"Hey everybody and Welcome to a special episode of Cooper's World!" Tanner Schwartz said to the camera for his YouTube show.

Cooper was a 2 year old Golden Retriever and every week a new video went up on YouTube and Facebook and a few other platforms.

"This week we're going to dive into the world of VR...what does Cooper see?! What if one of us…" he looked and pointed and gestured at his girlfriend Chelsea "...got to live as Cooper for a whole week!"

Chelsea rolled her eyes, crossed her arms over her chest, stuck out her hip and looked annoyed but she still smiled.

"So we actually started this a few weeks ago so we're going to show you what happened then so you'll be caught up!"

Video started up at 'Other Side VR' Tanner and Chelsea stood with a young man while Cooper ran around sniffing everything.

"Hey guys this is Thomas! Thomas is going to be helping us out with this! So the goal here is to get Cooper fitted with a GoPro and harness so we can get his sights and sounds and who knows, maybe the smells too haha!"

"So we came up with this special harness and rig for Cooper" Thomas said "it'll record everything for a week and then we'll get it and edit it down, get some transitions and get it all set up"

"So Thomas...how about getting Chelsea and I set up too...maybe we'll do a future episode with the two of us" Tanner said.

On the video a disclaimer ran across the bottom on a scroll "I have no intention of doing a future episode of just us. Thomas and I discussed this earlier as a way to get Chelsea to wear a rig! I'm going to see if we can get Cooper to wear the Chelsea VR while she's wearing his!"

"Of course we can" Thomas responded.

"That's awesome! Thanks" Tanner said as Chelsea looked a bit surprised. 

It took some time to get Cooper settled down and used to wearing the harness and rig but eventually he did get used to it.

Chelsea and Tanner then took their turns getting hooked up and their instructions. "Just act naturally and interact like nothing is on you. I know it'll take a bit of time but with all three of you wearing them, it should be easier" Thomas added.

The video cut back.

"So yeah here we are" Tanner said "Now that was a few weeks ago and we just got word that Cooper's footage is ready to go so we're scheduled to go down and get Chelsea all set up...you excited Chels?"

"Yeah sure...let’s do this" Chelsea said giving a double thumbs up.

Chelsea Sanders was 5'4, blonde haired and blue eyed. Her nose was a little on the large side but she had an extremely cute smile. She was also in great shape and had a great body and she got plenty of attention from their subscribers. 

Tanner filmed them going in focusing on Chelsea's amazing ass in a pair of tight yoga pants as Cooper tugged on his leash dragging her along.

"This technology is going to blow your mind. It is the most immersive experience you can get. Chelsea; you’re going to absolutely feel like you're a dog" Thomas told her.

"I guess I'm going to find out" 

"The harness recreates feelings and impulses and instincts. You will be fully engaged and immersed as Cooper"

"And we can see all of this?" Tanner asked.

"You’re going to see exactly what she sees but it won't be in 1st person for you. But, you will also be able to see Chelsea in real time as she acts and interacts with the program and then we combine that to see Chelsea interacting and how that all translates together" 

Chelsea looked nervous but game.

"Let’s get this going!"

As two technicians hooked up Chelsea to her harness, headset and all the computers running everything, Tanner leaned over to Thomas "Is Chelsea's program ready for Cooper too?"

"Yes it is. Once we get her going, we will get him all set up"

"Well we will see if he goes along with it" Tanner replied.

"Oh I don't think it'll be a problem. Once we get him a few minutes in, he'll start to receive Chelsea's impulses and thoughts, her decision making...I'm curious but I think he'll want to continue. I think it's going to be a great show"

"Really?" Tanner was surprised, frankly a bit shocked "It's That Deep?! You're telling me that once inside the program, Cooper will, what, get Chelsea's brain waves?"

"In a way, yes. We will see if he gets her self-recognition. That is the essential part of getting two people to transfer and experience the essential part of this...Chelsea will definitely become Cooper. His dog instincts are some of the strongest I've ever seen. She's going to have the time of her life! It'll be like she's a dog and always has been. But for your dog...I think it'll work and it's going to be amazing to see how it'll go" Thomas said. 

"Wow...if you say so" Tanner said.

Chelsea was rigged up "I'm ready...I really hope you don't embarrass me with filming me"

"No babe...don’t worry...everything will be done with class haha" Tanner said.

Chelsea gave him a dirty look. 

Chelsea went into the next room. Cameras were set up. "Go ahead and put on your headset; your program will begin shortly" she heard overhead. "Enjoy your journey"

Chelsea gave a big but weary smile as she pulled down her headset.

Chelsea found herself standing in a much larger room with one whole wall as a mirror.

Chelsea saw herself but she wasn't wearing a headset or harness. It was just her in her tight yoga outfit.

"What’s she seeing?" Tanner asked.

"In the beginning, she just sees herself but she's about to see herself turn into her dog" Tanner said matter of factly. "We put in a full transformation scene that turns the person into who they're going to be"

"What?! Oh my God! Can we see that too?!" Tanner was jumping up and down in excitement.

"We sure can" Thomas replied.

"Oh this is going to be amazing" Tanner said.

Chelsea looked into the mirror as a voice came over. She shrugged her shoulders and cocked her head slightly as she got comfortable in her harness. "Welcome Chelsea...or, should I say Cooper since that's who you'll be for the upcoming week"

Chelsea 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 Cooper, you need to look like Cooper" Chelsea's harness heated up as it kicked into high gear.

Outside, they saw Chelsea jump and let out a little yelp as her hands went to her face. 

Her hands started up close to her headset but moved out a few inches as they explored. "She must be getting Cooper's muzzle" Tanner said. Chelsea used her pinky finger to lift at her lip and ran her tongue over her teeth.

Her hands went up to the top of her head and she was pinching air but stroking outward "And Cooper's ears too!"

Inside, Chelsea's jaw dropped as she watched the mirror "Oh my God!" She yelped as her face began to change.

Her nose turned black and flattened out just before she grew Cooper's muzzle.

Her nose, the whole front of her face pushed out as golden yellow fur grew out coating it.

Chelsea could feel it. It felt so realistic, so real as her lips thinned and her mouth elongated. 

She saw her teeth changing as her incisors turned to fangs and her front teeth shrank. She watched in awe as her mouth turned into a dog's mouth. 

Smells exploded in her senses. Suddenly, Chelsea could smell everything. Everything was magnified a thousand times over; it was overwhelming. 

Her tongue grew wide and long until it popped out of her muzzle and she began to pant.

Tanner and Thomas noticed her tongue hanging out as she pulled at her ears "She is really getting into it already! This is amazing!" Tanner mugged for the camera.

Chelsea felt her ears warm up. "Ah!" She managed to say without pulling her tongue in.

Her hands went up and massaged her growing ears as they shifted.

First, they lifted up higher on her head before growing larger. Sounds magnified as they first perked up with a thin coating of hair. Then, they flopped over as the fur really grew in.

Chelsea let out a very canine sounding whimper as her eyes shifted and turned a full uniform dark brown.

Her vision blurred and colors dulled as she now saw the world through dog eyes.

"My face!" She panicked "I have a dog face! I look like my dog!"

Tanner watched as her hands went all around her face and head. Then, she froze before she pulled her shoulders back and brought her elbows in tight to her sides. She put her hands up and flipped them back and forth several times before bringing her thumbs in tight.

"Oh...she must be getting doggy arms and paws!"

Chelsea looked over her goofy dog face with a stupid look on it. That happy Golden Retriever smile greeted her even without trying.

Chelsea felt her body move on its own. Her arms were shrinking "I'm getting doggy arms! And paws!" She realized.

It was very realistic to her. Her arms shrank down, fur appeared all over as her hands shrank down. She flipped her hands back and forth as she watched the fur travel down and cover her shrinking fingers.

They felt melded together and she brought her thumbs in tight as she watched them disappear into useless, to her, dew claws, sliding up her narrow front legs.

Tanner's jaw dropped as he watched his girlfriend refuse to use her full arms or hands, holding them tightly at her sides and using her hands like clumsy paws as she pet her own chest.

Chelsea's floof of fur came in on her chest and when she looked down, that was all she saw. No tight yoga top, no perfect 36D breasts, just a lot of growing fur.

Chelsea howled.

Tanner and Thomas were shocked "She’s reeeeeaaaaallly into this" Tanner said.

"I told you it was immersive on every level. It's like nothing created before" Thomas assured him. "She really thinks she's turning into a dog. Every visual cue is there along with enhanced senses...she's feeling warmer as her fur comes in. She'll act like Cooper. She's going to need her naps"

Chelsea spun as she felt her tail growing out.

Her harness engaged pressure at the base of her spine then released. It even created a breeze as she twitched her muscles swishing it as it grew.

Chelsea wouldn't use her arms but she growled as she spun watching a tail form up as a little nub before bursting out with dangling fur swishing about. She worked to control it and amazingly, she could.

"Ha!" She thought proud of herself as she felt her muscles control it and flick it how she wanted.

"Oh...oh gosh! What's she...she's going to all fours!" Tanner yelled as Chelsea arched her back and dropped onto her arms while slowly rising up on her toes mimicking a dog's stature as much as she could.

Chelsea, after getting her tail watched her fur spread over her belly before she felt her hips lock and shift throwing her down and forward.

"Shit! I just lost my ability to stand on two legs! I really am in a dog's body!"

To her, she watched her feet change much like her hands, narrowing down as claws and thick pads replaced her toes and nails.

Cooper had been fixed when he was just 6 months old so at least she didn't have to worry about that but, she still cocked her head down and saw that she now had a dog penis between her legs.

Chelsea barked at her reflection, now completely that of Cooper. She sat. 

To her, she was sitting just like a dog would but to her audience, she was on her butt with her legs swung to the side.

As Chelsea was adjusting, two technicians were getting Cooper ready in the next room.

It took some time and he resisted getting the headset on since it covered most of his head above his muzzle. For a while, they didn't think it was going to work but then, he settled down and sat and wagged his tail.

"Get him in there!" Tanner said as they opened the door. Cooper trotted into the first room.

To Cooper, he smelled his owner and saw her sitting on the ground. Then she got up on all fours and he was confused but thought she was playing a game with him so he ran over.

For Chelsea, she smelled another dog. Every sense told her another dog was coming in as soon as she heard the click of a door handle.

She saw her exact double coming towards her. Emotions flooded her "Dog! I'm the dog around here! Who is this dog?!" She stood up and watched him trot. When he broke into a run towards her she spun and met him so she could sniff him.

Tanner watched in awe as Chelsea acted just like a dog sniffing Cooper's butt while Cooper sniffed her.

Then, they played. Both yipped and snapped at each other in a playful way.  "This is amazing!"

Cooper suddenly sat back confused. He cocked his head as his Master shimmered as she sat. Then, Cooper saw a dog sitting in her place. He let out a concerned little growl as his program began. 

He barked at the new dog sitting next to him.

Chelsea backed up putting her tail down to show no aggression "No Cooper, it's me!" She tried to say but only low whines came out.

"Why can't I talk?! I can't override this somehow?!" She thought before thinking "Wait...why did they send the real Cooper in here anyway?"

The harness and headset began to whir into life, rushing all kinds of new thought patterns and impulses into Cooper.

"Cooper. Sit." Came a voice overhead. Both Chelsea and Cooper sat. 

"Good boys...but only one of you is really a dog now…only one of you is Cooper now" Cooper and Chelsea looked at each other. They both saw another dog looking back, tongue hanging out.

"Now, we reverse your roles and your lives and your positions with each other. You originally saw your female Master but now, you see a dog there. That is because your female Maater has turned into you Cooper and so, you get to turn into your female Master. You will be Chelsea. You will look and act and think like your Former Master. You will be the Master now"

Cooper's ears perked up as Chelsea hung her head and crouched down submissively.

Cooper's harness was running at high speed. The dog turned toward the mirror and saw his muzzle pull back. 

Cooper leapt up and let out a curious yip. He rubbed his muzzle against his upper arm, seriously confused. 

Smells diminished for him and he turned around but as he did, he stopped and now he stared at his reflection. He saw blue eyes and so many more colors and a lot clearer.

Thomas and Tanner were afraid he was going to tear off his mask and break the program but getting Chelsea's eyes had stopped him.

Cooper moved his mouth and the reflection smiled Chelsea's smile. More and more of his face changed as his fur receded.

Cooper's big floppy ears shrank down and his hearing faded to human levels. 

"Look at him!" Tanner said as he moved his paws rubbing the side of his head below his ears.

Cooper's fur changed up top until he simply had Chelsea's long blonde hair.

Chelsea cocked her head and sat up. She was fascinated by Cooper's changes "He looks like me! We're switching places! Cooper is going to be me during this. He must be running my program and they're turning my dog into me!" 

Her heart beat faster and she wagged her tail. She felt warm for many reasons...something about switching places with Cooper was more exciting than just acting like Cooper. Seeing him as her Master…interacting with him when he's in her body.

Cooper now put his paws out and turned them over and back. In the reflection and in what both Cooper and Chelsea were seeing, Cooper's front legs were turning into arms and his paws into hands.

Cooper stood in shock going back and forth from looking at his reflection to looking at Chelsea who now, he was looking down at.

As Cooper felt and saw his fur recede, his face showed shock as his mouth became a round O of surprise. 

The fur receded and then a new sensation hit him causing his pretty little face to blush.

Cooper felt his chest rising up and tingling in the best way possible. 

Chelsea's big, perfect breasts emerged and grew into big round globes on his narrowing and now smooth chest.

The harness tightened simulating a tight yoga top that now covered his chest except a line at the bottom where a flat, toned stomach peeked out.

The harness now caused a pulling sensation on Cooper's tail making him feel like it was pulling up inside his body.

He yipped at it and Chelsea started barking. To Chelsea, she had distinctly heard her own voice yell out "Hey! That's my tail!

Cooper heard it too.

To Thomas and Tanner watching outside the program, they heard Cooper making small grunting and growling noises with small whines and barks in between.

But inside the program, Cooper was now talking and Chelsea understood every word.

"Oh my gosh boy! I'm turning into you! I'm going to be human in here...isn't that amazing!" Cooper said.

"Yes! I can't believe this is possible but I love it!" Chelsea said only for both of them to hear <Bark...bark, bark, bark>

Cooper laughed "Wow I can't understand you anymore but I can tell you're happy and excited too, aren't you Coopie!"

<Bark!>

Chelsea was a bit frustrated. She wanted to say "Yes! I'm excited and I love it too" but only a bark had come out again as her tail wagged.

Cooper felt his hips pop and shift throwing him upward and forward. He felt weight coming onto his back side as he received Chelsea's firm, pert, and big perfect ass.

Cooper put his head over his shoulder and took it in. The reflection showed eyebrows going up in approval.

Both watched as Cooper's legs extended and plumped changing from a pair of dog hind legs into Chelsea's human legs; curved and firm. Chelsea looked to the ground as her dog's back paws widened and became her feet. She picked up the distinct smell of her Master as pads and claws turned to toes and painted nails.

Cooper was shocked. His old body was right there. Only coming up to his waist now and looking up at him for everything with dull dog  like simple senses. He felt different. 

Cooper's mind was racing like never before. Complex thoughts, emotions and words were pouring into him in a nonstop flood. In here he was human. In here, he was the Master. In here, their worlds were reversed and he was in charge. He was Chelsea. She was just Cooper.

A door opened to the right and the voice said "Go through and begin your adventure. This experience will truly change your life"

Cooper stood. As much as he could, he rose on his haunches and tried to walk like a person. He patted his thighs "Come on! Come on Coopie!"

Chelsea on all fours followed him as they exited.

Tanner mugged for the camera again. "Wow! I've never seen anything like that ever! That was absolutely amazing!"

"Now we let the program run for them. When it's all over, we'll bring you back in here. You'll get all the footage and you can watch the ending but for now, it gets boring for us as they'll interact in a small room that's ever changing with props and food. Whatever you did that week will be recreated for them"

"But this time with Cooper as Chelsea and Chelsea as Cooper.! So Chelsea will be jumping in the pool to swim and playing fetch and, well being a spaz like Cooper…" Tanner said.

"And Cooper will be getting dragged by Chelsea on the leash and basically catering to Chelsea's needs as she works"

Tanner laughed. "I can't wait for next week to see the ending! Till next time peeps!"

Thomas and Tanner stood talking and watching the monitors from inside the room. As best they could, Cooper was throwing a tennis ball and Chelsea was tearing after it, catching it in her mouth and trotting back with it.

Cooper was acting as if he had thumbs and full range of motion. To him, he did. He was also having a conversation with a computer generated Tanner.

Chelsea was having a great time running full speed using dog reflexes and muscles given to her by the program and the harness. And given to her by Cooper.

To her, it was a fair trade for the duration of their program. He got to experience what it’s like to be human and she got to experience what it was like to be fully canine.

The smells alone that she picked up on were enough to keep her busy. 

After a long time playing, Chelsea felt hungry. Not peckish, but full on starving and craving meat. A can of dog food sat on the counter and Cooper made his way to it. Just tapping it opened it but to him, he was using a can opener. The program was enhancing his motor skills to the point where he managed to get it into a bowl and onto the floor.

Chelsea bounded around excited and anticipating dinner and she dove into taking huge hunks into her mouth and swallowing them just like Cooper did when he ate.

Her harness and the program were amazing upping animal instincts and behaviors while dimming her humanity as much as possible.

"Pslsplslllllppslppslplllllppppssplsplspl" came the distinct sound of Chelsea drinking her water.

Cooper let Chelsea out and she dashed about. She smelled everything, chased squirrels, went to her favorite tree and lifted a leg. Then she saw the pool.

Everything in her said "go jump in and swim! It's your favorite thing to do!"

As Chelsea ran, she skidded to a stop feeling caught and ashamed. 

"Cooper! Stop right now! Don't you dare jump into that pool!" She heard her Master yell.

Chelsea looked and saw female Master standing in the door with her hands on her hips.

Female Master walked over to her fast, feet slapping the ground wagging a finger at her

"Bad dog…you know better than that!"

Chelsea felt fingers under her collar "Collar?! When did put on a collar?" She thought but allowed herself to be dragged back inside. 

Chelsea saw her doggy bed. She went to it, sniffed and walked in a circle three times before laying down in it. Soon enough, she was asleep and dreaming dog dreams.

Cooper was pleased with how everything was going. He was aware he was in a simulation that allowed him to feel, think, and look human. But it was more than that.

He truly felt human. "This feels...possible. like it could be a reality for us. An alternate universe…" Cooper's thoughts were progressing exponentially. And it was just on the first day.

It felt like Cooper was typing on the computer and on the phone, doing Chelsea's work and her side gig of running their various sites responding to fans and looking for sponsorships.

Cooper ate a salad, carefully constructed to be easy on his stomach, but to him, he was living and eating like Chelsea. 

He went through her routine of showering and cleaning herself as the program ran through all of this.

In the middle of the night, Chelsea woke up. She walked around the house checking out the perimeter, listening to noises and just generally sniffing. She saw the outline of Female Human Master in her bed asleep. She sniffed and put her nose up to a hand that was hanging loose.

Cooper, in his sleep felt a cold dog nose hit his small, delicate hand.

The program shot into hyperactive upon that seemingly innocent connection. 

It connected more sensory neurons, triggered a very human dream which brought even more emotions his way.

Chelsea completed her midnight stroll and went back to sleep on the floor.

Chelsea woke up needing to go outside. She ran to her Master's bed. No other thought went into it except getting close.

Cooper heard claws on wood, swishing, breathing, and collar tags clacking against each other.

His blue eyes fluttered open and he was met with a full face of dog breath.

Chelsea was panting inches away and when she detected Master was awake, she let her long tongue loose licking the heck out of the smooth face.

"Okay, okay! I'm up...do you need to go outside?"

Chelsea sat down for just a second before jumping back up and spinning, running to the door, standing there waiting for the door to open by Master's hand "Oh I wish I could open a door by myself " she thought.

Cooper shuffled half asleep to the door and opened it and Chelsea shot out.

She had to sniff first but quickly so she could do her business. 

A technician monitoring the situation was amazed. This was his first animal and human swap and he was fascinated that in only a day, so much had changed between them. Monitoring their vital signs showed Cooper had a heartrate of 72. So did Chelsea. Their respiration per minute were also identical. It was the brain waves...Cooper's were much more active than Chelsea's. 

Chelsea was only using a small part of her brain whereas Cooper had activity in all quadrants. Then their was their muscle movement. After a week, the technician had to think that they would both be sore for months the way their bodies were adapting.

They fell into the pattern of their new lives. Chelsea's so much simpler, Cooper's so much more interesting and complex.

They both loved it.

Every time Cooper went to Chelsea unannounced to pet and give her affection, Chelsea's harness and program ramped up.

She loved getting scratched with Master's fingernails. It felt so good to her doggie senses. She found herself just devoted to Master, she would do anything for her.

Chelsea also began thinking of herself as himself. Being in Cooper's body and mind; she knew he was a boy dog. The dog part of her was driving every urge and need. 

Cooper was experiencing the life of a woman. It was all he knew of human life so it was very natural to him. The human part of him was driving him.

The week passed by blissfully for them.

The last night they had together, Cooper got down on the floor with her dog.

Chelsea perked up, her tail wagged as Cooper got up very close. He put his forehead up to hers. He felt the warmth of her fur, could smell her dog breath.

Chelsea smelled everything her owner had ate. She smelled her soap, her natural scent underneath all that. 

In a room a few hundred feet away, computers took off whirring fast, almost overheating as the programs ran. A different ending became possible. Cooper and Chelsea both saw it. Cooper pulled back, shock on his face as Chelsea barked a quick, firm yip.

Tanner returned for the end of the experiment. He had been getting updates and was astonished by them. He had seen live feeds whenever he wanted but seeing them in person was going to be different.

"So I guess this is it huh boy?" Cooper said as they got close to the end.

Watching outside, Cooper sounded like Scooby-Doo. You could almost make out words in his grumbling.

Chelsea was just barking at this point. And it didn't sound like a human barking. It sounded like an authentic dog bark. "Come on" Cooper patted Chelsea's side when the door opened and they came through into the first room together. 

Tanner gasped. Cooper was walking on his hind legs and somehow, Chelsea was smaller and had a more natural dog gait to her. Almost a loping motion but she managed to trot gracefully into the room; her hands and feet acting very much like paws.

"Cooper!" Came overhead in a loud voice and Chelsea perked up. You could see her ears move. She sat much more dog like than she should be able to do and panted.

"Chelsea" Cooper smiled and looked around. The whole room was now mirrors on all four sides and the door they entered in through vanished into them.

They stood facing a mirror straight on that reflected what they saw through the program but behind them, it showed their true selves; a dog on hind legs and a woman on all fours.

Cooper looked down at Chelsea at his side. He nodded "Who's a good boy?"

Chelsea's butt perked up and her tail wagged as she panted.

In the computer room, their banks of computers whirled louder as contingency plans engaged.

"What are they doing?" Thomas asked. The reflection behind them now blurred and changed to show a woman on the left and a dog on the right. The mirror image of their true selves had changed into the visions of the program.

"Shut it down and get them out of…" as Thomas yelled, they both broke into a run and dashed full speed at the mirror in front of them.

Instead of glass crashing, the two of them simply passed out of the room. In the blink of an eye, the room was simply empty. 

"Where'd they go?" Tanner asked dumbfounded. 

To the outside world,  it took less than a second but for Cooper and Chelsea, the world went into slow motion.

Both dove head first into the barrier. Arms and hands went up and to the side as Chelsea and Cooper whipped off their headsets.. The mirror image got closer and closer. Cooper's floppy ears and muzzle came right up to it but the image was of Chelsea rushing toward him. Blonde hair flowing, a look of grit and determination on that human face.

For Chlesea, she leapt at the barrier like a dog. The top of her head, only protected by her blonde hair came flying at the image of a Golden Retriever in full flight jumping.

The mirror was a barrier of static. No crash accompanied them passing through it but, absolutely everything else changed in the most amazing and drastic way possible.

In slow motion, the crown of Chelsea's head hit the barrier and began to change. 

Her head shrunk, the skull and brain encased in it were the first to change. Her hair turned to golden fur.

The tips of her ears passed and then her whole ears. They grew big and soft and very floppy as they turned into Cooper's ears for real.

Her blue eyes dulled and darkened. Human intricacies vanished replaced by dog eyes as her nose grew out into a muzzle taking her mouth with it. 

Chelsea spread her lengthening jaw out as her tongue grew long and thin. Her teeth changed into fully canine teeth as her fur continued to spread down over her chin and the back of her neck.

"I did it!" She thought as her hands passed through and she lost all dexterity, her fingers growing black claws and turning to stubby, hairy pads with no thumbs; dog paws replaced her human hands.

Her arms shrank down shorter and narrowing as her bone and muscle structure fundamentally changed shape and function.

Chelsea turned her head and saw Cooper start to pass through. The top of his head was expanding as his fur turned to blonde human hair.

His ears shrank down and away, completely hidden by his pretty blonde hair. His dull brown eyes sparked with human emotions and intelligence as they passed through. His fur vanished as if shaved off clearly by a laser in the barrier. 

His nose turned, his muzzle shrank and changed into Chelsea's nose, mouth, teeth and lips. His eyebrows and forehead expressed calm relief as cheeks, a jaw and a chin formed up creating Chelsea's human face and head.

"AAAAAHHHHH!" came out of his mouth a full vocal chords formed capable of full speech.

Cooper's paws passed through and once again the hair vanished as pads and claws turned to small delicate feminine fingers and pointy, painted nails.

His arms elongated and changed shape and functionality as human muscles took over.

Chelsea's shoulders passed through and her torso began to shrink and change to a dog physiology; more barrel chested and narrowing in length.

Her beautiful breasts sucked inside as thick chest fur covered her.

Cooper's shoulders passed through and rolled back changing his stance, center of gravity and balance. He now longer had a dog's build, he was becoming human.

His chest; the amazing sensation he experienced the first time was now intensified even more as Chelsea's breasts budded and grew enormous on his changing body. So sensitive that he felt the slight breeze on his nipples as his breasts bounced up and down in his movements. 

His stomach lined up as his hips popped dramatically. 

Chelsea felt her stomach rise up and knot changing position and, her diet and needs changed with it along with all her internal organs. Her hips flipped and pulled in a very different direction as they passed through.

They lost all human shape and function as muscles coiled. 

Also lost in the change was her human sexuality. Chelsea's vagina, uterus, fallopian tubes, her eggs...all gone. Her dog penis flopped as she arched her back for landing on her paws.

Her ass deflated to nothing; changed into a dog's flat behind but she shivered in delight as her real tail burst out in all its flipping glory.

Cooper felt weight shift and burst out behind him. Tight yet soft, firm yet yielding, he had Chelsea's ass.

His legs followed. 

Shifting size, shape, function and look, they went smooth and gained womanly curves.

Finally, his back paws passed through the barrier. The last of his fur vanished as his paws changed into Chelsea's tiny, delicate, feminine feet. No more pads and claws, toes wiggled as he tucked up to land with a roll.

Chelsea's body shrank even more. Her legs lost several inches as they shifted size, shape and function. Hair and muscle replaced her softness. No longer ever able to walk upright again, her feet passed through changing into her own pair of narrow and functional back paws.

She landed on all fours, her claws clicking as she started to bark happily. 

Cooper hit the ground on his shoulder and he rolled over. Flat on his back, his vision was quickly filled by a dog face overtop of him.

Panting above him was Cooper who leaned down and started licking him.

"We did it!" She cried out in triumph and shot her arms up. She wrapped them around her dog's neck and gave him a big hug as she unhooked both of their harnesses.

Cooper was Chelsea and Chelsea was Cooper. They had passed through the boundary and reversed their roles by their own choice. They had made VR actual reality. They had managed to switch bodies and therefore lives with each other. Their roles were reversed. They had each other's body, abilities and gifts. Just like they wanted.

Tanner and Thomas and several technicians burst through a door "Oh my God! What happened?! Are you okay?! Is everything alright?"

Chelsea was hugging on Cooper's neck. Chelsea was nude, Cooper was just furry. Somehow no clothing had made it through the week.

"Yeah! Of course everything is alright! Better than alright actually...that was awesome! Amazing even...isn't that right boy?!" Chelsea rubbed all around Cooper's neck and he panted happily and gave a quick bark.

Tanner rushed over and hugged his girlfriend hard. 

As Chelsea accepted the hug, her right hand went over and continued to pet Cooper around the ears.

Thomas picked up the discarded headsets and harnesses which were lying in a pile together and gave Chelsea a skeptical look.

"Let’s get you dressed first of all" Tanner said helping Chelsea to her feet.

Chelsea just winked at Thomas "Thanks! You were right. This experience will absolutely change your life"
