Intense fart smell conditioning

I let loose blast after blast onto his vulnerable nose, covering his face and cutting off his air entirely in between farts. When I'm not farting, his nose is completely buried in my asshole and all plugged up. This clip is a very intense experience as each of my farts are extremely stinky. They make him cough and gag over and over. He struggles to move his head out of direct contact from my ass in desperate attempts for clean air, but it is all in vain. My ass is simply too huge and I completely overpower him as he is bound and cannot move me. The power I exert over him is extremely hot in this clip. Kitten has never felt so completely impotent. Normally he enjoys sniffing the occasional fart, but I may have pushed him over the edge with this one. At the end, I start making a bit of a mess as my farts become runny. I end the session here for the moment. I'll be back to continue his training when I have more gas.
