How can i tell if she came?

Randomjelly is right. Those vaginal convulsions aren't some that can be easily faked.

My personal aim is to send the woman into the throes of orgasm. The hot and heavy breathing, loss of awareness, twitching and shivering, and maybe even some stupid gibberish. Lol. I wanna make em pass out if I can.

Then I know shell never leave. Mwahahahahaha!

The muscles comment is correct. The walls of her vagina should spasm. Don't trust anything else...we are great fakers.

With some girls it's no more than a little shudder. With some it's like a small wave on a beach. With some it's a crash like a cymbal. With some it's like a tsunami.

You never know what you're going to get.

Mine are mostly in search of a vowel: "nnnnnnnnggggggggggggghhhhhhhhhhhhhtttttttttttttthhhhhhhrrrrrrgggggggggggg!!!!!!!!!!!!!!!!!!!!

Yeah, sure, it's pee.

Eyes and cheeks, but especially eyes. There's a faraway, drugged, detached look that takes about a minute to fade. You'll know it when you see it.

We don't lie!! U should feel her inside muscles contracting an she will b sensitive.

U will drown till the bed is filled with her cum that's how u know
Some of them small amount
Others shivers like a crazy vibrator
But u will definitely know she will be different
Never ask they will lie

Trust me, you will know.
