At the end of an intensive slave training session I now deprive my slave of oxygen. This is how I prepare him for his last task for today. After he has finally cleaned my boots, I want the intense smell to disappear from them as well. If I now allow my slave to breathe oxygen, it will only be with my sweaty, smelly socks over his nose. He has to remember this smell. This is the scent he will have to suck out of my boots afterwards. He has to sniff it out right away. Completely. But until then, I make sure that he will be thirsty for oxygen and press my hands over his mouth and nose for a while so that he can't breathe.
