The room felt like it was on fire, the heat between them almost unbearable as they fought for control, both refusing to back down. The remains of their clothes were scattered haphazardly across the floor, torn off in a frenzy, as if they couldn't get rid of the barriers fast enough. Skin pressed against skin, slick with sweat, muscles tense and strained as they battled for dominance.
Sirius had Regulus pinned beneath him, his hands gripping his brother's wrists, pushing them into the mattress. His breath came in ragged gasps, his heart pounding in his chest, but there was no victory in his eyes—only the fierce determination to prove himself. To win. He leaned in, his lips grazing Regulus' jaw, his teeth scraping the sensitive skin just enough to leave a mark. A reminder.
Regulus hissed through clenched teeth, his body arching up beneath Sirius, trying to throw him off, but Sirius only pressed harder, using his weight to keep him down. "You think you're in charge?" Sirius growled, his voice low, rough. "You think you can control this?"
But Regulus wasn't done fighting. His legs hooked around Sirius' waist, pulling him closer, using the momentum to flip them over. In a swift movement, Regulus was on top, straddling Sirius, pinning him down with a sharp, defiant smirk. His breath was just as ragged, his eyes wild with the same fire that burned inside his brother.
"Always so sure of yourself, aren't you?" Regulus' voice was a whisper, but it carried the weight of years of resentment, of never being seen as more than the younger brother, the one left behind. "But not this time."
Sirius bucked beneath him, his hands grabbing at Regulus' thighs, trying to regain the upper hand, but Regulus was quick, pressing his hips down, holding Sirius in place with an almost vicious precision. The tension between them crackled in the air, thick and suffocating, the lines between hate, anger, and desire so blurred that neither of them could tell where one feeling ended and the other began.
Regulus leaned down, his lips hovering just above Sirius', his breath hot against his brother's mouth. "You always thought you were better than me," he said softly, his voice laced with bitterness. "But you forget, Sirius—I know you."
Sirius' chest rose and fell rapidly, his body vibrating with frustration and need. "You don't know anything."
Regulus smirked, a dark glint in his eyes as he pressed his lips against Sirius', claiming his mouth with a fierceness that matched the intensity of the fight between them. The kiss was brutal, possessive, a battle for control that neither of them was willing to lose.
But Regulus wasn't finished yet. With a sharp twist of his body, he broke one of his hands free from Sirius' grip and reached up, grabbing the back of Sirius' neck and pulling him down into a fierce, demanding kiss. Their mouths collided with the same intensity that had filled the air between them moments ago, but now there was something more—something raw and unspoken, a hunger that neither of them could deny any longer.
Sirius hesitated for a fraction of a second, the fight still burning in his chest, but the taste of Regulus—the heat of his lips, the desperate need behind the kiss—made it impossible to pull away. His grip on Regulus' other wrist loosened as he let himself fall into the kiss, their tongues clashing, exploring, tasting each other with a kind of reckless abandon.
It wasn't a battle anymore. It wasn't about winning or proving anything. It was about them—about everything they'd never said, everything they'd tried to ignore for too long. Sirius' hand slid from Regulus' wrist down to his side, his fingers brushing over the curve of his brother's hip as he pulled him closer, deepening the kiss.
Regulus responded immediately, his free hand now gripping Sirius' back, nails digging in slightly as he pulled him even closer. Their bodies pressed together, the heat between them intensifying, their skin slick with sweat and desire. Every touch, every kiss felt like it was burning them from the inside out, but neither of them could stop. They didn't want to stop.
Sirius shifted slightly, his body pressing more fully against Regulus, and a low, breathless moan escaped his lips as he felt the hard line of his brother's body beneath him. Regulus' hips bucked up instinctively, their arousal pressed together, sending a sharp jolt of pleasure through both of them. The sensation was overwhelming, dizzying, and it only spurred them on.
Their kisses grew more frantic, more desperate, as they lost themselves in the moment. Sirius' hands roamed over Regulus' body, tracing the contours of his chest, his stomach, before moving lower, his touch light but purposeful. Regulus shivered beneath him, his breath hitching as Sirius' hand brushed over the sensitive skin of his inner thigh.
"Sirius..." Regulus breathed, his voice rough and broken, his body arching up into his brother's touch. It wasn't a battle anymore. It wasn't about winning or proving anything. It was about them—about everything they'd buried for so long, everything they hadn't been able to say. Sirius' grip softened, his fingers sliding down Regulus' arm, tracing the lines of his brother's body as their kiss deepened. He could feel the rapid beat of Regulus' heart against his chest, a perfect mirror to his own, the heat between them only growing more intense with each passing second.
Regulus moaned softly into the kiss, the sound sending a shiver through Sirius' body. His hands found their way to Sirius' hair, tugging at the dark strands with a need that was just as urgent as it was tender. There was no more resistance, no more need to push back. He wanted this—wanted Sirius in a way he had never allowed himself to admit. His body, normally so rigid with control, relaxed beneath his brother, accepting, surrendering.
Sirius could feel the shift, the subtle change in Regulus as the tension melted away. He pulled back from the kiss, just enough to catch his breath, his forehead resting against Regulus'. Their eyes met, and for a brief moment, there was no defiance, no anger—just them, exposed, vulnerable.
"You're mine," Sirius whispered, his voice rough with desire, but there was something more behind it. A possessiveness, yes, but also a deep, unspoken need. He kissed Regulus again, slower this time, more deliberate, his hands exploring every inch of his brother's skin as if he was memorizing the feel of him.
Regulus didn't resist. He didn't argue or fight back. Instead, his legs parted, allowing Sirius to settle between them. His hands roamed over Sirius' back, nails digging in just enough to leave a mark. "Then take me," Regulus breathed, his voice low and barely more than a whisper, but the meaning was clear.
Regulus trembled under Sirius' touch, his breath catching as he felt Sirius' hands tighten around his hips, the pressure demanding, controlling. There was no hesitation now—Sirius had made up his mind, and Regulus knew it. The air between them was thick with anticipation, with the shared knowledge that this was a line they had crossed, and there was no turning back.
Sirius hovered above him, his eyes dark, intense, filled with a hunger that was almost palpable. He didn't say anything. He didn't need to. The look in his eyes told Regulus everything—this wasn't a moment for softness, for gentleness. This was Sirius taking what he had always wanted but had never allowed himself to have. And Regulus, for the first time in his life, wanted nothing more than to be taken.
Without a word, Sirius grabbed Regulus' wrists again, pinning them above his head, his grip firm, almost possessive. His other hand slid down, fingertips grazing the sensitive skin of Regulus' inner thigh, teasing, testing, as if reminding him who was in control. Regulus' body arched instinctively toward the touch, a soft gasp escaping his lips as he surrendered to the sensation. His brother's dominance wrapped around him like a vice, inescapable and undeniable.
Sirius smirked, the corner of his mouth lifting slightly as he saw the effect he had on Regulus. "You always wanted to be in control," he murmured, his voice low, taunting. "But not tonight."
With that, Sirius positioned himself, no longer holding back, no longer asking for permission. He took what he wanted, claiming Regulus in a way that left no doubt about who was in charge. The rawness of it, the intensity, was almost overwhelming. His hands dug into Regulus' skin, anchoring him, grounding him, as he moved with a purpose that was both rough and deliberate.
Regulus' breath hitched as he felt Sirius take him, his body instinctively tightening around him. It was a rush—pain and pleasure intertwined so closely that it left him dizzy, gasping for air. Every thrust was a reminder that Sirius was in control, that this moment belonged to him. He was relentless, his movements commanding, his grip on Regulus unyielding. There was no softness, no hesitation—only the fierce need to claim, to possess.
Sirius leaned in, his lips finding Regulus' neck, teeth scraping the skin there, biting down just enough to leave a mark. He wanted Regulus to remember this—to feel the weight of it, the finality of their connection. His breath was hot against Regulus' skin, his voice a low growl as he murmured, "You're mine now. No one else gets you like this."
Regulus couldn't respond—couldn't form words even if he wanted to. His body was a storm of sensation, his mind clouded with the intensity of it all. Sirius was everywhere—his hands, his mouth, his body pressing into him, claiming him in a way that felt as much emotional as it did physical. And despite everything—despite the years of distance, the anger, the resentment—Regulus found himself surrendering completely, giving in to Sirius in a way he had never allowed himself before. His mind was lost in the storm of sensations, in the feel of his brother's hands gripping him, holding him down, possessing him with every movement.
Sirius was relentless, his body moving with a rhythm that left Regulus breathless, every thrust sending waves of pleasure and pain through him. It was overwhelming, the intensity of it all, the way Sirius took control, the way he claimed every inch of him. And Regulus, who had spent so long trying to prove himself, trying to be something more, found a strange, unexpected solace in letting go. In letting Sirius take what he wanted.
Their bodies moved together, a perfect clash of fire and heat, every movement bringing them closer to the edge. Regulus could feel the tension building inside him, tightening with each passing second, the pleasure coiling low in his stomach, ready to explode. Sirius was right there with him, his breath ragged, his hands gripping Regulus' hips so tightly that it almost hurt.
Sirius pressed his forehead against Regulus', their breaths mingling in the small space between them. "Mine," he growled again, the word a declaration, a claim that left no room for argument. He pushed deeper, harder, as if trying to imprint himself on Regulus, to make sure that neither of them would ever forget this moment.
Regulus' eyes fluttered shut, his body tensing beneath Sirius as he reached the breaking point, the pleasure crashing over him in a wave so powerful it left him gasping, his back arching off the bed. Sirius followed seconds later, his grip tightening, his body shuddering as he reached his own release, the heat of it spilling between them, binding them together in a way that felt irreversible.
For a moment, neither of them moved. The room was filled with nothing but the sound of their heavy breathing, the air still thick with the heat of their bodies. Sirius' weight pressed down on Regulus, their skin slick with sweat, their hearts beating in sync as they slowly came down from the high of it all.
Sirius finally lifted his head, his eyes locking with Regulus', and for the first time in what felt like forever, there was no anger, no bitterness—just exhaustion, and something softer, something unspoken but understood between them.
"You're mine," Sirius repeated, softer now, almost a whisper. There was no malice in his voice, no challenge—just a quiet certainty that made Regulus' heart skip a beat.
Regulus swallowed, his throat dry, his body still trembling from the aftershocks of what had just happened. He didn't say anything, didn't argue or push back. Instead, he nodded, just once, his body relaxing beneath his brother's, his eyes drifting shut.
For now, in this moment, he was Sirius'. And for once, he didn't want to fight it.
