Who did this?

One of you wonderful people wrote some Sam/Rowena smut. It took place in S10 but I don't know if it was written during S10 or later. I do know it involved Sam having Rowena in chains in the Brewery of Doom. I forgot to bookmark it and it's killing me. It was written by someone I follow and hopefully someone who follows me as well. If anyone remembers this fic, please give a shout!

Found in the comments, thanks to the ever lovely frozen_delight!
