Miss Wildfire‘s sub has said he wants to quit smoking. To no longer be her ashtray. 
She is going to help him by using some mesmerising techniques.
Taking him under, he is suggestable to her words.
Of course. The ‘help’ on offer is that he no longer wishes to quit smoking and now craves her smoke and cigarettes.
When this is over – she puts it to the test. The trigger is complete and how now craves and yearns to be her ashtray.
She lights up… and puts him back to use.
Miss Wildfire is horrified. Someone has applied to be her house slave, but he doesn’t like feet!
Serving foot on command is not enough, he must love and appreciate them. But, he just… seems not interested.
He does generally seem fairly useful, but this won’t do.
So. The intelligent Mistress has an idea. She invites him to play a game. And, she produces a watch. And soon his eyes are following the watch and he is mesmerised under her spell. Using hypno to convince him otherwise.
The trigger is implanted and on awakening he cannot get enough of Miss Wildfire’s feet, simply devouring them. The results… are… staggering.
