Contains: Massive weight gain, giantess
——
Tonight was something of a special night. Working for the same boss for nearly ten years was an accomplishment even as an assassin. That was why Leizu was nervous as she quietly walked behind her employer, Big Madame. It was almost comical how the seemingly lithe Leizu was completely invisible behind the heft of her boss. It worked for their dynamic, though. Big Madame was intimidating on her own, but people became especially pale when they finally noticed Leizu tucked behind her.
The view also wasn’t bad…
Big Madame was referred to as such for a reason. She was massive, more so in width than height. From hip to hip, she was wider than Leizu was tall. Each hip was a soft mound of fat that rolled down meaty thighs like barrels. Only “like” barrels as they were much too soft to be compared to the wooden contraptions. Her posterior was perfect in Leizu’s eyes (ironic as she kept them closed most of the time). It was like Big Madame had a couch with her wherever she went. Her white dress hugged these curves perfectly. It was natural, given that Leizu sewed them. She was as good a seamstress as she was an assassin.
Big Madame’s front bore its own masses of supple fat. Her belly hung to her knees and extended far enough in front of her that her arms could reach. It was like a barrier that kept anyone from getting too close. Whenever she moved, it pushed ahead of her like a battering ram. It made it wonderfully easy to entrap or intimidate someone. Her breasts rested above it and partially obscured her face. This was another factor of her mystique. They were like a veil that could hide part of her face when she needed or wanted to. It allowed people to focus more on her vibrant, pink eyes than her puffy cheeks.
Normally, someone would only see Big Madame’s face when she wanted them to. They simply didn’t expect to be dragged up to see it. Big Madame’s arms were as wide as they were long at their thickest point. Her forearms also seemed adorably helpless with how they were, too. Yet Big Madame knew how to move her body. A simple lean and reach would reveal surprising agility and strength as she hauled someone up by the collar of their shirt.
That was probably why Leizu treated her boss with reverence atop loyalty.
Leizu was quite striking in her own right. Dark blue hair was drawn up in a grey bow, pale skin matched the white and black of her Chinese-style robe. The robes hugged her form and made her appear slender. The truth was that she specially designed these. Compression clothing had become common in the last few years, and Leizu had readily employed it. Plenty of people needed to keep their true weight under wraps. Leizu mainly did it as it made her work easier. She sometimes loosened the compressive qualities around Big Madame as the large woman favored plump and obese figures.
That circled back to the specialness of the day. Leizu reached into a pocket and rolled a glass vial between her fingers. Big Madame’s claim to fame was a drug known as Expanse. It most often caused weight gain that could quickly result in users gaining hundreds of pounds. It was both potent and addictive.
What Leizu held was special, though. She had…persuaded one of the scientists behind the substance to make a modified version. This one would give her the ideal body suited to Big Madame’s tastes.
The two had just entered a private room, so the time seemed perfect. Big Madame lowered herself elegantly onto a couch which groaned in shrill agony under her weight. She sighed and leaned back. “Goodness, I nearly blew a fuse in that meeting. Good help is so hard to come by.” Big Madame chuckled as she reached for an ornate, oriental-styled pipe. She pressed it to her lips and drew upon it before exhaling pink smoke. “If only there were a dozen of you, Leizu…hmm, although perhaps that’s wishful thinking.” Her gaze stopped on Leizu, and she smiled. “I’m much happier appreciating you for how extraordinary you are compared to everyone else.”
Leizu felt her cheeks warm. “You are too kind, zhǔrén.” She said and bowed her head. This allowed her to subtly drink from the hidden vial. She was curious what Big Madame saw as the ideal form. She imagined it would involve a moderate weight gain. The mental image of being as large and shapely as Big Madame played in Leizu’s mind.
Big Madame chuckled. “As formal as always, Leizu. You’re free to relax a little. Today is our tenth anniversary. We’ll be sure to have a special dinner tonight.” Big Madame brought plump fingers to her chins. “Yes, perhaps we’ll dine at La Beauté Rondelette? What do you think?” Her focus returned to Leizu. “Oh my.” Those words didn’t carry any strong emotion. Instead, they were inquisitive and vaguely intrigued.
Leizu was so surprised that her normally closed eyes shot open to reveal crimson irises. This wasn’t because Big Madame had remembered her long stretch of service, nor how she referred to it as their anniversary, like they were a couple. No, Leizu was caught off guard by the sudden tightness of her clothes.
Compression clothes were meant to hide excess mass, but that didn’t mean they felt overly tight. That only happened when their threshold was near or exceeded. Leizu’s clothes were designed to hold her natural weight and an extra eight hundred pounds (just in case). The liquid she swallowed caused her weight to reach that limit within a second.
‘I had planned to gradually loosen my clothes…Now I don’t know how long they’ll last.’ Leizu thought and clenched her teeth.
Leizu’s entire outfit strained to contain her. The sash around her midsection felt tighter by the second, and a roll of fat bulged around its edges. Her sleeves were meant to be baggy, but now they seemed stuffed to bursting with her arm fat. The fabric that was supposed to elegantly flow over her thighs now struggled to wrap itself around the progressively more pillar-like thighs.
Big Madame stood and waddled over to Leizu. She giggled as she reached out to toy with Leizu’s sash. The tip of a thick finger traced the edge, gently prodding at the blubber hidden beneath fabric. “My dear Leizu, if I didn’t know any better, then I would think you tried to surprise me~” Big Madame cooed seductively as she wrapped her arms around Leizu.
Leizu’s face turned from porcelain to pink. The close proximity alone was enough to crack her stern exterior, but Big Madame had her arms wrapped around her. She hugged tightly and tucked Leizu close to her chest. Atop that, her clothes continued to go beyond their limit. Threads began to split, and Leizu’s weight was being revealed.
The woman’s hips began to flare out. They gradually approached the width of her employer’s, but continued to swell. Her skirt split down its length and her robe was lifted by the expanding shelf of her butt. Smooth, porcelain skin, packed with fat, wobbled and swelled with each passing second. Her lower body grew thicker, fuller, and rounder as if it were being inflated. Yet, the curves and folds could only be supple, weighty fat.
“Goodness, larger than me? Leizu, you scoundrel~” Big Madame continued to tease as her fingers traced along new rolls of back fat. Her expression revealed complete enjoyment and intrigue at Leizu’s predicament. She continued to move her hands and feel for areas that were trying to expand. Leizu’s body had to battle the fabric meant to contain it, but Big Madame could tell that was a futile effort. Soon her dear confidant would burst free of them and grow to what she hoped was a lovely size.
Leizu felt her sash gradually loosen and then fall. What followed was a surge of belly fat that pressed against Big Madame’s. The wave of flab continued to roll forward, but it also rolled out to her sides with her hips. The progression from flat to potbelly to a hanging apron of fat was so quick that it could almost be called instantaneous. It maintained a luscious, round shape even when it sagged to her knees. One of Big Madame’s hands moved to it and pressed. Fat easily bulged between her fingers, which provoked her to squeeze more.
Leizu twitched with excitement. Her breath grew heavier, and her chest heaved. This, coupled with her growth and strained clothing. The front of her clothes tore, and her breasts readily swelled. They continued to grow with every second, like the rest of her, but their approximate size was thrice that of her head.
The continued growth gradually became too much for Leizu to handle. She was strong enough to handle her usual weight and then some. Yet as hundreds of pounds neared a thousand, Leizu felt her knees buckle. She had to wrap her arms around her employer for support. Her hands squished handfuls of back fat. She felt her arms swell further with pillowy underarms and bulbous forearms. They squished against Big Madame, but the woman didn’t mind.
Leizu’s clothes were now at their upper limit. The swelling fat moved to her face, and her angular cheeks rounded out, and her neck thickened. She took one more deep breath in before a chorus of fabric ripped all at once. Her vision was focused on Big Madame’s, but the corners of it were suddenly filled with her body. The sensation that assailed her was complex. It was as if gravity pushed down on her, but at the same time, her body rushed out in all directions. Her compression clothes no longer covered an inch of her. Their restrictive qualities vanished, and the drug Leizu consumed was still taking effect.
Her hips and butt rushed at the walls behind her. They slammed into them and piled higher until they nearly reached the ceiling. The surfaces already started to crack and bow, but they held up against Leizu’s rear for now. The soft cheeks continued to curve in their feminine shape, though. Her legs were still to her sides, but the thickness of her thighs was more comparable to a tree trunk. Not a lithe, slender sapling. Nor the average tree of a forest. No, Leizu’s thighs compared to trees in spacious fields, ones that prioritized growing wide, as opposed to tall. Yet instead of a thick, sturdy trunk, Leizu’s thighs were bulbous, gelatinous, and covered in waving curves. They were hardly legs at this point. They were so impossibly fat and still growing.
Leizu’s belly had surged outward in a similar pattern. It squished against her legs, but only managed to roll over her lower legs. That eventually allowed it to touch the walls to her left and right, while it also flowed forward to the wall ahead of her. The fat began to climb as it billowed in these directions. Yet atop it was Big Madame. She knew what was to come, so she simply jumped. It was perfectly timed so that she could lie atop Leizu’s belly. She simply continued to smile and propped her elbows up on the swollen mass of Leizu’s breasts, which were now rapidly surpassing the size of beachballs.
Leizu couldn’t break eye contact with Big Madame, even as her peripheral vision filled with the plush mass of her cheeks and extra chins. She stared as her body put further strain on their surroundings. The hidden floor was a spiderweb of cracks, and the walls were due to collapse at any second.
That second came with chaotic results. Leizu had felt pressure build as her body demanded more space. The walls were unable to deny that space and crumbled like a clump of dirt. New rooms were forced to host Leizu’s abundant flab, which rushed like a tidal wave. Furniture was crushed, and the next walls were hit with enough force that they too collapsed. Leizu felt her breath hitch as strange pleasure assailed her. It felt sinfully good to grow like this. Every new inch embracing the floor, smashing an object, or simply quivering with movement was enough to make her moan.
Big Madame seemed to enjoy that. She laughed a throaty chuckle as she caressed Leizu’s cheek. “My, so expressive! You’re normally quite reserved, but here you are making such excited noises~” She looked at her employee with affectionate eyes.
Leizu blushed as Big Madame crawled closer to her face. She felt her boss’s hands squeeze her cheeks, and she felt the woman’s belly drag over her expanded chin and neck. It took a few seconds to realize this wasn’t simply to get closer. Big Madame tucked herself closer to Leizu because the swelling woman’s fat was near the ceiling.
Yes, Leizu continued to spread outward, destroying another series of walls, but her ass, thighs, and underbelly had grown enough to push her higher. She felt what was probably her shoulders and what was undoubtedly the upper curves of her butt cheeks press against the ceiling. This was harder to break through, but eventually Leizu succeeded. Thankfully, Big Madame used her hat to shade both of their faces from debris.
The growth refused to cease. Leizu had dwarfed her former size like an elephant dwarfs an ant. “Certainly…your tastes…are quite demanding,” Leizu murmured.
Big Madame threw her head back and laughed heartily, so heartily that her belly rolled enough to bounce her chest. She giggled and chortled until there were tears in her eyes. “Oh, my tastes? Yes, yes, it seems you intended to reach my tastes.” The woman calmed herself. “I was beginning to think you were growing rather large, but if you mean to reach MY tastes. Oh, dear Leizu, I am sorry to say that you are barely a fraction of the way.”
Any other person would have blanched at that, but Leizu did not. “I see,” She murmured and focused inwardly. “I have but one regret, and that is not selecting a more open venue for my surprise.” Leizu finally chuckled. She already weighed numerous tons, and an untold amount awaited. The surges of her body were intense, but she would remain sane through them all. Big Madame loved all things pudgy, obese, and immense. Surely she loved how enormous Leizu had become, so she owed it to her employer to love it too.
Rolls thickened beyond slabs. They stood as tall as the walls that feebly tried to hold them back. Her assets reached new heights, their curves broadening but maintaining. That way, Leizu was not consumed by her flab. Anyone who stood far enough away and wasn’t buried by her would see the noticeable curves of a woman.
Titanic breasts new smashed through new ceilings before Leizu’s shoulder neared them. Each was large enough that they could nearly fill one of the rooms each. Noticeable bolts of pleasure rocked Leizu’s spine as dangerously sensitive nibbles pressed against…well, anything. Leizu could not see the furthest, pink peaks, but she certainly felt them push against, displace, or destroy things. She was forced to bite a slightly plumper lip to resist noises that would damage her pride. The ones early were permissible. The ones she wanted to loose now…too indecent.
While not providing as much pleasure, Leizu’s rump made up for that in destructive power. They moved with the force, speed, and chaos of a tsunami. They had risen through four ceilings, and now seemed to break free of the feeling. Leizu assumed this as she felt the breeze on both of her hips. Doubtless, the city was now alert for a giant rising bottom instead of what they assumed was an earthquake.
Leizu didn’t care. Let the entire world see her nude and impossibly obese. All was worth it if she gained the ideal body for Big Madame. She would grow to destroy the entire city if that made the woman atop her happy.
The city was a lofty and distant goal, but it seemed Big Madame at least desired a woman large enough to smash the building they had resided in, as Leizu’s belly and accumulated side rolls had destroyed the rest of the foundation. After a chaotic collapse, Leizu now occupied the space that the building previously had. Her belly was slightly shorter than her butt, but the curve and cascade of her midsection stretched nearly three times as far. Its path of destruction was like that of a lava flow. Rapid, but lower to the ground. It swept anything and everything out from under itself. Nearby streetcars? They tumbled until the flab overtook them. Shops and businesses were flattened much more easily than their predecessors had been. Eventually, they just vanished beneath Leizu’s folds as they gradually grew taller. Whereas her highest point was equivalent to a ten-story building, her lowest point was at least a single story.
Legs, hardly fitting of the name, wrought similar destruction. They at least had some space to subsume objects. The inanimate sort, like trees, telephone poles, and even a celebratory statue of the city’s founder, were sandwiched in the fold between what used to be Leizu’s thigh and knee.
Leizu’s arms were perhaps the smallest affair. They had simply been swallowed up. They were but comparatively tiny lumps on her upper sides. Still, Big Madame tenderly caressed the nearest part of them.
Speaking of, Big Madame stood. She was shaky at first, but her balance steadied. She gazed out at the increasingly impressive view. “Perhaps this sight is more romantic than the dinner I planned.” She suddenly sat down, her rump barely a foot from Leizu’s face. Leizu blushed, but Big Madame didn’t notice. “As you grow, I can’t help but think.” She tapped her soft chin. “I have an ideal size, what I see as the ultimate goal…but can that apply to you?”
That caught Leizu’s attention, but she still didn’t speak.
“If you are growing to my ideal size, what would happen if I desire you bigger?” Big Madame looked over her shoulder. It was just enough for one eye to meet Leizu’s. “Leizu, you are one of my treasures. You should exceed my expectations, which you have done with this wonderful surprise. Now, exceed my expectations AGAIN!”
It was like something called from deep within Leizu. It could have been the ring of a servant bell, the bang of a gong, or just a subtle coo from the woman she desired most. The result was the same.
Leizu grew.
Outward. In all directions.
Leizu again had to bite her plump lip to deal with the sensation. Her body, which rivaled buildings in size, rushed and surged out further. Anything at street level was instantly swept in the flood of her belly, hip, and butt fat. Shorter buildings were rolled over, and taller buildings were enswathed in rolls that rose higher than a tsunami. The outward growth was rapid and tremendous, but Leizu’s upward growth also astounded. Wind rushed around her head and over the grand curves and mounds of her fat-filled flesh as she soared higher. Big Madame even had to hold her hat lest it be torn away by the wind.
Over the gale, Leizu swore she heard Big Madame laugh in utter delight. All Leizu could do was let out a muffled moan.
Every inch, and there were countless inches at this point, was alive with pleasurable electricity. She felt each new fold bulge and swell. The sizes she reached should have been considered impossible long ago, but she couldn’t help but be astounded that there was still more. She knew her employer loved the excessively plump and large, but her proclivities certainly knew no bounds.
Leizu had completely buried the entertainment district and had long since flooded others. She could feel water lap at some folds as she poured over the water front, she felt the pressure as her blubber pushed past the tall buildings of the business center, and even residential quarters were subsumed by the towering wall of her butt cheeks.
Leizu was a growing mountain of fat. No structure around could compare to her in height, and certainly not in width. She bulged and swelled with a vast stretch of belly fat that was composed of tiered rolls. Each was like a giant slab that dwarfed the buildings that were likely flattened beneath her. Her hips flared out greater than the width of the entire city. They rolled across the open ground that began after. Any trees or shrubs that were there stood no chance. They all vanished the instant her fat rolled over them. Behind her, her butt cheeks managed to rise higher than her head by hundreds of yards. Just the same, they continued to reach out behind her and took up all the space available. Any sense or sort of limbs were nonexistent. Leizu was too impossibly fat for them to remain visible. There were lumps attached to her hips, and the mounds next to her head likely housed her arms. Yet, how could they be considered as such with how engorged they were? Before her, Leizu’s breasts rose higher and blocked out any view of the distant horizon that she assumedly raced toward. The pristine, pale mountains tingled in the cooler air as they stretched into higher altitudes. The sensation even sent a shudder through Leizu, which grew stronger as it carried through her folds and eventually caused the ground around her to shake. Finally, her face was mostly bulbous chins and thick neck fat, but Big Madame could still spot the sharp eyes and plump lips of her companion.
“Simply marvelous.” Big Madame leaned in and planted a kiss on Leizu’s cheek. “Perhaps you’ll stop soon, but let’s keep an open mind for the future.”
Leizu smiled. “You are too kind. I am simply happy to serve you. Even if my body grows until it buries the next city.”
Big Madame threw her head back in laughter. This unintentionally thrust her belly toward Leizu’s face. Supple fat squished against her, but she said nothing. “Oh, Leizu, you’re normally so reserved. Though I feel it must be hard to remain that way when you are this massive.” She used a gloved hand to dab at her tears before she patted Leizu’s cheek. “But,”
Leizu listened intently. What did that “but” mean?
“I can’t help but feel left out.” Big Madame pursed her lips and thought. “Would I be encroaching upon your gift if I 'let loose,' as they say?”
“By all means, I would be overjoyed to share this moment with you,” Leizu replied, eager to see what would come.
Leizu knew more than anyone else that Big Madame’s portly size was only the result of the strongest compression clothes. She had never seen her employer’s true size, but it seemed like she was about to.
Big Madame smiled. “Leizu, my dear, sweet Leizu. If you think you’re big…” Big Madame paused as her hands slowly, so very slowly, reached for her belt. “Then you are in for quite a surprise~”
With a flick of the wrists, Big Madame removed her belt, and Leizu’s vision was instantly filled with a rush of belly fat. This entire evening was meant to be a gift for her employer, and here she was being given an even greater gift…
THE END
