Are you looking for a particular kind of humiliation (e.g. verbal? Forced exhibitionism?). I don't know if you've read these yet, but Emma no knickers is one of my favorite writers of this type of stories:

For milder humiliation (even with a tender note), I also like "A Cheerleader Summer":

Then there's Viddler, of course, if you're in a cruel and nasty mood

And finally some shameless self-promotion. I used to write stories with humiliation themes too:
