Mistress Nyx wanted to teach her slave how to retain breath and she did it with her smoking fetish. The mistress made him wear a smoke mask and then she blew smoke into it and she let him hold his breath as long as he could before he started choking. She only let him breathe when he struggled too much. It was a lot of fun but he learned how to retain breath longer.
Mistress Nyx loves to enjoy her cigarette and that is what she was out to do today. But besides just enjoying her cigarette, she had to punish this guy who was a pain in the ass for her. The mistress smoked and when she was done, she took out another cigarette which she used to torture the guy. He was her human ashtray and she did not care what he felt.
