meetings gone bad, but good

I was wondering if any meetings ever really went bad, but in a good way.

Like a bull getting too rough, or disrespectful. However in a way that made the experience better or more intense.

Or if the couple/woman got too nasty for the bull. Or maybe even the craziest wildest time. Or anything different other than the norm. Just curious of some real experiences.

We always hear the "perfect fantasies", just wanted something different.
