Look at that lady's face. I'm sorry, nobody in the history of fisting -- whether fistee or fister -- has ever made that damn face. That's a beatific expression reserved for occasions like "a new delivery of wainscoting" or "a perfectly seasoned shepherd's pie" or "the third consecutive 67-degree day this week" -- not "becoming your own human hand puppet." This picture belongs on the album cover for Pure Moods for Fisting. (Also, what's up with the blue background? It's like a lazy day in the Fortress of Solitude.)

It may not surprise you to learn that the Wikipedia entry for Godzilla Bukkake just redirects to Crooked Little Vein.
Those aren't anywhere near the most terrifying. Sure the images are salacious, but they do a disservice to wikipedians' approach to sex. This has got to be my favorite sex edit ever, where "she straddles one of his legs" was expanded from five steps to six, as it remains to this day.
