Rene shifted from foot to foot as she anxiously awaited the reveal of the customer she was currently attending in the changing rooms. This job was a treat for the koala in more ways than one; Not only did her own hefty body shape fit in with the store's merchandise, but she got the chance to admire even more generously bodied women up close and in a variety of form-fitting outfits. Even now her mind raced with fantasies of her current customer buttoning up a blouse, soft belly being squished this way and that in the process, all mere feet from her! It was enough for a girl to make a few stains on the carpet, which she admittedly had done so before, more than once.

"Excuse me, dear, do you have this in a larger size?" asked a voice from over the changing room door. "Which one?" replied Rene. In response, the door opened, and out waddled one portly Pidgeot. The bird woman was notably taller than the bear that attended her, and weighed more than double easily, but it was her bust that truly blew the smaller woman out of the water. Those twin cream-coloured mounds were currently compacted in a vest that barely had two out of two dozen buttons done up, the valley of cleavage threatening to fall out of the garment at any moment. "It's not that it's uncomfortable, but I was wanting to wear it to work and I can't rightly go like this!"

Rene had seen many busts of various shapes and sizes, the latter of those qualities almost always on the "huge" end of the spectrum, but Rosa's rack being squashed together like that combined with her feathers made Rene feel like if she fell in, she'd never find a way out of that softness. "Sorry, hun, that's the biggest we've got in your class. Maybe another set of hands can help..." she said before firmly pushing the Pidgeot back into the changing room, locking the latch behind her with practiced skill.

The koala girl made something of a show of trying to stuff those jugs into the vest, the bird's flustered sounds stifling her question on how she'd be able to button it up on her own once she'd bought it. After several minutes of effort, the koala stopped. "Seems your girls really don't want to cooperate. But then, we both know that even if it fit perfectly, you'd be back for a new one within the month~" said the koala with a smile. Rosa gulped nervously. "What makes you say that?" she asked, a hint of blush colouring her chubby face.

"Don't think I haven't noticed you waddling in here so often, your clothes threatening to tear right off you. Those clothes being ones you had bought the last time you were here..." As the bear talked, her hands never left the bird's breasts, moving in slow sensual circles on the exposed cleavage. "No one else seemed to notice. Seen one fatty looking for something that fit, seen them all, right? But I noticed. I never managed to snag you as my customer though. Not until now." Her hands circled downward, over the tight fabric of the vest until they reached the few buttons they had managed to do up. "I don't know what you have, but it's clear you're one of those women that just can't stop growing. Which is good, 'cause I can't get enough of you~"

At that last remark, the last button popped undone, eliciting a cute gasp from the Pidgeot as her heavy breasts fell free, naked as she had hoped foregoing a bra would give enough room for the vest to fit. She had remained silent, shivering a little in nervous excitement as the bear explained her admiration and undressed her. "I might have a problem with growing..." Rosa said meekly, the marsupial smiling as she nuzzled herself between her breasts, looking up at her, one hand raised to cradle and stroke the bird's chubby chin with her thumb and forefinger, "But I'm sure you've had customers larger than I am!"

You might not have been the largest I've had, but I have no doubt you will be~" With that, the hand that had been cradling her chin popped up, having concealed a small container of pills, a number of which tumbled into the bird's open beak. Taken completely off guard, Rosa tried to spit the things out, but in her initial surprise had accidentally swallowed some of them, others following in her desperate attempt to spit them out. "Ptha! Pthew! Ah! Wh-what did you just give me?!" she cried, holding her belly, the resting place and soon to be workplace of those pills. "A little something to help some girls when they're just a little off from filling out their ensemble. Given just one helps those clothes get wonderfully tight on them, I can't wait to see what they do to you!" answered the bear with a mischievous giggle.

As if on cue, Rosa's belly, followed by the rest of her, began to emit a low rumble, her already present rolls of fat jiggling a little even though she was standing still. "I didn't think they'd start that quick! Best get those pants off befo-" RRRRIIIIIIPPPP "Hee hee, too late it seems!" teased Rene as she herself undressed while bearing witness to Rosa's own "undressing".

The bird's modest belly spilled over the waistband of her jeans, the poor button straining for a few brave moments before snapping off, the zipper underneath it unzipping to give that gut more room to breathe. Rosa's sigh of relief was short lived as the legs of her pants suddenly grew painfully tight, with no weak button present to offer relief. Her drumsticks grew so wide and flabby that they tore right through the fabric, stray threads holding on and digging into her softening flesh until they too gave way, the sides of her pants "unzipping" much more forcefully, the growing mountain of woman spilling outwards in all directions with a loud FWUMP, but her journey was far from over.

While each of her thighs were swelling to surpass the size of her hips, her upper half was getting its own second puberty. Her proud breasts, now being properly groped and squeezed by the bear, seemed to surge with each gasp of air the Pidgeot took. As Rene squeezed those boobs, she'd hold them for a few moments until the flesh spilling through her fingers grew to the point she simply couldn't hold it any more, letting go only to repeat the process. "God, Rosa, you're amazing..." she said, looking up at her with half-lidded, lust-filled eyes. The bird was covering her fattening face with her softening hands, cheeks flush with embarrassment and arousal.

When she finally moved her hands from her eyes to behold herself, instead she got an eyeful of a soft koala crotch, poised and dripping over her thick beak. "I forgot, you're supposed to take those pills with water..." she said before her lower lips enveloped that beak, Rene's knees digging into the soft shoulders of the bird. "Ah, fuck, you're incredible, Rosa..." she panted as she rode her customer's face, biting her lip as she watched over the bird's shoulder as her ass swelled into a shelf she bet she could ride on it was so fat and perky. "You and, mmph, I both know that-ah-you were g-gonna get this b-big eventuaaahhhly...I'm just helping you get sexier...sooner..." the bear panted, her juices gushing out of her at such a rate Rosa feared she might drown. What she was unable to drink spilled over her fat cheeks, trickling between her multiplying fat folds.

The sleeves of fat that were enveloping her arms rolled back as Rosa brought her hands up to hold the bear's butt, keeping her steady while the bird dove her tongue into those needy nethers. Though she hadn't asked for the pills, she'd be lying if she said the effects didn't feel amazing. The bear's juices weren't the only ones dripping onto the floor after all! "I expect help...with picking an outfit...that shows all this off..." she said, looking up at Rene over the koala's own tubby belly. The smaller woman could barely stifle her cries of pleasure as her varied fantasies of Rosa ran through her head, knowing they could all come true now. "The outfits, the cleavage, the constant growth...it was all too much! Finally, with a scream all the other customers no doubt heard, she came, giving that expanded bird belly plenty to help it jiggle as Rosa gulped down all she could.

Her orgasm subsiding, Rene slipped down from her perch upon Rosa's shoulders, shivering as the bird's fat squished up between her thighs to rub her tingling snatch. "Mmm, I think you properly qualify for our Super Sized collection now~" she, rubbing proudly over that protruding belly the Pidgeot now sported, feeling it rise and fall with the bird's soft panting. "And I have just the thing for you to try on first!" Quickly putting on her own clothes, the koala dashed out and returned within the minute, a broad smile plastered on her face as she held up a sized-up vest identical to the one Rosa had been wanting at the start.

Though no matter how they tried, they could only get the first two buttons done up...~
