When you Queen him make him lick your ass… this is extremely erotic and unbelievably pleasurable.
If you are on top of him slide over him so that he can only lick your ass, then sit on top of him for a while and force him to give your ass wonderful oral pleasure. If you are lying on your back with your legs open, you can swing your legs way up in the air to expose your ass to his tongue. one of the better positions is just to lay down on your front and read a book, watch TV, or just burry your head in a pillow while he licks your ass from behind. If he tries to move toward your pussy push his head firmly back to focus him on your ass and to show him who's in charge
The idea is to show him you are in command as well as get some really great pleasure and try something different. It's not necessarily humiliating, but it definitely show's you are in charge and you get what you want.
Tell him how much you enjoy it while he's doing it.
Do this anytime you want to assert your feminine authority and you are forcefully queening him.
