I wouldn't count you're aces because if that hits you're liable to be outkicked.
I doubt that we're looking at a villain with an overpair because most at 2nl aren't going to slowplay two streets like that before they make a stab at it. I'd thow out a bet of about $0.14 to $0.18 and see how they react. I think that sizing will be enticing enough that a weaker FD or some random holding may come along for the ride yet be small enough to get away from if we miss the river and are facing some real aggression.
