For Switch couples - Show your man who's boss.
Time for a little pleasure.
Plant your pussy on your mans face and tell him to start licking. Make him pleasure you until you are right on edge but then stop and lift up.
If he did a good job then praise him. If not slap his balls twice on each side.
Get a vibrator and run it from his balls to the tip of the underside of the head of his cock to start building a large load. Do this for a couple of minutes whilst hovering above his face before sitting on his face with most if not all of your weight. Grind and smother him alternately with your pussy and ass until his cock starts to ooze pre cum from the vibrator.
When his cock is dripping pre-cum, lift up slightly, and pull your cheeks apart, instructing him to put his tongue in your ass. Do this for as long as you like, forcing his face into your arse. Explain that when you lift off he should immediately thank you for allowing him to worship you. You may, of course, try to distract him by slapping his cock around lightly whilst bobbing up and down on his face for a while.
If he forgets, slap his cock HARD.
