A/N: I know, I know, I should be writing Chaos Theory now. But I'm not. Because I don't FEEL like it, and I can't stand the latest chapter. Siriusly, it's terrible.

Okay, so this is a SLASH fic. YAY. Slash is my drug. :3

Canine Affinity

16 year old Remus Lupin rolled over in his bed. There were lots of confusing thoughts whirling in his head, and all he wanted to do was sleep. But he couldn't. Not while the other man was sleeping in the bed next to him. Remus had his curtains wide open, staring across to the bed beside his, half-hoping that the laughing face of Sirius Black would emerge, half thanking the gods that it hadn't. His mind was stuck on a continual replay of the events that had happened between them that evening.

000Flashback000

Remus had been sitting on Sirius' bed, doing his homework as usual. He had always loved being on Sirius' bed, perhaps it was the fact that they were both the only canine members of their pack, and so shared a special sort of affinity that neither of them had been able to dredge up for the other two. The closest either of them came was James' friendship with Sirius. Those two were two of a kind in every way, but at the end of the day, Sirius and Remus could both find consolation in that they weren't the only canine around. Also, there was the canine smell, the simple way it was nicer than that of a human, a rat, a cat, or even a stag. And they could both joke about the unmistakable urges to chase Professor McGonagall whenever she came too close.

Tonight, when Sirius came in, he sat down on his bed as usual, and Remus put away his homework, as usual, for their late night canine conversation. Sirius flopped down, resting his head on Remus' lap like he always did when he had had a bad day, and Remus began to fiddle with strands of his soft hair. There was nothing sexual in this, although it had been uncomfortable at first, Sirius and Remus had long since figured out that all their physical contact (and they needed twice as much as other people) was just platonic, and a side affect of being partly canine. The awkwardness had vanished, and they were as close as siblings who got along really, really well.

"I had an awful day, Remus." Sirius sighed, shifting heavily to rub his eyes. "And McGonagall seems to be testing me... she's always hanging around me, asking if anything's wrong. I wonder if she suspects us..."

"Probably not, Dumbledore's most likely just got teachers tailing you and James, and you were unlucky enough to be landed with her."

"Maybe, but I still think it's suspicious. I mean, she's practically brushing up against me every five minutes. Nightmare. Especially with Colleen and all."

Colleen was a girl Sirius was trying to break up with, although he was finding it difficult. Remus found it odd that he was trying to dump her, his only girlfriend of the moment. Maybe he had finally learned his lesson about treating women as objects, and was looking for true love, like James. Maybe he was just bored with everyone at Hogwarts already. "Have you broken up with the poor girl yet?" Remus asked, shaking himself from his thoughts.

Sirius nodded. "Managed to by pretending to McGonagall that I needed to go study with her."

"You know James will hate you for this." Remus said sternly.

"Why?" Sirius blinked, oblivious to Remus' exasperation.

"Don't you remember why you even got together with her? Colleen is Lily's best friend, and James got you a double date."

"Oh yeah." Sirius ran his hand through his hair, not caring that his hand wound up somewhere in the region of Remus' crotch. The werewolf didn't pay too much attention, though in retrospect, this was probably an important detail. "I've just been kinda out of it lately." Sirius sighed. "Trying to cut down the amount of things I have to worry about, y'know?"

Ah, so that was Sirius' mysterious reason for now being single. Remus had nodded slightly, smiling to himself. "I understand about not wanting so much stress, but it's alright to keep one girlfriend, most people manage that. God knows, without that harem of yours, your grades might actually improve!"

Sirius laughed. "Not bloody likely. I just need more pranking time, that's all. And I've been neglecting my friends lately too, you guys haven't seen nearly enough of me. Especially James, what with his hands full wooing Lily. Speaking of which, why don't you ever go out with girls, Remus? It's even more fun than you would think!"

Remus sighed. "You know why I can't, Sirius. If I let someone too close, they're bound to find out about me. And once they do, word will spread. You know the saying, telephone, telegraph..."

"Tell a girl." Sirius had concluded. "I know. But it wouldn't hurt to let one person into your life."

"I have. Three people, the three best friends in the world. That's more than enough, and I'm quite happy with you guys. I, unlike you, do not have a limitless libido." Remus smiled amusedly down at his canine companion, gently braiding and unbraiding the fine strands of thick hair.

"Yeah, but you don't even have magazines, Remus. I checked. How can someone have no libido at all?"

"Maybe I'm just not ready to let someone be that close to me yet. But the question is, are you ever going to actually get close to one of your girlfriends, or are you just going to use them like the condoms I know you keep under your pillow."

"I don't know." Sirius said, brushing aside the condom comment. "But I definitely want to give it a go."

"My my, Sirius Black, Stud of Gryffindor actually wants to give a serious relationship a go. Has the world come to an end?" Remus teased, letting go of Sirius' hair for the inevitable scuffle that would follow his statement. And follow it did, Sirius tackling Remus and them fighting playfully for several minutes. Only when they had called a truce and were lying, sweaty and panting, side by side on Sirius' bed did it occur to Remus that this was incredibly uncharacteristic. Had Sirius actually fallen in love with someone? Was it even worth their while to trust him? And who was it?

"So just who is she?" Remus panted, rolling onto his side to face Sirius.

"Well..." The animagus said cryptically. "A name beginning with RL... Beautiful blonde hair, and the most gorgeous eyes known to humanity." It looked like Sirius was leaning in, though Remus had been deep in thought at the time.

"Not Rebecca Lockheart?" He cried, when Sirius was mere inches away. "She's a bimbo, even dumber than her brother. And he's as dumb as they get."

"Ew!" Sirius yelped, jumping back. "No! She uses engorgio on her breasts every morning."

"Really? That must be why they're so disgustingly huge..." Remus laughed, then returned to the task at hand. "But she's the only girl in Gryffindor, Ravenclaw, or Hufflepuff who fits that description... You're not after a Slytherin are you?"

"No!" Sirius sounded genuinely disgusted, and that threw Remus off. He had assumed that it was a girl from school, but now, the possibilities were almost endless.

"What school does she go to then?"

"This school. This house. This year. See what I'm getting at?"

"No..."

Sirius sighed. "For someone who is supposedly so smart Remus, you sure are stupid." Sirius smiled affectionately, leaning in to gently kiss Remus on the lips.

After that, Remus had stumbled back to his own bed and collapsed in it, his entire body completely numbed at the thought that Sirius liked him. It was so uncomprehensible a thought, that someone could actually love Remus, that he had never even put any thought into it before. And now here he was, faced with something he had never had the faintest brush of experience with, and it was sleeping a few feet away. A part of him wanted to go and curl back up into Sirius' familiar bed, surrounded by the comforting scents, and just fall asleep, but the other half wanted to wait and see what Sirius did.

That half didn't have to wait long. Before ten minutes had passed, A black dog leaped through the scarlet curtains of it's bed, and sprang nimbly onto the opened four-poster of Remus Lupin. He looked at Remus hesitantly, then licked his hand. Usually, Sirius was ten times as affectionate and bouncy as a dog as he was as a human, and that simple, timid lick said more than Sirius had ever intended it to. Unable to help himself, Remus gathered the dog up in a tight hug, squeezing his best friend until he transformed back into a man.

"Remus...choking..." Sirius pointed out, and Remus blushed slightly, releasing him.

"Sorry." He smiled slightly.

"No problem. Just don't kill me. I really wouldn't appreciate it. Especially since I just told you how I... how I feel." He blushed, staring at his bare feet and the cuffs of his pawprint-dotted pyjama bottoms as though expecting to be reprimanded for his actions. Instead, Remus grabbed his chin, and dragged it up to face him.

"Look at me Sirius, you did nothing at all wrong. It'll just take me some time to get used to all of this, since I'm not sure how I feel about you yet. All I know is that I feel closer to you than I ever felt to anyone in my entire life, and I think I always will."

Sirius smiled, and embraced the smaller man. "That's all I ask." Smiling shyly, Remus returned the hug.

They just held each other for awhile, breathing in the scent, getting used to the feel of each other. But, of course, the famous libido of Sirius Black wouldn't be satisfied with that for long, and soon, he was gently trailing kisses along the side of Remus' neck. Remus tensed up, totally unused to this sort of feeling, but not exactly hating it. Slowly, awkwardly, he began caressing Sirius' bare chest. (The man preferred to sleep without a shirt on; he claimed that it made him feel free.) Sirius apparently liked that, because his kisses became more frequent, and Remus couldn't help a soft little moan escaping. Once it did though, he was mortified, and clamped up entirely, terrified that he had done the wrong thing. Sirius didn't seem to mind, though, and continued kissing, Remus gently relaxing with every brush of the lips. Before long he was returning the kisses and caresses, and didn't even notice anymore the at first awkward hand that had crept up his pyjama top. Sirius was lying atop Remus, though not so much as to crush him or make him feel that he couldn't get away. It was comfortable, and before long, absolutely every touch, every kiss, felt absolutely right, just like their absent little touches when hanging out on Sirius' bed. Remus didn't even notice when Sirius began removing his shirt, until it was off and he was getting cold, both of them being above the blankets.

"Now I see why you like this so much." Remus smiled between kisses.

"It's a million times better with you." Sirius replied softly, whispering gently in Remus' ear, tickling him and making the young werewolf giggle.

What neither of them saw were the shocked faces of their two best friends standing in the doorway.

A/N: I may continue this, I may not, but my author's muse says "WHY THE FUCK HAVE YOU STOPPED!" I was just PMSy and out of chocolate, and needed to be cheered up with some good Sirius-Remus lovin'. LEAVE ME CHOCOLATE AND REVIEWS, OR I'LL BITCHSLAP YOU AND CRY!
