Calling a raise preflop with QQ is fine, especially at a loose table.The guy with AA should have not continued to reraise you to minimize his own loss. He should have recognized that you may have a pocket pair that hit, especially when the queen came on the flop. I think you did the right thing by not reraising until the end. Not knowing if he had AK or some other smaller pocket pair - just calling was okay since you kept him in the pot for another round.I think good play on your part.
