Ha! Hardly. She's easily old enough to be my mother, and with that much of an age gap I'm fairly confident that, if anything, the FBI would most likely be knocking at her door instead.
Besides, it's not like every mature woman has a pair of massive gazoongas by nature either, and her's are actually above average.
For the game itself, her breasts size are perfectly acceptable in my opinion but even then, if need be, DC would be more than fine in taking some artistic liberties with her proportions in game if he so wished.
