My little chastity slave is very excited for the chance to be my seat! However, his expectations are ruined as soon as I sit down and he catches a foul waft of my panties. I tell him I've been wearing them for a week straight. They are absolutely rotten! I've been sweating, leaving my asshole dirty and secreting juices from my holes nonstop. It's like that when I'm exercising and getting fucked daily! My slave gags on the musk of my boyfriend's cum. It's all built up and now my slave is getting his lungs filled with dangerous toxins with them smashed onto his face. I relentlessly bash his face up with my ass while subjecting him to humiliating farts and verbal degradation. He coughs and gags, begging me to let him go. I thought he wanted this?? I'm so confused! If he expected to be deserving of a clean facesitting session, that's his own fault. I believe my slave is lower than dirt so I treat him as such. I call him a short, ugly virgin and make him tell me that he loves disgusting farts. I make him put his mouth around my asshole and swallow them whole. I cut off his air periodically, laughing as I wonder how long he'll be able to go without. Toward the end, I decide that making him silent is the only suitable fate for such a pathetic loser. I tell him that he is too weak to resist, so he might as well give in, as I put him to bed deep within my ass crack, firmly planted full weight on his face. He squeals and struggles until he loses circulation in his head and stops moving. I can't stop laughing as he passes. When he has gone still, I get off and leave my rancid panties on his beat up face.
