I understand that the desire to have boobs this enormous is because of the feelings they create. It isn't some sort of body dysmorphia as most would suggest, but to those with boobie greed, there is a sexual component to feeling overwhelmed by the size of their boobs that leaves them wanting more. In this video, after having to lift her boobs to place them further down her thighs to enable her to lean forward, there is an expression of lust on her face, something I have noticed in other videos also after looking at her breasts for more than a few seconds.
Beshine's happiness in not really despite the burden, but the burden adds to her happiness and is the reason she always says how much she loves to experience her "massive boobie adventures." I truly believe that the main reason she has continued OF is because she loves how she looks in the camera and how she looks in clothes she would not wear in public because of the attention they would draw. As time went on and she made her boobies bigger and bigger, we saw her regular site content strayed increasingly further from public view; she doesn't seek public attention, the reason she has made her boobs this enormous is because of how they make her feel.
