A mouth mount dildo is a great way for a dominatrix to humiliate a slave while also receiving some physical pleasure herself. After all, she has no reason to let her loser of a slave stick his worthless cock inside of her pussy, but she still craves penetration. Facesitting can be fun, but tongues just are not long enough. So she straps a dildo around the guy’s face, making it jut out from his mouth as if it were a thick, cock-shaped tongue.
