My slave hates the smell of cigarettes and I use this distaste to humiliate him. I sit on the couch and rest my legs on his body when I light up my cigarette before i sit down on his body and blow a huge load of smoke right into his face. But that's pretty normal for him so I decide to take it a bit further. His hand is used as my ashtray and while I'm holding his nose closed with my hand he has to open his mouth and inhale the smoke i'm blowing out of my mouth. He has to keep the smoke in his lungs for a long time before i allow him to exhale it.
