“I've gotta be close...” Ashley whispered to herself as she muscled her way through the thick brush of the jungle. She had traveled far to find it. All the way across continents, going only on vague clues written in books from centuries before. She hefted herself through a particularly dense section of leaves and branches, getting to the other side, only to hold back onto the branches tight when she happened upon a large clearing. She stared down the cliff, a circular pit encompassing a stone dome, about half a mile down in the ground. Ashley looked upwards, seeing that the forest had become quite thick above her.

“No wonder I couldn't see it when we flew over...” She muttered to herself, recounting the long and tedious journey to get to this point. Years of research had led up to this. She looked down, a look of awe and excitement on her face, but still proceeded with caution, using the branches and roots of trees to her advantage as she scaled her way down to the stone dome. It seemed to be as large as an entire gymnasium. Handling herself quite well, Ashley was a stocky and big-boned woman, but by no means overweight or obese. She as quite fit, actually, she merely had a thick structure to her. Her long, flowing brown hair was tied in a ponytail and tucked securely under her denim cap. Dirt and mud splattered across her white tank top and khaki shorts, but she paid no mind, as they were easily replaceable and cheap clothes worn specifically for this adventure.

“This is awesome! Haha! Its been so long since I've been able to do something like this...” Continuing her careful yet agile scale down the mountain, her necklace began to glow brighter and brighter as she made her way down. She took little notice to this, needing to focus exclusively on her descent, as to not slip and fall. The necklace held a thin, silvery charm, as long and as thick as her pinky, made of what looked like solid iron, though the material could not be identified. It had strange symbols carved into it, that looked parts Mandarin, parts Arabic and some mysterious third language that she couldn't figure out. It was this very artifact, presented to her by her older brother, that led her on this journey. Her brother couldn't join her, unfortunately, as he had to immediately go after giving her the necklace, being a part of the military and all.

“Almost there...” She finally stepped down onto the stone dome and flopped slowly onto her large rear with a sigh. She sat there, catching her breath, then stood, brushing herself off. Ashley rubbed her thick thighs and wide hips with a sigh; that was where most of her weight resided. She had always wished she could balance out a bit, her DD cups were indeed nice, but were not really all that impressive on her large frame. This imbalance made adventuring hard at times. She shook her head – now was not the time to be thinking of her figure! She needed to find a way into this dome...

Finally, she noticed her necklace, its glow now almost as bright as an average flashlight. She thought for a moment, then pulled out a small notebook from the side of her boobs (it was the best storage she had for this sort of thing). She opened it and took a look at the notes she had written from the various scriptures she had read up on before she had left on her excursion.

“Hmm...so the closer I get to this...'technology'...the more this thing glows...maybe it knows where the door is?” She asked herself as she began step forward hesitantly onto the dome-like surface. Moving ever so carefully as to not fall into any traps or veiled holes, she followed the light of the charm around her neck until she came upon a slight crack in the surface of the stone. A straight line crawled down the surface until it met another that went at a 90 degree angle to it. These two cracks met up with another two and formed a small square indent in the surface of the floor.

“Aha! Gotcha!” Ashley brushed her hands across the small slab, but jumped as it slowly hovered downwards, taking her with it! She held on close as it slowly made its way downwards into the stone building. “Woah...wait a sec...I'm facing the wrong way...!” Ashley cried out to no one as she held on for dear life. Soon her torso was through, but as soon as her ass made it to the opening, it began to wedge and get stuck. “Oh don't you dare...!” She looked behind herself as her hips squished into the stone entrance uncomfortably. “Oof...goddammit, why does my fat ass always cause me issues?!” After a few more moments of very slow gradual movement, her butt managed to dislodge itself from the opening with a dull “pop!”, sending her hurling into the room for a few moments.

“Eep!” Ashley let out a small cry of distress as the stone slab made its way down at a slightly faster pace. It gradually slowed, however, and gently landed on the floor, Ashley finally able to reunite her feet to land. “Well...that was an interesting entrance...” She muttered to herself, getting a look around the room. It was dark. No light except the sparse bit that flickered from the above opening. It wasn't until she took a careful step forward that the lights in the building whirred to life, revealing what lay hidden in the dark.

The room was massive. As long and wide as an entire gymnasium, as she had surmised from the exterior. It seemed to be made of a sort of rusted chrome, everything but the floor beneath her being reflective, but dulled by either age or purpose. The light reflected off this wall and that, making so only one bright orb in the center of the room was necessary to light the whole place. But the most interesting thing of all was what lay in the center of the room:

Three large rings, connected to the floor, spaced out an even distance apart that stretched from one end of the room to the next. At the very end of one of the gates was what resembled a console. Ashley decided that this was her destination now. She stepped over to the large screen-and-hardrive combo. It didn't look like anything man-made. It looked so much more advanced, with strange words scrawled across its surfaces.

It took a moment for Ashley to soak all of this in, but when it did, it really hit her.

“Holy...shit...I hit the fucking JACKPOT!” She did a little dance in place, her large booty jigging in her loose khaki shorts. “When I tell this to the other archeology guys...shit, I'm gonna be in the papers! Wait until they get a load of this!” She whipped out her cell phone from her cleavage and opened it, but noticed something: she had no bars. She stepped over to the opening, but there was still no reception. Stepping back over to the console, she shrugged and started taking pictures of her surroundings. “This is all I'll need for now...” She stepped closer to the console, ready to observe it a bit further.

“Hmm...interesting...wonder how long this sort of thing has been here...it looks practically new...” Ashley observed it a little more, noticing a treadmill sort of flooring leading through the three gates. “I wonder what it does...so strange...” She snickered. “Ah, who cares? This thing is gonna make me RICH! I'll be rolling in it after I get these photos in. It'll be a fucking museum or something...” She looked over at the console, no light emitting from the screen or the buttons. She noticed one big green button that enticed her a bit “Hmm...what could this be...couldn't hurt to press it, probably doesn't have power anyways...” She reached over and pressed the green button softly, awaiting a result, but noticed none. She scoffed. “Ha! Thought s-”

Suddenly, the floor beneath her seemed to lurch forward. “Wha?” Slowly, the room began whir and buzz with life as the conveyor belt beneath her slowly made its way forward. “Uh...wait, woah, what is...” Fences raised around her and created a thin entryway down across the room and towards the gates. She could only watch as she became trapped inside of it, the floor beneath her slowly picking up speed as it moved forward.

“Hold up...what the hell is going on?!” Ashley cried out as she passed through the first gate. She heard a soft “ding” as she continued onwards to the next gate.

It was then that she noticed an odd tingling beginning to spread through her boobs. Her chest became very tight with every breath she made, and her tank top began to clench uncomfortably to her skin. Her bra pinched into her and started to creak audibly with every passing moment. “Wh...what the hell is going on with me...?” She moaned slightly, and clamped her hands over her mouth in shock. Why did she just moan? What was this place doing to her? Why was she so horny right now?!

Looking down only brought her more confusion: her breasts were bigger. Not by any noticeable amount, but Ashley knew her breasts, and they definitely didn't push out of her collar like that before. She tried to inhale in and out, thinking that it might just be an optical illusion, but that only made it worse.

“AHHHHHH!” Ashley finally let out a scream of terror, watching her breasts push out away from her slowly with each moment, gradually becoming E cups, which on her frame were around the diameter of CDs. “This can't be happening! What the fuck is going on with me?! Wh...why...?” The short growth soon came to a halt. “Oh thank goodness...now then...” As she said this, she passed through the second gate, and they jumped back out in renewed vigor. “You son of a-” Her heart sank as she felt her bra continuing to strain, the clasp screaming under the pressure of her engorged tit flesh. “Make it stop...gotta get off this thing...” She looked around, but there was no foreseeable way off – the fences that raised around her were smooth and had no way to be climbed, and went well above her head.

Her breasts had reached F cups and were now the size of ripe melons. They were beginning to slow again. She looked forward in horror: there was still one gate left to go. She turned and began to run, the treadmill picking up speed in response. “Goddammit...just stop! I don't need...my tits...any bigger!” She muttered between breaths. Her large breasts bounced and bobbed with each heavy step forward, but she made little to no progress at all. The treadmill she ran on picked up the pace every second, her breasts bobbing and wiggling inside her tight tank top, smacking against her chin and ribs, back and forth, back and forth in rhythm. There was a soft “snap” inside her shirt, alerting her that her bra had had just about enough of its exercise.

Eventually, she lost her footing and tripped onto the conveyor belt, landing on her now much bigger and softer breasts, zipping right through the last gate. She felt her bosom tingle and wiggle once more, puffing up another inch or so to reach a G cup, just a bit smaller than her head. She panted and heaved, her breasts rising up and down with her labored breaths. “Damn...it...” She cursed under her breath as she took a few more minutes to collect herself, eventually standing on shaky feet. “I gotta get outta here...before any more shit like that happens...”

Making her way over to the small opening in the ceiling, she observed the tile that rested upon the ground. “Now how do I...?” She poked and prodded at the tile, trying to lift it (with little results). She let out a sigh in defeat, which turned into a look of worry. “Oh God...how am I gonna get out of here?” She searched around the room in search of an exit, but to no avail. She sat there a moment, collecting her thoughts, then came up with an idea. Pulling out and reading her notebook, she recalled something she had read before.

“Inserting the key into the machine will bring out the true potential of the technology...” She read out loud, then looked down at her necklace. “Maybe...it can do reversals too?” She muttered hopefully. She shrugged, her breasts jostling around in her top. “Worth a shot.”

Ashley made her way back across the large room, away from the conveyor belt and over to the console. She searched across its surface for anywhere the charm might fit until she came upon a small indent. “Ah!” She pulled off to necklace and slid the charm into the console. After a few seconds of nothing, the machine began to let off various beeps and tones until the screen lit back to life. Several images displayed of strangers she had never met moving at rapid paces, weird videos that looked like cells dividing, white blood cells and other various health and body related things. This went on for a while until the screen finally went dark and just showed an image of Ashley.

“Hey! Is that...?” She asked, not entirely aware of what was happening. A circle then appeared around the picture, specifically around her breasts. Ashley squinted at this, piecing together what it was trying to tell her. “Erm...yes, if you could shrink those down, it would be nice of you...” The machine responded with a loud buzz and a harsh push of air. Ashley stepped away, taken aback by this, and back onto the conveyor belt. Suddenly, a metal rung clamped itself onto one of her feet. “HEY!” Ashley went wide eyed and glared at the clamp, rotating her body out of the uncomfortable position. This only let her other foot become clamped tight.

“SHIT!” She reached down and began prying at the clamps, with no luck. She could barely see past her pendulous jugs as they swung about on her torso. “Come on...make these back to normal...please? I mean, I did kind of want balancing out, but...this is all too sudden, I don't want this now...” She muttered all sorts of thoughts in her panic as she looked back over at the monitor. She tried to read the words on it, but they were in a language she couldn't decipher. It soon flipped to another language. Then another, until finally, it switched over to English.

“HUMAN ENGLISH DETECTED” was written in bold red letters across the monitor. It scrambled up again until another message displayed: “KEY #6 HAS BEEN ACTIVATED. BEGINNING MAMMARY AUGMENTATION VERSION 2.2” Ashley's eyes widened in fear again at these words.

“Augment...? No...NO! That's NOT what I want right now!” The fences rose. The treadmill began to move. The gates whirred to life with various colors as strange symbols rotated across them. “STOOOOP! PLEASE!” The monitor paid no mind to Ashley's cries. She had already made her way through the first gate and her body shuddered under the strange sensations that racked all through her body. It felt like streams of electricity were flowing through her whole body, all flowing towards a common goal: her breasts.

But soon the sensations had ceased. The gate went about half way and then halted, Ashley's feet still clamped down in place. She observed her breasts, dreading what may occur. To her relief, she felt nothing else happening to them and figured something must have failed in the device.

“Whew...that was close. Now then, how the hell do I get these things o-”

*BWOOMPH*

Her left breast suddenly puffed up and inch. Ashley looked down at it in horror and swallowed what little saliva she had left. Seconds later, her right breasts grew along side it an inch, and she had a nice juicy pair of H cups, as large as her own head. “O...ok then...just...don't do anything else ok...?”

*BWOOMPH!*

The left breast then grew by two inches, wiggling and bobbing about in her now tearing tank top. The tingling had returned and was starting to flow throughout her whole body. It wasn't long until her right breast joined in the growth and she had breasts the size of bowling balls. “Unnhh...shit...ok, enough! No more! Plea-AHH!” Another surge of growth flowed in through her left breast, then her right, in succession. They had reached the size of volleyballs and were now pleasantly tingling like crazy. Ashley tried to hold back her hands as well as she could, but couldn't resist. They felt so plump...so...full.

“Wait, why do they feel full?” Ashley asked herself as they pumped up even more, now sloshing about with every movement she made, every breath she took, every jiggle her breasts made. Her nipples were soon erect and poking through her now very thin tank top. The top had been drawn upwards, her belly exposed trying to cover up the increasing tit flesh that decided to peek out from both sides of her shirt. “Oooh...no...please...stop...I'm begging youuunnnHHH!” The biggest growth struck her, her breasts jutting forward half a foot, now the size of nice, perky watermelons, her shirt creaking and tearing to shreds as they made their assault outwards. Her bra fluttered to the ground, now completely useless against her mounting mams.

Ashley raised a tentative hand and brought it to her puffy nipple. It was about the size of her thumb, bright pink against her creamy white skin. She brought it closer and closer...knowing it was probably a bad idea to touch...but she had to...they were screaming to be fondled...to be held...

As soon as her fingers made contact with her nipple, it began spewing milk furiously.

“AGGHHH!” She came on the spot and collapsed to onto her breasts. As soon as they made contact with the rough surface of the conveyor belt below her, her other breast joined in, shooting milk from its nip and sending her orgasm into overdrive. Ashley merely sat there, her large ass pointed towards the air as her even larger breasts poured out pint after pint of milk furiously across the ground below her. “MAKE IT STOOOOOP!”

As she screamed it, the conveyor belt moved once again towards the next gate.

“No...NO! NO MORE! I CAN'T TAKE IT!” She managed to get back into a standing position, her breasts still gushing milk with no signs of stopping. It wasn't until she was through the next gate that changes once again began to occur...

The milk that erupted from her soon turned to a much softer expulsion, then to a slight trickle, until there was nothing more than white stains on her breasts. She stood there and panted as once again the conveyor belt came to a halt midway, the tingles returning into her breasts.

“Please...no more...I'm done...let me off this thing...I won't tell anybody...please...” Soon she heard an audible creak, like plastic or rubber being slowly filled with air. “Wh...what is that sound?” Ashley asked. She looked back at her breasts. They were growing again. This time both in union, very slowly and gradually, millimeters at a time. The sound grew louder and began to echo within the large chamber she was trapped in.

She then felt her breasts begin to rise, getting lighter and lighter, until eventually, they were raising off of her torso.

“Oh God...I'm blowing up like a balloon now! First I was a fucking dairy cow, now this?!” As she yelled out her breasts continued their rapid growth, now bigger than party beach balls, ones you would find at concerts. They were soon knocking into her chin, weightless beyond all belief. The sound of stretching rubber filled her ears as it got closer and closer to her head.

She could feel her feet being lightly tugged at as her whole body felt weightless, her two titanic tits being filled with enough weightless gas that she could gently rise. Her back arched slightly as they became more and more perpendicular in relation to her torso. Ashley had no words left. All she could do was watch as her breasts became more and more bulbous, strained and spherical, getting as large as beanbag chairs, possibly bigger than that.

After a few more moments of pumping, she made her way through the next gate, and the sounds quieted, her breasts returning back to her chest.

“What...*pant*...now...?” Ashley hadn't stopped cumming since she had touched her nipple in what seemed like ages ago. Her whole body was shaking, and the only reason she was upright was because of her weightless tits. Now, they had returned to normal weight and began to feel heavy. And heavier. And heavier. Soon she flopped onto her flesh bags, lolling forward onto them and just caressing their size, grasping at the sensitive flesh as she continued to orgasm relentlessly, the peaks and valleys of her climaxes seeming to have no distance in between. She soon felt herself being lifted, and heard a soft “clink”. The clamps around her legs were released just as her breasts began to make a tremendous leap outwards, the growth spurt being unlike anything she had ever experienced. Her breasts were as large as her, then bigger, and bigger and bigger until they were nearly 8 feet in diameter, and still they grew. She soon found herself at the end of the track, her breasts heavy and engorged, and incredibly sensitive.

She panted and heaved, unable to make any words as her orgasm quieted, spiking a few more times before coming to a halt.

“No more...please...normal...I don't...help...HELLLP...” She cried out, hoping someone would hear her, but knowing it was all for naught...

It was then that she heard footsteps. Soft, delicate footsteps made their way from the other side of the room.

“Hello? Is someone there? Please...help me...” She heard silence in response, the footsteps had ended. Soon after this deafening silence she heard a chuckle, one filled with a sort of coyness she didn't very much like at this point in time.

“You have seemed to have helped yourself enough, dear. I believe you are full to bursting.” It was a man's voice. An old man's voice. Ashley moved her head as well as she could and looked over to her side. Beside one of her large boobs was a strange looking man. He had marks and scrawlings all across his flesh that looked quite similar to the ones on the gates and her old necklace. He was quite tall – but was still dwarfed by her immense masses – and had long, flowing silvery hair that went to the small of his back. It was matted and messy. He wore a black cloak that covered everything but his hands, which were a sickly gray color. They were also riddled with strange growths and abrasions.

“Who...who are you?” Ashley managed to gasp out. The man stepped around to her front so she could get a better look at him.

“My name matters not, for you wouldn't be able to understand it, child.” He rested a hand upon her soft, warm flesh. She cooed in response. “I am the proprietor of this establishment of which you have trespassed.” He stepped back and began to pace along the room. “I suppose you deserve to know where you are...and who I am...”

“Long ago, my people discovered something. A small blue marble far away in the horizon. After a long bit of legislation, we launched an investigation towards it. I was the captain of it, and I piloted the ship. Upon entering the atmosphere of this marble, our ship ceased functions. Several parts broke away, and the console spit out various keys that we needed to function the ship. Many of my crew have passed, and I remain the only one to survive.” He stepped back towards to the console and looked into it, then made his way back over to Ashley. “It seems I am only one key away from returning home. I thank you for bringing it here, child. It has been a millenia since I have seen home.”

He observed her some more, a sort of sad look in his eyes.

“I'm so sorry this had to happen to you. The machine on this ship is highly experimental and was never meant for your species. The fact that it does such abnormal things to your kind is unsettling.”

“What's it...supposed to do then?” The strange man continued to pace around as he explained.

“Well, organic matter itself is not supposed to move through these gates. The clamps are for various carts that we take through them. It is used for genetic alteration...or what is known for your people in mythos: alchemy. But...things went haywire. With every key we get, another woman gets trapped...” The man snapped his fingers and several walls began to slowly rise, revealing, much to Ashley's horror, other women with varying afflictions. A woman with an ass to match Ashley's breasts. Another had a belly that distended far beyond her own legs. Another looked to be at least 12 feet tall. All were held behind glass and had some kind of oxygen masks on as they slept peacefully.

“The means to turn these women back to normal is...not yet understood. The machine does various things to various species and genomes. But you must stay here. We will find a cure for you. All of you.” The man nodded sympathetically and snapped his fingers once again, summoning small robots from out from the walls. They shot mini beams out of themselves and the energy formed around Ashley, lifting her up and leading her to a cage. Her massive expanse of titflesh wobbled and jiggled about as they carried her over to the room next to one of the women.

“Wait...if this isn't supposed to happen...then why didn't you stop the machine the first time it worked on me? How could it grow me the first time if I hadn't yet put in the breast augmentation key?” Ashley asked as she was set into the glass cage. The man did not answer, he merely looked into the glass with a somber look on his face. Ashley donned the oxygen mask and watched as this somber look transformed slowly into a maleficent grin. It was the last thing she saw before she had lost consciousness.

THE END
