Oh sweet summer child. Dwarves are hardly repressed, they're quite open about sex and all that, just... Thorin has kept himself away from others in that sense. Getting close to people just meant it hurting more when he lost them. Getting close to people meant a lot of things, but since Bilbo Baggins... well.

He can't help himself, especially when the halfling is touching him like this and sitting on his lap. Surely it must mean-- but then Bilbo is pulling back, looking quite shocked by what he'd done.

"I..." Oh. Oh so it wasn't like that. Thorin's hand lingers, just for a second more before it drops, resting on the arm of the chair once more.

"I merely--" Just brush it off. Clearly this was nothing but a misunderstanding. Work. That's all it was to Bilbo.

"Just got caught up in it all."
