Thanks for the great feedback, so as per request...
Peter woke up, warm, happy and comfortable. He was lying against Caspian, covered with a blanket, and despite the ground being hard, he was enjoying snuggling against Caspian. After the kiss that he'd kissed all night in his dreams, Caspian revealed a blanket and the two snuggled down and stared above at a crack in the ceiling, which framed the stars gracefully.
Caspian stirred, tightening his arm around Peter. Peter kissed Caspian's shoulder lightly.
"We should probably return, soon, or people will come looking for us," Caspian whispered, kissing Peter's head.
"You don't want them to know?" Peter said, trying to hide the fact that he was hurt.
"I just think right now we need to focus on war, and Narnians tend to try and celebrate everything they can, so if they find out, they'll get distracted," Caspian said, "But I do want them to know, when this is all over."
Peter nodded, "I understand, and yes, they do love to celebrate." Caspian leaned in and kissed him for a long while, and then pulled back.
"However, telling Susan would be fine, I think she can keep a secret," Caspian said, stroking Peter's hair, and then sitting up.
Peter sat up too, "So, when will we see each other?"
"Nightfall."
Peter agreed and whispered, "One more kiss." Caspian leaned in, slowly, and captured Peter's lips softly, but with passionate feeling. And then they headed back to the group, holding hands until they'd have to part and just be friends again.
