Captain Birdseye sure was on to a good thing when he invented the Birdseye view (that may not be factually correct), as it possibly one of the best ways to enjoy and admire an exceptionally excessive bust!
Indeed, Gate Fifteen is one of the many great places to work at the Research & Testing Facility (see BrasByDesign - Lore, The Universe and (Almost) Everything), giving one a fantastic vantage point with which to observe the comings and goings of the many subjects. There are larger gates, of course, but examples like Gate Fifteen can cater for well-endowed women almost twice the size of Melanie here - that is, assuming they pay attention and open both of the gates!
It is almost impossible to stress just how enormous the Research & Testing Facilities are - a seemingly endless rabbit warren of corridors and passageways, connecting a mind-boggling array of facilities such as Staff and Subject Quarters, Laboratories, Offices, Leisure and Wellbeing provisions as well as those all important Treatment Suites, to name but a few. If you need something or someone, you can probably find it, somewhere!
Admittedly, as Melanie aknowledges, the transference procedure could be a touch more flattering. Being refered to as 'Over-Size' doesn't do much to help a girl feel slender and dainty, it must be said. Then again, she's been here long enough to know that it is nothing personal - just internal formalities - and Nurse Louanne has done a great job of attending to her every need since Melanie arrived here some 18 months or so ago, when she was first accepted as a research volunteer.
As for the operators at Gate Fifteen? Well, in fairness, if you saw a girl like Melanie heading your way, her enormous bra stuffed and straining as she jostled with the 'Parade Straps'* and attempted to maintain momentum, then you'd be pretty distracted too, right?
