It varies from girl to girl as your metabolism is different than someone else's. Right now though, on average, your breasts should begin to develop around this age. It could possibly be within a few months or maybe a year. It is normal for breasts to develop as early as the age of 9 and as late as the age of 14. IF not developed by 14, the girl should see a doctor.

Are you sure about this because a 13 year olds breasts would look like a womans breasts
no
nothing that pretty big for a 12 year old nice
All I can say is I'm a 13 year old girl and I have plate-like discs in my breasts too, so hopefully that's normal.
Yes
Absolutely not! Them are perfect.
There is no age-chart for breast size.
Not if shes a milf! and has nice breasts
no.
There are some females fully grown with same size or even bigger.
Probably not because the guy is so young that he may not see pleasure in it and because the girl is so young her boobs haven't begun to develope.
