mitchellcest headcanons

i recently rewatched the mitchells vs the machines, and the idea of aaron and katie as an incest ship has been living in my head rent free ever since.

i certainly thought about it when i first watched the movie around the time it came out. i thought it was cute, in a really messed up way. i was at the time very active on "proshiptwt" and i certainly saw lots of suggestive art works of the two. one thing is for sure, porn artists are very quick to jump on the last trends. it's a little bit impressive.

but that's besides the point. the works certainly made me think about the ship a bit more sincerely, and now i have a few thoughts on it.

my interpretation of the ship is aaron has a cute, innocent crush on his older sister, but he isn't fully aware of the implications of that, or that he's even attracted to her that way. i think he would be the type to get flustered around her, or maybe a little shy, but not really know what any of that means. why would he feel weird around his sister after all?

if there's something i'm a sucker for is the idea of guilty predator, and that's what katie is to me. she adores her little brother, and she enjoys the attention she gets from him, and at some point she realizes maybe she likes it too much. maybe she even feels jealous of aaron's crush on abbey, and it makes her feel horrible and extremely worried about what this could potentially mean.

i'm not entirely sure how i imagine their "relationship" starting just yet. i'm still figuring that out, but i'm thinking maybe aaron innocently kisses her one time, and it sends katie over the edge. all these feelings, these urges she'd been trying to repress for his sake are suddenly out of control, because now that she's had a taste of it she can't bring herself to stop.

so she keeps encouraging her brother's behavior, leading him on and telling him to not tell anyone, and of course he listens because he'd do anything for her.

aaron is confused about the things his sister does to him, but he's happy they get to share something special and that she seems to enjoy it so much. meanwhile katie feels sick and like the worst person on earth, but she's so addicted to it, she can't stop no matter how guilty she feels.

i think their relationship would start relatively tame. kisses, cuddles, things like that. she wouldn't want to take things too far, or that's what she tells herself at first. but she's not strong enough to hold back for too long, so their dynamic does become sexual.

aaron would feel strange. he likes the affection he gets, but it feels like too much. as long as it makes katie happy though, he won't complain.

i love the idea of katie teaching him how to eat her out, and aaron being so confused, but very eager to please her. he kind of sucks at it, but the inexperience arouses her even more.i also enjoy thinking about the secrecy of it all. as far as anyone, including their parents, can see, katie is a nice, older sister. but when no one is looking she's getting her little brother off. i love the idea of her sneaking into his room at night to "play" with him and having to close his mouth with her hand so no one will hear his noises.

there are probably typos all over this but i'm too tired to check and edit. i just wanted to talk about shotacon incest before bed.
