There really is not an average per age, as everyone's body is different. That is a lot like asking what an average pants size should be. If you are concerned about your current physical appearance, it is best to learn how to find your own measurements, and make sure your clothes fit the way that you want them to. Once you find the correct bra size, you can buy Bras that make your breasts appear bigger, smaller, or even fuller if there is something that bothers you. Just be sure that you are doing it for you, not for anyone else. You are good enough all on your own.
Due to different body types, puberty rates, genetics, and hormonal differences, there is no true average. Just like 30 year old women, there will be girls that have very small breasts, and girls that have very large breasts. There will be plenty of women that are somewhere in between.
The most important thing is to find the bra size that is right for you and your body type.
Stores like Victoria's Secret might be intimidating, especially when you are first starting out, but they can be very helpful. Remember that dealing with undergarments is what they do for a living. They aren't going to judge you for wanting to know what size you need, and they will teach you how to measure yourself for a proper fit. It's a free service that they offer. All you have to do is ask. It's good knowledge, especially since you will probably be buying undergarments for the rest of your life.
If you really aren't comfortable asking someone in person, there are also websites that have some good information.
