You may be a legal adult, but you signed the contract that gave me power over you while you stay in my house. And I’m about to use that power in a way that you may not enjoy. Because your mouth keeps getting you into trouble, with your entitled attitude, your complaining and interrupting. It’s time I trained you to have a little humility, and to be capable of silence. Luckily for me, I know how to do that, being a professional dominatrix, and I have all the equipment to hand. I only need one item for now though; a large cock gag, designed to slide right down the throat of the wearer, silencing them completely and delivering a humiliating message about who’s in charge here. I think a 30 minute spell of wearing this deep throat gag each day should make my point admirably clearly, don’t you think? I don’t care what you think, that is what’s going to happen. I’m looking forward to seeing an adjustment in your attitude - so open your mouth.
