Harper figured it would be easy, going through a week of the 6th grade when she was almost a college graduate but she was in for quite a surprise.
It was gone. Harper sat in first period which was pre algebra and she barely understood any of it. She felt hot, panicky. She searched her brain, digging and clawing. "I've taken physics! Calculus! Trigonometry!! Why can't I understand pre algebra without it having to be explained to me like…" it hit her "It's the program. It wouldn't be fair right? It wouldn't be fair so I have to go through this like Maddie would...I get it"
Everything shuddered again. The room blinked. "What was that? Glitch in the Matrix haha" Harper told herself.
Her education had just left her. Transferred to her sister. All knowledge she had acquired since three weeks left in her own 6th grade year was no longer accessible to her. She had her sister's education level.
Maddie sat in her first class of the day. She had been striving for, waiting for. It was a class called Caring for the elderly 2. It made some sense but not totally.
She concentrated listening to her Professor when everything shuddered. The room blinked. "What was that?" Maddie thought. She looked around, remaining in her seat. She could almost see the edge of the program. A fuzziness but only for the blink of an eye. Then, a newfound sharpness.
Still it felt like Maddie was moving in slow motion. She felt individual breaths. She had been sitting with her ankles crossed beneath her and it seemed forever to uncross them and put her feet flat on the floor.
"As you will recall from last semester, patients with dementia often suffer from?" The Professor looked up. Maddie felt her hand raising. "What am I doing?" She felt heat all over her body as her mind scrambled for the answer, digging and clawing at the recesses of her mind. And then, it was there
"Imparred Circadian rhythms since circadian rhythms are generated in the suprachiasmatic nucleus and degenerated nucleus are common in that population"
"Very good Maddie" the Professor replied and continued.
It was all there. All of Harper's knowledge and education lay open before Maddie. Fully accessible and all hers.
She realized she had full high school and college knowledge in her head. Not in the program. Her mind was now at Harper's education level. "Holy Shit" Maddie thought, realizing what had just happened. "Full, actual transference of education. Part of my mind is now fully Harper which means...she lost it. She must no longer have any advanced education. She has my mind and my education now...she's really been reduced to a 6th grade level while I've been elevated to this"
Maddie's throat was dry.
Jean stormed into the control room "What the fuck is happening?!"
"Ma'am...I don't know" the technician admitted standing in front of the monitors slack jawed. "One minute it's fine, running smoothly and then I've never seen anything like it. No simulation has ever ran this"
"Do you think I run my sector like idiot boy Thomas over there! I haven't had a full transference event yet and I am determined to keep it that way. Reverse it!" Jean demanded.
The technician began backing up the data but nothing was going through. Just error message after message. "I'll do it myself moron! Move!" Jean said inserting her key into the panel for full Supervisor override.
"Access Denied"
Jean growled and furiously typed command after command.
"Access Denied...replaying event" came up on screen.
Jean scowled at the screen as the program put out its calculations and the protocols it followed in adjusting base brain activity, upping 64Bs base while decreasing 64As until full transference was achieved.
Jean stared ahead. There was nothing she could do. The program wouldn't. Couldn't reverse "Back everything up for both of their brain activity. I see their maturity levels have adjusted somewhat but not entirely. If we do a full backup we can do a full overwrite when it comes time for them to step out of the program. We can override this change at the end and fix it still. You need to be extra vigilant on this case"
"The program seems to have control. I don't know what I can do" the technician said. Jean didn't want to admit it, but it appeared he was right.
64A had a maturity age of 15 currently while 64B was reading 16. As they watched, it ticked upwards 17, 18, 19. Jean just stared "Fuck"
Harper had justified her reduction in intelligence "No, not intelligence, just education. I can’t be a show off" and she went through her school day more interested in her friends than the subjects.
After school was softball. Harper had never been good but Maddie was a star.
Harper changed her clothes and into her cleats and grabbed her glove. Just throwing, she knew she had Maddie's ability "This is sweet! I'm a jock now!"
Harper was whipping the ball and it felt natural to her. All her catches were nonchalant as she talked with her coach Mr. Smith who was also her gym teacher.
She hit every pitch thrown to her and practice was a breeze.
As the technician watched, more numbers changed. This time it was muscle reaction times, reflexes. 64As numbers increased as 64Bs decreased "Great...athletic ability just swapped"
Maddie was at work. She worked at a nursing home as an Aide. She felt that weird shudder again and panicky, she scanned her mind which seemed unchanged. She tripped over her own feet though as she walked down the hall.
Harper had dinner with her Mom and then chatted with her friends all night on various social media apps.
Maddie made herself dinner and chatted with her friends all night on various social media sites.
Tuesday was similar for Harper except it was swimming practice. "This is the real test" she told herself as she got on her suit and tucked her hair up into her swim cap.
Maddie loved swimming. She swam for a Club team and had been swimming competitively since she was 5. Harper had to plug her nose when she jumped in the water.
But now, Harper got into her blocks and she left naturally. When her coach blew his whistle, she dove in flawlessly and had perfect form including kick turns. Something Harper had never done in her life. She loved the feeling of her body in the water. How coordinated she was, the rhythm of it. The kicks, the turns, the way she pulled in her breath. She didn't want it to end.
As the week went on, both of them found themselves fully immersed in the other's life. At times, their old original life was merely an afterthought.
Harper had dressed up several times as she went out with friends on Tuesday and Friday night. Maddie loved every second of it. The heels, the dresses, the makeup. Getting ready, taking time and pampering herself. "I can never go back to sports. Yoga is plenty for me these days. It feels so much better to pamper myself"
She let the program run through Tuesday, which was Karaoke night out with her friends.
Hair and makeup done, wearing a short and low cut black dress along with the 3" wedges.
Maddie knew Harper had picked this look out just for her. Tempting her, teasing her. "Did she want me to fall so in love with being her that we can't switch back? Because if that was her goal, it is totally working" Maddie laughed talking to herself in the mirror.
She took in every centimeter of her body. Every little detail. Memorizing it. The desire rose up in her "Please keep me like this. I want to be Harper for real so bad! But I also hope that Harper wants to become me. I don't want to, to take or steal her body and life and have her hate me so please make this feeling mutual. I'm praying that she's enjoying her time as me as much as I'm loving being her. Maybe she even wants it more than me. Maybe, just maybe I have enough to offer her to want to go back and become me permanently" Maddie pleaded before she left her apartment for the bar.
Drinking White Claws and singing a terrible rendition of You Give Love A Bad Name with her friends, Maddie had the time of her life.
Harper was afraid to admit it. As Wednesday worked its way through, she knew it but she wouldn't admit it to herself. She dominated her softball game pitching a shutout and getting 3 hits and 5 RBIs.
She sat on the bench in the dugout after the game packing her bag, getting congratulated by not only her team and coaches but the opposing coaches as well.
She unlaced her cleats, her socks were sweaty and dirty and she could see her toes outlined in them. She felt a tingle.
She put on a pair of slides, the stirrups of her softball socks hung back undone at her heels flapping as she put her cleats, glove, face mask, and batting gloves in her bag and slid her bat in along the side.
She tugged at the tight braid her hair was in as she slung her bag over her shoulder to walk to her Mom's car. The thoughts were right there. She knew it was true but to admit it to even herself, well, there was a finality in that. But the tingling persisted as did the thought.
Michelle went through the Wendy's drive through for their dinner and it tasted so good to Harper.
Once home and cleaned up, Harper lay on her bed, she could still smell the dirt in her nose even though she had just showered and her hair was soaking wet.
Harper sucked in her bottom lip, she did it all the time now and never thought about it "Okay. Time you actually acknowledge the truth...you can't deny it anymore" Harper sighed out loud. She was lying stiff, her hands clenched into fists. "You don't want to switch back. You're happier as Maddie as you hope, HOPE! That when it comes time to go back to being; yourself, to being Harper again, that it doesn't happen. You want what Maddie talked about; you want a malfunction so you can stay like this"
The tingling was increasing as Harper talked to herself "Yes alright! I want to become Maddie full-time and never look back. But I don't want to steal it away from her. We live such different ways. I'm not athletic but damn it I want to be! I'm loving having Maddie's athletic ability and...honestly, it puts off adulthood"
Harper got up and started to pace "It's obvious that she wanted to be me and I know that isn't going to change after she gets to do the stuff I set up for her. It should only make her want it more so…"
Harper stopped in front of her mirror "Please God, or whoever or whatever might have some say in this: Please let me stay like this. I have never wanted anything more in this world than to actually switch bodies with my sister. I want her to have my body and my life. I want hers and I know she wants mine so please, for all that is fair, please make us really switch places"
Harper looked around the room and tears came to her eyes "I don't want to give this up. I don't want to go back" she looked in the mirror again "This is what I want to see! I don't want to ever look in a mirror and see, and see...my big sister staring back!"
Thursday came and went for both of them. Maddie had classes and work and Harper had school and swimming.
While Harper was talking with her friends at around 9 that night, she decided to try something. Her heart was pounding as she texted her big sister. She smiled, pulling up Harper on her phone and simply texting 'Hey how's it going?'
Maddie was reading when her phone went off. Her heart started racing seeing who it was from and the message. "I didn't text her that week! Harper broke the program and went outside of it! OMFG!"
Maddie's hands were shaking as she typed back 'OMG! It's going great! How are U doing? It's awesome to hear from you!'
Harper didn't even know if it would work. She knew they hadn't communicated during the week. When she got a response, an enthusiastic response, she could feel her head pounding along with her chest. 'Doing great. I'm having a lot of fun' she sent back.
Maddie didn't want to push too hard 'Awwww I'm so happy to hear you're enjoying it. How's softball and swimming?'
'OMG I Absolutely LUV playing sports now! I'm hooked haha' came the immediate response.
Maddie smirked and took in a deep breath 'my yoga loving sis, now a jock haha. I knew you'd like it' Maddie text back.
'And how's yoga going for you?'
'I love it! I feel so flexible and it really relaxes me… Maddie paused and decided to push her luck ...I think I like it better than your sports' she sent off nearly passing out with anxiety.
Harper read the latest text "your sports?! Is she saying that softball and swimming are...mine?!"
Harper decided to up the game 'Hehe whatever "big sis" I guess you're the prissy one now and I'm the little jock huh?'
Maddie nearly fainted.
'Sure "little sis" haha. I kind of like the sound of that. I could get used to it' Maddie was so worked up, she felt like she was floating.
Harper's jaw dropped seeing the response. She read it over and over 'I'm game if you are Harper' Harper typed back. She had never been so scared in her whole life.
Maddie dropped her phone 'OMG! Are U serious?!!!!!!!!!!!!'
Harper exhaled seeing the response "ohmygod we're switching!" She thought as she typed back 'Absolutely!'
'Please tell me you're not joking. I want to be you so much!'
'And I want to be you so much! I'm totally serious! If you want to switch places with me permanently just text back Yes' Harper sent it.
She couldn't swallow, she couldn't move. She saw Harper is typing pop up before 'YES' came up.
'You've made me the happiest I've ever been in my life' Maddie added in another text.
Harper smiled 'no you've made me the happiest girl ever!!!!!!! Yes! Thank you!"
'Thank you...Maddie!!!!!!!' Maddie text back.
'OMG you just gave me butterflies calling me that! I can't wait to be called that!'
'Well that's your name Madelyn! I can't believe you're going to be my LITTLE SISTER! AAAAAHHHHHHHH!!!!!!'
Harper flipped on her camera and took a selfie and sent it. The look of immense happiness was blatantly obvious.
'Awwww look at my baby sister! Sooo adorable!' Maddie took a selfish and sent it back.
'And there's my gorgeous older sister!'
They went back and forth a while longer before finally the program caught up and moved them to bed.
"So I see you lost control!" Jean dressed down the technician on duty. "Now there's absolutely nothing we can do to prevent a crossover event!"
Jean looked at the monitors and numbers before throwing them into the technician's face.
When Maddie woke up on Friday morning, the first thing she did was grab her phone and read back the text conversation from the night before "It wasn't a dream! We really agreed to swap for real!" She was squealing internally as she danced around her apartment.
Harper's alarm went off super early. On Fridays she had swim practice at 6 AM. She bolted up in bed gasping. She grabbed her phone. The grin on her face said it all as she read back last night's conversation. "It wasn't a dream! She really wants to swap places with me! With me! I get to become Maddie. Madelyn Caroline...it sounds so much better than Harper Elizabeth haha!
Harper's Mom drove her to practice and she swam faster than usual. She showered afterwards and got driven to school where she floated through her day.
Maddie too was in a great mood throughout Friday. She was going out with friends again but she couldn't resist a mirror selfie to send to her sister.
'Hey Maddie! What do you think? Pretty hot huh?'
Harper heard her phone go off. The pure joy she experienced at that moment couldn't be expressed in words. The Name! The picture!
'Sooooo hot Harper!!!! God you're gorgeous! Have fun tonight!'
Maddie was wearing a super tight cream colored top, a black skirt and black ankle booties 'Thanx little sis!' 💋
'No probs big sis!' Harper text back with a 💋
Both laughed in their own rooms.
Maddie's night was long and fun but she was dragging a bit by the end of it.
Soon enough, it was Saturday morning and time to finish up.
Jean read the final readouts on 64A and 64B. She had the full printout of the text conversation between them. She could show it to the Mother to at least prove that they wanted this final result, that they were happy with the outcome. "They caused this. They wanted it so badly...it’s not my fault or the fault of the program. Perhaps we can market this in the future...refine and perfect the swapping. We could charge more in fact. Maybe we could prototype their education swap? Advance it to a maturity swap? I could use this as an advantage" Jean thought to herself as the final stages ran down preparing for the finish.
Maddie looked around her apartment "The next time I see it, it will be real and it will be mine"
Harper looked around her room "I'm so happy...I get to come back here in reality" she took one last look in the mirror and she smiled happily.
The program took them to the end. Both of them stood before a door on opposite sides of the original room.
Harper's door slid open and she stepped cautiously into the room.
The huge cavernous feeling was there, the one solid wall mirror was there. She saw she was still Maddie both below and in the reflection. She softly walked to the middle of the room.
Maddie stood nervously in front of her door. There was still a chance they wouldn't get their wish and that frightened her more than anything else. The door slid open.
Bright light blinded her momentarily but as she stepped blinking in, she saw her sister and she rushed forward.
"Ohmygosh!" Harper said seeing herself step in; Harper stepped in...Maddie as Harper and her heart filled with joy.
They ran into each other's arms and hugged each other tightly. Maddie was still Harper. Bigger and stronger and she was so excited, she lifted her sister off the ground briefly.
"Ohmygosh! I've missed seeing you so much! I'm so glad you still look like me!" Maddie laughed
"Oh I know!" Harper replied happily, wiping tears of joy from her eyes.
"HARPER ELIZABETH AND MADELYN CAROLINE" The voice thundered out making both of them jump.
"The program has come to an end. What you do from this point on is of your own free will. You have come to the most crucial and critical decision you shall ever have to make"
They looked at each other, anticipation building.
"Return to your original bodies or continue on as each other permanently"
Maddie's heart skipped a beat hearing it out loud. Harper felt faint. She grabbed her sister's hands just to stay up.
"The program will restore you to your original physical form. At that point you will have two paths. If you wish to remain as your original self, you will turn and leave the room via the doors you entered.
However, if you choose to...complete your journey as the other, you will step through the mirror. The decision is yours"
Before they could say anything, they began to change back.
"AH!" Harper yipped, feeling herself growing "No!"
"No it's okay! We have to look like we originally did before we can override it" Madelyn explained.
Harper looked confused for a moment. She looked down and saw her breasts growing back. The hair dangling in her eyes was darker. "Oh! Oh you're right!" She said in a deeper voice.
Maddie was shrinking. Everything on her was getting smaller as Harper grew larger.
It was very fast. No real time to reflect as they essentially reset.
Maddie looked to the mirror and gasped. The mirror image hadn't changed, it was still Harper looking back at her. But looking down made her think she was back to being little Maddie.
Harper was grumbling watching her sister shrink down shorter than her again "not fair" she pouted petulant.
"No Harper look!" Maddie said in her high voice pointing to the mirror.
Harper turned her head, did a double take and then jumped to face the mirror full on. Maddie looked back at her. "Oh!" She giggled "I get it now!"
Maddie nodded "Yeah. We step through and we become the image in the mirror or we walk out as ourselves"
Their clothes changed on them and in their mirror images. They were wearing simple black shorts and white tank tops.
"We're stepping through right?" Harper asked nervously "I want to be Maddie"
"Absolutely! I want to be Harper" Maddie replied.
"I don't think I could go back to being my...Harper" Harper said. "I think something like, already happened to us anyway"
Maddie nodded "Well…" she stammered and blushed "I already have your while education"
Harper gasped "I thought that was just part of the program! It wouldn't be fair for me to be in 6th grade with college...but...but I think you're right"
Maddie just nodded "I just felt different. I understood it. It was all just there. Your maturity came to me too over the course of the week. I just felt older, more naturally fit to be, well, to be your age. 21"
"And I just don't feel that way anymore. I had my doubts and worries. That's why I wanted to do this in the first place. But then, you know, when I finally admitted that I liked being you more, I really just let it happen and I felt more like a kid again"
"Because essentially you became a kid again" Maddie said. "Thanks for texting me" she blushed again.
Now Harper blushed "I have never been more scared in my life!"
"You?! Me too!" Maddie laughed "I could barely breathe! I was going back and forth not knowing if I should push it or hint at what I was feeling"
"I dropped my phone, like, I couldn't see straight, I was so nervous. Especially that text where I called you Harper!" Harper admitted.
"Ohmygosh that made me melt!" Maddie confessed. "That was when I realized you wanted to really swap too! The unbridled joy I felt...that text of just simply yes"
They hugged again. This time Harper was the bigger of the two of them and she felt her huge boobs squished up against Maddie.
"One last time huh?" Maddie said as they broke apart.
Harper nodded "Yep...last night I'm bigger than you"
"Last time you're older than me" Maddie added.
"I can’t wait to really be you" Harper replied blushing "I want you to be me so much"
Maddie smiled, trying to hold it down, pursing her lips.
"Why didn't I ever see it before? We should be reversed...it’s so obvious!" Harper added.
"Well you know I thought that" Maddie said, raising her eyebrows in an "I told you so" look on her face. "I just knew it. I thought about it too many times for it to be coincidental. But this...this finally made it first a possibility and now, our reality"
"I can’t wait!" Harper bounced acting very much like a 12 year old in a 21 year old body.
"I can’t believe I'm saying this" Maddie composed herself "Are you ready to physically switch bodies with me?" She was smiling wildly as she finished.
"Yes I am, little sis" Harper said.
"Not for very much longer big sis" Maddie laughed looking up.
They both now faced the mirror and their mirror images. Harper stood before Maddie and Maddie looked directly into an image of Harper.
Maddie liked her lips as she moved up closer to the mirror. She felt static electricity crackle over her. She heard popping sounds in her ears.
Maddie scooted her bare foot up to the mirror, just so close to touching it but not. Her small sky blue toes beneath her, reversed and reflected back were Harper's long toes with manicured burgundy nails. As she lifted just her big toe on the other side, the burgundy polished big toe lifted.
Harper now slid her foot forward and imitated her sister, wiggling her long toes and watching the mirror image imitating her but with small sky blue painted toes.
"Let’s do this" Maddie said.
Harper nodded. She lifted her left foot and brought it to the barrier. It hovered there as Maddie lifted her right foot "3,2,1, GO!" Maddie said.
Behind the scenes, the readouts of 64A and 64B began to change. The master listing for both went blank before coming back and beginning to change. 64As age began to roll back 21...20...19… As her birthday changed on the display: February 9 2001 blinked to May 5 2010.
64B changed as well, rolling up 12...13...14 as her birthday changed, reversing the last 2 numbers 10 to 01...May 5 2001… February 9 2001.
"Oh that tickles!" Harper yipped as her toes hit the barrier. The reflection fuzzed out as Maddie's foot simultaneously hit the barrier.
"Oooo!" Maddie cooed and giggled. The barrier remained but it was no longer a mirror, instead it was a static wall to pass through.
The crackling sound popped loudly, seering through them. The static cleared and they had a clear view now.
Maddie gasped loudly as they saw what was occurring.
Maddie felt a sudden loosening around her toes and the ball of her foot.
The suit she was wearing in reality was now expanding, allowing her body to grow to change into what it was now reading as her correct dimensions and proportions.
What Maddie saw was her toes lengthening, widening, growing and changing into Harper's toes. Her nails were a perfectly manicured burgundy color. She screamed in joy "AAAAAAAAHHHHHHH!!!!!!!"
Harper felt pressure on her toes and ball of her foot, a constricting and pressing as her toes shrank and her foot narrowed.
Her suit reprogrammed and now wouldn't stop until everything contained within it was made into the proper size and shape.
Harper saw her toes squeeze in. They shrank down shorter, the ends curled as her nails thinned and changed topped by sky blue polish instead of dark burgundy. She squealed a sound of ecstasy "YYYYEEESZZSS!!!!"
The changes continued down. Maddie's foot widened as Harper's narrowed. Sides, arches, and heels all changing size and shape and skin tone.
Both girls put their foot down simultaneously on the other side of the barrier defiantly. They looked at each other. The changes included their right ankles and part of their calves.
Maddie nodded "Do you see that?! It's working! It's absolutely going to happen!"
"What are we waiting for?! I want to be you! EEEEEEEEEE!!!!!" Harper squealed.
Maddie put her left hand out and Harper grabbed it with her right. They squeezed each other's hand but then Maddie turned towards Harper and put out her other hand.
Harper took it too and they adjusted themselves to face one another, scooting up close.
On the other side of the barrier, their changed toes touched and they both giggled. "I've got an idea and you can say no but I'm thinking we hug each other and dive through as one. Together. We go through together, we come out together, squeezed together tight, feeling each other change into each other as we go through" Maddie said.
Harper's eyes widened "ohmygod I absolutely love it! We can hold each other and change in each other's arms so I can feel my boobs shrink and yours grow simultaneously! Yeah! Let's do it!"
Maddie wiggled her toes, tickling Harper's little ones and they both laughed.
Maddie took a deep breath and hugged her big sister. Harper wrapped her arms around her little sister's back. They locked eyes and with a nod and a shift in weight Maddie threw herself to the right and Harper threw herself to the left.
"Shit" Jean spat out "They’re going to overload the whole grid"
They rocked to the barrier putting all their weight on their already transformed foot. Their outside legs were the first thing to now break the line.
Maddie's right calf shrank down. The outside of her right thigh hit and Maddie felt softer. Fat started along the outside adding curve and subtracting the ropy swimming and softball muscles.
Her right hip and right shoulder hit next and the static crackled like crazy.
Harper glanced down at her new left foot "I love it!" Flashed through her mind. Her left calf rocked forward through the break line. It wavered and she watched as her skin tone and the curve of her calf muscle wavered back and forth between her own and Maddie's.
She felt the muscles tighten, loosen, and tighten back up as Maddie's sinewy muscles finally took hold along with her tan skin.
Harper leaned to the side following the momentum of them. Her left thigh and her left knee now hit and shot inward, shrinking down and in. The muscles took on newfound purpose gaining strength while losing length. Her left hip narrowed and straightened. Her left shoulder broke through now as well.
Their eyes met. Both of them pulled in their bottom lips. Slight matching sly smiles.
The right side of Maddie's head and the left side of Harper's head smacked the barrier.
Both rebounded the slightest amount as the hair at the spot of impact blossomed out changing color and texture.
Stars bloomed from their temples.
To Harper or appeared that her sister's face wavered, wobbled a bit as the skin began to change. Features moved, changing in a shockwave.
Maddie saw the same. A circle on Harper's head changed from dark brown thick hair to lighter brown thinner hair which then spread outward like a spiderweb changing all the hair on that side of her head, stretching to the crown.
Harper's skull wavered as it shrank down, changing size, really cementing her new size as the new Madelyn.
Harper's left eye reached the point. The corner pinched down, narrowing it as the brown changed to green in a wave.
They heard an odd sound, plastic scraping as their face shields rubbed together.
64A readout screen: Eyes Brown...Eyes…---
Eyes Green
Harper's eye reshaped, her eyelashes thinned, her eyebrow thinned, lightened and changed shape.
Her left ear shrank down and the outside of her cheek puffed out as more of her upper arm and left thigh and hip transformed as well.
Through her mismatched eyes, Harper watched her little sister turn into her big sister.
Maddie's hair darkened and thickened. Her skull expanded as her right eye popped. The pinched edge opened, widening her eye into big doe eyes. The green darkened to deep brown as her iris widened. Her right ear grew larger as her eyelashes thickened and her eyebrow darkened, sculpted and arched.
Her right cheek sucked in losing baby fat and sleekening out.
"MADDIE!" was yelled out but neither could tell which one of them said it.
Maddie's leg shifted, continuing her change. Her thigh and knee now changed. Her hip spread out and now, her right butt cheek ballooned out suddenly gaining mass and weight and more importantly, shifting her center of gravity.
Maddie lurched and in their embrace, they went further through.
64B eye color changed from green to brown. Her weight was steadily ticking up, her height currently read 5'5".
The corner of Harper's mouth ticked in, her lips starting to thin.
The bridge of Harper's nose narrowed then her nostril sucked in smaller as her chin and jaw weakened and shortened.
Their faces were quickly becoming each other's, their upper arms had now changed too but now, a truly monumental change started.
Their chests were smashed together in their embrace and Harper's large left breast and Maddie's tiny right breast hit the barrier and began to switch in coordination.
Maddie's swelled as Harper's shrank. A to D. D to A. Harper had been pressing her breast forward but in a heartbeat their respective positions swapped. The pressure was now coming down on her. Every inch and ounce she lost, Maddie immediately gained and now Maddie's huge breast dominated and dwarfed her sister's tiny one. Balloon and compress, reduce and enlarge.
The weight shift pulled Maddie forward. More of their faces crossed. Their noses now completely swapped. Harper's shrinking and Maddie's growing.
Their mouths and chins crossed as did the forearms.
Their other eyes swapped giving them matching sets again.
Maddie's lips plumped, her teeth grew larger and straightened out.
"HARPER!" was yelled out in a wavering voice that went deep then high.
Harper's lips thinned, her teeth shrank and went crooked. More hair changed. The other sides of their cheeks shifted.
Harper looked into her own face. Her sister simply looked like her. She recognized it as hers now.
Maddie couldn't deny the fact that Harper looked like her. Her whole body was tingling in transition. She felt softer, curvy and frankly better.
They were swapping heights as their backs slipped and popped.
The hands they had wrapped around each other went through. They had similar hands but Maddie's grew slightly larger while Harper's slid inward and grew rougher. Calluses formed from her love of softball.
Far side cheeks puffed and streamlined. The size and shape of their far side ears changed. Hair trailed up and back constantly changing as they went through.
Now gravity pulled them down. Arms squeezed as they changed. Their other shoulders dipped through and then, the far side of their chests.
Maddie started to laugh as she felt her left breast swapped in time with Harper's right breast. Once again, they danced with one another. Maddie's inflating as Harper's deflated. No space ever occurred between them. Harper's decreased as Maddie's increased. At a point, Harper went from having the larger breast, to having one of equal size to her sister and then, she had the smaller one.
Maddie's breast started out so small but grew bigger gaining, taking size away from her sister. Steadily she grew as Harper shrank. For the briefest of moments they were the same size and then Maddie eclipsed her sister, truly becoming the bigger sister and it was her larger breast that bore down and smushed Harper's tiny boob.
Their stomachs and midsections passed through followed by their outside arms and their opposite hands.
Maddie's deepening laugh filled the room and Harper started to giggle the high pitched twitter of a tween age girl in response.
They began to tumble, so entwined and now clumsy from the swapping of their heights and weights.
The readouts were going haywire as Maddie's right leg and Harper's left leg buckled.
They grabbed each other tighter and both trained their eyes back toward the barrier and their trailing legs.
Harper twisted underneath as she was now smaller and lighter. Her right ass cheek popped in suddenly and drastically bringing her hip in alongside it, narrowing and straight. She also felt the additional weight on top of her as Maddie's hip shot outward gaining Harper's lost curve.
But more weight came from the expansion of Maddie's ass.
Maddie felt a blompfh. A rapid expansion of her left cheek blooming, popping out into her new shape and size.
The changes continued down their legs. Harper's leg on the bottom was larger as they started their journey and Maddie's leg on top was narrower and thinner but as their legs rode forward through the barrier, those positions switched and flipped.
For the last time, Harper would have the larger leg. Her's narrowed and thinned underneath her sister's as it widened, plumped and grew.
Maddie's leg came to dominate. Not only on top but larger and longer.
Their thighs swapped, their knees switched, their calves flipped sizes, shapes and lengths.
Their new heights and weights locked in as their ankles changed. Nearly complete, the sister's could tell the ground was coming up on them. Their feet; Maddie's left and Harper's right rose up in the air as most of their bodies now crashed down. Their shoulders contacted the ground but their eyes remained fixated on their feet.
They could feel their feet moving against one another. Harper could still see her own foot, the last part of her original self. Her foot, bigger than her sister's, topped off by burgundy pedicured nails. Maddie's foot alongside it, still smaller, the only thing smaller on Maddie than on Harper at this point. A full size smaller. The barrier tickled the tops of their feet.
"This is it!" Maddie thought. The top of her foot widened. Her toes popped out longer and larger. Her nails changed. No longer sky blue but now burgundy and pedicured; perfect.
"Finally!" Harper thought as she watched their feet change. The tickling sensation ran over the top of her foot. She could hear a high pitched hum as her foot narrowed, softened, and tanned.
It finally shrank down just as Maddie's grew.
They exchanged feet simultaneously. Harper's toes shrank and narrowed as her nails brightened, becoming topped by sky blue polish as opposed to dark burgundy. Even though she saw burgundy toes, they were no longer her own.
The tickle ran over their heels and through the soles of their feet.
A high pitched hum rose higher and higher, a din shot out in a Soundwave. The barrier had been breached fully and the sisters collapsed to the floor still holding one another tightly.
Harper had twisted and she landed on her back. The program was over, the magic was over and Harper now saw nothing clearly. Everything was just a milky haze.
But she felt weight land on top of her "oof" she exhaled feeling crushed but the body weight quickly rolled off.
She still had her arms wrapped around her sister but she wasn't holding on as tightly. She felt Maddie squirm and she released her but Maddie still pinned her arm down.
She could hear heavy breathing. It was coming from both of them.
Harper panted trying to catch her breath now.
The vision was over. She became fully aware of just wearing a tight clinging suit. She couldn't feel her body, just the suit.
She rotated her ankle feeling the bootie stretch. She spread out her toes but again, just felt the suit.
Harper panicked as a thought occurred to her "What if it wasn't real? What if that was still just the program and we really didn't switch? What if I take off this suit and I'm still just Harper?"
She bucked and Maddie rolled off of her.
Maddie saw her foot grow, her sky blue nails turn into Harper's burgundy ones but then everything fritzed out. She unceremoniously hit the ground and saw a milky haze of nothing.
She grunted, coming untangled with her sister, trying to free her arms, trying to catch her breath. Her mind reeled and scrambled trying to catch up "What’s going on?" She thought feeling the restrictive suit just clamped to her.
No sense of real or program but to both of them, they just felt confused.
The floor was just cold concrete as both girls squirmed.
Harper reached for her head trying to find a release for her mask. Finding her cowl and her fingers probed around the back where she felt a strap but her hands and arms were numb, like they were asleep so she fumbled with the notches and straps "Mmnngg" she grunted but inside the mask, it just echoed.
Finally she felt it pop and she flipped it off sucking in a breath of cool air.
Maddie was crawling. She managed to get to her knees, heaving she rocked back sitting on her calves as she too reached up and unfastened her own mask "ohmygod" she mumbled.
Their ears perked up, both of them cocked their heads as Maddie pulled her cowl back to unleash her hair and ears and the sides of her face.
The cool air hit them. Maddie realized how hot and sweaty she was; her hair and neck were soaked.
She was watching her sister. From the back and side profile view she had, she could barely see anything "is her nose smaller?" She thought as the blue hands reached up and pulled back her hood.
Maddie's eyes slowly widened. Her heart started to pound. Harper's hair was lighter. It was wet from sweat but it looked like her hair.
Harper's hands sat at her temples blocking most of the view.
Harper tapped her temples, she tapped the outside of her cheeks. She brought her hands to her nose and ran them down to her upper lip.
Her heart started pounding, feeling her face. "My cheeks! Are they puffer? My nose! Is it...smaller?! I think it is!
Maddie froze and took in a very deep breath making her chest shake. She felt something move. Something on her chest. "Is my chest heavier?" She froze and tensed her muscles along her sides and chest.
Then, she looked down.
Even in a restrictive strapped down suit, she knew. Her breasts couldn't be contained. They were simply too big and despite the suit, she still saw the large rolling mound at the front of her suit. "Boobs! I have fricking boobs! Harper's boobs! Holy shit it worked!"
The sisters spun towards each other. They couldn't speak as they finally saw one another but they recognized. Harper looked at her sister. Shock and joy rushed through her as a smile started.
Maddie slowly nodded. Pure happiness engulfed her as she looked at her sister. She smiled about to burst.
They lunged at each other laughing, giggling and talking suddenly way too fast to be understood as they fussed over each other and hugged.
"Ohmygod it worked!" Harper yelled out in her high pitched voice. She had looked at Maddie and had seen herself.
Maddie had her face. Maddie now had big brown doe eyes. Maddie had full lips and sleek high cheekbones. Maddie had thick dark brown hair. Maddie's face was mature and adult, one showing off 21 years of age.
More importantly, she had seen the swell of Maddie's chest.
"This is it! We did it! We switched places!" Maddie squealed back.
She looked at her sister and saw her own face and hair. The light thin hair framing the face of a 12 year old girl.
Harper had the small green eyes. Harper had full chubby cheeks, a small nose and thin lips; the immature face fit for the tween she now was.
Harper immediately noticed how much bigger Maddie was than her now as she tucked into Maddie's hug.
She put her head down to the top of her big sister's chest feeling herself lifted upon her large bosom. She loved the feeling of comfort she felt as Maddie stroked her hair and just rocked a bit holding her.
Harper just wanted to curl up there.
Two technicians entered and silently began to undo all the wiring and outside packs and sensors.
Maddie and Harper watched them and each other, still very much fascinated by the sight of the other.
"Go out this door and the first door on your left is your recovery room. You can spend as long as you want in there" one of the techs said gathering up the equipment.
Maddie and Harper exchanged a look and smirked.
Standing up was another adjustment for them and Harper gasped, but in a good way, seeing that Maddie was now 5 inches taller than her.
Maddie giggled looking down at her little sister "My little sister in so many ways haha" she laughed, a smile of joy on both their faces.
They were both stiff but it was only a few steps out. Harper watched her big sister step so elegantly, her hips swaying so naturally.
They rushed into their own private room.
The door slammed shut and Harper went off "I can’t believe it's actually true! This is so freaking awesome!" She drummed her feet and hopped about.
"Oh my God I know!" Maddie added quickly. "I can’t believe it either" she took her sister by the shoulders "It's real! This is us now!"
They squealed in unison.
"I know and I couldn't be any happier!" Harper said "And this is how we're going to stay from now on! I'm Maddie from now on!"
"And that makes me Harper! Your older and more developed big sister!" Maddie laughed.
"I love it!" Harper replied enthusiastically.
Maddie undid the wrist straps and peeled her gloves off revealing her new hands. She flexed out her longer fingers and spread them out testing their width.
She gently shook her head, still disbelieving that those were actually her hands. Maddie undid the velcro.at her neck and found the main zipper.
"Whooooooo…." She let out a long breath as she unzipped the front of her top.
When the zipper reached her breasts. It hung up just so then pulled down and out she spilled.
"Whoa!" She laughed as her massive breasts spilled out of her top "Holy shit"
"Haha now you know it's real" Harper teased seeing the huge globes sway and bounce freely.
Harper had taken off her gloves and was sitting down undoing her booties.
"Damn" Maddie laughed "these things are fucking huge haha!" She grabbed them, heated them up, squeezed them together and let them fall laughing all the while.
Her hand traced over her stomach. It took effort to get her top off. She was sweaty and it was literally sticking to her upper arms.
Harper giggled and ran her fingers over her sky blue toes. She stood and unzipped revealing much less but her top slipped right off. She had to yank and pull her sister's off.
Their pants went the same way. Harper and her skinny legs were out in no time.
Maddie ended up lying on her back while her little sister rolled them off of her, they were so tight on her thighs and calves.
Finally freed, there were two showers and the sisters headed to them.
Coming back out wrapped in towels they still smiled upon seeing each other let alone their own reflections.
They swapped clothes and phones and purses before they headed out and met their Mom who gave them a funny look until they both hugged her and talked a mile a minute about how happy they were.
Harper happily got in the back seat as they drove home. She was already looking forward to her swim meet in 2 days.
The morning of the meet she awoke to a text 'Good luck little sis 💋'
'THX big sis 💋' was all she needed to reply with.
They never regretted their decision.
