"Welcome Elizabeth and Callie" The overhead voice rang out. "Your time in the program has come to an end"
They both felt their bodies begin to twitch and tingle and they turned and faced each "Oh...it’s...you're...I'm…" Callie put her hands out and watched as they shrank down and slimmed. She turned them over and back. Just beyond she picked up her Mom growing and examining herself as she changed back into herself.
Callie's focus went to her Mom. Liz's hair was darker and her face was rapidly aging. She lost the innocent look and Callie's heart broke seeing it.
She watched her body expand and she passed her up in height as her legs regained their curve and heft.
Liz was watching her own changes, staring down at herself. Her breasts grew and steadily filled her vision even as she watched the floor get steadily farther away as her legs stretched and she regained height.
Liz's bodysuit had released all the pressure points that made her feel like she was Callie. Her aches and pains returned as her perspective changed. Even the clothes she was wearing changed.
Callie's own suit was doing the opposite. Pressure points engaged to make her simulate shrinking. Her energy returned as the little aches and pains she had gotten used to vanished.
She watched her own chest recede. Her legs slim and her curves disappear. 
Shocked looks sat on both of their faces as they evaluated the other "Mom?" Callie said in her own high pitched voice. The voice modulators had been turned off.
"Cuh...Callie?" Liz said
"Wow...this is weirder than when we first switched" Callie nervously laughed.
"Um yeah haha...I agree...I guess I wasn't ready, I uh…" Liz said before drifting off. Something still wasn't right. Out of the corner of her right eye, something caught her attention. She turned her head and laughed "Oh my gosh Callie...look at our reflection! They haven't changed yet!" Liz called out excitedly.
Liz turned to the reflection and laughed as she put an arm out, then a leg and made a face controlling the small girl in the mirror.
Callie jumped at first seeing the reflection in the mirror tower over her. She smirked knowingly as she turned to face it head on. 
Callie put her hands up and splayed out her fingers watching her Liz reflection do the same.
In the control room Thimas cocked his head. The display screen for 35C read Elizabeth Ann Lange 09/03/79 and it started blinking.
He looked to 35D; Callie Alana Lange 04/11/10 and it too was blinking.
He squinted as Alana rolled back

Liz blinked and shivered. She giggled seeing her small Callie self do the same.
Callie stepped up to the mirror. She put her right hand up and with her heart pounding went to put it flat against the mirror.
Callie's hand drew nearer. She expected to feel cold hard glass. Instead she gasped as she felt a tickle of static electricity and her hand simply passed through.
But in passing through Callie saw something else that froze her.
Upon hitting the barrier, her hand grew. Her fingers shot out longer and thicker. Her nails grew thicker and oval shaped.
More lines and rougher skin, veins on the back of her hand. She recognized it instantly.
"MOM!" She yelled out. Her face was an astonished profile in shock and joy and wonder and possibilities.
"What...oh my GGGGOOOODDDD! Callie is that...is that what I think it is…"
Callie nodded and bit her lip to hold back her emotions. She wanted to cry.
"That’s my hand! On...on the other side we're still each other!"
Callie nodded vigorously "Mmmhmm"
She held her hand on the other side. Even her wrist looked like her Mom's up to the point where her arm cut through the barrier.

"If you want to...we could see what happens on the other side" Callie said. "A world where I really am your Mom and you really are my daughter"
Liz paused "I can’t take away your youth! That wouldn't be fair"
Callie shook her head "Don’t worry about that! I'd be taking away your age! Your education...your experience...I'd be sending you back to have to grow up all over again"
"And you say that like it's a bad thing!" Liz replied.

Liz defiantly shoved her right hand out towards the barrier. She felt the tickle as the glove on her bodysuit constricted down, this time actually, physically shrinking her hand down to child sized.
They both saw Liz's hand change into Callie's as it passed through the barrier.
Her fingers slimmed and shrank. Her nails bounced as they turned tiny and her smooth youthful skin gleamed.
Callie took a deep breath "I'm willing if you are but we have to agree"
Liz nodded enthusiastically "I want this more than anything"
"Oh God me too!" Callie replied so relieved.
"I honestly didn't want to go back" Liz said

Liz lifted her right foot and put it to the barrier.
Below her she saw her bare foot. Size 7 ½ with the marks of 42 years of wear and tear. Her oval nails. They wiggled ever so slightly as she held her foot suspended in the air.
Just beyond though, hovering as well and right to the barrier was a much younger looking foot. So much smaller with tiny toes and flat nails, pink, supple skin with no damaging marks.
Eliz Alana Lange 04/11/10
Eli Alana Lange 04/11/10
Her right big toe buzzed as it touched the barrier. The reflection blurred out until they could both only see Liz's foot pushing through.
Her toes contracted and shot inward, shrinking down as they passed through. Liz giggled...it tickled as she moved her foot through. 
Her foot narrowed, her arch rose, her skin healed and her heel popped inward.
Liz's mouth formed an O as her foot turned into Callie's foot. 
It was much smaller; probably only ⅔ the size it used to be.
In the actual room, Liz's bodysuit clenched down squeezing her foot into the different shape it was now reading as the correct size and shape for 35C.
Liz put that foot down laughing as her ankle changed along with half of her right calf. She scooted forward until her whole calf changed. 
"Oh my God…" Callie said as Liz just nodded triumphantly.
Callie spread out the fingers on her left hand as she moved it to the barrier. Her hand hitched as it received the static shock then it bloomed, growing bigger, fingers changing shape, nails morphing.
In the actual room, Callie's bodysuit stretched to accommodate her bigger hands. Sensors engaged as 35D's hands set at their proper size.
Callie lifted her right foot as Liz splayed out the fingers on her left hand. "3...2...1" Callie counted down. Liz smirked and put her hand through.
As her bodysuit constricted shrinking her hand and rejuvenating the skin and nails inside, the two of them watched Liz's hand change into Callie's small hand. 
Both had matching sets, both had each other's hands.
Liz flicked her skinny fingers three times out from her palm just slowly shaking her head in awe. "How is this real?" She asked.
Callie lifted her petite foot and held it up much like her Mom had. They took in the contrast between the two and Callie giggled as her toes breached the barrier.
Instantly her toes bulged outward. The nails popped up as the rose into oval shapes upon wider toes with rougher skin.
Her foot continued widening and growing as it moved forward. Her arch dropped lower as age and wear appeared. Veins appeared on top. Her ankle swelled as it too now passed through.

Callie's heel thickened, her skin lost its softness as it came in contact with the floor again, this time on the other side. Now a size 7 ½. Now Liz's foot. Her foot, her control.
Thomas put his hand to his temple and he pressed down. He had zoomed the camera in and he watched as Callie's small foot encased in a trademark blue bodysuit bloomed larger.
E Ann Lange 09/03/79
Computers whizzed, more computers went online reading the data, preventing an overload.
They looked at each other. Both partially suspended through the barrier and they knew what the other was thinking. "Are you ready to…?" Callie cocked her head toward the barrier and nodded.
The reflections had distorted as they had gotten closer and breached it. The heads of the reflections angled up or down; the features a mixture of both of them.

Liz nodded. The grin on her face and the eagerness in her eyes displaying a childlike glee.
C Alana Lange 04/11/10
Thomas pulled in a deep breath as he watched the computer loads.
Liz took a deep breath and held it. Her forehead approached the barrier and she felt sparks, an electric tickle building up. "HHHNNNN" She let out a high hum involuntarily.
Liz's forehead broke through. Wrinkles vanished as her entire skull vibrated. Her head was physically getting smaller. 
Her eyebrows lightened and lost their sculpted look even though thinner. They looked wilder.
Thoughts exploded. Stars and lights danced in her eyes like walking directly out of a movie theater into a July afternoon.
Her eyelashes thinned. Her big brown eyes narrowed and shrank down turning green as her vision sharpened.
The slight bags under her eyes vanished. The laugh lines at the corners of her eyes disappeared.
Her hair began to lighten and thin atop her contracting skull. 
Thomas watched closely as the face visor and headpiece shuddered. He saw her whole head shrink down but all the detail was lost under the cowl but he knew a woman had just become a child.
Liz's eyes began to blink and flutter as her nose shrank down drastically. She felt her nostrils decrease in size. The tickle caused her nose to crinkle up as it changed shape and changed into Callie's. 
Liz's cheeks lifted up higher and rounder, her ears began to shrink as her hair continued changing. 
The space between her lip and nose popped.
Her lips thinned and went numb. She felt teeth shifting in her gums which felt way too willing to let her teeth move apart.
Her tongue slipped and as she pushed farther forward, she heard the humming sound double in intensity. Out of the corner of her eye, she saw Callie break through.
"HHHHOOOONNNN" A sound like bad guitar feedback looped around them. The computers kicked into maximum power. An entire auxiliary bank whirled into life as Callie, just a moment after her Mom, pressed her forehead up to and then through the static barrier.
"Mmmmmmmmmmmmm" Callie hummed in her girlish high pitched voice as the tingling intensified. Then, she was going through. She exhaled through her nose as her forehead breached. Age lines etched in. Her forehead widened and spread as her skull expanded. She got a piercing squeeze in her ears but only for a ping as her eyebrows darkened and sculpted.
"Hrrrrnnngg" her hum turned more determined as she pressed on. Her hair began to darken and change.
Again Thomas saw the face shield and visor shudder and the headpiece expand out like a balloon getting a sudden puff of air.
Callie's eyelashes thickened. Her small green eyes now grew large and doe like as they turned deep, dark brown. 
Her eyes itched. Her eye muscles twitched as her vision weakened. Slight bags puffed out beneath her eyes and laugh lines etched in at the corners.
The bridge of her nose exploded outward, increasing in size. Her nostrils flared as they too grew. The end of her nose broadened and pushed out, dominating her new face.
The little space between her nose and lip shrank down as her cheeks slimmed and drew out longer and sleeker. Her ears grew.
Callie's lips plumped and her teeth slid through liquid gums to straighten and fill out strong and in line.
Lines came in at the corners of her mouth.
Callie's eyes fluttered open instantly, aware of the nose in her view.
Liz's mouth tightened "CALLLLLIIIIMMMOOOMMMMYYYYY!!!!!"
Liz called out, surprising both of them. Her voice began as a woman's voice but began to rise in pitch until a girl's high pitched sound emerged and finished off her cry.
Liz's chin pulled back and up and in along with her jaw and her neck and throat.
Callie, just emerging, shook out her dark auburn brown hair and turned her gaze to her right. Inexplicably yet entirely expected, she saw the young girl looking at her hopefully.
"MMMMUUUUCALLIE!" Callie swallowed hard on her word as her chin and jaw shifted as she spike. Her voice started as a girlish squeak that dropped a full octave in the course of a word. Her throat expanding, her vocal chords maturing and changing into Liz's as she passed through.
Thomas heard them

Liz's shoulders now hit the barrier and they shot inward, rounding off and beginning to drop her height.
Her forearms were through. They had gradually moved through along with her leaning forward but now her chest closed in.
Liz's nipples perked up as they reached the precipice and the static electricity zapped them.
Callie's shoulders passed through and widened. She put her arms out straight to gain her Mom's fuller upper arms.
The bodysuit began to stretch out over Callie's back as her height started to increase but it also began to adjust on the front side. 
The fabric loosened up as her flat chest hit the barrier.

Callie shivered as breasts began to form up and grow. Starting out small but forced to grow fast to keep up with her body which was being carried forward by momentum, mass built up rapidly and two perfectly round globes bounced into place, immediately caught by the suit.
Liz's chest deflated just as fast. Her breasts shrank down, mass dispersing and vanishing by the millisecond. In the blink of an eye, they were gone. 
Liz rocked forward. Her upper arms slimmed, her whole body slimmed losing weight and mass. Her right knee came through shrinking down.
Her thigh began to slim. Her stomach pulled taut with youthful skinniness.
Liz's bodysuit now corrected her torso size and height. The suit constricted and Liz's spine compacted. Her height dropped below 5 feet.
More of Callie's right leg pushed through. Her back continued stretching her out taller. Her stomach loosened and drooped. She had her Mom bod. The softness of the 42 year old she now was.
An awkward clench and an intense hot flash rushed through both of them as puberty and womanhood transferred.
Liz's hips narrowed as she inched farther forward. Her ass went flat, losing all mass and curve as she went further through

35C...90% restored…
Callie shivered as her hips spread shifting her center of gravity; she almost tumbled the rest of the way through.
Suddenly, she had an ass. A full heart shaped ass of a mature woman sprang out as her right thigh grew passing through.
Her left foot lifted. Liz's left foot came up as well.
The top of their left thighs hit the barrier
Elizabe Ann Lange 09/03/79
Elizabet Ann Lange 09/03/79
Callie felt the size of her thighs double. Full and firm, the curves hit her as fat and muscle increased. She glanced sideways to see her Mom almost all the way through too.
Liz's thighs halved. They went from her usual full thighs to skinny little kid legs; coltish and gangly.
More height transferred between them.
Callie noted how much shorter her Mom was than her now.
Left knees came through. Left calves came through. The static was jumping now, breaking up and crackling behind them.
Liz dropped her chin and looked over her left shoulder. Her big foot still remained but her ankle just slimmed down. Then a full spark ran through her as the top of her left foot hit the barrier.
Down it shrank. Several sizes just vanished in a shimmer. Small toes and flat, tiny nails atop them. Flat soft pink surface, then she felt a tickle in her left heel and then it ran over the sole of her foot. 
Liz hopped and put her left foot down flat as she curled up into a ball.
Callie trained her look over her left shoulder. Her tiny little girl foot remained. The barrier was breaking up. Wider and thicker bands sparked and jumped as her ankle puffed up. The top of her left foot hit the barrier flat and her whole foot wavered.
She felt it though. She knew it worked even as it came into focus. Longer toes. Oval shaped nails. Rougher skin, a few more prominent veins. She felt a sharp tingle in her heel that then ran down over the sole of her foot.
Callie exhaled and shivered.
The feel and sound of the room changed. A power down sound "WWWHHHOOOMMM"
Thomas looked at the room. Two people covered head to toe in blue bodysuits stood there. The smaller one on the right curled up, coiled like a spring; the bigger one on the left stood taller and began to feel around the top of her head.

'35C and 35D program restored 100% Back up initiated...backup complete'
Callie couldn't really see anything. A milky shield covered her face and distorted her vision. She began to feel around for the strap around her head.
She found it popped the snap and buckle.
Real light streamed in and blinded her. She blinked and dropped the mask at her side. 
Things started to come into focus. A very bare room with cinderblock walls. 
A slight wave of dizziness and vertigo "Did that really happen?" Her panicked mind scrambled for answers.
"Am I...is she...did we…? Was it just the end of the program or did we actually switch bodies?"
Callie's hands went to her chest.
Elizabeth was frozen, holding her breath. She swallowed and exhaled "Does that feel any different?" She thought remaining bent over at the waist. Her senses were off and returning to her slowly. Her awareness of her surroundings was not sharp. Her ears were ringing and she couldn't see. 
Liz's hands came up to her face and hit her visor and face shield "The VR mask...of course" she reached up and fumbled with the snap and buckle, her fingers were tight in the gloves of the bodysuit. The tightness of the suit became apparent to Liz. It clung to her but nothing felt out of place.
With the buckle undone, the mask slipped off and clattered to the floor. Liz focused on the ground and her feet encased in the blue booties came into focus "Did we just...Am I...am I Callie now? Is she me...was that real or part of the program?" Liz's scrambled mind searched for answers. Slowly she rose up, straightening out her back. 
Liz couldn't see Callie. She had turned the wrong way and her back was to her but she could hear her shuffling and moving. 
Liz put her fingers to her forehead and she found the edge of the hood that covered her head and she pulled it back. 
Liz felt cooler as her hair and head came out. She shook her hair out and froze again. 
Callie's hands came up, she hesitated just a split second, curious as to what she would feel. Her hands came to rest on her chest. "Ah!" She thought as she froze.
Liz's fingers grabbed a strand of her hair. She pulled it out and around for her to see "Ah!"
"Boobs!"
"Light!" Liz froze seeing the strand of light reddish blonde hair.
Callie's hands squeezed her full breasts. Her heart took off pounding, all the consequences of her decision were coming to her. "I have boobs which means we actually switched places! A million to 1 chance happened to us!" Callie thought as she spun on her heel to her right. 
Her back was to her but Callie immediately realized their size difference. She was much bigger than the small skinny figure in blue a few feet away.
She recognized the light reddish blonde hair. She pulled her own hood back now and swiped a few strands of auburn brown hair forward into her field of view "What should I say? What should I call her to get her attention? Mom...Liz?...Callie?"
Liz let go of her hair and touched her face. Her nose caught her attention "Small!" She thought as her eyes shot down. Now the floor looked closer. Now the front of her body looked flatter. She spun around.
Callie gasped and froze as Liz spun and faced her.
They came face to face and their shock was so immense. 
Liz slowly raised her chin up, her small mouth hung open as she looked up and up until she locked eyes.
Callie was looking down, nearly a foot down, her mind and mouth couldn't coordinate. Her mouth went up and down. 
Liz's mind took in everything she was seeing. There, right in front of her, stood her body. She examined her face, everything was there. Her eyes now worked down, bigger than her now, broader, a woman's body; a word came to mind "Mom?!"
Hearing that sweet high voice really in person brought tears to her eyes. Callie nodded and bent her knee and Liz rushed into her arms and they hugged.
Callie held Liz for a full minute. She stroked her hair and just soaked it in. "I can’t believe we really swapped!" Callie said.
The door opened and technicians came in, flanking Thomas in the middle. "Ms. Lange"
"Yes" they said in unison.
The technicians started undoing the bodysuits; undoing the wiring.
Callie exhaled feeling her suit release. Everything moved a bit freer. The back of her suit was unzipped and they undid her gloves. 
Callie peeled the gloves off and chuckled seeing her big hands.
The techs worked their way down undoing the battery pack, and undoing the zipper around her midsection, then down her thighs unhooked sensors until they finally undid her booties.
Callie shook it out as the techs started undoing Liz's outfit.
"So Thomas, what do we do now?" Callie asked.
Thomas cleared his throat "After you two get changed and are ready, I will meet with you to go over the next steps, the possibilities and the resources available to you"
Callie nodded. She realized that she wasn't wearing a bra and wanted a bit of privacy. 
As Liz's bodysuit unzipped, Callie saw she had a sports bra that was now huge and useless on her.
"Of course all of the disclaimers and legal agreements that you signed beforehand did warn you of this possibility so…" Thomas was saying when Callie cut him off.
"Don’t worry about it, we knew and we're not going to sue you but we do need to get all of our identification in order"
"Of course" Thomas replied. He led them to a suite where outfits were laid out in two separate rooms with bathrooms and full showers.
Neither had showered for a week but not yet. The door closed and they laughed. Callie peeled off her top "Holy shit haha...look at these! They’re real! Wooooo hahaha" 
"They’re yours!!!!" Liz added. She was taking her top off "And I've got nothing" she mocked making a frowny face and lifting her shoulders and dropping them moving that useless sports bra.
"Hips...ass...big thighs…I'm a woman!" Callie said squirming and gyrating to get the skintight bodysuit off.
She almost lost her balance trying to do a move common for a kid pull impossible for her now as she tried to lift her right foot and leg up to pull the pants off.
Everything flopped and jiggled and she sat down hard stumbling to a footstool "Whoa haha! I'm not as flexible as I used to be" she realized as she took off her booties and pants.
Liz watched Callie in wonder. It was really hitting her just how colossal this change was. Their whole lives flipped. Their entire relationship was rewritten and reversed. Bodies physically exchanged, education transferred.
She had gotten undressed much easier and she looked down at her body; the body of a kid. She searched her mind and emotions and found so many mixed feelings and gaps.
They showered. Both taking a long time to wash off the grime of a week and to simply recharge under the hot water.
Liz was out and dressed in black leggings, a gray sweatshirt, socks and tennis shoes, lounging upside down on the couch, her long hair wet and air drying, dangling down as she contorted herself on a couch.
She heard footsteps and she flipped right-side up to see her Mom come in looking radiant. A wide smile, hair and makeup down, a form fit green top, tight jeans that accentuated her hips and brown leather boots that covered her calves. "Are you ready to conquer the world Baby Girl?"
"I'm ready if you're ready Mamasita!" She replied.
