Now it's time to make him suck your cock. (read all of this page before you start)
Your man is most likely not gay. As such, he probably would be very uncomfortable giving the dildo a nice little blowjob. That would be way worse and embarrassing.
So you're gonna be rough. Stand in front of him holding your dong a few inches from his face. Pull the blindfold off of him, give him just a moment to take stock of the situation, then 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, make him gag. I promise you that is much better for him than if he had to give feminine head to it.
If you don't believe me, ask him. Say, "would you rather me not touch your head and just let you do it?" I guarantee you the answer will be "no".
Start really thrusting that dildo into his dirty mouth. BE RELENTLESS: force it all the way down his throat, hold it there periodically, make him gag. There should be a lot of drool, this is supposed to be sloppy. Pull that sopping wet dong out of his mouth and slap him across the face with it once in a while.
Once you've had enough, then you can continue.
