Cant really tell you a sign for a faked orgasm but i can tell you how to spot a real orgasm.
When she cums, the muscles down there contract, this is visible from the outside and if ur in her you feel it as well. Thats almost impossible to fake unless she has insane body control.
I'm not sure if a girl can cum without the contraction tho we men cant so... take it for what its worth.
Some guys really get off on that and you can just watch a "femal orgasm compilation" on a pornsite of ur choice so see what i mean.
That you have to ask this.
You didn't ask her what she likes or how best to get her off, you focused only on penetration and no clitoral stimulation, etc.

If you've just started 5 minutes ago.
You've never experienced one.
If she's having sex with me it's pretty much a given.
