"So what brings you two in to Other Side VR today?" Thomas asked the two people sitting across from him, his 9 o'clock appointment. 
"Well it's a long standing discussion that we've always had that has...evolved haha over the years" the man said as the woman laughed and crossed her legs.
"It's about my husband" she said
"My best friend" the man added.
"We want to see the other side of him" the woman said "I want to see what he and his friends talk about...I want to experience that bond which is something I've never had"
"And, I'll admit I'm curious enough to see what her relationship is with him. I want to see a totally different side of Steve"
"Well if you're going to become his wife for a week in the program, you will" Thomas replied with a chuckle. 
"I know it's odd but I'm secure enough haha. I'm genuinely curious to see how Diane sees him"
"And I want to see Steve through Dave's eyes. I think I'll understand him better" Diane said.
"And is Steve okay with this?" Thomas asked.
"Yes" they replied in unison. 
"Then let's go ahead and get started" Thomas said. 
Thomas went through his standard spiel about acting naturally and keeping the harness and cameras and microphone on at all times.
"I'm really just realizing how different everything is going to look just being you in here" Diane said as they got suited up.
"Oh absolutely. I'm not only going to be female, I'm going to be over a foot shorter haha" Dave said.
"You’re going to be me...a Mom, a nurse. I know you want to see how our marriage works but you're going to be in for a week" Diane added.
"Yeah and you get to experience my marriage too. And my kids and my teaching job. Steve might become a very small part of this VR thing" Dave reminded her.
Dave and Diane got along well for being in competition with each other.
Dave and Steve had been friends since the 6th grade. They grew up together, played High School football, shared a crappy apartment together through college and were still best friends. 
Diane had first met both of them in college and had been at that nasty apartment.
Now they were all in their early 40s. Diane was actually the oldest of the three of them having just turned 44. She was 6 months older than her husband and 9 months older than Dave.
They looked at each other differently though as they suited up for their week of recording.
Dave was in the best shape of them. At 6'4 and 210 pounds he coached football as part of his teaching duties and worked out regularly. Short brown hair and brown eyes with a full but well trimmed beard "it's going to be quite different being in such a different body from my own" she thought. She gave a quick shudder thinking about it. But that shudder also contained a hint of excitement "what if we really can feel what each other feels...I am going to have a dick. I might get to have sex as a man" she thought.
But of course that just got her mind flowing the opposite direction "he could experience sex as me! I'm going to absolutely make sure we do it this week haha. Let him see how he likes it on his back with Steve inside him"
Dave was also examining Diane in a new light.
Diane was 5'2 and 150 pounds with hazel eyes and shoulder length curly/wavy brown hair. She had the quintessential Mom Bod. 
Thick thighs and a slight belly held her extra weight along with her 38D breasts. "I'm going to have the Mom bod!" Dave thought. "That’s going to be me. I'm going to look in a mirror and see her face. I'm going to look down and see her body like it's my own. My hands...they'll be her hands. I'll shower that body with them. I know she's going to have sex with Steve" Dave shuddered slightly as a chill went up his spine. "Am I that curious?"
They shared a smirk as they left.
For the next week, they all did their best to ignore the rather elaborate harnesses and rigs Other Side had developed over time.
They had evolved over their time to make the experience even more immersive. They could now register and recreate smells and almost every feeling. If a subject touched a hot pan, the wearer would feel a burn. And yes, it was very popular to pay someone to switch just to experience different types of sex.
It was common enough to see people walking around in the rigs that it didn't raise eyebrows anymore.
Both Dave and Diane made sure to pack in their week, almost like a competition. 
Dave's wife Abby was also a close friend to Steve and Diane. A few years younger, she had missed the college years but once she found out, she was definitely up to giving Diane an experience to remember.
A week later, they met up in the parking lot
"Long time no see Mr. Dave" Diane laughed as she pulled up next to his car. "Oh...just wait until you get to live my life for a week"
Dave smirked watching her get out. He had never noticed the way her feet dangled and her need to really step down to get out of her SUV.
"I could say the same thing" Dave replied adding a low chuckle "Get ready"
"Oh I am...I was born ready" Diane added as they walked in together.
They turned in their equipment and waited. 
With the enhanced features, it now took over a month before the program was ready but it was worth it.
They scheduled their time off and arranged for their swap.
Dave admitted to his wife that he was a bit nervous as his wife drove him to the facility.
Steve drove Diane. He wanted to watch the beginning of it while Abby didn't want to see.
"Just let me know when it's all over and I need to pick you up" Abby said as they stood in the lobby.
Diane and Steve passed her on their way in and her way out. 
"Wow...you are in for quite a trip haha!" Abby said to Diane adding a knowing look.
"I think your husband is going to come back singing Man I Feel Like A Woman to you" Diane teased.
"I'm curious to see how both of you come out of this" Abby remarked on her way to her car "Have fun" she added with a wave.
"That’s your wife for the next week" Steve said.
"Yep.. but I get to be like almost a whole foot taller than her for a change"
"You get to be a whole lot more than that to her and with her" Steve added.
Diane blushed and punched her husband in the upper arm.
"Seriously, I really hope you have a good time doing this. I want you to enjoy yourself and go as deep into this as you can. Get into it" Steve said.
"I'm planning on it! I'm hoping this is as awesome as everybody says it is and it lives up to the hype" Diane replied.
Dave stood by the side door talking to Thomas. His eyes flicked that way and Thomas saw Diane and Steve walking over and he gave them a warm smile, walked over and shook their hands as he greeted them.
After some basic small talk, "Are we ready to get started?"
Diane nodded, looked around nervously and said "Ready as I'll ever be"
"Yes" Dave said simply.
Two technicians came out and took them back to separate rooms to start hooking everything up to them. WiFi hookups connected, they were fitted with their harnesses and headsets.
"Step into the first room please" the technician said, sweeping an arm toward the open door. "You will get acclimated there and receive your next directions"
The harness weighed a few pounds and it took Diane a moment to get used to it and comfortable in it. 
She stepped through the door and into a large well lit room. One wall of which was a giant mirror. 
She saw herself reflected back. She didn't see the headset, just her own face. She was dressed in the outfit she had worn in all those weeks ago; just a pair of denim shorts and a black v-neck top. "So…" she said as played a bit for the mirror.
"Welcome Diane" an overhead voice boomed out and she jumped, grabbing her heart.
"Welcome Diane...or, should I say Dave since that's who you'll be for the upcoming week"
Diane gave a little laugh "Yeah I guess so...I guess I'm going to have to get used to responding to that name"
"But to live like Dave, you need to look like Dave" Diane's harness heated up as it kicked into high gear.
"Diane Laura Atkins…" Diane could feel her heartbeat picking up. Her whole body tingled and she felt warm "...I think David Jacob Smith sounds much better for you. So much more fitting...very suitable. You will now change into David, leaving your Diane self behind. Fully understand what is happening to you...you and David will switch bodies and lives and live as the other...you will become the other"
Diane shivered just hearing the overhead voice echo through her, driving home the reality of this virtual reality.
Diane turned toward the mirror and cocked her head slightly. She could feel something. Something was happening to her body.
Little muscle twitches were popping. One along her right side, another behind her left shoulder. It felt like something big was building up across her back. 
Diane held her shoulders in and tight. Just then her calf muscles clenched, her thighs strained. She felt like she was growing. 
"Am I?" She asked the empty room, her voice surprised sounding and higher than normal.
She looked at her reflection and her jaw dropped. She was absolutely growing.
Her legs were stretching out longer and bigger. Her chest was expanding, her arms growing longer as Dave's height transferred to her body. No longer short, inches were piling up as she grew taller and taller.
"Haha! This feels great!" She called out, putting her arms out wide, watching herself get bigger in the mirror.
"Oh...what if…" she looked down and let our a hearty laugh "HaHaaaaaa!" She laughed as she watched her feet and the ground sliding further away.
"Oh my gosh this is so realistic!" She said as her body expanded. Weight and muscles spread her out even more as the 5'2" woman now gave a projected height of 6'4". What was more was that she believed that she was 6'4" now.
"I can actually feel this! I feel like I'm really turning into Dave...like my body is changing as I stand here...this is so cool!"
Diane looked down and lifted her toes. They were tingling and twitching. "Are those...are those Dave's feet?! Haha! They are!" She was fascinated watching her toes grow longer and wider. Her feet themselves pulsate growing outward, larger. 
Diane could see details there. Her feet look manly. Blocky and wide, a man's size 12.
Hair began to appear on her legs. Coarse black hair poking through her skin as her legs now began to change shape.
Already longer, her muscles stretched out. She saw that her legs were losing smooth curves and gaining muscle instead. Sharper cuts along her calves. Her soft thighs hardened with masculine muscle mass.
"I don't believe it...they even feel differently under my hands" Diane said, gripping her thigh with both hands, swearing it no longer felt the same to her.
She looked in the mirror and watched her tight and high cut denim shorts change into a pair of khaki cargo shorts. 
Her hips slipped inward and she felt her ass tightening as it shrank down ridiculously flat.
"Holy shit, I lost my ass! I've got a flat guy ass!...this is oh…"
Her jaw dropped again as she felt pressure and a stirring in her pubic area.
"How are you doing this? That feels so…" she squished up her face and shivered. As she gyrated she felt something distinctly drop out of her.
"Oh God. Oh My God...I've got a…" her hand went between her legs and she felt it. "Oh my God...those are balls! And...holy shit! It's going up! I've got a freaking erection! I felt it one way and now it feels different. It's tingling and standing up and I can feel the pressure of it against my shorts!"
Outside, in a room just on the other side of the wall, Steve stood in shocked amazement watching and listening to his wife.
"Absolutely incredible" he said watching his wife grab what she thought was her dick and squeeze it like it's hard.
"Isn't it though...the sensations we can recreate and simulate"
"I can’t believe how convinced she is"
"The sights of it combined with the sensations makes it real. As the week goes on, she'll think and act more and more like Dave. Getting more of his impulses and thought patterns...thinking things through as him"
"And he'll do the same as her," Steve said.
"Correct. The computers have a base program to run and it combines things that they did that week but it can also anticipate where they are going by the end and react to the individuals taking some autonomy over what they now consider their body and life"
"That’s amazing" Steve said. "But they can still only do things that the original did in that week?"
"Correct" Thomas said. "Like, Dave can't smoke in her body unless she smoked while wearing the rig"
"Gotcha" Steve said. To him, his short little wife was in a bare room just freaking out, but on the monitor, he saw that she had Dave's bottom half and her own top half that even looked differently because it was stretched out taller.
Diane finally put her hands on her hips and just stared down at the bulge in her pants. "I'm a man" she said while still looking over her large breasts. "I've got...his...his parts" she added.
Her soft stomach, a bit larger than she liked, a bit noticeable in certain outfits, began to ripple.
Diane lifted up her shirt. Faintly just at her waistline, she saw her C-section scar. It faded.
Her stomach firmed up. It was longer than before, shaped differently and hair encircled her navel. "I am learning details about Dave that I never thought I would know"
She felt a tightness in her chest, a pressure, a squeezing. 
Diane dropped her chin to her chest tightly as her breasts began to shrink. Dropping a cup size quickly, she distinctly felt her breasts come away from the cups of her bra. "How did they do that?" She thought frantically as they continued diminishing in size. The mass of them disappearing steadily. 
She pulled her shirt out and watched them swindle down to her size as a 12 year old and then, with an almost audible pip, they were gone.
Just a flat chest sat there. Diane let out an exasperated "ah" before her chest stirred.
Now pectoral muscles built up. Hair began emerging out around her small nipples and then across the middle. 
Her bra vanished instantly and her shirt changed from a black v-neck women's cut top into a simple plain black tee.
A surge of energy and strength now hit her chest "Ur…" she let out as back and shoulder muscles tightened and twitched, firming up and forming a very masculine physique.
Her soft and full upper arms now popped with biceps and triceps.
More hair formed on her forearms and her wrists thickened.
As a nurse, Diane kept her hands polish free and they were frankly kind of rough, but they were still feminine. Her nails had the more oval shape of most women. Now, her fingers thickened and grew longer, larger. Her knuckles became more prominent and her nails flattened out.
Her hands were masculine now too.
Turning to the mirror, only her face and head remained her own.
"Oh this should be good" Steve said as his wife's hands probed around her soft cheeks not feeling the headset at all.
Diane's long hair began to shorten. She felt it tugging against her scalp. Her hands went to it, she could feel the strands pulling through her fingers.
In a matter of seconds, she had the short hair that Dave had.
"I can’t feel my hair" she said as she patted her short hair in the mirror and tugged on the front ones "Well I mean I can feel it but it doesn't feel like my hair" she said only to be answered this time by the overhead voice "Because it's no longer your old, long hair. Your hair is short now Dave. You're almost to your complete and proper look"
Diane's face began to twitch. Muscles were triggered by the program. She spread her mouth wide.
As she did, her neck elongated and an Adam's Apple popped out.
She stared at the mirror as her face seemed to evenly flow in a changing pattern.
"I never thought I'd see my wife turn into my best friend...the detail of it. The meticulous detail of it amazed Steve. He was able to pull up a close up of the mirror detail on the monitor. His wife's face was there framed up.
In the next room, Diane leaned up as close as she could get, she stared.
Her small nose began to grow larger. Her jaw dropped but her jaw was strengthened. Her chin came forward.
"So how does it feel to watch her become him" Thomas asked.
"It's the fact that both faces are so familiar to me. I grew up with Dave...I have known him for over 30 years.
Her lips changed, her teeth, her tongue and she examined them all, moving every muscle in her face. She clacked her teeth together, surprised at how big they were now.
"What the Hell…" she said, surprising herself so much she jumped back.
She looked shocked. Her cheeks were reforming up stronger but the sound of her voice had made her jump.
"My voice…" she said
Steve looked at Thomas.
"We change their microphones so yes, they speak with the other's voice. When Dave walks in, he'll hear her sounding just like him."
Diane's ears grew larger, she could see them clearly no longer covered by hair. Her eyes changed size, shape and color and her vision changed.
Her forehead, eyebrows, eyelashes all changed then, she felt facial hair starting to grow.
It tickled like crazy as it grew in. Hair on her upper lip, cheeks and chin. She put her hand up and rubbed her beard.
"I have my own beard" she said, touching her facial hair.
"She loves beards and facial hair...it’s the only reason I have one" Steve told Thomas. "I wonder if she's getting another erection?"
Thomas chuckled "Well get ready because Dave is ready to come in"
The technician took his time getting Dave hooked up. The computers behind them were whirring and revving up and down as he got into his harness and headset.
Finally, the door slid open and Dave walked in.
"What the…?" Was his first reaction. His heart rate instantly jumped.
He saw double, triple...at first he thought he saw Diane standing there waiting for him but in the blink of an eye, it was him standing there. "A reflection" he thought.
Dave stepped in and the reflection didn't match his movement. Then he saw his reflection on his right as the room he was in had one while wall as a mirror.
The other Dave crossed his arms over his chest, set his stance, and gave a smug smile.
"What…?" He said drawn out, his brain catching up.
Diane saw his confusion then a bit of recognition and she nodded as he finally said "D...Diane?! Is that you?"
"Yep...all 6'4" of me! Haha! I'm you!" Diane's low voice rumbled out.
"Holy shit...you even sound like me...you look, exactly, like me" Dave was almost tiptoeing up to his doppelganger.
"Wild right?!" Diane agreed.
Dave swung his head around, with the mirror, there were 4 of him in the room. "I'm, uh, guessing you have, um, all of my body"
"Every last detail" Diane confirmed.
Dave's eyes dropped to the front of Diane's shorts as his jaw dropped.
"Welcome Dave" the voice boomed out overhead and they both looked up.
"Very good...but only one of you is really Dave now"
Dave felt warm, he was blushing and he could just feel Diane's smile.
"Now, we reverse your roles and your lives and your positions with each other. You originally saw your best friend's wife but now, you see his best friend there. That is because his wife has turned into you David and so, you get to turn into Steve's wife. You will be Diane. You will look and act and think like exactly like her. You will be the wife now"
Dave swallowed hard "When you put it like that…"
"David Jacob Smith; become Diane Laura Atkins...your true name, your true body" the voice boomed out.
Dave felt warm all over, his harness sending out sensations as the program kicked in. Little muscle twitches started popping out all over his body.
With a little hiccup, he felt his shoulders shrug and his hips bounce and settle. "Something happened" he thought. He looked over and saw his own face looking shocked. Diane chuckled, waiting for Dave to realize what was going on.
"Wait…" Dave said slowly as he realized he was looking up into his face "How did you…?" He turned to the mirror and saw the top of his head was lower than the top of, well, his other head.
"I already grew...it’s time for you to shrink" Diane said.
And with those words, Dave felt his whole body begin to pull in on itself. Muscles constricting, his entire body felt like it was pressing in. His stomach flipped like he was going down a hill on a roller coaster.
His jaw hung open as he steadily got shorter and shorter.
He was down to Diane's chin level before he knew it.
She gave him a little wave goodbye sarcastically just using her fingers.
"How is this happening? It's a program, I get it but it feels so real"
"It's cool right? I loved the feeling of growing" Diane admitted. 
Dave's body was tingling all over as he continued to shrink. He looked up at Diane, over at his reflection, which was dwindling down, and down to the floor, which was rising up and getting closer for him.
"Yeah...it does feel, well, pretty good but…"
"But you're not used to having to look up to anyone, let alone me. Albeit in your own body, but, it's not going to BE...your body. You're about to be short little Diane. You'll get used to looking up to a lot of people from now on...Me and Steve chief among them" Diane rubbed it in a bit.
"Ohhhh, burn haha" Steve said. As he watched, he saw his short wife looking down in her headset while a foot away, giant Dave stood looking up in his. His head tilted back more and more. "When we first started dating, Dave constantly picked on her for being short. She's loving this"
Dave looked down, he thought his body was looking softer, different from usual as he shrank down a full 14 inches in height.
His bare feet looked so close, his legs looked so short.
He snapped his head back up and discovered he was at Diane's armpit level. He was mid-chest to her.
The reflection to his right confirmed it; they had switched heights. Their massive height difference had been reversed. And if that was possible, everything else was too.
"Whoa" was all he managed to say as he gave a full body shiver.
"A bit intimidating isn't it?" Diane asked with a casual shrug.
Dave gave a weak nod.
He had gotten smaller all around. His weight and proportions had altered as well.
His clothes looked big and baggy on him. He started looking over his shoulder at his loose shorts.
Dave's toes began to twitch and tingle. 
Their programs ran in tandem and as Dave looked down at his feet, Diane's gaze went there as well. "It started with my feet too"
"Ah!" Dave let out a gasped exclamation as he felt his feet start to move on their own. He watched as the shrank and narrowed. His toes shrank down much, much smaller. His nails rounded and shrink to fit her tiny toes.
"Dave loves his wife's nails painted. It's killing him that my wife's are plain" Steve said.
"I..I've got your feet!" Dave lifted his toes and moved them about, spreading them as far as they could go, which wasn't as wide as he had been able to do with his own toes "they're so small...so...feminine"
"Haha...just wait until you get the whole feminine package" Diane said. Shecwas really enjoying watching Dave's changes in front of her. She was tingling for real now.
The hairs on Dave's legs began to thin and vanish. His skin went completely smooth.
He dropped his hands and ran them over his shins "I don't feel any hair! My legs are smooth, it feels like just shaved them"
Diane laughed "Well I had just shaved them and you'll do it again this week"
Dave looked up surprised. He felt twitches on his calves. He spread his feet to get a better look as his calf muscles smoothed out,  rounding off instead of remaining boxy.
Looking at the mirror gave him a different perspective of his now obviously curved and female lower legs which now complemented his small feet.
His knees gave a quick wobble and the reflection shimmered as they changed.
His compact thighs now began to spread out softer and wider. His slim male deltoids changed to give him the full thighs of a mature woman.
"I called them thunder thighs...but Steve loves them" Diane said as she watched his legs turn into her legs. "They look exactly like mine...but they are Allllllllllll yours!"
Dave blushed watching the changes moved up underneath his baggy shorts. As his hips, ass, and waist all started to move, his shorts changed in a pop that happened in the blink of an eye.
"Ah!" He jumped seeing tighter more form fit denim shorts hugging his smooth, thick thighs.
He could feel panties underneath them now. His underwear had gotten tight, and he had an undeniable bulge in the front of these high cut shorts.
His hips spread out, his ass grew fuller and rounder. Still in great shape for 44, her ass was shapely but definitely larger than his own. 
Dave felt his center of gravity change as he gained womanly hips and a woman's rear end.
His waist began to shift and slide but that was the least of his troubles at the moment. 
Dave was feeling a very intense numbing sensation in his lower abdomen. 
"Oh...ohhhhhhhh….Dude haha!" Diane said his discomfort and obvious embarrassment. 
"Not cool and not fair! You were by yourself…" Dave said. He wrenched his back and shoulders around trying to get a feel for what was about to happen. 
He felt a creeping sensation, shrinking, but on a different scale than earlier.
His eyes bulged as he realized his testicle had risen up to his pubic area.
Dave clenched his right butt cheek as a testicle popped up into his body, then he clenched the left as the other one went in the other side.
"Ohmygod….that was such a weird feeling…" he was panting.
His penis went numb. The bulge began to get smaller. His panties began to fit better as it shrank down smaller and smaller. 
He patted his front. He still hit the head of his penis and he shook all over. 
He shivered from head to toe "Oh GOD!" His voice lurching as to him, his penis vanished. But as it did, he felt everything else appear. He felt his skin slick with moisture as he gained a vagina, a vulva, and a clitoris. He felt changes inside of him. He could picture his uterus forming, fallopian tubes, ovaries...all of it.
"Oh shit…" he muttered and looked up. He unconsciously rubbed from his hips inward until he was pressing down exactly where a uterus would be.
"You okay over there….Ma'am?" Diane added with a chuckle. "Sucks to now be a daughter of Eve after spending 43 years never worrying about anything like that" she had a very satisfied look on her bearded face, almost talking down to him. "Changes everything…"
Dave gave a nod, a knowing nod "I am a woman...I've got all, um, all your parts"
"Not my boobs yet but...soon enough"
Getting smaller again, Dave felt his build changing. The entire structure of his torso flipped to female. 
His hips had come out and his waist had come in giving him the curves between them. His sides softened, his back shifted as muscle mass decreased and muscle function changed.
His stomach softened. The hair there vanished leaving more smooth skin and a smaller navel bur a small pooch of a belly topped off by a faint C-section scar.
New sensations built up in Dave's chest. His right shoulder popped forward, then his left.
A wave of pleasure broke out at each of his nipples as his chest hair disappeared along with his strong pecs.
Steve watched with interest as Dave's lower lip trembled. He stood still.
His chest jerked. He exhaled and closed his eyes as he felt buds form up; soft and yielding, they started to grow. 
Bigger unto cone shapes. Bigger into small globes, they briefly turned tear drop shape before regaining their roundness as the grew bigger still. 
"38Ds…" Diane confirmed. "And they're all yours"
Dave was blushing as he looked down. They looked and felt real to him.
Steve watched as his friend's hands moved around above his still very flat chest, gently squeezing and lifting them. He had to stifle a laugh.
"You haven't seen anything yet" Thomas informed him. "Just wait...as the week goes on, they get deep into it. Little mannerisms and personality quirks even transfer"
"Really?" Steve said changing his view to the monitor where Dave's arms now looked like they were changing, getting soft and full, losing his biceps and triceps.
Dave missed his forearms slimming and the hair there going very thin and light. It wasn't until his fingers tingled and twitched. 
"Oh" he let go of his breasts, feeling them drop, then suspend as Diane's bra appeared on his body.
He felt his breasts cupped and encased. His shirt now also changed from a baggy shapeless tee to a women's cut black v-neck top.
He could feel the bra, became aware of the straps digging into the tops of his shoulders and of the fabric wrapped around his chest and fastened across his back.
Holding up his hands, both of them got a good look at his fingers as they shrank down and slimmed, his flat nails lifting to slight ovals but cut short. His large and thick silver wedding band now flashed to gold and shrank down narrower. It was soon joined by a 1 carat diamond ring, Diane's engagement ring. 
"God I wish I could paint these...get a mani pedi"
"Don’t you dare waste my money on that!" Diane snapped as his palms shrank down.
Dave stuck his tongue out "Oh so now it's not my body…"
Diane mocked him playfully. "You have to do what I did...and I didn't paint my nails that week"
"What a shame" Dave said as his neck compacted and smoothed out in the front.
"You might want to watch this part closely in the mirror" Diane advised "Your um, your face is starting to change"
Dave whipped to the side to go face on to the mirror and got up as close as he could. 
Diane watched with interest as did Steve in the monitor.
"Aaaaa my hair!" Dave called out as his hair began to grow.
"Hair first" Diane confirmed. From her vantage point next to him and above him with her increased height, she saw it darken at the crown and begin to extend out growing longer. Waves and curls worked in along with her few grays. Just a smattering right now, but they were there.
Dave put his hands up and grabbed the growing strands, elongation under and through his fingers. He could honestly feel it growing.
He felt the hair tugging at his scalp as he pulled the now shoulder length hair in his hands. "How…?"
He blinked as his face began to move and shift. His chin pulled back and rounded, his jaw weakened but now looked more appropriately feminine.
His lips shifted as his whole mouth shrank down smaller. His teeth got smaller too but were strong, straight and white and he clacked them, baring them to see before running his tongue over them testing their surfaces.
His beard and facial hair began to thin and fade away, pulling in and vanishing leaving him with a smooth upper lip, cheeks and chin.
Dave watched in awe. His lips changed shape and softened, his nose shrank down to button cute as his cheeks rose up higher and rounder filling out his face.
His brown eyes flecked with gold changing to hazel and shrinking down, setting in differently.
Dave's ears shrank. Double piercings appeared on his small lobes followed by two pairs of gold hoops.
His forehead shifted, his eyebrows narrowed and trimmed and he batted his eyes as his lashes thickened. 
"Unbelievable" he muttered softly but he jumped.
"Oh!" Diane added as she caught it too.
Dave reared up and back, his hand going to his throat.
"I heard that…" Diane teased.
"Yeah, so did I," Dave said, hearing Diane's voice coming from him.
Diane had a deep voice for a woman but it was still higher to Dave. 
The tingling started to dim and the warmth passed too.
Steve still marveled watching them act like their bodies had physically changed while he still saw the truth; Dave still towered over Diane, both were still the same they had always been but in their minds and in the program, they had switched places.
Dave shivered all over "Oh my God" he said, still adjusting to the sound of his voice. The thing was, he no longer questioned Diane's voice.
"Huh...look at us and the tables have turned" Diane said.
"I don't know what I thought, but this is absolutely more" Dave said "It's so realistic"
"I know" Diane put her arm out. In the program, she rested it on top of his head playfully.
They both felt it and saw it happen to them. 
Dave glanced at their reflections and he shook his head.
"Diane" the voice boomed and Dave looked up.
"Very good...you've accepted who you are already. You are to leave through the door on the left"
The door Diane had come in through slid open. "I'll see you around" was all he said as he walked past her with a knowing smile. 
Steve watched him go. He was swaying his hips more as he walked, he was walking like his wife.
"David...please exit to the right"
Diane took longer strides, walking differently as well.
"Unbelievable" Steve said
"So now they go in and begin to recreate each other's life" Thomas said as he flipped monitors over to different cameras. Both looked like they were driving, which made sense.
Steve tried to remember all the things he knew about, the things he had done with both of them that week. "I think this is going to be overwhelming" he admitted. 
"Not necessarily" Thomas said shaking his head "you can see that they're both adapting extremely fast to their new situations. That will only get stronger as time goes on. They will be so immersed that it will be natural for them"
"But afterwards...I'm honestly thinking about Dave once this is over. We will have had sex with each other!" Steve said.
Thomas laughed "Everyone worries about that. I haven't had any fallout from it though. You have your sign in so you can watch whenever you want?"
Steve said yes.
"You can also come in at any time and watch in here. Technicians will be monitoring them 24/7" 
Steve looked over and saw Dave walking with a purse slung over his shoulder, putting it down, kicking off shoes and curling up very Diane like on a sofa. He took out Diane's phone and began scrolling.
Diane looked like she was mowing the grass.
Dave went along with several mundane things that passed a Saturday afternoon just working around the house. Steve was there, their two kids came and went giving him an odd motherly feeling.
It was nothing he had ever felt before with his own kids. His were younger by several years but that had nothing to do with this, he just felt different and he realized he was acting and reacting like a Mother and not a Father. 
"This body gave birth to those two" he thought.
His body gave a little jerk; just a little shoulders back and stomach forward roll and he coughed to clear his throat.
Dave let his mind wander...volleyball. High school volleyball came to mind. He let it roll. Number 30...his number, volleyball shoes, knee pads, elbow pads sliding on, smooth legs, smaller than his current ones "of course I only weighed 120 in high school"
Other sights filtered in; a silent bus ride after a bad loss, the bus full of girls. A sleepover with most of those girls watching horror movies. Shortest girl on the team.
"I knew she played volleyball but had I heard about all those other things" he thought, feeling the need to use the bathroom.
He walked down the hall and went in, the mirror didn't lie "that's me" he stopped and looked. "She wouldn't have posed like this" he thought as he messed with his long hair. As a test, he lifted his shirt and shimmied his shoulders to shake his boobs in the bra. Dave laughed "so I have some freedom in here...huh" 
"I'm going to drop Tyler off at Johnny's house and Brooke is going out with her friends...I made reservations at Beau's" Steve told him.
"Beau's...I have to get dressed up!" He realized it was a setup. "Of course she'd do this"
Looking back in the mirror, he felt Diane there, could hear her in his mind teasing him "Yep...you know I hate wearing makeup and usually only do it maybe twice a year but for you...you need to do this" and he heard her familiar laugh in his head..
