Rebecca Young straightened out her dress, smoothing it down as she got it into place. She made sure the straps on her shoulders were straight, her breasts were situated and the bottom hem was level.

She sat on the edge of her bed as she slipped her feet into the 3" nude heels. They went best with the tight blue dress she had on.

She snapped on her bracelet and put in her earrings as she walked to her antique full stand mirror for one last hair and makeup check.

28 years old with long chestnut brown hair and big brown eyes, Rebecca was stunning. Full pouty lips, a button nose, long eyelashes and striking eyebrows; Becca was 5'9 with long legs, a pert ass and nice perky breasts.

She had a date tonight with a new guy she was hoping to impress.

The mirror was a stand alone in heavy oak; it had been her Grandmother's.

She took small steps, still adjusting her dress over her bubble ass as she stopped in front of it.

"AH!" Rebecca yelped. She jumped and stumbled, her left ankle buckled but she caught herself and balanced. But her heart was pounding from the shock of her mirror.

She had scared herself with what she had seen stepping in front of her mirror.

The reflection wasn't matching herself.

She shook her head and looked again. Rebecca's jaw dropped. The reflection hadn't changed. It was off in the most peculiar way. The reflection was her Mother.

Susan Young looked back from the mirror with an expression of absolute shock. Her jaw opened as she got closer in step with how Rebecca was walking up.

Susan had on a comparable outfit to the one Becca was wearing. The heels were nude but were peep toe and they only had a blocky 1" heel on them.

Her dress was the same shade blue but floral and mixed with white accents. Something very much in her Mom's style.

Rebecca's dress was a size 2. Her Mom's would be 16.

Rebecca looked at her Mom's much larger bust. Her round stomach, her wider hips and hefty ass along with her thicker legs. The dress was knee length, just like her own and Rebecca saw her Mom's thick calves reflected back.

She could easily make out her Mom's pink toe nail polish too.

Rebecca's heels were closed toe but as she wiggled her toes inside her heels, her Mom's toes moved in the mirror.

Her eyes trained upward. Up to her face.

She moved her face left and right seeing her Mom's face move in perfect tandem with her.

Susan was 59. Her face was much fuller of course, her neck thicker, her chin and jaw softer, her cheeks rounder and sagging.

Rebecca looked at her Mom's thinner lips; done in a pink blush lipstick as opposed to her red.

She bared her teeth and saw her Mom's slightly crooked teeth.

Her Mom's larger nose, her Mom's blue eyes complete with lines etched in.

Her Mom's light colored thin eyebrows on her Mom's lined forehead, topped off by her Mom's thin, light blonde hair.

Becca moved her hair aside and saw even her ears and earrings were different in the reflection. "Mom" she finally said, watching her Mom's mouth move silently on the word.

Rebecca crossed her arms and stuck out her hip "What the Hell is going on?"

Three States Away…

Susan Young was getting ready to go out on a date. She had been divorced for years and was going out tonight for the first time with a guy she really wanted to impress.

She smoothed out her blue and white floral print dress before she slipped her feet into her nude, peep toe 1" nude heels. She lifted her pink painted toes to stretch out the tops just a bit.

She put on her bracelet and slipped on her earrings as she headed to her mirror for one last hair, makeup and outfit check.

The mirror was a new arrival from her Aunt Joan's estate. The mirror was a stand alone antique. Susan's Mother had one exactly like it but she had given that away to her daughter Rebecca.

Susan fluffed out her shoulder length light blonde hair as she crossed the room.

"Ah!" She gasped and jumped as she looked into the mirror.

Her hand flew to her mouth in shock as her jaw dropped and her heart pounded in her chest.

"What in the world…" she managed to say upon seeing the reflection.

The reflection didn't match herself. The reflection, somehow, some way, was her daughter Rebecca.

Slowly and curiously, she stepped closer to the mirror. The reflection matched her every movement; from her almost tip toeing steps to her shocked facial expression.

The reflection was wearing a comparable outfit but of course in her daughter's style.

The dress was the same shade of blue but only blue; and super tight as to show off her young, gorgeous body.

The heels were nude but with closed toe and much higher, 3" narrow heels.

Her legs were trim and slender, her hips slim, her ass was pert and a perfect bubble. Her stomach was flat and her bust was much smaller.

1" straps covered her shoulders instead of her own full short sleeves. As she looked at the face. It was absolutely her daughter's pretty and youthful face reflected back.

Big brown doe eyes with thick lashes and bold eyebrows. A tiny, button nose. Full pouty lips in red lipstick instead of her own blush color.

Her neck was flawless and she had none of the excess softness that Susan had on hers or on her chin and jawline or cheeks.

She saw her Daughter's long chestnut brown hair and she moved it aside to see that even her ears and earrings were different.

"Rebecca?!" She said seeing the reflection silently mouth the word along with her.

Susan lifted her foot and waved it back and forth, watching the reflection do the same thing but with a much trimmer leg and a more delicate foot and heel.

She folded her arms across her chest and jut her hip out "What the heck is going on?"

"Is this some kind of prank?" Susan said, looking around the back of the mirror.

She stood before it and smirked. The reflection returned the look "What if?" Susan said.

Rebecca was just confused and puzzled by the mirror "Is this some kind of prank?" She said looking around the mirror.

She shook her head as a thought popped into her head "What if?"

It made her stop and think. "What if I switched bodies with my Mom? What if that was what I looked like? What if the reflection was true? What would it be like if our roles were reversed? What if I were her and she were me? What if were her Mom and she was my daughter? What if she looked like me? What if she had my body and I had hers?"

Rebecca was revolted by the intrusive thoughts. "God No! Where the Hell are these thoughts coming from?! What the Fuck is wrong with this stupid fucking mirror!"

Susan stood before her mirror "What if I switched bodies with my daughter? What if that really were my body and face in the mirror? What would it be like if she were my Mom and I was her daughter? What if she looked like me? What if she were the older one and I was younger? What if our ages flipped? What if I had her body and she had mine?" Susan paused "Ungrateful little bitch. It would serve her right…make her see what it's like to be me"

"What if she's seeing this too?" They both thought. "What if she's standing in front of her mirror right now and seeing me looking back?"

While Susan laughed at the thought, Rebecca felt a cold shiver.

Susan couldn't pull herself away. She stepped closer to the reflection. She could see every small detail of Rebecca's face.

Rebecca stepped closer to her mirror. She could see every little detail on her Mom's face.

It felt like she stared into her Mother's face for a long time before finally blinking. Rebecca stepped back and turned away. She went to her closet and stopped dead in her tracks "What?!" She couldn't even comprehend what was going on. There, hanging in her closet were her Mom's clothes.

"What? Where are my…?!" She looked at the ground; all of her shoes had been replaced by her Mom's shoes.

In a daze, Rebecca stumbled to her dresser. She yanked open the top drawer "Ah!" Escaped her lips as she numbly reached in and pulled out a bra several sizes too large for her. But it was her Mom's size.

"No…what the actual Fuck?" Rebecca was numb. She opened the next drawer. Her underwear was gone; replaced by larger ones in different styles…all old.

Her socks. Her shorts. Her shirts. Her pants.

"No, no, no, no, no…" she mumbled and staggered to her bathroom.

"AH!" She jumped and screamed again upon seeing the reflection of her Mother had followed her to the bathroom mirror.

Thin blonde hair, blue eyes, wrinkles looked back at her.

Looking at the counter, everything had changed there too. Her perfume was cheap and made for old ladies. All her lotions and skin regime…replaced. Her makeup was basic. From a drugstore at best. Even her hairbrush was different.

Her jaw hung open as she picked it up and saw it was full of blonde hairs.

Susan stared at the reflection of her daughter for a long time, staring into those big brown eyes.

She shook her head and took a step back and turned away from the mirror.

Her open closet caught her eye.

The clothes hanging there were different "What in the world?" She stepped softly towards her open closet doors and gasped upon seeing what was there "Those aren't my clothes…those look like, Rebecca's clothes"

She looked down "Those aren't my shoes either!" She grabbed a slim, impractical 4" strappy heel that would lace up over her entire calf in silver "Those must be Rebecca's heels too…all of her shoes"

Curiosity led her to her dresser drawers. She blushed and blanched seeing the things that were now hers; thong panties, lace, satin bras in a very modest 34B

Her socks. Her shorts. Her tops. Her pants; all different. Aluch smaller and much more stylish.

Susan even found bikinis instead of her black one piece swimsuit.

"I just don't understand any of this" Susan said.

She found herself wandering aimlessly in her confusion to her bathroom.

She jumped and gasped as her hand flew to her chest in shock. The reflection of her daughter had followed her to the bathroom mirror.

Susan noticed her countertop. Several different chic perfumes, very expensive lotions and moisturizers let alone the vast array of makeup that littered the entire surface.

She leaned down and saw an item that hadn't been in her bathroom in about 8 years; a box of tampons.

She picked up the circular hairbrush and noted the chestnut brown hairs entwined therein.

Susan plucked a single long hair out and held it between her fingers.

Rebecca staggered out of the bathroom. As she stepped from tile to carpet through the doorway, she screamed.

Her whole room was now different. The paint on the walls was a pastel green. A green and white floral print comforter sat atop a bed with a heavy oak headboard. Her dresser matched perfectly; it was all the furniture her Mom had owned for decades. "Aaaaaahhhhh! What's happening?! Why is this happening?!" She froze and the room was still and silent.

Rebecca felt an ominous presence. She turned to the full length mirror. The reflection of her Mother was still there but was now independent.

Rebecca walked to the mirror but the reflection stood looking straight ahead with her arms folded and a self-satisfied smirk.

A chill ran through Rebecca as she came to a stop.

Rebecca was perfectly still yet she felt movement in her toes. She could hear a faint sound of leather stretching and she went cold as her stomach dropped.

She didn't want to look down, yet she couldn't help herself. She had to look, she had to see.

Rebecca's toes felt pinched and as she looked, she could see their outlines become pronounced in her heels; almost as if they were growing.

"No" she barely managed in a whisper. Rebecca looked down.

Her feet were quaking; quivering and trembling, straining the sides as her toes squeezed tighter in the ends.

Rebecca could see her toe cleavage becoming more evident. Veins and lines popped out atop her feet. Her elegant 3" heels no longer felt like they fit her. And she knew why.

In a burst, everything changed. She spread her toes instinctively as she felt them freed from the pressure. But at the same time, she felt herself drop and she took an impact on her heels.

She heard a squeak coming from her shoes "AAAAAHHHH!" She screamed out seeing what had happened.

Visible were her toes. Painted bright pink, bigger and wider, rougher skin. All there in her tan, open toed 1" heels. Rebecca had her Mom's feet and her shoes.

She gasped in horror at the sight of her feet even as she swirled her ankle and pointed her toes.

Susan walked out of her bathroom numb. She was dazed but upon crossing from the tile to carpet, she felt another wave of premonition wash over her. "Oh jeez!" She exclaimed seeing all of her furniture and decor had changed. Even the color of the walls was different and the room was much smaller.

She spun towards the mirror and once again saw the reflection of her daughter there. But as Susan walked towards it, the reflection was now independent of her movement.

The reflection of her daughter pouted in the mirror with her arms folded over her chest.

Susan came to stop before the mirror. She froze up and stood very still, she sensed something building, some otherworldly sense.

Her feet began to tingle and she immediately looked down.

Susan saw her thick pink toes peeking out as usual but in the blink of an eye, her nail polish turned to black causing her to gasp.

Her toes quivered, shivering as they began to shrink.

They slimmed and pulled back from the ends slightly as the skin there smoothed.

Her heels slipped away from the ends of her shoes as her feet narrowed and thinned.

The tops went smooth as veins and lines dissipated as she felt her toes pinch together.

Her heels suddenly rose up. Her shoes tightened on her feet as the ends closed up and Susan found herself wearing designer 3" nude stilettos.

Her ankle and calf muscles strengthened along with the ligaments and tendons running along the bottoms of her feet.

Susan allowed herself to savor the feeling. The awe and wonder of what was actually happening was overwhelming.

Rebecca felt wave after wave of differing emotions washing over her. Fear being chief among them but also confusion, revulsion and despair. Those were all followed by anger, resolve and stubborn tenacity to beat whatever was causing this.

"Oh God" Rebecca covered her mouth as she tasted bile rise up. She lurched as her body gave a quick spasm and convulsed.

A weight started to settle on her and weight was what began to build on her too.

She heard it as she felt it. A stretching of fabric sounded as her hips, ass and legs all started to thicken and spread.

Initially, it felt to Rebecca like she was tensing up all the muscles on her lower half as everything went tight and rigid.

But then, that rigidity started to yield and grow soft and pliant as fat built up, stretching her skin out.

Her lower legs began to age. Marks and spots of discoloration appeared as her calves thickened. What had been separated came together as her legs touched.

Rebecca's dress grew tighter and tighter as her thighs plumped up and filled out fuller and thicker.

"Shit" she said through her gritted teeth.

Her stomach growled loudly and she looked down. A lump appeared off center to the left. Another grew out slightly higher on the right.

The section between them bubbled up, pushing her blue dress out.

Rebecca's dress had started out skin tight. Now that she was gaining weight and thickness as her body transformed into her Mother's more matronly build, it was getting unbearable.

Rebecca's breathing was getting shallow as her clothing constricted.

She looked down though and knew she was nowhere near her Mom's size yet; she still had a lot more growing and gaining to go.

Susan's legs began to strengthen, tighten and lengthen. Her ankles trimmed and her calves began to slim as her muscles clenched and shrank up smaller yet stronger.

To Susan, it felt like all of her leg muscles squeezed and strained all at once.

She could feel a euphoria rise in her. A sensation she had never felt before that was hard to describe as her body began to physically transform into her daughter's body. So familiar yet so foreign.

She felt her whole body quake and quiver and she tensed, almost crouching in anticipation. Her stomach growled and gurgled loudly, then spasmed and sucked inward in a lurching contraction.

She felt her hips and ass pucker and begin to narrow and shrink along with her thighs and stomach.

Her dress loosened, fluttering slightly outward as she shrank away inside it.

Susan felt it shift on her shoulders. A thought popped into her head "This old dress will never fit me ever again. I'll never be this size. Not even when I get this age again, many many years from now"

The independent reflection looked angry but Susan had a devilish smile on her face.

Her thighs were slimming and she could feel them separate.

Susan let out a low moan of pleasure as her thighs firmed up. Her hips were narrowing, creaking audibly as they pulled in.

She could feel popping sensations breaking out across her ass as the fat crackled, being broken down.

As it shrank, she could feel her skin pulling taut, tightening and smoothing out.

Susan's whole body was shrinking away.

Her soft stomach pulsated as it pulled inward.

The reflection of Rebecca was seething but Susan merely smirked at it.

Rebecca felt her chest constricting. The zipper on her dress gave way allowing some release.

Rebecca was disgusted feeling her zipper push down due to her back expanding out wider and fatter.

The straps of her dress were tightening on her shoulders as her breasts now began to grow.

Rebecca almost threw up seeing her perfect breasts first turn pasty white, then begin to dimple and wrinkle and sag as they begin simply spreading; growing larger on her chest.

The dress was being pushed outward in a dozen different directions. Just when Rebecca was sure it would split apart, she felt a puff of air and her dress changed shape, size and color into her Mom's dress.

Rebecca saw it on her; still a bit big and loose but undeniably Susan's.

Blue and white floral; size 16 and she was growing into it. Her upper arms and breasts were covered but she could see and feel the fabric lifting and moving as her body expanded. She could feel that she had also gained a bra; her Mom's huge bra, now on her body, a body that was changing into her Mom's body. Breasts that would soon fill it to capacity.

She took in a deep breath and screamed in frustration and rage as the reflection mocked her.

Susan's hands went to her stomach and she pressed down as her soft belly shrunk down and firmed up, pulling in flat and feeling strong.

Susan shivered and giggled as she felt her breasts twitching.

The sensations that exploded throughout her body as her breasts shrank were earth shaking. She had never felt anything like it in her 59 years. Mouth watering, spine tingling; it felt like her breasts were being massaged and squeezed as they rose up and firmed up as so much age, sag and excess fat vanished.

Her dress and bra were useless; her pert and perky breasts sat high all on their own nowhere near the bra cups.

Susan could push her dress back and down; it was huge on her dwindling frame.

Her upper arms now slimmed down and just as she took in a deep breath, she felt a sudden tightness on her body  and looking down, she jumped and gasped.

Her dress was now skin tight and bright blue. It was Rebecca's dress. And it fit.

"Oh my God! I'm skinny!" She squealed happily. "And young!"

"Oh my God! I'm fat!" Rebecca yelled "And old!"

She felt her sleeves growing tight as her fat upper arms expanded outward.

Her breasts slid steadily out, filling up her 44DD cups. Her nipples touched the outer rim, quickly smushing up as flesh continued building up.

She filled out her big bra. Her dress was getting snug.

She heard popping and crackling as fat pockets popped out growing her ass even bigger.

Rebecca could feel the weight. She could feel her body spreading out wider, inflating larger.

The changes now made their way down to Becca's hands. Where her feet had grown, her hands now shrank.

Rebecca's hands trembled as her palms thickened and her fingers shortened. "Aaaaaahhhhh…" escaped her lips as her nails widened and pulled down, losing her extra length. Blemishes and wrinkles and creases appeared all over her older hands.

Susan's body was tightening up, smoothing off the rough edges. The last few pockets of excess fat and saggy skin were finishing up. Her inner thighs clenched. Her final pop in her tight ass made her jump and giggle. Her breasts twitched one more time as they settled in and her hands ran from her flat stomach to her stable, narrow hips.

Her arms were changing and she watched her forearms adjusting and she lifted her hands in time to see their modifications.

Instead of shrinking, they now grew longer and more elegant. Her palms thinned and the backs smoothed. Her fingers elongated and her fingernails pushed out longer. She clicked them, feeling their strength as they grew.

The skin there, previously rough, now shined with a glossy glow. Black nail polish filled in, giving her hands a bold, striking look.

Susan felt the skin on her neck pulling taut.

She stared at the mirror in front of her that now started to waver. The reflection of Rebecca looked shocked as it then vanished; replaced by what was her true reflection for the moment. Her head and her daughter's awesome body. She wanted to see this.

Rebecca was dreading this. This was the absolute worst thing that she could think of happening to her.

As the changes reached her neck. She saw the reflection of her Mother. It leaned forward and gave a passive aggressive little finger only wave with a self-satisfied smirk just before it vanished and Rebecca was confronted with her true reflection for the moment; her face on her Mother's dumpy body.

"Oh Jesus! What the fuck is this?! This can't be happening to me!" She cried out as the skin on her neck loosened and drooped.

Her chin weakened and sloped inward, taking her whole jawline with it.

Her eyes pleaded against the changes already taking effect. Her walk chin and jaw now dragged her mouth down at the corners. Lines etched in as her lips thinned.

She could already see her Mother coming out.

Her lips parted even as they pulled down, exposing teeth that were shifting and moving places. Her tongue flicked against her sliding teeth.

Rebecca's nose grew larger as her cheeks somehow both filled out bigger and drooped at the same time.

Her big brown eyes began to narrow down, shrinking as the color drained from them down to a pale blue.

More lines drew in deep at the corners of her eyes as bags puffed out. Her eyelashes thinned as her brows and forehead shifted.

Her dark, bold eyebrows thinned and lightened down to nothing as more long age lines appeared.

Rebecca's long, thick dark brown hair now began to change as well. The last item of her own; it pulled up shorter, grew thinner and lightened in color to a lackluster blonde in her Mother's style.

The reflection in her mirror was her. She had turned into her own Mother down to her clothes. The reflection matched her look of absolute shock and horror down to her slightest twitch.

Susan's chin came out forward, shifting her jawline to a more prominent position.

Her face seemed to glow as her skin revitalized. The lines and spots and blemishes disappeared, vanishing into thin air as her lips plumped up full and pouty.

Her teeth whitened and straightened and strengthened as her tongue pulsated as it changed.

Her nose shrank down button pert as her cheeks streamlined out to sleek prominence.

Her eyes rounded and grew doe like as they turned a deep brown with long thick lashes.

Gone were her forehead lines and eye bags. Replaced with bold, dark eyebrows that arced perfectly just as her thin blonde hair took off.

It grew long, thick and dark brown completely changing her look to that of her daughter.

Even her jewelry had changed.

Susan looked in her mirror and saw her true reflection that now matched her every movement. She had turned into her own daughter, down to her clothes.

Rebecca just stared at her reflection as her hands now started to move about, touching and probing her soft body, her older face.

"No…no, no, no,nononononono!" She said in a now deeper voice; her Mom's voice.

She turned around, feeling how differently her body moved, the weight of it, the different center of gravity, the way parts kept moving.

Her thick feet in her low heels taking tiny steps.

Rebecca was in her Mom's house, in her Mom's body, in her Mom's clothes, in her Mom's life.

"Mom?" She croaked out and her head began to swim and everything went blurry.

Susan's hands and eyes began to explore downward "Ohmygod! Oh my fucking God!" She laughed gleefully "I am so fucking hot!" She added in her higher pitched, more youthful sounding voice, Rebecca's sweet voice.

She took small, mincing steps in her super high heels and super tight dress. Susan was in her daughter's apartment, in her daughter's body, in her daughter's clothes, in her daughter's life.

"Hi…im Becca" She giggled as she felt her head swim and her world swirled around her.

When Rebecca came to, things had settled down. She couldn't explain it yet she knew she had to go on this date as her Mom, as Susan. She couldn't see the future but somehow she knew this was her now. She swore she could hear her Mom laughing in her head.

Susan laughed as she realized that she was getting ready to go on a date as her daughter, as Rebecca; as herself.

She knew she was never going back.

The doorbell rang. Pivoting on a heel, they both stepped forward to meet their dates.
