One way to instill dread is to plant doubt in a woman's mind by suggesting that she doesn't satisfy you as well sexually as other women.

It's important to suggest this subtly, through teasing and offhand comments, rather than criticizing her outright (which would nuke her ego from orbit).

Here's a recent example that occurred with a plate of mine:

Her: [some situational comment about her sensitive gag reflex]

Me: So that's why you give such lousy head [delivered with a playful smirk]

Her: I hope you're joking. You are joking, right?

I kept smiling and said nothing in response. Thread cut. Later that night we 69ed and she was particularly attentive.

It's by keeping a woman wondering whether she's good enough for you that you get her to work hard to please you.
