Massaging your breasts, I'm assuming, is a form of jelqing, which is done in many cultures by men, since the beginning of time, to increase the size of their member. I have a friend who was rebounding (using a mini trampoline) as exercise and claimed that her bust was increasing in size. This is the first thing I thought of.
