Double-Door Cup Bra

"Knock Knock."

"Who's there?"

"Knock Knock."

Who's... Ah, I see..."

You  get the idea. Anyway, I was sketching away the other day, and it  occurred to me that at some point a 'DD' or Double D-cup could  potentially stand for 'Double Doors' instead. At least if you went  enough times around the alphabet, anyway - you can find out more about Extreme Bra Sizes in BrasByDesign - Lore, The Universe and (Almost) Everything of course. Maeve, our Super-Endowed, Strong-Backed heroine here is wearing a 28 DDx5-cup bra, and what a monster it is too! Although, it is already looking a little over-full...

Still,  double-door jokes aside, it is actually quite alarming that even the  increased dimensions of double doorway are starting to look only just  large enough to allow the rather over-boobed Maeve to pass without much  hindrance. How much longer before she's resigned to using the Over-Size  Fitting Entrance? Well, only time will tell, however, judging by our  bosom-ladened beauties keeness to just go a little larger, it might not be much of a wait!

You see, the Bras By Design  facility not only sets out to help and support those with excessive  involuntary breast growth, but it also works on developing its own  research, treatments and even growth methods - and these sensitive, and  sometimes dangerous formulas and contraptions need to be tested!

Maeve was just one such tester at this BrasByDesign  facility, and believe it or not she was barely a B-cup when she started  her testing career! The promise of good pay, inclusive accomodation and  a chance for her to gain those few extra cup-sizes she had always felt  she'd been missing, was an offer too good to pass up. But for Maeve, the  desire for just a little more never seemed to subside.  After her first few successful tests, Maeve was free to leave the  program as a hearty 28 F-cup - but instead, she signed up for further  tests. Lotions, Potions and Breast Expansion Machines, Maeve was happy  to enroll herself as often as was deemed safe. For reasons she didn't  understand, she just couldn't get enough.

As  weeks turned into months, and those months turned into a year, Maeve's  friends and family started to comment when she returned back home for  visits, alarmed by the ballooning bustline of their beloved. Her slight  figure lumbered with the excessive masses of flesh as they strained  behind tight bras and over-stretched, ill-fitting clothes. Maeve took no  notice though - her will was a strong, if not stronger, than her back.

Soon, it would be Maeve's friend's and family that came to visit her,  as she diligently, and perhaps slightly indulgently applied for further  tests and treatments. She blossomed, she swelled, she gained, and  almost exactly two years to the day that she started her testing career,  Maeve heaved herself toward the exit of the Fitting Room in a brand  new, gigantic 28DDx5 bra. Staggering and struggling with her enormous  bosoms, as she made her way through the doorway, the uptilted tips of  the taught, well-stuffed polyester cups brushed lightly against the  door-frame, turning Maeves face crimson. Her nipples tingled and fizzed  for a second from the unexpected stimulation, and then she giggled, "I  am most definitely a Double-Door Cup!"

Working at the BrasByDesign facility for so long now, however, Maeve was well aware that there was plenty of room to manouvre if needed. Day-to-day life was certainly becoming more challenging, for sure, but a few more cup sizes couldn't hurt, could they?...
