Sirius had been sitting on a couch by the fire when James walked into the common room. He had barely glanced up, merely nodding and continuing to read the book on his lap. He felt the couch dip slightly as another body had settled in next to him.

"What'cha doin'?"

"Charms. Go away, I'm trying to work."

James theatrically sighed. "That's boring…"

"James, I have to get this done!"

The other boy didn't respond. He just bent down and pressed their lips together. Sirius was too shocked to notice when his book fell to the floor with a loud thud.
