I am 16, kind of a late bloomer (started my period at 15) and I wear bra size 32A. I just want to go a cup up, i don’t ask much! The females in both my mothers and fathers family have medium and large breasts, no small ones. My sister is 13 and is 30A, nearly catches me. Please please please, i’ve been patient for so long, I need a clue, something that will help with my development. Please.
