Chapter 1: Gaining Assets

The classroom was quiet as the professor, Dr. Fitz continued his lecture about hormones and how the body uses them to facilitate growth, “All matter of beings exhibit growth when growing up and maturing through some kind of process...the interesting part is how those organisms and beings function in different environments and bodies. The physical characteristics of the female pituitary gland for example; it pumps hormones continuously into a female body, naturally of course,  through puberty that facilitates growth, so that obviously the cycle can continue…they can provide more for their children, feed them with larger breasts, attract more mates...” Justin sat fascinated as the crowd of students in the college classroom lab, was silent among a few coughs and shuffling of chairs. His messy brown hair laid plainly over his well chiseled head and jawline. His features were strong, but his age made him appear soft and gentle. “...but what if I told you that with modern science, those variables can be adjusted, if the proper external variables were designed to produce the same effect, really it could be recreated quite easily if given the proper formula…” Justin jotted down his notes and waited eagerly after class was up and confronted the professor. “Hey, Professor, you have a sec?” Justin spoke softly and cleared his throat. “Err...I suppose, what is it?” Professor Fitz wasn’t too tall, he stood in a standard science working man’s outfit at five foot ten. He had a lab coat on with a few pens stuffed away in his coat pocket, along with notes and crumbled pieces of paper loosely tucked away in his brown dress pant’s pockets. His eyes were sunken in from years of desk work and studying, he winced slightly. “Um...right...the lecture today, it was amazing, incredible really-” - “I don’t have time for small talk, sorry.” - “Oh! I’m so sorry, Professor, I’ll be brief. You mentioned certain variables and a formula... My girlfriend, Megan and I are really interested.” - “A new test subject...Hmm…meet me after sundown, eleven forty five, at this very spot.” - “O-ok! Thank you so much!” Justin instinctively reached in to grab his hand, but wasn’t given the same respect. “Eleven Forty-five. Don’t be late. Justin. And bring your...girlfriend.” The professor walked off as Justin stood there abashed at what just happened, he quickly took out his phone and texted Megan.

She was standing in the kitchen of her mom, Amanda’s two story home, it was a large kitchen space, with several chairs for entertaining guests, but it was pretty modest. Megan rolled her eyes as the familiar haunting sound of the stomping of feet coming down the stairs early in the morning as she sprung quickly to set up coffee before her step-sister would take over and make her demands. Megan was a short haired brunette with deep blue eyes. Her grey and black dotted top had ample room for cleavage, but unfortunately she didn’t have much to shoe off in the chest area. Megan was minuscule to say the least, she was a tiny girl standing at a meager four foot six but had decent B cup breasts for a girl so short, her thighs were thicker than most girls, but not to an extreme, mostly from her mother’s gene’s being so tall and voluptuous. Her mother Amanda, towered over her with long golden brown hair, and large C cup breasts in comparison to her height, her mother was tall, five foot nine and poor Megan's short height made her perspective eye level with the bottom of her mother's more than ample breasts. Ashley strode into the kitchen wearing nothing but her pajamas, her belly stuck out over two decent sized mounds of breasts tucked away in a silken halter top, her nipples were poking out of her slightly smaller than step-mom’s C cup breasts. Her apple-bottom butt nicely rode the slightly loose cotton pants she wore. Her hair was tied neatly into a ponytail with a scrunchie as she bounced into the kitchen for breakfast. She moved up to her step-sister, Megan and bumped her aside with a thrust of her hip sideways. “Ugh! What the fuck!” shouted Megan, but shortly after her step-sister towered over her a whole eighteen inches taller, a foot and a half taller her body cast a light shadow over hers as her big hands began to fondle Megan’s body. Megan was craning her head trying to force her vision past her belly button and boobs as she grabbed her sister’s right nipple and started twisting it. “Ow! Stop!” - “Haha...shorty...little tiny shrimp…” - “Quit it!” Ashley toyed with her nipple as she felt it slowly get hard and engorged. She let go as her shirt settled looking down at her little boobs and her tender erect right nipple. “You might as well, pinch the other one...at least then it will match...haha…” Ashley smirked and when Megan wasn’t looking flicked her left nipple, but this time Megan felt slightly turned on and let out a soft moan. Ashley blushed and started to blend a smoothie for breakfast brushing off whatever happened as Megan tried to contain herself.

Things settled down a bit, but Megan was fuming watching her step-sister inside someone else’s house felt like shit, she had no authority over anything and always felt like a little ant inside a big home. There was nothing she could do about it either, she sighed and took her cup of coffee without milk or sugar and sat down in the farthest chair in the back, as was instructed by Amanda, a few nights prior to the new sleeping and bedding arrangement made by Justin’s father Matthew Brooks, a military sergeant currently deployed out of the states. Justin was left really to take care of the house, unfortunately his new remarried wife, Amanda; Megan’s mother, had taken all that authority from him a few months before he departed. The house was now Amanda’s domain, but she worked a lot of long hours, making Justin the next one in line, however it wasn’t so easy, Ashley always had some kind of demands to make or authority to possess over them, resulting in her bullying them day in and out.

Megan’s phone buzzed as she reached into her pocket apathetically and keyed in her code, 2342, as it clicked open a text from Justin popped up; “11:45, Lab 203 in the Parker Building, meet me there.” Megan’s face twisted in a knot as she blushed and then started to turn white thinking of the late hours and what he was implying. She panicked and sipped some coffee and almost wretched at it’s bitter flavor. Her fingers rapidly paced over her phone’s keyboard; “WTF No way.” The texts came back and forth quickly as her mood slowly changed from worry to being really horny. Her throat started to feel dry as she twitched a bit after reading the words; “Growth Serum”. And responded with; “Ok, but nothing weird.” - “You won’t regret it! I promise. 11:45. He said not to be late.” The conversation was just ending as Amanda entered the room, her golden brown hair was accented by a heavy layer of makeup, but nothing tasteless. She feathered her hair between her finely dressed up hands and delicate nails as she popped the fridge open and grabbed a piece of toast and looked over to the other two, “Hello?” - “Hey Amanda.” - “Morning Mom.” - “Ugh. Don’t say that, I’m not quite there yet with you two haha…” - “Oh...sorry…” Megan blushed now, really embarrassed. She quickly dropped another piece of toast into the toaster and moved towards Megan leaning in and giving her a kiss on the head followed by a smile. “Hey, little cutie, you’re going to have an amazing day today. Eat your breakfast.” - “Ok…” Megan was blushing even harder now, but happy as she waited for the toast to pop. She heard the ding as Amanda grabbed it and rushed out the door, “I’m late! Gotta run!” Megan stretched as she went to get up out of her chair, only to be greeted with Ashley’s ass in her face. She slowly bent over pushing her butt into her face as she plucked the toast out of the toaster. “Oops! Sorry...oh..last one...oh well!” as she straightened herself out and spun around, she tossed the leftover bag at her as it slowly drifted in her lap. "Get another bag after school little twerp, multigrain and make sure it's the exact same brand!" She sat there as the plastic bag slowly fell into her lap as Ashley laughed and walked off getting ready for her early morning swim class training. She stomped upstairs and slammed the door, as Justin was still at the campus eagerly awaiting for night to fall and for her girlfriend to grow. She tossed the covers over herself and started the cry, the only thing keeping her from really breaking down was the thought of Justin as she started to cheer herself up, "That fucking bitch! UGH!" Megan punched her pillow, grabbing it and screaming into it loudly. "I'm going to rub it in her dumb bimbo face, that fucking slut is going to regret bullying me when I get my hands on that growth serum…" Megan started to play with herself, toying with her erect nipples as the adrenaline coursed through her, "I can't wait to grow bigger…" She grinned and laid back, letting loose a long sigh.

The dark night ambiance was only amplified by the lamps surrounding the foggy college campus grounds, GigaU. Justin was posted up by the door with his phone slightly dimmed, he pressed the side of the device watching the sound slowly go from max volume to vibrate and finally went silent as he obsessively watched his phone until the light went dim. Then suddenly a flash, a text, “Go inside. <3” The door opened as Justin was pulled in by Megan. The room was dimmer than usual and a small light on the professor’s desk was lit dimly. Fitz was sitting on his desk with a box at his side as he entered he whispered, “Lock the door.” - “This is so exciting!” - “Shh…” Fitz shushed her, as she blushed again feeling like she was once again speaking out of turn. “Hey...Professor.” - “Hey Justin. You didn’t tell me you were sleeping with such a young girl…” - “Sleeping...I uh…” the two went red as a streetlight as their hearts began to pound rapidly. The professor waited for a moment and then smiled, “She’s perfect for the test. You really make a good first impression, remarkable.” - “Oh...I...thank you.” - “Well that's enough introductions...” - “Oh...um…” - “Let’s begin shall we?” - “Begin what?” - “The growth? That’s why you came here...didn’t you?” - “Oh my god...is this real? I’m kind of sleepy. Can you pinch me Justin?” Justin reflexively pinched Megan’s arm, “Ow.” - “Sorry…” - “Fuck...this is real.” Megan stared up at Justin with gleaming eyes, she smiled and craned her head all the way up and pouted, Justin was puzzled, "Whats up…?" - "Just taking one last look…" The professor smiled again and responded, “Very much so, very exciting, come here won’t you?” - she nodded and thought to herself, “I'm ready, time to get big…" Megan started moving farther away from Justin as his touch faded from her she approached. 

The professor took out some research equipment from a small discreet black plastic box, inside three vials of white cloudy liquid. Pulling a larger vial from the box he handed it to Megan and ushered her to drink it. “Now this is a double dosage of the serum, I think she’s so underdeveloped she needs a bit of a boost compared to an average girl of her age.” Her eyes widened as she gulped and put the vial close to her lips and started drinking it down. It smelled faintly sweet, and was slightly thick, as it touched her lips they began to tingle and become softer. Justin looked a bit tense, “Are you...sure a double dosage is a good idea?” Megan gagged a bit as her eyes started to tear up continuing to suck down more and more of the creamy growth formula. Fitz guffawed, “You want results...don’t you?” - “Yeah...but…” - “I should mention the effects are going to be delayed, maybe you’ll wake up to a suprise, maybe you won’t. Just in case, take this with you, and administer a second normal dosage, 10ml within 24 hours, and another each day until you feel good about your size. Don’t have any funny business either, ok? At least for a day or two. If she gets frisky, please hesitate to throw her a bone haha…” She blushed and took a moment to breathe, “Mmm..It tastes like vanilla...mmm gulp gulp gulp.” Megan continued drinking the vial down until nothing was left, she felt the last of the growth serum trickle down her throat and then burped quietly and smiled. She hugged the professor and looked up at him with a cooing sweet as honey tone, “Thank you!” - “You’re welcome, just remember me when you’re a supermodel and follow my directions, I wrote them down on a note at the bottom.” - “I’ll document my findings…” Justin said methodically as he placed the box back into his backpack. “We should head home.” - “Right.” - “Tell your mom, you stayed late with me in the lab, my number is on a separate note in there, give it to her please.” - “Ok. Have a goodnight Professor.” - “Bye!” Megan was brimming with joy as the two left the campus and got back into Justin’s car. 

The two sat there for a moment taking in all the adrenaline of the night. Justin sighed and looked over to Megan, “I'm sorry…” - “For what? Are you crazy? If this serum works I’m going to be so hot.” Megan adjusted her top and tried to act sexy, but she wasn’t filled out really and didn’t appear different at all. “Not that...I said you were my girlfriend...and i don't think Fitz would have given us some of the growth serum if not for that." - “...” A long pause was felt between them for a second until Megan softly spoke; “What if...I was?” - “You...like me?” - “...yeah…” The two sat there still for a second as Megan’s heart was beating out of her chest, she started to sweat as she felt warm all over. Her body began to tingle as she felt a strange itching sensation around her crotch. “I...feel something…” she panted softly as her heart began beating even faster. “Are you okay…?” - “I don’t know...I feel really warm…” her panting became feverish as Justin panicked watching her unofficial girlfriend burn up with what looked like to be a bad fever. She jostled for a moment as her pants became tight and her shirt started to constrict. Justin held his hand over her forehead, she was burning up and starting to sweat, she latched onto his hand and started kissing it, becoming more seductive with each peck.

Her soft nipples began to harder and get erect again, her blouse was straining a bit as it made room for her growing body, it was undeniable now, the growth serum was working. Her body pulsed as she bounced in her seat, growing an inch to four foot seven. Justin gulped and comforted her, “You’re growing...I can see it…” - “Mmm...yeah…?” Megan’s body pulsed again this time her breasts grew a cup size, filling out her bra as her nipples tensed up and grew even larger in size, starting to get red and erect underneath her top. “Oh...f-fuck...Oh…” her voice was fluttering as her thighs began to thicken and her legs grew longer and longer as she slowly stretched upwards growing two more inches to four foot nine. Followed after her hips and ass started inflating becoming larger and more luscious. Justin watched her head raise a few inches closer to his as her ass bubbled out against the fabric of the seat beneath her slowly straining as her leggings slowly started to rip. “I’m growing...so fast...oh fuck...oh my god...I’m so horny...Justin...please…” - “The professor he said…” - " Oh fuck me Justin! Please I need you so bad right now...ugh" - "I can't ruin the experiment by adding extra variables…" -“Oh...I feel it in my tits...again...oh fuck…” She ignored him, feeling her breasts begin overfilling her top, they grew bigger and bigger, and larger, filling with hormonal milk. She soon passed both her older counterparts, growing into big jiggling melons, now two double D cup breasts struggled to be contained inside her top as she tried to readjust her shoulder straps now falling down every now and then. “Look at these...holy shit!” she shouted, smiling widely. She blushed hard and seductively said, “Time for the boyfriend test...drive us home...sexy...haha” 

Justin gulped and pressed down on the gas without releasing the parking brake, a loud revving of the engine was accompanied by another bounce of her chest. Megan took off her top letting her two moderate boobs bounce on her bare body, covered in sweat and slightly red from arousal. The engine roared as it remained in park, Megan felt the vibration coarse through the vehicle as she started to get wet. “Whoa..easy tiger...take off the break first…” she giggled and tempted him again as she started toying with her nipples feeling them tense with pleasure sending waves over her body as she felt her skin stretch finally starting to grow bigger. Her leggings tore open around her thighs as they grew wider and more voluptuous, she got bigger growing faster three more inches now five feet tall. Her vagina was begging to be touched, at this point her pussy was so juicy and wet her panties were entirely soaked through her torn leggings. “I can’t take it anymore...ugh I’m sorry Justin...awn...I need it.” - “Megan don’t…” - “Mmm...fuck...please Justin...you don’t want me to grow...you don't want to make me cum...you should be a good boyfriend...watch me grow...bigger...and bigger...and even bigger…”

She reached down pleasuring herself with each pass over her vagina and clit she chanted on and on, "Mmm..bigger...bigger…" She felt her pussy tremble as the sensations overwhelmed her sending her into a growth fueled orgasm. “Fuck! I’m gonna cum!” Her body tensed up again as she grew again, taller and even bigger, shredding out of her top, her leggings barely clinging onto her new thicker and juicer body, she grew bigger and bigger in a huge spurt, shooting up another four inches to five foot four. Justin was speechless as he kept driving down the road getting close to their shared house, rocking an insane boner he could barely think and pay attention to the road as the car swerved onto the median for a moment. He gasped and caught his breath as he kept glancing over at her watching her head and lips move farther and farther to the roof of the sedan as she grew taller. From his perspective she was at his shoulders, then under his chin and now he looked forward at her lips at his eye level as she grew another four inches to five foot eight! “We’re going to have to sneak in the back haha...oh my god...what am I going to wear...why am I still...so...horny...mmm...oh fuck…” - “Megan...slow down…you need to stop setting off your endorphins.” - “Mmm...I'm already taller than you I think...I can feel something inside me...making me want to get...bigger...feels so good...my pussy is so fucking wet Justin...I can’t wait for you to...oh fuck...Justin...I’m gonna come again...oh fuck...here it comes again!” 

Her body tightened as she grew even bigger in one massive growth spurt, growing several inches taller as her body blossomed again growing thicker and more voluptuous. Her bra snapped as her shirt stretched under her slipping bra as it overflowed with big juicy breasts. Her tits grew larger again until they were huge E cups on her chest as her body finally stopped growing at five foot ten, “Christ...Megan you’re almost as big as Amanda!” - “Actually...I think I’m bigger...” She held her big melon sized breasts in each hand trying her best not to play with herself again, feeling their weight and jiggle. “Yeah...mmm...and these are so much bigger!” Justin grabbed his rock hard dick, and gripped it biting his lip. “Damn...you look really good...fuck Megan…Oh shit...Hey we’re pulling up now, act cool if everyone wakes up.” - “Oh...just wait until I get you into that bed…” The car slowly pulled in the driveway as she leaned into him and moved in to kiss. Her lips felt fuller and more bouncy as Justin laid on his skills, starting to french kiss her, Megan started to blush again, her vagina tensed up and pulsed as she started to moan while growing another inch, now five foot eleven. Just felt his hold on her lips wane as she moved upwards snapping her lips off of his and growing taller. “Mmm...” - “More…?” - “Yeah…I’m still getting taller...” she giggled and thought to herself; “How big am I going to get…bigger than...her?” she blushed again feeling her wet pussy aching for her boyfriend's cock. - “Hey...let’s get inside. Try not to make any noise, ok?” Megan giggled now noticing she was looking way over his head now, she was looking forward having to crane her head a half a foot down to see her now small boyfriend. “You look so cute...haha...look at you…” Megan grabbed his arms and chest, running her fingers down his body, and felt her larger hands encompass them. Justin leaned in and kissed her again, feeling himself have to strain to reach her side of the car and new height. She smirked noticing their substantial height difference now, she was over half a foot taller than him now, and was much larger in size. Justin felt belittled and pushed her hands away and pouted, “Are you listening?” - “Aww...little Justin...I’m sorry…” - “I’m not little! You’re just bigger...now...and...taller…and...” Justin’s eyes panned slowly over her huge perky breasts as his mood and attitude slowly drifted away, they hung like two gorgeous cantaloupes, eager to be squeezed. - “Aww...oh my god...you’re so adorable, lets get inside.” 

The two of them turned towards the house as the lights of the sedan went dim, Justin looked back as Megan started to struggle with her seat belt, feeling her ass start to bulge and grow larger and more pronounced. He watched his dick jerk in his jeans as her butt grew and grew larger until it was a big bubbly mess of two bouncy butt cheeks, her leggings tore open revealing her tight asshole puckering and dripping messy vagina as she bent over and exited the car. Justin tried to contain himself, but he could feel his dick oozing out pre-cum as she lifted her wet pussy off the passenger side seat and walked seductively beside him, his eyes met with her neck now, close to her huge line of ridiculous cleavage. “Let’s go shorty!” - “Shh…” - “Oh...sorry…” she giggled as he watched her tits jiggle and ass bounce with each step towards the back door of the house. The two opened the door and raced upstairs as the hallway split, Megan leaned in for a kiss goodnight and whispered, “I can’t wait for tomorrow...to grow even bigger…” - “Night Megan.” he kissed her, but she was more forceful this time and grabbed his dick whispering again, “Oh...get in here I was playing hard to get.” she grabbed him and tossed him into her room and closed the door quietly.

Justin was bamboozled, he was having the night of his dreams, watching his crush grow bigger and sexier before his eyes as she started to strip in front of him. He watched the tight pieces of fabric tightly bound on her thick curvaceous frame, delicately being torn off with each tug of her now bigger and stronger arms. Justin followed suit as he felt his boner a bit sticky from his own cum finally get released from his pants as he unbuttoned them and tossed them to the floor. Megan’s eyes widened seeing Justin’s rock hard throbbing member pulse almost painfully red from so much teasing. “Oh babe...you’re so hard...awhn.” She fell to the floor on her knees and grabbed him by his hips, shoving him onto the bed. She smirked and lowered herself down to his hard cock and gave it a lick, feeling it throb and twitch. She proceeded to give him the best head of his life, she let loose her wild tongue over his aching dick, feeling her pussy tingle as her big juicy ass bounced on the floor with each sucking motion. Unbeknownst to them the door creaked open, Ashley stood there looking in, her mouth dropped as envy began to build at an alarming rate. Justin writhed in pleasure, “Ugh...you’re so much bigger now...” - “Mmph...I can’t wait to drink more tomorrow...I’m gonna outgrow that bitch sister of yours.” - “Mmm...fuck...you sure you want to get even bigger?” - “Mmph! Aah...hah...yeah...actually I was thinking...maybe I could take... another double dosage?” - “Uh...I don’t know about that-- Ugh!” Megan started to deep throat his dick, fitting it entirely in her soft supple throat as he felt himself brimming with pleasure, his cock erupted in her mouth as she drained him dry. “Mmm....it will be twice as fun...pretty please...” - “Fuck...Megan...fine.” - “Yay! You’re the best boyfriend ever.” - “Mhm.” Justin laid back onto the bed feeling exhausted after getting such an incredible head. Megan joined him, beside her he felt small now, her big beautiful breasts rested gently next to his head as he slowly drifted off into slumber.

Her eyes opened as the sun was barely starting to rise early in the morning, Megan always got up earlier than her boyfriend, Justin. She looked at him for a moment seeing him calmly contemplative face usher out a few soft long breaths as he continued to deeply sleep off the long late night. She felt warm and cuddly, she felt a twinge of pleasure escape her mouth with a soft moan, when she looked down to see her body. She smiled and quietly left bed and headed to the bathroom, entering it looking at herself in the mirror something felt off, her eye level was near the four dim bulbs on the bathroom dresser. She was always a couple inches, maybe even a half foot away from them. “Did I get bigger overnight?” She felt herself up and spun herself around, her ass was bulging and even bigger than before, she bent over and slapped it once feeling a tidal wave of ripples cascade over it, “Oh...my fucking god...I’m like Nikki Minaj what the fuck...this ass is huge.” she cooed at herself and made seductive faces and stances in the mirror, she put a hand underneath her breasts, they felt fuller, and her nipples were definitely bigger, what she didn’t realize is that she was now standing at a statuesque six foot three now, meaning she grew four inches overnight! 

She stepped into the shower and felt the warm water hit her messy cum stained body, as she started to feel relaxed. Her warm silken white skin soon started to soften from the warm running water from the shower head. She smiled feeling herself up glancing at the shower head that was much easier to grab today, starting to have a flashback from when she had to climb the side of the tub to be able to grab it. She continued moistened her body all over, spreading her legs and blasting the water jet into her pussy felt good. "Oh fuck...Im so big now, God I can't wait until Ashley sees me...awhn…" she though to herself moaning softly. "...and Justin so fucking cute oh my god...I drained his cock so good last night he couldn't even think...hahahaha!" Megan felt a pulse through her body, "Awhn…" she moaned again, louder this time. She bit her lip and grabbed the soap and started washing herself down, sliding effortlessly over each luscious sopping wet curve of her sultry adult body. Her soapy hands met her two large breasts, she jiggled them playfully, up and down, then side to side, starting to pinch her nipples between repetitive massaging. Her two succulent melons slipped and slid over her fingers gently riding against her now engorged nipples. The sensation grew stronger, now reaching for her pussy moving the shower head back into the holder. She felt warm again as her bouncy and bubbly body started to tingle all over. She was experiencing the final wave of growth from her double dosage of the serum. Her feet strode along the tiled floor, feeling the friction ease from the dripping water beneath her, as her head rose higher. She opened her eyes for a moment to glance at her surroundings this time watching her body slowly take up more space around her, this time growing exponentially, her entire body grew at once, making her taller and bigger. First she slowly inched larger and larger growing to six foot four, another inch. Her fingers dug into her wet vagina, back and forth she moaned loudly feeling the sensation only build stronger. Her eyes slowly met with the curtain pole for the shower as she grew taller, inching taller to six foot five. She continued growing taller and taller, her head raised over the long shower curtain as her head slowly peeked over it. "Oh my god! Its happening again...fuck I'm all super horny again...mmm so horny...awhn…" she groaned as she climaxed. Her body trembled finally settling in at her final height of six foot seven, as she fell to the wall of the shower, she felt her boobs pressed up against the wet tile and laughed. "I'm definitely bigger now...holy fucking hell, I can't wait until Justin and Ashley see me."

The morning sun broke the curtains as the light poured into Justin’s messy bedroom, he looked around noticing Megan’s shredded clothes and stained panties on the floor. He heard the shower going and decided to head downstairs and make himself coffee, he felt especially drowsy this morning after yesterday’s insane dream-like experience. He popped on jeans and felt a lump in the side pocket, a small box with five vials inside. “Guess it wasn’t a dream...fucking hell...well I better do what she tells me or else she’ll break my dick or something...that’s kinda hot...fuck.” he shrugged and took two vials and headed downstairs. He did his normal routine, he made himself and everyone else a large pot of extra strong coffee, he saw a note on the counter, “Sorry had to run out early! I got bagels and fresh fruit! <3 Love Amanda.”  He saw the said fresh fruit by the kitchen counter and saw a blender nearby, he thought to himself, “I’ll surprise her and put in it a breakfast shake. Yeah that will be fun.” He chopped a few strawberries and a banana, and finished off the beautiful mixture with some milk. 

He looked outside seeing the birds chirp and trees sway side to side and took a moment to appreciate his life and reached into his jeans and plucked the two vials out and poured them into the blender. With a few pulses of the machine the growth shake was finished, he poured it into a glass and raised it up looking at it for a second in the reflection of the sliding door. Suddenly a hand plucked it from his and he heard a deep breath and then followed by some slurping. “Oh Meg! I hope you like it. I added some fresh-- Ashley?!” - “Hey Nerd. This stuff tastes fucking fantastic what did you put in it? Mmm...gulp gulp gulp…” Ashley towered over him as usual and started to pour the entire glass down her throat, with several long gulps, she felt tugging on her arm from Justin, “Hey! That was supposed to be for Megan!” - “Burp! Oops sorry...damn that was great though, thanks short stuff.” Justin was pale as a ghost, he was crushed, he knew that an already highly developed body absorbing the growth serum could have some potentially disastrous results. Ashley started to smile devilishly, “What’s wrong…?” - “That stuff...it’s really not meant for you...it’s uh…” - “What… don't tell me, it's full of human growth hormone serum? Yeah I heard you talking about it with your little girlfriend last night.” - “What...you...were watching us?” - “Mmm...yeah and now...you just gave me a double dosage of the growth formula.” - “Oh...fuck.” 

Megan was never this happy before, she bounced out of the shower and grabbed the towel, which barely covered her huge juicy silken body. She dried herself off with a few groans readjusting herself to her new size and height and headed out the door. She rustled through her clothes trying to find a single piece of clothes that would fit, but it was no use, she grabbed some baggy sweat pants that came up to her shins and a collared shirt and buttoned the bottom few buttons. She tried her best to stop her massive now F cup breasts from spilling out of her clothes as she raced down the stairs to find Ashley in the kitchen blocking Justin from sight. “Good morning everyone!” Megan said as she strolled into the kitchen triumphantly. 

Ashley and Justin were absolutely stunned, Megan’s new beautiful body bounced with a luscious and seductive lilt. She moved in on Ashley and looked down at her for the first time, she was speechless, “Hey Ashley, how are you? Oh you like the new me? I do too haha…look at these things!” - “T-they’re huge.” Ashley stammered feeling her massive breasts being shoved into her face. “Megan I’m so sorry…” Justin moved around Ashley and closer to Megan hugging her body, now realizing she had grown even larger, “Holy fuck! You’re fucking huge! What the hell happened?!” Ashley tried to play it up, acting dramatic, Megan bought into it, but Justin was seriously getting nervous looking at Ashley’s nipples starting to get hard as her cheeks and face started to get red and blush, the formula was starting to affect her hormones and the growth serum was starting to pump through her system.  - “Oh yeah! Look at my tits...mmm babe…” As Megan continued to tease and prod Justin, when Ashley started to feel warm. 

Her tank top felt tight along with her jeans, they began to constrict as her thighs, legs, and feet started growing. First she only felt an inch of height growth, now six foot one, from her legs stretching, but the hormones quickly began to build in her chest as Megan leaned way down to Justin's level for a morning kiss, her body flooded with endorphins. Ashley started panting hard as her hands reached for sensitive regions on her body, she caressed herself softly, starting to moan and blush harder, still being ignored by the two lovebirds. The feeling came on stronger, when Ashley’s pink panties beneath her nightgown started to get wet, her legs quivered as she stuck her tongue out feeling erotic. Her pussy clenched again and again as her heart started pounding faster, Ashley began to softly moan as her pussy began to leak cum, now dripping down her growing thighs. She felt something odd, but soon realized that her clit had grown double in size and was extremely sensitive making herself slowly orgasm. Justin turned to Megan and spoke nervously, “Ashley are you ok?” - “Woah...Ash! Are you alright?” Megan quickly came to her aid and softly touched her shoulder, this only sent waves of pleasure through Ashley's body as she suddenly started to orgasm. She fell over onto Megan, who caught her feeling her hot body on hers, sprawled all over her bigger frame. “I feel...good…” Megan felt Ashley’s weight start to increase as she gained mass and began to grow bigger and bigger in her arms. Ashley’s body really started expanding in size, quite rapidly several inches at once, she shot up to six foot five in a matter of seconds. "Ashley! You're growing!" - "Ugh...this is...all your fault...little man...hah...haha…" Ashley started to mumble and whisper as she grew past Megan’s height of six foot seven and started to french kiss her, “Mmm...you got big...but I’m bigger...and I’m going to get even bigger…” 

Justin didn’t know what to do, he was getting really turned on at the sight of his now amazon girlfriend kissing his even larger growing sister. Megan started to get really horny and gave in, realizing there was no fighting the hormones within her and began to feel warm. She reached down and got a handful of her step-sister’s ass, and felt it growing, she kept on her with her tongue, intertwining and moaning between lips connecting, she felt her butt growing in her hands. Her hands filled with her flesh as she watched her hips grow wider and more shapely. Her nemesis was busting out in the most booty-full way possible as her ass bulged outwards, quickly contesting, and then surpassing hers in size, bounce, and juiciness, it was insane, her ass was goddess like, and unearthly. Her heavenly ass bounced and jiggled more than no other, as her hips got wider and more shapely, soon lining up and then overtaking Megan’s as her body grew larger and ridiculously voluptuous.

Megan’s body tensed up as her vagina got wet, as she grew with Ashley trying to contest her growth, another inch to six foot eight as she passed her head and tried to shove her tits in her face. Her body surged with pleasure, feeling Ashley’s body grow bigger in her hands, just made Megan envision herself growing bigger and towering over her. “I’m bigger, stop trying to outgrow me you bitch!” - “Mmm..you busty little slut...your boyfriend tried to make you bigger, but I took your double dosage, there’s no way you’re going to catch up to me...hahahaha!” With that Ashley’s body bulged outwards all over, growing several inches again and again, increasing in speed and size, until she was six foot eleven, she toppled Megan over on the kitchen floor and spread her hands out overpowering her with her size. “Ugh! You cow get off me!” she screamed as her breasts grew larger on top of her, they ballooned outwards and started to weigh her down, increasing cup size after cup size. Her beautiful F cup breasts were soon dwarfed by Ashley’s two K cup monsters as her body pulsed with growth hormones again as she surged in height several inches again over seven feet tall, she was getting massive. Megan's vision was slowly being blocked by her flesh and body watching her head slowly move further away from her vision over her view, met with two gigantic breasts slowly becoming filled with hormonal milk filling up larger and larger, growing even bigger by the minute. “You fucking...mmph...mmph!” Ashley bounced upwards a few more inches, growing taller to a colossal seven foot seven, finally her breasts were large enough to engulf most of her head, “What’s that...I can’t hear you over my massive titties!” 

Justin panicked and ran upstairs looking for the box, while Megan struggled, she gasped for air a few times and was running out of options. She looked at her huge breasts that were keeping her trapped underneath her, and felt that both her nipples were lactating, she fidgeted around until Ashley moaned and let loose a long sigh moving her nipple towards Megan’s mouth, “I’m so...big...so much bigger than you...little shorty...hah...haha...oh...fuck I’m so goddamn horny…” Ashley took a hand off of her and plunged it into her bottom gown, and began rubbing her pussy. She moaned letting loose hot streaking breaths on Megan as she felt her hot breath she started getting horny. “Mmph...I can’t breathe!” - “I need a man...where did your stupid boyfriend go...I need his cock inside me.” - “You fucking bitch!” Megan pounded on her ass trying to get her to release her, but her punches felt like a child’s fists, they didn’t even bruise her skin. Ashley felt a kick of growth again as her body grew another four inches to seven foot eleven, now completely starting to dwarf her busty step-sister. “I’m sorry what did you say?” She applied more force this time as Megan whined she felt her body start to really wane with her newfound strength. “Apologize, now.” - “Ugh...ow...fuck you!” - “Show some respect!” She lifted her body up off of her, met with a massive release of oxygen she gasped for air, only to be met by a pair of huge hands grabbing her and lifting her off the floor. “Put me down! Holy shit you’re gigantic!” - “I said apologize.” - “I’m...sorry.” Ashley got wet as her eyes rolled back feeling her authority finally met by her unrealistic standards of power, she surged upwards growing and growing, Megan watched in horror as her hands slowly began to envelop her lower torso, she watched her perspective shrink from her neck down to her chest, past her cleavage until she was staring above her two very erect and dripping milky nipples. She grew and grew until her head bumped the ceiling,  growing past eight feet tall now towering over everything and everyone in the kitchen, that was starting to feel smaller by the second.. “Ow! Holy fuck! I’m getting so huge!” - “Put me down!” - “Ok ok...I’m sorry.” She planted her down and then sat on her huge ass, she stretched her now eight foot four body out across the kitchen, feeling horny and luscious, she felt her now huge pillow-soft lips and big juicy breasts swaying side to side.

Megan was distraught she was watching Ashley stroke her engorged clit and pussy, orgasming every few minutes, while she panicked frozen standing still. Ashley didn’t stop growing either, she surged upwards reaching a peak of her orgasm, spilling cum over the floor listening to the squeak of her wet ass stretch and grow larger over the kitchen tiles. Her body lengthened and kept growing larger and fuller until she filled most of the room. She had a few large growth spurts through the process resulting in over a foot of height growth. Ashley’s foot pushed against Megan in one last large growth spurt, throwing her back a few feet, noticing Ashley now nine feet and two inches tall, it seemed the growth spurts had stopped for now. Ashley groaned like some animal in heat as she slapped her wet pussy a few times watching Megan at the verge of tears. “Christ...that was incredible...I gotta hand it to your nerd boyfriend, this is some good stuff.” - “You weren’t supposed to drink that! I’m on a clinical trial for a growth hormone!” Megan lied, but it was her only excuse for purposefully abusing the growth serum and wanting to take so much of it at once. - “Trial huh? I guess I’m in it now too.” she grinned devilishly and for a moment her clit twitched thinking about growing even larger than her already titanic body already was, she lifted herself up a bit, moving on all fours towards the hallway, she threw Megan back not realizing her strength into the trashcan and fridge, knocking it over and spilling it all over. “Augh! Euch! What the fuck!” - “Sorry! Sorry! I’m so huge! I didn’t realize how big I am hah...haha...well you should take out the trash anyways...stinky...haha…” she laughed bellowing outwards across the house, moving to the stairwell and front door, Megan watched her humongous ass get close to the hallway entrance and then start to bulge and jiggle. “Oh please...god no...no more…” - “Is something going on back there…?” Ashley called out blushing when suddenly her vagina started leaking a thin trail of cum, she made an ahegao face, sticking her tongue out and rolling her eyes back as she slowly came, as her ass bubbled out growing larger, slowly taking up so much hallway space that it begins to wedge between the walls. “Awhn...fuck...my ass is getting bigger, hey step-sis I’m stuck!” - “I’m kinda busy right now!” Megan was furious and covered in sticky bits of banana peels and strawberry rinds, she dusted herself off and gazed at her gigantic ass as she surged larger, cracking the walls around her revealing the broken drywall. “Ashley! You’re getting too big for the house!” - “Ugh! I know...isn’t it fucking hot?!” - “Ashley get out of the house, you’re going to destroy everything!” Megan panicked and ran out the back door, but not before bumping her head on the door frame and falling onto the floor. 

She rubbed her head, a massive bruise laid there now as she started to cry, nothing was going right and the day was ruined in her eyes. Justin called out from the backyard crawling down a ladder, “Hey Megan over here!” - “Justin?” Megan ran out back, seeing Justin with the box in hand, “Here, take one...woah woah woah, I said just one!” Megan snatched the box, and unplugged the first vial and chugged it down, then the next. She grabbed the final vial and burped a bit, then smiled seductively down at Justin, his face was full of fear and envy, his eye level was at her gorgeous rock hard red nipples, she lifted his face up to see her two breasts blocking most of her face, she smiled through them regardless and softly said, “I’m about to bust out all over my little shorty.” - “...C-can’t wait…” - “I’m already feeling the first two...mmm...but here goes another...mmph! Gulp gulp gulp…” Megan sucked down the last of the final three vials of formula taking a triple dosage at once. At first she dropped to her knees, sending a gust of air around her felt by Justin, now abashed at the results of the growth serum reaching its peak. Megan’s body in one huge spurt shot up six inches at once, a massive growth spurt of half a foot growing taller and taller, and larger, upwards reaching seven foot two in a matter of seconds. “Oh FUCK! It’s so strong this time...hnng! Ugh!” Her body ached and trembled feeling her breasts fill up and up with milk she clenched her teeth and twisted her tongue as her breasts grew several cup sizes at once, growing bigger and bigger in her hands. They slowly began to feel like two large bags in her hands, and the larger they grew the softer and more bouncy and luscious they became. Her breasts shot out milk over onto the wet morning grass, “Oh f-fuck...Christ...oh...fuck…” - “Megan! Are you ok?” - “N-never...been...better...hah…” her panting became stronger and more rapid as her body pulse again as her already titanic ass began to overflow her back feet and legs. Her ass became amazonian in side and width as her hips grew to a ridiculous curvaceous size passing far past seventy inches in width. “Ugh...finally I’m growing into...a giantess…” - “Is that what you wanted all along…?” - “Fuck YES! I want to grow even bigger...and bigger...and bigger...mmm...more...so much growth serum...inside me...I can feel it pumping...awhn...and pumping into my body...mmm...fuck!” Megan’s body grew wider and larger again passing eight feet quickly and larger and larger she grew.

A massive thud and crash, followed by a gust of dust came from the frost of the house, circling the front. A titanic nine foot ten Ashley emerged, her breasts like two watermelons held up by her two crossed arms. She looked over the house by the driveway as Megan continued growing. Ashley moved to the backyard to meet her and Justin, “Well...well...what do we have here…” She motioned towards Justin and tried to pick him up, but was stopped by Megan’s arms. “Get away from him!” - “What are you going to do about it.... you little...fucking...slut?” - “You BITCH!” she screamed trying to push her back with a bit of serious force. Ashley was gigantic and she was barely up to her shoulders as they started to fight, she pushed her back, and then suddenly noticed a massive shift in her perspective as Megan shot up again another four inches to eight foot five. Megan’s head began to peek over her shoulders as her body surged with growth. “How are you still growing? What the fuck!” - “Remember...when you said...you took my double dosage today....well I just took three…haha...hahahaha…” Megan saw the look in Ashley’s face as she reeled back a bit loosening her grip on her as she bounced again, growing bigger and bigger, this time passing eight foot ten, five inches at once! Ashley started shaking her head as she was catching up to her size quickly, “No no no! Stop, you're getting too big!” - “Big...bigger...mmm...again...more...oh fuck...I’m going to outgrow you…” “Nngh! Get off me!” Megan pulsed again with growth, feeling herself overtake Ashley rapidly growing past nine foot five, seven more inches of growth cascaded through her body, now contesting her with her sheer mass. “Aww...are you getting scared...because...I’m...almost...as...big...as...you…?” Megan stopped between pulses of growing to say each word, each word resonated stronger in her voice pulsing with an inch of height growth and mass. She grew bigger...and bigger...and even bigger growing another seven more inches slowing down now to a colossal ten feet tall, meeting her gaze and smiling and then overtaking it, inch by inch. She looked down at Ashley and just simply said, “Amanda is gonna lose her shit when she finds out your greedy little ass destroyed the foyer.” - “Yeah? You big fucking cow, you’re probably going to bloat up like a big puffer fish with all that growth serum you drank…” - “Mmm...yeah...I haven’t even stopped growing yet...are you jealous...mmm...maybe I’ll grow bigger right now…” - “Ok! Stop I get it!” - “Mmm...bigger…” she chanted. “Stop! Please!” - “Bigger...bigger...grow bigger...nngh!” she chanted again and again, feeling her body pumping with hormones, she started growing again on command, reaching down to her soaking wet pussy. “Megan...um...are you sure about…” 

It was no use, Justin’s cries for science were ignored as Megan’s body surged with growth again and again, she shot up inch by inch a few minutes at a time. “Justin! Stop her!” - “It’s...out of my hands…” Justin shrugged and grabbed his erection over his jeans, biting his lip gazing at her amazon girlfriend starting to pump and pump bigger and more bountiful as she overtook the roof and backyard with her height. From her perspective she watched herself soar into the sky past the windows, second floor, and then the roof and chimney until she looked over off into the neighborhood. She grew and grew bigger as she looked down and saw her massive fifteen foot body towering over the two of them. Justin looked like a tiny ant to her and she laughed, bellowing out huge spurts of voluminous laughter towards the two of them. She was then stricken with a surge of pleasure and erotic feeling. Overwhelmed by lust she grabbed the back of Ashley's head and shoved it into her vagina. She forced Ashley’s head and hair getting stuck into her wet pussy, she resisted at first, until finally surrendering and tasting her sweet pussy juice. She licked it up and down, feeling her body pulse every now and then with a few inches of growth. “Bigger! Ugh! Faster! I’m so close! Yess!” Megan screamed as a flood of cum drained from her all over the yard and Ashley’s face, she gagged and recoiled. Suddenly a sound erupts from the driveway as Amanda exits her SUV and looks at the front door, completely ripped off its hinges and on the front lawn. Amanda was more shocked than angry as she looked into the backyard to see a gigantic statue of a busty woman standing next to another gigantic amazon as her eyes widened. She screamed, “ASHLEY? MEGAN? JUSTIN?!” as the three were frozen unable to answer her. They looked back at her as she began to piece together everything, her eyes rolled back and fainted, “Amanda?!” The three ran to her aid, grabbing her with one hand, Megan swiftly held her tight and the three began to nervously think of how they were going to explain this one.
