Remus Lupin leaned against the oak bar in the Leaky Cauldron, his fingers tracing the rim of a firewhisky glass. At thirty, the lines around his eyes spoke of too many full moons and too many nights staring at the ceiling after the war. He had survived the Battle of Hogwarts, clawed his way into a Ministry post in the Werewolf Liaison Office, and built a quiet life that felt more like survival than living. The scars on his body itched under his robes whenever the moon neared fullness, reminders of nights spent locked away while the rest of the wizarding world tried to forget the war. He had seen friends fall, watched the Ministry rebuild on shaky foundations, and spent endless hours defending werewolves who still faced discrimination in Diagon Alley shops and Ministry corridors alike. The door creaked open and Sirius Black strode in, black hair tied back, leather coat dusted with Diagon Alley soot. Sirius was thirty-one now, cleared of all charges after years in Azkaban, working odd Auror consults while rebuilding the Black family name on his own terms. His eyes still carried the haunted edge of prison, yet his grin remained the same reckless one from their Hogwarts days.
They had been friends since they were eleven, brothers in all but blood through the Marauders, yet something had always simmered beneath the surface. After the war, that something had grown sharper, more dangerous. Sirius ordered a drink and slid onto the stool beside him. "Moony. Didn't expect you here on a Tuesday." Remus felt the familiar warmth spread through his chest at the old nickname, one that carried the weight of shared secrets and near-misses during the war. "Full moon was last week," Remus said, voice low. "Figured I deserved one night without paperwork." Their shoulders brushed. The contact lingered a second too long. Sirius's grey eyes flicked down to Remus's mouth, then away. They talked about the Ministry, about the lingering prejudice against werewolves, about how Sirius still woke sweating from Azkaban dreams. The conversation drifted into old memories, pranks at Hogwarts, the night they first realized the war had stolen their youth. Remus recalled the full moon nights in the Shack, how Sirius had risked everything as Padfoot to keep him company. Sirius mentioned the cave where Remus had dragged him out after a near-fatal mission, their hands clutching each other as curses flew overhead. By the time they finished their second round, the air between them crackled with unspoken history.
Sirius suggested they continue at Grimmauld Place, now stripped of its dark artifacts and renovated into something almost livable. Remus hesitated only a moment before agreeing, the pull too strong after years of careful distance. They Apparated into the manor's foyer. Moonlight slanted through tall windows, silvering the dust motes. The air smelled of old wood and faint traces of wolfsbane potion Remus kept on hand. Sirius poured two more drinks in the library, his fingers brushing Remus's as he handed over the glass. "We've been dancing around this since we were twenty, Remus. After everything, why keep pretending?" Remus set his glass down, heart pounding against his ribs. "Because you're you and I'm me. Because the Ministry watches both of us. Because friends don't ruin each other." Sirius stepped closer, heat radiating from his body. "We stopped being just friends the night you dragged me out of that cave after the war." His hand rose, thumb brushing Remus's jaw. Remus leaned into the touch, eyes closing as memories flooded in of shared glances across battlefields and quiet nights in safe houses.
The first kiss was tentative, then urgent, teeth and tongues and years of restraint shattering. Sirius pressed him against the bookshelf, hands sliding under Remus's robes, palms hot on scarred skin. They moved to the bedroom, clothes falling in a trail across the floor. Remus's body was lean from years of transformation, silver scars mapping his chest and thighs. Sirius traced each one with his mouth, murmuring apologies for every full moon spent apart. "I should have been there more," Sirius whispered against a particularly deep scar on Remus's hip. "You were fighting your own battles," Remus replied, voice rough as fingers tangled in Sirius's hair. When Sirius took him in hand, Remus groaned, hips bucking into the firm grip. The explicit rhythm built slowly, Sirius learning the sounds Remus made, the way his breath hitched when teeth grazed just so. Remus returned the favor, sinking to his knees on the worn rug, tasting salt and heat as Sirius cursed above him, hips thrusting shallowly. The manor was quiet except for their breathing and the soft wet sounds filling the room.
They tumbled onto the bed, limbs tangling. Sirius's mouth moved lower again, tongue stroking along Remus's length until Remus's fingers twisted in dark hair. He felt the press of Sirius's tongue lower still, exploring with careful patience that made Remus arch and gasp names from their past. "Padfoot, please," Remus begged, the word slipping out like an old incantation. Sirius answered by slicking his fingers and pressing inside, stretching him with slow curls that sent sparks through Remus's nerves. The explicit scene stretched on, bodies learning each other after so long apart. Remus flipped them, straddling Sirius, guiding him inside with careful patience that soon gave way to desperate thrusts. The manor echoed with skin on skin, low curses, names gasped like prayers. Sirius's hands gripped Remus's hips hard enough to bruise, meeting every movement. "Harder, Moony," Sirius urged, voice breaking. Remus leaned down for another kiss, tasting himself on Sirius's tongue. They shifted, Sirius behind him now, the new angle drawing moans from both as pace quickened. Sweat slicked their skin, the scent of arousal heavy in the air. Remus reached back to pull Sirius closer, their bodies moving in sync built from years of unspoken want. When release came, it crashed through them together, Remus spilling across the sheets while Sirius pulsed deep inside, both crying out in the quiet room.
Afterward they lay panting, sweat cooling, fingers laced. Remus rested his head on Sirius's chest, listening to the steady heartbeat of the man he had loved in silence for two decades. Sirius stroked his hair, tracing the faint lines of old scars on his back. "Stay the night. Stay the week. We'll figure the rest out," Sirius murmured, voice thick with emotion. Remus nodded, already drifting, the forbidden finally claimed as their legs remained intertwined under the sheets. A soft knock sounded from the hallway door, faint but unmistakable.
