Of all the physiological responses to stimuli we humans have, the shudder has gotta be one of the most fascinating. Whether out of fright, disgust, or having a massive, hard dick pounding inside you, making you feel things you've never felt before, it's pretty cool. It's pretty impossible to genuinely shudder on command -- that shit be real. We think when in the throes of a solid boning, it's almost a way for your muscles to lift a white flag and be all, "We can't see straight anymore". How wonderful it is to get to that point! Ah, we're done for. Total satisfaction abides.
