I've locked the slave in the smotherbox and bound his hands - and then also tape his mouth shut to make sure he can only breathe through his nose. I take off my high heels and reveal my moist nylon feet. I'll now smother him under my feet - and when I let him breathe, he'll have no chance, but to smell my stinky nylons! No matter how hard he struggles - there's no escape - no escape from my powerful feet that smother him - and no escape from the smell either! He's clearly disgusted by the smell and panics when I smother him for longer periods ... just the way a slave deserves!
