Women's pleasure arises as much from anticipation, as from the actual event. With this in mind, try kissing her very gently on her tummy, and the fronts of her thighs, and then move very slowly to the insider of her thighs, but take your time. You'll learn from her reaction when you are doing something she likes, she may shift position, or even guide you with her hands to the part she wants you to kiss and lick. Take your time, and be guided by the lady, and you'll be a hero, but remember, it's not a race!
