Most girls would never want boos so enormous that they impeded normal movements and made daily life very different and filled with enormous boobie problems, but I believe Foxy would welcome the chance.
Well, I think there might be a lot of women around which have a deep curiosity of what it might be to have bigger or huge boobs and doing all day things in different ways with all the limitations and adaptions and the joy they bring, but don't want this to be permanent, not only for health reasons but maybe of social impact.
I totally agree, both the physical difficulties and limitations increase with size and weight, while the social isolation to a significant degree is something many would find not accept. You have to have the attitude that you want to experience the boobie problems because they draw your attention to the size of your boobs, which is a positive affirmation because just the sight of them pleases you. And obviously, you need someone in your life willing to do all the things you now find too difficult. The socialization takes a particular mindset that Beshine described very well; friends that could not accept her new look were no longer friends and the opinions of people that are not her friends doesn't matter. In essence, she has her family and a tight network of friends that realize that choosing to have enormous boobs did not changed who she was.
Of course, I think Foxy is far more outgoing, accepting the attention enormous boobs would cause. Having gotten to 10k, she is well aware of many limitations, however, if she has the surgeries she wants, the combination of boobs mounted much higher on her chest and larger implants will open a whole new world of huge boobie problems for her, a world I think she would love.
