All right, not always, but you get the idea. There are times when you know you're humping too hard, and you wonder if you're going to fall apart, but pain be damned, it feels too fucking good to stop.
So maybe you have a slight limp or a sore spot the next day; it's a pain you can savor, one that brings back sweet memories. (Of course, please be safe. We love you all too much to lose you to a wanton pelvis.)
