It's pot luck alright, but it's still annoying when she backs off at critical mass. You're hard, dick bobbing in the air two, three inches from heaven, and you get 'no! stop!'

It sucks, even if you're a gentleman about it and I always am.
Even when I felt completely justified cussing the lady out, I bit my tongue and walked off or sent her home. Still got a right to be pissed for sure.
