The club was more crowded than Sirius had anticipated which was both a good and bad thing. Good because he didn't stand out as he people-watched instead of dancing or trying to pull, and not so good because there was little chance of seeing someone acting suspiciously with all the men milling around.

And the killer could be at any number of Muggle gay clubs or pubs picking up his latest victim.

Despite Moody's hedging earlier today, Sirius was positive that the latest victim, Ben Holland, had, in fact, visited the nightclub the night of his death. His gut told him he was right; that the killer – he wasn't ready to declare a werewolf the culprit just yet – was bold and arrogant and territorial, and would keep killing in the same area until his prey dried up or until whatever game he was playing was no longer fun. Only then would the murders stop. Sirius was certain of it. He could feel it in his bones.

So, they had a wizard – possibly an unregistered werewolf – who had possibly infiltrated the Muggle London club scene and was taking out their gay men. Was this Muggle hatred from a homosexual or bisexual wizard, or did the prejudice run deeper? Were these attacks aimed specifically at gay men for a reason?

Sirius took a sip of his beer and let his mind wander as his eyes searched the club for anything suspicious. As a gay wizard, he was very aware of the attitude towards homosexuality amongst the elders of the wizarding world. It wasn't so much that the act was considered abhorrent or wrong – any boy who'd been to boarding school had had at least one sexual experience with another boy; it was like a rite of passage. It was more concern that an increasingly dwindling magical population would be hurt even further by encouraging openness in regards to sexuality.

In the past, gay wizards had taken a wife, lesbians, a husband, and they popped out an heir or two. No one questioned what happened behind closed doors, or what arrangements were made within a marriage as long as the couple contributed to the next generation. But now, wizards and witches were choosing to forgo the pretense and be open and honest about their sexuality, and concerns were being raised about what effect it might have on the future of their community.

That's why Sirius chose Muggle clubs: much less judgment and pressure to 'do the right thing'.

Sirius sighed. His family had threatened to disown him when he came out. He'd taken the decision away from them, though, and walked away himself, cutting off all ties. He couldn't say that he missed them all that much – James, Lily, and Peter were all the family he needed – but sometimes he watched James with Harry and a little part of him wondered what kind of father he might have been,what kind of life he might have had if he'd followed tradition instead of his heart.

He shook the shadow of melancholy off, telling himself to stop being so ridiculous. He was happy being out, and the fact he liked to sleep with men didn't mean he couldn't have a family one day, although the lack of a steady partner might be a problem. He didn't have any desire to be a single father.

And if I keep doing this – shagging strangers in clubs – I'm not likely to find a decent bloke either.

As if he'd read Sirius' mind, Remus appeared in the darkened doorway, hands shoved into the pockets of his leather jacket as he scanned the crowded room. Sirius waited until Remus looked his way then raised his arm and waved. Remus' face morphed into a combination of relief and reluctance when he saw the motion, and Sirius watched him move slowly through the crowd, as if his body still wasn't convinced about this course of action.

Sirius lifted his beer to his mouth again, swallowing down the last of the brew. He had never met one of his anonymous fucks after they'd both zipped up and done the awkward thank yous. Well, not that he was aware of, anyway. That night with Remus, though...

Sirius shifted in his seat as his cock stirred. It had been pretty bloody amazing by night club shag standards. They'd moved together like they'd been doing it forever, their bodies responding to every caress as if they'd spent years learning exactly where and how to touch each other. There was an undeniable chemistry between them and, although asking Remus out today had been an impulsive decision, Sirius had found himself looking forward to getting to know the other man better.

'Hey,' Remus said once he was close enough for Sirius to hear, a tentative smile on his face.

Sirius smiled brightly back at him, pleased when the uncertainty left Remus' face and his smile became more sure. 'Can I get you a drink?' he asked, and Remus nodded.

'Whatever you're having.'

Sirius got served quickly and returned to Remus, handing him a pint of beer before sitting down beside him. His knee pressed against Remus' and heat traveled from that point of contact to pool in Sirius' groin. He saw Remus hesitate as he lifted the beer to his lips then he finished the journey, leaving his leg where it was while he sipped at the drink. Sirius smirked, bringing the glass to his mouth to hide it.

'Busy for this time of night,' Remus noted, Sirius leaning close to hear him over the thumping music. 'I thought it would be quieter.'

'So did I,' Sirius admitted then he bumped Remus' shoulder with his own. 'I'm glad you came.'

A slow smile spread across Remus' face and he stared out at the dance floor as he quipped, 'Haven't yet.'

Sirius laughed, surprised but delighted at Remus' mischievousness. 'There's plenty of time,' he replied, a promissory note in his voice.

Remus chuckled, the sound making Sirius shiver. He pulled himself together, taking a fortifying mouthful of his drink before he said, buoyantly, 'So, tell me about yourself, Remus Lupin. What on earth inspired you to try and teach those Weasley boys anything?'

'They're a handful,' Remus admitted with a laugh. He moved so he was facing Sirius, their legs losing contact. 'I was going through a tough time – my parents died with a lot of debt, I lost my job because of all the time off I took to organise the funerals – and Molly and Arthur took me in, gave me a place to live and a bit of purpose. I owe them a lot.'

'They're good people,' Sirius agreed, thumb rubbing along the rim of his glass. 'How's Harry going?'

Remus grinned. 'He's fantastic,' he said enthusiastically. 'He's so inquisitive, and already showing signs of being really talented.'

'He's a brilliant kid,' Sirius said proudly.

'How do you know Lily and her husband?' Remus asked, cocking his head.

'We all went to school together. James is my best mate.' Sirius shifted to a more comfortable position, his spread legs now either side of Remus', knees bumping gently against each other. 'I'm the one who listened to his constant moaning about Lily not giving him the time of day.'

'She wasn't interested?' Remus asked, his eyes dropping momentarily to their legs before rising to meet Sirius' gaze. He smiled then took another sip of beer. 'How'd they end up together then?'

Pleased by Remus' acceptance of their proximity, he pushed a little harder, rubbing his leg slightly against the other man's as he answered. 'Lily finally gave into his charms...'

Remus looked sceptical and Sirius laughed. 'Yeah, okay. James pulled his head in and stopped acting like an arrogant prat. She gave him one chance to impress her and...' He shrugged. 'I guess he succeeded.'

'And what about you?' Remus asked, one hand playing with the cardboard coaster his drink rested on, the other coming to rest on his thigh – a scant inch from Sirius' knee. 'No significant other wondering where you are, or under the impression that you're working late?'

Sirius shook his head. 'I don't cheat,' Sirius told him soberly. 'I'm honest about who I am, and what I'm looking for.'

Remus looked at him thoughtfully. 'And what are you looking for, Sirius Black?'

Sirius sucked his bottom lip into his mouth, his own hand falling to his knee. 'Someone who understands the game,' he murmured, leaning in so Remus could hear him. As he moved, he shifted his hand, rubbing his forefinger lightly over Remus' knuckles. 'Someone who can give me what I want without there being strings attached, and someone who wants the same for themselves.'

'And what exactly do you want?'

Remus was so close now that Sirius could almost taste each breath, could almost feel the warmth of his body. 'Right now?' Sirius asked. 'You.'

Remus' mouth quirked up at the corners then, just as Sirius was going in for a kiss, Remus moved back. Sirius watched, bemused, as the other man nonchalantly lifted his drink to his mouth then placed it very carefully back on the coaster. He glanced at Sirius out of the corner of his eye and smirked. 'You're assuming that I want the same,' Remus retorted, a challenge in his eyes as he turned to look at Sirius. 'What makes you think I'm interested in seconds?'

Sirius licked his lips, his gaze falling to Remus' mouth. 'You're here. And I do owe you a reciprocal blow job.' Sirius' voice low and slightly gravelly with need. 'I always pay my debts.'

Remus exhaled, the tickling breath moist against Sirius' skin as he dipped his head, mouth brushing Sirius' jaw as he said hoarsely, 'You know, I did say I wanted an early night...'

Sirius shuddered as Remus nipped lightly at his jaw then stood abruptly, hand gripping Remus'. 'My place?' he suggested roughly, and Remus blinked in surprise.

'Not here?' he asked, looking towards the shadowy corridor where their last assignation had taken place.

'Not for what I've got in mind,' Sirius growled, and was pleased and so fucking turned on to see Remus' expression become predatory.

'Oh, yeah,' he agreed, tightening his fingers around Sirius'.

Sirius grinned and headed for the door, almost knocking over a few gyrating bodies as he dragged Remus along in his wake. Outside, the cool night air hit them like a punch after the accumulated body heat of the club, and cleared Sirius' head of the lusty haze that had been clouding it. He stopped suddenly at the mouth of the side alley, Remus slamming into his back.

The murder. Damn, he was supposed to be working...

'Shit, give a bloke some warning,' Remus complained then he caught sight of Sirius' conflicted face. 'What's wrong?' He frowned. 'Look, if you've changed your mind, I will call you many colourful names – cock tease being first on my list – but I'll live...'

'No, I just...' Sirius bit down hard on his lip. He was here unofficially. Why shouldn't he have some fun before the hard slog of a murder case began properly?

'Sirius?'

Sirius looked at Remus, at those blue eyes darkened with desire, that mouth so ready for Sirius' lips, and made his decision. He launched himself forward, kissing Remus with a voracity that obviously startled the other man, but, with barely a second's pause, Remus was kissing back just as fiercely. They stumbled back into the brick wall of the club, Remus' fists curling into the soft leather of Sirius' jacket as he ground his hips into Sirius' thigh. Sirius groaned into Remus' mouth, rocking his own hips forward to crash into the other man's.

'Gods,' hissed Remus, biting down hard on Sirius' lip. 'Get us out of here before I fuck you into this wall.'

Sirius' knees wobbled at the low growling tenor of Remus' voice, and he grabbed hold of the man's shoulders. He pushed Remus back a little, needing space to concentrate on his flat so he didn't splinch off something he was very much hoping to use in just a few minutes. He checked the immediate vicinity for witnesses then closed his eyes, tightened his grip on Remus' shoulders, and turned in a slow circle.

The two men appeared in a brightly lit hallway, Remus wincing a little at the sudden shift from dark to light before he yanked Sirius close and gave him a searing kiss. Sirius slid an arm around Remus' neck – partly to keep him near, partly to hold himself up on his still-shaking legs. He fumbled with his sleeve holster as he tried to extract his wand, unable to concentrate long enough to do the spells wandlessly. With a quick swish, the door flew open, and Sirius pulled Remus into his flat, kicking the door shut behind them.

Hands shoved impatiently at their clothing, and they left a trail of shoes and belts and shirts all the way up the hall. They crashed through the doorway of the bedroom and tumbled onto the bed, bare chests rubbing tantalisingly together as they kissed hungrily, messily. Sirius sank one hand into Remus' thick brown hair then dragged the other down Remus' spine to his arse, cupping the soft flesh and squeezing. Remus groaned, the noise reverberating through Sirius' body, then he tore his lips away.

Sirius made a noise of protest, raising his head off the mattress to try and capture that kiss-swollen mouth once more, but Remus latched onto the curve of Sirius' neck, sucking a bruise into the skin under his ear. His hands slipped between their bodies, busying themselves with Sirius' belt. Sirius arched up into the touch as Remus' fingers grazed his denim-covered erection then shoved the other man off him. He pushed Remus onto his back, grinning down at the surprised man for a second before straddling his thighs. His hands made short work of Remus' fly, tugging the jeans and briefs down far enough to release Remus' imprisoned cock. His mouth watered a little, watching the thick, hard flesh slap against Remus' belly before he bent to take the throbbing cock deep into his mouth.

Remus swore effusively. His hands caged Sirius' head, fingers threading into his hair as he rocked up into Sirius' mouth. Sirius held him down, fingers splayed wide across Remus' hips as he greedily tried to maintain contact with as much skin as possible. He swallowed Remus' cock down then drew back, the tip of his tongue flicking feather-light along the raised ridge of the crown.

Remus gasped then swatted at Sirius' head, pushing him away with a strangled, 'Sirius, wait!'

Sirius grinned up at him and Remus glared as he struggled to slide out of his pants. Sirius lifted himself off Remus' thighs to help strip them from his legs, nipping at his inner thigh and chortling at Remus' breathless cursing. Remus kicked the jeans away then gave Sirius a sudden shove. Sirius fell back onto the bed and, with a laugh at his surprised expression, Remus yanked down Sirius' tight jeans, muttering, 'Fucking sure of yourself going commando,' before he tugged the jeans free of Sirius' foot and roughly pushed his legs apart.

'You smell so good,' Remus moaned, dropping down to bury his face in the tight curls at Sirius' groin and nuzzling the base of his cock with his nose. 'I want to fucking eat you.'

Sirius chuckled then groaned when Remus licked a broad stripe along the fat vein on the underside of his cock before sucking two of his own fingers into his mouth, making lewd noises as he wet them.

'You think you're going to fuck me?' Sirius gasped out, feeling he should put up some kind of fight for position even as his arse clenched eagerly in anticipation.

Remus smirked and rubbed his spit-slicked fingers teasingly over Sirius' hole. 'Are you really going to say no to me now? he asked huskily, dipping a finger just inside Sirius' entrance, making Sirius' breath hitch audibly.

'Just get on with it,' Sirius demanded, bucking up in an attempt to force those probing fingers deeper.

Remus lowered his head, taking Sirius' cock into his mouth just as he thrust those fingers inside his arse, right up to the knuckle. Sirius cried out at the pain-tinged pleasure, his hips snapping up as Remus sucked hard, his fingers brushing over Sirius' prostate with every bob of his head. Remus' greedy mouth worked Sirius' cock like he'd been doing it forever, quickly bringing him so close to the edge that Sirius had to push him away far sooner than he wanted to.

Remus raised his head, a carnal, almost animalistic expression sharpening the angles of his face and exciting Sirius so badly that he had to grip the base of his cock firmly to stave off the threat of orgasm. 'Turn over,' Remus ordered, even as his large hands were encouraging Sirius onto his stomach.

Remus gripped Sirius' hips and tugged until Sirius was on his knees, his face pressed into the mattress. Sirius canted his hips, thrusting them into the air, then he let out a high-pitched whimper when he felt warm breath against his buttock. 'Remus,' he breathed reverently, fingers fisting in the bed sheets as he felt the first touch of Remus' tongue against his stretched pucker. 'Merlin, Remus...'

'Taste so good,' Remus whispered, mouth moving against Sirius' buttock before he bit down.

Sirius yelped, jolting from the sudden sting. Remus bathed the abused flesh with his tongue then went back to lapping at Sirius' hole, licking him open, stretching him, with fingers and tongue. Sirius was almost sobbing at the rush of sensation by the time Remus pulled back. He hissed through his teeth as cold lube slicked his hole, the feeling juxtaposed almost immediately by the burn of Remus' cock as it impaled him in one unrelenting push.

Sirius cried out, the intense stretch almost too much for him to bear. Remus seemed to sense this, pausing for a long moment until Sirius's body stopped clenching around his cock then he plastered himself over Sirius' back and whispered, 'Yeah?' into the hair at his nape.

Sirius murmured, 'Yeah,' back, feeling a hot, open-mouthed kiss being pressed against the jut of his first vertebrae before Remus withdrew from him completely then slammed back inside. Sirius moaned gutturally, pushing back, trying to get moremoremore of Remus inside him. Remus seemed to understand what he wanted and hooked his forearms under Sirius' shoulders, pulling him up and back until Sirius' back was pressed against the wall of Remus' chest.

'Oh, Gods, yes!' Sirius cried, reaching back to wrap his arms around Remus' body.

'Fuck yourself on me,' Remus whispered, nipping at Sirius' earlobe. He held Sirius tight to his chest with one arm, sliding the other between Sirius' spread thighs to roll each testicle between his thumb and forefinger. He nibbled a trail along the tense cord of Sirius' neck, making them both groan, then Sirius braced himself with a hand on the headboard and moved; rising and falling, letting Remus' cock slide almost entirely out of him before he sank back down and let it fill him.

They moved sinuously together, Remus breathing hard in Sirius' ear as Sirius panted, short and sharp. When Remus' hand shifted from Sirius' balls to wrap around his cock, Sirius keened and rocked forward into his fist. The slap of sweaty flesh and their ragged breathing was punctuated by long, drawn out moans as they drove each other closer and closer to the point of no return and then suddenly, with a clever twist of Remus' wrist, Sirius was right there, falling over the edge with a breathless recitation of Remus' name.

Remus grunted then growled out, 'Sirius!', one last powerful thrust bringing about his own end. Sirius, his satiated body boneless in repletion, slumped back against Remus, letting the other man take all his weight as he rode out his orgasm. He felt Remus finally relax behind him, his breath hot on his neck as he trembled with the aftershocks. They fell forward, Remus' cock dislodged in the process, and Sirius landed face first on the mattress, feeling the bed depress next him as Remus collapsed.

There was silence while they caught their breath and feeling returned to Sirius' extremities. As soon as he was capable of movement, Sirius turned his head to look at Remus, smiling when he saw the other man staring wide-eyed back at him.

'We're fucking fantastic at this,' Sirius said enthusiastically, and Remus laughed, the carefree sound making Sirius' grin widen.

'There isn't a word for how good we are at this,' Remus corrected, reaching out to flick a lock of dark hair off Sirius' face, the backs of his fingers brushing over Sirius' cheekbone.

Sirius made a noise of agreement, his eyes closing at the touch. After a slight hesitation, those long fingers combed gently through Sirius' hair. 'Mm, 's nice,' Sirius murmured, reaching out to touch Remus' wrist, skimming his fingers along the other man's arm. His fingers touched smoother, tougher flesh and his eyes opened.

'You've got scars,' Sirius mumbled sleepily, tracing the line of one silvery mark.

'Accident,' Remus said shortly then he rolled closer and kissed Sirius so gently it made him ache. 'I should go.'

'No,' Sirius objected, tightening his grasp on Remus' arm. 'Stay. I still haven't had a chance to pay you back properly for the other night.' He let go of Remus' bicep and ran his hand through his hair. 'I promise if you give me an hour's rest, I'll be ready for more.'

Remus raised an eyebrow. 'An hour?'

'Hey, it's been a long day and we were really good and I was doing most of the work there in the end.'

Remus chuckled and leaned in for another kiss, this one just as sweet as the last, but this time, it lingered. Their lips slid together languidly as their tongues explored, taking the time to discover all the nuances of each other's mouths. Sirius pulled Remus in closer, their bodies flush, and slipped a leg between his thighs. Remus moaned in appreciation, rolling them so he was lying across Sirius' chest.

The kiss deepened, and Remus stroked his hand over Sirius' hip, spreading it over his flank possessively. Sirius surprised himself by pressing closer, encouraging Remus to hold him nearer. He'd never really liked the after part of sex, but this... this was nice. Really nice.

Remus kissed the corner of Sirius' mouth then sucked softly at the skin over his pulse point. Sirius let his head fall back, tangling his fingers in the hair at Remus' nape. He felt the rumble of Remus' laughter thrumming over his hypersensitive skin and murmured, 'What?'

'You underestimated your recovery time,' Remus answered, rolling his hips against the evidence of Sirius' growing arousal.

Remus' own thickening length pressed into Sirius' thigh, slipping between his legs and nudging his balls. Sirius smiled. 'I'm not the only one with a short refractory period.'

Remus lifted his head and grinned at him. 'I'm insatiable, baby. Didn't I mention that?'

Sirius laughed and pulled Remus back down, kissing him soundly. 'Prove it.'
