Chapter Text
fíli didn’t notice it, not at first, and he heavily doubted thorin noticed it as well, with the way thorin’s hips were slamming against his and the noises he made with each thrust.
the door to his uncle’s room opening, and a head leaning into the room. initially, fíli thought it was his mother, to tell them to quiet down, or that they had woken kíli up.
instead he saw kíli, watching them with curious, wide eyes– and oh, the moment their eyes locked, he felt his cock throb, almost painfully.
fíli knew that kíli understood there was something… more to his relationship with their uncle. fíli also knew there was more to his relationship with kíli, and that kíli felt the same, even if he didn’t quite understand it yet.

“do you need something?”
“no, i just– well, i heard noises and wanted to see what was going on and, then, um, seen… this,” kíli stammered out, hand still on the door.
fíli took note of the flush on his little brother’s face and of the way his thighs were slightly pressed together. he had to have liked what he was seeing, given that he stayed and his body was reacting the way it was, even if he didn’t know it yet– right?
