5+1 fic of 5 times the Avengers noticed Thor and Loki being uncomfortably intimate, touchy-feely, or just... having those long emotional moments of staring into each other's eyes, and told themselves for the sake of their own sanity that 'it's just a cultural thing' and 'they have a complex relationship, and Thor's just trying to show his baby brother that he loves him'
and the +1 time where Loki walks out of Thor's room and casually joins them for breakfast looking VERY freshly fucked.
