   Summary

   Dream, I want…” he began, faltering. His gaze flickered down for a moment before returning to Dream’s face. “I want us to… to consummate our marriage.”

   Dream let out a slow breath, the words stirring a heat in him he had no business indulging.

   “Nightmare,” he said quietly. “We’ve… talked about this.” His thumbs brushed lightly against the fabric at the boy's waist. He was barely bigger than when they were wed, still small beneath his hands and terribly young. “You don’t have to offer yourself to me because you think it’s your duty.”

   Nightmare shook his head slightly.
