You try to change the subject, and ask her why she brought you here. Wouldn't a normal beach be good enough?
"No, a normal beach won't be good enough, not for what I have in mind for you. Can you just indulge me a bit on this?"
Sure, you agree.
What you want to ask, but don't, is something that is even more confusing to you: Does she really want you to be teased by and lust after other women like Faye?
