Gassy Smothering with Playful, Bound Farts

Well since this guy begged me to sit on his face, i figured i would at least entertain myself in the meantime. he honestly had no idea what he was signing up for. i purposely bound him so tight, he had zero mobility so i could sit comfortably on his face for as long as i wanted. watch while i grind myself into his face, completely smothering him, while occasionally releasing a fart whenever the need strikes. he's so bound and helpless, all he can do is sniff them up and be grateful for any air at all! heads up: there is music playing in the background! all farts are audible (some are visible ;) but this is a real session so i've always got music playing in the background!
