I have to admit, I love big breasts. I'd prefer (selfishly, I know) that chicks put implants in if they are under a B cup, maybe even smaller than C. I'd rather have nice looking fake ones than mosquito bites. Again, I admit my experience in this area is limited due to the fact the string of ladies I enjoyed before my wife were all well endowed and none were fake.
I think the best breasts are D's.
