I think this song is about two ex-lovers that continually go back to each other.

The two lovers have a history of each time they meet they make love. But this time when they meet again, they don’t want to let this happen because they are both very guarded and hurt during their on and off again relationship. When they talk about their moral ground, I feel that it is they are agreeing to not make love. However, when they are in each other embrace “everything comes tumbling down” and they can no long resist the urge to make love.
