This will never be complete. Ratings vary, but will most likely be NSFW and NSFW means Explicit or some Teens and up ratings on AO3. My own fanfics are here and you can leave me a prompt or a rec request in my askbox. I’ll update this page as often as I can (which literally means: when I sort through my bookmarks), but you’ll be fine. :D

UPDATED: May 5, 2013


THE AVENGERS

Firsts and Lasts by Simmysim (NSFW) - Basically a PWP involving Steve’s old uniform and Tony’s kink for Captain A as a child.
Full Body Workout by Nix (NSFW) - Hank gets a little distracted in the laboratory and Tony and Steve get to suffer (?) the consequences.
It’s the Simple Things by Onewayfreak - Oh, Steve just appreciates Tony’s ass.

Borderline by mdevile (NSFW) - Fisting.
Right off the Rails by autoschediastic (NSFW) - Spanking. No penetration.
Apple Bottom Jeans (And Other Love Songs) by gyzym - Literally Tony trying to seduce Steve by singing in the shower.
The One with the Teenage Hormones by cherryfeather - Steve and Tony de-aged into teenagers. Fluff. Making out. Coulson finds them.
5 Times Steve Attempted to Make Tony Blush, and the One Time He Succeeded by sororexitium - Fluff~ Also, there’s some delicious Steve-seduces-Tony-but-doesn’t-quite-know-he’s-doing-it plot.
The Road to Hell by colourexplosion - AU! Pepper gets promoted and Steve becomes Tony’s PA. 
Teenage Dream by shinkonokokoro (NSFW) - Tony gets de-aged, turns into a teenager, and gets into Steve’s pants. Then forgets all about it when he returns back to normal.
Physics 101 by shinkonokokoro - Tony’s a Physics teacher and Steve needs to take his class for gen ed. Basically AU and fluff all around.

I don’t want you (to smile to anybody) by Mizzy (NSFW) - How do you describe the pang in your heart from seeing the one you love be with someone who looks like you? Total shit. It broke my heart and stitched it by hand all over again.
Ready, Fire, Aim by gyzym (NSFW) - There’s no “I” in “Avenger.”
Tomorrow Belongs To Me (NSFW) by valtyr - Steve wakes up in the 21st Century. He doesn’t think much of it, and it’s dubious about him. He meets a Norse God, joins a superhero team, and feels terribly awkward about the whole momument at Arlington he’s rendered obsolete by not being dead. Meanwhile, Tony is trying to make his mark on history by being the man who finally drove Nick Fury over the edge.
Team Building Activities by valtyr - Fury’s a beautiful princess. Clint’s plotting a Communist revolution. Rhodey’s not sexy. Wall-E’s not a documentary. Clint’s not gay but he does give a great blowjob. This fic is not an AU.
Honey, I Can See The Stars (NSFW) by twentysomething - ”The most he’d ever cared about anything remotely related was his uniform, which, beyond the stylistic, was pretty necessary. But now his suit comes from a lab far more advanced than the basement of a Brooklyn antique shop, and the only decision he really gets to make is if his pants are too tight. (They were, but he doesn’t really think they changed them. He doesn’t know why, but he thinks that might have been on purpose.) That being said, he doesn’t know what he’s done to deserve the double take Tony gives him as he walks in the room.”
(First Impressions Are) A Work in Progress (NSFW) by porthos - Tony has a point system for the times he can get Steve to be less than perfect.
Bulletproof by foxxcub (NSFW) - At age fifteen, Steve Rogers had been in love with Tony Stark. By age twenty, he’d (mostly) gotten over it. And then he promptly became Tony Stark’s fuck buddy.
A Kiss To Build a Dream On by xDinahQueenx - It’s the perfect reason for Tony to get a kiss from Steve, without repercussions from just telling him- things don’t quite work out the way he’s expecting.
Community Service by valtyr - Matchmaking is harder than it looks.
Scale and Perspective (The Technicolor Remix) by destroythemeek - Tony had always appreciated Steve’s art, but he didn’t realize Steve’s art had started appreciating him in return.
Idle Rainbow by valtyr (NSFW) - Tony knows that worthwhile things take hard work and sacrifice. Steve’s not so sure.

An Offer of Kryptonite by bendingsignpost (NSFW) - Use of a phallic and frankly very suggestive pastry in getting Sherlock into bed. Or is it the other way around?

Please God, Let me Live by flitterflutterfly (NSFW) -  When John Watson found himself facing an AK-47, on his knees and hopeless, he said the only thing he could say. But, while God did let him survive, living was a completely different matter. And for a Sub without a Guardian in London, well that was a harsh matter indeed. 
Ninth by Zeta Sigma - John’s jaw dropped as Sherlock Holmes touched his bow to the strings of his violin and began to play… AU story for the BBC show Sherlock. Feedback is greatly appreciated. Hints of depression, eventual JohnLock and violence. 
The Sum of Us (Mostly Calculated by Everybody Else) by Linpatootie - John decides to come out. More or less. Not that he’s gay or anything. He’s just bumming his flatmate.
Five Times by strangegibbon (NSFW) - A chronicle of Sherlock’s formative lap related incidents. Slash, eventual JohnxSherlock.

Don’t Be Dead by je-suis-a-toi (NSFW) - Set after Reichenbach, John never truly believed his best friend was dead, but of course after they meet again and hug briefly, he will punch him for making him wait so long.

A Cure for Boredom by emmagrant01 (VERY NSFW) - They’d never talked about sex in the year they’d known each other. Well, that wasn’t quite correct: Sherlock had never said a word about sex; John had bemoaned his personal dearth of it on many occasions.
All the Way by SailorChibi (NSFW) - Sherlock shaves. All over. John is fascinated. note: This is hot.
Expecting the Unexpected by sweetomegachild (NSFW) - Expecting a child is always an exciting and challenging time. Expecting a child as an loving Alpha-Omega couple is even more of an adventure. Good thing John and Sherlock like adventure. note: One of the fics I love the most. Yay omegaverse!
Withdrawal by AGirloftheSouth (NSFW) - John goes away for 5 days and Sherlock has some separation issues. PWP.
Many Mornings After by lene-anschutz (NSFW) - Neither of them can remember what happened last night, but it can be quite easily deduced. John comes to some realisations and Mycroft wins a bet. 
I’m Not Actually A Pervert by dorothydonne (NSFW) - John Watson isn’t actually a pervert. Really. He’s just a bit sexually frustrated. Honestly, he’s never done anything like this before.

One night, though, John points to a couple that turns out to be sickeningly in love, faithful, completely happy together - boring, in other words, expect that as Sherlock deduces things he realizes that the tells he is describing also describe he and John.

Two Facts by SailorChibi - When Sherlock and John first mated they decided that they didn’t want children. But now Sherlock’s pregnant and it’s threatening to tear his world apart. He knows John will leave him once he finds out, but how can he decide between his alpha and the child he didn’t know he wanted?
 

 


Holmescest

Headmaster by chasingriver (NSFW) - Mad porn. Probably my most favourite out of all the Holmescest fics out there. It’s amazing.
Middle Ground by Boeshane42 (NSFW) - PWP and an asexual Sherlock. 
Crazy Little Thing Called Love by goje (NSFW) - His little brother had the eyes of their mother, and when Sherlock looked at him now, Mycroft could see a younger Mummy gazing at their father.
The Maths is Done by lucelafonde - Kind of AU. In a world where everyone is born with a number visible on a random body part, a number which only exists twice - on yourself and on your soulmate -, the Holmes brothers have managed to never see each others. What happens when that changes? 
Fantasy by narsus (NSFW) - Mycroft’s fantasy involves Sherlock wearing a Harrow school uniform, and being fourteen years old. Not that either of those things bear any resemblance to reality.
Breaking Strain by lucybun (NSFW) Mycroft and Sherlock have to wait for each other.
Let’s Have Lunch by Blame It On My ADD (Baby) - Mycroft has an eating disorder and Sherlock ends up helping him through it, just like Mycroft helped Sherlock through his drug addiction.
The Synchronization of Heart and Mind by beingbaz (NSFW) - The first time Sherlock kissed him was a shock. The fact that he wanted to be kissed by him again felt worse. But that didn’t stop the want.
Cake by FastIce - Sherlock hates being bored. He loves to experiment. Lastly, as Mycroft put it: He does love to grandstand. At eight years old, Sherlock Holmes was already showing signs of his rather eccentric personality - much to his family’s amusement and chagrin.
