Denise, by contrast, was only thirty, also blonde, but with short, straight hair. She was athletic, and her body, while perfectly shapely,, was certainly not as jaw-dropping as Carly�s and her ass was a little bigger. Both of them worked admin for the same pharmaceuticals firm and, because of decisions made by a male manager who could not see past Carly�s pneumatic bosom to the thoroughly poisonous personality beneath, Carly was Denise�s boss.

The day began in a typical fashion. Denise was already at her desk when Carly walked (minced?) in. She wore a tight white blouse with a hint of cleavage that for a normal-breasted girl would have shown most of it off, and a short, clingy blue skirt, which barely covered her backside. Her legs were bare, despite it being autumn, and her feet were encased in impractical looking wedge-heeled sandals, black, at least, to show some willing about the office�s dress code. All eyes were on her as she bounced up to Denise�s desk:
�Have you finished that filing from yesterday?�

Denise sighed, �What filing?�
�I told you, we�re rearranging the customer accounts, we need it done today. All of it.�

Denise struggled to keep her calm, �I don�t think you did tell me.�

�I did, you obviously weren�t listening - you�ll have to do it all today - and don�t go home until you do.�

Fucking hell, and on a fucking friday as well, Denise wished she could just take Carly�s swan-like neck in her hands and... �Ok Carly, I�ll see what I can do.�

�Good, do it. I won�t be here for the rest of the day - I have a very important meeting with a supplier.� And with that, Carly left, male eyes tracking her undulating ass as it bounced its way through the office.

Ten hours later, Denise wanted to kill Carly more than she ever had before. This job would not be finished that day, or the next day, or the day after that. The files that needed rearranging were in a complete state, due to Carly�s �let someone else do it for me� style of command, and it was clear that the only reason she had tasked Denise with it was that the current system had become unworkable. Denise was alone in the office, under one tiny patch of light that she had left on, combined with the eerie glow of her computer screen. In the privacy of the deserted building, she had removed her jacket, opened her blouse and slipped off her high heels. She sighed for the millionth time and padded on her aching, pantyhose-clad feet to Carly�s desk. It turned out she couldn�t do anymore without access to Carly�s personal computer.
She turned it on. The desktop was a picture of Carly in a swimsuit. Christ but this woman loves herself, thought Denise, wonderingly. The files were easy enough to find and extract but, seeing as she was alone, and unlikely to be disturbed, an idea occurred to Denise. Carly might not have anything incriminating on her computer, but what if she did? Denise had to look.
The best place to check seemed to be Carly�s email. Most of it turned out to be the same boring stuff as Denise received all day everyday but one header did catch her eye - �Problems with Product -Help me!�. She clicked it. This opened an email conversation between Carly and someone called Richard that seemed to have occurred almost in real-time. Bored with work, and unsure if this would be more interesting, Denise had to read. She could not believe what she saw.

CARLY: OH MY GOD, my boobs feel so weird. This isn�t right!

RICHARD: Stay calm, weird how? What exactly is going on?

CARLY: I don�t know, the skin feels really tight and hot, and they itch.

RICHARD: Ok, what happened? Did you take an overdose?
CARLY: AN OVERDOSE!!? You can overdose on these things?

RICHARD: Of course, its a drug like any other. Did you take more than you should have?

CARLY: Maybe one more. I couldn�t remember if I�d taken one today. WILL THIS GO AWAY!!?

RICHARD: It should, what about the size, are they any bigger or smaller?

CARLY: I DON�T KNOW!!! They feel swollen, but I don�t think they are, they haven�t changed since you got me to this size.

RICHARD: Good, remember this is a highly volatile drug, it caused your breasts to grow very rapidly, failure to follow the proper dosage guidelines could result in them changing size again. You should be ok, but remember, this is definitely not FDA approved, don�t tell anyone.

Denise was stunned - this meant that Carly was a fake - not implants but some drug, and some drug that could cause her problems if used badly. The conversation was only a few days old, so she was definitely still on it, and it might be causing her worry. She wasn�t sure how she could use this information yet, just confronting Carly with it was just not her style, and anyway, a volatile rapid breast-growth drug sounded just slightly unbelievable - Carly would be able to laugh her off. Still, Denise was sure that this knowledge would come in handy. She shut down Carly�s computer, gathered her things, and went to her car.
Driving home she was struck by a wild notion. She needed more evidence, could she get it? Perhaps by going to Carly�s house? Would she be that bold? Yes, it turned out, her hatred of Carly was simply too much not to do anything. She changed direction and pulled into Carly�s road. None of the lights were on in her house, it was a Friday night after all, Carly must be out. Denise rang the bell anyway. Sure enough, no answer. Perhaps a window? None of the downstairs ones were unlocked, but an upstairs bathroom window had been carelessly left wide open, and it was next to a very sturdy looking tree.

This was madness, this was ridiculous, Denise couldn�t go climbing trees and breaking into her boss�s house in the dark. Then again, the prospect of destroying Carly was too much to pass up on - it wasn�t as though she hadn�t given her ample cause. Denise kicked off her shoes and, wondering at her own madness, began to climb the tree. It wasn�t too difficult, she prided herself on keeping fit and healthy, and her strength was more than equal to the task. She laddered her tights and slightly tore her skirt, but before long, she was in the window and searching for Carly�s light switch.
The bathroom was as unordered as Carly�s filing system, empty and used bottles of various hair and beauty products stood or lay scattered all over the room. There were at least five makeup bags filled with a bewildering array of lipstick, gloss, eyeliner, and anything else you could imagine, as well as some things you couldn�t. Denise wasn�t against using all this stuff, but there was so MUCH! The pills, however, much to her irritation, weren�t here. They�re a very private thing, and illegal too, she thought , perhaps the bedroom.
Slowly, carefully, she opened the bathroom door and found the room that Carly slept in. It wasn�t difficult - the door was already open and everything was pink. The room itself was huge, and covered in discarded clothes and shoes. An enormous walk-in wardrobe and double-bed dominated the scene. On the bedside table, however, Denise found an unmarked white plastic medicine bottle. It was half full of non-descript white pills, like tic-tacs. She poured herself a few, actually considered trying them out for a second, shook herself, then figured that with this evidence it was time to leave.
It was then that she heard a car screech to a halt outside. Headlights flashed through the net curtains and the front door banged. SHIT! She�s home early! Panicked, Denise lunged for the walk-in wardrobe and shut the door as heavy, thumping, high-heeled footsteps sprinted up the stairs. She could hear Carly whimpering and muttering to herself as she charged into the room, not even noticing the light had been left on.
�Oh God, oh God, its happening again, I need more, I need more.� she kept repeating over and over, in a panicked voice. Through the slats in the wardrobe door, Denise could see Carly - she was a state. Her hair was wild and she had torn open her top and unhooked her bra. Her massive, perfect breasts, hung free, bouncing all over the place as Carly paced up and down. Taking the medicine bottle she poured herself a handful of pills and swallowed them, dry, with raw, hungry gulps. She gasped, dropped the bottle, and started kneading her breasts in relief. �There you go, there you are, you don�t hurt anymore.... Oh God, Oh God that�s so good....� Denise watched, amazed and slightly appalled, as Carly transferred one hand from her chest to between her legs, writhing this way and that as she plumbed her snatch uncontrollably. She panted and shrieked like a woman possessed as she masturbated, still completely unaware of Denise�s presence. Clearly these pills had some very interesting side-effects. Denise gripped her handful tighter. Eventually Carly�s uncontrollable horniness seemed to subside and she sank back on the bed, more or less fully clothed. Another ten minutes crouched anxiously in the dark and Carly�s breathing had become very heavy and rhythmic. The combination of pills and alcohol had knocked her out cold. Slowly, carefully, Denise opened the wardrobe door and tiptoed out.

Carly really was out for the count. Her face was hidden in the mess of her hair, and one hand still rested on her left breast, squeezing and playing with it, even in sleep. She made little mewling noises, and Denise could smell the sweat and sex on the air. Christ, she thought, if she knew I�d seen her like this... She left, quickly.
Carly had left the front door unlocked and would seemingly not be easily woken, so Denise�s exit was considerably more dignified than her arboreal ingress. She hid the pills in a tissue, put them in her handbag, and drove home.

It was Monday morning and Denise was still not sure what to do about Carly. On one hand, she still hated the bitch for how she treated her and what she made her do. She was delighted that at least some of Carly�s ridiculous genetic good fortune had been obtained through artificial means and she knew that she had to do something about her, but she still had no idea what. And then there was her other problem: the temptation to try the pills out was a surprisingly strong one. Denise had always considered herself happy with her body and a fairly balanced individual, but still, her B-cups, while a nice shape, could certainly be bigger, and she did occasionally wear a push-up bra. Was this really any different? She stared long and hard at the pill, pinched between thumb and forefinger - it looked innocuous enough.
Eventually the more sensible part of her won out: of course its fucking different, you idiot, do you want to end up like Carly? So obsessed with your own tits you get hooked on these things? She hurriedly wrapped the tablet up in its tissue-paper again, tucked it in her jacket pocket and started the car.

Carly was, amazingly, already in the office when Denise arrived. She was dressed even more outrageously than usual, a white t-shirt with a huge hole for her cleavage, which bulged from an entirely inadequate bra, very brief and tight denim shorts, and high-heeled sandals with platforms. She was definitely violating the office dress-code, but their manager, Roger, was male and straight, and Denise doubted very much that he�d say anything. Rumour had it that whenever her work slacked and Roger noticed, Carly bought him off with a tit-wank. Denise would not have put it past her.
Denise spent the morning (like most of the men) watching Carly. Eventually she spotted it. Carly took one of the pills whenever she went to the water-cooler, which was surprisingly often. She was quick and subtle about it, but Denise was deliberately paying attention. Now what could she do? The reaction was fast and seemingly quite violent. Obviously the frequency with which she popped the pills kept Carly�s tits as she wanted them, but what if she were to take more than she meant to...

Coffee was the solution. Carly chose that moment to call Denise over and ask her to fetch her some coffee from the machine. Normally Denise would have told her to go to hell, since it wasn�t in any way part of her job description, but today she went without complaining, pausing only to drop four of the eight pills she had swiped into the hot brown liquid. She felt a little pang, not knowing what it would do, but she knew Carly wouldn�t get badly sick, as she had seen her take more than that before she frigged herself silly on the Friday night. Something would probably happen though.

Something did. Something big. Carly drank the coffee as normal, wrinkling her perfect button nose a little at the unexpected taste the pills at lent it. Denise was at her desk, watching her carefully. After a while, Carly arched her back a little in discomfort, and scratched at her tits when she thought no-one was looking. Denise leaned forward, her work forgotten, watching.
Carly was breathing very heavily. One or two of the men in the office appeared to have noticed now and eyes were swivelling in her direction. Suddenly she coughed, swore, clutched one hand across her breasts and sprinted awkwardly on her ridiculous heels to the bathroom.

Denise was torn. She really wanted to find out what was going to happen, and maybe to confront Carly, maybe even to help her, if she was in real distress. But she was also worried about what she might find, at how angry Carly might be. Still, she had to do something.

Carly was whimpering as she entered the bathroom. She wasn�t in a cubicle, she hadn�t made it that far. She knelt face down, her huge tits mashed underneath her, panting and fingering herself with her back to Denise.

�Carly, are you all right?�

�What.... ooo... do... you.... aaah.... care?�

�I care ok, you looked sick, just tell me. What are you doing?�
�I can�t.... errk... I can�t...oooooh.... I can�t stop.�

�You can�t stop?�

�Mas.... mastur....�
Denise whistled in awe - not the most tactful reaction, but then she did still dislike Carly. �Ok I get the picture. Look, you�ve got to try, you can�t stay in here forever.�
�I.... know... but.... ooo.... I.... they hurt! My.... my....�
Denise had a pretty good idea what was coming....

Carly suddenly flipped herself completely over, her fingers still lodged deep inside her obviously damp shorts and kneading back and forth. Her enormous breasts were free of the bra and jiggled all over the place. �MY TITS! MY TITS are hurting!� and she gasped, a long, breathy sound.... �this... this makes them.... arrr.... a bit.... better.�
Denise thought it was as good a time as any: �The pills.�
�You... know....?�
�Yes, your email, you left it open.� A white lie, but in her state, Carly probably wouldn�t call her on it. �They aren�t safe are they?�

�Don�t.... know. Took too.... many.....�

�How many, when? Should I ring a doctor?�
�No.... no.... not...� She broke off to dig harder into her dripping cunt. �Not... legal.... I took too many on.... friday.... should have.... oooooooooHHHH GOOOOODD!!!! worn off... by.... now.�
Denise whistled again, standing well back, out of the way. �You should know, I gave you some more, just now, in your coffee... I think that�s why this is happening.�
Carly managed to pull herself together just long enough to stare at her in shock. �You bitch! How could you? How many!?�
�Four.�

�Four... arrr...... four.... is.... fuck, fuck me.... four is.... far... too..... CHRIST! many.�
Denise stepped a little closer, �What do you want me to do?�

�FUCK OFF!� yelled Carly, followed by a long, part-tortured, partly erotic moan.

�Ok, but, apart from that, is there a cure?�

�NOOOOO!!!! There�s no fucking cure. I�ve never had this many, I don�t know what�s going to happen, but my tits ache, they really ache, and this.... this..... its not helping anymore.� She withdrew her moistened fingers and looked at them stupidly. �I can�t stop it.�

Denise watched, fascinated as Carly�s milky-white breasts seemed to move of their own accord. What the hell? Then she realised, they were actually growing fast enough to see!

�What!? What are you staring at?�
�Your... your...� the pink nipples, already hard, stiffened even more, elongating and thrusting outwards. Faint stretch marks began to appear in a web all over the mounds as they swelled from within.

�My what? My tits hurt, yes, my tits,.... oh God.... they�re growing.�

�Did the pills do this before?�

�NO! No they didn�t, I already had big tits, they just toned and raised them a bit, half a cup-size maybe, over a week or two... not like this..., Oh they�re so big....�

They were. As the two women watched, Carly�s breasts swelled and tightened, the nipples raising themselves to point ever higher and higher, even as they seemed to strain to escape the chest that bore them, so pointed they had become.

Carly was weeping, her head buried in her now enormous valley of growing cleavage. �Oh.... my boobs, my poor boobs.... why won�t they stop?..... my poor little boobies.� She now resembled some of the huge breasted implant queens that Denise had seen once or twice on talk shows. �Oh.... oh no.�

Carly, with great effort, flipped herself over again so she was kneeling. Her nipples dragged along the ground and she could barely manage the effort to keep her massive chest from pulling her flat on her face. �Oh no.�

�What�s wrong?� said Denise, feeling faintly stupid.�

�Its my.... ooooooohhhhhhh nooooooooo!!!!!� Both of Carly�s hands went to her butt and she fell heavily onto her beanbag like chest. There was no doubt about it - the seams of Carly�s super-clingy shorts were fraying, and rapidly. The material was going from too tight to be comfortable to too tight for proper blood flow.

�Please help me Denise.� Carly whimpered. �Help me, I can�t deal with this... my.... my butt...� Before Denise�s eyes the shorts stretched and split, falling away to display Carly�s creamy bulging butt. Like her tits it had always been big, but it was much much bigger now, vast even, and it was still growing too. �Oh God.� Carly breathed, �I�m a total freak show. My arse is so huge.... my beautiful body.... its ruined. RUINED!� and she took to sobbing again.

Denise felt that something had to be done. Carly couldn�t remain here in this state, but there was no way to cover her now colossal chest and her butt, which had now become like two fleshy beachballs jostling for position. �Do you want to leave?�

�Leave!? I want to die! Look at me! I�m like some freak�s fantasy woman!�

Denise looked around - the bathroom did have an emergency exit onto a fire escape, which would at least mean Carly wouldn�t be seen in the office, although she wasn�t sure what they�d do once they got outside.

�It�s all so TIGHT!� Carly shouted, rubbing her hands uselessly over her tits and arse, �I�m filling with something, fat, fluid, water, I don�t know! I can�t.... my skin can�t....�

Without saying anything, Denise offered her a hand up. It was as much as the two of them could do to get the rapidly expanding blonde on her feet. Her high heels nearly slid from under her, but she managed to stay upright, moaning and cursing at the pain in her muscles from the increased weight. �Denise its... spreading.... I.... the itching is all over.�

Denise watched as Carly began to thicken in other places. She wasn�t becoming fat, just even more curvy. Her previously taut stomach became a gentle curve. Her flanks filled out a little, although nothing that would make her ridiculous hour-glass shape appear more normal. Her stunning legs became a bit curvier and her rather bony feet filled out, making her squeak with surprise as the straps on her sandals broke and she stepped barefooted onto the cold tiles. Carly was now completely naked, and there was now a lot more of her to be naked.
�Ok, we�re going to get you outside. Are you still....� Denise couldn�t believe she was saying this. �Are you still growing?�

�Yes,.... I think so.... I�m so fucking big its hard to tell. Not as quickly though.�

�Can you walk?�

�Maybe, if you help.... fuck.... I feel so fucking horny!�
�What!?� That was the last thing Denise was expecting.

�You know, horny! These boobs are alive! I�m getting all kinds of.... oooo..... sensations..... oh.... sweet Jesus....�
Denise�s eyes widened a Carly�s sentence broke off into satisfied moaning. Her breasts were now so sensitive that just brushing them could make her come. Another complication to their plight. She was just grateful for now that the bathroom was down a long corridor, no-one would have heard Carly�s cries and no-one appeared to need the toilet for now, but that wouldn�t last for long. �We have to get you out of there.�

Carly appeared to have calmed down for the moment. Torn as she was between horror at the disastrous proportions her body had reached and ecstasy at the waves of pleasure coursing through her she still managed to pull herself together for long enough to drop a bombshell: �Have you noticed the.... owwww..... effects yet?�

�Effects?� asked Denise, perplexed.

�Of course, after you stole my pills you had to be punished, I think I�ve managed to....aaaawww.... give you at least ten pills today. In.... ouch.... in your lunch and.... fuuuuuucck.... your coffee.�

Denise couldn�t believe it, �You knew.�

�Yep, I saw your car in my road when I came home the other.... huff...errk.... night, and your crappy boring shoes underneath the tree. And, as you obviously saw, I�m hopelessly addicted to these pills, obviously I noticed some missing. So, feel anything?�

Damnit, balls, fuck and damn! Carly hadn�t been as wasted as she�d appeared. Obviously she�d needed the pills more than she�d wanted to confront Denise, but she�d still noticed.... Did she feel anything? Instinctively her hand went to her chest, but her breasts felt the same as ever, perhaps she was immune.

She wasn�t. Trying to push Carly�s bloated tits towards the fire exit Denise was suddenly aware of a horrifyingly new sensation in her rear end. Oh shit! Her arse was definitely not somewhere that needed any extra padding. She�d always been a little unhappy with it, as it was. No doubt about it, her panties were becoming very uncomfortable as the flesh shifted around, burying themselves deep into her pussy and giving her a terrible wedgie. She felt the nylon of her pantyhose stretch and scrape against her skin as she expanded. It tickled her already sensitive butt-cheeks and then tore. Her tights were ruined and now her skirt began its all too rapid ascent up her inflating backside. This wasn�t fair, this wasn�t fair at all! Bigger tits, Denise could have handled, but now she was just going to have the fattest arse in the world! Unbidden, tears began to roll down her cheeks.

Carly had been watching with amusement, but eventually she grew tired of Denise�s distress and went back to pleasuring herself, gasping as her jelly-like tit and arse flesh quivered in time with her orgasms.

Denise was feeling something similar but trying desperately to lock it down. She couldn�t deal with being the only girl in the world who came when you slapped her arse, especially when her arse was the size of two sofa cushions.
�No tits dear?� Asked Carly, maliciously, between frantic digs at her snatch. She was so caught up in the sensations of it all, that the fact that she had turned into a ridiculous porn-star caricature of a blonde bimbo appeared not to matter to her anymore. All she cared about was pleasuring herself and seeing Denise in trouble.

�No... no... they�re....� the skirt rubbed against Denise�s ballooning buttocks and she stifled a gasp, �something�s happening there toooooo!!!!� It did, but ten pills in one day meant that it happened in an even more dramatic fashion. Denise�s chest appeared to explode. Whatever was filling her tits rushed into them so fast it almost knocked her on her overgrown butt. Her jacket and blouse were torn open, buttons ricocheting off walls and ceiling. It happened so fast that gravity almost hadn�t time to take effect - the visual was that of two pointy flesh torpedoes, each fully a metre and a half long, surging straight out from the panting woman�s chest, before they collapsed, becoming immensely engorged teardrops pulling her towards the floor. �Oh my fucking Christ.... I can�t go on.� Denise panted and moaned, rubbing her stretch-mark covered new assets as they throbbed and itched and ached and OH how she LONGED to just play with them forever and ever....

No, she couldn�t become like Carly, writhing in a mess of her own sweat and juices, she had to focus. This was a medical problem, she needed a hospital - they�d deal with it, at the very least with surgery after the effect stopped. Unless... unless it never did. Denise bit her lip - she couldn�t allow herself to worry about that right now.

She shuffled, almost bent double, towards the exit. No, this wouldn�t work, she wouldn�t do it like this. She kicked off her heels... better, better grip. Ok, keep.... it.... together. She looked in the mirror. It was at head height, she couldn�t see all her new flesh. Still her, same pretty face, same tasteful makeup, same hair. She could come out of this ok... as long as she just.... oh no.... did she really just see that?

�Carly.�

�.....oh God.... what.... fuck.... do you.... shit that�s good.... what do you.... want?�

�What other effects does this have?�

�Don�t.... know.... you OD�d big-time, you stupid bitch.�

Denise was tempted to hit her, but she could barely move, and was too fascinated with what she was seeing. Surely not.... surely.... not her face! But it was changing. Subtly at first, but it was. It seemed as though her boobs and butt had stopped, now each breast and each buttock was the size of a very tight and inflated beach ball, now all the energy seemed to go into this new transformation.

Her hair began to lengthen, and became wavier - looking more like an imitation of Carly�s. Her cheeks gained a little chub, her nose shrank until she could barely breathe. And then, worst of all, her lips began to fatten. All too quickly they reddened, grew thicker and poutier. They lost their normal cute shape, beginning to resemble the sausage like appendages that resulted from too much collagen. Cock-sucking lips said Denise to herself, despairingly, not good for anything else.

Suddenly, pain shot up her calves and thighs, starting at her feet. Her heels raised themselves off the ground. Shocked, Denise realised what had happened - her body had adapted itself to only wearing high heels. She managed to shuffle her immense bulk to where her shoes lay and somehow get them on. They were heels, but not really tall enough, her feet were still badly cramped. Nothing else she could do though. She had to escape, get help. But first she had to get past Carly.

It wasn�t going to happen. The other woman lay there, industriously ploughing herself, right in Denise�s determined but unsteady path. Denise tried to step over her, herself constantly shaking from almost coming as her tits rubbed together and her buttocks jiggled. She hefted her enormous boobs in her arms and trusted her arse to stay out of the way, but it was no good. A foot caught Carly�s expanded form and she tripped, landing on top of the recumbent woman.

It was too much for both of them. The shock of the impact, the vast and vastly more sensitive expanses of flesh hitting each other. Both came together, with a ferocious intensity. Denise found herself with her grotesquely bloated lips hovering above a beer-can sized nipple and found nothing could stop her from clamping onto it as well as she could, rubbing her tender new reshaped mouth over the stiff, dark skin, and making Carly moan with delight. For her part she felt Carly try to grab the wobbling flesh of her enormous butt-cheeks as widely as possible, digging her nails in so the pleasure almost hurt her. It was bliss.

They writhed together, exploring each other�s cartoonish, sex-built, new forms for a long, long time. Eventually, Denise sagged sideways off of Carly with a sigh and said �What are we going to do now?�

�I�ve got a few ideas.�

�Yes, so have I, but its the pills talking. I meant apart from that.�

�No idea, can you move?�
�Not really. Not without coming everywhere again, and I�m so heavy now.�

�Me too... I guess someone will find us eventually...�

�I guess so.... until then, we don�t want to get bored.�

�No.�

They started again, it wasn�t really so much a choice as a calling, the pills had remodelled their bodies, hard-wired them for sex, and at least, for now, while the effects lasted, they could enjoy it.
