You found it. Then she made a sound you have been waiting months for.
So you sped up.
That is the mistake that ends it. Every guy does it. Almost none of them get to watch what happens if they do not.

Lean, Don’t Push
Use your arm and your shoulder, not your fingers. Finger strength quits in about ninety seconds. Hers does not.
Press and Hold
Push in, stop, count to five. Nothing else. She will fill the silence with her hips.

The Heartbeat
Pulse with her breathing instead of your arm. When she breathes faster, you go with her — same beat, not your beat.
The Count
Sixty of the same thing. Boring to you. Not to her. The repetition is what builds it.

Same Thing Again
The second she reacts, change nothing. Not the speed, not the spot, not the pressure. This is the whole page in three words.
The Palm Squeeze
Free hand flat on her lower belly, press down. Now she is caught between your two hands and she can feel both.
Two Fingers, One Job
Both fingers work the same inch. No wandering, no exploring. You already found it.
The Slow Build
Start at half. Take five minutes to get to full. She will ask for more before you get there, and that is the point.
If it goes sharp or she tightens up wrong, back off to half and hold there. Nothing about this works through pain.
Pressure is only half of it. The other half is what angle it arrives at.
