Amber woke up under a bright light shining down upon her. Amber was 19 with brown hair and green eyes, she weighed little above the norm for a girl her age with any fat she had concentrated in her butt and D cup boobs. She wore black leggins which exadgerated her ass a tight denim miniskirt and a white tank top which also defined her curves.

Still in a daze Amber tried to move her arms and legs with little success. As her eyes focused in on her left arm she noticed it to be held down by a strange holographic shackle. Upon closer inspection she found this to be the case on her other limbs aswell before extending her gaze and noticing the massive 2 by 4 metre table she was tied to.

with no clear idea about what was going on and a feeling of dread welling up inside her she became flustered.
'Where the hell am I' she said quietly
'An excellent question' said a voice from seemingly nowhere inside the huge blank room.
'Whats going on' Amber asked quickly
'One question at a time please' said the voice 'you are currrently in test room 28C. you have been brought here against your for the purpose of...
'let me out of here' screamed Amber
'im afraid no one can hear you outside these walls. protocol dictates that subjects be kept in a vacuum surrounded test environment to discourage the curious ears of our competitors' the voice
said
'You have no rights to keep me here' shouted amber
'And you have no right to dictate our rights within a facility solely controlled by our coorporation' snarled the voice 'now sit back and relax and maybe you will benefit from this as much as us.'

a tube about 4cm in diametre snaked its way down from the ceiling towards her mouth
'what is that' amber stammered
'this tube is the delivery vessel for a new substance we are working on' said the voice
'wait wha...poompf' the tube entered her mouth prohibiting speech
'the serum is meant to cause instantaneous weight gain as it is absorbed straight into your bodies fat deposits' the voice explained

*hahaha that had to be a joke...right...* thought amber

suddenly the tube jerked. a flow of creamy yellow liquid could be seen coming downwards towards her...then it reached her mouth...a sudden flow of the suprisingly swet liquid went down her throat without the need for Amber to swallow. Amber noticed a pleasent tingling throughout her body...but then something came tight...

She looked down to notice that her butt was expanding followed be her belly and boobs. her already tight denim miniskirt was tightening around her bulging thighs while her belly slowly pushed outwards against her tank top. her breasts were jiggling as the fat was pumped into the bit by bit causing ripples of pure peasure through her body intensifying as she got bigger.

*this isnt happening but why is it so damn hot*

Her butt was growing at quite a pace with her miniskirt squeezing her thighs in by at least 3 inches. the pain she experienced was not horrible but more enjoyable. her belly was now poking out as if she had stuffed herself with a large meal and her breasts had worked their way up to an easy g cup.

Looking down she heard some stretching as the fat in her thighs was still contained by her miniskirt. the pain was now less bearable and her thighs were being compressed by 5 inches on each leg. then finally on the left a large crack as the outer seem gave way sending a wave of fat crashing into the space. the other leg followed shortly with her tattered miniskirt slowly sliding off the table she sat on with only her leggins on her bottom half that were becoming more transparent with every inch put onto her waist.

Her belly was accepting less growth having only just started to sag downwards while her breasts had in 10 minutes worked their way up to a modest double M, looking like two fleshy bowling balls on her upper torso. Her expanding cleveage was causing her tank top to be pulled upwards to cover their increasing bulk.

*oh my god look at my boobs their huge and my thighs must be at least 3 feet wide*

each thigh now was a tree trunk in its own right each nearly 2 feet wide. her ass itself became pronounced on the back pushing her back at least a foot away from the bench. her belly now hung down as 2 rolls began to appear simultaneously stacking on top of each other under her tank top which had now been pulled up most of the way to cover her football sized breasts. even her arms were filling out now each as thick as a 3 litre cola bottle. Her face too began to share the wealth of blubber now surrounding her with her cheeks becoming pro-nounced and a second chin starting to drop down.

after another 20 minutes the flow of liquid tappered off. The hose detatched and the table tipped to a 90 degree angle sending her hulking form crashing onto the floor jiggling as it went. She was now supported by her exercise ball sized breasts which were now fully uncovered having bust through her top and bra simultaneously. her belly however barely touched the floor where as her now titanic ass supported the back. her thighs were 4 ft a peice with her ass protruding miles outwards from her back. her lower legs were near undestinguishable due to the loss of definition around her knees while her arms feet and hands looked like they had been inflated from a gas tank.

the voice crackled into life again 'ah good looks like you completed stage 1 without andy problems'
'what do you mean stage 1' she asked pretending to be frightened but secretly dying to find out
'well you didnt think we would put you in a room this big without a purpose did you' it asked
Amber looked around at the huge room in which she filled only a fraction. the hose above her started to writhe again and make its way towards her mouth. this time she accepted it gleefully anticipating the next stage.
'now we know that yo are a suitable subject we can turn the maching up to 100% output'
Amber wondered what sort of output she was on before. this question was soon answered as the surge of liquid coming faster than she could have imagined. the sudden rush instantly began to fill her already huge form.

her breasts within seconds had blown up from exercise balls to 7ft wide globes on her chest while herbelly began to touch the floor and support her wieght more. her but however still predominuent tore open the leggins as the reached ultra thiness leaving oly her panties un broken. her thighs were reaching their limit now expanding outwards and began to fowards too.

all of a sudden something started feeling tight. her skin was beginning to stretch now. her now limited capacity for growth caused her thighs which were expanding fowards to begin merging with her belly and her legs spread wide as the fat looked for every last peice of stretchable skin. her breasts were now 11ft a peice spreading out like large waterballoons on the floor while her belly expanded at bothe the front and the back.

slowly her body became more spherical. the fat on her back merged with that on her ass leaving a flatter but by no means less curved side to the sphere while her breasts continued to grow out over the floor to a size of 12 feet in diametre before finally pumping up to their maximum volume.

the intense pressure was too much...pain...pleasure...orgasmic sensitivity in her breasts and arousing tightness in her ass...an overload of feeling and emotion...before finally she blacked out, leaving her with only a vague sensation of expanding further...

Amber awoke in her bed, aroused by a breeze flowing through her window across her she looked at herself in the mirror next to her bed noticing that she was back to normal size wearing her pajamas...
'Oh no that was not a dream' she shouted 'THAT WAS NOT JUST A DREAM' pounding her pillow. quickly she recounted what she just saw in the mirror and lept up. how she missed it originally was beyond but her breasts were no longer the D cup they were before but looked more like a G cup now. to make sure she attempted to put on her bra. even with all her might she could not put it on and then staring down she noticed that her ass was larger too. she admired herself in the mirror before shifting her attention more towards what she could wear at her new size.

Whipping open her wardrobe the first thing she noticed was a bright parcel on the shelf in front of her. the tag read 'lots of love from our team and we hope we can do it again sometime' she laughed at the first thought of this but given a second thought if she was asked, she probably would do it again. with that though the note rearranged itself saying
'Response noted, now take a look in side'

tearing apart the parcel she found a device with multiple buttons and dials. another note attached said 'this device will when used properly allow you to alter your physique at will P.S you helped us to perfect this so the first edition goes to you. Smiling amber placed it back in the box
'Not for me thanks, ive had enough of that to last a life time' she said knowing deep down that the little device would come into play again far sooner than she made out...
