Massage does *not* do that at all.
Stop searching for bigger boobs *now* before you get yourself into an unrealistic obsession about breast enlargement.
Your breasts are whatever size they are. That's not too big, it's not too small... it's exactly right - for *you*... for now. They'll grow over time - perhaps until you're 23 or 24 years old.
Just like every other part of your body, the shapes and sizes of your breasts throughout your life were decided the moment you were conceived - 9 months before you were born - so don't waste your time, energy or money worrying over them or trying to make them different.
There are only three ways you can get nature to do that job for you without surgery: grow to full adulthood, gain a lot of weight, or get pregnant.
That's *it*, and there's nothing else on earth that will work. No pills, supplements, creams, foods, exercises... nothing - not even a boyfriend. (although gentle massage is very good for the skin and muscles there, just like everywhere else on your body)
In case you're wondering why I even bother saying all this... it's because my GF turned 50 a couple of months ago, and she's the same bra size (32A) that she's been since she was 13. It doesn't make her any less attractive and desirable, and having bigger ones wouldn't make her any more so.
