I've ordered the slave to lie down on the couch and sit down on his stomach - to shove my stinky dirty socks into his face! I love how he's disgusted by the smell of them - knowing he can only take this humiliation because he's so submissive to me. Later I also stand up and press down my foot on his nose - and of course I take off the socks to cover his nose with them. For the finale I put them back on, order the slave to turn around and press his face into my disgusting socks with my ass on the back of his head!
