Obedient

You did well finding this one. She's a natural. You won't even have to train her, really. Just show her what you like. A good little subbie like her will do anything to please you. Because being used is what turns her on. If you want to make her happy, debase her further. Make her do the most humiliating things. Tell her what a disgusting pig she is while she does them. That might even make her cum.
