I don't know much about gags, There are all sorts I know, but I wanted to know about different types. What would be the best way to make a gag? I know there's always duct tape and scarves, etc, but I'm not sure how effective they are, and how safe. I know you can't completely stop a sub making noise, I just want something that will make actual speech impossible and make screams muffled and restraigned, but something safe obviously.
What's your favourite gagging method? What have you tried?
All advice is valued.
