In an eighth-grade class, a group of students were excitedly talking about what they were going to do for thanksgiving break. In the back of the class sat Nancy Elk, a young girl suffering from an onset of acne, who was somewhat distant from her other classmates. She had layered black hair that was styled in a bob cut, her bangs hid her onyx eyes from view, and she had a red hairclip in her hair. She had dark glasses that had plastic tips, and she was wearing a navy-blue blouse and a blue skirt. She had on a pair of black mary janes and white socks that reached all the way up to her knees.

‘Just ten more minutes.’ Nancy thought to herself as she stared at the clock above the blackboard. ‘Ten more minutes, and then I can leave.’

She watched the clock tick down, and barely paid any attention to what the teacher was saying. Once the school bell rang, Nancy leapt up from her seat and pushed her way to the front of the class.

“By the way everyone, don’t forget to turn in your essays by Thursday!” Nancy’s teacher called out. Nancy ignored him as she rushed out into the hall and dashed out of the school’s front entrance. As she ran home, a smile bloomed on her face as she looked forward to what was waiting for her back home......

When Nancy got home, she noticed a brown box on the front porch. She smiled and grabbed the box before she rushed inside. She said a quick hello to her mom as she raced up to her room and locked the door behind her. Nancy tossed the box onto her bed and opened the flaps, revealing a costume that she had bought online.

The costume comprised of a white leotard-like bodysuit with lilac accents, along with a white choker that had a lilac button in the center and white boots that had lilac accents running down the tips. In a few hours she’d go to a convention, and she wanted to look her best.

Nancy took the leotard out of the box and held it in front of her. It was kind of big, but Nancy figured that she could wear something on top of it and then no one would be able to tell that the leotard didn’t fit quite right. She gingerly stepped into the leotard and then pulled it up her body, she forced the straps over her shoulder. After that, she grabbed the boots out of the box and put them on, the long boots reached all the way up to her upper thighs, and she struggled to keep her balance as she grabbed the white choker out of the box and brought it over her head. She glanced at herself in the mirror and winced. She looked awkward, the costume was clearly too large for her, she was just a tiny slip of a girl wearing something that was three times her size. Luckily though, the store that offered the costumes had a special function that would allow any piece of clothing to fit a person of any size. After grabbing the boots and the choker out of t

“Where is it?” Nancy asked as she ran her hand up and down her back. “There’s supposed to be a button here...ah-ha!”

Nancy felt the button on the back of the leotard and pressed it. The leotard let out a hiss of air as it shrunk to properly fit Nancy’s body. In a few seconds the leotard was snuggly pressed against her body, and now Nancy didn’t appear as awkward as before. There was another problem though, and it was one Nancy would soon find out as the leotard continued to press against her body, causing her curves to be fully pronounced.

“It’s....kind of tight.” Nancy said as she stared at herself in the mirror. The leotard was flush against her skin, and she couldn’t even pull it an inch away from her skin. She winced as the leotard snapped back onto her arm and sighed. She should’ve been a bit more careful putting the leotard on, after all she didn’t know if it was some kind of trap by whoever sent the leotard. As she glanced at herself in the mirror she saw that a button in the center of the white choker was glowing. The words ‘OFF’ were written on the button in white, blocky letters.

“Oh, I guess I just press this to get the leotard off.” Nancy said. She pressed the button and then....nothing happened.

Nancy frowned. “Is this thing broken?”

She pressed the button again and again, but the leotard was still as tight as ever.

‘Great, they just had to make a button that doesn’t work.’ Nancy thought to herself. ‘Maybe I should go downstairs and get mom to hel-’

Nancy paused as she caught a glimpse of herself in the mirror. While she’d been struggling with the buttons, her bangs had been pulled up, revealing her eyes. Nancy wasn’t sure if it was just the lighting playing tricks on her, but her eye color seemed to be getting lighter. Her pupils were also undergoing a sudden change, they twisted and morphed as they transformed into power symbols.

“I must be hallucinating.” Nancy said. It was the only rational explanation her brain could come up with. Because of how tight the leotard was, it must have been cutting off the air supply to her brain and now she was seeing something that could only happen in a story or some sci-fi film. “Yeah, I’m definitely hallucinating.”

Nancy’s spine began to lengthen as the transformation kicked in, and Nancy’s height began to increase. A wave of pure relaxation ran down Nancy’s spine, and she let out a content sigh as the tension in her muscles washed away. Her skin paled somewhat, and the acne on her face faded away, leaving her skin silky smooth.

“Wow.” Nancy said as she ran a hand down her cheek. “It’s....so soft!”

As the transformation continued, the boots moved further and further down her legs as her height increased. Her legs slimmed down and toned as her feet cracked and lengthened to fit her boots. As her legs grew her thighs pulsed, causing Nancy to let out a soft moan. Her thighs slowly expanded outwards, growing in size and gaining a distinct curve. Once Nancy’s height had increased by about two feet, the boots had ended up at her mid-thigh region. They pressed tightly against her thighs, causing them to jiggle slightly as her hips expanded outwards. Her rear bubbled out in size and pressed tightly against the back of her leotard as her waist drastically shrunk in size. Another wave of relaxation ran down Nancy’s spine as the next stage of the transformation began. Her sides pushed inwards, giving her an hourglass figure as her torso slimmed down. Her navel lengthened, and due to the tightness of the leotard her lengthened navel was made easily visible through her clothing. Nancy’s height stopped increasing, leaving the young girl at the height of a teenager.



“Ngh...” Nancy grunted as she felt a pressure begin to build up within her breasts. Her areolae expanded as her nipples hardened and became impressions against her leotard. Her leotard began to tent as her breasts ballooned outwards, due to the open area over her chest her cleavage was easily seen as her breasts grew larger and larger. Her shoulders cracked inwards, and her arms began to lengthen down her sides. White gloves appeared in front of her and gently pulled themselves over her hands and pushed all the way up to her elbows. Her choker softened as it tightened on her neck before it attached itself to the top part of the leotard, leaving enough space to form a ‘boob window’. With one last surge, her breasts stopped growing once she was busty enough, if Nancy had to guess she was about a D-cup, though her breasts were possibly larger than that. Her large cleavage was on full display as the transformation reached her head. Nancy’s vocal cords matured as her lips thinned and her nose shrank in size. Her eyelashes became more pronounced as her eyes grew larger and appeared a bit more anime-esque. Her pupils became a pure shade of white as her eye color became an electric shade of blue. Her eyebrows thinned as a light blush formed on her cheeks, and her hair lengthened down her back in waves. Her bangs swept to the side as white, round hairpiece with a blue center formed in her hair. Lilac dye that had a slight pink tone rushed down the roots of her hair, dramatically altering her hair color as the transformation ended...
