Yap Stuff. Stuffing a young bimbo's mouth with objects. An oral examination and investigation.
It's one of my favourite training methods as it very simply objectifies a cunt's mouth. At the same time it completely strips dignity and removes pride.
Take a good look at petgirl Em here. Compliant because she has lower intelligence. Her bouncing udders make her look even more dumber. I'm always amazed at how quickly a cunt becomes animalised when you spotlight her udders. Milk bags for feeding young just like a cow.
Of course her dumb face completes the picture. Pretty dumb.
