Your instincts are important. They cause you to do things like thrash out of your binds as a defensive mechanism. Which is cute, but it needs to be prevented from actually accomplishing anything.
Imagine your instincts, the Primitive parts of yourself. They don't really know anything. They need to be told what to do by your brain. So tell them. Tell them to shut up and listen.
Perfectly stupid, they don't know what's good for you, and that's okay. I'll tell you what is good.
Tape the mouth of your instincts, blind your instincts, bind the body of your instincts, and Glue noseplugs in so they can't breathe. Your instincts don't need oxygen, so seal them up. Completely flatten their mouth like a wall is built over them.
You're my doll after all now, not a real person.
Look at the bulge in their mouth, isn't that much better than listening
Your mouth which starts out no big and fat needs a lot of bondage to please me. Here I have shut your mouth and plugged your ears and filled your mind with silence. If you are not like this yet you should approach this state.
Your instincts are stilled and molded and controlled into a brace for your muzzle, no longer saying anything, mutely reinforcing your silence through being reshaped. They were so annoying, so it is very satisfying to make them like this.
Hnnnnnnnn nnnnggggggghhhhh gggrrrrrnnnnnmmmmmm nnnmmmmm
Your mouth just needs to keep getting sealed, and Tighter and Tighter. Anything which contributes to your uncontrolled expression needs to be silenced. Your instincts do, and are muzzled, slowly thrashing as they are mummified into a useless state.
Imagine them as a green lizard, a helpless creature under my power, no longer speaking to you, only squirming as I want them to in their little, tape habitat.
Lost in your mind, their animalistic noise sealed with a wall of tape, no voice or air, twisting around to help you entertain me.
Be a good viewer and let silence fill the bottom of your brain. Memorize this lesson so it will gain stronger in effect over time and teach your brain the way it should be.
