DADA classroom. (private and NC17 :D)
Sirius and Remus left the Great Hall at a swift walk. Running would have drawn too much attention to themselves.
They entered the DADA classroom and a quick wave of a wand lit a few candles.
Sirius cast a spell to lock the door and waved his arm around the room before advancing on his boyfriend. "Pick a desk love." he backed Remus against a desk at the front of the room and kissed him deeply. "Ours... or..." he indicated the one they were leaning against. "Snapes?" he laughed.
