My companion and I come across a helpless slave seated on a stool. The idea strikes me to force him into the stool, rendering him immobile while providing him with a close-up view and whiff of our feet, a tantalizing prospect that he cannot touch or smell as he desires. It will be a cruel torment for him to be so near to our feet yet unable to possess them. We will take turns in our game, using our heels to obstruct his hands.
