I sit in the armchair and prepared a huge pile of worn socks and nylons on the couch table - then I call for the slave and stuff his head into the stinky pile. I rest my feet on his back and watch him closely - every time he tries to lift his head to get away from the stink I use my crop to keep him smelling :-D In the end I sit down on his back, take off my nylon socks and make him smell them as well!
