Be very careful the first time you try sucking on a woman's clit. Some women are very sensitive and will shriek in pain. For the most part, once you've warmed her up with a little licking on the clit, place your lips gently around the clit and give a soft suck. You'll get a reaction right away. If she likes it, do it again and again, sucking a little harder and longer each time. Mix in a little jamming for an awesome combination.
