Seducing NARCISSIST LTR

The more I read up on it, the more I see LTR (and most women, actually) exhibiting at least moderate narcissistic behaviors.

I understand they need their narcissistic supply, but also need to avoid being a supplicating beta providing her validation.

Any tips on exploiting here self-aggrandizing and egotistical character to make her panties extra moist?

Help and wisdom appreciated here.
