I'd suspect an ulterior motive. After all, she's over 500 years old and should be over the phase of having to be sleep with someone after a nightmare, so she's pretty clearly exploiting her "little girl" appearance. But why? Is she trying to seduce me? Or is she trying to trick me and take something from me, perhaps even my blood? I don't know, but to answer your question: Yes, I would. I simply wouldn't be able to say no to her.
