You know I love chan, but I think my guilty pleasure would be more humiliation!fic. Where Harry's being humiliated in some way but likes it. And watersports, though it's rare to read it done really well and, of course, I would only like it in Snarry or Remus/Harry. And I like crossgen with consent issues and power issues. I like bondage and spanking and slapping and stuff as well, but I tend to think that's a little more common and less likely to get me called gross, so I don't feel as guilty over it.
