Seeking story title.

[SEX_VAMPYRE]

Hello I'm posting in this thread here because I'm looking for the title of a story that was printed either under the erotic horror or non-human or maybe even the Mind Control category of Literotica. It's an old story posted here many years ago. The most memorable scene in the story that I can recall is when this creature somehow separate a couple ( could be husband and wife) either with drugs or mind control.The wife wakes up in a bed and she's all groggy and disorienred until the creature seduces her and makes love to her and then kills her with his tentacles. I'm guessing the creature needs to feed off sex .There are many more killings but this was the one I remember most vividly. This story is posted in Liteortica. Thank you in advance.
