Had she offered right then and there to let him feed from her, he would have called her a fool to her face. But at least there was a part of her that would take all this information and process. That's my good little Ravenclaw, take the facts and go and think on them. She would offer, and he knew he would make it irresistible.
It was still a few hours before sunrise, and he had already fed, so he had nothing else to do. "Of course I'll stay," he said softly, his hand still not wanting to leave her skin. "But I'll have to go downstairs just as the sun comes up." He knew he couldn't stay awake during the day - he'd tried.
Kissing her softly on the shoulder, he drew the covers up over them, and let her relax against him. It had been a most.... productive night.
