I agree, if she were after financial gain, she would be flaunting herself publicly and on social media to attract attention; she does neither in a way to attract followers. I have to assume that though she absolutely loves not only having enormous boobs, but all her enormous boobie adventures daily, that she has little outlet to share these things as anyone close is already acutely aware of both. Thus, for the few of us that find her, her massive boobs, and her daily struggles fascinating, she has a private place on OF where such things are welcome and she is happy to be able to talk about and show off the things she loves.
I think her motivation for the future rides with how proud she is of her huge boobs. Having already stated that once she fills her implants to their designed capacity, she will replace the saline with a liquid that will soon form a silicone like gel to make her boobs permanent and decrease the risk of a leak. Just the fact that she want to live her entire life with such huge and heavy boobs should speak volumes as to the pleasure she derives from having them.
That picture from Thursday is really something, essentially demonstrating the limit of sitting forward, her boobs, like huge balls pressing against her chest and thighs simultaneously, preventing further movement. And her description always displays her delight; "And here's a brand new clip that goes with the picture from yesterday, August 8th. WOW... the vast dimensions of my huge massive boobs are so infinite that they not only take up my whole upper body and beyond, but also my whole thighs when I rest my gigantic breasts on them. PUUUHH... the immense weight is A LOT, so I can only sit like this for a short time."
When you look at this and similar pictures, you get the idea that for many months of her pregnancy, she could not sit at all, but must have had to be reclined or laying down.
