**Degradation and Desperation**

"Since you wanna be such a slut, show me," Sirius spat, his voice venomous as he shoved Regulus towards James. Regulus stumbled, his eyes wide with fear, as James's arms opened to catch him. But before James could wrap his arms around Regulus, Sirius's words cut through the air again. "Be a dumb fucking slut and ride James's fat cock." The air seemed to thicken with tension as Regulus's face went pale. James's eyes locked onto Sirius's, a mixture of concern and warning etched on his face. But Sirius just sneered, his eyes blazing with fury. Regulus's eyes darted to James, and for a moment, James thought he saw a glimmer of pleading there. But then Regulus's gaze dropped, and he slowly began to move towards James. James's arms opened, and he pulled Regulus close, his hands gentle on Regulus's hips. Sirius's eyes narrowed, his gaze fixed on Regulus as he began to undress. The buttons on Regulus's shirt came undone, and the fabric parted to reveal his pale skin underneath. James's eyes locked onto Regulus's, and he could see the fear and arousal warring for dominance. "James," Regulus whispered, his voice barely audible. James's hands moved up Regulus's thighs, his fingers gentle as he began to pull Regulus onto his lap. Regulus's legs parted, and he slowly began to lower himself onto James's cock. The sound of Regulus's ragged breathing filled the air as he began to ride James, his body trembling with fear and arousal. Sirius's eyes never left Regulus's face, his gaze burning with intensity as he watched Regulus move on James's body. James's eyes locked onto Regulus's, and he could see the mixture of emotions warring for dominance. Regulus's face was flushed, his eyes wide with fear, but also with arousal. As Regulus continued to ride James, Sirius's face twisted in disgust. "You're a slut," he spat, his voice venomous. "You're a Black, and you're a fucking whore." The words seemed to drive Regulus harder, his body moving faster on James's cock. James's hands moved up Regulus's hips, his fingers digging into Regulus's skin as he pulled him closer. Regulus's eyes locked onto James's, and for a moment, James thought he saw a glimmer of connection there. But then Sirius's words cut through the air again, his voice a harsh reminder of the degradation and desperation that filled the room. Regulus's face went pale, and he slowed to a stop, his body trembling with fear and arousal as he looked up at Sirius with a mixture of emotions.
