A Series of Weight Gain Flash TF Stories for Tail-Blazer 

Ms. Rabbit Butt and Belly WG

“My, my. That was certainly an experience.” Ms. Rabbit said to nobody in particular. She punctuated the words with a gentle twitch of her nose, closing her eyes to lose herself in the memories once more.

 

It started with a rumbling in her belly, and not one like she’d ever experienced in her life. Naturally, she’d felt butterflies in her tummy—namely when she was around Mr. Hare; she’d felt the growing rumblings of hunger; and she’d even felt the delightful contentment of a fullness, the kind that could only be borne by gorging herself on carrots.

This; however, was a different sort of rumbling entirely. She pressed an inquisitive hand against her corset, eyebrows raising as she physically felt motion beneath the plump pads of her paws. “My goodness!” She exclaimed. “Wh-UFF!”

Whatever she’d intended to say next was cut off in a huff, as her belly ballooned outwards. Her poor bodice wasn’t built to handle such a bunny belly, and the strings lining her corset split immediately. She watched the fabric sail from her body, exposing her newly pudgy paunch—though it wouldn’t simply stop at ‘pudgy’.

Indeed, with every breath she took, Ms. Rabbit felt her stomach swell out larger and larger, pounds of chub giving her a distinctly rounded appearance. She tilted her head inquisitively, the earrings in her left ear jingling slightly. “I certainly haven’t heard of such a malady afflicting anyone in this town. Perhaps I’m the first? That wouldn’t do at all, I wouldn’t like to be the center of attention!” The brunette breathed.

Quickly, she looked left then right, ensuring that nobody was watching her. Then she began to hurry towards her secret place in the park, a location known only to her and Mr. Hare. The bunny woman huffed, sweat beading her furry brow as she struggled to walk with the additional weight. She cupped her hands beneath her rounded gut for support, as though she could lift her belly, and somehow move faster.

Her belly protested against this, growing heavier and heavier in her arms. Soon her staggered walk slowed to a tubby waddle, the kind she’d associated with the portly Mrs. Hippo from down the block. Luckily, she made it there just in time… Just in time for her butt to blimp, that is.

“No! What now!” The lagomorph anthropomorph huffed, a look of distress in her eyes as her last steps became increasingly wobbly. Her body was unbalanced by the weight in her belly and the weight in her butt at the same time, and she found herself rocking back and forth like a pendulum. Finally, the greater mass won out, and she fell with a loud huff onto her massive, rounded gut.

She looked to her rounded backside with concern, wiggling her plump cheeks. “Heavens!” Ms. Rabbit gasped, before a rather devilish idea slipped between her long ears. “Although… Mr. Hare did say he was rather fond of having more to love…”

 

Tracer Butt and Thigh WG

“Lena Oxton: British brunette, Overwatch agent, and center of ninety-nine percent of the Internet’s aggression.” Tracer sighed to herself, looking at her reflection. “Honestly, I don’t see what’s got everyone so knackered. It’s not like my tush is that notable anyways.” She said the words aloud to nobody in particular, intending for them to be a self-deprecating joke.

However, her thighs and butt took a special offense to that. She spent all day keeping them constrained within tight latex, and always exercised so often—and she had the nerve of claiming they weren’t worthy of attention? Well, that could certainly sort itself out.

Blissfully ignorant of her posterior’s machinations, Tracer dropped her pert butt down onto her bed, flopping her back down onto it. “Really… So much controversy over such little things.” As she spoke, her hips began to lift from the bed, her cheeks swelling with a jiggling, soft flab. The girl didn’t notice at first, too preoccupied with her own predicament. Nor did she notice the supple thickening of her thighs, growing from slender things that she could wrap her hands around into pillows she’d be pressed to fit her arms around.

It was only when her hindquarters had gained a few dozen kilograms that she’d noticed—and that was only because her bed had begun to creak. The girl looked down towards her feet, yelping as she realized that her hips were lifted a half-meter in the air. “What the bloody hell?” She gasped, her jaw falling slack.

She’d never seen such a blossoming butt before, nor had she seen such titanic thighs. As such, she was completely unprepared for what to possibly do with them. The best thing she could think of was righting herself, before the blood rushed to her head.

This proved to be a little more of a challenge than she’d expected. The weight in her hindquarters was simply too great to be offset by the flexing and curling of her lithe frame. Luckily, her bed wasn’t built to handle the weight she’d packed on, and its legs cracked beneath her.

The motion threw her forward, and Tracer gasped as she found herself lifted atop her bottom. It continued to grow beneath her like an inflating blimp, and the girl pressed her slender digits into the sides of her bulky bottom. “Someone, help!” She called out, struggling to walk but finding herself unable.

The brunette looked towards her feet, crying out in horror as she saw why: her ass was simply too large. Her feet couldn’t reach the ground if she wanted, and the best she could do was bounce them against the jiggling flab of her butt. “No! This isn’t what I’d meant by a noticeable tush! I don’t want anyone to see this!”

If there was one thing that Tracer should have learned from her experience today, it was that she shouldn’t tempt fate. No sooner had the words slipped from her mouth than a Latina figure chanced upon her swelling butt. It was Talon’s resident hacker, Sombra, who’d been stationed in the same post for reason-y reasons.

“Oh, pobrecita.” Sombra purred, holding her thumbs and forefingers forward as though she was framing a picture. A holographic camera flickered to life between her digits, and she rapidly began to click pictures of the swollen heroine. “I can’t imagine how embarrassed you’ll be once the whole world sees you like this.”

Tracer could only wail in abject humiliation, a perfect expression for the tabloids.

 

Daisy Full WG

Princess Daisy was excited to be joining her fellow Mushroom Kingdom inhabitants in Smash—so much so that she didn’t notice the powerup until it was too late. Her fingers brushed against a rather rotund mushroom, and she absorbed its essence into her body with a faint gasp.

“Oh!” The athletic princess breathed, feeling a tingling across her body from head to toe. The brunette looked down to herself, expecting her uniform to shift from her tight tennis outfit to… Well, she didn’t know. Daisy knew that Super Mushrooms would give her an increase in stamina, size and power; Golden Mushrooms would give her a burst of pep and speed; and Weird Mushrooms… She didn’t want to think about Weird Mushrooms, but she knew that much like the others, it would come with a change in form and occasionally in clothing.

This time, it didn’t seem like anything was happening, a nonchalant normality relaxing the princess. “Well… I suppose it was nothing.” The woman muttered to herself, her eyes widening as a power-up jingle punctuated her words. Her body tingled again, and this time she knew that something was wrong—just as she knew there was nothing she could do about it.

The princess squeaked as her body began to feel unnaturally tight and weighty all at the same time. She cast her gaze across her slender frame, yelping in distaste at the sight of new bulk settling along her body. Her hands and feet were gaining pudge just as her arms and legs swelled. The new fat jiggled as her belly bloated, inflating and puffing up and out.

In a matter of seconds, she’d gone from a lithe athletic frame to something rather spherical. Daisy squealed, struggling to run for help. She made it a few steps before her gait slowed to the ungainly steps of a Thwomp, then to the humiliating waddle of a Goomba. A few more steps and her bloating body was beginning to swallow her arms and legs, stripping from her the ability to walk.

The best she could do was roll, and even that wasn’t much. Her muscles weren’t as enhanced as her fat, and so all she could do was jiggle to and fro in place, huffing with clear discontent. A look of consternation spread across her features, and she exasperatedly groaned aloud, even as her cheeks puffed. “I can hardly play tennis like this!” She pouted. “Much less participate in Smash!”

From behind a set of bushes, a lanky villain snickered. He’d unleashed the powerup, but had no idea that it would be so successful. “Finally, it’s Waluigi’s time to shine!” He cackled, unaware of the fact that he’d just made Daisy an undefeatable goalie in his favorite sport, soccer. But that was a tale for another day…

 

Carmelita Fox Breast and Butt Gain

Carmelita looked to the idol in her hands dubiously, her nose twitching as she figuratively smelled mischief. Then the blue-haired fox sneezed as she literally sneezed mold. “Lovely.” She muttered, wiping her nose idly with a gloved hand. “I take it that Sly’s behind this somehow.”

She sighed, her tail flicking idly as she set the idol against her desk. “Well, either way, our ‘anonymous patron’ has decided this should be returned to a museum. So let’s work on that.” She cracked her slender fingers, looking to the lit screen of her terminal. “First, we’ll need to find exactly what you are.”

As she leaned forward in her chair, it creaked below her. She paid the sound no attention, blissfully unaware of the fact that her butt was beginning to grow. The vulpine woman’s fingers expertly clacked across the keyboard, a shadow looming slowly over them as her chest began to expand as well.

“Hm. ‘Ancient Sumerian Fertility Idol.’ That seems to fit the bill.” She grinned. “So, we’ll need to send you off to the exhibit with…” She trailed off, scrolling down on the datasheet she’d found. “A warning? ‘Caution: Do not handle without proper protective gear.’ Well, that can’t be good.”

Carmelita looked down to her hands in consternation, examining her gloves. Nothing seemed off about them, so she turned her attention back towards the idol. “Though… It doesn’t look like you’re doing anything to me. Still, I’d better be safe and get you in a proper storage unit.”

She moved to rise from her chair, and her chair rose with her. A blush crept across her cheeks as she felt its handles dig into the sides of her posterior, and she looked down in distress. “Oh, this is bad, this is really bad. My ass feels like it’s twenty pounds heavier!”

The vulpine officer pressed her hands hard against the chair, leaning forward and trying to push it from her form. In doing so, she became keenly aware of the fact that her bust had swollen. With an undignified yelp, she fell hard onto her breasts, the soft flesh of her mammaries flattening her laptop. “N-no way! There too? I don’t want to have this mammoth-sized breasts!” She gasped.

Her body continued to swell, against her every wish. Her frown only spread across her muzzle as she looked out to the door, huffing as her pants tore and her shirt split down the middle. “Someone, get help! Call a medic, or… A fitness trainer! What are you waiting for, an invitation?”

She ranted and railed against her growing bulk, developing fetishistic proportions that put even the idol’s to shame. The chair’s arms broke against her fattening bottom, freeing her from its constraints and letting her rise to her feet.

She wobbled unsurely on them, extending her arms to keep her balance. Her breasts were the size of beach balls now, and her butt cheeks were somehow even larger than that. “When I see Sly, he’s really going to get it…” She glowered idly, an ear twitching in exasperation.

 

Secretary Belly and Boob WG

Nicole tossed her hair behind her shoulder, looking to the woman before her exasperatedly. “I told you, Mister Evans isn’t free at the moment. But if you’d like to wait, I could certainly take your number for him. Lawyers can’t just drop everything on a moment’s notice, you know.”

The woman, a redhead with an arrogant smile, tutted. “Oh, you poor, poor deal. Robert didn’t tell you about me, did he?”

“Mister Evans,” Nicole corrected the woman, “did not. Whatever arrangement you have with him isn’t with me, so I’ll need you to take a seat or get out.” She smiled sweetly. “I tried to use small words, but if you need me to I can say it slower for you.”

“Mn, and he hired a real firecracker to replace the last one. I like you, girl.” The redhead smirked. “But you still need to be punished for your lip.”

“Oh really?” Nicole leaned back in her office chair. She’d been threatened before, that tended to happen when working for a lawyer. In truth, she kind of liked it, the rush was exhilarating and it always left her a story for her boyfriend.

“Oh, really.” The woman smirked. “Let’s begin with introductions. I’m Magdalene, and I can see from your little nameplate that you like to go be Nicole. I can see from your trim figure that you like to diet and hit the gym, so I feel we’ll start with that.”

“Start with what?” Nicole blinked in confusion. This ‘Magdalene’ wasn’t like the other lunatics who’d gotten upset with her. This woman was something else entirely, a cold air of dominance about her that set the secretary’s nerves on edge.

Then she felt it: a gurgling, rumbling sensation from her belly. A faint whimper slipped from her lips as she looked down to her toned stomach, watching it begin to bloat. She could feel her skin getting tighter as new flab sloshed into her body, stretching her frame, bloating it.

“What the—how are you doing this?” Nicole whimpered, groaning as she felt the doughy flab with her hands. “I feel so big now… This isn’t possible! God, it’s like I’m being stuffed full of fat!” Her cheeks burned as her belly rounded further, visibly sagging over her thighs.

“Mn, less of the ‘G’ word. I think you’ll find that ‘He’ can’t really help you right now, anyways.” Magdalene smirked, pressing her fingers against the soft pudge of Nicole’s new pot belly. “It’s a start… Though we can always do better.”

“Better?” Nicole whimpered, then yelped as the chair below her vanished. She fell hard onto her back, moaning as the bulk jiggled with the motion. It didn’t feel bad, but it certainly didn’t feel good either. Disgust and discontent swept across her face, and she clutched at her new rolls of fat, able to fit her fingers between them. “How is this better?”

“Well, it’s certainly not good for you. But I’m amused.” Magdalene clicked her fingers, and Nicole found herself moaning once more. “This time, we’ll give your boyfriend something to love. I’m assuming you have one, given how cute you are. Oops-how cute you were. Sorry, I do tend to mux up my tenses.”

Nicole only moaned louder in response as her breasts began to swell, swaying and shaking with every breath she took. She could feel the soft globes growing rounder and rounder still, heavily pressing down against her. She cupped a hand around one, moaning as it sagged around her hand, as though it was swallowing her fingers and her palm alike.

“There’s so much…” The secretary trembled, panting in distress. She looked towards the witch—for what else could Magdalene possibly be—and let a tear slip from one of her eyes. “Please, no more… I’m too fat already, I don’t want to have this big belly and these big breasts…”

                                                           

“And I want to see Robert right now. But it seems like neither of us are getting that.” Magdalene sighed. “Still, I’ll see him eventually, so I suppose it’s only fitting your punishment ends here. Do be sure to tell him I stopped by-though I’d imagine he’ll be able to figure it out on his own.”



Widowmaker WG

“N-non!” The blue-skinned woman breathed, distaste on her face as her belly gurgled. “Give me the antidote to this, immediately.” She looked down to her communicator, eyes narrowed to the redhead on the screen.

Her voice held a degree of authority to it, which drew a wider smile from her agency’s resident mad scientist. “Sorry,” Moira began, her tone implying she was anything but, “but once the change has begun, it cannot be stopped. I did warn you not to try using that serum on yourself.”

“And I told you, I personally try every venom on myself to build an immunity.” Widowmaker replied curtly, before sending a dubious look down to her body. “You had promised that there was a cure to its effects.”

“I did no such thing.” Moira seemed to be genuinely surprised by this. “Was it over e-mail?”

Widowmaker’s belly gurgled again, and she looked to her stomach with a growing frown. “Yes… More to the point, what does this brand of venom do to the victim? Should I check myself into the medical facility?”

“Less that, more the gym.” Moira sighed.

“To the gym?”

Moira continued as though she didn’t hear her associate. “As far as our ‘correspondence’ goes, I’d imagine that to be the work of our resident mischief-maker. I’ll need to have words with her.”

The screen went dark, and Widowmaker sent a foul look towards her communicator’s screen. “What? No, get back online, you didn’t even explain yourself! Why would I need to visit a gym-”

Whatever she was about to say next was interrupted as her belly puffed out, bulging out in a sudden increase in weight. Her new paunch jiggled slightly from the suddenness of the motion, and her golden eyes widened in shock. She’d never been fat before, and so was singularly unprepared for the feeling of tightness to her clothing.

“Oh my!” She groaned, pressing her hands to her belly. She could feel them sink into the soft flab of her new stomach, and her scowl only deepened. “What form of venom is this? Is this what Moira was busy draining our funds for?”

As if in response to her question, her ass jiggled. She looked back to it in horror, opening her mouth to let out a curse. Before so much as a single word could come to mind, it bulged and wobbled with growth, puffing up larger and larger to the point where she had to lean forward to offset its weight. She dug her fingers deeply into the soft flab, a whimper of distress escaping her parted azure lips.

She could feel something still gurgling beneath her fingers, and she held her plump posterior harder, struggling to keep it from swelling further. Of course, the motion was as useful as spitting in the face of a storm. Widowmaker’s bottom swelled further and further still, forcing her fingers and hands apart. With its increased size came an increased weight, upsetting her balance.

The former ballerina took a wobbling step forwards, then another. She hated how her once-delicate gait was reduced to a slow waddle, but felt that she had to try to move. It was only natural to her: all her life she’d exercised to stay in shape. Unfortunately, her current shape had no taste for exercise, of any variety. A few steps in and her hindquarters were too swollen to make any forward progress. Worse, her engorged cheeks were actually dragging her back, pulling her

“Non, mercy!” With a heavily accented cry, she fell onto the plush cushion of her ass. The second the blue skin of her bottom met with the floor, her belly puffed up further, as though the flab was jealous of her butt’s jiggling. Her belly shook as it tripled in heft, puffing up further and eliciting a loud groan of discomfort from her lips.

She looked to her corpulent frame, her cheeks puffing slightly as even they swelled with chub. The woman looked to her door and wiggled her arms towards it. She couldn’t even move her legs, they were trapped between her cushiony ass and her engorged gut. “Someone, get Moira here to fix me!” She cried loudly, pounding her hands against her massive belly in a tantrum.
