While trawling this wonderful site and forum for info about my upcoming trip to HK (see previous thread "Operation Roger") I've become very interested in the so-called "fire/ice" BJ technique of some WGs there. I've never experienced this and am definitely looking forward to it when I visit.
In the meantime, I'm considering bringing up the subject with my extra-curricular girlfriend here in Japan. She's a "nice girl"

and needs to be gently introduced to anything of a sexual nature, but once informed she's extremely willing. I've just taught her the joys of mutual rimming, for example. And she took to facials like a duck to water

.
(Needless to say, I'm not going to do any of those things with the ball-and-chain

who only gets the basic treatment, and even that only when absolutely necessary.)
So I was just wondering if any other bros had picked up ideas from WGs and passed them on to their GFs? Any thoughts on this?
