Make her humiliate herself. You don't have to say a word.

For example, does she like anal? Make her bend over a table or counter, hold herself open for you, and ask you to "please rape my ass"

Make her display herself, open wide, beg to be used, and refuse until she admits she's your cum slut.

Again, she is using the words she needs to hear, and seeing the merest smile on your face, and you don't have to say a thing.
