Well, er, it's not finished, and it's over 2000 words despite my prediction, but I think I've found a way to give you all of what you wanted in the poll: "Helios Hyperion", Giles/Buffy, unabashed romance, h/c, and more or less vanilla smut of the scorcho variety. Though not all in the same sequence.
Um, and I wrote some G/Xander as well. Um. Finishing: not my strong point today.
