Attention! This story contains BE, WG, and sexy stuff (well, at least I tried to make it come off that way).  If any of that bothers you, that�s cool; I know this kind of thing isn�t everybody�s cup of tea; maybe you should go learn crochet, or find a crotchety old monk on a mountain to teach you kung-fu.  Those are both good things to work on, and you can be pretty sure that they won't lead to you accidentally seeing a boob.  For everyone else out there, do read on, and please know that I am always delighted to read comments, criticism and suggestions.

Bounce

by: Kodos

�Hi, Hon; long day of work?� I asked as I walked through the door, greeted by the sight of Jenna bent over her sewing machine, a tangle of blue and yellow fabric piled in front of her.

�Oh, hey- is it that late already?� she chirped, looking up from her work, �My gosh, you have no idea.� I never thought that when I started selling cosplay stuff online that I'd ever be this popular.�

�Jeez, is that another vault suit?� I asked, as Jenna finished a seam and lifted her foot off the pedal, �How many is that now?�

�I don't even know; I lost count after the first twenty, and way too many of them requested Vault 69 for it to be anything decent; I don�t think that one�s even cannon, but that�s none of my business,� she admitted as she turned off the light on her sewing table and pushed back her chair, �All I know is that lately I�m getting orders as fast as I can fill them, not that I'm complaining, the money's awfully good for a few hours of work and a bit of denim and trim, but I'd like something that got me up out of my chair for a few hours; my back is killing me.� I wouldn't mind a bit of variety here and there; I feel like it's been ages since I got a commission that really forced me to stretch myself a little.� There aren't any new movies coming out with chainmail bikinis, are there?� I was getting really good at making those. But then again, I'm my own boss, so I suppose I can't fuss too much.� So, what's that you've got there?�

�I was hoping you'd know,� I said, holding the brown box toward my girlfriend, �It was waiting on the front steps and it's got your name on it.�

�Oh- Oh, I've been waiting for this!� Jenna exclaimed, jumping up from her seat, her sewing forgotten as she rushed over and plucked the parcel from my hands, �I ordered it two weeks ago; I was starting to think it was never going to get here!�

�What is it?� I asked, curious as to what had her so excited, admittedly hoping it might be something rather on the naughty side of things; a hope which was not entirely baseless, if past our experience had any bearing on the matter.

�What's- oh, no, nothing like that,� Jenna blushed, as soon as she caught the glint in my eye, �It's just, well, I've been spending so much time sewing and making things lately and not getting nearly enough exercise that, well, I feel like if I don't change something soon; before long I'll be the one I'm sewing double extra-large outfits for, and not just basement-dwelling nerds who really don't have the figure to go to Comic Con dressed as the Doof Warrior.�

�So what is it then?� I asked as Jenna eyed the package intently.� She had a point; after more than a year of trying to get herself established online the orders started pouring in a few months ago, and in order to meet demand she had let her daily trip to the gym fall by the wayside.� I hadn't said a word, not just because the extra money she was bringing in certainly made it easier to keep the lights on, but because, well, I kind of liked the changes that had been happening to Jenna since she traded the treadmill for her sewing chair and her healthy but time-consuming organic meals in favor of hot pockets and pizza rolls.�

�Well, I've been trying to figure out how to get back in shape without having to cut back on my workload,� Jenna explained, �and well, when I read the ad for this online, everything just sort of clicked; I just knew it would be perfect for me- you know what?� I'll just show you.�

����������� And with a smile full of mischief, she carried her prize into the next room, leaving me alone to wonder just what it was she was so excited about.� I had to admit, I kind of hoped whatever it was didn't help her to slim down too much; I'd enjoyed watching her once-trim figure growing more womanly over the last few of months.� Jenna's more sedentary lifestyle had brought some delightful developments, with her small breasts fattening into pleasing handfuls, and her narrow hips broadening until really had enough to hold onto when the situation called for it.� Her butt was starting to really round out as the pounds she was packing on sank to her bottom, and though I never would have imagined how much I'd enjoy it, even the growing softness of her belly was exciting when I draped an arm over her in bed and felt its warmth against my hand.� As I mused, I could hear Jenna tearing open the box and then, intriguingly, fetching the air pump and turning it on.� As the pump whirred away, I was tempted to sneak a look, but before I could, the pump fell silent, and a moment later she appeared at the door, triumphantly clutching a purple sphere nearly as wide as the door frame.

�See, it�s one of those exercise balls,� Jenna enthused, as if I had never heard of such a thing before, �It's exactly what I've been needing!�

�Wait, I thought you tried Pilates once and you hated it,� I pointed out.

�No, it's not like that, this is the one they make for lazy girls who are stuck at a desk all day,� Jenna said with a smile, �I'm going to sit on it while I'm working.� I read all about it you see; while a regular office chair is bad for your posture and gives you back problems and all sorts of other things, sitting on one of these keeps your body active and stimulated without you even having to think about it.� I'll be able to keep on working just like I have and still get back in shape before summer gets here and you have to see me on the beach with my cheesecake thighs.�

�Are you sure that just sitting on that thing while you work is going to do all that?� I asked doubtfully.

�Of course, it was all on the site I bought it from,� Jenna explained as she set the rubber ball down and sat herself upon it, �All day long, while I'm working, it'll be working; the description said it would do wonders for my figure almost immediately!� And not a moment too soon; if I don't make some big changes soon, I'm going to have to go up another bra size!�

�Oh, well, I hope it works for you then,� I managed, despite being untroubled by the prospect of Jenna having to go shopping for something in a 36D, �Hey now, what's that label say?�

�What labe- oh, sorry, I didn't even notice while I was blowing it up, �Jenna said as she noticed the unobtrusive white sticker on the ball, �It says, 'Caution, excessive use may cause dizziness, shortness of breath, soreness or exhaustion; do not exceed maximum rated weight, manufacturer accepts no liability for misuse.'�

�What do you suppose all that means?� I asked, still certain that this thing was a scam.

�Well, you know everything's got a warning on it these days,� Jenna shrugged, �It's probably just to keep them from getting sued if someone hurts herself using it like a toy, or falls off and gets a concussion or something.� And don't worry about the weight part; it's rated for up to six hundred pounds; can you even imagine me being that big?� That's like, four of me, I'd be a fucking whale; what would you even do with me if I was that fat?�

����������� I didn't say anything.� I had to admit, Jenna at six hundred pounds was a lot more woman than I'd ever thought about, but as I watched her sitting there on the exercise ball, bouncing gently, smiling as her blonde hair brushed against her shoulders, bobbing along with her smiling face, I found myself perversely taken with the idea.

�Well, so far this thing seems easy enough,� Jenna admitted, bouncing herself tentatively a time or two atop her new toy, �But I don't really see how this is going to give me enough exercise to make a difference in my- Mmmm-ohhh...�

�What is it hon, are you okay?� I asked as Jenna suddenly shut her eyes, her back arched slightly, her hands clutching fervently at the rubber sphere beneath her.

�What? Oh, no, I'm-I'm just fine,� she assured me, though still biting half-heartedly at her lower lip, while bobbing up and down a few more times, �It's just- Oh!- I just didn't expect it to feel this good!� I don't know why this is getting me all turned on.� Gosh, if sitting on top of this thing is this distracting, there's no way I'll be able to get any work done if I try to use it while I'm filling my commissions.�

�Well, if you're enjoying it that much,� I suggested, more than happy to encourage anything that got Jenna in an amorous mood, and more than a little taken at the sight of my modestly curvy girlfriend bouncing up and down so energetically, �You could always just keep it for play.�

�Oh, so you like it too?� Jenna asked, �Well, exercise is exercise I guess, but since I'm feeling less motivated to get any real work done by the second, I suppose I could always make this a bit more interesting for both of us.�

����������� Still wearing a mischievous smile, Jenna pulled her sweater over her head and tossed it aside, her inviting mounds now sheathed in only a coral-colored bra, looking nearer to overflowing their cups than I remembered.

�Mmm, it looks like I started not a moment too soon,� Jenna murmured, sounding far from worried about how ample her assets had grown over the past few months, �I feel like I'm one good night at the buffet away from spilling right out of this thing, not that I imagine you'd mind.�

����������� She stood, and for a moment I was worried that the sight of her modestly plump figure had driven more sensual thoughts from her mind.� Jenna gave me a wink, and I was soon reassured as she unbuttoned her jeans and shimmied out of them, her modesty from the waist down only protected by a matching pair of panties which, like her bra, looked as if they were well on their way to being a size or two too small, the soft lines of Jenna's body bulging out above and below their waistband, giving her the beginning of a muffin top.

�Oh, these pants weren't nearly this tight when I put them on this morning,� Jenna muttered as she stepped out of them and kicked them aside, before eyeing me playfully, �Now then, where was I?� Oh yes, I remember.�

����������� With a playful grin, Jenna settled down on top of the ball once more, her shapely legs splayed out across its girth, her knees bent until her calves pressed firmly against its lower hemisphere.� She leaned forward slightly, planting her hands again against the taut, shiny surface below her, giving me an excellent view of the gap between her full breasts.

�So, do you like this?� Jenna asked with a bewitching smile, as she bobbed up and down, small ripples of motion echoing through her chest and, though she was surely less pleased by it, through her plush little belly and well-upholstered behind as well, �Do you like watching your chubby little girlfriend bouncing like this, with my fat little boobs trying to spill right of my tight bra?� Mmm, it just feels so good, the way my whole body just rocks and flows like this.� I do hope you're not in any hurry to take the next act of my little show to the bedroom; I feel like I could do this all evening.�

�No, not at all,� I hastily assured her, �I could watch you all night if you felt like going that long.� Just as long as you don't wear yourself out too much before you're ready to come to bed.�

�Really?� Jenna said, as if she was surprised that this was such a turn-on for me too, �Do you just like watching me riding this thing?� Or is it because it's getting me all turned on and you already know how that story ends?� It's not something weird, is it, like you've got a secret balloon fetish or something you've never told me about?�

�No, no, it's just you,� I answered quickly, �I don't know, just watching you there in your skivvies, getting all warmed up is just really, really sexy.� And, I don't know, maybe it's because I'm looking down at you or just the way you're sitting right now or something, but your boobs just look, I don't know, bigger, somehow.�

�Well then, I'd hate to disappoint such an enthusiastic audience,� Jenna teased, cupping her wobbling handfuls and lifting them slightly for my approval before letting them drop against her chest, �Oh, I almost believe you're right and they are getting bigger; there's no way my bra was this snug yesterday.� Here, let me give you a real show.�

����������� Reaching behind her back, Jenna deftly unclasped her bra and gave her shoulders a little shrug, as her breasts slipped free.� There was no way it was just a trick of perspective; they were bigger than before, and not just a little.� Just last night Jenna had filled up a C-cup quite nicely, not huge by any means, but certainly more than enough to keep a fellow pleasantly occupied, but now, well, it was like something from a dream.� Jenna's boobs had swollen to the point that even hanging free they touched together, while they just looked so much fuller, as if they'd been pumped full of flesh but not allowed to stretch at all.� Her nipples looked almost painfully rigid, and the way that Jenna sucked her breath in sharply as her fingers grazed their skin told me they were just as sensitive as they looked.� I couldn't even tell if they had actually grown any bigger or if I'd just never seen her rosy peaks this stiff before.

����������� I knew I should say something, tell Jenna that somehow, her breasts were growing, but I was utterly enchanted, as if the same strange force that was filling her up had left me powerless to warn her.� Oblivious to how large her boobs had already become, Jenna set to really showing off her talents, rocking and grinding against the ball, eager to show me what I had waiting for me after she finished her workout.� Now freed from the restraint of her bra, her breasts swung and jiggled freely; I could hear the soft, slightly wet smack of skin against skin as they slapped against her chest.� Apparently being set free had made them even more receptive to whatever power was flowing into Jenna; as she bucked and shimmied with abandon her breasts, ever in motion, were growing at a breathtaking rate.� Before a couple of minutes had passed, they were big enough that they poured between Jenna's fingers as she clutched at them hungrily; a few minutes more and they were as broad as her chest, and obviously quite heavy from the way that Jenna's gyrations set them so deliciously aquiver.� I'd never seen a pair as perfect as hers; so lusciously soft and supple, and yet so round and full and plump that they couldn't possibly be natural.� I think I would have stood there, transfixed, all afternoon if she had kept bouncing away so lost in her own pleasure that she didn't even notice how palpably enlarged her breasts were becoming, but in the end, it was Jenna that broke the spell.

�Oh, jeez, now my panties are starting to chafe,� Jenna said, the discomfort tearing her from her playing around, �They're supposed to be the athletic fit and here just getting a bit of exercise makes them dig right into me!�

�Well, you may not have noticed,� I offered, still entranced by my girlfriend's blossoming bust, �But I think you've got bigger things than that to worry about.�

�What do you-� was all Jenna had time for as she glanced down at herself and got an eyeful of her very ample charms, �What the hell?� I'm fucking huge!�

�Sorry,� I explained, �I kept expecting you to realize what was happening and then, well, you just seemed to be enjoying yourself so much that I felt bad even thinking about interrupting.�

�How is this even possible?� Jenna asked, hefting her bloated breasts, their soft flesh spilling out between her outstretched fingers, �I'm enormous, like one of those women on TV whose hormones go crazy when they get pregnant or something and their boobs just blow up overnight until they're too heavy to walk, but this, this was like, fifteen minutes!� Just how big am I going to get?�

�It's okay; I think they've stopped growing for now,� I said, trying to keep Jenna calm, hoping that if she didn't freak out too much, she might be receptive to letting herself do a little more growing, �I'm not sure, but I think it only happens while you're using the ball, and since as soon as you took your bra off you started growing about five times as fast, maybe the more you bounce or jiggle or something the bigger it makes you grow?�

�Oh, so I don't have to worry about- Oh! So if I decided I wanted some more without being afraid I'd end up with a pair of tits bigger than my head, I could stop whenever I felt like I was starting to get too big, couldn't I?� Jenna sighed in relief, her expression brightening as the full implications struck her, �I mean, just riding this thing feels so good, I can't even describe it; it's like being right at the brink of climax and then just being pinned there while I just keep growing and growing; it's like every nerve in my body is tingling; the twins here are just so awfully sensitive now, I'm not sure I could force myself to walk away from this if I wanted to.� You wouldn't mind that, would you dear?� Having a girlfriend with such a massive pair of jugs that I get stares from a block away when we go out on a date, or having to order all my bras custom-made?� They'll probably be terribly expensive; it might be best to just wear one when I leave the house, and to just let my girls hang free at home, if you wouldn't mind having to watch me jiggle around in the evening while I worked on my sewing, or seeing me stuff them into my apron while I was cooking dinner?� Oh, and I've heard women with really massive tits get so awfully sore carrying all that extra weight around all day; why, you'd probably come home from work every night to find me laying in bed stripped to the waist, practically begging for you to rub me down and help me relax.� You wouldn't mind all that too much, would you, as long as it made me happy?�

�I think I could live with that,� I said, grinning broadly, �But before you start trying to give yourself an amazing pair of lower back problems, you should probably know that it's not just working up a sweat that's making your panties feel a little tight.�

�What do you-oh!� Jenna gasped, jumping to her feet and glancing downwards, realizing that everything south of her chest was beyond the horizon now, and using her hands to take stock of the rest of her body, �Oh my gosh, my hips!� My butt!� Just how big am I now?�

�Well, they haven't grown nearly as fast as your boobs,� I told her, getting a good look as Jenna turned in place to let me survey her newly-gained assets with more than a little pride, �But ad for that ball didn't lie; it is giving you an incredible figure.� You just- you're just so curvy, it's kind of hard to not just scoop you up right now and carry you off to bed and lock the door, honestly.�

�Mmm, well, you've been so patient watching me so far,� Jenna said seductively as she stepped a little closer, �Why don't you come have a taste before I make myself even bigger, just so you have an inkling of what you're getting into?�

����������� Jenna grabbed me tight, her breasts soft and full against my chest, swelling out around her arms as she mashed them between us.� My hands wandered lower, feeling how tight the waistband of her panties was becoming, how the soft curve of her hips swelled out above and below it at least an inch already, as if her body resented any attempt to contain her blossoming charms.� Jenna had always had a nice ass, well, nice by my standards anyway; she was big enough to really hang onto and always looked great with a tight pair of jeans stretched across her plump behind, but this was just something else.� Even if her boobs hadn't gained an ounce, a big, juicy rump like this would have made her a knockout.� She moaned softly as I grabbed a double handful of her butt and gave a hard squeeze.

�Ooh, I hope this isn't a dream,� Jenna breathed, �Every inch of me is tingling; I can't wait to find out how more of this feels.� Mmm, I've gotten fatter too, haven't I; I can feel my belly starting to slip over the top of my panties now that I'm standing up.� Please tell me you don't mind; please tell me it won't bother you if I turn into a bit of a fatty as long as my tits and ass grow even faster!�

�Hon, you can get as big as you want to be and I'm only going to love more of you- I mean, love you more,� I told Jenna, to her evident delight, �I always kind of liked you being a bit on the voluptuous side of things anyway.� If I were you, I'd be more worried about me cheering you on until you're so buxom you can barely walk, not that it'd bother me much if you had to spend more time in bed, as long as you didn't mind some company two or three times a day.�

�Mmm, now that sounds tempting,� Jenna smiled, fondling her enlarged breasts with anticipation as she released me and sashayed back to her exercise ball, her shapely hips rolling enticingly with every step, �So let's stop wasting time then; you just stand there and enjoy the show, and if I pass out from sheer sexual exhaustion, just roll me over so I'm not smothered to death by my own tits; I guess I'll just have to trust you won't take advantage of me while I'm all huge, sexy and helpless.�

�I don't know,� I admitted with a smile, �You lying on the floor in nothing but a pair of overstretched panties with your boobs swollen bigger than beach balls?� I'm just not sure I can resist that kind of temptation.�

�Beach balls, really?� I'm not sure I realized just how large your tastes happen to run.� Well, I suppose I'll just have to take my chances then,� Jenna said with a wink as she lowered herself back onto the ball, the band of her panties digging deep into her hips as she spread them out, �But then, a girl has to take a few risks if she's determined to discover just how much pleasure she can take.� I'll try to let you know when I feel like I'm pushing my limits, hmm?�

����������� Jenna was really going at it, now that this wasn't about getting fit anymore, and that every last tremble, every ripple that coursed through her body would make her bigger in all the right places.� The rubber skin of the ball creaked softly every time she came down on top of it, bulging out beneath her a split second before I heard the warm slap of her breasts colliding with her body.� After barely a minute of this they were noticeably fuller and their accumulating weight meant that such rough treatment was beginning to take a toll on Jenna.� Each breast was nearly as big as her head, and her moans of bliss were cut short as she winced each time the increasing weight of her swollen bosom was caught between the tug of gravity and the finite elasticity of her skin.�

����������� I could barely keep my hands off her.� Jenna was the most incredible sight I'd ever seen, and I was consumed by the idea of being with the transcendently voluptuous woman that she was becoming.� I could imagine being buried deep between Jenna's billowing breasts, squeezing her tight against me as I grabbed her lush, flaring hips, the sensation of her huge, jigglesome ass as she rode me even more feverishly than she was riding her ball.� The only thing that held me back, I think, was that every second I held back only rendered her figure more spectacular, and even in my delirium of desire, I knew sparing a few more minutes now would be well worth the paradise that awaited us when she had finally gotten her fill.

����������� Nor were the fruits of Jenna's efforts confined to her breasts; her belly was spilling over the top of her panties, and between its own amplified jiggliness and the way her breasts slapped against it heavily as they hung lower and lower, she was well on her way to becoming very plump and full-waisted indeed.� Jenna was fast developing down below as well.� She was working so hard that I could almost hear her already-generous ass ballooning with lushness.� Her hips spread out almost as wide as her bust, far broader than her shoulders, and as Jenna kept going, lost in her lustful reverie, I saw that her legs too had begun to fill out, as she had bounced her slightly plump thighs to the point where they were fat enough that they wobbled at the slightest provocation, which as with the rest of her figure, seemed to be the point at which their rate of gain accelerated dramatically.

����������� This was nowhere more obvious than in Jenna's breasts; even while I had been admiring the rest of her, it looked as if they'd had another ten pounds of fat pumped into each of them, the unbridled jiggling and quaking that this brought only forcing them fill that much quicker, so rapidly I could see them fattening with every movement of her body.� Jenna flinched each time they slapped against her plumpening belly, the sound growing louder each time, a sheen of sweat forming across her expansive bosom as Jenna's breasts grew pinkish underneath, until I worried that if she kept punishing herself this way she was going to have some very painful bruises tomorrow.� It must have finally been too much for her to take, because Jenna stopped bouncing, sighing with relief as her breasts wobbled to rest in her lap.

�Oh, that's just too much; I can't keep this up,� Jenna admitted, trying to catch her breath as she cradled her swollen breasts.� They were far too large and heavy for her to really support them anymore, the best she could really do was stabilize them a bit, so that they didn't jiggle quite so wantonly, �Oh, they're just getting so tender; every time I come down they feel like I've been slapped; if this wasn't getting me so turned on I can hardly see straight, I don't think I'd be able to keep it up.� I never thought that feeling so good would hurt so much.�

�Well, what if you gave them a little more support?� I offered, �We could make some kind of sling or something out of a sheet so you wouldn't bounce around so much or, well, I'd be happy to help hold them in place if you said 'please'.�

�Mmm, that's quite an offer,� Jenna said with a come-hither glint in her eye, as if she was tempted for the moment to just enjoy what she had, but before she could stand to accept, her thirst for more prevailed as she gave a shiver and gazed down at herself, �No, no, that wouldn't work.� The more I bounce, the bigger I grow, and if we keep my tits from bouncing around, the rest of me would keep expanding just as fast as before.� I don't mind getting a little pear-shaped if it means I'm going to have monster boobs, but I could never be satisfied with a humongous ass and a belly that reaches my knees if I didn't have a pair of mouth-watering melons to round things out.� Oh, and just look at how plump my nipples have gotten; it feels like they haven't grown, they've just been inflated; they're just so tight I can hardly stand it.� Here, you've been a good boy; come feel me.�

����������� Jenna arched her back and raised her crossed arms a slightly, lifting her swollen breasts towards me.� Her nipples were exquisitely distended, as if the two little tips I was so intimately familiar with had been pumped up to the size of ripe grapes without any thought as to whether they could endure such raw treatment, however tantalizing the consequences might be.� As tenderly as I could, I gave her taut peaks a pinch; Jenna let out a cry of ecstasy that wracked her body, throwing her head back as she screamed, shuddering as she quivered with ill-contained bliss, the sudden movement forcing her breasts to swell a little more, her tightly-stretched areolae being pulled out further across the expanding area of her pale globes.

�Oh- oh my- That was incredible-,� Jenna gasped, vainly trying to support her breasts as if they were liable to explode from the sheer volume of pleasure coursing into them, her entire body trembling with desire, �Okay- I- I can't stop now; you have to help me keep going-�

�Are you sure you're ready for more?� I asked, my mind ablaze with at the thought for Jenna becoming even more luscious, even more insatiable as she grew; but still I was worried about just how much might be too much for her.� She was already so consumed by her thirst for more, and I worried things could get dangerous in a hurry, �I mean, you wouldn't have to stop forever, you could just call it a night.� You could get some rest, or maybe we could have a little fun and take your new curves for a bit of a test drive if you felt up to it, and then tomorrow you could come back for another round or two; there's no reason you have to force yourself to go from cute to colossal in one sitting.�

�I know I should; my boobs are already going to be so terribly sore tomorrow after what I've put them through,� Jenna admitted, though she had already begun bouncing again, albeit much more gingerly, �But I can't stop now, not while I feel like this!� I can't even describe it to you; I'm already so full, so supple that even sitting still, just trying to keep my balance I can feel myself trembling all over, every last shudder making me that much more ravishing.� No, I can't quit; by the time I'm done I'm going to have the biggest tits in the world, and I'll need your help to take care of them, if you're feeling up to the challenge?�

�Well, I guess it there wouldn't be much point in arguing?� I asked Jenna, brushing my worries aside as I watched her sumptuous figure becoming more enlarged while she talked, �You just tell me what you need handled.�

�Hmm, don't worry, lover,� Jenna said, running her tongue along her lips, and spreading her thighs further apart to give her belly more room to grow, �By the time I'm done there'll be so much of me to handle you won't even know where to begin, though I think I might be in a position to offer a few suggestions.�

����������� Even though her pace had slackened, Jenna looked like she might be growing faster, as if her body, especially her immensely fattened breasts, was just so supremely jiggly that even the laziest workout was bound to pack more pounds into her.� She was getting so winsomely fat I could barely believe she was the same slightly chubby girl I had come home to not an hour before.� The waistband of her panties was invisible now, buried deep in the fulsome rolls of her fertile hips, now wider than the exercise ball itself, while her belly, fattened to the point where it rested on her lavish thighs and spilled down between them, protected what little remained of her modesty.� Her legs had become so sleek and full of flesh in fact, that I wasn't entirely sure she'd be able to move at anything more than waddle once she was finished, while the weight of her breasts was almost entirely borne by her belly.� Like a pair of overfilled water balloons, they had begun to surrender their splendid roundness; they hung from her chest quivering, ripening until they were as big as watermelons left too long on the vine over a wet summer.� Another inch or two and they'd be resting in her lap, well, resting in whatever her belly hadn't already claimed.� Jenna's nipples were getting indecently tight, throbbing as they grew more and more enlarged, pointing more towards the floor with Jenna's every movement as the gallons of fat she carried within her breasts stretched their supple skin as she forced her body to drink in pound after pound.

����������� Awash with bliss, Jenna only gave a start after a snapping sound that came a split second before her juicy hips surged outwards several inches wider.

�Oh, well that took long enough,� Jenna said with a lascivious grin as she worked her hands down between her belly and her thighs, tugging the shredded remnants of her panties free, �I'm surprised they held out this long, really, but now that there's nothing holding me back down there, I bet my belly and my ass are really going to start really big.�

�Is that a problem?� I asked, not seeing the downside, aside from the fact that Jenna looked to be rapidly approaching the point where she would rubbing the paint off our doorways as she squeezed her lush rump from room to room.

�Well, it's not that I mind having a bit more sand at the bottom of my hourglass,� Jenna admitted, giving herself a slap on the derriere that touched off such a tsunami of jiggling that she probably put on another five pounds right then and there, �But I would like to keep my belly from getting as fat as I want my boobs to be.� I kind of like the idea of getting really fat; honestly, now that's it�s happening to me, it's a huge turn-on, feeling all these rolls growing and swelling, lifting my tits up until I'll be able to just bury my face down between them, the way they're weighing down so deliciously against my lush thighs, pressing me against myself in all sorts of new ways.� I think it might even be fattening me up inside too; I just feel so full and squishy down there now, like all the parts of me that give me pleasure are just swelling up fatter and tighter and juicier.� I'm almost tempted to take you to bed right now, just to find out how it feels to be fucked at this size and make sure that I haven't gotten so full I can't fit you into me anymore.� Almost.� And besides, I'm so awfully wet right now; I feel like I could take you even if you were twice as thick.�

�Okay then,� I said, inwardly delighted at how every ounce Jenna gained was making her more lascivious, every ounce she gained leaving her more helplessly sodden with desire, �How can I help?�

�How indeed?� Jenna purred, squeezing her breasts between her arms so that they looked even more magnificent, �Well, If I keep this up I'm going to have an ass so huge I'll need two of these balls just to keep my balance and a belly so overstuffed that you'll have to roll it out of the way before we have sex- well, I guess there are always other positions, so it might not be all bad- but still, if you give me a hand with my girls here, so that they're the only part of me bouncing and jiggling, maybe they'll keep on swelling up like a couple of rising weather balloons and I won't get any more ludicrously voluptuous down below than I already am.� Besides, if my belly gets much fatter than this, I won't be able to reach myself, and you'll have to take care of me whenever I start feeling needy, which might not sound too bad for you, but you'd be surprised how much it happens while you're off at work.� I'll just end up laying in bed touching every inch of myself within reach, working myself up into a lather, just thinking about you doing the kinkiest things to me- you'd blush if I even described them- growing so full with unsatisfied desires that I'd feel ready to explode, and I'd just hate for you to have to come home and deal with that every night.� As it is, I feel like my libido is already going to be keeping you plenty busy with feeding my appetite, though I think you'll find the rewards more than ample.�

�Where do I start?� was all I could say, already kneeling in front of Jenna, her massive mammaries heaving mere inches from my face, heat radiating from her skin.

�Oh, you just do whatever you're in the mood for,� Jenna murmured, indecently pleased with herself at having brought me to my knees, �Squeeze them, suck them, tug on them.� I know you're probably worried because of how terribly delicate and overfilled my tits are, but I can take it.� You can be rough with me; I'm a big girl.� You could slap them just like you were spanking my fat ass, or pinch my poor nipples so tight I'll faint clear away.� Just remember, everything you do to my boobs, anything that makes them quiver or quake, will only make them bigger, inflating them with more tender, trembling flesh.� Don't hold back; I want you to just go wild with my tits, and not even notice how backbreakingly heavy they're getting, or worry when you hear my skin stretching and creaking as they get larger and larger, filling up with gallon after gallon of fat until I can barely move.� Don't stop until I tell you, until they're so huge they weigh more than I do, and I am a very full-figured girl by now, lest you forget; I don't just want bigger breasts than any woman alive, I want the biggest breasts ever.� I want my boobs so obscenely swollen with fat that I won't even be able to leave the house; I'll just work on my projects all day, my sewing machine nestled snug in my cleavage; I'll have to be very careful of stray needles, I think, and you'll come home to find me so very eager for attention that I won't give you a moment's peace until you've taken me to bed and worn me out properly.� Don't make me ask again; grab a couple big, wobbling handfuls and don't you dare let go until I'm begging for mercy.�

����������� I never could say no to Jenna.� She gasped, her body growing tense as I grabbed as much of her tremulous bosom as I could and squashed her breasts together as hard as I could.� She gave a little cry of pleasure as I roughly kneaded her bloated melons, not bothering to stifle a scream as I took one rigid, throbbing nipple in my mouth and began to suck.� Jenna's breasts heaved and surged, at the mercy of the sea of jigglesome flesh within them, her tides of excess growing by the second, the rimpled skin of her nipple rasping wet and hot against my tongue.� As I clutched at her opulently distended breasts, I could feel them growing bigger, their skin stretching and slipping against my fingertips as they were laded with more.� When I opened my eyes for a moment, my face pressed close to the yielding globe which loomed before me, I saw Jenna's areolae were being drawn out further and further, now the size of tea saucers and developing a sort of a wan, diluted pinkness as Jenna begged me not to stop.

����������� I made sure that Jenna's other peak didn't want for attention (heaven forbid that Jenna end up with one breast less gigantic than the other) and set to work devotedly.� Her breasts were each more than a foot across by now, resting heavily atop her belly and spilling out across her seductively full hips.� As I tried to heft and tug at her nearest billowing globe, determined to force Jenna to gain more as fast as the ball could pump the pounds into her willing form, I found it hard to lift even one of her breasts.� Each had to be at least fifty pounds already, and impossible to get a grip on unless I seized her by the nipples and lifted them like two sacks full of jello, which seemed like too more punishment than she could take right now, no matter how loudly she claimed otherwise.� As Jenna arched her back and ground herself against the lust-slickened rubber beneath her, it was already clear that her plan to confine all further growth to her bust left much to be desired.� In her lust for more, bucking and writhing with ravishment, she was only pushing her body, already immodestly jigglesome, to bounce all the more.� Just a glimpse was more than enough to reveal that her ass was fattening nearly as fast as her breasts, the ball bulging out more and more as Jenna soaked up its power like a sponge.� I could feel her legs becoming softer and fuller, from her plump ankles to her winsomely fertile hips, while with each second that ticked by Jenna's ample belly lifted her bosom more proudly, her cute belly button growing and deepening until it was lost between two ballooning rolls of fat.� But she wanted more.

�More, please, I need it faster,� Jenna gasped, her blonde hair soaked with sweat and clinging to her face, her body glistening in the evening light, �Suck them both, make me come harder!� Make my tits so huge you can lay on top of them while I suck you off!� Oh, I'm so wet I feel like I'm going to slide right off this ball, or maybe it's just going to slide right into me.� Please, do anything you want to me, anything, just don't stop.�

����������� Just pulling Jenna's nipples close enough together to do this was a herculean task, with such a massive supply of tremulous flesh between them, even mashing her boobs together as hard as I could still left me with a gap of six inches to close.� Being so violently fattened in such a short time had wholly overwhelmed her breasts' unnatural roundness, Jenna's nipples now pointing downward, her overstretched areolae now brushing against her plump knees, her bosom pendulous with excess.

�Oh, come on, you need to suck them!� Jenna begged, panting as my rough handling inflamed her desire all the more, �You can't just tease me like this; I can feel them blowing up but it's not enough; don't just play with them, make me scream!�

�I'm sorry, they're- they're just too huge,� I admitted, still stroking Jenna's massive breasts, �There's just too much of you now; they're so heavy, I don't think I can stretch them far enough to reach.�

�Okay then,� Jenna said, her eyes shut tight as waves of pleasure continued to surge against her from within, �Get out of your pants.� You're going to fuck my big, bloated tits, and I want it good and hard.� I want you to make them bounce and jiggle so much that by the time you finish they'll weigh double what they do now, and you'd better not be come until they're so exquisitely swollen that I'm ready to burst.�

����������� I was undressed before Jenna finished talking; I'd been burning to have her like this since the instant I realized she was growing.� I stood before her, her huge breasts heaving as she fought for breath, the strain of her untamed desire and the massive weight of her bosom hanging against her chest forcing her to struggle for air.� She was so sensuous already, the pale skin of her heavy breasts moist and gleaming, and she gazed up at me, drunk with longing as she pressed her hands to the undersides of her vast breasts, desperate for more, despite already being so delicately overfilled that they needed far more support than she could give them.� I had kept Jenna waiting long enough; I stepped forward and thrust myself in between her lush melons as deep as I could, making her envelop me until her yielding flesh resisted, until I felt like I could almost drown within her body.

����������� Jenna cried out in ecstasy; her breasts eagerly surrendering to allow me in and then just as willingly letting me go so that I could plunge between them again.� Jenna had always been sexy to me, but I had always dreamed of taking her this way; her breasts, however pleasing they had been before, had always been just a bit too small for this, but now, with her so magnificently endowed that I felt that if I could go twice as deep she still would have received me easily, it was better than I imagined.� The way she squeezed me was almost indescribable, how many countless pounds of quivering flesh pressing in together, and yet her body remained sublimely yielding, and I felt like I could go on like this for hours.� I found my rhythm, Jenna's breasts rolling and swaying with liquid submissiveness, surging against me a split second after I withdrew, and then slapping against her soft body a moment after I plunged between them to the hilt.

�Oh, yes, this is what I've been dying for; give me more!� Jenna screamed, her breasts now so swollen that when they rolled against her body they nearly rose to her face, �Oh, they're filling up so fast now, it's such a strain to take it all in at once; come on, give it to me harder, faster, I want to hear my tits groaning as you load me with more, I want to be caught between wishing you'd never stop and begging you to come because my poor boobs are so crammed with fat that every time you slide between them I feel like they're going to burst!�

����������� I grabbed Jenna's shoulders to pull her in nearer.� Her entire body had been saturated with fullness; even her arms were now so thick that I wondered how she'd be able to squeeze them into the sleeves of even the roomiest sweater.� Glancing past Jenna's head and down her back, I witnessed how absolutely her plans keep the rest of her figure from expanding any more had backfired.� Her ass was tremendous; I couldn't even see the ball anymore, just the point where the gentle curve of her back was replaced by vast expanse of lushness more wobblesome and supple than her bosom, if such a thing is possible.� Along with her expansive hips, Jenna's ass bulged out around her fully twelve inches; my concern for how Jenna planned to walk with such a plush behind falling before my desire to see just how much more weight I could make her gain.� Instead of a nascent muffin top, Jenna now had a deep roll where her belly lapped over her hips.� Her breath came hot and ragged against my chest, as her belly finally fattened to the point that it slapped against my legs as I took her.

����������� I could feel her breasts growing larger, heavier as I went; each time I buried myself in her bosom, I felt her billowing body roll against me harder, her skin stretching against mine as she grew.� Jenna's bust was fully six inches broader now than when I'd first slipped into her receptive depths, and it was beginning to weigh heavily upon her.

�Don't stop; they're getting so heavy, so full I can barely stand it,� Jenna gasped, �They must be twice as heavy since you started fucking them; you're just pumping me up so fast I think I might faint.�

�Do you want me to stop?� I asked, pausing for a moment and marveling at how, once they stopped swaying enough that I could get an idea of just how productive my efforts had been, Jenna's boobs were almost incomprehensibly massive.� Looking down at the ocean of smooth, creamy flesh lay between us I could hardly believe how much larger her breasts had become in just the last few minutes.� I could see that this might be growing hard for her; I wouldn't have been surprised if her breasts were pushing a hundred pounds each, and I wondered how she'd even be able to stand up without her lap to support them, or whether her belly would end up so huge that they rested on top of it; the thought of Jenna needing help to carry them around filling my mind with all sorts of possibilities.

�What? No, don't stop!� Jenna shouted, her voice husky with desire, �Keep giving it to me, just- well, don't feel like you need to wait for me, I've already come so many times I can't count; when you're ready, just go ahead.�

����������� I did, Jenna's ballooning breasts soon slapping rhythmically against my body as I pounded away at her mammoth bosom.� Her rate of growth was increasing; I could hear the squeak of wet rubber as her ass swelled against the ball.� Even her face seemed to be growing rounder now, to the point where she was starting to develop a double chin, like every part of her that could bounce in even the smallest degree was fattening up.� I was amazed that I was still going; I would have guessed I'd have been able to keep this pace for about five seconds before I came, and though I felt myself getting harder with each thrust into Jenna's welcoming cleft, I was sure I could last just a little longer.� I wondered how much weight each push added to Jenna's boobs.� One pound, maybe two?� As I heard the ball protesting more emphatically, I remembered the warning; could she really be pushing five hundred pounds by now?� I couldn't believe it, yet as I looked down at Jenna whimpering with pleasure, her chin held high as the tide of her bosom rose higher and higher, it began to seem very possible indeed.

�Okay, I think I've finally had enough; you need to come now,� Jenna rasped, her voice ragged from screaming, �I never thought you could last this long, but they're getting too full now; I don't know how much more I can take.� Oh- they're just inflating like balloons now; I just feel so tight, I can feel them stretching- I know I told you not to come until they were about to burst; but I think I'm getting awfully close!�

I quickened my pace, trying to hasten my climax, but this only set Jenna's sumptuous endowments rolling and jiggling more violently.� Her taut skin strained as her body labored to contain the prodigious volume of her breasts, their weight growing more and more oppressive as they were engorged with gallon after gallon of quiversome flesh.

�Please, you've got to come now,� Jenna cried, a note of fear entering her voice, �I'm too big; I can't hold this much- my tits are going to explode!�

����������� Her desperation must stroked some perverse desire of mine, because Jenna's pleading finally did it.� I shot myself in deep between her brimming breasts, a moment drawn into eternity as she sobbed with bliss and relief before, exhausted, I staggered back a couple steps, leaving Jenna heaving like a bellows, gasping for air, while I stared at what we had done to her.

����������� Our last few frenzied minutes of passion had come with massive consequences for Jenna.� Her bosom was swollen to at least three feet across, and quite full in proportion.� I could see why she had panicked; I could see blue veins just below her skin, tracing across her globes as her body worked to nourish and feed her overfilled breasts.� They looked exhaustingly heavy, quivering with Jenna's every breath, resting on her knees and spilling out beyond them by several inches.� Her areolae were wider than my hand, her nipples were so seductively plump that between their fullness and the way her udders hung full and heavy from her chest, I could almost imagine Jenna being full of milk.� She was already the very picture of fertility, her body resplendently overfilled; it was easy to picture her swollen mammaries becoming heavier yet as they filled with cream, their awful burden only growing as they grew distended with richness, hanging lower and lower as Jenna begged me to help relieve the pressure building inside of her, her watching with increasing alarm as gallon after gallon of milk filled her to the brim, white streams leaking from her nipples as the load within them grew, her need for release becoming more urgent with every second that slipped by; Jenna fighting in vain to reach her throbbing nipples, her efforts only succeeding in forcing milk to spurt erratically from them, far too little to stem the tide that was distending her massive breasts far beyond her limits, a whole dairy's worth of milk contained within her straining breasts, pinning her to the floor as I waited to see how much more she could hold-

�Hey, you can stare at my boobs all you want later,� Jenna said sharply, bringing me back to reality, �Right now, you need to help me get off this thing.�

�What do you mean?� I asked, still a little dizzy at the realization of just how tantalizing Jenna had become.

�This ball, it makes me bigger when I bounce on it, remember?� Jenna chided, �And look at me, I'm so fat now that even if I try to sit still it still takes every last wobble of my bloated tits and my fat ass and pumps that much weight right back into them.� Please, my boobs are already too full; they're getting really tight and I don't know how much longer I can take it.� Please, help me up.�

����������� Jenna held out her arms; even her fingers were chubby now, her arms gaining girth along their length, until just below her shoulders they were at least as big around as her thighs had been before.� I held her hands, trying to focus on getting her up and not getting distracted by gently quivering globes laying so invitingly against me.

�Okay, one, two, three, now!� I said, almost shouting the last word as I hauled Jenna upright.

����������� Struggling to support several times more weight than she was used to, Jenna gave it her all, straightening her knees, lifting her overstuffed ass off the ball, but we were both so exhausted by our recent revels, and with her unprepared for just how much she was carrying now and me not ready for how forcefully her soft, ponderous breasts were trying to push me off my feet, just as I felt we were going to make it, my strength failed, Jenna lost her balance, and her hands slipped from mine as she fell, hard, back onto the ball.

����������� The result of this sudden, violent impact sent shock waves rippling through her body, and no sooner had I heard the smack of Jenna's ample seat against rubber than her body trembled as she was forced to gain at least another hundred pounds in a few seconds.� Jenna clutched at her breasts helplessly as they inflated like balloons, fat surging into them; her eyes shut tight and her jaw clenched as she endured the debilitating jolt of pleasure and discomfort.� The color of their skin grew milkier, her areolae stretching out alarmingly.� The rest of her figure was spared only in comparison, with her ass billowing out another couple of inches behind her, her hips flaring out until I thought she'd be lucky to walk at all after this, and her breasts rising higher as her belly, though hidden beneath them, grew still more lush and self-indulgent, the ball objecting loudly at the added burden.

�Oh-my tits- They're gigantic!� Jenna cried as she finally recovered enough to see the results of our attempt, �If this didn't feel so incredible, I think I'd be crying right now; there's no way my boobs can take this much all at once.� Here, you have to try again; you need to help me up before I get any bigger!�

�Hang on,� I panted, still recovering, �We're not going to have better luck now that we're both even more tired and you've put on another hundred pounds or more; please, just give me a second to catch my breath and figure out a better way to do this.�

�Okay, but hurry, please,� Jenna sighed, anxiously caressing her breasts, now so immensely swollen that they pressed against her neck even when she was sitting still, �I'm just so obscenely bouncy now; every second we wait is pushing them to gain more; they're getting so heavy I don't know how I'll be able to support them.�

�Alright, let me think,� I said, pacing around her as I tried to figure out what to do while keeping Jenna from freaking out any more than she already was, �Well, what if we tried it from behind this time?�

�You never do stop thinking about sex, do you?� Jenna shot back with just a hint of a smile, �You get me off this damn ball before my boobs swell up bigger than the Hindenburg and you can ride my big ass all weekend long if you like.�

�That's not what-,� I countered, pausing for a second as her words sank in, �Well, since you brought it up, I think I'm going to enjoy holding you to that promise once we're out of trouble here.� What I meant is what if I stand back here and try to lift you up, and as soon as you feel like you've got your balance for even a second, you just try to fall forwards; it might be easier than standing up and walking; you won't have to keep your balance.�

�Falling?� Jenna asked anxiously, �But my tits are already so fat, and they're awfully tender just sitting like this; I can't even think about what would happen if I fell on top of them.�

�Well, give me a minute then,� I said, watching Jenna's curves growing slowly, but visibly, more generous as we argued, �I'll go drag the mattress in here, would that help?�

�Ooh, no, we don't have time for that,� Jenna admitted, �I can't sit here watching my boobs swell up while you gather up every pillow in the house for me.� Okay, let's do this.�

����������� I leaned forward and hooked my hands under her arms, took a deep breath and wrung every ounce of strength I could into lifting Jenna.� This time it was going to work.� Gathering her strength Jenna rose from her seat.� Just a few more inches forward-just a couple now-she'd just need to reach the tipping point and then gravity would do all the work.� Suddenly Jenna flailed her arms wildly as if she'd just stepped on ice.� She lurched forward, but then with a jerk pulled herself backwards, falling back onto the ball even harder than before.� The view from behind as her body endured the consequences of her fall was breathtaking.

�No- Please!� Jenna cried as she struck, but it was too late to stop the ball from lading her overfilled body with more.

����������� I watched helplessly as the ball bulged out beneath her so dangerously that I was sure it was going to pop, transfixed by the sight of Jenna's figure absolutely ballooning with fat.� Her ass, already so broad that I wondered if she'd even be able to get out of the living room, was crammed with lusciousness.� Pale and soft and already trembling with overindulgence, it rapidly gained enough to be fully six inches wider in nearly as many seconds, so magnificently voluptuous now that Jenna's lower half dwarfed the ball which had recently looked so big compared to her body.� I watched her belly swelling larger and larger as fat poured into her, her plump arms being pushed further apart as she expanded, her generous love handles blossoming into quiversome rolls as her body was glutted with lushness.� Even from behind, I could see Jenna's breasts growing uncontrollably.� They wobbled like two overfilled water balloons as they spread wider and wider, her bosom swiftly becoming, much like her sumptuous behind, fully six inches broader than it had been in less than a minute.

����������� As Jenna's growth slowed and I climbed back to my feet, I was amazed at the boundless slope of creamy flesh I beheld as I looked down over her plump, squeezable shoulders and saw just how titanic her breasts had become.� Everything in front of her was simply buried under them.� I knew her belly had to be immense by now, but they covered it easily, with hardly a sign that it lay beneath them.� Her cleavage was a chasm so deep I felt like I could get lost in it.� I couldn't even see her nipples from where I stood, no matter how full they might have become, they were hidden beyond the horizon of her two heavenly spheres.� Jenna's breasts had risen until they pressed up against her chin, well, her upper one at least; her face had become so radiantly round that I wouldn't have been a bit surprised to find out that she sported more than just a double chin by now.� Her bust now spread four feet across if it was an inch, her breasts larger than overfilled beach balls and enchantingly heavy.� As I walked around to face Jenna, amazed at just how much of her there was, I saw her palms raised ever so carefully beneath them, as far out as she could reach, as if she hoped to lend her engorged breasts some semblance of the support they needed so desperately.� Jenna had gained much more this time.� If my guess about a hundred pounds from her first fall had been close to the mark, then surely this latest effort to free herself had poured another hundred and fifty into her.� As if she had been holding her breath, Jenna let out a long, slow sigh, before finally looking down at her spectacularly overfilled figure.

�Oh my- They just- it's like they go on forever now.� Jenna breathed, burying her chin in her bosom as she tried to look down and take stock of just how utterly immense she had become, �I- I never knew I could take all this; there's just so much of me now; like I can't even process where everything I feel is coming from.� Ooh, and every inch of it feels so tantalizingly sensitive.�

�Are you- are you okay?� I asked, finding that even though my alarm at Jenna's predicament was growing, it seemed to be having trouble keeping up with my curiosity to see if she couldn't bear to grow just a little more voluptuous.

�I just feel so, so full,� Jenna sighed, gingerly caressing her breasts, �My boobs feel like a couple of water balloons being filled by a fire-hose; just sitting here is making them heavier; they're so fat that I can hear them sloshing.� Just breathing makes them wobble, and it's getting me so turned on that it's all I can do to stop myself from just bouncing away until I come again, but there's no way I could take more than a few seconds of that kind of abuse, not in this condition.� Please, you have to help me.�

�Just tell me what to do,� I said, looking down at my sumptuously fattened girlfriend, with no idea what to do next.

�Please,� Jenna said beseechingly, �I know I must weigh like, half a ton by now, but try one more time.� I'm just too big now; I can't begin to do it by myself; I'm just not strong enough to lift all this weight, and I can feel myself getting heavier by the minute.� Please, there's no other way.�

�Well, what if you just sat there until the ball popped?� I suggested, despairing of being able to help with even a fraction of Jenna's weight, �I mean, it said it was only rated to five hundred pounds and, well, if you don't already way more than that you've got to be getting close.� Why not just sit there and enjoy the ride for a few more minutes until it blows and then we can work on getting you up without worrying that one wrong move is going to pump another hundred some pounds into your body?�

�Mmm, it is a tempting idea,� Jenna sighed as she stroked her vast bosom expectantly, �But what if they rated it that low just to keep from getting sued or something?� I could be here for the next hour, just getting fatter and fatter, watching helplessly as my boobs get even more enormous.� What if I really do reach my limits before the ball finally gives way?� If you're worried about pulling me up now, there's no way you'd be able to help me if I were twice this size, my tits so obscenely swollen they were seconds away from bursting.� And if it came to that I think I'd be even less help than I am now; as uncomfortable as it is to feel myself expanding like this, I've got to admit it's getting harder and harder to focus on getting out of this and instead of how horny this is making me.� No, if we're going to do this, it's got to be now.�

�Okay, one last time then,� I agreed, �But no promises; I can only do my best.�

�Don't worry, love,� Jenna said hopefully, �After we get through this, I'm going to thank you so hard for taking such good care of me.�

����������� Jenna held out her arms, her fingers now barely reaching past her breasts.� I held her hands tightly, bending my knees low so that I could use my whole body in this one last attempt.� Just above the horizon of Jenna's two quaking globes, our eyes met, and then she struggled to stand as I pulled with all my might.� After a moment, I felt her rising, improbably.� Inch by grueling inch Jenna rose from her seat on the ball that had wrought such changes to her body.� As she finally neared the point where our first effort had failed so spectacularly, I realized I couldn't just pull her up; once she pressing against me, there was no way I'd be able to pull her further, so, not loosening my grip, I threw myself backwards, hoping that my weight, however modest compared to hers, might be enough to bring her forward those last couple of inches.� Even if she ended up falling on top of me, I figured, she'd be out of danger and, well, no matter how much she weighted now, she was certainly well-padded enough to make the blow an easy one.

����������� It worked!� As Jenna finally got her feet under her, I lost my hold on her, falling to the floor.� The view from below was breathtaking, her belly bulging out from her body like that of a goddess, its lowest curve hanging like a crescent just above her knees, while resting upon it was the most spectacular vista of underboob I could imagine.

�Oh, yes! We did it!� Jenna shouted, her voice sounding strangely distant with such vast and pleasant mountains suspended between us, �I knew we could-whoa-oh!�

����������� In her excitement, Jenna had forgotten just how unsteady she had grown, and how very unequal her legs were to the task of carrying so much weight, and that she was very nearly exhausted by now, so while I was still working to stand up myself, I watched in mingled awe and horror as Jenna lost her balance and toppled backwards, right onto the ball.

����������� As her overstuffed ass stuck the rubber the room echoed with a slap like a lightning bolt.� So much weight, falling from such a height, overwhelmed it, the rubbed groaned loudly; her breasts were already beginning to fatten.� A moment later an explosion tore through the air; the ball had finally met its match, and after hanging in the air for a split second, Jenna fell to the floor.

����������� We never figured out whether it just took a few moments for whatever spell the ball had over it to dissipate after its destruction, or whether popping it somehow released whatever weird magic it contained in one final, fattening burst, but either way, it all poured into Jenna's all-too vulnerable form, injecting all its energy into her seat before bubbling up to her apex.

����������� Her ass ballooned beneath her, countless gallons of fat flooding into it before she even hit the floor.� Jenna was already staggeringly huge down there, but in the course of a few seconds, everything from her waist to her hips was glutted until I wondered if she wouldn't spill over the sides of our bed after this.� Her hips blossomed out so lush and full now, I was sure I couldn't reach even halfway around them, while her ginormous ass bulged out all the more at being forced to carry all this weight, the dimpled skin of her cheeks compelled to take in more and more, until she looked like some ancient fertility idol, but fattened to even more glorious proportions.

����������� Though hidden beneath the bulk of her bosom, I could see that Jenna's belly was enduring similar misfortunes.� Her thighs, sleek and invitingly full, were forced apart by expanding belly.� As its bottommost curve inched lower, I saw her bellybutton appear below her lap-filling breasts, growing lower still as Jenna's belly expanded to ravishing lushness.� It wasn't simply hanging lower either; I could see that her belly, despite her rolls, was stretched taut by the sheer volume of fat surging into her.� Even with her legs spread wide to accommodate it, it finally lapped over her parted knees, while below them it simply grew bigger and bigger, as if, unconstrained from below, it might well keep on expanding until Jenna could use it like a waterbed, though already it was creaking from the strain, jiggling weakly as more was forced into it.

����������� For all the excesses which the rest of her body endured, Jenna's breasts still bore the worst of it.� Even as unbearably massive as they were, they gave a start as this last burst of power gushed into them.� Her breasts looked like they were gaining ten pounds a second, and all that Jenna could do was accept it, growing more divinely overladen and waiting submissively for more.� Her areolae, straining with far more than they were meant to endure, were split with stretch marks, shooting from around Jenna's pulsing nipples; the aftershocks of this sudden surrender sending ripples through her mammoth mammaries as they gained another few inches, growing massively fuller in an instant.� Jenna gasped; the spreading wave of motion echoed to her peaks again and her nipples, already swollen to several times the size of her once pert little nubs, doubled in size, distended to the size of overripe strawberries.� Her areolae now bulged beyond the curve of her colossal breasts, their tender skin yielding more as the burden behind them grew.� Jenna's bosom now spread fully six inches broader than before this last ill-fated attempt, overwhelming even her lush belly as they ballooned past her knees.�

����������� Jenna's eyes were closed, her breath labored as she struggled for enough air to sustain her obscenely over-endowed body.� Jenna moaned and whimpered with desperation, her own body heedless of her wishes, helpless to stem the tide pouring into her, only able to wait compliantly as her breasts grew larger and larger still.� Her nipples throbbed from the pressure mounting within her.� The unspent energy inside of her seemed more unstable now; as it spent itself to the last, Jenna's breasts were wracked by one last punishing surge of growth.� Already fattened beyond reason, exquisitely heavy with pliant flesh, in the course of a moment they looked as if they were each laden with another hundred pounds, creaking so ominously that I had to resist the urge to pull away.� It was more, hopelessly more than Jenna could hope to withstand; her breasts, which had barely an hour ago been small enough to rest in my palms were now inflated with so much fat that each one had to weigh at least a couple hundred pounds, and Jenna was acutely sensible of every last ounce.� It was just too much; she was already filled so unbearably beyond her limits, her breasts submitting as they were pumped full of more and more and more.� I couldn't tell any more if the look on Jenna's face was orgasmic bliss or excruciating pain, but I closed my eyes; I couldn't bear to look see how this ended.� I could still hear Jenna fighting to take in great lungfuls of air; still hear her body protesting as she was filled to such awful voluptuousness.

����������� And then it was over.� The sound of Jenna's breasts groaning faded, leaving only the sound of her still struggling to catch her breath.

�Ohh- I, I think it's finally stopped, I- I made it� came her dream-distant voice.

I ventured a glance, which being rewarded by the sight of Jenna sitting there alive and mostly unharmed, quickly grew into a stare.

�Oh my gosh, I can't believe I was able to hold all of it,� Jenna sighed, her voice still weak, her bosom still wobbling with the aftershocks of being so sublimely overfilled, �I hope it really is over; I feel like if I gained another inch right now my tits would just explode.�

����������� It was hard to argue with her; I had never imagined a woman so alluringly huge as Jenna had become, much less laid eyes on one, sitting there before me, naked and shivering as she smiled at me.� Her ass was so titanically fat that she sat as high upon it as she had when she first sat on the ball, her hips so winsomely full that her elbows sank several inches into their softness.� Indeed, her lower body billowed out at least a foot at her sides and behind her; had it not been for the rest of her figure, Jenna would have been the most enormously pear-shaped woman in the world, her overstuffed behind still quivering gently as she sat, as if her entire body had been pumped full of jello until she was about to burst, and then been pumped up with another barrelful just for good measure.� I couldn't even see her belly, tremendous though it surely had to be from the awkward angle her legs were splayed out at, and as I stood and saw from behind how it spilled out over her hips I could only guess at how exquisitely indulgent it had to be, weighed down by the weight of Jenna's bosom.

����������� It was strangely fitting.� Jenna's breasts were expanded to every bit as large as her ball had been, each fully two feet and a half across, though they looked so awfully heavy that if she ever was able to stand I expected they would hang considerably lower.� Their skin was stretched almost to translucence, the network of bluish veins that fed them now quite visible even in the light of early evening.� Though much of their weight was borne by Jenna's belly and thighs, they already bore signs of how it strained them to be so desperately overfilled.� White striations marred Jenna's smooth skin near where they blossomed from her chest, while below they had taken on a pinkish cast, though whether it was from slapping so forcefully against her legs or being compelled to carry such an onerous burden would only be known if it faded or grew more pronounced as Jenna grew used her new body.� Her nipples were so swollen I fancied that I could grab them like a farmer milking a cow, though from the way they stiffened and throbbed, I doubted Jenna was in any condition for such treatment right now.

�I- I never knew having tits to fat they were fit to burst would be such a turn-on,� Jenna murmured to herself, her hands exploring her overflowing curves, �Oh, I just can't wait for you to touch every last inch of me.�

�So you're feeling better then?� I asked, relieved that Jenna seemed to be taking this so well.

�Oh my- I don't even have the words,� she murmured, �I never even thought about what it would be like to feel the floor cold against the underside of my belly like it is right now, or to have an ass so fat that it feels like sitting on a couple of balloons crammed full of jelly.� Oh, I hope I can still walk after this; I bet just feeling my hips sway and wobble when I move will take my breath away.� And the pressure!� So much soft flesh bearing down against me, pressing inwards against my deepest places, my lips feel like they're just as swollen with fat as the rest of me; I'm just so tight, so wet and ready, I can hardly wait for you to help me discover all the places that will make me scream.�

�And your boobs, they don't hurt too much?� I asked, trying to keep my concern for Jenna from crumbling before my eagerness to make her wait a brief one.

�Oh no, I mean, every single nerve in my tits feels full of lightning right now; I think if you just pinched one of my nipples I might just boil over,� Jenna admitted, �But ohh, they feel incredible.� So much liquid sensuality, it's like balancing at the edge of a cliff; it's so exciting, feeling my body saturated with so much femininity that I can barely hold it all.� Even my nipples are so deliciously heavy; I can feel them weighing on my breasts, tugging them lower as if they're desperate for me to rub them against the floor, or maybe against you, if you're lucky and play nice with your fat, horny girlfriend.� It makes me wince just thinking of squeezing them, but I can't wait to feel them rolling and bulging under my body with you on top of me, making my fat ass bounce and jiggle so hard that if I were still on top of that ball my tits explode in an instant.

�Do you want to try getting up then?� I asked, still feeling as if it might not be quite decent to take advantage of the situation, no matter how nearly immobile and openly eager Jenna was, �Are you safe to move or do you want to stay there until you're feeling a bit more stable?�

�I think I left safe behind about three hundred pounds ago,� Jenna sighed, sounding anything but worried by her admission, �I can see just as well as you how awfully my poor tits are stretched from becoming so massively, wonderfully fat.� My arms are thicker than my waist used to be; I'm not sure I could even raise them over my head right now.� And look, I've got stretch marks all the way down from my sides to my hips; the only time I've ever seen worse ones is when one of my girlfriends got pregnant with triplets and by her third trimester her entire belly was so overstretched she looked like she'd swallowed a beach ball.� I'm just- I'm just so enormous; I don't even know where to start if I wanted to stand up.� I'm just so, so full, like it's all I can ask of my body is to just exist like this; being able to walk, being able to do anything is just right out the window, and all I can do is sit here and try to contain myself when I jiggle just a little too much and feel like I'm going to pass out.� Everything is just so sensitive now, so agonizingly tender; my tits, my ass, even my belly, I feel like I've been inflated with pleasure until I'm ready to pop.� I'm almost afraid to move just because I might bump into something with sharp corners.�

�Is it very uncomfortable?� I asked, anxiously watching the way that Jenna handled her body, as if she were fighting between the desire to discover just what sensations it could give her now, and fear that her limits pressed very near indeed.

�No- Well, not really,� Jenna admitted, still rubbing her bloated boobs tentatively, �I just sort of ache all over from too much, well, muchness, like there's a good reason why no woman has her tits blow up to the size of exercise balls, and I'm going to have to get used to living with the consequences.� I know they're going to be so sore in the morning; I've forced my body to gain more in an afternoon than it was meant to take in a lifetime.� I almost just want to crawl into bed and not get out until I can move without every inch of my body overwhelming my brain with all these new sensations.�

�Well, come on then,� I said, offering Jenna my hand, �now that you're not getting any bigger, we can take our time getting you into the bedroom.� Here, let me help you up.�

����������� It was slow going; Jenna was still just beginning to come to comprehend exactly how huge she had become.� When she tried to get on her knees, her ass was so enormous that she couldn't sit back on her haunches far enough to even kneel properly.� She tried to get on her hands and knees, but her belly was so lush that she couldn't crawl; her breasts so titanic that she could only touch her fingers to the ground when her bosom was bearing the entire weight of her body, spilling out in front of her and around her arms.� Even as we worked to get Jenna to her feet, her body quaked and wobbled unpredictably, so that moving just an inch this way or that would send a couple hundred pounds of quivering titflesh jiggling and rolling wildly.

����������� At last we succeeded, and Jenna stood, tired and precarious on her own two feet, not that she could see them.� With a saucy smile that belied all that she had just endured, she reached out her arms and pulled me in close, embracing me with the welcoming softness of her lush bosom.

�You feeling a little better then?� I asked, trying to figure out how to hug a woman who was probably at least eight feet around and finally just working my arms underneath her breasts, which only drew me deeper between them but left me squeezing her womanly hips, her warm, full belly pressing invitingly against me, �I know you're still freaking out about being this big, but I'm here for you and, well, this might sound weird, but I've never wanted you more.�

�Mmm, well, I am feeling a little better now that I've had a chance to catch my breath,� Jenna purred as she kissed me, giving her hips a little shimmy that sent waves through her indecently voluptuous figure, �And you don't have to tell me you like me this way; I can feel you prodding against my big, fat belly so hard I'm almost tempted to just move a couple of inches and find out how it feels to let you fuck me in between my fat rolls.� Actually, my bellybutton is probably deep enough for that now, if me being this huge really turns you on, how would you like to just spear me right in the middle of my soft, swollen tummy, and ride me while my whole body just quivers, my huge tits just slapping against your chest?�

�Are you sure?� I asked, finding the idea strangely arousing, though certain that any such treatment for make Jenna buckle at the knees at my first thrust, �Are you really up for that right now?�

�Ah, you're probably right,� Jenna admitted with a sly wink, as she drew her arms in tight and squeezed me seductively between her warm globes, �I have had an awfully full day, now haven't I?� I guess we could save that for tomorrow.� Maybe you should help me back to bed, and lie down yourself for a while; I'm sure it must have been very hard work helping your girlfriend up after she went and inflated her tits like a pair of zeppelins.� And you know, right now I'm still more turned on than I've ever been in my life, and I haven't even had you inside me since this started.� I don't think I'll be able to sleep until I find out how sex feels now that I'm so gloriously fucking huge.� So yeah, maybe you can just lay back and relax for a bit, since you're clearly ready for another round with me, and I can pull myself up onto the bed with you, bed-springs groaning, my monster titties hanging all warm and heavy in your face until they almost smother you, my nipples just throbbing, aching to be sucked.� I know you're already imagining feeling my belly, so huge and warm and womanly just spilling out over you as I settled in, my overstuffed ass pinning you to down as I heave myself into position.� I feel so insatiable now; I hardly know where my body even ends anymore, but I know exactly where I want you, so hot, and wet and swollen with desire, all my softest parts just soaked with lust, so ready to take you inside me, so full and tight that it's frightening.� I'll lower myself into position so slowly, oh, I can hardly control myself, and then, well- well, let's just say if you're willing, I think I could do with a little more bouncing before I'm ready to call it a night.�
