Use of your second hand is very important. This is a full-body practice and the second hand at ﬁrst is used for grounding, then for G-Area and Anus massage.
First you slide your hand under her butt. You rest your thumb on her Introitus. Then feel with both hands; feel all of her with both hands; feel with your “whole brain” and “whole being.” Try to tap into her energy. (Use Touch for Rapture practice here.) It can be very electric when you are on her “spot.” (Listen to the Finding Her Spot bonus segment for more about “Her Spot.”)
With your thumb, you might start to feel her vaginal opening (Introitus) grabbing for more sensation, contracting around your thumb. Stay on her “resilient edge.”
