The phrase "masterbated him/her"

Although, given the entire "fanfiction" component of this site, I'm not surprised that some mary suing is going on. In fact, I'm quite sure it could be far worse.
But how the story is framed and the very nature of the piece, really make the difference, if its a two chapter PWP jaunt that's about one to two canon characters blow-sorry- breezing through some graphic material and half his/her conquests just happen to be highschool seniors with bodys like pornstar barbie, I don't really care. However, if we're dealing with some traumatic, attempet serious mass of phony literature revolving around some magical character that hapily defys the rules of whatever universe, I'm not even going to bother finishing it.

There was a beyblade fic on FF titles Hallowwen something that neatly fulfilled the later, and "Takato's sluts" was a good case of the former.
