Title: The Joy Of Breaking Rules

Summary: It was a game they played. In the common room, the Grand Hall, the classrooms, outside and in the library. Especially the library. And the best part of playing this game was breaking the rules. Marauder era. Sirius/Remus.

Rating: M for sex between men

Pairing: Sirius/Remus

Era: Marauders

Notes: In my school I used to have a bottom locker below someone (Fucking bottom lockers). The things and words that passed between us at the lockers inspired this fic. I love Remus and Sirius and I can't help but use everything in my life as inspiration to write about these two. Unfortunately Hogwarts doesn't have lockers (or fortunately, considering the likes of the Marauders and Fred and George) so the library will have to do. ;)

This fic is written differently to my other fics, it's not very humorous and it's slightly twisted but not in a dark or bad way. There's definitely no angst but it's not the way I usually portray these two. Meh, probably didn't work anyway :/

OOOOOOOOOOOOOOO

Chapter 1: This Game Has Rules

It was a game they played.

In the common room, the Grand Hall, the classrooms, outside and in the library. Especially the library. Imperceptible to anyone else but that was part of it, part of the game. They knew, they could feel it and see it sometimes, but no one else could. The knowledge that they were playing this game right under the noses of their fellow Marauders, peers and teachers who were none the wiser made it all the more exciting, more thrilling. And the blissfully unaware teachers and students couldn't have guessed if they did happen to notice a sly touch here and there; Remus the dedicated, sensible, studious Marauder and Sirius the womaniser, the bloke who was considered by himself and most of the female population as a sex god. No one suspected that beneath the friendly ribbing and unquestionable loyalty between them was a public sexual game being played.

The touches were usually light but unerringly sensual. Fingertips drifting down Remus' back as he stepped into the common room. Remus' leg rubbing up against Sirius' as they sat studying in the common room, his hand sliding up and in between Sirius' thighs before teasingly drifting back down as they sat unaware of Binns' lecture in History of Magic. And Sirius pressing his front up against Remus' back under the pretense that he was reaching over him to get powdered newt in Potions.

And then in the library. Their game had them frequenting the library so much that Madame Pince had actually started following Sirius in the library, suspicious of the suddenly studious troublemaker who had a notoriously short attention span. She needn't have worried; his interest wasn't in books and it certainly wasn't in studying. And whenever Sirius was in the library while Remus was, Remus wasn't interested in books or studying either. It was part of the game to pretend though.

Remus would stand, nose barely inches away from the spines of the books, brow furrowed as he carefully pursued a certain elusive volume among the endless, dusty shelves. Sirius would nonchalantly step behind him, one arm reaching up to pull out a book halfway from a higher shelf as he gazed at the blurb, while his other hand steadied himself against Remus' arm. Sirius' breath would be hot on the back of Remus' neck and Sirius would allow himself a small smile as he'd feel Remus shiver. Their bodies would drift closer together in what would appear to the onlooker a natural, fairly innocent way, their bodies pressing together suggestively but not to the point of obscenity. Remus would then turn slightly, as if seeking a book that might be further along the shelf. His hip would graze Sirius' groin and his breath ghost over the underside of Sirius arm. His mouth would twitch in an attempt not to smile as Sirius' hand would clench his arm convulsively.

And then, on a good day, when Remus was feeling particularly adventurous or felt like teasing Sirius a little more than usual, he would do something that almost forced Sirius to break their silent rule of no spoken acknowledgment of the game.

Unable to put his hand on a particularly desirable book, Remus would slide down in front of Sirius, sinking to his knees and making sure to rub his body against Sirius' front as he slid to the ground. Fumbling, Sirius would hastily pull out a random book and flip to an equally random page, trying desperately not to drop his act of being oblivious to whatever Remus did. This was always made more difficult when Remus decided that being on his knees with Sirius behind him wasn't enough torture. He would rest on his knees, legs curled under him and feet on either side of Sirius'. Then he would lean back, pressing his arse right up against Sirius' legs and his shoulder against his groin. Sirius would freeze, eyes staring at the same spot on the page, breath far too quick and shallow for a library but still not completely incriminating as to what he and Remus were doing. Sensing Sirius' slipping control, Remus would then slowly, tortuously, bend forward, inspecting a book closely as his arse rubbed teasingly over Sirius' slightly shaking legs. Sirius would slowly, inevitably let his gaze slip from the book to look down at Remus on his knees, legs slightly spread, bent over and arse pressing against him.

It was times like these where they each seriously considered quitting the game. But they'd never verbally acknowledged the game before or what it might mean. They were each too wary that they might not want to know whatever this might mean about themselves and each other. And what if the other reacted badly, if this really was just a game and nothing more to them? It was too daunting a possibility, too frightening a thought. So they continued to play the game. Remus would slowly stand up, brushing his shoulder against Sirius' groin as he did and flick Sirius an almost imperceptible smirk as he returned to his table where his bag and books were waiting. Sirius would remain there for a little longer to maintain the image of innocence, which was slightly tarnished by his flushed cheeks and quick breath. Then he too would return to the table he shared with Remus and they would attempt to focus on their work, trying to ignore how the other made their heart beat madly and their blood rush to unmentionable places.

Their game continued to be played up until a few weeks leading up to their NEWTS. The game was paused as they silently agreed that they needed to concentrate for their exams. Days were spent studying feverishly, Marauders huddled together as they helped each other and stressed together, Remus being the one who did most of the stressing. After their exams were over, they, as well as the rest of their year, breathed a sigh of relief. There were parties in celebration, organized mainly by an exuberant James and Sirius, but even the likes of Remus and Lily consented to let off a bit of steam and go a little wild. They were teenagers after all.

But despite it all, the game remained pause. There was no viable reason to return to the library and stand among the shelves, looking for difficult and boring books for long periods of time. There were too many people lazing about in the heat of the approaching summer for their game to go unnoticed. And they both felt a strange dread creep over them as they realized their days at Hogwarts were numbered and that the game would have to end.

That was why, one day, nearing the commencement of the summer holidays, Remus Lupin was found by none other than Sirius Black, staring in glum reminiscence at a row of books among the shelves of the library.

OOOOOOOOOOOOOOOOOOO

Bleh.

That is all.
