Do you think that this is possible?

Ok. the only way for anyone to give you a estimate is if we know the size of your mother AND your father's mother taken they're sizes and average it out that is the closest estimate you can get to your final size. Not all girls have discomfort during growth, I know I didn't. both walmart and target sell push-up just gotta look for them and shirts with square or rounded neck lines will make your breast look the largest. you can get your breast measured at Victoria secret for free and they don't expect you to buy a bra afterward if you don't want too.... just remember that petite breast are incredibly attractive to most men.
