Caution: This story contains themes of naughtiness not appropriate, well, for anyone really, but assuming you weren't looking for a great work of literature in the first place and were kind of in the market for something with science run amok and breasts expanding in an unabashedly sexual fashion and all that that implies, well, you might as well just keep on reading, since you're already here and all that.

Filling Up Petra

by: Kodos

����������� Petra sat waiting on the table in the examination room.� The white paper stretched across the bed crinkled against her snug jeans every time moved, jarringly loud in the otherwise silent room, while the fluorescent lights lent a wan, bluish cast to her complexion that she thought made her look even paler than she already was.� She shivered.

����������� Dammit, isn't it enough that they keep me waiting here for half an hour without having the thermostat set at frigid? She thought, you'd think for how much money this place is taking in that they could hire an extra nurse or two to look after their patients.� If I had known it was going to take this long I would have left my shirt on.

����������� Even so, Petra made no move to retrieve the baggy sweatshirt that lay where she had thrown it when she first entered, in a shapeless heap on a chair by the door.� Her bright blue hair, one of the few perks of working at the museum, barely brushed her shoulders, while the harsh light shone down on her modestly slender figure; hips that flared out gently from her waist, and only the slightest hint of chubbiness around her middle, thank to several months keeping to a punishing workout regimen.� In fact, there was just one thing about her figure that was in any way remarkable, well, two things really, and they were both threatening to spill out of her gargantuan red bra, its straps frayed by the vast demands put upon them.�

����������� Why did it have to be my tits?� Petra sighed as she glanced despairingly down at the barely-contained tide of tender, tremulous flesh that threatened to lap over the cups of her custom-made brassiere, Couldn't I just have a normal body for once in my life?� I mean, when I was big all over my boobs were, like, the one part of me I actually liked, but now they make me look like a freak.� And that's when I've got a top on.� Come on, where the hell is that doctor?

����������� As if on cue there was a perfunctory knock at the door before it opened, not leaving enough time for Petra to have objected even if she had wanted to.� The doctor came in, engrossed in the notes on her clipboard, confirming Petra's every suspicion at a glance of what a female plastic surgeon would look like.� It was impossible to tell if she was twenty five or fifty; her face was without a single line or wrinkle, and Petra found herself at a loss to figure out just what was the result of well-applied makeup and what was because of considerably more invasive procedures.� The heels the doctor wore served to make her seem even leggier than she naturally was, and her full, perky breasts were more than large enough to leave no doubt that she had had more than a few dozen cc's of something pumped into her figure.� She looked up from her notes, her eyes bright and clever behind a pair of dark-rimmed glasses and gave Petra a polite but professional smile.

����������� �Ah, Ms. Jennings, so sorry to keep you waiting,� she began, �Allow me to introduce myself; I'm Doctor Bloom, and I've been reviewing your case in some depth; it says here you've come in because you're interested in a reduction.�

����������� �Yes Doctor,� Petra said, fidgeting nervously where she sat, �I just- I can't keep on living like this, and I'm getting desperate to find someone who can help me.�

����������� �Why don't you start by telling me how long you've had this problem?� Doctor Bloom began, pulling up a chair and settling into it, leaving Petra with the distinct impression that she had seated herself at a level where she was perfectly positioned to stare at her patient's chest.

����������� �Well, it's like this,� Petra said, feeling terribly self-conscious as she tried to get the doctor to make eye contact with her, �I used to be fat.� Like, not just kind of on the chubby side of things fat, or I had to shop at stores that have the word �woman� in their name; I was really fat, like I tipped the scales at four hundred and fifty pounds fat.� Now, I was as big all over as you'd probably think, but my boobs were just enormous.� Like, walking around with a pair of beach balls stuffed under my shirt big.� Even with a belly that stuck out so far I could barely fit behind the wheel of an SUV, my boobs just stuck right out in front of me like a pair of weather balloons.� I've always been a big eater and not exactly a huge fan of exercise, but when I started pushing a quarter of a ton, I decided to make some changes; start taking better care of my health, you know, maybe even get myself to the point where just leading tours around the art museum didn't leave me short of breath and where, just maybe, I'd finally be able to go out on a date like a normal girl for once instead of just attracting freaks and weirdoes.�

����������� �And what did you do?� Doctor Bloom asked with clinical curiosity, pulling her eyes away from Petra's chest to jot down a few notes.

����������� �I just decided to change,� Petra explained, still eyeing the doctor doubtfully, �I went on a brutal diet, started walking to work from my place in the Fan District, anything I could do to cut down on calories and every excuse to get up off the couch and be active, and it worked; just under a year after I started I was down to one fifty.� I could climb a flight of stairs without feeling like I was going to pass out; I could buy my pants off the rack instead of having to order them custom.� Everything was just like I had hoped it would be- except for well, you know.�

����������� �Assume I don't know,� Doctor Bloom said, �I want to hear it from you and not the nurse's report.�

����������� �Okay, well, losing three hundred pounds that fast can take a toll on your body, though I bet you don't need me to tell you that,� Petra said, �And in a lot of ways I was lucky; I didn't end up with belly flab all the way to my knees, or saddlebags or cellulite, and aside from the fact that I've got a bit more padding around the middle than a girl my size ought to, you'd never know that I used to be three times the woman I am now.� Except for, you know, my boobs.�

����������� �Yes, why don't you tell me about your breasts?� Doctor Bloom said, making Petra wonder for a moment if she was a plastic surgeon or some kind of psychiatrist.

����������� �Well, like I said, everything else just kind of slimmed down perfectly, �Petra said, �I mean, I barely even had any stretch marks, and I used to have an ass twice as wide as my shoulders!� My boobs though, I dunno; it's like I used up all my good luck everywhere else and instead of getting smaller when I lost weight, they just kind of deflated.�

����������� �Deflated?� came the doctor's echo.

����������� �Yeah, you know, like a couple of balloons that have been blown up until they're ready to pop and then have all the air let out of them,� Petra explained, �They don't weigh any more than they did before, I'm sure they're actually, like fifty pounds lighter, and of course they're not really, you know, bigger, they're just really stretched out and depressing.� That's what happened to my boobs.� I mean, I know that while I've got a bra on they still look pretty juicy, and I'm not expected that a pair like this are just going to hold themselves up like when I had a huge belly underneath for support, but the way they are now, I just can't deal with it anymore.�

����������� �Ms. Jennings, I don't want to make you feel at all uncomfortable here,� Doctor Bloom began, �But perhaps it would help if you just went ahead and showed me the problem.�

����������� �Well, okay doc,� Petra sighed as she reached behind her back and started to unfasten the dozen hooks that held her bosom in check, �Just try not to be too weirded out, okay?�

����������� As the last clasp surrendered to Petra's practiced touch, her breasts slipped free from their constraints.� With a heavy, flaccid slap, they fell against her stomach, stinging slightly as they flopped out.� Though their skin was smooth and supple, that was about all that Petra could say in favor of them.� They each hung so low that they rested shapelessly in her lap.� They were wide enough to cover most of Petra's slender front, though gravity and her recent weight loss had left them so stretched out that they only met each other at her navel.� Wide and long as they were, each was barely an inch thick, save for where they pooled limply on top of her thighs, her nipples, once proud and plump, now chafing against the denim of Petra's jeans,� buried under the mass of loose-hanging flesh above them.

����������� �Oh- Oh, my,� the Doctor Bloom managed, the sight of Petra's pendulous bosom leaving even as seasoned a surgeon as herself speechless for a moment, �I'm sorry- I, well, I don't believe I've ever seen a case like this in a woman as young as you before, Ms., Jennings.�

����������� �I know, they're awful, aren't they?� Petra lamented, giving a shrug that set her twin masses quivering weakly, �I can't have big fat tits like when I was huge and I can't even have small ones like a skinny girl; it's like I've got the worst of all possible worlds!� Girls look at me all catty because they see me out on the street and think I've got like, these killer tits, but I can't even get to second base with a guy without letting these, these things flop out like a couple of tube socks full of jello.� Please doctor; tell me you can something to help me out here.�

����������� �Well, we have a very good track record at this clinic concerning this kind of work,� Doctor Bloom began, regaining her composure and eyeing Petra's pendulous bust once again with an analytical eye, �Your, er, options, however, are going to depend on exactly what kind of outcome you're hoping for.� You don't mind, um, if I examine you a bit more closely, do you?�

����������� �Go right ahead, you're not going to do any damage that my genes haven't done to me already,� Petra said nonchalantly, still tensing up a little as the doctor's deft hands kneaded and explored her breasts, �As for what I want, well, I guess what I'd really like is for them to be just small enough that they don't look too freakish on me now that I'm all skinny, but full and plump enough that I still feel sexy without a shirt on.�

����������� �Hmm, that's a tall order, Ms. Jennings,� the doctor said pensively, even as she hefted one of Petra's breasts as if it were some kind of alien lifeform she had just discovered and was carefully examining, �We do get a fair number of women coming in for simple reductions, whether due to age, or weight loss, or unpleasant side effects after pregnancy, so giving you a bustline more in keeping with the rest of your figure wouldn't be all that difficult.� And plenty of women come in here for a bit of a lift too, no major reshaping, just a quick turn under the knife to leave everything riding a little bit higher than before.� Doing both those things, especially in a case as acute as yours though, that would test even my surgical skill.� I suppose implants are out of the question?�

����������� �What? No, I don't want a bunch of plastic crammed into my tits; I want them to still all be me, just a bit smaller and a lot firmer!� Petra answered, before noticing the doctor's wry smile at her sudden outburst, �I mean, no offense about the implants; I just, I just kind of wish I could have my old boobs back and still be as fit as I am now.� Isn't there any way you can to that?�

����������� �I'm sorry, Ms. Jennings, I'm afraid not,� Doctor Bloom admitted with a rueful shake of her head, �Even making the most of what we have to work with here would be, challenging, to say the least.� And such miracles do not come cheaply, if they come at all.�

����������� �Okay, how much are we talking about then?� Petra asked, �I've been saving up a bit; I'm willing to pay for good work.�

����������� �Well, as I said Ms. Jennings, to simply reduce your, erm, assets to a more reasonable size would be an easy enough matter, doable for perhaps as little as five thousand dollars,� the doctor began sighing at Petra's suddenly hopeful expression, �But to accomplish something beyond just reducing the nature of your problem here, even if it were possible, and I can't be at all certain it is without a much more thorough examination, would likely cost fully fifty thousand at the bare minimum.�

����������� �What, why so much?� Petra asked, taken aback at such an inflated price, �There's just no way I can afford that.�

����������� �I know- I'm sorry,� Doctor Bloom said, patting Petra's knee comfortingly, �You have to understand it's not simply a matter of making money for us though.� Handling a procedure of this magnitude would call for several of our most experienced surgeons, countless hours of planning, and even then, I couldn't in good conscience promise that you would be entirely pleased with the final results.�

����������� �What am I supposed to do then?� Petra asked again, a note of despair creeping into her voice, �Pay you five grand to hack my tits down to A-cups or just resign myself to going through life with a pair of boobs so stretched out that I can't walk around my apartment topless without them slapping against my thighs until they're all red and sore?� What kind of choice is that?�

����������� �Ms. Jennings,� the doctor began again, clearly doing everything she could to pour on the empathy, �Am I right in assuming that you are not exactly overburdened by an excess of wealth?�

����������� �Are you kidding?� Petra came back, �Twenty hours a week at the fine arts museum is hardly enough to pay the bills, let alone this kind of thing; of course I'm on a tight budget.�

����������� �Well, then, I may have another option that might suit both of our needs,� Doctor Bloom said tentatively, �In fact, if you're not averse to a treatment that's slightly more, well, experimental, you might even emerge from your present situation more financially secure than you are right now.�

����������� �I'm listening,� Petra said attentively.

����������� �Really?� Oh, but this could turn out so wonderfully for both of us,� Doctor Bloom said brightly, as if surprised by Petra's ready agreement, �Okay, how much do you know about biology, how the human body works and all that?�

����������� �Not much,� Petra admitted, �Art major, remember?�

����������� �Alright then, I'll try to keep it simple,� the doctor said with just a hint of resignation, �So, here's the thing, your body is made up of billions of cells, each with their own special purpose, including fat cells.� Now, you might think that when you lose weight, especially a lot of it, that you lose fat cells, that your body burns them off somehow, but that isn't how it works at all.�

����������� �Then why am I three hundred pounds lighter than I was this time last year?� Petra asked skeptically.

����������� �Because,� Doctor Bloom began, her enthusiasm rising to a subject she had such a passion for, �Fat cells don't really go away; the total number of them in your body is pretty much set by the time you're an adult.� They're like little water balloons inside your body, you see?� When you start consuming more calories than you're using up, the fat cells in your body just swell right up to store the excess, even to several times their original size.� It's quite miraculous really, and we've developed a serum that accelerates this process, making it possible to re-fill the fat cells in a woman's body at an almost unbelievable rate.�

����������� �How does that help me then?� Petra asked, clearly unimpressed, �If I wanted to blimp out again I could just order a couple dozen pizzas and do what comes naturally; I don't need science to make me fatter even faster.�

����������� �Ah, but that's where our second breakthrough comes in,� the doctor explained, �You see, I have discovered a mix of hormones that hyper-stimulates the fat cells in a particular part of a woman's body, making them hundreds of times more receptive to expansion.� In short, with the judicious use of certain injections, I can now cause you to gain weight in any particular part of your body that you might desire, especially places that you have, or used to have, a lot of fat.�

����������� �Wait,� Petra said, finally catching the surgeon's meaning, �So you mean you could just make my boobs bigger again?�

����������� �Exactly,� Doctor Bloom smiled, perhaps a bit too triumphantly, �I have the means to fatten your breasts up until they're every inch as large as they were before you went on your diet.�

����������� �Hang on, and assuming I believe you� Petra said skeptically, �If just going under the knife is going to set me back fifty grand, what makes you think I can pay for whatever miracle treatment you've whipped up?�

����������� �Well, Ms. Jennings, the thing is that my treatment is so new and admittedly untested that what I need even more than money is good experimental data,� Doctor Bloom explained, �I've got the formula down, and I'm getting so close on the dosage, but the results right now are just unpredictable enough that I couldn't possibly get the foundation I work for to approve the treatment for general use.� You, however, present a particularly promising opportunity.� The magnitude of your, erm, situation, means that a successful trial on you would give me more than enough data to move forwards with the process, and for your cooperation my organization would be only too delighted to offer you this procedure at no cost.�

����������� �Wait, so other than the fact that my boobs hang down past my waist makes me so special?� Petra asked, still far from convinced.

����������� �Several things, Ms. Jennings,� Doctor Bloom said, �For one, the sheer amount of weight you lost means that your breasts, even in their present, uninspiring state, are absolutely brimming with fat cells, just waiting to be expanded once more to their fullest potential.� Secondly, the fact that you give every indication of missing having a pair of breasts so large you can't even wrap your arms around them.� Most of our prospective customers are women who have just lost a little fullness and are more than happy to leave here feeling perky again, especially if it means they get to pick up a cup size or two.� Finally, the fact that you are apparently willing to leave this clinic with a figure that would make most strippers blush means that you offer a unique chance for me to test my procedures to their absolute limits.� You can't imagine how valuable the results of a successful trial on your case would be to me.�

����������� �So, you're going to give me a huge rack again, for free, just because it'll help you with your mad scientist project?� Petra asked, staring down at her breasts, doubtful that her massive yet unimpressive bosom could be that interesting to anyone, �What's the catch?�

����������� Doctor Bloom looked decidedly nervous at this question, glancing between her notes and Petra as if she was trying to figure out whether telling the truth or glossing over it was a better bet.� She met her patient's gaze and spoke plainly.

����������� �Ms. Jennings, the fact is that the dosage and the variation in the ways that various subjects react to it has been causing me no end of worry,� she said, �Can you imagine what would happen if some middle-aged housewife came in for a bit of a lift and a pair of DDs and left here spilling out of a G-cup?� I'd lose my practice before the end of the week!� The fact that you're not only willing, but eager to walk out of here with a pair of absolutely enormous breasts means that your case is of incalculable value.� In fact, if you consent to endure an entire round of my experimental treatment, my backers will gladly pay you fifty thousand dollars.� How does that strike you?�

����������� �Hang on, hang on, what if something goes wrong?� Petra demanded, stunned by such a suspiciously generous offer.

����������� �Well, on one hand, the treatment might not be as effective as I've theorized,� Doctor Bloom elaborated patiently, �In which case you'd leave here with your bust increased considerably, but not quite to its previous grandeur.� You'd still need some serious support to hold yourself up, but you'd be a lot more fullness and shape up front than you have now.� On the other hand, and I think this is more likely, your body might be especially susceptible to the treatment, in which case you might well end up with breasts significantly larger than you had before.�

����������� �Significantly larger?� Petra echoed, glancing down again and remembering how unwieldy her boobs had been before she slimmed down.

����������� �Well, not so enormous you wouldn't be able to fit through doors anymore or anything like that, probably,� Doctor Bloom hastily assured her, �Just don't be surprised if you need to be fitted for bras several cup sizes in excess of what you were accustomed to at your peak weight before.�

����������� Oh, but she's a smooth one, Petra thought to herself, Offering me just want I want.� And how can I pass up that much money?� Even if something goes wrong I'm sure to come out ahead of where I am now, standing around the art gallery with tits like a pair of� punctured balloons dangling off my chest.� Even if I don't end up as big as I was before, it'd still be a hell of an improvement and for all I know, I could end up even bigger!� I know I should be freaked out by that, but just thinking about having a pair of tits that huge on my skinny little figure now makes me all hot.� Jeez, I know I'm going to regret it, but I just can't pass this up.

����������� �Okay,� Petra agreed, �I'll do it.�

����������� �Marvelous, Ms. Jennings, I hoped you'd come around and I'm sure you'll be pleased with the results, �Doctor Bloom smiled, �I'll just need you to sign a few waivers here, and then just give me a half hour or so to get you prepped and prepare the injections...�

�����������

�����������

�����������

����������� Soon thereafter Petra found herself escorted to another room, a windowless chamber done in unremittingly clinical white.� She was now naked except for a pair of red panties, and her body bore the clear signs of Doctor Bloom's handiwork.� Several small needles had been pushed into the soft flesh of her breasts and then taped firmly in place, each one attached to a thin tube filled with a viscous, milky fluid, running to a cluster of IV bags hanging nearby.� These had been strategically placed, Doctor Bloom had told her, to ensure an optimal shape for soon-to-be-growing assets.� Though the doctor hadn't done anything to numb Petra's breasts, the needles going in hadn't really hurt, just sort of pinched, her skin still feeling strangely tight around the injection sites.

����������� Petra had some kind of cuff wrapped around her right arm, as well, from which two more small tubes threaded their ways up to the array of bags.� A third tube running from it looked positively huge by comparison, fully half an inch in diameter and running from her arm to a large, surgical steel tank on a table nearby, featureless except for the computer on the front that controlled her dosage.

����������� Just how much stuff are they going to pump into me? Petra worried, Just the IV bags look like they've got a few gallons of whatever it inside, and I don't even want to think about how much that tank over there might be holding.� I never even liked getting shots; I'm not sure how I'm going to handle having all this flowing into me.� Then again, this is my only chance if I want to be able to feel good about my body again, and I sure could use that money.

����������� �So, what are all these chemicals?� Petra asked cautiously as she glanced around at the elaborate setup that she had been installed in, �Especially that big one there, what's it for?�

����������� �Ah, I always love a curious patient,� Doctor Bloom said with a smile as she turned away from the a screen filled with rapidly changing numbers, �Basically, the two in your arm there are just hormones and drugs of my own concoction, designed to prime your body for the serious changes it's going to be enduring.� The small ones in your breasts are sort of a catalyst; they're what are going to make sure all the weight you gain goes where we want it to, and that you don't just start fattening up all over.� Finally, the big one there is the serum itself; almost impossibly rich in everything your body uses to gain weight in a hurry.�

����������� �Why does it have to be so much bigger though?� Petra asked, the large needle still feeling cold and foreign in her arm.

����������� �Well, you're going to be gaining an awful lot of weight in a very short time frame,� Doctor Bloom explained, �If we're going to fill your breasts up with as much as you say you want, all that mass has to come from somewhere, and we've got to get it into your bloodstream fast enough to keep up with your body's growing demands.� It's much more cost-effective to store the substance in large quantities though, so the tank is designed to hold a hundred gallons of the serum, not that I expect we'll be using that much on your today, of course.� Was there anything else then, or are you ready to begin the process?�

����������� �Yes,� Petra said softly after a moment's tense hesitation, �I'm ready whenever you are.�

����������� �Marvelous then,� Doctor Bloom said as she turned away to enter a few final variables, �Now, when we begin you may feel a certain tightness in your breasts as the serum begins to work.� You may also feel slightly light-headed or tingly, and I assure you that is all perfectly normal, so whatever happens, please remain calm.� We've got you hooked up to an awful lot of different bags here, and you wouldn't want any of them pulling loose, now would you?� Okay then, three...two...one- and there we are.�

����������� There was a soft whirr as countless small pumps hummed to life, and Petra suddenly felt an odd coldness around all the injection sites in her breasts, goosebumps spreading across her exposed skin.� The feed in her arm felt even stranger; she could positively feel the thrum of the serum flowing into her body, as if the great tank forcing in into her had a pulse all its own.

����������� Okay, this is turning out way weirder than I was planning on when I came in this morning, Petra mused as the doctor continued to type away, glancing back at her patient now and then and making some quick adjustments to the controls, I really hope this isn't one of those things where they outlawed it after some girl died during the trials and now I've just walked in here to let some crazy doctor just fill me up with random chemicals.� Then again, I'm going to be really pissed if after all this trouble something doesn't start to-

����������� And then she felt it- a dozen little pinpricks spread across her chest where the needles were.� It pinched a little, as if her skin was tightening around the injection sites, but it soon passed, fading into a sort of spreading warmth as the thrum, thrum, thrum, of the tube in her arm steadily, almost hypnotically, kept pumping its fluid into her body.� Finally, Petra saw it- the odd sensations in her breasts, the throb of the IV, all of it suggested that something was happening to her body, but now all her suspicions, all her hopes were confirmed by her own eyes.�

����������� Oh my gosh! My boobs are growing! She realized as the two slack udders hanging from her chest began to swell, first slowly, but rapidly picking up speed, this is incredible, my tits are actually filling up again; I can't believe it!� And it feels so good, too; I hope they don't stop tingling like this until I'm at least as big as I was back when I was fat.� I almost wish the doctor wasn't here keeping an eye on me, if this keeps up I could really do with some alone time...

����������� As she relished the sensations expanding through her body, Petra noticed Doctor Bloom shooting her a disapproving gaze and realized that, contra her instructions, she had absentmindedly been kneading at her blossoming endowments and, suddenly worried about dislodging the needles that ensured that only her breasts were going to be gaining weight, let her pleasantly enlarged mammaries fall with a satisfying slap against her belly.� While Doctor Bloom returned to her array of numbers and readouts, Petra was left to watch as her bosom steadily grew to its former glory.�

����������� Already her bust had ripened considerably.� While Petra's breasts remained far from perky, still weighing heavily upon her lap, they were becoming irresistibly full.� Where just a few minutes before they had only met together where they pooled in her lap, Petra felt an electric twinge of excitement as the space between them dwindled until she felt each breast push with gentle heaviness against the other.� Before this her breasts had felt like nothing so much as two balloons that had been overfilled until they were fantastically overstretched, and then deflated, their stretched-out skin vastly in excess for the modest volumes they now needed to contain.� Now, however, with Doctor Bloom's machine filling them up with such efficiency, Petra began to think about just how far she wanted to go with this procedure.

����������� To think purely in terms of what size she wanted to be was pointless already.� Before she had even set foot in the clinic her breasts, unexciting as they were, were still ridiculously out of proportion to her figure.� The moment she had agreed to the procedure she had known that she would be walking out of here with a pair of melons swollen enormously beyond what could pass for normal; the only question now was how far beyond that she was willing to go (assuming Doctor Bloom's treatment lived up to its billing).� Petra savored the growing weight pulling on her chest, the way they became heavier and heavier as they soaked up the rich fluid coursing through her veins.� It was impossible to be sure without laying them on a scale, but each one felt like it surely had to weigh at least twenty pounds by now, double what her boobs had weighed before the procedure had begun.�

����������� Petra's growth was starting to become more visible, as well.� A polished steel mirror on the nearest wall reflected a bosom swollen to dimensions that could make a woman a very popular model in certain circles, and while her breasts still hung from her chest with a heft that left no doubt her body remained solidly in the thrall of gravity, their increasing fullness was well on its way to make Petra's bust into something she could be proud of again.� Before, her boobs had felt like pancakes a foot wide and half an inch thick, but now as she looked down at her gently-billowing cleavage, Petra realized that she had never hated having big boobs, just having such limp, shapeless ones as she had been forced to grow accustomed to.

����������� I'd forgotten how nice it is to look down and see a nice big, soft pair of tits, Petra thought, as Doctor Bloom smiled approvingly at her subject's expanding endowments before returning to her notes and adjustments, It just feels so good to feel them filling up again, getting all fat and juicy like they used to be.� I know I'm going to look like some kind of porn star nympho if I leave here with boobs the size of Pilates balls or whatever, but this is just too incredible to stop now.� With any luck soon I'll be on my way home, my big boobs bouncing and wobbling as I walk, the way they'll feel so sensitive, so stimulating, two swollen mountains of tender flesh just trembling with excess.� I can hardly wait to get home and get naked; pinching, rubbing, squeezing them until I just have to come.� Oh, I think they're growing even faster now, I hope this keeps filling me up until I'm ready to pop!

����������� �Ah, Miss Jennings, your pulse seems to be racing a bit, are you feeling quite alright?� Doctor Bloom asked, arching an eyebrow as she glanced at her expanding patient.

����������� �Oh, um, no, I'm fine,� Petra stammered, hoping that the rosy flush of desire expanding across her more than ample bosom hadn't given her away too obviously, �Is it bad if my heart is beating a little fast?�

����������� �Oh, no, not at all,� the doctor said with a smile, jotting down a few more hasty notes, �It's just that the faster your pulse rate, the more of the solution the machine will have to pump into you to keep up, so your rate of growth may increase substantially.� It should be harmless enough; though you are welcome to tell me if you feel any discomfort connected with such rapid weight gain in your breasts.�

����������� Doctor Bloom clearly wasn't expecting an answer from the delightfully overstimulated Petra, going back to her screens as her burgeoning patient once again fell into the self-indulgent reverie of her own expanding figure.� Another sudden rush through the IV told Petra her dosage was indeed increasing, as her breasts continued to weigh heavier as they grew.� Their shapelessness was all but gone now; her nipples, once buried against her thighs beneath twin masses of quaggy flesh, were now firm and taut, each projecting proudly from the lower hemisphere of the luscious curves of Petra's now watermelonesque breasts.� She had now been filled beyond any hint of sagginess; while her breasts were still exquisitely soft and welcoming, the bulk of their considerable weight no longer rested on Petra's thighs, but tugged seductively at her chest.� Her breasts were swollen to a state of ravishing fertility now, a degree of voluptuousness that only hinted at what delights might be found within her ample embrace.

����������� Yesss, please just keep it coming, Petra thought, hoping desperately that Doctor Bloom couldn't hear her stifled sighs of desire over the whirr of the pumps, I think they've gain another ten pounds each just in the last few minutes; just look at what a canyon I've got between my girls now! Oh, I definitely wouldn't be ashamed to let these babies slip out of my bra in front of some lucky guy after a hot date.� How did I just forget how amazing it felt to have tits like this?� Or is there something in all these drugs that's just making me super-horny?� Even the good doctor over there is starting to look pretty good to me, what with that nice, round ass of hers all jacked up on a pair of fuck-me heels and her lab coat hugging those big, fake, stripper tits of hers so tight.� I mean, they're nowhere near as big as mine, but still, if she peeled out of those clothes and came over to give me a personal examination, I'd just lay back and let those clever hands do anything to me.

����������� As Petra's swiftly-swelling breasts bloated out wider than her shoulders, she began to feel just the faintest hint of tension in her skin.� It wasn't painful; if anything it only served to stir her arousal to greater heights, and as she looked down at the full, heavy torpedoes jutting out invitingly from her chest, Petra licked her lips with anticipation, relishing the feel of her breasts being fattened to the point where they were finally not just getting fuller, but bigger.�

����������� How fast am I growing now? Petra mused incredulously as she realized that her charms now bulged out just shy of her knees, it feels like they're each gaining a gallon a minute here.� Still, they're finally starting to get so nice and round; it's going to be hard to resist going around braless with these big, soft melons stuffed into the tightest tank top I can cram them into without tearing it wide open.� And just look at my nipples; they were never this perky when I was fat, but now they're like a couple of grapes so ripe they look like they're about to split their skins.� I know I never� got off on sucking my own tits before, but now, they're just so big and juicy I think I could spend hours with these things in my mouth, assuming I don't end up so big I can't even reach them anymore.� Is that even possible?� Could my boobs be pumped up with that much fat?� I guess now I'll have to find out for myself; as hot as the idea of sucking my own tits is, how much hotter would it be for my nipples to be so tight and throbbing that I'd give anything to feel my tongue against them but have my boobs be so huge I couldn't reach them?� Oh, I think if that happened I could torture myself for hours at a time before I needed anything else to stir me up.

����������� �Still comfortable, Miss Jennings?� Doctor Bloom asked absently, still focusing on the numbers streaming across her terminal, �My, but you're taking it in at a prodigious rate.� In our earlier trials all the volunteers who went this fast were screaming for relief by now; when we were first trying to find the right dosage rate we had one poor girl take in ten gallons in as many minutes and she ended up with the most spectacular stretch-marks before we could shut the system down.� I never would have thought a woman's breasts could become so fat they might burst, but the sight of her sitting on that table just throbbing with excess, the way she was holding them, afraid to let them hang free but terrified of anything more than the lightest touch- I can still remember the sound of her skin stretching to hold it all, and the way she whimpered when we finally had to shut the experiment down to keep her poor breasts from exploding.� I was so surprised when she decided to keep them rather than try to have the process reversed.� She could hardly walk by the end; it had to be fantastically upsetting, every single nerve in her breasts strained to the very limit, and yet, she seemed oddly content with her new burden.� Not that you need to worry about that, Miss Jennings, I just mean to say that there seems to be something remarkable about your physiology that allows your body handle so much of the serum so very quickly.� I know you're probably not planning on getting too much bigger than this, Miss Jennings, but if you did want to let us see just how far your body would accommodate this procedure, I could certainly make it worth your while.� At the very least, we'll have to recruit more young women like you who have suffered serious weight loss recently to see if any of them react as favorably as you have.�

����������� The doctor's words barely penetrated Petra's thoughts though, so completely lost had she become in the sheer, overwhelming sea of bliss lapping teasingly against the walls of her body.� The strips of tape holding the control needles in place were beginning to pull tight as the skin beneath them stretched to accommodate their growing volume.� As they expanded, Petra's breasts began to weigh more heavily on her thighs, looking for all the world as if they might at any moment overwhelm her shapely legs completely, and enveloping them in the embrace of her expansive cleavage.� Their upper curves were growing more and more impressive as well; the gentle arc from nipple to collarbone was becoming more convex by the second, her breasts bulging towards ever more improbable voluptuousness.

����������� Okay, I just can't contain myself any longer, Petra realized, biting her lip as she worked a hand underneath the bulk of her wobbling bust, She's so into that computer over there she probably won't even notice if I slip a finger or two down into my undies; my tits are so huge by now it's not like she could see what I was doing down there anyway.� Damn, this is just making me so horny I can hardly stand it, besides, I'm sure even if she catches on, this can't be the first time one of her patients had a little fun on the table here, and if I don't get myself off soon here, I'm really going to lose control before long.

����������� Her breasts now each fattened until her breasts stuck out nearly a foot to either side of her sleek body, and her slightly parted knees hidden in their shadow, Petra slipped her hand past the elastic of her panties.� Her arousal had already left her invitingly warm; her hand felt cool, fingers parting the tender flesh of her femininity, already swollen and slick with desire.� She slipped a finger inside herself; her desire blazed within her as the monitor on the other side of the room suddenly emitted several rather serious sounds.� Doctor Bloom half turned around but then, deciding to leave her patient to her own devices, went back to work, leaving Petra to indulge her achingly inflamed appetites.

����������� Oh, this just feels too good to be true, Petra thought, forcing another finger into her swollen depths as another pulse of bliss set her body shuddering, Okay, maybe I'm not going to be able to keep this quiet.� Just look at the way my boobs are jiggling; she has to know what I'm doing.� Oh, I just don't care anymore; if she keeps pretending not to notice me over here giving myself a fat lip I'm just going to lay back, go to town and really get my tits all aquiver.

����������� �Miss Jennings, I'm reading an alarming spike in your pulse rate again; are you quite sure you're feeling alright?� Doctor Bloom asked knowingly as a fresh round of alerts popped up on her screen, �If you're in any kind of distress, I can certainly shut the whole thing down.� The last thing I want is to cause you any discomfort or inconvenience.�

����������� �Ah, no, I'm fine,� Petra panted, trying to look innocent, her breasts now bloated to nearly the size they had been before her diet and heaving like two overfilled water balloons on a trampoline, �I just, um, I'm not used to such, uh, powerful sensations as this.� I'm fine, really. I'm good; you- you just keep on with the experiment.�

����������� �Well, as long as you're fine then, do you mind if we increase the feed rate by a little more?� Doctor Bloom asked innocently, �I never imagined I'd have a patient who could take so much so quickly.� I mean to say, you've probably already taken in a good twenty five gallons of the serum; I'd love to see just how high a dosage you can take before you feel you've reached your limits.�

����������� Petra didn't say a word; in the back of her mind she knew the last thing she needed right now was for her breasts to be growing even faster than they already were, but she was so hot now, so insatiable in her desire for more that she couldn't bring herself to resist.� It was crazy to even keep going at this rate, but stirred to such lustfulness, Petra found she couldn't deny her unquenchable thirst for more, and so with eyes full of doubt she nodded meekly at Doctor Bloom, who smiled broadly in return.

����������� �Ah, wonderful,� the Doctor said, �Let's dial things up by, hmm, fifty percent here then, okay?�

����������� As she tapped at the screen, Petra felt another surge of serum pumping into her body.� Her arm was starting to ache where the cuff wrapped around it, and the wait before her breasts began to expand with renewed vigor was a short one.

����������� Oh, come on! If you're not going to call me out on fooling around here don't just tease me like this, Petra thought, her head swimming with thoughts so shameless and wild that her shock at their erotic excess was only slightly less than her eagerness to indulge them to their fullest possible extent, If you're trying to see how much of this I can take without just having a screamer right here on your operating table, then come over here, tear off my panties and finish the job yourself!� I'm so top heavy I can barely even sit up; just push me back, spread me wide and eat me out, already.� Oh, I can just imagine those big, fake jugs rubbing against my skin; I'd just love to force that pretty head of yours in between my big, fat tits until you were fighting for air, your hair tangled around my fingers as I pushed your face right between my legs and held you there until I decided I'd had enough.� Oh, I see you playing coy, but you've got that look about you, Doctor Bloom; you've made more than one woman delirious with pleasure in your life, and I bet a few of them have been right in this very room.

����������� Petra was inflating at a spectacular rate, the machine forcing countless pounds into her body, every last bit of it going directly into her overfed breasts.� They billowed out over her knees by several inches now, her thighs buried completely by their sumptuous excess.� Only the fact that they were finally nearing their capacity kept them taut enough that they didn't simply spill across the Petra's lap and onto the examination table. Each was bloated to more than a foot and a half wide, her creamy skin at last beginning to show the strain.� Their immense weight tugged at Petra's shoulders unforgivingly, her breasts round and lush and so intoxicatingly full that they didn't so much hang from her chest now as stick out from it, her dimpled nipples protruding just below the equator of each of her swollen spheres.

����������� �Congratulations, Miss Jennings, it appears that you're back to you old size now; well actually a little more than that,� Doctor Bloom informed her, �According to my readings the fat saturation levels in your breasts are at 102 percent, no, wait 103.� Do you want me to go ahead and terminate the procedure?� I would advise against continuing too much longer unless you feel confident about how much you can exceed your limits, but as well as you've handled things so far, I expect we could push you all the way to 120 or 125 before you were in any real danger, provided you're willing to live with the consequences, of course.�

����������� Petra knew the only sane answer was to shut it all down now.� Even when she had been so fat she could hardly squeeze into her car, her breasts had been ridiculously out of proportion to the rest of her, on her much more slender figure they were positively gargantuan.� The doctor had just told her she they were bigger than they'd ever been, and every second Petra delayed they were only growing heavier, the strain of holding so much quivering flesh becoming more and more exquisite.� The readout behind Doctor Bloom was up to 105 now; and Petra wondered just how many pounds each percentage point translated into.� She was sure she'd have to quit her job at the museum; even if spending all day on her feet carrying all this weight around on her chest around didn't leave her incapacitated with back problem, the director would have to let her go; after all, a fat girl with huge tits wasn't so very out of place in the museum world, but a skinny one with even bigger ones would attract all the wrong kinds of attention.� 107, and Doctor Bloom was still watching Petra patiently, waiting for an answer.� She had been doing more and more translating work online lately, maybe she could just work from home, assuming that she could still reach the keyboard without just mashing all the keys beneath an uncontainable tide of self-indulgent flesh.� 108, Damn, but the tape holding those needles was starting to pinch. 109, Maybe she could put her new assets to use?� She knew a few girls deep into the local burlesque scene; she'd turned down more than a few invitations over the last year, and there had to be a place in the show for a girl with tits so big she could hardly walk.�

����������� Well, I'm already so huge I'm probably just going to end up spending all my time at home fooling around with these anyway, Petra decided as the readout reached 110, They probably don't even make bras big enough to fit me anymore; holding up that much weight would make the strap cut right through my shoulders.� Besides, since from here on out I'm going to be �That Girl With Gigantic Boobs� to everyone in the world anyway I may as well embrace my fate and take every drop I can get while I'm here.

����������� �Miss Jennings, I'm still waiting,� Doctor Bloom reminded her.

����������� �Right, sorry, I needed a second to think it over,� Petra told her, �Keep it flowing; fill me up with every last ounce you think I can hold.� Take me right to the limit; even if I'm begging you for relief and my boobs look like that girl you blew up until her tits were ready to explode, just keep it coming until you don't think I can take another drop.�

����������� �Certainly, Miss Jennings,� Doctor Bloom said with a smile, �I hope you realize how enormously helpful all this data is going to be for my research.� I mean, of course you have your own reasons for prolonging the procedure but still, I'm not quite sure how to show my gratitude for your generous contributions to science here today.�

����������� As Petra thought about asking for one or two ways that the researcher could repay her, the sensations coursing through her titanically enlarged breasts were overwhelming.� The paper on the examination table crinkled faintly as the underside of her vast bosom finally made contact with it, and Petra could feel the faint but insistent tug of the needles in her flesh trying to pull free, her breasts now expanded to the point where the IV lines had run out of slack.� Her excitement had long since reached critical mass without any manual encouragement, and Petra pulled her hand free from her sodden panties.� Her entire body was awash with bliss, and she knew if she so much as touched herself now she'd surely lose any semblance of control over her barely-contained desire.� The machine read 115 now; her breasts were feeling awfully full, and Petra began to wonder if she could really make it to 125 before the strain grew to be too much for her.�

����������� Her reflection showed her nipples engorged to the size of overripe strawberries, and so excruciatingly turgid that Petra was sure that if someone pinched one of them even lightly she would come as she had never dreamed she could.� Her areolae were drawn out as wide as saucers, their tender, stretched-out skin now a bright rosy hue that stood out against the paleness of her breasts, their few bumps now spread out across their greatly expanded area.� The tape holding the needles in place was beginning to tear; the skin it was stuck to was stretching too far for it to hang on as Petra's breasts were forced to grow fatter and fatter.

����������� �You're at 120 percent, Miss Jennings,� Doctor Bloom noted approvingly as she glanced back at Petra's breasts, each swollen to two feet across and visibly straining with indecent lusciousness, �Shall I stop now, or do you think you can handle just a little bit more?�

����������� Oh, my boobs feel like they're about to pop, Petra thought, a couple of needles tickling her overstimulated skin as they pulled free, But this is just too good to quit; I don't think I could force myself to tell her �stop� even if I knew I was about to burst.

����������� �No, please,� Petra insisted, her massive mammaries heaving with obscene excess as she struggled to catch her breath, �Give me as much as you can.�

����������� �But of course,� Doctor Bloom said with a smile, �I think you can hold another point or two before your breasts pass their saturation point and start to-�

����������� Interrupted by the sound of several alarms going off on the control console in front of her, Doctor Bloom turned her full attention to her machine.

����������� �Wait, what's going on?� Petra asked, suddenly worried, �Am I going to-�

����������� Her question was cut off as she gasped for air.� The flow of serum into her body felt like it had increased tenfold.� She could hear the fluid gushing through the tube in her arm; her hand was already starting to feel cold from the sheer volume flooding into her body.� And then it happened.

����������� Petra's breasts were already enlarged to the utter limits of safety, but now with all the swiftness and force of a pent-up river topping over a dam, they began to billow to more spectacular dimensions as gallons flowed into them in just a few brief seconds.� Already they were almost painfully full, and as they ballooned farther and farther beyond her knees Petra found she had to lean back if she didn't want their accumulating weight to pull her right off the table.� Leaning back, Petra could feel their bulk weighing against her chest, against her belly, which was starting to push her vast bosom even further forward.

����������� �Doctor, something's happening! It's not just my boobs; I'm getting fatter!� Petra cried, alarmed as her trim figure began to grow softer and fuller before her eyes.

����������� �I know,� Doctor Bloom said, her hands a blur of motion as she frantically tried to regain control of the system, �I failed to account for how such extreme breast growth would inevitably lead to the moderator needles pulling free from the subject's body, and without them to draw the rest of the serum into your bust, the computer is now trying to saturate every fat cell in your body with just as much as we've managed to pump into your breasts.�

����������� �What? But they're already so huge I'll barely be able to walk; how much more does this thing think I can take?� Petra said as she reached a hand underneath her mammoth bust and found that her belly was already pinchably chubby, while the sound of crinkling paper around and behind her attested to the fact that her hips and rump were plumping up to similar proportions.

����������� �I'm sorry; I'm doing everything I can to shut the system down,� Doctor Bloom tried to reassure her, �But your entire body is filled with fat cells shrunk by your diet down to a fraction of their natural volume; it's like throwing a dry sponge into a swimming pool, nothing can stop your body from absorbing as much as it possibly can.�

����������� �But what happens if you can't shut it down before then?� Petra moaned, �Please work faster, I feel like I've put on another twenty pounds in the last few seconds!�

����������� �If I can't shut it down then it's going to keep on pumping more into you, just like we were doing with your breasts,� Doctor Bloom explained, �Oh, I am so sorry about all this, but at a high enough dosage it could certainly take you far beyond your previous maximum weight.�

����������� Petra could feel herself gaining more.� Hidden beneath her swollen breasts, she felt her slender thighs growing softer and more squeezable by the second; her swiftly expanding belly inching out further and further along them.� Her seat on the hard table rapidly became more comfortable as her own degree of padding increased at an alarming rate, the waistband of her red panties growing snug around her billowing waist.� Though most of her body was blocked from her view by her massive melons, Petra watched the leanness of her shoulders melting away as their contours grew softer; she felt the cuff just above her elbow growing tighter as her arms fattened steadily, as if they could hardly wait to once again be so big around that even the largest sweaters fit her like a second skin.� As if in response to this constriction, the machine upped her dosage again; the serum surged into her body with an almost orgasmic intensity.� Aside from the throbbing pulse of the IV pouring its contents into her, Petra's arm was numb almost to her shoulder now.

����������� This can't be happening, Petra thought to herself, fighting against the terror that threatened to overwhelm her senses completely, I can't just sit here while this machine forces who knows how much of this stuff into me.� I'll weigh a ton by the time this is all over, assuming I even last that long.� How will I even move?� Why did I ever agree to this stupid experiment?� I just keep getting bigger!� They'll have to roll me out of here if this keeps up.� Maybe I really will have to spend the rest of my life stuck at home, too big to work, too big to walk, too big to do anything but try not to jiggle so hard that it makes me come.� How would I even pay the rent?� I guess I could do a bit of web modeling; there have to be some guys out on the internet who'd pay money to see a girl so huge she can hardly get out of bed.� Maybe I could start a podcast or something; I guess I could get used to that, having fans ask me stuff about being so big, knowing there were people out there who thought I was the hottest fucking thing ever.� Oh, why is this taking her so long to fix?

����������� As Petra's body blossomed from beyond mere curvaceousness to entire new vistas of voluptuousness, a new sensation began to penetrate her mind.� Beneath the fear of what was happening to her and how utterly helpless she was to control it, beyond how absolutely vulnerable she was as this machine loaded her body with more and more fat, and the fact that gaining several dozen pounds in the space of a couple minutes was more than a little uncomfortable, Petra realized just how much this was turning her on.� The same tantalizing desire that had flowed into her body when it was just her breasts blowing up was starting to seep in from the rest of her more than ample figure, and for all the chaos and danger swirling around and inside of her, Petra felt her lust rekindled by the sensation of her thighs filling to the point where she had to spread them apart just to keep them from squeezing together too distractingly, the way her hips now spread several tantalizing inches wider than her far from narrow waist, and the way that her ass now jiggled and wobbled excitingly every time she shifted her weight even in the slightest.� Her panties now hugged her most feminine of curves with wonderful, maddening tightness, and despite her dire situation and the doctor on the other side of the room desperately trying to shut down the machine that seemed intent of filling Petra to immobility, she found herself growing more and more aroused by each ounce the machine pumped into her unresisting body.

����������� I must be losing my mind, Petra thought with dread, My tits alone are so full I'll hardly be able to stand after this and my belly is already so huge I can't even keep my legs together.� Why is this getting me so fucking turned on?� I'm stuck here, pinned to this table by my own boobs while I just get fatter and fatter; what's wrong with me?� Do I have some kind of weird fetish that just sprang to life; have all these drugs just melted my brain and turned me into some horny bimbo?� Oh, if only I could stop thinking about how incredible touching myself all over would feel right now.

����������� �Oh no,� Doctor Bloom said, pausing for a moment from her frantic efforts, �This is even more serious than I feared.� Miss Jennings, I'm afraid the system isn't just fattening up your figure to match your breasts.�

����������� �What do you mean?� Petra asked, still in a haze of desire, confusion, and dismay at having her figure more than double in size, �This machine of yours is already turning me into a fucking hippo!� What else is there to go wrong?�

����������� �This,� Doctor Bloom said, pointing soberly at a big 138 on her screen, �Miss Jennings, it seems I was mistaken; the serum is still forcing your breasts to become larger.�

����������� �How?� I thought you said this thing was just trying to fatten the rest of me up to match my boobs,� Petra demanded, suddenly aware of how much fuller her already overfilled breasts had become while she was distracted by the rest of her expanding figure, �Didn't you tell me that anything above 125 would make my boobs explode or something?�

����������� �I wish I could explain it, I really do,� Doctor Bloom admitted, �But we've never taken a patient as far as this and clearly my calculations missed something critical.� Still, please don't panic.� I merely said that 125 was the most I could recommend you handling safely under normal conditions.� As long as you remain calm your breasts should be to withstand considerably higher saturation levels, at least until we can shut the system down and work on reversing what's happened to you.�

����������� �I should be able to handle more?� Petra shot back, inching back further onto the table, the motion setting her immense breasts jiggling with uncontrollably, �According to your numbers this shouldn't be happening in the first place!� To hell with that, I'm pulling this damn thing out of my arm before anything else happens!�

����������� �No- you can't!� Doctor Bloom shouted, grabbing Petra's free hand with a strength that she hadn't known the buxom surgeon possessed and fixing an icy stare at Petra, �Please, Miss Jennings, the hormone levels in your body are already dangerously unbalanced.� Your entire body is brimming with synthetic bioactive compounds.� Things have already happened that my theories can't explain; if you just pull the IV out right now it would almost certain send you into shock; for all we know the consequences could be catastrophic!�

����������� �So I'm just supposed to sit here and wait while this stuff just keeps pumping into my body?� Petra pleaded.� Her panties were digging deeper and deeper into the billowy softness of her waist by now, and their tightening embrace only reminded her how uncontrollably hot this was all making her, �I'm already fucking huge!� What kind of plan is that?�

����������� �I'm sorry, Miss Jennings, but I'm afraid it�s the only one we have,� Doctor Bloom explained, eyeing her patient carefully as Petra's breasts ballooned to the point where their unbridled expansion had brought them level with Petra's now-plump shoulders, �The system has locked down primary control completely; any attempt by me to gain access at this point could cause it to increase or decrease dosages in a completely unpredictable way.� Believe it or not, even now the system is carefully monitoring and balancing the ratios being fed into your body; I hate to even imagine what might happen if one chemical or another were to suddenly spike.� However, there is another option; I designed a failsafe to activate when the main tank becomes empty.� Regardless of what the system's sensors are telling it at that point, it will power itself down in a controlled manner and then we can work on treating you further.�

����������� �So that's the plan then?� Petra asked in disbelief, �Just sit here and hope that I can take a hundred gallons of this stuff and see if you can't do your best afterwards?�

����������� �I know it isn't easy to accept, but I believe that is by far the safest course of action,� Doctor Bloom said somberly, �I'll continue to monitor the system and make any minor adjustments I can to increase your comfort.� And of course, this circumstance takes us far beyond the normal rules of etiquette for a doctor's office, so please don't be afraid to do whatever you decide you need to get through this.�

����������� �I guess I don't have much of a choice when you put it that way,� Petra allowed as the big number reached 146, her breasts now swollen to the point where she could no longer reach her arms around them, �If you need me I'll just be over here with my weather balloons.�

����������� As Doctor Bloom returned to her numbers once again, Petra was left to herself, the machine still relentlessly pumping more and more fat into her already overfilled body.� Her once-narrow hips now swelled out six inches wider than her shoulders, her thighs barely less engorged in comparison.� Just below her waist Petra's massive ass bulged out nearly a foot behind her, its vast expanse of pale flesh quivering submissively as it was laden with more and more and more.� Petra gasped in discomfort as the waistband of her panties dug in deeper around the circumference of her sumptuous form.� As the machine stuffed her far beyond what her body had ever held before, her waistband, stretched more than four times its proper dimensions, finally surrendered with a snap that set Petra's quivering figure rippling.

����������� Finding herself sitting there naked, torn between abject terror as the readout climbed to 157, and how undeniably arousing her hopeless situation had left her, Petra decided to give in to the latter.� Her right arm still all but paralyzed by the torrent of serum gushing into her, she carefully worked her left towards her goal.� Around the two huge, quaking melons which now overhung her thighs completely she reached, working her fingers under the yielding curves of a belly fattened to scandalous lusciousness.� Petra found that no matter how far she spread her lush thighs they still pressed against each other fulsomely, rubbing together in ways that only served to inflame her passions.� Undeterred she probed her way between them and finally reached the object of her efforts.� The tender flesh she felt yielding to her touch had not been spared the effects of the procedure; her lips had been plumped up with fatness until they felt ready to burst with ill-contained pleasure, so tight that no matter how hot, how soaked with desire Petra was it was a struggle to gain entry.� Still, she was desperate; she could hear her breasts stretching to accommodate their overwhelming burden, every fraction of an inch that they surrendered sending tantalizing vibrations of frustrated desire surging through her body, and as the machine reached 161, Petra slipped inside herself.

����������� She came.� Her depths swelled inward from the indescribable fullness of her body and Petra screamed as if a thousand volts of pure, distilled bliss was being siphoned into her pleasure-drenched form.� She arched her back, muscles sore from supporting her growing weight tightening reflexively in uncontrollable spasms, bouncing and rocking so hard that she came close to slipping right off the table.� Her rough treatment set her breasts bouncing wildly; their skin protesting audibly as they strained to hold a barely-contained flood of quiversome flesh.� As soft and rounded as Petra's knees now were, her breasts hurt where her silk-smooth thighs pushed up against the tender underside of her bosom; even the slightest pressure felt like it might well be too much for her overfilled breasts to bear.� Even so, the aching sensation of excess, the slap of her overfattened bosom smacking against her huge belly, the awkwardness of her plumped up arm trying to push so much ponderous but pleasing flesh out of the way, only served to amplify her ecstasy even more.� Petra struggled for air, each breath made labored by the heaving bulk of her titanic bosom.� She no longer cared that she was so close to Doctor Bloom, who still kept a watchful eye on a screen wholly covered with blaring red warnings about maximum flow rates and� dangerous supersaturation.� Now gasping for breath, Petra knew she needed to slow down.� The tube in her arm jumped visibly as it delivered each pulsating burst of fluid into her now, her heart hammering away with abandon.

����������� Trying desperately to calm herself, Petra tried to be content with simply petting herself, keeping her lust at a rolling boil but no longer so carelessly abusing her spectacularly overladen body.� She blinked in amazement as she saw the monitor now bore, in addition to reports of any number of system-breaking faults, the number 203.

����������� Is that even possible? Petra wondered, staring for a moment at her obscenely distended breasts in shock, Are my tits really twice as heavy as they were back when I was fat?� There were times then when I thought if I gained another ten pounds my boobs would explode, but this- just how gigantic can I get?� I can feel them stretching to hold it all; I can't imagine how I'll be able to stand with so much weight hanging from my chest.� They're just getting so tight; like a couple of water balloons that someone forgot to stop filling up.� And what about the rest of me?� If my ass gets any bigger I'll hang over the sides of my bed at home, and my belly's getting so huge that spreading my legs to give it growing room is actually starting to hurt!� I need to keep myself under control here; Doctor Bloom said my chemistry is all sort of unbalanced right now; now that I've given myself a bit of fun I really need to calm down a bit.� Shouldn't that machine be empty by now?� Maybe there's still some more left in there... No, dammit, what am I thinking?� Do I actually want to get bigger?� I've been violated, turned into some kind of human blowup doll, my life put in danger, how can I even think about wanting more of this?� All these hormones must be making me crazy; if I don't stop thinking like this now I'll be begging the doctor thee to hook me up to another tank before long.

����������� Trying to keep calm, Petra stared on as her breasts continued to fatten.� Inch by rapturous inch they expanded, and each one of those ravishing inches increased their weight by more than the one before.� With most of their weight resting on her lap and the exam table, they spread out slightly under their own weight, each one swollen to nearly three feet across, her once rosy areolae stretched into faded pinkness as their tender skin was drawn tighter and tighter by the indescribable overfullness of her fat-glutted breasts.� When Petra tried to look down, she felt the caress of warm, taut skin against her chin, and saw spread before her the trembling vista of what seemed like an endless expanse of pale flesh, faint blue veins now clearly visible tracing paths gently across her tremulous bosom.� Though harder to see, even a casual feel told Petra that her lower half was less extravagant only in comparison.� Not considering her bust, Petra had always thought of herself as rather dramatically pear-shaped, and now that this procedure had filled every last inch of her with as much fat as she could hold, Petra found herself perched unsteadily atop a behind of breathtaking dimensions, sitting more than six inches higher than when she had first sat down, so many countless gallons had been poured unasked into her boundlessly compliant body.�

����������� The monitor read 217 now, and Petra felt the fullness becoming unbearable.� Her breasts groaned as the machine pumped fat into them by the gallon, their weight increasing to the point where Petra realized that only the counterweight of her massive rear was keeping her from toppling right off the table and onto her tantalizingly overripe melons.� Her legs were so fat now that they jiggled from hip to ankle, her arms so utterly plump that they wobbled almost down her wrists, save for where the cuff constricted around her right one with painful severity.� As Petra watched the numbers climb inexorably higher, wondering just how much more of this she could take, she felt her belly swell out until it overtook her knees, spreading like jello across her thighs, the sheer size of it and her wobbling bosom forcing her to contort her back to give everything enough room for her to remain sitting.� At 225, she gave a start as the main tank suddenly issued a loud popping sound, a moment later a fresh cluster or warnings flashed across the screen as Doctor Bloom cried out in dismay.

����������� �No, dammit, just shut down, you stupid machine!� She shouted, pounding the keyboard with both fists, �You're supposed to shut down when you get critically low!�

����������� �What is it now?� Petra asked, knowing she wouldn't like the answer.

����������� �The main tank; it's almost empty,� Doctor Bloom despaired, �But instead of just powering down it's trying to compensate by raising the pressure.� There's nothing I can do to stop it!�

����������� Before she had a chance to respond Petra heard the pumps roaring to life, the sheer volume of fluid flooding into her made even her benumbed arm ache up to her shoulder, and she felt herself expanding faster than she ever would have dreamed possible.� Untold gallons surged into her helpless body, meekly receiving immensely more than her distended breasts should have been forced to take in.� In the space of a few seconds they surpassed three feet and swelled as if determined to make even those dimensions seem trivial in comparison.� Petra moaned as they grew heavier and heavier; the fact that they were filled far beyond any decent limits seemed to only make it easier for the machine to fatten her with more.� Her skin strained at the obscene volume of fat her breasts now contained, excruciatingly tight yet still enticingly supple.� Petra's nipples felt ready to pop; until now her breasts had expanded smoothly and evenly, they now ballooned in unpredictable bursts, as if being stretched so tremendously beyond their limits had left them unable to do anything but surrender a few inches at a time.� Each spurt of growth left her desperately overfilled bosom throbbing and sore; her breasts now rising to the point where they brushed with teasing insistence against Petra's cheeks, and looking down she noticed faint striations spreading across her areolae, each one now drawn out to nearly a foot across.� She realized now that not an ounce was going to the rest of her impossibly fertile figure, as if either she had simply gained too much weight everywhere else to take in another drop, or the prolonged treatment for her breasts had somehow left them uniquely vulnerable to this final fattening.�

����������� They just keep getting bigger; how can my boobs even hold so much? Petra despaired, her cleavage pressing warmly against her neck, they�re just so damn jiggly; I feel like I've had a tanker full of jello pumped into me, and all I can think about is how I don't want it to stop.� What am I even going to do with boobs this big; just lie around horny and frustrated until I can convince someone to come suck on them to get me off?� Okay, I guess I could actually get into that.� Still, this is insane; no matter how I'm dressed after this I'm liable to get arrested for public indecency, waddling along with my tits bouncing against my knees, assuming I can even walk once this is all over with.� I really am going to have to get a webcam and spend my days jiggling around my apartment for money if I don't end up in some kind of secret government research hospital or something.

����������� Petra held her breath.� She longed for this to end, to hear the pumps fall silent before they filled her with more than her helplessly over-enlarged breasts could endure.� And yet, something about all this, the way they grew heavier and heavier on top of her overstuffed belly, the way they throbbed with such boundless excess, even the unbearable tightness as they stretched and stretched from this punishment; Petra couldn't deny that every second it lasted only left her more aroused, a sensation that both terrified and excited her in ways she fought to understand.� As the tank ran dry, the machine managed to push one last surge through the tubes.� Petra felt her breasts balloon outward by another three inches in the blink of an eye.� She screamed, the exquisite sensation of instantly gaining so much sensual and tender flesh bringing her to a climax that set her entire body quaking and trembling.� As the waves of pleasure beat savagely against the inmost walls of her womanhood, Petra was dimly aware of the dying hum of the machinery.� As the table beneath her protested faintly at having to support a woman several times heavier than the one who had sat down on it half an hour before, Petra heard the sharp clack of high heels on the hard floor.� The room spun lazily as she opened her eyes, thirstily sucking in great chestfuls of air, she saw Doctor Bloom standing enquiringly before her.� The monitor over her shoulder now contained only two things, a cheery message reading �Augmentation Cycle Completed: All Systems Nominal� and the number 242.

����������� �Well, Miss Jennings, how do you feel?� Doctor Bloom asked solicitously as she gingerly freed Petra's arm from the confinement of the injection cuff, expertly bandaging the injection site, which seemed several times too small to have funneled such a massive quantity of liquid into her body in so short a time, �Can you breathe?� Does anything hurt?�

����������� �I feel- I feel huge,� Petra managed, trying to take inventory of just how enormous she had become, �Just- just give me a second to catch my breath here.� No, I mean, my boobs ache like they're about to split their seams, and my back hurts some from trying not to fall off this table for the last half hour, and my butt's kind of falling asleep from holding the rest of me up through all this, but no, actually I feel kinda good.�

����������� �Here then, Miss Jennings, let me help you down if it will make you more comfortable,� Doctor Bloom said, offering Petra her slender arm, �Be careful now, your legs are going to be supporting much more weight than they're accustomed to.�

����������� Awkwardly, Petra slid off the table and planted her feet on the floor, the doctor politely ignoring the noticeable damp spot where she had been sitting, as well as the pair of red panties, stretched and shredded beyond recognition.� Now that she was standing, the lower curves of her breasts stretched to just below her knees, though with a gap of more than a foot in front of them owing to the immense size of her lush and self-indulgent belly.� They were not quite so wide as they had been while stacked up in Petra's lap, but still more than round enough that she could easily read a book opened across their upper regions.� With nothing else to support them, Petra felt pound they had gained straining their tender undersides as they swayed while she struggled to gain her balance.� Up top too, the tug of such sensual ponderousness suspended from her chest was more than enough to make her wonder where she was going to find a bra to help her lug these monsters around or if she was going to have to just pad up a wheelbarrow and push them around in front of her.� Still entirely too wobbly for comfort, Petra turned before the mirror, her sharp intake of breath the only sound in the room as she saw a set of curves reflected that would make a fertility goddess wince at their shameless opulence, her body filled to such delicate excess that she fancied she could almost hear herself jiggling.� Petra had been fattened to a size that should have been impossible due to anything short of a lifetime of the most prodigious gluttony imaginable, or perhaps a couple years as the willing guest of someone dedicated to stuffing her to the gills every waking moment of her life.� Her thighs were so overfilled with fat that Petra had to spread her legs embarrassingly far apart just to stand, though they still looked shapely and modest compared to hips that spanned more than four feet across, so broad that even with her temptingly overstuffed belly and the rolls of fat that had billowed into existence along her sides, she still boasted an impressive hourglass figure.� Petra's ass, so overladen with fat that it bulged out all of two feet beyond the small of her back, was absolutely gigantic, seductively smooth and round despite now being fattened to who could say how many times the size her pert little bottom had been when she came in, quaking enticingly whenever she so much as moved.

����������� �Oh my- I'm fucking huge!� Petra breathed, fighting to wrap her mind around her spectacularly voluptuous figure, �I look like I'm one slice of cake away from exploding!�

����������� �Now, Miss Jennings, please let me reassure you,� Doctor Bloom said with practiced calmness, �Our foundation takes very good care of its experimental patients, especially in cases with unforeseen outcomes.� I know it may seem callous to mention right now, but this procedure has yielded data that our researchers will be able to use to help thousands of people, and as such please be assured that your financial compensation will permit you to enjoy a very satisfactory standard of living, even if you decide that your present condition makes traditional employment undesirable.� Furthermore, any and all of your future medical needs will be paid without question by the foundation.

����������� �Well, I guess I can live with that,� Petra said, surprised at how appealing being this size suddenly seemed, now that her money worries had been so easily waved away, �Is there a catch?�

����������� �No, Miss Jennings, certainly not,� Doctor Bloom assured her, �Though again, I admit that any information gleaned from monitoring your present condition will be of great use to us, your comfort and well-being are our foremost goal, so far as you are concerned.� Also, I know you are likely mortified by your present state, and I promise you that we already have therapies in development which should allow us to reduce you to a less, shall we say, conspicuous size.� If you consent to stay here for the next few days under observation, we may be able to attempt- under the strictest of safety protocols, I promise you- to reverse the effects of your procedure, at least in part.�

����������� �So, as long as I stay here where you can keep an eye on me, you'll do what you can to slim me back down again?� Petra asked, trying to follow everything that the doctor was throwing at her, even while absent-mindedly fondling one of her immense breasts and savoring the provocative ripples of excitement it sent arcing through a body now shaped only for pleasure.

����������� �Please, let me be realistic, there may be no way to undo such, catastrophic changes to your body completely,� Doctor Bloom allowed, �but we will do everything in our power to help you.� And strictly speaking, I cannot compel you to stay here for observation; you are free to go whenever you wish.�

����������� �What if, um, I'm not quite sure how to say this,� Petra began, �but what if I actually like being this big?� I mean, this is way more than I wanted when I signed up for this, but I realize now I kind of missed being fat and well, if I don't have to spend eight hours a day in the museum gift shop getting stared at by weirdoes, I think I could get to like having boobs so huge I can sleep on top of them.� And honestly, this place is kind of freaking me out a bit after everything I've been through; if I want to go home, are you still going to pay me and cover my medical expenses and all that stuff?�

����������� �The short answer to your question is yes,� Doctor Bloom answered, apparently unfazed by the fact that the young woman in front of her seemed so eager to remain like this, �However, I would strongly recommend, for your own good, that you stay here where we can monitor your condition.�

����������� �But why?� Petra asked with a shrug that sent tremors through her bewitchingly swollen figure, �Why does it matter so much if I'm enormous here or enormous at home?� If you want to check me over you can just come pick me up, can't you?� It isn't like I'm going to run away and just vanish in with all the other people who aren't so fat they can get stuck in an elevator by themselves.�

����������� �Miss Jennings, I had not wanted to broach this subject directly if it could be helped, but despite the procedure having been concluded, your condition remains a serious one,� Doctor Bloom admitted, �Your body has been pumped full of more than one hundred gallons of a highly experimental compound, as well as several other powerful hormonal activators.� Your breasts have, in less than an hour, been enlarged to two and a half times the size they were before you lost weight in the first place, to say nothing of how much larger they are now than when you first walked through our clinic's door.� When you came in today, you weighed, according to your initial exam, one hundred and twenty eight pounds; according to my calculations, your current weight is now most likely close to eight hundred and ninety.� Look at you, you can barely move right now.� The most serious reason however, Miss Jennings, is that I have reason to believe that your growth may not be over.�

����������� �How can I get any bigger than this?� Petra asked, at once terrified and fascinated by the thought of her sumptuously overfilled assets being filled beyond their already titanic proportions, �I'm not even connected to your damn machine anymore; where would the weight even come from?�

����������� �Well, strictly speaking, Miss Jennings, it isn't the weight,� Doctor Bloom explained, �Do your breasts feel unnaturally heavy to you?� I ask because it appears that the extreme dosage levels you've experienced have left your breasts in a state of hyper-saturation; the fat cells in your bust are literally filled with more than should even be possible.� We've never seen this before, but if our theories are sound, it is entirely likely that any number of things, physical activity, elevated heart rate, or simply natural hormonal shifts in your body could cause your breasts to expand considerably as your body tries to return to a more stable state.�

����������� �So, how much is considerably?� Petra asked, somewhat distressed that this ordeal was not yet over, �I feel like I've already pushed my luck too far by being filled up this much, how much bigger are my tits going to get?�

����������� �I'm sorry, Miss Jennings, this is new territory for us as well,� Doctor Bloom confessed, �I'm afraid I simply don't know.� It could be as modest adding another inch or two to your bustline, though even that might be more than you ought to risk in your present state, or it could be much more substantial, which is why we would prefer to keep you here for observation.�

����������� �Look, I'm sorry, I get what you're trying to do for me,� Petra said, trying to think clearly, �But I just can't stay here right now.� This whole thing, all of this happening to me- I just need some time back at my place, where I can be comfortable while I figure out whether I want to live my life like this or come back and see if you can slim me down by a few hundred pounds.�

����������� �While I can't say I agree with your decision, Miss Jennings,� Doctor Bloom said, �I certainly understand it.� Very well; if you go out this door and back into the examination room, I'll have some new clothes dropped off for you that should fit you well enough until we can put you in touch with a tailor experienced at clothing women with your somewhat rare requirements; we do keep one or two of them on retainer for cases such as this.� Someone will also give you a cell phone you can use to call us directly; please use it immediately if you experience any unusual after-effects, particularly any further increase in breast size.� When you're ready, I'll have a van waiting to take you back to your apartment; I expect whatever car you drove here in isn't exactly spacious enough for you to drive yourself.� Should you need transportation around town meanwhile, I'll make sure we have drivers on call to take you wherever you need to go, though you may expect to receive more attention than you are accustomed to, should you choose to go out in public in your current condition.� Is there anything else we can do to make your adjustment to this new situation a comfortable one?�

����������� �Thanks, Doctor, but I think once I'm get home and get used to having to take baths with just one boob at a time in the tub with me that this could turn out to be the best thing that ever happened to me,� Petra said, leaning forward to enfold the much slimmer woman in an enveloping embrace that clearly caught her unawares, �Don't worry; I appreciate everything you've done for me, but I'll be fine.� You know, even if I don't need the money, I might give that whole burlesque thing a shot.� Just call me if you need to run some more tests of anything.�

����������� �Thank you, Miss Jennings, I, and my organization truly appreciate your understanding,� Doctor Bloom said as she awkwardly extricated herself from the soft depths of Petra's cleavage, �Again, should you require anything, I am at your beck and call.�

����������� �Oh, and um, if it isn't too much trouble,� Petra added as almost an afterthought, �Could you get one of your minions to send a webcam by my place when you get the chance?� Since I'm not going to be going out much for a while I'd kind of like to be able to, um, you know, get on Skype and stuff.�

����������� �Of course, Ms. Jennings,� Dr. Bloom agreed, with the look of a woman who had just discovered keeping an eye on her patient was about to get much easier, �It should be waiting for you when you get there.�

����������� Without another word, Petra smiled and turned for the door.� Doctor Bloom watched her spreading hips sway back and forth with every ungainly step Petra took, her massive breasts bouncing heavily against each other and her body as she moved, looking every inch as curvaceous from behind as from in front.� From her shoulders to her ankles, her entire body trembled with lusciousness, her smooth, pale skin fairly begging for a lover's touch.� Doctor Bloom smiled knowingly to herself, wondering just how many hours it would be before she got the phone call.
