Emily was 5 years younger than Elizabeth but now 28 was 17 years older which made her the responsible adult. Liz had grown up babysitting Emily and if she ever found out what had happened to her big sister and that it was her turn now; she would never live it down.

Her Dad came home and went right upstairs to change into a suit followed soon after by Carly who just winked at her as she went past and up the stairs too.

Liz ventured up after a few minutes. Her Dad said “We’re going to be out late tonight so don’t expect to still be up when we get home. We told your Aunt Emily that she could sleep in the spare room if we’re really late”

“Okay” she replied and waited until Mike left the room before she whispered huskily to Carly. “Not a word of this to my sister. I totally forgot about this until this afternoon”

“What? Are you embarrassed by the thought of having a babysitter or the fact that it’s the  baby sister you always got to watch and be bigger than?”

“Um…both okay” Elizabeth said.

“Our secret is safe with me: She wouldn’t believe me if I told her anyway, you know that” Carly replied with a smile that was a bit too smug.

“Whatever…just…behave yourself tonight”

Carly chuckled “Don’t worry Mom…I will” as she stepped into her nicest black dress. She sat back down to strap on her 4 inch open toed heels.  Even Liz had to admit that she looked gorgeous. Her hair was done up as was her make-up and the dress fit her perfectly. It showed just enough cleavage and leg.

“You look great by the way” Elizabeth said quietly.

“Thank You…It’s a great body to work with” she said as she thought “I’m going to hate giving it up in a few more days” as she checked herself out in the mirror in profile.

The doorbell rang and Carly said “Go let your sis…I mean Aunt in honey”

Elizabeth trudged down the stairs and sighed before she opened the door. Of course there stood her little sister. Now standing at least 6 inches taller than her and looking like the grown woman that she was.

“Hey squirt, how’re you doing?” Emily said as she came in.

“Good Aunt Emily, how are you?” Elizabeth said with a straight face.

“Good as I can be on a Friday night” she replied taking off her shoes and coming in.

“What do you want to do tonight?” Emily asked.

“Nothing” she thought but relied with a “I don’t know, whatever”

“I was thinking about ordering pizza and then we can watch a movie or play a game or something; whatever you want to do really”

“Okay” Liz replied as she heard Mike and Carly coming downstairs.

“Whoa…looking hot tonight sis” Emily said upon seeing her sister in her dress.

“Thanks Em”

“Thanks again for watching Carly tonight Emily” Mike said.

“It’s no problem really. My sister watched me so often when we were kids, I’m happy to repay her anytime” Emily replied as Carly and Elizabeth shot each other a nervous glance at the wording.

But they headed out and Elizabeth soon found herself at home with a babysitter. “My babysitter, my baby sister” she thought as she plopped on the couch.

“Want to play Xbox?” Emily asked.

“Sure why not?” Elizabeth replied. She sat cross legged on the floor and grabbed a controller. She usually sucked at video games but using Carly’s motor skills, she found that they were evenly matched.

Once Pizza arrived, they quit and went to the kitchen. Liz scooted back in her chair until her feet lifted up and she blushed even though Emily had no idea why.

“Your Mom and I used to play Nintendo against each other and I used to beat her all the time. I loved it because she always beat me in everything else”

Elizabeth almost said “I remember” but caught herself and instead said “Good for you; she needs to get beat at some things”

Emily laughed “That’s what I’m talking about”

“Aunt Emily…what did you think about my Mom when you were growing up?” Liz asked.

Emily smiled. “It’s complicated but I guess it always is with sisters. At times I hated her and other times, I looked up to her. I hated when she’d use her size and age and experience over me but it was also trying to catch up to her, trying to make her notice me and be proud of me that pushed me sometimes”

Elizabeth smiled and took another bite. “Was she ever too mean to you?”

“I’m sure I thought so at the time but no, she’s always been pretty good to me”

They finished up and settled in with a movie on the couch. Liz was glad it wasn’t as bad as she feared even if she was told to go to bed at 10.

She stood up and yawned and gave Emily a hug, just a little self-conscious at her flat chest coming up against her little sister’s boobs and having to stand on her tip toes to put her arms around her neck.

At the wedding, Carly held Mike’s hand throughout the ceremony and then as they walked to the hall. They found their seats and sat next to each other. He put his arm around her shoulder and rested his hand on her leg as they listened to toasts.

“Can you get me a drink?” Carly asked.

“Sure Liz…what do you want?” Mike replied.

She had seen her Mom drink a few different mixed drinks over the years and she tried to think of the names of them “Do you want a Long Island Ice Tea?” he asked.

“Sure”

It was stronger than the wine by a load and she decided that one was enough as they ate their dinner. But it did help her dancing skills the rest of the night even if she did have to take off her shoes to dance.

Carly had a great time that night. It was well after midnight before she even looked at the time. She put her shoes back on to get back to the car and they talked and laughed about the night during the drive home.

Once in, they found the house quiet so they snuck up the stairs. Mike peeked in a saw his daughter sleeping soundly while Carly opened the guest bedroom door. She saw her Aunt covered up and out like a light.

Carly undressed in front of Mike thinking “He’s not my Dad at this moment; he can see this…calm down…he’s used to this and he sees his wife. He’d be upset if I didn’t”

“I’m going to shower” she announced and headed into the bathroom. She was extremely relieved to find him sleeping when she got back out. She put on her purple nightgown for the first time since the swap and climbed into bed behind him.

Elizabeth was up first on Saturday morning. She had basketball practice at 11 and hoped someone would be up to drive her there.

But with no one else up, she was free to climb on the counter to get her bowl for her cereal. She was watching TV and reading a book for homework when Emily came down.

“Hey Aunt Emily” she said without thinking it odd “Did you sleep ok last night”

“I did kiddo Thanks for asking” Emily said.

“Every night it seems more natural and normal to be Carly” she thought going back to her book as Emily made coffee the same way her Mom did “The same way I do” she corrected herself in her head.

Her Dad came down at 10:30 and found her in her basketball shorts, jersey and slides with her bag packed. “Just in time Dad-o to take me to practice”

“Yep…let’s go” he said as they headed out to his car but she was still relegated to the passenger seat.

She hopped out and went in to change shoes as Mike parked the car.

Carly came down and found Emily sitting on the couch “Hey sis…how was last night?” Emily asked.

“Oh, it was good. We had a great time; how was Carly?”

“She was fine…kind of quiet last night but good as could be”

“She’s been a little more reserved lately but luckily we haven’t had too many emotional outbursts and back talk” Carly said as she sat down next to Emily. She was a bit taller and older than her Aunt now and wanted to enjoy it.

“I know…I remember being that age” Emily said.

“We all think we do but it’s tough on a kid” Carly said. “I know”

“We were all there…just wait until she’s a real teenager sis” Emily said.

“If only…if only she could stay as me until she was a teenager” Carly thought. As the week went along, she had found it very easy to think of herself as Elizabeth. Being Carly was there, but it seemed further and further away with each day. She wondered if they didn’t swap back on Tuesday if she would forget being Carly all together and Elizabeth would forget it all too. She wondered if it was possible. She wouldn’t mind it in all honesty.
She liked being an adult and she could tell that being a kid was definitely growing on Liz.

“She seems fine with it now” she thought “I wonder if she might be up for extending it a little bit longer if we both agree to it”

Emily left and Carly was alone while her husband and daughter were at practice. She saw the backpack lying by the table. She kicked at it with her big toe and thought “Glad I don’t have any homework this weekend”

She went upstairs and put on some sweats and a t-shirt and started reading a book for pure pleasure.

That night, Mike went out to a game with his friends leaving Elizabeth and Carly home together. There was plenty of left over pizza from the previous night so they warmed it up for dinner.

“So” Carly began, ”Tell me how you feel…honestly…about being a kid again”

Elizabeth smirked and sat back “Ok, I’ll admit it that I like it”

“I knew it. I could see it in your face that you were having a good time but didn’t want to show it” Carly said.

“So how do you like being an adult?” Elizabeth came back to her.

“Are you kidding? I love it. You said it yourself; I’m an adult” Carly said. “Suddenly I’m the one with freedom and yeah responsibility, but I love it…I really do”

“So what have we learned? We still have like two more full days like this. Have we learned whatever lesson we were supposed to?”

Carly smirked and leaned forward; her breasts hit the table “You learned that it’s not easy being a kid”

“I learned it’s not easy being short too” Elizabeth admitted.

“And I learned what a mother’s love feels like and that it’s not easy worrying about kids” Carly conceded.

The pizza was done so Carly got up to get it out for them. She put down a holder to protect the table and they started eating.

“I have one question though” Carly added. “You were already slipping up and calling me Mom on the first night. Do you think that as the week has gone one, that you find yourself thinking of yourself more and more as me? Like really me…like you were never Elizabeth at all”

“I don’t know what you’re going for?” Elizabeth said slowly.

“What I mean is; as the week has gone on I feel more and more like being Carly was a really long time ago: Like it was even just a dream. I’m comfortable as Liz and as your Mom and it’s getting harder and harder to think like Carly and pull myself back to her”

“I see. I know what you’re talking about. It is hard to keep it straight as the week goes on. I catch myself sometimes slipping more and more into being Carly all the time. I know I’ve lost some things. Words are gone…some knowledge and thoughts that I guess that you have now instead of me. You got them along with my body”

“Would you consider staying as me for a longer period of time?” Carly asked straight up.

“What? Now I don’t…” Elizabeth began.

“Hear me out please” Carly began. “Just out of curiosity would you do it?”

“This is what got me in trouble in the first place” Liz retorted.

“I just feel like I’m not done yet; like there’s still some things I need to see and try as you” Carly said.

“Like what?! You want to have my period for me?” Elizabeth said in reply. “No…I can’t go along with this Mom; Ugh…why do I keep doing that? I mean Carly!” She stood up “Look it’s already gotten bad enough for me. I’m going to be honest here. I’m already a little too comfortable as you. I get up in the morning and the first thing I think about is school. I see you and I think: Mom. I see my husband…the love of my life and I think he’s my Dad. I’m no longer attracted to him because I only see him as my Dad. I can’t keep going like this or I will get lost as you and end up being you permanently”

“I understand your point Carly” Carly said. “I just…I was just hoping for a few more weeks…you know, maybe a month as each other”

“I know it can be really cool to find yourself as an adult. You get to tell me what to do instead of the other way around. You’ve got an adult body and most of an adult mind right now and if you’re a bit afraid of giving that up and returning to being just another 11 year old kid, I understand but I’m afraid that if we spend any longer in these bodies, we’ll never swap back and we’ll forget who were really are”

Elizabeth continued “You can’t stay as me. As comfortable it is and as fun as it is, you’re not me and I’m not you. It would be wrong for everybody involved in the long run. I really like being you Carly and yes part of me likes being a kid, in the end, it’s not fair to take your childhood”

Carly nodded “You’re right: I’ve just had such a good time this week. I love being you and…well we have to see what Tuesday morning brings”

“Yeah, we’re just assuming that we’re going to swap back because we said we would but this is some magic that is out of our hands and you never know, maybe we don’t change back.
Maybe we just slip further and further into our new bodies and minds and realities” Elizabeth conceded.

She sat back down and put her hands up “Maybe this week was just the warm up and come Tuesday, it’s just another day. We sit here across from each other waiting for something to start tingling and nothing happens; what do we do then”

“Then I go to work and you go to school and eventually we do forget who were and become who we are. I stay you and become Elizabeth and you stay me and become Carly; I stay as your Mom and you continue to grow up as my daughter”

They finished their pizza but didn’t say much after that.

Sunday came and the whole family worked around the house and yard, Elizabeth took her directions and got bossed around by both of the adults. Carly’s back and knees were aching by the time they were done.

Monday had both of them on edge, not sure of what the coming day would bring. Part of Carly still hoped that she wouldn’t switch back and she would just fully become Liz while Liz was pulling much more for a swap back. Both went through their routines and days at school and work.

Carly came home and made dinner as Elizabeth finished her homework. They kept casting glances at the other. Elizabeth thinking “Will that be my body again tomorrow?”

Carly settled on the couch after dinner and painted her toe nails. She took her time and made sure they were done very well. She put on a double coat of red along with a clear coat on top blowing on her toes to dry them.

Elizabeth spent most of the night in her room, taking in the sight of it but also wanting to not be sleeping in here come tomorrow night. “I don’t think I’ve ever wanted to go to work more than I want to tomorrow”

At six o’clock Tuesday morning, the alarm went off and Carly’s heart jumped. Mike got up and started his routine while Carly was slow to get up “This is silly, time waits for no one. If I turn back into myself, I do and if I stay well, then, I stay and it was meant to be”

She got out of bed and plodded across the hall to her daughter’s room and opened the door “Carly…time to get up”

“Mom, I…” she sat up, “yeah, uh, sure, I’m up” Elizabeth sat up and threw off her covers, swinging her legs off the edge. She looked down at her small feet swinging back and forth above the floor “Get up” she told herself as she jumped down and felt her feet hit the floor. She looked down at her legs; she was wearing blue shorts and a big yellow t-shirt.

She had heard her Mother’s heavy footsteps going down the stairs. By the time she got down to the kitchen, she saw her standing by the Keurig brewing her coffee. Elizabeth caught a glimpse of Carly’s feet “Nice job with your nails…I like them”

Carly had her toes rolled up and her heel up but now she lowered it and lifted her toes up and out. She wiggled them up and down “Thanks, I just thought, it would be pretty”

“I never did them enough” Elizabeth admitted. “I see you’re wearing the purple nightgown this morning”

“Um yeah” Carly bit her full lip “I just thought it might be fitting to have it on since you uh…”

“I know and you’re right; it is fitting…fitting your body currently” Elizabeth joked.

Carly looked down and shyly put her right foot on top of her left “Do you want a bowl for some cereal honey?” she asked.

“I’m not hungry to tell you the truth” Elizabeth admitted. She sat down at the table though across from Carly and the two of them just looked at the other. They took in the other’s face as they looked at that moment.

Mike came down the stairs and looked at the two of them “Something up you two?”

“Why do you ask?” Carly said a bit too fast.

“You two just look like you’re up to something”

“That’s silly Dad” Elizabeth said with a laugh. Mike ruffled her hair and kissed her on top of the head then leaned down to kiss Carly on the lips.

“Bye Honey” she said simply “Have a good day”

Mike smiled back over his shoulder and went out the door with still no idea of what was behind him.

Once they were alone, Elizabeth smiled; a touch of sadness in her eyes as she looked across the table. “You’re a good Mom”

“So are you” Carly said in return.

Elizabeth sat back and put her feet up in the bottom rung of the chair. Neither remembered the exact moment when the change had started but it seemed like it was getting too late.

“Maybe it passed us by” Carly said trying to sound upset.

Elizabeth swallowed hard and shook her head “No, we just have to be patient. It’s going to start any second now…it has to”

She spread her fingers out and watched them like a hawk but nothing was changing. Her fingers weren’t growing or even her nails. “Come on…we have to change back, we just have to”

Carly looked at the clock and saw that it was 6:45. Usually the time they headed back upstairs to start getting ready; she knew it had already started before this time a week ago. She shut her eyes tight and saw a flood of memories coming in. She saw a church and a crowd of people. She focused on the front of the church and saw Mike standing there in a tuxedo “Am I seeing my wedding as it happened? Am I the one participating in it?! Is this the start of my full conversion in to Elizabeth? Am I now really Elizabeth?”

The memory started up until she heard a cry come from across the table. “What is it Carly?” she said.

“I was trying to picture my wedding and I couldn’t do it” Elizabeth said tearfully. “It’s gone. My memory of my own wedding is gone. And then I tried to remember and recreate the day I gave birth to you and I can’t do it. It’s gone too. My mind seems to be fading and changing into yours. I try to think back to my earliest memory and all I see is our TV showing Toy Story while the dog knocks me over”

“But that happened to me?” Carly said quietly. She tried to remember it but now in her mind it played out differently. Now she saw herself rushing over and shooing the dog away and comforting her daughter. “But there’s no way I could see that scene like that” she thought “unless…”

She stood up and walked around the table and embraced her daughter “It’s alright Carly” she said as Elizabeth stood up. They embraced tightly and held on.

When the two of them touched, it was a very tight embrace. Their toes touched along with their legs, their stomachs, chests, arms, hands and heads. Just when it seemed that every last bit of Elizabeth had transferred over; Carly got a strange feeling. A tingling sensation rushed through her body and she pushed herself back.

Elizabeth felt it too. Her eyes were wide and her mouth was hanging open “Mom” she said hesitantly.

“Carly” she responded.

Elizabeth laughed nervously “I mean Carly”

Carly pursed her lips “Hey Mom…I think it’s starting again” She held out her hands and said “Look at my fingers” Her nails pulled down and came even with her fingertips just before those fingers began to slim and shrink down shorter to palms that had already shrank down and smoothed back into the hands of a girl. “I’m going back…I’m going to be a kid again”

“You’re going to be you again and I’m going to be me again” Elizabeth finished. “I know you really liked being me but…”

“…but it’s not right that I should be you and you have to be me” Carly finished up. They both smiled and nodded at each other. “I am going to miss this though” Carly added.

Carly’s hands had shrunk back down and now she looked all the way down to the ground. She arched her foot up and watched as her soles smoothed and her feet narrowed. Her heels shuddered and came in. She had all her weight and balance up on the ball of her foot which suddenly narrowed and she slipped forward.  Catching herself, she refocused on her shrinking toes.

She watched as they thinned and got smaller and reshaped themselves back to their original form. Her nail polish vanished and she lowered her smaller foot back down flat. She bounced up and down a time or two as her legs began to dwindle.

Elizabeth swallowed and watched her fingers begin to grow. “Oh Thank God” she huffed. “My Body…my body is coming back” Her fingernails grew out longer as well as her fingers. They thickened as did her palms; veins and lines came back on her skin.

Elizabeth looked down now too; she pointed her small toes inward just as they began to grow longer and larger and wider. Her toe nails widened and red polish appeared on them “So our last week does matter to both of us”

“Are you going to keep them painted now Mom?” Carly asked “I think they look better painted”

“For you…sure I’ll keep them painted” Elizabeth said watching the rest of her feet return to size. Her soles thickened as did her heels as her feet widened and grew back.

Now Elizabeth began to grow taller again. She had spent a week at just a hair shy of 5 feet tall and now she began to get her height back as her legs lengthened and started to regain their curves. “This feels so good” she said, her voice still high and sounding like Carly.

“Yeah…it does feel alright” Carly echoed as she began to shrink down in height. Her legs were getting skinny and losing the mature look of Elizabeth’s legs. Her calves smoothed and her thighs trimmed and pared down. “I didn’t realize how heavy you are Mom, it takes effort to be you and have your body”

“Hey! Who you calling heavy?” Elizabeth called out as her thighs plumped and rounded. They filled out as her calf muscles bulged as they grew and her knees expanded back to size and shape.

“No, not like that it’s just I’ve been used to being your size and having your body and now I already feel just so light” She looked down “But this just looks weird; I’ve got your top and my legs look so skinny; like chicken legs”

Carly’s ass began to deflate and flatten. Her hips shot inward suddenly making her lunge forward to adjust her balance “Whoa! I need a little bit of warning before something like that happens”

Elizabeth’s hips slowly spread out wider with maturity. As they went, her ass began to inflate and round off. Mass filled in and her tiny shorts began to strain to keep up with them. “These are so tight” she said pulling at them to try and gain some relief.

Her waist and stomach spread out and grew back to size and softened up as more and more of her body returned to her. “Never thought I’d be happy to see my stomach but I am”

Carly’s back tightened and pulled in, shrinking her even further down. Her stomach and waist shrank and her arms shortened and thinned out greatly. The nightgown was hanging down for the most part and she actually looked quite silly still possessing her Mom’s large breasts.

They sat like a shelf in front of her until a quick quiver of them signaled their retreat. They clenched on their own and began to shrink down, getting progressively smaller and smaller until nothing remained and Carly had the body of a girl once more.

Elizabeth’s arms lengthened and her upper arms filled out making the sleeves of her yellow t-shirt tight. “I wore this one because it looked the biggest; I hope it doesn’t rip” she said as her chest muscles tightened.

Her back spread and her spine lengthened back out raising her back up to her full height once again. She looked down and saw that Carly’s body was back to normal but she was still missing two large assets.

Then she felt a renewed sensitivity in her nipples as they puffed up suddenly, peeking out against the fabric as her breasts began to grow rapidly outward. Mass built up, flesh expanded and gave way as she regained her large breasts. They made their way steadily outward and upward as weight increased bringing a familiar sensitivity that she had feared was lost until they were back to their original size.

Elizabeth cupped them through the taut fabric and ran her hands around the circumference of them. As she looked down, she saw her own body below her again and she had to lean further out to see her toes which seemed so far away now.

The two of them locked eyes and Elizabeth smiled a crooked smile. She still saw her head on her daughter’s body but that soon began to change as Carly’s face began to alter itself back to what it should be.

Carly’s hands came up tentatively and touched her cheeks as her skin tightened with youthful vigor and her cheeks rose up and became much rounder. She smiled now too at the thought of having her face back. “It feels good to be home now…home in my own body again”

Her chin and jaw pulled inward and her mouth began to get smaller. Her lips thinned and her teeth shrank down. Her nose pulled back and thinned as well as her ears shrinking down. Her forehead narrowed along with her eyes, which flashed from brown back to their original blue. She felt her hair hit her shoulders and as she looked down at it, it loosened and lightened in color from brown to strawberry blonde again.

“I don’t know if I’ll ever see the world the same now that I’ve seen it through your eyes” Elizabeth admitted as her chin and jaw strengthened and jutted forward. Her cheeks drew longer and her lips plumped over a growing mouth and expanding teeth. Her nose filled back in and her blue eyes changed back to brown and widened.

Her ears shifted and grew as her forehead shifted up. Her hair pulled up and darkened to her natural brown as her part reversed sides. Elizabeth exhaled “Carly…we’re back” she said relieved.

Carly smiled at hearing her Mom’s voice coming from her Mom again and no longer being her speaking voice. “I hope I end up looking like you though when I do get bigger” Carly admitted, hearing her own voice once again.

“I hope you do too but you’re you…not me, so I hope there’s enough difference for us too” Elizabeth added. She put her arms out and flexed her fingers and rose up on her tip toes.
“It was nice to get a taste of what is coming for me” Carly said.

“And I’ll admit it was nice to relive my past to some degree. I do feel like I know what you’re going through better than any other Mom out there” Elizabeth admitted. “But we also have to get our butts in gear if we don’t want to be late”

“Oh Man…I actually kind of want to go to school today now that I’m back to being me. I did miss my friends” Carly said. She shifted and felt the purple nightgown sway on her. “It’s so weird that this fit me a few minutes ago” she said holding out the nightgown “And now it’s huge on me”

“It’s amazing what a few inches and pounds can do for you” Elizabeth said as she turned on her heel and headed for the stairs. “Maturity brings many changes…I’d already forgotten how my body moves walking around as you last week”

Carly was right on her heels “Out of my way old lady” she said elbowing her way past her Mom and taking the stairs two at a time while giggling and laughing the whole way.

Elizabeth just shook her head as she made her way to her bedroom and her bathroom. She peeled off her daughter’s tight clothes and caught a glimpse of her naked body. “Thank God you’re all back” she murmured as she touched her breasts and stomach and thighs. A shower had never felt better to her aching body. “I guess changing shape and size like that takes a lot out of you” she laughed. “I mean, I was pretty small this morning and now I suppose I should ache a little bit growing like I did”

Elizabeth frankly couldn’t wipe the smile off her face as she did her own hair and put on make-up and got dressed. “I don’t know if I missed wearing heels or not…” she thought as she wedged her feet into a pair of black pumps to match her black and white dress she was wearing.

Carly was already downstairs waiting by the door. Her routine had greatly simplified being back as a kid again. A quick shower and brushing her teeth and hair before throwing on a pair of jeans, sneakers and a sweatshirt: She smiled seeing her Mom come down the stairs angling her feet in the heels she no longer had to wear. But secretly, she looked forward to a day when she could wear them again.

“You ready kiddo?” Elizabeth asked.

“You sure you remember how to drive…I think I could do it still today if you want me to?” Carly said with a laugh but an eager look on her face.

“No thanks…I’ll take it”

Being back in their respective places and worlds felt like slipping into an old comfortable shoe. They didn’t miss a beat but yet, both of them found themselves thinking to what they could be doing at the other’s life when they checked a clock.

Elizabeth knew Carly was changing classes and on her way to Spanish the one time while Carly thought about the 11 o’clock meeting her Mom was attending in her place.

That night, both were exhausted from their day and their week, but Elizabeth made sure she tapped her husband on the shoulder when he crawled into bed. She gave him the wink and smile that he knew meant they were going to have some fun and it never felt better to her.

“Of all the things I missed last week…” she thought as a smile of contentment crossed her lips. “Glad to be back…”
