Wow! This was just gorgeous and funny and hot and brilliant all at once, Mystery Artist (okay, perhaps you're not such a mystery, but... XD)
Absolutely loved all the art (and hooray for 69ing -- for some reason, you rarely see it anywhere in fic/art!) and the unfolding text-story and all the little asides. Your Ginny is adorable, your Marcus is hot (and apparently he has a magic cock! *g*), and everything is so wonderfully done. You have a very very lucky recipient indeed!
