I'm surprised it hasn't been said but I absolutely love getting her off orally. Start with some light teasing with my hand while I'm enjoying her boobs. Kiss & lick my way down initially focusing on the inner thigh. Finally a few light licks that get firmer and deeper. Inserting a finger rhythmically (observing boundaries of course) until she's pulling my hair and grinding on my chin. If it turns into 69, now that's nirvana!
