Summary: Sirius Black is very observant when it comes to others. Much less when it comes to himself. There's something that has been quietly developing in the recesses of his marauder-y brain. Something rather big and important.

Crazy Little Thing Called Love

Part I: Curiosity killed my innocence

Sirius was half-sitting, half-lying on Moony's bed, gazing lazily at the owner of the said bed as he was again going on about a book, something called "Crime and Punishment"...or was it "Pride and Prejudice"? Padfoot got them mixed up sometimes, which in return caused Remus face to take on that disappointed look that only he could successfully achieve and make Sirius feel guiltier than the one time he set a couple of house-elves on fire by accident (no long-lasting damage was done, thank god).

In his defence, Sirius couldn't really help it; was it his fault that he was way more captivated by Moony's quiet, honey-laced voice than whatever novel some sappy old bird had written centuries ago? His voice soothed the animagus. It made him instantly content with the world, as if nothing could ever trouble him, with the condition that he would never stop hearing Moony's soft droning about books he had never read and chocolate he'd never tasted.

Remus Lupin - a werewolf, a booksnogger extraordinaire, one of his mates. No, but those are not quite the right words now, are they? Because Remus was more than that, more than the chubby, lovable tagalong Peter and different from James in ways the boy couldn't quite describe.

Sirius averted his eyes. He realized he had been staring at Remus' mouth. It was a nice mouth. Very nice, in fact. Moony was quite attractive, if you asked him - what with his very nice mouth and very nice dimples and very nice eyes. Even his scars were very nice. Sirius had a sudden urge to trace the more subtle one that crossed the right side of his face, starting from his cheekbone, then travelling further across his cheek and fading out on his nose. Moony had a very nice nose as well. It was such a pity really, Sirius wished he had a nice nose. The current one, much to his displeasure, was too mean. He came from a long line of mean noses. Some of them even evil. This nose-talk was getting him down a bit so he zoned in on the werewolf's voice. Apparently, he failed at being discreet at this undoubtedly hard task and drew Remus' attention.

"What?" Moony glanced at the other boy unsurely.

"...Uh?" Either he was slowly turning into a troll or, well, turning into a troll.Sirius Black was a smooth talker, there was no excuse for this lack of coherence. Absolutely none. Bad Sirius! He mentally scolded himself.

"You sort of...-oh, never mind. As I was saying, Jane Austen is..."

Sweet Merlin, Moony was gorgeous. And he really wanted to touch that bloody beautiful scar. So, of course, he did.

As Moony had started talking about Mr. Darcy, the sandy-haired boy suddenly found slick, long fingers on and about his face. Brown eyes jumped out of their respective sockets and a smaller hand batted away the fairskinned fingers.

"...Padfoot, what in the name of Merlin are you doing?" Moony suddenly found the voice that was coming out of his mouth very unfamiliar.

Oh, he was used to full-body hugs that lasted more than some people would deem appropriate and next to no personal space. That was all a part of the usual contract when it came to being a friend of one Sirius Black, but this was quite new. Moony couldn't quite put his finger on what it was that differed so bloody much, except that he was blushing like a maiden on her wedding night.

"Moony. " Sirius announced as if he was about to make an official statement.

"Padfoot." Remus raised a skeptical, cut-the-nonsense-pads eyebrow.

"You are quite a swell bloke, Remus J. Lupin." He finished a tad lamely. The aforementioned Remus J. Lupin failed to notice the strange spark in his best mate's eyes. There was something else Sirius was really, really curious about. And now that he thought about it, had been for some time.

"Um, thanks?" Remus didn't really see where this was going, but he felt the blush spreading all the way down his neck. Sirius found this strangely adorable and made a mental note to compliment the boy more often. Then a pair of lips came to rest upon the corner of Moony's own and he lost the ability to do anything at all.

P.S. This is technically my first fic, so, you know, I'd really appreciate it.
