Bilbo didn't smile. Or grin. This is work! This is a way to help a friend. "I've tried everything else but you'll have nothing of it," the hobbit grouches as fingers far more delicate than any dwarf's encircle and enclose the king's softened member. He'd expected perhaps a little life in it at the start to be honest. How long has it been since Thorin found any pleasure, even in himself?

Not discouraged, and not playing any coy or tentative games, Bilbo gets right to work and his hot little hand provides just the right amount of friction and tightness to it.

"You've been still in the wrong ways, besides. Perhaps you should spend more time through the secret door and gaze over the ledge awhile?" Yes. Bilbo can offer advice while he does this, happy to feel Thorin lengthen and harden finally at the touch of his fingers. "It's quiet out there and not many here know of its location."
