"Was wondering if you could rec any fics where arthur is merlin's slave? Either canon or modern au bdsm :)"
Lie Back and Think of Camelot
The story starts as it is within the show, but then through some occurrence, Arthur lands into an AU where he is Merlin’s sex!slave. Merlin lives within Camelot, but is awarded a high position at court due to being a powerful sorcerer. Bonus points for a) Arthur not knowing about Merlin’s magic until then, b) Merlin being puzzled at Arthur’s sudden rebellion in bed, but being quite prepared to teach him a (kinky) lesson, c) Arthur enjoying it all in spite of himself, especially Merlin’s tendency to snuggle (I’d love it if Merlin had personality and control, but would also be a nice - fair - kind of guy, and much inclined to protect a mouthy!Arthur, because even in an alternate universe, they’re two sides of the same coin), d) including the bit where they return to the ‘normal’ state of affairs, and in spite of finally being in control of himself again, Arthur kind of misses the attention/care he received from Merlin.

dreams for wings and wanderers
Summary: Dragons are feared and mistrusted throughout Albion, and there are very few of them left in Camelot, for Uther’s long campaign against magic also included hunting down all the dragons in the wild. Now, Camelot is recovering from the invasion of Cenred and Morgause’s army. Prince Arthur is the one in charge, and Merlin finds out that his secret regular visits to the covert haven’t been very secret at all. There’s a great deal of manly bonding with the Knights, inquisitive dragons being inquisitive, and a record-breaking number of near-death experiences for Merlin. And this is before he gets his very own dragon. (A Merlin/Temeraire fusion.)
