Sebastian just laughed and shook his head, tightening his arms around Casper a bit in case he started to pull back. He couldn't hold back the shivers though at having the other's soft lips moving against his neck once again. "I'm not going to tell you that. You'll just have to find out for yourself if you're that curious." Even though he could feel the scars on Casper's back, he didn't say anything about them. It wasn't really that noticeable this way anyhow. Just a slight difference in how the skin felt under his fingers. Looking at them, however, would probably be very different.
