I really like the tea message, BUT I don't think you should've spit it all out in one shot. By just telling her "It goes in dry, it comes out wet. The longer you keep it in, the stronger it gets. You can have it in bed with me, on the couch, or the kitchen table..." then ALLOW her to guess. This creates Tension and when you finish it before she gets a chance to guess it removes any tension you built intially. Delivery, delivery, delivery. So don't be afraid to break up your texts and leave them open ended. Sometimes I'll just write "Huh" or "Wtf" and she has no idea what I'm talking about.
Now because of her response it could be many things. She was busy. She didn't feel the need for an elaborate response. Or she has lost interest. In any case you basically made yourself the dancing monkey in the instance because of her lack of response. So let that be the last time you write a clever text to her. Keep it simple from now on.
If you don't have definite plans set up then there isn't a reason to expect anything definite. If you didn't take the time to set a time and place then she really isn't flaking on something that doesn't really exist. Have more conviction in your decision to set up a meet. Perhaps you can let this one go and try again next week.
