FOUND! Specific spanked Castiel fanfic

[jackvalentyne.livejournal.com]

Hello! I am looking for a specific fic and I cannot find it anywhere. Castiel (gracelss, I believe) keeps messing up on hunts or puting himself in danger, so Dean decides to spank him. Cas think he can delay the spanking like Dean used to do (as he saw in his memories)- he quickly finds that he can't. Sam I think voices concern at first, but Dean says something along the lines of "relax, I'm just going to spank him." I'm sorry in advance if I rambled a bit. Thank you in advance for any help!  Edit: story was found! Someone PMed me asking if it was Mayalaen's Tumblr askbox request fics (chapter 39) found here: http://archiveofourown.org/works/4244124/chapters/13404697
