Here's a few of my favourite fics! This is by no means comprehensive, and I'm sure I'm missing some absolute bangers, but, well, these are what's in my bookmarks folder currently. This list will be continually updated!
[bound with everlasting chains] by ivelostmyspectacles; Currently unfinished at 35 chapters, but damn, what a ride it is! Summer is an expert at writing both thoughts and dialogue in perfect character, and who doesn't like a good slow burn with action scenes??
[His Love to guard me through the night] by ivelostmyspectacles; There are a bunch of fics about that last night before the Unknowing, with Jon and Tim sharing a room, and they all depress me SO MUCH but I KEEP READING THEM but this one is the one I love the most. They hold hands, man ;-;
[sleeping in] by ivelostmyspectacles; ONLY ONE BED! ONLY ONE BED! I requested this from Summer and HOO BOY did she deliver in spades. I think my favourite manner of JonTim is that season two/season three anger, when they really can't stand to be in the same room anymore (well, Tim can't. Jon has other shit to deal with, lmao), but for some reason, they have to work together, and oh noooo feelings come out. It is so tasty and wonderful and sad and this fic just hits that delightful nerve to me. Also, I love these lines in particular:
"Tim says nothing, just eases himself back into the pillows, and folds an arm beneath his head. Jon thinks maybe he looks a little perturbed as he stares up at the ceiling, but then Jon looks away, distracting himself by staring up towards the ceiling himself.
It's not a very good distraction. It's a very boring ceiling."
Just tickles me, it does.
[just surrender, cause you feel the feeling taking over] by ivelostmyspectacles; Ah, yet another one by Summer... look, she just writes some of the best JonTim there is. This is another one inspired by something I drew, of a Stranger!Tim whisking Jon away on a stage amidst fire and ahHHHHHH what an amazing gift and companion piece! I ALSO very much adore a dark end JonTim where Tim is all mannequin-ified and lovely and terrible and entranced by a terrified Jon... so lovely indeed. And this fic gets right at the awful heart of it.
[socks & stories] by fav_littleleaf; Oh everything about this fic is so tactile and cozy, and it makes me want to desperately cuddle someone close in a warm, soft bed (and I don't even like cuddling!). Just the sweetest thing in the world (and, a little creepy. Maybe more than a little. But also aw-inspiring).
[The Meowgnus Pawchives] by SixofOne; God I adore these just-about-canon-compliant-until-they-aren't fics. This story is so cute and funny and utterly charming, and then there's a cat! And then there's a kiss! And it makes me melt because it feels like I'm reading a perfect episode of TMA if everything I ever wanted to happen actually happened.
[swallowed, into the belly of the whale] by kittiwake; This is somehow one of the most perfect interactions of Jon and Elias I've ever read, and it's also got fisting in it. What a world! But in all seriousnous this is done in such a way that it makes so much sense, in terms of power and control and both their characters, and is incredibly cerebral and sexy. It's delicious and heady and I want to dunk my head in and consume every single interaction between the two that we don't see.
[Birthdays of a Beholder] by YellowFlannelFrog; A gentle and quiet read on Peter and Elias' relationship, from false marriage to actual love. I really like the concept of them getting married for convenience's sake, and how Elias is just so interested in what he can't read - Peter, namely, and all the mysteries he contains. The back and forth of birthday questions is such a fun little thing between them, and so perfectly in tune to who Elias is - questioning, needling, wanting... but patient, contained. One of those gloriously long one shots where the time flies by as you're reading.
[heaven-sent T.N.T] by sandpapersnowman; Aw yeah, probably the first compulsion/confession fic I'd ever read! Just so perfectly sexy but also very very sweet and somehow in-character.
[the Mortifying Ordeal of Being Known] by DamagedDolly; Just an incredibly tender fic revolving around a Jon who learns that he likes to regress, and his and Martin's sweet romance. It's all very cute and slice-of-life, and honestly one of my favourite things is the bond Elias makes with him and Martin - it hits the JonElias shipping part of my soul despite them having no romance; the caretaker aspect is, apparently, good enough for me. I also like how we slowly learn everyone's thoughts on Little-ness and how they relate to it - the author does a great job uncovering their philosphy on the whole thing. And as of posting this here, this fic is 199 chapters long and still going! The author generally updates during the night, so when I wake up in the morning I get a little bite-size chapter of pure cuteness, and it just makes my morning every time.
[have some sympathy, have some taste] by fatal_drum; UGH, the primo PaterMartin... god, when I first fell into this pairing I must've read it like twenty times. I adore fatal's way of writing both characters, Peter charming and distant, Martin hunkered down but still caring. It's a quiet storm of a story, with so much character background laid throughout it. Lovely stuff.
[bacchanalia] by Prox (Amber); Oh this one is so dark and indulgent, yet every line is so perfectly in character with Peter and Martin; Peter doing whatever it is he wants with cheerful aplomb, Martin's weariness and reflexive politeness. And the caretaking at the end! Love it when a villain is so tender and kind and completely ignorant to an unwilling subject.
TimMartin - [you were a kindness] by Wildehack; What is it with fanfic and having some amazingly written porn also end up being like the saddest thing you'll read in a month? This is that! FUN!! Maybe don't read this one if you want good times only but whewwww make sure you do at some point, because this fic is so tenderly written and in-character and it makes me weep for Tim and Martin both.
TimMartin - [Second Choice] by Arazsya; It's December as I'm posting this, so it being Christmas-themed hits the spot. What a gentle little fic - it doesn't say away from Tim's frustration or Martin's desperation, but as you read on the compatility of the two come together, and you remember that they /were/ quite the duo in earlier seasons.
EliasMartin - [draw a white chalk baphomet] by any_open_eye; EliasMartin is a /delightful/ pairing, especially when Elias considers Martin an object to be treasured and used to his full purpose - it ain't right but, you know, in terms of an evil entity taking notice of you... it's not half bad! I love how matter-of-fact ELias is in this one, and the rules that the author has created to make the scenario work; if TMA were higher rated, it wouldn't be out of bounds to see it be a part of canon.
The TMA fandom has a ridiculous amount of amazing fics, so, here's where I'll be keeping the ones my mind continually returns to.
