Absolutely I read that fic! It was gooood. I don't suppose you read my Summer Solstice...? http://harlequin.slashcity.net/?p=264
I only ask because that had jealous!Arthur and a threesome with Lancelot.
However, I will let the notion mull around in the back of my mind, and see if I can't do a stand-alone piece. Because hey it so works for me, too! :-D
