For me its all about getting the hand and the mouth working together. Think of it as jacking me off with your hand and your mouth moving together...also a little attention paid to the balls is great too. If you are on your knees, eye contact is a must. If I am laying on a bed and the girl is on all fours or whatever turn around and straddle my face. I love having a woman sitting on my face! ~
I like it wet and a bit sloppy. Seeing spit running down my wife's chin makes it seem so dirty, it really gets me going. Besides getting that dick nice and wet, I suggest licking it all over, running your lips over the shaft and head, and occasionally using your hand(s) when your mouth/jaw need a break. Dirty talk, mmmfff noises, eye contact, and taking a load in your mouth/face are all just icing on the cake imho.
