Bilbo found that he thoroughly enjoyed the kiss. It wasn't what he had expected from this evening, but it was definitely a nice turn of events. Especially since Thorin returned the kiss so willingly. And seemed pleased by it as well.
"Just the day?" he asked, arching an eyebrow at the Dwarf. "I think we can do better than that."
He offered Thorin a small smile as he spoke. "Perhaps we can work on that later. But first, Homebrew." Because as much as Bilbo enjoyed kissing Thorin, he knew he needed dinner at some point in the evening. So did Thorin.
