He leaned forward, placing his hand gently on her shoulder. "Let me see," he said, his voice deep and smooth.
She scooted over to make room for him, their legs brushing against each other. He could feel his cock pressing against his jeans as he took a seat next to her, both of them unaware of the growing tension between them.
