Hmmmm, this guy.
Well, let me see. He is pure evil, he is far larger than me, he is falling apart, there are numerous hazards on his body like jutting steel, sharp scales, and molten something.
If I could remove the "falling apart, jutting steel, and molten something," I would not be too terribly concerned having sex with him under a magically binding contract say he could not kill, eat, maim, burn, disfigure, crush, or injure me in any way physically or mentally.
Yeah, I have weird tastes.
EDIT: Wait, this is the same thread as the one from several weeks ago and I replied to it a second time on the same page as my old post?!
