Daphne's reaction was more then enough to get him to move, he simply couldn't take his eyes away from her. The desire was only intensified by the fact that this was the woman that held his heart in her hand. No one had ever been able to claim that before, no one except Daphne. He'd barely had a chance to find his breath before Daphne kissed him like no one else had. He wanted to give her exactly what she wanted and he would, but he was going to follow through on that in his own time.
He didn't want this to end and took measures to ensure that it would last for as long as they could both handle it. After the initial entry, Harry returned to the languid pace he'd taken before. The initial movement of his hips pulled a low moan from his lips, though it remained muffled by their kiss. Almost immediately, he found a rhythm. Four shallow, One deep. Three Shallow, Two deep, continuing until he felt as though he couldn't possibly be any deeper inside of her before he backed off, starting the cycle all over again. It was a pattern that would drive them both insane, and Harry knew it.
It was sheer willpower alone that allowed him to continue as they were. With every little moan she gave Harry felt desire run through him, tightening the knot in him just a bit more. After one a brief period, Harry had to break the kiss, his lips finding her skin instead, working down her neck and over her collar bone, his hands find purchase on her perfect hips for barely a moment before sliding upward. He couldn't help but touch her.
