Always start gentle with just a couple light touches of the tongue. Women are very sensitive at first. Take your time and increase pressure as you go. Concentrate on the clit after a lengthy warm-up. Mix up short tongue wiggles with long slow laps. the next thing you know, she will be moaning out of control and bucking out of control. You can add a finger on the inside too. You don't have to go deep. Rub gently back and forth on the upper wall. When it feels like little bumps on the inside, go for the clit and hang on tight.
