Bust grows so slowly. I want a pair of cowtits on my shemale, but everything else is just growing so much faster...
My experience is that bust grows slowly at first but gets exponentially bigger as you invest into it.
You could mess with the scaling option. The default is 0.7 but you could drag that up to 1.0, which should make them a bit over 40% larger. Assuming the scaling is linear.
