Either way, I'm nowhere close to being able to write that story yet, but it continues to percolate in my mind. I've always been fascinated by the thought of control by something terrifying and alien, like a dragon (or maybe a giant spider). The MC would have to very, very deep to make the victim love it; and that turns me on no end - even before I start thinking about the mechanics of sex with a dragon. ;)
With that in mind, here are a few pictures to stoke your own fantasies. The one above, as well as the first and third below, are by Julie Bell. The middle sketch is by Arantza.
Now three pics by Boris Vallejo. I've shown you the first one before, but it's so hilarious that I can't resist sharing it again. Ol' Boris was having great fun with the phallic symbolism on this one. He must have been laughing the whole time he was painting it.
All three of these artists - and many more - can be found on D4rkw00d.net.
Oh, and if MC-by-dragon turns you on as much as it does me, let me remind you of my previous post on the subject.
