Get "American Pie: Band Camp" DVD and in the special features this lady teaches you how to eat out using fruit.

I've never done it though, so I'm not gonna give tips. But like PdoubleOTY said, whenever she seems to like it, do whatever you did again that 'caused her to arch her back or moan or whatever.

I think the video said stuff like licking around it at first, kinda goin' slow, breath on it a bit. Girls tend to get in the mood a bit slower than guys do, so goin' straight to business and trying to get her to orgasm too soon might not work well.
