I can't find where I had this saved, but I remember this fic very specifically. - Sam and Dean are kidnapped/captured and wake up in an underground bunker-like room with one bed, a toilet, sink, limited canned fruit rations and no way out.

Found in comments! Details contain spoilers / under the cut.

I think it might be The Promise --- on Fanfiction or on A03.
