Matriarch Ezada Sinn training Her chattel to be a better ashtray

Description: I like it when my chattel dresses nicely, thinking if he looks pretty for me i will use him in sensual ways. i will use him in sensual ways today but in my ways. in all the time he has served me, there is one thing he has always struggled with. i like to use my chattels as human ashtrays, but he gags every time i try to use his mouth. well, today i am going to give him one more chance to be a good human ashtray for me. i want to see him open that pretty mouth and hold the ash in his mouth until i order him to swallow, without gagging. how well do you think he will do?
