There is a degree of difficulty in projecting the true size of Beshine's breasts on a girl as she goes about her routine. Clearly the weight and size tend to prohibit many normal movements and the speed in which they are done; Beshine does not or cannot perform typical arm movements, is reserved in bending, and slower and more deliberate in walking today than she was perhaps just a half dozen years ago. So inconspicuously imagining her breasts on others is not always as easy as it seems; there will be a boatload of movements that Beshine herself could not or would not make, but I have also done this before in idle time. Watching as a girl stands and imagining what she could not see right in front of her because her breasts block the view, what she could not reach because her boobs block most arm movements below her boobs, what her boobs would bump into if she bends forward, or how she would occupy a slightly confined space.
I have seen Beshine rest her elbows on her computer desk in the party chat, so clearly, with higher top tables, her breasts can project below them, but I have also watched her sit at a normal table and have to hike her boobs up over the table as she turns to face it; her perhaps 13 1/2" of projecting boobs then still pressing against the table. Sit at a table with your chest that far away; it is quite a setback from what would be normal. Her chair at the computer is likely without arms because her boob width could not fit between them and it would likely be uncomfortable pressing into her sideboobs. Just other observations as we imagine Beshine's breasts in casual situations.
Imagining Beshine using a shotglass to mix drinks, her arms essentially resting on her boobs as she reaches forward in the effort, clearly while amazing to watch, it would not be a job she could do well or quickly. But I have tried to imagine her doing other simple jobs, each presenting problems. Even as a check-out clerk scanning items at the grocery store; when you cannot simply slide a item at waist level from your right hand to your left because your boobs block not only that arm movement, but the item itself, that job is not for you. But it is always entertaining imagining the impossibilities.
