For Switch couples - Show your man who's boss.
If you have a strapon now its time to make him suck your 'cock'. (read all of this page before you start)
If you don't and your man chose not to insert the buttplug, then follow the instructions below but simply ram the plug into his mouth as best you can by hand.
Your man is most likely not gay. As such, he probably doesn't want to give the dildo a nice little blow job. That would be way worse and embarrassing. Instruct him to open his mouth wide and hold his head firmly in place by the hair.
So your gonna be rough. Have him sit on the floor kneeling on his knees and cuff his hands behind his back, while you stand in front of him holding your dong. (you may want to put a towel or sheet under you). Command him to start sucking. THIS IS IMPORTANT, let him get one or two quick sucks in on his own to get a feel. THEN GRAB HIS HEAD AND START FORCING IT DOWN HIS THROAT!
Literally force him to deepthroat the entire thing, you should make him gag and hold it at the back of his throat for a count of 5, still holding his hair tightly. I promise you that is much better for him than if he had to give feminine head to it, and as harsh as it seems, he'll be very turned on by it, as well as being able to use the safe word at any time.
If you don't believe me ask. Say "would you rather me not touch your head and just let you do it" I guarantee you the answer will be "no"
After you've held it down his throat for a count of 5 (slowly) tell him to pick a number between 5 and 10. This is the amount of times you should force him to gag for a count of 5 in between shallower thrusts. Remember keep FORCING him to deepthroat and gag and BE RELENTLESS! We want his eyes watering. Don't make him suck a cock of his own free will.
When his time is up you may continue.
