“Alright you two…off to bed” 17 year old Isabella Hoffman yelled at her younger brother and sister.

“You’re kidding right? It’s not even 9 o’clock” her 12 year old brother Max replied.

“I’m not kidding at all; you two need to get out and go to bed…especially you” she said pointing to 7 year old Macy.

“You think you’re so hot just because Mom lets you babysit us when she goes out” Max said “But if you’re sending us to bed just because Charlie is coming over, I’m telling Mom”

“You wouldn’t dare” Isabella said.

“I would” Max said standing up to his big sister literally and figuratively.

“Fine” Isabella responded folding her arms “If you tell Mom, I’ll make sure everybody at your school finds out that you still wore a pull up when you were 9 because you couldn’t stop peeing the bed”

Max blushed bright red and seethed. “You wouldn’t”

“I would” Isabella said glaring down at him. She was a tall, skinny girl at 5’9” with long dark brown hair and big brown eyes that were strikingly beautiful usually but right now were just intimidating.

Max stomped off and up the stairs.

“What are you waiting for?” Isabella asked Macy who stood by the stairs.

“That was mean” was all she said before turning and going up as well.

“Don’t care…nothing you can do about it” Isabella said in reply. Charlie would be there any minute and she was intent on having those two out of the way.

Upstairs, Max fumed in the bathroom as he brushed his teeth. “Stupid” he said “I hate her”

Macy came in and started getting her stuff ready without a word.

“I wish I could get Isabella to do something so embarrassing that she couldn’t hold that over my head anymore. I wish I had the advantage over her you know Macy” Max said to his younger sister.

Macy just shrugged “What could you possibly do to her that wouldn’t get you in trouble and yet be so embarrassing to her in return”

“If I could figure out a way to get her to do something stupid in front of her boyfriend…something really embarrassing in front of him” Max said.

“But if anything happens, she’ll just blame you” Macy said.

“I know…that’s why it has to be epic” Max said.

Max was walking to his room when he heard the front door open and his older sister say in her fake high voice she only used around her boyfriend “Hi Charlie, I’m so glad you could come over tonight”

Max shuddered and walked on into his room. He picked up a picture that sat on his desk in a frame. It was a picture that showed him in the middle with Isabella on his right and Macy on his left. They stood in a row like steps in height “If only those two were reversed” he mumbled.

Max’s eyes widened after he said the words “That would be so much cooler if Macy were the older sister and Isabella the youngest…if only those two could somehow flip ages with each other”

“I wish Isabella and Macy would switch places” he said closing his eyes.

When he reopened them, they went as wide as they could “NO WAY!” he yelled out upon seeing the picture. The image was different. He was still in the middle but now a taller girl was on his left and a shorter girl on his right.

He knew Isabella was on his right and squinting at the picture, he thought he recognized that girl on his right from Isabella’s old pictures whereas the girl on the left looked like what he thought Macy would look like in 10 years.

Max dashed out of his room and into Macy’s.

Macy spun around at the rude entrance of her brother “What are you doing in here?” she said.

Max was somewhat disappointed that it was still the same old Macy before him but he went right up to her and showed her the picture “Look at this!”

Macy’s face looked confused and her eyebrows knitted down trying to understand what she was looking at “That looks like our picture from the beach last summer but who are those two with you”

“You’re never going to believe this Macy…I was thinking about how to deal with Isabella and I wished that you two switched places and you could be the big sister and she would be the little sister and  then…” he shoved the picture back at her.

“Are you trying to tell me that this picture shows me at 17 and Isabella at 7?” she said looking closely at the picture.

“Yeah” Max scanned the room. He ran to Macy’s dresser when he saw what he was looking for. He grabbed a picture there and laughed as heartily as he could “Look!”

Macy was scared all of a sudden. She walked over, her heart in her throat “Oh My Gosh” she said looking at her picture. In hers, she had been sitting on top of a big novelty dinosaur, feet dangling at least a foot above the ground, while Max stood to her left and Isabella was on her right.

Now, a long legged teenaged girl sat on top of the novelty dinosaur, her flip flop clad feet nearly scrapping the ground as Max still stood on her left and a small girl missing her front teeth stood to her right.

“What’s going on Max? I feel funny” Macy said.

Downstairs, Isabella was curled up on the couch close to Charlie. Her arms were wrapped around him and her head rested on his shoulder.  She was laughing at the story he was telling her when she suddenly snorted and her laugh cracked and pitched higher.

Isabella blushed hard and dropped her head embarrassed. As she looked down, she noticed her white tank top was hanging low so she quickly hiked it up.

Charlie smiled and looked over at the odd sound from his girlfriend but went right back to his story.

Isabella curled herself back up to him, scooting even closer this time and shifting her hips since her shorts felt loose across her body. Her stomach gurgled loudly and she blushed anew slapping her hand over it.

With her hand in place, her stomach began to pull inward. Her waist also came in and her hips and ass lost a bit of mass. Her thighs trimmed at first before they began to get slightly shorter.

Upstairs, Macy set her feet and put her hands out as the world seemed to swirl around her. She was dizzy and fighting for balance as she began to grow taller. Her legs began to stretch out longer and grow fuller and more mature as they went.

She felt her feet growing against the soft carpet below her feet. She felt her soles sliding longer and her heels widening as her toes lengthened out as well. “Max! What did you do?” Macy yelled at him, her voice already sounding different; deeper.

“All I did was make a wish! Wishes never come true!” Max said as his sister continued to grow and mature in front of him.

Her hips flared outward and her rear grew out round pushing her tiny shorts to their limit. Her stomach showed as her shirt lifted up and it revealed a tight and flat surface that kept growing longer.

Macy quickly matched and then passed Max in height. Her hair was growing longer and thicker as her arms grew longer and stronger as well.

She flexed her fingers and balled her hands up into fists as her hands grew larger and longer fingernails grew out. “Max” she said in a now deep and developed voice.

Max took a step backwards shaking his head at what he was seeing. Macy’s shirt lifted higher as her chest rose up. Breasts developed quickly into 34B’s pushing her tiny t-shirt out further from her body.

Macy put her hands up to her face as her features began to change there as well. Her chin and jaw jutted out stronger as her lips puffed out and her teeth changed into a full set out adult teeth.

Her nose grew longer and wider over more mature and defined cheeks. Her forehead widened, her ears grew, and her eyes widened and grew larger on her face becoming just as striking as her sister’s, as her face became that of a young woman and not a child.

Downstairs, Isabella began to fidget and squirm next to Charlie. Her shoulders felt tight and her legs were starting to ache.

“Are you okay?” Charlie asked her backing up a bit.

“Yeah, I’m just fine…Why?” she said in a higher pitched voice.

Isabella saw a look of confusion on Charlie’s face as he looked at her. “Because you don’t look okay…it looks like…I don’t know…something’s different about you tonight that I can’t put my finger on” Charlie said.

“You’re imagining things” Isabella said waving her hand. Her hand; Isabella stared at her hand because something was different. Something was off “Could my hand be…smaller?” she thought. Her fingers looked shorter; her nails looked shorter and more ragged.

“Um…excuse me” she said standing up but as she turned to leave the room, her shorts began to slide down off her hips and she had to stop and catch them.

“Oh my God” she muttered grabbing her shorts just before they fell off of her. Her shirt fluttered out way too loose on her and she spun around, her feet trying to gain traction on the wooden floors. Her balance was way off and her body felt different to her “Something’s wrong” she said.

“You’re damn right something’s wrong” Charlie said slightly panicked. “What the hell is happening to you Izzy?”

“What are you talking about?” she said, her voice sounding even a bit higher now. She stood up straight but quickly assessed that her sightline was off; Charlie was only 3 inches taller than her but now, it was more like a foot difference in their heights.

Isabella tore out of the room as fast as her shrinking legs could carry her. Her clothes barely hanging on as she clutched tightly to them. Charlie stood planted where he was, confused as he could be.

Isabella burst into the downstairs bathroom and headed to the mirror. She was not prepared to see the reflection that waited for her. She saw a girl who looked no older than 11 or 12 staring back and who was still changing and getting younger before her eyes.

She was much shorter in the mirror, her chin barely above the bottom rim of it but soon even that would duck down and disappear from view. Her features were soft and immature, those of a child and not a young woman.

Her eyes were still wide and doe-like but in a much more innocent way. Her nose was tiny, pert and upturned and her cheeks were chubby and round. Her chin and jaw were weak and her lips thin. She noticed that even her hair was changing: It was lighter and thinner, almost stringy.

Isabella looked down at her shrinking frame. Her breasts were gone; she could look down the front of her loose tank top and see that her bra was useless and hanging against her narrow and flat chest.

All signs of puberty had disappeared. Her hips and butt were flat and non-existent and her legs were short and pencil thin. Even her feet looked different; small and a bit pudgy.

“I’m a little kid!” she said in a very childish voice as she regained the age of 7 “How did I turn into a little kid again?” She began to hyperventilate and panic inside the small room.

Max ran down the stairs and pushed Charlie in the chest “You’ve got to get out of here” he yelled at the older and larger teenaged boy.

Charlie for his part; didn’t resist. He just turned and headed out the door without looking back.

If he had looked back, he would have seen a 17 year old Macy descending the steps. Her clothes snug and tight on her as she adjusted to her new size and the way it moved on her body. “Isabella?” she called out in her deep melodic voice.

“Where are you Isabella?”

A high pitched little girl’s scream coming from the bathroom answered her call.

Macy rushed to the door and opened it. Upon seeing what was behind the door, Macy began to scream too.

After their lungs had emptied the two stood before each other simply looking each other over up and down “Muh…Muh…Macy? Is that you?” Isabella finally managed to say.

Macy nodded “It’s me Isabella”

“What happened to us?” Isabella asked shakily “You…You’re big and I’m…I’m little”

“Well to be perfectly honest” Macy said folding her arms across her chest, pushing her boobs up “Max here wished that the two of us would swap places with each other”

“Max did this?!” Isabella stammered.

“I didn’t mean for it to happen Isabella; honest” Max said from behind Macy. He stepped around her and stood towering over his previously bigger sister “Wow…you got so small”

“Shut up!” Isabella said stomping her tiny foot. “Whatever you did, you have to change us back!” she yelled up at him.

“I can try I guess”

“What do you mean you guess?” Isabella said.

“Well, I don’t even know why it worked in the first place” Max said. “You were being all mean and bossy like always and I thought that if Macy was the older sister and you were the youngest, that things would be different and you wouldn’t have all the power over us.
So I made a wish…and it came true”

“Wish us back” Isabella said looking to Macy for support.

“Yeah…this isn’t right Max” Macy said.

“Ok” he said looking up to his now older and bigger sister Macy. He closed his eyes and sighed “I wish Macy and Isabella would switch places back to how it should be”

He opened his eyes and saw his two sisters looking at themselves and the other. “Nothing’s happening Max” Isabella said crankily.

“Um…I wish Isabella and Macy would flip ages” he tried.

Still nothing. The two mixed up sisters looked impatient with their brother. He turned and ran out of the room. He came back carrying the two pictures that he had seen changed earlier; both still showed the altered version of their family.

“Um…I wish Isabella was my big sister again and Macy was the youngest again”

“It isn’t working Max” Isabella said beginning to cry and get really concerned.

“You need to change us back Max” Macy said. “You can’t leave us like this”

There was a knock on the door and all three of the siblings looked at each other in panic. “You go answer it Max…you’re the only one here who’s still right” Macy said.

Max walked to the door slowly, he peered through the side window and saw it was Charlie on the other side.

“What’s up Charlie” he said cracking the door.

Charlie peered around him looking down the hall “Is Macy home?” he asked.

“Macy?” Max asked confused “What would you want with Macy?”

“Duh…she’s my girlfriend” Charlie said casually. “We’ve only been going out for like the last 7 months you know”

Max went pale white “No. You can’t see her tonight. My parents are gone and don’t want anybody over” he said robotically as he shut the door in Charlie’s face.

Max turned around and saw little Isabella and big Macy standing behind him; both looked super pissed off. “I don’t think this wish is going to work out too well for me” he said.

“Or for us you dumbass” Isabella said.
