The sight of the plump, juicy cleavage peeping out from beneath her T-shirt, restrained by the huge, heaving cups of that enormous Bra is quite the sight to behold.
In the original Sketch I talk about the fantastic aesthetic of a very well-endowed woman needing to often wear over-size clothing in order to simply find something that fits the largest part of her figure. What makes it even more beautiful is when a garment several sizes larger than the wearer really needs still doesn't fit - in this case exposing almost all of that glorious, enormous soft-cup Bra, with that burgeoning swell of cleavage peeping shyly from beneath the billowing tent of vibrant fabric. It is an exquisite look, in my opinion.
There is also the charming irony of the Bra being nude in colour; I have talked about it before, but the idea behind a nude bra (or beige as it now known, as one skin tone certainly doesn't fit all) is that it blends in easier behind clothing, especially if you are wearing something light, such as a thin white blouse or dress. The idea of a nude Bra at this size seems to take the word 'subtlety' and then let off an air-horn in its face. Of course, the other qualities of a traditional Bra also have their charms too, such as the fine lace upper-cup panels that, if you look carefully, allow you to get a glimpse of Bella's huge, stretched areolas beneath the taught, opaque fabic. Bella has at least tried to maintain her modesty somewhat, and who knows, perhaps it has been a while since she last wore that T-shirt and she's 'developed' a little more since then? At this size, being covered up 'about enough' is probably as good as she can hope for!
As for Buttons, well, you can't blame a Dog for wanting to find a cool, shady spot on a warm day, and I can probably guarentee that there is no shadier spot in the entire park than underneath that vast, glorious Boob-shelf! Perhaps some kind, helpful passer-by could help her find him, and maybe buy them both a cool drink of water? I'm sure Bella would be incredibly grateful...
