I am still working up to my wife being comfortable enough with me licking her to cum. She's only cum once this way, and that was from a woman's tougue. (She has serious anxiety over any oral contact, including kissing beyond a peck, due to abuse as a child.)

A couple of nights ago when she was on top, I asked her if I could slide down to taste her. I made my tougue flat and moved it only a little as she moved over me. She came closer to orgasm than ever before this way, and later remarked with a bit of surprise "That felt pretty good!" So I'm encouraged to continue, because I love it and I know she will too!

ps
Yes, I was jealous.
No, she couldn't describe what our hottie neighbour friend did down there.
Yes, she is very reliably orgasmic otherwise.
Yes, we should have our friend over more often!
