You don't have to wait that long. Just stay playful and when you "ask her out" frame it in a way that you're going for a drink and she can come, just never stop being playful about it. Use push pull and accidental kino. Your hand accidentally slips on her hand etc. See how she reacts and take it from there. But do in a push pull manner. As long as you stay playful, there's no fear of rejection. You can even tease her she's hitting on her student, just keep it playful.
Besides kino, get her comfort levels up around you. Share something intimate so she opens up to you. What's the age difference between you guys?
