Colin had gone very...photographer-y, and it was interesting - new - to feel that look right on him. Zach hadn't really been aware at Hogwarts when Colin took pictures of him. And it was different seeing, knowing, the camera. But Zach didn't close himself off, didn't care to. He liked being with Colin, and camera or not, they were still quite intimate.
He was smiling easily, up at Colin, with his arms still moving slowly for the most part. Zach hadn't given up having that touch altogether. Simply, he was doing the touching and Colin the looking. Looking. "You are so hot," Zach muttered.
