Huge relentless farts on my slave's face

My slave's reward for being an exceptional toilet slave is to eat up a storm of my farts. In my gassiest clip yet, I have my little chastity boy pinned to the bed and his duty is to inhale and swallow fart after fart. At first he is not allowed to lick, but after my farts make my ass all dirty and messy, I require his tongue to clean it up. I tell him to open his mouth wide to take my farts. As I blast loud rips into his mouth, he tears up and gets his face buried into my ass. He can scream as he cleans the mess up. I make him lick me deeply and taste another fart. Then I get up and rub my ass on his from the reverse position. He sniffs more farts that make him cough and gag. He lives to smell up my stinky gas so I know he likes it no matter how much agony he is in. Turning back around, I bounce my ass roughly on his face and jerk up his nose and cheeks. The butt drops shake more putrid gas out onto his face. At this point, he is hopeless and can't even protest anymore.
