[Missed Miss]

It can't hurt for you to do massage, though. At this point, you should focus on growing properly. So, eat healthy, sleep enough, exercise regularly, don't stress too much.

I don't think growing properly will give results though. As I said my mom was an A before surgery. But which massages could help me?

It doesn't matter. My grandmother had huge tits and 3 of her daughters did, too, but my mom had fairly small ones (b-cups). You CAN'T really go by what runs in your family, especially at your young age. Give it another 6 to 8 years. ENJOY being a kid as long as you can! You'll have LOTS of time to worry about growing the twins after you hit your 20's! It only takes about 2 years, as far as I know.
