet?”
“Um…” Matt could feel the hairs on the back of his neck rising up as 98% changed to 99%. “Almost…you’re at 99% and it’s slowing down” The images were no longer looping; Janet stood on the right while Jillian stood on the left.
Janet had to step out of her discarded skirt to take a step forward. She cautiously began to walk towards the computer, her body feeling so light and airy.
Jillian hung back still; watching her own body move around independent of her was freaking her out.
Matt watched the screen and his heart jumped when it hit ‘100%’
A new message appeared ‘Process complete…subjects have reversed completely…do you wish to continue’
He hit ‘OK’ and the computer began to run again at its faster rate. Numbers began to run across the top of the screen.
“What’s it doing now?” Janet asked hovering.
“I think it should be resetting. It might, um, it might take a bit” Matt said swallowing hard.
“Ok…just let it do its thing for now” Janet said. “Jill…maybe we should change into some of each other’s clothes for the time being”
“But I don’t…fine…these are pinching me like crazy” Jillian admitted.
The two of them walked to the laundry room where Janet took off her panties and blouse and bra. Jillian had picked up the skirt on her way. “I need your help” Jillian said. She put her arms up and Janet had to tug the crop top off and both needed to pull as Jillian shimmied to get the shorts off.
Jillian dressed in her Mom’s clothes and Janet found some folded up laundry to put on; panties and a bra, a pair of black leggings and a simple gray top.
When they walked out, Matt did a double take “You two…you look like…”
“Each other?” Jillian said looking up over a foot at her brother.
“Well yeah”
“So where are we?” Janet asked.
“Um…I’ve got some good news and some bad news” Matt admitted.
“What’s the good news?” Jillian asked.
“The good news is that I think you two will be able to switch back” Matt said.
“And the bad news?” Jillian added.
“It’s going to take a week to reset”
Jillian’s mouth dropped.
“The other good news would be that you two can now swap back and forth whenever you would want but it would be on a week scale. You would have to spend at least one week as each other before swapping back”
“Okay” Janet said. She could tell Jillian was furious “Jill this could be worse. You could be me permanently”
“Guess you’re going to end up understanding each other just like I set out to show you” Matt said.
“Shut up” Jillian replied.
