“Happy Birthday Addison” Melanie Franklin told her 10 year old niece as she came in the house.

“Thanks Aunt Melanie…I’ll take that thank you very much” Addison said taking the present from her arms.

“Double digits…wow…it seems like I was just holding you when you were a little baby” Melanie said taking off her shoes.

“Come on…don’t embarrass me” Addison said blushing slightly.

“Hey Mel…glad you could make it” Addison’s Dad and Melanie’s older brother Mark said coming in and giving Melanie a hug.

“Wouldn’t miss it for the world big brother” Addison said. “You remember my boyfriend Alan right?”

Mark and Alan shook hands “Of course, good to see you again. Come on in; pizza will be here in a few minutes…can I get you guys something to drink?”

“Diet Coke if you’ve got it” Melanie said walking into the room and smiling at the other guests and family members.

“Aunt Melanie; you’ve got to come see my room: Dad just repainted it and I got all kinds of cool new decorations up”

“Okay…lead on” Melanie said. “You’re okay down here by yourself” she asked Alan.

“Yeah…I’m fine: Go have fun and check it out” he replied.

Melanie grabbed the Diet Coke from her brother as she headed to the stairs. They exchanged a smile as Addison rushed upstairs.

“Slow down Addy…” Melanie called out as Addison took the stairs two at a time, scrambling up them.

“Hey, so, you’re 20 years older than me right” Addison said watching her Aunt climb the stairs. She took a drink of the Sprite she had with her.

“Yes…I’m 30” Melanie responded.

“So in another 10 years we’ll be a story problem: In 10 years, Melanie will be twice as old as Addison…how old are they right now?” Addison laughed.

“You’re right…you’re pretty smart kiddo” Melanie said when she reached the top.

Addison smiled and ground her heel into the carpet. Addy came up to her Aunt’s chin; she was a tall skinny kid for her age but her Aunt was 5’8”. Melanie had on black leggings and a long red and black flannel shirt that she tugged on as they headed down the hall to Addy’s room.

Addy went ahead and flipped on the light revealing walls that were light green instead of pink.

“This is so cool Addy” Melanie said stepping in. A white comforter lay on the bed and a new desk sat against the wall. In the corner was an old fashioned standing floor mirror. “I love those types of mirrors…they are so neat” Melanie said heading for it.

“Oh I know…I love it” Addison agreed and stood next to her Aunt before the large oval mirror.

Melanie put her arm around her niece “This is one cool room; I wish I had a room like this when I was your age”

“Thanks” Addison said.

Melanie walked to the bed taking in the room when she heard behind her “Alan is really cute”

“Addison! You’re not supposed to notice things like that yet are you” Melanie was blushing. She brushed her blonde hair back off face, tucking it behind her ears.

“Well, he is” Addison said laughing. “I’d date him if I was your age”

Melanie laughed too “Well I’m glad I don’t have you as my competition”

“I wonder what it would be like if we swapped ages: Like if I was 30 and you were 10” Addison said.

“So what…you want to see me as a little kid while you get to be the adult” Melanie said as she lifted the can in her hand to take a drink.

“Yeah that would be so awesome!”  Addison said.

“Ugh” Melanie said swallowing and spitting and coughing. “What the…why am I drinking a Sprite?”

Melanie looked down and saw the green can in her hand. Her eyes traced over to her niece and she saw that she was taking a drink from a can of Diet Coke. “But…” she said confused.

Addison didn’t look concerned about the change in her drink as she continued smiling.

Melanie walked back across the room to the mirror but what she saw made her stop short. “What the…oh my god look at…” She stared into the mirror before she looked down at herself. She slapped at her chest and ran her hand down her side to her thigh.

“Oh My God” she repeated looking at the difference between the image in the mirror and her body below her.

In the mirror, Melanie saw a little girl: More to the point, she saw herself as a 10 year old.

“Addison: Come over here! You have to take a look at this!” Melanie called out and waved her niece over.

“What is it Aunt Melanie” she said walking to her. “What is so…oh my gosh look at me!”

“AH!” Melanie let out a quick scream and put her hands up to her cheeks when she saw the sight next to her. “What is this…some kind of fun house mirror?”

There in the mirror stood an adult looking woman where Addison’s reflection should be. “So if that’s a 10 year old me in there…that must be a 30 year old you Addy” Melanie said slowly. The shock on both the real and reflected Addison was obvious.

“This…this can’t be…what’s going on Aunt Melanie” she whispered looking at the tall brunette woman before her. Addison had on jeans and a plain blue top. In the reflection, the woman was also wearing jeans and a blue top but it showed a woman with an adult’s body and curves in contrast to what she saw below her.

“It’s like it’s showing us what my wish would look like” Addison said excited. “It’s what we’d be if you were 10 and I was 30. I wonder if that would make me your Aunt then”

“Don’t joke about that…that would make my brother my Dad and you would be his sister then…yuck” Melanie added.

Melanie’s reflection was also dressed the same with leggings and a long flannel but they hung loosely over the small girl’s frame. Their heights were reversed in the mirror as well with the small Melanie only coming up to the chin of Addison.

“I don’t know honey…this is really, really freaky. Has this ever done this before?” she said pointing to the mirror.

“No…never…why would it?” Addison replied. She took a step closer to the mirror and examined her face. It looked like her but of course, much older and more mature. Her nose was longer, her mouth bigger, her cheeks sleeker, her eyes wider, her chin more prominent; she was very pretty with her long brown hair tossed casually over her right shoulder.

She even put her hands up to her non-existent boobs just to watch them go up and down in the mirror.

“Stop that!” Melanie said and slapped at Addison’s hands. In the mirror world, the small girl knocked away the woman’s hands from her ample chest. Yet Melanie turned to the side and pulled her shirt tight looking in the mirror at the flat chest reflected back and the complete and total lack of hips or a butt.

“This is so weird” Addison said “You look so cute as a kid”

“Shut up” Melanie said a bit embarrassed. She leaned forward and the reflection leaned closer. She took in her juvenile and youthful face; a face that she had kind of forgotten. The thinner lips, the small pert nose, the narrow and squinty eyes, the freckles and the stringier long blonde hair that lay limp over both shoulders.

“Melanie! Addison! Come on downstairs…food’s here!” Mark yelled up the stairs.

Both of them spun around to the door and put their backs to the mirror. As they did a wave of dizziness washed over both of them. “We’ll be right down” a high pitched kid’s voice rang out as Melanie’s eyes widened and her hand went to her throat at the shock of that kid’s voice coming from her.

Addison couldn’t even speak after she heard her Aunt’s voice sounding so different but her eyes widened too. First at the sound she had heard, then at the sight she was seeing. There before her eyes, her Aunt Melanie was shrinking.

Addison took in a sharp gasp of air as Melanie began to drop down smaller and smaller in size.

Melanie felt strange, like the room was expanding around her. She felt a shift in her body and she spun toward her niece. “Oh No!” she said in that high pitched voice as she saw that Addison was changing in front of her. Addison was growing and changing into a woman as she shrank and changed into a kid.

“Oh No” Addison echoed in a deep mature woman’s voice that rolled out of her growing body and expanding chest.

Addison’s legs grew longer and began to fill out and gain an adult’s curves. Her thighs filled out and her hips spread outward taking her jeans with them. Her ass filled out and her feet grew larger as her waist and stomach shifted.

Breasts sprouted and quickly grew large and full as her arms lengthened and strengthened taking her blue top with them.

Melanie’s legs shrank down short and skinny. Her hips and ass went flat and thin as her feet shrank down several sizes in length and width. Her stomach and waist filled out as she lost her mature body and adult curves and her breasts began to shrink away; pulling in until she was totally flat chested as a 10 year old.

Addison now towered over Melanie by nearly a foot in height as they watched their faces change into the ones they had just been looking at in the mirror.

Addison’s face matured and grew as her hair cascaded down long and luxuriant.

Melanie’s face became youthful and immature; her features shrinking and changing into those of a child once again along with her hair losing its luster and body.

Melanie turned slowly to the mirror in shock. Her body now matched the reflection perfectly.

Addison too turned slowly toward the mirror and saw that her reflection too now matched that in the mirror. There in the room and in the mirror stood a 30 year old next to a 10 year old but now it was Addison who was 30 and Melanie who was 10.

“Hey”

“AH!” they both screamed in unison and jumped around to face the door. It was Alan standing in the doorway.

“Sorry I scared you two…I just wanted to see Melanie’s room too”

“MY room?!” Melanie said putting her hand to her chest.

“Yeah” he said as he walked further into the room. He walked up to Addison and took her hand “Hey Babe…just wanted to see what was so cool up here”

Mark now stood in the doorway behind them. He walked in and put his hands on Melanie’s shoulders “Come on birthday girl…everybody’s waiting for you downstairs. Leave your Aunt alone and come downstairs so we can all eat”

“But…but…” Melanie tried to protest as she was led out of the room by the man who was no longer her brother, but her Dad.

Alan leaned over and kissed Addison on the lips. Addison was surprised yet thrilled as she kissed her boyfriend back: Her hands wrapping around him in an embrace.

“I really like your family Addy” Alan told her.

“Thanks…they are pretty cool aren’t they?” she replied with a wicked smile.
