It’s the coat.
If William is going to blame anything, he’s going to blame the coat. December has been relatively mild up to now but with the sudden cold snap, Arthur has brought out a military greatcoat and started wearing it around the base. It’s distracting.
Childermass and Grant both have similar coats (although Childermass looks perpetually disreputable in whatever he wears and Grant has been wearing his for long enough that William is immune). The coat does things to Arthur’s shoulders and posture. It makes him look imposing. It makes him look powerful. It makes William fantasise about being pinned against a wall, under that coat, while Arthur has his way with him.
Title: It’s the coat
Characters: William De Lancey/Duke of Wellington, Colquhoun Grant /Duke of Wellington
Summary: Arthur Wellesley’s greatcoat brings back memories for Grant. Part of the author’s The Twelve Days of (JSAMN fanfic) Christmas.
Author’s Notes: Returning to the WW2 era AU because onstraysod liked the idea of Arthur in a big army coat, and it turned out that William liked the idea too. This fic occurs some time before Jonathan joined the Ungentlemanly Magicians and also touches on the incident that Grant referred to in Chapter Nine (when Jonathan had a moment of excess post-mission enthusiasm and Grant assured him that it happens to the best of them).
