I disagree. It's evident that she's excited by the game they're playing. Coming out and saying let's hang out like normal probably would diminish the illusion in her mind. It possibly could work, but based off of the OP that doesn't sound like what she wants.
My guess is during the time she 'disappear's she's busy slobbering on some guy's rod that played the game correctly. After the excitment of that is gone she comes back to good ole reliable which is Charmer. Sometimes giving a woman what she wants is a good thing so long as it advances your goal. If she's looking for the mystery and excitment then give it to her if it means you'll be getting laid.
