Are you looking for "The Internet Is For Porn?" It's over here.

Also it has come to my attention that some idiots are a) linking to this story without the proper warnings, b) reccing this story without bothering to read it all the way through, and c) blaming me when their friends start going EWWWW. You know who you fucking are. Let this be a lesson to you: don't rec it if you haven't fucking read it.
