Best I ever received was in the back of a crowded shuttle bus on the way back to the hotel from a fancy dinner. She was sitting on one side of me and an old guy was on the other side. It was so dark in the back of the bus I think everyone just thought she was resting her head. I couldn't believe how much it turned me on. It only took a couple minutes before I came in her mouth surrounded by unaware perfect strangers. I will never forget that.
