Fantastic Four Porn Comic???

Okay, so remember last week when I linked to the outrage surrounding that Pirates of the Caribbean porno comic? Well for professional research, obviously, I checked out the site and found that Sinful Comics also put out a Fantastic Four porno comic. It's a sometimes invisible Jessica Alba in a dirty romp with other characters, including Mr. Fantastic himself. (and no, the preview doesn't show if that stretches too). Last I read re: Pirates was that Disney was planning to file suit. Does Marvel know about this version and are they also considering litigation? Curious.
