Arthur and Morgana have an unspoken deal. One night everything changes.

Merlin is anxious but cannot tell Arthur why. Arthur is certain he knows the reason. He is wrong. Series One, Episode Twelve "To Kill the King" - Missing Scene. Rated 'M' for a reason. Don't want slash? Don't read...

Merlin falls down and Arthur must take care of him. PWP. Smutlet. Prequel to Waking Up Merthur. Original request by: NikkiLizzie (followed by others ;p)

When a healing spell to save Gwen from a life threatening fever goes wrong, Merlin finds himself temporarily trapped in her body. But whilst in the Queen's body, will he be able to resist Arthur's sexual advances? Does he even want to resist? *Gender Bender* (Merthur-sort of)

John overhears Mycroft belittling Sherlock's being gay as "just a phase." So he snogs Sherlock in front of his brother, apologizes for insisting they stay in the closet, and pointedly tells Mycroft to run along. Only problem is, John's not gay, and Sherlock's got no experience with any of this. For once, the consulting detective is completely out of his depth.

In the weeks that followed his father's death, Arthur felt dead inside. Though his loved ones tried their best to help him, it was Merlin who knew exactly how to make him feel alive again. Merlin/Arthur Slash

When Arthur and Merlin stumble upon a mysterious cave, their lives are changed forever. A truth seeking spell causes them to swap bodies and unless they can solve the riddle and find the answer to a question Arthur didn't realize he was asking, they will be stuck in each other's bodies forever. Oneshot Magic Reveal Arthur/Merlin Merthur

A tangent from Camelot Inc. What would happen if Arthur gave Merlin permission to have the druid boy, Mordred? What would he do if he promised him that it was ok and then left town for a couple days? Merlin is unable to resist the burning that is Mordred he is quickly taken beyond any pleasure he has ever known. M for smut Merlin/Mordred Slash

When Jason discovers that he has taken Pythagoras' fancy, he's surprised to find himself looking at the mathematician from a whole different angle. Jason/Pythagoras Slash

Arthur, Merlin and Gwaine have become a lot closer recently. However, as they begin to realise and admit their feelings for one another, jealousies, frustrations and fears arise to complicate matters. Sequel to 'Falling into Madness'. Can be read as a standalone. Arthur/Merlin/Gwaine (Threesome)

Leon is the perfect knight in every sense of the word, he is noble, brave, handsome and loyal to the end. If Leon had one tiny fault however, it would be that he was just a tiny bit too composed and serious about his duties. This leads to unnecessary stress and when Merlin takes matters into his own hands to help him the result is somewhat unexpected…

Gwen and Morgana give in to their curiosity and share an intimate and sensual encounter together on a summer afternoon. Gwen/Morgana FemSlash

It's a fine line between hate and, well, other things, and they've just erased it completely.

When Merlin and Arthur get shipwrecked and stuck on 'Pleasure Island' for a week, how long will they last before they give into pleasures of the flesh and their feelings for one another? Merlin/Arthur Slash

This was supposed to be a way to save his best friend. It kind of went sideways.

With Arthur and Gwen away, Merlin decides to take advantage of the opportunity. (Merlin/Sefa, pre 5x01)

Arthur wakes up in a very precarious position with Merlin after having a very suggestive dream. Hopefully the knights will stay asleep long enough for him to resolve the situation. Oneshot. Merthur. Smutlet. PWP. Public sex. Slight dub!con.

Gwaine indulges in many vices, such as drinking, fighting and gambling... But his favourite indulgence is sex. If it were up to him, friends would have uncomplicated sex to pass the time and awkward feelings would never get in the way. However, when he falls for Merlin, those awkward feelings start to surface. What now? Merlin/Gwaine Slash

Things get hot and heavy after a night of drinking. Sexual content, Slash.

Arthur's brow wrinkled as he gave Merlin a look that wouldn't have been out of place back in Camelot after Merlin called him a clotpole, or a dollophead, and fuck, Merlin had just called him love, hadn't he?

The one where Arthur tries to court Merlin, and Merlin has no idea. (Story is better than the summary.) Less shlow-ish build. Merthur, some side Gwen/Arthur. Dash of a pining Leon. Season 4 au, Part 2 of the Miscommunications series.

Arthur absolutely hates thunderstorms, so when a terrible one breaks out in Camelot for a week, he's forced to confront a deep fear. Merlin tries to help, but ends up doing so in a way he never could have anticipated. Merthur slash, Arthur/Merlin.

The night before he marries Gwen, Arthur finds out his desire for Merlin wasn't as one sided after all, to late for it to be anything more, Arthur begs him for just one night.

When Morgana is plagued by nightmares, Gwen helps her get through the night. PWP. Morgwen.

The first kiss was an accident, but the second kiss...now that was something else. SLASH.

Of all of his many Knights to be trapped in a cell with, Arthur found himself with Gwaine. But as it turned out, Gwaine happened to be very good company. He was a great listener... an excellent conversationalist... and an absolutely incredible lover... Arthur/Gwaine Slash

Merlin stopped, however, just in front of Arthur, his breath flitting across his waiting, wanting, disappointed lips. He let out a breath, shook his head. "I'm sorry…" Merlin mumbled, not moving away from Arthur. "I shouldn't—we shouldn't—I'm sure you don't—"

He doesn't even consider he might be jealous of her until Gwaine mutters something about a green-eyed monster under his breath when he observes Merlin glaring across the table at her and Arthur at a feast one night. Merlin scoffs at him, "Hardly anything to be jealous of…!"

This takes place in season 1 after they stop Sussie. Jack is not happy that Owen used alien technology to get laid and he decides the best solution to that problem is to teach Owen a lesson. One with plenty of humiliation involved. Warning: MATURE SEXUAL CONTENTS, M/M! ENJOY! XD

Merlin didn't understand Mordred, didn't trust him but God he desired him. He'd heard the expression 'keep your friends close and your enemies closer' but this was taking it to extremes. Merlin/Mordred Slash (Mostly Smut)

There's something else in the wine that night, but whatever it was, Merlin is thankful for it bringing the three of them together. Pretty much a PWP, one-shot between Arthur/Gwen/Merlin, with a magical reveal thrown in.

Merlin has no choice but to reveal his magic to Arthur when faced with a dire situation. But how does the prince take things? How will it change their relationship and the future of the kingdom? "Merlin sighed, "He kissed me.""

The one where Merlin tells Arthur his secret, but Arthur misunderstands. (The story is much better than the summary.) Merthur, slow-ish build, Season 4 AU, a bit of Gwen/Arthur, funny.

Arthur lost a bet. That's why he ended up wearing what he was wearing and absolutely not because he wanted to. Really.

Merlin and Arthur come back heavily drunk from the tavern. Drunk sex ensues.

When Arthur overhears Gwaine talking about his sexual experiences it gets him thinking. Soon he's having a great time experimenting with Gwen and learning that his wife is an adventurous woman. One night they even involve Merlin in their bedroom antics... Arthur/Gwen-with a healthy dose of Merlin.

After a long afternoon of training with his knights, Prince Arthur calls Merlin up to his room for a well-deserved massage. Merthur smut, set some time in the first or second season.

Merlin just needs a break and a hug. No slash. Bromance. Dedicated to I love Merlin from THoC.

"Out of the way son. Or I shall thrust this sword through you as well!"/ "There shall only be one kind of sword thrusting today and that is not it!"/ Arthur decides to retaliate against his father by showing his love for Merlin. One-shot Merthur crack!fic. Porn Poetry (it will be a thing). [PODFIC] now available on Ao3: (/works/4423886)

When John goes to his girlfriend's house for the night, Sherlock is left home alone. Or is he... Rated M for the second chapter. Disclaimer: Sherlock and all characters used in this story belong to BBC and Sir Arthur Conan Doyle

John and Sherlock get stuck in a closet. Porn Without Plot.

Morgana promises Merlin she'll keep his poisoning a secret. For a price. Can Merlin pay it? Will he succumb to Morgana's seductive tactics? Will she be able to keep herself aloof? It's a sexual battle of wills with only one winner. But what about hearts? All's fair in love and war...especially in the bedroom. In the margins of S3 and beyond, what trouble could these two get into?

When a debate arises amongst the Knights over who is the best kisser, Merlin is picked to be the judge. Warning: Lots of hot men kissing!

Gwaine just wanted to offer Merlin relief from sexual frustration Arthur caused, assured him that they'd only do it if and when Merlin wanted. Surely, he told himself, Gwaine could overlook his affections and help out. Now, as Merlin moans into Gwaine's mouth, Gwaine wonders how he ever believed he could be anything but screwed-in both senses of the word. (Endgame Merwainethur)

John wakes up to discover Sherlock lurking behind his bedroom door. He decides a morning wank - a loud one, mumbling Sherlock's name - might teach his flatmate not to spy on other people in their sleep. As it turns out, though, jerking off about Sherlock is actually a much more appealing idea than he originally thought . . .

Morgana puts a curse on Arthur that's designed to send him mad within 24 hours. Merlin and Gwaine stay with Arthur in his chambers and help him through the ordeal bringing the three men closer. Will Merlin have to reveal his magic to save Arthur? Arthur/Merlin/Gwaine (pre-slash). Warning: Some bad language and disturbing imagery.

Sherlock discovers he likes getting to "deduce" what John wants. And when he deduces that John really, really wants to get off, then, well, who is he to say no?

Merlin embarrasses Arthur and Horseplay ensues, including a lot of laughing and some spanking. Something then starts to develop between the Prince and his servant. Merlin/Arthur Slash. (Includes sexy body massage)

It's been months since John's last got off properly (i.e. not just by himself), and he's more than a little frustrated. Sherlock is out of town on a case, but deduces the reason for John's mood and bluntly offers to help via text. Smutty little lemon with some humor (it's Sherlock, after all!) and delightfully explicit without actually being all that naughty, anatomically speaking.

Back in Camelot, there are standards to uphold and codes to follow, expectations that define the lives they lead. But out in the field on the eve of battle, none of the usual rules apply. (Slash)

-Complete - In my (and other's) opinion, Sherlock realizes during the course of Series 3 that he is in love with John Watson. This story is about how John realizes it too and confronts Sherlock about it. I wrote this because I was sick and tired of John and Sherlock not talking about their feelings. Hence, the story is mostly John and Sherlock talking about their feelings.

The Dragon tells Merlin it is his destiny to be by Arthur's side as his protector, not in Arthur's bed or in his heart. Sometimes Merlin hates that.

That's the thing about sexual tension that can be cut with a knife, if you have a knife you can just cut through it, right? Since Arthur doesn't allow Merlin around sharp objects, Arthur is taking it upon himself to find out for the both of them.

Sherlock believes profanity is the refuge of a lesser mind. John tries to prove that profanity and precision both have their place. John talking dirty can get *anyone* going, even a "married to his work" detective . . . and then Sherlock returns the favor. (He's not very good at it.)

You fit together; like she was made for you and you were made for her.

Dr John H. Watson is drunk. But then, it's his birthday, so no one's going to pull him up on it. Least of all Sherlock... Johnlock fluffy smutty one-shot. Rated M for a reason, a very good one!

Arthur orders Merlin to clean a neglected Excalibur, and they both discover an added benefit of their bond with the sword. MERTHUR, SLASH, PRETTY MUCH A PWP (but no Gwen bashing).

To Jason, Pythagoras was always more than just his healer. A slip of the...well, mouth, proves that Pythagoras had been thinking the same thing. Jagoras fluff.

Times are changing. In the wake of Uther's death, Merlin tries to cheer Arthur up, starting along a path that neither of them would have expected. One that both have dreamed of, but never dared to hope... Merthur. Happy ending.

As the trio crosses the desert for the second time, Jason does his best to help Pythagoras deal with the resurfacing of his childhood trauma – and due to a couple of long nocturnal conversations, he ends up learning a lot more about the young genius that he'd ever expected. (set after 1x08) [2st story of the SHoT series - gen, but hints of future slash]

Destiny kept pulling them apart, it will take the strength of a dragon to bring them together. Merlin / Mithian, steamy romance with some mental angst.

It wasn't until he hit the edge of the table that he realized Jason's intentions. "We're not doing it on the table!" he managed to gasp between kisses. "Mmm..." Jason's lips took a trip down his neck, trailing kisses as they went. "Why not?"

or 'How To Seduce An Oblivious Mathematician With An Arsenal Of Ridiculously Shitty Pick Up Lines'

The Rift monitor is acting up again, but Jack knows exactly who's causing the disturbance.

After losing the closest friends he'd ever had, the people he'd come to consider his own and the land that had become his home, Jason finds it very hard to adapt back to 21st century London.

Pythagoras had long been aware that he had a thing for sharp lines and angular forms. What he never expected was to become so utterly fascinated by a man he'd only known for two – albeit quite eventful – days. [1st story of the SHoT series]

Jason tilts his head. "Pythagoras, are you coming out to me?" Pythagoras frowns, points to a tree and looks around. "Are we not out already?" he asks, and Jason shakes his head with a laugh. "We're both out, yes." "I feel as though I've just missed a joke." Pythagoras barely catches Jason's mumble of, "Just one on me," and is left to ponder if that's a joke as well.

All Jaime wants is ONE night where Brienne agrees to get roaring drunk with him. That's what friends are for, isn't it? Canon compliant, Post-ADWD fluff.

One shot, first attempt at fan fic. Arthur confesses his emotions to Merlin, Merlin responds. Merthur, obviously. Rated 'M' because they end up naked together, but the scene is all about the Merthur romance feels. Enjoy!

Arthur gets spectacularly drunk during the feast celebrating his coronation, and says some things to Merlin that make Merlin doubt everything he thought he knew to be true.

The incontrovertible truth about Lancelot is that he loves Guinevere, loves her more than any person has ever loved another, cherishes her more than the air he breathes and the food he eats and the water he drinks. To Lancelot, Guinevere is more than the sun and moon, than anything in the world, than life itself. Lancelot loves Guinevere, but he kisses like he means it.

Sherlock's eyes flash with anger, the expression echoed in the doctor's face. They're close now, the air between them charged. There's a step between them neither is willing to take, not tonight. Perhaps not ever. — Sherlock can't get it in his head how much John truly worries about him. Johnlock. One shot. Rated M for heavy smut.

Sherlock has a problem. It's annoying and recurring, and John Watson is to blame with his inordinately protective deeds. Thank God for long coats. Johnlock. One shot. Rated M for some sexy times.

Mordred is in love with Merlin, and doesn't understand why Merlin won't return his feelings. Arthur notices him pining, and is determined not to let his own feelings get in the way of helping his youngest knight. Merdred with hints of Merthur.

A one-shot written for 'The Heart of Camelot' Valentine Challenge 2013 and set between episodes 1x04 and 1x05. After Gwen kissed Merlin, he suddenly realises how she feels about him and asks her out on a date. Book Cover by Wil1969

Merlin has a thing for one of Arthur's tunic. Arthur notices. Just a short little drabble.

Arthur's reaction to Merlin's, quite frankly, terrible wake up calls.

A curse has hit Camelot and now everyone is running around naked. Merlin must keep his magic safe and break the curse while dealing with nudist Gaius, Uther trying to cover up using his crown, and a very, very naked Arthur. All of it while nude himself.

Gwaine was an expert on kisses. He had become so used to kissing that the very act seemed so basic. It was what led to other more exciting things. He changed his mind when he met Merlin.

LEMON, slight pwp, Percival x Gwaine. Feelings come to light in a cramped tent. What else were they supposed to do when presented the opportunity? UPDATED.

When Merlin gets caught in a storm, the king and queen do everything in their power to get their friend warm again. However, it seems that they have an ulterior motive; a problem which requires a 'Pinch of Spice' to solve. An Arthur/Gwen/Merlin Threesome.

Of Merlin in purple and ass-flattering jeans and made up words and Arthur deluding himself into believing that it is, in fact, innocent to fantasize about your best friend and he's not at all gay. Except when he is. Merthur Slash oneshot

Merlin is constantly bullied by Arthur, he does his chores and picks up after the king, and yet he still never feels as though he is appreciated. Merlin has had enough of Arthur, and he's found a brand new way to shut him up...

Leon tried, as much as he could, to avoid patrolling with the other knight, but it wasn't something he could always avoid. Slash.

Mordred has decided that he rather likes meeting with Merlin in the abandoned corridor. It seems that poetry is quite the popular subject. Merdred Slash.

"You would do anything I asked of you, would you not?" Arthur/Leon

Merlin has a terrifying nightmare and it's up to Arthur to comfort him. One-shot Merlin/Arthur fluff

What really happened that night in Ealdor between Arthur and Gwen. My take on Guinevere comforting Arthur.

Arthur thinks Merlin has taken a lover and is overcome with jealousy. He follows Merlin one night, only to see him speak to Kilgharrah and his magic is revealed. Will Arthur's love allow him to see past it, or is it one betrayal too far? Slash.

Arthur can't take Gwaine anywhere! Canon era, set sometime after the end of season 3. All Arthur wants is a bed, but typically the folks in the inn know Gwaine... and they are not impressed to see him!

Morgana finds it easy to manipulate Agravaine. He want her love, she wants his undying loyalty. One Shot. PWP

My first Merlin fic. It's set after Gwen's coronation. Merlin finds comfort elsewhere.

Written for the prompt: Competitive Wii playing turns into competitive sex... Explicit sexual content and language - don't read if you're not old enough.

'Gwaine loves sex - he loves sex with a variety of people in a variety of ways...' But Gwaine isn't usually attracted to men who are bigger than he is. Percival, however, is the exception to the rule. PWP, Explicit adult content.

Elyan and Percival decide it's high time the King and his Manservant realized their feelings for each other. Along the way, they find each other. Set during/after season three. Slash.

Leon discovers that Gwaine has an interesting way of dealing with the aftermath of a fight. Leon/Gwaine

Merlin spends the night in Morgana's hovel. She decides to take advantage of that. 4x06. Merlin/Morgana.

This is some straight up PWP porn without plot because NO ONE would write Elyan/Percival and it needs to be done. So please read, love and maybe find some of your own inspiration. Slash and shameless porn ahead!

And then Arthur's hand landed heavy on his shoulder spinning him about and Merlin did the first thing that came to his mind. He shoved the key down the front of his trousers. Set after the wrestling on the floor sans trousers scene in 404.

Arthur sleeps with Merlin after he fires him in 'Valiant', but won't once he's rehired him. Merlin is not happy. Merlin/Arthur. SLASH. One-Shot

The steps they take to get there are hesitant, slow, careful. But somehow they get there all the same. "You're stuck with me," Gwaine promised.

Five times Gwaine interrupted Arthur and the one time he didn't or two . Slash in case you didn't figure that one out.

A Merlin/Lancelot take on episode 4x02 The Darkest Hour . Because, for me, that epsiode was completely filled with homoerotic subtext. This story will be continued until I've covered the entire episode. Slash.

Probably done before- Sherlock and John go to a gay bar- for a case! Sexy dancing, UST, and a happy ending, of course : R and R greatly appreciated!

Tequila, truth or dare, cross-dressing and lipstick lead to porn. My obsession with Merlin's lips continues : Mostly PWP, fluff and smut. Contains adult content.

Post S3, slash, P/M, Percival has always been a man of nature, most comfortable amongst trees instead of people.

Merlin innocently bumps into Arthur in a deserted corridor, the collision has unexpected and pleasurable consequences. Contains adult content and slash. Mostly PWP, just for fun! Merlin/Arthur.

Arthur's in love with Merlin. He thinks, hopes, maybe, possibly Merlin likes him too. Now he's just got to work on what comes next.

Arthur is nearly ready to take it to the next level. For rufflefeather, who requested Inexperienced!Arthur, first kiss, Merlin teaching him how to give a bj.

When Arthur strains a muscle, Merlin must tend to him.

Gwen had no idea how she had ended up in this situation. One minute she had just been standing there talking to Merlin and folding Arthur's clothes. The next moment, Merlin had pushed her against the cupboard and kissed her full on the mouth.

Silly one-shot story. Leon talks too much, Arthur can't hold his drink, Merlin's ears are assaulted, Gwaine learns more about being a knight and Lancelot gets stuck in the middle.

Merlin becomes Uther's servant for a day. One-shot. Warning: Definitely rated M, it's a Lemon, and it's kind of smutty. Uther/Merlin
