I sit down on the slaves stomach 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 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 😀 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!
