Astoria felt his hands on her shirt, knew what he was going to do and for a moment, just a tiny second, there was a hesitation, as her mother's warnings and a lifetime of doing what was proper reared it's head and made her think twice.
In the end, however, Astoria made her decision, and raised her arms over her head, unspoken consent in the gesture. She knew where this was leading, could feel it in the way Draco looked at her, the way he kissed her, and she wanted it. Needed it even. If anyone was going to be first, her only, it was going to be Draco. She'd never wanted anyone else the way she wanted, needed to be with him. She was more then willing to give herself to him, without even being asked.
