I want to test out what this slave can handle and start to smother him under my dirty white socks. My big feet cover his mouth and nose pretty well, but he still tries to cheat by breathing through the edge of his mouth! Obviously, I can't tolerate that - so I grab some duct tape and tape his mouth shut! Now that he can only breathe through his nose, it's easy to smother him under my feet - and I can start to really test out his limits!
