"Unleashing the Beast"

Sirius's eyes gleamed with a feral intensity as he gazed at Regulus, still clad in the maid outfit that had driven him wild earlier. He could see the residual flush on Regulus's cheeks, the spark of excitement in his eyes, and he knew he had to have him again. This time, he wanted to unleash his full, primal passion on Regulus, to claim him like an animal. "Get on your hands and knees," Sirius growled, his voice low and husky. Regulus's eyes widened, but he complied, his body trembling slightly as he assumed the position. Sirius stood behind him, his massive cock twitching with anticipation. He reached out and grasped Regulus's hips, his fingers digging deep into his skin. "Please," Regulus whispered, his voice barely audible. Sirius just chuckled, a low, menacing sound. He raised Regulus's hips, tilting his pelvis to receive him. Then, with a swift, powerful thrust, he plunged into Regulus's depths. Regulus's eyes rolled back, his tongue lolling out of his mouth as he was impaled on Sirius's massive cock. Sirius began to fuck Regulus with a primal ferocity, his hips pistoning back and forth with a relentless rhythm. Regulus's body was soon reduced to a mere vessel, his mind consumed by the sheer, overwhelming sensation of Sirius's cock. His thoughts began to disintegrate, melting away into a sea of pure, animalistic pleasure. As Sirius continued to pound into him, Regulus's eyes remained rolled back, his tongue hanging out of his mouth like a rag doll's. His body was a limp, quivering mass, unable to do anything but take the punishment - and the pleasure - that Sirius was dishing out. The world narrowed down to a single, all-consuming thought: Sirius's massive cock. Regulus was nothing but a mere shell, a vessel for Sirius's unbridled passion. And Sirius, lost in his own animalistic fervor, was oblivious to everything except the sensation of his cock moving in and out of Regulus's body. The room around them dissolved into nothingness, leaving only the two men, locked in a primitive, bestial dance. Time lost all meaning as Sirius continued to fuck Regulus with an unrelenting ferocity, his body driving Regulus's to the very limits of endurance. In that moment, Regulus was nothing but a mere object, a plaything for Sirius's unbridled lust. And Sirius, the predator, was in his element, his power and dominance over Regulus absolute. The only sound was the slapping of flesh on flesh, the only thought the endless, driving rhythm of Sirius's cock.
