I'm looking for a specific fic which I am pretty sure is bottom sub Sam, where Dean has him tied down to a table, maybe it was prostate milking I know at some point Sam begs Dean to ''Help him come.''

Then Dean says something like, ''You're already coming.''

I know at the end is fluffy aftercare, I would appreciate any help in finding it as it has started to annoy me that I can't find it, thanks.
