I sit down on the slave's stomach and pin down his arms under my knees - then I take one of my stinky socks off and press it on the slave's nose - while my other hand 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 second 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!
