I have these urges all the time, and I, too, never cum quite as good as when I'm in public being watched by a stranger. I don't know why. But it's more than fun! A hot looking guy, doesn't matter how old as long as he's hot, in my eyes, and can get a GOOD look at me. If it's at night I sometimes turn on the interior light which, in my car, happens to be factory-focused right into my lap. If street lights are providing enough light I don't bother. But I can edge for hours like this and when I finally think I want to cum, I let myself. And it's REALLY mind-shattering. My whole body wracks with the orgasm. I have to be pretty careful about the driving situation I'm in. I haven't lost control of the car and of course don't plan to, but if you're not aware of your surroundings things could get messy in more ways than one! But what a huge rush. It's what drives me--I cannot get enough.
