Hmm I thought I respnded to this topic before but I guess I didn't. My earliest BE memory was discussing it with my best friend. It was like, 1991 and I was five years old. Thats about the time my mom got pregnant so maybe I subconciously noticed her enlarged body and the rest followed suit.
I think the BE part began to take hold after watching thumbelina. Ahh yes, that movie came out in 1994 and thats when I moved from indiana to california. 3rd or 4th grade I think...there was a gal who developed small breasts ( well they looked huge to me at the time) and I rememeber hoping that all the other gals in class would grow breasts as well.
Anyways about thumbelina, theres a song
and the female frog has a decent rack. I think her plump breasts combined with the way that frogs naturally puff out their throats in a sort of real-time expansion scene is what crossed my wires and laid the seeds of my BE fascination.
Frogs grow + I like breasts= I like when breasts grow.
