I found it! This is from Brief Encounter, by Wendy and Yvonne. One of the very first stories I read, and always a favorite
Okay, here's a fun story
...
Lois gave herself over totally to the kiss. Clark was on one knee next to the big chair, one hand cupping her face, lips covering hers gently. She reached her hands up to hold his face, loving the feel of his lips on hers.
<He's trying to sidetrack you!>
<Who cares?>
The kiss deepened and it was some time before the two finally pulled back.
"Uh, Clark. Wow! I don't know what to say. What was that for?"
"Because it might be the last kiss I ever give you."
