How does one eat a girl out? With a fork and knife, and lets not forget the napkin.
In all serious though, foreplay is great. You’d hate to eat a dryness. Kiss her and make out with her for a bit. Pull on her lip with your teeth. When she’s moaning and enjoying herself. Slowly work your way down her body. Kiss her neck, leave a hickey if you want, kiss her collarbone, her breast. Explore her body with your tongue. Learn what every inch of her taste like. Work your way down her body and hover between her legs. Kiss her outer folds, and then her inner folds. Savour the way she tastes. Tease her and move back up her body leaving her wanting more. Kiss her and let her taste herself on your lips. Go back into between her legs and blow gently against her sensitive clit, flick it, lick, suck it, kiss it, tease the bundle of nerves til she is bucking off the bed wanting you to lick it over and over and over again, draw circles or the alphabet, do what you think is right and what’s going to make her moan and beg for more. Get her to the point she is holding your head between her legs and fucking your face, or grinding into your face. Have her craving friction and needing a release, just by the stroke of your tongue. Stop before she climaxes just to hear her whimper and then give her was she needs. Give her the release she desires.
