You obviously don't have breast. You have any idea how sensitive those can be? 

Don't answer that.

Anyway, in terms of actual damage would depend allot on cup size and if the person is using their bare hands/knuckles (along with where on the breast they struck.) 

Edit: also, groin shots to females, depending on where/how they hit...can hurt allot too... not as much as a male probably but food for thought.
