New Sex Slave BDSM!!!?

So I'm a college student and quite recently something weird happened to me. A girl in one of my classes told me she likes me but instead of asking me out like normal she wants to become my slave (she told me she is into BDSM, exhibitionism, and humiliation). I told her I'd give it a try (even though I've never done anything like it before) because she is a pretty nice girl and definitely hot. What are some things I could do with her (inside and out of bed) that she would like? As I said, I've never done this and so I am looking for someone with experience in BDSM to help with ideas. Also, we talked about her becoming my slave and I want to test her limits and willingness, what is a good way to do that?
