Darcy pressed tightly against his chest, returning the kiss and finding that she rather liked the sound he made, as well as the admission that he wanted her. The thought of actually having sex still filled her with anxiety, but so long as she had control over when it happened the first time, the butterflies weren't quite so bad.
"I'm not going to intereupt you if you're doing something important," Darcy replied with a shy giggle. Surely his desire for her was not that overwhelming. She didn't consider herself anything special, and Sebastian could indulge himself at any time with any of his slaves.
However, she could feel how much he wanted her, and experimentally, Darcy rocked her hips against him, hissing at the friction. Now that was nice.
