Draco lifted his head and saw that she was on display. He'd always known that Daphne was an attractive, beautiful girl. It was hard not to notice. His mind was hazy with the pulse of arousal that beat through him but even that didn't mask the thought that he could pretend not to see her. He could erase the want from his face easily - the Malfoy Mask was a skill that his father had taught him from an early age. But why would he do that? Not when she was standing in front of him, clad in revealing delicates that left very little to the imagination. He may be a Malfoy, but he was male first and foremost and when a lovely woman showed herself off, by Merlin he was going to take notice.
He wanted to say as much but she had not given him permission to speak. Just as well, she probably wouldn't believe him even if he could say the words. Instead, he licked his lips and showed his desire without shame. He wanted her, that was obvious, and he didn't care that she could (and probably would) use that knowledge against him. She was gorgeous and he wanted her to fuck him. It was that simple.
