"You do understand that things will be done entirely on my terms from this point onwards? As your mistress, I have complete control over tonight's activities. Whatever I say, goes! You will obey my every request, no matter how humiliating. And at the end of the night, I WILL DECIDE whether or not you deserve to fuck my tight pussy."
"From now on, you will call me by the name of 'Mistress Trish' or 'Ms Stratus'. Understood? Now get naked for me slave and get that cock hard for me."
