"Unleashing the Beast"

Carlisle's hands moved in tandem, one spanking her ass while the other pulled her hair, sending a thrill of pain and pleasure through Isabella's body. "Fuck, you're such a slut," he growled, his voice husky with desire. "This cunt is so good, you're a cum sleeve." Isabella's eyes widened in shock, but she couldn't help the response that rose to her lips. "Oh, Daddy, I'm your little whore!" she screamed, her voice hoarse from the exertion. "Fuck me harder, Carlisle!" Carlisle's grip on her hair tightened as he pulled her head back, his eyes blazing with intensity. "You're a tight little thing, aren't you?" he whispered, his breath hot against her ear. "You love being fucked like this, don't you?" Isabella nodded, her body responding to Carlisle's touch in ways she never thought possible. "Yes, Daddy, I love it!" she screamed, her ass stinging from the spankings. "Fuck me, Carlisle, make me cum!" Carlisle's hand moved faster, spanking her ass with a rhythmic intensity that sent Isabella's body into overdrive. "You're going to cum, aren't you?" he growled, his voice low and menacing. "You're going to cum all over my cock." Isabella's response was incoherent, a jumbled mess of words and moans as she screamed "DADDY" over and over again. "Make me cum, Carlisle, please! Oh, Daddy, I'm going to cum!" As Carlisle continued to fuck her, his words became a dirty litany, each one more outrageous than the last. "You're a little cum dumpster, aren't you?" he growled, his hands moving in tandem. "You're a fuck toy, a plaything for me to use and discard." Isabella's response was a scream of pleasure, her body shuddering as she came, her pussy milking Carlisle's cock for all it was worth. As she collapsed forward, Carlisle's arms wrapped around her, holding her close as he continued to fuck her, his words a dirty whisper in her ear.
