“Shelby! I want to ride that one!” Nora Beckett yelled out excitedly to her older sister.

“I don’t know Nora, that ride is going to be too big for you” Shelby replied wincing to try and sell how big and scary the Thunder Drop ride would be.

“No way…I’m big enough for that. It won’t scare me” Nora insisted.

“It’s not that Nora” Shelby said as they walked up to the ride. Shelby Beckett was 17 with long brown hair and big green eyes.

7 year old Nora bounced around behind her big sister as they made their way to a carton dog with his cardboard hand out and a speech balloon stating “You must be this tall to ride this ride”

Shelby pointed to the sign; Nora was clearly about 6 inches too short. “But I’m 4 feet tall!” Nora announced.

“I know, but they want you to be this tall for this one…you don’t measure up yet shrimp” Shelby said giggling to play it off.

“That’s not fair!” Nora said stomping her small foot on the beaten down grass.

The annual carnival was in town; every year, in the first week of August their town had a parade and a carnival on the fields around the High School. The aroma of fried foods filled the warm night air as blinking lights from the rides and the calls of the carnival games surrounded them.

“I don’t make the rules kiddo” Shelby added with a shrug of her shoulders.

Nora shook her head and wrinkled up her tiny face. Her short brown bobbed hair flew back and forth as she folded her arms over her chest and the white tank top she wore. “Isn’t there anything you can do to get me on that ride? I really want to go on it this year” Nora whined.

Shelby raised one of her sculpted and thick eyebrows. A slight mischievous smile crossed her lips “Maybe there is something…” she said meeting her sister’s eyes. “Come with me”

They crossed the field to the side that was much quieter. A few Semis were parked and they ducked between them.

“You can never tell Mom and Dad so you have to swear that this is our secret and if you ever do tell them, you’ll be in a lot of trouble with me okay” Shelby said looking around to make sure they were alone.

“Of course I swear” Nora replied.

“Okay” Shelby paused “The truth is…I’m kind of a witch”

“Whatever Shelby…you’re lying!” Nora replied.

“No it’s true…I know some spells and I’ve cast a few…how do you think I got Ryan’s attention” she said mentioning her boyfriend.

“You’re just lying to try and cheer me up” Nora said.

“No, I can prove it and in so, I can also get you on Thunder Drop” Shelby said looking smug.

“Whatever, I’ll believe it when I see it” Nora said with a dismissive flip of her hand.

“Fine, If you don’t want to be older and big enough to go on your ride, then just go” Shelby said.

Nora was quiet for a moment and thought “Did she say she could make me older and bigger?” She took a step closer to her big sister. Shelby was tall, 5’9” while she was just 4’2”. “Alright…you’d better start talking and making some sense here” Nora said.

“There’s a spell…I read it and I know it can work; what it does is…it would take a few years from me and give them to you”

“No way!” Nora said.

“Yeah…I can make it so for tonight only, I give you 4 years…you would be 11 and I would be 13. We would both be tall enough to ride everything!” Shelby said.

“But what about your friends? The whole town is here. Wouldn’t you be embarrassed if one of your friends recognized you as a 13 year old?”

“That’s what’s so great about magic…reality changes for everybody else except the two of us! We’re the only ones who know anything is up. Let’s say that we run into Mr. and Mrs. Aldridge” she mentioned their next door neighbors who they had passed earlier “They would still know us as their neighbors and as sisters, but to them, there would always have only been a two year gap between us!”

“So if we run into middle school kids; they’d know us?” Nora asked somewhat confused.

“Yep” Shelby said happily.

“What about our clothes?” Nora asked.

“Reality changes…our clothes change too to match us…duh” Shelby explained.

“Then what are you waiting for?” Nora said throwing her arms out “Make me an 11 year old!”

Shelby smiled “Trust me…this is going to be fun” She flipped her long hair off her shoulders and stood up straight. She wished she had her actual spell book with her but she had memorized everything in there so she was confident in her words.

“Power to shrink power to grow, swapping ages is the way we go,

To give my years free and clear, to accept them, my sister dear,

I give years of my age to my sister, so chances have not clearly missed her,

Let this power pass between us, my sister and me, change our age to all who see”

Shelby nodded and smiled.

“I don’t feel anything different” Nora said putting her hands on her hips.

“Give it a second…watch” Shelby said.

Nora felt a little warmer. She realized she was holding her breath. She looked down at herself in anticipation. Swallowing she looked back up at her sister. She gasped.

“Shelby!” Nora said surprised.

“Noticing anything yet?” she asked raising her eyebrow again.

“Yeah!” You don’t look as tall to me!” Nora said.

“I think it’s because you’re growing” Shelby replied.

Nora stuck her leg out straight in front of her “She’s right! It does look longer I think” she thought wiggling her dangling foot in a circle.

Nora gasped again and put her hands to her mouth to stifle her scream. She foot, clad in a purple flip flop began to grow. In mid-air, it grew wider and longer. Her toenails became larger and easier to be seen and the polish on them changed from a garish bright pink, to orange.

Her shoe grew larger and changed from purple to simple black. She put her foot back down and saw that her left foot had changed to match the right and that her feet looked farther away from her eye.

Nora looked at her sister’s feet and cocked her head in confusion. The already tall High School senior had been wearing a fancy pair of lace up beige wedge sandals, not entirely practical, but something very much in line with her fashion standards.

Now, she had on a simple pair of grey Toms.

Shelby looked down at her more practical footwear choice. She lifted her big toes up against the fabric, pushing up a peek at the ends “Much more in line with what a 13 year old would wear” she announced wiggling her toes up and down making the fabric dance. “My legs are skinnier too!” she announced.

Shelby’s legs were thinner already and a bit shorter. Going back to 13 had taken her back to about 5’5”; still tall for her age, but not as imposing.

Nora was going through a growth spurt. “Whoa!” she said as her legs sprouted up longer, hiking her shorts up higher. Her plain yellow shorts now also changed to black and came back down to cover most of her thighs. Slight hips flared outward as well.

Her white tank top remained the same but went up a few sizes covering her chest as she began to grow. A new piece of clothing now popped onto her chest. She felt thin straps going over her shoulders and a single piece holding down her chest beneath her tank top.

Nora’s hands flew up and pressed down “Training bra?” she asked confused.

“Probably…small bumps in a thin shirt need covering” Shelby said.

Nora’s arms lengthened and remained thin as her fingers grew out longer. Her nails now topped with the same orange color as her toes.

Nora smiled as she saw her sister diminish before her. Shelby’s shoulders pulled in, her arms pulled up and her hands and fingers got smaller.

Shelby’s clothes were now changing as well. Her denim short shorts were looser than she had intended and they grew longer, changing into a pair of Capri pants in a much smaller size as her hips and ass slimmed down along with her legs. Her green top came down several sizes as her stomach, chest and back thinned and trimmed but the biggest change was to a garment that nobody could see.

Shelby’s bra pulled in, changing as her breasts shrank. Shelby went from a 36C to a 34A “I did not think about that change when I offered to do this” she said clutching her now very small breasts. No longer round and full, they were small and cone shaped, much more a girls chest than a young woman’s.

“You look really different” Nora told her still slightly older sister.

Shelby’s hair came up a bit shorter and it thinned, stray hairs spun out and stuck out as her chin and jaw weakened, her lips thinned and her teeth shrank “MMMPFH!” she exclaimed as she locked her lips tight.

“What is it?” Nora asked.

“Shit” Shelby said with a slight lisp “I’ve got braces again dammit!” She bared her teeth revealing the metal now clamped down across them.

Her nose shrank up, her cheeks rounded and her eyes narrowed. Her thick and bold eyebrows lengthened, thinned and got a bit unruly as she no longer possessed the make-up acumen she had at 17 as a 13 year old.

Nora’s hair grew out longer. Her bob style was no more as she now had brown hair down past her shoulders. Her brown eyes widened and her chin and jaw came out more forcefully. Her cheeks slimmed, her nose grew and her lips filled in.

“Wow” Shelby said looking over her sister “You grew up quite a bit…you have to be around 5 feet tall now”

“Plenty tall enough to ride Thunder Drop” Nora exclaimed putting her hands and arms out, flipping them over in examination.

“Let’s go!” Shelby exclaimed running out from between the semis.

Nora was able to easily keep up with her longer legs now. They scampered through the crowd and got into the end of the line.

They chatted easily as the waited their turn.

The guy working the ride never gave Nora a second glance as she easily passed by the cardboard dog with his paw out. He locked both of them into their safety harnesses along with the other 6 people riding that go around.

“This is the best ride ever!” Nora shouted as they jerked up and down seemingly at random.

“Come on Shelby…I want to ride everything!” Nora shouted. She grabbed her older sister by the wrist and pulled her along to the next ride. The line wasn’t very long and they’d be on the next trip.

“This is so cool, even if it’s just for tonight. We have to ride everything we possibly can!” Nora said.

“Whatever girl” Shelby responded. She hiked up her shirt slightly as she waited “Being smaller already…I can barely keep this top up now” she mumbled to herself.

They rode the Music Express and the Dust Devil in rapid succession before jumping in line for the Whirlybird.

Catching her breath, Nora fanned herself with her hand. As she did, her training bra separated and slid, turning into a 34A bra which now held up her slightly larger breasts. Her shirt went up a size along with her shorts and shoes as her body grew 2 inches taller and she became 12 years old.

Shelby turned her back on her sister once they were in line and scanned the crowd for a moment. She put her hands on her hips as her hips slid in ever so slightly and brought her rear in with them. Her thighs trimmed and she shrank down about 2 inches as she ran her hand through her hair.

Shelby regressed another year to 12 as she hit 5’3”. Her shoes tightened up a half size but didn’t change style even as a pink rose embroidered itself along the leg of her Capri pants.

“There’s my favorite twin sisters” she heard Mr. Aldridge, their next door neighbor say to them as he passed by.

“What’s he talking about?” Shelby thought but shrugged it off as it was their turn through the gate and onto their ride.

The Whirlybird spun them around and they repeatedly bumped up against the other as their cart spun back and forth. On one particularly long spin to the right, Nora leaned into Shelby laughing in her ear as she became to older of the two of them.

They got off and had to take their time leaving out of the gate. Nora was now 13 and Shelby was now 11, the fact that both of them were hunched over was the only reason they didn’t discover their change any sooner.

The spell that Shelby had unleashed had been incomplete but she hadn’t known that when she cast it. By not putting a definitive limit on the years they would swap, they would continue to swap until their difference in age was completely reversed.

As Nora led the way to the next ride, The Viking Swing, she began to change. Her height continued to increase. She now stood 5’4”. Her bra bounced up a cup size to a 34B as her tank top stretched tighter as she wanted to show off a bit now at this age. Her black shorts rode higher as her hips slid out and her ass began to round and lift up. Her legs filled in and her flip flops continued stretching out to keep up with her growing feet.

Nora’s nail polish changed on both her fingers and toes from orange to red as her hair grew slightly fuller and longer and her features matured.

Shelby had a hard time keeping up with her sister as they cut through the crowd around most of the food vendors on their way to the Viking Swing. Her legs were shrinking again and getting skinnier as they did. Shelby dropped down to 5’2” and her feet shrank down another size as she ran. Her grey Toms now morphed into a pair a light cotton white sneakers, dirty and scuffed around the toes with a slight tear at her right big toe in the top fabric.

Shelby tucked her shrinking arms in close to her side as she ran, her bra changing shape into a solid one piece training bra, the straps thinning as it pulled tight over her now nearly totally non-existent breasts.

“Slow poke!” Nora teased as Shelby caught up out of breath and got in line with her.

Shelby was bent over, her hands on her knees catching her breath when she noticed her shoes “What the…?” she said cocking her head. Her long brown hair fell down past her face, dangling as she looked.

“What the…?” she repeated as she caught the changes to the outside of her jeans as well “What’s going on with my clothes?”

Shelby lifted up her right big toe and saw a small nail, painted pink, pop through the hole in the top. “That looks awfully small” she thought.

Shelby stood up as Mrs. Aldridge passed by and tapped Nora on the shoulder “You watching out for your little sister?” she asked without stopping.

“Um…yeah” Nora called out confused to her neighbor.

Shelby was examining her clothes “Am I skinnier?” she asked touching her leg.

“Next riders up!” the greasy looking guy called out.

Nora rushed ahead with the crowd and Shelby bounced behind her “Wait up Nora!” she called out.

“Wait a second Miss” the Carny said. Nora stopped but he waved her on “Not you” he said to her “You” he pointed at Shelby.

Shelby stopped as he swung around his modified yardstick and put it right at her head “You’re okay…get on”

Shelby shook her head but rushed on to make sure she could sit next to her sister.

“What was that all about?” Nora asked as they strapped in.

“I don’t know…guess he thought I looked short” Shelby said, her cheeks burning red with embarrassment.

“Bet ya that hasn’t happened to you in a long time” Nora teased.

“Um…yeah…” Shelby laughed nervously as the Swing began to rock.

Shelby gripped the bar as tight as she could. With each swing, she felt her smaller body lifted up off the seat and pressed against the bar. Nora seemed like she was hanging in there just fine as she caught glances of her out of the corner of her eye. She was smiling and yelling in rhythm to their swings while Shelby was getting worried about getting tossed off.

The Viking Swing was in full swing; it was getting close to the spot where it would pass around and make its full swing around. As they rushed forward, Shelby’s braces came off her again. Her teeth were now a mix of adult and baby teeth, too young for braces.

Her brown hair shrank up higher as it flew out behind her. Her eyes narrowed even more and her cheeks rounded up to apple fullness as her lips thinned and her nose shrank along with her chin and jaw.

They cranked up and slowed down as they neared the top. Her green top loosened and changed into a green t-shirt with a pink sparkly butterfly on it. Her training bra vanished.

Her Capri pants changed into a pair of yellow cotton shorts as her legs shrank down even shorter and thinner than before just as her feet shrank inside her beat up and now too large white sneakers.

“Here is comes!” Nora screamed as they passed the top and shot down fast going the other way. Her hair grew long and thick behind her in the wind. Her nose broadened, her eyes widened, her eyebrows thickened as her cheeks slimmed and her chin and jaw strengthened.

Nora laughed as her lips plumped and her white teeth grew larger and straighter. Her white tank top continued to grow in size but remained tight and tapered to her narrow waist. Her 34B bra went up to a 36C as her breasts plumped and filled in. Her hips slid out and her ass plumped giving her extra cushion against the hard padded bench she was sitting on.

Her black shorts tightened against her filling and rounding and maturing thighs. Her panties changed to a bikini cut as her legs grew longer along with her feet. Her plain black flip flops changed; a more elaborate pattern of straps came over the tops of her feet and her ankles as they changed into a pair of black sandals.

Nora looked over and realized something had changed; her sister looked different; she looked really little and young.

Shelby was terrified as the ride finally began to slow down. The now 9 year old panted holding back tears of fright as they came to a stop.

The bar lifted up and she sat frozen. Nora unbuckled her and tapped her shoulder “Come on…we’ve got to get off of this”

Shelby got up in a daydream and stumbled forward. The Carny gave her a look as she clearly was an inch shorter than the sign showing minimum height, but he didn’t say anything for fear of being fired.

“Something’s wrong Shelby” Nora said escorting her off to the side of the ride. Nora’s heart began beating harder seeing how small Shelby was compared to her.

They ducked behind a food tent and Nora looked down “Oh my God” she said taking in the very childlike Shelby “Shelby? Are you okay? What’s going on?” Nora asked.

Shelby caught her breath. She looked around and saw that there was no crowd around them before she turned and focused on her little sister.

Shelby turned and froze again. Her jaw dropped and she was unable to make a sound “Holy…” her mind fought for the appropriate word “Nora” she finally managed in a very high pitched sounding voice “Is that you?”

Nora nodded and bit her bottom lip. She was 15 now and stood 5’6” to Shelby’s 4’9” “Why is this happening? Why are we still changing? You were only supposed to grow to 11 and I was only supposed to stop at 13” Shelby stopped and looked up at her much larger sister “You’re obviously older than 11”

“Yeah…and there’s no way you’re 13…you look more like you’re 9” Nora said.

“I know that you…” she couldn’t find words in her mind to express her anger which just led to more frustration for her “ERG!” she yelled out in frustration as she jumped up, still staying shorter than Nora.

“What was that spell?” she said mostly to herself.

“What? I thought you said you memorized all the spells?” Nora said.

“I did memorize them” Shelby said before she looked down at the ground “I just can’t remember them all now”

“But…that would mean” Nora began.

“I know that you…ugh…why can’t I swear effectively anymore!” she yelled at the sky.

“Okay…just let me think…” Shelby said. “Growing older, growing younger, we swap ages freely”

“That doesn’t sound like what you said earlier!” Nora said.

“What?” Shelby shot back “Yeah…I know, I was just testing you.”

She cleared her throat “Power to shrink, power to grow, this is the way we choose to go,

Reverse our ages to the way we were, the right one younger, me older than her,

We return to our ages as we started the day, no longer changing obey what I say,

Return us to our rightful state, our ages correct for our fate”

Shelby looked around “That should be the spell to reverse this”

Nora swallowed nervously. She felt warmth pass over her again but instead of her anticipated shrinking, she began to grow again. It was Shelby who was shrinking.

“NO!” Shelby yelled out as she got even younger “That wasn’t it!” she stomped her foot as it shrank down even smaller. Her legs shortened up and actually looked stockier again as some baby fat came back onto them as she became the 7 year old of the two of them. Her body was straight up and down, a girl’s body with no curve. Her dirty sneakers covered her tiny feet as cotton shorts hung down almost to her chubby knees. Her green shirt now had a sparkly representation of Tinkerbell on it.

Her thin brown hair pulled up into a short bob haircut, reminiscent of the one Nora used to wear, but Shelby’s was slightly longer in front.

Her features shrank down even more childlike conveying her new age effectively and thoroughly.

Nora grew one inch taller taking her up to 5’7” at 17 years old but her shoes began to change which lifted her up even higher. Her flat sandals changed to three inch wedge heeled ones and she wiggled her toes in the stylish shoes showing off her dark red polish.

Her black cotton shorts changed to black denim with silver accents. They rose up high and tight over her ripening thighs as her hips flared and her ass popped out rounder.

Nora waist and stomach came in and her bra had to change yet again to a 36D under her tight and skimpier tank top.

Her hair swept forward over her forehead even as it grew longer down her back. Her features sharpened and her lips filled out even more. Make-up appeared for the first time on her face accentuating her lips with liner and gloss and her big brown eyes with lash and liner as her eyebrows textured and manicured down sleek and fierce.

“Whoa” Shelby said looking up to her very put together and fashion forward big sister.

“Wow” Nora replied. She looked down checking out her body “I’m huge!” she said as she pat down her chest and stomach and stuck her right leg out kicking her ankle back and forth, feeling the weight of her high heeled shoe.

“I’m guessing that you don’t know a counter spell for this do you?” Nora asked her little sister bending at the waist to get to her eye level.

“No” Shelby admitted quietly shaking her head.

“That’s okay” Nora replied standing back up to her full height and smiling down at Shelby “You just look so…oh my god…so young!”

“Shut up…this was you a little bit ago and don’t you forget it!” Shelby said.

“Oh I won’t forget it and neither will you” Nora responded.

“Yeah, cause I’m sure you won’t let me forget it” Shelby shot back.

“Not as you grow up again as my little sister I won’t” Nora admitted. She began to walk out from behind the food tent.

“Where are you going? Wait up for me!” Shelby called out as she followed her sister. The crowd was much more intimidating to her now, so big and so many people so much bigger and older than her surrounded her. “Nora wait! I don’t want to get lost!” she called out.

“I’m right here” Nora said appearing by Shelby’s side to her great relief. “Hey, I got a text from Ryan. He’s here and I told him we’d meet by the Caterpillar Crawl. I figured you could ride that while we talked okay”

“What?! You can’t…!” Shelby began but was silenced by Nora pulling her phone out of her back pocket and showing a picture of Ryan holding her as her wallpaper.

“Oh yes I can” she said in a sing song voice. “He’s mine now…thanks reality change!”

Shelby folded her arms over her flat chest and made the grouchiest face a 7 year old could manage.

“We’ll but you some cotton candy!” Nora told Shelby, which made her stop frowning.

“And I get a Coke!” Shelby added.

“Of course…and a corn dog; it’s the carnival after all” Nora said as they headed to the kiddie rides.
