^When you take a look at the earliest pictures of Beshine, she appears quite slim, even her hips and thighs, however, I would speculate the increased size/musculature of her body is completely secondary to the manner she has had to adopt to handle the breast size/weight. My picture post today sheds light on the issue; Beshine is far less likely to simply bend over like any of us would do, but as you see in the picture, incorporates a bending with a squatting to reach a similar level. This is required to maintain increased balance, as well as decrease back stress. From bending to sitting, to the full squat Beshine does to reach things on a low level, this is going to increase musculature considerably when performed more than 100 times on the average day and her legs show the result.
Another interesting thing about the photo is that the degree of bending and squatting is likely limited because her breasts are now pressing on her thighs. We see this whenever she leans forward slightly when sitting or squatting, and when she wants to lean further forward, she must lift her breasts up as she leans and put them lower on her thighs. Just more adaptions to immense breast size that Beshine does deftly multiple times every day. While each may seem a chore, my bet is Beshine loves the fact that she has to perform all these measures.
