Her Curves

Chapter 5 - Greed and Envy

Written by: GrowthGooru

The bathroom door groaned loudly as it swung open.

For a brief moment, nobody outside seemed to understand what they were looking at.

Then Holly stepped through first.

The hallway fell silent.

At 6'3, she towered over nearly every student in sight. Girls who had once stood eye-to-eye with her barely reached her shoulders now. Even most of the men scattered throughout the corridor found themselves looking slightly upward as she emerged. 

A second figure followed.

Kiki.

At 6'9, she had to duck to leave the bathroom doors. The movement alone drew dozens of eyes. She seemed impossibly large inside the cramped academic building. The overhead lights that had always felt comfortably out of reach now appeared alarmingly close above her head. Every step she took seemed to command attention without effort.

Then Anita emerged behind them, lowering her head slightly beneath the frame as well.

At 6'6, she stood squarely between the other two in height, but her broader shoulders and fuller frame gave her an imposing presence all her own.

The trio stood together for only a second.

But it was enough.

Every student in the corridor stopped what they were doing.

Phones slowly lowered.

Backpacks slipped from shoulders.

Conversations died in unfinished sentences.

The three women looked around.

And realized everyone was staring.

A slow smile spread across Anita's face.

"Well," she said, folding her arms, "this is awkward."

Nobody laughed.

Nobody moved.

The silence only made the moment feel larger.

Holly glanced down the hallway.

Students were lined almost wall-to-wall.

Some looked shocked.

Others looked fascinated.

A few simply looked confused.

"What are they looking at?" Holly asked.

Kiki snorted.

"Seriously?"

Holly laughed despite herself.

“Let’s get going, we can stay at my place while we find some clothes that fit,” Anita said confidently.

“What about class?” Holly looked up at them, blushing.

The simple act emphasized the difference between them. Standing beside Anita and Kiki, Holly suddenly found herself looking up more often than she ever had before.

“Screw class,” Kiki said.

“Yeah, fuck that. The professor would kick us out anyways for being naked,” Anita said, looking down at Holly as she bit her lower lip anxiously.

Then the three women started walking.

The crowd immediately parted.

Their footsteps echoed heavily across the tile floor as they moved through the building. The hallway suddenly felt too small. Ceiling panels seemed lower. Doorways seemed narrower.

Everywhere they looked, students were staring.

Some openly.

Some pretending not to.

Most failing miserably.

Anita couldn't stop grinning.

The attention followed them like a wave.

As they passed classroom windows, professors paused mid-lecture.

Entire groups of students abandoned conversations to watch them walk by.

The farther they went, the larger the crowd became.

Word was spreading.

Fast.

By the time they reached the main academic lobby, dozens of students had fallen in behind them.

Then dozens became hundreds.

"What is happening?" Holly muttered.

"I think we're trending," Kiki replied.

Anita laughed.

The sound echoed through the lobby.

A pair of campus security guards hurried toward them from across the room.

The older guard raised a hand.

"Excuse me, ladies!"

The three women continued walking.

"Excuse me!"

Still walking.

The guards exchanged uncertain glances before increasing their pace.

"Misses, we're going to need you to stop."

That finally got Anita's attention.

She glanced over her shoulder.

The guard abruptly realized he was looking up.

Way up.

For the first time, he seemed unsure of himself.

Anita tilted her head.

"Why?"

The question wasn't hostile.

It somehow made the situation more intimidating.

The guard opened his mouth.

Nothing came out.

Because honestly, he wasn't entirely sure anymore.

They hadn't broken any rules.

They were just...

Huge.

The second guard cleared his throat.

"We'd just like to ask a few questions."

Anita considered that.

Then shrugged.

"Maybe later."

And kept walking.

The guards watched them leave.

Neither attempted to stop them.

Outside, the afternoon campus buzzed with normal activity.

Students crossed sidewalks.

Cars moved through nearby streets.

People lounged on benches beneath the warm spring sunlight.

Then the front doors opened.

Everything changed.

Conversations stopped almost instantly.

Heads turned.

One by one.

Then all at once.

The three women emerged onto the main campus walkway.

The reaction was immediate.

People stopped walking.

Entire groups turned to stare.

A cyclist nearly rode into a trash can.

Someone dropped a coffee.

Another student simply stood frozen with their mouth hanging open.

The scale was impossible to ignore.

Holly towered over most students.

Anita matched or exceeded the height of many male athletes she'd once looked up to.

And Kiki...

Kiki stood above everyone.

Even from halfway across the quad she was impossible to miss.

The crowd parted automatically as they approached the front gates.

Nobody asked them to move.

Nobody wanted to stand in their way.

Hundreds of eyes followed them.

Phone cameras appeared everywhere.

Videos were already being uploaded before they'd crossed half the quad.

Kiki looked around slowly.

"This is insane."

Holly nodded.

"A little."

Anita looked positively delighted.

"No," she said.

"This is amazing."

Far across campus, seated alone in a lecture hall, Miya stared down at her phone.

Notifications flooded her screen.

Photos.

Videos.

Messages.

Rumors.

Questions.

And the worst part?

Jenna still had no idea of just how big they had grown.

—

Jenna sat on the edge of her bed for several moments, staring at the darkened doorway across the room.

The frame looked smaller than she remembered.

Everything did.

Her desk.

Her dresser.

Even the posters hanging on the walls seemed lower than they had this morning.

The realization settled heavily in her chest.

She was changing faster than she'd planned.

Much faster.

With a frustrated sigh, she pushed herself upright from the mattress. The bed springs groaned in relief as her weight left them.

"Okay," she muttered. "I need to find some clothes that fit."

That was becoming a real problem.

She crossed the room and yanked open her closet.

Rows of shirts, jeans, sweaters, and jackets greeted her.

None of them looked promising.

Jenna grabbed an oversized hoodie first.

Yesterday it had hung loosely on her.

Now the sleeves barely reached her wrists, and the hem sat awkwardly above her hips.

She stared at herself in the mirror.

"...Great."

Off it came.

Next was a sweatshirt.

Too tight across the shoulders.

A pair of sweatpants.

Too short.

Another shirt.

Too small.

Ten minutes later, half her wardrobe was scattered across the floor.

Jenna folded her arms and glared at the mess.

"I shouldn’t have taken more earlier," she grumbled. "I took way too many drops."

Then she stopped.

A familiar warmth rolled through her body.

Her expression immediately changed.

"No."

The tingling spread down her spine.

Across her shoulders.

Through her legs.

She looked toward her bedroom door.

The top of the frame seemed slightly closer.

Just slightly.

Maybe an inch.

Maybe less.

But enough to notice.

Enough to make her pulse quicken.

The warmth intensified.

Jenna stepped toward the doorway and stopped directly beneath it.

Her eyes widened.

The clearance looked tighter.

Definitely tighter.

"I'm still growing."

Her phone buzzed violently on the bed.

She nearly jumped.

Snatching it up, she found several messages waiting.

Miya:
“JENNA!”

Miya:
“CALL ME!”

Miya:
“OR TEXT ME!”

Miya:
“YOU WILL NOT BELIEVE WHAT HAPPENED!”

Jenna immediately typed back.

Jenna:
“What happened?”

The response arrived almost instantly.

Miya:
“Anita and her two friends left campus.”

Miya:
“They walked right through the main building.”

Miya:
“Everyone was staring.”

Miya:
“Security tried talking to them and they completely ignored them.”

Jenna frowned.

Jenna:
“Okay?”

Miya:
“They were HUGE!”

Jenna rolled her eyes.

Jenna:
“Relax.”

Jenna:
“Don't worry about them.”

Three dots appeared.

Then another message.

Miya:
“I think they're bigger than you.”

Jenna blinked.

Jenna:
“That's impossible.”

Jenna:
“I'm still growing.”

Miya:
“I told you they took way more of the serum at once! Wait, how tall are you now?”

Jenna glanced back toward the doorway.

Good question.

Jenna:
“I don't know.”

Jenna:
“I think I grew again.”

Miya:
“GO CHECK!”

Jenna sighed.

A few minutes later she stood in her bathroom once more, measuring tape in hand.

She backed against the wall.

Checked the mark.

Looked again.

Then a third time.

Her stomach dropped.

Six foot six.

She stared at the number.

Only a few hours ago she'd measured six foot four.

Now she was six and a half feet tall.

Another two inches.

"Seriously?"

Her phone buzzed again.

Miya:
“Well?”

Jenna:
“6'6"”

Several seconds passed.

Miya:
“Damn. That's a problem.”

Miya blushed seething with jealously.

Jenna:
“I know…”

Miya:
“Anita looked bigger than that when she left.”

Jenna's grip tightened around the phone.

Miya:
“And Kiki was even taller than them both.”

Jenna swallowed.

Miya:
“I told you they took way more serum than you at once! Their bodies are compounding the growth adaptogen at a crazy rate.”

Miya:
“If they're reacting the same way you are…”

Miya:
“The major growth spurts haven't even started yet, that’s just the first one of many.”

Jenna looked up at her reflection.

The mirror suddenly felt smaller.

The bathroom felt smaller.

The whole house felt smaller.

For the first time all day, genuine concern crept into her thoughts.

Jenna:
“I need clothes.”

Miya:
“That's your takeaway from all of this?”

Jenna:
“Yeah. Nothing fits.”

Miya:
“Oh, yeah I mean… that’s fair.”

Jenna:
“Come to my house after class tonight.”

Jenna:
“We'll figure something out.”

Miya:
“Okay. Deal.”

Jenna lowered the phone slowly.

Six foot six.

And she was still growing.

And apparently no longer guaranteed to be the largest subject in Miya’s now big experiment.

That thought lingered in her mind long after the conversation ended.

—

Across town, Miya sat through the remainder of her evening lecture.

At least, she appeared to.

In reality, she barely heard a word the professor said.

Her thoughts kept drifting back to Jenna.

To Anita.

To her other now amazon-sized friends.

To the impossible transformations.

To the serum she had concocted to help Jenna win some little track race.

By the time class ended, she'd already made up her mind.

An hour later she slipped quietly into the science building.

Most of the campus had gone home.

The laboratories were nearly empty.

Perfect.

She unlocked a storage cabinet and began gathering equipment.

Glassware.

Chemical solutions.

Research notes.

Her hands moved quickly.

Confidently.

She'd spent enough time helping Jenna grow to her huge size to perfect the formula at this point.

The mixture slowly swirled inside a flask beneath the fluorescent lights.

Clear.

Colorless.

Almost harmless-looking.

Eventually, a small vial sat on the workbench.

Miya picked it up.

The liquid shimmered faintly as she turned it in her fingers.

For several seconds she simply stared at it.

Then a nervous smile crossed her face.

"Just a couple doses worth," she whispered.

The vial caught the light.

“Just so… those giant bimbos can’t take anything from me again.”

She lifted the vial and looked at it for a moment.

“Who am I kidding… this is way more than any of them took… but I’m… really tiny… compared to them.”

She wrestled with her thoughts as she heard footsteps down the hallway and quickly thought.

“This is… so reckless.” Before she lifted the vial up to her lips and tilted it all the way.

She took a long gulp, then another, and one more before setting down the empty vial.

“That should be plenty to match those… bitches.” She let out a cute burp and began cleaning up the station quickly to not leave any evidence.

The professor opened the door to the chemistry lab and called out to her.

“Miya? I didn’t know you were staying late tonight.”

Miya forced a smile.

"Oh! Hi! Yeah, I just wanted to double check something. I'm leaving now actually."

The professor nodded.

"Don't stay too late."

"Wouldn't dream of it."

She took a step toward the door.

Then another.

Halfway across the lab, a sudden wave of heat surged through her body.

Her smile faltered.

The sensation spread from her stomach outward, radiating through her chest, shoulders, and limbs like she'd stepped into a furnace.

Miya stopped.

"You okay?" the professor asked.

"Y-yeah."

She wasn't.

Not even remotely.

The tingling intensified.

Her pulse began hammering.

Each heartbeat seemed louder than the last.

The collar of her shirt suddenly felt tighter.

Miya frowned and tugged at it.

The movement made her freeze.

Something felt different.

Wrong.

Or perhaps very, very right.

Her gaze dropped.

The front of her blouse looked slightly fuller than it had a minute ago.

Not dramatically.

Just enough to notice.

"No way..."

Another pulse surged through her body.

Heat rushed through her chest.

The fabric stretched faintly.

Miya's eyes widened.

"Oh, you've gone pale," the professor said. "Do you need me to call someone?"

"No!"

The response came far too quickly.

The professor blinked.

Miya immediately forced an awkward laugh.

"No. No. I'm fine."

A bead of sweat rolled down her forehead.

Her hands trembled.

She could feel the serum working.

Actually working.

The realization was both thrilling and terrifying.

Her heartbeat accelerated again.

The warmth spreading through her body seemed to intensify with every passing second.

"I just need some air."

Without waiting for a response, she hurried toward the hallway.

The moment she stepped outside the laboratory, she grabbed the wall for support.

"Oh my god..."

Her entire body buzzed.

Her arms tingled.

Her legs felt strangely light.

The floor seemed slightly closer.

Or maybe she was imagining it.

She pushed herself forward.

The corridor stretched ahead of her.

Empty.

Thank goodness.

The last thing she wanted was an audience.

Halfway down the hall, another surge rolled through her.

Miya gasped.

The sensation washed through her torso, forcing her to stop beside a display case.

Her reflection stared back from the glass.

Flushed cheeks.

Wide eyes.

Hair sticking to her forehead from sweat.

And a silhouette that already looked subtly different than it had twenty minutes ago.

"That was way too much serum," she muttered.

The realization hit immediately afterward.

She had consumed an entire vial.

Far more than Jenna ever had.

Far more than Anita.

Far more than anyone.

"What was I thinking?"

Humanity's greatest scientific discoveries had traditionally begun with somebody ignoring common sense.

Apparently tonight was her turn.

She hurried toward the building entrance.

The heat refused to fade.

If anything, it grew worse.

Her breathing quickened.

Sweat dampened the back of her shirt.

Strands of dark hair clung to her cheeks and neck.

By the time she reached the front doors, her heart felt like it was trying to escape her chest.

Students passing outside barely noticed the tiny exhausted woman stumbling through the entrance.

Miya pushed through the doors and immediately felt cool evening air strike her face.

For a brief moment, relief washed over her.

Then another powerful wave surged through her body.

She grabbed the railing beside the steps.

"Oh..."

The parking lot seemed farther away than before.

Or perhaps she was simply struggling to focus.

Her limbs felt strange.

Heavy and light at the same time.

The serum continued racing through her bloodstream, transforming her from the inside out.

And judging by the growing warmth spreading through every muscle in her body...

This was only the beginning.

Miya staggered toward her car clutching her keys, completely unaware that by sunrise she might have a very different set of problems.

—

She barely made it to her car.

The moment the door slammed shut behind her, she locked it instinctively and collapsed back into the driver's seat.

Her hands were shaking.

Badly.

The cool leather felt wonderful against her overheated skin.

For about three seconds.

Then the heat returned.

Stronger.

"Mmh..."

She pressed both palms against the steering wheel and took several deep breaths.

It didn't help.

Her pulse continued racing.

Every heartbeat sent another wave of warmth through her body.

Sweat dampened her blouse.

Strands of dark hair stuck to her forehead and cheeks.

She reached up to brush them aside, only for another shiver to run through her entire frame.

The serum was working.

Far too well.

The warmth gathered in her chest.

At first she thought she was imagining it.

Then her blouse tightened.

Miya froze.

Slowly, she looked downward.

Her eyes widened.

The front of her shirt looked fuller.

Not dramatically.

Not yet.

But enough to notice.

"Oh god..."

A tingling sensation spread through her torso.

The pressure built steadily beneath the fabric.

Her breathing quickened.

The snug fit of her blouse became noticeably tighter as her body continued changing.

Miya grabbed the edge of the steering wheel.

"Mhhhnnn..."

Another pulse surged through her.

The sensation intensified.

Her chest felt heavier.

Rounder.

The change wasn't stopping.

Within minutes, the fit of her bra felt completely different.

The tiny A-cup she had worn her entire adult life suddenly felt inadequate.

Compressed.

Too small.

She stared downward in disbelief.

"I just took it ten minutes ago… how is it working this fast–awhn!~"

She moaned and blushed as another wave hit.

Her entire body trembled.

Heat radiated through her arms and shoulders.

Her blouse stretched further across her chest.

The fabric pulled tighter with each passing minute.

Miya's mouth slowly fell open.

Panting hard as blushing bright red in both cheeks as her tongue lolled out onto her lower lip.

The changes were accelerating.

What had begun as subtle fullness quickly became impossible to ignore.

The petite frame she'd known for years was already beginning to look different.

Her heart hammered.

Her breathing became shallow.

She could physically feel her body responding to the serum.

By the time several more minutes passed, the pressure around her chest had become impossible to miss.

The bra she'd put on that morning now felt painfully restrictive.

The cups strained against the increasing fullness.

"Oh my god… they’re growing."

She fumbled with the clasp beneath her blouse and loosened it slightly.

Immediate relief flooded through her.

Followed by another surge of heat.

The serum seemed determined to keep going.

Miya leaned her head back against the seat.

The car felt strangely small.

Not because she'd become huge.

Not yet.

But because every minute seemed to bring another change.

Another surprise.

Another reminder that she'd consumed more serum than anyone else.

Far more.

The realization finally hit her.

Jenna had only taken small doses.

Anita and the others had taken larger ones.

Miya had swallowed down an entire vial.

An entire vial.

"Shit! Why did I take so much?"

The answer was obvious.

Competition.

Jealousy.

Fear of being left behind.

Outside, students crossed the parking lot completely unaware of the crisis unfolding inside the compact sedan.

Inside, however, Miya could feel the transformation building momentum.

The heat wasn't fading.

The tingling wasn't slowing.

And somewhere deep inside her bones, she had the growing suspicion that tonight was going to be much longer than she'd planned.

Miya's hands trembled against the steering wheel.

The heat wasn't fading.

If anything, it was getting worse.

Every breath felt hotter than the last.

Sweat soaked through the back of her blouse as she leaned forward in the driver's seat, trying to steady herself.

“Miya, you absolute idiot…” she muttered, voice shaking.

Another pulse rolled through her.

Harder this time.

She gasped.

Her shoulders jerked slightly as the sensation snapped through her chest and down into her core. Her blouse tightened again, pulling in a way that made her freeze mid-breath.

Her eyes dropped.

“…No way.”

The fabric across her chest pressed tighter than before, as if her body had subtly, insistently pushed outward in the span of seconds. She swallowed hard, fingers hovering uncertainly at her collar.

The next wave didn’t give her time to think.

It just hit.

Miya let out a strained sound and slumped back into the seat, her body trembling as the serum flared through her system like it had finally decided to stop teasing and start committing.

Her chest rose under her blouse with unmistakable firmness, the change no longer subtle enough to deny. The bra she wore pinched uncomfortably now, forcing her to shift awkwardly in her seat as her breathing turned uneven.

“I’m growing so fast…”

Her voice came out thinner than she intended.

Another surge answered her.

Heat flooded her torso and spilled downward.

Her stomach tightened.

Her hips twitched against the seat.

Miya’s fingers dug into the steering wheel as a sharp, spreading sensation ran through her lower body. Her thighs pressed against the leather as if the space itself was shrinking around her.

Except it wasn’t the car.

It was her.

“Bigger… bigger… bigger…”

The sentence broke off into a shaky breath.

Her legs shifted involuntarily, knees knocking slightly against the console as a strange pressure pulled through her frame. It wasn’t painful. It was… expanding. Stretching. Like her body had remembered a different size and was forcing her into it.

Her shoes suddenly felt tighter.

Her ankles flexed.

Then her calves followed suit, muscles subtly lengthening as her posture changed without permission.

Miya stared forward through the windshield, wide-eyed, as her reflection in the rearview mirror seemed just slightly closer than it should’ve been.

“…I’m getting taller.”

The words came out disbelieving.

Then it happened again.

A clean, undeniable surge.

Her spine straightened sharply against the seat as if pulled upward by an invisible force. Her head brushed the headrest differently than before. The angle of everything in the car shifted with her.

Her breath caught.

“I think I just passed the five foot mark…”

The number escaped her on instinct.

The sensation didn’t stop to confirm it.

It simply continued.

Her thighs lengthened further, pressing deeper into the seat as her hips subtly restructured to match the new proportions. Her legs extended just enough that her feet repositioned awkwardly on the pedals, forcing her to adjust in a panic.

The seat suddenly felt small.

Too small.

Too shallow.

Miya’s eyes darted down again.

Her blouse was still straining, but now the strain felt distributed differently across a frame that was no longer as compact as it had been minutes ago.

Her heartbeat thundered in her ears.

Another wave rolled through her.

Her shoulders lifted.

Her torso stretched.

And when it settled—

She exhaled sharply.

“…I’m taller.”

Her voice sounded different saying it.

More distant.

Less small.

The mirror confirmed it.

Her face sat at a slightly higher angle now, her line of sight changing just enough that she had to adjust the rearview mirror without thinking.

“Taller… again…”

Her breath hitched again.

Heat surged through her hips and thighs, pushing her body onward like it had simply decided there was more room to occupy.

Her legs elongated another fraction, pressing her deeper into the driver’s seat. Her knees shifted again, hitting the underside of the dashboard with a muted thump.

“Getting… cramped…”

Miya’s hands shook harder now, one briefly leaving the wheel to brace against her own thigh as if anchoring herself.

Her breathing turned shallow.

The car felt smaller again.

Another pulse.

“Ah—!”

Her spine extended again, forcing her posture straighter. Her head rose closer to the roof of the car, brushing nearer to it than before.

Her hair, damp with sweat, clung to her cheeks and neck as she turned her head sharply, trying to make sense of what was happening.

“Still… growing…”

Her voice wavered.

Her thighs pressed harder into the seat as another adjustment ran through her lower body, reshaping her proportions again. The space between her hips and knees stretched subtly longer, her frame no longer fitting the same way it had just minutes ago.

The steering wheel felt slightly lower.

The roof slightly closer.

The seat slightly too small for comfort.

Miya swallowed hard.

“Even… bigger…”

Her final whisper came out breathless, disbelieving.

Miya sucked in a sharp breath as the next surge hit, her grip tightening on the steering wheel until her knuckles went pale.

She quickly grabbed her keys off the passenger seat and turned the ignition.

The car’s hum began to rumble throughout her body.

The air conditioner finally kicked on.

Cold air blasted across her flushed face in uneven bursts, rattling softly from the vents.

The AC finally kicked in.

Cold air rushed over her flushed skin, spilling across her face and sliding down her neck in uneven bursts.

“Mhhhhnn…”

The sound slipped out of her before she could stop it, soft and breathy, as her shoulders dropped for just a second in relief.

For a second.

Then the heat underneath it surged back.

Her body reacted instantly.

The air conditioning didn’t slow anything down.

If anything, it highlighted every change happening underneath her clothes.

Miya’s chest shifted again, fuller than before, pressing tighter against the already strained fabric of her blouse. She sucked in a sharp breath, eyes widening as she felt the pressure spike all at once.

“Oh god…”

The next second came too fast.

A sharp pull, a sudden release—

“Ah!~”

Her bra gave out completely, the fabric snapping under the new weight as her chest shifted forward into fuller, heavier curves. The sudden freedom made her jolt in her seat, a startled shake running through her frame.

Her breath caught hard.

Her hands flew instinctively to her chest, trying to steady the new weight as it settled into place, the sensation overwhelming in its suddenness.

Her body responded again immediately after.

A visible jiggle rolled through her new fullness as she moved, even slightly, the motion making her freeze all over again. The change wasn’t subtle anymore. It wasn’t something she could dismiss or hope would pass.

Miya stared down at herself, eyes wide, chest rising and falling quickly as she tried to process it.

“This is happening way too fast… I really shouldn’t have taken the entire vial…”

Her voice came out uneven, barely steady.

The AC kept blowing cold air across her face and shoulders, but her skin stayed hot beneath it, her body still mid-transition, still pushing outward, still rewriting itself in real time.

Her thighs pressed tighter against the seat again.

Her hips shifted slightly as her frame adjusted, the car feeling more cramped by the second.

Miya swallowed hard.

Another pulse rolled through her, slower but heavier, and she let out a small, shaky sound as her posture lifted again into the seatback.

The steering wheel felt lower again.

The roof felt closer again.

And Miya, breathing unevenly, realized the most unsettling part wasn’t the growth itself.

It was that it still hadn’t finished.

“I need… to get to Jenna’s place.” She said shakily as she started to find something to cover herself up.

“They’re so… big… and… soft.” She says grabbing her breasts and playing with them. 

The first contact her fingertips made with her nipples and breasts immediately made her make a face of pure lust.

Her mouth opened and parted, tongue lolling out onto her lower lip as she let out a long moan.

“Awwwwhhn…” Massaging her now luscious D-cup tits, kneading them to feel what it was like to have big breasts for the first time.

She totally distracted herself until she heard other students moving by outside her car, turning bright red as she quickly grabbed a hoodie and threw it over her chest and held it there panting like an animal in heat.

She trembled hard as her ass and thighs began expanding against the driver’s side seat cushion slowly gaining size as she felt her panties suddenly slip between her ass cheeks.

“Ah!~” She let out a cute yelp as she slowly opened her hazy eyes and noticed her perspective rising even higher as her ass growing bigger propelled her upwards.

Her hands continued to grapple with her tits as she desperately held the hoodie against herself to hide her now larger breasts growing bigger under the fabric as they grew and grew into large luscious DD-cups.

She let out another feral moan, moving one hand between her legs only to find her panties tightly bound against her soaking wet pussy, damp and so tight it could make her orgasm within seconds if not careful.

Her eyes rolled back as she humped the cushion, forward and backward, without a second thought as she trembled suddenly cumming in her panties, hearing them rip apart under her ferocious expansion.

“Mmhhhhnnnggh! Awwwwhhhnn!~” She finally came, wetting her torn panties as they clung to her swollen pussy lips suddenly rising another inch taller, then another and another back to back as she grew and grew.

Rising up as her legs stretched out and bended inwards against the pedals under her, avoiding revving the car engine.

She grew passing 5’5… then 5’6… then in moments growing up to 5’7 as she came harder than ever before, finally loosening her grip as she lifted her fingers up to her face seeing her sticky wetness coating them.

Blushing hard she looked down and gasped seeing the cart seat now coated in her wetness and her thick thighs struggling to be contained under her skirt.

“Oh fuck… fuck… fuck… fuck…” She repeated to herself, slowly trembling as she raised the hoodie over her head and felt it get trapped around her waist seeing her arms now sticking out of the sleeves several inches.

“Oh my god… I’m… so much bigger already.” She trembled, moving her hands to a spare set of gym clothes and wiping herself off, her hands first, then down by her crotch as the contact made her entire face crumple up.

“Awwhn… mmmgghh… so… fucking… wet…” She mumbled stuffing the clothes down to soak up some of her passionate juices. 

She quickly reached down and grabbed the stick and put it into reverse, pulling out of the campus and driving down the road, panting heavily as the air conditioning blew cold air onto her sweating face and damp hoodie now tightly bound across her chest.

Miya’s breathing came in uneven bursts as she gripped the steering wheel, the car finally rolling forward out of the parking lot.

The tires hummed against the pavement.

Too normal.

Everything outside looked normal.

That was the worst part.

Inside the car, nothing about her felt normal anymore.

The hoodie was stretched tight around her chest, barely holding anything in place, and every movement sent another wave of pressure through her rapidly changing frame. She kept one hand firmly on the wheel while the other stayed clenched against her body, as if holding herself together by force alone.

“Okay… okay…” she whispered, voice shaky. “Just… drive. Just drive.”

Her posture shifted again.

Subtle.

Then undeniable.

Her seat adjusted under her without warning as her body gained more presence inside it. The belt across her torso felt tighter than before, pressing in a way that made her inhale sharply.

“No, no, no… not again…”

Another pulse rolled through her.

Her shoulders lifted slightly as her frame extended again, the car’s interior seeming to close in around her for a brief moment. The steering wheel felt lower relative to her chest again, like the entire vehicle was slowly shrinking around her instead of the other way around.

She grew another inch to 5’8.

Then another to 5’9.

Her hoodie began to tear under her arms.

Miya swallowed hard.

“I just need to get there…” she muttered.

Her fingers trembled as she reached for the dashboard controls.

The radio clicked on.

Static.

Then music.

Low, distant, almost absurdly cheerful.

Miya let out a shaky breath like she was trying to latch onto it.

“Okay… okay… just focus…”

The sound filled the car, grounding but faint, like it belonged to another world entirely. She turned it up slightly.

A pop song bled through the speakers.

Her grip tightened on the wheel.

Her body shifted again.

A soft, unavoidable adjustment in her posture as she grew slightly more into the seat, hips settling deeper, shoulders lifting a fraction higher. The seat felt tighter than it had seconds ago.

She grew over 5’10 within moments.

She flinched.

“Stop it…” she whispered to herself.

The radio continued playing.

She tried to match her breathing to it.

It didn’t help much.

Another wave rolled through her, slower now, heavier, like her body was still deciding its final shape. Her clothing pulled tighter again, not tearing this time, just… refusing to accommodate the new proportions forming underneath it.

Rising past 5’11, now an entire foot taller than she was only thirty minutes ago.

Miya glanced at the rearview mirror, adjusting it again as she had to push the seat back even further now at her new size.

Her reflection looked different already.

“…Jenna’s house…” she muttered.

Her voice steadied slightly with the thought.

“Almost there.”

The car continued down the road, headlights cutting through the evening light as Miya fought to keep her breathing even, her hands steady, and her rapidly changing body under anything resembling control.

The radio kept playing.

And Miya, flushed, trembling, and still growing in uneven pulses, tightened her grip on the wheel as the first real signs of another surge began to build again.

—

She pulled into Jenna’s neighborhood, still panting slightly as the serum finally began to slowly increase her size instead of larger growth spurts.

Slowly unbuckling the seatbelt and looking down at her now shrunken clothes against her nearly six foot tall frame and the seat being adjusted several times to fit, she felt cramped.

“Oh my fucking god… I’m… so tall… and busty.” She said, grabbing her chest and suddenly letting out another moan as she nearly squirts from her pussy again.

“God… I can’t touch them without… wanting to cum all over again.” She quickly caught her breath grabbing her phone and texting.

Miya:
“I’m here.”

Some moments later she got a text back.

Jenna:

“Okay, I’m coming down.”

Miya slowly exhaled and stepped out of her car feeling dizzy for a moment as she stretched her hoodie tore open down the sides and left her topless.

“Fuck!” She yelled, grabbing onto her tits as she looked down and felt her thighs wiggle and tear whatever remained of her panties right off onto the pavement.

“Oh no… no… no no…” She looked down and her ass and soaking wet red pussy were on full display. 

Her skirt was so tight around her waist it barely fit over her new larger ass and hips, treading near her stomach instead, way above her thighs.

Her blouse hung loosely off her shoulders with none of the buttons on it anymore.

She looked over at the house, and quickly bounced over to the front door, knocking frantically as she heard thumping from behind the door.

The door opened revealing Jenna now standing at a towering height, her head brushing against the top of the doorframe as she looked down, ducking slightly.

“Miya?! Oh. My. God. What the fuck happened to you?” Jenna could hardly handle looking down to see the once tiny Miya now a tall, busty, proto-amazon sized asian girl with a body like an athlete on full display.

“I… sort of… took the serum…” She said blushing hard, still having to look all the way up at her in the doorway, taking up all the space.

“Come inside! Oh my god.” Jenna quickly had her come inside and shut the door.” Grabbing her brother’s jacket to cover her bare tits.

“T-thanks… I’m sorry… I don’t know what I was thinking.” Miya said blushing hard before Jenna’s massive body hugged her warmly.

“Hey! It’s okay… you look… amazing. How much did you take?” Jenna asks as Miya’s face blushes even harder.

“I took… an entire vial–” Miya suddenly gets cut off by Jenna’s loud gasp.

“What?! Oh fuck… Miya… what the hell?” Jenna responds with a sharp tone.

“I… I don’t know what came over me… I just… wanted to be big… like you and… the others…” Miya blushes even harder now as she comes to the realization of her mistake.

“I can’t believe it… I didn’t think you would ever do it.” Jenna chuckles, slightly crossing her arms under her enormous breasts.

“Me neither…” Miya says acting shy.

“Come on! Let’s measure you and we can both find something that fits.

“Oh… okay…” Miya follows her upstairs adjusting to her new height, struggling to walk with all the new pounds of curves.

They quickly bounded up the stairs avoiding her brother and finding themselves something to cover up their enormous new assets.

Neither of them knew just how much their lives would change in the next coming days.

Only time would tell.
