For the guys: Think about the tension with the arm of the lady for this step. Another important point is how to give some energy to have the lady in front of you again: The first two steps the lady goes to the front but the third step the lady has to come back to her right foot. You will let your left hand slide till you have her hand.
For the ladies: Don’t go alone to the front, you have to stay back. In this way, the guy can lead you. You go around of the guy with your upper body to him. The right arm have a connection with the back of the guy and it means, you have to press against his back.
