Sam/Dean or J2 psychological torture

[annastillstar.livejournal.com]

I'm looking for a specific fic I saw over a year ago on one of the knotting comms I think, but obviously now it escapes me. As, regretfully, does the title. This one was I think RPF, but may have been SPN AU. Dean/Jensen is a psychologist or something and has a bet with another person that he can convince a younger Sam/Jared that he's naturally supposed to have sex with dogs. Good times. Anyways, I think he spends a lot of time drugging Sam/Jared while he's sleeping and, of course, in the end succeeds with his nefarious scheme. Sound familiar to anyone?
