It seems fairly clear she is saying those things to get a reaction. But not from a position of power and somewhat clumsily done too. The high five is for banging a chick, if you were in love they wouldn’t high five. That’s where the slut bit comes in. It’s not the fucking it’s the context. You saying “then let’s keep it secret” can be heard as “well you are a slut and that’s all I’m in for so let’s keep it hush and you can be ashamed in private“.

As you are already sexing and she is trying to get you jealous, this can go anywhere you want it to. One thing that is missing from your post so far is what your interest is here. How to proceed depends entirely on where you want to end up.
