As Much as She Can Take, Part III

By: Kodos

“What do you mean, you're inflating again?” I asked, cluelessly; barely awake enough to talk, much less to understand what was going on.

“I mean I'm getting bigger; just look at my tits!” Colette insisted, glancing at her chest as if I was too dense to notice what was happening.

As if she even needed to remind me. It felt like about six in the morning; the room was still dim, but I could see Colette clearly enough sitting on the bed beside me. We had spent the evening indulging her inflation fetish, and she was now blown up to the point where she took up most of the mattress. Though not tall by any means, she sat nearly a foot higher than I did, her bulging behind lifting her up as if she was sitting on a pair of beanbag chairs that had been overstuffed until they were practically ready to burst their seams. She sat with her legs out in front of her, so lusciously plumped up from ass to ankles that she could hardly have bent them enough to sit any other way; just bending her knees slightly seemed to be all she could manage anymore. Her hips were every inch of five feet across, their skin stretched tightly around her generous curves by the enormous volume of air I had been pumping into her. As big as she was down below, I knew Colette's waist barely measured an inch more than in had before she'd ever found this bike pump that I had used to blow her up like this, but well, I couldn't see her waist, her soft little belly, or the way her ever so sensitive womanhood had been pumped up so full of air that even the slightest touch would make her come like a runaway train. Colette's boobs were in the way.

They were absolutely gigantic. I could hardly believe that just the day before Colette’s breasts had filled a C cup with room to spare. It seemed impossible that a pair of handfuls like hers could endure being enlarged to such massive proportions, but there they were, swollen into a pair of fat, lap-filling torpedoes. They covered her stomach completely, and had her hips been any less impressive Colette's entire lower body would have simply disappeared beneath her monstrous melons; even now her legs were buried to the knees. Despite being so titanic that Colette could only dream of reaching her nipples now her breasts rested almost weightlessly against her body and the bed.

“Come on, don't just stand there staring at my tits, can't you see they're getting bigger?” Colette asked impatiently.

“I dunno, they're already so huge you'd need to be filling up pretty quick for it to really show,” I said, still not entirely awake.

“But I can feel them getting bigger; don't you think I know what that feels like by now?” Colette asked, “Here, touch me here, you'll see.”

Leaning towards me, an act which set her swollen breasts wobbling invitingly, Colette grabbed my hands and pressed them firmly against her breasts. I was struck again by how soft they were, even after all I had put her through. I had spent most of last night pumping more and more air into my girlfriend, who, depending on her mood either demanded I inflate her until she was ready to pop, or begged submissively for me to keep going until she could hardly move. The bloated, watermelon-like shape of her breasts attested to how much pressure they were straining to hold, and Colette's nipples, puffed up like impossibly ripe and juicy strawberries, now throbbed faintly even when she wasn't playing with them, such was the sheer volume of air she had been forced to contain. Even now, though her smooth flesh yielded willingly, and from the way Colette stifled a little sigh at my touch, I knew that being stretched so extremely had left her inconceivably sensitive to pleasure.

“Mmm, there, do you feel it?” Colette asked again.

She was right, I could feel a faint sort of hissing sensation as more air was slowly flowed into her already-inflated figure.

“Damn, you are getting bigger,” I agreed, “What did you do?”

“I didn't do anything,” Colette said, fondling her breasts bemusedly. She narrowed her eyes and looked at me, “You're not doing this are you?”

“I don't even have the pump,” I protested, “I took it downstairs last night, remember?”

“I know,” Colette admitted, her sharp look softening, “I just thought maybe you set it up in the other room with a motor or something, so I'd just gradually keep getting bigger and bigger and bigger, until I couldn't even move, and you could just climb on top and fuck me senseless, with me blowing up like a life raft the whole time you were riding me.”

“What? No, nothing like that,” I insisted.

“Really?” Colette said with just a hint of disappointment, “Well, maybe next time then. Still that doesn't explain what's happening to me.”

“Maybe something's wrong with the pump,” I suggested, “We could go see if it's broken or something.”

“Ha, you go check on it,” Colette laughed, her mammoth rack bouncing appealingly, “Nothing I own is going to cover these monsters anymore, and can you imagine if Val came back to the sight of me, with an ass wider than a minivan and boobs so huge they'll get stuck in the doorway if I don't push them through one at a time? She's always thought I was crazy just for wanting to blown up like a balloon, I can't imagine how she'd react if she saw I'd actually gone and really done it. No, you'd better go, my twins are so tender already from being stretched out and pinched and squeezed last night that the last thing I need right now it so try to stuff myself into the hallway out there.”

On the off chance that Val had made it home last night, I pulled on some shorts and headed downstairs. Everything was quiet. I stepped into the front room. The pump was gone. The possibilities raced through my mind. Had someone broken into the house and stolen it? No, the door was still locked; nothing else was missing. Had someone taken back because we hadn't exactly followed the instructions? That seemed impossible, how would anyone even know how we'd used the pump? And besides, you can't go around handing that kind of thing out to people on the internet and not expect them to push their boundaries a bit. What could possibly have happened to- Then I saw them. A sodden set of clothes tossed haphazardly into the kitchen sink; a pair of mud-caked sneakers by the front door. Val had come back late last night; she must have taken it.

I ran back up the stairs to Colette's room, where I found her still sitting on the bed. Her bustline had gained a couple inches of since I went to look for the pump, and her expression suggested she hadn't quite decided to be more worried or turned on by this development.

“It's Val!” I shouted, startling Colette out of her reverie, “She came back last night and left some of her stuff; I think she took it with her!”

“What did she do?” Val asked, before realizing how it all fit together, “Damn, she had that big biking trip this weekend and it rained all last night. She must have come by to get some dry clothes, seen the pump and-”

“So she doesn't even know what she's got!” We both knew what was going on now, “She hasn't got any idea that it isn't just a regular pump; that every time she uses it she's inflating you even bigger than you already are!”

“But she said she was going with, like, all her friends on that fifty mile trail along the river,” Colette said, the seriousness of her situation settling in for her, “If they're all using that pump then- Oh, and I thought my tits hurt this morning; there's no telling how much air they're going to pump into me without even knowing it.”

“Well, hasn't she got her phone with her?” I asked, hoping the solution might be so simple, “Why don't you just call her and tell her what's going on?”

“What, tell her that she took my magic pump and the more she uses it the bigger my boobs and ass get?” Colette asked incredulously, “She'll think I've either lost my mind or that this is some sort of weird fetish thing for me, 'Please, Val, don't use that air pump; my huge, overinflated tits can barely take any more.' Yeah, that's not going to work.”

“Okay then, have you got a better idea?” I asked, watching as Colette slowly rose higher and higher where she sat, her bloated behind expanding beneath her as her massive breasts bloomed across the bed at a leisurely pace.

“Alright, point taken,” Colette conceded, each push of the distant pump now audibly hissing into her expanding figure, “Where's my phone?”

“I don't know; you haven't called anyone since I've been here,” I pointed out, drawing a sharp glance from my ever more voluptuous girlfriend, “Okay, sorry, that wasn't very helpful. Where do you think you used it last?”

“Crap, I can't remember,” Colette said, pressing her palms against her forehead, her elbows pushing twin indentations into the tightly drawn flesh of her bosom, “I dunno, downstairs, maybe?”

“Right, I'll go look,” I said, already heading for the door when Colette stopped me.

“Wait, I'd better come too,” she said as she struggled to climb out of bed, her cumbersome breasts quaking as she tried to stand without making them bounce too awkwardly, “If it's under the couch or something who knows how huge I'll be by the time you find it? If we're lucky I'll remember as soon as I get down there.”

“Wait, what if Val comes back while we're down there and sees you completely naked and blown up to size of a parade balloon?” I asked, “What would you even say to her?”

“Look, the fact is Val's seen me in the altogether before now, and well, knowing what she does about what I like, it's not exactly as if this is going to be a surprise for her,” Colette explained, rubbing her hands cautiously along the curve of her enticingly fertile hips, “Besides, I can feel the pressure growing inside me, accumulating, like I'm about to gain a lot more really soon if we don't stop this somehow.”

“What like someone isn't pushing the pump handle down all the way again?” I asked.

“It feels, different somehow,” Colette explained, now cupping her pleasure-stretched breasts with hands far too small to contain their bounty, “Maybe it's because the pump is so much farther away or something; I don't know. All I know is that right now I'm a lot less worried about Val coming home and walking in on her huge, balloon, fucktoy roommate in the living room than I'm worried that she's going to be out the rest of the day doing this to me!”

“Okay, good point,” I admitted, the growing note of alarm in Colette's voice convincing me, “You can still fit down the stairs right?”

“I think I'm probably a bit broader than the hallway, actually,” Colette said, appraising her reflection in the full-length mirror on the closet door, “But I'm still soft enough I think I can jam my fat boobs through well enough to get downstairs. You'd better let me go first though; I might need a push if I get stuck.”

Having made her decision Colette turned and made for the door. As she turned away I realized just how much bigger she had gotten since Val had got ahold of the pump. I had thought Colette's ass was gigantic before but now, from behind she was just unreal. Just below her narrow waist, her figure flared outwards so alarmingly that I remembered just how serious Colette's condition could easily become. Her spectacular ass overwhelmed her plump thighs almost to her knees, and the way it swayed and quivered as Colette moved made it hard to resist the idea of just tackling her, knocking her down on top of her huge boobs and just pounding her until we both passed out from exhaustion. I only stopped myself at the thought that Colette would kill me if I tried something like that right now, or worse, that she'd go along with it all too willingly.

With a sound like a wet balloon being squeezed, Colette stuffed herself through the door and into the hallway. As she pushed her way down the stairs her overfilled ass jiggled with lusciousness, brushing back and forth against the narrow walls as she descended, Colette's full flesh bouncing hypnotically as she moved.

“Don't even think about giving me a pinch right now,” Colette called over her shoulder with less than complete seriousness.

What? I wouldn't even think of such a thing at a time like this?” I protested as she flashed a smile at me.

Every step Colette took set her entire body atremble, and as she was so patently unable to see her feet or the stairway before her, she gripped the bannister tightly. With her other arm Colette vainly tried to clutch her enormous boobs to her chest; if anything they bounced even more than her rear, and Colette winced in obvious discomfort when one of her still-tender boobs smacked against the close-pressing wall particularly loudly.

“Ow, fuck!” Colette exclaimed, pausing to rub the side of her breast, “These things are starting to get really sensitive.”

“Does it hurt much?” I asked.

“Well, yeah, it does, but it's not really that pain that's getting to me,” Colette said as we finally reached the front room, “It's more like, well, it feels like all the nerves in my skin are just stretched so tight now that even stuff that hurts is starting to turn me on. I mean, not like I was planning on walking down the street like this anyway, but how am I supposed to do anything if just slapping my tits against the wall gets me all wet?”

“We'd better find your phone,” I said.

“Right, damn, where was it?” Colette asked, planting her hands against her expansive hips as she surveyed the house, “That weird feeling is getting stronger again; we'd better hurry.”

A moment later we were both turning the room upside down searching for her phone. As I picked through the stack of mail piled on the kitchen counter, Colette stood by the window, her large purse jammed between her low-hanging melons, feverishly pawing through it for her phone.

“Okay, I should have known that would be too easy,” Colette muttered to herself as she dumped out the purse's contents and hurried awkwardly to the desk, her haste only amplifying her growing tendency to jiggle, “Damn but getting anything done at this size is harder than I thought it would be.”

“Well, your boobs are nearly as wide as you are tall,” I pointed out, “What did you expect?”

“I don't know, I just didn't expect them to be so- so unwieldy,” Colette sighed, hefting her massive bosom wearily, “I guess I always figured that being full of air meant they wouldn't be any harder to get around with, just, you know, bigger. But just walking is so much harder now; they keep slapping into each other, my body, the furniture, everything! It's like trying to steer with a couple of hot air balloons strapped to my chest. And my ass, it's just sort of out there now; everything south of my waist is just like 'Bloomp!' I can't even pick something up now without figuring out if I'm just too freaking huge around the middle to reach it!”

“Would you rather be back to normal?” I asked, sifting through the pile of laundry on the sofa, “I mean, if we get the pump back and don't use it for a while I bet this'll start to wear off, well, some of it anyway.”

“But that's the thing, I like being this huge,” Colette said, “It's so much better than I ever dreamed it could be. The sex alone is mind-blowing enough to make it worth never being able to see my feet again, but this whole inflation thing has been such a turn-on of mine for so long that even just standing here, feeling how far out my body goes now- it's not just the physical things, being all sensitive and all that that make me hot; just the thought of how huge I've let myself become, the sight of my tits hanging off my chest, so swollen, so completely filled with air I could almost come without anyone so much as laying a finger on me.”

“Well, don't worry about knocking over a few lamps then,” I suggested, “In a few days you'll get used to being this size; you'll learn how to get around and then you'll just have the fun bits to keep you occupied.”

“You're probably right,” Colette allowed, kneeling on the floor, her gigantic ass swelling out beneath her weight as her expansive breasts spread out, resting lightly on the carpet in front of her, “I guess I'm just freaked out by the pump disappearing. It's one thing to be safe with you, knowing that you're not going to blow me up with more than I can take, but even if I want to get bigger than I already am- and believe me, I'm already so addicted to getting bigger- but not being able to control it at all is kind of frightening. Give me a second here, that weird feeling just came back; I feel all lightheaded. How big was I when we came down here? I think I'm starting to blow up faster.”

Colette was breathing more heavily now, I could hear her struggling to overcome the wave of dizziness that had swept over her as I desperately tried to figure out where her phone could be, looking in the fridge, checking to see she had left in in the pantry in a moment of absent-mindedness. I heard Colette sigh with exertion, and the faint stretching sound that now came whenever she suffered a particularly powerful rush of growth. I turned to see what had happened and found myself transfixed. Colette had somehow wedged her head and arms underneath the sofa. Pressing her chest so close to the floor forced her breasts outwards at a painfully sharp angle, pushed out to either side of her body and somehow looking even more obscenely distended than before now that they weren't hanging down against her body. Colette's ass was thrust high in the air behind her, her feet and even her plumped up thighs overshadowed by its spectacular dimensions. Her breasts, already under enormous pressure, throbbed visibly from being squashed so harshly against the carpet, while her lusciously overfilled ass trembled invitingly as she tried to reach further beneath the couch.

“Er, are you okay down there?” I asked, trying to resist the urge to just take her from behind, even if it meant that Colette was inflated into sheer immobility. I contented myself with stroking the smooth skin of her breast, running my fingers lightly along her pert, rosy nipple.

“I think I see my phone down here,” Colette said as I touched her, “I just can't quite- Ahhh, oh fuck! Come on, you have no idea how horny that's making me! Be serous here for two seconds and help me reach this damn thing.”

“Okay, okay, sorry,” I mumbled apologetically, “What do you want me to do?”

“Here, come around the couch from the back and see if you can't reach it better,” came Colette's muffled reply, her spectacular figure still wobbling enticingly as she tried to reach for the phone.

I hurried around to the other side and reached beneath the sofa. It was dark and dusty, and I could hear Colette's labored breathing as I pawed around blindly.

“No, over this way, where I'm reaching,” Colette said, like I could see where she meant, “Here more over toward the end there.”

Trying to guess I reached out and felt something smooth and plastic brush against my hand. I reached out and grabbed the phone.

“Okay, I got it,” I called triumphantly, standing back up as I watched Colette struggle free from the other side of the sofa.

“Damn, how many tires is she blowing up anyway?” Colette muttered as she crawled backwards and tried to stand up, “I feel like I've gained another six inches just since we got down here. Here, give me the phone before Val turns me into the Goodyear blimp.”

I quickly handed her the phone, and Colette hurriedly mashed in her housemate's number before holding the phone to her ear with a look of growing concern of her face, her breasts so immense now that even standing up they almost completely filled the couch in front of her. Though they were still growing gradually, their expansion was relentless, and even as Colette stood there waiting for Val to pick up I watched the upper curve of her bust slowly rising higher and higher.

“Damn her, why is she not picking up?” Colette yelled, looking for the moment as is she very much wanted to throw her phone across the room, “Is she so busy turning me into a parade balloon that she doesn't have time to answer her stupid phone?”

“Come on, hon, it's not like she knows what that pump is doing to you,” I said, not sure what I'd do with Colette if she really lost her temper, “Here, give me the phone; let me see if she picks up this time.”

With a sigh Colette leaned forwards and handed the phone back to me and absent-mindedly started rubbing her rear, her hourglass figure growing more and more exaggerated while I watched. I hit redial and waited, but it was only a second later when I heard Val's voice.

“Hi, this is Valerie, and I can't answer my phone right now,” the voice chirped, “Please leave me a message and I'll call ya right back as soon as I can!”

“Crap, straight to voice mail,” I said.

“What? She turned her fucking phone off?” Colette cried, “Doesn't she have any clue what her biking trip is doing to me? What the hell am I supposed to do now, just sit around until I get so huge I just fill up the whole house?”

“Stay calm, she's probably just way out in the sticks where there's no reception,” I said, as persuasively as I could, “Besides, even if we can't get in touch with her, it doesn't need to be the end of the world. I mean, if she's just blowing up a couple of bike tires what's the worry? You wanted me to inflate you with way more than that today anyway; we can just have a fun morning together even if you end up a little bigger than you'd planned for, and when Val gets back this evening we'll get the pump and everything will be fine.”

“But if she's just doing a couple of tires, why have I been getting bigger for the last fifteen minutes?” Colette asked, lifting her breasts and pushing them towards me as if otherwise I might have missed them, “And besides, do you know how much pressure a bike tire takes? Some of them go up to sixty pounds! Now, I'll admit I don't know exactly how much I've got in me right now, but 60 psi- even assuming I can hold that much pressure, I'll be too huge to even move! My tits will be stretched so tight they'll be ready to burst and I'll be so horny I won't even be able to think straight!”

“But last night, I thought you said that's what you wanted,” I said.

“Well, yeah, but that was from you!” Colette exclaimed, “Having you pumping me up right to my limits got me all turned on because that's always been my fantasy, and I knew that no matter how much I called out for more, even if I begged you to give me more than I could take that you'd still be gentle and not let anything really dangerous happen to me. I felt like I could lose control because I knew that you'd always be there to control me, or at least how much I was willing to take, but this, I just don't know what's going to happen and it scares me! I could stop expanding right this second and stay this size until Val gets home tonight, or she could keep pumping away until I explode! It's just, I wanted to get all freaky, just with you, not quite like this, not all at once.”

“It's okay, hon, we're going to get you through this and you're going to be alright, even if you do end up growing a little bigger than you're ready for just yet,” I said as comfortingly as I could, pressing redial on Colette's phone, “Here, I'm going to call Val again and leave a message so if she does find her way back to civilization she might get it and stop using the pump.”

“That's- that's a good idea. Geez, I think I let myself get too worked up just now, I think I pushed myself to far,” Colette sighed as she sank to her knees, her huge rump bulging out beneath her weigh as she sat down on it, the skin of her swollen breasts sounding odd against the corduroy fabric of the sofa cushions, “You take such good care of me. Just so you know, if Val does stay out all day with the pump and I do end up so enormous I can't even carry my boobs around without your help, and the pressure's so much that I creak like a balloon about to pop every time I twitch a muscle and I'm so awfully tight and swollen inside that every time we have sex I end up screaming until I pass out- well, even if all that happens, I meant all of what I said last night. I want to be huge and I want to be with you, and if it happens a lot sooner and a lot faster than I was planning on, it's still going to be absolutely incredible.”

“I hope it won't come to that just yet,” I said as I waited for the recording to finish, “but no matter how huge you get, I'm only going to find you that much sexier.”

“Okay, this is going to sound crazy, but I'm dead serious about this; you need to listen to me,” I said as Val's voice gave way to the beep, “You know that pump that you took from the house last night? You have to stop using it, like, right now. I'm not even going to try and explain right now because it's just too weird; you'll have to wait until you get back here and see Colette. Please though, as soon as you get this message, stop using that air pump, it's, well, it's not safe; that's all I can say right now. Just trust me on this one. I've got Colette's phone, so if you can call us, I'll be able to explain.”

“Uh-oh, I think something's starting to happen,” Colette said, still sounding a little dazed as she tried to stand back up, “I think it's more than just my tits and ass this time.”

“What do you mean?” I asked, worried by the strange calmness of Colette's voice, “What does it feel like?”

“I dunno- it's just, different somehow” Colette said, giving a shrug as she struggled to her feet, “I feel, weird, like I'm supposed to be blowing up way faster than I am. It's like there's all this air rushing into me but it isn't getting- Oh!”

“What's wrong?” I asked as Colette's legs buckled beneath her again, sending her jigglesome figure back to her knees.

“Oh, oh fuck, I've never felt it like this before,” Colette breathed, “Oh, it's really happening this time- I can't- oh my-”

Even as her words trailed off I could see what was happening. It was like a valve had been opened up somewhere, and the slow whisper of air that had been flowing into Colette's body all morning suddenly turned into a flood so powerful that she may have just as well wrapped her lips around the hose of an air compressor. With an unwilling creak, her breasts swelled up, spreading wider and wider as Colette's trembling body inflated with air. On her knees before me and completely helpless to resist what was happening to her, Colette slowly rose up higher, her ass expanding larger and larger beneath her. Looking down on her, I could see it billowing out voluptuously, the smooth, graceful curve of her back interrupted at her waist by a vast and growing expanse of quivering flesh that hid her legs and feet entirely now. Colette's knees too, were covered completely by her colossal bust, the worn carpet rubbing audibly against the tender underside of her bosom as her breasts ballooned out in front of her.

“Please, you've got to get me upstairs,” Colette cried desperately, shivering from the overwhelming sensations coursing through her body.

“Can you stand?” I asked, paralyzed for the moment with a mix of concern for my girlfriend and sheer awe at what was happening to her.

“No, I can't,” Colette sighed, her voice hardly more than a whisper, “Please, you have to get me upstairs to my room.”

“But how? You barely fit down the stairs before,” I said, searching vainly for something to say that would calm her from her near panic, “Why not just stay here? There's no telling how big you'll be by the time this stops; wouldn't it be safer to be downstairs where there's more room?”

“Not here,” Colette pleaded, almost delirious now, here breasts still getting bigger by the second, “I'll be safe in my room; drag me upstairs if you have to, I'll be okay- just hurry before I'm so huge I won't fit anymore.”

“Okay,” I agreed reluctantly, “I just hope you know what you're saying.”

I stepped behind Colette, marveling as I did so at how spectacular her body had become. She sat as high as if she were perched on a pair of exceedingly overstuffed beanbag chairs, and looking over her shoulder I saw the boundless expanse of pale breastflesh stretching farther and farther in front of her. She reached her arms upwards and back; I grabbed her hands and pulled. She leaned back further and further in response, her inflated rear groaning slightly as she did so, her breasts thrusting out prodigiously as they lifted off the floor. Summoning all her strength, Colette managed to straighten her legs just enough that when they failed her again a second later she fell backwards, her ass bulging alarmingly from the impact as she landed on it.

I pulled harder, and with the sound of her swollen rear rubbing along the carpet I dragged Colette towards the stairs. She moaned with discomfort; I slowed down, worried I was hurting her. When we reached the steps I tried to pull her up as tenderly as I possibly could. Bloomp, bloomp, Colette's wide-spreading hips sounded so full as they pressed against and between the bannister supports. I wondered how rough the wallpaper felt against Colette's skin; I could hear it rubbing against her ever-widening form.

Filled with air though she was, I found that dragging her upstairs like this was still anything but easy. Even though she weighed the same as always, I'm not really the strongest guy out there, and Colette, well, she wasn't exactly a slender little chit of a girl before we went and blew her up with enough air to fill a weather balloon. Even so, I'd helped carry her home after enough late nights out to know that it was more than the fact that she had gone very nearly limp from the violent surge of air rushing into her body; the friction of the walls was making my job harder by the moment.

Colette's breasts bulged out nearly five feet in front of her body now, the narrow walls squeezing them like a vise, one that was only growing tighter as she continued to inflate.

“Oh, fuck, it's getting so tight in here,” Colette moaned as I struggled to drag her up the steps, “I can feel it everywhere now; I'm starting to blow up all over!”

Even with her entire lower body hidden below her voluminous bust, I saw that she was right. Colette's arms, which hadn't exactly been bony to start out with, were starting to thicken. It was most obvious closest to her shoulders, though as I watched, I realized her arms seemed to be plumping up all the way to her wrists. Her shoulders themselves looked to be getting fuller and softer, as if the rest of her body was finally trying to catch up with her more spectacularly expanded regions. If I had any doubts about the air flowing into the lower regions of her anatomy, they were laid to rest as Colette burst forth with a ragged cry of ecstasy.

“I'm coming so hard; you have to hurry; pull me harder!” she begged, her entire body trembling with barely-contained pleasure, “It's getting so tight I can hardly take it!”

I could almost hear the plaster cracking as the mounting pressure within Colette's body grew. As I hauled her over the top step and towards her bedroom door, I heard her kicking her feet weakly, desperate to do anything she could to help get herself somewhere with enough room to accommodate her overinflated figure somewhere where she wasn't in danger of being smothered by the walls and her own distended breasts.

Her arms had plumped up to the point where they looked like they belonged to a woman of at least three hundred pounds now; from her elbows to her shoulders they now jiggled almost as much as the rest of Colette's overfilled physique. Gasping for air and moaning with pleasure, Colette let her head hang back as far as she could, the tight press of her expanding cleavage still threatening her very ability to breathe.

My back was aching and my arms felt wholly drained of strength as we finally reached her door. Colette wasn't the only one fighting for air as I struggled to gather myself for this one final effort. Even a couple of seconds spent recovering though made it clear that Colette's condition was one which would not wait.

“Oh, what are you waiting for?” Colette cried over the stretching sound of her body expanding against the hallway, her cry punctuated by the crack of plaster surrendering as her dangerously confined breasts billowed up to the point where I could hardly see beyond them, “Please! I can't take much more, the pressure's just too much! You have to pull me through now!”

“Okay, but this is going to be a tight fit,” I warned her, steeling myself as I grabbed her hands so tightly that I could see my knuckles going white, “Hold on, this is going to pinch a bit!”

And without waiting for her answer I threw myself through her bedroom door with all the strength I could muster. What happened next was a blur. I pulled her into the room down to her shoulders, and for a moment it seemed I had failed, that Colette had already become too immense to fit through the doorway. As second later, along with the sound of creaking wood, I saw her gigantic boobs fairly burst through the doorway. Still holding on to Colette I kept pulling, hardly even noticing her screams of excruciating bliss as I drew her hips through the narrow opening, forcing unknowable volumes of air into parts of her anatomy already stretched to debilitating sensitivity.

At last she popped free of the door. I fell backwards to the floor, Colette coming to rest with her head in my lap as the air contained within her, finally freed from the narrow hallway, expanded to a more comfortable volume. I could hear the air whooshing inside of her body now, all Colette's more voluptuous regions quivering submissively as the same pressure which had nearly gotten her stuck in the hallway now rapidly caused her to balloon to dimensions that I could barely believe I was seeing.

Colette's eyes were closed; she sighed and murmured faintly, parting her lusciously plump red lips as she writhed weakly with unbearable ecstasy. I couldn't tell if she even knew I was there anymore, or if she was simply too absorbed in the pleasures of her irresistibly swollen figure to do anything but submit to the sheer bliss of her condition.

Freed from the confines of the constricting hallway, Colette's breasts ballooned uncontrollably. Each one already bloated wider than her outstretched arms, they grew larger and larger as the pressure within them overcame any remaining resistance her overstretched skin might have offered. Afraid that in her current state, Colette might easily be smothered beneath her expanding mammaries, I tried to spread them apart, opening up a valley between her two rising mountains. I realized that it wasn't just the growth of her breasts that was pushing them upwards; Colette had been right about blowing up all over, her belly, only slightly chubby half an hour before, had grown to the point where she looked fully nine months pregnant. It swelled submissively, as if being blown up the night before had left Colette's middle enticingly stretchable, her figure fast moving beyond any conceivable dimensions of simple maternity and into the realm of bodies unattainable by any natural biology. As her belly continued to inflate it pushed Colette's breasts all the more insistently upwards, until her cleavage threatened to envelop me as I leaned in to keep Colette's face free from her distending bosom.

My legs were buried beneath Colette's spectacularly swollen figure now; I could feel her ass expanding larger and larger as the volume of air within her steadily increased. Beyond the ever more fulsome curves of her chest and belly I watched as her hips filled until she was almost a caricature of the female form, spreading wider and wider as her entire body blew up like a balloon that someone had attached to a very full air tank and then utterly abandoned. Her obscenely plump legs splayed apart farther and farther as the growing curve of her vast belly forced itself between them. Even in her delirium she was trying to work her fat arms down past her titanic boobs and around her bloated belly, whimpering in frustration now that she had grown too immense to reach her own lust-sodden depths. She had already been so absolutely swollen down there before, I could only imagine what this latest round of inflation was doing to her, her lips were surely inflated nearly to bursting, her most sensitive skin stretched more tightly than any woman, even one so consumed with lust as Colette, could possibly stand, her entire body teetering on the cusp of one final explosive climax.

Even without being able to reach herself, the sheer intensity of sensations flooding through her overwhelmed body seemed at last to reach critical mass, and Colette came. Screaming, moaning, crying out inarticulate sounds of excruciating delight Colette surrendered completely to her urges. Her final loss of control let one great final gush of air force its way into her body; her arms twitched weakly and her legs spread as wide as she could bear as she expanded even more. Her gigantic breasts pressed tightly against each other once again, Colette's ballooning belly once more hidden from my sight. Her vast tits quivered with excess, their naked skin, slick with her sweat, pressed against my face as I struggled to push them down away from her face. I felt a deep, urgent throbbing, confined within her taut, yielding flesh, and as Colette gave one last sigh of exhausted satisfaction, her expansion seemed to stop.

“Hon, are you okay? Can you hear me?” I asked, pressing my palm to her cheek and wondering what kind of state she was going to be in having endured this latest bout of runaway inflation.

“Wha-? What happened?” Colette murmured dreamily, her eyelids fluttering faintly but not yet opening, “Where am I?”

“You're okay, we made it up to your room after you started to blow up all of a sudden,” I explained as calmly as I could, “I don't know exactly what happened, it's like the pump being so far away slowed down how fast it could blow you up, almost like someone was standing on the hose or something. I don't know what changed though; maybe Val finally brought it back close enough that it could force everything into you in a couple of minutes, or maybe it just took it longer to connect to you again. Honestly, I'm just as confused as you are, well, maybe not quite as confused; are you sure you're okay?”

“Hmm, well, that makes as much sense as anything to me,” Colette said, looking up at me now, her eyes focusing on the world again, her hands beginning to explore her exorbitantly enlarged figure, “Oh my- just how big am I now?”

“Um, I'm not exactly sure,” I admitted, relieved that she didn't seem to have lost her mind or anything, “I've kind of been stuck here trying to keep you from being suffocated by your own boobs; I'm really not sure what condition the rest of you is in.”

“Well, here, I can keep my tits out of my face now,” Colette said, planting her hands firmly on them and mashing her overinflated zeppelins down forcefully, “Oh! Damn, I didn't think they could get any more sensitive! Here, why don't you try and help stand me up so we can see what I've got to work with now?”

Even if she still weighed the same as she always had, it was no easy task lifting my stunningly overinflated girlfriend to her feet. Anything that involved me being in front of her was simply out of the question; Nearly two yards of tremulous pale flesh projected out in front of her, and even if I managed to slip in between Colette's massive boobs, there was still the matter of her belly, swollen now to a size fully ten times that of any pregnancy. Lifting her up from behind was no simple trick either. Even with Colette cooperating as much as she was able to in her distended condition, lifting her by her indecently plumped up arms only got her halfway to her feet before the sheer immensity of her rear made it almost impossible for me to keep pulling while still leaning forward far enough to actually do any really lifting.

“C'mon, pull harder!” Colette cried, her forswollen behind squeezing against me in a way that made it very hard to focus on getting her standing, “I'm no fatter than I was before; put your back into it!”

“That's easy for you to say,” I managed, “If you're so damn skinny then why do you need me to pick you up off the floor?”

“Hey now, my legs are so thick I can barely bend my knees,” Colette pointed out, though I did notice she was finally making an effort to stand as well, “Oh- ohh, if you want any more help from me you'd better be gentle, I'm so swollen inside I can't imagine what I'll do if I have to take any more pressure.

“Hmm, that tender, eh?” I asked with a smile, pulling Colette towards me roughly, savoring the way her enormous ass felt against me, almost hypnotized by the way her boobs and belly ballooned out so lusciously wide in front of her body.

“Ohh, yes, just like that- fuck! Stop getting me all turned on!” Colette insisted, half-heartedly wriggling free of my grasp as she finally got her feet beneath her, “Just give me a minute to- oh.”

“What? Are you okay?” I asked, taken aback by Colette's sudden silence.

“Holy crap, am I really that huge?” she asked, dazedly staring at the mirror on the wall in front of her, “I mean, it's not just me right, I really am as big as I look?”

“I dunno, the view from back here is pretty impressive,” I allowed, giving her an approving smack on her ass, “If you want my opinion of everything else, you're going to have to turn around and give me a better look.”

“Jeez, just moving my legs is so hard now,” Colette complained, laboring to turn towards me, “and if I don't keep my back straight my belly is going to be rubbing against the floor.”

As she turned to face me, I could only see just how right she was, staring in awe at just how immense this last round of inflation had left her. As Colette moved, I finally witnessed her spectacular figure in profile, desperately more expanded than I had imagined while I was trying to drag her up the stairs. Her ass swelled out behind her enormously, so immeasurably round that even her luscious thighs seemed modest in comparison. And Colette's thighs were far from easy to overwhelm, each one swollen to such excessive voluptuousness that I wasn't sure I'd be able to wrap my arms around one of them, though I found myself hoping fervently that they had not become so terrifically overfilled for Colette to wrap them around me.

True to her words, I saw that Colette was having to lean back slightly to keep her belly from rubbing against the floor, and I could only imagine how it would feel for the utterly overstretched and tender skin of her underbelly to chafe against the well-worn carpet. Even leaning back though, left her with only the barest inches of space between the underside of her five-foot sphere of a belly and the floor, and the fact that she remained tantalizingly bouncy meant that I caught her gritting her teeth more than once as she painstakingly moved. Though the lower hemisphere of her belly was laid absolutely bare, its upper latitudes were entirely obscured by Colette's obscenely overinflated breasts. They were almost indescribably enormous, each one now far too wide to fit through her bedroom door; her nipples now swollen like a pair of ripe tomatoes, standing proudly, almost painfully taut against the vast expanse of Colette's inflated bosom. Though her breasts still looked like they had some tendency to the torpedo-like shape they had been filled to before, the sheer volume of air now throbbing had distended them in far more spherical directions, as nearly weightless as they were immense. They bounced lightly against her huge belly as she breathed, trembling at the sight of her own reflection, so huge that if she got any larger at all Colette would find it difficult to even see over her expansive front.

“Oh-I look like I'm ready to pop!” Colette sighed in awe, “I mean, I knew I was getting big but this, this is just, wow.”

“Does it hurt?” I asked, worried about my titanic girlfriend's safety, “I mean, other than everything being all super sensitive?”

“Other than that?” Colette echoed, her lips parting in a mischievous smile as she caressed her pneumatic curves longingly, “Actually, that's the best part. Every single inch of me just feels so replete with potential. I feel like if you so much as pinched one of my poor, swollen nipples right now I'd come so hard that people half a mile away would hear me screaming. I can't even begin to describe how all the pressure in my belly is pushing inward on me. I'm already so terribly tight down there; you'd have to be ever so hard just to force your way inside me. My ass is just so big I can hardly even wrap my mind around it; I can feel it wobbling back there every time I move, like it just goes on forever. And my tits! Somehow in the back of my mind I always thought blowing them up to this size would be too much, that as completely fucking hot it was to imagine having a rack this huge in real life would just be more than I could take somehow, like they'd just be so completely stretched out by now that I'd be begging for mercy, my poor boobs filled to bursting so that even the slightest touch would make me freak out. I never thought that it would actually be like this!”

“Be like what?” I asked, worried that the strain on Colette's body might be affecting her mind somehow, “It doesn't hurt, does it?”

“Oh, no, it feels amazing,” Colette breathed, her eyes, closing and a shudder racing through her immense figure as she gave her bosom a lustful squeeze, “It's so, so much better than I even imagined; I don't even have the words. Honestly, now that I'm this big I think I still want more.”

“More, already?” I asked startled at Colette's admission so soon after being inflated to such an alarming, if alluring size.

“Oh, I know I shouldn't be so eager,” she said with feigned modesty, “I just feel so sexy like this, and so ridiculously horny, I can't stop imagining how much better it will feel when I get even bigger. I think I'd lose my mind if you fucked me right now; but I'm just too obsessed with the idea of you riding me when I've been blown up twice as big. Just think about it, each of my tits inflated to the point where they almost touch the ceiling, filled with so much that I'd be positively afraid to breathe. My belly would have me absolutely immobile; I'd either be buried underneath it with my boobs, or laying on top of it, so massive and round, it lifting my plump legs so far off the floor that I'd be absolutely helpless, my huge ass jiggling in the air. You could take me rough if you wanted; right now I could barely waddle away if you tried to force me into anything, or if you tried to force anything into me, but I'd be so enormous I'd be completely at your mercy. The most I'd be able to do is beg you to be gentle, pleading with you over the sound of my huge tits creaking and stretching. If you really handled me well I might even end up so delirious with pleasure that I'd beg you to make me even bigger.”

“All that and you'd still want more?” I asked, half in disbelief, half excited by the very thought of pushing Colette to the point where all she could think of was getting bigger, even with her body already straining with excess.

“Don't worry; I'd make you work for it,” Colette assured me with a wink, “But after you finished fucking me, I'm sure I'd wake up hours later, my boobs still just aching from what you'd done to me, still sore from you forcing yourself into my overinflated body, but I just wouldn't be able to resist. I'd call for you; you'd wake up to the sound of me pleading for you to give me more. You might take some convincing; you've always been so thoughtful with me, and I'm sure the sight of me lying there, already pumped full to bursting and still longing for more might give you pause. But even if I were far too big to do more than tremble helplessly in place, I think I could win you over. You'd come to me, drawn in by my irresistibly luscious figure; knowing just as well as I did that it would be insane for burden me with even the tiniest bit more, expanded as I am to the point where just a single pump might be more than I could bear. Still, when you came close to me, felt all those acres of my soft, yielding, vulnerable flesh, just quivering at the slightest touch, you wouldn't be able to stop yourself. When I drew you in to kiss me, your lips pressed tightly against mine, my desperately overinflated tits squeezing you tightly between them, you'd want me to be bigger still. I wouldn't need to say a word; you'd just pick up the pump and go to work. Even if I begged for you to stop, each push of that handle leaving me more and more dangerously overfilled, we both know we'd never really be satisfied until you took me to the utter limit of what I could hold. But enough about my fantasies; come here.”

What?” I asked cluelessly, surprised by Colette's sudden request.

“You heard me, come here,” she repeated, beckoning me over, “I don't know if Val if going to blow me up until I fill up this whole room or if you're going to have to do that to me later; but I'm so horny right now I feel like I could pop all on my own if we don't get started soon, so get over here so we can fool around a little before I make you fuck me senseless.”

What could I say to that? I came to her. As I drew close, Colette reached out to pull me in. She leaned forward, the underside of her belly rubbing against the floor as she stretched her plump arms out towards me. With a cry of surprise she lost her balance completely, falling forwards until her body was supported entirely by her boobs and belly, all gently bulging outward from her weight, creaking faintly as she kicked her legs weakly, her enormous ass jiggling as she did so. Colette had been filled with so much air by now that even laying on her front her face was nearly level with mine. She smiled a concupiscent smile at me, squeezing the huge pair of melons she now rode on top of appreciatively.

“Well, what are you waiting for?” Colette asked with just the faintest hint of concern, “Come closer; I want you to kiss me; I want to feel your big, hard cock throbbing between my huge, aching titties. I want you to take to the very edge, tease me until I'm begging you to take me, and then I want you to fuck me- fuck me until my big, swollen breasts are sore from rubbing against the floor, until I'm screaming for mercy, begging you to come because I just can't take any more. Come on, don't torture me like this; I'm so hungry for it I can hardly stand it!”

Who was I to stand there and watch her suffer? I stepped into Colette's expansive cleavage, her enticingly inflated breasts squeezing against me from either side. They seemed to throb faintly in time with her breath, and she inclined her face towards mine as I drew close. As soon as I was within reach she pulled me in with her air-plumped arms and held my mouth eagerly to hers. Our lips met; hers feeling seductively full and sensuous against mine, her tongue already probing as she kissed me passionately. Within moments I was ready to give her anything she was willing to take, plunging deep between her billowing mountains, Colette's sweat-moistened skin slippery and welcoming against me. After another long, breathless moment, she pulled back for a moment and smiled invitingly.

“Well, that didn't take long,” she whispered, inches away from me, her breath warm against me face, “Be careful where you poke that thing though; my poor tits are so swollen and full I feel like you could pop me if you jabbed me in the wrong place.”

“Oh? Well you know how much I'd hate to hurt these zeppelins of yours,” I said with feigned concern, “So if taking advantage of your big balloons like this is the wrong place, why don't you tell me where the right one is?”

“Ohh- I don't think you need me to help you figure that out,” Colette breathed, her voice faltering as if she were so close to climax that she could barely form the words, “I'm already so tight I can hardly stand it; like every last bit of air inside me is just pushing against me from the inside. But you've gone and gotten me so hot now, you wouldn't believe how slick and wet I am inside right now. Don't worry though, I've always got room for you, love; even if you blow me up to the point where I'm afraid to even breathe, I'll always be ready to welcome you inside. So come on, don't keep me waiting; Just one good push and you'll slide right in. I'm already so horny- I'll probably be screaming before the second thrust, but don't you worry about me; I'll be loving every second of it. Fuck me as long as you can, and give it to me good and hard, no matter how loud I get, no matter how much you hear my overfilled tits creaking and stretching while you pound me. I want you to ride me until I'm ready to pass out, until I'm so filled up with pleasure that I'm ready to explode, and then, when you just can't hold back any longer, when I've got you so hard it hurts, then I want you to come. I want to feel you just pumping it into me, fucking me within an inch of my life, filling me up with all you've got to give and not stopping until we're both so utterly, wonderfully spent that neither of us even has enough strength to move until the morning. Can you do that for me?”

I had never been so ready in my life. Together, we had given Colette the body she had always fantasized about, and I was ready to take her and consummate all her deepest desires. She looked into my eyes pleadingly as I pulled away, ready to give her exactly what she longer for.

There was a knock at the bedroom door.

“Oh, fuck; it's Val!” Colette said, startled and glaring at the door, “She sounds pissed.”

“What do we do?” I asked, the thought of Val walking in on us in such a state suddenly feeling more than a little embarrassing.

“Come on!” came Val's voice from the other side, “I came all the way back here because of your stupid phone call, now open the hell up and let me in!”

“Quick, put on some pants and go meet her,” Colette urged me, “She'll freak out if she comes in and sees me like this, but maybe if you go out there and tell her, I dunno, something, she'll just hand over the pump and leave us alone.”

“What am I supposed to tell her?” I asked as I struggled into my pants, doing my best to hide the obvious signs that we had been getting pretty steamy about three seconds before.

“I don't know, just make something up,” Colette hissed, “Tell her I'm drunk, tell her I'm naked, tell her anything, but just get the pump and tell her to leave us alone.”

Feeling more than a little unready for this sudden change in plans, I shrugged and moved stepped to the door. Before I could get there there was another angry knock, the knob began to turn, and just as Val pushed it open I slipped through and into the hall, shutting it so hurriedly behind that before I knew it, I was standing there in the dim light with Colette's very irritated flatmate about two inches away from me.

“And I knew it was for something kinky,” Val sighed, gesturing at me with the air pump, “All this way back, leaving the rest of my group and all this so you two could screw around and pretend like she's a balloon or whatever.”

“No, wait, um, it's not like that,” I explained, still not sure exactly where my line of reasoning was going to lead, “I mean, I'm not gonna lie, we were um, playing around and the pump, well, it was part of the game and we-”

“Shut up and stop blithering!” Val said with exasperation, “Did I or did I not just come all the way back here from the river just to bring you what passes for a sex toy in you and Colette's weird, fucked up relationship?”

“Well, yes, but it's not like that,” I said, hitting upon what seemed at the time like a good line of attack, “You see, Colette's drunk, I mean high, and she got some bad stuff from some guy out on Grace Street by the University and um, we were, you know, roleplaying, and she thinks that pump is inflating her with more and more air, and I gotta admit, we were having fun with that for a while, but after you took it last night she started freaking out and saying that every time you used the air pump on the bikes that it was blowing her up with too much air and if you didn't bring it back she was afraid she was going to pop. And I know that sounds crazy, but I think if you just hand me the pump and let me talk her down, she'll finally get some sleep and probably wake up later tonight and be okay once whatever it was she got a pipeful of wears off.”

“That is the dumbest story I have ever heard,” Val said, fixing me with a steely look, “But then, Colette's just a big enough airhead that I can actually kind of believe that that's just the kind of weird, stupid thing she'd get herself into.”

“Really?” I asked, sounding a bit more surprised that I meant to, “I mean, so you're not mad? She's really been having a rough time this morning.”

“You know,” Val said, apparently mollified, “It's actually kind of funny. This pump is a piece of garbage. I had to spend like, half an hour just on one tire after I had a blowout. It's like all the air just leaks out into somewhere else. One of the engineering guys gave it a look and thought it was a bad seal, like maybe the handle wasn't seating all the way down, but a couple of zip ties didn't do anything to help either; it just kept getting harder and harder to push the plunger down. Honestly, it's a good thing you two are using it for whatever weird, perverted stuff you're doing in there; it's worthless for any real work.”

“So, um, does that mean I can have it back?” I asked, sensing that this was as close as I was going to get to catching Val in a good mood here.

“Ha, sure,” Val said as she hefted the pump and held it towards me, “You know, I'm never going to let either one of you weirdoes live this one down.”

“Heh, yeah, I know; Colette's does have some weird turn-ons sometimes,” I agreed nervously, hoping we could get this done quickly.

“Actually, I'm sorry, but I can't just walk away without seeing this,” Val decided, tightening he grip on the pump, “If she's high as a kite and flipping out because she thinks she's an overinflated balloon, I just- I just can't pass this one up.”

“But, um, you don't want to go in there,” I said, trying to get between Val and the bedroom door, “She's really strung out right now, and, um, she's naked, so you can always just come back tomorrow when she's feeling better and have a good laugh then, right?

“Naked? Please,” Val said dismissively, “You don't think I've seen her naked before? We're roommates; I've seen her in the shower tons of times.”

“But, she's uh, she's really messed up now too,” I added, increasingly despairingly.

“Oh, you don't think I've seen her high before?” Val retorted with a smile, “Didn't she ever tell you about that camping trip we went on freshmen year? Oh, Colette and me both have plenty of experience high and naked together. Now then, I'm just going to come in and laugh at my ridiculous roommate, and then I'll leave you two alone to finish doing, whatever it is you do; I really don't want to know that much.”

And without waiting for an answer, Val pushed past me and into Colette's room.

“Okay, Colette, before I go I just have to see what you-” Val began as she barged in, “Sweet. Merciful. Crap.”

“Oh, uh, hi Val,” Colette said, smiling and managing a small wave as she looked up from where she rested atop her enormously endowed figure, “So, I guess I've got some explaining to do, huh?”

“Wait, what did you do to yourself?” Val asked, stumbling forwards as if dazed by the sight of Colette's prodigiously pneumatic form, “How long have you been doing this? I always thought you guys were just up here pretending.”

“Well, actually that's how it has been until last night,” Colette explained patiently, while looking as composed as possible for a woman in her position, “That pump is what we were finally able to use to actually fill me up with air.”

“What, this thing?” Val asked, brandishing the pump at Colette, who swelled up slightly just from having it so close again, “I don't get it; it doesn't even work.”

“Well, not for bike tires anyway,” Colette said with a wink, “But all that air has definitely been going somewhere.”

“So as this time I've actually been inflating you?” Val asked, clearly overwhelmed by the situation, “So what do you do after this; is it permanent?”

“Well, I don't think it's really permanent,” Colette admitted with a shrug that set her wobbling all over, “But I'm pretty sure it isn't exactly going to wear of overnight either. Either way though, would you mind just giving us the pump so we can get back to, you know-”

“This is crazy, just look at you,” Val said, still not handing it over and moving dazedly closer to where Colette lay, “I mean, how does this even work? You're just so, so-”

“Huge?” Colette suggested.

“Um, this is gonna sound weird,” Val stammered, “but uh, can I touch you?”

“Mmm, you can touch all you like,” Colette answered, a lascivious smile on her face, “There's more than enough of me to go around now.”

Val closed in near one of Colette's bloated breasts, which again bulged slightly from having the pump brought even closer, and with her free hand gingerly reached out and touched her fingertips to the faintly throbbing expanse of flesh in front of her.

“Whoa, you're still all soft,” Val exclaimed, jerking her hand away in surprise, “I thought you'd feel hard as a rock with that much air inside you.”

“Oh no, I'm still all soft and supple all over, and so very, very sensitive,” Colette purred, “But you don't need to take my word for it, not if you're curious...”

“Um, I think I should really be going,” Val said, blushing as she turned away from her inflated friend, “This is really more than I'm ready for right now and I should let you two get back to whatever it was you were in the middle of when I came in and I should really be going now, I think.”

“Okay Val, but any time you feel like exploring a bit more, I'd be all too willing to oblige,” Colette called liltingly after her as Val hurried out of the room, dropping the pump on her way out and closing the door tightly behind her, her footsteps coming quickly as she raced down the stairs outside, “Sorry about that hon, I just couldn't resist having a bit of fun with her.”

“So did you really just try to seduce Val right with me in the room?” I asked, not sure whether to feel betrayed or just turned on at the thought of the two girls going at it right there in front of me.

“What, like you wouldn't get off on watching me and her fucking right now?” Colette suggested, “Besides, you saw how interested she was. I think she'd look amazing if she let you pump her up to about ten times her size. Don't even try to tell me you wouldn't like watching that toned ass of hers just blow up like a balloon; she'd probably lose all control of herself before she even popped the stitches on her bike shorts.”

“Well, do you want me to go after her then?” I asked, finding myself more and more interested in getting Val on board with Colette's unusual tastes.

“Mmm, maybe later,” Colette decided after a moment's pause, “Right now I think you and I were in the middle of something right before we were interrupted. How's the pump?”

“Oh, right, the pump, “I echoed, trying to banish the image of Colette and Val both inflated to positively obscene dimensions and going after each other with complete abandon, “Here it is; I think it's- oh, this might be bad.”

I help the pump up for Colette's inspection, but even a glance showed what Val had done in her attempts to fix it. Two bright plastic zip ties had been put around the handle to keep it from going in all the way, and if it hadn't been much good at filling up bike tires, Val certainly hadn't given up easily. The body of the pump bulged outward alarmingly, the sheer amount of air pent up inside it straining the steel just to hold it in. I was actually kind of hesitant to hold it; looking for all the world as if one more push of the handle might make it go off like a pipe bomb.

“Oh my. Do you have any idea how much air there must be in that thing?” Colette said, astonished, “How did she even manage to keep pushing the handle down with the pressure built up like that?”

“Okay, don't worry,” I tried to reassure her, “We'll just put it away somewhere where no one is going to mess with it and set it off. Maybe the air will just leak out of it over time. At the very least, it'll be safer to handle once you're not so, you know, full as you are right now.”

“What are you even talking about?” Colette said playfully, “You're going to cut those ties off and push the handle down right now.”

“Really?” I asked, afraid of what would happen if I gave into Colette's desires, but already entranced by the idea, “Aren't you worried about what will happen if we fill you up with that much air all at once?”

“What?” Colette asked with a pout, as if I was intent on ruining her fun, “Don't you remember me saying how much it turned me on to think of you inflating me until I couldn't even move? Or how I've fantasized about having my tits so spectacularly overinflated that I feel like I'm ready to burst? Or how excited you were last night at the thought of pumping me up until I was absolutely helpless and begging for mercy? Come on, don't back out on me now.”

“You're sure you can take all this?” I asked, though I was already getting out of my pants, “I mean, it's all going to be coming at once; you won't be able to tell me to stop once I push it in that last inch.”

“Oh, but that's the part that really makes me so horny I can hardly stand it,” Colette enthused, her voice fairly dripping with lust, “as long as you're just pumping me up one push at a time, I can always decide I've had enough and know things won't get too out of control. This though, it's going to be like throwing open the floodgates. And I won't be able to say no. Just imagine my tits being forced to hold twice as much in the space of a few seconds; they'll be stretched to the absolute limit! Don't get me wrong, I'm sure it'll be a little bit, uncomfortable, it might even hurt, but I'm just so sensitive all over now, every bit of it will just make me come harder. Just the idea of so much air rushing into my body, unable to stop it even if I'm afraid to take any more, oh no, we are doing this.”

“Okay then, so how do you want to do this?” I asked, finding some scissors in Colette's nightstand and, carefully keeping them as far away from her bloated figure as possible, working at getting the ties off the pump, my hands trembling a little at the thought of what was going to come next.

“Oh, I've got that all figured out,” Colette said assuredly, as if she could already see herself inflated to twice her current size, “I want you to put it in my mouth before you push it down.”

“In your mouth, why?” I asked as the first tie snapped off, “You know this thing doesn't work that way.”

“I know, but that's how I always imagined it working,” Colette conceded, “I've always been so turned on by the idea of taking the air hose between my lips and just feeling it all rush into me at once like that, blowing me up bigger and bigger until I just didn't have the strength to hold on any more. Even if it doesn't make a difference; just do it for me, okay? I promise you'll enjoy the results almost as much as I will.”

“Alright, as long as you're sure about this,” I agreed, handing the end of the hose to Colette, “Just tell me when you’re ready.”

“Oh, I'm ready, and oh so willing. Now, playtime's over; make me really big,” Colette said, smiling broadly as she popped the hose into her mouth and held it there tightly.

There was nothing else to say. I pushed the handle down.

I don't know whether Colette having the hose in her mouth made the difference, or just the fact that we had managed to break just about every rule that the pump had come with, but it actually worked exactly like she was hoping. Colette's cheeks puffed out in an instant as the staggering pressure contained within the pump surged into her waiting body. The strength of the initial rush enlarged her breasts each by another twelve inches, knocking me off my feet as they creaked in protest at being so violently inflated. As they expanded beneath her, Colette rose several inches closer to the ceiling, while the hose, no longer long enough to reach from her lips to the floor, pulled the pump up with it, now dangling freely in her cleavage. Her belly too, was instantly inflated with enough air to make it swell out nearly another foot to either side of her body. Her breasts pushed outwards in front of her as it crowded them from below, while I heard the smack of her soft thighs against its underside as its lush lower curve pushing them out of the way. Though it seemed like most of the initial burst spent its power elsewhere in her anatomy, Colette received plenty all the same behind, her ass billowing into even greater jiggliness, so round and full now that the light above her reflected of it almost like a balloon, while her legs were quickly plumped up to the point where even if they had been able to reach the floor, their extreme voluptuousness still would make them useless for anything other than pleasure.

I expected it to end then; every time we had done this before the pump had delivered its charge into Colette's waiting figure and been finished in seconds. I could see that Colette was surprised as well, as her face rose past eye level for me while her bosom showed no inclination to stop expanding. The look of sheer bliss she had worn at first had given way to doubt, as the amount of air flowing into her seemed to have already exceeded what she had been ready for. All the same she held the hose firmly between her lips, moaning softly all the while.

Each one of Colette's breasts was fully six feet wide now, and growing larger by the moment, their rate of inflation barely slowing. It was obvious that there wasn't enough room for both her overfilled melons and her immense belly, and as a result Colette's breasts pushed more and more insistently against each other, her cleavage expanding out spectacularly before her face, while as her breasts spread further outwards her nipples, no longer buried under her bust, popped into view. Each one was every bit as large as Colette's fist now, and throbbing with unquenched arousal. Colette's areolae bulged out alarmingly from her breasts, as if the tremendous volume of air inside of her was taking advantage of their softness by stretching their tender skin to even greater extremes. Colette's belly continued to grow; there was simply too much pouring into her for her breasts to take it all. Any hopes Colette might have had of being able to stand up after this were surely gone now; there was entirely too much in front of her for her to ever keep her feet without her globelike belly tipping her backwards.

As the air continued to flow, I saw the look of doubt on Colette's face give way to distress. However much she had wanted this, she realized that this was too much, even for her. Her breasts were spectacularly overfilled, swollen well beyond even her wildest fantasies, and from the look of them, well beyond their capacity. They groaned louder and deeper than before at the sheer volume of air Colette was forcing them to contain, each one already so supremely overstretched I was almost afraid to touch her tightly-drawn skin. As the air continued to flow, Colette, lips still tight around the hose, closed her eyes, as if willing herself to endure all this. Her entire body quivered with overfullness, and no matter what she had said about wanting to take herself to the absolute limit, I felt certain that if she could only see how staggeringly overinflated her quaking zeppelins had become that Colette would be afraid to let this last even a moment longer. She seemed too lost in the throes of her own passion to notice just how dire her situation had become, though, kicking her plump legs feebly against the underside of her massive belly and stroking the taut flesh of her breasts insatiably. She whimpered with pleasure, clearly more intent on exciting her own lust to the very peak of what her body could endure than on how desperately overstretched she had let herself become. I knew what I had to do.

The pump still hung between her overwhelmingly distended breasts, and I reached for it, having decided that no matter what Colette might want, I couldn't let her do this to herself. Her breasts had ballooned to the point where they took up the entire center of the room, and only Colette's weight kept them from rising up to the high ceiling. Tantalizingly engorged with air, they inched out wider and wider, every second I delayed lading them even further beyond their limits. I grabbed the pump, tugged it free from the tight embrace of Colette's cleavage, and was ready to pull it free from her mouth when she opened her eyes and fixed me with a look. I can barely describe the feeling she mutely conveyed to me, as look of desperation, of pleading, begging me to save her from her own unrestrained desires, but just as I made ready to pull the hose free from her mouth, she shook her head, and grasped the hose firmly, fighting to bend her arms enough to get ahold of it. What could I do? I had to let her finish this.

I realized now that the creaking sound of Colette's expansion had stopped, the only sounds I could here were the rushing of air and her inarticulate murmurs of bliss. It seemed as if her body had given up any pretense of resisting, as if her overfilled figure had now simply surrendered to her wishes. The pump's long, unceasing breath filled her breasts like a pair of balloons inflated sorely beyond what they were made for, forcing them to spread wider and wider, her huge tits now pushed apart at an angle that looked positively painful, her nipples growing absolutely rigid as they rubbed against the floor. Colette's entire body trembled now; her breasts so huge now that I could hardly even see her face. Her belly had become so enormous that even without her tremendous bosom, it would be more than ample to support her body, while her ass quaked from the pressure, billowing even wider than Colette's broad hips. I couldn't imagine how she could take any more of this; whatever she was feeling, it had her shuddering and moaning in a way that made her entire body wobble with a violence that she was ill-equipped to endure. I was sure she was about to pop; there was just no way that Colette could hope to hold so much air inside of herself, when at last the flow of air into her began to flag.

The rush of air faded from a gale to a whisper as the pump's charge was finally spent. Colette's breasts slowly stopped expanding, their smooth and utterly distended curves still pulsing faintly even as the pump grew silent. Her moans of pleasure grew more faint, and finally she opened her eyes, and smiled as she pulled the limp hose from her lips. It came free silently; she had milked it of every last breath it had to give her. It clunked to the floor as Colette let it drop, and I looked up at her, her round face crowded on both sides by her gigantic breasts.

“Oh- oh that was so much more than I was expecting,” she sighed, caressing her immense bosom expectantly, “I can't believe I was able to take it all.”

“Are you okay?” I asked.

“Okay? I feel like if you give me one more push of the handle there I'll pop,” Colette said huskily, “I never imagined I could feel so- so full, every inch of my body is just tingling. My nipples feel like they must be as big as cantaloupes by now.”

“Just about,” I said, looking down at where her two turgid peaks rubbed insistently against the carpet, “Are you feeling alright?”

“Other than being so horny I can't stand it, I feel amazing,” Colette said breathlessly, “Come on, touch me, I want you to play with my big, overfilled titties.”

“Are you sure?” I asked doubtfully, “They just look so, tight, I'm almost afraid to.”

“No, please, I need it,” Colette begged, “I'm so tight, so turned on, I feel like I'll explode if you don't come and give me a feel.”

I reached out and tenderly placed my palm against her breast. I couldn't begin to imagine how much air even one of her boobs had to be holding by now, her skin stretched impossibly smooth and still, despite the sheer volume straining within her, yielding readily to my touch, as if her body was just as unable to resist me as it had been to resist her forcible overfilling. Despite my worries, concerns for how safe it was for Colette to be in such a dangerously overinflated condition, I felt myself getting more and more turned on by the sight of my girlfriend lying there atop her mountainous tits, expanded into almost complete immobility and utterly bewitched by it. My concerns quickly melted away, my caresses swiftly grew more ardent as I soon pressed my own body eagerly against hers, and Colette rewarded my efforts with ever more enthusiastic sounds of pleasure. I felt her skin growing warmer at my touch; a rosy flush of desire blossomed out from her swollen nipples and spread across the expanse of pale and welcoming flesh in front of me.

“Oh yes, you're so hard, I'm cumming already,” Colette sighed, her breasts quaking as she writhed eagerly atop them, “Come on, before you climb up and fuck me, give me a pinch. I'm so hot I can't stand it; please grab one of my big, fat nipples and give me a squeeze!”

I had long since realized that despite her state, Colette was the one in control here; I bent down and gingerly grasped one of her throbbing nipples with both hands. She gasped, shuddering; even the slightest touch was very nearly too much for her right now. I waited half a beat, and then squeezed as hard as I could, clamping her ruby red peak between my hands like a vise. The sheer amount of pressure inside her must have been incredible; unlike the giving flesh of her breasts, Colette's nipple was as firm as a basketball pumped up to the point of bursting, and felt painfully tight as I tried to compress it.

Colette screamed. Wordless ecstasy poured from her lips, her entire body creaking dangerously as she pawed lustfully at her titanic breasts while her legs kicked frantically against the underside of her hugely bloated belly. The instant she cried out I had let go of her nipple, and yet still she screamed, moaning, almost crying at times for what felt like an eternity, her mind being savaged by a kind of bliss that few women but she had ever dreamed of and none, ever her, were even remotely prepared to withstand. At last the subsiding flood permitted her to breathe, her body still quivering as she panted for enough breath to speak.

Oh- oh, I need you right now,” Colette managed, her breath coming in shallow, ragged gasps, “I'm so hot I feel like I'm about to explode; you have to fuck me, now.”

Colette gazed down at me with a lust-mad passion in her eyes. I knew we shouldn't, that she had already had far too much; that the last thing I should do was to put her through any more than she had already endured. If just a squeeze was enough to leave her speechless, what would sex do to her?

“Please, it's too much for me to take,” Colette begged, and it did look as if she was still expanding, as if her state of sheer arousal was somehow inflating her even more, “I need you inside me! Stop worrying about being gentle and come fuck me like you mean it!”

More than eager to please her, I climbed on top of Colette's swollen figure, her breathless moans of desire and my own growing excitement making me motions less thoughtful than I might have hoped. With my weight added to her own, her massive breasts bulged out spectacularly in front of her, a vista of taut, quivering flesh that spilled out fully six feet in front of her face. Her belly bulged out desperately wide as it struggled to bear the extra weight, and from the way Colette squirmed and whimpered, it was clear that all that extra pressure was squeezing against her inmost depths unbearably. I got myself into position, Colette's titanically jigglesome ass beneath me, my hands holding tight at the point where her belly ended and her lush hips flared out so seductively. She was so huge I doubted for a moment whether this would even work; I was harder than I'd ever been in my life, but Colette was just inflated to such monstrous proportions that I worried I'd be able to get far enough to provide her the satisfaction she begged for.

“Now- I need you now!” Colette urged me, clutching feverishly at wobbling globes, and spreading her impossibly voluptuous thighs as far as her limited range of motion permitted, “Stop dicking around back there and fuck me! My tits are about to- Oooh!”

I plunged into her. Colette's femininity had been filled to the point where I was amazed her body even had room for me. Her labia had been pumped up obscenely, and even the slightest touch was far more than enough to bring her to climax now. The slick, hot walls of her inner body squeezed inwards against me as if she resented me unsheathing myself from her by even an inch, but as she screamed and writhed beneath me, I gave her exactly what she had demanded. She responded in kind, bucking her hips against me, as if urging me to force my way deeper and deeper into her. The most desperately swollen parts of her anatomy creaked distressingly as Colette's body bounced and jerked with her every motion, but even I was beyond worry now, struggling to keep this up as long as I could. I felt like I could give in at any second; I had never imagined how erotic the sight of Colette, naked, huge, and splayed out beneath me, would be, or the heights of pleasure that her overfilled womanhood brought me. Still, I fought for control; she had been waiting for this all her life, and I was determined not to disappoint.

Far from stopping her further expansion, sex only seemed to be adding to it, as if Colette's lust had reached such a peak that even the air around us was able to penetrate her body. Her cries of excruciating ecstasy echoing off the walls, her breasts expanded inch by inch, as if my every thrust was forcing them to grow more swollen. Colette was beyond worry; she lifted her hips towards me and rocked them back to meet my every advance, desperate to take me in as far as she could endure. Consumed and convulsed by bliss, Colette's entire body quaked helplessly, her nipples smacking loudly against the floor with every undulation. I felt like I had to give in; I had already held back so long I wondered just how much more I would pump into her when I let go, and I was afraid if she kept expanding like this she would either explode or leave me pinned between her immense ass and the bedroom ceiling. Every second she writhed and screamed as if she was losing her mind, and finally I could resist no longer. Colette shuddered voicelessly as I erupted inside her, no longer able to even cry out as I pumped and pumped it into her.

Finally I collapsed, utterly spent, on top of her, while Colette, her breath coming in shallow little gasps, seemed to be struggling back to some semblance on consciousness. We both lay there for what felt like a small eternity, exhausted atop her still quivering voluptuousness. She was the first to speak.

“Oh my- I just- Ohh, that was incredible,” she breathed, “I can't even tell you how many times I came; I felt like you were going to keep hammering away until I exploded.”

“Are you okay?” I asked, for what felt like the hundredth time in the last couple of days, “You're so much bigger now.”

“Oh, don't even think about that,” Colette admonished me, “I have literally never felt better. How did you like me?”

“I- I guess I just never really thought about how sex would be with you like this,” I admitted, “I mean, I knew you were going to be blown up all over, but I never really thought about what that would mean for your, I mean, just, wow.”

“Mmm, so you like how awfully tight I am now then?” Colette asked playfully, “I can't even tell you how incredible sex is now that I'm so huge. If I didn't already feel ready to pop I'd be awfully tempted to have you pump me up even more; I can only imagine how amazing it would feel to have you fuck me while I'm even bigger.”

“You can't be serious,” I said, stunned that Colette was still thinking of inflating herself further, “You were complaining about being too full even before your boobs were big enough to fill up your bedroom; do you really think they'll hold much more?”

“Come on over here where I can see you,” Colette suggested, “It's just so distracting trying to talk knowing that any minute you could decide you're up for another round and just spear me from behind again.”

“Sorry, I forgot how tender you probably are right now,” I admitted, “Here, let me get down and-”

“I didn't say I wanted you off me,” Colette said playfully, “I just want a little face to face time. I've got tits as big as zeppelins sticking out in front of me here; it seems such a shame to let them go to waste...”

Colette's breasts creaked faintly as I climbed out on top of them to face her. Still not convinced that she was out of danger, I tried to move as gently as possible, though Colette seemed to have no such reservations, stretching out her plump arms to caress her overstretched flesh longingly.

“There, isn't that better? And don't be afraid to have a feel or two while you're up here,” Colette offered, her face once again level with my waist, “And don't be so worried; I know you're afraid my big, bloated tits are going to burst if you so much as look at them the wrong way, but I feel like I've broken through to a whole new state of being here.”

“What do you mean?” I asked, finding it impossible to resist stroking the supple skin of Colette's mammoth bosom, “Are you sure you're feeling okay?”

“Oh, but I've never been more sure of anything in my life,” She breathed, “It's just that all this time I've felt myself getting fuller as you blew me up, my poor tits just getting tighter and tighter the more air you pumped into me, but just now, while you were just giving it to me, and I felt myself still getting bigger, it's like something inside of me just snapped. Don't get me wrong, I still feel so tantalizingly overfilled that all it takes is a deep breath to make me come again, but it's like now I feel like you could fill me with twice as much and I'd just be able to take it all somehow.”

“How about we wait until tomorrow at least, before we put that to the test?” I suggested, still not convinced that Colette wasn't just hungry for more, even as I thought about how hot it would be to see her swelling up with even more air.

“Mmm, but doesn't the thought of that turn you on?” Colette asked invitingly, her current perspective giving her an excellent view of just how I was responding, “Can't you just hear my tits stretching as you pumped them up with more, or me just begging for you not to stop, even with me all splayed out helpless on top of my huge belly like this? I know you think I've already had way too much, but just imagine how exciting every push of the handle would be, the pressure inside of me growing just a little each time, building and building until I'd just be coming over and over, even without you laying a finger on me. I know you'd be afraid to keep going eventually; the sight of me quivering and screaming with pleasure every time you pushed the handle in would be too much for you to continue just using me like that. But still, you wouldn't be able to resist. Even with my tits so distended you'd be afraid to even touch me, the sight of me so horny that I was ready to lose my mind would be more than you could resist. You'd have to climb up and mount me, with barely enough room between my ass and the ceiling for you to squeeze in, and you'd just fuck me as hard as you dared, and even just running on instinct, I'd do my best to make you give it to me hard, no matter how overinflated I was. And then I'd be aching and overstretched the next day; I'd ask you why you had to go and be so rough with me when clearly I was already way too full for my own good and obviously in no condition to tell say no to anything, no matter how sore it left me. And then I'd ask for just a little bit more.”

“You know you really make it hard to say no,” I confessed, fighting to resist just grabbing the pump and giving Colette exactly what she was asking for, despite how utterly distended she already was.

“Mmm, I do try to make it hard,” Colette smiled, reaching out with one plump arm and stroking me invitingly, “Are you sure there isn't anything I can do to make you reconsider?”

“Um, no, not right now,” I stammered, feeling myself growing painfully hard at her touch, “Maybe- maybe tomorrow, if you still want to get bigger, I mean.”

“Well, if you're just determined to make me wait for that,” Colette breathed, her lips seductively plump as she wrapped her fingers tightly around me and tugged, “Having that air hose in my mouth seems to have left me with just a bit of an oral fixation. Why don't you come a little closer and find out how it feels to get sucked off by a girl while you're laying back on her own tits, and then we'll see if you feel like I could take a little bit more tonight?”
