Facesitting Dom

My poor helpless chastity slave is bound beneath me while I'm brushing up on some Smash Bros! I'm sitting full weight while his mouth is taped shut as well, making it especially difficult to breathe. The slave is of course, unable to lick or experience any pleasure of his own. He is subject to my needs alone and has no choice but to comply.After a couple rounds, I adjust a bit and sit forward. His locked up tiny penis is right below my face as I'm playing the Switch but I completely ignore it. I belittle him for its insignificant and size while covering any access to air with my thick thighs. His nose is buried in pussy that he could never have. He is an object and I treat him just as such. Unfortunately, I have to repeatedly remind him of this and tell him to shut the fuck up because he is acting funny today and wiggling around a lot. Weird, I thought furniture wasn't supposed to move! Eventually, I sit on his face full weight again because the point does not seem to be getting across.I let out one strained fart right on the slave's nose. He coughs and squirms in protest because it is extremely smelly. But I'm sure his skin soaked up all of my toxins and made for a perfectly reasonable fart cushion for me, so I'm not concerned at all. After some time, I turn around and cut off his air in a reverse position, making him struggle and panic more than ever before. I'm pretty sure he passed at one point near the end, but oh well. I still have a lot more practicing I want to do so if he is going to go losing consciousness then so be it. I sit on him more and go about my day.
