A special prisoner hood

You´d ordered a special hood for Ventress, (It looks like this: https://skelebomb.deviantart.com/art/Corporate-Punishment-736682309?src=MC_deviation_stack )
The hood was mostly white with a black face covering. the forehead area had a barcode on it. The hood looked a bit small for Ventress´s head, but it was quiet elastic as she´d soon find out.

You ondo her gag and then tread the hood over her head. It has microholes at the nose to allow the wearer to breathe, while appearing to not have any air holes. Now, this hood has a special touch slider at the barcode. You place your finger on it, and slide to the right. You hear a short squeak from Ventress as the hidden cords throughout the hood tighten up. Now she can´t move her jaw, her lips are pressed shut, her eyes are pressed shut by the padded insides of the hood. She was faceless, blind and mute. She was in large part, completely helpless...
