[F4A] I want to humiliate my slave girl and need questions.

So we are a lesbian couple and I want to make her feel humiliated. So I ordered her to show random strangers pictures of her friends. But I want to make it more humiliating so I want the strangers to answer a few questions, like, who is the hottest girl and so on

Give me some ideas about the questions that she has to ask
Thanks in advance
