A slight rush of victory flooded through him at the sound of her gentle moan. He was doing something right. That was exactly what that noise had told him. Feeling a rush of self satisfaction, Sam pulled her against him even tighter and smiled even though Ruby couldn't see him do so. "I can do that," Sam assured her, pressing another kiss to her mouth, "and I know you're going to enjoy it. It's something that you've always secretly wanted, isn't it? You want to play in the dark. You want to be bad too." He finally slid his fingers past the fabric he'd been toying with, giving her a slight taste of what he'd been promising. She had earned it, after all. Begging. Giving in.
"It's very simple." Sam didn't kiss her. He focused his attention on touching her the right way, his knuckles brushing against the inside of her underwear as he rubbed at her in a slow and steady motion. "I want you to tell me what you want. How do you feel right now? Tell me."
No one else would let him screw around with them like this. Yet here Ruby was. Playing the part and doing it so well. Sam was sure that she was enjoying it too - she had to be, right? She was getting off on this as much as he was. And he was getting off on it. As Sam pulled Ruby closer, he knew she could feel how hard he had already gotten. For her. Only for her.
