If you truly love what you're doing, it will show in your actions. Other than that, just pay attention to how she reacts to what you are doing. Each little movement, each change of position. Remember the ones that she responds to favorably and repeat them. Ask her in a sexy way "Hmmm, that feel good?" and don't forget to let her know how much you are enjoying yourself. Let her know that you love how good she tastes, or how sweet she smells.

Though I am different from you,
We were born involved in one another.

For it was not into my ear you whispered, but into my heart. It was not my lips you kissed, but my soul.

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
