It felt as though Hunter's senses had overtaken him, fighting off any rational thought or action. It was all sound and sight and smell, of his twin and of the couple who were still lost in each other, unaware they were watched. A slight catch of breath was the only sound from him, as Fawn's hand smoothed over his thigh. She was so close from touching the length of the erection that laid between them, but even with that distance it was searing.
"Sister," Hunter said in a low, soft growl, burying his face in her hair. He pressed through it until he reached the bare skin of her neck, and he laid his lips against it. It wasn't as though he had never touched her there, but it had always been with teasing laughter before. It had never meant... this.
