Amber Richards leaned over the kitchen counter and read the mail that had arrived for her that afternoon. She knew that she should be happy and looking forward to college next year but the expectations and increased demands were just stressing her out. There were letters from three different top universities with her name on them waiting to be opened but all she could do was look across the room at her younger sister Jillian and watch her play.

Watching Jillian play with a couple of La-La-Loopsy dolls and be perfectly content frankly made Amber a bit envious. She looked at her back pack next to the dining room table leg and saw it bulging with homework and Amber simply shook her head. “It was all so simpler back when I was just a little kid” she thought.

Amber ran her fingers through her long brown hair and put her elbows down on the counter. Keeping her hands on her cheeks, she watched Jillian play away in her own little world.
After a few minutes, Jillian looked over at her big sister and said “Do you want to play Amber?”

Amber smiled and nodded “I would love to” she said and she started to walk over to where Jillian sat on the floor.

“We could play house” Jillian said as Amber eased her frame down to her knees.

Amber rocked back and sat on her heels and said “Okay…but I’ve got a great idea. Why don’t we switch it up a little bit tonight?”

Jillian tilted her head and replied “How?”

“Well” Amber smiled “Tonight how about I get to play as the little sister and you get to be the teenager”

“Awesome” Jillian replied enthusiastically “That will be cool”

Amber put her hand up before Jillian could hop up and run off “But if you want to play that way” she began “We have to play a different game first”

“What game do we have to play?” Jillian asked as she sat back down hard and swatted at her flyaway hair in front of her face.

“Well if you want it to be realistic; I have to turn you into a teenager and me into a little kid” Amber said.

“You can’t do that Amber; you’re just joking with me” Jillian said.

“No I’m not” Amber said as she swung her legs around and sat crisscrossed on the floor. “First of all you have to sit like me”

Jillian crinkled her nose and brow and thought Amber was making fun of her but after a second, she crisscrossed her legs too.

“Okay, now let’s scoot together real close so we can touch” Amber sat as she inched forward.

Amber picked at the knee of her black leggings as their knees came together. Amber was wearing thick white socks but she could feel it when their toes touched as Jillian gave her bare toes a quick wiggle as they neared each other.

“Now we need to hold hands” Amber said as she put her hands out and Jillian took them. She dropped their hands down to rest on their legs between them but held onto her sister’s small hands tightly.

“Okay…so we’re going to play a game that I guess we can call transfer” Amber said with her heart racing just a bit.

“Transfer? What kind of name is that?” Jillian asked in a tone that only a six year old could truly manage.

Amber smiled “Transfer…I transfer some of my age to you. So you get a little bit older and I get a little bit younger”

Jillian smiled an awkward and shy smile in return and let out a really long “Okay”

“Just look me in the eyes…staring contest” Their eyes met and locked, Amber could see a smile on Jillian’s face and could detect one on her own as she said “Transfer one year of my age to my sister Jillian so that she is seven and I am seventeen”

Jillian shivered and began to grow. She felt the shiver and gave into it but she kept her eyes locked with her big sister. She grew two inches as she increased in age. Her features matured just a bit but it was enough for Amber to notice and she smiled even wider than before.

Jillian didn’t see much difference in her sister and told her so “You don’t look any different Amber…are you just making fun of me?”

Amber really didn’t change much in going from 18 down to 17 but she did feel a bit different. As she took in a deep breath, she realized that her bra was a bit loose and if she thought about the classes she had been taking in her senior year; they were gone.

Amber shook her head back and forth “No I am not picking on you or making fun of you…you really are a year older now and I’m a year younger. It’s just that since it wasn’t a really big jump…it’s not that noticeable. Here: We’ll do it again, but this time we’re going to go for two years”

Amber gripped her sister’s hands and said “Look me in the eyes again Jillian…good…now; transfer two years of my age to my sister Jillian so that she is nine and I am fifteen”

This time Jillian really felt a shiver run up her spine. She shook all over and said “Whoa” out loud. She felt her toes and knees press up against her sister’s legs and feet as she grew five inches taller to 4’8” and put on weight as well. Her fingers twitched while being held as her hands grew.

She saw Amber smiling again as she felt a twitching in her face. “What?” she managed to ask her sister in confusion. She stared at Amber and realized that something was different about her big sister…her face looked different.

Amber also felt a shiver of cold wash over her as she finished talking. Her shoulders shuddered as she now lost 2 inches in height shrinking down from 5’7” to 5’5”. Amber’s arms and legs slimmed a bit as she lost two years of maturity and development, the gap in her bra increased as her breasts decreased in size.

Amber could see the confusion in her sister’s face; a face that looked older and knew that her own face would look three years younger now. She knew what she had looked like as a freshman and was sure it was a bit of a shock to Jillian. “It’s okay Jillian…I’m 15 now again” she said, her voice slightly higher but still quite deep.

Amber broke their grip and brought her hands up to her cheeks. They seemed fuller and she could feel a few pimples broken out. She stood up and noticed how loose her clothes were fitting her. She picked at the fabric of her leggings on her thighs. It came up easily and plucked down as she released it. Amber giggled quickly as she bent her knees back and forth. Her white shirt felt big on her and she raised her arms up to see it flutter a bit.

Jillian slowly got to her feet, realizing that she was much taller than she had been when she sat down. She was wearing a pink nightgown that had come down to her knees, but was now half way up her thighs. The arms were tight and pinching a bit. “What’s happening Amber? Why are you shorter? Why am I bigger?” she said in a shaky voice.  

Amber took her sister by the hands again “Just relax…you’re going to keep getting bigger until you’re eighteen and I’m going to continue getting younger until I’m six”

“But why do you want to do that?” Jillian asked.

“I just want to…that’s all. Why…do you want to quit and go back to being six?” Amber asked.

Jillian thought for just a brief second before she said “No; I want to keep going”

“Well then, let’s keep going then” Amber sat as she sat back down crossing her legs as she went.

Jillian also lowered herself down with a smile on her face. She sat and crossed her legs and brought her feet back out until they touched Amber’s again. She tucked a few strands of her light brown hair behind her ears and she nodded as she put her hands out for Amber to take them.

Amber now smiled, it was a particularly wry smile as she said “You realize what’s going to happen if I go with three years now don’t you?”

Jillian quickly did the math and smiled in return “Twins”

“Yep…but just for a bit” Amber said as she gripped her sister’s hands tight. She cleared her throat, stared her sister in the eyes and said “transfer three years of my age to my sister Jillian so that she is twelve and I am twelve”

Amber smiled and said “Here we go…”

Amber began to shrink before Jillian’s eyes. She watched as the shoulders of Amber’s shirt rose up slightly as Amber got smaller. Amber saw the ends of her sleeves bunch up at her wrists as her arms and hands became smaller. With a shudder across her back, her chest narrowed and her breasts almost became non-existent. Her hips narrowed and her legs slimmed greatly. Her thighs lost most of their mass and became skinny. Her legs shrank down as she lost several inches down to 5’1” and even her feet shrank smaller inside her heavy socks. But Amber smiled the whole time.

Jillian too was smiling broadly at what she was seeing and feeling. She again felt her knees press against her sister’s legs as she began to grow taller and taller. Her feet grew several sizes as well. Even though her legs were still quite skinny, they were bigger and heavier than ever before as she was now twice the age she had started at. She felt a tingle on her chest and shuddered it away as her body grew larger. Her hair grew longer and got a bit darker as it got thicker. Her face matured as she watched her sister’s turn younger. “She looks like a kid” she thought watching Amber’s face lose years. Her acne disappeared again as she passed back to the beginning of puberty.

“Amber” Jillian said hesitantly in a deeper voice.

“It’s still okay Jillian” Amber said as her voice pitched higher still. “Stand up with me”

As they stood, Jillian’s look of shock was indescribable as she slowly realized that she was now taller than Amber. It was only by an inch, but it didn’t matter “I’m taller than you!” she shouted out.

Amber smiled and nodded “Congratulations” she said to her sister. “We’re the same age right now…we’re both twelve years old…isn’t that awesome” Amber said as she became more enthusiastic as her age diminished.

Jillian jumped up and down in her excitement “Yeah, this is awesome…I feel great” she said as she swept her arms forward. <RRRIIIPPP> “Oops” she said as the sleeve of her right arm tore down the back.

“We need to get you some different clothes” Amber said and she ran for the stairs. She had to grab the waistband of her black leggings to keep them up as she climbed the stairs to her room.

Jillian was right on her heels “Wait for me…I want to pick them out” she yelled.

As Jillian sorted through Amber’s closet and drawers, Amber sat on the edge of her bed “I guess when this is over, we’ll have to switch rooms” she said.

“Uh…yeah…I guess we will” Jillian said over her shoulder to her sister.

Amber also thought to herself “I can’t remember high school classes anymore. I wonder if Jillian has thought about anything besides what’s going on to her”

Jillian hadn’t thought about it, but it was undeniable that her vocabulary had expanded along with her body. “This skirt is so cool…I’ve always liked it on you…can I wear it?”

Amber just nodded “Yeah…of course, these clothes are going to fit you…not me here real soon”

“That is so awesome…but once again…why are you doing this?” Jillian asked.

“Don’t worry about it…just enjoy it” Amber said.

Jillian had picked out a black skirt that came to Amber’s knees and a green top.

“Wait a sec…you’re not done yet” Amber said and she got up and walked to her top drawer, “Here, you’re going to need this” she said as she pulled out a bra and handed it over.

Jillian blushed hard. “Um…thanks” she said.

“I’ll help you” Amber said and she hooked the bra for her sister before she stepped back and reached up and took her own bra off under her large white top. She pulled it out and tossed it aside as Jillian stepped into the black skirt.

“How do I look?” Jillian asked and did a spin.

“You look like the older sister…you look like my big sister” Amber said. “As soon as I change any more age; you will be the older sister”

Jillian got a worried look on her face.

“Are you ready to be the big sister; I need someone to look up to and try to emulate” Amber said as she took off her socks and spanned out her toes. She got off the bed and stood up on her tip toes so she could be taller than Jillian one last time.

As she eased herself back down, Jillian nodded and smiled eagerly “I’m ready sis”

Amber took Jillian’s hands in her own and they both eased down to the ground in Amber’s room. They crossed their legs again and pressed them against the other’s legs and Amber giggled as their bare toes tapped each other. Amber shook her head and rolled her shoulders and tried to be serious but she burst out laughing again and Jillian joined her as they both laughed out loud.

“Okay” Amber said after both of their faces had turned red. “We’ll start off slow…transfer one year of my age to my sister Jillian so that she is thirteen and I am eleven”

Their eyes still held the others gaze as Jillian grew another inch and Amber lost two inches and it was Amber that felt it as Jillian’s bigger legs pressed against hers.
Jillian’s legs began to curve and mature as did the rest of her body. She put on weight more than grew taller in that year exchange and her chest tingled again as it began to grow. Jillian rolled her shoulders and wiggled slightly against the feeling.

Amber was now smaller and younger than her sister and she smiled as that fact ingrained itself into her mind. Her face thinned and lost any sign of maturity as she saw maturity creep into Jillian’s face. “So how does it feel to be older than me?” Amber asked her big sister.

“Wow…two years older than you now…it’s…I mean…I love it, it’s great” Jillian sputtered out. “You look so young to me…why does this feel so natural to me?”

“It’s all part of the transfer; you can’t be the big sister if you don’t think you’re the big sister” Amber replied.

“But” Jillian began “But it’s more than that. I know stuff…stuff I didn’t know before this…game, started” Jillian realized.

“Yeah…and…” Amber began.

“But if know these things than I’m guessing that you don’t know them anymore…am I right?” Jillian asked earnestly.

“I still know the game and how to play it” Amber responded with a smile.

Jillian smiled back and nodded before she said “More”

Amber nodded and said “Transfer two years of my age to my sister Jillian so that she is fifteen and I am nine”

With an overwhelming shudder, Amber re-entered her single digit years. She shrank down 4 inches and lost all trace of any curve or body definition. Her feet shrank smaller and she tried to flex her toes against her sister’s big feet but couldn’t get them to budge. Her legs were also being overwhelmed by the power and weight of Jillian’s growing legs. Amber’s hands were now much smaller than her sister’s hands and she held on as tight as she could as strength drained from her arms and upper body. Her skinny arms and chest swam in her previously tight white top with plenty of fabric bundled up at her wrists. She could feel a tingling in her face as it became the face of a nine year old. Her cheeks rounded and her chin, jaw, nose, ears and mouth all grew smaller on her face. She blinked several times as it felt like she had something in her eye as they too changed shape on her ever decreasing frame. Her hair thinned and lightened as a final step.

Jillian meanwhile was growing a lot between thirteen and fifteen. Puberty hit hard in those years and her body began to define itself. Her legs grew longer and fuller, her hips and rear flared outward pushing the black skirt out and up. Her arms grew longer and stronger and filled out the long sleeves of the green top. She began to fill out the previously empty bra and she swallowed hard at the tickle in her throat. Her face matured and her hair grew long and luxuriant turning a deep brown color. Her cheeks defined themselves and her nose grew longer as her face filled out more. Her lips began to grow puffy and full and her face took on a new maturity. Jillian sat on the floor now as a full teenaged girl, six years older than her little sister Amber across from her.

Amber smiled “It feels good doesn’t it?” she asked Jillian.

Jillian looked a bit shocked “Amber” she said “You look and sound like a little kid now…oh my God is that my voice?” she finished. She pulled her hands away from Amber easily and ran her right hand over her neck. “I sound like I’m an adult already” she added as her hands went to her hair and ran through it.

“Well, I am a kid now” Amber said with a shrug of her shoulders “And I know it feels great to be nine again”

“Why would you want to be nine again; fifteen feels awesome and I’m sure eighteen is going to feel even better” Jillian said.

“Soon enough” Amber said to her somewhat sarcastic sounding big sister “Are you ready?”

Jillian put her hands out, nodded, and said “Yes”

Amber took Jillian’s big hands into her own tiny ones and took a deep breath “transfer three years of my age to my sister Jillian so that she is eighteen and I am six”

With a final body racking shudder, Amber dropped down to just barely over four feet tall. Her skinny legs swam inside the women’s black leggings that she wore as she regressed back to age six. Her face was that of a first grader; her mind was that of a first grader and she was very happy. She smiled wide as she felt her body decreasing in size once more. She felt a tingle in her mouth and she brought her tongue up and slid it into a slot where she now had a missing tooth. She started to laugh at the thought of having baby teeth again and being visited by the Tooth Fairy. She looked over at her big sister and smiled.

Jillian grew just another inch taller which took her up to 5’7”, the same height her sister had been when she started. Her body filled out though as she became a young adult woman. Amber’s bra actually felt a bit tight on her as did her shirt. Her legs filled out and her face gained more maturity in it. She lifted her shoulders and pulled them back as she adjusted herself as her body changed for the final time. She gave her head a healthy shake and felt her hair whip back and forth over her upper back. “Are we done now?” she asked Amber.

Amber giggled again and said in a childish voice “Yea, we’re done”

Jillian pulled her hands back and put them on the floor to lift herself up. She stood up to her full height and brought her feet together “This is amazing” she said looking all the way down the front of her body.

She looked over at the small girl across from her. Amber was swimming in her old clothes as she struggled to get them off.

Jillian laughed as with a final stomp, Amber managed to get herself out of the big pants and top. She picked up the clothes that Jillian had discarded earlier and put them on her own small, slight frame. “There” Amber said. “All done…big sis”

Jillian smiled down at Amber “Thanks little sis”

“Do you like it?” Amber asked.

“Yes, of course I do…I always wanted to be the big sister…and now I am. But what about you?”
Amber smiled “This is what I wanted. I want to be your little sister...you’ll be a better big sister than I was”

“I don’t know about that…I…” Jillian began.

“There’s just one more thing” Amber said “You have to bend down though”

Jillian bent at the waist and leaned over.

“Farther” Amber said and Jillian bent down father and closer to Amber.

Amber stood up on her tip toes and put her forehead against Jillian’s. She put her hand on the back of Jillian’s head and pressed their heads together.

As they broke apart, Jillian stood back up and shook her head. She paused a moment and said “So what’s up squirt?” and she bent down and picked up the black pants and white top and tossed them into the dirty clothes hamper.

Amber shook her head and said “Do you want to play house with me?”

“I’d love to, but only for a few minutes and then I have to start my homework kiddo” Jillian replied.

“Yea…” Amber said and ran off to her room to grab more dolls to add to their game.

“Kids” Jillian though to herself as she followed her little sister Amber out of the room.
