Her Curves

Chapter 8 - The Upper Class

Written by: GrowthGooru

The night was loud.

All the women in the house were making noise and Jake could hardly sleep between the creaking of beds and soft moans he could hear echoing down the hallway outside of his room.

After suddenly taking the serum to everyone’s surprise, Janice wasn’t even done growing from her dose. Having finished the rest of the vial, she had ingested a little less than what Jenna had spaced out over days of time, but all at once, this changed her reaction to the growth enzymes which now flooded her system. Her mature body was in overdrive, pumping out growth hormones from her pituitary gland over and over, increasing in mass and size every so often with a quiet shudder.

Her bed creaked as she stretched across it overtaking the length of her queen-sized mattress. Her legs reaching down longer as the night stretched on, so did she, gaining size and growing bigger and bigger.

Her already huge and wide ass grew even larger, her naked cheeks expanding against her bedsheets slowly pushing them off the bed spreading further apart as her wet pussy glistened under the soft moonlight shining through the blinds of her window.

“Mmmmhhhh…” 

She moaned as her body trembled with a shuddering exhale growing another inch larger to 6’10" as her ankles passed the end of the bed growing longer legs. Her thighs expanded like marshmallows in a microwave, gaining size and plumping up bigger as her ass and hips grew alongside it.

Her rumbling groans only grew louder as the bed creaked adjusting to her growing body, gaining size every so often still increasing in weight and curvature. Her breasts grew even larger than the size of soft jiggly basketballs, pressing against her bedsheet and pulling it down and over her waist as it slowly slid off her huge curves.

Massive gumball sized nipples swelled and ached for her touch as she lazily turned onto her back making her bountiful breasts jiggle and settle after a few moments, spreading across her chest like two mammary mountains. She let out another long exasperated sigh in her sleep moving her arms down her curves absent mindedly, jiggling against her fingertips.

“Awwwhhnn…” 

She moaned louder, moving her hands down past her giant hips and toward her vagina, her cherry-red clit aching for attention, dripping wetness onto her sheets slowly starting to slide off the mattress barely able to contain her growing body.

Her body only grew another inch in size growing close to the next foot mark as she grew to 6’11" still groaning in her sleep as it seemed to be a never ending growth spurt. Her curves expand against the bedside, gaining size and weight, growing thick and extremely voluptuous. Her naked form growing into a fertility goddess in shape and size, as her already wide hips grew enormous in depth, her tremendous thighs could now easily crush a man’s head between them.

The bed frame began to loudly respond as she crossed seven feet tall.

Her body had already stretched beyond the mattress, her legs extending farther and farther until her feet reached the floor. One foot pressed against the carpet, slowly pushing into it as the fibers flattened beneath her heel. The other followed, nudging the loose carpet toward the wall.

“Mmmmm… yeahhhh…”

She spoke to herself in her sleep, completely unaware of how much space she was taking up.

Then another inch came as she rose to 7’1".

Her legs lengthened again, her knees sliding closer to the edge of the mattress while her thighs thickened with the growth. The sheets tightened around them, bunching beneath her as there was less and less mattress left to support her.

The frame groaned as she barely reacted.

Another wave rolled through her making her grow past 7’2" swelling out of control.

Her hips broadened next, pushing farther over the sides of the mattress. The sheets were dragged tight beneath her as her growing body spilled outward. The wooden frame flexed under the shifting weight.

Creaaaak.

Her upper body followed, her shoulders widened, as her torso stretched longer.

Two massive watermelons now displayed an equal size measurement for the now two enormous breasts on her chest, swelling bigger into massive M-cups and taking up more of her space as they jiggled free from the blanket covering atop of her. Her chest expanded with the rest of her frame, pushing it upward until it could barely cover her anymore.

“Mmm…”

A sleepy little smile crossed her face as she began to grow even bigger, passing 7’3".

Her feet pushed firmly against the wall now.

The pressure made the wall give a tiny thump.

Her legs continued extending, forcing her knees and thighs farther beyond the mattress. Her calves slid off the edge completely, leaving her lower legs hanging toward the floor.

The bedposts rattled.

The screws holding the frame together began to loosen.

Then another inch rolled through her chest and all the way down to her ass, then her thighs and feet growing to 7 '4".

She began to outgrow even Miya’s size and breast size, passing her by as she continued growing and expanding bigger and bigger.

Janice had officially grown beyond her size, growing into a busty amazon goddess.

Her hips pushed even farther over the mattress, leaving only part of her lower back supported. Her shoulders widened until the mattress looked almost ridiculously narrow beneath her.

The blanket slid down her expanding body.

Her arms stretched longer, one hanging over the edge of the bed while her fingertips nearly brushed the floor.

She let out another satisfied groan as her entire body rose another inch all at once to 7’5" tall.

“Mmmm… bigger…”

The frame answered with a sharp crack.

CRACK.

Janice shifted in her sleep and that was all it took.

Her legs extended another inch.

Her feet pressed harder against the wall, toes curling slightly as the pressure increased. Her thighs pushed completely beyond the mattress now, leaving the bed supporting little more than her torso.

Her hips widened again growing thick thighs to match her tremendous curves.

The mattress compressed beneath her.

Her shoulders expanded.

The headboard creaked against the wall.

Her growing chest pushed the blanket forward, while her entire torso continued becoming broader and heavier. The poor mattress was now visibly bowed beneath her.

“Mmmmmmhhhhmmmm…” 

She mumbled as her entire body shuddered slowly growing even bigger to over seven and a half feet tall.

The wooden posts shook violently.

The screws began popping loose one by one.

Click.

Click.

CRACK.

Janice didn't even wake up.

Her enormous body had simply become too large for the bed.

Her thundering thighs matched her long and strong legs stretched beyond the mattress.

Her huge round hips spilled over both sides.

Her wide shoulders pressed against the headboard and her feet remained planted against the wall.

There was practically nowhere left for her to grow.

Her frame surged larger again, muscles and curves expanding together as the serum continued forcing her mature body through a second impossible growth cycle.

The mattress gave a final, exhausted squeal.

Then the frame split.

CRACK!

SNAP!

The wooden posts collapsed inward.

The mattress dropped several inches before hitting the floor, throwing Janice's enormous body downward with it.

THUMP!

The impact made the mattress bounce beneath her.

Janice's entire body shifted with it jiggling for a few long moments.

She merely rolled slightly onto her side, her two massive tits squished together on her chest, pulled part of the blanket back over herself, barely covering up to her lower breast, and sighed contentedly.

The room fell silent and for several seconds, nothing moved.

Then the broken bed frame gave one final little creak beneath her.

Janice smiled in her sleep.

—

Down and across the hall, the two girls slept together in Jenna’s room, making just as much noise if not more, cuddling one another on the floor as the bed couldn’t contain them both at the same time. Bedsheets and covers, pillows, and blankets were strewn all over the floor around them, barely covering them as they laid together in a cute snuggle.

Miya’s enormous breasts were pressed against Jenna’s back, slowly moaning in her sleep against her, hugging her gently bound against her huge chest. Jenna nestled up against her, feeling her warm nipples brushing against her bare back, feeling the weight of her massive mammaries as she moaned softly beneath her burgeoning body.

“Mmmhhhhnnn…”

Jenna let out a long sigh that turned into a moan, feeling her body rumble ever so slightly as she grew an inch larger at once, gaining more weight as she grew to 6’8", with a cute shudder beneath Miya’s wide arms.

“Awwwhhh…”

Then another as she let out another cute moan, growing to 6’9" to match Janice’s size only a few hours ago, now far surpassed by Miya. Jenna shuddered as her own body grew larger to match, her frame becoming fuller and heavier beneath the blankets.

Without waiting a beat, Miya’s body responded in more growth. Her body trembled as she let out a rumbling giggle in her sleep as she grew past 7’5", gaining inches of thickness around her thighs, hips, ass, and in her huge tits as well.

“Mhhhhhnnn…”

Miya rumbled, growing thicker and larger by the second, dwarfing the nearby nightstand and making it fall over. Then she began pushing the bed aside with just her hips widening and growing bigger and heavier, the wooden frame scraping across the floor as her expanding body continued taking over the room.

The Asian bombshell grew even bigger and wider, expanding and rising past 7’6" as her body rumbled against Jenna’s resting body, which was starting to become quite small compared to her shuddering size. Her wide hips grew even more thick as her thighs and ass grew to match, gaining inch after inch of depth as her body reacted to the full vial of serum she drank all to herself.

Her body was starting to go into overdrive as her pituitary gland had grown massive and swelled to nearly double its size. Another powerful tremor traveled through her sleeping body, making Jenna shift softly within her embrace.

Miya blushed hard in her sleep, lazily cupping her breasts as they grew even more expansive, growing up against her palms, then outwards spilling around her fingertips as they sank into their immense softness. Her sleepy expression tightened for a moment as another shudder passed through her, followed by a deep, vibrating moan.

Miya’s body was relentless. Growing continually, expanding under Jenna as she started to lift slowly forward as she grew even bigger. She rose past 7’7" trembling, her enormous body stretching farther across the floor as her feet slowly approached the wall where they lay sleeping together.

“Biiiiiggggger…”

She mumbled to herself as she grew even bigger, her long legs extending until her feet finally touched the end of the wall. Their blankets slowly slid off her enormous body as her head rose up past her pillow and onto the bedside, pushing it further away as she grew out of control.

Another wave passed through her.

Miya shuddered and stretched to 7’8", her enormous frame becoming heavier and broader around Jenna. Her hips pressed against the abandoned bed, forcing it farther aside, while her long arms tightened instinctively around Jenna in her sleep.

Neither girl woke.

Miya simply continued growing.

At 7’9", her legs stretched farther along the floor, her feet pressing firmly against the wall as her shoulders widened around Jenna. The blankets had almost completely fallen away now, unable to keep up with her expanding body.

“Mmmhhh…”

She sighed sleepily.

Another surge.

7’10".

Her body trembled again, her hips widening and her thighs thickening as the floor creaked beneath her. The bed scraped another few inches away, and the fallen nightstand lay forgotten beside them.

Jenna remained peacefully asleep in Miya’s arms.

Then the final wave came.

Miya shuddered from head to toe as she reached 7’11". Her feet pressed against the wall, her head rose beyond the pillow, and her enormous body settled heavily across nearly the entire bedroom floor.

The room was now a complete mess of overturned furniture, pillows, sheets, and blankets.

Miya didn't seem to notice.

She only tightened her arms around Jenna, pulled her closer against her immense warmth, and let out one final satisfied moan before sinking into a deeper sleep.

“Mmmm…”

For the moment, at least, the growth had finally stopped.

—

Down and across the hall, the two girls were still asleep together in Jenna’s room, tangled among the sheets, covers, pillows, and blankets that had been scattered across the floor during the night. The bed had been shoved aside hours ago, leaving the two enormous women curled together on the carpet in a warm, cramped snuggle.

Miya, now a towering 7'11", had practically swallowed the room with her size. Jenna, at 6'9", was still huge herself, but beside Miya she looked small now. She was over a foot taller than Jenna now, a full fourteen inches of difference was impossible to miss. Even curled together on the floor, Miya's longer frame stretched well beyond Jenna's, her knees and feet reaching farther toward the wall while her shoulders and upper body rose noticeably higher.

Neither woman noticed.

They slept peacefully until a sudden sound rang out.

THUMP.

It shook the room.

Jenna's eyes fluttered.

THUMP.

Her eyebrows twitched.

“Mmmm…”

She slowly opened her eyes, still groggy and confused.

For a moment, she couldn't figure out why everything seemed so dark.

Then she realized she wasn't looking at the ceiling.

Her head was nestled directly against Miya's enormous chest, safely cradled between the huge curves of the sleeping giantess above her. Miya had unconsciously curled herself around Jenna during the night, one massive arm resting around her while the other lay loosely across the blankets.

Jenna blinked.

“...Miya?”

THUMP. 

The sound surprised them both as it came from somewhere near the foot of the room.

Jenna shifted slightly and finally looked upward.

And upward.

Miya's face was far above her.

Even sitting up, Jenna's 6'9" frame would only bring her head roughly around Miya's upper chest. Standing beside her, the difference would be even more obvious now. Jenna's head would reach only around Miya's upper chest and shoulder area, while Miya's chin would sit roughly a foot above the top of Jenna's head. Her shoulders would stand several inches above Jenna's, making the fourteen-inch difference immediately obvious.

But lying together like this made Miya seem even larger.

Jenna was practically tucked inside the curve of her body.

Miya stirred.

Her enormous frame shifted beneath Jenna, and the movement sent another soft tremor through the blankets.

“Mmmmm…”

Her eyes remained closed.

Jenna stared at her.

“Oh god… you grew again.”

Miya gave no answer.

Instead, she stretched in her sleep.

Her long legs pushed farther against the wall and her shoulders rolled backward.

Her arms tightened instinctively around Jenna as she suddenly felt just how much larger Miya had become.

At 7'11", Miya's body seemed to occupy almost the entire floor. Her head was high enough that even sitting upright she would tower over Jenna, while her legs extended so far that her feet were pressed against the opposite wall.

Jenna slowly pushed herself upright.

That only made the comparison more ridiculous.

She was already 6'9".

Already tall enough to tower over almost anyone.

Yet beside Miya, she looked noticeably smaller.

Jenna's head sat below Miya's chin.

Her eyes were around Miya's upper-chest level, her two now watermelon sized mammaries jiggled slightly as she moved slightly in her sleep.

THUMP.

Both women's eyes opened this time.

Miya blinked sleepily.

“...What was that?”

Jenna looked toward the door.

“I have no idea.”

Miya tried to sit up.

The movement immediately caused the floor to creak.

Her head rose higher as her wide and tall shoulders lifted above Jenna.

Her enormous legs stretched out beneath the blankets.

And as she finally sat upright, Jenna had to tilt her head back just to look at her face.

Miya stared down at her and then around the room.

Her eyes landed on the fallen nightstand, then the displaced bed against the other wall.

Blankets everywhere, strewn over the floor, and a crushed up pillow that had somehow ended up against the wall.

She slowly smiled.

“Hehe… whoops.”

Jenna narrowed her eyes.

“What?”

Miya looked down at herself.

“Oh god… the formula must still be working in my system. I grew bigger again.”

Jenna turned her head slightly upward as she saw the bottom of Miya’s face above her.

“Yeah. You're… huge.”

Miya's sleepy smile widened.

“Really?”

Jenna sighed.

“Yeah really.”

Miya looked almost delighted by the answer.

Then another loud sound.

THUMP. 

It came from somewhere down the hall.

Both women froze.

Jenna looked toward the bedroom door.

Miya looked down at her enormous body.

Neither of them said anything.

Then Jenna slowly smiled.

“Sounds like we're not the only ones who had a growth spurt.”

Miya's eyes widened.

“Your Mom?”

Jenna nodded and let out a scoff.

“Ugh. Probably...”

The two giant women looked toward the hallway.

And suddenly the ruined bedroom seemed like the least of their problems.

—

Down the hallway in Janice’s bedroom, the walls shook.

THUMP.

“Ugh! Come on!”

Janice tried not to yell as she backed toward the doorway, only to feel her enormous hips press firmly against the frame.

“I should’ve never had any of that stupid serum.”

She grumbled under her breath, twisting sideways and carefully squeezing herself through.

Her tremendous hips rubbed against both sides of the doorway before she finally managed to slide inside. The moment she cleared the frame, her whole body jiggled from the effort, her massive curves settling as she caught her breath.

Janice looked around.

Everything seemed smaller.

She could easily see over the shelves now. The bathroom curtain bar looked ridiculously low beneath her. Even the top of the furniture that had once been above her eye level was now practically within reach.

“Seriously?”

She shook her head and slowly turned toward the full-length mirror.

Then she stopped.

“Oh… wow.”

Janice stared.

The mirror had always seemed plenty large before.

Now it looked tiny.

At 7'6", Janice stood a full eighteen inches taller than the six-foot mirror. Standing directly in front of it, she couldn't even see the top of her head. The reflection cut her off around the upper shoulders, leaving her face and enormous upper body filling practically the entire mirror.

Her cheeks immediately turned bright red.

“That's... me?”

She leaned closer, then immediately had to straighten again when her massive chest nearly crowded the mirror.

Her breasts were enormous now, two heavy, soft curves that dominated the reflection. They jiggled slightly as she moved, looking almost absurdly oversized against the furniture surrounding her. Her flushed cheeks grew even redder as she realized just how much of her body the mirror could no longer contain.

She glanced down.

Then back to the mirror.

Her eyes widened.

Even from this angle, her enlarged chest filled much of the reflection, with her enlarged nipples visibly red and puffy against the otherwise smooth curves of her breasts.

“Oh my god…”

The woman staring back at her barely looked like the Janice she remembered.

Her shoulders were broad. Her waist had thickened. Her hips looked enormous, stretching far beyond the proportions she'd been used to seeing in the mirror. Her whole body had become an exaggerated, towering hourglass shape.

She slowly turned sideways.

The reflection barely contained her.

“I'm… so much bigger.”

The words came out as a whisper.

Janice placed one hand against her stomach and looked at herself over again. At this height, even the familiar bedroom seemed miniature. The mirror itself was almost comically inadequate for her new size.

She took another step backward.

Her reflection changed.

For the first time, she could see more of her body at once.

Her eyes widened again.

“Oh… my goodness gracious.”

She backed up another step.

Now her hips came into view.

She stared at herself for several seconds before covering her face with both hands.

“I look like some kind of fertility goddess.”

She lowered her hands and moved her fingertips over her lips feeling them and shuddering.

The thought made her cheeks burn even hotter.

Then she looked down at her enormous body again, slowly realizing just how much she'd changed.

“So… sexy.”

She let out a breathy moan as she turned and stuck out her huge ass looking back at it.

“Oh wow… my ass grew huge.”

Her pussy lips swollen and wet were oozing down her thighs as she spread her legs a jolt of pleasure ran throughout her body making her thighs tremble.

“God… I’m… so wet.”

Her fingers motioned down between her tremendously thick thighs, her two longest fingers moving down to find her clit.

It was large and throbbing for her as she placed her index finger onto it she immediately yelped, making a loud sound.

THUMP.

The mirror rattled. 

“Oh… gosh…” 

Janice shook as she continued pleasuring herself, shaking with lust, as she couldn’t stop herself. 

As Janice's fingers danced across her engorged clit, sparks of pleasure shot through her colossal frame. The mirror shook violently as her massive body quivered, her breasts heaving with each ragged breath. 

THUMP. 

She cried out again, the sound echoing off the walls as her finger rubbed faster. "Oh, yes!" Her moans grew louder, a deep rumble that vibrated through her huge thighs. Suddenly, she froze, her back arching as a tidal wave of ecstasy crashed over her. 

"AHHH!" 

Janice screamed, her orgasm tearing through her like a storm. She convulsed, her pussy clenching around nothing as she spilled juices down her trembling legs. Panting, Janice slowly opened her eyes, gazing down at her still-quaking body. 

"Wow..." 

She breathed, a satisfied smile spreading across her face. 

"Being this size is incredible." 

With a languid stretch, Janice raised her massive hand to her lips, savoring the scent of her own arousal. Her thick fingers slipped into her mouth, and she sucked greedily, tasting the tang of her climax on her skin. 

"Mmmm..." 

A low hum vibrated through her body as she licked and nibbled her fingers clean. She sucked harder, her cheeks hollowing as she drew every last drop of her essence from her fingers. 

"So good," 

She purred, releasing her fingers with a pop. 

THUMP. 

The floor shook beneath her, sending ripples through the tiles. Janice giggled, the sound like thunder in her own ears. Rising to her full height, Janice strode towards the shower, each step a resounding crash of her massive weight against the floor. The shower bar rattled ominously as she ducked through it, her colossal frame barely fitting. 

"Time to clean up," 

She murmured, twisting the taps. A roar of water greeted her, steaming up the mirrors. She stepped under the torrent, letting the warmth soak into her pores, her nipples puckering under the spray. 

"Mmmm... this feels amazing." 

Her hands slid over her gargantuan form, soaping her breasts and belly. 

“Gosh. I’m so much bigger. Everything is so small now.”

She giggles as her enormous watermelon sized breasts jiggle under her hands as she cups them and smiles massaging in soapy water, lathering them up between her fingertips.

“Goodness. What is Jenna going to say… I’m probably way bigger than her now.”

She bites her lip letting out a sultry giggle as she gathers her enormous breasts together and watches the hot water rinse them down as her nipples stand hard against the stream. 

“So much bigger.”

She coos rubbing her nipples and squeezing her large breasts together happily humming away as the shower heat billows into the bathroom fogging up the mirror.

—

Jenna carefully ducked her head under the doorframe not moving much as she smiled, realizing she’s far grown past the height of it now.

“Whoa. I’m definitely bigger too.”

Miya on the other hand had to lower her body fairly low and then squeeze her hips through the doorway.

THUMP… THUMP. THUMP.

Her massive legs and feet collided with the floor making sounds with each adjustment.

“Ugh… almost got stuck.”

She slowly stands up and her now long jet black hair brushes the top of the eight foot high ceiling.

“Oh wow…”

Miya swallowed hard, noticing her eyes were level with the ceiling lamps, having to move around them, but then colliding softly with the walls. Her enormous ass and hips squished against the tight space as she followed alongside Jenna looking toward the end of the hallway to her felt like a couple steps now.

“This is… fascinating.”

She felt an arousal flood through her. She was so much bigger now. Her eyes tilted down to see Jenna’s head under her shoulders, barely reaching her humongous breasts blocking most of the view down to her, unless she leaned over, feeling them jiggle up and out of her straining summer dress.

“You’re… huge.”

Jenna swallowed hard, seeing her giant breasts on full display in front of her as she heard her giggle bending down to see her face of shock and awe written all over it. Her eyes slowly travelled up the expanse of her immense cleavage, a valley of soft white bounciness. Moving up past her neck and up her chin to her large luscious lips, then farther to her two large jewels of darkness. Her eyes peered down at her as she grinned and reached out grabbing her and hoisting her into her breasts.

“Aww! You’re so cute now! Come here.” 

Miya smothered her, surrounding her head with her tits and pushing them in her face as she grinned loving the strength of her new five-hundred foot pound body. 

“Miya–mmph!” 

Jenna felt powerless as her massive arms and breasts wrapped her up and squeezed her tightly, lifting her off the carpet floor. Her enormous nipples slid across her face as she felt their swollen thickness. 

“You’re perfect right down there. Between my big fat titties.”

Miya smiled devilishly as this power and strength over her was intoxicating. She then suddenly felt herself going overboard blushing hard.

“Oh! I’m sorry, are you suffocating?”

She quickly pulled her back hearing her gasp and started panting.

“Fuck… only a little.”

Jenna was so turned on. Miya had never been that forceful with her, she smirked and looked back up and her cheeks turned bright red. 

“Mmm… come here.”

Miya couldn’t help herself, she leaned down to her, so that their faces were level as she puckered up her two large fluffy lips and began kissing her with a soft yet gentle wetness. 

“Mmmph… Miya…”

Jenna’s eyes widened as her larger lips pressed against her own and then as her tongue danced around hers she slowly lowered her eyes and closed them moaning softly muffled against her vibrating sound echoing down her throat. The two of them moaned louder one after the other until suddenly the other hallway door opened.

“Uhh… Jenna… oh my god.”

Jake’s body froze looking up at them and Jenna’s lips snapped off Miya’s as she straightened herself up in the background watching Jenna move to him blocking his vantage point to her.

“Good morning, little brother.” 

Jenna looked down at him smirking as she was now nearly a foot taller than him, seeing his shoulders barely reaching the top of his head as her breasts were at his eye level now.

“Oh no… you grew again. When will it stop?” 

He asks as he swallows hard watching her step forward and nearly touch his face against his breasts, as she doesn’t even have to bend over at all. 

“Yeah. A little bit bigger. Everyday. I might grow some more soon, who knows.”

“Quit bullying him!”

Miya shouted towering over them both as she leaned down her breasts pushed Jenna aside literally mashing her even more massive breasts against her face from behind her.

“Miya!”

Jenna shouted back as she easily moved her aside with her towering size and then looked down at him and turned bright red blushing hard.

“Oh god. You’re… so… small.”

Miya couldn’t help herself, she blushed moving her hand between her tremendous thighs pressing against her wet pussy. 

“You… grew a lot… you’re so much… bigger.”

Jake couldn’t help his reaction either as his cock got hard pitching a tent looking up at her listening to her panting looking down at him with a lustful stare. She smirked and rose up to her full height and stepped forward, placing her hand down on top of his head and measuring it under her enormous watermelon sized breasts.

“You don’t even reach my tits anymore.”

He could hear her breathing getting harder and faster as she moaned softly looking down at him with intensity, with half-lidded eyes and more horny for him than ever before. He looked up staring at her enormous breasts and her big swollen nipples above his head watching them move back and forth between her moans growing louder.

“Stop staring at her! What the fuck! Pervert!”

Jenna looked down and interrupted them as she pushed him into his room and closed the door.

“Jenna! Wait! Miya!” He went to open the door suddenly when they heard another sound from down at the end of the hallway.

“Good morning girls!”

Janice appeared and yawned before leaning down and ducking under the doorway to her bedroom.

“Goodness. Everything is so much smaller out here too.”

She said with a smirk looking down at Jenna and up at Miya as she got closer to them.

“Miya. Wow… and Jen! You look so cute now, aww, honey!”

Janice quickly tried to brush off Miya, still towering over her even after her huge growth spurt with a hint of jealousy in her voice.

“Mom?! How the hell did you grow so much?”

Jenna’s eyes blew wide open in shock looking up at her mother now towering over her by nine inches.

“I don’t know, sweetie. Didn’t you make this serum Miya? I only drank a little. I promise.”

Janice giggles as her chest jiggles looking down and quickly interrupts Miya as she continues.

“Where’s my boy? Jake. Come on, it’s time for breakfast.”

Jake’s eyes widened behind the doorway as he could hear them in front of his bedroom door.

“Coming, mom!”

He opens the door as he steps out in the middle of them all now towering over him and then she gasps audibly.

“Jake! Oh my gosh, you are so precious. Look at you down there.”

She stepped forward and looked down, hugging his head against her breasts leaning down to accommodate him.

“Mmph! Mom!”

He could barely see his shoulders were level with her wide hips as she smothered him between her cleavage suddenly feeling her jiggly softness against each of his cheeks.

“You’re totally smothering him…”

Jenna blushed trying to act unphased as she heard him struggle turning her on a little.

“Please don’t hurt him.”

Miya pleaded as she fought back the urge to touch herself. She grabbed her thighs bending over slightly as she let out a soft moan, sinking her fingers in and trembling.

“Oh! Of course not, honey.”

She then leaned back and let him breath, hearing him gasp for air and buckle over.

“Come help momma make breakfast, everyone.”

“Y-yes, mom.” 

Jake replied instantly and nodded going back into his room to get dress.

“You two ladies. And take a shower.”

Janice put her nose up and moved downstairs as they both blushed embarrassed.

“Ugh. How did she get so big?”

Jenna looked so flushed and embarrassed she looked up at Miya with a worried glare.

“Hmm… I don’t know. I’m thinking of hormone imbalances. I mean look at me. I’m… enormous.”

Miya gestures to her head nearly touching the ceiling an inch away.

“Yeah, but you took a whole vial at once. I really hope you stop growing soon.”

Jenna replied looking back with even more worry.

“Me too. I’m already way too big.”

Miya responded looking back down at her and continuing her thought.

“It’s okay. Go take yours first, I’ll take one after.”

“Okay…”

Jenna rolled her eyes and grabbed a towel and stepped into the bathroom ducking her head slightly and turning on the hot water.

—

Then Miya quickly stepped inside Jake’s room, closing the door as he yelped and turned around.

“Uhh… what are you doing here?”

She stepped closer as her feet thumped against the carpet avoiding hitting the ceiling lamp.

“Is that how you want to greet me?”

Her large lips curved into a wicked smile looking down at his shoulders down past her hips, imagining how easy it would be to just sit on his face.

“No! I mean… I didn’t mean it like that.”

He quivered with fear as she got closer and leaned down close to his lips.

“Then what’s your… problem…” 

She grinned and leaned back and giggled massaging her enormous breasts and letting out a soft moan moving her other hand down between her legs and rubbing her pussy through her panties.

“I'm so horny.”

She interrupted herself letting out a sultry giggle looking down at him barely able to see past her own breasts without leaning over down to his level.

“Sorry you’re so fucking small compared to me now.”

She let out a strained teasing laugh massaging herself more.

“I’m not small! You’re huge!”

He nearly shouted as she clasped her hand over his mouth to quiet him down.

“Shh… I know.”

Miya pushed him onto the bed and held his mouth shut pushing him onto the mattress as she pulled off his pants with her other hand.

“And it turns me on… like crazy.”

He suddenly tried to stop her as she began leaning down to lick and suck on his cock.

“Fuck–Miya. We have to go downstairs soon.”

Jake could hardly resist as his hard cock throbbed in her mouth, sucking and licking his shaft up to the head of his cock.

“Jen takes long showers… but I’ll make you cum fast, I promise.”

Miya’s lips take longer laps across his cock as he’s as hard as he can get before she lifted her tremendous thighs and then positioned herself carefully over top of him.

“Awhn… yeah.” 

Her thighs landed with a soft thump, moving his cock deep inside her pussy.

Miya's enormous thighs pressed against him, trapping him beneath her sheer size as the mattress groaned under her weight.

She shifted carefully, and Jake felt the entire bed sink beneath them as his cock sunk inside her pussy.

"Fuck, Miya..."

She laughed softly, looking down at him.

"What's wrong?"

"You're crushing me."

Miya glanced down at her massive body and then back at him with a smug little grin.

"Sorry. I keep forgetting how much bigger I've gotten."

At seven feet eleven inches and well over five hundred pounds, almost everything about her had become overwhelming. Her enormous thighs, broad hips, and massive M-cup breasts made Jake look ridiculously small beneath her as she forced his cock deep inside of her.

She leaned forward, her long black hair falling around them.

"You really are tiny compared to me now."

His body trembled as his hard cock went deeper inside of her, crushing him harder against the mattress.

“You’re… enormous.”

Jake panted and grunted as her ass and thighs weighed him down further, struggling to even pump his hips back and forth as she kept bouncing jiggling all at once and grinding down on his cock, going in and out, in and out, fucking her giant body atop of him.

“You’re just now noticing that? Mmmmm… fuck… you feel so good.”

Her ass jiggled as her thighs came down with a wet slap rhythmically with each motion against him, making his entire body bounce and flex against her massive body.

“I’m… gonna cum.”

His cock throbbed and ached as he was about to erupt, holding back as her vagina came down sliding his cock into her over and over.

“Awwwhn. Yeah. Cum inside me.”

Miya cooed, moving her pace faster and faster as she started to rumble and moan, reaching a climax while her entire body trembled and began to rumble with growth.

“AHHN!” 

She shouted, then quickly covered her mouth, blushing hard as her entire body grew larger. Her body surged with size growing past eight feet tall in mere moments. She only grew even bigger as her pituitary gland spiked her blood with more growth hormones causing her to grow another inch taller to 8’1", then another growing to a towering 8’2" tall.

“Miya! Nngh!” 

Jake tried to keep himself quiet as his cock ached and throbbed and finally erupted. His hot wet cum flooded her vagina, feeling it spill into her as he shook for a few moments, grunting and trying to compose himself. 

“God… that was… amazing.”

Miya moaned as she slumped over on top of him, his cock slipping out as she laid down beside him smothering him with her breasts.

“Yeah it was.”

Jake looked up at her as she closed her eyes for a moment, stretching her arms overhead as she hit the wall then up by the ceiling.

“Oh no… I grew again.”

Miya blushed hard looking down, noticing his head was way down by her breasts while lying down together.

“No way. Didn’t you just grow overnight?”

Jake asked as she got up forcing him to get up off of her.

“Stand up.” 

Miya commanded blushing embarrassed as she straightened her body out her head softly bumping against the ceiling.

“I knew it. Fuck.”

She ducked slightly while keeping her body straight as he stepped forward and had to look way up to see her face now, as she lowered her head and her eyes widened.

“I’m over eight feet tall now. Look, my head hits the ceiling!”

Miya tried to keep herself calm, but she was freaking out about everything now.

“It’s okay. You look… incredible–”

Jake looked up and suddenly stopped mid sentence.

“Oh shut up! How am I going to work in the lab today?”

Miya suddenly cut him off looking flustered and down at her giant breasts bigger than ever, nearly the size of beachballs.

“I… I don’t–”

Jake tried again, but she continued on.

“Yeah! You don’t know… do you? Mmmmhhhnn… fuck… not again.”

Miya’s hormones continued raging, making her grow even hotter as her body grew outwards another inch taller to 8’3".

“Oh shit. You’re growing again!”

Jake shouted up at her as she grabbed his head and stuffed it between her thighs.

“I said shut up. Oh my god. Fuck…”

Miya’s entire body rumbled and grew hot and heavy as she grew exponentially larger, another inch bigger to 8’4".

“Mmmmm… I should’ve never drank an entire vial. The effects are compounding–nngh! Awhn!”

She suddenly came again as her eyes rolled back and shook, feeling like his cock was still penetrating deep inside of her, yet all she could feel was his head buried between her legs as she shook and grew another inch larger to 8’5".

“Ohhh… god… okay… that’s enough. Little man.” 

She finally let him go as he left dazed and confused, smelling like pussy and sex.

“Fuck… jesus.”

Jake said as he looked up, seeing her bend over against the ceiling now absolutely dwarfing him in size.

“I grew… so much.”

Miya said blushing and looking down at his head and measuring it against the start of her waist under her belly button.

“What are we going to do?” 

Jake was blushing harder looking up at her as she reached down and grabbed his chin and lifted it even further up.

“Get breakfast. You need to clean up first. Shower’s mine next though.”

She grinned as they both heard a knock on his door.

“Hey, little brother, open up! Where’s Miya? It’s her turn to shower.”

Miya turned bright red in both cheeks and froze for a moment looking down at him frantically.

“She’s coming!”

She then leaned all the way down giving him a big wet kiss with tongue dancing around his smaller mouth. Then she grinned and straightened up ducking down trying not to hit the ceiling as she moved toward the door.

THUMP… THUMP… THUMP…

Every step she took caused the room to shake, she was over five-hundred and seventy five pounds, each of her thighs were larger than his entire upper body. She strode over and opened the door leaning down under it and smiling down at Jenna.

“Oh my GOD!”

Jenna shouted looking up at Miya’s towering head looking down at her grinning.

“What’s up? Shower time?”

“Oh god! You grew again!”

Jenna said, seeing her giant body push forward and grunt against the doorframe.

“Nngh… can you… give me some room, please?”

Miya’s ass got stuck wiggling against the doorframe as her hips bulged against the sides of the wooden panels.

“Oh no… you’re grown too big.”

“I’m fine! Just like… go downstairs…nngh… ah!”

Her ass finally cracked against the walls before she pushed off releasing her thickness and landing against the other wall with another loud thump causing the wall to crack.

“Fuck…”

Miya looked down, seeing her ass imprint against the wall behind her as she adjusted again, moving to the bathroom crawling against the ceiling, ducking under the ceiling lamps.

“Miya!”

Jenna shouted back at her, seeing her giant ass taking up most of the hallway swaying from side to side as she bent down. She could see her wet pussy dripping down her thighs as she blushed hard.

“I’m sorry…”

Miya said sheepishly moving to the bathroom as she began to realize she wouldn’t be able to fit in the shower stall. Her hips would get wedged in the door again, and even worse in the shower itself.

“Uhh… do you have a bigger shower downstairs?”

“No! Does this look like a hotel?”

Jenna looked annoyed at this point, she was starting to regret convincing her to take some serum herself, knowing she might go overboard.

“I’m s-sorry… I don’t think I can fit in there…”

Miya couldn’t help but blush even harder as she turned, moving her upper body against the ceiling and looking down at Jenna with a worried look on her face.

“I’ll… go get your clothes. Go out in the backyard. I’ll come out with you.”

Jenna offered as Miya nodded and smiled, leaning all the way down to hug her tightly as her face mashed against her enormous watermelon sized breasts, hot and slightly sweaty from her sexual morning exercise.

“Thank you! You’re the best.”

Miya smiled as she carefully went downstairs, wearing nothing, but a messy summer dress she slept in, now barely reaching her thighs as her pussy was on full display. She blushed moving past Janice who was busy trying to fit into the kitchen herself, wearing her bathrobe, barely covering her either, she was naked underneath, her own vagina easily visible from any bend over or stretch she would do between looking for something to cook.

“Good morning, sweetie!”

Janice beamed looking over her shoulder and then suddenly letting out a gasp as she straightened herself up to her full nearly eight and a half foot tall frame towering over her.

“Oh good heavens! What happened to you?”

Miya blushed looking down at her head now barely reaching her lips as she leaned down to see her face under her colossal breasts.

“I had another growth spurt. I need to shower… out in the backyard. Is that okay?”

“Oh… I… suppose that’s fine. Hold on, dear.”

Janice goes to the closet and grabs a few towels and tosses them to her.

“Use as many as you need, hose is on the left side of the house, honey. And do be quick. The neighbors are waking up now.”

Miya nodded as she went to the backyard door still blushing embarrassed that her growth has put her in a situation like this.

—

The height of the door once that towered over her before her growth into an amazon goddess, now barely reached the middle of her chest. She smirked and ducked under it, squeezing her ass against the doorframe, getting stuck again as she pressed harder, releasing herself.

“God… that’s getting old fast.”

She sighed and stretched her arms up into the air straightening out fully, no longer having to lean against the ceiling and looked over at the door now down under her shoulders and tits, as the height of the doorframe just barely reached the middle of her giant breasts.

“Holy shit.

THUMP.

Miya took another careful step into the backyard, and the ground seemed to sink into the grass and soil leaving an imprint behind in the shape of her bare foot.

THUMP.

At 8'5", everything around her looked absurdly small now. The patio furniture came barely to her thighs, the fence seemed strangely low, and the little garden shed that had once looked perfectly normal now seemed like a child's playhouse.

She glanced down at herself and shook her head.

“I'm seriously this huge?”

THUMP.

Another step sent her massive body swaying with the motion. Her shoulders rocked, her stomach shifted, and the rest of her enormous frame followed a moment later, making each movement feel exaggerated by her new size.

The watering hose was lying several feet ahead.

THUMP… THUMP… THUMP.

Miya walked toward it, then stopped.

The faucet handle was practically at ground level compared with her.

“You've got to be kidding me.”

She crouched down, bending her enormous frame almost in half just to reach it. Her long hair fell forward as she stretched one hand toward the lever.

She twisted it.

WHOOSH!

Water burst through the hose.

Miya immediately recoiled.

“Eep!”

The cold spray hit her skin, raising goosebumps instantly.

“Oh, that's cold!”

She shuffled backward, laughing and shivering as she tried to aim the hose at herself. The contrast was ridiculous. She was nearly tall enough to tower over the house, yet she was still standing in the backyard complaining about the temperature of a garden hose like an ordinary person.

She gradually turned the spray across her arms and shoulders, then down her legs, watching streams of water run across her enormous body and splash onto the grass.

For a moment, she simply stood there dripping wet, her long black hair down past her lower back like a raven haired curtain.

Nearly eight and a half feet tall.

Miya looked down at the hose beside her enormous foot and snorted.

“Everything is tiny now.”

She glanced back toward the house and strode toward the patio to get the towels.

THUMP… THUMP… THUMP.

Every time she shifted her weight, her gigantic ass bounced and swayed with the movement.

She reached up to the towels from the grass, easily grabbing them as she towered over the railing even standing on the lower section at her massive height.

The towel dabbed the water off her breasts, and nipples, as she tried to wrap it around her body and it fell short around her hips and giant tits.

“Ugh. Seriously?”

She pulled again as it came loose as she got frustrated.

“I’ll just… tie them together.”

Miya huffed, tying the towels together at the ends and moving it around her body, hooking her waist with one end and wrapping the rest around her huge ass and then to her other hip, as the final towel stretched across her breasts and fell short.

“Oh my god… this is so annoying.”

She untied the last one and used it as a dress top, wrapping it around her back and over her tits.

“Perfect… I guess this will have to do.”

She said sarcastically as she felt her hair wet on her back, turning to wring it out, squeezing the water out of her hair as it created an audible facet for a few moments spilling water all over the deck.

She sighed and stretched one more time as she felt the warm air on her cold skin looking back up at the sun.

“Today is going to be… interesting.”

The doorway was still visible through the open back door.

Even from outside, the scale difference was ridiculous.

The top of the doorway barely reached the middle of her chest.

Miya stared at it for several seconds before a slow, smug smile spread across her face before rolling her eyes.

“Here we go again.”

She looked down at herself again and laughed.

“I'm going to need bigger clothes…”

THUMP.

She took another step toward the patio.

The entire backyard suddenly felt like it had been built for someone half her size.

Miya grinned.

“Especially if I keep growing… bigger.”

She looked down and noticed the door knob was at her knee height. She giggled as her breasts jiggled in her makeshift towel-tied top, bending down to duck under the doorframe and get back inside.

“Ugh. Not again.”

She let out an annoyed sigh as her ass got wedged between the frames again. She huffed, pushing herself upright and ducking again as her head nearly bumped the ceiling.

“Everything is… too small for me now.”

Janice spun around anxiously and looked up at Miya struggling to fit in the house.

“Oh goodness, Miya, dear. If you grow anymore you won’t fit through anywhere in the whole house.”

Miya rolled her eyes and looked down at her explaining her situation.

“Yeah. Tell me about it. I know. I’m experiencing some kind of growth hormone overflow, my body is undergoing a rapid developing second puberty. I can’t seem to stop myself from growing… Hopefully I’m done for now. I don’t want to get any bigger.”

“Oh god. Does that mean I’m going to grow more too?”

Janice looked up at her and then back down to her enormous breasts, her long line of cleavage pronounced in her now too small ill fitting bathrobe.

“Honestly, I don’t know. I don’t quite understand how you grew so much off a third of a vial. Although that is still quite a large single dose considering I synthesized it to work off single drops.”

Miya began to realize what was happening. She gathered her thoughts, imagining a cell dividing and splitting and doubling itself over and over and her body growing alongside its process.

“Oh my god. Rapid Cellular Regeneration. I must have triggered it during my massive ingestion of the serum. It all makes sense now.”

She started searching around the kitchen for a pen and paper, knocking things over.

“Hey! Hold on there, missy!”

Janice tried to stop her fruitlessly grabbing at her arms, and she tugged on one, she felt like it was a tree rooted in the ground.

“Holy hell…”

She couldn’t even make her budge.

“Do you have a pen or a pencil? And some paper too?”

“Yes! Now hold on! Don’t make a mess.”

Janice called up to her begging her to stop as Jenna entered the kitchen looking up at her massive frame towering over everything in the kitchen including her own mother, who had already far surpassed her in height as well.

“Miya, what’s going on?”

Jenna slowly approached as she looked forward, seeing her eyes level with the middle of her giant breasts, caught trapped in the length of her massive cleavage between her massive globes.

“I think the entire vial caused my body to go into a RCR process, and I need to do some math. Do you have any paper or a pen?”

Janice interrupted handing her a pad of sticky notes and a pen.

“There! Work your magic, Miya.”

Miya’s massive hand gripped the pen and could barely hold it properly now at her new size, she struggled, pressing it down and causing the paper to crumple and the pen tip to bend. She sighed and dropped it realizing it would be too much effort to make it work.

“Ugh… seriously?”

Jenna looked over at her dropping the pen and her lips twisted into a knot.

“What’s RCR?” 

She asked, looking up at her massive frame.

“Rapid Cellular Regeneration. It’s when your cells split and make more. The serum loosens the hold on the nervous system to allow for it, so in larger quantities it may cause subjects to experience a second puberty, and grow… a lot bigger. I think that’s what is happening to me.”

Miya looked down, not noticing her nipples were swollen and puffy, and lactating slightly, making her towel wrap wet creating two damp spots. Her thighs squeezed together as she felt a shudder go up her spine.

“Among other things…”

Jenna looked up and her breath hitched.

“Your tits are totally leaking.”

Miya’s hands motioned down to her breasts, slowly pulling out one and squeezing her nipple watching milk trickle down her skin.

“Oh my god. What… When did this start happening?”

“I don’t know, I just saw it.”

“Miya! Cover yourself! Young lady.” 

Janice said as she blushed bringing the towel up over her nipple.

“I’m sorry…”

Miya blushed looking back at the bathroom as she turned and moved to go back upstairs feeling embarrassed.

— 

She rushed up and into Jenna’s bedroom making an audible sound with every footstep.

THUMP… THUMP… THUMP…

“Miya! Where are you going? Oh…”

Jenna followed up behind her as she ducked into her bedroom looking down at her giant ass wedged into the doorframe.

“God damn it.”

She struggled, pushing harder and harder until she fell forward onto the mattress, barely holding her even bigger body now.

“Finally.”

Jenna lowered her head and entered the bedroom looking down at Miya pulling off the towels and getting naked.

“Miya…”

Jenna said with a soft gentle tone, as she saw her bare breasts and her swollen nipples trickling with milk.

“Hey… can you do me a favor?”

Miya looked down at her and leaned over positioning her giant bare breast in front of her. Nipple dripping hot milk down in front of her lips.

“Suck on them… for a little bit… please. Help relieve the pressure.”

“Really? You sure?”

Jenna’s eyes went wide looking up at it, licking her lips and swallowing her mouth feeling dry.

“Yeah, please. I need it.”

Miya nodded, her cheeks flush and blushing embarrassed.

“Okay. Okay… just try to relax.”

Jenna lifted her arms and placed them around her breast, lifting it up slightly as she leaned in and placed her lips on her large nipple. It was swollen to the size of a grape and as soon as she applied a little bit of lip motion it began gushing squirts of hot milk into her mouth as she swallowed. 

“Mmmph…”

Gulp… gulp… gulp…

She eagerly swallowed down mouthful after mouthful of her potent hormonal milk, flooding her body with the same cells affected by the rapid cellular growth track, as she digested more and more, her blood stream flooded with her highly inflated hormonal growth factors rushed into feed her pituitary gland and start an endless churning process. More milk. More cells. More growth. 

“Ooh… that feels so good. Keep sucking. Please, Jen.”

Her head rose higher and higher, having to slowly bend over, leaning into her breast and nipple more, to suck down more, gulping down even more of her potent hormonal milk. Her breasts grew larger as well, slowly building on every few gulps as they jiggled and grew into juicy J-cups the size of basketballs.

“Mmmmmm…”

Gulp… gulp… gulp…

Jenna was growing at a rapid pace, passing 6’10", outgrowing her clothes she had just purchased as she grew even higher, clearing 6’11" as her head leaned in more taking up more space as Miya moaned and told her to stop.

“Okay… that’s enough… that was… amazing… now the other nipple… please.”

Jenna smirked and let out a cute burp as her body jiggled and rose higher, now passing seven feet tall.

“I’d love some more… tastes so good.”

Miya didn’t even notice her growth spurt as she moaned loudly, feeling Jenna’s lips connect with her nipples, sucking hard and faster than ever.

“Awhn… be gentle.”

The asian goddess let out a moan as Jenna’s lips sucked even harder making her yelp in a mixture of pain and pleasure.

Gulp… gulp… gulp…

Jenna pulled back for a second, breathing heavily as another warm shudder rolled through her body.

“Mmm…”

She looked down at herself.

Something was happening again.

Her stomach tightened as another wave of growth rushed through her, spreading outward from her chest and rippling down through her torso, hips and legs.

“Oh…”

She straightened slightly as she suddenly crossed 7’1"

Miya's eyes widened.

“Jen…”

Jenna looked down at herself, smiling as she realized what was happening.

“Every few gulps…”

She swallowed again, pulling harder for more of her potent breast milk.

GULP… GULP… GULP…

Another powerful surge hit. Her shoulders pushed wider as her arms lengthened.

Her thighs thickened beneath her shorts, forcing the fabric tighter against her rapidly expanding body as she passed 7’2".

“Miya…”

Jenna laughed breathlessly.

“I think your milk is making me grow.”

Miya stared down at her in disbelief.

“That’s… impossible… that means I’d be producing my own natural version of the serum.”

Her breath heaved looking down at her as she blushed watching her rise again, growing even bigger to 7’3".

“Fascinating…”

Miya watched the intensity in Jenna’s eyes as she looked up looking devilishly.

“I want more… mmph…”

Jenna’s already large lips wrapped around her nipple again and sucked down more nibbling on her nipple back and forth.

Gulp… gulp… gulp…

“W-wait… don’t… awhn…”

Jenna swallowed another mouthful before Miya could pull away.

Her entire body suddenly shuddered.

“Mmm!”

Her legs stretched first, longer and longer as she grew to 7’4".

Her thighs thickened against the fabric alongside her round backside.

Her hips pushed wider, tearing open the button on her shorts as her ass consumed more space.

Her stomach tightened as her torso lengthened rapidly upward as her breasts grew even bigger into massive soft and round K-cups.

“Jen!” 

Miya raised her voice just enough above a whisper as she couldn’t get her now rapidly growing friend to stop sucking on her enormous milky tit.

“Mmmmm…”

Her wet lips coated in her warm liquid began to swell, growing larger and more plump as she sucked in more of her lovely warm growth hormone infused breast milk. Her tongue eagerly moving back and forth against the underside of her enormous swollen nipple, sucking it for every last drop.

Gulp… gulp… gulp…

Another surge hit Jenna almost immediately, rising up past 7’5".

Her shoulders rose higher and her arms lengthened as her curves continued expanding with her.

The waistband of her shorts strained harder around her hips.

Her shirt stretched across her chest, pulling so tightly that the fabric began trembling against her expanding curves.

RIIIP!

“Mmph!”

Jenna let out a muffled gasp as the seams finally gave way.

Her bountiful breasts grew into absolutely titanic L-cups, each the size of volleyballs, jiggling madly on her chest as she pressed them forward into Miya as she blushed still watching Jenna sucking down all her breast milk. She could see her head rising higher and the rest of her body trembling with growth spurts continuously as she grew past seven and a half feet tall.

“Oh god… Jen…”

Miya reached down between her legs and felt her clit throbbing and aching for her touch.

“You’re growing so much…”

Her large hand stroked the back of her head watching her hair now flow down towards her enormous ass.

“Mmmhhhmmm… mhn… mhn… mhn…”

Gulp… gulp… gulp…

Jenna simply nodded in a haze between each gulp she moaned softly muffled against her breast, pushing for more and more as she sucked and swallowed down every last drop that was available in Miya’s two massive M-cup breasts jiggling on her chest with every rhythmic suckling of Jenna’s lips against her swollen nipples.

“Mmmhhhnnn…” 

She let out a long satisfied moan muffled against her nipple as she felt her entire body bloom in size growing several inches taller all at once. Her body rumbled, growing three inches taller to 7’7" to 7’8", then suddenly to 7’9" tall.

“Oh god… the growth is compounding. You have to stop Jen–”

Miya tried to push her away, but then suddenly she boomed in size again growing enormous as she pulsed to 7’10" then 7’11" and then she grew past eight feet tall.

Jenna forced her way toward her nipple, sucking every last drop as she drained her milky titty dry. Her cheeks hollowed as her throat worked every single gulp of more and more of her milk as she started to feel it stop giving as much milk until just a tiny trickle remained letting it pop out of her large luscious lips.

Gulp… gulp… gulp… gulp… gulp… gulp…

“Mmmmm… aaaah… so fucking good.”

Her body trembled with pleasure as she grew even bigger, her body surging with more growth hormones flooding her pituitary gland. She nearly came from the sensation alone. Her mouth opened wide as she started to feel the pressure against her breasts growing rapidly as they grew into giant breasts the same size and round jiggly softness of Miya’s M-cup proportions.

“Well… I guess my nipples do feel way better… so thank you for helping me with… all that.”

Miya blushed looking down at her sudden jiggly bounces as she rose taller every few moments having short growth spurts. Her body expanded and grew bigger pasing 8’1", then 8’2", then even bigger to 8’3" laying atop of her starting to smother her.

“You’re… nngh… so welcome… mmhhn…”

Suddenly Jenna began growing to match her entire size as she rose up another sudden few inches.

“Awhn… fuck… god… it feels… so… GOOD!”

She shouted down at Miya as she grew past 8’4", then 8’5" matching her size as she laid atop of her squishing her breasts against hers as they leveled out to the same height and proportions.

“Jenna… you’re still growing… How is this happening?”

Miya looked back up at her as Jenna’s eyes were lidded and heavy. She gave her a worried stare as she replied with a seductive glare, moving closer and matching their large lips together.

“I don’t know… aren’t you the biochem nerd?”

Jenna gave her a peck on her lips, connecting as she moaned into her mouth using her tongue to dance around with hers for a few moments, catching her off guard, before stopping by biting on her lower lip and only letting it go until she was a bit farther out between their lips.

“I like it. Mmmhhn…”

Then her body trembled slightly as her pussy gushed with wetness, feeling her clit pressing against her. She belted out a moan as she grew even bigger expanding past eight and a half feet tall, shaking with pleasure.

“Oooh.. my god…”

She couldn’t hold back anymore as the flood of growth hormones rushed through her body. Her entire frame suddenly stretched upward, carrying her from 8'6" to 8'7".

The change didn’t stop there.

“I’m still getting bigger…”

Her already massive breasts swelled outward, her chest becoming even fuller as her bust expanded toward her new N-cup proportions. Her waist thickened along with her torso, while her hips pushed wider and wider beneath her.

Another surge ran through her growing to 8'8".

Her thighs rapidly thickened, gaining heavy layers of new mass as they spread farther apart beneath her enormous hips. Her backside grew outward dramatically, becoming rounder and heavier until her enormous hips gave her a much thicker silhouette than she'd had only moments before.

She gasped as the final wave hit.

Her entire body seemed to become heavier at once. Her breasts pushed farther forward, her hips widened again, and her thighs became enormous pillars beneath her. Her backside swelled with the same relentless growth, adding even more weight to her already colossal frame.

Then, with one last powerful surge, she rose to her full height of 8'9".

Jenna stood there, towering over everything around her, her newly massive N-cup breasts, nearly sixty inch waist, and almost a hundred inch wide hips giving her an extraordinarily thick, curvy figure. At nearly seven-hundred pounds, much of that new weight had accumulated through her hips, thighs, and backside, making every movement feel heavier than before.

She slowly looked herself over, stunned by just how much bigger and thicker she'd become.

“Fuck…”

Her pussy gushed running down her thighs as her eyes rolled back and fluttered.

“Oh god… no… not again.”

Miya’s eyes widened as she felt Jenna’s body let go on top of her crushing her slightly as she giggled trembling and jiggling against her, smothering her as she’s now four inches taller than her.

“Mmmhmmm… I grew even bigger than you. You have some magic tits, Miya.” 

Miya turned bright red in both cheeks as she grew even more worried.

“But… Jenna, what are we going to do? How are we going to go to class? What are we going to wear?”

Jenna grinned still towering above her as she lifted herself up and stared down at her.

“We’re part of the “upper class” now. We can do whatever the fuck we want. Nobody can tell us what to do at this size. We’re so… fucking… big.”

Miya looked up and blushed her cheeks toward her.

“Yeah… we are.”

Nodding in response, but more so not to cause her any stress, and also that she was bigger than her now.

“I mean, I shouldn’t be too surprised I would experience extreme side effects from ingesting an entire vial of the serum at once, but I didn’t expect this.”

“You did good. So good. This serum is perfect. We need to make more.”

“What… No. I can’t produce anymore for anyone, that could be… disastrous.”

“Oh come on, imagine we give it to any new girl who we like and trust and then help them grow into towering goddesses, and then we can literally grow our own Cheerleading Squad! Think about it!”

“No, nobody else can know about this. I wasn’t even planning on having Janice try it and look at her! She’s enormous.”

“Oh god. She’s probably so short compared to me now.”

“Exactly! We don’t know how much this serum is still affecting us or what other variables may occur. We need to find clothes and get to class and figure this out. I need to get into the lab. What the hell can we even wear at this size?!”

Miya began to freak out as Jenna leaned in and gave her another big wet kiss.

“Relax. Let’s just figure it out together.”

“Together. Yeah.”

They both kissed, their large lips colliding against each other as the morning sun dwindled in the sky outside.

It was only getting later as they had already missed the first bell signaling that classes had just begun.
