Lots of teasing on and around the lips -- gentle. Then after staying gentle on the lips for a little bit, you can start to tease with the tongue. Just whatever you do, don't plunge into her mouth. It's all about teasing. Start just off the lips ... try to get her to want to move her lips into yours ... at each stage, build up the tension. That's really what it's all about for a girl -- gentle teasing and anticipation.
