"Welcome to Other Side VR...my name is Thomas" 

Elizabeth Lange put her hand out and they shook. "Nice to meet you Thomas. I'm Liz and this is my daughter Callie"

"So honored to meet both of you" Thomas replied, shaking Callie's hand too.

Liz shifted in her seat and crossed her legs as she smiled politely as Thomas took his seat. Callie scooted forward in her chair until her feet finally touched the ground.

"So I see we have a request for what I call the Freaky Friday special" Thomas laughed. 

Liz nodded knowingly "Yeah I guess you could call it that but it's a mutual decision. We're both genuinely curious enough to see what the other one sees"

Callie nodded enthusiastically.

"And since it's going through a program, I know I can control what I do, so therefore, I know what she's going through when she's pretending to be me" Liz added. 

"Oh of course. This is quite a popular program...Mother and daughter that is. We've had a lot at a lot of different ages go through this" Thomas said casually. "We'll get you all set up for the recording and go over all the basics, you'll have your week and then once we get everything back, we'll get you scheduled for your experience time"

Callie was smiling "Awesome! I can't wait to do this" she said. 

The two of them went through the orientation and got their harnesses and cameras along with battery packs and sensory mounts. "I thought this would be heavier" Callie remarked.

"Yeah, me too honestly. You see people walking around with these but I've seen kids younger than you, a lot younger than you wearing them"

"5 is as young as we'll do" the technician wiring them up mentioned.

"Oh haha, if this works out I can swap a week  with your little sister" Liz laughed thinking of her other daughter Olivia who was 6.

"Oh now that would be really funny" Callie agreed.

Their week recording passed quickly. When Liz had to break up fights between Olivia and Callie, she wondered what it was going to be like on the other end of this. 

Making them dinner, getting them ready...everything that made her a Mom would be Callie's role. She would be the kid. Would she truly feel what Callie felt? A bit of guilt, some anger, frustration. Would she feel powerless having so much out of her hands and controlled by someone else? Had she forgotten what it was like to be a kid?

And would Callie really feel what she felt. The disappointment, the frustration,  the exhaustion. "Guess we'll have to see" she told herself. 

They waited several weeks before they could get in to actually run the program. Olivia would be spending the time with her Grandparents while Liz and Callie underwent the immersive program.

Different rigs; full bodysuits were given to them this time along with headsets. They were separated as the technicians got them ready.

Liz stood in the dark really after getting the outfit on. She could hear things, mechanical things whirring to life around her. Then, she saw a door slide open.

Liz stepped through and into a very sterile and well lit room. "Oh. Oh wow" she said, seeing how big it looked. The wall to her left was one giant mirror. 

"Oh" she jumped a bit seeing her own reflection.  It was her but not as she realized she wasn't wearing the bodysuit or harness.. she had a clear vision of herself standing in a pair of shorts, sandals and a green top; the clothes she had been wearing the day they started their recording. She could also see her whole face and her auburn brown hair. 

"This must be the start of the program" she said to herself.

She jumped as a voice came from overhead "Welcome Elizabeth"

"Oh jeez! You scared me" she laughed nervously at her overreacting.

"A childish reaction but that's to be expected from someone who is a child…"

Liz looked around.

"Or from someone willing to become a child. You are to switch places with your own 11 year old daughter. From now on you will be the child in your relationship with her. She will become the adult as you assume the body and life of a young girl. You cede your power and authority, your age and experience, your knowledge and control, your body, your name, your life...to her"

Liz swallowed hard hearing the voice.

"So welcome Callie Alana Lange. No longer Elizabeth Ann...no longer born on September 3rd 1979...now your birthday moves to April, 11th 2010. Your age, your height, your body, your mind...all smaller. Younger...to be Callie you must look like Callie. Welcome to your life Callie Lange"

The bodysuit began to squeeze down making Liz think and feel like she was getting smaller. All the visual clues expressed by the program reinforced it. To Liz, it looked and felt like she was shrinking; shrinking down smaller in size and younger in appearances.

"What’s that? What's going on? Why do I feel tight" she said looking to the mirror.

Her jaw dropped in shock "I'm…! I'm turning into Callie!" She laughed nervously seeing her reflection beginning to change. She looked down and saw that view was also changing. "Wow...this is amazing. It really looks and feels like I'm turning into Callie"

The suit restricted her chest and looking down, Liz watched her breasts shrink down smaller and smaller. 

She felt twitches in her legs and arms, her feet and hands. Itchy and tingling,she brought her hands up and watched in fascination as her hands shrank down. "Oh my Gosh...they're so tiny! But so smooth...they even feel smoother" she remarked as she ran her hands together over and back.

Liz's eye trained back and she watched her arms thin down.

Liz wasn't a big woman; just 5'4" and 120 pounds but a mature body of 42 regressing back to childhood showed massive differences.

She was shrinking down to just 4'5": Callie was on the small side; no real development yet but it would be coming soon.

Liz grabbed for her shorts as her thighs shrank down, thinning and losing mass and curve.

She could feel her shorts droop as her ass and hips shot inward before watching them change size and style into Callie's clothes. 

Her feet twitched and began to shrink down too.

Her toes pulled back. Her nails thinned and flattened atop them as her feet narrowed as they grew smaller but like her hands, they were getting very soft and pink "Young. I'm getting younger...my skin should be fresh" Liz reminded herself.

As her chest continued to constrict, she could see and feel her breasts diminishing until there was simply nothing left. Liz had gone flat.

Her hair itched and her face began to tingle.

She focused on the mirror as her body was very much Callie's but her face was still quite her own.

Her features began to soften and regress. Her hair thinned and lightened to a reddish blonde as it grew longer and straighter.

Her nose pulled back dramatically. Liz had a large nose but Callie's was button small.

That change, changed her entire look. 

Her lips thinned, her chin and jaw softened and her cheeks rose up high and round. 

Liz had large, striking brown eyes that now shrank down and lightened to more hazel in color.

She bared her teeth and gasped seeing Callie's crooked and oversized teeth in her mouth. She needed braces but had to wait until her final set of molars came in. She was simply not old enough yet.

Liz's wrinkles smoothed out of her supple skin as her eyebrows lightened but grew unruly. Her forehead and hairline shifted and she jumped again realizing that she had changed into Callie.

"Oh my GOSH!" She yelled out and jumped again at hearing her own voice. 

"That’s not my voice!" She yelped hearing the childish voice emanating from her

"I even SOUND like Callie!?" She laughed Callie's laugh "Well duh! Only makes sense but this is amazing! It's so immersive! I really get it...I sound and look exactly like Callie. I guess for all intents and purposes, I actually am Callie"

As she looked down and at the mirror, a door opened across the way.

"Callie?" Liz called out seeing her doppelganger step into the room.

To Callie, the door opened and she stepped through. The well lit room made her blink and she saw a small girl across the way. She stopped. 

Callie looked to her right and saw herself in mirror but it wasn't quite her. She was dressed and looked normal, she couldn't see all the equipment she had on.

Callie walked toward the girl "Who are you and why do you look like me?"

"Callie! It's me! It's Mom! They just...I mean the program...whatever! It's me!"

"Mom!? How?! You…" she rushed forward until she was standing right in front of her. 

They both saw quadruple with the reflections. 

Callie was amazed "It's perfect...you look and sound just like me!"

Liz nodded excitedly, "I know!"

They both jumped at the booming voice "Welcome Callie"

They both looked up and around.

"But...only one of you can be Callie from now on. One of you needs to be the adult; the responsible one, the mature one. Callie, your Mother has relinquished her body, her age, her experience, her life.

It will now become yours. 

Callie will be Elizabeth. Elizabeth has already become Callie.

Your roles will be reversed. Your body will become that of a woman. Your mind, your life will become Liz's. You will be the one who calls the shots. The adult...your birthday is no longer just 11 years prior but instead 42 years ago"

Callie was smiling broadly. She had put her chin up and out and her shoulders back standing straighter as she listened. She looked at her Mom and could feel the power shift between them. The other Callie's smile faltered a bit, she felt diminished as the actual Callie prepared for what was to come.

"You are no longer Callie Alana Lange. But instead, you are now Elizabeth Ann Lange"

Callie felt various muscles start to twitch.

"As she has gone backwards, you will go forward. She has gotten smaller and younger, you will grow larger and older. Assume the mantle of Mom. Take what is available to you...complete the process. Switch places with Elizabeth. Become Elizabeth"

Callie looked down a bit confused. She saw herself; she was wearing just simple blue shorts, a pink top and basic sandals. Her typical body; so plain and small, she couldn't wait to grow up, to see anything different. She had just been biding her time but now, she was excited to spend some time as her Mother.

The twitching increased. She could see her calf muscles moving, visibly bouncing: And then they began to stretch out longer.

"Ahhhh!" Callie gasped feeling and seeing her legs grow and change.

She looked over at her Mom and her eyes widened seeing that she was already taller than her. "Mom!" She said, astonished.

"Cuh...Callie!" Liz replied in a shaky and fascinated voice. Wonder sat on the young face as she watched her daughter begin to grow. "You...you're bigger than me" 

Liz now felt warmth in her cheeks and a burning on the back of her neck; a distinct feeling of embarrassment, a shift in power already.

Callie smirked, "Yeah. Yes I am bigger than you" Pride swelled in her, something else mixing in; power, authority.

Callie felt her feet spreading. She looked down and watched her narrow little kid feet widen and grow larger.

Her toes elongated, her heels thickened as her arches rose. The skin looked rougher, her nails looked thicker and more oval shaped; she had her Mom's feet.

She spread out her toes and lifted them wiggling them "They feel different, they move differently"

The tingling went to Callie's hands and those too grew larger from the palms outward working down longer and thicker fingers.

Her forearms lengthened. Her upper arms filled out, changing shape dramatically. 

Callie's thighs bloomed. From skinny little kid legs to full on mature womanly thighs.

They widened, rounded, and filled out full of curve and suppleness. They pushed her ass and hips, waist and midsection all out.

Suddenly, Callie's clothes grew super tight but then, they all changed. 

Her feet had grown out crushing her little sandals but now, she felt her feet encased in sandals that fit her feet perfectly. Her shorts were now Liz's shorts; perfectly suited to fit her expanding body.

"Whoa...you look so…" Liz tried to talk out of pure nervousness as Callie changed so drastically in front of her. She felt she had to speak just so Callie wouldn't forget she even existed.

"Big?! Mature?! I know! Isn't it awesome?!" Callie replied.

Her chest was tingling like crazy.

The bodysuit was stimulating all kinds of sensations, none better than Callie's growing and changing chest.

She turned to profile in the mirror and her eyes shot between the side view and top view. 

Callie's stomach rumbled and rolled as it changed but she didn't care "I've finally got boobs" she laughed.

They popped out quite suddenly; small at first but growing steadily larger and rounder. Callie thought she could even hear them growing as they stretched out her tiny top.

She felt her shirt billow put as it changed into Liz's top and she gained her Mom's bra.

She felt it; she felt the straps digging in and catching her growing breasts.

The cups caught her boobs just as they were about to succumb to gravity. Callie laughed as her shoulders spread and pulled back.

The reflection in the mirror showed her impressive bust but also the absurdity of her very childish face atop her now mature body.

It also showed an 11 inch height difference between the two of them.

Liz just looked up; her neck craned all the way up, her mouth open, her stomach flipping as she processed the reversal of the two of them.

Callie gave her Mom a condescending smile as the tingling reached her face and her head itched. "How does it feel Mom? How do you like being the little one between us? I know I love being like this already. I can't even tell you how great this view is...never thought I'd ever see us like this. See you as me...see myself from the outside like this...through the eyes of an adult"

"It's weird...this is so weird" Liz said.

Callie's hair darkened and lifted, changing style in long waves as it turned auburn brown. 

Her face began to change and she spun to the mirror to watch it closely.

Her nose began to grow. All other changes resonated outward from that one.

The bridge widened, the tip flattened down and her nose pushed out bigger. Callie became very aware of it increasing in her vision. 

Her vision was changing. Her eyes grew larger and changed to a deep dark brown; very striking eyes. A few lines etched in at the corners as more worked along the corners of her mouth and across her widening forehead.

Her eyebrows darkened and sculpted. Her ears grew bigger and she felt a weight apply on them; hoop earrings appeared. Her Mom's hoop earrings, now her hoop earrings. 

Callie's cheeks streamlined and went from childish round ones to sleek mature ones.

Her chin and jaw strengthened. Her lips plumped and she smiled a smile of genuine happiness seeing straight teeth appear in that mirror.

"I'm you!" Callie jumped "Ohmygosh that scared me HaHA!" Her laugh went up upon hearing it and comprehending that her voice had even changed too.

Liz jumped hearing her voice and her laugh no longer belonging to her.

Callie posed. She put her long leg out "Wow haha...I can’t...AH! Callie laughed heartily "Ohhhhhhh…this is amazing" she cooed.

Liz couldn't find her words or her confidence to say anything. She stuttered and sputtered a few sounds "uh..nuh...nuh-uh"

The program hadn't started yet, Liz didn't know how to respond. But she simply felt diminished. Her whole identity had just been flipped.

"Wow! Just...wow!" Callie said "This is just crazy right?"

"Yeah! Absolutely crazy" Liz said as Callie nodded and smiled encouragingly 

"You found your voice! That's great honey!" Callie replied "I love hearing that sweet little voice of yours!" She leaned forward and put her hands on her knees.

"Don’t...are you making fun of me? Cause I'm just you, you know"

Callie laughed "Just having a bit of fun" she reached over and tousled Liz's hair before turning to the mirror. 

Callie started touching her face. "I can feel it. This nose! It feels so real! I had no idea how it would feel but now it's mine...I mean, it fits. This is my face haha!"

Callie tugged at her hair and touched all around her face and body "I have curves"

"You have my body!" Liz said loudly 

"And you have mine!" Callie replied looking at their new reflections. She put her arm around Liz and they both gasped as they pulled closer together. 

It really felt like Callie was taller. Liz felt her head top off hitting Callie on the shoulder and Callie felt the same. She simply knew her Mom's head was below her own; unable now to be above hers.

"You ready to be my baby girl?" Callie asked, using Liz's nickname for her.

"I guess so Mamasita" Liz replied with Callie's nickname for her.
