The Terrifically Twisted World of "Twilight" Fanfic

Natasha Vargas-Cooper delves into the universe of Twlight fan-fiction [1], where Bella and Edward generally exchange more than longing looks. We get some heavy breathing, a desperate "fuck me, Edward," and if not bodice-ripping, definitely thong-ripping. Someone has a thing for twins, so Edward gets cloned. The question arises: How far can one stray from Stephanie Meyer's world and still keep fans excited? I thought this exchange was interesting:

I asked Becca if she thinks the older readers and writers of Twilighted are scandalized by it.

“No,” Becca said. “It’s the teenagers. They ruin it. Younger readers want you to stick the story. The moms and older set of Twilighted are more sexually adventurous.”
