Sephiroth glanced down at Zack's form in his arms. Perhaps he didn't need permission to sleep, and even if he had Sephiroth would have granted it, even if for no other reason to see the young man so peaceful in his arms. He kissed the top of Zack's head and the strokes against his bare spine continued. His own eyes shut and Sephiroth allowed himself for a moment to savor the feeling of the warm body against his own.
Perhaps for this night he would allow himself to sleep peacefully. It had been a long time indeed since he had last allowed himself to do so.
