I sit down on the slaves tummy and pin down his arms under my knees - then I take one of my stinky socks off and press it on the slaves nose - while my other palm keeps his mouth closed - I want him to breathe only through his nose to make sure he gets the full odor of my sock :-D Then I take off the 2nd sock as well and make him smell both socks. I mix in some breath play, preventing him from breathing completely - then releasing only his nose - with the stinky socks in place of course. He has no chance but to inhale deeply through the socks!
