Just remembered about this story if you like Processy TF stories
http://www.asstr.org/~lostboy/OtherA.../Succubus.html . Note though very mature rated with sexual content. Also this guys links to quite a few of them...Most are way to sexual in nature and involve too few TFs for me though.

I guess you could also say that Claymore anime/manga has it quite often as well as the main characters are always in danger of becoming evil. I posted a link to all the manga in this thread:

I'm a big fan of this particular TF as well especially to Succubus. If you find any others let me know!
. And as to Silent Mobius I sent you a PM.
