For the first several minutes, I am reading manga while lying atop my slave, his head buried in my tits, unable to breathe. He lets out muffled sounds of struggle. I weigh a lot more than the little doormat so he can't push me off or make any kind of escape. I just keep telling him to shut up and stop disturbing me from my reading. I let out a fart which makes me think I might need to change positions. If I'm having a gas attack coming on it will need to go into my slave's mouth so I don't have to smell it. I re-position with my butt on my slave's head so I can safely push out the farts into the fart receptacle's mouth. Some of them are wet and sputtering, but the slave's seal around my asshole catches all the waste juices. He whines and squirms, complaining that they're too messy and gross. I just slam my butt down harder and make him keep sniffing and eating them up. I don't have the time nor patience for disobedience. I tell him that I was considering letting him out of chastity, but not anymore because he didn't do a good job as my fart seat. I let out a big nasty fart right on his chastity clitty before walking away.
