You Will Do As You Are Told!
YOU made the mess, so YOU can just clean it up! I cannot be held responsible for your little mishaps. Now, get out your cock and do as you are told as I instruct you in the correct way to masturbate. I'll use just a little lube to help you on your way, but once I have finished with you, you WILL clean up the mess you have made. Do I make myself clear!
