Brandi was tired. She yawned and stretched and went to lay down.  She fell asleep almost instantly.

Lily decided to help her out. She went into the Memory tab and pulled up Subject 2. It showed how long and how much memory capacity was available. Brandi's settings were much lower than Lily's. This was one area where they could be adjusted individually. Going back 24 hours, Lily scaled Brandi's memory capacity up to human levels.

She went into the next tab 'Share Memories' or 'Transfer Memories'. Lily chuckled, "What would it be like if I only had Brandi's memories?" She pictured food, squirrels and her favorite places to nap.

Lily clicked on 'Share Memories'

It was a good thing Brandi was asleep as 27 years of human experience flowed in and became hers.

Brandi's brain stored it all. So many more things became natural to her, desired by her.

Lily was smiling seeing Brandi's paws and mouth and ears all twitching as she lay sleeping.

She looked down at her phone as an alert came up 'Subject 2 Mental Traits have adjusted. Please review'

Lily clicked into 'Mental Traits' and every field was highlighted for review.

Lily's jaw dropped. She went into Memory and watched as a slider on Brandi's line steadily increased.

She went into Intellect and Intelligence and into Subject 2. Numbers were steadily rising. IQ chief among them, but other numbers were increasing.

Lily checked her own and there were no changes. Several new memories were in her head. Brandi's memories. She remembered all kinds of things that simply warmed her heart. Being a puppy. Obedience training. So many walks. Other memories were simply swirls of colors and blurry objects.

She saw herself in 3rd person form in Brandi's memories and her heart swelled.

Lilly continued to go into different Mental Traits and see the numbers rise. Reasoning, Speech and Vocabulary, Numerical Ability, Spatial Awareness and Capabilities; Brandi's numbers now read in human range.

Perception was the next one. Lily saw the lines Subject 1 = Master or Subordinate

Subject 2 = Subordinate or Master.

"Does this mean we're equals?" Lily asked herself.

Lily couldn't describe her feelings. Such a mix of daring, fear, enchantment, delirium, intoxication, elation, euphoria, unease, angst, anxiety, awe, disquieted, audacity, and recklessness. But whatever it was, it was now a driving force of compulsion, an addiction.

She sat back and let Brandi's memories merge with her own.

When Brandi woke up, she was so confused and overwhelmed. Her head lifted and she looked all around. Including herself. Lily sat up seeing her up but she didn't say anything. She was making different noises. Growling, guttural with slight whines and whimpers.

She looked around the room and then walked down the hallway to Lily's room.

Lily followed and found her sitting in front of the mirror.

Lily's stomach flipped again.

Brandi was concentrating on the image there until she looked at Lily and let out more growls and grunts.

"You're mentally capable of talking but not physically" Lily said to her.

Brandi had a different look in her eyes. Her brow furrowed as she continued looking.

The dog got up and went into the bathroom.

Lily heard her dog sigh and Lily followed her to the door.

Even further behind the tree. Lily went out and hung up a blanket from the tree to her garage to give Brandi the privacy she now needed.

Brandi trotted back in looking happier.

Lily sat down on the floor and patted her lap. Brandi came over and sat in front of her.

"I know there's a lot of new stuff that you woke up to. I shared my memories with you. With that came a lot of knowledge from school. That's why you were so confused when you woke up" Lily explained and Brandi nodded. "If you're happy with this, Bark once. If you want me to change it back, Bark twice"

<Bark>

Lily's eyes widened and she rubbed Brandi's face "Good Girl! That is so awesome! You understand me and you like what's been happening"

<Bark>

She pawed at Lily's side. The pocket where her phone was.

Lily brought it out with a sly grin "You sneaky girl! You want to do some more!"

<Bark!> she started to bounce happily.

Lily wrapped her arms around her dog's neck and chest and she hugged her tight "Oh I love you so much Brandi and I am sssssoooooo happy we're doing this! This is the most exciting and thrilling thing I've ever done!"

<Bark!> Brandi laid her head down on Lily's shoulder and pressed down. She gently licked her cheek as Lily stroked her back.

The doorbell rang and Lily got up and brought in her Door Dash order for dinner. She opened up and laid out 4 cheeseburgers. Brandi drooled.

"Not yet. I've got something special in mind for us" Lily said as she brought out her phone.

'Physical Traits' Ears, Eyes, Nose, Muzzle, Teeth, Tongue, Hair/ Facial Fur all were marked.

A new choice appeared: 'Taste Buds' "OH absolutely!" Lily said, clicking it.

She went to Paws. 'Trade both hands for front paws' appeared and she added it to the list.

Lily then went to 'Arms' and added 'Trade both arms for front forelegs'

She set the timer for an hour. "This might be a little weird at first for both of us, but then again  this whole thing is really weird in the first place. You'll adjust and you'll be just fine" Lily explained and Brandi listened. "It will be for an hour" she added as she clicked on 'Trade all selected traits'

It was by far the most physical trait they had swapped yet. Brandi felt the tingling and the satisfying warmth fill her body, concentrating in her muzzle and face.

She howled in a gracious tone as her muzzle began to shrink back, taking her tongue and teeth back with them.

Her tongue shrank down and thickened as her teeth dulled, widened, flattened. They grew larger in some cases and shrank in others as their form and function changed.

This time, Brandi got an additional tingling inside her mouth as her taste Buds changed.

Her lips plumped as they shrank down over her small mouth. But this time, the changes kept coming. Her chin and jaw changed. Her cheeks spread out wide and parallel as her face broadened.

<Rowr?!> She added in confusion as her sense of smell dulled so dramatically. It was like she could barely smell anything. Her nose itched as it took on Lily's form.

Realizing what was happening made it better "Human smell and taste!" She thought.

But there was still more. Her eyesight popped in crystal clear as her eyes swapped and became Lily's eyes. Tears of joy formed up; Brandi loved the colors.

Her forehead shifted as eyebrows formed. Her fur had been steadily receding leaving just skin behind.

Brandi gasped as she felt hervears warm up.

Her big, pert and alert ears started to shrink down. Brandi's hearing muffled just as dramatically as her smell had.

Her ears slid, shifting lower on her head and moving to the sides as they shrank down into human ears.

Lily's brown hair broke out atop Brandi's round head. It grew out to her length and style, feeling very strange to Brandi.

Just when she thought it was over, the gratifying tingling moved to her paws.

Planted firmly against the floor, her paws began to become hands.

Her claws turned pale and flattened as fingers stretched out. Thumbs formed. Both paws were turning into hands. Brandi was thrilled as the fur receded, she wiggled out her fingers but this time the tingling moved even higher.

Her fur vanished on her front legs as they grew longer and larger "Arms!" She said, Brandi's voice had returned to her "I've got arms! Real arms! Human arms and hands! Thank you Lily!"

Lily was no longer able to speak so she just let out a <Bark>

Lily's own changes began with the desirable warmth and tingling rippling through her body. "Better than sex" she thought to herself.

Lily bated her teeth as her lips thinned and elongated. Her muzzle was returning and pushing out. Her teeth sharpened and shrank in most cases but her incisors grew long and sharp. Her tongue thinned and grew so much longer as it kept up with her muzzle.

Lily's eyes widened in surprise and anticipation as her taste buds changed into those of a dog. Her chin and jawline pulled into shape.

Lily's mind nearly exploded as her sense of smell changed. She had no words for the overwhelming sensations that rocked her to her core.

Unseen, her Instincts and Mentality slider began to adjust. The swirling cloudy memories became crystal clear in her mind; they were scent memories, they all unlocked and a flood of memories added to her mind.

Her nose flattened and turned a reddish black. It flared constantly as she cataloged every possible scent in her vicinity.

Lily's cheeks ran back as her whole face and head changed shape. Her eyes were further offset so this time as the colors drained, she also gained peripheral and motion vision, things natural to a canine. It gave her a more complete picture.

Fur sprouted and spread across her face and muzzle as her hair receded.

Her ears warmed up "OH God!" She thought as noises amplified and cleared like never before. Her ears were stretching up and out, moving from the sides of her head to the top. Lifting higher, fur coming out as they formed into high triangles. The tips flopped over at their peak.

Lily put her hands to her muzzle and she felt all around getting her whiskers too.

"This is amazing!" She thought just her fingers stiffened and started to fuse together.

Her thumbs slipped back as her nails turned into black claws and her thick pads popped out.

A new thrill ripped through her as her arms started to thin and shrink down. More rust and red and tan fur covered her paws and her new forelegs.

"AAAAAHHHH! I love it!" Brandi squealed seeing the two of them.

They both needed several minutes to adjust and to figure out how to walk, but they did it.

Lily was drooling, smelling the cheeseburgers. She walked over and got down on her knees and her forelegs and paws before her bowl. <Bark!>

Brandi felt such an odd tingling inside her seeing that. She had never felt better or more excited before. The role reversal and Lily's willingness, her eagerness to switch not only bodies but minds and roles moved her in a passionate way that awakened so many feelings. Brandi's emotions were aflame.

She made her way to the counter and stood up. Her stronger and longer arms made it easier but her legs still left something to be desired. "Is this what you want?" Brandi teased as she grabbed two cheeseburgers.

Lily panted <Bark>

"Oh I bet you do! Who's a good girl?! Who's my good girl?!" Brandi asked her.

Lily on her knees before her begged <Bark!>

"Yes you are! Are you hungry?!"

Brandi placed the burgers in Lily's bowl and Lily dove for them.

Brandi watched absolutely fascinated as Lily devoured the burgers in huge chomping bites out of her bowl.

Lily had never wanted something so bad and had to wait for it to be given to her. The food smelled so good. She appreciated Brandi's words, they made her feel warm in a different way but she wanted to eat!

Something inside Lily changed when she was fed by Brandi. Then it only deepened as she ate her food like the animal she was. She licked the steel bowl clean and then lapped up water with her long, cupped tongue.

Brandi was balancing on her hind legs while her elbows steadied her on the counter. She held her burger in her hands and took careful, small, calculated bites.

Lily watched her as she savored her meal. "How can she take so long to eat?" She thought.

Lily remained on her knees and paws and she walked all over the house sniffing everything, getting scents she never knew were there before.

Brandi finished her burgers with a new appreciation for food. She had to bend her elbows and her hands slapped at the floor as she made her way to the mirror in the bedroom. "That's what I look like," she said to her reflection.

It was ridiculous. A human head atop a Doberman body with human arms and hands but, coined with memories and her evolving thinking, it represented endless possibilities.

Brandi had experienced all the main 5 human senses now.

She made her way back to the kitchen, Lily was sniffing the bag of dry dog food.

Brandi smiled and opened the bag as Lily sat back and panted "Are you still hungry?"

<Bark>

Brandi dug out a cup of kibble and put it in Lily's bowl.

Lily dove in crunching it, savoring it, swallowing down her food and licking the bowl for crumbs.

Brandi sat and Lily curled up with her on the floor together.

The sheer pleasure of what happened next fundamentally changed both of them forever.

Brandi began to scratch and pet Lily's head.

Lily was in ecstasy. Pure joy ran through her, she had never known anything so relaxing and enchanting. It felt so good.

Fingers and fingernails scratching and applying pressure around her ears and on the top of her head. Pure joy. Heaven.

Sensing how happy and content Lily became at her touch also changed Brandi. She could provide for her. A feeling of delirium and delight rushed up inside her. Lily's source of pleasure was her. Lily's source of food and water could depend on her. Brandi loved this.

Lily needing her, Lily wanting her. Brandi was getting her own sense of pleasure from petting Lily's short fur. She ran her hands over Lily's forelegs and paws. She squeezed Lily's paw pads. "You're so soft…you are such a pretty girl!" Brandi told Lily. Lily wanted to wag her tail in happiness. She panted trying to smile for Brandi.

Brandi nuzzled Lily's muzzle and gave her kisses.

Every touch from Brandi's hands or lips, even her rubbing her cheeks up against her started a new wave of joy in Lily. Lily licked Brandi's face. Then she licked her hands "Master is so good to me" Lily thought.

Brandi put her forehead against Lily's. She had her hand on her muzzle as she stared into Lily's amber brown dog eyes.

Holding her muzzle closed while keeping her eyes above Lily's eyes asserted her dominance.

Lily didn't resist.

They were like that when they felt the warmth and tingling return.

"Oh…time to go back" Brandi said "Now before we do, just remember that I am always ready for another change. I want to be fully human at some point. I'm not rushing you but, it would make me very happy if we could switch everything! Okay?"

<Bark!> Lily understood.

"I think you're going to love being all dog too! It's awesome being a dog!"

<Bark!!>

Lily felt her arms stretching out, the fur there thinned and she whimpered as her arms reformed.

Her thumbs slid back into place. She watched her paw pads shrink down. Her palms returned. Her nails turned pale and flattened as she lost her claws. Her fingers pushed out and she wiggled them regaining feeling in them.

Brandi's elbows straightened out as her arms shrank down and changed back into her forelegs.

Fur spread down as her thumbs slid backwards and her fingers fused together. They rose up.as her pads plumped out. Her thin nails curled, curved, grew and sharpened back into her claws.

As Lily's muzzle retracted, Brandi's grew. As Lily's ears shrank, Brandi's grew.

Their faces moved continuously as they reverted back.

Lily felt a pop in her throat as she regained the ability to speak.

Her tongue, teeth and mouth had returned. Her whole face was taking shape as her fur and whiskers retreated back under the surface.

Her hair grew back as her nose grew back.

She shook her head.

Lily's teeth bared as they returned to canine form. Her tongue grew as her muzzle pushed out and her nose retreated.

Her ears perked up as she blinked, losing her human sight but gaining her hearing and smell again.

Lily blinked as the color returned to her world. It was so bright.

Lily was exhausted. Drained. She curled up on her side.

Brandi was exhausted too. She burrowed in right next to Lily.

Lily threw her arm over Brandi and tucked her legs up to touch her as well.

Lily put her mouth up against the back of Brandi's head. She kissed her gently as she petted her side and belly. "I heard and understood what you said right before we changed back. I think I'm going to call off sick from work tomorrow so we can do it"

Brandi lifted her head. She got up and licked Lily's face enthusiastically.

Lily hugged Brandi's neck as she sat back down.

Lily went to the door and they both went out. They looked at each other. "I know you're embarrassed now" Lily laughed "Tomorrow it can be me out here okay!"

That got Brandi moving.

It was dark out but it was a nice clear night. Lily looked up at the stars so Brandi could do her business.

Lily stepped barefoot into the cool grass. "What's it going to feel like under my paws?" She wondered "So many new things to discover tomorrow" she said as Brandi returned.

Lily got ready for bed as Brandi watched her intently. She hopped up at the same time Lily got in.

Lily checked the app as she lay there. She went into Perception.

Subject 1 = Subordinate

Subject 2 = Master

Her heart beat faster. She swallowed as she clicked into the tab 'Unable to change at this time' came up. Lily didn't say anything about this fundamental change. She knew deep down that had become true. She felt it.

She went into Instincts and Mentality. Under her slider, it had gone way up, up into the lower regions of canine behavior.

Lily patted Brandi as she checked her numbers; they had only gone up higher. "You take good care of me tomorrow okay"

Brandi looked back at her <Bark!>

"I know you will. You're my good girl!" She paused, "Or am I your good girl?"

Brandi slept on her side. She was dreaming about college. She was walking from class to class. Shorts, a sweatshirt, Birkenstock sandals on her feet, backpack slung over her shoulder, hair pulled back in a low loose ponytail.

A lecture started and she was sitting at a desk writing notes as the Professor talked.

The dream changed. She was at work. A long loose skirt, black flats, a flowered blouse as she diagrammed sentences for her 4th grade students.

Lily was dreaming about school too: Obedience school. She was on her lead as her Master gave her commands. She sat, gave a paw to shake, held still as a treat was placed nearby until she was told she could take it.

Brandi woke up early. It was still dark out but she heard Lily talking on her phone "Yeah, I'm so sorry to call off sick but I've been up all night ill…I hope I can come in tomorrow. If not, I'll give you a call…Thanks Trish"

Lily noticed Brandi's head up "Good Morning gorgeous!" She giggled and smiled, squirming and tucking herself down "Are you ready for our big day?!"

<Bark!>

They got up and walked from the bedroom down to the kitchen and living room area.

Brandi sat attentively on the ground. She wasn't going outside. She would hold it.

Lily sat on the couch as she went through her app. "I'm setting the timer for 12 hours. So a little after 6 tonight we will swap back"

She chose the top option 'Swap Complete Physical Form' she whole body was fluttering. 'Swap Internal Organs and Systems' she added to it.

She went into Mental Traits and went to Instincts and Mentality. She moved her slider to completely dog. She moved Brandi's slider to completely human.

She adjusted Intellect and Intelligence, Personality, Memory and finally Concept of Self.

Lily hadn't messed with this setting yet but for the day, she moved both of their levels to 50/50.

She kept Awareness on fully aware of being swapped.

She let out a nervous hiss of air as she clicked Done.

All their changes came up on screen with a swirling wheel 'Preparing…'

'Trade all selected Traits'

Lily felt warm already. Excited and scared, she asked "Are you ready to become a human?"

<Bark!>

Lily took off her clothes. She was just wearing panties and a tank top but she knew she needed to be nude for this. She looked down at Brandi who was looking back up at her.

Lily put her finger down.

She went numb. A total weightlessness overtook her body. She was only vaguely aware of the floor beneath her feet; she could have been floating for all she knew. "Aaaaaahhhhh!" She let out and Brandi howled in unison with her.

Brandi was just as freaked out by the feeling creeping, crawling over her. The first she noticed was color flooding in. Her eyes changed first so she could see everything!

Lily's stomach growled loudly. Her insides were beginning to rearrange themselves.

Brandi felt it too and she let out a low whine. The warmth finally managed to take hold of both of them. Heat, electricity now running over everything, through everything. The tingling had never been this intense before.

Lily panted. Her body now began to change and she began to shrink down shorter and more compact. "Brandi!" She moaned out. Her breasts were receding, shrinking back into her chest as rows of nipples appeared.

Brandi was starting to grow. Her hind legs were lengthening and filling out. Her forelegs were stretching out longer.

Brandi's hips popped. Her shoulders rotated. Her alignment was changing from canine to human.

An other worldly excitement was building in Brandi. It was getting harder to stand like a dog.

She looked down seeing her nipples disappear except for the top two.

She looked at her back paws.

They were shrinking down, widening and trying to go flat. The fur there was almost gone so she could see toes taking shape. Feeling came to them, flexibility as her toe pads became actual toes. Her claws flattened and turned pale as they thinned to top her toes.

Her feet widened as they changed to Lily's feet. Her calves, knees and thighs shimmied as they grew and changed.

With a loud <POP> Brandi's waist and hips aligned and she stood upright.

She felt a tickling in her throat. Her face was changing again. He let out a gasp and then a very human sounding "AAAAAHHHH!"

Brandi's fur was very thin, like peach fuzz all over her body.

Her stomach growled as her internal organs shifted and changed, rewriting themselves, resizing themselves, rearranging.

Lily felt her hips slipping. Down and backwards as her legs began to shrink. Mass vanished quickly leaving behind sinewy muscle and tight skin that was filling out with rust and tan fur.

Her feet were narrowing as bones popped and realigned.

She was having a hard time standing like a human.

As her toes fused together and her pads began to plump up on her rear paws, she shuddered. Her hips popped and she went down.

Lily was still shrinking as she sat on her haunches and watched her feet finish transforming into paws.

Sitting like a dog, her chest reformed and shuddered as it compacted inward and downward. "AAAAAHHHH!" She let out.

"Lily?!" Brandi squealed

"Brandi?!" Lily replied excitedly.

Lily's muzzle was pushing out "Master?!" She added as it grew longer and a tickle in her throat confirmed she could no longer speak.

"Yes" Brandi replied feeling butterflies erupt in her stomach at the words.

Lily's mouth moved but growls and whines came out instead of words.

Lily dropped her head. Her vulva thickened and began to slip backwards. She howled in response to the reworking of her entire reproductive system.

Lily got excited though as she felt pressure at the base of her spine. Her tail was coming back.

Brandi's tail was pulling up and inward as Lily's shot out.

Brandi lost control of it. She couldn't move it on command as it shrank down. Lily however, could control her tail masterfully; it whipped and thumped on the ground.

Brandi warmed up even more as her vulva moved. It was shifting position to between her legs. Her human legs.

Her hips shifted outward and her ass plumped as her tail vanished. She hummed as pure pleasure coursed through her body. Her clit formed up and engorged at the same time her boobs grew out.

They swelled and grew round, hanging up before falling into natural place on her chest.

Lily shuddered as her shoulders rotated and herchest became barrel shaped. Her arms shrank and she let herself fall forward and stretch her back out.

Standing just like a dog, Lily felt her neck shift and thicken. Her forelegs thinned and her thumbs slid backwards. Her fingers fused and her hands turned to paws. Claws appeared along with pads.

Lily's face had steadily been changing the whole time so by the time her body had changed, her head was just about complete as well. Her ears sat up. Her muzzle was out to full length and her tongue lolled as she panted, her sharp teeth waited.

Covered entirely in rust and tan fur, the last of her hair receded away.

Lily's eyes were the last thing to change. She had been able to watch her own changes along with those of Brandi.

Brandi's paws spread out, her fingers stretched outward wiggling as she gained full feeling in them.

Her face had been taking shape. No signs of a muzzle remained. Her lips,mouth, teeth, tongue, nose, chin, cheeks, jaw and forehead were all in place and in line. Her ears were the last thing to change.

They shrunk down and slid lower to the sides of her head. The were still pointed at the tips. "Ah!" She let out as they rounded off.

Brandi closed her eyes as further changes ran through her internally. Lily howled as she too felt internal changes still occurring.

Mental changes geared up. They both froze where they stood.

Then, a chill ran through both of them. Lily shook, Brandi shivered from head to toe.  The electricity surrounding them dissipated and they knew it was complete.

Brandi looked at the phone and saw it say 'Changes complete. Traits Swapped' 11:59.

The timer had just started on them.

Brandi looked around. Everything looked different to her from this height and vantage point.

Lily cautiously lifted her front right paw.

Lily walked cautiously, like she was high stepping.

Brandi giggled watching her. Her former Master was now her pet. Her dog.

As such, Brandi grabbed her collar.

Lily was not paying attention to Brandi until she felt her hand on her back and the collar cluck around her neck. She shook and heard her tags clnk and jingle.

"I'm going to have to order you a tag of your own! One that says Lily on it!" Brandi squealed delighted.

Brandi saw the clothes sitting nearby. She put them on and added a pair of shorts that sat there too. "Better than fur if you ask me?"

Lily felt it. She looked around. Then she made her way to the door.

She looked out and heard Brandi's delighted laughter behind her.

"Your turn Lily" Brandi said as she opened the door for her.

Lily stopped dead in her tracks, the onslaught of smells and sounds hit her and everything else melted away in pure bliss.

"Go on" Brandi encouraged her, patting her side.

Lily sniffed the air and the grass. Her gait was getting better, more natural as she searched for the perfect spot.

The air felt different to Brandi. No fur made her colder but it was a small price to pay.

Lily found her spot and went to the bathroom right in the middle of her yard.

Lily was living what felt like a dream. She was a dog! She had physically and somewhat mentally transformed into her own dog.

That dog was now her. A dog turned human as a human became a dog.

They had swapped bodies, exchanged species, traded intelligence: She had willingly given her humanity away and had taken the mentality of an animal in its place.

Lily looked at Brandi who was breathing in deeply, standing barefoot in the grass. "My whole world, my survival depends on her"

Lily shook and shook off her thoughts. She started to trot. Then run. She started digging in, full strides as she did lap after lap in the yard. It felt amazing. So free.

Brandi laughed and clapped and cheered her on "Go! Go Lily! Gets those zoomies out!"

Lily skidded to a stop, panting but so happy. Her muscles were just getting loose. She went around sniffing. She didn't care that Brandi went back inside.

Every step felt different. Footfalls. No paws. Feet. Hands. Legs, arms…"I'm a person. I'm a woman" she said to herself and the air in the room. "I still can't believe this is real. That this has actually happened to us! I'm real! I'm standing here in this body. It's mine!"

She went into the bathroom and closed the door. Sighing with relief, she kind of freaked out, but held it together.

She sat in a chair and reclined.

She picked up all kinds of things, feeling the weight in her hands.

She checked on Lily who was still very interstate in sniffing.

Brandi ate chocolate. "Oh my God that is sssssoooooo fucking good! What else have I been missing?!" She melted at the delicious taste.

Lily came up to the door and scratched to get her attention "Well Hello little Miss Lily! Did you have fun outside?"

<Bark >

"I told you being a dog is awesome! I wouldn't lie to you" Brandi said " I am loving being human too thanks for asking" she added. "This view is great on 2 legs!"
