Found it!
The scene is the second of so far 5 ficlets by cmdruhura in the Right of Conquest series published in the Off The Top Of My Head collection published on Twisting the Hellmouth
Ficlet 1
Ficlet 2 with the scene I described though Draco is only mentioned
Ficlet 3
Ficlet 4
Ficlet 5
The fifth ficlet was just published and I reread the series to get back into the flow and the scene was in the second one.
