Hi! I'm looking for a fic where Merlin has to try hold back from using magic when he and Arthur have sex but Arthur thinks he's in pain. I do remember that Merlin's magic creates like flowers/vines growing up the bed posts? I feel like I remember Arthur seeing this and being in awe. Whenever I try to remember the fic all I can think of is: "and that's when he notices the flowers (vines?)". Set during canon era, more than likely when Arthur is king. Pretty sure their relationship is developing not established. I've gone through all my bookmarks (even tried to decipher the deleted ones) but can't fine it anywhere. Would appreciate any help!
