Oral on her, well done.
One of the most reliable ways to bring a partner to orgasm. The technique is learnable. Structure matters more than fancy moves.
In surveys, women rate oral as one of the most reliably satisfying things their partners can do. Many partners overestimate how hard it is to do well.
The structure matters more than the moves. Spend time, find what works, do not switch what is working.

Why this works so well
The clitoral region responds well to oral stimulation. Tongues are warmer, softer, and more variable than fingers.
Most failed oral is not a tongue problem. It is a structure problem. The clitoral stimulation page covers the underlying targeting.
Four phases that work
Treat these as a sequence.
Phase 1: arrival
Slow, broad, exploratory. Outer labia, inner thighs, lower belly. 5 to 10 minutes here separates competent oral from average oral.
Phase 2: introduction
Indirect contact. Light pressure near the clitoris, not on it directly.
Phase 3: direct
Direct contact with the clitoris. Try patterns until you find what produces clear response. Then lock that in.
Phase 4: through
When orgasm clearly approaches, do not change anything. Same speed, same pressure, same pattern.
What we know from research
Surveys consistently rate oral as one of the most reliably orgasm-producing acts in partnered sex, second only to vibrator use.
Four rules that work
These cover most of what separates technique that works from technique that does not.
Spend time before direct contact
5 to 10 minutes of broad, indirect work first.
Lock the rhythm once it is working
When you find what produces clear response, do not vary it.
Do not stop early
If your partner is close, push through 5 more minutes.
Use your hands too
One or both hands on a thigh, hip, breast, or with one finger gently inside.
