Depends on the woman, some women come from different things. For instance, there's a WG I punted with when I was in Vegas who came from me sucking her tits and gently rubbing her labia. Was incredible. I rarely if ever, put my fingers in. You've got to build it up slow, breasts and vagina are obvious but never underestimate how sensitive the back, shoulders and the neck can be. Not nibbling, gentle kisses and do not trace your tongue over her skin, kind of stinks afterwards.
What I have found is that if you put both of your hands like half an inch away from her skin, you create quite the sensation and run them over her body, do not touch her body, run over the back, the bum, tits, neck, thighs, it has an amazing effect and no matter how difficult she is at getting aroused, her body will respond to this feeling. Again, do not touch, do the same over her breasts and when the nipples begin to harden, start to work your way down, go back to the thighs (now you can touch), gently spread the legs apart start from near the knee (inner thigh region and work your way to the labia, same for both sides).
Then you start with gentle kisses on the labia, think of it like you are kissing her lips, no tongue or fingers, or teeth, just your lips. no pulling or biting, just kisses. If you are doing it right, her clit wll become engorged and be visible, again, do not jump onto it but focus around it and the labia, the outer and inner lips. This time she should be soaking wet, then gently cover the clit with your mouth and this is the key thing here, forget about licking, you need to suck it. Yup, gently as well. Build it up slowly, she will soon begin to guide you and you increase the tempo and before you know it, she's bucking on your face.
All women are different so getting her hot and bothered may differ initially. In my experience, the happier she is the more enthusiastic she is to reciprocate.
I do however advise that if you perceive any fishy odours, stop immediately.
