My slave has been restrained in a cage in a way that leaves his head exposed through a hole so that I can use his mouth as my toy and ashtray. I attach clamps to his tongue and lips to ensure his mouth remains wide enough to collect my ash, smoke and spit. I pull them off harshly for my amusement and re-attach them when his mouth gets too wet, leaving his lips covered in sores. However, all this is to be expected and tolerated if he wants to be my favourite ashtray that I can use with my friends at parties.
