Our Head Harness is sadly one of our least appreciated items. Sure it takes a few minuets to get on. But when it is on, your slave CANNOT move their jaw! This makes it a perfect gag replacement for long term wear. Try inserting a thin tube into the slaves mouth as you lock this on him. Then advise him he will only be consuming water and protein shakes for the next 24 hours! His eyes will show his despair, but thanks to our Head Harness, you won't have to hear any of his complaints!
