Headscissor and Facesitting Farts

Description: 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..
