Hannah Blake stood before the mirror in her bedroom. She puckered her lips, applying the light lipstick flawlessly on to her pouty full lips. “This has to be perfect tonight” she said to herself. “Senior Prom…” she added with a smile.

Hannah adjusted the spaghetti straps on her shoulders one more time and moved a few of the long full looping curls that her light brown hair was done in. She picked up the dangling crystal tear drop earrings and placed them into her lobes, careful not to touch her cheeks and smudge her make-up.

Hannah usually didn’t wear much make-up; she was a simple girl much happier in her soccer uniform than the formal, short dress that she wore tonight. She had on a silver and lilac A-line dress with a beaded and sequined halter top with spaghetti straps, the skirt was lilac chiffon that was several inches above her knees.

On her feet were a pair of strappy, open-toed four and a half inch silver heels that took her natural height of 5’7” up to just under six feet. Luckily, her boyfriend Travis was 6’2”. She glanced at the clock on the wall and said “Still another half hour until Travis even gets here for pictures…my feet are already killing me”

There was a light tap on her bedroom door and she knew who it had to be “Come on in Alexis”

The door opened up and Hannah’s 8 year old sister Alexis peeked inside. Once their eyes met, Alexis’ jaw dropped and she ran into the room and stood directly in front of her big sister. “Oh my Gosh Hannah…you look so beautiful! You look like a Princess!” Alexis exclaimed.

“Thanks” Hannah said as she blushed slightly. She did a quick twirl and sashayed her skirt back and forth for her sister.

“I can’t wait until I get to go to prom” Alexis said still admiring her sister’s dress. “I mean, you get to wear a fancy dress and shoes and get your hair and nails done and wear all kinds of make-up and you get to ride in a limo and…”

“Whoa…slow done there Lex…you will all in good time” Hannah said to her rambling sister.

“I know, but I want to do it now…I wish I was older” Alexis said.

“Don’t go wishing for life away; High School isn’t all cupcakes and Xbox games. There’s a lot of pressure and you’ll be there before you know it” Hannah cautioned. “I mean, there are times I wish I could go back to second grade; now tonight’s not one of those times but when I’m taking a Calculus test; well that’s a different story”

Alexis looked across the room and out the window. In her mind, she could see herself going to Prom; she saw herself grown up and even taller than Hannah but still wearing Hannah’s dress and shoes. She saw herself getting into the limo with Travis and getting a kiss from him. Then, in her mind, she saw herself waving good night to her family standing on the lawn and there in front of her Mom and Dad was an 8 year old Hannah waving to her.

Alexis giggled at her own imagination and the picture in her mind “If only that were true” she thought “What if I was the big sister and Hannah was the little one?”

Hannah saw the grin on her sister’s face and she snapped her fingers and said “Earth to Alexis; Come in Alexis”

Alexis smiled at Hannah and said “I hope you have fun tonight”

Hannah smiled back and straightened out her skirt and said “Thanks, I…” and she stopped. She glanced to the mirror and furrowed her brow in a bit of confusion. There in the mirror, she could see herself and her sister but as she looked at her sister’s face, something was different, something was wrong: Alexis had on lipstick.

“Alexis; what are you doing putting on my make-up?” Hannah asked her.

“What are you talking about? I didn’t put on your…uh…” Alexis said as she turned to the mirror and saw that she was in fact wearing lipstick. She put her finger up to it and felt the stickiness “Uh…what’s going on Hannah?” she said as she turned to her big sister.

When she turned, Hannah became even more confused. She looked at Alexis’ eyes and could see mascara and eye liner there. She was also wearing eye shadow, what appeared to be eyebrow pencil filling in her brows and foundation on her cheeks. Alexis was wearing full make-up on her childish face. In fact, she was wearing everything that Hannah had applied to her own face.

Alexis looked back and forth, her eyes darting between Hannah and the mirror. She had a sensation rising inside her that something big was about to happen. She was looking at Hannah and she had to gasp and say “Hannah! Your make-up’s gone!”

Hannah spun to face the mirror; sure enough, her face was make-up free. She looked at her plain face and said “What’s going on?” in a panicked tone as her hands came up to her cheeks.

Hannah took a step towards the mirror to examine her face and noticed that her foot slid in the shoe like it was too big on her foot. She looked down and it did appear that her heel was at least a size too big. Her toes no longer came up to the ends on the shoe and the straps were loose across the top. In shock Hannah looked down and saw the hem of her dress was down to her knees. It was too much too fast; her mind was reeling and she didn’t understand what was going on.

“Uh…Hannah” Alexis said “My clothes feel funny” Alexis was holding her arms out straight and watching her sleeves pull up on their own.

Hannah looked down at her sister, but not as far down as usual. As Hannah tried to process their change in stature, she got a sudden jolt as she suddenly dropped down. “My shoes!” she yelled as her heels hit the ground. Her shoes had disappeared off her feet and Hannah now found herself standing barefoot on the carpet in her bedroom. “Where did my shoes go?!”

“Um…Hannah” Alexis said. Hannah looked over and saw that she was looking directly into Alexis’ eyes. Alexis looked down to the ground and pointed. Hannah’s eyes trained downward and saw that her strappy silver heels were now on Alexis’ feet and they fit pretty well.

“What the hell is going on here” Hannah said. “Oh No…NO!” she yelled as Alexis grew taller than her.

“Uh…I don’t know what’s going on either Hannah” Alexis said as she looked down at her sister “I mean it doesn’t make any…oop” she stopped and flung her arms across her chest as Hannah’s Prom dress now appeared on her body.

“AH!” Hannah yelled in shock at seeing her dress appear on her growing sister. More than that, the body it revealed seemed more than capable of keeping the dress on and up. “Alexis! You have boobs!” Hannah yelled.

Alexis looked down and sure enough, saw cleavage holding up the halter top of the dress. Her breasts were still growing out and filling up the built in bra cups in the beaded and sequined top, pushing it out further and feeling the straps pull tighter against her shoulders.

“AH!” Hannah screamed again as she looked down at her own body and saw that she was now wearing the yellow top and green shorts that Alexis had on when she entered the room. She was initially surprised at their swap in clothing, but even more disturbing was the fact that the clothes seemed to fit her. Hannah’s chest was going flat along with her hips and rear. She was shrinking and losing all signs of curves on her body.

Alexis continued to grow taller. She turned to the mirror and thought “Wow! That make-up really makes my face look mature” But it was more than just the make-up. Her face was maturing into that of an 18 year old woman. Her lips filled in, her teeth grew larger, and her chin and jaw strengthened and became defined. Her nose grew longer and wider and her eyes offset and grew larger as her cheeks rose up in sharp contrast to Hannah’s face which was quickly regressing back into childhood.

Hannah looked at her plain face, still framed by her fancy hair do as it became younger looking. Her eyes narrowed and her nose shrank down. Her lips thinned and her teeth shifted into a child’s small teeth. Her chin pulled in and her defined and sharp cheeks disappeared into chubby round cheeks spotted with freckles.
 
As Hannah looked on, her earrings disappeared and even the holes in her lobes closed up. Her hair flattened and pulled inward into the shoulder length dirty blonde that she had been the first time she eight.

It was then that Alexis’ hair began to grow long and wavy. Long loose curls came in and her hair pined back as if it had been professionally done. The crystal earrings popped into her ear lobes and accentuated her long almost black hair.

Her feet reached the ends of the strappy silver heels and her toenails were topped off by pedicured nails with lilac polish. That same lilac color filled in her fingernails on her now much longer and slender fingers. She stood at a full 5’9” without heels, and with them she towered over Hannah, who now barely topped out at 4’7” in her bare feet, accentuated by chipped blue nail polish and crude painting job.

“Hannah?” Alexis said in a much deeper and mature voice “Is that you?”

Hannah nodded on the verge of tears.

“What happened to us?” Alexis asked. She looked around and up and down. Hannah looked like a little kid to her. She was small, was wearing her old clothes and had a childish face, streaked with fear and confusion.

“I don’t know Alexis…you’re big now, and…and I’m not” she said as she looked over and up at her now much bigger sister. Alexis loomed over her, looking like the older sister ready to go to her senior Prom.

Alexis stared into the mirror at the image reflected back. It was her, but yet, not her. She was tall...huge really compared to a few minutes ago. She was wearing Hannah’s silver and lilac Prom dress and her silver heels and they both fit her perfectly. She had developed curves and breasts and long legs. She was wearing make-up and could tell that her nails were both pedicured and manicured. Her hair and make-up were flawless on her mature face.

“Oh My Gosh Hannah; we switched places! I’m the big sister now and you’re the little sister!” Alexis exclaimed as she jumped up slightly. “This is so awesome! I’m going to Prom…not you!”

“What are you talking about Alexis?” Hannah replied in her high pitched childish voice. “This is not awesome! I’m supposed to be the big sister; not you! I’m supposed to be going to Prom! What’s going on?! I’m not your little sister!”

Hannah looked down and smirked “You sure look like the little sister” she said as she hefted her breasts and smoothed out the front of her skirt.

“But this is impossible!” Hannah protested.

It was then that they heard their Mother calling from the bottom of the stairs “Hannah?”

“What I am going to do?” Hannah said in sudden panic. “If I answer her sounding like this…she’ll freak out”

“Hannah” their Mom called again “You’d better not be bugging your sister while she’s getting ready”

Alexis and Hannah’s eyes both widened at what they had heard. “What?” they both mouthed silently to the other.

“Travis will be here any second…you’d better be just about ready Alexis” their Mom called up the steps.

“She thinks I’m the oldest” Alexis said.

“But…but…this can’t be happening” Hannah cried.

Alexis folded her arms across her chest and tilted her head down towards her little sister “Looks like I’m going to Prom tonight with Travis, sis” She turned and grabbed the small clutch purse off the nightstand and she effortlessly walked out of the room.

Hannah trailed a step behind her sister’s long strides down the hallway.

“Out of the picture Hannah” their dad said as they reached the top of the stairs “We want to get shots of Alexis all dressed up and ready to go”

Dejected and shocked, Hannah backed up and cleared the picture taking frenzy. “I can’t believe this…this isn’t happening” Hannah said to herself.

Alexis heard it and glanced over her shoulder at Hannah and smiled just for her before she turned back around for more poses coming down the stairs.

A rumble of a car engine outside, announced that Travis and the Limo had arrived. Alexis’ heart raced as Travis walked up to the house and her Dad let him in.

“Wow Alexis” he said. “You look so beautiful tonight”

Alexis smiled and said “Thank You…it means so much to me to hear you say that to me”

Hannah stood in shock at the top of the stairs watching the scene play out. Travis never did notice her.

The couple went out onto the front lawn to pose for more pictures and Hannah quietly slinked down the stairs and out the front door. She watched them hold hands and there was a picture taken of Travis planting a kiss on Alexis’ cheek that made Hannah’s cheeks burn deep red.

It was time for Alexis and Travis to get going so they could make their dinner reservations. As her Mom and Dad waved and told them to have a good time, Alexis made a point to wave and say good bye to Hannah “Good Night Hannah; don’t stay up past your bedtime waiting for me to come home!”

Hannah saw the quick thigh rub and ass grab that Travis managed as they climbed into the back seat of the limo and as they drove off; she crossed her arms and stuck her tongue out instead of waving.
