These are good examples of verbal humiliation, but not of humiliating actions.
For example, showing your slave how fast you can make her whimper in want, when she says she's not in the mood. Or making her squirm and pant in want when you're in public. Or making her wear way less than she's happy with in public.
Of course, each sub probably has their own little triggers, too. My baby is really humiliated if I ever catch her touching herself, so it's quite um,...rewarding to restrain her up on the coffee table, and make her fondle herself.
Then you add the verbal cues, on top of these ...
Oh, it's good to be alive!
