Subby and I play a fun game on the floor where I shove a buttplug in his ass and make him hold it in there while I wind up and kick him in the nuts, over and over again. But once he lets it slip out, I take the plug and shove it in his mouth instead, replacing it with an even bigger one up his ass. I continue to kick him in the nuts and every time he lets a plug slip out of either his ass or mouth, I switch it for the other, and making sure both holes are plugged again, proceed to kick him fiercely while showing no mercy.
