Dreams of Curvy

(contains hyper breast growth including collateral damage.)

---

Ah, sleep, one of life’s best options for escaping the daily hell it puts people through. This past week had been especially stressful between project deadlines, witless coworkers, and management being detached from their workforce. There was only one cheetah woman out of twenty furries that seemed to know how the new mandated software even worked. It was only by her forgiving nature, and a paper trail, that she did not light the building on fire after clocking out every night.

But that was six hours ago, practically a lifetime away. A dresser clock lightly illuminated the spotted yellow and black fur of membrane style wings hanging off the neighboring bed. Minutes slowly ticked by, displaying the time to be around one AM as the dracat laid fast asleep. Warm spring air left her mostly without covers and spread in a messy heap, betraying her usual regal appearance. One hand had wormed its way between the hem of her button up Fate ZERO pajamas to scratch at the abs of her white stomach, the other flopped lazily onto its adjoining hip. Her legs rested bent at different angles, occasionally twitching in response to her dreams of chasing playmates across ground and through the air.

Xilimyth might have been out like a rock, but her roommates could attest she was not quiet like one. Bits of drool glinted off her whiskers with jaw hanging open to seep out more. The fabric of her shirt billowed out and deflated in a slow rhythm, matching the tandem of her deep breathy snores. The day had ended on a fulfilling high note after finally hitting the gym for the first time in weeks. All that pent up anger towards overpaid dipsticks got burnt off in a series of squats, legs presses, dumbbell curls. The cheetahs toned muscles ached with the dull fatigue of a hard workout, making it so much easier to rest for tomorrow.

Had anyone been watching her over the next couple of minutes, that would have been morally questionable, but also could have prepared the cheetah for an unexpected surprise. A sudden itching oozed over Xilimyth’s, causing the hand on her stomach to shoot up and knead her breast. Her little pink nose ruffled in a series of irritated snorts while shifting her position. The aching passed before it could truly interrupt her pleasant dreams and snoring once again resumed with face resting on her palm.

The only difference now was that Xilimyth’s lungs were not the only part of her expanding. With each heavy breath she drew in, the front of her pajama top pulled forward by two rising points. Fat grew at impossibly fast rates inside her already perky breasts, giving them an increasingly rounder definition under the fabric.

By the time the clock rolled over to two AM, her girls were already bulging over the rims of their once loose C-cup bra. Buttons drew tight in the developing dip between them in a fight to keep their increasing mass covered. Each new centimeter they filled out Xilimyth’s front drew the straps in back tighter against her defined shoulder ridges.

“Mm-hmm!?” Xilimyth eventually sputtered her last snore before eyes struggled open. She stared up at the ceiling, confused until the pinching against her back slowly registered. A quick glance at the clock had her reluctantly lifting onto elbows to take stock on what was causing such discomfort. In the dark lighting of her room it was hard for the half-asleep cheetah to notice that her pajama top was a lot more inflated than when she had gone to bed. The added weight of full milk glands and fat were nothing to her expertly trained muscles. “Ugh! Stupid bra! Don’t tell me all that lifting broke them…”

Xilimyth sat up fully with a loud fluttering of her wings. Eyes fluttered still half open while she fumbled in back to undo and redo the clasp of her bra. Letting the shoulder straps slip down helped ease the pinching upon re-clasping it, but Xilimyth found her lungs oddly pressed in when trying to give a small yawn. That she could deal with in the morning, though. She flopped onto one side, eager to resume her pleasant dreamscape with the few hours left before work.

Somehow upon laying down the pillow had found its way between Xilimyth’s arms. It forced her biceps apart, heavily squishing the tender soft mass between them, making the cheetah growl at being forced more awake. One hand reached back to yank it away, only to grasp the familiar texture of pajama covering. Both feline ears and tail perked now in rising awareness. Xilimyth continued blindly rubbing and clenching her chest, finding a lot more definition and resistance under her usual sleepwear. Eventually this caused a sharp jolt of pleasure to rush through her spine, finally forcing the cheetah to bolt upright again with eyes open and aware.

“What the actual heck!?”

Both hands shot up to rest upon Xilimyth’s breasts. The notion they made contact much sooner than they should have sent her tail thrashing against a still warm pillow. Her once sharply defined mounds had already upgraded into thickly inflated balloons that spilled over undersized cups into her fingers. Worse was how holding them allowed the cheetah to feel their growth still continuing. Tender fur and squishy fat continued rolling forward aggressively pushing back her palms.

Wings gave a hard flap, helping Xilimyth spring off her bed onto quivering paw feet. The weight of her growing boobs were being felt now in all their bouncing glory. Small gaps opened between her pajamas buttons as it looked like she had cartoonishly padded the inside. A few awkward shakes of wide spotted hips and thick tail regained a little balance for the alien size. Enough for Xilimyth to feel confident heading for her room’s door, anyway. She needed to get to the bathroom, find out what was happening to her, and hopefully get things under control before…

“HNNNNNGH!!”

Xilimyth was only halfway to the handle when exactly what she feared happened. Hard muscle cramps seized her ribcage, transferring the energy directly into her engorged breasts. She could feel their insides filling near instantly, drawing white furred skin taut. She tried to fight the tension by forcing another step towards the door. That motion alone sent her chest stiffly bouncing like two inflated balloons. Bra cups could hold them back no longer and slid under the firm mammaries as barely effective supports for their hefty girth.

“Ngh! Haa! Haa! N-no! D-d-don’t!” The cheetah panted for breath, arching her back in response to another surge entering her chest.

Her boobs responded to the pleas with a soft rumble, followed by a rocking sensation that generated loud sloshing noises. Xilimyth slapped both hands on her butt, arching as far back as her spine could allow. Luckily she was a very limber cat despite hours stuck in a programmers office. The mammaries she reflexively pointed to the ceiling rippled violently with several hard pulses. Fat and milk expanded in them with audible gushes, like two halves of a ripening watermelon. The tender skin poured around her muscular rib cage, pushing off each other while excess flowed under her armpits. Her tender nipples prickled, rising like mountain points against the tightening pajama fabric and causing her loins to get embarrassingly wet.

“Gah!” Xilimyth’s abs flexed the best they could while still worn from the previous gym visit. She straightened up, only to get sent staggering into a soft crash against her bedroom door. The insane amount of new weight her girls gained in those few seconds were beyond anything she could prepare for. At least they were good at cushioning her impact against the cold wood.

Another jolt of pleasure rocked through Xilimyth’s groin. Damn boobies were becoming so delicate, even pushing her nips against the door was amazingly stimulating. She pushed the arousal back with a growl, focusing on exiting into the hallway in a dash for the bathroom. Funny how two giant water balloons bouncing on one’s chest can turn a few meters run into a mile of balancing issues. More than once did Xilimyth trip over her own feet, which were becoming difficult to see, slamming into nearby walls to remain upright. A trail of falling picture frames ended up in her wake.

“Aah!” Xilimyth flipped on the bathroom light and reeled back blinded. Nothing like staring directly into the bulbs to improve a situation. Toe claws clicked onto hard tiles in careful steps until she got a firm grasp on the counter. There she stayed, feeling the gentle wobbling of her mammaries with each breath until her eyes adjusted enough to assess the damages. “Oh… crap baskets!”

A quick turn for a profile view confirmed Xilimyth’s PJ top jutted out at least a foot at her breasts peek. The ample curve of their circular undersides had stretched buttons into wide gaps, allowing tufts of white collar fur to bulge out. She hunched over the sink, causing matted purple bangs to fall over her eyes, but they never left the reflected view of deep hanging cleavage. It was a miracle her poor anime sleeper could hold this much cheetah.

Shame that did not last.

“Nya-gah! O-oh…shiiiiit-haah!”

Ripples slinked up Xilimyth’s spine, fanned into an inferno under her ribcage and inciting a yowl. She rolled her shoulders back, fingers curled into white-knuckled fists on the counter, trying to brace against the pressure that poured into her already bloated breasts. A hard flex of her wings accidently slammed them into opposing walls, knocking off the shower curtain and towel rack in a loud metal clattering.

An aroused gasp sprayed spit across the shelf of Xilimyth’s bust moments before it cascaded forwards. The mirror gave a perfect vantage point to watch the soft globe squish against each other in a fight to take up whatever room remained in her PJ top. Soft tidbits bulged out the space between buttons, causing them to bend. Lots more poured out from under the hem, seemingly without end. A sudden pinch made her yelp as nipples engorged from the pressure to tent through the fabric like mountain peeks. Legs shifted but had no way to prepare for so much instantaneous growth.

“YEEK!”

With a loud pop, the cheetah’s favorite sleep wear finally lost the war. The pressure of Xilimyth’s god-tier cleavage snapped off every front button, many of which hit the mirror with enough force to break cracks in it. If that had not woken up her roommates by now the crash when she fell into the sink made enough commotion to alert someone of a potential problem.

Technically, it was Xilimyth’s tits that fell into the sink. Her sprouting milk bags had far exceeded conventional sizes in one surge, filling the porcelain bowl with rich cleavage. Excess flesh spilled out the rim sending most of the counter toiletries scattering around her feet. She waited for the rest of the bathroom to stop spinning before a few weak hefts eventually dislodged her breasts from the bowl.

“Good lord! Why did I swell as big as sis?” Xilimyth cupped the hanging mounds, looking dumbstruck at her shattered reflection. As if that busty and confused cheetah could answer her question any better. There was actually a sense of hesitation to feel that without even comparing them, she had grown even bustier than her sister. It was hard to even grab a hold with how wide and far they expanded out from her chest, hanging like curtains to cover much of her upper abs.

“Xili? Is that you?” Speak of the devil. Xilimyth’s ears and tail shot up at catching the low but tired voice of Brenda approaching on slow, heavy footsteps. “I thought I heard a crash. Are you all right?”

“Y-yeah! Don’t worry about it, sis. I just… oh, nya damn it!” Xilimyth spoke with an amazing calmness while the air conditioning assaulted her thickened nipples. It was only when she noticed in the mirror that the bathroom door had remained open that her tail fur stood on end. The ground shook slightly with approaching footsteps, eliciting Xilimyth to do the sensible thing and dive into the adjoining laundry room.

“You’re what? Ah!” Brenda reached the open portal, instantly recoiling in the sting of bright light. The cougar woman was nothing less of a giant she-hulk in her own right, seven feet tall with several hundred powers of powerful ridged muscles. Her extra-large t-shirt for this evening was a solid black with orange question mark blocks from a popular video game positioned over her beach ball sized bust. One meaty paw hand rose to protect her eyes, allowing the glimpse of a cheetah’s tail ducking behind the side door. “Nee-chan? Ack! Why is everything knocked over? Are you sure you’re okay?”

“I’m totally fine,” Xilimyth lied while sliding back into the room so she faced away from Brenda. “I just slipped trying to potty. You can go back to bed. I’ll clean this up.”

Everything she did only raised Brenda’s concern. Buff shoulders wedged their way in, preparing to demand what the cheetah was up to, only for her to pause with hand reaching for Xilimyth’s shoulder. A red t-shirt that tented the cheetah’s toned body replaced their usual pajama top.  It’s front bore the favorite initials of Brenda’s old college IAC.

“Did you just take my shirt out of the laundry?”

Xilimyth tried to suppress a shiver, forcing a barely audible affirmation noise. She was doing her damndest not to face her sister feline, lest they notice the way said shirt swelled out in front to make a shelf out of its distorted letters. “H-hope you don’t mind. My top got… uh, dirty?”

“Prrf? Of course not. But you know that shirt is for my… milkshake incidents, right?”

Xilimyth nodded vigorously, face burning bright red. Her sisters occasional growth spurts were exactly why this shirt had been picked. Brenda’s issues more involved occasionally over productive mammary glands and not… whatever madness was taking hold of the cheetah. Still, if this garment did not keep things contained through the night, nothing would. Wings gave an involuntary flutter while she silently pleaded for the cougar to just leave. Anything to keep them from seeing their sister so inflated like this.

“What the… Nee-chan? Did you stuff your pillows under there?”

Well, so much for tonight getting less embarrassing. The wing flutter had only been a second, but was all Brenda needed to see something amiss about her sister's silhouette in the bright light. Xilimyth had looked down and figured out the same problem a second later. The rounded curves of her breasts had fattened up even worse than feared, spanning nearly a foot past her shoulders to be visible even from behind her.They really surpassed Brenda’s boulders.

“I… I… gah! I don’t know what’s happening! EEK!” A firm cougar hand came to rest on Xilimyth’s shoulder, sparking her to whirl around with a startled cry.

Brenda could see her beloved family member was distressed, even if the reason was not entirely clear yet. Her biggest mistake had been leaning in to offer some words of comfort. That put the cougar’s chin in perfect position for when Xilimyth’s turn brought a pair of giant mounds into her face with the force of fifty-pound litter bags.

“PRRF!?” Brenda saw stars stumbling back to brace against the doorframe. As vision cleared, she remained staring in a daze at the warped cloth hanging over Xilimyth’s extremely pronounced front. "Wha bah huuuuuuh!?”

“Sorry, sis,” Xilimyth squeaked meekly. “I just started… blowing up and WHAAA!? BREN!”

Any explanation that could have been sputtered out fell dead when Brenda clasped both hands onto her sister's chest. It took three solid yanks to convince her the things bulging out her shirt were real. Xilimyth’s blushing mews and hip wiggling helped serve as further evidence of authenticity. Only then did Brenda’s rational thought made her realize what happened and yanked hands behind her back with an equally intense blush. “Um, prrf, sorry Xili. I thought…”

“You could have just asked, jerk!” Xilimyth snapped her tail, yanking up the hem until half her boobs spilled out from underneath it for Brenda to see. “Do these look fake to you!? I need help in case it’s not…are you laughing!?”

“Sorry. Sorry!” Brenda had a hand on her muzzle, doing little to stifle the giggling ‘prrfs’ that escaped. “All those years of teasing ME about being a cow and look what happens to you overnight. Did you get into Desmond’s food again?”

“Sis, this is serious… oh, wait…” A far away stare overtook Xilimyth’s violet eyes. Memories flashed back to helping herself to an open carton of heavy cream before bed, only vaguely aware of the biohazard sticker on it. “Okay, odds are good he might be behind this, but is he even awake?”

“I sometimes wonder if he even sleeps. Want me to go get him? I can go fetch my milker while we’re at it? Hee!”

“Bren! Come on, this is… is… o-oh! Oh, gosh!” Xilimyth’s tail gave another hard snap, a shiver racing through her hips up into rippling mammaries. She dropped the shirt back over them but it did nothing to ease tightening in their overstretched furry skin. “Aaaah! B-Brenda h-help! It’s happening agaaaEEEENNNGGGHHH!!”

BWOOSH!

Brenda’s eyes bulged out of their sockets in slack-jawed awe. With one thunderous slosh her sisters new assets inflated out into a shelf you could set dinner on. The shirt specifically designed for dealing with breasts overloaded with milk was drawn tense in seconds. Red fabric perfectly defining the round mounds as boulders even a cougars thick muscles might have trouble carrying.

It was hard for Brenda not to feel a pang of jealousy at having her bust size surpassed in less than three seconds. All of Xilimyth’s upper body was now hidden behind a bouncing blanket of milk glands, spanning much wider than her shoulders and hips. Amazingly, they remained firm enough to keep all that upturned flesh hanging above her belly button. The shirt had quickly reached its limit, however, allowing a bit of under boob to falling out of the hem.

“Gah!” Xilimyth coughed, resting hands best she could on either side of her spacious breasts. Brenda did not need to ask what next, as she could also see the tubs of jugs ripple like soft waves under their covering. The round spheres inched ever bigger, causing strands to groan until light tears began forming.

“Prrf! Don’t tell me…”

“Ah, I… I can’t stop it!”

And so even Brenda’s legendary shirt failed to contain Xilimyth’s unstoppable growth. The cheetah tried hugging her mounds, unable to even connect her hands around them, but it did not help. One tear after another opened up, allowing tender tufts of boob to bulge out.

Brenda’s tail smacked against the door, upset her sister had not thought to just remove her favorite emergency garment. She did not get a chance to even voice the concern before it broke under the mounting strain.

A large split formed at the hem, rending the front in a dramatically loud unveiling of Xilimyth’s cleavage. She responded with a yelp, trying to hold the bottom halves together, which forced her rising mounds to surge out the opening squeezed together. Pressure mounted with increasing speed, causing her arm muscles to bulge, trying to hold the shirt in place. It was a battle Xilimyth knew she would not win, but kept up the fight all the way until she lost her grip.

The one thing neither cat expected was for the cotton to be under such pressure that both halves of Brenda’s torn shirt sprung back to smack Xilimyth in the face.

“NYAAH!?” Xilimyth staggered back seeing a white blur until her butt smooshed into the counter. Freed hands quickly reached back to brace against the hard bouncing of heavy wrecking balls. Her buff legs could barely support the weights with each drop yanking on her chest. God the sloshing became an audible rumble at this size. No wait, that was something behind the shifting liquids. “Brenda, look out!”

"… oh!”

Brenda only had enough time to process her sisters warning before a wall of white fur slammed into her front. It may have been softer than any pillow the cougar had ever experienced, but its plush consistency also allowed her no way to grip or push against it. The ever rolling blob of tits shoved the cougar onto her back where it quickly oozed across their muscular curvy form.

Xilimyth gasped as her breasts resumed growing without end this time. Before long all she could see was a rising crest of snowy white cleavage pushing into the ceiling. From somewhere directly in front came her sister's final cry before succumbing to the onslaught of boob blankets. At least she could still feel Brenda squirming under the inflating mounds. It was almost a bit of a turn on.

To say the cheetah was going through another growth spurt did not do it justice. Xilimyth felt more like someone had attached her chest to a hydrant before breaking the valve in an on position. Within a minute her girls had already filled the bathroom, squishing into the bathtub and bulging to get out the doorway.

“Brenda!? D-Dessy? Somebody help!” Xilimyth squeaked as the pushback forced her onto the sink counter. Her wings pressed against the mirror, increasing its damaged cracks. Ears folded back, unable to take all the groaning and gushing noises echoing from inside her teats. Odds were good her roommate could not save her from being crushed by her own boobs, even if they were awake.

A loud crash made Xilimyth cry out for fear of the end. Instead, her ears perked back up, confused that the pressure had released. The fact the bathroom no longer had two of its four walls quickly explained that.

“Oh crap! Oh crap! Oh, crap!” Xilimyth tried to move, but that was pointless with two literal hills of fat spawning from your pectorals. And still her growth pushed them into the hallway, across the laundry room, where ever their pliable form could find space to fill. When that became a problem, it was a simple matter of surging out until the house walls caved in. “The landlord is going to kill me for this. Oh god, don’t kill my friends either, you damn wild boobs!”

All Xilimyth got in response was one crash after another. A shattering from the living room alerted her to the destruction of the glass case that displayed her anime figures in. Some metallic crunches signaled the end of their video game center. Her boobs must have reached the garage at some point, because there was a lot of loud popping and crunches before a gust of air soothed the soft fur.

There was an amazing lack of pain for having one’s breasts imploding out of a house. Not that Xilimyth could complain in her trapped position. Cheetahs are just made of naturally sturdy material. If only the same was true about plaster and drywall.

“Ack!?“ Dust rained upon Xilimyth’s little pink nose, making her cringe with a snort. She followed its trail upwards to a sight of shattering ceiling that made her ears slam back against her head. “Oh, shiiiii… "

What few support the house still had gave out under the relentless growth of cheetah tits. While the twenty foot high mountains of milk containers were relatively fine, the remaining bit of house against Xilimyth’s back gave way. There was only time to give out a scream as debris rained down upon her until all was black.

“PRRF! Whoa! Xili? Hey, calm down!”

“Wha-wha-HUH!?” It took a few seconds of screaming and thrashing before Xilimyth realized she was not dead. More importantly, was the fact she laid on her back in bed once more. The ceiling looked to be still intact, although the smiling snout of Brenda’s face blocked the view. “Brenda? You’re okay! And I didn’t smash the house with my boobs!?”

“Wow, you really were having a bad dream with all that squirming. Take it slow, nee-chan. You took a pretty bad hit.”

“A dream…” Xilimyth flopped back against her pillow with a sigh. Relief had never felt so good as this. “Of course it was all a silly dream. Guess that means I didn’t outgrow your favorite… shirt?!”

Brenda watched her sister try to sit up only to immediately meat with some very hefty resistance. It was a little funny watching the gears turn behind Xilimyth’s eyes as they looked over the crest of medicine ball sized breasts to the bloated pink nipples capping them. Their thick span could almost double as a blanket poured to rest over her toned stomach like that. “Oh, you prrfing broke my favorite shirt all right. It gave you a damn concussion as a thank you present too. We’re just lucky you stopped after that. You haven’t had any more spurts all morning. Not that we need you getting any more bigger than me.”

“Oh, shush! It’s not like I planned this,” Xilimyth grumbled, pushing into a sitting position. The hang of her new breasts flopped right into her lap and sagged across her thighs. So the growth happened until the point her fears of never stopping took over. That made a little sense, along with being a minor relief. At least they still had a house. Passing hands along the outer shoulder exceeding girth caused her tail to twitch. Their weight was not so bad after a while either.

“You okay, Xili?”

Before Xilimyth could form an answer, the bedroom door swung open, allowing the blue squirrel form of Desmond to poke his head in.

“Morning girls! Did one of you drink my creamer last night? It was a sample from a monster cow experiment Janus… oh…”

“Yeah, oh!” Xilimyth huffed to mask her budding approval of the jiggling mammaries her second roommate had stopped mid-thought to ogle. “I should have known this was your crazy shenanigans again. You owe me some new bras.”

“And I want a new milky shirt!” Brenda pipped in.

Desmond looked between the two felines, though his eyes never lifted above their collarbones. When he was clearly sizing them, Brenda offered a soft warning hiss that jumped him back into reality. “Hey! We agreed my stuff is on the bottom shelf. You tall gals got no business foraging down there.”

“Don’t care, Xili want bras!” Xilimyth crossed her arms letting them squish low into the soft cleavage she now sported. Yeah, these definitely felt a lot nicer than onlookers might think. “Sis, I’m still a bit woozy from the brain damage. Can you go take Dessy shopping for us?”

“Sure,” Brenda said as she stomped towards the squirrel-filled doorway. "I’ll call work and let them know you‘re… sick today.”

“Wait, you two can’t just decide…”

Brenda gave little care for Desmond’s protest, grabbing the much smaller male to drag him out by his tail. Xilimyth could still hear a struggle for a little ways until she caught the slamming of the garage door. With that little business done, she lowered onto her back with a heavy sigh. Hopefully, the headache caused by Brenda’s shirt breaking went away soon.

At least there were some awesome tits to stroke in the meantime. That quickly helped alleviate a lot of Xilimyth’s discomfort.
