Chapter 2: Button Pusher
It had been a long night, and Severus Snape and Lucius Malfoy were lying on a sofa, too tired to even go to bed. Snape was looking down languidly, vague thoughts passing through his brain, when suddenly a finger entered his field of vision, and pressed down on a button of his coat. It was lifted up again, and moved down one button, which it also pressed down on. It repeated this several more times, before Snape spoke.
"Lucius," he said. "What are you doing?"
"Pushing your buttons." Lucius said, looking up at him with a wicked glisten in his eyes.
