First start with a very small motion on her clitoris, either a circle or up and down. Make the stroke like you are stroking the head of a pin. Be aware of changes in her energy. Feel her going up, staying the say, or going down in her arousal and adjust for this.
Use even strokes to allow for her to surrender to the almost hypnotic, very predictable, reliable sensation you are delivering.
If you lose continuity it’s very disruptive for her.
