As Much as She Can Take

by: Kodos

“Well, someone got off early today,” Val said with a suggestive smile as I stepped into the old townhouse, “I know it's Colette's birthday and all today, but honestly, sometimes you two are like a couple of teenagers.”

“Hey now, don't be like that, Val,” I protested to my girlfriend's housemate, “I'd been planning on coming over this evening and taking her out for the full classy restaurant/champagne and romance treatment. About an hour ago though, Colette sent me a text saying she had a surprise for me and I needed to come right over as soon as I could get away.”

“Oh, a surprise, eh?” The leggy brunette arched an eyebrow knowingly as she looked up from inspecting the tires on her bike, “Well, if I know Colette, it's probably something kinky and weird, but who am I to judge just because I haven't so much as kissed a guy in six months?”

“You know something, don't you?” I countered. Val hardly ever talked about her Colette's unusual proclivities with me; something big had to be going on, “Come on, tell me what you know; I don't want to just walk into this blind if she's got something really freaky planned for me.”

“No, no, I've said to much already,” Val said with a conspiratorial wink as she loaded her camping gear into a large backpack, “I'd hate to ruin the surprise. I'm just glad I'm going to be spending all weekend out riding down along the river with some friends, so you two can be as loud as you want; as long as I haven't forgotten to pack anything, I probably won't even stop by again until Monday morning.”

“Oh, well, have a fun weekend then, Val,” I told her as she headed for the door, her Lycra bike shorts showing off her shapely rear.

“Ha, you have a fun one too, lover boy,” Val said with a crooked smile, “And stop staring at my ass. It isn't like you're not going to spend the weekend seeing plenty of Colette's.”

And with a slam of the door I found myself alone in the living room, with the faint sound of creaking floorboards above that told me my girlfriend awaited upstairs. With a certain mix of apprehension and excitement, I made my way up the steps and knocked on Colette's bedroom door.

“Come in,” she called cheerfully, “Have I got something that is going to just drive you wild!”

With one last twinge of trepidation, I opened the door, all sorts of possibilities flashing through my mind as to just what my girlfriend had waiting for me. As I stepped into the room though, I found that whatever romantic fantasies I might have entertained, reality, at first blush, was far more mundane.

“Hi there, love,” Colette said with a saucy smile, “Come to help me have a happy birthday?”

“You did say you had a surprise for me,” I answered, “And you know I can't resist your surprises.”

Colette sat before me on the bed, fully clothed, smiling like as if she had in her possession the juiciest secret in the history of juicy secrets. Her black hair was cut in a bob to that framed her round face, her gray eyes twinkling with mischief as she smiled at me, and then glanced down at a fair-sized parcel sitting on the bed in front of her.

“Go ahead then, open it up,” she said as she nodded towards the package expectantly.

As I gingerly picked it up, I had no idea exactly what I was about to unwrap. I had a pretty good idea though, as to what it was going to be used for, and I should probably explain a little bit more about Colette before I go any further here. Colette, you see, had an inflation fetish. When we first started seeing each other, I didn't know that was even a thing. It wasn't until we'd being going out for a month or so and found ourselves back at her place after a hitting a few bars that she pulled a couple of balloons from her nightstand, told me to blow them up until they were ready to pop, and then stuck them under her shirt. I have to admit, if it hadn't been for the fact that this had obviously gotten her ridiculously turned-on, I probably wouldn't have gone along with it, but seeing my girlfriend dancing around in her underwear, the seams of her top stretched tight as they could go, begging me to give it to her good and hard, well, let's just say it was a very memorable night for both of us, in the very best of ways.

The next morning, both of us sober and me wondering exactly what had happened, Colette told me her secret. Nothing turned her on as much as the idea of blowing herself up like a balloon. At the time it sounded completely weird, but she was still fun to hang out with, and even if she had a few quirks in the bedroom, well, that seemed to be working out okay for me so far. So that was what kept our love life interesting from then on. One time I brought her home an empty air tank from work and she put the hose in her mouth and pretended she was blowing up like a parade balloon. Once I came in to find her with a Pilate’s ball stuffed into her shirt as if she had an enormously round belly and she wanted me to take her from behind while she lay on top of it. Sometimes it was just her pretending she worked at a helium factory and there was a leak somewhere, and I'm sure it sounds really strange, but the fact is, when she was on top of me screaming, “Oh, my tits are getting so tight! You've got to keep fucking me or they're gonna burst!” I just couldn't help but get swept along too. Whenever I came by and found her waiting in bed with balloons or an air hose or anything that fed her obsession, I knew I was in for a hell of a night. So you can see that the moment Colette told me to open this box up, I could be pretty sure it wasn't lingerie or velvet handcuffs.

“Come on, don't just stand there staring like an idiot,” Colette said, “You wouldn't believe how much trouble I went to to get ahold of this.”

I opened the package. My suspicions had been spot on, for inside was an ordinary bicycle pump. It was a pretty high-end model, about two feet tall with a T handle at the top and a hose at the other end. Actually, I was pretty sure I'd seen Val toting around one of the same design with all her biking stuff. My curiosity was piqued as always when Colette offered up some new toy for her inflation games.

“A bike pump, hmm?” I asked with a smile, stepping into my usual role in these evenings, “And just who are we going to be blowing up with this?”

“Well, me, silly,” Colette said with a giggle, “You know how much I love it when you make me your big, sexy balloon girl.”

“So then,” I asked, turning the pump in my hands, “Where would you like me to start with this?”

“Actually, hon,” Colette said, drawing close to me and lowering her voice conspiratorially, “there's something I should tell you about this one. I know we usually pretend, and you've always been so good about playing along with my fantasies, but tonight we're doing this for real.”

“Really?” I asked, not sure whether to believe her or not. I was almost positive that this was just a new twist for tonight, an extra little bit of realism that would help her to enjoy herself that much more. Then again, there was just something in her voice, and in the playful seriousness of her eyes that made it hard to think she was just leading me on.

“Oh yes,” Colette purred, curling her lips into a lascivious smile, “As much as I've enjoyed playing pretend with you, I've been wanting to put away my childish toys for a while now and really get serious about this. It wasn't until last week though that I finally found a way to make me just as big as I've always imagined; maybe even bigger, if you're game for really taking me as far as I can go.”

“So, um, how does it work exactly?” I asked, torn between how utterly straight she was playing this and how completely unremarkable the pump appeared to be; “Do I just stick this end in your mouth and go to work?”

“Oh no, it's much more refined than that,” Colette explained knowingly, “Go ahead, why don't you read the directions?”

Sure enough, at the bottom of the box was a thin sheet of paper that looked like it had been done up on a manual typewriter. The brief directions read:

ATTENTION: PLEASE FOLLOW ALL INSTRUCTIONS WHEN USING THIS DEVICE. FAILURE TO DO SO CAN RESULT IN UNINTENDED AND/OR PERMANENT INFLATION.

This pump has been factory-adjusted for its intended user. Do not try to alter the factory settings.

When in use, do not remove pump more than 100 feet from user.

Do not employ this device as an actual air pump. This equipment has been altered to operate without use of the hose.

When using pump, be sure to push handle down completely on every cycle.

Stop use immediately if inflation to excessive size occurs or user experiences dizziness, shortness of breath, or overwhelming euphoria.

“So, where did you get this thing, anyway?” I asked Colette, who was looking on at the pump as if it was the greatest thing in the world, “I mean, I don't want to burst you bubble or anything, but it looks pretty normal to me.”

“Oh, don't worry about that, love,” Colette said perkily, “I actually found a woman on the internet who builds them. She didn't say much about herself or how she discovered all this, or even how it works, come to think of it, just that there's something about that little shiny metal bit there right where the hose screws in that somehow redirects all the air pumped through it directly into me! And not like it's going to blow me up into a big, round ball with just my hands and feet sticking out; if what the girls who wrote those testimonials online say is true, it's all going straight to my more sensitive bits and I am going to end up with a figure that would turn the Venus of Willendorf green with envy.”

Colette was right; there was an odd-looking metal fitting attached to the base of the pump right where the hose came out. As far as I could see it was just a shiny, strangely-machined bit of metal, about three inches across, with nothing to suggest that it had the remarkable capabilities that my girlfriend seemed to believe it had. I still couldn't tell if she was playing at this or really believed that this thing was going to really work. Either way, it had been a long week, and I couldn't think of a better way to spend Friday night than driving Colette to distraction in all her favorite freaking ways.

“Well then,” she said with a mischievous smile, “Why don't we get down to business? Oh, I almost forgot! I expect you'll enjoy the show so much more if here's a bit more of me to be seen.”

And with that, Colette pulled her shirt off over her head, leaving her standing before me, stripped to the waist. Her breasts weren't exactly tiny, a pair of plump C-cups that hung a little bit on the low side when she took off her bra. All the same, they were each enough for a decent handful, and I'd always been satisfied with them. Colette, however, didn't exactly love her body; aside from being on the shorter end of average, her figure tended towards the pearish side, even though she wasn't really carrying much extra weight, she wore her sweatpants high to cover the gentle feminine bulge of her hips. However she felt about herself, I'd always appreciated Colette's shape, the way her hips gave me something to hold onto, and the way her butt kind of stuck out whenever she wore a skirt, not that she ever believed me when I told her how good I thought she looked, but then I've never dated a woman who actually liked her own body.

Something different was going on here already. Every time we'd played Colette's balloon games before this, she had always worn a baggy shirt, the better to hold whatever she was stuffing under it, and it certainly added to the illusion if I couldn't see her clutching a couple of brightly rubber exercise balls to her chest. This whole going topless thing though- I shook my head in disbelief; maybe she really did expect to blow up this time around. There was only one way to find out. I set the pump on the bedroom floor, pulled up the handle and looked up at Colette.

“Okay, you're sure you're ready for this?” I asked her.

“Oh, I've been ready for this for years,” Colette grinned, “Push it!”

I pressed down, the handle resisting ever so slightly; Colette gasped and staggered back against the bed.

“What's wrong?” I asked, worried that I had somehow hurt her, “Are you okay?”

“Oh, oh yes, I'm fine,” she assured me, holding a hand to her chest as she fought to catch her breath, “Sorry, I just didn't expect it to feel so good. Do it again.”

I pulled up the handle and pushed it in again.

“Mmm, ahhh,” Colette breathed, able to keep her feet this time; while the expression she wore suggested that whatever was really happening here, it was extremely stimulating for her, “I'm fine, come on, keep going.”

Even if she wasn't getting any bigger, this was definitely doing something for her, so I gave the pump another push, and then another couple more for good measure. Colette gasped, grabbing at her chest with both hands and leaning against her bed for support.

“Oh, my- it's really working, I'm getting bigger,” she announced delightedly, cupping her breasts firmly.

I knew this was the part where I was supposed to play along, to agree with breathless enthusiasm that her modest mounds were in fact being blown up through my efforts. The words I had been planning to say died on my lips though, for when Colette's hands slipped away from her bosom, I saw she was right, her breasts were noticeably larger. Nothing too dramatic; she probably hadn't even gone up a full cup size yet, but all the same, her breasts, the shapes of which I was intimately familiar with, had become visibly fuller, and larger.

“Whoa, you really are getting bigger,” I said dumbly as the truth struck me, “How does it feel?”

“Incredible,” Colette said softly, “I can feel it tickling me from the inside. I've waited so long for this; please, don't stop.”

Surprised to find that my efforts were actually having an effect on Colette's figure, I complied, steadily pumping away as I watched the results intently. Each push elicited another stifled sigh of pleasure, her breasts plumping up unmistakably every time the handle of the pump clinked against its base. It was hypnotic to behold; Colette's breasts really were inflating this time. If anything, they seemed to ride higher than before, gravity's slight effects disappearing as they grew fuller and rounder, now clearly at least a D cup, and expanding willingly as I pumped more air into her.

“Come on, don't stop to stare at them,” Colette chided me as I paused to admire her increasingly ample bosom; “You can ogle my tits all you want while you're them up like a couple of helium balloons.”

Chastened, I returned to my work, still amazed at what I saw. Colette's breasts continued to fill up, gently ballooning larger and larger with every push of the handle. Drunk with the bliss of her expanding endowments, she seemed to hardly remember I was there, murmuring softly to herself as she dreamily fondled her growing breasts. I watched intently as they swelled ever larger, Colette's two soft little hills inflating well beyond buxom and into the range where people assume a girl is either a stripper who has had some serious work done, or else has some kind of major hormonal imbalance. Much too large for her small hands to grasp now, Colette's breasts were inching out wider than her body.

Colette's breasts changed subtly in shape as I inflated them with more air, the growing volume they were forced to hold bloating them into a pair of fat, pneumatic torpedoes. Even as huge as they had become, Colette's breasts still rested, ever so gently against her chest, the upper part of her stomach thoroughly hidden in their shadow. Her nipples, which had always pointed a bit downwards, now poked proudly out in front of her, and while they had perked up as soon as I started, I saw that they were expanding visibly as well; her two little eraser-sized nubs had fattened up to twice their size, and I could see them quivering faintly as I filled Colette with more. Emerging for a moment from her reverie of self-indulgence, she flashed me a coquettish smile, hefting her swollen assets as if they might otherwise go unnoticed.

“So, what do you think of my girls now?” Colette asked, swaying her hips enticingly as she leaned forward, “All those months of playing pretend with my tiny little tits, and now I've got these beauties for us to have some fun with!”

“How do they feel now?” I asked, curious as to just what it felt like for Colette to have her lifelong fantasy finally come true.

“Oh my gosh, I can't even describe it,” Colette sighed as she squeezed her enticingly enlarged breasts lustfully, “I can feel the pressure building inside of me, filling my boobs up bigger and bigger with every pump. The way they're stretching to hold it all- I don't even know, it just makes every inch of my skin feel so sensitive, so- so alive.”

“Do you mind if I have a feel?” I asked, hardly able to resist the sight of my girlfriend so fervently enjoying her ample bosom.

“Oh, yes, come over here and give them a real-” Colette managed breathlessly, her eyes gleaming with desire for a moment before a coy look stole across her face, “Actually, lover, not that I can't wait for you to get ahold of me, but don't you think it would be even better if you inflated a bit bigger before we really get down to business. I mean, even if we start out with the best of intentions, once we get into bed with these neither of us is going to be coming up for air for a while, and as amazing as it is having boobs like a Saturday night stripper, just think how incredible it'll be if you blow me up until I'm as big as I've always wanted to be. Do you remember that night I stuffed a couple of beach balls under my shirt and we didn't even get out of bed until lunchtime the next day? That's what I want. Give that to me and I'll give you things you never even dreamed of!”

How could I say no when she put it that way? I could hardly wait to get ahold of Colette, to feel those huge, swollen tits of hers pressed tightly between our bodies, but then again, an offer like she was making, wasn't that worth waiting for? I struggled to imagine her with boobs that huge. Colette was already by far the bustiest girl I'd ever seen in real life, and I found I was having a hard time guessing just what she'd look like with her breasts inflated to several times larger. If they got that big, were they going to rise up in front of her face like a couple helium balloons or stick straight out from her chest, her chubby little belly hidden beneath them? I smiled back at her; there was only one way to find out.

“Yes, ma'am,” I said dutifully, and got to work.

Colette's eyes and mine were fixed to her breasts as I steadily pumped away. Each push of the handle left them more bloated, her two softly hanging melons becoming fuller and rounder as I worked. Before long they were several inches wider than Colette's shoulders, and she had taken to squeezing them as tightly together as she could stand, then letting go and giggling with a delight that was only partly erotic as her swelling breasts popped back apart, each one thirsty for room to expand.

“Oh yesss,” Colette exhaled through clenched teeth, rubbing her buoyant assets insistently, “It just feels so good. I never thought they'd be so- so responsive. Oh, I think I might have spoken too soon when I said I wanted them as big as beach balls.”

“What, feeling too full already?” I asked, surprised at her sudden change of heart.

“Not in the least,” Colette said with a libidinous smile, “I was just thinking I might want to shoot for something more like the size of that Pilates ball I had so much fun with back during spring break. You think you can handle that much me?”

“I can handle as much of you as you want to give me,” I assured Colette, her eyes twinkling lustfully at my words, “But just how much more air do you think you can handle?”

“Oh, this, this is just the start,” she said breathlessly, “I think I could take a hundred times what you've already given me before I started feeling a little overextended. Though I have to admit, and I know it's a bad idea, I just can't resist the thought of testing my limits and having you just pump me up until I'm so overfilled I have to beg you to stop.”

“I think I could get behind that idea,” I said, and set to pumping her up at a faster pace.

“Ahhh,” Colette gasped as she felt the air rushing inside of her. Her breasts began to expand much more rapidly now. Though they still rested lightly against her body, they were growing increasingly round, their shape now barely suggesting that gravity held any sway over them. Each nearly a foot across, Colette's growing boobs jutted out proudly in front of her, pressing against her arms as she cradled them in her hands, which looked far too small to support such spectacular spheres so effortlessly. As she turned for a moment I nearly choked at the sight of her profile. I understood now why she had wanted this for so long, the fascination that had brought her to this point; Colette had become the very image of female sexuality come to life, her bustline blown up to such stunning proportions.

As she moaned in delight, I pumped faster and faster; I couldn't wait to bring her fantasy to hot and vivid life, to inflate her with as much as she could possibly stand. All my concerns about whether this was actually a good idea had melted away; I worked feverishly, watching raptly as Colette happily explored her expanding bosom. After a few minutes, I realized that the pump was getting harder to work. The handle now resisted slightly as I pushed down on it, and looking back up at Colette, I noticed she was staring at me quizzically.

“What's wrong, hon?” I asked.

“Um, I think it's stopped working or something,” she said, her huge breasts trembling gently as she leaned forward to look at the pump, her nose crinkling up ever so slightly as she tried to figure out what the problem was, “Actually, I think it's been a couple minutes since I got any bigger; I guess I was just so wrapped up in how good my tits felt that I didn't even notice there wasn't any air flowing into them anymore.”

“That's no good, you don't think it's broken, do you?” I asked, worried now that my visions of Colette with a pair of melons so enormous that she could barely walk were going to come to naught.

“I don't think so,” she said thoughtfully, walking over and kneeling down by the pump, her breasts swaying pneumatically as she moved with winsome awkwardness, “You know, until now I never knew how much harder it is to walk when you can't see your feet. Anyways, are you sure you're doing it right?”

“There isn't that much to do wrong, is there?” I replied, “I mean, you push down on the thing and buying a bra that actually fits those behemoths gets just a little harder for you; it's not that complicated.”

“Wait, what did the instructions say?” Colette asked suddenly, “Don't you have to press it all the way down for it to work?”

“Oh, right, I'll bet that is it,” I said, “Here, tell me if you feel this-”

I gave the handle a firm push; it clinked against the base of the pump, and Colette suddenly tripped fell backwards onto the floor, emitting a startled shriek. There was a sort of a muffled “Bloomp!” mingled with the sound of skin slapping against skin and some rather alarming stretching sounds. It took me a second to realize just what had happened; Colette had just doubled in size.

Her breasts were now bloated to the point where if they were beach balls, they were ones which had been overinflated to about twice their recommended capacity. Quivering with fullness, they seemed to jiggle weightlessly in time with Colette's breathing, her areolae each now stretched to several inches across, and her nipples engorged like a couple of ripe cherry tomatoes. As round as they were, Colette's breasts still remained tantalizingly soft, their skin giving readily to her touch as she sighed with satisfaction and caressed her ever more ample dimensions.

“Oh, that was such a rush!” Colette murmured as she rose to her feet, clearly struggling to do so without being unnecessarily rough on her inflated globes, “Did you do that on purpose? I mean, I thought it felt good just blowing up bit by bit, but getting it all at once like that- Oh, if I was sure I could take it that much pleasure right now I'd make you do it again.”

“So, you're alright?” I asked, trying to look her in the eye with concern, but finding it impossible to lift my gaze to anything resembling eye-level.

“Alright? I never imagined I could feel so good,” Colette enthused. “Everything just feels so- so intoxicating, like I'm drunk on my own body! Oh, and did you notice I'm starting to expand all over now?”

As she gestured downwards invitingly, I saw what she was talking about. Though it was still somewhat obscured by her flourishing breasts, Colette's belly had been filled to the point where she had the shape of a woman six months pregnant. Her sweatpants looked barely able to contain her expanded figure now, pulled out tight in front to accommodate the added girth of her smooth, round belly. Her hips had endured the same treatment as well, Colette's once-slight muffin top now bulging insistently out over her waistband. Her thighs had grown much more generous as well, and as Colette did a turn to show off her more fulsome physique, I noticed that her butt had taken a fair bit of air as well, her rump bouncing and jiggling from the slightest movement, a quality that Colette proudly showed off by giving herself a solid smack on her behind.

“Well, don't just stand there staring, hon,” Colette said with feigned exasperation, her small hands planted firmly on her flaring hips, “Come over here and have a feel.”

She didn't have to tell me twice. Colette's breasts bulged up between us as we met; they felt even larger somehow when I actually had to reach around them to get to her. I was amazed at how, well, normal they felt. I had halfway expected her skin to feel like rubber or be drawn out super tight or something like that, but everything about her felt just as soft and natural as ever, just enlarged to a positively incredible degree. She drew me in close, her billowsome breasts bulging out to her sides, and I felt the softness of her swollen belly pressed invitingly against me. Closing the distance at last, she gave me a long, passionate kiss, pushing herself tightly against me as my hands explored all her lush and supple curves. This was so much hotter than I had ever imagined, and I reached for the waistband of Colette's sweatpants, lost in all the indescribable possibilities awaiting us.

“Mmm, not so fast now lover,” Colette said as she stepped back teasingly and sat down on the bed, her ass bulging outwards from her weight and her breasts hanging just a couple of inches above her welcoming lap, “So can I assume you're pleased with your hot new inflated girlfriend?”

“Are you kidding?” I asked, still drinking in the she sheer sensuality of her new shape, “I have never wanted you more than I do right now.”

“It makes me so happy to hear you say that,” Colette smiled, absent-mindedly playing with one of her nipples, which were barely within her reach, a small shiver coursing through her body every time she gave it a light pinch, “But as much as I'd like to hop in bed right this second, I just get shake the thought of how mind-blowing sex is going to be if you fill me up with just a bit more first.”

“And just how much more is 'just a bit,'” I asked, knowing that now that Colette had whetted her appetite for this, she wasn't going to be satisfied until she was absolutely filled to the brim.

“Okay, maybe not just a little bit,” she admitted with a guilty grin, “but it's not like I want to be so huge I can't even squeeze through the door or anything; we've got the whole weekend for that. I'd just like it if, you know, we kept going until the rest of me is every bit as impressive as my boobs are now. Can you imagine me with my belly swollen out past my knees? Or if my ass blown up wider than my bed? And don't try to tell me you wouldn't love feeling my thighs wrapped around you once you'd filled them up a little more, say maybe five or ten times their normal size. I mean, I've always been a little plump and bottom-heavy; I just want to take that to ridiculous extremes and give you plenty to hang onto when we're going at it. Is that so wrong?”

What could I say? I took up the pump again and set back to work. Colette was expanding faster now, I noticed. Where before every pump had seemed fill her up almost imperceptibly, now I could see her entire body shuddering faintly as I pushed. I could even hear the air hissing into her with every pump as before my eyes she began to resemble an obscenely overinflated blowup doll. Straining against her sweatpants as it grew, her belly began to bulge out above and below their waistband. Colette's hips, now that they had begun to expand as well, fairly billowed outwards, becoming broader and broader until even with her big, bloated belly she had a respectable hourglass figure. Her butt, where she had always tended to carry her extra weight anyways, was primed to receive even more, inflating eagerly beneath her, her rapidly expanding rear lifting her higher and higher above the bed until Colette looked as if she were having trouble keeping her balance on top of it. Her thighs ballooned as I forced more air inside her plaint figure, and as they swelled to ever more ravishing voluptuousness, I saw that she was having to spread them further and further apart as the lower curves of her belly became more and more sensually distended. Her breasts too continued to grow, though not nearly as quickly as her lower body, as if they had already been filled to their limits, leaving the rest of Colette's figure to contain all the air pumping into her. As the undersides of her immense boobs made contact with her thighs she bit at her lip and stifled a small cry, struggling to withstand the pleasure that was flowing into her like a river that had burst its banks.

“Oh yesss! Please, give me more,” she sighed weakly, “Come on, blow me up until I'm ready to burst!”

As she grew more and more inflated, Colette's legs soon swelled until her pants could barely hold them. Stitches straining to contain her lushness from thigh to ankle, she had become so very full and round that the fabric clung to her like a second skin, and I could see that her sublimely expanded figure was causing her more than a little discomfort. Colette was having trouble keeping her feet on the floor now, not only because her fattening legs were becoming reluctant to bend at the knees, but because the very size of her titanic ass was making her seat higher and more unstable by the second. Struggling to stay upright on the bed, Colette perched uncertainly on a rump nearly two and a half feet across.

“Please, I need more! It feels so good!” Colette begged, fighting to catch her breath, “You've got to keep going; don’t stop until I can't take it anymore!”

I was starting to worry about just how far it was safe to go with this. Colette already looked like she had taken more than she could handle, each of her breasts now swollen to two feet across, her areolae puffing out as if her body was barely able to hold so much air. Still, Colette was begging me. She wanted this so badly; she was overflowing with a kind of pleasure most women never experience, and I just couldn't bear to take that away from her just because I was losing my nerve. Besides, I figured, if she really was in danger, she'd be the first to know. If she felt herself getting too full, stretching too far to take all air I was pumping into her, surely she'd tell me to stop. And I did have to admit, blowing her up like this was pretty damn hot. Not just the fact that my girlfriend now had a shape like some kind of spectacularly overfattened fertility goddess, but the way she screamed like a like a runaway train- how could I resist giving her more?. I had to admit it; I was addicted to this too now. I tried to imagine what Colette would look like if I kept this up. How long would it take until her boobs were wider than the bed? How would she even walk with a belly so immense that reaching her arms around it was completely impossible? Just how much more could she take, and how much more did she want? And which of those things was she going to run into first?

“Don't torture me like this, keep pumping!” she cried beseechingly, grabbing and squeezing her inflated figure feverishly, as if every inch of her body was made of pure, intoxicating bliss, “Stop fucking around and blow me up like you mean it!”

Well, orders are orders. I found my rhythm, Colette sighing with relief as she began to expand again. As much as she was enjoying this, I knew that this couldn't go on forever. Her belly and hips were spilling out over the top of her pants obscenely now, giving her the mother of all muffin tops, her pants stretched as far as they could go, the air flowing into her still needing somewhere to go. Her bottom half now constrained, her breasts began to inflate at an alarming rate. With every pump they throbbed faintly, stretching meekly as I forced them to take in more and more. They each gained six inches in a matter of minutes, two vast pale spheres that even managed to hide Colette's quaking belly beneath their vastness. They swelled out just beyond her knees now, so spectacularly overfilled that I found myself wincing as Colette gave one of them a savage squeeze. Her boobs were inflated to such a size now that I couldn't help but worry that they needed to be treated with the greatest tenderness, just to be safe, but the sight of her treating them so roughly made me want her that much more.

“Dammit, stop staring at my tits and blow me up!” Colette screamed, “The sooner I burst out of these pants, the sooner you're going to get the best sex of your life, so come on, jump to it!”

I pumped faster, and Colette's breasts billowed out at a nigh-explosive rate. Her areolae stretched and stretched as the volume of air inside her boobs increased distressingly, their two rosy circles now drawn out wider than saucers, while her nipples with a loud pop, doubled again in size, their strawberry skin trembling as the pressure behind them mounted. The waistband of her pants looked like it was about to cut her in half, her impossibly inflated figure swelling out above and below it alarmingly. If it bothered her in the least, Colette gave no sign, her earlier cries of unrestrained pleasure having given way to a faint murmur of sheer ecstasy as she explored her burgeoning curves. Her breasts looked dangerously overinflated now, each one fully three feet across, even wider than the bed. They billowed out more than a foot beyond her knees, and even with the added height that her oversized ass gave her, they just barely touched the bed. Filled to the brim, Colette's breasts stuck out in from of her like a shelf, so very sensual, and yet so tantalizingly overfilled that I found my pace slowing down, as if the next push of the handle might be too much for her.

“Okay, I'll make this easy for you,” Colette said, rolling her eyes as she looked at me impatiently, “I can't fuck you until these pants are in tatters, and I don't want you to go gentle on me here.”

“I know,” I said sheepishly, “I just, I mean, it looks like it's all going into your boobs now and well, they're just starting to look kind of, um, full.”

“What, you don't think my fat, swollen tits are too big already do you?” Colette challenged, her massive bosom quivering as she thrust it out for my inspection, “I thought you wanted me to be your big, overinflated fuck toy, didn't you? Don't tell me that you're intimidated by the sight of a girl with knockers the size of beanbag chairs?”

“What? No, I- I mean, don't get me wrong, I think they-you look amazing,” I stammered, “It's just, well, they're looking a little, um, too overstretched, you know? Like maybe, from kind of a safety point of view, you've already got a lot more inside you than might really be a good idea.”

“Ohh, that,” Colette said knowingly, stroking one of her titanic melons affectionately, “I promise you, the twins here have never felt better. I mean it; you could probably fill them up with twice as much before I even started to think that maybe I was pushing my luck just a little. But alright, I can see you're just worried about me; and that's one of the things I love about you, hon. So how about this: you know that thing where you kind of half pumped me up and then pushed the handle down before? Trying giving me another one of those, maybe another twenty five pumps before- actually, let's make it fifty for good measure.”

“Are you sure you can take that much?” I asked, admiringly and incredulously.

“Oh, I could take so much more than that,” Colette smiled, “But I hate to see you worry, and I know I've been a bit demanding tonight, so yes, I think fifty should do quite nicely, thank you.”

“Alright, as long as that's what you want,” I said reluctantly.

I pushed the handle down again, stopping just shy of all the way. Five, ten, fifteen; as I counted off in my head, Colette smiled at me seductively, twisting her hair around her finger lazily and trying, without much success, to cross her swollen legs demurely. Twenty, twenty five, thirty; I tried to think about how much of a charge I was building up here. Fifty pumps was a lot; I tried to figure out just how much bigger that was going to make her. I couldn't take my eyes off her breasts, and not just because they were insanely sexy; I just couldn't believe that those enormously distended jugs of hers could take as much air as she wanted them to, especially if it all came into her in the blink of an eye.

“Hey now, that one was hardly halfway down,” Colette admonished me, “I'm trying to be reasonable here, but you've got to give a girl what she needs. Come on now, make it seventy five, then, and if every one of them isn't just barely over the top, I'll make it a hundred, you know I will.”

Silently, nervously, I continued my efforts, afraid to look like I was skimping, but just as worried about what might happen if I pushed just a little too far. Still I counted to myself, desperate not to add a single stroke more than seventy five, and knowing that if Colette thought I'd come up short she'd probably make the total two hundred or some other wildly thoughtless number, a thought that both frightened and excited me. Finally I had it, seventy five, the handle of the pump just barely above the ring that connected it to the body.

“Don't keep a girl waiting; give it to me” Colette breathed lustfully, “Just push it in one more inch and I'll be so much woman you'll think you've died and gone to heaven once I show you what a girl with a pneumatic figure can really do for a man. I'm begging you, make me so much more than I already am, and I'll make it worth your while in ways that will make you deliriously happy.”

I had to obey. I pushed the handle down with all the serenity of a man pushing the plunger on a nearby barrel of dynamite. Colette screamed as her breasts surged outwards another six inches, filled to the very limits of their elasticity and still expanding as the built-up air flooded into them. Her jaw clenched tightly, Colette wore an expression that could have been agony or unbearable pleasure. There was a tearing sound, quickly growing louder, and loud pop that knocked her back onto the bed. Colette's sweatpants, stretched far beyond their limits, had split apart, releasing her colossal belly from its confinement. As the pressure in her body spread out more evenly, Colette's massively overfilled breasts deflated rapidly, the volume that had stretched them to the brink of bursting rushing to fill less overloaded regions of her anatomy.

Colette's belly, no longer banded tightly about the middle, swiftly ballooned out in front of her. Already she looked breathtakingly pregnant, her green panties retreating downwards below the irresistible curve of her belly. The rest came in quickly, her belly growing spectacularly enlarged as I looked on. Thrown back by the shock, Colette lay back on the bed before me, and seeing her once-pudgy middle blow up like this from below was a mesmerizing sight. I heard the muffled whoosh of air inside of her, as her belly inflated to nearly three feet wide. Before long it bulged out so far above her body that it began to obscure even Colette's huge breasts, and even with her laying supine on the bed, it was so immense that its lower hemisphere was forcing her legs farther and farther apart. Her belly expanded wider than her body, then wider than her hips; with a soft pop, her belly button became strikingly convex. As her growth began to slow, I realized the air was still rushing through her body. Colette's ass, which I was in excellent position to view, all but exploded beneath her, bloating up until she was fully half as wide as the bed. It was filled until it was tough to tell exactly where her billowing behind left off and her lush thighs began. Even her calves were pumped up to super-feminine fullness, Colette's legs now so thick that it looked like she would hardly be able to bend them.

Colette's transformation slowing, the hissing faded into silence, and she lay the unmoving on the bed, her entire body faintly trembling with excess. Worried that this had finally been too much for her, I dropped the pump and carefully, tenderly, patted her on her bountiful belly. Again I was surprised: for all the air that had been pumped into her body, Colette's skin still felt warm and inviting to the touch, supple and soft as I dared to push my fingers a little more firmly against her swollen middle.

“Ohhh, hmm,” Colette sighed as she swam back to consciousness, “Oh, did I faint?”

“Sure seems like it,” I said, relieved to hear her voice, “Are you alright?”

“Oh my gosh, I didn't know what feeling good felt like until just now,” Colette replied hazily, her hands dazedly wandering across the acres of smooth flesh now lain bare, “You weren't worried, were you, love? Okay, my ass is so gigantic now that laying down is making my back hurt; give me a hand getting up, would you?”

I took her offered hand and helped pull Colette to her feet. It was a surreal experience, picking up a woman who took up the greater portion of a king-sized bed as easily as if she was still a size fourteen. Her inflated physique pressed against me in all sorts of stimulating ways as I leaned in to help her, and Colette's undisguised murmurs of desire told me everything I needed to know about her current condition. As she sat up, her belly creaked distressingly, squeezed between her winsomely enlarged thighs and her gently wobbling breasts. As she stood and straightened up in front of me though, I had to take a step back. Not just because Colette had been filled to such an extent that I was almost afraid to touch her, but because I could see now that our efforts had transformed her into a veritable goddess.

Apparently being distended to more than three feet across and then deflated by a considerable degree had left a lasting mark on her breasts. They were not nearly as spherical as before, and having been so savagely overstretched left them looking like two lusciously bloated pink zeppelins. Each one was still more than two feet across at the widest, and hung a little lower, but I actually kind of preferred this to the party balloon shape they'd had a just minutes before. With Colette's fat nipples now pointing slightly downwards again, her boobs had a soft, heavy kind of fullness to them. It didn't hurt that they hung more closely together now as well, giving Colette a long, inviting cleft of cleavage from her collarbone to where her voluptuously full belly divided her swollen melons. Her ungainly belly swelled out fully three feet in front of her body, and was every inch as wide. Provocatively round, Colette's belly still reached more than halfway to her knees, swaying winsomely as she patted it appreciatively. Her massive hips swelled out as broad as her bust, their flawlessly smooth abundance just begging for a lover's questing hands.

“So, what do you think?” Colette asked with a come-hither look, her entire body quivering in slow motion, as if she were underwater, “Aren't you glad you went ahead and gave me what I wanted? Come on, have a feel; I didn't do all this so you could stand there like you were afraid to touch me, so overinflated and horny I feel like I'm about to pop.”

Colette stepped forwards again, pushing me back against the well. As she leaned forward, her sumptuous figure surrounded me. Her titanic breasts pressed with compliant insistence against my chest, swelling and subsiding slightly with Colette's every breath. Her massive belly pinned me where I stood. My hands hidden in the awesome abundance of Colette's charms, I gave her mammoth bosom a tentative squeeze, savoring how submissively her swollen breasts behaved, quaking weightlessly as I hefted them. I rubbed my palms along the smooth sides of Colette's vast belly, until its graceful curve gave way to the blossoming fullness of her hips. She was far too inflated for me to reach all the way around her waist; I actually would have been impressed if I even made it halfway, but still I squeezed her tightly, just barely able to give her jigglesome ass an appreciative squeeze.

“Mmm, I can tell you're ready for some action,” Colette purred, rubbing herself against me more ardently, “but you see there's still one thing keeping you from just throwing me down on that bed and fucking me until I beg for mercy.”

“What's that?” I asked, eager to get my oversexed and overinflated girlfriend into bed, but still curious at what new kink she was about to throw in.

“Why it's right down here,” Colette said, gently guiding my hand across the lower regions of her belly, “Yes, that's it, a little lower though, and further in, like this.”

Slowly and seductively Colette drew my hand across the silky skin of her belly, lower and lower. I found my arms weren't long enough to go where she was leading me; I had to bend my knees and lean forwards, Colette giggling devilishly as she pushed my head between her bloated tits. Colette drew my hand inwards, tracing my fingers back and forth along the smooth underside of her belly. Her body quaked softly as she giggled at my situation, face buried in her sumptuously ample cleavage, my arm drawn deeply beneath her overhanging belly. It seemed to stick out far beyond what I had imagined, and as I found myself pressed deeper and deeper against Colette's very full bosom, I knew exactly where she was leading me. I had finally reached the end of her round belly, the tight, thin fabric against my fingers doing nothing to disguise the supple contours of her swollen womanhood beneath, wetly throbbing with overfullness and barely-contained desire. Colette released my hand.

“You see, you can't have me yet because, strictly speaking, I'm not quite naked,” she said, savoring the rules of her game, “If you really want me, and I sooo hope that you do, you're going to have to get me out of these first.”

“I don't suppose I could just pull them off,” I suggested helpfully, reaching for where I expected the waistband of her panties must be, “They feel so tight I bet it would be easy to just tear them off.”

“Oh, you have no idea how tight they feel,” Colette said throatily, swatting my hand away from her straining underthings, “they're so tight they're pinching me in all sorts of unmentionable ways; it's making me so wet just thinking about what we're going to do once I'm finally out of them. Still, that's not how this game is played. If you want to have your way with me, to finally have the pleasure of taking your helplessly inflated girlfriend to the moon and back, you're going to have to get me naked my way: pick up that pump and don't stop until every inch of me is exposed and waiting for your touch.”

“Are you sure? I mean, if we just did it now, it's not like I'd be disappointed with you, you're already so, so-” I tried to explain, partly because I could barely wait to have the unutterably voluptuous woman who stood before me and partly because I was really worried about what might happen to Colette if she forced her overinflated body to hold much more, “I mean, I can always pump you up more tomorrow, if you still want it then.”

“I'd never forgive you if you didn't,” Colette smiled, her words dripping with anticipation, “But if you make me bigger tonight, then you can blow me up even more tomorrow. So there it is; if you want to delight in my embrace tonight, you'll push me just a little further.”

A dozen arguments against this sprung to mind, but I was helpless. The thought of pumping Colette up with even more was just too irresistible. I had thought that the larger she became, the easier it would be to put my foot down, but as it turned out, I was just as hooked as she was. Even if it was just a couple more pumps, I had to see what was going to happen if I made her bigger. As Colette leaned languidly against the bed, I started pumping again. It was nothing short of awe-inspiring watching her expand as I pushed in the handle. With nothing but a pair of overstretched panties to contain her, and standing proudly before me I could see how every pump inflated her pliant form with that much more. Each time I pushed it down all the way, she shuddered weakly, and I could hear the air rushing quietly and inexorably into her. I watched raptly as her breasts were filled with more and more, still not nearly as bloated as they had been at their most bloated, but sublimely ravishing all the same. Her belly became wider and rounder as she grew, its swollen sides bulging out farther and farther, her fondlesome thighs gradually disappearing as it expanded lower, steadily advancing on her knees even as it bulged out in front of her to the point that I wondered how she would even be able to walk around if this turned out to be permanent. Colette moaned softly with each push; the tightness of her straining panties exciting her terribly. I pumped harder; she fought for breath, her gigantic ass billowing out onto the bed behind her, her indulgent thighs pushing the rest of her away from the bed. She surrendered to the pleasure of it shamelessly, each pump giving more intensity to the orgasm building inside her exquisitely enlarged figure. I heard her body creaking faintly as I inflated her with more, and between her labored gasps of anguished bliss I could discern the faint fraying noises of fabric being stretched beyond its limits. A few more pumps, Colette's breasts were fully two and a half feet wide again, though still resting tenderly atop a belly inflated to radiant immensity She screamed as the climax took her, her sensually overfilled body quivering helplessly as she came, and in the midst of it all, there was a muffled pop.

Slowly, Colette regained herself. Eyes brimming with desire, she looked up at me and smiled. Wordlessly, she struggled to slide her hand beneath her enormous belly, and smiling with lasciviousness, she drew out a pair of pale green panties, soaked with desire and torn to shreds. She tossed them aside dismissively and fixed me with a look of raw, untamed lust.

“Okay lover,” she said huskily as she climbed awkwardly onto the bed, the slightest motion setting her body aquiver with excess, “You've more than paid for your ticket, why don't you come have a ride?”

Colette wasted no time waiting for an answer, but pulled herself the rest of the way onto the bed. Her luscious form jiggled hypnotically as she moved with a sort of weightless ponderousness, gravity barely teasing at her inflated endowments. Soon she was in position; the underside of her massive belly swelling out towards me, her mammoth breasts laying gently on top of it.

“Well, I'm in no condition to sit up,” Colette called out to me, “Why don't you just come on up on top here? You know how I like it.”

This was it. In a moment I was out of my clothes. I had meant to be gentle with Colette, worried about how safe it was for me to climb on top of her, excessively inflated as she was. The very feel of her supple skin against mine though, scoured such all concerns from my mind. Colette sighed with pleasure as I positioned myself on top of her; usually I tried to support myself on the bed when we were together, but now that she was enlarged to such prodigious dimensions there was no other choice but to lie upon her. With my weight as well as her own weighing against her, Colette's huge behind bulged out even wider. As I tried to get into position, her belly yielded beneath me, its vast roundness surrendering to let me closer. The sides of her belly swelled outwards with the volume I was displacing, and close against her skin, I felt the air hissing through Colette's body, trying to make room. Her thighs swelled temptingly against me, while her breasts grew fuller and rounder, pumped up with air that had nowhere else to go. Even her lips grew subtly fuller and more sensual as Colette writhed with desire beneath me, all the softer and more sensitive parts of her anatomy only too ready to accommodate however much I saw fit to fill her with.

“Oh my- I, I- you're almost there,” Colette breathed as I slid partway in between her massive breasts, “Just a little lower, a little- Oohhh!”

Just below her lushly distended belly and between her fulsome thighs, I had reached her achingly inflamed womanhood. I sheathed myself within her. I found, to my boundless delight, that Colette had been inflated just as much within as without, all her inmost parts squeezing arousingly inwards. I could see how being pumped up like this had made her so horny, even without me inside of her, her body had to be rubbing against itself in all sorts of ways that were impossible to resist. Just like the rest of her though, Colette's passion-moistened depths easily parted to let me in. She shuddered as I pushed in deeper, inch by inch, until, lying atop her massive belly and pressed between her swollen globes, I was all the way in. Already she was gasping for breath, her entire body quivering on the cusp of release. Slowly and tenderly I started, trying to be as gentle as I possibly could with my forswollen lover. I still couldn't get over how very right this felt despite being so completely unreal, the heat of Colette's skin against mine, the warm slickness of her tenderest flesh, even the way she jiggled beneath me was not entirely different from how sex with her had been before. It was just that everything now was exaggerated and amplified to the point where it was a challenge just to stay in control of myself. As spasms of ecstasy wracked her body, Colette's overfilled figure began to roll and sway. Still trying not to be too rough on her, I did my best to resist the near-overwhelming urge to just surrender all control and forget that she was inflated well beyond the point of safety.

“Come on,” she gasped, fighting for breath enough to speak, “I'm too horny to play around like this! I feel like if you don't fuck me good and hard, right now, I'm just going to explode!”

I gave her everything. Colette tilted her broad hips upward, and I went into her with utter abandon. The rhythmic rippling of Colette's body beneath me was soon replaced by the wild, rolling tremors than surged through her. Above her screams of ecstasy and her anguished pleas for more, I heard her breasts and belly creaking as the two of us strained them with reckless fervor. The rest of the world melted away; there was only Colette's vast and womanly form quaking against me, the thrill of thrusting deeper and deeper into the overstretched walls of her inmost self. I tried to last as long as I could as Colette was came countless times, the wonton, lust-tortured sound of her voice ever in the cacophony of sensations which flowed between us. All the while though, it was clear as her cries grew louder and louder, her movement more and more uncontrolled, that I knew she was building up to a climax that was mind-shattering in its intensity. I felt her tighten fiercely around me, convulsing violently. As I went with her and poured myself into her slick, tender depths, Colette screamed so loudly that the walls of the room seemed to shake around us, the groaning and creaking of her overinflated curves growing so loud that I wondered just how much pain there was mixed in with that echoing cry of release.

The storm passed. The motion of Colette's body calmed, her breasts still wobbling impressively as she caught her breath. Slipping out of her, I tried to pull myself even with her face, forcing apart her massive breasts to kiss her still plump lips.

“Mmm, that was amazing,” she sighed, her eyes nearly rolling back into her head, “It's a good thing I didn't know wonderful inflated sex was before now, or else I would have shoved an air hose down my throat and yanked off the valve years ago.”

“You're-you're the most incredible woman I've ever known,” I whispered, kissing Colette again, this time on her slightly softer cheek, “I don't know if this is a onetime thing, or if you want me to blow you up to a dozen times this size, but whatever it is that you want, I'm never going to question it again.”

“Hmm, good; I'm glad I finally convinced you,” Colette mumbled dreamily, “Right now though, why don't you just enjoy your big balloon girl a little more gently and let me get some sleep. It's been an awfully big day and I'm *yawn* tired.”

I kissed her again, feeling my own consciousness fading into sleep. Colette was warm and inviting beneath me, each deep, even breath she took making her breasts and belly to rise and subside by several inches. As we drifted off to sleep, satisfied and exhausted in the best of all possible ways, I heard Colette whisper a question.

“You'll make me bigger tomorrow then?” she sighed.

“For you, anything,” I answered.
