Eight years after the final battle Remus Lupin stood in the marble halls of the Ministry of Magic, his robes crisp and his face lined from too many nights spent poring over curse reports. At thirty-three he carried the weight of survival in every measured step, the silver at his temples a quiet reminder of full moons and battles fought long ago. The war had taken friends and left scars no glamour could hide. Sirius Black had been gone for nearly a decade, presumed lost in the aftermath when the veil between worlds thinned and swallowed him during a final skirmish. No one spoke his name anymore.
The owl arrived on a Tuesday. A single scrap of parchment: Diagon Alley, the old bookshop at midnight. Remus recognized the handwriting immediately. His chest tightened with a mix of dread and something warmer he refused to name. He Apparated there after his shift, heart hammering like he was still a boy at Hogwarts, the night air cool against his skin.
Sirius waited in the shadowed doorway, older, leaner, silver threading his dark hair. His leather jacket hung open over a faded shirt, and the years had carved sharper lines around his eyes. "Moony." The old nickname fell between them like a hex. Remus swallowed hard. "Padfoot. You look... alive." They clasped forearms, the grip lingering too long, fingers brushing the pulse points as if checking for proof that this was real. Years of unspoken grief and anger surfaced in the silence. Sirius had spent time in hiding, evading old enemies who refused to die with Voldemort. Remus had buried himself in Ministry work, pretending the Marauders were only memories.
They walked the quiet streets toward a borrowed wizarding manor on the outskirts. The cobblestones echoed under their boots. "I thought you were dead," Remus said quietly, voice steady but eyes betraying the storm inside. Sirius glanced at him. "I tried to send word, but the wards were too strong. Every time I reached out the risk was too high." The admission hung between them. Remus remembered the nights after the war, staring at the empty chair where Sirius should have been, the ache of closure never granted. The manor loomed ahead, wards flickering to life as they approached. Inside, firelight caught the scars on Sirius's knuckles, the faint tremor in his hands when he poured two glasses of firewhisky.
"I never got to say goodbye," Sirius said, voice rough. Remus turned, setting his glass down untouched. "You left us all. James. Lily. Me." The accusation hung heavy, yet the air between them crackled with something else. Tension thickened until Sirius stepped closer, the familiar scent of leather and smoke wrapping around Remus like a spell. Their kiss was desperate, teeth clashing, hands gripping robes as if afraid the other would vanish. Remus backed Sirius against the wall, fingers tracing the familiar tattoo on his chest through the fabric. "Still the same reckless idiot," Remus murmured against his mouth. Sirius laughed low, the sound vibrating through both of them.
Clothes fell away in the bedroom, robes pooling on the floor. Sirius's body was harder than Remus remembered, muscles honed by years of flight, a map of old hex scars across his ribs. Remus mapped every inch with his mouth, tasting salt and old magic, tongue tracing the line of Sirius's collarbone. Sirius groaned low, pulling Remus down onto the bed. "I missed this. Missed you, Moony. The way you always knew exactly where to touch." Remus's hand wrapped around Sirius's cock, stroking slowly at first, building rhythm, thumb circling the head until Sirius arched into the touch, hips rolling. Then Remus took him in his mouth, tongue working the length, sucking deep while Sirius's hands tangled in his hair, guiding gently. "Fuck, just like that," Sirius breathed, voice hoarse. The taste of him filled Remus's senses, the weight on his tongue grounding them both in the present.
They switched positions, Sirius pushing Remus onto the bed with a grin that still held the old Marauder mischief. He prepped him carefully with oil from the nightstand, fingers sliding inside one by one, scissoring until Remus panted and pushed back against the intrusion. "Tell me what you want," Sirius said, eyes dark. "You," Remus answered, voice breaking on the word. When Sirius entered him it was slow, filling, the burn turning to heat as he bottomed out. They moved together, thrusts deepening, skin slapping, the bed creaking under their weight. Remus wrapped his legs around Sirius's waist, meeting every push. "Harder," he demanded, nails digging into Sirius's back. Sirius complied, pounding until the headboard slammed the wall, sweat slicking their chests and the air thick with moans and the scent of sex. Remus stroked himself in time, coming first with a cry that echoed through the room, white streaks across his stomach. Sirius followed moments later, spilling inside with a shuddering groan, body trembling as he collapsed forward.
Afterward they lay tangled, breaths slowing in the dim light. Remus traced Sirius's jaw, thumb brushing the stubble. The war had stolen so much, yet this remained, a fragile thread pulling them back. A soft knock sounded at the manor door, followed by a familiar voice calling out. Sirius tensed, eyes meeting Remus's with a spark of renewed danger.
But as the knock echoed again their hands found each other once more, promising the night was far from finished.
