He couldn't help but chuckle a little when he heard Bilbo's words, because he had a feeling that would have been the hobbit's response. It felt like the two of them were getting more and more in sync with each other, and that made Thorin very happy. Thorin couldn't think of another person that he felt more comfortable with, and he was beyond happy about that. It was nice to feel like he could let his guard down with someone in every way possible.
"Yes I did, but can you blame me?" he replied, his tone still in the same teasing manner. But there was also that hint of a husk to his tone, and a hint of lust showing through his eyes. It was very clear what he needed and wanted from the Hobbit in that moment.
"I thought so as well" he added, a small smirk now showing through on his lips as he looked down at Bilbo. "And I am honored to be that one". With that he leaned in and kissed Bilbo passionately on the lips, conveying every ounce of love and desire that he was feeling in that moment into that one kiss.
