Dear lord! Yes, I am aware that I haven't written any Siri-Remy-goodness for ages, and I'm sorry people! To my defence I'll say that every time I tried to circle my plot bunnies around them, Sirius would humpfh and close the curtain around his - well, technically Remus' - bed, proceeding to go at it with his wolf not appreciating my presence there at all... However, whenever he thinks he's done something brilliant, Sirius, being Sirius, is always eager to share it with everyone who cares. (Not to mention a whole lot of those who really don't!)

Hence, this story managed to slip out of my head and through the keyboard. :] Hope you're not too pissed with me, people (if any of you remeber me at all, that is), and I hope you enjoy it at least a split of what I did writing it!

Oh, and the only thing that's mine is our favourite canines' inventiveness (is that even a word?)... But that's something, right?

Right, and obviously, this is Sirius/Remus slash (and though I tend to keep it mild most of the time, I feel obliged to notify those of you who don't like this and haven't realized it yet). Just saying, so don't say you haven't been warned, because I don't care much for liars.

You've been marked!

Sirius' graffiti skills

"Sirius!"

The exasperated cry from one Remus Lupin, who had by far earned his Outstanding in Charms and knew curses that would even have a slytherin raise an eyebrow – not that he had ever cast them at anyone –, was sure to make anyone in their right mind shiver like an aspen leaf and hurry out of the sixth-year's sight.

Adding the fact that he was at least twice as strong and fast as he looked – and that once a month he was capable of tearing a fully grown human being apart with such ease that it might as well have been a brittle piece of paper – to the list did nothing to make him less terrifying.

The few people who knew him well – and were aware that it was full moon in less than a week now – should most definitely find the teenage wizard utterly intimidating right now. In fact, Peter Pettigrew squealed and hurried out of the dormitory while still in his pyjamas looking for cover upon hearing Remus Lupin this annoyed.

James Potter, however, wanted to prove his gryffindor bravery and would not – I repeat: not! – put his stag-y little stump of a tail behind his legs and run, no matter the threat. Instead he hurriedly pushed the supposed best friend of his towards the source of the sound that had interrupted the peace in the gryffindor boys' dorm this morning to make sure that he didn't come between Remus and the object of his annoyance. Yes, very brave indeed, James!

"Sirius Orion Black, come here this instant!" Remus bellowed from inside the bathroom.

Said Mr Black must be utterly insane – no surprise there – for he did not find this the tiniest bit scary at all. Instead he took on a mischievous smile as he calmly entered the bathroom to find a half-naked – sweet joy! –, light-brown-haired prefect in front of the mirror over the wash-basin on the wall.

"You wanted me here, Moonshine?" he said in his most charming and polite, completely breath-taking and heart-stopping voice ever.

"Don't you Moonshine me, you mutt!" Remus warned, for once unimpressed by Sirius' charming ways. "Look what you've done to my neck! It's abused!"

Sirius ignored the fact that Remus hadn't melted into a puddle on the floor yet, and so he put on his most dazzling grin ever and tried again.

"I can't recall you protesting much about it yesterday evening, dear", he said while wrapping his arms around the werewolf's bare torso from behind, softly caressing his lover's skin with his lips.

"But it's bloody glowing!" Remus declared, even though Sirius triumphantly felt the boy's body giving in to his touches. "It won't go away magically."

"No?" the black-haired teen wondered lazily, gently nipping at Remus' neck with his teeth despite the conversation they were currently having. "Let me try", he continued and drew his wand.

Directing it at Remus' neck while tugging at him to turn towards him and away from the mirror, he mumbled a couple of words so quietly that even Remus with his werewolf hearing failed to decipher what was being said. The lycanthrope felt a strange sensation at his neck, though, and was curious to see what had happened.

"It tickles", he informed the black-haired Casanova and was about to turn back towards the mirror when Sirius' hands prevented him and moved his head up a bit towards his own, only to press his lips against the brunette's in a quite mind-blowing kiss, if he may say so himself.

"Sorry, didn't work", he said as soon as he'd let go of the other boy's mouth, sounding anything other than sorry.

"Huh?" Remus was surprised by Sirius' nonchalant tone of voice, and in the back of his mind he suspected something wasn't entirely right – well, except for the fact that it seemed that he would have to go to Transfiguration with an extremely evident love-bite on his neck! – which made him all the more anxious to check his neck, but that would simply not do to Sirius.

"It seems you will have to keep it for a while, love", he murmured against Remus' collarbone, then proceeding to place butterfly kisses everywhere he could reach.

"You don't seem particularly unhappy about this", the brunette pointed out, though he was now quite out of breath and couldn't remember why he'd thought anything to be wrong to begin with.

"I'm not", Sirius unashamedly admitted with a tricky smile. "It suits you."

Half an hour later both boys was rather flushed as they ran through the hallways on their way to McGonagall's classroom. Not that the fact that they were running had particularly much to do with that…

x-x-x

"Remus, what's that on your neck?" Lily Evans asked with a frown, her voice low as to not evoke the anger of Madam Pince.

The boy in question blushed violently at this question and hurried to straighten his collar, completely ignoring the book he'd stupidly been trying to reach on the highest shelf – without magic and definitely without consideration – which had lead to him exposing his neck more than usual.

"Um…" he started, feverishly trying to come up with a good response to that.

Lily preceded him, though. "I mean except for the love-bite, which by the way is very evident even from a couple of metres of distance when your collar fails to cover it up", she clarified with a somewhat smug smile, startling Remus for a moment.

"And you're telling me this now?" Remus exclaimed, eying her accusingly. "After I've been through an entire day of various classes?"

"Well, I figured you already knew and that pointing it out in the morning would only make your day more unbearable", she said in her defence, though still smiling ever-so-slightly.

Remus sighed. "Oh, well, I guess I was hoping for it merely to be me who thought it to be way more evi- Wait, what?" He abruptly interrupted himself when realizing what Lily had said so far. "What do you mean, 'except for the love-bite'?"

"Why, the text, of course", the gryffindor lioness stated simply. "From a distance I merely thought it to be dirt or some trick of the lights in the classroom, but then I noticed how other people were giving you amused glances and now I could actually make out a few words of…"

"Are you telling me that there's text on my neck that I did not know about?" Remus interrupted with a whisper so sharp that it almost turned into a hiss, a sinister suspicion growing within him.

"Again, I assumed you knew", Lily said with a shrug, but she couldn't keep the curiosity out of her eyes and soon she tugged at her friend's collar to be able to see the text clearer.

"'Sirius was here…'" she read, but was interrupted before she could finish.

"What?" Oh, there was the real hiss, alright.

"'… And intends to return'", she continued, now having to put up quite a lot of effort as to suppress a giggle.

"Oh no, he didn't…" Remus growled under his breath, but Lily shut him up by claiming there to be more yet.

"'Offender who reads this'", she continued: "GET THE FUCK AWAY FROM MY MOONY'S NECK!'"

"Miss Evans!" came the reprimanding voice of the librarian immediately from around the corner. "Keep your voice down and mind your language!"

"S-sorry, Madam Pince", she blurted out in a lower voice, fighting to speak coherently despite the fact that she was now bubbling with laughter and found it very hard to control herself.

Remus, on the other hand, was clearly more annoyed than amused, even if he really wasn't so very surprised that Sirius had done something like this – it was Sirius, after all, and over the years Remus had learned to expect the unexpected from that boy – and he wasn't quite as annoyed as he seemed at the moment, knowing fully well that it was impossible to be mad at Sirius, especially for him.

Nevertheless, he sure meant what he said, even if he made sure to keep his voice down as to not get kicked out of the library.

"He's so gonna get it tonight!"

Okay, so whatcha guys think? Anyone out there curious on how Remus will carry on with his payback? Anyone curious enough to want a second chapter? I'm working on it right now, so if that's the case with any of you, make sure to review! :D

Also, you could of course review simply telling me that you liked/didn't like it! *nods my head encouragingly* Constructive criticism is my best pal! *wink, wink*
