Human Fart Bench Stifled and Ignored

I'm sitting full weight on my slave's head while chatting with my best friend. I banter with her over boys and sex, telling her all about a really hot guy I fucked and want to introduce her to. She is interested in having a threesome! Meanwhile, my slave gets no air except for when I let out big wet and nasty farts right into his nostrils and mouth. He squirms and struggles, locked in chastity and denied while I go on about the size of my boyfriend's cock. Mid-way through the clip, I pull down my shorts and place my asshole directly on the slave's mouth. I continue talking without acknowledging the slave at all. Then I call up the guy I was talking about and sweet talk him into having the threesome with my friend. He makes me so horny flirting with me, I can't help but touch myself and play with my boobs a bit while thinking of all the hot sex we are going to have while my slave stays locked up. He starts squirming around a lot at the end out of panic and fear.
