This mistress was pissed at the way in which this guy behaved. She was concerned that he was not changing despite her best efforts to have him change. So she felt that the best thing to do to him was to trample and humiliate him which she did using her puke. She gagged herself and she vomited into a bowl which she asked him to drink her puke from. He did.
When it comes to humiliation, no one does it better than this Asian mistress. She knows how to be cruel and to torture and to humiliate. She can do all at the same time. What makes her lethal is the fact that she likes to experiment with new ways of punishment. For this loser, she chose to go with puke fetish. She had him drink her puke and enjoyed as he did.
