I take off my boots in the beginning, because I want to smother the slave! I press my nylon feet firmly on his mouth and nose to make sure he can't breathe - let's see how long he can take it! I try out some positions, first sitting in the big armchair, then standing next to the slave's head to push down harder on his face and then I sit down on his body to make it even harder for his lungs to recover. I smother him with my hands over his mouth and nose as well in between and always make sure he doesn't get a single whiff of air!
