Charlie loved vocal encouragement, and if fingers was what she needed, then fingers was what she'd get. Charlie released her thigh and shifted, pressing two fingers gently inside. He gave her a moment to adjust and then began moving his hand in and out, curling his fingers upwards, searching rhythmically for that sweet spot. He could feel she was close, and so Charlie sped up the fluid thrusting of his fingers.
"Like that, precious?" he purred against her, voice deep and rumbling. "Come on. Come undone."
He coaxed her there with his mouth and his fingers, and he felt the moment the waves started to hit her. He grinned against her, and rode it out with her, rocking into her with the waves.
