Oh, I have LOVED the phallophilia prompt. It's had Draco with a tiny prick and Neville with an enormous one. It's brought the whole 'actually, it's not what you have but what you do with it' argument to the fore. (Sometimes *ahem* LESS to the fore than others...) And this? Is just very much both of them being ThemLike and still making a couple.
I adore Ron/Draco. And this is just brilliant :)
