I know I answered this before but I remembered something only said one time. I performed oral on my wife and I started to get up to lay down in bed when she said, "I did not tell you to stop." At the time it was hot, but she never had to say it again since I just wait for her to push my head away when she has had enough or wants to use her vibrator instead of my tongue. I just read something and remembered this. Now I give it no thought since I know to stay in place until told otherwise or pushed away.
