A simple 2,5" ballgag

You settle for something thats simple, but big enough to really shut her up.
You pick out your biggest ballgag, the 2,5" ball is a bit soft but it needs to be or almost no-one would even get it past their front teeth. The ball had a simple, thick leather strap that was buckled at the back of the recipients head.

You dangle this infront of her face and you hear a bit of suprise.
"Oh my, I don´t know if I can fit that in my mouth Master."

You give her a meaning look.
"But I´ll do my best Master."
"Ofcourse you will. Now open wide Slut."

She gapes and you push the ball in. Had the ball been just a Little git smaller it would have gone in without a problem. But now you have to squeeze and push it in all the way. She probably couldn´t get it out on her own anyway, but you still buckle the strap behind her head tightly before you´re satisfied.

Your Slut tries to say something but can barely move her jaw and certianly form any cohesive words. It´s perfect for her, now she´s all yours...
