Will breast massage actually work for enlarging breasts?

Yes but only if you are diligent. You need to do it for ten minutes every day and concentrate on the nipples. They send signals to the pituitary gland to release the hormone prolactin. It tells the glands in your breasts to grow in prep to make milk. This can get you a 2 cup size increase but the hormone only stays in your body for a few hours so for best results you need to do it every 4 hours. Twice a day should help tho.
