I posted a question to providers and accidentally had it in private. so here is what I posted.
I used to see a Korean girl who moved back, she would put some hot water in her mouth, as hot as she could stand it then give me a bj. It was a big turn on. I guess she knew just how much to put in there because none of it ever spilled out even when I came in her mouth once. She also did it once with hot tea. If any girl would add that to her menu I am sure the reviews would be positive.
