He froze at the doorway.

The record player was blasting, and Sirius was spinning and swaying past the empty four-posters. It was Queen, of course, and Sirius was channelling Freddie Mercury, delicate curls of hair clustered on his bony sternum, with his boxers pulled up past his hips. A smile crept its way across Remus' cheeks to his mouth at the sight of Sirius Black's arse cheeks swinging below the edge of his pants as he waltzed around the room, feet slapping the floorboards.

"Ooooo, love," Sirius sung from his bare chest, throwing his arms out like a drunken orator, his face full and guileless and joyful, "Oooooo, love-er-boy – what you doin' tonight, hey, boooy?"

But of course, Remus though, he's a good old fashioned lover boy Saturday mornings. He couldn't bring himself to move. As long as he stayed quiet as a church mouse, he reasoned, as long as he didn't interrupt, it would be quite alright to bask in the unselfconscious glory of Sirius performing for himself alone.

"Oooo-ooo, can you feel my love heat? Come on and sit on my hoooot-seat of love…" Sirius continued, dragging his hands up his ribs and chest to his neck, hard enough his nails briefly left pale lines along his sides.

Remus coughed politely.

"So this is what you do when everyone else is at Quidditch practice."

Sirius spun on a heel to appraise Remus at the door, while Freddie continued to enunciate yearning. "This, or wank elaborately," agreed Sirius, over the music.

"You don't want to know," elaborated Sirius at Remus' raised eyebrow.

"Hmm, I'm sure you're right," demurred Remus in his most dispassionate tones. "I'm just dropping stuff off – don't mind me."

He walked past Sirius to his bed, dropping his bag unceremoniously on the floor and shedding his cloak. The morning was warming fast. Sirius collected himself and retreated to the far corner to fiddle with the record player. Synth chords brought in another Queen song.

"Ooooo, you make me live," serenaded Freddie and Sirius in triumphant tandem. Remus turned, half-out of his jumper, to watch Sirius pad his way towards him with the doodling bass-line. His face was a beautiful mock of sincerity, mouth gentle, eyebrows a little drawn, hands open, as he sung about long times and true feelings and wanting this girl to know he really loves her. Remus' heart twisted some, but it was a fresh summer morning and his chest cavity was plenty roomy.

Sirius had come close, all jubilant knees and ankles. He reached out and tugged Remus' jumper where it was rucked around his armpits and helped him out of it, singing and stepping all the while, "Aww, you're my best friend." He took Remus' hands and met his eyes and sang, "In rain or shine, you've stood by me, boy…" and the room changed, as if the atmospheric pressure dropped, or the angles of the wall shifted.

Sirius stopped singing, and dropped Remus' hands. Freddie continued, of course, voice ablaze with gratitude and wonder at the miracle of friendship, as the synth and kit neatly knocked out four and the sun streamed in the windows.

Remus cleared his throat and dropped his eyes to the floor, a little to the left of Sirius' bare feet.

"Yeah, yeah, I know, I'm a fucking queer," said Sirius, and threw himself onto Remus' bed. "I just love this shit so much. I had no idea. No idea at all. I – I just – you know – I feel – so good! Sometimes. It's just – urghhhhh," he gave up and flopped back onto the bed, making the mattress creak.

Remus chuckled, and perched by Sirius on the bedframe.

"It's, uh going to be a nice day. A really good one. It's already pretty hot out there."

Sirius groaned and covered his face with a pillow, muttering unintelligibly into it.

"What's that, Black?" asked Remus.

Sirius chucked the pillow away and laid his palm on his navel, drawing a deep breath into his belly, under his hand.

"I want you to touch me," he muttered.

Remus shot a wary look at him. "You should know by now I'm not wrestling you."

"Not that." Sirius' expression grew more guarded.

Remus stood abruptly. "I should go," he said. "Library."

Sirius seemed to have his eyes fixed on something on the ceiling. "It's going to be a beautiful day. Don't waste it in the bloody library. Remus, I – I want you. I can't stop thinking about – about your hands, your mouth…" He groaned, and covered his face with his hands. "I can't fucking look at you these days, I want you so much. I'm so scared. You were gonna figure it out eventually, even though you're so dense about these things. Best you hear it from the centaur's mouth."

"Awww," Freddie half-crooned, half-groaned, "Awww, you're my best friend."

Breezes danced in the room, sharp with the morning, playing across hard-bitten surfaces of wood and stone turned dappled and buttery in the golden light. The day exhaled across Remus' scalp and nuzzled into the hollow at the base of his neck. Sirius' figure was a tensed line bisecting the bed, and Remus watched the air caress him, plucking tenderly at the hems of his boxers and the hairs on his forearms shielding his face as his chest moved shallowly up and down. Remus could see gooseflesh ebb across Sirius' sides. Minute follicles pricked alert as the sun's warm tongues laved his flanks and thighs and then slowly, shyly relaxed, downy curls flattening against nerve-thick skin. His body was like a pool of water, ripples and reflections of curious creatures lapping at mossy banks, never settling and oh-so-beautiful and oh-so-dark in the sun-flecked grove.

Sirius' breaths were quiet and quick under his puce nipples, taut circles shadowed under his up-held arms. His armpits were black and slick from dancing, and there was a slight sheen of sweat on his belly. The light moved across his taut thighs, picking out each crease in his fabric bunched around his hips. Remus could smell him, that unmistakable smell, part wet-dog, part cloves, warm and thick in the back of his throat.

"Stay," Remus said, "don't move."

His ears questioned the hoarse crackle of his voice: some cog of his internal mechanism had ground and stuck, and the pressure was building as things sparked and creaked and strained. His scar tissue started to throb rhythmically, and light tendrils of spring air felt coarse on his face. He knelt at Sirius' feet. Blood raced furiously through his body, burning at his cheeks, across his chest, at the front of his thighs, in the soles of his feet. He levered his shoes off from the heels, with his toes, and they thudded mutedly on the floor – one, two. Sirius' breathing hitched a little, goosebumps flowing from sharp, damp nipples down his belly.

Remus wasn't conscious of his own breathing. His inner ears had begun to pop with pressure, the curls of his auricles stinging with heat. He was thumping with blood, in time to the clenching fist of his heart, his skin a burning corona gathering charge. He couldn't take his eyes off Sirius, and watched his inhalations drop into his belly, growing harder and more ragged, while his legs trembled slightly. His arms he'd kept thrown over his face, but Remus could see his mouth was half-open.

Remus ran his flaming palms along the tops of Sirius' thighs from knee to hip, his skin jumping and twitching beneath him. Sirius bucked and tightened his arms around his head when Remus' thumbs reached his hip bones. Remus folded his hands around Sirius' hips, holding on for dear life as the fire searing his every pore suddenly dropped and pooled in his guts, coalescing into an unfathomable weight sinking down between his legs.

The world was spinning and shrinking and flowing and Remus lowered his face to Sirius' navel, rubbing his cheeks against his clammy skin and the sparse, coarse hair below his bellybutton and the scrunched waistband of his boxers, his fingers clamped tight around Sirius' hips, thumbs pressed inside the crest of his pelvis. Remus was reeling, lost, was drowning in the scent and heat of him, frantic, his eyes screwed shut, not a clue what to do with this incandescent creature under his hands, thrumming and desperate for more. His chin and cheeks kept brushing against Sirius' stiffening cock, he could feel Sirius' hips straining against his grip, and he want to tear at the underwear with his teeth. He buried his face inside Sirius' thighs, into the heat of him, and groaned into his pubic bone before turning to mouth his balls through sodden fabric.

Hands wound into his hair and tugged painfully. He surfaced to find Sirius panting, "Fuck, fuck, fuck," pupils jet and blown. Sirius levered himself into a sitting position with his grip on Remus' hair, pulling Remus flush against the bedframe and his head back.

"Fuck, Remus," Sirius' chest continued to heave as his eyes searched Remus' face, and he grinned as blood flushed Remus' cheeks and sobered as his gaze caught on Remus' swollen lips. He dropped his hands from Remus' hair to Remus' forearms, and guided his trembling figure to standing, uncoiling to his feet along with him. He dragged his hands up Remus' arms to his shoulders and stepped in slightly, so the outer edge of his foot brushed up against Remus' arch, their bodies trembling in the radiant heat of the others'.

"This ok?" Sirius breathed, eyes lidded.

Remus snorted, and wrapped a hand around Sirius' jaw, tilting his face up, and kissed the corner of his mouth, and its bow, and the curve of his lower lip, and lost himself between Sirius' lips. They collided into each other, Sirius all slick skin against Remus' t-shirt and jeans, winding his limbs around Remus' and rocking on the balls of his feet, pulling Remus tighter against his hips with his belt-loops, sliding an arm between them to palm at Remus' fly and tug impatiently at his belt.

Remus slid his hand from Sirius' jaw to the back of his neck, and kneaded at Sirius' arse-cheek with the other, thumb at his sacrum and fingers pressed against the bare skin at the very top of his inner thigh, lifting Sirius up onto his toes and hard against him. Sirius swallowed obscenities and gathered handfuls of Remus' shirt in his fists, running his inner thigh up and down the outer seam of Remus' trousers. Remus' body was keening, his desire vast and ravenous and constricted in his trembling frame, in turn straining against the friction of cotton and denim. Sirius' hands were brands through his clothing, stoking fire wherever they touched, and Remus felt terror. Pressure was building, tautening his sinews, his heart racing, and he knew he was on the brink of losing control.

Sirius got tangled in their legs and brought them tumbling down on the bed, barking with laughter. He tugged up Remus' shirt and laid slow kisses on his stomach while tracing his hard-on through his jeans. Remus had no idea what to do with his hands, and squeezed his eyes shut, trying to not mumble incoherently.

"Moony, I've got to get these jeans off you. D'ya mind?"

Remus shook his head.

"No," he managed, "go ahead."

"With pleasure," Sirius chuckled, and began working at the buttons. Remus' heart galloped as the pressure at his groin lessened, rivet by rivet, and his blood sang. Sirius was propped up on an elbow and his curls brushed against Remus' exposed navel. He shivered.

"Lift up," Sirius ordered, and slid off the bed to tug off Remus' trousers. He stood and appraised Remus for a moment, in white shirt and briefs, dishevelled, skinny, scarred, and hard.

"Your turn now," he said, adjusting his boxers and smiling wickedly at Remus.

"What do you mean?"

"Tell me."

Remus sighed and pushed himself up on to his elbows, gazing at the sweaty mess of Sirius, glowing warm in a shaft of sunlight. He let his head drop back.

"What's that, Lupin?"

Remus raised his head to meet Sirius' eyes.

"Touch me, Sirius, for the love of gods."

Sirius chuckled and padded towards the bed, pulling down his boxers and stepping out of them, folding a fist around himself and moving his wrist lazily as he stood by Remus' bent knees.

"Not sure I have to, Moony, y'know. Reckon I could just…"

Remus shifted awkwardly, twitching in his briefs, his circulatory system roaring like a river undammed as Sirius ran his dark eyes over the bed.

And then Sirius knelt, and pulled Remus' waistband over his cock, and ran his fingers and tongue up and down the length of him, and swallowed him whole, and Remus lost it.

"Dammit," Sirius said, irate, and Remus sat up, coursing with sudden anxiety. "I genuinely just came all over the floor."

Remus bellowed with laughter, light with relief, the sound resonating inside, around the charred bones and soft jelly of him.

"Come here," he muttered, and Sirius grinned ("Already did, mate") and draped himself over Remus, brushing his lips over Remus' chest before settling on his shoulder.

Breezes carried birdsong and tree-rustle and snatches of conversations past the windows while the day grew hotter.
