Purpose of the Ball Gag

I was in a very talkative mood the other night. I really could't remain quiet enought for my Master his dinner. I just had so many thoughts and questions and all thes aha moments that I couldn't resists to share with Master. Master kept reminded to hold my 'thoughts' to the end of the dinner. Well silly o' me kept insisting. So Master decided it was time for the ball gag. So he binds me, sticks me in my cage, and tightly secures me with my ball gag. He stands towering over me in my cage and says, " This will teach you to listen and be quiet. A woman is nothing more than empty vessel and you should know that by now".
