Yup, absolutely possible. It surprised the hell out of me when it happened too lol. I was with a well known sp who apparently takes her job VERY seriously. Sometimes nerves get the better of me and the little guy just doesn't cooperate. I usually laugh, claim "c'est la vie", put on my pants and leave. Turn's out this wonderful woman had other plans, she just smiled and asked me to lie back down. She then sat on my face (which is always fun lol), and proceeded to go to town on me like nobody's business. I get off on getting others off, so that might have helped a bit, but it was more her determination to finish me coupled with her experience on just how to do so. It wasn't easy, and I'm sure her arm was sore for a couple days afterwards, but it was MAGICAL lol. If you're wondering about technique, I would compare what she did to vigorously milking a cow I guess. Anyway, I'm positive it was more mental stimulation that did the trick. Through her determination, she convinced me it was going to happen, and it did lol.
