I love a good gag, preferably soft as my jaw locks easily. Believe it or not, there is a proper way to gag someone when using soft materials. The key is to use something soft and sanitary to place inside the mouth. This not only muffles the sound but also keeps the mouth slightly open in order to place the gag (in this case scarf) around the head, the gag also holds the material inside the mouth in place.
I look forward to more practice in a couple of weeks.. when I see pet!
