LF: Specific story teenage Sam bitten by sucubus

[sandycub.livejournal.com]

I read a fic (or the start of one) quite a while ago and cannot find the link for it. I am hoping that someone can point me to it!

Teenage Dean and Sam were hunting with John. They were hunting a sucubus or something similar. John started to recognize the signs that Sam had been infected. He knew what he had to do (have sex with Sam to save his life) and knew Dean would freak. He sent Dean out to get something (don't remember what) and by the time Dean came back John had barricaded himself in the bedroom with Sam. John and Sam had sex several times. John did not enjoy it, this isn't that type of fic. He just was trying to save Sam's life. Dean spent hours screaming and beating his fists on the wall, etc. trying to get into the room. In the morning John leaves and lets Dean take care of Sam in the aftermath of what happened. Not sure what happened after that but I would really like to finish it/read it again.

Anyone recognize it??? Thanks!!
