"Speed up your strokes until you're right on the edge of orgasm then!" she says.

You do, and it doesn't take much. You tell her that you are on the edge.

"Now keep going that fast, and use your other hand to play with your balls and to press your perineum!"

You ask what that is.

"It's the area right between your balls and your asshole; push up on it a bit as you stroke!"

You do and you find it only increases your desperate need and frustration.
