^Right you are; with her very high breasts encroaching and interfering with arm movements, they certainly can pose problems if you don't really like experiencing them. I do not know, but I have to imagine that she had an internal bra placed when she got her implants, with a certain volume in mind; when she expanded past that initial intention, her boobs, unable to expand downward, had to expand upward, giving her the extremely high look. Obviously, while Luna loves having big fake boobs, she is not in love with the limitations they have caused. It makes me wonder if she ever explored the alternative; lengthening the braided sutures that support an internal bra, thus allowing a natural lowering to occur; tiny incisions at each anchor point, no stitches necessary.
And you may be right regarding her husband's enthusiasm but he is always quick to lend his support of going bigger.
