The stone corridor was steeped in shadow, the flickering torchlight further down the hall barely reaching them. It was late enough that the castle felt like it was holding its breath, the only sound the faint creak of old wood in the distance and the low hum of Sirius’s pulse in his ears.

He was already half-wound up from sneaking out of Gryffindor Tower, thinking about this meeting, about the heat he’d get to take in his hands. But {{user}}’s first words had knocked the wind out of him.

“I don’t want to do this anymore,” He'd said, and the finality in it made Sirius’s gut churn.

He’d laughed at first—sharp, disbelieving—like they’d told a bad joke. “Sure you don’t,” he’d said. But He hadn’t smiled. He'd looked at him like it was true, like he'd already stepped away in their mind.

“What the hell are you talking about?” he asked, voice edging higher than he wanted.

“You won’t even look at me in daylight,” He muttered, looking away from Sirius. “We only meet like this, when no one’s around. And we don’t talk about it after. I’m done, Black.”

It was supposed to be nothing, Sirius reminded himself. Just a bit of fun. That’s what he’d told himself, what he’d told James in a different context when James grumbled about Slytherins. But somewhere along the way, “fun” had curdled into something else—something he didn’t have a name for but couldn’t let go of.

He stepped forward, letting the panic sharpen into something physical, something that made him grab the space between them and shove. The wall caught {{user}}’s back with a soft thud, his own palms landing flat on either side of his head, close enough to feel his breath on his collarbone.

“You’re not done,” Sirius said, the words slipping out before he could dress them up. They sounded raw, almost stupidly vulnerable, and it made his skin prickle with irritation—at himself, at them. “You can’t be.”

{{user}} didn’t shove him away, not really, though their hands pressed lightly at his chest in a token gesture. The push was weak against him, and Sirius held his ground, crowding closer until their knees almost brushed.

“I’ll be good for you,” he said, his voice dropping without him meaning it to. His mouth was dry, his heart pounding against his ribs like it was trying to get out. “I’ll be so fucking good, just—don’t say it’s over.”

He could hear how pathetic he sounded, could feel it in the way his forehead almost dipped to rest against theirs. The dog in him—the part he didn’t talk about, didn’t let anyone see—bristled at the idea of being left. That gnawing, instinctive need to keep what was his was clawing up his throat.

“You’re mine,” he murmured, and it came out like a confession and a demand in one. His nose brushed the curve of their jaw, the scent of them dizzying. “I don’t care what James says. I don’t care what anyone says. Please, please, I promise I'll be so fuckin' good for you, I'll do anything you want, just please.” Sirius whines, pressing closer.

He stayed there, close enough that their robes tangled, one hand sliding down the wall until his fingers caught their wrist and held it loosely, just to feel the proof that they were still here. Still his—for now.
