I’m a big fan of implied bondage. I find it to be a much more powerful head trip when your not moving because you’ve been told not to move. I find this to be true whether I am topping or bottoming. That theory applies here, the bottom is only gagged because the top has told them to keep the ball in their mouth. The bottom could be spit it out at any time, but instead they have chosen to drool all over themselves instead of not submitting.
