Releasing Fox from his promise was not an invitation to have sex. Frankie just didn't want him feeling as though there was a wall between them. She wanted him to feel free to kiss her and touch her and continue making her feel amazing. She'd say no if he took things too far, but it was Fox who slammed on the brakes.
At his urging, Frankie moved off of him. Once again, she was perched on her knees, gazing at him. He may have regretted his words, but few things had ever sounded so sweet to Frankie. She smiled adoringly at him. "Okay," she said with a nod, reaching out to take his hand. More kissing would have been nice, but it was clear that Fox was worried about controlling himself, so Frankie didn't push.
