Day 2

Home

Laura let out a cute moan as she stretched her long muscular arms over her tall shoulders, she fluffed her long brown hair that had grown even longer down her arched back just above her giant bubble butt. She raised an eyebrow feeling her long hair, holding it in her hands as she blushed a deep red. "Whoa...my hair grew longer...this is so cool!" She exclaimed as she jumped up feeling her entire body jiggle as she felt her feet collide with the soft grass. The growth serum and infused breast milk she drank had been building a compounding effect on her already muscular and jiggly curves. Her now mammoth breasts jiggled on the powerful upper half of her tall and seven and a half foot tall amazon-sized luscious body. The tingle of wind kissed her hard pink nipples sending a delicate shock into them as she cooed pouting and grabbing them as she squeezed harder, moaning and biting her lip as she softly responded in a sultry tone. "I'm so full and busty...nngh...my boobs are probably twice the size of Tiffany’s head...god they're so big...and bouncy. Gosh the rest of me is even sexier look at this fucking big bubble butt...unf…so juicy." She bit her lip as she looked down, squeezing her giant bubble butt sticking out from her curvaceous towering body.

She could feel her powerful thighs slapping together as she stomped forward a few steps, watching her big bouncy ass jiggle in unison, swaying with every step toward her quaint suburban home. "Man I've gotten so...big...I didn't realize just how tall I am now...I feel so fucking powerful...I wonder what Howard is going to say when he sees the new…bigger...me...I hope he isn’t mad…" Her heart started beating faster as she began to pant thinking about growing even bigger, she clenched her teeth trying to resist the urge to finger her wet pussy. "Nngh...fuck...I need more of that growth formula...nngh...it tasted so good...mmph...I want more...I wonder if there's some more in the lab...I want to grow huge...hahaha...mmm...I bet If I was a little bit bigger I could smash her stupid Nissan." Her thoughts wandered as she giggled devilishly imagining herself smashing her sister's SUV with just her giant overgrown body. She couldn't resist any longer, she felt her vagina throbbing and pulsating as she moaned slowly moving down to her crotch. Her fingers danced around the rest of her body, slowly inching their way towards her aching vagina. She moaned, trembling as a squirt of cum trickled down her wet pussy, slowly dripping onto the pavement as she clutched her massive breasts again, begging for attention. She tried to resist, barely able to strip her hand away from petting her pussy, moving her thumb over her swollen red clit as she stuck out her tongue for a moment, trembling again in pleasure. “Ooh... it's so sensitive...awhn...fuck I’m so horny...it’s kind of cold out here though...I should go inside and find her.”

She started to approach the driveway swinging her wide hips and big ass around, approaching the blue SUV sitting in the lot alone. It seemed much smaller beside her new size, she grinned placing her hand on the roof comparing her amazon size up against the driver-side window. “Hmm...looks like Tiffany is home, but dad’s not here...he must be with that Victoria lady…god I'm really tall...it looks so much smaller now…my ass is the size of the entire window...unf...” She blushed, starting to quickly get excited about her new powerful body, getting wet imagining the look on her sister's face. “Oh my god...she’s probably fucking tiny compared to me now...I have to get inside and find her...”  Her feet made an audible crunch and crackle as she stepped onto the old wooden steps looking down at towering body jiggle as she made her way up. "My legs are fucking enormous, I could crush someone between these thighs...If I get any bigger I'll probably go right through the damn deck." She grinned devilishly approaching the front door as she reached down to her waist out of reflex, realizing she wasn’t wearing any pants. “Oh...shit…” She softly spoke in the night air as she ruffled the tangle of sweaters wrapped around her body, looking for her keys. She struggled, not finding much as she huffed and puffed looking down at the doorbell smiling, suddenly changing her mood. “Actually...this is a perfect time to finally get my revenge...mmm...hahaha…”

She softly bit down on her big juicy lip and she raised her finger to the doorbell, ringing it, giggling as she moved her other arm under her breasts, to avoid her top from falling off. She waited a moment, noticing the top of the door frame shorter than her new height after her recent growth spurt. “Holy fuck...I’m taller than the front door...I’m going to have to duck...to get inside…nngh...why does that turn me on so much...” Suddenly her eyes widened and her ears perked up as the sound of footsteps began echoing and moving towards the door, she blushed even harder when she saw the doorknob turning, feeling her pussy begin to throb with pleasure in anticipation. The door opened slowly with a resounding creak revealing a tall dirty blonde haired girl dressed in a sleeping gown, she yawned for a moment before opening her eyes confused. Her eyes noticed a change in light, a long shadow had cast over her and the rest of the foyer as her eyes slowly panned up to see a voluptuous seven and a half foot tall amazon blocking the moonlight.

She gasped and stood there completely stunned, like she had seen a ghost, pale and shocked, staring forward at her sister’s powerful new hourglass figure silhouetted in the moonlight, shining bright like a goddess. Her eyes were now level at the bottom of her giant juicy tits, several inches shorter than her tall shoulders. She was totally lost in her luscious curves and muscular features, panning her eyes slowly up her strong and seductive figure, nearly drooling at her towering thickness and divine beauty. Her busty breasts blocked most of the vision to her face as she giggled, grinning devilishly behind them, she leaned down and thrust her chest forward throwing her arms behind her back in a cute fashion. “Hey, sis! I’m back!” Her two incredibly large melon-sized breasts swayed around her chest, she giggled again, moving closer towards her, trying to duck under the doorframe and squeeze inside. “L-laura…?” - “Who do you think it is?” Laura laughed standing back up to her full height, immediately intimidating her again as she gulped nervously in response, trying to formulate a proper response. “Move aside, shorty.” Laura pushed her way inside, shoving her away with ease. “Ugh! What the-” Laura was overzealous, she shoved her into the door, trying to push lightly, not realizing her new strength and size as she heard her back collide against the door loudly. “Ow!” - “Aww...come on I barely pushed you, you’re so weak compared to me now…” Laura giggled, looking down at her sister rubbing her shoulder starting to tear up as she tried her best to show a brave face. She wouldn’t back down, letting her pride poison her feelings, starting to torment her mind. “What the fuck!” She screamed, looking at Laura with rage as she immediately responded with a cackle out of pity.

“Aww...what’s wrong Tiff? Don’t like being pushed around?” - “What happened to you, how did you get so...big…?” - “Mmm...wouldn’t you love to know...hahaha!” - “You can’t be fucking serious...you gotta turn back, right now!” - “Turn back? Actually...mmph...I was thinking of...getting even bigger.”  - "Bigger?! Are you crazy? You're already a giant freak!" Laura's mood plummeted, she started to look sad at first until she slowly started to crack a devilish grin. "What...did you say…?" Tiffany watched her rise above her, looking down and stepping towards her as she ducked down to avoid the chandelier at her height, nearly knocking into it with her amazon height. She stood up to her full height, looking down as she began to ruffle her sister's hair, latching onto her head with her powerful hands as she softly spoke menacingly, “I’m going to grow even bigger...and bigger...and even bigger...and there’s nothing you can do to stop me, not being that fucking small at least...hahaha!” - "Argh! Get off of me…Laura...stop!" She stepped back a few more steps when Laura began stomping closer, adjusting herself as she kneeled down and suddenly grabbed onto her under each of her arms like a child. "Come here...little Tiff...nngh!" - "Hey! Whoa!" Laura whisked her into the air with ease, lifting her up to her larger upper half as she grinned devilishly watching her legs dangling off the floor. "Put me down! Right now!" Tiffany demands, shuffling and trying to escape her sister's new amazon arms. “You’re so light! Hahaha! You're so cute when you're helpless...” - “Put me down, now!” Her hands easily wrapped under her arms, lifting her to greet her with a mean-spirited smile as she laughed out loud, looking at her feet dangling off the floor just above her towering knees. "Or what…?" Laura toyed with her, laughing and gripping her tighter as she struggled and started to grunt feeling her huge muscles begin to tense up flexing against her weaker body. "Ugh! Stop! I said, put me down!" Tiffany was powerless against her now, her nearly six-foot-tall athletic body was no match for her sister's over seven and a half foot tall growth serum enhanced physique, she was towering from head to toe in powerful womanly curves covering sheets of built muscle. She had over a foot and a half of size advantage over her smaller sister, who was taller than most of her friends already.

Laura was barely exerting her full strength, lightly holding her felt incredibly empowering, she had remembered the days of torturous bullying that Tiffany had been dishing out for years in their youth, recalling all the memories of being weak and unable to fight back. She laughed again, dragging her body deep into her breasts, jiggling and giggling as she responded in a sultry mocking tone. "God aren't you just the cutest thing now...mmph...yeah...do you like your sister's big soft titties?" - "Mmph! Laura!" Her mouth moved around the wide surface of her silky bouncy breasts, unable to stop her from mashing her face against them repeatedly as she gasped for air, starting to struggle less with every failure. Tiffany was trapped between her giant tits unable to escape to even do anything as she felt totally weightless being tossed around the air without effort. Eventually, Laura lifted her back out of her clutches, holding her gasping and panting sister as she looked at her messy hair and red messy face. "You look like shit! Hahahaha! She cackled maniacally as she blushed a deep red, finally feeling like she had gotten revenge. Tiffany pouted, saying nothing, feeling her frizzy hair surrounding her blushing red face. Laura was giddy, she couldn't stop herself from giggling like a schoolgirl, turning more devilish as she suddenly tilted her head and let go. "Hey! No!-" Before she could say a word she was already on the floor. Her legs cracked on the hardwood floor as she yelped in pain, the rest of her body landed, feeling her shoulder hit the hardest as she winced, grabbing onto her arm and looming back up at her amazon sized sister, towering above her, nearly reaching the ceiling at her incredible height.

She continued to laugh as she blushed looking down at her sister still recovering from her fall. "Get up." She commanded as she looked at her in disgust, suddenly latching onto her arm and raising her up to a standing position. She started to measure her head, resting her large hand on her head and then moving it up against her massive bustline, measuring it somewhere at the bottom of her breasts several inches below her shoulders. "Ugh! Get off of me! Enough already Laura!" - "God you're so short! My big boobies are taller than you now...I just wish you were even smaller...hmm…I have an idea." Laura continued to grin while she schemed, brushing aside her shorter sister as she watched her massive body stomp her way out of the foyer. "Smaller?! Laura! Get back here!" She rushed down the hallway, moving towards the kitchen, turning halfway as she thrust open the basement door, ducking down and climbing down the now cramped staircase with a bit of struggle. Laura ducked down trying to get past the light fixtures at her new size, finally standing downstairs at her full height as she approached the desk full of samples in the botanical lab. She looked across the table searching for more of the growth serum, panning over everything, shuffling through the different containers strewn across the surface, when she spotted a new vial, hidden in the back of the rack. "Howard is so tall...he must have put it back here to hide it." She thought to herself as she plucked the bottle out of the rack and opened it, finding it quickly without trouble at her new height. A powerful herbaceous aroma wafted from the bottle as she twisted off the cap, she looked inside, inspecting her findings, it was much more green, almost a spinach-colored oil. She tilted it for a moment, watching the deep green viscous liquid move around very slowly in the vial as she began to salivate. "Ooh...this must be the triple strength blend of the growth serum he was making before...I wonder how much bigger I would get if I drank the entire bottle…let’s give it a taste first." She grinned devilishly and tilted back the bottle resting it on her bountiful lips.

“Gulp.” She took a sip, tasting it and starting to blush as the familiar feeling started to rush through her senses. It had the same flavor, flowery and sweet, however, this blend was much stronger, it was sickly sweet at first, followed by an addicting potent flowery flavor she couldn't resist. Her lips grew to puff up bigger as her body suddenly pulsed jiggling all at once as she gulped down more. "Mmph...mmm...delicious...mmm...gulp gulp gulp…" Tiffany approached hearing the sound of loud, yet vocally soft muffled moans followed by gulping as she watched her sister's bountiful lips wrapped around a vial sucking down its contents, guzzling down even more of the powerful growth serum. "Hey! What is that...oh no...Laura, Stop!" Tiffany protested latching onto her wide hips with her shorter arms as she struggled to even make her flinch. Her arms barely could wrap around her massive ass pushing her away from her waist and tall arms. "Laura! Stop, you'll get too big! You won't be able to fit inside the fucking house! Laura!" - "Mmm...that sounds amazing...mmph...more…I'm going to grow huge! Mmm...gulp gulp gulp…"

Laura smirked as she continued sucking down more, quickly finishing half of the vial in a few big gulps as she felt a shudder shoot through her body, suddenly moaning loudly as her nipples became increasingly sensitive, getting harder and swollen red as she trembled in immense pleasure. Tiffany had her arms wrapped tightly around her massive hips trying to push her away, fruitlessly to reach and grab her arm as she tried to stop her from drinking any more of the extra-strength growth serum. "Mmmm...you can't stop me anymore...I've gotten too big...mmm….hahaha...more...bigger...mmph…" Laura went back for more as she licked her lips clean, drinking down more of the concentrated growth serum, she felt the potent serum slowly drain down her throat with her huge jiggling ass facing her sister underneath her, nearly smoothing unable to make her budge. She ignored her, looking at the bottle with only about a third left inside when suddenly she started to feel extremely dizzy, her vision began to blur as her body pulsated with erotic sensations starting to make her cum without even touching herself, she panted heavily slowly twisting the cap back on as she moaned loudly clutching onto the table under her. Laura turned around sitting onto the desk with her huge ass as she placed the vial on a tall shelf, above the workstation, licking her lips and feeling them begin to swell even larger. "Mmm...I'll just put the rest up here for later...your little arms can't reach up this high...hahaha...oh!” Laura felt another wave of euphoria wash over her as her legs felt weak, starting to tremble, falling back onto the table as she moaned, feeling her pussy throbbing out of control. She gasped, letting out a hot breath as she started panting and sweating, her body started to feel numb as she couldn’t move, her hands started to slip as she suddenly began clutching onto the desk harder barely able to stand on her two massive legs. Her hands sunk into the metal, starting to bend it as she let go feeling her heart beating faster and faster.

"Laura…are you...ok?" - “Argh...nngh! My body...is on fire!” Tiffany started to see it for herself, her sister began to grow bigger again, moving back slowly as she started to watch her ass bubbling bigger, watching it begin to make her body rise upwards as her legs grew thicker and longer inching towards the floor beneath her expanding body. Her massive bubble butt surged with growth becoming over double the width of her torso and still growing in size as she moaned in response. "Ahh! It feels like...my whole body...is numb...nngh…I can’t...move...awhn!" Her voice boomed as breasts began growing bigger and bigger and even bigger as they began spreading out over her tremendous thighs, expanding into giant beach balls filling up her lap, bubbling and becoming massive as they touched her thick thighs. She gasped as her sister's long legs grew to fill the space in front of her, she moved back, watching it grow even bigger, stepping back again as she only grew larger. She watched her sister grow inch after inch taller to 7'8 and then again as her ass expanded even outwards even larger growing into a powerful 7'9. "L-laura...how much more...did you just take…?" - "Mmm...ahh...oh my god...aah...I’m so fucking horny..." Her body bulged, growing again as she began stretching out longer, becoming more powerful as she grew even bigger to 7'10 as she started to moan, slowly trying to get up from her paralyzed sexual state. "Awhn! YES! I feel it all over my body…I want to be fucking huge!" She screamed again as she started to increase in size rapidly, her arms began stretching across the table becoming longer and more muscular, growing stronger and larger. She grunted feeling her body grow another inch taller to 7’11 and then again in a large growth spurt as she towered upwards to 8’0 feet tall. Her fingers started to penetrate her incredibly wet pussy as she moaned loudly, licking the green growth serum off her now puffed-up juicy lips, letting out constant loud bursts of pleasure as moaned in pleasure. “Bigger! Bigger! BIGGER!” She roared demanding more growth as she began to climax bursting with energy growing even more colossal, she surged rising inch after inch taller as she grew larger, then even bigger as she finally came in a massive growth spurt fueled orgasm. “I’m gonna cum! I’m...I’m...AAAAAHHHWN!” Her face flushed as she reared her body back as it began growing more rapidly than ever before, bulging and packing on strength and size in seconds, as she rose taller and taller, passing eight and a half feet tall, embracing a wet orgasm all over her thick thighs, running down her legs. She clutched them feeling her tightness begin to hold her in place, trembling with pleasure “Oh fuck…” Tiffany’s jaw dropped watching her sister continue transforming into a towering full-sized amazon, she gained size exponentially expanding all over.

Tiffany was speechless watching her sister start to roll her eyes back ignoring her and fingering herself even harder, her fingers thrust into her wet pussy as she moaned loudly. Her tied-together sweaters acting as her only thing covering her giant tits suddenly started to unravel. They began to fall off as she started playing with herself roughly in lustful hypnosis. She could barely think as her vision began to blur making out the movement of her sister now running up the stairs. "Wait...stop...awhn! Come back...haha...mmm...oh fuck..." Laura was helplessly fingering her soaking wet pussy. “Ooh...fuck! I'm gonna cum again! Awhn! Oh god!” She suddenly came again, surging in power, growing even larger as she moaned loudly increasing in size. She trembled growing inch after inch as she rolled her eyes back sticking out her tongue starting to laugh menacingly and biting her lip in twisted pleasure. She surged upwards growing up to 8'9 feet tall closing in on her next growth spurt as she opened her eyes watching her sister holding her breath frozen in fear. "Oh my god...I just keep growing...it's turning me on so much...let's get out of here...mmm...I want to see how big I’m getting." She grinned devilishly as she started to stand up, ducking her head below the basement ceiling as she tried to move towards the now much smaller staircase. "Woo! I'm so much taller now! Yes! Ooh...It's really dusty up here." She giggled as she was towering over her sister, she stomped by her, trying her best to avoid bumping her tall shoulders and head into the ceiling rafters. Her massive feet collided with the staircase, letting out a loud wooden creak as her amazon body applied its weight to the step.

Her massive bubble butt jiggled as her sister watched her crawl up the steps towards the door with some struggle, she peered over to see her muscular arms latching onto the wall outside the door at the top of the steps, flexing and ducking again to get out noticing again just how much her height had shifted even taller. She finally made her way into the living room as Tiffany followed her watching her ducking to move around until she finally entered the main room starting to stretch her arms toward the ten-foot-tall ceiling. "I can almost touch the ceiling...I must be so tall now...oh my god...look at you down there...hahaha!" Laura blushed a deep red as she stomped toward her sister who's eyes were now staring below her belly, near her neatly shaven crotch and wet vagina. She gulped seeing her sister's tall and voluptuous body growing even bigger as she cooed, placing her hand on her head and shoving her closer to her slightly trembling growing body. "Ugh! Quit it!" - "Oh my god Tiff, your shoulders aren’t even as tall as my hips anymore! Hahaha...so small and...weak...nngh...fuck it's turning me on so much...awhn!" Tiffany struggled to try to push her away as she felt her hand completely engulf her head, playing with her hair as she moaned starting to grow even taller. Laura brought her head in closer, smothering her with her massive curves as she started to pulse with growth. She could feel her hands wrapping around her head even more as she felt her getting smothered even further as she rose taller and taller, her perspective lowered down towards her soaking wet pussy as she grew bigger and bigger and even bigger passing 9 feet tall. Tiffany’s perspective shrank lower and lower as she watched her titanic amazon sized sister become gigantic, she watched her perspective slowly line up with her soaking wet vagina as she felt her sister’s grip on her head tighten pushing her face deep into her pussy as she moaned in response, now standing at a powerful 9’5 feet tall. “Nngh! Your...tiny little head is smashed up against my pussy...awhn!” - “Mmph!” She struggled, trying to escape as she pushed her head it again, harder with a bit more force as she choked trying to gasp for air. “Mmm! That feels amazing...ooh...are you trying to breathe? Sorry...let me give you a second...my tiny little sister...hahaha!” She cackled madly, finally letting go of her as she fell back onto the carpet under her, feeling her wetness all over her face as she coughed and scrambled away to the kitchen.

Laura couldn’t help it, she was filled with joy and power, continuing to laugh and moan in blissful glee. She held her huge breasts in her hands as she felt the sensation of overwhelming sexual heat cloud her senses.  She increased in size, starting to tower over everything around her. She rapidly grew past 10 feet tall, growing up and up and expanding into a ludicrous size. “Awhn...bigger...bigger! BIGGER!...Ow!” She felt her head bump the ceiling as she grew several inches in three large spurts of growth, quickly passing 10’4 feet in height. Her voice dropped as she rubbed her head, looking above her seeing the wooden rafters lining up to her eye level. “Ow....oh my fucking...god…” She bent downwards, pushing her big bouncy ass towards the fireplace, consuming the space around her massive body. She leaned down seeing her sister’s long blonde hair waving in the wind as she rushed down the hallway, towards the basement door. “Hey! Come back here! Don’t...go down there...nngh!” Her body pulsed again as she felt her muscles rippling and expanding, she grew, again and again, suddenly losing her balance as her giant bubbly ass slammed into the coffee table beneath her towering frame with a loud crack, splitting it into two jagged pieces. She grunted feeling her ass consuming the leftover bits of the table as it bubbled outwards expanding even larger. Laura’s body was growing faster as she passed 10’9 “Augh...what the fuck...did I just...oh!” She suddenly surged in size again, growing even larger as her body crushed the remains of the coffee table as she consumed it with her large growing bubble booty. It continued burgeoning in size, her legs stretched out from her body, rapidly reaching the table within seconds as she rose taller. “Oh my fucking god...it won’t stop...oh god!” As she began to pass 11 feet in height followed by another massive jolt in her system, feeling her body trembling with powerful cascading waves of bouncy curves all over her mini-giantess body as she surged in size even further, her hips slammed into the sofa, nudging it to the side, and then again and again as her hips began to overtake the height of the armrest. “Oh...look at how tiny the couch...everything is getting so small...oh...I feel it again...oh FUCK...awhn!” She moaned loudly, clasping onto her giant overflowing bust as she began to have another growth spurt. She watched the three sectional sofa begin to move further away from her increasing size.

“Oh...fuck…Howard’s not going to like this…” She kept expanding, growing taller and taller looking down at the sofa as she smirked devilishly, watching it push away from her growing ass, bubbling up against it. “It looks even smaller...I bet I could...pick it up with one hand…unf…” She bit her lip, feeling her strength coursing through her body, as she grabbed onto the couch with a single hand without warning and lifted it with ease. She was shocked, the sofa was as light as a potato sack, she couldn’t believe her newfound strength. “I’m...fucking strong...like really strong…” Her nipples began to tense up as she bit down even harder on her lip, starting to feel turned on by her immense power. “If I can pick up the couch...with just my hand...what else...can I...lift...oh...god...It’s so intoxicating having this much strength...mmm...I’m a goddess…” Her fingers dug into her soaking pussy as she moaned loudly feeling a surge of power wash over her, she fingered herself more, making herself absolutely uncontrollably horny. Her tongue stuck out of her hot, panting mouth as she drooled all over her big bouncy breasts, blushing a deep crimson. She grew and grew, fueling the fire with her powerful hands, pleasuring herself as the sofa started to move into the hallway from her increasing size. She felt her feet touch the TV stand, starting to push against the wall behind it as she grew into a towering 12 feet tall, passing any normal standards for an amazon-sized woman, growing into a mini-giantess.

Tiffany moved toward the stairs, her instincts kicked in and her athletic build carried the rest along, she raced down the basement stairs quickly as she made her way into the botanical lab not wasting any time. Her mind was suddenly assailed by the sounds of the ceiling above her creaking as she heard her sister continue to pleasure herself loudly, still growing bigger past her colossal size as her long legs grew even longer towards the table filling up the room with her size rapidly. She focused on getting the growth serum for herself and easily climbed on top, trying to avoid hitting the low-hanging lamps on the ceiling. She looked up, seeing a nearby shelf and the remaining bottle of growth serum. “Jackpot.” She said, smirking as she reached up and snatched it up, and carefully stepped back onto the ground next to the table. She pouted and twisted her lips looking at the bottle in her hands as she twisted the cap off and gave it a sniff. “Bleh...smells fucking gross...what the hell dad…Ugh. I guess it works though...fuck I need to get bigger than her...” She felt a chill run down her spine as another loud roaring moan came echoing downstairs. She heard things moving above her, scraping the floor as they were nudged aside, pushing towards the edges of the room upstairs. "Oh fuck...she's still getting bigger...how much of this stuff did she take, she’s already so fucking big."

Her bright golden eyes went wide as she moved her head to the side, letting her dirty blonde ponytail tied up with a red scrunchie fall behind her slender shoulders. She thought to herself, moving the vial close to her bright pink lips, slowly tilting it into her mouth before tasting it. “Two can play that game…mmph…” She tasted it, feeling the intense flavor coat her mouth as she coughed, trying to keep it down as she gulped. “Ugh...what the hell...it tastes so fucking weird!” Another loud crunch resonated from upstairs as the entire house shook for just a moment, startling Tiffany suddenly, her hands slipped spilling some of the serum directly onto her chest as she gasped in surprise. “Oh fuck!” She felt the cold trickle of the growth serum slowly move down her D cup breasts toward her tiny pink nipples. She cooed, feeling the formula drip down her shirt and towards her belly. “God damn it...ugh, I might as well finish the rest...mmph…*gulp gulp gulp*” She gulped again, holding the vial in her hands with some left as she quickly sucked down whatever was remaining, gulping down the last bits of the serum as she coughed more, opening her mouth to reveal a dark green color coating the inside of her mouth and tongue as the bottom of the vial was much more settled and concentrated. Her lips closed again as she gulped feeling sick for a moment as she licked her lips again feeling them starting to tingle. They began to puff up, growing more luscious and bountiful, kissing them together as she licked them again slowly and sensually feeling her tongue starting to feel a similar sensation.

She almost gagged feeling the thick sediment trickle down her throat, holding back the urge to cough it back up. She suddenly became vigilant and stiff, holding herself for a moment as the feeling subsided. A breath of relief washed over her, letting out a long sigh and casually placing the leftover empty vial back onto the table. "Mmph. God that so was so strange. I've never tasted anything like that before." Tiffany sighed again, looking down at her breasts, noticing the serum had absorbed mostly through her soft skin atop her decent-sized bust. “Huh...I guess that works.” She began moving up towards the staircase, walking up and closing the door. She waved her long hair behind her head as she coughed, feeling the residue begin to itch her throat and tongue. She sighed, turning the corner just slightly peeking her head out to see Laura still slowly fingering herself, she rolled her eyes watching her divine form continue to bloom. She was entranced by her sexual desires, dripping wet, and filled with powerful sensations, her huge powerful and strong arms continued petting her sore and massive aching vagina, not paying much attention to her surroundings. Tiffany heard a noise behind her as the door creaked open, a tall stern gazed man with heavily combed brown hair, and a bristly beard stood at the doorway. His two work boots treaded inside, taking off his coat when he slowly noticed Tiffany standing at the end of the hallway, closing the door behind him and raising an eyebrow. Howard was a bit confused, looking at her daughter hiding in the hallway, approaching slowly as he heard a loud moan followed by an even longer sigh echoed through the house loudly. He quickly made his way down the hallway and called out to Tiffany, “Hey Tiff, you ok?” - “Oh! Hi Dad…” Tiffany looked a bit curious as she turned and wrapped her arms around her father, before quickly crossing them under her small cleavage resting in her green tank top tucked away in her bathrobe. “Laura stole your growth drink thingy…” - “So it was her...where is she?” Howard responded quickly when he noticed it for the first time.

She started to grow bigger, her head slowly rose as she began to grow taller before his very eyes, she smiled in response, slowly starting to turn red and blushing as he watched her body begin to fill out. “She’s like...in the living room...mmm...sorry...I um...mmm…feel faint...awhn...”  She rose taller again, suddenly shifting upwards as she moaned out loud abruptly, stretching all of her clothes at once as she grew taller. Her body began to slowly fill out, it started down near her legs as they began to bulge and become thicker as they began to lengthen, growing longer and more muscular stretching the fabric of her tight yoga pants. Her robe began to look more seductive as her figure became more pronounced and more hourglass-shaped, growing more curvaceous rapidly packing on fat and muscle all over her soon-to-be-less athletic physique that began to pop out of her clothing. She cooed feeling a tingling sensation start to build in her thighs as she felt her pussy start to get wet, beginning to throb harder. Her hands trembled instantly moving them towards her aching pussy when she retracted it feeling embarrassed. “Oh! Sorry...I’m just...tired...mmm…awhn! Oh god! Sorry...” She cleared her throat trying to fight off the urge to touch her ass and chest as they began to become increasingly sensitive, bubbling up bigger and thicker as they began to press up against her braless top. Her cleavage became more visible as her big breasts grew bigger, bubbling up against her tight top. She jolted up another inch as her body grew taller again to 6’0 feet tall, still increasing in size as she embraced him, hugging around his wide shoulders. “Hey...welcome home dad...nngh…” - “Oh Tiff…” He felt her arms beading with sweat as he recoiled softly, looking at her eyes begin to line up against his own growing bigger again as she rose to his height at 6’1. “My god…” - “What…?” She played coy, opening her big golden eyes as she yawned, crossing her arms again, pushing up her breasts as he let go. “Hmm...is something different?” He looked down at her chest seeing her nipples begin to puff up getting rock hard as they grew starting to pass DD cups in size. “Tiffany…” She smiled, feeling the sensation returning again as she rose upwards, watching her perspective rise again as she grew taller again, starting to grow bigger than him, passing him rising up to 6’2. “Oh no...not you too…” - “Mmm...you should see how big she has grown already...awhn...she’s fucking gigantic...the least you could’ve done was...give me a sample first...nngh.” Her body trembled again, growing taller as she pouted, starting to fondle herself, caressing her growing breasts as she rose to 6’3. “Tiff...I didn't give you any because the formula wasn't designed to be given to people...How much...did you take…?” Howard cleared his throat starting to get nervous as his eyes wandered toward her tight tank top that began to fill up, showing her pale skin and belly as it rode up her chest.

Her hand slowly moved across her belly looking down as she watched her body grow out of it. She only grew bigger as her tight green tank top began to shuffle around her growing breasts, a line of cleavage began to build and build, filling up bigger as she grew up another cup size to DDD cups spilling over her tight shirt. Her hands immediately wrapped around them, holding them juicy and jiggly size as she nearly squealed in glee. “Oh my fucking god...I’m really growing...awhn!” Howard didn’t stop her, he stood there in shock as she rose again and again, inching upwards larger with every second as she grew to 6’4. He watched her body begin to grow more curvaceous and powerful, becoming bigger and stronger than him as she started to grow faster passing 6’5, giggling and cooing as her body grew and grew.  Howard gulped seeing her growth spurts accelerating as she grew taller and more busty passing F cups and then even larger as they began to create a tear in the fabric of her tank top. “Oh fuck...awhn!” Tiffany began panting as she felt her legging start to ride up her shins toward her knees as they buckled, feeling the sensation building up within her pussy. Her body trembled as Howard tried to move past her, she looked down at him watching her perspective rise again and again with another growth spurt, passing 6’7, his eyes trailed up to her face that began to slowly move out of perspective replaced by her neck and then slowly down to her enormous cleavage as she continued sprouting upwards, growing and growing into a luscious amazon. She grew rapidly as she passed 6’11 feet tall looking down at him now an entire foot taller than her original height as she tried her best not to laugh out loudly looking down at her father, who she had recalled to be quite tall and powerful, looking at the top of his head nearly lining up to the bottom of her chin.

“Oh god...he looks so small now…” She thought as he quietly moved by her, she gasped as he walked into the kitchen finally releasing herself from his vision as she moaned, feeling her tank top snap off flying to the floor as she grew into huge G cups, barely able to contain them in her arms as she cooed and bit her lip watching them expand larger. She looked up for a moment, smirking as she watched him pass into the kitchen, trying to quiet her incessant moaning as she felt her leggings shred and rip off her thickening legs. They grew longer again as she couldn’t hold back and longer, digging her fingers into her pussy as her entire body trembled with intense euphoric feelings. “Oh...fuck I’m so horny...I need...nngh…to...fuck...” A jolt ran through her system as she suddenly grew past 7’2 feet tall, growing bigger again as she suddenly felt her panties tear against her growing giant ass. It expanded, ripping them further as they rounded out, widening her hips against the stretching fabric as another jolt of intensity ran through her system, forcing them to finally shred off. “Holy shit…” She thought as her bouncy ass jiggled wildly, she stuck out her tongue and began fingering herself, soaking wet and enthralled. “I’m so fucking...thick..nngh…” With every thrust she grew taller, feeling her ass slowly sliding up the wall, she grew bigger to 7’6 feet tall, nearly reaching orgasm as she cooed, biting her lip and letting herself go wild. Her other hand dug into her right breast that had been growing exponentially, bigger and fuller as they bubbled up into H cups and then even larger past J cups as she moaned louder, penetrating herself deeper. Her hair began to lengthen rapidly, growing longer and fuller as she plunged into her wet vagina, insatiably pleasuring herself to no end, her legs only grew more powerful, feeling the growth serum fill her body out literally began to turn her on even more as she grew taller to 8 feet tall, now over two entire feet taller than her original size, stomping and fidgeting in the hallway above a pile of her own shredded and destroyed clothes. He entered the kitchen nervously looking behind him for a moment back to his other growing daughter now completely naked and absolutely filled out all over, starting to enjoy her new fully grown body. He watched her for a moment seeing her body ripple and jiggle with power and growth as she started to peak in her growth around 8’3 feet tall, having to duck her head down from hitting the low foyer hallway ceiling as she continued to giggle and caress her body.

His senses wandered back towards the seductive sounds coming from the other room, listening to the loud moans and seductive sounds echoing through the tall living room space. “Laura…?” He called out swallowing his fears as he heard shuffling scanning the large living room space in the dark as he started to notice shards of broken wood beneath her towering gigantic bottom half, smothering everything in its path. Howard stepped forward, walking past her incredibly long and powerful legs as he approached her giant trembling body. She slowly opened her eyes looking down to see her father as she gasped, quickly moving her arm to cover her massive breasts, the other moving down to place her hand over her wet pussy to hide it from prying eyes. "Dad? Oh god...I'm so sorry...I kind of...outgrew everything...hahaha!" Laura laughed sending waves of cascading jiggles throughout her amazon physique. "Laura...why did you take so much and why didn’t you tell me…I'm not mad...I just would've really preferred that you work with me on your progress for my research..." Howard was baffled at her new size, his eyes couldn't help but scan her new giant-sized size attributes. "I'm sorry…I got carried away...I just wanted to get bigger...and bigger...now I'm …fucking humongous." She blushed, feeling guilty as she pressed her breasts even closer together as she looked down at him beneath her towering size. "How are you going to get outside...how are we going to feed you…" He kept prattling on and on as she just got more embarrassed, listening to him calculate the logistics of taking care of a real giantess in your own home. "Dad…nngh..." Her body trembled as she watched her perspective begin to rise again as her body grew and grew as he continued on. "It's going to be hell at the grocery store…" Her legs began to buckle against the stairway down to the den as she felt her toes curl up against the length of the entire step slowly growing bigger. "Howard!" She shouted echoing through the house when she suddenly surged in size smashing into the wall behind him. Her head bumped the ceiling, smashing it above her, sure enough, she was outgrowing the room now, pushing up against everything around her as she yelled trying to stop herself from destroying the house. He stammered, stepping back as he watched her grow and grow until the massive growth spurt stopped her around 14 feet tall. She started to whine, struggling to contain her powerful curves busting out and bashing over everything around her huge one-story-tall giantess body. Howard mumbled to himself as he climbed over her huge leg now resting across the entire length of the kitchen. "Got to make a reverse serum…" He jumped again moving down to the basement door as he opened it, suddenly feeling it shut close.

He looked forward to seeing a giant hand, outstretched and forcing the door shut as Tiffany leaned down to him and smiled devilishly. "Tiff! I need to make an antidote, please!" She smiled as her body began to tremble slightly, he watched her handshake for a second and then bulge bigger and then again and again as she began leaning over more and more, holding her growing monsters in her arms as she giggled feeling herself begin to pass 8'6 feet tall. "I'll let you go down there and bring her back down to size...so long as you promise you won't make me any smaller...haha….hahahaha!" Another growth spurt sent Laura’s sliding legs past behind them as they heard a chair get shoved aside in the kitchen beside them. “Ok. Please...Tiffany the house isn’t worth it…” - “That’s...not a yes...oh...mmm…” Her breasts began to fill out quickly, rapidly expanding all over her chest and arms as she hung them over his head. “Tiff! Let me...get through...argh!” Howard tugged on the doorknob, but it was no use, he was powerless against her new size, being held back by a single one of her arms as she continued growing through her last spurt to reach her final height. She looked down at him and her breasts, expanding past K cups as she cooed, giggling and pressing on the door harder, feeling her body growing taller and taller, as she passed 8’9. “Ooh...I didn’t expect to grow this much...mmm….yes...bigger.” She chanted again as her body only grew bigger, reaching 9 feet tall as her breasts passed massive L cups in size. She moved on him, starting to smother his smaller body with hers as she pressed up against him up against the door.  Her body smashed him up against it as she giggled repeating again, “Promise…?” She smiled tilting her head as he grunted and then sighed in response. “Fine, I promise.” - “Yay!” She let him go, catching him softly before he landed on the hardwood floor as she opened the door for him. “After you…” He shook his head and raced down the stairs as Tiffany looked over towards the kitchen and began to roll her eyes in response.

Howard was frantic, his hands moving quickly as he prepared the next formula, grabbing vials and tubes, different beakers in his wide arms, setting up his lab as fast as he could without breaking anything. Truth be told, he was nervous because he had never intended to create an antiserum, and had no clue really where to begin. His hands were calm, however, still and precise, besides the sweat pouring down his forehead as he measured chemicals and checked balances, he appeared to be quite focused on the task at hand. The shine from the glass vials and beakers surrounding him only grew brighter as he sparked the three bunsen burners within a few short seconds as he prepared the antidote mixture. He peered over to the end of the lab, seeing the tallest flowers near the middle of the room, bustling and full of life, the Goddesa flower had been blooming, spreading its pollen all over the plants surrounding it, he cleared his throat and approached looking at the other dandelions, field flowers, and other flora fully bloomed and boasting beautiful colors and aromas. He pulled out a thin pair of scissors, approaching a stalk connected to one of the larger budding petals, moving his shears towards it as he clenched on the tool stiffly. He felt resistance as the shears struggled to snap through the stalk of the plant, puzzled he tried again and felt his scissors begin to buckle. “What the…” A sudden snap sounded as his scissors popped out of his hands and onto the table, now in two pieces, jagged and edged apart. “Wow…” He mumbled looking back at the plant stalk seeing no visible cut marks, as he started to stroke his beard, looking back at the petals of the plant. He shrugged, still fascinated by the sheer resistance of the flower’s roots as he carefully plucked a single petal from it, watching the pink floating particles of the flower float around the beautiful white and pink petals. He made haste, avoiding any contact with the flower as he approached his station, moving the petals into a blending unit, adding clean white oil and other stabilizers as he pulsed it, still beading with sweat.

Upstairs the room had been shaking every now and then, Laura’s giantess body was starting to pass an entire story in height as she was passing 15 feet tall as her body trembled with intense growth surging into everything around her, the windows shook in the house as she adjusted her massive body in the large open room. “Nngh...It’s not...awhn...stopping.” laura mumbled to herself as she felt her fingers treading across the ceiling, watching her body bend more and more, buckling against the wall and the hardwood floor beneath her, making pounding noises above Howard’s head as he began to distill the antiserum into a large vial, adding the flower mixture to it as it bubbled up turning a bright orange. “Hmm. Looks like a reaction happened. We can try this one.” He mumbled to himself adding a liquid base and moving it into a large container and watching it boil into a more dense substance. Tiffany pouted, stepping over her long legs and into the kitchen space, crossing her arms between her two incredibly huge thighs as she looked over to her wet pussy with confidence, ignoring her gaze over her crotch and all the way up to her head that was now smushed up against the ceiling wall. “You always take everything too far Laura!” She shouted, starting to turn red with anger and embarrassment. “Tiff...nngh...this isn’t the time for that…” - “When is? Hmm? You giant slut!” - “Slut?! I don’t even get out! You’re the one fucking around with everyone’s boyfriends!” - “You just had to be the biggest fucking bitch didn’t you? You’re so selfish! Look at the house!” - “Shut the fuck up!” - “Make me!” - “Nngh! Oh my god! You’re such a bitch!” Laura reached over and snatched her up without any trouble as she fought back slamming her hands fruitlessly on her huge arms. Tiffany reeled in horror as she saw her hand wrap around her entire midsection with ease, not realizing just how much larger she was than her, she barely reached the height of her hips, she was over six feet taller than her in size. She lifted her up, pulling her beside her face as she smiled, holding her with a single hand as she toyed with her smaller body.

She leaned back pushing her entire body downwards as she slid down the wall and stretched her feet into the kitchen. “Hey! Careful! Ugh!” Tiffany shouted as she plunged her long legs past the countertop, knocking plates and other dishes on the floor, pushing past the sink, and resting her legs beside the fridge, the other blocking the way to the dining room. “You’re so noisy...just shut up....mmm...look at your body...you’re all filled out.” Her large hands moved across her body, feeling her thicker bits, grabbing her curves with her bigger size with ease, feeling her little weight on her fingers as she giggled. “You’re so cute now...haha…” - “Hey...what are you...nngh.” Tiffany squealed as she felt her big fingers pass by her aching pussy. “That’s...nngh...not fair…” She cooed as she began to tease her, moving it back and forth, holding her entire body with her other hand as she prodded harder, moving her thumbs over her breasts and shifting her body around teasing her roughly kneading her thick amazon body in her giant hands. She was relentlessly feeling her all over, like a full body massage, but from a busty giantess amazon. “Mmm...that’s better...now stay quiet and enjoy.” Laura giggled feeling horny, massaging her thick curvy body in her hands, watching her sister squirm and shoot seductive weary-eyed stares at her, wondering why she was giving her such great pleasure. “Ah...ah...ah...stop...I’m gonna...ah...ah...ah…” Tiffany was powerless against her towering strength, she began to stop resisting seeing this side of her sister gave her a strange feeling of happiness, she felt strange for a moment when she finally felt something new for the first time. “Aww...yeah just like that...I’ve never seen you like this.” Laura’s finger penetrated her wet pussy, thrusting in and out as she squealed in intense pleasure, sticking out her tongue and riding it as she shook, her pussy trembling being stretched out in the best way possible. Her eyes rolled back as she finally came hard, squirting and starting to feel the familiar feeling return to her as her body suddenly began growing rapidly. “Wait...what’s happening…” Her body shifted in size, rapidly growing and growing as she grew to 10 feet tall within seconds as her powerful orgasm finally faded. Her body burst outwards in her hands pushing them away from her growing form as she struggled to hold her, watching her hands begin to lose their grip around her expanding waist and chest. Tiffany was groggy, she fell forwards onto her sister’s larger body that began to shrink beside hers as she grew and grew, still growing into a larger and more powerful amazon, growing past 12 feet tall within a few short seconds. Laura grunted feeling her weight finally land onto her, moving her arms back around her, trying to hold her up as she lifted her sister onto her side, wrapping her arms around her, holding her close as she continued to moan softly in a state of fatigue. She felt her head lean up against her massive breasts softly holding her there as she moaned again softly, she blushed in response as she whispered. “It’s ok sis. I didn’t mean to hurt you earlier. I got carried away...again.” She giggled as she whispered back, still tired softly talking as she cleared her throat, still feeling itchy. “I know.” She squeezed her closer as her breasts pressed up against her as they both sighed.

Beneath them the burners finally clicked off as Howard retrieved the new anti-serum from the large beaker as he slowly poured it into a garden sprayer, filling it up to the top full of the now fluorescent orange serum. He sighed hearing the floorboards creaking upstairs, barely able to handle any more of the weight from his now two giantess amazon daughters. “Hope this works.” He sighed again and quickly moved to a cabinet near the doorway, opening it to reveal a large bug suit, he snatched it off the hook, getting dressed. He pulled the orange zipper up towards the top of the green onesie, as he heard a louder creak come from upstairs followed by giggling, and then a crash came from the dining room. Tiffany laughed as she felt the debris from a china cabinet shatter all over her foot as she slid it sideways feeling her legs crush more of the home decor. “Tiff…” - “Ugh. What I can barely fit in here anymore...nngh…” Tiffany’s body continued to increase in size as she coughed, feeling her throat itching as the residue continued to slowly drip growth serum down her mouth. Her legs treaded across the kitchen trying her best not to push over anything else as Laura pushed back at her, feeling her feet about to smash through the wall, trying her best to keep her thighs from smashing the tv and other furniture around her titanic body. “Ugh! Stop squirming Tiff!” - “I’m trying! Nngh...oh fuck…” Tiffany’s body surged pushing her away and to the side again and again until she finally started to match her size, reaching her single-story tall size of 15 feet tall now really pushing the space in the room to its maximum limits. “You’re still growing?! What the fuck!” Laura shouted, now getting upset as she smashed her breasts against hers, feeling her body twisting and turning as she pushed herself on top of her body, smashing her against the ground and rubble beneath her giant body. “Looks like I’m the bigger one again! Haha! Mmm...oh...yeah...I feel it again...sorry sis...ooh...yeah...mmm….fuck!” Tiffany’s body only grew more massive, passing 16 feet tall as she started to push her down deeper as the hardwood began to crack and finally start to dig inwards as they started to outweigh the floorboards. “Tiffany! Stop! We’re going to go through the floor!” - “Oh...god...you’re right…” Tiffany started to panic as she only grew more thick and curvaceous, she watched her breasts expanding bigger and bigger as they consumed the space between her sister and her own gigantic cleavage. Their incredible globes smashed up against each other, pushing against each other’s chests and Laura struggled to push against her sister’s new size, feeling her giant breasts pushing harder onto her face. Tiffany laughed maniacally as she leaned closer and grinned devilishly speaking softly but in an intimidating tone, “What are you going to do now...if I get carried away…?” Just as she started to laugh loudly feeling the floor buckle beneath them the door slammed open as Howard appeared suited up with the garden sprayer in hand.

“Dad?!” - “Howard?!” They both chimed in as he began spraying without any concern, he coated them in an orange hazy spray of serum, all over the furniture, destroyed table, walls, everything began to turn orange. They coughed as the spray began to cover them from head to toe, smothering them in the anti-serum as he stoically approached, coating their long legs all the way towards their chests and toward their arms all over. Their huge juicy breasts completely got coated dripping wet with orange oil, slathering all over their bodies. “Ugh! What the fuck!” - “How-ugh!” The girls began to feel woozy as they started to close their eyes and fall into a deep slumber. He stepped back watching the serum begin to take its effect, as he focused on them. They began to shift and change, shrinking in size as he sighed with a huge release of relief. “Oh thank god…” He said as he gulped seeing them shrink down a few inches at a time, slowly back down. He stepped back seeing the orange serum begin to flow its way towards his feet, moving back into the kitchen, peering at their legs sliding past his feet past his own, shaping back to a more manageable size. He smiled underneath his mask for a moment, until he remembered the promise he made, starting to suck his teeth, thinking of what would come next.
