Yes

There is now way, absolutely NO WAY that you are wet. So you confidently say:

"I accept the deal."

He looks at you with raised eyebrows and then say:

"You know I could trick you. I could for example use the vibrator and AFTER that check if you are wet. What do you think about that?"

That would be...an asshole move. So it would totally suit his character. You must look really terrified, because he laughs and says:

"Shame that you can't see your face. Don't worry, I will be fair. Or maybe...you should worry?"

And then he walks to you and directs his hand towards your pussy. But you are not wet, right?
