All slave gets is an asshole in his nose

Description: Slave is going to be my human chair. and i’m going to sit on his face and rest my dirty asshole right on his nose.    i want him conditioned to only want to sniff my fragrant ass whenever he wants to breathe.    after i have him take long deep breaths i put my full weight on his face and smother him. his mouth and face wrapped in duct tape with only his nose to breathe through.. i decide when and what he gets to breathe in..    i expect him to be ready to sniff and clean my ass whenever i need, even after i use the bathroom.
