There was a slight flush in Percy's skin as his lover watched him - a sight that sent a thrill through Cass as he watched. Looking up to make sure he could see into Percy's eyes, he licked his lips slowly, then leaned forwards and ran his tongue along the length of Percy's cock.
It was gently at first, just the tip of his tongue touching the smooth skin, then, still with his eyes locked at Percy's, he reached out, taking the cock in his hand to guide it to his mouth, letting his lips slowly close around it.
