The candles had burned low, and Luna's moon hung high in the night sky. But at last it was done! Bright Spark glanced up from his desk, frowned at the clock on the wall of his study, then returned his gaze to the glittering parchment between his hooves. Finally his spell was complete! The spell which all his colleagues at Celestia's School for Gifted Unicorns insisted was 'unnecessary' and 'impractical.' The spell which went against the Royal Sisters' obscure and ridiculous ban on food-conjuration magic. Really, what was the harm? His line of research was practically mundane by Starswirl the Bearded's standards. Not to mention potentially delicious! The pale white unicorn gazed over the inked incantations on his parchment. A spell for conjuring edible food, elegantly simplified through his own research. All a pony had to do was chew and swallow. Plus a little extra - a digestion spell for soothing upset stomachs. Equestria's restaurant industry would be revolutionized! Imagine the utility for ponies on the go! Nothing remained but to test it. Bright Spark put a hoof to his muzzle, thinking back to the meager hayburger dinner he had scarfed down hours ago. His tummy growled softly. He'd been in such a rush to finish his work that he'd even skipped dessert. Aha, that was it! "Well...how about a milkshake?" the unicorn said to himself with a smile. Bright Spark stared at the parchment as his horn lit up, visualizing the tasty beverage in his mind. Maybe vanilla...or perhaps strawberry? His horn crackled with power, then dissipated with a *poof* of energy. The stallion winced and looked about, but saw nothing. The unicorn's ears drooped. He rose on all fours with a sigh, preparing to sort through his stack of reference tomes to determine what went wrong, when something prodded his muzzle. Bright Spark flinched as an invisible something pressed against his lips. "Hrmm?" the stallion mumbled, tentatively opening his mouth. The invisible something snaked inside. It felt like a rubbery tube...or maybe a straw? He gasped as cool, invisible liquid suddenly poured into his mouth. It was...a milkshake! "Mmmm..." Bright Spark hummed approvingly as his mouth was filled with cream. The taste was indescribable - sweet and sugary, cold and thick - like the best milkshake he had ever had in his life. The unicorn gulped down a mouthful, shivering slightly as the substance cooled his throat. His hungry stomach grumbled as it was finally fed. "Ih worksh! Mmm..." the unicorn cheered to himself as more milkshake flooded in. Bright eagerly obliged it by gulping down another mouthful, then another, greedily sucking slightly on the straw as the magical cream flowed past his lips. Minutes passed as the stallion steadily gulped down his magical dessert. Bright Spark's eyes closed as he savored the cool, sweet flavor, his tail swishing happily as he drank. His stomach gurgled as it slowly filled with the magical substance, and the unicorn's middle began to slowly bloat outwards as he ate. Bright began to shiver, his middle feeling cold and numb as the cream sapped his body heat. A pang of fullness suddenly cut through his reverie. Startled, the unicorn reached a hoof back to touch the cold, taut flesh of his middle. His belly bulged out several inches, stretching to contain his nearly-full stomach. He shifted his stance slightly, causing his stomach to roll and slosh. A hint of worry crept into Bright Spark's mind, even as he continued to drink from the straw. The feeling of fullness was growing uncomfortable and more intense. The stallion felt a twinge of pain. His gut had swollen into a cold, hard sphere, his stomach stretching to its maximum capacity to contain gallons of the liquid dessert. Bright huffed, about to spit out the invisible straw, when the second part of the spell took hold. A wave of warmth suddenly radiated from his stomach. Bright huffed in relief as the pain and cold vanished. His gut gurgled loudly, churning and sloshing as it rapidly digested its meal. The hard, swollen sphere of his gut began to soften and recede. Suddenly the warmth in his middle began to spread throughout his body. The stallion shivered and shook his head at the pleasurable sensation. He blushed slightly as his nethers twinged, his stallionhood slowly hardening as he warmed up. He hadn't anticipated how GOOD this spell would feel! The unicorn failed to notice that his softening belly remained noticeably rounder, or that his trim rump was now slightly thicker than before. Bright Spark returned to eagerly slurping down the magical cream. His body felt delightfully warm now, the cold sweetness dissolving into warm pleasure as it passed down his throat. His stomach, no longer painfully full, instead roiled with magical juices as it digested his conjured meal. The unicorn's belly began to bloat outwards again, this time with soft, fluffy fat. His rear swelled rounder, rump cheeks divoting with adipose against his thighs. His legs and face thickened with a new layer of pudge. Bright Spark was in heaven. His cock was now inexplicably erect, the pleasure of the feeding spell somehow driving him to arousal. The stallion casually slapped his horsecock against his belly, ignoring how it caused his softening tummy to jiggle noticeably. Bright continued greedily sucking down mouthfuls of cream, moaning softly as drops of pre-cum dribbled from his dick. The sides of his barrel bloated round like a pregnant mare's, swelling past his thighs with newfound fat. His lower back began to dip slightly as pounds of flab weighed it towards the ground. The unicorn smacked his cock against his gut again, and a new ripple of pleasure nearly caused him to gag on his meal. His body felt so wonderfully warm, the cream was so indescribably tasty, his cock so pent-up that he could almost burst... Bright Spark's breath hitched as he came, his cock erupting and spurting ropes of seed across the chamber floor. The stallion huffed between gulps as his mind blanked with orgasmic pleasure. As the waves of bliss subsided his knees and back legs buckled and he suddenly lost his balance, falling backwards onto his chubby rump. The stallion gasped, nearly choking on a mouthful of cream as his bloated tummy was squashed against the floor. Hooves scraped against tile as he rolled onto his side, his exposed belly spilling out onto the floor. "Nnnnngh..." Bright groaned as his head spun. The unicorn's head slowly cleared, and he glanced around at the room and himself, suddenly aware of how fat he was becoming. His hooves groped the flabby swell of his belly and gave it a gentle shake. The stallion flexed his back legs, cringing as his fatty thighs and rear wobbled. 'Is this gonna stop soon?' Bright Spark asked himself. He wriggled his lips, muzzle scrunching as he tried to spit out the immaterial tube, but to no avail. His forehooves reached up to paw at his chubby face, but there was nothing to grab onto. He could feel the tube of cream inside his mouth, but his hooves could not! Bright Spark's eyes widened as nervousness gave way to panic. The spell...he'd FORGOTTEN include a way to stop it! The unicorn flailed his hooves about until they found purchase on the floor. Bright steeled himself, tensing muscles and then lurching sideways to roll himself upright. His body sluggishly complied, slowly rolling sideways until he was back on all four legs. The stallion gasped, sweat beading on his forehead as he felt the full weight of his fatter body. His bulbous gut wobbled between his legs, its flabby curve nearly touching his hocks. The unicorn's eyes turned to the door. He had to escape! Find his colleagues - find anypony! The unicorn jumped forwards, then stumbled as his back legs kicked against his barrel. Hooves fumbled as the weight of his swollen middle threatened to topple him over. Bright Spark steadied himself, then gingerly placed one hoof forwards, then another. The stallion adopted a loping waddle as he slowly made his way to the exit. Each step was accompanied by another sucking gulp of milkshake. Portly rump cheeks wobbled and sagged as his barrel continued to swell, rounder and thicker, lower and heavier... Bright Spark cringed as he felt his belly touch the floor, the friction of its fat bulk suddenly rooting him in place. The unicorn compensated by arching his back, pulling his pendulous barrel off the floor and enabling him to step forward. Another two steps - and his gut scraped the floor again. Bright realized in horror that his belly was bloating in time with each gulped mouthful of cream. He struggled desperately to amble out of the room, willing his thickening legs to keep moving. Come on! Just keep moving, just... *ulp...ulp...ulp...* a few... *ulp...ulp...ulp...* more... *ulp...ulp...* steps! Halfway to the door, Bright Spark's painfully arched back gave out. His bloated form collapsed back onto the floor, smushing his sloshing gut against it. The stallion let loose a frothy *BUUUUURP*, his maw empty for just a moment before more milkshake poured in. His legs flailed desperately as he struggled to walk, but it was no use. He was too big - too heavy! A hoof stretched plaintively towards the door, so frustratingly close but now impossible to reach. The milkshake continued to flow. "Mmmmph! Mmmmnnn!!" Bright Spark murmured in vain as he was pumped full of cream. His stretched, swollen stomach burned like a furnace as it digested his endless meal. His blubbery belly swelled wider and thicker, pooling onto the floor and pushing his hooves apart. His starburst cutie marks stretched and distorted as his chunky ass inflated with flab. Bright Spark fought back tears, back hooves drumming uselessly against his flabby gut as they lost contact with the ground. His front legs felt heavier and heavier as they thickened with fat, resembling plump white sausages. The unicorn felt his neck bloating into a ring of flab, squeezing into his chunky cheeks and thick double chin. Bright Spark's eyes unfocused as sweat dripped from his brow. His body felt intolerably hot, the heat of his gut now swaddled by so many inches of squishy new flab. The pony moaned as he felt his cock twitch. His member squished delightfully against his belly as it hardened. He flexed his buried thigh muscles and was rewarded with a wave of pleasure. The unicorn huffed helplessly through gulps of cream as he flexed again, his hefty balls squeezing between his massive ass cheeks, his quivering cock divoting into the swell of his lower gut. His fat flesh massaged his dick as he bloated and struggled in place. Bright Spark huffed and snorted and edged towards climax. His horsecock finally erupted again, spraying more seed against the bloated lower curve of his gut. Bright Spark lay there for seconds, his mind overcome with pleasure. Slowly he came to, flexed his limbs, and found he couldn't move his legs. Every muscle was buried under inches of heavy fat. The cursed milkshake continued to flow, forcing him to rhythmically gulp it down or choke on the sugary treat. Panic rose within him again. His body was swelling into an impossibly fat ball of pony pudge. The stallion feebly wiggled his forehooves as they sank into the flabby orbs of his legs. His back hooves were nearly buried beneath the weight of his titanic ass. Beads of sweat poured down his face and around the hefty tire of his pudgy neck. His gaze shifted as his ever-expanding gut lifted him further off the floor. Bright Spark's eyes screwed shut as he willed himself to stop swallowing the endless milkshake. His chubby cheeks swelled comically as his mouth overflowed with cream. The effort lasted all of three seconds before the pressure forced him to take a massive *GULP*. His belly shuddered as it bulged out another extra inch. A pile of books toppled over as his elephantine gut swelled across the floor and began to squish against the walls of his study. A dreadfully familiar feeling of fullness crept into Bright Spark's awareness. Salty tears streaked down his fat-swaddled face as his mind blanked in terror. Oh Celestia, he was getting so full! Pinkish stretch marks began to appear beneath the snow-white fur of his comically swollen gut. His belly couldn't fit any more. His body couldn't grow any more! Too big...tight...hot...oh Celestia, HE WAS GOING TO- There was a sharp CRACK of magic as Bright Spark disappeared. Open books fluttered and candles blew out as a rush of air filled the void where he had been. Nothing remained except a few stains of sweat and seed pressed into the matted carpet. The unicorn's food conjuration spell swished off the table and landed on the floor, its inked glyphs glittering in the moonlight.
