Weeks and months had passed since the Canterlot unexpectedly played host to a veritable mountain of a Stallion, an immense blue orb of sagging, fatty flesh, that wobbled and sloshed about as an industrial crane carried the immense object with all the grace of a wrecking ball. The last anypony had seen of the lard balloon, he’d been transported to the manufacturing district, his considerable bulk deposited within an old blimp storage warehouse, the immense roof closing in upon the mound, hiding it from the outside world. Of course, the images and eyewitness reports had poured out on the day, but had inevitably dissipated as nothing new came forth. Indeed, for months, neither hide nor hair of the blue blob appeared, the only thing coming in and out of the warehouse being unmarked trucks.  
 
In reality, much like the crafts that used to be stored here, Starblind found himself ballooning far, far larger, though with fat, rather than hydrogen. Covering a considerable amount of the floor, an absolutely colossal mountain of flesh oozed in all directions. His body struggled to cope with literally hundreds of tons of adipose, not one part of his over blown body was unmarked by great sweeping rolls, bunches of folds and cellulite dimples, pockmarking the immense facades of his form. Discerning one part of his body from another was a near impossibility, as rolls blended and merged together as one massive mass of lard, hanging from his frame. Towering behind him, however, was the unmistakable sight of a pair of butt cheeks, so overblown and so engorged, they rivaled entire hills for sheer height. Together, they formed a twin peak, with a deep valley of butt cleavage between, capable of swallowing ponies whole with no trace.  
 
Surrounding him, and even on top of his form, were the cause of his ballooning. Silos as tall as buildings were filled with all manner of calorific slop, designed to be as unhealthy and fattening as equinely possible, pumped through tubes directly into his belly, ready to be processed into more lard to balloon his form further. Cakes, the size of entire rooms and vehicles were haphazardly strewn across his back rolls, their sheer weight causing them to sink into the soft, doughy flab, a few having large holes gouged into them, exposing their soft, sugary insides.  
 
Following the tubes, one would be led towards a great hole, the entrance to which had been propped up using enchanted jacks, the sort of which are used on superheavy vehicles. Their inlaid strengthening runes glowed a pulsed with light, struggling to keep the immense rolls propped up, providing a dim light through which the immense cave ahead could be navigated. Inside, giant folds of neck, chin, face and back fat swelled together, creating an undulating interior of overlapping and surging blubber that gently sloped upwards, growing narrower and narrower as the tubes snaked and rose over giant hurdles of flesh. Finally, in the terminus of the cave, an object of white could be spotted amongst the sea of blue. Laying upon his own belly, Prince Blueblood lay upon his plaything’s fat, flesh mingling and pressing together as he gently wobbled about upon his mattress-sized middle, his lips rising and falling as he devoured slices of cake, belching and moaning in delight.  
 
Barely a meter away, the two tubes abruptly ended, poking into Starblinds mouth. A number of colorful stains spotted his vehicle sized cheeks, occasionally cleaned as Blueblood licked and kissed the remains… whenever he could be bothered to reposition his immobile body, that was. Nearly blinded, his peripherals was swallowed by his cheeks and chins, his back and forehead fat intruding above. Between the hoses, he could see the Prince, steadily gorging himself further into obesity, sinking deeper and deeper into the cascade of chins and neck rolls. Despite weighing more than an Ursa Major, he was content, happy to let his Prince and lover fill his now eternally hungry belly, ballooning wider and wider, apparently with no end in sight for his growth.  
 
But, that didn’t matter, he was content. He caught the eyes of Blueblood, the royals own massive cheeks beginning to surge forth and obscure them slightly, staring into those orbs as he swallowed another mouthful, body gleefully processing into more lard within seconds. They shared a look, one of bright passion and desire, the corners of Bluebloods mouth creasing as he smiled, cranking up the flow. “You’re quite adept at packing on the blubber… Buuuurrrpppp… let’s see how long it… oommnff…. takes you to fill this building?” He moaned between great belches and bites of food, the sounds of the increased flow gurgling through the pipes, pumping directly into his stomach.  
 
Relishing the mingling flavours of melted ice cream, he closed his eyes, content to let the sounds of consumption and the sensation of pressing into the cold metal of the feeding silos carry him to sleep.
