Re-reading Sex God Method and thinking about how vibrators fit in with that will help with how to use a vibrator "best". Daniel Rose never mentions/recommends vibrators, they make it too easy to slip out of Immersion and Emotion and turn into the Bedroom Technician. You have to think about, how do I use this vibrator to extend psychological dominance?

Revising some basics first...

1. condom goes over the vibrator. You can't disinfect a vibrator well enough to use it on two people unless you wrap it. Use those free condoms that sexual health places give out, not the expensive ones you buy for your dick
2. vibrator goes on the clit. Maybe on the mound. Not in the vagina, up the butt, anywhere near her mouth
3. lube up the business end of your condom-wrapped vibrator. Moist is good, same way tongue beats fingers. Lets you/her slide it around to find the good spots.

Then the golden frame... all the pleasure she feels comes from you. Whether it's through your dick, your tongue, your voice, her fingers, the vibrator, it's from you.

Probably the single best position is fucking her, her on her back at the edge of the bed, you standing on the floor. Give her the vibrator and tell her to pleasure herself for you while you fuck her. This links pleasure and orgasm to your cock, means you can maintain eye contact, easy to talk to her, keeps your hands free to touch her/hold her legs open/whatever. "Show me how good I make you feel". "I want you to come all over my cock". "Let me hear how good this feels". "Show me how much you love pleasure". "Let go and come for me". If you feel moved and you can stay immersed, watch what she does with the vibrator, take it, and do that to her. But you don't have to be holding the vibrator to be giving her pleasure with it, if you have the dominance frame.

Other things, easier... give her the vibrator and tell her to show you how she likes to be pleasured. Have her lie back and tell her you're going to find all her pleasure spots, she's going to be a good girl and feel incredible pleasure for you, ...
