A Supervillain’s Guide to Getting Married (слэш)

Written for this prompt on Avengerkink: "Even though there's the frequent battles with the Avengers, and his plans are always being thwarted, Loki likes it on Earth. He doesn't want to leave! But Odin (and Thor) rather want him back in Asgard. Loki decides it would be a good idea to marry a local, and have an excuse for staying put. Maybe he tries meeting some new people, but they don't interest him much. Better to stick with the people he knows (and would never admit to maybe kind of respecting a tiny bit). So Loki decides to marry an Avenger."
