Yeah, I can agree with that. I think that Q would let Bond top but I don't think he'd actually submit to him in a D/s way.
And I don't think that Bond would go to him for that. It makes more sense this way, that he has a place to go to where he can feel save, where he can let go.

Hehe... I can hear Ian Flemming turn in his grave over us, discussing his character's sexual preferences... *snicker*
