Total Obedience
"Your mistress told me that, by the end of the day, when i send you back, i should write her a recommendation on how to proceed with you. So it would be in your best interest to show me your best today. Otherwise, well, you don't want to find out, let's put it that way. You need to accept that i make the rules from now on and when you break them there'll be consequences!. Anyway, my rules here are pretty straight forward, so listen up slave!"
1 - Do as you're told!. Easy, right?
2 - Of course no fluids will exit your body without my explicit allowence!
3 - I demand total obedience without any hesitation or questioning at all times!
4 - Always adress me with "mistress" or mistress Stella!
"With fluids i mean all of them, your sperm, your pre cum, your little dripples..even your tears slave!.
(You nod your head while still stroking at a steady pace)
"Oh, and of course you'll be silent unless called upon slave,..that should be self explanatory. Alright, keep going, show your mistress a little more about how powerful your cock is.."
