Words can be just a strong of a turn on as the actual oral sex, you don't want to limit the experince for your woman by not doing all that you can. Tell her how sweet her pussy looks, and that you've been fiending for it all damn day long. Women respond tremendously in situations like this, due to many years of bullshit (for the most part) from other men, they have a complex about their bodies. Some will tell you they feel uncomfortable with their bodies, others won't. If you tell her how much you love her and how sexy you think she looks it will work wonders. Even if they are basically ok with themself complimenting doesn't hurt. If you know for sure she's not comfortable hearing about her body then take it easy. Too much can make them even more self-conscience which will accomplish exactly the oppisite. You should know your female enough to know how far you should take it. Just try to make her feel as if nobody else exists but her. Done correctly, after some time has passed, you will have helped build up their self-confidence, What does this have to do with Eatin pussy? You ask, well the more at ease she is with her body and sexuality the more open she will be too letting herself be pleasured. If she is open minded, and maybe even freaky, tease the shit out of her, but not too much, just to where she is about to tell you to shut the hell up and eat her out! And make SURE whatever you tease her with is something that you can deliver, this is imporant :)
