Chapter 7: The Family Affair

The door creaked open, and Edward's smirk illuminated the dimly lit room as he took in the scene before him. Carlisle, still thrusting into Isabella with frenzied intensity, didn't even flinch as Edward approached. Isabella, however, seemed to sense Edward's presence, her eyes fluttering open as she locked gazes with her other brother. Edward's smirk grew wider as he strode closer, his eyes fixed on Isabella's cum-stained pussy. "Looks like you're getting a good fucking, little sister," he said, his voice dripping with amusement. Carlisle grunted, his grip on Isabella's hair tightening as he continued to fuck her. Edward chuckled, dropping to his knees beside the pair. His eyes locked on Isabella's pussy, and he reached out a tongue to lick at the mixed cum pooling on her thighs. Isabella's eyes went wide, her body shuddering with pleasure as Edward's tongue made contact with her skin. "DADDYS," she screamed, her voice hoarse from her earlier cries. Edward's smirk grew even wider as he sucked her pussy, drinking in the cum that had spilled from her. Carlisle's grip on her hair tightened, his pace speeding up as he continued to fuck her. "You're a dirty little slut, Isabella," Carlisle growled, his voice low and menacing. "And now you're getting fucked by both of us." Edward's tongue danced across Isabella's clit, sending shivers down her spine. "You're a cum factory, little sister," he said, his voice muffled by her pussy. "Always producing load after load of cum for us." Isabella's response was a jumbled mess of words and moans, her body still responding to the dual assault. "DADDYS, DADDYS, FUCK ME!" she begged, her voice hoarse from her earlier cries. The air was thick with tension and lust as the three of them continued to fuck and suck, their mixed cum pooling on the floor beneath them. The room seemed to vibrate with their collective desire, and Isabella's screams grew louder, her voice hoarse from her earlier cries. As they continued to indulge in their twisted desires, Edward's smirk never wavered, his eyes gleaming with a feral intensity as he gazed at his sister. Carlisle's grip on Isabella's hair tightened, his pace speeding up as he fucked her with a frenzied intensity, and Isabella's screams grew louder, her voice hoarse from her earlier cries. The scene was one of utter depravity, the three of them lost in their own twisted world of desire and lust. And as they continued to fuck and suck, their bodies seemed to become one, their mixed cum a testament to their twisted bond.
