Smother Box Ruin - Ass Sniffing Ruined Orgasm

I'm conditioning my slave to get aroused from my scent of my ass.. This is how I am conditioning to make him cum.. Firmly strapped into my smother box- I sit on his face and begin to tease and edge him.. The only air he gets to breathe in, is directly from my perfect ass.. I think my training is paying off- as he can no longer hold back from my gloved hand teasing, and is frustratingly ruined.. Hehe
