Get her to relax, get cosy, lots of kisses, take it slow.

Stroke your fingertops lightly around her breasts, alongs the inside of her tighs.. around the pussy .. ye, find the clit but dont rub right on it or too hard for starters, just very light through the surrounding skin. Kiss her neck and breasts gentle while doing it.

When her breathing/sounds are getting heavier, go a bit faster on the clit.
Wet your fingers inside of her and get her clit more moist. Try some different things, 1 finger, many fingers.. just back/forth right on the spot but also "wider" moves, sidewise and up and down. See what gets the right reaction from her and go with it. When she's getting really hot go faster.

That's how I would do it.
