Would love to hear your thoughts. <3


It all started on another routine Wednesday afternoon. That was the day supermarket coupons and sales changed over, allowing new opportunities for savings and dinner options. A certain trio of roommates needed ample amounts of both, with the amount of calories they collectively consumed. For two it was a byproduct of sporting ample amounts of muscle on their even more ample feminine curves. Vigorous gym workouts required lots of fuel.

Their third party just somehow consumed food without recourse to his scrawny physique.

Point being weekly shopping had become something of a regular part of life since their move in together. Brenna, a she-hulk level of cougar woman, had drawn the short straw, but Xilimyth had no qualms tagging along. Their lithe cheetah body had an easier time snagging things on the lower shelves, while a chance for some outside interaction was always welcome.

"I'm thinking lasagna tonight," Xilimyth mused while her cougar sister eyed an end-cap of bagels. "Look at all this discount sausage. Dessy likes sausage, right?"

"Prrf if I know. That guy is a vacuum when it comes to food." Three packs of blueberry bagels fell into the cart before Brenna maneuvered to grip the drive handle. "It's easier to make a list of things he WON'T eat, honestly. The spicey stuff might be a bit much, though, ni-chan."

"Oh, he'll be fine with this level." Xilimyth placed several packs of ground pork and beef in with their small collection of food items. "Spice is good for his heart metabolism."

Brenna gave a look suggesting concern for her own taste buds safety with Desmond's. Her cheetah sister had a fireproof stomach that sometimes affected how much seasoning went into their dishes. A bag of hatch peppers already sat amid their rations. On the other paw hand, thinking about a hearty pasta dish set the cougars muzzle drooling. "I'll go see about some garlic bread and salads, if you want to grab noodles and meet up later."

"Sounds like a plan, pomf!" Xilimyth wiggled her draconic wings in gleeful skips towards the nearby aisles. "I can grab some toilet paper too. I'm pretty sure Dessy said we were out."

"Oh, he better not have used the last roll, that lazy prrf!" Brenna wrinkled her nose but her sister was already too far away to vent annoyance.

She turned back to observe the meat freezer again, only to notice a badger had stopped midway pulling out a sack of burger patties to ogle the cougars chest. The medicine ball mammaries firmly stretched out Brenna's into a spacious shelf, distorting the 'PAC' stitched on its front. Their hang was just enough to rest upon her knuckles holding the shopping carts handle.

A deep rumbling cough from behind Brenna's power chest muscles proved enough to snap the dazed man from his trance, along with drawing attention from two other shoppers. His eyes immediately shot up to meet her furrowed brow glare, dropping the heavy bag of frozen beef on his foot in his confusion. Watching him stagger in a flustered pain quickly deflated any agitation Brenna had left. It even got her to smile a bit.

"Dairy is the next section over if you're that thirsty for it," she quipped, driving the cart off with a whip of her tail.

"Oh, uh, t-thanks," was all the embarrassed man could offer.

Brenna was blushing too hard herself to be hard on him. It's not like she entered society to eat up the attention her bulking curves drew. Once she met back up with Xilimyth, they could both retreat to the comfort of gamer isolation before any more awkwardness happened.

Not twenty feet away, attempting to collect pasta noodles, the lithe cheetah stopped in place to give a small sneeze. She blew her nose with a pocket tissue, only to grunt at a sudden pressure pinching both shoulders.

"Goddess curse you, lovelies," she grumbled with a backward glance at fluttering dragon wings. As much as she loved having them, bra fashion was still a decade behind in designs. Her sudden jolt from the sneeze completely displaced the undergarment, forcing her to dig underneath and redo the clasp.

"Um... what?" Xilimyth's tail rocked in perked confusion. Somehow re-locking the straps only made things worse, now harshly squishing breasts against her ribcage. A glance down had her gasping to find her modest C's had ballooned into a more E-cup range. The expanding shelf hefted up her shirt hem by several inches, exposing her toned midriff. It's formerly snug fit quickly grew taut, wrapping the growing mounds tight enough to see their now undersized bra outlined in the fabric.

"Oh, fuck no!" Xilimyth's tail whipped the ground with fur rising on ends. She dropped the packages of dried lasagna noodles to hug at her chest. Not that such an act ever stopped their growth spurts. The fatty milk balls continued to push back against her, puffing out excess over her forearms in their steady march through conventional bra sizes. "I'm not growing now. Not here! I'd have to pay for this stuff! Nya-haaah!!"

In defiance of her own wishes, Xilimyth's body staggered back against the aisle shelves, surging larger in overall size. There was a dizzying rush of vertigo with suddenly becoming eight inches taller. The gap between shirt hem and waistband stretched even wider, unveiling the white fluff of her stomach. Said waistband slipped lower with the push of her thickening hips and buttocks. Despite that, pant legs creeped halfway up her shins exposing FATE ZERO socks.

Glass shattering filled the air, complimenting the cheetahs string of curses. Her growth spurt and subsequent larger tail were shaking jars of pasta sauces off every shelf level. This drew many unwanted shoppers and store worker's attention, several arriving at both end caps in time to watch a rather tall and voluptuous cat woman in comically small clothes struggling to get her bra undone. Xilimyth's tits began resembling the size and curve of very large melons, which drew the straps too tight to get any slack out of them. It took several pricks with her claws to cut them with a stinging snap across broadening shoulders.

"Ah damn it," Xilimyth heaved a relieved sigh even as her growing bust bounced hard in its sudden freedom. Her shirt was already running out of room with their bottoms pushing the loosened bra cups out from under its rim. Attempts to tug it back over them only cause a snap back against her blushing face. More people were gathering, forcing Xilimyth to leveling back onto her tight-shoed feet. "E-everyone of you guys should probably make for the exits. I... I will probably get a heck of a lot bigger than... ack! Right on cue!"

Another growth spurt struck, sending the cheetah careening into the opposite shelf. Knees wobbled as growing legs widened their stance. Hands raced in opposite directions, sending packages of dried pasta collecting under her rising frame. Ears folded back, not from the tension of bulking muscles, but from the loud tear that echoed behind her. A cold breeze of conditioned air under her raised tail was all Xilimyth needed to know her jeans had split.

More soft tears followed until a tingling caress across her legs told Xilimyth her jeans had fallen apart. The panties underneath put up a much grander fight, which proved to not be a good thing. Fat and muscles were rapidly expanding the cheetahs pelvis, causing her cheeks to swallow the fabric until they were barely visible. Nothing killed a good growth like a damn wedgie. The only thing worse was the painful pinch in her shoes.

SHHRTT!!

Well, okay, so much for shoes. Xilimyth's toes exploded out the front of their synthetic covering, splaying across the cold concrete floor. While she appreciated the respite it also brought the crushing realization her claws had destroyed her favorite anime socks. It was hard to see over the increasing roundness of her bust and hips, but the cheetah could feel the shredded wool tightly wrapped around her enlarging ankles.

"Hrrp!?"

It would have been nice for Xilimyth's shirt to have died in such an easy fashion. Each addition inch her breasts fell forward only drove the tight hem up to expose their tender soft flesh. No sooner had it reached her puffing nipples than what remained of her milky mounds fell out with an audible slosh. Instead of tearing, the rapid body expansion drove it up into a cluster around her neck and shoulders.

That would not have been such a problem if said neck and shoulder were not plumping up several times meatier like most of Xilimyth's muscles. While her breasts squished progressively harder across three shelves at once, the feline gal grappled against the choking shirt collar. It was only thanks to her progressing power that she could eventually rend the entire shirt from her body.

"Having fun, nee-chan?"

"Eep!" Xilimyth jolted out of her frantic shifting, noticing she towered over the aisle around fifteen feet tall. Hands clasping at the tops easily bent slight grooves into the metal tops trying to grip them for balance. Breasts rolled between her arms over the surface, eager to hang over the next lane for dumbstruck shoppers to admire. Each mound was already bigger than the cheetah's bulking torso, threatening to crush bystanders that admired her manhole sized areolas too long.

Brenna was not so easily intimidated, even well knowing those boulder boobs would to get a heck of a lot bigger soon. But what timing the buff cougar had to be collecting potato chips the next aisle over when her fuzzy ears picked up the familiar sounds of a cat in growth. That's one way to spice up an afternoon.

Xilimyth slinked back, trying to hide her blushing face behind the jumbo span of her bust. She forced a helpless grin, looking through the space between breasts. "Oh, you know, pomf, business as usual. C-can't really stop it eith-yeek!"

Panties chose that moment to lose their prolonged battle, slicing through the crack of Xilimyth's butt in a rubber band style flossing before joining the other shredded clothes between feet bigger than shopping carts. Tail and wings gave a reactionary shudder which sent the entire shelf of behind her toppling over. She sunk even further behind the loom of her breasts as loud crashes, shrieks, and shattering filled the store. If anyone had not noticed the twenty foot cat girl by now, that certainly announced her presence.

"So, what the prrf happened this time?" Brenna asked with an air of calm patience. Neither of them were the type of cat to demolish a grocery store at random, but fate made sure they achieved this feat on a disturbingly regular basis. "You try a free sample from a wizard or something? I swear I can't leave you alone for two prrfing minutes."

"I didn't do anything I swear!" Xilimyth giggled despite her naked figure continuing to stretch up and outward. The strain of her sinew strengthening on growing bones was a regular background noise for Brenna's twitching ears. "I was getting the noodles and just... started blowing up. Five bucks says Desmond has something to do with this?"

It was Brenna's turn to laugh. "I know he's responsible for, prrf, a third of our 'accidents,' but the last thing I remember happening between you two was yesterday when you took his last muffin."

"Hmph!" The cheetah's blunt muzzle twisted into an adorably grumpy face that belied her intimidatingly swollen body strength. "I was late for work and hungry. He knows better than to leave snacks out unmarked."

"Neechan, I admire your bravery to still accept anything that man cooks."

"He's not that bad a cook. Besides, I can't think of anything... ooooh!" Xilimyth's giant body stiffened, except for her breasts which emitted an ominous rumble from deep within that sent them rippling like water. She bit her lower lip, metal straining from her tightening grip on the store shelf until knuckles turned red. "I, um, I got to go, sis. Big spurt building up!"

"Yeah. Yeah." Brenna could not help smirking with her eye roll. Without a glance back, the cougar resumed pushing her cart towards the checkout. "I'll see you at home. Don't make a mess."

"Nyaa-aaah!" Xilimyth would have made some bad pun to counter Brenna's parting line, but the jolt rushing through her spine overloaded every pleasure senses. Wings jutted out in a full stretch, knocking an additional aisle over while hips undulated against the shelf she was using as a brace. It only lasted a few more seconds before yielding to the power of her rippling biceps, snapping in three sections, with the middle one becoming crushed under the chetah's swelling tits.

"Ah, fuck yeeeeah!" Xilimyth arched her back in a delighted cry. In the felines experience, which Brenna might reluctantly confirm, the big spurts were always the best ones. Every muscle, every cell, of their body contracted and exploded several times in size, sometimes not in sync but always in such drastic amounts that it triggered equally large doses of sensual hormones. As her head raced towards the ceiling, everyone could better see Xilimyth's stomach rise over the shelf glistening with sweaty fur around the ridges of hardened abs. Not far behind it was a woman's crotch, puffy and wet for very different reasons.

She was just glad Brenna was long gone with most of the other shoppers by the time her towering frame began plowing through aisles. When these cats went big, they brought a lot of collateral with them. It was worth noting, however, that they grew in slightly different ways.

For Xilimyth, muscles were actually the third runner in this race. While her powerful thighs could crush watermelons, it was the involuntary flexing of her glutes that drew the cheetahs gaze over her shoulders. The hump of her backside bounced rigorously with each rapid flex. As the seconds passed plump, fatty cheeks only puffed further out behind her adding heft to her rapidly wagging tail.

And that bodacious butt was still nothing compared to the breasts casting dark shadows under the scattered package beneath Xilimyth. Each hand reached down, stroking the underside of weighty mound big enough to smash cars. She hefted them up and let the pliable weight pour through her fingers to bounce with a 'boing' sound that resonated into the parking lot. Despite being the biggest part of her, there was nothing but pleasure with the motions. The strength of her pecs behind such boulder sized tits easily carried their weight, allowing her to repeat the heft and drop several times to pleasured mews.

"ACK!" At least Xilimyth could enjoy herself until the rapid increase of her height eventually brought her head crashing into the stores ceiling. Ears folded back with her foreheads continued grind against the plaster and metal, filling her purple hair with raining debris. She especially did not like it when the nearby speakers crackled into the big round discs.

"Attention shoppers and associates; we have a class-two macro incident in progress. Please evacuate in a calm and orderly fashion. Walmart is not responsible for any death or injury incurred from stopping to take pictures."

"Yeah, I'll have plenty of time for that outside," Xilimyth booming voice added, along with purring giggles. She considered dropping onto knees to give people a bit more time to leave, but another jolt surged through her spine, eliciting a yelp. The quarter mile cheetah tail cracked against the floor, shattering a shallow trench into it. Her body rumbled, pressing forehead deeper into the straining overhead until the walls shook with her. "Ugh! Speaking of which, I hope management doesn't ban us for this next surge."

In a comfy house a few miles away, Desmond was feeling pretty satisfied with himself. The kitchen sat perfectly cleaned with a fresh load of dishes set and ready for Xilimyth's use. It was an unspoken deal they had made at some point that of the cheetah made food the blue squirrel-fox needed to do the cleaning. A reward his bottomless stomach would go through hell for.

Now with that hard work done, the cats third roommate flopped his big fluffy tail into their couch ready for restful rounds of Monster Hunter. A black furred hand reached out for the TV remote, only to have it slide away with a gentle rumbling.

"The frick?" Desmond perked his pointed ears as another vibration shook the walls and everything attached, followed by another. It was certainly not an earthquake. He straightened out to count them, each arriving around three to five seconds apart. Some kind of rhythm that, the more he thought about, the lower his tail sagged until it lay limp across the cushions. "It can't be footsteps. Not on Lasagna night!"

Desmond snatched up the dancing remote, turning the TV to the first news channel he could think of. A slight groan escaped his lengthy fox muzzle, not surprised to see a cheetah woman going for a stroll on live camera. It went without saying that being naked and forty-some feet tall was what made her excursion worth of breaking news. Their muscular figure and thick curves cast a wide shadow across nearby buildings, especially with mile long dragon wings. Or maybe it was the zeppelins she had for boobs bouncing so hard they made clouds part with the shock waves.

It was with this discovery that Desmond noticed the vibrations not only synced with TV Xilimyth's footsteps but also became stronger with each step. Throwing the remote down, he rose onto large pawed feet expecting to get a tongue lashing for this latest development. Like those hulking felines did not have plenty of 'accidents' before a mad scientist moved in with them.

"I hope she remembered the toilet paper, at least."
