It's Au Revoir, and Not Goodbye by Christine Carr (is it one "r" or two?) Hehe I just read that like last week.

Quote
Clark looked back and forth between the offered papers and
her face, clearly torn. Then, suddenly, his face cleared.
"I don't want to wait that long."

Before Lois could register his declaration, Clark's mouth
was on hers. Surprised, she hesitated for the briefest of
moments, but it wasn't long before she was winding her
fingers through his hair, letting the streamers fall to the
floor. His lips tasted incredibly sweet as they pulled
against hers, and when they finally separated, Lois felt as
if she'd never been kissed so thoroughly in her life.

"Wow," she breathed, her voice coming in soft pants. "That
was--"

"Yeah," Clark agreed, breathing more quickly himself.
"Definitely."
