I have my slave tied to a chair. He doesn't know it, but I am going to tickle him. First I shove a ball gag in his mouth to keep him quiet, then start tickling him. Just as I expected he squirms and yells into the gag. I switch into a better gag for him. I tickle him more, but he keeps making to much noise. I try another gag. I tickle more, but still to much noise. Finally I use a head harness gag and wrap duct tape all around his head. Finally he is quiet. Now I know how to keep my slave quiet while I tickle him.
