Just being curious instantbust

The penis contains a sort of tissue that expands by pumping additional blood into it. Breasts don't have that tissue, but if you've ever gotten a serious bruise or broken something I'm sure you can understand how inflammation of the tissue surrounding the injury can make it look larger (i.e. break your thumb and the whole thing swells and looks noticeably larger).

I've seen ads for products like the one mentioned above, and usually they only promise an increase of 1/2 to 1-1/2 cup sizes TEMPORARILY. Never permanent. The concept that they rationalize it with (increasing blood flow and vascular dilation in the affected area) is at least conceptually feasible to produce the advertised effects. Whether or not it's anatomically/biologically possible to produce that sort of effect with a topical cream I don't know.
