When Diane Foxington steals a corpulent artifact, she doesn't suspect the weighty effect it will have on her.

This is a commission that adapts Huwon's Weight of the Curse comic (https://www.furaffinity.net/gallery/huwon/folder/1581510/Diane-s-Weight-of-the-Curse-WG-Sequence)).


Diane Foxington's days as a thief were long gone. She was too smart to go on stealing just for herself. Yes, she took much more satisfaction as the governor of California. In spite of the stress, in spite of the critics, she knew her talents helped people and made a difference. At midnight, crawling through an air duct, deep inside The Museum of Ancient History, Diane had trouble believing herself. She was once again playing the thief. The duct's tight, metal walls constricted her svelte shoulders. Her black top wrapped tight to her breasts, keeping her as sleek as possible. She crawled on a flat tummy. Her slender hips gyrated left and right as her lithe legs pushed her through. Her only light trickled in from the end of the duct, where slits allowed air to pass through. She reached the end of the air duct. Tight screws held a cover on it, but they were no match for her claws. She twisted the screws off, then gently set the cover aside. It was impossible to penetrate the museum from such a tight portal, and so, it lacked any security. Impossible for most people. The Crimson Paw slinked out of the duct and onto the floor of an exhibit. She rose to her feet on the marble floor. It gleamed under the moonlight streaming in from windows overhead. This was the Museum of Ancient History's latest exhibit, which showcased depictions of fat throughout history. Rubenesque paintings lined the walls, while glass cases featured sculptures and pottery of weighty figures. The chill of central air brushed through her black hoodie and yoga pants. On a prior visit, Diane Foxington had admired the exhibit. The Crimson Paw, though, had found one piece that she needed. It had sparked a dormant hunger within her. She would indulge that hunger that night. A tan, stone sculpture sat on a plain, white pedestal. It was a rotund, curvaceous figure. It stood on stout legs with a bulbous middle and fulsome breasts. Above its chubby face, its hair descended in braided locks. Diane grinned. "Finally! The last piece for my trove! The Golden Venus Idol! And it's all mine!" There was no case around the Idol, but that did not mean it was unprotected. It sat on a pressure switch which detected its weight. If the weight upon that switch was altered, it would trigger an alarm. Diane knew that kind of system well. All she had to do was replace the Idol with an item of equivalent weight. Based upon the Idol's material and size, she had deduced its exact weight. She reached into her hoodie's pocket and produced a small sack full of iron balls, ready to make the exchange. "Now all I gotta do is swap this with that, and..." Her other hand hovered over the Idol. She would need to place the sack at the exact moment that she lifted the Idol. Doing so required lightning quick reflexes. Simultaneously, one hand gripped the idol while the other hand dropped the sack. She pulled away the Idol and studied the pedestal. "Hah! Piece of--(BHWORP!)" A sudden burst of gaseous pressure popped in her stomach and cut her off. The pelt over her stomach felt strange, almost as if it loosened. With one hand on the Idol, she put her other hand to her stomach. To her surprise, she found a pooching belly. Just moments prior, it had been tight and flat. "Huh? What the...?" Her belly swelled further into her hand. It was soft and pillowy to the touch. The sensation pleased her, but she quickly chided herself. It was no time to take things easy. Her breasts grew next. They pushed into her bra, straining their back strap against her back, and their plush flesh overflowed her cups. "I'm growing?!" Her hand cupped a breast, and it even felt heavier. She admired her new curve. Then, it hit her: her breasts might impede her escape. With that in mind, she checked her rump. Her hand confirmed her worst fears as she found a pair of ass cheeks jutting out behind her in big, juicy orbs. Her pants' seams popped audibly before a loud rip, and her ass flooded through. Air brushed her naked butt. "Hngh! Ahn! It--it won't stop!" Her fingers dug deep into her fluffy backside, but she couldn't stop to relish in her luscious growth. She had to get out of there, fast. Before she could do anything, her belly burbled with more gas. Bubbles popped and erupted through her gullet, surfacing with a wet, bassy belch. "Ghuooorp!" As her body expelled gas, her belly surged with fat. She felt her pants on her belly, and she used her hand to confirm. Her gut now poured fat down past her waistband and over her pelvis. Its weight shouldn't have felt so good against her lower abdomen, and she certainly shouldn't have gotten chills. But she did, and her hand roamed her upper belly, which now domed outward with fat. She looked down to observe her stomach with her eyes, but she only saw her tits. They felt humongous, with their fat pursing around her cups and her bra strap pressed uncomfortably to her back. Her breasts burst her bra hooks, and they flopped onto her stomach. Her hand could scarcely cradle one. As their tender flesh inflated into heavy, rotund orbs, their stretching pelt wrought tingling pleasure. Diane couldn't bring her attention away from them for long enough to focus on escape. Her lower body fought for her attention, as well. Her thighs plumped into each other with thick, doughy rolls, while her hips bowed outward in curvaceous heaps of fat. Together, they sundered her pants down their sides with a loud, sharp rip. She put a hand on her butt and only found its top. The rest of her cheeks jutted out behind her and nearly down to the backs of her knees. Her fat was so soft, so heavy, so big. Emphasis on the word "big," as Diane reckoned she had no chance of fitting in the vent. By that point, she was grateful she hadn't entered it. She imagined its steel walls constricted around her bulging hips, and she grimaced with hypothetical pain. Her only option by that point was the door. The portal into the foyer was 15 feet wide. It was so incredibly wide that Diane could fit through, even after putting on a little weight. She put one foot forward. Her thick legs challenged her balance, as they pushed off of each other as she tried to point them towards the ground. She took one more step, and her leg was so fat that it had to navigate around the broad circumference of her other thigh, giving her a defined waddle. As thigh rubbed thigh, she drew subtle streams of bliss between her legs, especially as her upper thighs nudged up into her fatty outer labia. Her foot fell with a thud that trembled up her swelling body. Every threat to her balance posed a threat to her escape, and she rode out her body's oscillations anxiously. Even then, her body kept going. She felt her back against her butt as her love handles poured out behind her, pooling over her rump. She also felt her belly encroach farther down her legs, as her hanging underbelly clapped her thighs all the way down to her knees. It sure felt heavy, and she wanted to inspect its size with her hands. She reached down her sides, and her waist billowed with increasing layers of thickness. Her hands tried to reach forward, towards her belly, but they found her breasts instead. Her plump digits barely brushed her puffy areolas. Diane demanded to touch her belly, if only to test its size. She strained herself forward and pushed her fat hands between her breasts. As she touched her stomach, protruding under her tits, she accidentally placed pressure on it. Her belly gurgled and churned. It roiled with building gas. The strain on her stomach satisfied her, like a wonderful stretch coming from inside. Its burp rose to her esophagus and stretched her with firm pressure. Her lips parted, and her gut clenched on her gratifying gas. Peals of pleasure burst from her mouth in an echoing belch, "GhuWOORRRP!" In the aftermath, she caught her breath and her bearing. While the pleasure of her burp subsided, she realized she had stopped waddling towards her escape. She also found her lips closed much fatter and juicier than when they had opened. Her neck fat pillowed under her chin, and her cheeks plumped out under her eyes, into her vision. "Mph..." She grunted through thick lips. Her hands raised to push down her cheeks, but her paws were so rotund that they just got in her way. The pillowy girth obstructing her vision would've been comforting if she hadn't been in the middle of an escape. Still, she trundled towards the doorway. Her calves piled lard so thick that they sundered right through her pants with a tremendous rip. Her defeated legwear fell away in pathetic shreds of fabric. Unflagging, she went on. Every footfall landed louder than the last. She stepped forward with her right foot, and her incredible bulk pounded a huge thud into the floor. Her weight triggered a quake that reverberated throughout the exhibit and rocked its artifacts. She tried to raise her left foot, but her leg was too heavy to pull up from the floor. Instead, she shuffled her left foot forward along the smooth floor. "S-sho... heavy..." Her large lips and puffy cheeks impeded her speech. As long as she could shuffle forward, she could still progress towards the exit. She scooted her right foot forward. Diane set her weight on it, but her leg gave out. Her right knee buckled under her weight; the entirety of her weight fell on her left knee; her left knee buckled. "W-whoa!" Her huge ass slapped the floor and oozed far behind her. Its flesh was too heavy to ever draw up from the floor. Her tubby legs sprawled before her. Too much blubber stuffed them to permit her knees to bend. Her belly flopped into her lap and spread out to her shins. Its weight pressed her down into the floor. Falling, she lost her grip on the Golden Venus Idol. Her arms clapped into her waist rolls. The impact squashed her bicep flab wide and ripped them right through her sleeves. Her tits flopped over her gut. The force of their crash spilled them out under her hoodie. At that point, it only covered her neck. The Idol sailed overhead. The fall's impact struck her belly and sparked gas like lightning. Her gut tightened, wringing her burbling insides with a strong, satisfying clench. She expelled another belch, "BhuuWOOOORP!" That one ripped through her gullet and blew past her lips in long, gratuitous tones. She enjoyed the rich decadence of her burp so deeply that she paid no mind to the airborne Idol. Only after her expulsion ended did she ponder its whereabouts. In the next moment, a sudden weight hit her upper back, accompanied by a soft rustle. "It's in my hoodie!" At last, something went right. She could easily retrieve it from there. She blew a sigh of relief. Diane lifted her hand from her breast. Already, her corpulent forearm weighed so much that her muscles burned to lift it. She bent her arm at the elbow, and her forearm fat bunched against her bicep blubber. The two pouches of lard smooshed into tight rolls, and her bending arm squeezed them outward. She could only raise her forearm to a right angle, unable to pull her wrist any closer to her head. That was fine. She raised her bicep. While the underlying bone and musculature rose, her flab was so voluminous that it remained stationary on her sideboob. Grunting and panting, Diane struggled to lift it. With all her strength, she raised her elbow to eye level. Her bicep flooded against her cheek and over her eye. Its weight was too large to bear, especially since she needed more strength just to push it around her fat face. "I--I..." She raised her other arm. Desperation fueled her muscles, and she lifted her arm quickly. Just as quickly, it encountered the same problem. It was too heavy to push and too big to maneuver. She thrust her head backward, and she wriggled her waist, but she couldn't coax her arms any farther back. "I can't reach it!" She uselessly flopped and lurched within her floor-bound fat, and she only succeeded in clapping her rolls together. Their doughy slaps made beautiful, sensuous music, much to her chagrin. "Hrrgh! How could this get any worse?!" Defeated, Diane dropped her arms. Their broad lard pummeled her wide breasts, and her nipples spurted, shooting a warm, white liquid. Dampness ran down her bare tits and over her belly. Fluid gushed in rivulets through her fat, weaving through crevices and trickling over folds. Diane puzzled over the sensation before she realized her tits had sprung a leak. Below her eyes, her cheeks kept expanding. They puffed in bulges of fat that blocked out the bottom half of her vision. If she wanted to see anything, she'd have to tug those growing pouches down. She clenched her biceps, and her forearms fought to bend towards her upper arms, but their flesh failed to compress. So much plush pudge gushed into her arms that they couldn't even bend enough to reach her face. At the same time, her belly inflated endlessly, along with tits that swelled with an infinite supply of lard. "I--I'm... sinking!" As she felt them rise up, she pushed down. She did manage to lower her breasts a small portion, squashing them into her fat gut. Her fat fingers and chunky palms grasped at her growing boobs. Her tits felt bigger and more solid by the second. Milk bloated them, and her boobs ached with a surplus of fluid. She pushed down on her turgid teats. Her hands forced out thick streams of milk. The relief brought her to moans. She lost herself in the process. Her hands wrung milk from her as she forgot about her pudgening predicament. Two rivers of milk soaked her front and pooled on the floor before her. She needed an escape plan, and she couldn't make one while groping at herself. She opened her eyes, but she only saw darkness. She huffed out words through blubbery lips. "I... I can't shee!" Perhaps something obstructed the moonlight, and the room was pitch black. Perhaps the Golden Venus had blinded her. Then, she realized, her cheeks brushed her forehead. Her face had fattened over itself. Unable to lift her arms, she did the only thing she could do. She pressed down on her breasts. Her hands groped around in futility. As her palms forced out more milk, Diane did her best to ignore the pleasure of her gushing tits. Under the downward pressure of her fumbles, her stomach churned and groaned. Hot air bubbled and popped inside her swelling gut. It exploded through her esophagus with ringing, shuddering rapture, and she pushed harder, forcing her belch out. "GHOAARRRRP!" Her gut clenched the burp furiously. It passed her lips with such power that it blew her lips open and her cheeks apart. While she belted a loud, euphoric expulsion, she could finally see. She gazed upon a far larger pair of breasts. Beyond those, she saw the same doorframe that led into the foyer. She worried that it would be too slim for her. Her stomach emptied its gas. Gradually, the gaseous pressure lessened on her gullet. Her lips drifted shut, and her cheeks shifted back into place over her eyes. Once again, her fat hid the world away from her. She reached with her hands, but instead of grasping her breasts, they flipped through folds of swollen wrist flab. Her palm clenched down with her thick fingers, and they found pursing folds, as if her wrist formed a navel around her hand. She shouted in frustration, but only a muffled grunt came out. "Mmph..." Huge wrists swallowed her hands. They imprisoned her digits better than any handcuff. She resented that the force that imprisoned her, her fat, should feel so plush and luscious. She fought her fleshy confinement by pushing her right leg forward. Her thigh tensed, and she muscled it with all her might, but she moved nowhere. Her knee didn't even press into her underbelly. Instead, it pressed into layers of thigh fat hanging over it. Her foot, swollen humongous with lard, kicked dull against her calf. Lard poured so voluminously from her lower legs that her calves gushed far beyond her feet. As she wriggled and shuffled, she coaxed her hanging belly forward over her growing milk puddle. Her body was too heavy to move and too big to walk through. "Ughh..." Already, Diane's cheeks engulfed her face. Her body's growth knew no end, though. Fat pumped into every inch, every centimeter of her body. Her neck was no exception. New rolls filled into her neck. Each roll pushed all the others. A stack of rolls pressed up into her chin, surrounded her cheeks, and plumped under the back of her head. Diane couldn't see a thing, but she felt her neck slump higher and higher up her head. Her cheeks approached her scalp, and her neck raced her cheeks. "S-shomeone.. Nggnhh... help... me!" She turned her head left and right, nuzzling her cheeks. She craned it forward, pressing her nose into her numerous chins, and she pushed it back, cradling her head in luxurious lard. She fought to escape her fat. Its plush, welcoming hug incensed her further. How insulting, she thought, that such a good feeling should be weaponized against her. While Diane struggled internally, her ass struggled behind her. Its weighty dimples steamrolled over the exhibit. Priceless artifacts fell to the floor and shattered under her butt cheeks. With fat covering her eyes and muffling her ears, she could only tell how much she destroyed by the feeling in her rump. Her cheeks met the walls on three sides. Her lard flattened to her sides, and it pressed firm against the wall behind her. She guessed her ass must have been something like 100 feet wide. She grunted and groaned as the tightness of walls pinched in on her growing backside. Pound by pound, inch by inch, her fat traded its pillowy softness for aching pinches all around her. The more she grew, the harder the building itself constricted on her flesh. She moaned in pain to feel walls crush in on her--though it was her blimping outward into them. That is, until she felt relief. She heard a distant rumbling, while the aches receded from her butt. Drywall and wood beams fell over her vast ass. Diane's butt had distracted her so much that she hadn't realized her belly faced the same pressure. Walls pressed in around it on all sides. As much as she regretted her growth, and as much as she hated her debilitating weight gain, she wished it would speed up. After all, she could look forward to some measure of relief once her body overtook the museum. Her stomach blimped and mushroomed, and she felt it press her tits up to the ceiling. By that point, her arms were useless, and she couldn't even use them to milk herself. Her breasts swelled and ached with sloshing, churning liquid. When they met the ceiling, it triggered a deluge. Her nipples blasted milk. It pumped violently from her tits, rocking their fat. Rivers flowed down her folds, lakes formed in her dimples, and, at her feet, an ocean of milk made her an island of fat. As her breasts squished harder into the ceiling, it mashed more milk out of her. A sweet ache filled her stomach as it built up to its escape. Then, calamitous thuds and cracks celebrated her reward. Her stomach reaped sweet relief as it gushed through the walls around her. She no longer had to worry about leaving the exhibit. She was larger than the exhibit. The bulk of Diane's fat contributed to her circumference, making her wider in every direction. At a slower rate, it piled upon itself. It pushed Diane up from the floor and swelled far above her head. Her breasts smooshed hard into the ceiling. Her sideboobs surpassed her shoulders, and her back fat slumped against her scalp. She was so big that her own fat shielded her from above. That came in handy, as her wrecking ball tits pushed up with enough force to shatter the ceiling. Heavy, jagged rubble tumbled down her corpulent contours, leaving Diane perfectly safe. She had worried that she would never be able to show her face again, for fear of ruining her reputation. As multiple layers of fat overcame her head, she worried that she would literally lose the ability to show her face. Fresh air brushed Diane on all sides. Her ass tickled against dewy grass behind her, while her stomach rested heavy against the front parking lot. The two oceanic tubs of lard surrounded her. Above, her breasts mounted higher and higher. Her nipples felt larger than cars. The night breeze blew past them, and she shuddered with pleasure. For all her shame and regret, at least she could appreciate that much. Diane's belly burbled, low and damp. She did nothing but sit back and enjoy the oncoming storm. Gas detonated in her house-sized stomach. As big as it was, it contained quite a bit of gas. Sweet pressure ripped wide her gullet, hammering her throat with untold pleasure. A cry of joy forced open her lips with a big, sweltering gust. "BHURWOOOOORRRP!" But that pleasure was short-lived. Afterwards, she was stranded and trapped. Unable to move, see, or hear beyond her fleshbound prison, Diane was locked inside the solitary confinement of her own padding.
