I'm obsessed rn with the idea of Thor thinking Loki just wants a close brotherly relationship while Loki is taking advantage of him and making him do more and more sexual things under the guise of "being a good big brother" like, "Come on, why don't we shower together? I think it's a good bonding activity, and you wash me better than I do myself!" And "Can I sit on your lap? You're so comfortable and warm. No, it's not weird, we're brothers! I just want us to be close again." And whenever Thor gets uncomfortable, Loki bats his eyelashes and pouts, "Please, Thor? I just want us to be close again, like how we used to be?" And "Aww, but we used to share a bed when we were kids!" And Thor crumbles every time. Thor of course, is so unbelievably horny and stupid with adoration, but is in such denial he just says he wants to be a good big brother so he does whatever Loki asks of him (and gets a major hard on every time)
And Loki escalates it (of course) and starts making Thor give him hand job, then blow jobs "You do it better than I do, please? I won't tell anyone if you don't!" And then they're just fucking and even then, Thor is in complete denial.
And Loki pretends he's just using Thor for sex until one day, he comes out of his own denial and confesses his feelings to Thor, which causes Thor to snap out of his own denial as well and they have a sappy make out session after confessing their love to each other
