Erotic humiliation is a great tool for a Domme. You can berate your slave and degrade them in all kinds of kinky ways. Humiliate to train your slave. Or, humiliate them just for the fun of it. Some fun ways to indulge your need to objectify and humiliate a slave:

Lead the slave on a leash
Have the slave serve as a human garbage can
Make the slave hold a coin against the wall with his/her nose
Inspect the slave’s body cavities in public
Make the slave wear a mask or sensory deprivation hood
Keep a slave in a cage indoors
Make the slave eat without utensils
After sex make the slave lick off your cum
