The technique described below is something new to me.
I got it from a magazine article from the Pussologist at passion.com
Let me know if this something you've ever heard of. I'm not sure there is a real substitute for an expert tongue playing my pussy like a fine instrument, but this does sound intriguing.
Not really sure you want to go down on her just yet?
Then get a pair of non-powdered latex (or non-latex) gloves, a soft artist's paintbrush, and some KY jelly.
Learn to massage each vaginal lip, one good idea is yoni massage, take a quick course here.
Lubricate the paint brush heavily with the KY, reapplying as needed. When applied it mimics a sensation similar to a tongue. It needs to be a high quality, soft brush to work well.
After massaging you may want to move onto fingering your woman, with the gloves on it's more intense.
