Ashtray Against His Will

Your head can not go back or forward. It is locked up in the holder of the box. You have difficulty breathing, because the steel presses against your neck. But your real job is to keep still, on all fours. Because your head is converted into an ash-stand holder. The ashtray must not fall down. While I sit on the cage, over your head, and smoke comfortably, you can look at my sexy boots and then languish. But be careful, one wrong move, and my ashes will pour over your head. Of course I make it a little harder for you and keep the burning cigarette under your nose. Will you hold it?
