One thing I don't do is to try and "force" her to take me deeper. I want her to be comfortable with what she's doing and not to feel compelled to do more. Usually my hands will be used to rub her shoulders or back or massage one or both breasts. I also like to very gently tease her by lightly touching her ears, tracing them very gently. I want the experience to be as wonderful, romantic and sensual as it can be for her.
