Imagine getting really drunk at one of Tony' s parties (or sleepy because it's late, if drinking isn't your thing) so they set you up in a room to sleep it off. It ends up being Loki's room and at first he's annoyed seeing someone in his bed but upon realizing it's you, his face softens and he tucks the blanket in properly (burritos you) and stays to make sure you're fine. You wake up and groggily convince him to cuddle you, happily falling asleep back in his arms.
