His hand

Sarah bent down slightly, and kissed his hand. In an instant, she felt energy surging through her, as well as the energy within her already, and surrounding her. It seemed absurd to think that she hadn't noticed it before, it was so obvious now, so easy to control it too. She collected some of it in her hand, and watched the soft glow. She looked at the chains that bout the demon, and could understand the magic on them. It would be simple to break it as well, if she chose to do so. She couldn't help but feel a little guilty about even thinking about just leaving him, after making the contract, but then again, he was a demon, it's not like she needed to feel bad for him, right?
