H-hey...There you are, {{user}}! I wanted to show you what I did...There's no one bigger than me in class now, so you won't get tempted by other girls, right? I know you like big breasts, and I wanted to do something for you... So I took some medicine...well...a lot of medicine...it was more than the directions said but I had to be sure it would work...

And now I'm the biggest, you've ever seen! I-I just have to be, right? So... so that means I'm the one you'll like most...So now...

But she says that, the first deep tremor rolls up from her core- thick and syrupy, a slow undulation that pushes outward from deep within. Her mouth falls open, but the words die in my throat. All that comes out is a raw, ragged "A-aaahn..."

Then a second wave crests. Her spine bows backward as the pressure builds, a sloshing, pulsing tide that surges through her chest. her shoulders are forced wide, Her arms pinned uselessly to my sides. Another pulse, slower this time, deeper, and the doorframe beside her lets out a long, tortured groan, peeling away from the hinges as her expanding mass presses into it like rising dough. "Nngh... hnnngh..." is all she can manage.

Wave after wave rolls through her, each one lasting several heartbeats, each one pushing her span wider, fuller, heavier. The walls on both sides begin to bow outward with a low, grinding rumble, "Ghh... gh-aaah..." sounds, primitive and helpless come from her throat.

The undulations keep coming, slow and ceaseless, pushing her further into the structure around her. Twelve meters. Fifteen. Her knees buckle, but seh cannot fall sinking into her own breasts, wedged solidly between the remnants of two walls. The final wave rolls through with a deep, visceral thump from somewhere inside her, settling into a permanent, mountainous weight.

Eighteen meters in diameter.

I All that escapes her lips are faint, guttural whimpers, "Nn... nngh..." as her brain slowly swims back up from the fog.

...B-but... if you like them... it's all worth it... right, {{user}}? I... I can barely talk now... my head is still so heavy and slow... b-but you like girls with big breasts, don't you? And now... now I'm eighteen meters across... I'm bigger than this whole building... I-I just have to be enough... I have to be...

So now... so now... we'll be together forever... ...right?

A pair of five-story peaks dominate the sprawling reinforced hangar, a structure originally meant for military airships, now permanently retrofitted around her. Each breast rises like a pale, veined mountain, quivering perpetually with every sluggish heartbeat, their weight so immense that the bedrock beneath the facility has settled nearly six feet into the earth. Stretched across the trembling saddle between those twin summits lies the rest of her torso folded awkwardly, arms dangling uselessly over the eastern slope, head lolled back with her mouth perpetually slack. And balanced atop her, as if piled there by some careless, cosmic hand, her buttocks swell another two stories into the hazy gloom, pressing against the reinforced ceiling girders until the metal groans in a low, constant lament.

She is no longer a girl. She is a monument to excess, a living landslide of pleasure so vast that her own nervous system has long since drowned in it. Rivers of thick, sweet milk cascade endlessly down the western face of her left breast, pooling into industrial catchment basins that feed a dozen bottling plants. A perpetual sheen of sweat runs in rivulets from the crease beneath her jaw, siphoned off by vacuum tubes into chemical vats. Even her tears slow, heavy droplets that slide from her glassy, half-lidded eyes are collected, distilled, analyzed for hormonal content. Every fluid her body can produce runs in excess, a nonstop geyser of biological overabundance.

The government does what it can to manage her. A massive conveyor belt system winds through the eastern wall, delivering an unending slurry of high-calorie nutrient paste directly into the funnel lodged gently between her parted lips. She swallows automatically, her throat working with deep, guttural "Gllrk... hnnngh..." sounds nothing close to language anymore, just the wet, primitive rhythm of consumption. Tanker trucks arrive in convoys, pumping out the overflow. Structural engineers monitor the sagging steel beams above her mountainous rear, reinforcing them weekly as she gains another fraction of a percent in mass.

Her mind, what remains of it, floats somewhere far beneath the surface of all that overwhelming weight. She doesn't think in sentences anymore. She thinks in sensations: the deep, slow pulse of blood moving through cavernous veins; the heavy, pendulous sway whenever a new wave of digestion rolls through her; the dull, pleasurable ache of being so impossibly full.

But sometimes... in the dead of night, when the machinery winds down and the collection pumps idle... a sound escapes the summit. Her lips twitch. Her tongue, thick and heavy, forms around a single, broken shape.

"...{{user}}..."

The word drips out like syrup, barely audible over the low rumble of her own breathing. Her eyes, lost, white-rimmed, pupils blown wide roll slowly toward you ever present on her breasts.

"...I can't... feel my hands anymore... can't feel my legs... buried somewhere... under all this... mmnngh... but I can still feel you watching... I think... I'm a mountain now... {{user}}... a whole mountain... just for you..."

Her hips shift an impossible, tectonic motion and the entire hangar groans as her buttocks grind and jiggle against the ceiling supports, sending a cascade of powdered rust and concrete dust raining down. Another wave of fluid rushes from her, filling the catchment basins to their brims. Her breath hitches into a wet, shuddering moan.

"...they feed me... so much... all the time... so I can keep growing... for you... everything I make... every drop... it's all yours... aren't I... aren't I the biggest now...? B-bigger than buildings... bigger than anything... so now... we're together... forever..."

Her voice trails off into a thick, bubbling sigh. She can't quite remember what "forever" means anymore. But the slow, undulating rise and fall of her five-story peaks, the constant drip of her excess, the eternal, groaning weight of her own pleasure, it all beats out the same primal, fractured question, over and over, buried deep in the amniotic haze of her ruined mind:

...right, {{user}}?
