As it says above this is a site with fic recommendations for people (mainly) over the age of 18. Fandoms I read currently include just Harry Potter and Criminal Minds. My age limit/rec is based on my preference for fiction with sex and/or violence.
The next thing I need to underline is that I own next to nothing - Harry Potter and Criminal Minds (including but not limited to all the glorious characters) are NOT my property and to find out all the people and companies who do own you have to do the googling yourself. Unless of course if someone high and mighty informs me that I do in fact need to put up a list of those fortunate ones, in which case I'll do it.
Before starting with the rec lists, here's a quick overview of the things that rock my fictitious boat:
I try to steer clear of wips and I'll be sure to only rec completed works. Even though this very site is at the moment very much a wip.
Mistletoe by Forever then some
I read this a long while ago and remember it being brilliantly funny. It's set in Christmas time. Snape has his aunt visiting while for whatever reason Harry is also stopping by at Spinner's End. Snape convinces Harry to pretend to be his boyfriend for the benefit of his aunt. A good premise for a humor/romance slash fic, right? The only trouble is, it's been apparently taken down off the web and my only hope of finding it, would be that someone saved it on their computer and would be willing to email it to me. So, if you have it or know who does, please please please leave a comment.
Live and Die This Way by JustJasper
In this AU fic Morgan is a transporter of illegal goods. He prefers not to know what he's moving but it's kind of hard to ignore the thumping sound coming from the trunk.
Rating: explicit, warnings: noncon, violence, sex trafficking
Undercover by cr8zymommy
Reid and Morgan go undercover pretending to be a gay couple to lure out an unsub who kills gay couples in a college town. Reid tries to hide his attraction from Morgan but that's not his only secret.
Whole time I was reading it I couldn't wait to recommend it. There's plenty of good Reid-whumping. Only trouble I had was with how many times Morgan carries sleeping Reid out of the car and undresses him for sleep - it started to feel sort of infantilizing. That said, the other stuff balances it out.
Rating: explicit, warnings: violence, past noncon, domestic violence, Reid/OMC
Time by cr8zymommy
I'm putting this under Reid/Morgan but if you're looking for erotica, it's not in this story. Reid is kidnapped and kept for over a year by a sexual-sadist before being found. The BAU team struggle to help the traumatized doctor. Time is a heavy fic to read, the torture is brutal and the trouble of recovering from the experiences is achingly well described. I think binge-reading this is almost as good an idea as binge-watching Hannibal - breaks in the company of Friends or something similarly light-hearted is warmly recommended.
Rating: way high for: violence/torture, noncon, Reid/OMC, Dom/sub (noncon)
Salad Days by nebula99
Practically a pwp oneshot. Reid and Hotch run into each other while still in college, AU for the age difference. Hotch is in a fraternity and Reid's easy to pick on. Results in dub-con. Adults only or NC-17.
Red Mist by nebula99
Starts with domestic violence (Reid/OMC), goes into a bit of hurt/comfort (Reid/Hotch slash).
White Lies by cause.A.scene
This is a casefic with some violence (not too bad) and h/c. Reid gets caught up in the middle of an attempted bankrobbery and tries to do something about it. It alternates between Reid's pov inside the bank and Hotch's pov on the outside.
Icarus Falls by AhmoseInarus or hatochiisai
In this casefic Reid has to go undercover as a highschool kid. Rated NC-17 for violence and non-con. We have a clever!Reidbut also angsty/gets-caught-up-in-the-case!Reid. There's not that much of the rest of the team.
The title has a link to the fic on Fanfiction.net but their policy on mature content means that the noncon scene cannot be read on there. So here is a link to the complete version.
The Mind Is A Treacherous Thing by Eligent
"The Berkview Institute for the Criminally Insane is hell on earth and Reid's new home." To say more about the plot would ruin part of the fic for you. Rated T, drama/angst, includes violence.
College Sweethearts by TheKnittingLady
The team gets a case that links with Reid's past. Almost 20,000 words, hurt/comfort, angst, lots of violence (abuse) but I'm almost certain the rapes aren't described in much detail (again, been a little while since I read this). This fic is definitely NOT for those faint of heart, NC-17 and not pretty (well there are sweet moments too, Reid/OFC romance). The story has a sequel, The Long Road to which mostly the same warnings apply but there's more h/c.
Hunger by Eligent
33,700 words. "When someone is coming for one of their own, the whole team hurts, which the BAU painfully learns as an unsub seeks revenge in the deadliest way." Reid and Morgan are affected, the fic's Reid-centric. Drama/angst (insecurity), Reid's traumatised and can't eat. Rated T for some violence.
Secrets Are Walls That Keep Us Alone by procrastin8or951
I don't generally like to read Marauder fics but the subject got me in. What we have here is a story in which young Sirius (age 16) develops an eating disorder as a result of parental abuse.The fic isn't awesome but it's good and I found Sirius' issues believable. Warnings: Contains eating disorders, abuse, violence, depression, minor language, mention of drugs.130,000 words divided into 74 chapters. The abuse got kind of much even for me (okay, I'm not overly callous, I hated watching Sin City) so the warning for violence shouldn't be dissed.
Thirteen by minnow_53
In this AU fic Remus is with Sirius but he's also a paedophile into little girls. It's well written, chilling rather than sexy. An interesting read that differs quite a bit from the mainstream of HP fanfiction, quite realistic. Warnings quoted from the author: AU, chan, dub con/non con, het, demonising of a beloved HP character... This is far from being a fluffy R/S story, and some people could find it offensive.
Seeing Through a Monster by Bonomania
Dumbledore has Snape fetch Harry from Privet Drive as Vernon's abuse is about to cross another line. Misunderstandings, hurt/comfort, angst.
A Year Like None Other by aspeninthesunlight
Gen, hurt/comfort, torture, blindness, adoption, self-harm, angst, magical theory, T
Harry receives a letter at Hogwarts from the Dursleys that starts the ball rolling. This is a novel length fic with a lot of good conversations between Harry and Snape.
The Long Way Down by Alley B
I very rarely read het and this one has Snape/Hermione as pairing. The reason I took up with it is the premise - the author had read Margaret Atwood's The Handmaid's Tale and placed it in the Potterverse. In case your unfamiliar with the novel, let me just say it works perfectly as another what-if-Voldemort-won scenario. NC-17 for graphic violence and noncon.
Blood Magic by GatewayGirl
Blood Magic is a severitus piece. Rating recommended by the author is for over 15-year-olds because of some drug use. So, another fic that doesn't really go so well with my list of favourite kinks. What kept me with it even though it's a bit slow is Harry growing up emotionally some. There's plenty of good dialogue; it's kind of refreshing to have a fic that doesn't treat Ron and Hermione as dead weight, grudgingly dragged along as is often the case if the author enjoys writing Harry and Snape.
A Black Comedy by nonjon
Rated M or NC-17 for sex, drugs and rock'n'roll the fic is accurately titled. It kept cracking me up even though it sometimes gets a bit technical around Harry and Sirius' burglaries and what not. Seriously though, between all the angst of most of my fic recs, don't you just need something a little lighter? Plenty of class A banter included.
"Two years after defeating Voldemort, Harry falls into an alternate dimension with his godfather. Together, they embark on a new life filled with drunken debauchery, thievery, and generally antagonizing all their old family, friends, and enemies."
The summary by author combined with the warning will suffice: Even a brief stay in Azkaban for Harry will be disastrous. Graphically described well-written sickening non-con oneshot, NC-17.
Pleasures of the Flesh by Lokifan
Lucius Malfoy has Harry at his mercy in the manor. And this is what I wrote after first reading it: "Completely awesome! This is the type of well written absolutely fantastic description I've been searching far and wide for. Sometimes it seems to take so long to find these little gems in the midst of all the un-beta'd fics with lousy characterisation that when you hit gold it's an almost instant orgasm." NC-17, non-con, bondage, oneshot
Detention Served by Amanuensis
Snape gives the 11-year-old Harry detention NC-17 style. Warnings: non-con, chan, PWP oneshot. Worth recommending for those who can stomach the genre.
An Innocent Question by FalconLux
Here we have an adult Harry coming back to work at Hogwarts and being recruited to help out Snape. A sweet oneshot with a T rating. Some nice screaming - my favourite bits in OotP were the screaming matches between Snape and Harry.
Eye-Opening Revelations by DelusionalGrandeur
Forced marriage is Dumbledore's plan and Harry and Snape are the intended parties. Rated T, oneshot, humour.
Peripheral Vision by Alexandra Dane
The war is over but not without a cost - among others Harry and Snape have lost their sight. Staying at the rehabilitation centre for witches and wizards, the two get along rather well. This fic of 27,000 words consists mostly of truly excellent dialogues and the whole feel of the thing is fairly grown-up. I'd give it a T-rating for some language, action-wise it remains PG-13 in my estimation. In short, a perfectly lovely story with some hurt/comfort.
What He Wants by debchan
Written from Snape's POV, set after OotP, strong R or maybe NC-17 but not very graphic. Snape is enlisted to stay with Harry at 12 Grimmauld Place in the summer after fifth year. Very dark, well written.
The Dreaming Spires by DementorDelta
This one is best prefaced as briefly as possible to avoid spoilers so here goes: Harry is 20 or older, POV is Snape's, rating is NC-17 for sex but not PWP and it's not a heavy, angsty read even though it's not really a humour fic either. If you like adult SSHP you should read it.
Night Watch by mia_ugly
Voldemort has won but Harry cannot be safely killed, so must be kept a prisoner under constant surveillance. Wonderful angst while Snape spends his nights on guard duty. Both POVs, NC-17 for slash.
If You Are Prepared by Cybele
Quite possibly the most perfect SSHP fic there is. Written alternately from Harry and Snape's POVs, Cybele makes them both wonderfully sarcastic while distinctly different from each other and as close to what Rowling created as possible considering it's a Snarry. Starts after Harry's fourth year, Snape is conscripted by Dumbledore to stay with Harry over the summer to keep the boy safe and teach him.
Rating: NC-17 for in-detail chan, also character death, angst, hurt/comfort.
It's seriously a wonderful read all the way through. If you are the type to blubber over fictional characters, you might be interested to know that for me, the last two and a half chapters were a total sob-fest.
Tea Time by novembersnow
This is a set of ten 100-word Remus-centric drabbles. There's Remus/Sirius slash but it's PG. Tea Time is sweet, I'm a little bit relieved to notice that I do actually enjoy reading nice stuff too, not just torture.
A sweet teenage Remus/Sirius, some 28,000 words, T or NC-17 for couple of scenes for sex.
Another sweet and well-written Sirius/Remus, PG-13, 8,000 words.
Whore by anonymous
A truly well written dark, long (141,000 words) fic whose warnings you should really take seriously. There's way underage non-con, a fair bit of violence, attempted suicide, some self-harm, murder, forced prostitution. Perhaps from that you can surmise what the summer job Uncle Vernon has procured Harry for his first summer back at Privet Drive is. If you expect your sensibilities able to handle this, you'll appreciate the original male monster the author has created. And there is too comfort to balance the hurt some, including but not limited to some consensual sex.
Fatherhood's a parody fic where Harry and Snape discuss fic clichés, such as Snape being Harry's father and mpreg. Only read the first of 9 chapters (altogether 10,000 words provided it won't be continued) so far but I loved the bantering. ^_^ Rated T.
your darkness has found a kindred spirit by oddlygay
If you're looking for an NC-17 slash fic to read that goes with listening to Sia's 1000 Forms of Fear album this is it. It follows Alex Mahone through I'm assuming all the seasons (I seem to recall dropping the show somewhere along the line). It's a perfect angst piece with the first pairing being Alex/OMC and the second Alex/Michael Scofield.
