When she's hot, wet and moaning - push one finger into her vagina SLOWLY as far as your second or third knuckle. If you know how to locate her g spot, find it and rub it with your fingertips in a steady, circular motion. Combine this with simulating intercourse by pulling your fingers in and out of her vagina. As you develop your technique over time, penetrate her with a finger or two, and massage her ****oris with the thumb of that same hand all at the same time. Make sure to keep your rhythm and coordination synchronized.
