Massive Models: Day 3 Home

Day 3

Home

His black leather shoes touched the welcome mat outside, as he unlocked the door and walked inside, letting out a loose sigh as he called out; "Tiff! I'm back." There was a slight pause before he heard some movement upstairs, the sound of a vacuum cleaner was suddenly cut off abruptly, quickly heard the slight rumble of footsteps begin to make their way down the hall. Howard made his way upstairs, turning the corner as he saw Tiffany's huge breasts busting out of a tight green tank top, he sighed feeling anxious as her frame came more into his view. She was wearing a now much tighter set of black yoga pants stretched over her new supple juicy ass, she bounced into the hallway panting slightly as she struggled to get used to her new assets, grabbing at her constricting straps around her straining tank top, jiggling and fiddling with it. "Hey Dad." She said loosely as she panted, wiping the sweat off her brow as the rest of the droplets began to form on top of her massive triple H cup breasts, dripping into the curves of her new incredible cleavage. "Almost done?" He spoke softly trying to not rouse her, "Yeah, just about. What's up?" She smiled, starting to feel tired as she stretched her arms over her head, letting her huge breasts jiggle around, her hard nipples were making an impact on her tight top. Howard did his best not to stare, looking off toward the doorway as she began yawning and heading back into her room, her bubble butt bounced in her skin tight pants, gently jiggling up and down, side to side as sweat poured between her thighs.

He followed her, rubbing the back of his neck nervously as he reached into his lab coat pocket and took out a vial of the new growth serum. The long and thin glass tube filled to the top with bright pink liquid slightly flickered under the ceiling lamp light as he cleared his throat speaking up softly. “Hey…Tiff.” He spoke up as she turned her eyes lit up, immediately eyeing the vial, growing wide and eager, immediately acting it off, trying to calm herself down, acting collected as she tried not to seem desperate. "Whoa. Is that what I think it is…?" He sighed again, lifting it up and examining it again for any sediment or anything out of the ordinary. It was clean and crystal clear, he nodded and explained himself. "Yeah, I wanted to come back and apologize for that night. I'm so sorry about what happened. I had no idea what kind of effects my anti-serum would have on either of you, and I should've never involved you two in the first place." - "Aww...Dad. It's ok. I mean, I'm almost back to my old size...plus I did get an upgrade on my...assets…" She smiled looking up at him, comparing heights for a moment, she peered down at his neck and then craned her head up to meet his vision at his tall height of 6'1. In comparison Tiffany was just barely 5'7 now, still shorter than her original height of 5'11. He replied softly, but with some confidence. "Well...if you want, I'll give you this vial of the new growth serum formula...just don't mention it to your sister please."

Her heart began to race looking at the vial as she softly grasped it, taking it out of his hands. "Thanks…" She blushed, hugging him around his chest as her breasts squished up against him. “Yeah…of course sweetheart.” He smiled back, holding her head with his hand, feeling her silky blonde hair for a moment as she sighed before he spoke again. "Oh...don't take too much of the serum before we leave. You're going to have to be able to drive to Victoria's." She blushed, looking up at him as he let go of her. "Right…" She nodded as he let go, looking back at the vial full of bright pink liquid in her hands as he turned to the door and started heading downstairs. She looked around her room for a moment trying to find a place to put the vial, slowly moving her eyes down her huge breasts, eyeing at the long line of bursting cleavage on her chest. "I bet it will fit right in between these monsters." She giggled, stuffing the vial between them until she couldn't see it, feeling the tube between her big breasts. "Perfect." She blushed and then went to work as she looked over at her bed, the last remaining piece of her room she had packed away into the u-haul parked outside. "Looks kinda heavy…" She sighed and grabbed onto the side and tried to lift it, struggling as she started to grunt, feeling her arms strain and her breasts jiggling out of control.

She struggled again against it, pushing herself further, but it was no use. The queen-sized mattress laid there still as she huffed and puffed leaning against the wall after several failed attempts. "Ugh. I'm gonna have to get some help from Howard...or...maybe I could have…a little fun." She blushed, starting to get excited as she felt the tube between her tits. Her hands fished into her giant breasts, slipping her fingers between them until she felt the snug vial finally at her fingertips, releasing it from her booby trap. She blushed feeling the glass tube slide between her tits with a slight pop, she giggled looking at the pink formula sloshing around inside the vial. Tiffany bit her lip, looking at it, feeling her heart beating slightly faster as her hands began to shake. "Just a little bit…" She twisted the cap off and began to take a small sip, opening her mouth and letting some of the pretty pink serum touch her pretty pink lips. As soon as the taste touched her lips she immediately gulped down a mouthful without hesitation. "Mmph…*gulp*" Her lips smacked together as she blushed suddenly feeling warm and fuzzy. "Ooh. This stuff tastes so good…mmph…" She hesitated at first, opening her mouth wider as her tongue began to rest on her lower lip, she panted feeling horny, powerful sensations began to build within her as she panted harder and harder, and then quickly gave in. She lifted the vial back again, feeling the serum touch her lips, smiling more from the delicious flavor. "Oh my god. It tastes amazing...just a little more...mmph *gulp...gulp gulp* She couldn't help herself.

She went back in for more as she drank another mouthful, and then another and another. A couple of long gulps of the potent growth serum drained into her mouth, sucking on the vial as she began to moan softly recalling her old towering size,  getting lost imagining herself growing bigger than her sister, growing into a towering amazon. She got a hold of herself, gulping down one last time before stopping herself from finishing the rest. Over half the vial was gone as she lifted it away from her bouncy lips, kissing the air and smacking them together. They began to tingle and feel warm as they expanded, growing more luscious and bountiful. She licked her lips again, running her finger across them for every last drop as she sucked on them, moaning without hesitation. "Mmm…awhn…that was so good…oh fuck...." Her eyes widened seeing the leftover serum in the vial, now blushing hard and panting slightly, trying to catch her breath. She quickly twisted the cap back on, stuffing it into her underwear by her hips. "I hope that wasn't too much…oh well...erp!" She burped, giggling slightly as her breasts jiggled in her top, she started to grab onto the mattress again when she suddenly began to feel faint. Her vision faded as she began to sweat, chills ran down her spine above her bouncy booty. The feeling crept around her two large ass cheeks into her pussy, suddenly moaning loudly as she felt it begin to throb and pulse with sexual heat. "Oh...mmm…I feel really...horny." She bit on her lip and oozed with desire, feeling her nipples start to become more sensitive, making two hard surfaces on her tank top as she began to slowly move her fingers toward them, she became more eager with every gentle touch of her fingertips.

She trembled again as her fingers treaded over her nipple, feeling her tight yoga pants constrict around her lower half suddenly as her ass began to creep outwards growing larger and more juicy. “Oh…my butt…it’s getting bigger again.” She moaned looking down at her shirt slowly riding up to reveal her belly button, feeling it getting tighter around her waist. She looked down further seeing her pants begin to shift lower, showing her ass even more as it bulged outwards growing huge and incredibly round. The same feeling crept toward her vagina, watching her panties slowly become wet as her pussy ached harder, throbbing out of control as she began to tremble feeling it become more sensitive. "I think it's working...nngh…awhn!" She tried to resist touching herself, suddenly moaning loudly, moving toward her empty mattress laying against the wall. "I need to...sit down for a second...fuck." She sauntered over, pulling the bare mattress towards the ground flat, letting it naturally flop back onto the carpet as she climbed onto it feverishly, starting to feel her heart beating faster. She started to pant hard, feeling the sweat move across her huge bust and onto her nipples. Oh! Awhn!" She squealed, feeling her pussy tighten up as her nipples began to get even more sensitive, flaring up a bright red color and growing bigger as they grew to twice their normal size. “Awhn…my tits feel so weird…what the hell is going on with my nipples…they’re…so sensitive…” Her hands slowly began to massage the area around them, becoming more intense by the second, kneading them more and more as she began to open her mouth and stick out her tongue panting furiously.

She felt a pulse shoot into her nipples, suddenly moaning again as they started to grow in her hands. Her body began to tense up and then release as she started to grow bigger as well, bulging and growing all over. It all happened in tandem, the more she stroked her nipples and breasts the larger she grew. Her hands wrapped around her breasts, squeezing them and rubbing them as they grew into a luscious J cup, filling up into massive mammaries. She felt her moist skin starting to dampen the bed beneath her, rubbing up against it, feeling the fabric begin to tighten as her body began to grow bigger. "Oh...god...it's happening...awhn...why does it feel so good…?" She moaned again as another shock shot her up another inch taller to 5'8 her leggings slid further up her shins as her tanktop began slumping lower and lower with every bulging growth of her chest. Another pulse shot through her as her tank top slid under her breasts as they grew again into luscious double J cups, she quickly pulled off her top, barely able to pull it over her huge bust, struggling to take it off.

"Oh...that's much better." She looked down at them, sweating and panting as she latched onto them, squeezing and twisting her nipples as she completely lost herself in lust. "Awhn…they’re fucking massive...oh!" Her body quivered and trembled growing more as she grew to 5'9 she felt her tight panties struggle against her expanding hips as she suddenly felt the glass tube by her waist begin to dig into her side. "Oh...I don't want to break this little thing…but I also don't have anywhere to put this...mmm…fuck it.” She dug her hands into her panties lifting out the vial as she twisted off the cap and immediately began sucking it down. "Mmph...that taste! Mmm! *gulp gulp gulp*" Her huge lips wrapped around the vial, drinking down the rest within seconds as the bottle emptied into her mouth. "Oh god…I drank the whole thing...haha…hahaha!" She began to giggle and grin devilishly, blushing a deep crimson as she rolled the empty vial across the mattress, laying down its length comfortably. Her laughs became softer and longer as her hands began massaging her body up and down, slowly moving toward her giant breasts with her left hand as the right motioned towards her incredibly wet vagina trapped in her ever tightening yoga pants.

She laid there sprawled out topless as her body grew bigger, expanding against the bare fabric of the naked mattress. Constant pulses of tingling energy shot through her body, making her expand and grow more luscious and thicker, her already curvaceous body began to become extremely voluptuous. Her hourglass figure became even more noticeable as her ass bubbled up and up becoming massive and juicy. Her incredibly bouncy ass only grew wider and more round as her hips widened in response to her constant rubbing of her hand on her soaking wet vagina beneath her now tearing pants, showing bits of her light peach colored skin showing between the tears of the fabric. Her entire body shuddered at once as she grew to 5’10, her leggings slid further up her legs past her shins toward her knees as she felt her ass bubbling up even bigger. “Oh my fucking god…I feel like I’m getting heavier…oh god, yes…bigger…I want to be fucking huge!” Another wave of growth shot through her as she trembled, growing taller to 5 '11, back to her old height, however she was extremely thick now; with incredibly large breasts that only filled up more as she grew, now grown into luscious K cups.

She couldn’t hold back any longer, her hand reached into her pants, starting to finger herself as she felt her wetness coat her hand in her own juices. “Oh fuck…I’m so wet…oh…oh…oh!” She fingered herself deeper and harder as her tongue stuck out further out onto her big juicy pink lips, her eyes rolled back as she felt another wave of intense pleasure wash over her she began to climax. “Oh FUCK!” She screamed, trembling hard on the bed as she clutched the mattress releasing a powerful orgasm, squirting all over herself and her pants as she made a mess of herself, oozing all over her thighs and legs. She sighed, letting go as she pulled her hand out of the wetness now starting to get colder against her aching vagina. “Oh my god…that was intense…awhn...” She moaned softly as another pulse of growth shot through her body sending her to 6’0, stretching her pants to the limit as she heard a loud rip come from the backside of her soaked and ripped yoga pants. Her ass and hips had busted out of them, showing off her huge booty swallowing her panties up between her luscious ass cheeks. “Guess I’m not done growing yet…I’m so thirsty though…” She got out of bed, feeling her wetness rubbing against her thighs and legs as she looked down and felt the area around her butt, looking at the remains of her torn pants as she felt the long tear down the back feeling her ass sticking out.

“Oh my god…my ass is fucking huge now…awhn…it’s so fucking big.” Her pussy trembled, feeling her tight little panties wedged into it, being pulled further up by her giant bubble butt now twice the size it was before pushing it out further. “Nngh…it’s so tight…and wet.” She pulled it loosely biting her lip looking at a massive circular stain and a long line of wetness tracing down to her backside as she blushed, pulling her pants down, followed by her soaked panties off her wet vagina which left a few sticky strands of her moisture on them as she pulled them away, moving her hand down to the area, rubbing it slowly as she began to touch her huge K cup breasts with her other hand instinctively. Her hand overflowed with soft breast tissue, squeezing and lifting her tremendous breasts, struggling to contain them as she twisted her nipple, latching onto it and moaning as her tongue crossed her lips. “Still…so horny…awhn…I have to stop…turning myself on. I need to get dressed and get going before I start growing again...” Her bouncy body jiggled and moved with lumbering motions as she adjusted to her new weight and oversized assets, nearly falling over as she made her way to her dresser. “Christ. These things are so heavy…and this big booty makes it so hard to move around.” She reached down grabbing a handful of her ass, blushing and biting her lip as she moaned softly letting it go, watching it jiggle and slap against her other huge booty cheek. “It’s so fucking juicy…ugh I’m not gonna fit into anything now, my panties look like a thong on this huge booty.” She pouted, opening the drawer as she filtered around her clothing to find something that could fit her new bodacious body. Her hand reached down to her vagina, patting it softly as she felt her hand immediately get sticky and wet, she blushed hard looking at the doorway. “Maybe…I should take a shower first.” She hastily donned a shower robe walking out of her room as she heard footsteps coming up the stairs.

Howard made his way up the stairs as he noticed her walking by, he approached her, holding fresh towels and a water bottle. “Hey, I just got some new towels and you looked really thirsty earlier so I brought you some water.” - “Oh my god. Thanks! Mmph..mmph…” She was ecstatic, approaching him and taking the bottle off the top, opening it and starting to chug down a few large gulps. Howard quickly noticed her new body, taller and much more filled out, he scanned her from head to toe, starting to feel nervous seeing her immensely voluptuous body barely covered up by her tight bathrobe. Her hourglass figure was extreme now, her huge hips made her massive ass look like a round and juicy peach, complemented by her equally giant breasts that were already showing a long line of cleavage beneath her bathrobe. “Wow…you’ve definitely grown...” - “Mhm…mmph…aah. Yeah…thanks I feel much better, looks like your growth serum works really well Dad.” She smiled, taking her puffed up lips off the bottle, seeing her eyes nearly lining up with his as he stared back with a half smile, looking worried. “Hey…what’s wrong?” - “Oh…I just couldn’t help, but notice that you’re a little bigger than you were before.” - “Yeah…I don’t see what’s wrong with that. The other girls…are really tall and sexy…” She twisted her lip growing green with envy as she quickly recalled her sister's towering size, turning red with embarrassment as another rising feeling began to build inside her. “Oh…well yeah I suppose you’re right. Another inch or two won’t make a huge difference.” Howard said reluctantly, as he turned his head to the bathroom door. “Exactly…anyways, I should really take a shower.” - “Oh. Of course.” She blushed moving past him slightly as she got closer to the door, she felt a kick in her stomach followed by a cascade of tingling sensations through her arms and legs. “Nngh.” She grunted, holding onto her belly as she felt another rise shoot through her body as she grew taller to 6’1, she let go, standing back up to her full height as she turned to him seeing her eyes lining up with his now as she smiled wider. “Are you ok? Whoa…wait…are you my height now?” - “Yeah…I’m still growing…” - “How much did you take?” - “Well…I tried to move the mattress on my own and- nngh!” She was interrupted as she felt her curves pulse and bounce as she trembled. Her body only grew taller as she watched her perspective rise again, watching him shrink an inch lower as she rose to 6’2.

"Tiff…." Howard stepped back slightly as she rose taller, growing faster as another growth spurt began to pump through her already luscious physique. "And…I thought maybe if I drank some of the growth serum it would be easier to carry stuff if I was bigger and taller, I'd be stronger too…right?" She inched upwards to 6'3 as her breasts began to push against the loosely tucked in towel around her arm, growing bigger as they expanded. "Tiff…how much did you take?" She continued to grow taller again to 6'4 looking down a few inches taller than him now. "Just one…nngh!" Her body trembled again, growing stronger and larger as his in comparison shrunk inch by inch as she rose taller again. "You didn't drink the entire vial already...did you?" Howard started to get annoyed, watching her rise and grow into an amazon. "Sorry...nngh!" Her body pulsed bigger, growing to 6'5 as her towel slipped downwards around her growing body, slowly shrinking in comparison.

"I didn't...nngh…mean to...awhn!" Her progressive grunting turned into intense sexual moans as she rose again taller to 6'6 as he watched her rise over him, growing bigger and bigger rapidly. "I told you...not to take the whole thing." Howard huffed watching her begin to smirk as her breasts filled her hands, she couldn't hold onto her towel anymore, it fell to the floor she boomed taller again to 6'7, feeling her massive breasts filling out to ludicrous L cups, completely overflowing and spilling out of her robe now treading farther up her legs close to her immense bubble booty. "It's not...stopping...I keep growing...awhn…" She exclaimed seeing the top of the bathroom door frame begin to level with her perspective. It didn't stop there she quickly felt another kick as her eyes slowly rose over it, growing bigger and bigger without pause. She rose again to 6'8 and then again to 6'9 as her body began to widen around her hips and legs becoming thicker and more erotic. "You need to get moving sweetie...you're going to grow at least another foot-" - " Another foot?! Oh my god...how tall is that…awwhn!" She moaned louder as her body expanded, becoming insanely luscious and juicy, her ass bubbled outwards as her legs grew thicker and longer. He couldn't stop staring at her rapidly developing body, he watched her body rise up again to 6'10, his breath drew harder and more constrained the more he watched her ascend. Her body was on fire as she finally grew another inch taller in one large growth spurt now an entire foot taller than her previous height, standing at a powerful 6'11.

She gasped looking down at his head now 10 inches below hers, craning her head down slightly to see his eyes lining up near the bottom of her neck. "I'm so...sorry I didn't realize this new stuff was so strong…" She blushed, feeling embarrassed, but slightly smirking as she felt her vagina was throbbing with intense sensitivity and absolutely soaking wet, her cheeks a deep crimson trying to cover herself up a bit as she bent over and grabbed the towel off the floor. She held it up to her newly grown body and immediately started to laugh as she looked at how little it was covering her up. She tried to tie it around her chest, lifting it up to their huge size, jiggling them around as Howard quickly cleared his throat and softly spoke up. "Tiff…" - “Ok! I’m going dad…” She rolled her eyes, quickly stopping at the door frame. "Oh my god…I'm taller than the door." She mumbled as Howard rolled his eyes in response, starting to turn to move away. She giggled before ducking under it and heading inside the bathroom.

He rubbed his eyes and started making his way into her bedroom, quickly spotting the empty vial and stained mattress sideways just dropped on the carpet without a thought. He felt a buzzing noise in his coat as he reached in, taking out his cellphone. “Hmm. I don’t recognize this number.” He answered anyway, opening it to hear some noise in the background immediately, like some kind of argument, but muffled and indecipherable. “Hey! Is this Howard?” - “Speaking.” - “Hey, this is John! Listen, I need some of that growth stuff, we’re putting on a brand new modeling scene called Massive Models, and I need as much of that stuff as you got.” - “It’s not…for sale.” - “Aww…come on Howard, we could both greatly benefit from this arrangement. And listen, between us, your daughter is loving her new job.” - “She’s working at the agency now?” - “Yeah! Hey tell you what, if I send my girl Holly over there, I’ll pay you for all the stock you have right now, name your price.” Howard stopped for a moment, pondering everything as he suddenly recalled Victoria and her new colossal size. “Hmm…ok we can talk about the price later, I have two vials on hand right now.” - “Perfect! This is the start of an incredible friendship, Howard. I’ll send Holly over now.” - “Ok. Great.” Howard closed the phone as he rubbed the back of his neck nervously, feeling the inside of his jacket as he felt the two vials secured in his coat pocket. He shrugged, picking up the empty vial and making his way downstairs as he heard stomping from inside the bathroom. “She’s probably still growing bigger…I hope she doesn’t break anything.” Howard thought as he felt the vibrations from her feet colliding with the shower tiles shake the railing slightly.

Torn and shredded clothing were strewn about the floor in the bathroom, hot steam crept around the tall golden blonde haired amazon covering herself in sudsy soap. The shower head was blasting out hot water, steaming up the sides of the glass shower door. Tiffany’s head was sticking out of the top of it, comically oversized for the shower, barely able to fit inside it as her head was only an inch away from the ceiling tiles. "This is so weird…I can see over the door…I'm so tall…I feel so powerful…" She thought, as her body quivered in delight, feeling the warm water soak into her smooth skin and luscious curves. She cooed, massaging her watermelon sized breasts with soap as she felt them begin to swell slightly in the heat. She looked forward seeing the shower head barely reaching her neck as she looked down watching the water splashing between her massive line of cleavage and all around the curvature of her huge tits. “I’m too tall…mmm…awhn…I’m so big…” She moaned, feeling her body begin to tingle, massaging her luscious breasts that began to bubble up as her nipples got hard. She pinched them cooing softly as her other hand treaded down towards her aching vagina. Her hands methodically rubbed it moving up and down when suddenly she felt a pulse shoot through her jiggling wet body. She roared in pleasure again as she slowly began to grow taller, first to 7'0 tall cooing and moaning softly. “Mmm…not again…” She said sarcastically before she bounced upwards, growing taller again to 7'1 as her head bumped the ceiling with a soft thud. "Ow...oh...I'm too big for the shower now...oh!" She jumped again as her head pushed further against it as she continued growing taller to 7'2. Her head craned forward as she felt her shoulders eventually touch the ceiling as she passed 7'3. As she continued to grow bigger and bigger she tried her best to wash herself off, she sighed looking down at the small bar or soap resting in the palm of her hand. Looking down at it every so often seeing it becoming smaller and smaller as she continued to grow now cresting 7'4 as she moaned finally placing the soap back on a small ledge, having to bend all the way down to its height. She stood back up, accidentally bumping the showerhead. "Oof. Damn it, everything feels so small, I gotta get out here."

Her two large feet collided with the soft mat outside the shower door as she stomped out of the shower, soaking wet, ducking her head and tucking her shoulders out as she felt her wide hips get trapped between the door for a moment before she slipped through it feeling her jiggly ass sliding against it. "Oh fuck...I am getting way too big...I could've been trapped in there, I gotta get moving…" She paused looking down at her tremendous body in the mirror. It was barely as tall as her shoulders. She looked down, craning her head to see her gigantic breasts in her reflection as she grabbed them, slowly massaging them as she watched them perk up. "They're...beautiful...mmm…" She moaned, squeezing them as they overflowed in her arms, teasing and massaging them as she started to feel the tingling sensation returning. "Oh..more...yes...bigger…" She pleaded as her breasts began to expand again, growing absolutely gigantic, like two massive beach balls they grew and grew, bigger and bigger. "Awhn...bigger." She chanted as her breasts filled up in her arms growing softer and larger as they filled up, growing several cup sizes bigger into incredible O cups, trembling with erotic sensations. "Oh my fucking god…theyre enormous…what am i going to do?!" She clutched onto them feeling her entire body shake as she grew taller again, another inch to 7'5 as she felt her back rub the ceiling again, pushing further against it as she craned her head even lower. “Oh fuck…I can't even fit in here anymore…I gotta get out of here and find something to wear.”

She looked down at her tremendous breasts, unable to see past them as she moved toward the towel rack, ripping one off as she tried to wrap it around her chest like a bra, her hands fished around her back, moving the towel behind her wide shoulders as she adjusted it around toward her chesty front half. "Oh god...it won't fit." She struggled trying to wrap it around seeing the ends of the towel barely meeting halfway across her huge bust, jiggling and stomping around as she felt another kick in her stomach. "Nngh...more…fuck..." She bit her lip feeling her body tremble with growth as she grunted feeling her knees start to have to bend as she lifted a hand toward the ceiling. She started to get worried, struggling to fit inside, barely able to stand up as she passed 7'6 tall. “I can’t believe I got this big…off of just one vial…maybe it was because I drank her…ugh…I don’t even want to think about that right now.” She rolled her eyes, wandering out of the bathroom as she reached down, clutching the doorknob with her entire hand as her eyes widened, taking in her new size. “The doorknob…feels like a little toy in my hands now…nngh…why does that turn me on…” She twisted it, trying not to smash it in her hands as she reached outside of the bathroom, clutching onto the sides of the door frame as she bent down and ducked out, standing back up to her full height beside the doorway. She chuckled, seeing the top of the doorframe half a foot below her head now resting at her chest height. “Everything feels so small…I need to get dressed…what the fuck am I going to even wear…”

Howard sighed waiting in the kitchen as he heard loud footsteps coming from upstairs, it continued for quite some time, listening to the loud creaks above him only grow louder. He looked down at his mug sitting at the table, slowly vibrating with every stomp he heard coming from above him. Suddenly he heard a few knocks on the front door, as he slowly paced towards it, he opened it looking down at a cute and short redhead. Holly smiled, and looked, craning her head all the way up his tall height of 6’1, compared to her short height of 5’2, he was almost an entire foot taller than her small size. She felt a bit nervous seeing his shoulders looming over her head, as she looked down to see his broad chest near her eye level, she felt dwarfed by his size and tall stature. “You must be Holly, I’m Howard.” - “Yeah, John said you had some kind of growth potion or something…?” - “It’s a growth serum, synthesized from the Godessa flower, a plant known for its ability to grow rapidly and affect other flora with it’s bountiful properties…although it seems to be quite effective at making women become taller as well…and more…filled out…that’s for sure.” She tilted her head acting cute, trying to play off her incredible desire to grow into a tall amazon. “Wow…so…how much did you want for it?” Holly smirked watching him pull out two vials as he handed them over to her. She held them for a moment looking at them glow slightly in her hands, the two clean glass vials were filled to the top with the growth serum, she moved them around watching the liquid slowly move around inside. “I don’t know…I don’t usually charge for science.” - “How about…” Holly smiled and reached into her purse, retrieving a stack of hundreds, placing them on the counter beside him. “Oh…I couldn’t-” She cut him off abruptly, placing one vial into the purse and opening the other, twisting off the cap as she grinned devilishly. “Oh don’t worry…you’ll have plenty of time to make more of this stuff.” She lifted it up to her eyes, examining it when all of a sudden another resounding crash came from upstairs. The two of them looked up seeing a large jagged break in the ceiling begin to form, growing longer as rubble crumbled off the ceiling onto the countertop. "Shit...I'll be right back." Howard quickly ran off, rushing up the stairs as Holly looked at the vial in her hands nervously.

Holly's heart was beating out of her chest as she heard him hustle up the staircase calling out to her; Tiffany?" Holly started to slowly roll her eyes as she smelled the serum, taking in the sweet floral scent before taking a small sip. She tapped her lips together, tasting the sweet serum on her tongue as she shrugged, tilting back the vial and drinking some more. "Mmph...tastes pretty good...mmph…*gulp gulp gulp*" She could feel the cold liquid trickle down her throat as she continued to suck it down slowly. "Mmph...mmph...mmph...aaah…" She let out a pleased sigh as she finished the entire vial, smacking her lips together as she reclined back into her seat, starting to feel the euphoric effects of the formula take root. "That should be...good for now...I can always take this other one later…" She smiled, looking at the empty vial in her hands, remembering her last encounter with Laura, "She was so big...and busty. I hope that's enough to grow to at least half her size, she looked incredible." She burped feeling her stomach begin to churn as she felt faint, starting to sweat as her blouse began to get damp. "Oh...starting to feel kind of hot...mmm...and warm and...a little fuzzy…mmm...haha…." She mumbled, smiling and laughing slightly, moving her hands towards her small B cup breasts, like two little lemons tucked away under her reddish pink blouse.

She could feel them tightening and then filling up as she began to hold onto them feeling them grow in her small hands. "Oh...feels good." She mumbled as they filled up her hands as they began to grow bigger, she cooed massaging them gently as they expanded. They grew and grew bubbling up in her hands as they filled up into large C cups fairly quickly into small apple sized breasts. "Whoa...it's getting more intense...awhn." She moaned as her nipples began to get hard, rubbing against her black bra beneath her white blouse and suspenders. Her emotions started to fire up, straddling the chair beneath her as she began to hump it slowly getting more horny. "Aah...fuck they're filling up...I've never had big tits before...awhn!" She panted harder, gyrating and grabbing her breasts, rubbing her hands against the fabric of her top as her tits grew even larger she moaned harder. They started to fill out her top, growing against her blouse as they bubbled up into D cups, filling up like two large grapefruits in size. "Awhn...it feels so good…I'm so fucking horny." She drooled, moving her hand up to her mouth, wiping it off as she felt her lips puff up against her arm. She gasped feeling her now bountiful lips growing even bigger. "Mwah...my lips are getting so...juicy." She kissed the air struggling to stand still as she started fidgeting around feeling her vagina start to throb. "So...wet…" She mumbled again out of breath as her breathing became more labored. Suddenly she felt a slight bounce as her perspective jumped up an inch as she grew taller to 5'3, her legs began to grow bigger and stronger. "Uh...I think I'm starting to...grow...oh!" She felt it again, another jump up as her eye level shifted upwards again and didn't come back down as she grew to 5'4. Her pants slid up her ankles as she continued growing taller, starting to strain her feet as well, and slipped into her work shoes. "Ugh...everything is starting to feel tighter...I'm definitely growing now." She blushed again, feeling her body starting to get warmer, sending sexual vibrations across her skin as she bit her lip. "I should...get back to the studio." She mumbled pulling her chair back as she stumbled getting out of it.

She immediately felt the weight of her newly grown breasts, she slumped forward holding them as she moaned loudly. They started to fill up and up as she tried to straighten out her back. They doubled in size, suddenly growing from D cups into DD cups and then further as she massaged their expanding size, becoming more and more entranced by the sensation. They became incredibly sensitive in her fingers and she kneaded them, massaging them against her chest she felt them bubble up even more as they grew into luscious DDD cups, filling up and up into melon sized mammaries. She couldn't stop, her tongue crossed her lips as she moaned, letting out hot breaths, now panting heavy and moaning as she looked down watching her breasts expand larger and larger. She could feel the suspenders getting tighter around her shoulders as her breasts continued to fill up more space inside her straining bra as it finally snapped. "Oh fuck!" She yelled trying to hold back from moving her hands down toward her soaking wet throbbing pussy. She stopped fondling herself, trying to focus, motioning her hands toward the doorway. She shuffled towards the doorway, holding onto the frame as she suddenly felt another kick in her stomach. "Ugh...awhn…" She let out a slow muffled moan as her pants began to fill out, growing a bigger bodacious booty as she continued to grow thick thighs to accompany her new bubble butt.

Another pulse shot through her body as she rose again her ass and thighs continued to bulge and grow larger. "Oh god...my ass is getting fucking huge!" She felt her panties quickly get sucked between her now huge bubbly butt cheeks as she squealed in pleasure feeling them wedge into her pussy. She twitched, lurching forward as she grew again to 5'6, feeling her shoulders begin to catch on her tight suspenders now riding closer to her upper torso. "Nngh...everything is too tight...I gotta take these off." She reached over to unlatch her suspenders, feeling them constrict even tighter again as she continued to grow bigger into 5'7, straining to twist the metal button holding it together. She stumbled towards the door, holding onto her chest as if she suddenly felt a rising pressure building within her body. “I can’t…get them off…it’s too tight…ah!” She clenched her teeth as she began to bounce up and up, growing rapidly, her blouse ruffled upwards, showing her belly and tan skin as she inched up and up growing even faster as she rose up to 5’8, growing several inches at once. She held onto the doorframe feeling her hands slide up again and then again as she felt dizzy, watching her perspective jump up and then up again. She continued growing bigger as she passed 5’9 within a few seconds. Her legs grew longer and thicker as she rose taller, becoming more womanly as she rose upwards. Her heels snapped off as she felt the cold tiles under her collide with her bare feet. Then came her buttons, finally coming loose, popping off her shoulders and down near her tremendous breasts as her two suspenders flew forward, clacking onto the wall falling past her chest down to her knees. “Oh my god..hah…hah…it’s so intense…awhn!” She moaned, feeling her panties begin to tear around her widening hips and thickening thighs as it tore open around her backside, ripping her panties off her now bulging bodacious booty. She finally caught her breath, standing back up as her red bra slipped under her blouse, falling to the floor. She looked down at her damp white blouse now riding high above her belly, her two big tits, showing her rock hard nipples poking out from under it. “Whoa…everything looks…smaller.” She said as her hands treaded over the door frame, seeing her ripped clothing on the floor.

Her heart jumped suddenly hearing stomping coming from upstairs, she turned gasping as she felt a slight draft cool her bubble butt, quickly realizing she was going to be totally nude in the next oncoming growth spurt. Tiffany came stomping down the stairs, bending down barely able to walk properly with her absolutely titanic breasts jiggling and bouncing around as she made louder impacts with her huge bare feet against the wooden staircase. She struggled, sighing and scoffing as she looked down standing upright in the hallway downstairs after bounding down the last few steps skipping some without noticing.

“Ugh…I can barely walk down these stairs…I’m so fucking big now, my feet can’t even fit on these steps.” Tiffany thought as her tremendous amazonian bodice stomped down the staircase, standing up to her full height as she looked down to see Holly nervously covering her nipples poking out from her top now riding below her blossoming DDD cup breasts. She laughed at first, looking at the ceiling lamp only a few inches away from her seven-and-a-half-foot-tall amazon body. Tiffany could barely see her underneath her colossal breasts, they were like two juicy melons hanging off her voluptuous top half, leading down to her wide heart-shaped hips down past her clean-shaven vagina and long thick legs that held up her giant bubble butt. She motioned her hand down to her head, measuring it against her curvaceous body, seeing it line up under her humongous boobs. She smiled, pushing out her bountiful lips as she looked down at her still struggling to hold onto her torn and tattered clothing as her eyes slowly panned all the way up to her two bright green eyes and the rest of her face covered up by her giant breasts.

"Oh! I can barely see you all the way down there! Hey...Holly right?" Holly's eyes went wide looking at her blushing bountiful bodice completely nude in front of her as she began to feel a rising pressure building in her legs. She blushed as she felt it moving up her thighs and toward her pussy, throbbing intensely as she looked up, biting her lip trying to respond. Suddenly she felt a pulse shoot through her as her body trembled, jiggling intensely. "Y-yeah...nngh!" She twinned rising upwards another inch taller to 5'10, finally snapping her panties off at her hips as she felt them loosen under her tight pants, barely hanging onto her expanding booty. Tiffany tilted her head slightly, noticing her new size and ripped clothing starting to realize what was happening. "Did you just...grow?" Holly trembled again as she bounced up another inch taller to 5'11, clutching onto her chest as it began to tingle intensely, cautiously massaging them as she cooed again, moaning lustfully as the sensation began to build inside her even more. "Mhm…Hah...hah...nngh!" She panted harder and another wave of growth passed through her body like fireworks, her nipples immediately got hard, sending sensitive vibrations through her system. “Oh my god…you’re really filling out.” She began to grow thicker and more voluptuous as her pants tore down her thighs shredding off her legs. She blushed to crane her head far up to her towering figure, as she mumbled looking at the door behind her, nervously shuffling trying to avoid growing any further. "Yeah...you're so...much bigger than me though…" - "Yeah! I got huge. Hahaha!" Tiffany laughed, sending cascading waves of jiggles through her voluptuous frame. Another louder moan erupted from Holly as she rose upwards in a few short spurts, her clothing one by one shredded off as she clutched her chest that began to bubble up even bigger in size. Her curves rippled as she rose taller to 6’0 feet tall widening her eyes as her perspective made its way up her tantalizing body with every growth spurt, she bit her lip, trembling and sticking her tongue out slightly as she licked her lips, rolling her eyes around feeling dizzy and euphoric as the final growth spurt ran its course through her system. Her breasts began to expand outwards rapidly, filling up her hands as she desperately tried to cover her growing body with the remaining shreds of her overalls and her torn-up white blouse, now scattered around the front door and welcome mat under her bare feet. She filled up, growing into luscious E cups, growing bigger and filling out further, she trembled harder as her hands slowly moved toward her mouth, trying to cover her huge breasts with her arm and elbow, as her finger motioned across her large lips that were now bountiful and puffy like two clouds.

Her breasts expanded larger and larger as they grew, blasting into massive melons within seconds, rising taller, bouncing up and up as she grew to 6’1 tall. Her breathing finally slowed as Tiffany pouted seeing her new voluptuous and tall body, quickly calling out, “Hey, you should like…find some clothes.” She looked back, hearing the familiar footsteps of her father pacing down the stairs behind them. “Hey, sorry about that Holly, I didn’t want to- Oh!” His eyes widened seeing Holly now standing at the same height as him, looking eye to eye and now boasting two massive double G cup breasts in her hands as she looked over towards him with envy, lowering her eyes slightly to match his before she started to giggle and respond casually. “Your serum works wonders, Howard. I’ll be back soon for some more, but I really gotta go find something to wear…” She smiled, looking up at Tiffany before she turned, grabbing her purse and standing base to base with Howard, now the same height, but much stronger and heavier. “You’ve grown a lot already...in such a short time...how much did you take?" Howard was baffled again at her rapid growth, she had grown an entire foot taller, he blushed trying not to stare at her hands clutching her two juicy cantaloupe-sized breasts. Howard looked up at Tiffany as she sighed and placed her large hand on his shoulder as he sighed back, giggling before she responded. "Just one, don't worry. Just make sure to start the next batch soon. All our girls will want to grow as tall and busty as me, if not bigger-." He cut her off, acting with authority. "An entire vial? I should've mentioned this version of the serum is a lot more potent than the last.” - “I feel fine…honestly I feel incredible. I've never felt this good in my life!” Holly smiled as her eyes got heavy, she moaned as her body suddenly jumped up another inch taller to 6’2, her eyes slowly panned down lower to his widening gaze, she grinned feeling the warmth returning to her again. “Maybe you should wait here a little while, just to see the full effects of the serum before you-” - “Mmm…awhn…I really should get going-” She moaned softly, interrupting him as she grew taller another inch higher to 6’3, groaning and stretching her arms above her head. "...grow any bigger…" He stammered listening to her erupt with loud cooing, growing again another inch taller to 6'4, becoming thicker and larger as her ass and thighs bulged out larger. Her legs quivered with pleasure, squeezing them together, she came hard blushing as her fantasies finally were realized, shaking and moaning.

Howard blushed, trying to avert his eyes as she roared with pleasure. "Awhn...god...I think it finally stopped…" She blushed harder looking down at his eyes a few inches below hers now, standing a few inches taller than him. "That's good...you've already outgrown me...and I'm pretty tall-" She cut him off abruptly, jumping up and down shaking her large breasts as she giggled in response, "Yeah! Oh my god! You used to tower over me when I was shorter than you...but look at you now…you’re a couple inches under me." She said smiling wide as she looked down at him, blushing hard and seeing her perspective now lining up over his head. "Wait...how tall are you?" - "I'm six foot one…you grew…a lot." - "Oh my...I must be close to six and a half feet tall now...haha!"

She laughed scanning her body beside his, looking down at her massive breasts and bulging ass as she blushed again suddenly surprised by Tiffany yawning above them as she giggled and placed her hand on her head. "Aww...it's too bad you didn't grow that much, you still look a little short to me actually..." She grinned devilishly, shooting an enticing look toward her as she responded with a cute bewildered look before panning over to Howard as he rubbed his eyes in frustration. "Don't encourage her, please, she's gotten big enough already, she doesn’t need any-." She cut him off again, cooing as she sighed looking down at her handbag, seeing it much smaller in comparison to her new size. "Oh...that's right there's another vial...mmm...tempting. I'd love to grow some more…maybe another foot taller...become an amazon like you Tiff..."

She craned her head up to her two gleaming eyes buried under her massive breasts. "Do it! We could be twins!" She grinned devilishly in response looking back at Howard as he gulped quickly looking back down at her hands now fidgeting near the opening of her bag. “Mmm…that sounds like so much fun!” Holly reached into her purse, giggling as she started taking out the second vial, Howard immediately started to sweat and get nervous, quickly remembering her former short and petite figure, now grown into a powerful six foot four bodacious filled out amazon.

She began to twist off the cap and suck down another tall vial of the growth serum, she lifted it up to her luscious lips, resting the glass rim on her tongue as he watched in horror as the vial drained down, listening to the slow gulps of the serum trickle into her mouth. “Mmm…mmph…” - “Wait…no…Holly! Stop!” Howard hesitated at first as he started to get curious about how a double dosage would affect Holly, suddenly changing his tune, as he began shouting. Tiffany above the both of them began to widen her eyes, coming upon the realization that Holly may outgrow her with this next dosage, clearing her throat as she started to respond nervously. “Hey…maybe…like don’t drink the whole thing…oh…fuck…” She gulped seeing the last remaining pink liquid drain into her mouth as she sucked the entire second vial down quickly and with ease. She giggled starting to grin devilishly, lifting the empty vial up to her eye level before responding to the other two. “Oops…sorry…it was so tasty! Haha!” She giggled again looking down at him again as she started to blush, moving her hand slowly towards her bare nipple, still topless from outgrowing her clothing. She moaned softly, feeling the effects of the second large dosage begin to take effect, she stumbled dropping the vial onto the floor with a resounding snap as the vial broke into pieces at their feet. “Holly…oh god, you shouldn’t have had another…Holly!” - “Ughh…”

Howard shouted as he watched the glass break, sending shards across the hardwood floor. Tiffany gasped, widening her eyes and staring at Holly’s body begin to tremble and become wet all over, she started to sweat all over her curves, sending her body into a passionate lustful heat. “Ohh…hah…hah…hah…it feels…so much more intense this time…aah!” Her hands began to motion up and down and around her nipple, latching onto her large breasts as she massaged them more and more, driving herself wild. Her other hand began to fish down to her panties still trapped in a tangle of her shredded overalls hanging down under her massive bubble butt that began to blow up bigger. It ballooned in size, growing larger and thicker as it began to consume the space around it, ripping and destroying whatever leftover bits of clothing she was trying to hold onto finally hit the floor. Her breasts followed suit, bubbling up and up as they grew several cup sizes at once, first growing into massive H cups and then bigger and even juicier as they grew into huge J cups hanging off her chest. She then jumped upwards in size growing larger as he watched her climb up in height, growing to 6'9 tall in seconds as the dosage kicked in quickly, she smothered Howard with her growing breasts, pushing and squeezing them on his face as he began to cough trying to gasp for air. "Holly!" Tiffany gasped seeing his struggle beneath her as she reached down and grabbed her arm, pulling her off of him as she felt her weight on her arm struggling to move her as she began to grow even larger. "Mmmmm…awhn! God! My body feels so weak…I can barely move…ugh…" She only grew more as her body shifted and expanded, becoming thicker and stronger, rising taller and larger. "Let go of him! Ugh! You're so…heavy!" She pushed her again, shoving her against the wall away from Howard. They struggled as he suddenly caught his breath looking up at Tiffany trying to hold onto Holly's nearly unconscious body going limp in her arms. Her eyes rolled back as she continued to expand and grow outwards, gaining weight and mass as her frame became more colossal.

Tiffany held on feeling the weight on her shoulders and chest begin to slowly push her down as Holly's voluptuous body only grew bigger and bigger. "Argh! Holly!" She fell to the floor, planting onto the rug in the foyer, barely able to move as she was pinned down by Holly's growing body, pulsing bigger and larger as her breasts began to smush onto hers. Holly moaned in a lustful daze, latching onto her arms as she felt her body pulse again with growth passing 7'0 feet tall as she continued catching up to Tiffany's amazonian size of 7'6. As Tiffany started to push her off she felt her body pulse with growth suddenly expanding and growing in size as she grew to match her size within a few short seconds. Her body bulged, growing and expanding outwards as she struggled against her; she soon realized her body had been surging with increasing mass and muscle. Holly rapidly grew past her size, still increasing in height and weight as she began to crush her beneath her towering thighs that had grown to an incredible thickness. She was easily taking her down now, pinning her to the floor as she gripped her hands tighter around her forearms, she slammed her further onto the floor, reaching down and pushing her growing body further into her face. "You're getting so big–mmph!" - "Mmm! Yes! Yes! Yes! Ive always wanted to be a fucking amazon…god even you look small compared to my massive fucking body now…hahaha!" Howard marched up triumphantly toward the two fighting amazons, he swallowed his fear, treading closer to Holly’s soaking wet nude body smothering Tiffany beneath her tremendous thighs and titanic ass. He craned his head up as she finally let go of her arms, now starting to look much smaller in her large hands as she lifted her large upper half still sitting on her chest as she looked over to him smiling.

Howard looked up and called out, “Please, get off her.” - “Seriously! Ugh!” Tiffany struggled, fidgeting and pounding her hands on her thighs as she giggled, biting her lip. “Awhn…it won’t stop…look at you getting so small…awhn!” Another surge of growth washed over her as she felt her hands bounce off more, jiggling and growing as her lower half got consumed by her curves. "More! Bigger!" Holly shouted as she continued to grow and grow as she rose taller, becoming wider and thicker, growing into a powerful mini-giantess with every bounce on her chest as she blushed, feeling her vagina about to erupt. “Holly! Enough!" Howard shouted as the two of them suddenly yelped hearing his assertive voice echo in the hallway. Holly boomed another foot taller growing into a powerful eight foot tall menace, as she continued to crush Tiffany under her ever thickening thighs and giant bubble booty. She laughed, sending her voice echoing through the hallways as her body continued to grow at an alarming rate, first shooting up to nine feet tall within seconds as she shouted. "What are you going to do about it? I'm going to outgrow this entire house, just watch me grow bigger…" Her body doubled in size as she passed ten feet tall you could hear Tiffany choking for air now three feet larger than her counterpart trapped between her growing thighs. "Bigger!" She roared as she climbed to twelve feet tall shaking the floor and ceiling as she started to run out of room for her tremendous size. "Bigger!!!" She screamed one last time as her head and arms crashed through the ceiling, destroying everything in her path when suddenly it all faded to black.

A cold chill ran over her lips as she awoke on the couch in the living room, Tiffany sighed looking down at Holly, laying on the sofa. “Hey…are you ok?” - “W-what happened?” Holly spoke softly looking down at her large double G cup breasts and slender over six foot tall body sprawled across the couch. “You passed out, you said you felt great and then started looking all woozy, so I picked you up and you fell asleep here…you looked so cute.” - “I guess…it’s some weird side effect of the growth serum, maybe I shouldn’t have had the entire vial.” - “Nah…you look amazing!” Tiffany smiled wide, boosting her confidence as she nodded and moved her hair out of her face. “Really?” Holly's eyes beamed toward her, as she smiled in return, leaning in with her titanic O cup breasts now covered up by a loose wrapping of bedsheets, raveled around her body like a toga. “God…you must be really tall now…” Holly bit her lip looking back at Tiffany’s titanic assets, nearly bursting out of her makeshift dress. “Yeah I only had one vial too…but I was pretty tall beforehand so maybe that's why I grew so big." She said smiling again as she got up from the couch leaning her head closely as she looked up at the gap between the top of her head and the ceiling, still towering over everything in the living room. "I haven't measured myself yet…but if I grow any taller I won't be able to fit inside…" She blushed immediately recalling her dream, thinking back to her incredible fantasized size, yearning to grow again. "I should really get going, how long was I out?"

She said sheepishly as she searched the room for her purse, opening it and looking for the vial. "Like…half an hour…I was really worried about you." Holly paused, realizing the vial was missing, immediately responding with intensity. "Where is it?" - "Hmm? What?" - "Don't play dumb with me, the vial, it's gone." - "Wait really? Oh no…" - "Seriously…I paid good money for that." - "Maybe…Howard took it because he was worried about you." Tiffany tilted her head, looking sorry for her as she sighed gently. "Ugh…now what am I going to bring back to the ladies…ugh and it's so late, I need to go home. I'll come back later. Thanks for taking care of me." - "Of course…" Tiffany blushed looking down at her smaller head bobbing under her giant breasts, passing beneath her her towering height, a foot and a half taller than her in comparison. "Have a great night, hope you feel better Holly!" She hugged her tightly, smashing her titanic breasts against her head, smothering her in her cleavage. She gasped for air as she looked forward to an ocean of beautiful breasts before craning her head all the way back to see her smile still covered up by the size of her chest. "Thanks, Tiffany. See you later." Holly grunted as she let go of her, letting her heels touch back onto the floor before she felt her tight and squishy body leave her smaller curvaceous frame. She turned looking back as Tiffany waved her off, leaving the front door as she followed behind her, stomping into the hardwood floor with her large feet.

She gently closed the door behind her, looking back at the door frame lining up to level with her chest half a foot below her head. She slowly began to grin devilishly as she felt a slight bulging in her incredible cleavage as she reached into her massive bust sliding out the last vial of growth serum, still filled to the brim with potent pink serum. "Mmm…hahaha…I'm already taller and way bustier than my little sister now…but another whole vial would make me grow so much bigger than her and everyone else…hahahahaha!" She laughed maniacally as her fingers finally plucked the vial out of her incredible bust with a sounding pop. "Mmph…I wonder how big I would get if I drank a second vial…hmm…" She slowly twisted the cap off the vial and took a whiff of the serum before moving it closer to her lips. She looked at the pink serum running through the glass as she toyed with the idea of drinking the rest, her other hand slowly circled her nipple, dancing around it as she started plot deviously.
