it seems I'm the only one around here who like the story (of the incest story)

I saw the original on reddit front page (with it 12k upvote, or something). Read the TL;DR and the update, and didnt care much.

What I like, is how someone can craft a story that thousand of people will upvote. What talent do you need to make a story viral?

Now that I think about it, I remember the same story a few year back: A brother pretending he and his sister banged for years.

It was debunked by the users within few hours of it becoming viral. I remember because my most upvoted submission, was a mockup of the original in r/circlejerk : https://www.reddit.com/r/circlejerk/comments/mt85z/i_never_slept_with_my_sister_amaa/
