Boy most of the video's on cunnilingus aren't very good. A few tips though. Don't go straight for the clit. It is best if you make her so hot to have it touched that she will push your head to the right spot. Get some lub like astoglide( it tastes sweet and is ok to swallow) and lay your head on her thigh and explore her pussy with your fingers well lubed with astroglide. You can kiss or lick her thighs, but move in slowely to her labia. I have found that women love to have their labia sucked. But don't touch her clit. Go back and forth. Then run your tongue along the groove between her labia and her clit, minimizing the touch of her clit. Be creative, don't do the same thing twice. Don't move to soon or spend to much time doing one thing until you what she wants. A finger gently in her pussy is nice, but don't fuck her with your finger. Put in two if she wants, some don't. Rub gently toward her pubic bone and behind it, tap the area. Ask how she likes it. Pull the hood of her clit back and gently stroke the head of her clit with the tip of your tongue. You can get harder and harder as she responds. Most women like to have cum before they tolerate this. Keep your hands busy lightly caressing her all over, her breasts and nipples, buttocks esp. But all over is important. Be aware of what she responds to. Don't be boring, act like you enjoy doing it. Be creative and vary what you do.
