Alcuin cried out sharply in pure pleasure, pushing back against him, and maybe it was the shout that muffled the sound of quick, insistent knocking on the door of the chapel. Alcuin did hear it after a moment, but he really didn't care in the least - it could wait.

But then the door opened (apparently they hadn't locked it when Alcuin came in), and suddenly Kersen was standing there, an expression of fear and worry on his face immediately morphing into shock and then embarrassment in quick succession.

His gaze lingered on them for perhaps a little too long, the way Alcuin's neck was bared, his eyes on the vein that arched his throat.

Then he was quickly turning his back to them - "Oh fuck, oh my god I am so sorry."
