How to tease your man?

Okay so I need help trying to tease my man sexually. He always teases me, and yesterday we were teasing each other (most him teasing me). He told me that I don't do it as often as he does. I told him I don't really have anything original that I can think of because the things he does to me is also teasing for him, but it's the same thing and I don't want to bore him. Can you help me? Any tips or suggestions to "spice things up" when teasing him. We have talked to each other with what our turn one are and fantasies were, but there were few turn one he could think of, and most of them were fantasies.
