And that should have been the end of it. Bofur was good at forgetting people's secrets; it was one of the reasons people liked him. Dwalin had breasts, and it didn't matter, and it wasn't his business.
Bofur knew plenty of secrets, and he was good at putting them out of his mind. He'd managed to forget the look of grief in Fili's eyes when his younger brother had crept out to kiss the milkmaid at that first inn the company stayed at. He'd forgotten that the reason Nori had joined them was because Thorin gave him a choice between adventure and prison. He didn't remember that Bombur still wept for his dead wife on the darkest nights. He should be able to forget this one, too.
He knew why he was having trouble with it. It was a petty thing, and he disliked himself immensely for it. Dwalin was Dwalin, whether he had breasts or no, but the pleasant fantasies that Bofur had once been able to indulge in now hit a screeching stop at the intersection of reality. It had never been more than idle attraction; everyone knew Dwalin took no lovers. And if he had, he would be able to look higher than a poor miner to whom Erebor was only a legend. Dwalin's family was highly placed in the Longbeard clan, and the renown of his warrior status had earned him several offers of alliance from neighboring clans. It certainly didn't hurt that he looked like a dwarf out of legend, all that a dwarf ought to be.
Well, now he knew why Balin had refused them all on his brother's behalf. Bofur had thought it was because of Erebor, or perhaps because Dwalin was holding a torch for Thorin. But no.
It shouldn't matter. It shouldn't bother him. Bofur grit his teeth.
He'd never had a chance with Dwalin, and it hadn't bothered him at all; it was just nice to have someone to fantasize about. Bofur liked dwarf women just as well as he liked dwarf men, and it shouldn't matter that his fantasies had been about a comforting weight at his back, a hard cock within him, and muscled arms holding him trapped in their embrace. Only one of those things was no longer real, and it shouldn't ruin the rest, and it was just a fantasy. He should be able to let this go.
