Something to watch out for if you get (from the man's pov) too 'enthusiastic' is the ball coming off. If you use a 'robust' circular movement it can unscrew the ball. This has happened to me twice now. I can safely remove and store both the post and ball from a VCH orally!
If you put your tongue 'flat' against the piercing (this works with a straight bar bell), against the post and trap the ball between your tongue and the clit, you can move your tongue side to side and 'flick' the ball over the clit. This has a tendency to make your lady smile a bit. Also, try flicking the tip of your tongue under the bottom ball and let it fall against the clit. Again, another crowd pleaser.
Great minds think unalike, that's what makes them great. Sheep think alike, that's what makes them sheep!
I'm not wise, I've just made lots of mistakes!
