Hello! I am searching for a fic I read many years ago. I can't remember if it was Inu/Kag or Sess/Kag. I think she works for him, and they fall in love, but she has no idea that he isn't human. When they have sex for the first time in his office, his concealment falls and she is shocked to see his true features. Does this sound familiar to anyone? Please help me find this story. It might not be a completed story also. Thank you!!! Fayemegan
