Looking for a fic where Loki is punished/controlled by marrying/binding to Thor. He hates it and hates Thor even more when he realizes that Thor loves him and wanted them to marry all along. But in order to complete the ritual, they must consummate the marriage and Thor says something along the lines of "I don't want to rape you, but I will not let you die, beloved..." Cue lots of angst. I think there's a happy ending though.
Thanks in advance!
