Like others have said, I can't tell you what every girllikes, only what I have found that pleases the ones I have been with. The key for me so far has been "combinations". I usually start out very softly with my tongue relaxed and flat. Up and down a few times, and then switch directions, working in side by side motions, with some circular motion worked in.
Then I'll make my tongue a little harder, tracing the lips and periodically brushing up against the clit. About this time, I'll start sucking on her gently in between strokes.
Depending on if she likes direct contact or not, I'll strat doing some fast little flicks with the end of my tongue.
All along, I'm listening to what sounds like is pleasing her the most, and even better if she'll verbally tell me.
My absolute favorite part is when she orgasms. I usually have a hard time not cumming myself because it turns me on so much.
Damn, now I'm horny :biggrin1:
