Dennis let his lips and tongue trail down her skin, the warmth of it so familiar against his body. If she were one of his usual victims, then he'd be revelling in this warmth, knowing full well they wouldn't be feeling much else after this.
She didn't fear him in the least, and already knowing what he was, it made him just a little angered. He let out a soft growl against her skin as his mouth moved down to a nipple. He let the tip of his tongue tease the dark bud as his hand moved down between her thighs. He felt a heat radiating from between her legs, his cock grinding again against he hip. "Just one little nibble," he said softly as his lips trailed back up to her neck.
"Just a tiny nibble. I promise, you'll feel better than you've ever felt before." He sounded needy, and threw the idea out there as one of desperation, hoping she would say yes, as his hand sought to slide up her inner thigh.
