There's an old British idiom; 'You can't fit a quart into a pint pot' - meaning that no matter how hard you try, you can't fit something large into something small. Although, in truth, it's hard to call that bra small, there's definitely some wishful thinking going on if Ria believes she can squeeze all of that boob into it. Even if she did, the chances of it surviving anything more than the most gentle of manoeuvres is highly unlikely...
For a while, Ria actually believed her breasts were beginning to slow down from what was an unexpected and seemingly inexplicable growth spurt - though it felt more like a growth rampage. However, after popping and repairing her current bra three times in just one week, it confirmed once again that her puppies still had bigger plans.
Begrudgingly, Ria had to admit it was time for an upgrade, whether she liked it or not. The only trouble was, the upgrade path looked pretty bleak; even the local plus-cup store struggled to offer anything much larger than her old bra, and deliberately choosing a larger band size, in desperation, did little to improve the containment of Ria's huge swell of bosom.
"Are... are you okay in there?" the store assistant asked with timidity whilst knocking on the door of the changing cubicle, as Ria strained and struggled, mumbling to herself through gritted teeth. She pulled, she tugged, she squeezed and she stretched, until, finally her huge breasts fitted - well, of a fashion, at least. There were mounds of overspill beneath her arms, and a monstrous rise of plump, presurised cleavage that hadn't managed to find a home in the drum-tight polyester-mix fabric of those cavernous cups. The bra creaked and grumbled, but somehow, it held, and that would have to do! If it could have done, her old, patched up bra would have breathed a sigh of relief.
Once she'd settled her bill at the counter, Ria made her way to the bus stop across the street, softening her steps as best as her lumbering gait would allow in order to try and preserve her new and essential purchase. She felt enourmous, as her heaving bust stretched out before her, jostling and swaying beneath an extremely oversized and still, somehow, barely adequate old T-shirt.
The bus ride home was no better - every bump and pothole in the road made Ria's anxiety spike, as the frabic struggled to contain her swells, and the straps groaned under the sudden loads imposed upon them. Trying to take her mind off of the bizarrely perilous journey, she looked out of the window and clenched her jaw - she was only a few stops away.
Almost home, Ria stepped urgently off of the bus, and that's when she heard, and felt it - an almighty snap as both straps simultaneously popped - causing her whole bust to slip forward and down under the wickedly oversized T-shirt, such was the pressure of her breasts within the bra. Were it not for the bus stop sign to grab on to, the sheer weight and momentum of her huge boobs would have pulled her to the ground. Thankfully, the street was somewhat quiet, as Ria gathered herself and walked the half-block back to her home, struggling to cradle her misbehaving breasts in her arms, her nipples poking cheekily through the worn cotton. Naturally, she recieived one or two honks from over-enthusiastic car horns, but other than some mild humilation, she eventually made it.
Ria's old bra had lasted over a month, yet this one hadn't even made it back from the shop. Sure, she could fix it - for now - but things were starting to get real serious...
