I have my slave's mouth taped shut, and hands bound behind his back.. I'm wearing nothing but a fishnet bodysuit, with no panties..  I have him in a headlock with my legs, and give him no choice but to keep his nose right on my asshole and sniff my farts..  He can't go anywhere.. Fart after fart- he has no choice but to take my scent into his lungs.. I step it up a bit and sit directly on his face so I can press my asshole into his nose with all my weight..  After I'm done I make him deep clean my ass until it's spotless..
