Mistress Brianna has a special rubber hood on her slave's head making it so he must control his breathing at all times. If he squirms too much it will be a lot harder to gasp for air as she slowly edges and strokes his cock. Mistress Brianna guides him into a state of pure relaxation so he can learn how to control his body, mind and especially orgasms. He is not allowed to cum until given permission and Mistress Brianna wants to make sure his cock first suffers from a case of intense sexual frustration.
