Oh yes, once again I managed to recognize your story. :) It was first because of all the Russia knowledge, and then the fact that instead of H and D making out wildly every night, we got RST only at the very end. And the last couple of lines were so very f-like. :D
While I've enjoyed your fics for a long time now, I feel that lately your writing has improved even more. Can't wait what's next. <3
